The rate of protein synthesis in the whole body was measured in one fed subject with seven 15N-labelled amino acids (intravenous and oral doses) and two 15N protein mixtures (oral doses only). The rates were determined individually from the urinary excretion of ammonia and total urea over a 12 h experimental period. Except with oral glycine and alanine, the synthesis rates given by ammonia and ...

Nitrogen management practices have an effect on crop yields but they can also have a negative impact on the environment. Practices such as banding fertilizer and/or split-applying total nitrogen needs per acre offer a more efficient use of nitrogen by significantly reducing nitrate leaching potential. Heavy rains occurring when plants are small and nitrogen demands are low can also increase nit...

BACKGROUND Thus far, there have been no controlled studies to examine optimal levels of energy provision in critically ill patients with acute renal failure (ARF) receiving artificial nutrition. METHODS After a 24 h nitrogen-free regimen (20% dextrose), we assigned during an open-label, AB/BA-crossover-trial, 10 ARF patients receiving both total parenteral nutrition (TPN) and renal replacemen...

Paddy being cultivated since about 10,000 years B.C in Ganga Valley in India, its production reached up to 99 million tons in the year 2012. BGA are of much ecological importance for maintaining the soil fertility and reclaiming the alkalinity. In present investigation attempts were made to identify the local cyanobacterial genera from the paddy fields, BGA application for green farming enablin...

This study was conducted to investigate the effects of different levels of peptide supplementation on rumen fermentation pattern, digestibility and microbial protein synthesis. Three rumen-cannulated Holstein dairy cows were used in a 3 × 3 Latin square experiment within 21 days period. The ruminal infusion of sodium caseinate (CN) was 0 (control), 50 and 100 g/d. Dry matter intake, milk yield ...

For many years, the urea cycle was considered to be relatively unimportant in the life history of most teleost fishes. In previous studies, we were surprised to find that newly hatched freshwater rainbow trout embryos had relatively high activities of the key urea cycle enzyme, carbamoyl phosphate synthetase III (CPSase III), and other enzymes in the pathway, whereas adult trout had much lower ...

in order to study the effects of organic and inorganic nitrogen sources on quantitative and qualitative characteristics of three winter rapeseed cultivars, a field experiment was carried out as factorial arrangement in complete block design with three replications in agricultural and natural resources research center of markazi province, arak, during 2008-2009 growing season. three rapeseed cul...

to study the effects of simultaneous application of urea, znso4 and inoculants, (azotobacter and azospirillum), on uptake and nitrogen use efficiency in rapeseed, var. hyola308, a field experiment with split plot factorial layout based on a randomized complete block design was conducted at the research field of faculty of agricultural science, university of guilan in 2008. experimental treatmen...

a trial study was set to assess the influence of the plant residue management in conjuction with application of different nitrogen sources on accumulation and translocation of wheat stem reserves, at the agricultural faculty of shahid chamran university of ahvaz during 2011-2012. the experimental design was split plot at randomized completed block design arrangement. the main plot were differen...

This study aimed to determine excretion rates of ammonia and urea of Australian short-finned Ž . elvers as influenced by varying dietary crude protein intake. Elvers 2.3"0.02 g were fed diets Ž . Ž . Ž . Ž . containing dietary crude protein levels of 25% P25 , 35% P35 , 45% P45 and 55% P55 dry Ž matter equivalent to 14.17, 19.24, 20.57 and 26.39 g CPrMJ, respectively pairs of diets P25, P35 . a...
