Inhibition of recombinant D-amino acid oxidase from Trigonopsis variabilis (TvDAAO) activity in the presence of different sodium salts and potassium chloride is reported. A competitive inhibition pattern by sodium chloride was observed, and an inhibition constant value of K(i) = 85 mM was calculated. Direct connection of NaCl inhibition with FAD cofactor dissociation was confirmed by measuring ...

Previous investigations have confirmed the potential effectiveness of various metabolic stimulants and physiological salt solutions in supporting broiler embryogenesis. The current study investigated the effects of the same solutions on chick posthatch performance and tissue nutrient profiles. In the first of 2 trials, 200 μL each of a (i) 0.18 mM carbohydrate electrolyte nutrient (CEN) solutio...

Diets high in sucrose or fructose have been shown by others to induce a modest elevation of blood pressure in rats. The present experiments were conducted to determine whether the sucrose-induced increase of blood pressure is dependent on the intake of sodium chloride. Four groups of Sprague-Dawley rats were studied: 1) a group maintained on a low salt diet and distilled water (0.45% sodium chl...

This research examined the effect of chemical factors (pH, sodium chloride, sugars (glucose and sucrose), preservatives (benzoic acid and sorbic acid)) and clove oil to decrease the growth of film yeasts (Saccharomyces cerevisiae J1, Candida krusei J2 and Candida krusei J3) on fermented bamboo shoots. All yeasts grew at pH 3.0-7.0 and did not grow greater than 7.5%(w/v) of sodium chloride conce...

Larvae of the alkali fly Ephydra hians, from Mono Lake (California), were exposed to osmotic concentrations ranging from distilled water to over 6000 mOsm of either alkaline Mono Lake water, or non-alkaline sea water/sodium chloride solutions. Larvae were capable of both hyperand hypo-osmotic regulation of haemolymph osmolality (at around 300mOsm) in Mono Lake water, but this ability was less e...

Kidney collecting duct principal cells play a key role in regulated tubular reabsorption of water and sodium and secretion of potassium. The importance of this function for the maintenance of the osmotic homeostasis of the whole organism motivates extensive study of the ion transport properties of collecting duct principal cells. We performed experimental measurements of cell volume and intrace...
