OBJECTIVE To explore the effect of Ligustrazine on cells proliferation in cortex and striatum after focal cerebral ischemia in adult rats. METHODS Focal cerebral ischemia was induced by left middle cerebral artery occlusion (MCAO) with suture method. Two hours later, injection of Ligustrazine (80 mg/kg, 1 time/d) was performed peritoneally. Four hours(More)
Gene expression analysis under various conditions using real-time reverse transcription polymerase chain reaction (RT-PCR) needs reliable control genes. Housekeeping genes are commonly used as the control. However, no validated housekeeping gene is available for study of hypoxic neural stem cell culture. To choose appropriate internal control genes, the(More)
OBJECTIVE To investigate the migration and differentiation of ependymal/subventricular zone cells after focal cerebral ischemia in rats, and reveal the origin of the newly generated neural cells in the peri-infarct region. METHODS Normal adult male Sprague Dawley rats weighing 250-350 g were used in this study. Before middle cerebral artery occlusion(More)
Neuronal nitric oxide synthase (nNOS) regulates neurogenesis in the normal developing brain, but the role of nNOS in neurogenesis of the adult ischemic brain remains unclear. The aim of this study was to investigate the temporal and spatial relationship between cell migration from the ependymal/subventricular zone (SVZ) to periinfarction and nNOS expression(More)
The characteristic pathological change of Alzheimer's disease (AD) include deposits of β-amyloid protein (Aβ) in brain, neurofibrillary tangles (NFTs), as well as a few neuronal loss. Evidence shows that Aβ causes calcium influx and induces the cleavage of p35 into p25. Furthermore, the binding of p25 to cyclin-dependent kinase 5 (Cdk5) constitutively(More)
Neuronal nitric oxide synthase (nNOS) regulates neurogenesis in normal developing brain, but the role of nNOS in neurogenesis in the ischemic brain remains unclear. To investigate the temporal and spatial relationship between cell proliferation of the ependymal/subventricular zone (SVZ), a principal neuroproliferative region in the adult brain, and nNOS(More)
Metabotropic glutamate receptors (mGluRs) are expressed in neural progenitor cells (NPCs) and may play important roles in the neurogenesis during embryonic development and adult brain repair following injuries. In the present study, we investigated the expression of metabotropic glutamate receptor 7 (mGluR7) and the possible roles of this receptor in the(More)
BACKGROUND People with physical disability (PWPD) is the largest subgroup of people with disability (PWD) in China, but few studies have been conducted among this vulnerable population. The objective of this study was to investigate the level of quality of life (QoL), self-perceived quality of care and support (QOCS), severity of disability and personal(More)
Collagen triple helix repeat-containing 1 (CTHRC1) is aberrantly overexpressed in multiple malignant tumors. However, the expression characteristics and function of CTHRC1 in epithelial ovarian cancer (EOC) remain unclear. We found that CTHRC1 expression was up-regulated in the paraffin-embedded EOC tissues compared to borderline or benign tumor tissues.(More)
OBJECTIVE Efforts have been made by tissue engineers to create a permissive environment for neural regeneration, and to enhance the efficiency of neural stem cell (NSC) transplantation. However, to acquire sufficient number of seed cells on the material appears to be the main obstacle to constructing functional transplantable NSC-biomaterial complexes. A(More)
