The existence of large-conductance Ca(2+)-activated K(+) (BK) channels in substantia nigra pars compacta (SNc) has been a matter of debate. Using the patch-clamp technique in the inside-out configuration, we have recorded BK channel currents in SNc dopaminergic neurons. The channel has a conductance of 301 pS with a slight inward rectification and is both(More)
Redox activity is an important property of living cells, and decreases in redox activity are likely to be an upstream event in ischemic brain injuries. In this study, immediate changes in redox activity caused by ischemic injury were investigated in oxygen-glucose deprivation (OGD) treated mouse brain tissue. Adult mouse brain slices were subjected to 10(More)
Introduction The abnormal amyloid β (Aβ) accumulation and Aβ-related neural network dysfunction are considered central to the pathogenesis of Alzheimer's disease (AD) at the early stage. Deep-brain reachable low field magnetic stimulation (DMS), a novel noninvasive approach that was designed to intervene the network activity in brains, has been found to(More)
Electroacupuncture (EA) has been reported to alleviate motor deficits in Parkinson's disease (PD) patients, and PD animal models. However, the mechanisms by which EA improves motor function have not been investigated. We have employed a 6-hydroxydopamine (6-OHDA) unilateral injection induced PD model to investigate whether EA alters protein expression in(More)
OBJECTIVE To evaluate the effect of serum albumin on prognosis and the power of albumin adding information to NT-proBNP in a Chinese cohort of heart failure. DESIGN AND METHODS 385 consecutive patients (male vs. female: 292 vs. 93; mean age: 54.89±14.41years; NYHA classes II-V) admitted for heart failure exacerbation with LVEF≤45% were enrolled, and(More)
As the population ages, an increasing number of people suffer from age-related cognitive impairment. However, the mechanisms underlying this process remain unclear. Here, we found that S-nitrosoglutathione reductase (GSNOR), the key enzyme that metabolizes intracellular nitric oxide (NO) and regulates S-nitrosation, was significantly increased in the(More)
Postconditioning prevents cardiomyocytes from ischemia/reperfusion-induced apoptosis. However, little is known about the molecular mechanisms that mediate the cardioprotective effect of postconditioning. Here, we hypothesized that postconditioning targeted p53 upregulated modulator of apoptosis (PUMA) to protect cardiomyocytes against endoplasmic reticulum(More)
Alcohol dehydrogenase 5 (ADH5) is a conserved enzyme for alcohol and aldehyde metabolism in mammals. Despite dynamic expression throughout neurogenesis, its role in neuronal development remains unknown. Here we present the first evidence that ADH5 is a negative regulator of neuronal differentiation. Gene expression analyses identify a constant reduction of(More)
Whether large conductance Ca(2+)-activated potassium (BK) channels are present in the substantia nigra pars reticulata (SNr) is a matter of debate. Using the patch-clamp technique, we examined the functional expression of BK channels in neurons of the SNr and showed that the channels were activated or inhibited by internal high-energy phosphates (IHEPs) at(More)
