Diabetes increases the risk of Alzheimer's disease (AD). The pathological hallmarks for AD brains are extracellular amyloid plaques formed by β-amyloid peptide (Aβ) and intracellular neurofibrillary tangles consisting of hyperphosphorylated tau protein. This study was designed to determine AD-like brain changes in mice modeling for type 2 diabetes. The(More)
A pre-exposure to isoflurane reduces ischemic brain injury in rodents (isoflurane preconditioning). This neuroprotection has acute and delayed phases. Our previous in vitro studies suggest that the acute phase may involve excitatory amino acid transporters (EAATs). We determine whether this protection involves EAAT3, the major neuronal EAAT. Adult male(More)
Petal colour is one of the major characteristics that determine the ornamental value of lotus. To assess the contribution of different flavonoids to this character, composition and content of anthocyanins, flavones and flavonols were analysed through high performance liquid chromatography coupled with photodiode array detection tandem electrospray(More)
BACKGROUND It has been reported that sevoflurane preconditioning can induce neuroprotection, the mechanisms of which, however, are poorly elucidated. We designed the present study to examine the hypothesis that sevoflurane preconditioning could reduce cerebral ischemia- reperfusion injury through up-regulating antioxidant enzyme activities before ischemic(More)
Application of isoflurane, a volatile anesthetic, after brain ischemia can reduce ischemic brain injury in rodents (isoflurane postconditioning). This study is designed to determine whether isoflurane postconditioning improves long-term neurological outcome after focal brain ischemia and whether this protection is mediated by attenuating neuroinflammation.(More)
The neuroprotective properties for certain medical gases have been observed for decades, leading to extensive research that has been widely reported and continues to garner interest. Common gases including oxygen, hydrogen, carbon dioxide and nitric oxide, volatile anesthetics such as isoflurane, sevoflurane, halothane, enflurane and desflurane,(More)
Delayed remote ischemic postconditioning (DRIPost) has been shown to protect the rat brain from ischemic injury. However, extremely short therapeutic time windows hinder its translational use and the mechanism of action remains elusive. Because opening of the mitochondria K(ATP) channel is crucial for cell apoptosis, we hypothesized that the neuroprotective(More)
Gastrodin (GAS), an active constituent of the Chinese herbal medicine Tianma, has anti-oxidant and anti-inflammation activities but its protective effect to the prevention of neurotoxicity induced by ischemic stroke is unclear. In the present study, middle cerebral artery occlusion (MCAO) was used to establish a mice ischemic stroke model. Infarct volume(More)
Trans-sodium crocetinate (TSC) is a novel synthetic carotenoid compound that improves diffusion of small molecules, including oxygen, in solutions. TSC provides neuroprotection in healthy rats and rabbits. This study seeks to determine whether TSC is neuroprotective in obese mice. Sixteen-week-old CD-1 male mice that had been fed a high-fat diet for 10(More)
BACKGROUND Signal transducer and activator of transcription 3 (STAT3) activation in ischemic brain has been verified. However, the mechanism and the role of STAT3 activation after cerebral ischemia-reperfusion are poorly elucidated. In the present study, we sought to test the hypothesis that STAT3 activation after cerebral ischemia-reperfusion was related(More)
