Impact of the Nutritional Regimen on Protein Catabolism and Nitrogen Balance in Patients With Acute Renal Failure
2016Co-Authors: William Clark R. Md&, Bruce A. MuellerAbstract:ABSTRACT. Background: Patients with acute renal failure are in substantial negative Nitrogen Balance as a result of their ex-tremely high protein catabolic rates. We prospectively evalu-ated a series of patients with acute renal failure managed with continuous venovenous hemofiltration to determine which nu-tritional and nonnutritional variables might influence protein ca-tabolism and Nitrogen Balance. Methods: Forty consecutive pa-tients (aged 52 ± 20 years; mean ± SD) were monitored for 357 treatment days (average treatment duration 8.9 ± 8.6 days). All data (including nutritional regimen, laboratory values, APACHE II score, administered blood products, hemofiltration parameters, and medications) were collected daily. Results: For all patients, the mean normalized protein catabolic rate was 1.4 ± 0.5 g/kg per day. The rate did not differ between those who received nu-trition support and those who did not. The net Nitrogen defici

The net Nitrogen deficit was less in those patients receiving nutrition support (-6.0 ± 5.2 vs -14.0 ± 5.6 g N/d; p...

effect of thermal hydrolysis sludge supernatant as carbon source for biological denitrification with pilot scale two stage anoxic oxic process and Nitrogen Balance model establishment
Biochemical Engineering Journal, 2018Co-Authors: Kang Song, Yinghe Jiang, Xiaoyan SunAbstract:Abstract To recover carbon source (C-source) from waste activated sludge (WAS) and enhance the Nitrogen removal performance, a pilot-scale system consisting of two-stage anoxic/oxic (A/O) process and low-temperature thermal hydrolysis process (THP) was proposed. The C-source recovery parameters for pilot THP were determined by systematically considering the results of orthogonal jar experiment, hydrolyzed sludge biodegradability and actual pilot situation. The results showed that supernatant from WAS treated by pilot-scale THP showed desirable biodegradability (BOD5/SCOD 0.62) and C/N (16) at the condition of heating temperature of 80 °C, heating time of 90 min and sludge water content of 98%. The performances of two-stage A/O process for 35 days indicated that the effluent quality could comply with the preset discharge standard, and hydrolysed sludge supernatant could be utilised as C-source for biological denitrification. A Nitrogen Balance model was established for two-stage A/O process, which showed high simulation accuracy and could be applied to optimize the operation parameters to meet TN discharge standard.

effects of supplementation of panicum maximum with four herbaceous forage legumes on performance nutrient digestibility and Nitrogen Balance in west african dwarf goats
Animal Science Journal, 2008Co-Authors: Festus Tope Ajayi, Olaniyi Jacob Babayemi, Abiodun A TaiwoAbstract:The effects of supplementing a basal diet of guineagrass (Panicum maximum cv Ntchisi) (diet 5) with Stylosanthes guianensis (diet 1), Lablab purpureus (diet 2), Aeschynomene histrix (diet 3) and Centrosema pubescens (diet 5) on West African dwarf goats were evaluated. Parameters measured were feed intake, nutrient digestibility and Nitrogen Balance. Voluntary intake (g/kg W0.⁷⁵/day) of dry matter (DM) 138.73, crude protein (CP) 25.86, neutral detergent fiber (NDF) (96.29) and acid detergent fiber (ADF) (65.73) of diet 1 were not significantly different (P > 0.05) from the other diets with legume supplements. The feed intake of goats on diet 5 was lower (P < 0.05), having corresponding values of DM (108.21), CP (17.33), NDF (77.68), and ADF (53.55). Weight gain (g/day) differed (P < 0.05) in goats placed on the diets. The lowest weight gain was obtained in diet 5. The digestibilities of DM, CP, ADF and acid detergent lignin (ADL) differed (P < 0.05) in diet 1-5 except for NDF digestibility. Nitrogen Balance (g/kg W ⁰.⁷⁵/day) ranged from 0.29 in diet 5 to 0.83 in diet 2 (P < 0.05). Similarly, Nitrogen retention percentage was highest in diet 2 (35.17), with the lowest value in diet 5 (20.71). It could be concluded that a diet consisting of Panicum maximum with Lablab purpureus supplementation gave the highest performance in weight gain, Nitrogen digestibility and Nitrogen utilization. However, any of the herbaceous legumes in this study would lead to increased productivity of ruminant livestock.
