Statins exhibit anti-leukemic properties due to suppression of the mevalonate pathway by the inhibition of 3-hydroxy-3-methylglutaryl coenzyme A reductase, and subsequent depletion of cholesterol, farnesylpyrophosphate, and geranylgeranylpyrophosphate. We investigated the role of autophagy, a controlled intracellular self-digestion, in the anti-leukemic...

Clostridium difficile intestinal infection is a major nosocomial hazard in patients receiving antimicrobial therapy. Rationale for rapid diagnosis include lifesaving antimicrobial therapy in patients with severe colitis and early isolation measures for transmission control. We have therefore analysed the sensitivity...
