Urea is the major nitrogen form supplied as fertilizer in agricultural plant production but also an important nitrogen metabolite in plants. We report the cloning and functional characterization of AtDUR3, a high-affinity urea transporter in plants. AtDUR3 contains 14 putative transmembrane-spanning domains and represents an individual member in Arabidopsis that belongs to a superfamily of sodi...
This study was designed to investigate the clinico-haemato-biochemical, rumen fl uid and peritoneal fl uid alteration in buffaloes with peritonitis. Buffaloes with peritonitis had anorexia, dehydration, abdominal distension, ruminal atony, pain, fever, reduced milk yield and loss of defecation. Pungent smelling peritoneal fl uid was yielded on abdominocentesis. Hemato-biochemical alterations re...
The objective of this study was to determine the effects of feeding on the excretory nitrogen (N) metabolism of the giant mudskipper, Periophthalmodon schlosseri, with special emphasis on the role of urea synthesis in ammonia detoxification. The ammonia and urea excretion rates of P. schlosseri increased 1.70- and 1.92-fold, respectively, within the first 3 h after feeding on guppies. Simultane...
The objective of this study was to compare the bioefficacy of L-lysine sulfate relative to L-lysine⋅HCl for 10 to 20 kg pigs. Two experiments were conducted to determine the bioefficacy of the two sources of lysine using daily gain, feed conversion, plasma urea nitrogen and nitrogen retention as the response criteria. In experiment 1, 168 crossbred barrows (Landrace×Large White), weaned at 28±3...
Animals transplanted with the MAC16 colon adenocarcinoma showed a loss of body weight as the tumor weight increased, without a reduction in food intake. Both adipose tissue and muscle mass decreased in tumorbearing animals, although loss of body fat exceeded that of muscle mass for given tumor weight. Urinary nitrogen excretion was significantly elevated when the weight loss did not exceed 3 to...
Animals transplanted with the MAC16 colon adenocarcinoma showed a loss of body weight as the tumor weight increased, without a reduction in food intake. Both adipose tissue and muscle mass decreased in tumor-bearing animals, although loss of body fat exceeded that of muscle mass for given tumor weight. Urinary nitrogen excretion was significantly elevated when the weight loss did not exceed 3 t...
Aureococcus anophagefferens is a harmful alga that dominates plankton communities during brown tides in North America, Africa, and Asia. In order to figure out the processes of nitrogen assimilation in a Chinese strain of A. anophagefferens, RNA-seq technology was used to examine transcriptomic differences in A. anophagefferens that was grown on urea, nitrate, or a mixture of urea and nitrate, ...
The biopsy channel of the colonoscope was used in a novel approach to the study of in vivo colonic nitrogen metabolism in 12 subjects. A tracer dose of 15N15N-urea was placed in the caecum in six and distal to the splenic flexure in six. The urine and stool were collected for 72 hours and isotopic enrichment was measured in a mass spectrometer. A similar proportion of the dose was recovered in ...
