We report a case of a 74-year-old female patient who presented with symptoms of burning mouth. The patient suffered from hypertension and had been using the following antihypertensive drugs: Angiotensin converting enzyme inhibitor (ACE)-ramipril with felodipine (calcium channel blocker) (Triapin-2.5mg a day) during the past year and a half. After one year of Triapin intake, symptoms of burning mouth evolved. Seven days after the replacement of the offending drug with losartan (angiotensin II receptor antagonist), the burning symptoms disappeared. This case stresses the fact that in cases of patients with oral burning, the symptoms can easily vanish after the withdrawal of the offending drug.

Ectodermal dysplasias (ED) are group of genetically heterogenous conditions that are characterized by abnormal development of ectodermal structures. The most affected structures are teeth, skin and its derivatives (hair, sweat glands) along with other ectodermal structures. The purpose of this work was to present the family with four boys affected with ED. We described the clinical report of male infant (affected twin) aged two months and his older brothers with absence of eyebrows and eyelashes, saddle nose, dry flaky skin, rare thin blond hair, and large number of dental anomalies with pathohistological-skin positive analysis for ectodermal dysplasia. Only a few abnormally formed teeth erupted (microdontia and conical teeth) and at the later then average age. Radiographic examination confirmed previous clinical findings and determined taurodontism of the molar teeth. They also presented pseudoprognathism of the mandible due to micrognathism of the maxilla.
Based on the positive family history (two older brothers), clinical picture and pathohistological findings of the skin we concluded that the child (and his twin brother) were also affected. EDA gene missense mutation, Ala349Thr (GCA --> ACA), was responsible for the condition of observed family. Hair hypotriyhosis, brittle, scanty hair, absent or scanty eyelashes and eyebrows, blonde, fine scalp hair, as minor clinical signs at grandmother and only scanty eyelashes at mother were observed. Mutation analysis in families with X-linked ED help in genetic counseling, prenatal diagnosis, and confirmation of carrier status.

This study was conducted to determine the effect of variable magnetic fields (VMF) on broccoli seeds (Brassica oleracea L.) pre-imbibed for 1h to improve their germination and early growth. The experiment was conducted at IPN - ESIME Zacatenco, Mexico DF, between October and November 2013.Seeds were treated with variable magnetic fieldat17, 24and 55mT for 1, 5, 7.5 and 10min.Final germination percentage, germination velocity index, fresh and dry weight and average hypocotyl length were evaluated. The magnetic field treatment of 17mT for 7.5min significantly increased fresh and dry weight by 5.7 and 8% respectively, and got on final germination percentage and germination velocity index, a positive effect but without significant differences compared to control and other treatments. However, at 55mT for 5min fresh and dry weight significantly diminished to 11.7% and 8.2% respectively, getting the lowest variables of growth compared to control and other treatments. At 17mT for 7.5min, fresh and dry weight obtained were the highest. Meanwhile, the stimulation with 55mT for 5 min showed the highest inhibition, in fresh and dry weight. It can be concluded that variable magnetic field treatment can be a suitable option to increase some germination and early growth variables of broccoli seeds.

S. Abbasi, A. Baghizadeh, G. Mohammadi-Nejad, B. Nakhoda

Annual Research & Review in Biology, Page 3636-3644
DOI: 10.9734/ARRB/2014/7565

Aims: Increasing yield is the most important aim in any breeding program. Since yield is a complex trait with low inheritance and involves several quantitative components, its direct study is not usually sufficient and therefore it is suggested that its components be investigated instead. Awareness of gene action of traits is very important in plant breeding methods.
Study Design: The experiment was conducted using a randomized complete block design with two replications for each generation.
Place and Duration of Study: P1, P2, F2, F3 and F4 generations of a Gaspard (sensitive) × Kharchia (tolerant) cross were used as genetic materials. The parents and F2, F3 and F4 populations were grown in 2010-2011 growing season in the research farm of international center for sciences, High Technology & Environmental Science-Kerman Iran.
Methodology:
Generation mean analysis using parents (Gaspard & Kharchia) and their progenies (F2, F3, F4) was used to study the type of gene action and the best genetically model of traits under drought stress condition.
Results: Generation mean analysis was performed by scaling test. Meanwhile, the three parameter model the additive-dominance was adequate to demonstrate the genetic variation and it is important in the inheritance of spike length with awn, flag leaf length and flag leaf width. Generation means analysis revealed all types of gene action (additive, dominance and epistatic) were involved in the inheritance of grain yield, plant height, spike length and total spike weight of plant. In inheritance the peduncle length, number of grain per plant were effective additive effect and additive × additive epistatic effect. Dominance effects were more important than additive effects in most traits.
Conclusion: Therefore to improve these traits hybridization and using of hybrid vigor would be much efficient than the selection strategies.

Annual Research & Review in Biology, Page 3645-3655
DOI: 10.9734/ARRB/2014/8419

Background: Dentists see many patients with undiagnosed or diagnosed HIV and Hepatitis B infection, posing threat to both doctor and patients. The aim of this study was to investigate dental students’ knowledge, awareness and attitude towards HIV and Hepatitis B patients.
Methods: A self-administered questionnaire was given to 164 clinical dental students in Kuala lumpur.
Findings: A significant percentage (49%) of the students did not know that HBV is transmitted via saliva. Female students were consistently more knowledgeable and had positive attitude towards such patients. Students had sufficient knowledge about the importance of double-gloving (69%). They displayed in consistent knowledge about the difference in infection potential of HBV and HIV. Most students (87.3%) were aware of the possibility of accidental exposure during recapping needles and spraying biological material but they were not aware about other accidental exposures. 87% students agreed that they require more training to treat patients with HIV or HBV.88.3% students considered all patients potentially infectious and agreed (80.3%) to treat such patients in future only under close clinical supervision. Fewer students agreed to voluntarily serve at an HIV or HBV specialist center (30.6%).
Conclusion: The level of knowledge and awareness of dental students about HIV and HBV was not sufficient, which renders them to danger of contracting infection while performing clinical procedures. Although a majority of the students had good knowledge, only few had professional attitudes about treating patients with HIV/HBV. Most were in favor of receiving more training to treat these patients efficiently.

Seyed Nabiladdin Fatemi

Annual Research & Review in Biology, Page 3656-3665
DOI: 10.9734/ARRB/2014/9970

Salinity, a severe environmental factor, has limited the growth and productivity of crops. Many compounds have been applied to minimize the harmful effects of salt stress on plant growth. A laboratory experiment was carried out to assess the effects of seed priming with ascorbic acid (ASA) on germination characteristics of sunflower (Helianthus annuus L.). The seeds were treated with different concentrations of ASA (0, 1 and 2 mM) before germination, then the primed seeds were germinated under salinity stress conditions using different concentrations of NaCl (0, 100 and 200 mM). Some germination characteristics including germination percentage, germination rate, seed stamina index, hypocotyl dry weight, radicle dry weight, relative water content and ion leakage were measured after imposing salinity stress for 8 days. Salinity stress caused a significant reduction in germination and seedling growth of sunflower. Seeds primed with various concentrations of ascorbic acid proved to be effective in salinity tolerance at the germination stage of sunflower. In general, priming with 2 mM ascorbic acid was more effective than the other concentrations.

Annual Research & Review in Biology, Page 3666-3686
DOI: 10.9734/ARRB/2014/10893

Objectives: This work focuses on the effect of cigarette smoke exposure toxicity on the ultrastructure of selected albino rats’ cardiovascular and respiratory systems tissues from and their recovery within three months after exposure.
Materials and Methods: Sixty male albino rats (Rattus norvegicus) were used in this study. Two groups, each consists of thirty rats. The first group was exposed to the cigarette smoke for three months on a daily basis, using a special modified smoking machine, while the second group (control) was left untreated. The exposure to smoking was followed by a period of three months of non-exposure to smoking as a recovery period. Following each period, the ultrastructural study was performed.
Results: Cigarette smoke caused ultrastructural changes in the tracheal epithelium, heart ventricles and lung alveoli. Thin section of tracheal epithelium showed low number of cilia, a high degree of cytoplasmic vacuolization. Mitochondria aggregates in the apical portion of epithelial cells, inclusion bodies are present, and disrupted endoplasmic reticulums were also observed. The alveolar epithelium showed damaged multilamellar bodies of type II pneumocyte, together with cytoplasmic vacuolization and chromatin condensation, membrane blebs projecting from the cytoplasm, and degeneration of alveolar epithelium. The ventricular cardiomyocytes revealed mitochondria with deteriorated and partially disrupted or disappeared cristae. Also it showed areas with disrupted Z-discs. After the recovery period, those tissues showed partial recovery.
Conclusion: Smoking induces ultrastructural changes in the respiratory passages and heart that affects the gaseous exchange and may predispose to cancerous changes due to accumulation of toxic and carcinogenic compounds, chromatin condensation and tissue inflammation. Cessation of exposure to cigarette smoking is important in returning most these changes to their normal ultrastructure.

DOI: 10.9734/ARRB/2014/11089

The present study was carried out to show the effect of brassinolide on normal and salt stressed wheat plant. Grains of wheat (Triticum aestivum sakha 93) were divided into four groups: seeds supplemented with 20 ml distilled water (control); seeds treated with NaCl solutions (25, 50, 100, and 200 mM); seeds supplemented with 0.1, 0.5, 1 and 2 mgL-1brassinolide and seeds treated with a combination of 1mg.L-1brassinolide and the mentioned NaCl concentrations. Root and shoot lengths, fresh and dry weights were measured as indicators for growth and biomass assessments while carbohydrates, proteins, amylase and protease were estimated as indicator for metabolic activity. Treatment of wheat seeds with different concentrations of brassinolide particularly 1mgL-1 causes a significant increase in growth parameters, carbohydrate fractions, total soluble proteins in root and shoot and the hydrolytic enzymes amylase and protease. Gradual increase in NaCl concentrations from 25mM to 200mM sharply decreased growth compared with the control. Results of this investigation showed that 1mgL-1brassinolide counteracted the inhibitory effects of salinity.

Parasitic gastroenteritis is one of the most common illnesses in humans worldwide. Most studies on gastroenteritis have focused on viral and bacterial infections, while parasitic enteropathogens and especially intestinal protozoan parasites may play a role that has not been well studied. The aim of this study is to identify the prevalence of enteropathogenic parasites and sporozoan protozoa in patients with gastroenteritis in selected hospitals in seven provinces of Iran.
Methods: In this cross-sectional study, randomly 4200 stool specimens were obtained from patients with gastroenteritis in selected hospitals. Primarily samples were examined directly for enteroparasites. The samples were filtered and concentrated by using the Paraseb Kit; and fixed, and stained by different methods including acid-fast staining, Auramin phenol fluorescence staining, and Giemsa staining were observed using light microscopy under various magnifications.
Results: The results revealed the overall rate of parasitic infection was 2.4% in the studied population. The highest rate of infection was observed in the 0-10 year age-group (47.2%). Among the infected patients, 59.5% were male and the rest were female patients.
In the studied regions, Tehran and Mazandaran had the highest and the lowest frequency with 41 (97%), and 2 (47%) cases respectively. Gastroenteritis was found in patients infected with Cryptosporidium, Microsporidium, Isospora and Cyclospora, 13 cases in total (0.3%) with 5 (0.12%), 4 (0.09%), 3 (0.07%) and 1 (0.02%) cases for all four parasites respectively. Parasitic enteropathogens were detected in 88 cases of all studied cases (2.09%). Among these observed parasitic enteropathogens, Giardia lamblia with 42 cases (1%) had the highest rate of infection, The observed frequency of infection for Blastocystis Hominis, Entamoeba histolytica, were 21 (0.5%), and 20 (0.47%) cases respectively while for the rest was 10 cases.
Conclusion: Despite a relatively low prevalence of sporozoans group, Giardia was the most prevalent agent for gastroenteritis (1%) parasitic infections in Iran, specifically in Tehran with the highest rate in children (0-10 year age-group). High frequency of Blastocystis hominis and co-infection of Giardia lamblia and Blastocystis hominis implies possible interactions between enteropathogens in a host, which require more studies to be clarified. The study also showed presented knowledge of personal and community health and hygiene needs to be more emphasized.

DOI: 10.9734/ARRB/2014/11778

Aims: The evaluation of the neuronal excitability of dentate gyrus granule cells during the development of epilepsy in pilocarpine model of TLE in rats.
Place and Duration of Study: Neuroscience Research Center, Shahid Beheshti University of Medical Sciences, Tehran, Iran, between October 2012 and January 2013.
Methodology: Status epilepticus (SE) was induced by pilocarpine injection (350mg/kg; i.p) to male rats. Twenty minutes before pilocarpine injection, N-methyl scopolamine (1mg/kg; s. c) was injected to reduce peripheral effects of pilocarpine and after 3h, diazepam (4 mg/kg; i. p) was injected to stop seizures. Twenty four hour (acute phase) and 30 days (chronic phase) after inducing SE, the excitability of granule cells was evaluated using whole cell patch clamp recording.
Results: Fifty seven percent of granule cells in the acute phase were hyperexcitable and another 43% of cells were less excitable. In chronic phase, the majority of cells (71%) were hyperexcitable, while 29% of the cells had a low excitability. In both phases of epilepsy, membrane input resistance (Rin) in hyperexcitable cells was similar to that of control group, while Rin was significantly lower in less excitable cells compared to control group.
Conclusion: Results showed the presence of two groups of granule cells in pilocarpine-induced SE in rats: one group of cells with high excitability and another group of cells with less excitability. Although less excitability might, at least partly, protect granule cells from seizure-induced neurotoxicity, but hyperexcitability in majority of granule cells and the occurrence of spontaneous recurrent seizures during chronic phase suggest the existence of insufficient compensatory mechanisms, possibly facilitating the propagation of seizure activity.

DOI: 10.9734/ARRB/2014/10173

Surface treatment of Mg alloys is a major approach for its enhanced use as orthopedic implants. In this paper, the in vitro bioactivity, mechanical stability and cytocompatibility of the AZ91 Mg alloy coated by anodic spark deposition (ASD) method are studied. The cytocompatibility behavior is examined by culturing L-929 fibroblast on the surface of the uncoated and ASD-coated AZ91 Mg substrates. The results showed that the corrosion resistance, in vitro bioactivity, mechanical stability and cytocompatibility of biodegradable Mg alloy were improved by ASD coating. Reduction of the degradation rate by ASD coating not only created a relatively stable interface for the cell adhesion and growth, but also arrested the release of corrosion products to reduce the cytotoxicity, hence, resulting in the enhanced cytocompatibility.

Annual Research & Review in Biology, Page 3734-3741
DOI: 10.9734/ARRB/2014/10788

Aims: We intended to report H. pylori seroprevalence and identify socio-demographic risk factors in dyspeptic patients and non-dyspeptic control subjects of Islamabad, Pakistan.
Methodology: Subjects were analyzed in two study groups; Dyspeptic patients on the basis of Rome III criteria (n=196) and non-dyspeptic control subjects (n=118). H. pylori status was determined using a commercial ELISA kit and its association was determined with risk factors such as age, sex, body mass index, marital status, educational level, residence, income group, use of NSAIDs and tobacco.
Results: Our results showed similar seroprevalence of about 53% in both the groups. Low education (p=.03) and lower socioeconomic status (p=.03) were significant predictors of H. pylori seropositivity in dyspeptic patients whereas increasing age (p<.001), lower education (p =.04) and married status (p=.02) were significantly associated with H. pylori seropositivity in non-dyspeptic controls.
Conclusions: Lower education and low socioeconomic status are significant risk factors in dyspeptic patients as compared to old age, lower education and married subjects in non-dyspeptic control subjects.

Annual Research & Review in Biology, Page 3742-3750
DOI: 10.9734/ARRB/2014/11058

Aims: We aim to evaluate and compare the antimicrobial activity of extracts from the leaves and stems of Ocimum tenuiflorum L. Various extractions in different solvents were compared to determine the extract with the best performance against bacteria, fungi, and yeasts.
Study Design: Prospective.
Place and Duration of Study: Food Technology Division, School of Industrial Technology
Universiti Sains Malaysia, 11800 Minden, Penang, Malaysia. This study was developed as prospective.
Methodology: Different extracts of non-polar and polar solvents were obtained from the macerate method from leaves and stems of O. tenuiflorum. The antimicrobial activities of these extracts were evaluated against selected Gram-positive and Gram-negative bacteria and fungal and yeast strains via the following method: inhibition zone, minimum inhibitory concentration (MIC), minimum fungicidal concentration (MFC), and minimum bactericidal concentration (MBC).
Results: The antimicrobial activity tests were performed using common pathogenic bacteria (Escherichia coli, Salmonella typhimurium, Klebsiella pneumoniae, Bacillus cereus, Bacillus subtilis, Staphylococcus aureus, and Listeria monocytogenes), yeast (Candida tropicalis and Saccharomyces cerevisiae), and fungus (Aspergillus niger and Penicillum sp.). O. tenuiflorum L. stem or leaf extracts were more or less active against most of the tested pathogenic strains. The inhibition zone ranged from ≥9 mm to ≤15 mm. The most susceptible bacterium and fungus were L. monocytogenes (IZ=≥10–14 mm; MIC = 6.5mg/ml) and A. niger (IZ = ≥15 mm; MFC = 3.12 mm), respectively.
Conclusion: The methanol and hexane extracts of O. tenuiflorum L. showed antimicrobial activities and exhibited significant potential as natural antimicrobial agents. By contrast, the water, ethyl acetate, and chloroform extracts from the leaves and stems of O. tenuiflorum L. can inhibit the microorganisms. All extracts from the leaves and stems failed to inhibit the E. coli, S. typhimurium, S. aureus, and C. tropicalis. However, further studies are still required.

Annual Research & Review in Biology, Page 3758-3770
DOI: 10.9734/ARRB/2014/11530

Introduction: The direct effect of parenteral nutrition on secretion of regulatory peptides in infants has not been yet reported.
Aim: The aim of the study was the analysis of secretion of chosen regulatory peptides from the gut and adipose tissue in parenterally fed infants comparing to children fed orally as well as hydrated intravenously.
Materials and Methods: In this study, the response of glucose, ghrelin, leptin, PYY, GLP-1 and adiponectin to the enteral and parenteral feeding in babies has been investigated. We compared three groups of infants: formula-fed infants, infants on TPN and fasted, awaiting for general anaesthesia before CT examination, receiving an i.v. 5% glucose/saline mixture. The blood samples were taken in first group prior and 60 minutes after feeding, in the second in continuous course of TPN and third after 8 hours fasting.
Results: Oral feeding does not influence plasma concentrations of leptin and adiponectin in infants. The ghrelin plasma concentrations during the total parenteral nutrition mimics the postprandial levels observed in enterally fed children. A significant positive correlation was found between calorie intake and adiponectin concentration (r=0.76, p<0.001); and calorie intake and PYY concentration (r=0.76, p<0.001) as well CCK (r=0.50; p<0,005).
Conclusions: The lack of fasting/postprandial modulation of secretion of gut peptides might be responsible for disturbed development of parenterally fed children. Adiponectin and PYY are the putative marker of short-term energy balance.

S. Rafiei Tabatabaei, F. Fallah, F. Shiva, A. R. Shamshiri, M. Hajia, M. Navidinia, A. Karimi, M. Rahbar

Annual Research & Review in Biology, Page 3780-3790
DOI: 10.9734/ARRB/2014/6608

Background: Streptococcus pneumoniae (S. pneumoniae), is a major pathogen causing invasive disease, colonizes the nasopharynx constituting a potential source of infection in both children and adults.
Aims: To identify the rate of pneumococcal nasopharyngeal colonization in healthy infants <2 years of age and to define the prevalent serotypes.
Materials and Methods: This cross-sectional study was performed for three months from June to August 2009 on healthy children, aged 6, 12 and 18 months visiting Health centers for routine vaccinations. Trained personnel collected nasopharyngeal samples through flexible nasal swabs and sent the specimens for diagnosis of pneumococci; after DNA extraction, microorganisms were serotyped by Multiplex PCR assay.
Results: One thousand two hundred ninety one samples were collected. S. pneumoniae was identified in 34%. A total of 761 identified S. pneumoniae, belonging to 30 different serotypes were recovered from 441 positive nasopharyngeal specimens. Serotypes 19, 6, 14, 19F, 17, 21, 20, 12F, 11 and three were most common, isolated in frequencies of 8.2, 7.6, 7.2, 7.2, 6.4, 5.3, 5.1, 4.8, 4.5 and 4.3% respectively. There was no significant difference in the diagnosed serotypes from the three age groups. Eleven serotypes (38.5%) are included in the 13-valent pneumococcal conjugate vaccine, (PCV 13). Colonization with more than one strain was seen in 228 samples, (52% of carriers).
Conclusion: Our findings revealed a significant rate of nasopharyngeal colonization with S. pneumoniae in young carriers; and draw attention to fact that only 38.5% of the isolated serotypes are included in PCV 13, demonstrating limited coverage of the current vaccine. There is a need to manufacture vaccines with an optimal formulation that would provide effective protection against serotypes prevalent in the community.

Morphological Seeds Descriptors for Characterize and Differentiate Genotypes of Opuntia (Cactaceae, Opuntioideae)

Samir Samah, Ernestina Valadez-Moctezuma

Annual Research & Review in Biology, Page 3791-3809
DOI: 10.9734/ARRB/2014/11606

Aims: In this paper, a morphometric study was carried out to analyze the variation of seeds of Opuntia accessions using several statistical approaches. The main objective was to select morphological seeds variables for characterization and differentiation of Opuntia genotypes.
Place and Duration of Study: The research was conducted in Crops Science Department of the Chapingo Autonomous University, Mexico. The sample collection was down in 2012. Seed data was obtained during 2013.
Methodology: A total of 110 Opuntia accessions (some classified and other ones with no specific taxonomic assignation), one accession of Cylindropuntia sp. (Cactaceae, Opuntioideae) and two other outgroups (Cactaceae, Pachycereae) were used. Nineteen internal and external seeds variables were obtained using image analysis. Basic statistical analysis, analysis of variance, principal component analysis, cluster and discriminant analysis were performed.
Results: Highly significant differences among accessions for all seed characters were showed. The most of the variables showed a coefficient of variation less than 10%. From de 19 variables studied, two variables did not contribute significantly to discriminate between accessions as determined by Step wise Discriminant Analysis. The principal components analysis showed that the first three components accounted for 83.35% of the variability; the first component contributed twice the variability (48.12%) respect to the second one (23.77%). Tukey's test determined that the Feret diameter and seed area were the most discriminating variables between the 7 groups resulting from de cluster analysis.
Conclusion: The selected variables, using several statistical approaches, were of interest for the characterization and identification of the different Opuntiageno types. The morphological seed characteristics responsible for the separation between genotypes were Area, Major Axis Length, Minor Axis Length, Feret Diameter and Weight. These variables have a high discriminatory power and can be taken into account as potential parameters for genotypes assignation within the Opuntia genus.

Sayak Ganguli, Abhijit Datta

Annual Research & Review in Biology, Page 3810-3815
DOI: 10.9734/ARRB/2014/10728

Aims: Glutathione peroxidases in plants have diverse roles in the maintenance of redox homeostasis in conditions of stress. The studies involving this group of enzymes have clearly demonstrated that they are near homologues to animal phospholipid hydroperoxide glutathione peroxidases with cysteine replacing selenocysteine at the sites of interaction for ligands. Phylogenetic insights of the group should provide us with indications regarding the transition of the residues needed for interactions throughout the lineage of plants for this enzyme right from the aquatic members through land plants and to the highest evolved plant groups.
Study Design: Glutathione peroxidase gene sets along with other peroxidase gene sets were retrieved from the existing databases and self organizing maps were generated.
Place and Duration of the Study: The entire study was performed at the DBT Centre for Bioinformatics, Presidency University, Kolkata for a period of June 2013 to January 2014.
Methodology: A comparative clustering was performed using self organizing maps – A technique for comparative unsupervised learning and standard neighbor joining and UPGMA methods of tree generation to identify and delineate clusters of glutathione peroxidase genes.
Results: Homology in clustering was observed when the phylogentic tree and the self organizing maps were compared. Specific sister groups were found to occupy unique areas as part of the self organizing map.
Conclusion: Observation and results indicate that GPX evolution follows the trend of plant transitory evolution.

Annual Research & Review in Biology, Page 3835-3847
DOI: 10.9734/ARRB/2014/10641

The effect of Cadmium stress on plant growth, oxidative stress and antioxidant enzyme of wheat seedlings (Triticum durum Desf.) was evaluated in this study. Cadmium stress decreased plant growth, lowered the relative water content and caused oxidative damage, as characterised by increased antioxidative enzymes in wheat leaves such as ascorbate peroxidase (APX), guaÑ—acol peroxidase (POX) and catalase (CAT). As a response to increasing Cadmium supply particular increases in antioxidative mechanisms in wheat cultivar Simeto suggest that the high Cadmium sensitivity of Simeto is related to enhanced production and oxidative damage of reactive oxygen species.

DOI: 10.9734/ARRB/2014/11165

Background: The genus Cyperus with six subgenera and 45 species is the second largest genus of the Cyperaceae family based on Flora Iranica. This genus includes 23 species in Iran, of which five are located in Northeast of the country.
Aims: We determine the taxonomic boundaries among species of the genus Cyperus distributed in Northeast of Iran by using morphological and nut micro-morphological characters.
Study Design: Morphometric and nut micro-morphology studies of species of Cyperus in northeast of Iran.
Place and Duration of Study: Ferdowsi University of Mashhad Herbarium (FUMH), specimens collected during the growing season 2010 in Northeast of Iran (including three provinces of Khorassan Shomali, Khorassan Jonoubi, and Khorassan Razavi).
Methodology: We numerically examined 43 morphological characters, nine morphological and nut micro-morphological traits on 80 herbarium specimens in order to determine the taxonomic value of the features and also to better discriminate Cyperus species distributed in Northeast of Iran.
Results: The results revealed that morphological characters are somewhat useful to discriminate species of the genus in the region under study. Scatter plot displayed two distinct groups among samples. Individuals of C. longus are accommodated in the first group. Second group is divided into two subgroups. Individuals of Cyperus rotundus are located in first subgroup. Second subgroup is showed to be more complex by consisting of C. laevigatus subsp. distachyos, C. fuscus and C. glaber. The results obtained from stereomicroscope study indicated that nut of C. laevigatus subsp. distachyos is lenticular but nuts of other species are trigonous. The results of scanning electron microscope study revealed that C. laevigatus subsp. distachyos differentiated completely in terms of nut micro-morphology from the other species.
Conclusion: The results confirm fully results obtained from previously anatomical study of these species. Also the scanning electron microscope study indicated that three species including C. rotundus, C. longus and C. glaber are similar in terms of nut micro-morphology.

Annual Research & Review in Biology, Page 3904-3914
DOI: 10.9734/ARRB/2014/8499

Aims: Wheat cultivation is still difficult to control because it faces several biotic and abiotic stresses. The transfer of resistance in wheat plants to these stresses through traditional approaches remains limited. However, genetic transformation allows the acquisition of this tolerance while overcoming the difficulties of classical improvement.
Methodology: In this context, immature embryos of two Moroccan bread wheat varieties (‘Massira’ and ‘Arréhane’) and the pBY520 plasmid containing the HVA1 gene for drought tolerance as well as the gene bar selection marker for resistance to the herbicide phosphinothricin were used in this study for bombardment protocol.
Results: The percentage of calli bombarded with regenerated plantlets was 23.92 % for the variety ‘Massira’ and 5.26% for the variety ‘Arréhane’. The selection was carried out on ½ MS rooting medium lacking hormones and supplemented with phosphinothricin (3 mg l-1); 4.36% and 6% of plantlets of varieties ‘Massira’ and ‘Arréhane’ respectively survived. The resistant plantlets were transferred to the greenhouse and the evaluation of the expression of the bar gene in leaves was positive about 60%. The confirmation by molecular analysis revealed only a transformation efficiency of 0.52 % for the variety ‘Arréhane’.

Annual Research & Review in Biology, Page 3915-3931
DOI: 10.9734/ARRB/2014/11395

Aims: Microbial characterization of contaminants on Scientific Collections in a Specialized Library.
Study Design: Selection and segregation of books from special collections, followed by an investigation of the fungal contamination through molecular biology.
Place and Duration of Study: Museu de Astronomia e Ciências Afins, located in Rio de Janeiro, Brazil, during seven months.
Methodology: Several books with a clear fungal contamination on their surface and several air samples from distinct locations in the library were included. Classical microbiological identification, molecular biology techniques and chemical treatment after flooding and cleaning of surfaces and books were performed.
Results: Results indicated that mainly cosmopolitan species were found in the environment and on the surface of selected books. Most species presented potential cellulolytic action and are toxin producers. Some unusual species were found such as Periconia, Hypocrea and Pestalotiopsis. Due to this unusual occurrence concentrations higher than 200mg/L were necessary to decontaminate the area and surfaces of the library after flooding.
Conclusion: The rapid action of the staff to solve the problems associated with the flooding in the scientific library of the Museum of Astronomy and Related Sciences in Rio de Janeiro, proved to be essential to minimize higher damage that could occur on rare books and special collections. The cooperative work involving Chemistry, Classical Microbiology, Molecular Biology and Preventive Conservation proved that the integrated practices among professionals of several areas were essential to ensure a free public access to documentation and books of interest for the scientific society. The multidisciplinary work involving Chemistry, Biology and Molecular Biology led to important conclusions about the presence of cosmopolitan fungi in the air and in selected books, their DNA characterization and their resistance to a fungistatic compound.

Mahdieh Anoush, Ali Jani, Mohammad Reza Jafari

Annual Research & Review in Biology, Page 3932-3944
DOI: 10.9734/ARRB/2014/11609

Aims: The aim of this study was to evaluate the possible effects of estradiol valerate and a specific estrogen receptor modulator, raloxifene on passive avoidance learning in male mice and to determine whether there is an interaction between estrogen receptor binding drugs and morphine.
Study Design: In this study, the state-dependent learning for morphine was evaluated at the first step, and then the effects of raloxifene and estradiol on this characteristic of morphine was evaluated. Besides the later two drugs’ independent effect on passive avoidance learning was studied too.
Place and Duration of Study: All the experiments carried out in the pharmacology laboratory, School of Pharmacy, Zanjan University of Medical Sciences between April-July 2013.
Methodology: In this study, 120 Male NMRI mice were used according to the guidelines for animal ethics. State dependent learning (as one of the usual methods for assessment of passive avoidance learning) was performed using a step down shuttle box. During training, mice were shocked only after they step down on from the queue. Latencies to step down are recorded to assess passive avoidance short term memory. Prior training they received saline or morphine and before testing session the animals received saline or morphine plus estrogen valerate or raloxifene in relevant groups.
Results: The results illustrated that pre-training administration of morphine, induced amnesia which was retained by a similar pre-test dose (morphine state dependent learning). Pre-test estradiol valerate injection was able not only to retrieve morphine induced amnesia but also improved morphine state-dependent learning. On the other hand, raloxifene had no effect on memory retrieval itself, but decreased morphine state dependent learning.
Conclusion: The results of this study indicated that estrogen receptor modulators not only are able to manipulate the learning patterns, but also there might be an interaction between these drugs and morphine induced state dependent learning in mice.

Ali Bazand, Mahmoud Otroshy, Mohammad Fazilati, Hossein Piri, Arash Mokhtari

Annual Research & Review in Biology, Page 3962-3969
DOI: 10.9734/ARRB/2014/11093

Phalaenopsis amabilis (L.) Blume is economically ornamental species of epiphytic orchids, considered for its evergreen and clustered foliage and pendulous racemes containing several yellow-green flowers. Conventional propagation of Phalaenopsis amabilis (L.) Blume restricted by unsatisfactory rhizogenesis of shoot cutting or germination problems of lack of endosperm and low seed viability. In order to investigate the effects of some plant growth regulators on seed germination and development of protocorm and seedling of Phalaenopsis amabilis (L.) Blume disinfected capsules (21 wap) was longitudinally cutted by scalpel and its content were immediately transferred to test tube containing about 30ml MS medium supplemented by different concentration and combinations of NAA, 2,4-D and BAP. The highest value of germination percentage (83.75%) was occurred in NAA (1.5mgl-1) or combination of BAP (0.5mgl-1) + NAA (0.5mgl-1) on after/during25thday. Plant growth regulators highly affected the initiation time of protocorm formation and shortest time (53.50 days) was recorded in MS medium supplemented by NAA (1mgl-1) + BAP (1mgl-1). The best time (157.50 days) for seedling development was observed in NAA (1mgl-1) + BAP (1mgl-1) and 2, 4-D (0.5mgl-1) + NAA (1mgl-1) combination treatments.

Olumide Abiodun, John Sotunsa, Edward Jagun

Annual Research & Review in Biology, Page 3980-3992
DOI: 10.9734/ARRB/2014/11739

Aims: HIV in sub-Saharan Africa is closely linked to the sexual behavior of the population. The knowledge of the impact of socio- demographic and an increasing religious movement, on risk behavior for HIV/AIDS among University students in Nigeria and the rest of the sub-Saharan Africa is uncertain and even contradictory. The aim of this study was to investigate the role of socio-demographic and religious factors in determining risk behavior for HIV/AIDS among University students in Ilishan, Nigeria.
Methodology: This is a cross-sectional study of 1225 university students selected by probability sampling method. Data were collected using an expert validated questionnaire. Data were collected on dependent variables i.e. being sexually active, having multiple sexual partners and inconsistent condom use, and the independent variables that included demographic, social and religious factors.
Results: About a quarter 24.1% of the participants were sexually active, with a higher proportion of males being sexually active (p=0.000). Among the participants who were sexually active, 34.2% had multiple sexual partners within the preceding six months and 53.9% of them did not use condoms consistently. Males (OR=1.646), Young adults (OR=1.924), rural dwellers (OR=1.500) and practitioners of other religions (OR=2.085) were more likely to sexually active than females, Adolescents, urban dwellers and Christians respectively. Multiple sexual partnership and inconsistent condom use among the sexually active participants were not predicted by any of the independent variables.
Conclusion: Risk behavior for HIV/AIDS is prevalent among university students in Nigeria. While personal religious tendencies did not predict sexual activity, an environment full of regular Christian religious activities seem to reduce risky sexual behavior. There is a need for more studies especially qualitative studies to explore the effect of religious factors on the practice of multiple sexual partnership and inconsistent condom use among sexually active students.

Persistent and Transient Inhibition of Seed Germination by Fractions of Methanol-Water Extract of Wheat Straw

L. S. Dias

Annual Research & Review in Biology, Page 3993-4003
DOI: 10.9734/ARRB/2014/12017

The objectives of this work were to investigate the effects of wheat straw constituents on total seed germination and on time needed for seed germination to start and to assess the usefulness of evaluating the recovery of germination to help guide the screening for a sequential search of bioactive natural phytochemicals. Dose-response bioassays of lettuce seed germination to increasing concentrations of six fractions of methanol-water extract were conducted and whenever inhibition of germination exceeded 90% non-germinated seeds were transferred to distilled water and recovery of germination investigated. Only the fractions essentially composed by neutral polar compounds and by acids failed to inhibit total germination. Fractions composed by strong acids, basic compounds and fatty acids plus steroids completely inhibited total germination at 5mg mL−1, the former also inhibiting germination by more than 90% at 1mg mL−1. In these three fractions the concentration necessary for 100% inhibition was estimated to range between 4.1 mg mL−1 and 4.4mg mL−1. Time needed for germination to start was always significantly increased even by fractions that failed to affect total germination. Basic compounds were the most effective in delaying the start of germination increasing it more than 4-fold at 2mg mL−1 from 1.0 to 4.3 days. When non-germinated seeds were transferred to distilled water persistence of complete inhibition was only found with strong acids, almost full persistence with basic compounds. Thus the consideration of recovery of germination makes possible a more informed choice of the fraction to select for further bioassay guided search for phytochemical with herbicide activity. The fraction is the one composed by strong acids, mainly phenolic acids, all of them identified, provided that persistent seed inhibition is desired and long term weed control through depletion of weed seed banks in soil is aimed.

Annual Research & Review in Biology, Page 4004-4022
DOI: 10.9734/ARRB/2014/11594

Aims: This research attempts to investigate the effect of a biologically mediated filtration technique {using the mycelia from two saprophytic filamentous fungi – Aspergillus flavus (A. flavus) and Aspergillus niger (A. niger), isolated from the soil} on the physicochemical indices of an Industrial (Brewery) effluent.
Study Design: The experiment was conducted in a Completely Randomized Design (CRD). In all cases, the value for each data was the mean from 3 replicates. Data were subjected to a one way analysis of variance – ANOVA, while the separation of the means (post Hoc Test) was done using the independent sample T-Test at 1% level of significance.
Place of Study: The Study was conducted at different Institutional Laboratories (such as the Federal Institute of Industrial Research, Oshodi; Environmental Biology Lab., Yaba College of Technology and Chemistry Lab., University of Lagos) in Lagos, Nigeria.
Methodology:
The effluent samples were analyzed for various physical parameters such as pH, temperature, turbidity, conductivity and Total Dissolved Solids and chemical parameters such as Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Phosphates, Sulphates, Chlorides, Hardness, Alkalinity and Nitrates using standard laboratory techniques and equipment.
Results: The results obtained from this work showed that both fungal species were able to bring about a significant (p≤0.01) improvement in most of the physicochemical parameters considered in this Brewery effluent when compared to the unfiltered (Control) effluent samples, as well as against approved benchmarks as provided by some statutory regulatory bodies in Nigeria such as the Lagos State Environmental Protection Agency (LASEPA) and now defunct Federal Environmental Protection Agency (FEPA).
Conclusion: The results from this study shows that A. niger and A. flavus (that were used in this experiment) has some promise at improving some important physicochemical indicators of a poorly treated brewery effluent.

DOI: 10.9734/ARRB/2014/10503

Aims: To examine the protective properties of vitamin C (vitC) and E (vitE) on DM induced nephrotoxicity in male guinea pigs.
Study Design: Twenty male rats were randomly grouped into four. “1” = Control, “2” = Vitamins (C & E) treated, “3” = Dimethoate (DM) treated and “4” = Vitamins treated plus DM treated.
Place and Duration of Study: Department of Biology, Ibb University, Ibb, Yemen between February 2011 and May 2011.
Methodology: Four animal groups were used, G1: received 1.0ml of distilled water and 1.0ml of olive oil, G2: received 200mg/kg b.w/day of vitamins (C & E), G3: was treated with 7mg/kg b.w/day DM and G4: was treated with 200mg/kg b.w/day of vitamins (C & E) plus 7mg/kg b.w/day DM. All the previous administrations were repeated daily for 28 days. At the end of the experiment, the animals were sacrificed and dissected. Blood and tissue samples were taken for biochemical, and light microscope investigations.
Results: DM administration resulted in a significant increase in the serum urea and creatinine levels and lipid peroxidation (LPO) level, while it caused significant decreases in the activities of catalase (CAT) and glutathione-S-transferase (GST). In contrast, co-administration of vitC and vitE to DM-treated animals restored most of these biochemical parameters to nearly normal levels. Also, DM induced histopathological changes in the kidneys of all treatment groups but these alterations were predominant in DM-treated group.
Conclusion: The results showed that co-treatment of vitE and vitC may protect the guinea pigs from DM-induced nephrotoxicity.

Aims: To screen fifty-six endophytic streptomyces isolates for anti-bacterial activity on two clinical strains of Acinetobacter baumannii (carbapenem sensitive and resistant).
Place and Duration of Study: Universiti Kebangsaan Malaysia; between May 2011 and February 2012.
Methods: In this study, 56 isolates of endophytic Streptomyces sp. and their extracts were screened for anti-bacterial activity against A. baumannii. The compound’s profile was obtained for determination of active metabolites
Results: The bioassay showed that 14 isolates namely “Strain Universiti Kebangsaan” (SUK) had anti-bacterial activity towards A. baumannii. Isolates SUK 31, SUK 56 and SUK 15 showed 100% inhibition, while SUK 8 and SUK 10 showed more than 50% inhibition. These 3 isolates proceeded with secondary metabolites extraction using ethyl acetate. Disc diffusion test showed the zone of inhibition towards sensitive and resistant strain of A. baumannii; by SUK 15 at 11 and 8 mm, while SUK 31 at 7 and 10 mm, respectively. Minimum inhibition concentration (MIC) and minimum bactericidal concentration (MBC) of SUK 8 were 1.0mg/mL and 4.0mg/mL, respectively. On the other hand, SUK 15, SUK 31 and SUK 56 had the same MIC and MBC values at 2.0mg/mL. Then again, there was no difference between the MIC and MBC values for both strains of A. baumannii. Analysis of profile extract components of one selected extract, SUK 8, showed that there was at least nine polar compounds that had been successfully separated using a Thin Layer Chromatography (TLC) technique.
Conclusion: Endophytic Streptomyces sp. exhibits an anti-bacterial activity against resistant and sensitive strains of A.baumannii, thus might be a potential drug candidate.

DOI: 10.9734/ARRB/2014/11101

Aims: To optimize the process variables including: Lactobacillus acidophilus La-5, total starter (a mixture of mesophilic cheese starters (MCS) and thermophilic yoghurt starters (TYS), mesophilic cheese starter: thermophilic yoghurt starter (MCS:TYS) ratio and salt content in probiotic Iranian ultrafiltered soft cheese (IUSC).
Methodology: In order to choose the best probiotic cheese formula with the highest Lactobacillus acidophilus La-5count, a total of eight samples with 20% total solids were produced using a small scale ultrafiltration system. Probiotic bacteria of Lactobacillus acidophilus La-5(0.1 and 0.3 %), total starters (1 and 2%), MCS: TYS ratio (8:2 and 7:3) and salt (NaCl) concentration (1 and 2%)by the help of Taguchi design were inoculated into cheeses and the viable cell counts of Lactobacillus acidophilus La-5enumeratedwithin 45 d of shelf lifeat5ºC, as well the multiple effects of process variables on probiotic count and colony morphologies of probiotic and starters evaluated.
Results: The most suitable conditions for the highest Lactobacillus acidophilus La-5 stability were addition of 0.1% w/w Lactobacillus acidophilus La-5, 1% v/w total starter, MCS:TYS ratio of 8:2 and 1 % w/w salt content. The lowest and highest viable cell count of probiotic Lactobacillus acidophilus La-5in IUSC ranged from 6.41 to 7.92 CFU.g-1, respectively. The acidified (pH 5.2) MRS agar medium used for the differentiation of the colony morphology of Lactobacillus bulgaricus and Lactobacillus acidophilus La-5, anaerobically. In all of the cheeses except for cheese 3 and 6 which the La-5 survived to 6.95 and 6.41 log orders, respectively, Lactobacillus acidophilus La-5cell count survived to over107 CFU.g-1, when all the cheeses had the small amount of acetic acid taste with a creamy and soft texture. The MCS:TYS ratio of 8:2 and 0.1% initial dosage of Lactobacillus acidophilus La-5(PË‚0.05) affected the probiotic stability of Lactobacillus acidophilus La-5 in IUSC during shelf life, however the salt content (1 and 2%) and total starter (1 and 2%) did not significantly influence the Lactobacillus acidophilus La-5viability.
Conclusion: This study showed that Iranian ultrafiltered soft cheese has a probiotic potential to have 107 CFU.g-1 viable cell count of Lactobacillus acidophilus La-5 strain, when process variables optimized and this progress will contribute to develop a healthier foods.

Annual Research & Review in Biology, Page 4104-4114
DOI: 10.9734/ARRB/2014/12006

Background: The industry of companion animal has been growing steadily in Korea. However, alongside this rapid growth, insufficient knowledge and immature civic awareness of the responsibilities of companion animal ownership has resulted in an increase in the number of stray animals.
Aim: The aim of this study was to form a strategy for reducing the number of stray dogs and returning the existing stray dogs to human homes in the community by comparing the difference of behavioral characteristics between stray dogs and house dogs.
Methodology: A total of 36 house dogs (HD) and stray dogs (SD) were enrolled in the study. The frequencies of and differences in aggressive, anxious, fearful, and friendly behaviors were analyzed. Various stimuli were used in five sections (section 1: appearance of a human; section 2: direct tough by a human; section 3: relationship with a dog; section 4: relationship with a human; section 5: extreme stimulation arousing fear). The dogs’ responses were categorized according to the aforementioned classes of behavior.
Results: There was no difference between HD and SD with regard to total frequency and average frequency of aggressive responses. The average frequency of trembling, panting, roaming, and total anxious behaviors was also high in sections 1 to 5 (P=.05). The frequency of fearful behavior was 2.4 to 15 times greater in SD than HD. In sections 1, 2, 4, and 5 (P=.01), the average frequency of submissive behaviors such as ears back, tail tucked in, low posture, sitting, and total fearfulness was significantly high (P=.01). Finally, the total frequency of friendly behaviors was similar in SD and HD; the average frequency in sections 4 and 5 (P=.05) was significantly greater for SD than HD.
Conclusions: The aggressive, fearful, anxious, and friendly reactions of stray dogs are relative to conditions in their environment. Stray dogs can be adopted as companion animals if their hygiene and health are cared for and if relaxation measures are implemented.

Annual Research & Review in Biology, Page 4137-4151
DOI: 10.9734/ARRB/2014/6492

Cranberries are small, dark red fruits that are widely consumed as juice. Nonalcoholic steatohepatitis (NASH) is a condition that may progress to end-stage liver disease. Rats were classified into four groups as follows: normal control group, NASH rats fed high fat diet, nonalcoholic steatohepatitic rats fed high fat diet and received lyophilized powdered cranberry suspended in 0.5% CMC, group fed basal diet and received lyophilized powdered cranberry suspended in 0.5% carboxymethyl cellulose CMC. The model of NASH rats elicited significant increase in serum lipid parameters: total cholesterol, total lipids, tricylglycerols and phospholipids, liver antioxidant enzyme activities with concomitant significant elevations in liver enzymes and glucose-6-phosphate dehydrogenase, in association with a reduction in reduced glutathione, glutathione peroxidase, serum total protein and direct and total bilirubin. Administration of cranberry to NASH rats produced significant increases in tested antioxidant enzyme activities, G6PD and serum total protein, direct and total bilirubin concomitant with significant decreases in the levels of serum lipids as well as liver enzymes AST, ALT, ALP, GST and ɣ-GT. In addition, it was noted that NASH rats exhibited a degree of DNA fragmentation; however, oral administration of cranberry extract partially inhibited the DNA fragmentation.

Jaouida Haouari-Abderrahim, Nassima Rehimi

Annual Research & Review in Biology, Page 4152-4165
DOI: 10.9734/ARRB/2014/11366

Aims: Insect growth regulators (IGRs) offer alternatives to conventional chemical larvicides that pose problem of resistance and environmental safety. However, only a limited number of IGRs have been approved for use in mosquito control. The present investigation was to evaluate the insecticidal activity of a non-steroidal ecdysteroid agonist, methoxyfenozide (RH-2485), against last-instar larvae of Culiseta morsitans (Culicidae: Diptera) under the laboratory conditions, and its effect on fecundity and fertility of females.
Methodology: Based on preliminary bioassays, five concentrations ranging from 0.012 to 0.072mg/L were tested. The larvicidal test was made according to the World Health Organization (WHO) protocol standard by exposing newly ecdysed fourth- instar larvae for 24h. CL50 value of methoxyfenozide value was determined by probit analysis.
Results: The insecticidal activity of methoxyfenozide result in a dose- dependent reduction in adult emergence. In addition, larval mortality was relatively important compared with the mortality recorded for the other following developmental stages. The larval mortality varies between 16.84±3.89 % and 66.24±3.50% for 0.012 mg/L and 0.072 mg/L, respectively, and LC50 value was 0.059mg/L. The ecdysteroidal activity of this compound caused premature induction of larval moulting and incomplete pupation. Also, the different types of morphogenetic aberrations in the larva, pupa and adult after exposure to methoxyfenozide are illustrated (larval-pupal and pupal-adult). Moreover, the tested compound greatly affected the reproductive parameters of surviving females derived from larval treatment. Methoxyfenozide caused a significant reduction of fecundity and fertility (P<0,001). Also, no egg laying has been recorded with the higher concentration 0.072 mg/L, which produced 100% of sterility.
Conclusion: Methoxyfenozide is an efficient insect growth regulator for controlling mosquito populations. This compound may prove to be an effective larvicide for treatment of mosquito, to decrease the frequency of pathogen transmission to humans and animals.

Imidacloprid and Methomyl are systemic insecticides used widely for controlling insects infesting crops grown in greenhouses. The experiment was conducted on tomato (Hassawi, Local Varity in Eastern part of Saudi Arabia) to study the phytotoxicity effect of the tested insecticides at various application rates. Imidacloprid was tested at (25, 50, 100, and 150 active ingredient (a.i) g/100L water), and Methomylat (15, 35, 50 and 70g a.i/100L). Both insecticides were shown to have negative effect on the growth of old and new parts (stem, leave and shoot) of tomato variety used for the experiment. The symptoms of leaf chlorosis of the old leaves and distorted growth and marginal necrosis of newer leaves were developed after 3 days of application with the highest rate for both insecticide experiments. When application at the lower rate, the phytotoxicity symptom was developed within the second week of application. The size of the new shoot was affected by high rate of application for both Imidacloprid and Methomyl and that was reflected in the reduction of the weight of dried shoot. In case of old leaf, despite the significant differences between the treatment and the reduction in dry weight in correlation with application rates were small. However, the lowest application rates of both tested insecticides showeda positive stimulation in the new growth that emerged after treatments, even though the lowest rate at (25g a.i/100L) of Imidacloprid caused some phytotoxicity symptoms by the end of the experiment. The results indicated the higher phytotoxicity of Imidacloprid than Methomyland the higher application rate had a significantly higher phytotoxicity effect on tested tomato plant than the lower application rate.

DOI: 10.9734/ARRB/2014/11847

The aim of this study was to evaluate the initial salinity and the type and amount of salt evacuated from soils of palomas, san luispotosí in a leaching process. These soils present primary and secondary salinization problems, induced by irrigation which affects their productive capacity. The study was conducted in a greenhouse and in the soils laboratory of the graduate college, from april to august 2010. Leaching of salts was done in soil columns that were applied with three soil-water extraction ratios, namely, 1≈0.2-0.6, 1:5 and 1:10, and the normal rates of leaching Qa/Qπ =0 ,1.5 AND 3.0, where: qa is the volume of water at which a soil reaches its saturation capacity, plus another equal volume, and so on. Qπ is the volume of water needed to make the soil reach its saturation capacity. This rate corresponds to volumes of water applied under field conditions of 1971.72 m3 ha-1, 2,957.58m3 ha-1, and 5915.16m3 ha-1, respectively. The initial salinity of each ratio was 69.03 mgha-1, 153.59mg ha-1 and 201.37mg ha-1. The higher extraction ratio and rate of leaching applied, the higher the amount of soluble salts leached, and the lower the average residual salinity of 0-50 cm soil layer. At zero leaching level no leachate was obtained. The extraction ratio 1:10 and the rate of leaching g Qa/Qπ =3.0, was significantly (p=0.05) outstanding. Under these conditions appreciable amount of salts were leached off the topsoil, especially nacl and na2so4 . The residual salinity of the 30 cm soil layer was 1.68 g salt 100 g-1 of soil (109.48 mg ha-1). This indicates desalination.

Aims: To assess the effect of clidinium-C on H. pylori eradication with a triple therapy including omeprazole, clarithromycin and amoxicillin (OCA) in patients with peptic ulcer disease (PUD). Also, to investigate the efficacy and safety of clidinium-C in prevention of drugs' side effects.
Study Design: Prospective double-blinded randomized clinical trial study.
Place and Duration of Study: Department of Internal Medicine, Golestan University of Medical Sciences, from March 2011 to November 2012.
Methodology: A total of 200 histopathologically proven H. pylori positive patients with PUD enrolled in this study were randomly assigned to participate in two groups: Group A: a 14-day OCA triple therapy with 20 mg omeprazole bid, 1000 mg amoxicillin bid and 500 mg clarithromycin bid; Group B: a 14-day clidinium-C bid plus OCA triple therapy. Subjects were asked to report any side effects of therapy during the treatment period. A13C-urea breath test was performed for eradication assessment 6 weeks after completion of the treatment.
Results: Totally 184 of 200 patients (90 in group A and 94 in group B) could continue the treatment protocols. H. pylori eradication was achieved in 71.1% in Group A (OCA without clidinium-C) and in 72.3% in Group B (OCA with clidinium-C), (p=0.73). The frequencies of abdominal pain and stool abnormality, among the side effects recorded during the therapy period, were significantly lower in group B (OCA with clidinium-C) than in group A (p=0.01 and p=0.001, respectively).
Conclusion: Addition of clidinium-C to OCA triple therapy does not increase the H. pylori eradication rates; however, it significantly decreases the frequency of abdominal pain and stool abnormality. This suggests a possibility that the addition of clidinium-C might be an option for increasing the patient's compliance.

Annual Research & Review in Biology, Page 4232-4245
DOI: 10.9734/ARRB/2014/11697

Aims: We characterized the responses of non-toxic seedlings of Jatropha curcas L. to variation in seed weight and substrate during their germination and growth.
Study Design: Two analytical experiments using a randomized controlled trial approach were applied to consider the effects of seed weight and substrate.
Place and Duration of Study: Non-toxic seeds from the east coast of Mexico were selected during two consecutive years and their seedlings were studied during one month after emergence.
Methodology: The seeds were grouped into different weight categories (400-499 - 800-899 mg). The substrates evaluated were sandy, sugarcane compost and a mix of sandy and sugarcane compost (sandy-compost, 2:1). While sandy substrate was poor in organic matter (OM), sugarcane compost was rich in OM. Germination, survival rate and mean germination time (MGT) were evaluated by seed weight category and substrate. We measured stem length, root collar diameter, number of leaves and leaf area every week, and at the end of the experiments total dry biomass was recorded.
Results: The heaviest seeds had higher germination rates (86.3%±7.1%) compared to the lightest seeds (69.9%±12.2%) in all substrates. Survival rate was 10% lower for the lightest seeds in sandy-compost and for the heaviest seeds in compost. MGT was not significantly different between seed weight categories or substrates (P=.32). Heavier seeds produced bigger seedlings in terms of stem length, root collar diameter, number of leaves, root length, and total dry mass in sandy-compost(P<.05). However, when substrates were compared, the substrate effect was larger than the effects from seed weight, with the largest seedlings found in compost (P<.05), regardless of seed weight.
Conclusion: Seed weight improved germination rates in sandy and sandy-compost substrates. Compost increased seedling growth regardless of seed weight.

DOI: 10.9734/ARRB/2014/11936

Climatic and technical factors influence tomato (Solanum lycopersicum L.) production in hydroponics and greenhouse, but there is not much research on management of red volcanic rock as substratum, as well as on water and nutrient solution. Therefore, the effect of the concentration of nutrient solution, irrigation frequency and the volume of substratum on growth, dry matter and fruit production was evaluated, and the economical impact was compared according to costs and yield. During 2007 and 2008, in the Experimental Field of the Universidad Autónoma Chapingo, Chapingo Mexico, concentrations of nutrient solution (100, 75, and 50%), irrigation frequency d-1 (1, 4, 7, and 10), and volumes of substratum plant-1 (5, 10, and 15L) were assessed in a completely randomized block design in a factorial treatment arrangement replicated three times. The results showed significant differences (P<0.05) between years, concentrations of nutrient solution, irrigation frequency, and volumes of substratum in growth and yield of dry matter and fruit. In 2008, there was major growth and yield of dry matter and fruit, compared to 2007. Nutrient solution at 75% diminished the fruit yield by 4.8% compared to 100%. With 7 irrigations d-1, stem thickness was reduced by 2.1, 1.8, and 1.7%, and the index of leaf area, and fruit yield, respectively, was compared to ten irrigations d-1. There were no differences between 10 and 15L in fruit yield. It is concluded that it is convenient to utilize the nutrient solution at 75% in seven irrigations d-1 and substratum volume of 10L for tomato production in hydroponics and greenhouse in order to obtain the highest profit (73.9%).

Aim: This study investigated the hypoglycemic, hematologic and hypolipidemic potentials of Mucuna pruriens ethanol leaf extract (MELE) in alloxan induced diabetic rats.
Study Design: Experimental Animal Model. The study was conducted in the Physiology Laboratory of the Department of Veterinary Physiology and Pharmacology, Michael Okpara University of Agriculture, Umudike, Nigeria between November, 2013 and February, 2014.
Methodology: Diabetic rats were divided into 4 groups of 7 animals each (groups 2-5). Group1 comprising of 7 normal rats received 0.2ml normal saline and served as the normal control group. Group 2 received no treatment and served as the diabetic control group. Group 3 was treated with a reference drug, Glibenclamide (5mg/kg) while groups 4 and 5 received 150 and 300mg/kg of MELE respectively. All treatments were done via the oral route and lasted for 21 days.
Results: Alldoses of MELE significantly (P<.05) lowered glucose levels in the diabetic rats with 300mg/kg lowering blood glucose from 311.80 ± 37.10 in diabetic rats to 91.30 ± 2.26 by the end of 21 days. The hypoglycemic effect of MELE compared favorably with that of Glibenclamide. Red blood cells (RBC) counts, packed cell volume (PCV),hemoglobin values were all significantly raised (P<.05) in treated rats, while the increased WBC value in diabetic rats was lowered. The levels of total cholesterol, triglycerides, low density lipoprotein cholesterol (LDL-C) and very low density lipoprotein cholesterol (VLDL-C) were significantly (P<.05) decreased in the diabetic treated rats with increase in the levels of high density lipoprotein cholesterol (HDL-C).
Conclusion: These results suggest that MELE contain active principles with hypoglycemic, hematologic and hypolipidemic properties and could be valuable in managing diabetic mellitus and correcting the hematological and lipid profile abnormalities associated with the pathophysiology of the disease.

This experiment was conducted to compare the performance and some blood biochemical parameters of Ross and Cobb broilers fed diets containing savory essential oils (SEO). Two hundred twenty four, 1-d-old broiler chickens (mean initial weight: 36.5±1g) of mixed sex (Ross-308 and Cobb) were randomly assigned to each of the 4 treatment groups, each with 4 replicate pens of 14 chicks. The experimental groups included two treatments for Ross strain – control (RC) and the group contain 500mg/Kg SEO (RS) - and two treatments for Cobb strain –control (CC) and the group contain 500mg/Kg SEO (CS). To measure some blood biochemical parameters at the age of 30 days, from each repetition, two broilers were selected and blood sampling was performed through a wing vein.As a result of this study fed essential oil in diet had not significant effect on feed intake, but DBWG (54.10 and 55.00 for RS and CS respectively) and FCR (1.8 and 1.75 for RS and CS respectively) improved significantly (P≤0.5). Broilers receiving SEO had a significantly (p≤0.05) lower cholesterol, HDL and glucose concentrations compared to control groups. In general, the results indicate that dietary inclusion of 500 mg/kg savory essential oils can improve performance and some blood biochemical parameters in Ross and Cobb broiler strains.

Amtul Jamil Sami, Madeeha Khalid, Saliah Bilal

Annual Research & Review in Biology, Page 4426-4444
DOI: 10.9734/ARRB/2014/7856

Aims: Oxya chinensis is a very serious paddy pest and causes major loss in rice crop. The objectives of the study were (1) Studying the molecular basis of plant biomass degradation by Oxya chinensis. (2) The role of Neem (Azadirachta indica) derived compounds, Azadirachtin and Saponins was also studied as enzyme inhibitors with special reference to biopesticides.
Place of Study: Institute of Biochemistry and Biotechnology, University of the Punjab, Lahore.
Methodology: Oxya chinensis insects were collected from local fields and dried. The dried insects were studied for the purification and characterization of cellulose hydrolyzing enzyme activity. Enzyme was purified using ion-exchange chromatography. Spectroscopic study was carried out to identify the signature pattern of the protein. The role of purified neem (Azadirachta indica) derived compounds Saponins and Azadirachtin was also studied as enzyme inhibitors with special reference to Biopesticides.
Results: Total soluble protein was isolated from salivary gland and gut and the presence of cellulase activity endo-1, 4-ß-glucanase (OcCel9) in each tissue was indicated. After purification both enzymes appeared at same position on zymogram, containing 2.0% carboxymethyl cellulose as substrate, after non-denaturing PAGE. The beta-1,4-β-glucanase (OcCel9) activity from the gut and salivary gland had the same Km values. The pH and temperature profiles of Oxya chinensis beta-1,4-glucanase indicated optimum pH at 3.0 and optimum temperature at 50ºC. SDS-PAGE analysis indicated that the enzyme has two subunits/isozymes of molecular mass 60 and 55 kDa respectively. The spectroscopic analysis of the isolated protein showed that it had homology with rice, 1, 4-beta-D-glucanase. An internal amino acid sequence of the rice enzyme (OcCel9) revealed that this enzyme belongs to glycosyl hydrolase family 9 (Glycosylhydrolases family 9 active sites signature 2). Neem, Azadirachtaindica derived saponins were able to inhibit OcCel9 on substrate agar plates.
Conclusion: OcCel9 was successfully purified and is a very active cellulose hydrolyzing enzyme and can be of significant technological importance. Moreover the enzyme can be studied as a potential target for producing novel biopesicides.

Annual Research & Review in Biology, Page 4459-4470
DOI: 10.9734/ARRB/2014/12113

Aim: The objective of the present work was to assess the ability of crude peroxidase from hairy roots of Armoracia rusticana (horseradish) to decolourise two model azo dyes: The mono-azo dye Methyl Orange (MO) and the di-azo dye Bismarck Brown (BB).
Study Design: The enzymatic decolourisation of aqueous solutions of the model dyes was performed by varying reaction parameters like pH of reaction mixture, crude enzyme concentration, dye concentration and hydrogen peroxide concentration; at ambient temperature (25±2ºC). The emphasis was on using a crude extract that showed high enzyme activity, despite being obtained by minimum processing, and virtually no purification.
Methodology: Hairy root cultures of A. rusticana were used as the source of crude peroxidase. The hairy root tissue was macerated using phosphate buffer (pH 5.8) and centrifuged. The clear supernatant was used as crude enzyme. The decolourisation of the dyes was assessed using spectrophotometric method. Appropriate controls to account for bleaching due to hydrogen peroxide were maintained. Decolourisation of MO and BB by the Fenton reaction was used as a positive control for decolourisation.
Results: The crude peroxidase extract can bring about up to 73% and 32% decolourisation of MO and BB respectively within a reaction time of two hours (2h).
Conclusion: The outcome of the present work can find application in the enzymatic treatment of wastewater containing azo dyes. This oxidative decolourisation method appears to be better suited to the decolourisation of mono-azo dyes.

Annual Research & Review in Biology, Page 4482-4501
DOI: 10.9734/ARRB/2014/12044

Malaria as among vector-borne diseases is reemerging in areas where control efforts were once effective and emerging in areas though free of the disease as a consequence of human migration and rapid growth of international traffic from malaria prevalent areas of the world to malaria free zone. In this paper we develop a mathematical model for the spread of Plasmodium knowlesi malaria from infected humans to mosquitoes. The stability analysis of the model is investigated rigorously. The model is extended to assess the impact of time dependent preventive (biological and chemical control) against the mosquitoes and treatment for infected humans. The existence of optimal control is established analytically by the use of optimal control theory. Numerical simulations of the problem, suggest that applying the three control measure can effectively reduce if not eliminate the spread of Plasmodium knowlesi malaria in a community.

DOI: 10.9734/ARRB/2014/10732

Aims: This study aims to contribute to the sustainable management of S. setigera, a native gum and multipurpose tree in Togo. Especially, it aims to: (i) Assess the diversity of woody species within S. setigera stands, and (ii) Analyze the distribution, abundance and structure of S. setigera trees, according to contrasting environmental factors and human activities within the different eco-floristic zones of Togo.
Place and Duration of Study: Fieldworks were done from 10 October to 15 December 2013 throughout Togo.
Methodology: Dendrometric and ecological data of Sterculia setigera stands were recorded in 350 plots. In each plot, total height and girth of all woody species with diameter at breast height (DBH) ≥ 10 cm were measured and all human activities were recorded. In addition, seedlings and suckers of S. setigera species (DBH < 10 cm) were counted. The spatial distribution analysis of the species was done using Geographic Information System (GIS).
Results: Ninety six (96) woody species distributed among 71 genera and 31 families were identified. The highest species richness were recorded in the eco-floristic zone I (82 species), followed by zone III and zone II (41 and 40 respectively). Within these zones, the most representative woody species apart from S. setigera are Vitellaria paradoxa and Parkia biglobosa. In contrast, the most represented woody species in zone V were Cussonia arborea and Odinaacida. Statistic tests showed a significant difference of S. setigera densities following eco-floristic zones (p=0.00); especially between zone I and zone V (30.45 stems/ha and 7.57 stems/ha respectively). The overall regeneration rate was weak with a total absence within zone V. This regeneration status could justify the relatively few small stems proportion described by the coefficient of skewness values (g>0). Green Index values (GI, nearest 0) showed a random distribution of the species. The main human activities threatening S. setigera stands were bushfire, woodcutting, pasture and agriculture. According to the level of human activities Fisher test showed a significant difference (p=0.00), particularly between zone I with highest activities level and zone V with lowest activities (mean, 2.62±1.12 and 1.07±0.26).
Conclusion: The species richness within S. setigera stands and the density of S. setigera decrease from north to south (respectively from eco-floristic zone I to V). Both density and regeneration of S. setigera were shaped by human activities and environmental factors. Weak regeneration highlights that the future existence of the species is jeopardized.

Maria Luís Queirós, Margarida Lima

Annual Research & Review in Biology, Page 3586-3614
DOI: 10.9734/ARRB/2014/10968

NK cell dysfunction is observed in a variety of physiological and pathological conditions and cytotoxic assays allow to evaluating in vitro the lytic activity of NK cells against tumors or transformed target cells. Since the earliest cytotoxic tests based on the direct visualization of effector/target cell conjugates and the use of trypan blue to exclude non-viable target cells using a light microscope, a variety of cytotoxic assays have been developed. The 51chromium release assay was the most widely used for a long time, although it has several significant drawbacks, the major disadvantage being the use of radioactive compounds. To overcome this problem, several non-radioactive methods have been described, but none is broadly accepted. Among them, flow cytometry has a potential for providing information about the ability of the NK cells to lyse their targets. We review the clinical conditions associated with NK cell dysfunction as well as the role of the NK cells in immunotherapy and describe the available assays for measuring the activity of NK-cells with emphasis on flow cytometry.

Excessive use of narcotic drugs, especially its effect on the central nervous system (CNS) development of the embryos, has given rise to numerous studies in this field. According to the previous studies, morphine consumption during pregnancy can cause a delay in normal development of placenta and embryo. Based on the studies conducted on pregnant mothers’ embryo most abnormalities caused by morphine consumption are related to normal development defects of the embryo’s (CNS). Drug consumption is one of the factors that involve in epigenetic modifications. Epigenetic bioenvironmental effects such as incompetent nutrition, maladies, infections, stressors and drugs consumption, are some of instances that affect safety and genesis of embryo’s (CNS). Survey of epigenetic changes role in normal genesis of embryo’s (CNS), is inclusive of world new researches. Identity of different factors of epigenetic modifications is effective in embryo’s (CNS) health. Changes induced by epigenetic factors can be moderated or reversed by controlling the epigenetic factors. Based on studies, major epigenetic modifications are relevant to DNA methylation and histone modifications. Most important way in prevention from maladies and malformations that result from epigenetic modifications is recognition of epigenetic factors. This paper is a review of the studies on morphine’s role in the abnormal development of different parts of an embryo’s nervous system .These abnormalities are mainly visible in opioid-dependent mothers and fetuses and include brain nuclei, brain ventricles, choroid plexus, cerebellum, spinal cord, and vision, olfaction , taste deficiencies and epigenetic.

Involvement of Salicylic Acid in Sulfur Induced Salinity Tolerance: A Role of Glutathione

Rahat Nazar, Shahid Umar, Nafees A. Khan

Annual Research & Review in Biology, Page 3875-3893
DOI: 10.9734/ARRB/2014/11773

Plants are severely affected by salinity due to its high magnitude of adverse impacts and worldwide distribution. Among various strategies, nutrient management may be an important aspect in alleviating stress under varied environmental conditions. The uptake and assimilation of sulfur plays an inevitable and imperative role in determining plant growth and development and is a fundamental part of several important compounds, such as glutathione, co-enzymes, vitamins, phytohormones and reduced sulfur compounds that decipher growth and vigour of plants under optimal and stressful environments. Assimilatory sulfate reduction may induce salt tolerance by coordinating various physiological processes and molecular mechanisms which are likely to be induced by phytohormones. Among phytohormones salicylic acid (SA) could provide tolerance against salinity stress by enhancing physiological processes and can improve salinity tolerance by its effect on sulfur assimilation pathway as biochemically or molecular mechanisms. The present review critically evaluates the recent studies on the modulation of sulfur assimilation and gives an insight into the role of glutathione to maintain redox state and their cumulative significance in plants’ tolerance to salinity by SA in inducing various physiological responses in plants under salinity stress.

In clinic practice the reduction of cerebral blood flow in particular zones of the brain as brainstem can cause early cerebral damage then, ischemia and posterior reperfusion induce an inflammatory response leading to further cellular death. Indeed, inflammatory cells may release deleterious compounds or cytokines that exacerbate oxidative damage to metabolically compromised neurons, and similar mechanisms may operate in the pathophysiology of neurodegenerative diseases in which vascular factors, inflammation and oxidative stress are implicated. In the present work, the issue referent to mechanisms of pro-oxidants in inflammatory processes, and its relation with common pathogenesis and clinical manifestations are analyzed in detailed and updated form.

Ana Coelho, Viviana Macho, Manuel Ferreira, Eunice Carrilho

Annual Research & Review in Biology, Page 3970-3979
DOI: 10.9734/ARRB/2014/12257

Aim: To review the scientific principles of the treatment of white spot lesions with the resin infiltration technique and to discuss its application and limitations.
Methodology: A PubMed database research was conducted and limited to articles published in English between the years of 2008 and 2013. Twenty-six articles were selected out of 48.
Discussion: The resin infiltration procedure is a promising minimally invasive dentistry technique. Resin infiltration produces a positive effect on aesthetics, preserves tooth structure, delays or even eliminates the need for a restorative treatment and eliminates the risk of post-operative sensitivity and pulp inflammation. Although it has recently been developed, the results are very satisfactory. However, investigation is still needed (particularly with longer follow-ups and larger samples) as well as the development of specific and simplified protocols.

Taxonomic information provides the base line for most of the studies in biological sciences. Most of taxonomic information based on phenotypic characteristics of plants. As phenotypic markers are under the influence of environment, therefore it may leads toward the taxonomic confusion. Therefore, present study was carried out to determine the effect of environment on types of stomata, number, size, and stomata patterning which is very useful feature in taxonomy. In the present study thirty arboreal species of dicot flora (from tropical and subtropical regions) belonging to eight orders and fifteen families are evaluated by using systematic tool i.e. stomatal pattering. Stomata play a vital role in gas exchange of dicot plants. Within dicot flora, eight shapes of stomata are observed (anomocytic, anomotetracytic, actinocytic, amphianisocytic, brachyparacytic, anisocytic, amphicyclocytic and staurocytic). In leaves, the pattern of stomatal distribution is highly variable between arboreal species of dicot but is regulated by a mechanism of one cell spacing between stomata. Epidermal anatomical marker showed the different mode of stomata patterning. Hence, this differential marker can be utilized to differentiate taxonomically complicated species.

We review the use of diatoms in monitoring and assessment of river health in the world. First, we summarize the use of diatoms as indicators of nutritional status, acidification, and organic and metal pollution. We then examine some problems that have been associated with diatoms and indices that were used in different regions around the world: 1) incomplete taxonomy; 2) effects of natural geographic differences on diatom distributions (e.g., climate, lithology); 3) effects of natural site differences on diatom distribution and abundance (e.g., substrate, depth, chemistry); 4) differences in sampling, sample processing, and analytical methods; and 5) difficulties in finding minimally disturbed reference sites. Based on these problems, we present the different selections and the research progress of diatoms and indices used in monitoring and assessing river health around the world including the Americas, Europe, Africa, Asia, and Australia. We recommend that future studies and uses of diatoms focus on the following aspects: 1) improve the classification and identification of diatoms; 2) increase the use of diatom predictive indices to monitor and assess water quality; 3) develop global standard methods for sampling diatoms in streams, rivers, and lakes; and 4) apply hind-casting predictive models.

Enterococcus faecalis possesses the unique properties such as production of serine protease and specific gene Ace, which aid in binding to extra cellular matrix protein like collagen, aggregation substances that help E. faecalis adhesion to recipient bacteria; helps to form biofilms through surface adhesion, which in turn resist alkalinity of calcium hydroxide in the medicated canal. The production of lipoteichoic acid by E. faecalis enables binding to PNM cell, erythrocytes, and platelets, and lysis of cell in vitro and in vivo. It can resist the high temperature of 60ºC for 30 minutes and can grow at 10–45ºC in a pH of 9.6, and is the most frequently isolated micro-organism from root-filled teeth. E. faecalis can penetrate up to 140 to 160 µm deep into root dentin and root cementum beyond minor constriction in root-filled teeth. The aim of this article is to understand the role of E. faecalis beyond minor constriction and its role in causing persisting infection. It was found that the virulent factors and ability of E. faecalis to penetrate deep into root dentin and root cementum beyond minor constriction and ability to adapt to environment in adverse conditions are the possible causes for persisting infection in root-filled teeth.

The improvement in the understanding of cancer immunology did not lead to a successful immunotherapeutic strategy. Cancer immunotherapy faces different obstacles including low immunogenicity, production of immunosuppressive agents, and the peripheral tolerance which is used by cancer cells to avoid recognition and destruction by effective cells in the immune system. The establishment and maintenance of immune tolerance is a result of a contribution of various immune cells. This review discusses the role of immune cells that support tumor growth and suggests some immunotherapeutic strategies that may increase tumor immunogenicity and improve immunotherapy. However, a careful preclinical and clinical evaluation is essential before considering these strategies as therapeutic options.

DOI: 10.9734/ARRB/2014/12264

The focus on herbal products for medicinal proposes has increased during the past decade. Papaver rhoaes L. (PR), commonly known as corn poppy, belongs to the Papaveracea family is used in southwestern Asia for some medicinal proposes. Modern pharmacology revealed that its extract contains several alkaloids such as rhoeadine, rhoeadic acid, papaveric acid, rhoeagenine, and anthocyanins. Studies in animal models have shown that PR extract can reduce morphine-induced place preference, sensitization, locomotor activity, and locomotor and pain tolerance. Furthermore, it has been shown that the extract also reduces stress-induced alterations in plasma corticosterone levels and induces analgesic and anti-inflammatory effects in mice. None clinical trial study finds for this plant. In conclusion, despite of lack in clinical trial studies, the existing evidence suggests that the PR extract possess medicinal properties and may be used as a therapeutic for drug addiction and pain and stress management.

DOI: 10.9734/ARRB/2014/11484

Aims: The aim of the present study was to qualify and quantify the toxicological researches in the Middle East countries. Comparisons were made with the rest of the world.
Place and Duration of Study: The current study was carried out during the 1st of January to the 31st of December, 2013 in the department of toxicology and pharmacology, Jundishapur University of Medical Sciences, Ahvaz, Iran.
Study design: This bibliometric study evaluates quantities and qualities of publications on toxicological researches in SJR for over 16 years (1996-2012).
Methodology: Strategy of the research was based on the keyword "toxicology". Neither language nor document type restrictions were considered. Data were extracted, tabulated, and compared to identify the ranks as well as trends. Additionally, comparisons were performed on the basis of ‘total number of documents’, ‘total number of citations’, ‘citations per documents’, “citable documents”, “cite-self cite per documents” , “H-index” , “self citation”, and international collaboration.
Results: Results showed an increase in the number of publications and citable documents in the Middle East. Northern America, Western Europe, and Asiatic regions led quantitative and qualitative indicators like H-index and citation. Comparisons among the Middle East countries showed Turkey, Iran, Egypt, Saudi Arabia, and United Arab Emirates are the most productive countries, respectively. Although the Middle East productions of scientific publications on toxicology are neither qualitatively nor quantitatively comparable with other regions, the trend has changed quantitatively during 1996-2012. As a result, the Middle East countries have to support their scientific institutes to increase the quantities and qualities of toxicological publications.

Inborn errors of amino acid metabolism include inherited biochemical disorders in which a specific enzyme defect interferes with the normal metabolism of protein. In these disorders as a result of diminished or absent enzyme activity, certain compounds accumulate in the body to toxic levels. Metabolic disturbances can lead to severe cognitive impairment and even death. Phenylketonuria, is the most common amino acid disorder. Dietary restriction prevent the accumulation of a substrate to toxic levels to a certain extend but application of biotechnological methods could provided more promising tools. The main topics discussed are: removal of phenylalanine by activated carbon, by tailored enzymatic hydrolyses of cheese whey, by modified corn cobs as adsorbents and by using enzymatic membrane reactor.
