85Kr as an Environmental Contaminant

Perchlorate as an environmental contaminant.

Perchlorate anion (ClO4-) has been found in drinking water supplies throughout the southwestern United States. It is primarily associated with releases of ammonium perchlorate by defense contractors, military operations, and aerospace programs. Ammonium perchlorate is used as a solid oxidant in missile and rocket propulsion systems. Traces of perchlorate are found in Chile saltpeter, but the us...

Oxytetracycline as environmental contaminant in arable lands.

Oxytetracycline (OXY) is a broad-range antimicrobial routinely used in pig production, at doses in the range of few g/kg of medicated feed, during the weaning period. It could persist at ppm level in pig liquid manure that routinely is used for organic fertilisation. In the present work we describe a methodology to study OXY environmental fate in arable land where crops are cultivated for anima...

Maximum contaminant levels and environmental injuries.

Assessment of environmental contaminant-induced lymphocyte dysfunction.

Although it has been established that environmental contaminants can alter immune function, the mechanisms of action have yet to be determined. This paper reviews the effects of hydrocarbon environmental contaminants on lymphocyte function and presents an approach which may serve to delineate the mechanisms of action. The approach is based on the use of the developmental phases of an immune res...

Curcumin as an Environmental Potent Antioxidant Decreases Risk of Arthrosclerosis

Background & Aims of the Study: Oxidative stress increases platelet-derived growth factor (PDGF) gene expression in endothelial cells that contributes to vascular dysfunction and atherosclerosis. Oxidative stress generates by dys-regulated redox balance between ROS producing systems and antioxidant systems. Also, Curcumin (Cur) as a main part of tur...
