One of the new strategies for the prevention of HIV acquisition is the use of microbicides such as topical microbicides including antimicrobial and antiviral peptides. Ideally, new drug candidates should kill pathogens without determent to the normal bacterial flora considered important in health; such as hydrogen peroxide producing Lactobacillus species. The antimicrobial peptides LL-37 and LS...

Previous studies have shown that alfalfa shoot biomass has the ability to bind a significant amount of various individual metals from aqueous solutions. Since most heavy metal-contaminated waters contain more than one heavy metal, it was necessary to determine the binding abilities of the alfalfa biomass with multi-metal solutions. Multi-metal binding capacity experiments resulted in the follow...

INTRODUCTION Even though dehydration could aggravate formation of urinary calculi, the effects of fluid and food restriction on calculus formation is not thoroughly defined. The purpose of this study is to evaluate the effects of fluid and food restriction in Ramadan fasting on urinary factors in kidney and urinary calculus formation. MATERIALS AND METHODS Fifty-seven men aged 30 to 55 years ...

BACKGROUND Underground water is an important natural resource serving as a reliable source of drinking water for many people worldwide, especially in developing countries. Underground water quality needs to be given a primary research and quality control attention due to possible contamination. This study was therefore designed to determine the physico-chemical and bacteriological quality of bo...

Two trials were conducted to study ruminal lactic acid, histamine, tyramine and tryptamine concentrations following glucose engorgement in vitro and in vivo. Also, electrolyte changes in rumen fluid, blood plasma and urine during lactic acidosis were examined. Experiment 1 involved the addition of glucose to rumen fluid in vitro. After 30 hr of incubation, decreases in pH and increases in lacti...

The contribution of magnesium to cell differentiation is not clear. Some studies indicate that low extracellular magnesium promotes cell differentiation, while others reach opposite conclusions. We evaluated the effects of different concentrations of extracellular magnesium on the differentiation of three in vitro experimental models: human endothelial cells seeded onto Matrigel; phorbol ester-...

background:the aim of this study is to investigate the association ofcalcium and magnesium concentration of drinking water with cardiovascular disease (cvds) in urban and rural areas of a city in iran. methods:this case-control study was conducted in 2012 in khansar county in isfahan province, iran. we used the official data of the provincial health center regarding the chemical analysis data o...

The effect of dietary calcium chloride vs. calcium carbonate on mineral metabolism was studied in cats. Ovariectomized cats and female kittens were fed purified diets with a normal calcium level (9.5 mmol Ca/MJ) but containing either calcium carbonate or calcium chloride, or were fed diets with a high calcium level (17.7 mmol Ca/MJ) containing either calcium carbonate alone or equimolar amounts...
