Recombinant adeno-associated virus (AAV) vectors are promising in the context of gene therapy because of their ability to mediate efficient gene transfer and stable gene expression. AAV2 uses heparin sulfate as its primary receptor, which is widely expressed on the various tissues and organs. This limits the application of AAV2 in targeting specific(More)
OBJECTIVE To observe the effect of tetrahydroxy stilbene glucoside (TSG) on the behavior of APP695V717I transgenic mouse models and the expression of autophagy-associated proteins Beclin-1 and LC3-II. METHODS Forty 3-month-old APP695V717I transgenic mice were randomized equally into either a TSG group (n = 20) or a model group (n = 20). A normal control(More)
BACKGROUND AND PURPOSE Although recent trials have suggested that stenting is worse than medical therapy for patients with severe symptomatic intracranial atherosclerotic stenosis, it is not clear whether this conclusion applies to a subset of patients with hypoperfusion symptoms. To justify for a new trial in China, we performed a multicenter prospective(More)
Alzheimer’s disease (AD) and vascular dementia (VaD) are the two most dominant forms of dementia in elderly people. Due to the large overlap between AD and VaD in clinical observations, great controversies exist regarding the distinction and connection between these two types of senile dementia. Here for the first time, we resort to the gene expression(More)
Hypermethylation has been shown in the promoter region of the thyroid hormone receptor β1 (TRβ1) gene in several human tumors. However, its role in gastric cancer formation is still unclear. In the study, we analyzed mRNA expression of TRβ1 gene using real-time quantitative PCR (qPCR). A quantitative methylation-specific PCR (Q-MSP) assay was used to(More)
OBJECTIVE To investigate the relationship between the efficacy of interferon beta-1b (INF-β-1b) on relapsing-remitting multiple sclerosis (RRMS) and the Th17 cells in peripheral blood. METHODS Eleven RRMS patients were enrolled and treated with 250 μg INF-β-1b for 6 months. Expanded disability status scale (EDSS) scrore and T2 lesion number on MRI were(More)
BACKGROUND Alzheimer's disease (AD) is characterized with progressive memory loss and severe cognitive impairments, which affect everyday life and human health in the elderly. It is required that an effective and safe protective reagent against AD should be developed. It has been reported that humanin (HN) exerts neuroprotective effects against AD. In this(More)
This paper considers a spectrum-sharing cognitive network in which a secondary user shares spectrum with an existing primary user as long as the interference caused by the secondary user to the primary user is below permissible levels. We investigate the delay quality-of-service (QoS) guaranteed capacity gains with imperfect channel state information (CSI)(More)
