Our laboratory has previously reported that acetaminophen confers functional cardioprotection following cardiac insult, including ischemia/reperfusion, hypoxia/reoxygenation, and exogenous peroxynitrite administration. In the present study, we further examined the mechanism of acetaminophen-mediated cardioprotection following ischemia/reperfusion injury.(More)
Acetaminophen, a popular analgesic and antipyretic, has been found to be effective against neuronal cell death in in vivo and in vitro models of neurological disorders. Acute neuronal death has been attributed to loss of mitochondrial permeability transition coupled with mitochondrial dysfunction. The potential impact of acetaminophen on acute injury from(More)
Here we report our ongoing investigation of the cardiovascular effects of acetaminophen, with emphasis on oxidation-induced canine myocardial dysfunction. The objective of the current study was to investigate whether acetaminophen could attenuate exogenous H(2)O(2)-mediated myocardial dysfunction in vivo. Respiratory, metabolic, and hemodynamic indices such(More)
There is substantial experimental, epidemiological and other evidence that many pesticides in widespread use around the world are immunosuppressive. This poses a potentially serious health risk in populations highly exposed to infectious and parasitic diseases, subject to malnutrition, and inadequately serve by curative health programmes. An expanded(More)
Osteopontin (OPN) is a pleiotropic protein implicated in various inflammatory responses including ischemia-reperfusion (I-R) injury. Two distinct forms of the protein have been identified: an extensively studied secreted form (sOPN) and a less-well-known intracellular form (iOPN). Studies have shown that increased OPN expression parallels the time course of(More)
Mongrel dogs bred for research and weighing 25 +/- 3 kg were used to test the hypothesis that acetaminophen has antiar-rhythmic properties. Only ventricular arrhythmias defined by the Lambeth Conventions were investigated. Dogs were exposed either to 60 mins of regional myocardial ischemia followed by 180 mins of reperfusion (n = 14) or were administered a(More)
Stroke is the leading cause of disability in the United States. It usually occurs from a clot blocking a cerebral artery, resulting in cerebral ischemia and infarction. Few stroke therapeutics are available that definitively improve patient outcome. Acetaminophen is a readily available, inexpensive drug with a good safety profile-properties desirable of a(More)
The critique by Acquavella et al. (1) of the WRI report "Pesticides and the Immune System: The Public Health Risks" (2) represents significant progress, despite its criticisms. The pesticide industry now acknowledges that this issue is an important area for future research and evaluation. This position is very different from the pesticide industry's initial(More)
