The enzymatic systems which effect the biological degradation of the sulfur-containing amino acids of the protein molecule, cystine and methionine, are not well understood. Knowledge of the intermediary stages in the metabolism of these amino acids is also lacking. When either of these amino acids is administered orally or parenterally in moderate amounts to the more common laboratory animals (...

campylobacter is known to be one of the most common causes of human intestinal disorders. since poultry are known to be the main reservoirs for this pathogen, decreasing this bacterium in intestinal tract could be beneficial in reducing contamination of poultry products. the effects of probiotic (primalac®), medicinal plant (sangrovit®) and organic acid (selko-ph®) as broiler feed additives on ...

Kalanchoe pinnata leaves are used in South Asia as a natural kidney stone treatment. In vitro studies were conducted supersaturated and artificial urine solutions to evaluate the antiurolithic properties of K. leaf extract on calcium oxalate monohydrate (COM) surgically extracted stones. Key organic acids present plant also examined investigate inhibition formation. Crystals harvested from diss...

this study was carried out in order to evaluate the changes of nitrogen, phosphor and potassium uptake by wheat and remaining of them in soil under foliar application of leonardite and foliar application of n and k. the experiment was conducted in gorgan university of agricultural sciences and natural resources during 2013- 2014. the experiment was laid out a using split-plot arrangement based ...

Cu BA, T. Serum and Urine Amino Acid Analysis in Children with Biliary Atresia. Tohoku J. exp. Med., 1983, 139 (1), 61-66 Serum and urine amino acid levels were measured preoperatively and at varying time following successful hepatic portoenterostomy. All of the essential amino acids measured returned to normal levels during the late postoperative period over five years, whereas many of the non...

Refractive and absorption indices in the UV and visible region of selected aqueous organic acids relevant to tropospheric aerosols are reported. The acids investigated are the aliphatic dicarboxylic acids oxalic, malonic, tartronic, succinic and glutaric acid. In addition we report data for pyruvic, pinonic, benzoic and phthalic acid. To cover a wide range of conditions we have investigated the...

The purpose of this study was to provide a better understanding of the physiological role of endogenous net organic acid production in rats consuming their usual diet. Balance studies were performed over 24 h, and urine was collected in the day and night portions of the diurnal cycle. A supplemented low-electrolyte diet (LED) was fed to determine whether urinary organic anions were identical to...
