Studies on Selected Microbial Biotransformations of Arsenic Compounds
Arsenic is an element with a notorious history and reputation used both as a poison and a cure in its past. It has a complex biogeochemical cycle in nature which was investigated. The major portion of this project looked primarily at arsenobetaine. Arsenobetaine is a benign form of arsenic that is …

Effects of sulfur complexation on intestinal transport and toxicity of metalloids in cell cultures
Arsenic is a common poison and is classified as human carcinogen. Selenium is an essential nutrient, but is highly toxic when applied in high concentrations. The cytotoxic potential of both metalloids is modified when they form sulfur-containing complexes. For arsenic compounds, only some data …

Arsenic Toxicity and Altered Mitochondrial Bioenergetics in Response to Oxidative Stress
Environmental exposure to arsenic is a worldwide health concern which is linked to a number of diseases. Areas with arsenic levels above the current safe concentration have higher levels of skin, lung, liver, and bladder cancers and non-carcinogenic pathologies, including neuropathy, cardiovascular …
