We examined body fluid regulation by weanling (21-25 days) and adult (>60 days) male rats that were offspring of dams fed chow containing either 0.1, 1, or 3% NaCl throughout gestation and lactation. Weanling rats were maintained on the test diets until postnatal day 30 and on standard 1% NaCl chow thereafter. Ad libitum water intake by weanlings was highest in those fed 3% NaCl and lowest in t...

Rhizobial symbionts were isolated from the surface (0–0.5 M) and phreatic (3.9–5.0 M) root environments of a mature mesquite woodland in the Sonoran Desert of Southern California, and from variable depths (0–12 m) of non-phreatic mesquite ecosystems in the Chihuahuan Desert of New Mexico. They were tested for their ability to tolerate high salinity, and respire NO3 2 as mechanisms of free-livin...

This study investigates the corrosion behavior of three stainless steel grades at two H2SO4 concentrations, namely 1 wt% and 10 wt%, with varying NaCl concentrations in range from 500 mg/L to 10,000 mg/L. Dissociation sulfuric acid yields hydrogen (H+) sulfate () ions, former which lowers pH value a solution while latter increases concentration ions that act as inhibitor. The equilibrium chemis...

the present study was conducted to find the effect of three heavy metals, ag, hg and pb on the expression level of a gene encoding plasma membrane h+-atpase in aeluropus littoralis. the experiment was laid out in a completely random design with three replications. the expression of the main gene was normalized to the expression of the housekeeping gene actin. two 259 and 187 bp fragments were a...

Plant tissue culture techniques were used to study the effect of NaCl on tropane alkaloids accumulation and proline content of both Datura metel and Datura stramonium. Callus cultures were established for both Datura species. However, MS medium supplemented with 1mg/l of both BA and NAA was the best for callus production in D. metel, while MS supplemented wit...

This study developed probabilistic models to describe Listeria monocytogenes growth responses in meat products with low concentrations of NaNO2 and NaCl. A five-strain mixture of L. monocytogenes was inoculated in NBYE (nutrient broth plus 0.6% yeast extract) supplemented with NaNO2 (0-141 ppm) and NaCl (0-1.75%). The inoculated samples were then stored under aerobic and anaerobic conditions at...

Light could induce phosphorylation of light harvesting chlorophyll a/b binding proteins (LHCII) in Dunaliella salina and spinach thylakoid membranes. We found that neither phosphorylation was affected by glycerol, whereas treatment with NaCl significantly enhanced light-induced LHCII phosphorylation in D. salina thylakoid membranes and inhibited that in spinach. Furthermore, even in the absence...
