The aim of our meta-analysis was to assess the association between BDNF Val66Met polymorphism and treatment response in patients with MDD. 8 studies that included data from 1115 subjects were identified. We tested two phenotypes: response rate and remission rate. OR was used as a measure of the effect of the association in a fixed/random effect model.(More)
The aim of this study was to summarize results on the association of tumor necrosis factor-α (TNF-α) promoter -308A/G polymorphism with systemic lupus erythematosus (SLE) susceptibility in Asian populations by using the meta-analysis. We searched all the publications about the association between TNF-α promoter -308A/G polymorphism and SLE in Asian(More)
We study the existence and multiplicity of positive periodic solutions for second-order nonlinear damped differential equations by combing the analysis of positiveness of the Green function for a linear damped equation. Our nonlinearity may be singular in its dependent variable. The proof of the main result relies on the Guo-Krasnosel'skii fixed point(More)
