Sensorineural hearing loss (SNHL) is one of the most common sensory defects in humans. Hair cells are vulnerable to various ototoxic insults. Effective prevention of hair cell loss remains an unmet medical need. Apoptotic hair cell death, which involves active regulation of transcription, accounts for the majority of aminoglycoside-induced hair cells loss.(More)
Orphanin FQ (also known as nociceptin) is a 17-amino-acid peptide which acts as a potent endogenous agonist of the orphan opioid receptor-like (ORL1) receptor. Endomorphin-1, a 4-amino-acid peptide discovered recently, is a potent and selective endogenous agonist for the mu-opiate receptor. In the present study, the effect of OFQ or/and endomorphin-1 on the(More)
Chronic stress during critical periods of human fetal brain development is associated with cognitive, behavioral, and mood disorders in later life. Altered glutamate receptor (GluR) expression has been implicated in the pathogenesis of stress-dependent disorders. To test whether prenatal chronic mild stress (PCMS) enhances offspring's vulnerability to(More)
The aim of this study was to investigate whether serotonin (5-hydroxytryptamine, 5-HT) can modulate Na+/K+ pump in rat hippocampal CA1 pyramidal neurons. 5-HT (0.1, 1 mM) showed Na+/K+ pump current (Ip) densities of 0.40 ± 0.04, 0.34 ± 0.03 pA/pF contrast to 0.63 ± 0.04 pA/pF of the control of 0.5 mM strophanthidin (Str), demonstrating 5-HT-induced(More)
The detailed knowledge about the contribution of immunoproteasome to the neuroinflammation in ischemic stroke is still not available. The immunoreactivity of low molecular mass peptide 2 (LMP2) and low molecular mass peptide 7 (LMP7) was evident in the ipsilateral ischemic cerebral cortex and striatum following transient middle cerebral artery occlusion(More)
Calcium channel blockers are used as neuroprotective agents, as glutamate antagonists. However, it has been found that calcium channel blockers may compromise neuronal survival after long-term exposure. To explore the mechanisms of the toxicity of calcium channel blockers on neurons, we studied the morphological characteristics and biochemical changes of(More)
The hippocampal neuronal network oscillation at γ frequency band (γ oscillation) is generated by the precise interaction between interneurons and principle cells. γ oscillation is associated with attention, learning and memory and is impaired in the diseased conditions such as Alzheimer's disease (AD) and schizophrenia. Nicotinic acetylcholine receptor(More)
Dear Editor, Acquired immunodeficiency syndrome (AIDS) caused by human immunodeficiency virus type 1 (HIV-1) infection remains a major public health threat worldwide. 1 Although the antiretroviral therapy (ART) improved the life quality and increased longevity of HIV-infected patients, comorbidities of liver diseases have assumed far greater importance as a(More)
Tessaratoma papillosa (Drury) (Hemiptera: Tessaratomidae) is a serious insect pest of litchi and longan in South China. When disturbed, this insect could release large quantities of disagreeable odorous volatiles from its scent gland. Knowledge on the scent gland and its secretion is crucial for developing the semiochemical methods to manage this pest.(More)
