Matrix metalloproteinases (MMPs) mediate tissue injury during acute stroke. Clinical data show that elevated MMPs in plasma of stroke patients may correlate with outcomes, suggesting its use as a biomarker. MMP-9 signal has also been detected in clinical stroke brain tissue samples. Because tissue
"Baicalin, a major flavonoid compound isolated from the dry roots of Scutellaria baicalensis Georgi, has been shown to be neuroprotective after ischemic brain injury. However, little is known about its effects on brain injury following intracerebral hemorrhage (ICH). In this study, we evaluated the
The calicivirus rabbit haemorrhagic disease virus (RHDV) possesses a 3C-like protease which processes the RHDV polyprotein. In order to monitor the proteolytic activity of the RHDV 3C-like protease on its putative target sequences, i.e. the 10 EG dipeptide bonds distributed along the large
The substrate specificity of a hemorrhagic protease derived from habu (Trimeresurus flavoviridis) venom was determined using oxidized insulin-B chain as a substrate. The enzyme was shown to be a fairly specific protease; it cleaved the substrate essentially at two positions, His10-Leu11 and
In July 1996 the Food and Drug Administration (FDA) alerted healthcare providers about 15 case reports of spontaneous bleeding episodes in HIV-positive haemophiliacs taking HIV protease inhibitors. In order to characterize the bleeding associated with HIV protease inhibitor therapy, the FDA's
Infectious viruses bind more tenaciously to the zonae pellucidae of in vitro produced bovine embryos than to zonae of in vivo derived embryos. Currently, the International Embryo Transfer Society recommends that all in vivo derived embryos be subjected to a rigorous washing procedure in combination
Seventeen HIV-positive patients with congenital haemophilia, one with von Willebrand's disease, and one with acquired haemophilia in remission, were treated with antiretroviral protease inhibitors. Clear increases in the frequency of bleeds or changes in the bleeding pattern were documented in 10
In order to obtain basic data on the effect of broad-spectrum protease inhibitor against local symptoms of Viperidae snake envenomation, inhibitory capacity of rat murinoglobulin on local hemorrhagic and edematogenic activities of venoms from Crotalus atrox, Bothrops jararaca, Lachesis muta muta,
OBJECTIVE
To investigate the effect of intraluminal administration of ulinastatin (a protease inhibitor) in the intestine on intestinal inflammation in rats with hemorrhagic shock.
METHODS
Twenty-eight Wistar rats were randomized into control group (A), intestinal saline perfusion group (B),
OBJECTIVE
Plasma serine protease cascade, including the complement system and thrombin, is activated in the subarachnoid space during the acute phase after subarachnoid hemorrhage (SAH). To examine the effect of protease cascade-based inflammation and subsequent vascular repair in the development of
OBJECTIVE
Although aprotinin has been widely used to reduce perioperative blood loss after cardiopulmonary bypass, recent concerns have led to its withdrawal. This study investigated effects of the novel synthetic serine protease inhibitors CU-2010 and CU-2020 on blood loss, coagulation parameters,
OBJECTIVE
This study examines the role of thrombin's protease-activated receptor (PAR)-1, PAR-4 in mediating cyclooxygenase-2 and mammalian target of rapamycin after germinal matrix hemorrhage.
METHODS
Germinal matrix hemorrhage was induced by intraparenchymal infusion of bacterial collagenase into
OBJECTIVE
To assess the relationship between protease-activated receptor 1 (PAR1) expression in the basilar artery and cerebral vasospasm (CVS) in a rat model of subarachnoid hemorrhage (SAH).
METHODS
Twenty-four SD rats were randomized into normal control group, SAH 3-days group, SAH 5-days group
BACKGROUND
Recognition of the limitations of standard crystalloid resuscitation has led to the search for alternative resuscitation strategies that might better limit the development of trauma-hemorrhage-induced organ dysfunction and systemic inflammation. Thus, the goal of this study was to compare
Hypercoagulability is known to occur in the early phase of hemorrhagic shock. The prolongation of excessive clot formation after recovery from a shock state leads to the formation of microthrombi or disseminated intravascular coagulation which disturbs microcirculation, damaging organ function. The
