Salt bridges are known to play an essential role in the thermodynamic stability of the folded conformation of many proteins, but their influence on the kinetics of folding remains largely unknown. Here, we investigate the effect of Glu-Arg salt bridges on the kinetics of α-helix folding using temperature-jump transient-infrared spectroscopy and steady-state UV circular dichroism. We find that g...

Salt preference was assessed in 60 adults of 18-21 yrs of age (30 males and 30 females) and in 60 children of 7-12 yrs of age (30 boys and 30 girls). Subjects rated the preference on Likert scale for popcorns of five salt concentrations (OM, 1M, 2M, 3M and +3M). Statistical analysis using Two way ANOVA revealed statistically significant effect of age and sex on salt preference (F4,100 = 15.027,...

aim: there is conclusive scientific evidence of the adverse effect of excessive salt consumption on health, particularly on blood pressure, leading to cardiovascular disease (cvd), gastric cancer, osteoporosis, cataracts, kidney stones, diabetes and obesity. we investigated the determinants of salt consumption among the rural women in chabahar (iran) by applying the theory of planned behavior. ...

Most angiosperms — and all major crops — are unable to withstand high concentrations of sodium chloride. Soils containing concentrations of salt amounting to a few hundred millimolar occur naturally, of course, and saline land is estimated to represent between 2.3 and 6.4% of global land surface [1]. As much as 13% of cultivated land is thought to be salt-affected. In some instances, however, a...

The progression of renal disease displays several characteristics, including proteinuria, apoptosis, inflammation, and fibrosis. In this study, we investigated the effect of long-term infusion of kinin in protection against salt-induced renal damage in Dahl salt-sensitive rats. Dahl salt-sensitive rats were fed a high-salt diet for 2 weeks and were then infused with bradykinin (500 ng/h) via su...

We determined the effect of plasma obtained from rats treated with DOCA-salt for 6 and 28 days on sodium pump activity, measured as ouabain-sensitive Rb+ uptake in tail arteries from these rats. The effect of an electrolytic lesion in the area of the anteroventral third cerebral ventricle (AV3V) before DOCA-salt treatment was investigated in relation to the ability of plasma to inhibit vascular...

During high-salt diet endogenous dopamine (DA) reduces jejunal sodium transport in young but not in adult rats. This study was designed to evaluate whether this effect is mediated, at the cellular level, by inhibition of Na+-K+-ATPase activity. Enzyme activity was determined in isolated jejunal cells by the rate of [γ-32P]ATP hydrolysis. Cells were obtained from weanling and adult rats fed eith...

Salt sensitivity of blood pressure (BP) is an independent risk factor for cardiovascular morbidity. Up to 50% of patients with essential hypertension are salt-sensitive, as manifested by a rise in BP with salt intake. Several genetic variations have been identified as being associated with salt sensitivity. The present study aimed to review the evidence on the effect of gene polymorphisms on th...

Strawberry is considered as a salinity sensitive species and is adversely affected in response to the salt stress in terms of growth and yield. Pot experiments were conducted to determine the effect of exogenous salicylic acid (SA) application on physiology, growth, chlorophyll and mineral content of strawberry grown under salt stress and greenhouse conditions. Strawberry plants were treated wi...
