BACKGROUND The aetiology of Alzheimer's disease (AD) is believed to involve environmental exposure and genetic susceptibility. The aim of our present systematic review and meta-analysis was to roundly evaluate the association between AD and its modifiable risk factors. METHODS We systematically searched PubMed and the Cochrane Database of Systematic(More)
OBJECTIVE We sought to identify the risk factors for predicting the progression from mild cognitive impairment (MCI) to Alzheimer's disease (AD). METHODS We searched 6 electronic databases for cohort studies published from January 1966 to March 2015. Eligible studies were required to be relevant to the subject and provide sufficient data for our needs. (More)
Educational level has been regarded as one of the most widely accepted risk factors in the epidemiological studies for dementia, despite with discordant qualitative results. However, the dose-response relation between education and incident dementia was still unknown. To quantitatively evaluate the association between exposure level to high and low(More)
ABCA7 gene has been identified as a strong genetic locus for Alzheimer's disease (AD) susceptibility in genome wide association studies (GWAS). However, the possible roles of ABCA7 variants in AD pathology were not specifically assessed. Using tagger methods, we extracted 15 targeted ABCA7 loci to investigate their associations with cerebrospinal fluid(More)
ATP-binding cassette A7 (ABCA7) gene has recently been identified as a strong genetic locus associated with late-onset Alzheimer’s disease (LOAD) through genome-wide association studies (GWASs). ABCA7 is a member of the ATP-binding cassette (ABC) transporter gene superfamily, which codes for 49 ABC proteins, divided into 7 subfamilies (coded A–G). As a(More)
S-Nitrosylation, a redox-mediated posttranslational modification, is a result of the covalent binding nitric oxide (NO)-related species to cysteine residues of target proteins with the formation of nitrosothiols (SNOs). Normally, protein S-nitrosylation could be a cellular signaling mechanism, as is often a reversible and selective process, akin to protein(More)
