ischemia/protease

Endothelial dysfunction is an essential deleterious modulator of ischaemia/reperfusion (I/R) injury. Secretory leukocyte protease inhibitor (SLPI) has demonstrated myocardial protection in cardiac transplantation; however, the effect of SLPI in endothelial I/R injury remains unexplored. In the

Vascular endothelial cell (EC)-derived factors play an important role in endothelial-cardiomyocyte crosstalk and could save cardiomyocytes (CMs) from injury. The manipulation of endothelial cells to secrete protective factors could enhance cardioprotection. Secretory leukocyte protease inhibitor

One of the major causes of cardiac cell death during myocardial ischemia is the oversecretion of protease enzymes surrounding the ischemic tissue. Therefore, inhibition of the protease activity could be an alternative strategy for preventing the expansion of the injured area. In the present study,

Various procedures such as angioplasty, thrombolytic therapy, coronary bypass surgery, and cardiac transplantation are invariably associated with ischemia-reperfusion (I/R) injury. Impaired recovery of cardiac function due to I/R injury is considered to be a consequence of the occurrence of both

We investigated the role of secretory leukocyte protease inhibitor (SLPI) in ischemia/reperfusion injury in cardiac transplantation. SLPI-/- mouse hearts and wild-type (WT) controls were transplanted immediately or after 10 h of cold ischemia (CI). Recombinant SLPI (rSLPI) was added to the

OBJECTIVE To investigate whether gabexate mesilate, a synthetic protease inhibitor with anticoagulant properties, prevents hepatic damage by inhibiting leukocyte activation, we examined its effect on ischemia/reperfusion injury of rat liver in which activated leukocytes play a critical

Recent in vitro studies indicate an involvement of members of the interleukin-1beta converting enzyme (ICE) family of proteases in programmed neuronal cell death. Cell death of hippocampal neurons in animal models of cerebral ischemia and epilepsy shows morphological features of apoptosis and can be

Plasma endothelin (ET) is increased in association with myocardial infarction. The aim of the present study was to get insight into the mechanisms behind this ischemia-induced increase in plasma ET. Since granulocytes increase ET production in vitro, we examined to what extent inhibition of

The current study was done to evaluate the effects of short term (60 minutes) pancreatic biliary duct obstruction (PBDO) with intraductal hypertension (IDH) stimulated by secretin (0.2 clinical unit per kilogram per hour) and caerulein (0.2 microgram per kilogram per hour) plus 30 minutes of

A pronounced hippocampal expression of the Protease-activated Receptor 4 (PAR4) has recently been shown. In the current study the authors define the PAR4-associated sub-cellular structures and the influence of global ischaemia on the expression of PAR4. For that purpose the authors performed double

BACKGROUND Kidneys from non-heart-beating donors are associated with delayed graft function and a high rejection rate due to the long period of warm ischemia. Gabexate mesilate (GM), a synthetic serine protease inhibitor, has been shown to improve organ function by suppressing cytokine activity and

Degeneration or survival of cerebral tissue after ischemic injury depends on the source, intensity, and duration of the insult. In the model of focal ischemia, reduced blood flow results in a cascade of pathophysiologic events, including inflammation, excitotoxicity, and platelet activation at the

Delayed neuronal death after transient cerebral ischemia may be mediated, in part, by the induction of apoptosis-regulatory gene products. Caspase-3 is a newly characterized mammalian cysteine protease that promotes cell death during brain development, in neuronal cultures, and in other cell types

BACKGROUND The severity of ischemia and reperfusion (I/R) injury is an important determinant of patient outcome in hepatic surgery. The aim of this study was to investigate the efficacy of a protease inhibitor in alleviating I/R injury to human liver in the setting of hepatectomy under intermittent

This experimental study was designed to determine if caspase-3-like protease is activated during a short period of ischemia - reperfusion (I-R) that did not induce apoptosis, and whether protease-3-protease inhibitor could prevent myocardial I-R injury, especially necrotic cell death. The subjects
