A map of protein-protein interactions provides valuable insight into the cellular function and machinery of a proteome. By measuring the similarity between two Gene Ontology (GO) terms with a relative specificity semantic relation, here, we proposed a new method of reconstructing a yeast protein-protein interaction map that is solely based on the GO(More)
OBJECTIVE There has been no large-scale survey of schizophrenia in China involving both rural and urban areas using standardized assessment tools and diagnostic criteria. This study aimed to determine the lifetime prevalence of schizophrenia and its socio-demographic correlates in Beijing, China. METHODS A total of 5926 subjects were randomly selected in(More)
Z-ligustilide (LIG), the main lipophilic component of Radix Angelica sinensis, has been shown to protect against brain ischemic damage in rodents by oral and intra-peritoneal treatments. The present study aimed to confirm the therapeutic effect of LIG administered intravenously on 2h middle cerebral artery occlusion (MCAO) and 22 h reperfusion injury in(More)
Astaxanthin (AST) is a powerful antioxidant that occurs naturally in a wide variety of living organisms. Much experimental evidence has proved that AST has the function of eliminating oxygen free radicals and can protect organisms from oxidative damage. The present study was carried out to further investigate the neuroprotective effect of AST on oxidative(More)
Pulmonary fibrosis is an irreversible chronic progressive fibroproliferative lung disease, which usually has a poor prognosis. Previous studies have confirmed that the transplantation of bone marrow mesenchymal stem cells (MSCs) significantly reduces lung damage in a number of animal models. However, the underlying mechanism involved in this process remains(More)
Hypoxia-inducible factor-1 (HIF-1) is a master regulator of cellular and systemic oxygen homeostasis. Recently, we demonstrated that ginkgolides, the main constituents of the non-flavone fraction of the standardized Ginkgo biloba (Ginkgoaceae) extract EGb 761, have a significant protective role against chemical and physical hypoxia-induced injury in neurons(More)
Many studies indicate that impairment in insulin signaling leads to learning and memory deficits. However, previous studies failed to establish a clear role of insulin in long-term potentiation (LTP), the best cellular model of memory formation. Here we show that while insulin pretreatment did not affect LTP magnitude in the adult rat hippocampus, it(More)
ETHNOPHARMACOLOGICAL RELEVANCE Ligustilide (LIG), a main lipophilic component of Danggui (Chinese Angelica root, Radix Angelica sinensis) which is a popular used herb to treat menstrual disorders in traditional chinese medicine, has been reported to possess some neuroprotective effects on permanent focal ischemia and transient forebrain ischemia. AIM OF(More)
Although ischemic preconditioning (IP) can provide powerful protection on brain against ischemic insult, it is rarely used in clinic to prevent the occurrence of ischemic stroke because of safety concerns. It is therefore necessary to seek the safer stimuli to initiate pharmacological preconditioning. Our previous work demonstrated that ginkgolide B (GB)(More)
Ischaemic preconditioning (IP) has been reported to protect the brain against subsequent lethal ischaemia, but it has not been used clinically to prevent ischaemic injury because of safety concerns. The aim of the present study was to see whether Ginkgolide B (GB) is capable of preconditioning as IP to protect neurons against ischaemic injury; if so, which(More)
