epidemiology studies have demonstrated inconsistent associations between type 2 diabetes mellitus and the risk of malignant melanoma. to this end, the aim was to perform a meta-analysis of cohort studies.medline, pubmed, embase and the cochrane library were searched up to february 2014. cohort studies addressing the relative risk of type 2 diabetes mellitus on malignant melanoma were included i...

the aim of this research was to perform a systematic review of the efficacy of non-hormonal herbal drugs in the treatment of vaginal atrophy in postmenopausal women. three electronic databases were systematically searched from their inception to may2015: pubmed, cochrane library (cochrane central register of controlled trials) and scopus. in this meta-analysis, vaginal maturation value was cons...

This paper uses the concept of Meta-frontier to investigate the relationship between Meta Technology Ratios (MTR) and different varieties in datepalms including; Mazafati, Rabi and Zardan that are produced widely in Sistan and Baluchestan province of Iran. We used a stratified sampling of 300 date farmers of this province in 2010, 2011 and 2012 and estimated a stochastic production frontier usi...

Recently, we presented ContextMap (Bonfert et al., 2012), a novel approach to mapping RNA-seq reads based on the concept of a so-called read context. A context is defined as a set of reads all originating from the same stretch of the genome, indicating that they all correspond to transcripts of the same gene. The original implementation we presented was focused on refining initial mappings prov...

We describe a hybrid meta-heuristic algorithm for combinatorial optimization problems with a specific reference to the travelling salesman problem (TSP). The method is a combination of a genetic algorithm (GA) and greedy randomized adaptive search procedure (GRASP). A new adaptive fuzzy a greedy search operator is developed for this hybrid method. Computational experiments using a wide range of...

background :cytotoxic t lymphocyte-associated antigen-4 (ctla-4) is an important negative regulator of t-cell responses. the -1722tc polymorphism of the ctla-4 gene may be associated with systemic lupus erythematosus (sle) risk, but related results from previous studies have been inconsistent. we carried out a meta-analysis to assess this association more precisely.   methods : a systematic sea...
