Accumulating evidence suggests that endogenous dopamine may act as a neurotoxin and thereby participate in the pathophysiology of Parkinson's disease (PD). Cyclooxygenase-2 (COX-2) has been implicated in the pathogenesis of PD due to its ability to generate reactive oxygen species (ROS). Inhibition of COX-2 leads to neuroprotection by preventing the(More)
Key Words: hemorrhagic shock ⅐ heart ⅐ estrogen receptor ⅐ mi-tochondria Despite numerous advances in intensive care medicine , ischemia/reperfusion injury, sepsis, and organ dysfunction leading to multiple organ failure remain the major cause of death in trauma patients as well as in patients following major surgery (1– 8). Previous studies have shown that(More)
BACKGROUND Although the role of autophagy in sepsis has been characterized in several organs, its role in the adaptive immune system remains to be ascertained. This study aimed to investigate the role of autophagy in sepsis-induced T cell apoptosis and immunosuppression, using knockout mice with T cell specific deletion of autophagy essential gene Atg7.

Men exhibit a worse survival rate than premenopausal women after intracerebral hemorrhage (ICH), however, no sex-specific management has been concerned. In a rat model involving infusion of ferrous citrate (FC) that simulates iron accumulation after hemorrhage, a higher degree of autophagy associated with higher injury severity was observed in striatum of(More)
Although previous studies have shown that flutamide improves cardiovascular functions following trauma-hemorrhage (T-H), the mechanisms responsible for the salutary effect remain unknown. We hypothesized that flutamide mediates its beneficial effects via an estrogen-dependent pathway through upregulation of peroxisome proliferator-activated receptor(More)
