"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

Brain edema is one of the most frequent and serious complications of intracerebral hemorrhage (ICH), but how the ICH cause brain edema is unknown. Our studies were designed to investigate the regulation and distribution of protease nexin-1 (PN-1), thrombin and aquaporin-4 (AQP-4) in brain edema

Thrombin plays an important role in brain injuries associated with intracerebral hemorrhage (ICH). The protease-activated receptor (PAR)-1 is responsible for the vast majority of the thrombin's cellular activation functions. We tested the hypothesis that thrombin-induced brain damage after ICH, at

Thrombin causes blood-brain barrier disruption, and this study examined whether thrombin can cause brain hemorrhage through protease-activated receptor-1 (PAR-1). Male wild type and PAR-1 knockout mice had an intracerebral injection of thrombin or saline. Mice then underwent serial T2 magnetic

Our previous studies have demonstrated that thrombin plays an important role in intracerebral hemorrhage (ICH)-induced brain injury and edema formation. We, therefore, examined whether nafamostat mesilate (FUT), a serine protease inhibitor, can reduce ICH-induced brain injury. Anesthetized male

The present study investigated the role of thrombin in the expression of protease-activated receptor-1 (PAR-1), and the effect of argatroban (Arg) a direct thrombin inhibitor, on PAR-1 expression in perihematomal tissue with intracerebral hemorrhage (ICH). For these experiments 90 rats were divided

OBJECTIVE
To investigate the protective effect and mechanism of baicalin on nerve tissue in rat with intracerebral hemorrhage (ICH).
METHODS
Rats were randomly divided into five groups: the sham-operated group, the ICH model group, and the three baicalin treated groups treated respectively with

OBJECTIVE
To study the dynamic expression of protease-activated receptor-1(PAR-1) after acute intracerebral hemorrhage (ICH) and the influence of Naomai capsule (NMC II) on the expression in rats.
METHODS
72 rats were randomly divided into 9 groups (n = 8 in each group). They were normal group, ICH

Ubiquitinating enzymes catalyze protein ubiquitination, a reversible process countered by deubiquitinating enzyme (DUB) action. Ubiquitin-specific protease 4 (USP4) is a member of the ubiquitin-specific protease (USP) family of DUBs that has a role in spliceosome regulation. In the present study, we

Polarized microglia play a dual (beneficial/detrimental) role in neurological diseases. However, the status and the factors that modulate microglia polarization in intracerebral hemorrhage (ICH) remain unclear. In the present study, we investigated the role of protease-activated receptor-1 (PAR-1, a

Hemorrhagic meningitis is a fatal complication of anthrax, but its pathogenesis remains poorly understood. The present study examined the role of B. anthracis-secreted metalloprotease InhA on monolayer integrity and permeability of human brain microvasculature endothelial cells (HBMECs) which

It has been demonstrated that Src could modulate NMDA receptor, and PAR1 could also affect NMDAR signaling. However, whether PAR1 could regulate NMDAR through Src under ICH has not yet been investigated. In this study, we demonstrated the role of Src-PSD95-GluN2A signaling cascades in rat ICH model

Previously we showed that expansion of intracerebral hemorrhage (ICH) into the internal capsule greatly aggravated neurological symptoms in mice. Here we examined ICH-associated events in the internal capsule with relation to neurological dysfunction. Corticospinal axons labeled by biotinylated

Although herpes simplex virus type 1 (HSV-1) is the most common cause of sporadic encephalitis in immunocompetent adults, it is an unusual cause of encephalitis in patients with HIV/AIDS. We report the case of a 56-year-old man with recently diagnosed HIV infection who presented with subacute mental
