Prognostic value of procalcitonin in infection-related mortality of cancer patients.

Purpose: Infectious diseases are a major cause of morbidity and mortality in cancer patients. Tumor-induced inflammatory responses may increase the value of classical inflammatory markers in blood, so these markers may not be as useful in cancer patients as in non-cancer patients. Serum procalcitonin (PCT) is a sensitive and specific biomarker for severe infection, and has been shown to be unaffected by tumor-induced inflammatory response.

Assessment of genotoxicity in rats treated with the antidiabetic agent, pioglitazone.

Pioglitazone (PIO), a member of the thiazolidinedione class of antidiabetic agents, specifically targets insulin resistance. Drugs of this class act as ligands for the gamma subtype of the peroxisome proliferator-activated receptor. Although troglitazone, another drug in this class, displayed unacceptable hepatotoxicity, PIO was approved for human use by the U.

Genotoxicity in rats treated with the antidiabetic agent, rosiglitazone.

Rosiglitazone (RSG), a member of the thiazolidinedione class of antidiabetic agents, improves glycemic control by increasing insulin sensitivity. The therapeutic mode of action of RSG involves its activity as a highly selective and potent agonist for peroxisome proliferator-activated receptor-gamma. Although other drugs in this class have displayed unacceptable hepatotoxicity, RSG was approved for human use.
