The success of surgical endodontics depends on accurate diagnosis and treatment planning. Radiographic examination continues to be an essential part of diagnosis and management. Conventional periapical radiography creates superimposition and distortion. Low magnification provides inadequate diagnostic information and leads to compromised treatment. Cone Beam Computed Tomography (CBCT) overcomes the limitations by generating a 3-D image. In addition, CBCT provides a small field of view at low doses with sufficient spatial resolution and gives fine details of the surgical site. The present paper describes successful management of specific cases and how diagnosis and treatment planning has improved with the use of CBCT technology when compared to conventional radiography. In case 1 palatogingival groove was viewed through the axial and sagittal section of CBCT which was not seen in conventional radiograph. In case 2 non odontogenic cyst was evaluated through CBCT which showed that the pathology was not confined with the maxillary central incisor and in case 3 impacted root was detected in CBCT image.

Production and quality of citrus fruits depend largely on scion/rootstock compatibility. In order to find suitable combinations able to solve productivity problems of citrus at local scale, the performance of ‘Valencia late’ sweet orange (Citrus sinensis) on 14 rootstocks was studied under field conditions in the Gharb region (northwestern Morocco) through a field experiment. Total cumulative yield over five years of production was highest on Citrumelo 4475 (11) and PT B6 Z13 (5) compared to the other rootstocks. In terms of productivity, Citrumelo 4475 (11), Citrus volkameriana (25), Citrus macrophylla (24) and the Sunki mandarin x PT (16) and Sunki mandarin x PT (39) hybrids were the most efficient. Furthermore, this study revealed that the use of some rootstocks improved significantly juice content of Valencia late fruits. These included Citrus volkameriana (25), PT B6 CZ 24 (3), PT B6 CZ 13 (5), Cleopatra mandarin x CC (30), Sunki mandarin x PT (16), Citrumelo 4475 (11) and Citrumelo 1452 (41). Concerning juice quality, the study has identified rootstocks that enhanced both acid and sugar contents, namely Carrizo citrange (7), Sunki mandarin x PT (17), Citrumelo 1452 (41), Citrumelo 4475 (11), Sunki mandarin x PT (17), Sunki mandarin x PT (16) and PT B6 CZ 24 (3).

Aims: This study aimed to evaluate chemical quality and fatty acid profile of traditional butter samples in Zanjan, Iran.

Study Design: Quantitative determination of chemical quality and fatty acid profiles of 30 samples of Traditional cows’ butter was carried out from market of Zanjan, Iran.   

Place and Duration of Study: Department of food safety and hygiene in school of Health, Zanjan University of Medical Sciences, Zanjan, Iran during spring in 2016.

Methodology: Chemical quality of butter samples was evaluated using measurement of moisture, peroxide value, saponification value and Iodine value according to standard protocols of the national institute of standards and industrial research of Iran, No. 8381-1, 4179, 10501 and 4888, respectively. Determination of fatty acid composition was in accordance with Iranian national standard No. 8818 (Preparation of fatty acid methyl esters) and 8819 (measuring of fatty acids) using a gas chromatography.

Results: Total moisture of all samples varied from 17.3% to 22.3%. Peroxide value of butter samples changed from 0.4-3.2 mEq/ kg. Average saponification value and Iodine value of the samples were 178.02±14.8 mg/g and 27±1.41%, respectively. The results of Fatty acid profile showed the total of short-chain fatty acid contents of butter samples varied from 0.38% to 1.14%, while medium-chain fatty acid levels ranged from 0.44% to 12.88%. Minimum and maximum contents of long-chain fatty acids of butter samples were 0.52% and 29.39%.

Conclusion: The present study, investigation of chemical quality and fatty acids profile showed that moisture content of all butter samples were higher than standard range and both palmitic acid and oleic acid were most predominant saturated and monounsaturated fatty acids, respectively. Chemical quality of butter samples can be protected by control of hygienic conditions in production process and keeping the cold chain until the consumption.

Background and Aim: Brucellosis is a zoonosis of worldwide public health and economic importance, affects mainly domestic animals and it may be the genus Brucella, transmitted to humans by contact with infected domestic animals. Brucellosis control and eradication require serological tests and vaccines. The purpose of present study was to detection of Brucella spp. infection in human blood samples by molecular method.

Methodology: The number of 200 blood specimens (including 118 males and 82 females, between 10 and 70 years of age) were obtained from companion humans referred to the Polyclinic Laboratory in Kashani hospital, Shahrekord. Total DNA was extracted and the region encoded the omp2a gene was amplified by PCR using specific primers.

Results: 12 out of the 200 serum samples (6%) were found to be positive for Brucella spp (193 bp). 7 positive samples were in male group and 5 positive samples were in female group.

Conclusion: PCR was considered as the golden test for diagnosis of brucellosis. The eradication of brucellosis as a major zoonotic problem in animals is a necessary step to control the disease in human.

The people of Bangladesh are dependent mostly on groundwater for their drinking purpose. But due to salinity and arsenic problem in ground water, alternative techniques such as pond sand filters (PSF), rainwater harvesting system (RWH) and protected pond water (PW) are widely been used in saline and arsenic affected areas of southwestern coastal regions of Bangladesh. This study was conducted to assess the performance and functionality of these technologies at Chalna Paurashova in Dacop subdistrict of Khulna district. For this purpose, a questionnaire survey was carried out to get opinion on existing PSFs, RWHs and PWs. A total of 80 respondents were randomly selected and interviewed. Among them 35 samples from PSF users, 20 samples were from RWHs users and 25 samples were from PW users were collected. For laboratory analysis a total of 12 water samples from PSF, RWH and PW were also collected from different parts of Chalna union (Local administrative unit). Laboratory result shows that various chemical parameters have been exceeded the permissible limits of World Health Organization (WHO) and Bangladesh standards at some sampling points. Survey results show that, RWHs is well maintained and its water is safer than PSF. But this technology is not functional at community level and cannot supply water round the year. About 52.66% RWHs users face water unavailability for about two to five months and that time they have to depend on other water sources. On the other hand, 92.56% PSF users says that, water is available for round the year and PSF technology has more capability to solve year round water crisis at that rural community level. People in this area also said that lower cost of RWHs and good maintenance of PW also helps minimize water crisis. Their opinion similarly shows that these technologies are socially accepted. This study could be helpful for developing policy makers to detect better path of alternative water resource for coastal people who are facing scarcity of drinking water.
