Vancomycin-resistant enterococci: Troublemaker of the 21st century.

The emergence of multidrug-resistant and vancomycin-resistant enterococci during the last decade has made it difficult to treat nosocomial infections. Although various enterococcal species have been identified, only two (Enterococcus faecalis and Enterococcus faecium) are responsible for the majority of human infections. Vancomycin is an important therapeutic alternative against multidrug-resistant enterococci but is associated with a poor prognosis.

Disparity in actions of rosiglitazone against cisplatin-induced nephrotoxicity in female Sprague-Dawley rats.

Cisplatin is one of the most common chemotherapeutic drugs used against various solid, tumours. Despite of its therapeutic benefits, its use in clinical practice is often limited because of dose, related toxicity. The nephrotoxic potential of cisplatin has been ascribed to its accumulation in the, renal tubular cells generating reactive oxygen species (ROS), activation of Bax, increased secretion of, TNFα and activation of certain inflammatory mediators like cytokines.
