Resumen

A primed constant infusion of [15N2]urea was used to quantify the response of urea production to exercise at 40 and 70% maximal oxygen consumption on a treadmill. Total urea production, urea production from recycled N, urea production from nonrecycled N, and urea N recycled back into body protein were calculated. Most components of urea kinetics were unaffected by exercise at either intensity. The rate of urea reincorporated into protein was significantly increased during exercise and recovery at both levels of exercise. We conclude that exercise does not stimulate urea production but that the

Resumen

To provide reference for scientific management of nitrogen (N) fertiliser on tartary buckwheat, the effects of the mixed application of controlled-release N fertiliser (a kind of thermoplastic polymer-coated urea types that are characterised by a semi-permeable membrane) and common urea was studied in the main tartary buckwheat production area in China. In 2018 and 2019, a two-year field experiment was conducted a randomised block design with five treatments: (1) no nitrogen fertilisation (CK); (2) 100% N from common urea (T1); (3) 15% N from controlled-released urea fertiliser (plastic coated

Resumen

Urea production rate (Ra) is commonly measured using a primed continuous tracer urea infusion, but the accuracy of this method has not been clearly established in humans. We used intravenous infusions of unlabeled urea to assess the accuracy of this technique in normal, postabsorptive men under the following four different conditions: 1) tracer [13C]urea was infused under basal conditions for 12 h (control); 2) tracer [13C]urea was infused for 12 h, and unlabeled urea was infused from hours 4 to 12 at a rate twofold greater than the endogenous Ra (“step” infusion); 3) tracer [13C]urea was infu

To discuss the internal effect of urea (CO(NH2)2) pretreatment on anaerobic digestion biogas production of rice straw waste, a self-designed laboratory-scale continuous anaerobic biogas digester was used in this study. Anaerobic biogas slurry, urea pretreatment and anaerobic digestion were evaluated for biogas production from rice straw. The results showed that the peak value of biogas production was attained on the 17th day by using 6% urea pretreatment on rice straw. However, the highest CH4 content was 49.8% on the 15th day for the 8% urea-treated rice straw. The cumulative biogas productio

Resumen

Understanding the redistribution and fate of N is essential for justification of Best Management Practices (BMP). This project was conducted on a Hecla fine sandy loam (sandy, mixed, Aquic Haploboroll) soil at the BMP field site near Oakes, North Dakota. One objective of this investigation was to evaluate the residence times of N03- -N in 20 undisturbed lysimeters and its infiltration time through the soil profile to tile drains. Corn (Zea mays L.) was fertilized with 135 kg N ha -1 as ??N-enriched urea plus 13.5 and 48.1 kg N ha -1 preplant for 1993 and 1994, respectively. Urea-N was band app

Resumen

Ammonia, an end-product of protein and amino acid catabolism toxic to the brain, must be removed quickly from the circulation. Its removal is achieved in two steps: glutamine synthesis and urea synthesis. Hyperammonemia results from either an excess of production or defective elimination. There are two main etiologies of hyperammonemia: inherited or acquired. Inherited causes are mainly related to defective elimination while acquired ones result either from excess production or deficient detoxification. Good laboratory diagnostic tools are necessary to make the right diagnosis.

Resumen

The main focus in the non-dialytic management of patients with acute kidney injury (AKI) is the prevention and treatment of complications.Nutritional support is an important aspect as many patients tend to be hypercatabolic, thus requiring adequate caloric intake, yet without administration of excessive fluid volumes. Inadequate nutrition in AKI may lead to enhanced production of urea nitrogen and azotaemia. However, hyperglycaemia is a frequent complication in these patients, often requiring continuous insulin therapy to achieve the recommended blood glucose target range of 110–150 mg/dL (6.1

Resumen

In the preserved grain, urea, when subjected to hydrolysis, secretes am-MIAC, protecting it from self-heating and spoilage, and the other part of it goes to ammonium compounds, thereby increasing the protein nutrition of the grain. Processing of grain with urea contributed to a decrease in the concentration of protein, both soluble — by 3.24%, and cleavable-by 4.01%, compared with the control. The cost of processing 1 ton of grain with urea is 1.72 times cheaper than conventional drying. The profitability of milk production increased by 26.62%.

Resumen

Energy integration and cogeneration are commonly used in large mineral fertilizer production complexes for many years. Production of nitrogen fertilizers is an energy intensive industry branch consuming about 5200 PJ of fossil fuels, mainly natural gas. Urea is the major straight nitrogen fertilizer with 46% nitrogen content, and the total production of 155 MM metric tons yearly. About 600–900 kg MP or HP steam and 50–120 kWh electricity per ton urea are consumed in modern low energy urea plants.

Resumen

Effects of exogenous urea infusion on glucose metabolism in acute heat stressed swamp buffaloes. Five buffaloes kept in normal ambient temperature showed no significant changes in the heart rate, respiratory rate, packed cell volume, glucose turnover rate, glucose pool size, glucose clearance, glomerular filtration rate (GFR), effective renal plasma flow (ERPF), plasma concentration of electrolytes, protein and creatinine during intravenous infusion of urea for 4 h. The rate of urine flow, fractional urea excretion, urinary potassium excretion and osmolar clearance significantly decreased on t

Resumen

Electrogenic bacteria produce power in soil based terrestrial microbial fuel cells (tMFCs) by growing on electrodes and transferring electrons released from the breakdown of substrates. The direction and magnitude of voltage production is hypothesized to be dependent on the available substrates. A sensor technology was developed for compounds indicative of anthropological activity by exposing tMFCs to gasoline, petroleum, 2,4-dinitrotoluene, fertilizer, and urea. A machine learning classifier was trained to identify compounds based on the voltage patterns. After 5 to 10 days, the mean voltage

Resumen

This research project entitled "Influence of Ruminal Starch Degradability on Performance of High Producing Dairy Cows" had the following objectives: a) Determine effects of feeding varying amounts of ruminally degradable starch (RDS) on efficiency of milk and milk protein production; and 2) Investigate digestive and metabolic mechanisms relating to lactation responses to diets varying in ruminal and total starch degradability. Four lactation studies with high producing cows were conducted in which steam-flaked (~ 75% RDS) was compared with dry-rolled sorghum (~ 50% RDS) grain. All studies demo

Resumen

The effect of rumen available protein amino acids and carbohydrates on microbial protein synthesis, amino acid flow and performance of high yielding dairy cows was studied. A significant relationship between the effective degradabilities of OM in feedstuffs and the in vivo ruminal OM degradation of diets of dairy cows was found. The in situ method enabled the prediction of ruminal nutrients degradability response to processing of energy and nitragenous supplements. The AA profile of the rumen undegradable protein was modified by the processing method. In a continuous culture study total N and
