Abstract Background The matter of antimicrobial resistance evokes the urgency to explore alternatives antibiotics traditionally used for microbial infections. This study aimed elucidate mechanism action antibacterial effect Khaya senegalensis liable bacterial strains responsible diarrheal Results data collected indicate that tested ( Salmonella Typhimurium ATCC 14028, Escherichia coli 25922, Sh...

Region growing algorithm has successfully been used as a segmentation technique of digital images. The current study went one step further by utilizing the potential use of thresholding the region growing algorithm as features extraction technique. The proposed features extraction algorithm is called seeded region growing features extraction (SRGFE). This algorithm was used to extract four feat...

Background: ROS are free radicals that have a significant role in many of the sperm physiological processes. In the presence of polyunsaturated fatty acids such as sperm plasma membrane,ROS triggers a chain of chemical reactions called lipid peroxidation.The aim of this study was to determine and compare the concentration of MDA and NO in testicular extract of hyperprolactinemic adult male mice...

Genetic analysis of protein secretion in Escherichia coli has identified secY/prlA and secA as components of the secretory apparatus. We have examined the roles of the secY(prlA) gene product (an integral membrane protein) and the soluble secA gene product in translocation of OmpA and alkaline phosphatase precursors in an in vitro system. The protein translocation defect of the secY24 mutation ...

introduction: intracellular ph (phi) regulates essentially all aspects of cellular activities. however, it is unknown how endoplasmic reticulum (er) potassium channels sense phi. in this study, we investigate the direct effects of phi on er potassium channels. methods: we used channel incorporation into the bilayer lipid membrane method. l-α-phosphatidylcholine, a membrane lipid, was extracted ...

background: gonadotropin-releasing hormone agonists or antagonists are used in assisted reproductive technique cycles as premature luteinizing hormone secretion inhibition. studies have been reported different and contradictory results on the serum progesterone effect on intra-cytoplasmic sperm injection. objective: the purpose of this study was to evaluate the effect of serum progesterone leve...

background: the exact pathophysiology of testicular degeneration, following varicocele has not been completely understood yet.   objective: the current study was designed to determine the effect of varicocele on germinal epithelium (ge) cytoplasmic biohistochmical alterations.   materials and methods: to follow-up this study, left varicocele was induced in test groups. non-varicocelized rats we...

exploitation of the full potential of any hybrid requires the possessing of genetically high-purity seeds. commercial soybean hybrids have been developed using a cytoplasmic male sterility (cms) system. in order to avoid reduction in yield caused by using low-purity seeds, development of a simple, rapid, and accurate method for hybrid purity assessment is of great essence and significance. ther...
