    Abstract: Hydrogen cyanide is a highly toxic volatile compound which interferes with the cellular respiration by inhibiting the cytochrome oxidase enzyme in mitochondria. Root area of crops were consisting several bacteria that may have beneficial aspects. The objective of this study was to investigate the qualitative capability of hydrogen cyanide productio...

    Abstract: Musk deer, as a small hornless group, are of great significance in the phylogenetic evolution of ruminants. Clarification of their evolutionary history has the potential to contribute to an understanding of the total phylogeny of both cervids and bovids. In this paper, based on a comprehensive review of the literature, an integrated rearrangement o... Show More

    Abstract: In order to facilitate reasoned scientific decisions on its management and conservation, genetic analysis of six populations of P. Africana sampled from six different geographical regions of Ethiopia was performed using Random Amplified Polymorphic DNA (RAPD) markers. Seventy six percent of the loci studied revealed polymorphisim for the whole data... Show More

    Abstract: Thalassemias are a group of recessively inherited genetic disorders mostly common in the Mediterranean, the equatorial and near equatorial regions of Africa and Asia. Large number of mutations cause abnormal globin gene expression and result in complete absence or reduction of globin chain synthesis which lead to thalassemia. β-thalassemia is the r... Show More

    Abstract: This study evaluated the tyrosinase-inhibition activities of three extracts; methanol, acetone and dichloromethane of Datura metel leaves. The bioactive components were extracted and then evaluated for their inhibitory effect in vitro on mushroom tyrosinase, using a colorimetric procedure. The Methanolic extract of the plant leaf had the highest in... Show More

    Abstract: The von Willebrand Factor (vWF) gene located on Chromosome 12 spans ~ 180 kilobases with 52 exons. Changes in the vWF gene could alter VWF biosynthesis, secretion, clearance, and adhesion activity. Single nucleotide polymorphisms (SNPs) in exons, 5′ regulatory region, and introns are also reported to influence levels of vWF in healthy subjects. Som... Show More

    Abstract: The present study was carried out to determine the heavy metals (Cd, Pb, Zn, Al, Cu, Ni, Fe, Mn, Cr, Co) in the muscles of 32 fish species for 3 seasons in Meghna River. The heavy metals were analyzed by Atomic Absorption Spectrophotometer. The estimated concentrations of all metals in the present study were lower than the limits permitted by FAO, ... Show More
