improve forage quantity and quality using organic and biological fertilizers production of important needs in dryland farming systems of the country. in this study the effects of foliar application of four different combinations of amino acid four different time steps were germinated plant growth, stem elongation, flowering and spraying all three steps above with the control treatment was carri...

Intestinal perfusion studies performed in man have suggested that amino acid nitrogen may be absorbed more rapidly from peptides than free amino acids. The aim of the present study was to compare the effects of the oral administration of peptides and free amino acids. Two isonitrogenous liquid test meals, one containing 50 g of a partial enzymic hydrolysate of fish protein in which approximatel...

results in patients with an svr, the serum levels of aminotransferases were decreased after hcv eradication. although general liver functional tests (albumin and total bilirubin) did not significantly change, the btr values significantly increased. however, in patients without an svr, an improvement in the btr value was not observed after ifn treatment. conclusions hcv eradication can improve t...

using uv-vis spectrophotometric method, the formation constant for interaction of fe2+(aq) ion with l-alaninewas experimentally studied at ph = 4.1 ± 0.01 (50mm of potassium hydrogen phthalate buffer), ionic strengthof 0.1m potassium nitrate and at 5 different temperatures 15,20, 25,30 and 35 t. the optical absorption spectraof mixtures containing considered cation and l-alanine were analyzed b...

TADA, K., Y OSHIDA, T. and ARAAAWA, Ts. Free Amino Acid Pattern in the Liver from the Patients with Amino Acid Disorders: Postmortem Diagnosis of Inborn Errors of Amino Acid Metabolism. Tohoku J. exp. Med., 1970, 101 (3), 223-226 Free amino acid concentrations were determined in the liver biopsied or autopsied from the patients with amino acid disorder and from several controls. The results sho...

Previous investigations with yeast have examined the effect of variations in the availability of the internal free amino acids on the capacity of resting cells to synthesize maltase. Control over the free amino acid pool as a source of nitrogen for protein synthesis was achieved by the use of analogues of amino acids (Halvorson and Spiegelnan, 1952) and by nitrogen starvation and replenishment ...

the effect of a selected autochthonous starter culture made up by streptococcus thermophilus, lactobacillus delbrueckii subsp. lactis and lactobacillus helveticus on the microbiological and physicochemical properties of pecorino romano cheese during ripening was investigated. the suitability of the experimental starter culture was tested at industrial scales in cheese-making trials of pecor...

The true ileal digestibility assay provides the most informative measure of digestibility to assess bioavailability of amino acids in foods for humans. To determine 'true' estimates of ileal amino acid digestibility, requires that endogenous amino acids present in digesta at the terminal ileum be quantified. The amounts of endogenous amino acids in ileal digesta can be determined after feeding ...

The process of leaf senescence is biochemically characterized by the transition from nutrient assimilation to nutrient remobilization. The nutrient drain by developing vegetative and reproductive structures has been implicated in senescence induction. The steady-state levels of amino acids in senescing leaves are dependent on the rate of their release during protein degradation and on the rate ...
