CNS deletion of Pten in the mouse has revealed its roles in controlling cell size and number, thus providing compelling etiology for macrocephaly and Lhermitte-Duclos disease. PTEN mutations in individuals with autism spectrum disorders (ASD) have also been reported, although a causal link between PTEN and ASD remains unclear. In the present study, we(More)
PTEN (phosphatase and tensin homolog deleted on chromosome ten) is a lipid phosphatase that counteracts the function of phosphatidylinositol-3 kinase (PI3K). Loss of function of PTEN results in constitutive activation of AKT and downstream effectors and correlates with many human cancers, as well as various brain disorders, including macrocephaly, seizures,(More)
Synapse formation requires contact between dendrites and axons. Although this process is often viewed as axon mediated, dendritic filopodia may be actively involved in mediating synaptogenic contact. Although the signaling cues underlying dendritic filopodial motility are mostly unknown, brain-derived neurotrophic factor (BDNF) increases the density of(More)
RATIONALE The selective serotonin uptake inhibitor (SSRI) fluoxetine has been shown to not only increase the extracellular concentrations of serotonin, but also dopamine and norepinephrine extracellular concentrations in rat prefrontal cortex. The effect of other SSRIs on monoamine concentrations in prefrontal cortex has not been thoroughly studied. (More)
Chronic cerebral hypoperfusion has been identified to be a risk factor for cognitive decline in aging, vascular dementia, and Alzheimer's disease. Substantial evidence has shown that chronic cerebral hypoperfusion may cause cognitive impairment, but the underlying neurobiological mechanism is poorly understood so far. In this study, we used a rat model of(More)
Cerebral amyloid-beta protein (Abeta) deposition and associated neuroinflammation and apoptosis are increasingly recognized as an important component leading to cognitive impairment in Alzheimer's disease (AD). Humanin (HN) and its derivative, S14G-HN (HNG), are best known for their ability to suppress neuronal death induced by AD-related insults in vitro.(More)
Oligodendrocyte precursor cells (OPCs) are one of the potential treating tools for multiple sclerosis (MS). Therefore, the cell number and differentiation of OPCs in a demyelinated spinal cord are crucial for improvement of reparative process. In the present study, we investigated whether "Governor Vessel (GV)" electro-acupuncture (EA) could efficiently(More)
There is a great need for new vaccine development against influenza A viruses due to the drawbacks of traditional vaccines that are mainly prepared using embryonated eggs. The main component of the current split influenza A virus vaccine is viral hemagglutinin (HA) which induces a strong antibody-mediated immune response. To develop a modern vaccine against(More)
OBJECTIVES To estimate the average social network size in the general population and the size of HIV key affected populations (KAPs) in Chongqing municipality using the network scale-up method (NSUM). METHODS A general population survey was conducted in 2011 through a multistage random sampling method. Participants aged between 18 and 60 years were(More)
Accumulating evidence shows that mircroRNAs (miRNAs) play a vital role in tumorigenesis. miR-155 is one of the most multifunctional miRNAs whose overexpression has been found to be associated with different types of cancer including breast cancer. To further determine the potential involvement of miR-155 in breast cancer, we evaluated the expression levels(More)
