It is generally accepted that magnesium requirements increase in the elderly. Multiple reasons for this exist. In the elderly, magnesium intake tends to be low, intestinal absorption is frequently diminished, and urinary output is often enhanced. As a result, the magnesium status of aging subjects is likely to be marginal, if not frankly deficient. Because magnesium plays important roles in

Chlorides are compounds that contain chlorine along with a more electropositive element. The chloride form of any metal is generally soluble in water, with the exception of lead chloride, which is only slightly soluble, and silver chloride, which is insoluble. Antimony chloride, bismuth chlorides, and others decompose in water to create oxychlorides. Most metal chlorides can be melted without

31/7/2020· Fertilization of an egg by more than one sperm presents one of the earliest and most prevalent barriers to successful reproduction. This study shows that, as in mammals, eggs from diverse species release zinc upon fertilization; this extracellular zinc protects eggs from multiple fertilizations, revealing that this fundamental strategy may have evolved more than 650 million years ago.
About 130 million people in the United States rely on groundwater for drinking water, and the need for high-quality drinking-water supplies becomes more urgent as our population grows. Although groundwater is a safe, reliable source of drinking water for millions of people nationwide, high concentrations of some chemical constituents can pose
