Recent studies show that AMPA receptor (-R) trafficking is important in synaptic plasticity. However, the signaling controlling this trafficking is poorly understood. Small GTPases have diverse neuronal functions and their perturbation is responsible for several mental disorders. Here, we examine the small GTPases Ras and Rap in the postsynaptic signaling(More)
Traumatic brain injury (TBI) is a serious insult that frequently leads to neurological dysfunction or death. Silent information regulator family protein 1 (SIRT1), as the founding member of nicotinamide adenine dinucleotide (NAD)-dependent deacetylases, has recently been demonstrated to have neuroprotective effect in several models of neurodegenerative(More)
BACKGROUND Mechanism of sevoflurane preconditioning-induced cerebral ischemic tolerance is unclear. This study investigates the role of N-myc downstream-regulated gene-2 (NDRG2) in the neuroprotection of sevoflurane preconditioning in ischemic model both in vivo and in vitro. METHODS At 2 h after sevoflurane (2%) preconditioning for 1 h, rats were(More)
In an attempt to analyze the chemical characterization of oil residues and examine the suitability of chemical fingerprinting methods in oil spill investigations, multiple parameters sensitive to both sources and degree of weathering were used to characterize oil residues from "7-16" Dalian oil spill, China. Oil residues collected 90 days to 120 days after(More)
Oxidative stress-induced cell death is common in many neurological diseases. However, the role of poly(ADP-ribose) polymerase-1-induced cell death (parthanatos) has not been fully elucidated. Here, we found that hydrogen peroxide (H2O2) could lead to PARP-1 activation and apoptosis-inducing factor nuclear translocation in a concentration dependent manner.(More)
An accumulation of milk fat globule EGF-8 protein (MFG-E8) occurs within the context of arterial wall inflammatory remodeling during aging, hypertension, diabetes mellitus, or atherosclerosis. MFG-E8 induces VSMC invasion, but whether it affects VSMC proliferation, a salient feature of arterial inflammation, is unknown. Here, we show that in the rat(More)
AIMS/HYPOTHESIS More than 90% of Chinese familial early-onset type 2 diabetes mellitus is genetically unexplained. To investigate the molecular aetiology, we identified and characterised whether mutations in the KCNJ11 gene are responsible for these families. METHODS KCNJ11 mutations were screened for 96 familial early-onset type 2 diabetic probands and(More)
The preproghrelin (GHRL) Leu72Met polymorphism (rs 696217) is associated with obesity, reduced glucose-induced insulin secretion in healthy or diabetic subjects, and reduced serum creatinine (Scr) levels in type 2 diabetes. We evaluated the association of the Leu72Met polymorphism with measures of insulin sensitivity in non-diabetic control individuals and(More)
The purpose of this study was to develop an in situ forming SAIB (sucrose acetate isobutyrate)-PLGA (poly (d, lactide-co-glycolide)) mixture matrix depot for sustained release of risperidone. The factors affecting the risperidone release kinetics were investigated to obtain further insight into the drug release mechanisms. The burst release in vitro was(More)
Oxidative stress-induced cell damage is involved in many neurological diseases. Homer protein, as an important scaffold protein at postsynaptic density, regulates synaptic structure and function. Here, we reported that hydrogen peroxide (H(2)O(2)) induced the expression of Homer 1a. Down-regulation of Homer 1a with a specific small interfering RNA (siRNA)(More)
