The nitric oxide donor, V-PYRRO/NO, protects against acetaminophen-induced nephrotoxicity in mice.

abstract：:Colicins are unusual bacterial toxins because they are directed against close relatives of the producing strain. They kill their targets in one of three distinct ways; via a ribonuclease or deoxyribonuclease activity or by forming pores in the target cell's membrane. This review deals with the steps involved in pore-f...

abstract：:Ozone (O3), a pulmonary irritant, and a major toxic component of photochemical smog, is capable of inducing pulmonary inflammation characterized by recruitment of polymorphonuclear leukocytes (PMNs) into the lung. The recruited PMNs, in turn, can release toxic mediators and produce lung injury. The mechanism of ozone-...
