background : adiposity is correlated with metabolic complications, such as insulin resistance, glucose intolerance, hypertension etc. that finally can lead to coronary heart disease (chd). physical activity plays an important role in prevention of these diseases. we aimed to study body fat and plasma lipids and lipoproteins in different levels of physical fitness; also to examine any relationsh...

introduction: hypercholesterolemia is a metabolic disorder that ultimately results in arterial sclerosis and complications like hypertension and coronary arterial diseases. various drugs have been used for the treatment of this condition and many studies are underway for introducing new drugs. chitosan and salvadora persica are two such drugs. chitosan is produced by deacetylation of chitin whi...

background antioxidant compounds have been shown to slow down the development of chemically induced tumors. it has been estimated that most of human cancer cases are due to environmental factors and would be preventable if the main risks could be identified. the potential of vitamin e as a cancer preventive agent has been studied and individuals whose intake of vitamin e was above average showe...

human serum paraoxonase (pon) associated with high density lipoprotein (hdl) , has been postulated to have a role in protecting low-density lipoprotein (ldl) against oxidative damage, which has led to the proposal that pon is an anti-atherogenic and anti-inflammatory enzyme. it has genetic polymorphism at the 191 (r ->q) and two alloenzymes a and b and three phenotypes a, b, and ab. we examined...

In 1973, experimental evidence was reported in support of the view that water polarized in multilayers rather than simple lipid is responsible for the semipermeable properties of living cell membranes. The present article presents a full rebuttal to a subsequent attack on that view.
