The marked increase of amyloid-β (Aβ) peptide after traumatic brain injury (TBI), confers a risk factor for Alzheimer's disease (AD) in patients' later life. Nerve growth factor (NGF) is great potential to repair brain injury. But its clinical application is limited because of lacking feasible methods for delivering NGF into brain. This study investigated(More)
We investigated the changes and the molecular mechanisms of cerebral vascular damage after stroke in type-2 diabetic (T2DM) mice. Adult male db/db T2DM and wild-type (WT) mice were subjected to transient middle cerebral artery occlusion (MCAo) and sacrificed 24 hours after MCAo. T2DM-mice exhibited significantly increased blood glucose, brain hemorrhagic(More)
BACKGROUND AND PURPOSE Cell therapy with bone marrow stromal cells (BMSCs) improves functional recovery after stroke in nondiabetic rats. However, its effect on diabetics with stroke is unknown. This study investigated the effect of BMSCs on stroke outcome in Type 1 diabetic (T1DM) rats. METHODS T1DM was induced in adult male Wistar rats by injecting(More)
(-)-Epigallocatechin-3-gallate (EGCG), the major polyphenolic component of green tea, has anti-inflammatory and antioxidant properties and provides neuroprotection against central nervous system diseases. Yet, it is not known whether EGCG may be neuroprotective against intracerebral hemorrhage. In this study, we used a simplified in-vitro model of thrombin(More)
High-mobility group box 1 (HMGB1), a ligand of receptor for advanced glycation endproducts (RAGE), functions as a proinflammatory factor. It is mainly involved in inflammatory activation and contributes to the initiation and progression of stroke. By using a model of transient middle cerebral artery occlusion (MCAo) in type 2 diabetic rats, we investigated(More)
To investigate whether the ROCK pathway is involved in thrombin-induced microglial inflammatory response, thrombin-induced microglia were pretreated with the thrombin inhibitor argatroban or a ROCK inhibitor Y-27632. Microglial inflammatory response was evaluated by phagocytosis of fluorescein labeled latex beads analyses and inflammatory mediators'(More)
We aimed to investigate the association between plasma homocysteine and obstructive sleep apnoea (OSA) syndrome in patients with ischaemic stroke. A total of 102 patients with ischaemic stroke were classified into four OSA groups based on their apnoea-hypopnoea index (AHI): absent (AHI < 5/hour); mild (5-14/hour); moderate (15-30/hour); and severe (>(More)
We investigated the changes and the molecular mechanisms of cerebral vascular damage and tested the therapeutic effects of Niaspan in type-1 streptozotocin induced diabetic (T1DM) rats after stroke. T1DM-rats were subjected to transient middle cerebral artery occlusion (MCAo) and treated without or with Niaspan. Non-streptozotocin rats (WT) were also(More)
Migraine is a debilitating condition characterized by a multi-factorial and polygenic mode of inheritance. Tumor necrosis factor alpha (TNF-α), a pro-inflammatory cytokine, has been implicated in the pathophysiological mechanisms of migraine. The aim of this study was to investigate whether TNF receptor superfamily member 1b gene (TNFRSF1B) polymorphism(More)
Activated Metabotropic glutamate receptors 5(mGluR5) exhibits protective effects against ischemic brain damage, but the underlying mechanisms are not clearly known. Brain-derived neurotrophic factor (BDNF), as a valuable member of neurotrophic factor family, exerts its protection by combining with its high-affinity receptor tyrosine protein kinase B (TrkB).(More)
