Meldrum, Kirstan K., Daniel R. Meldrum, Xianzhong Meng, Lihua Ao, and Alden H. Harken. TNF-dependent bilateral renal injury is induced by unilateral renal ischemiareperfusion. Am J Physiol Heart Circ Physiol 282: H540–H546, 2002; 10.1152/ajpheart.00072.2001.—While tumor necrosis factor (TNF)is an important mediator of renal ischemiareperfusion (I/R) injury, its role in contralateral renal injur...

Ischemia-reperfusion injury, a common complication during liver surgery where steatotic livers are more prone to the injury, may become more prevalent in the growing obese population. This study characterizes liver morphology toward understanding changes in subcellular function in steatotic livers exposed to ischemiareperfusion injury through quantitative description of fluorescein distribution...

OBJECTIVES Recent studies have revealed that nitric oxide (NO) in concert with lipid peroxidation (LP) may play an important role in pathophysiological mechanism(s) of cerebral ischemia. In addition, hyperglycemia exaggerates the pathological changes during cerebral ischemia. The purpose of this study was to investigate the effects of vitamin E (VE) on LP, NO production, and superoxide dismutas...

Lung Cell. Mol. Physiol. 278: L3–L12, 2000.—Intestinal ischemia-reperfusion commonly occurs in critically ill patients and may lead to the development of remote organ injury, frequently involving the lu...

SEE PAGE 47 A MP-activated protein kinase (AMPK) is a molecular energy sensor that is essential to the stress response in the heart (1). AMPK is activated during energy imbalance, when the ADPor AMP-toATP ratio increases. Because few proteins have adenine nucleotide binding domains, the activation of a protein kinase, which phosphorylates numerous downstream proteins, amplifies the energy stres...

Epidemiological studies show that particulate matter (PM) is the principal instigator of some adverse clinical symptoms involving cardiovascular diseases. PM exposure can increase experimental infarct size and potentiate myocardial ischemia and arrhythmias in experimental MI models such as ischemia-reperfusion (I/R) injury.The present study was aimed to evaluate the effects of particulate matte...
