Background and aim—An oral glutamine load in cirrhotic patients awaiting liver transplantation was shown to cause a rise in blood ammonia and psychometric abnormalities which were reversed by hepatic transplantation. L-Ornithine-Laspartate (LOLA) has been shown to reduce ammonia and improve psychometric function in patients with hepatic encephalopathy. The aim of the present study was to assess...

Abstract Given the significant changes taking place in geopolitical global situation, and derived supply chain issues for some traditional electric propulsion propellants like xenon, alternative issue is perceived as a strategic topic to tackle, ammonia (NH3) becoming one serious candidate. Ammonia increasingly being investigated extend green hydrogen use by overcoming storage transportation of...

The assimilation of inorganic N, in the form of ammonia, onto C skeletons for the production of amino acids is one of the most important biochemical processes in plants. In an actively growing plant, N is taken up as nitrate and to a lesser extent as ammonia. Nitrate is reduced in the cytoplasm by nitrate reductase and nitrite enters the chloroplasts where it is further reduced before incorpora...

Introduction and objective: The amount of nitrogen fixed by Azotobacter varied from 0.02-0.25 KgN/ha/d and has been reported to be variable with various physiological and environmental factors. The nitrogen fixation by mesophilic soil isolates and their analogue resistant mutants of Azotobacter chroococcum was compared with their thermotolerant mutants at three different temperatures (30 o C, 3...

OBJECTIVE Alcoholic hepatitis (AH), a unique clinical syndrome among patients with chronic and active alcohol use, is associated with high short-term mortality. An elevated ammonia level is associated with mortality in patients with acute liver failure; however, its impact in AH has not been well-studied. METHODS A retrospective study was performed on patients admitted to a tertiary-care hosp...

The ion chromatographic determination of ammonia in air using a sampling tube of porous carbon carbonized at 500 degrees C was examined. When the mean recovery and the reproducibility for a series of five determinations were examined for 1 and 10 ppm ammonia gases, the mean recovery (n = 5) and the relative standard deviation were 97.0% and 3.5% for 1 ppm and 86.9% and 2.8% for 10 ppm, respecti...

Pretreatment of miscanthus is essential for efficient enzymatic production of cellulosic ethanol. This study reports a possible pretreatment method for miscanthus using aqueous ethylenediamine (EDA) for 30 min at 180 °C with or without ammonia. The mass ratio of miscanthus to EDA was varied from 1:3, 1:1, and 1:0.5, keeping the mass ratio of miscanthus to liquid (EDA + Water) constant at 1:8. T...
