In this study, we investigated the effects and mechanism of quercetin preconditioning on anti-myocardial ischemia reperfusion (IR) injuries in vivo. Meanwhile, their potential anti-oxidative stress and anti-inflammation effect were assessed. SD rats were orally given quercetin 250 mg/kg. Myocardium apoptosis was determined with TUNEL staining. The(More)
The precedence e€ect, though a topic of continuous theoretical interest in hearing research, so far cannot be predicted explicitly by a model. Zurek (1987) reviewed the precedence e€ect and gave a general structure for the model of the precedence e€ect. However, it is still not clear how the inhibition of localization is generated. This paper proposes a(More)
Dengue virus (DENV) remains a major public health threat because no vaccine or drugs are available for the prevention and treatment of DENV infection, and the immunopathogenesis mechanisms of DENV infection are not fully understood. Cytotoxic molecules, such as granzyme B (GrzB), may be necessary to control viral infections. However, the exact role of GrzB(More)
Extracellular Ca(2+) influx has been suggested to play a role in ethanol-induced hepatocyte apoptosis and necrosis. Previous studies indicated that store-operated Ca(2+) entry (SOCE) was involved in liver injury induced by ethanol in HepG2 cells. However, the mechanisms underlying liver injury caused by SOCE remain unclear. We aimed to investigate the(More)
Severe dengue is more likely found during secondary heterologous dengue virus (DENV) infection or primary infection of infants born to dengue-immune mothers and led to the hypothesis of antibody-dependent enhancement (ADE). It has been reported that pre-membrane (prM)-reactive antibodies do not efficiently neutralize DENV infection but instead potently(More)

AIMS Hyperglycemia leads to cytotoxicity in the heart. Although theories were postulated for glucose toxicity-induced cardiomyocyte dysfunction including oxidative stress, the mechanism involved still remains unclear. Recent evidence has depicted a role of protein kinase C (PKC) in diabetic complications while high concentrations of glucose stimulate PKC.(More)
Human epididymis protein 4 (HE4) is one of the best-known tumor markers for ovarian cancer (OC). Emerging evidence indicates that the evaluation of serum HE4 (S-HE4) levels may be problematic when patients have chronic kidney disease (CKD). Assaying urine for HE4 levels is non-invasive alternative for the diagnosis of OC. However, whether the combined(More)
Sustained activation of hepatic stellate cells (HSCs) leads to liver fibrosis. Autophagy fuels the activation of HSCs by generation of ATP. Our previous research demonstrated an inhibitory effect of dimethyl α-ketoglutarate (DMKG) on HSCs activation in vitro. In the current study, we demonstrated that DMKG reduced CCl4-induced liver fibrosis in Wistar rats.(More)
The reactive oxygen species(ROS)/mitogen-activated protein kinase (MAPK) destroyed autophagy and the reactive oxygen species/mitogen-activated protein kinase (MAPK) pathway are considered closely related to ethanol-induced hepatocellular injury. Previous work indicated that corosolic acid, the natural extracts of leaves of the banaba tree, Lagerstroemia(More)
