Besides fluorine, oxygen is the most electronegative element with the highest reduction potential in biological systems. Metabolic pathways in mammalian cells utilize oxygen as the ultimate oxidizing agent to harvest free energy. They are very efficient, but not without risk of generating various oxygen radicals. These cells have good antioxidative defense(More)
Ca2+ accumulates in the nucleus and DNA undergoes enzymatic cleavage into internucleosome-length fragments before acetaminophen and dimethylnitrosamine produce hepatic necrosis in vivo and toxic cell death in vitro. However, Ca(2+)-endonuclease fragmentation of DNA is characteristic of apoptosis, a type of cell death considered biochemically and(More)
Extracts of Salacia reticulata Wight (Hypocrataceae) roots, stems, and leaves have been used in Asia for hundreds of years for the folkloric treatment of diabetes and other health problems. Constituents that have been identified as exhibiting anti-diabetic effects include salacinol, kotalanol, ponkorinol, salaprinol, and their corresponding de-0-sulfonated(More)
Doxorubicin (DOX), a prominent anticancer agent has enjoyed considerable popularity in the last few decades because of its usefulness in the management of various forms of cancers, but its organotoxic potential (cardio-, hepatoand nephrotoxicity) has constrained on its clinical use. This study investigated whether DOX has the ability to cause nephrotoxicity(More)
Curcumin (CUR; diferuloylmethane), a rhizome extract of Curcuma Longa L. is commonly used as a food coloring and flavoring agent. Although oriental and Ayurvedic medicines have traditionally used CUR in the treatment of diseases, conventional medicine has just begun to recognize its potential therapeutic value. Numerous recent studies have demonstrated the(More)
Treatment during early tumor development has greater success because tissue growth remains largely confined to its original locus. At later stages, malignant cells migrate from their original location, invade surrounding normal areas, and can disseminate widely throughout the body. Remodeling of the extracellular matrix (ECM) serves as a key facilitator of(More)
A novel dietary supplement composed of three well-known phytochemicals, namely, Salvia officinalis (sage) extract, Camellia sinensis (oolong tea) extract, and Paullinia cupana (guarana) extract, and two prominent vitamins (thiamine and niacin) was designed to provide nutritional support by enhancing metabolism and maintaining healthy weight and energy. The(More)
Type I Diabetes is characterized by the presence of hyperglycemia due to insulin deficiency and consequent impaired hepatic glucose metabolism. During diabetes, the liver becomes the most important tissue for the regulation of serum glucose. However, elevated glucose causes continuous oxidative damage to the liver, reducing its capacity to ameliorate(More)
