In order to study the effects of various levels of protein in diet based on total and digestible amino acids on performance and carcass traits of broilers, an experiment was conducted as a completely randomized design with 288 broiler chicks from Cobb 500 strain in 6 treatments, each treatment consist of 3 replicates with 16 chicks per replicate. Treatments were the diets as follow: 1) diet for...

In mammals, PTH is a component in a complex signaling system involving three structurally related ligands and two G protein-coupled receptors, which share significant amino acid sequence homology (Fig. 1). PTH is a peptide hormone comprising 84 amino acids that is made by the parathyroid glands (and to a much smaller extend by the thymus) and acts through the PTH/PTH-related peptide (PTHrP) rec...

We report the absence of functional parathyroid hormone (PTH)/PTH-related peptide (PTHrP) receptors (PTH/PTHrP receptor) in Blomstrand chondrodysplasia, a genetic disorder characterized by advanced endochondral bone maturation. Analysis of PTH/PTHrP receptor genomic DNA from a patient with Blomstrand chondrodysplasia demonstrated that the patient was heterozygous for a point mutation (G--> A su...

securigera securidaca (l.) degen & dorfl grows in different parts of iran. the seeds of the species are used in iranian folk medicine as an anti-diabetic agent. many studies have established hypoglycemic effects of amino acids and in the present investigation, amino acids of securigera securidaca seeds have been evaluated. the ground seeds were extracted using petroleum ether, hot ethanol a...

Studies from our laboratory have shown that the metabolic clearance rate of carboxy terminal immunoreactive parathyroid hormone (i-PTH) can be accounted for by extraction of i-PTH by liver and kidney. In contrast, there was no demonstrable hepatic uptake of the synthetic amino terminal bovine PTH fragment (syn b-PTH 1-34) and the kidney accounted for only 45% of the metabolic clearance rate of ...

As natural plant growth stimulators, amino acids are widely used to improve the yield and quality of crops. Change in enzymes activities of N assimilation (NR, NiR and GS), residual nitrate (NO3-), soluble protein content, and yield of spinach and lettuce plants were investigated under replacing 20% nitrate-N in the nutrient solution by L-glycine and blood meal amino acids. Seeds of the mention...

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.
