the kinetics of the potassium thiocyanate transport mediated by dicyclohexyl-18-crown-6 (l) through a bulk liquid membrane is studied experimentally and theoretically. the proposed model is based on the assumption of a pure diffusion of the complex salt [k·l]+scn¯ through the liquid membrane stagnant films at the interfaces. it illustrates the connection between liquid-liquid extraction equilib...

BACKGROUND The UK introduced an ambitious national strategy to reduce population levels of salt intake in 2003. The aim of this study was to evaluate the impact of this strategy on salt intake in England, including potential effects on health inequalities. METHODS Secondary analysis of data from the Health Survey for England. Our main outcome measure was trends in estimated daily salt intake ...

Lead, cadmium, mercury and arsenic are the most important heavy metals which may cause health risks following consumption of contaminated foods. Table salt is one the mostly used food additive with unique place in food consumption. Although purified table salt is expected to have lower level of contamination, some Iranians still prefer to use rock salt. Use of rock salt for food purposes has be...

The aim of this study was to evaluate endothelium-dependent and -independent vasodilation, as well as endothelium biochemical markers, in a group of essential hypertensive patients classified on the basis of salt sensitivity. Changes in forearm blood flow in response to acetylcholine, sodium nitroprusside, and N(G)-monomethyl-L-arginine (L-NMMA) infusion were determined by means of strain-gauge...

Objective: To evaluate the impact of salt iodization on the prevalence of goiter among school children in the city of Shiraz. Design: In 1989, prior to initiation of universal salt iodization in Iran, 2419 male and female students, 6-18 years were randomly selected and evaluated for the presence of goiter, which was graded according to WHO goiter classification. A similar study was carried out ...

Background The salt-taste threshold can influence the salt appetite, and is thought to be another marker of sodium intake. Many studies have mentioned the relationship between the sodium intake and blood pressure (BP). The aim of this study was to evaluate the relationship between the salt-taste threshold and urinary sodium excretion in normotensive and hypertensive groups. Methods We analyze...

Introduction Since nutrition, especially in childhood and adolescence is an important effect on intelligence and learning, so that malnutrition delayed to later periods of life, so that these people during the course of studies, will have many problems, this study was conducted to evaluate the effect of nutrition on student learning. Materials and Methods This study was a cross-sectional study ...

OBJECTIVE To evaluate the effect of zinc on the appetite for salt foods in children aged 8 months to 5 years. METHOD Double-blind, placebo-controlled study. Two groups of 20 children refusing to eat salt foods were followed during 6 months. The children in the first group received zinc chelate 1 mg/kg daily for 3 months.
