BACKGROUND The -1082G/A polymorphism in IL-10 gene has been extensively investigated for association to Alzheimer's disease (AD), however, results of different studies have been inconsistent. The objective of this study is to assess the relationship of IL-10 -1082G/A polymorphism and AD risk by using meta-analysis. METHODS All eligible case-control(More)
BACKGROUND The insertion/deletion (I/D) polymorphism in the Angiotensin-converting enzyme (ACE) gene has been implicated in susceptibility to cancer, but a large number of studies have reported inconclusive results. The aim of this study is to assess the association between the I/D polymorphism in the ACE gene and cancer risk by meta-analysis. METHODS A(More)
BACKGROUND The -2518A/G polymorphism in the monocyte chemoattractant protein-1 (MCP-1) gene has been implicated in the susceptibility to tuberculosis (TB), but the results are not conclusive. The aim of this study is to investigate the association between the -2518A/G polymorphism in the MCP-1 gene and the risk of tuberculosis by meta-analysis. METHODS We(More)
BACKGROUND Published data regarding the associations between genetic variants and asthma risk in Chinese population were inconclusive. The aim of this study was to investigate asthma susceptible genes in Chinese population. METHODS The authors conducted 18 meta-analyzes for 18 polymorphisms in 13 genes from eighty-two publications. RESULTS Seven(More)
The Val158Met polymorphism in the COMT gene may affect the DNA repair pathways and be associated with the risk of cancer in Chinese population. However, the results of previous studies are inconsistent. The objective of this study was to investigate the association between the Val158Met polymorphism in the COMT gene and the risk of cancer for Chinese(More)
We consider the impact of job rotation in a directed search model in which …rm sizes are endogenously determined and match quality is initially unknown. A large …rm bene…ts from the opportunity to rotate workers so as to partially overcome the loss of mismatch. As a result, in the unique symmetric equilibrium, large …rms have higher labor productivity and(More)
