Previous studies have demonstrated that nicotinamide adenine dinucleotide phosphate (NADPH) oxidase (NOX)-mediated oxidative stress plays a key role in brain injury following cerebral ischemia/reperfusion (I/R) and myosin regulatory light chain kinase (MLCK) has been reported to be involved in NOX activation in lung endothelium. This study was performed to(More)
As autophagy is involved in cell growth, survival, development and death, impaired autophagic flux has been linked to a variety of human pathophysiological processes, including neurodegeneration, cancer, myopathy, cardiovascular and immune-mediated disorders. There is a growing need to identify and quantify the status of autophagic flux in different(More)
AIMS Previously, we have documented that prenatal hypoxia can aggravate the cognitive impairment and Alzheimer's disease (AD) neuropathology in APP(Swe) /PS1(A246E) (APP/PS1) transgenic mice, and valproic acid (VPA) can prevent hypoxia-induced down-regulation of β-amyloid (Aβ) degradation enzyme neprilysin (NEP) in primary neurons. In this study, we have(More)
AIM Ubiquitin-proteasome system (UPS) and autophagosome-lysosome pathway (ALP) are the most important machineries responsible for protein degradation in Parkinson's disease (PD). The aim of this study is to investigate the adaptive alterations in autophagy upon proteasome inhibition in dopaminergic neurons in vitro and in vivo. METHODS Human dopaminergic(More)
In the past decade, enormous efforts have been devoted to understand the genetics and molecular pathogenesis of Alzheimer's disease (AD), which has been transferred into extensive experimental approaches aimed at reversing disease progression. The trend in future AD therapy has been shifted from traditional anti-acetylcholinesterase treatment to multiple(More)
AIMS To evaluate the effectiveness of a new VMAT-2 inhibitor NBI-641449 in controlling hyperkinetic movements of Huntington disease (HD) and to investigate its possible therapeutic effects. METHODS We applied three different doses of NBI-641449 (1, 10, 100 mg/kg/day) for 2 weeks in 4-month-old YAC128 mice and wild-type (WT) mice. Rotarod performance and(More)
Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disorder characterized by the selective loss of motor neurons. Abnormal protein aggregation and impaired protein degradation are believed to contribute to the pathogenesis of this disease. Our previous studies showed that an autophagic flux defect is involved in motor neuron degeneration in(More)
In order to achieve the tactical mission of attacking the target on the appointed direction, the characteristics of maneuver target was analyzed, and a variable structure guidance law with constraints on impact angle, based on the 3-D relative motion model of missile and target, was presented in the point of view of engineering application. The guidance law(More)
BACKGROUND Cordyceps taii, an entomogenous fungus native to south China, is a folk medicine with varieties of pharmacological activities including anticancer effect. To validate the ethnopharmacological claim against cancer, the antitumor and antimetastatic activities of chloroform extract of C. taii (CFCT) were investigated in vivo. METHODS The in vitro(More)
National Student Loans are the use of the financial means to improve the college subsidy policy. State Student Loan is a personal credit loan, but the personal credit assessment system of commercial banks could not make a correct assessment for a college Student’s credit rating because the students have no records about their credit. To avoid the(More)
