Acute kidney injury (AKI) is a common complication following orthotopic liver transplantation (OLT) that evidently affects prognosis. However, no effective treatment exists for AKI. The aim of the present study was to elucidate whether ulinastatin application during OLT in humans can reduce kidney damage and improve renal function. In addition, the(More)
Adhesion between circulating monocytes and vascular endothelial cells is a key initiator of atherosclerosis. In our previous studies, it was demonstrated that the expression of connexin (Cx)43 in monocytes modulates cell adhesion, however, the effects of the expression of Cx43 in endothelial cells remains to be elucidated. Therefore, the present study(More)
AIMS Both mast cells and oxidative stress are involved in acute lung injury (ALI) induced by intestinal ischemia-reperfusion (IIR). The aim of this study was to investigate whether propofol could improve IIR-induced ALI through inhibiting their interaction. MAIN METHODS Repetitive, brief IIR or IIR+compound 48/80 was performed in adult Sprague-Dawley rats(More)
Cisplatin [cis-diamminedichloroplatinum(II)]/oxaliplatin [1,2-diamminocyclohexane(trans-1)oxolatoplatinum(II)] toxicity is enhanced by functional gap junctions between treated cells, implying that inhibition of gap junctions may decrease cytotoxic activity of these platinum-based agents. This study investigates the effect of gap junction modulation by(More)
Adhesion of circulating monocytes to vascular endothelial cells is a crucial event in development of vascular inflammatory conditions, including atherosclerosis. We investigated the roles of connexin43 (Cx43) and ATP release on monocyte-endothelial adhesion. Cx43 function and expression were manipulated by connexin channel inhibitors, overexpression and(More)
BACKGROUND Postliver transplantation acute kidney injury (AKI) severely affects patient survival, whereas the mechanism is unclear and effective therapy is lacking. The authors postulated that reperfusion induced enhancement of connexin32 (Cx32) gap junction plays a critical role in mediating postliver transplantation AKI and that pretreatment/precondition(More)
BACKGROUND Nuclear factor-E2-related factor 2 (Nrf2)-mediated antioxidant response is the main protective system of graft-liver against ischemia-reperfusion injury after liver transplantation. Propofol is considered to confer protective effects on different organs; thus, we explored the possibility that whether propofol could attenuate graft-liver injury in(More)
BACKGROUND General anesthetics (e.g., propofol) influence the therapeutic activity of intraoperative radiotherapy but the mechanism of the effects is largely unknown. It has been reported that propofol inhibits gap junction (GJ) function briefly, and a functional GJ enhances the efficacy of radiotherapy in some cancer cells. Yet the mechanisms underlying(More)
AIMS The α2-adrenoceptor inducer dexmedetomidine (Dex) provides renoprotection against ischemia/reperfusion (I/R) injury, but the mechanism of this effect is largely unknown. The present study investigated the effect of Dex on apoptosis induced by hypoxia/reoxygenation (H/R) and the relationship between this effect and gap junction intercellular(More)
Acute lung injury (ALI) induced by liver transplantation is detrimental to patient survival, and therapeutic strategies remain limited. Thus, the protective effects of propofol, a commonly used anesthetic with antioxidative and anti‑inflammatory properties, were investigated in the present study on ALI induced by orthotopic autologous liver transplantation(More)
