The effect of low substrate concentrations on the metabolic pathway and sulfur isotope fractionation during sulfate reduction was investigated for Archaeoglobus fulgidus strain Z. This archaeon was grown in a chemostat with sulfate concentrations between 0.3 mM and 14 mM at 80 degrees C and with lactate as the limiting substrate. During sulfate reduction, lactate was oxidized to acetate, format...

BACKGROUND AND PURPOSE Felbamate is a new dicarbamate anticonvulsant with low toxicity currently being investigated in human clinical epilepsy trials. In this study, we examined the protective effects of felbamate against hypoxia. METHODS We exposed paired rat hippocampal slices to hypoxia with and without felbamate treatment while monitoring the CA1-evoked population spike. RESULTS Felbama...

Most cell growth media contain about 1 mg of choline per liter, consistent with concentrations usually employed for vitamins. One notable exception is the medium described by Waymouth (3) which contains 250 mg of choline per liter. For L cells growing in a chemically defined medium, I observed that increased choline permitted continuing growth of cells in the absence of medium replenishment ove...

This study was conducted with three hundred one-day-aged broiler chicks (Ross 308) to determine the impact of adding two different doses zinc sulfate drinking water on physiological traits broilers. At first, 300 were randomly distributed into groups. They reared in floor cages until they 42 days old, as follows: The 1st group (control group) given without any additives. 2nd and 3rd groups fort...

Acute pancreatitis (AP) is a life-unpleasant situation with contradictory and inadequate treatments. In this regard, the present study evaluated effect of possible pretreatment lipase-pancreatin on L-arginine-induced AP. Forty adult mice were selected divided into five groups: I) control group, II III) AP groups (i.p.) receiving L-arginine 2×300 2×400 mg/100 g body weight (b.w.), IV) (2×300 L-a...

zinc has previously been reported to alleviate salinity stress in plants. in this study, we monitored various biomass and chlorophyll fluorescence parameters to determine the optimum zinc sulfate concentration that can be used as foliar spray to alleviate salinity stress in glycine soja. the plants subjected to a series of salinity levels (nacl concentration of 0, 100, 200, and 300 mmol l-1), a...

A one-step, single use, disposable Alkaline Phosphatase (ALP) biosensor has been developed. It is based on the detection of phenol produced by an ALP enzymatic reaction. It can operate at 25 °C in a pH 10 medium. It measures ALP of 0-300 IU/L. The permissible concentrations of glucose, ascorbic acid and urea without interference are 10 mM/L, 5 mg/L and 400 mg/L, respectively. Experimental resul...

Diabetic kidney disease (DKD) is one of the most debilitating complications type 2 diabetes mellitus (T2DM), as it progresses silently to end-stage renal (ESRD). The discovery novel biomarkers early DKD becomes acute, its incidence reaching catastrophic proportions. Our study aimed quantify previously identified metabolites from serum and urine through untargeted ultra-high-performance liquid c...
