Coronavirus affects human lung tissues. Covid-19 should be infection of the lungs, the virus infects alveolar cells resulting in reduced production of pulmonary surfactant. Pulmonary surfactant is a complex of lipids and proteins that line the alveolar epithelial surface and stabilize it during respiration. The surfactant helps to reduce the surface tension on alveoli. The surface-active components of the alveoli are a complex mixture of specific lipids, proteins and carbohydrates, which is produced in the lungs by type II alveolar epithelial cells. As a result, the lungs continue to collapse, reducing its own volume, but the collapse is prevented by the muscles of inspiration, which instead increase its volume. Covid-19 allows the surfactant to maintain the correct amount of surfactant during the acute phase of infection during lung infection and allows time to resume and allow individual surfactant production for type II cells. Surfactant degradation or inactivation may contribute to increased susceptibility to pneumonia and increased susceptibility to infection. Surfactant deficiency in patients with acute respiratory syndrome in adults and surfactant administration may be a useful therapy against Covid-19.</p> Sony Ahmed, Md. Shamim Akter, Kallol Roy, Md.

The controls had tested negative to Hepatitis B Virus, Human immunodeficiency Virus and hepatitis C virus infections. Whole blood samples were collected from the Human immunodeficiency Virus positive and control samples. Haemoglobin concentration was analysed using the Orphěe Mythic 22 automated analyzer. Serum samples collected from all 86 subjects were used to assay Interleukin 3 using the Enzyme Linked Immunosorbent assay based Finetest human interleukin 3 kit.</p> <p><strong>Results: </strong>A highly significant decrease in interleukin 3 levels was observed in Hepatitis B Virus and Human immunodeficiency virus positive subjects when compared with the apparently healthy control subjects, (P = 0.000 &lt; 0.05). Average hemoglobin levels were also lower in the Human immunodeficiency virus subjects compared with the controls.</p> <p><strong>Conclusion:</strong> A reduction of the interleukin 3 may be part of the synergistic factors responsible for the anaemia usually seen in the viral infections.</p> Chinenye E.

The main objectives of the present investigation were to: (i) identify the drought and low N tolerant genotypes, (ii) estimate the superiority of tolerant to sensitive genotypes and (iii) assess the differential response of maize genotypes to elevated levels of nitrogen. Maize genotypes were evaluated in 2016 and 2017 seasons under three N rates: high; 285.6, medium; 166.6 and low; 47.6 kg N/ha and two irrigation regimes: well-watered (WW) and water stressed (WS) at flowering. A split-split-plot design with three replications was used. Main plots were allotted to irrigation regimes, sub-plots to N rates and sub-sub-plots to genotypes. The tolerant (T) and sensitive (S) genotypes were identified under each stress. Grain yield/plant (GYPP) of T genotypes was significantly (P≤ 0.01) superior to as compared to S genotypes by 109.5%, 39.6% and 141.9% under Low-N, drought, and drought combined with low-N, respectively. Superiority of T over S genotypes in GYPP was associated with significant (P≤ 0.01) superiority in ears/plant (11.5, 13.15 and 11.99%), 100-kernel weight (38.65, 30.46 and 30.99%), kernels/row (22.81, 11.28 and 20.07%), Nitrogen use efficiency (109.49, 39.62 and 141.89%) and shortening in anthesis-silking interval (-44.56, -29.58 and -29.08%), under the three environments, respectively. A significant linear response on elevated levels of nitrogen was shown by 13 genotypes, but a quadratic response was shown by six genotypes. The present study suggested that further investigation should be conducted to identify the optimum N fertilization rate for each newly developed variety of maize.</p> A. M. M. Al-Naggar, M. M.

Moench Accessions Based on Qualitative Characters https://journalarrb.com/index.php/ARRB/article/view/30234 <p><em>Sorghum bicolor</em> (L.) Moench is a member of Poaceae family with three agronomic types corresponds to their specific uses namely grain sorghum, sweet sorghum, and forage sorghum. Although sorghum in Indonesia is considered as under-utilized crop, but it has the potential as an alternative resource for staple food in diversification program to support food security. The potential of sorghum as alternative staple food is due to its high nutritional value, and the ability to grow well in marginal lands with maintaining good productivity. The objectives of this study were to assess the extent of morphological variability and to resolve taxonomic relationship of sorghum accessions from Java Island based on morphological characters. Twenty nine sorghum samples were collected from three provinces in Java, namely Central Java, Special Province of Yogyakarta, and East Java. Morphological data observed refers to Descriptors for Sorghum, generating 19 qualitative characters used in cluster analysis and principal component analysis. Cluster analysis resulted in the grouping of 29 accessions into three groups corresponding to the racial classification of sorghum. Results of principal component analysis showed that the main distinguishing characters between groups were inflorescence compactness and shape, glume coverage, presence or absence of awn, presence or absence of grain sub-coat, grain shape, and grain color. Analysis of correlation showed that there were very strong relationship between glume coverage and the presence of awn, and between the presence of grain sub-coat and grain color. Results of this study revealed that sorghum accessions cultivated on Java Island consisted of four races namely Bicolor, Guinea, Caudatum, and Kafir.</p> Ika Nugraheni Ari Martiwi, Laurentius Hartanto Nugroho, Budi Setiadi Daryono, Ratna Susandarini ##submission.copyrightStatement## https://journalarrb.com/index.php/ARRB/article/view/30234 Wed, 01 Jul 2020 00:00:00 +0000
