OBJECTIVE
Cerebrovascular pressure-dependent constriction may involve the smooth muscle production of diacylglycerol, which could facilitate constriction by activating protein kinase C (PKC). A dysfunctional PKC system could promote the loss of pressure-dependent constriction. We attempted to
In the search for novel efficient nNOS-PSD-95 (nitric oxide synthase-postsynaptic density protein-95) uncouplers from natural products for stroke treatment, highly selective surface molecular imprinted polymers based on sandwich structured magnetic mesoporous silica
1. This study investigates the effects of two agonists of the prostanoid EP3-receptor (M&B 28767 and GR 63799X) on the infarct size caused by regional myocardial ischaemia and reperfusion in the anaesthetized rat. 2. One hundred and sixty-seven, male Wistar rats were anaesthetized (thiopentone, 120
BACKGROUND
Dahl salt-sensitive (DSS) rats fed an 8.7% sodium chloride diet from weaning spontaneously developed hypertension and a 50% mortality rate by 5 weeks. Before death the rats exhibited behavioural signs of stroke and disruption of the blood-brain barrier.
OBJECTIVE
To test the hypothesis
Inducible nitric oxide synthase (iNOS) has been implicated as a mediator of cellular toxicity in a variety of neurodegenerative disorders. Nitric oxide, which is generated in high quantities following induction of iNOS, combines with other oxygen radicals to form highly reactive, death-inducing
Activation and injury of microglial cells are involved in a broad range of brain diseases including stroke, brain infection and neurodegenerative diseases. However, there is very little information regarding how to reduce microglial reaction and preserve these cells to provide neuroprotection. Here,
Cerebral ischemia leads to neuronal death for stroke, in which the imbalance between glutamatergic neurons and GABAergic neurons toward neural excitotoxicity is presumably involved. GABAergic neurons are vulnerable to pathological factors and impaired in an early stage of ischemia. The rescue of
The effects of motorcycle exhaust particulate on vasoconstriction were determined using rat thoracic aortas under organ culture conditions treated with organic extracts of motorcycle exhaust particulate from a two-stroke engine. The motorcycle exhaust particulate extract (MEPE) induced a
Increased oxidative stress is a known cause of cardiac dysfunction in animals and patients with diabetes, but the sources of reactive oxygen species [e.g., superoxide anion (O(2)(-))] and the mechanisms underlying O(2)(-) production in diabetic hearts are not clearly understood. Our aim was to
Hypoxia (Hx) is a component of many disease states including stroke. Ischemic stroke occurs when there is a restriction of cerebral blood flow and oxygen to part of the brain. During the ischemic, and subsequent reperfusion phase of stroke, blood-brain barrier (BBB) integrity is lost with tight
Intracerebral hemorrhage (ICH) is a severe cerebrovascular disease with a high incidence, mortality and disability rate. Danhong injection (DHI) is beneficial for ischemic stroke, but is prohibited for ICH due to risk of bleeding. The present study aims to explore the potential therapeutic time
