Water springs: an immeasurable resource for ensuring sustainability.

Water springs are manifestations of groundwater to the surface, forming and ensuring the supply and sustainability of streams, lakes, rivers, and dams. Therefore, its riparian forest is considered an area of permanent preservation, which aims to protect the water, as well as the spring, from consequences of disordered population growth, added to deficient basic sanitation systems, climate change, agricultural activities, inappropriate land uses, unplanned urbanization, and diffuse sources of pollution. In addition to compromising water quality, many of these factors affect the permanence of water upwelling at the source, compromising the formation and continuity of streams, lakes, and rivers.

Diphenyl diselenide reverses cadmium-induced oxidative damage on mice tissues.

The concept that selenium-containing molecules may be better antioxidants than classical antioxidants, has led to the design of synthetic organoselenium compounds. In the present investigation subchronic deleterious effects of cadmium-intoxication in mice and a possible protective effect of diphenyl diselenide (PhSe)2 (5 micromol/kg) were studied. Male adult Swiss albino mice (25-35 g) received CdCl2 (10 micromol/kg, subcutaneously), five times/week, for 4 weeks.
