objective(s) motility plays a major role in pathogenicity of helicobacter pylori, yet there is scarce data regarding its chemotactic behaviour. the present study was designed to investigate the chemotactic responses of local isolates of h. pylori towards various sugars, amino acids, as well as some other chemical substances. materials and methods chemotaxis was assayed by a modified adler’s me...
addition of potassium cyanide to a mixture of schiff base and lithium perchlorate afforded a-aminonitriles in high yields. addition of potassium cyanide to a methanolic solution of schiff base and phosphoric acid afforded a-aminonitriles. when the reaction mixture was refluxed it gave a-amino acids in high yields.
In mammalian cells, the intracellular levels of the neutral amino acids are regulated to meet the nutritional needs of the cells. The cellular levels of the amino acids are maintained by balancing the uptake of amino acids from the extracellular medium and the biosynthesis of certain of the amino acids, with the requirements of the cell for amino acids for protein synthesis and energy metabolis...
in lb is research, adsorption of some amino acids and their complenation with manganese (ii) ion on carbonnanotube (mwcnt) by using of four relations langmuir, freundlich. temkin and harkins -jura imitherms wasinvestigated. from this relations. freudlich and temkin relations predict good equilibrium diagram in, isothermcondition. we could compute the theoretical constants by excel software. hy ...
background: addition of amino acids to the culture medium is beneficial for embryonic development in many species. objective: the objective of this study was to investigate the effects of amino acids on the in vitro maturation and embryonic development of the bovine oocyte. materials and methods: bovine ovaries were collected from a local abattoir and brought into laboratory. cumulus-oocyte com...
BACKGROUND Nitric oxide (NO) is essential for the optimal perfusion of the heart and its vasculature. NO may be insufficient in surgical patients because its precursor arginine is decreased, and the inhibitor of NO synthesis asymmetric dimethylarginine (ADMA) is increased. Besides arginine, the presence of other amino acids essential for the proper metabolism of cardiac cells may be decreased t...
In brief: Metabolite signatures were compared between children with normal weight, obesity, and both obesity T2DM, by measuring 273 analytes in fasting plasma a 24-hour urine sample. Twenty-two metabolites uniquely associated T2DM. Adolescents T2DM have altered purine nucleotide metabolism, betaine oxidative branched-chain amino acids (BCAAs) their catabolites.
lysozyme is one of the bioactive components of eggs with well known antibacterial potential, widely used in food industry, medicine and pharmaceutics. in this study, the possibility of quail’s egg lysozyme concentration and activity (modified via amino acids dietary supplementation) was investigated. in accordance with lysozyme amino acids profile, four amino acids of: asparagine, arginine, gly...
Seeds sterilized with sodium hypochlorite (NaOCl) retained sufficient amounts to interfere with studies of amino acid metabolism of the sterilized seeds during germination. Repeated washing in water did not remove NaOCl completely. However, soaking the seeds for 10 min in 0.01 n HCl removed NaOCl completely, without reducing germinability.Residual NaOCl reacted with the amino acids and reduced ...
In recent years, the study of gut microbiota and host lipid metabolism has received widespread attention. Firstly, diversity compositions are significantly altered in animal models lipodystrophia or human clinical trials, can also be regulated by reshaping using fecal bacteria transplantation, probiotics, nutritional interventions. In this paper, we discuss link between microbes m...
