The genus Burkholderia (β-Proteobacteria) currently comprises more than 60 species, including parasites, symbionts and free-living organisms. Several new species of Burkholderia have recently been described showing a great diversity of phenotypes. We examined the diversity of Burkholderia spp in environmental samples collected from Caatinga and Atlantic ... more

16S rDNA; Actinomycetes; Antarctic; Barrientos Island; PCR-DGGE

The diversity of specific bacteria taxa, such as the actinomycetes, has not been reported from the Antarctic island of Barrientos. The diversity of actinomycetes was estimated with two different strategies that use PCR-denaturing gradient gel electrophoresis. First, a PCR was applied, using a group-specific primer that allows selective amplification of actinomycete sequences. Second, a ... more

We investigated the biodegradability of oil in mangrove sediment from Camamu Bay and measured its effect on the bacterial community. Microcosms of mangrove sediment were contaminated with 0.1, 0.5, 1, 2, and 5% (w/v) oil, and the microbial activity was compared to that in uncontaminated sediment. The evolution of CO2 and gas chromatography showed the mineralization of oil ... more

16S rDNA; Caragana microphylla; Diversity; Endophytic bacteria

The diversity of endophytic bacteria in the sand-fixation plant Caragana microphylla was investigated by amplified rDNA restriction analysis and by sequence and phylogenetic comparisons of the 16S rRNA genes. A total of 24, 19, and 17 operational taxonomic units were identified from 16S rDNA libraries of the plant roots, stems and leaves, respectively. Homology analysis revealed a ... more

Angiopolybia pallens is a swarm-founding wasp that occurs in Atlantic and Amazonian rainforests, which have been isolated from each other by a large arid corridor in central Brazil since the Tertiary. In this study, we used data from polymerase chain reaction-restriction fragment length polymorphism of 16S rDNA to infer some aspects of the genetic diversity and evolutionary ... more

Coronary artery disease; IL-10-1082A/G; Polymorphism

We conducted a case-control study to investigate the association between IL-10-G1082A (rs1800896) polymorphism and the development of coronary artery disease (CAD) in the Chinese population. We recruited 295 CAD patients and 355 healthy controls from the Fifth Affiliated Hospital of Zhengzhou University between April 2012 and December 2014. Subjects were genotyped for IL-10 ... more

We conducted a prospective study to investigate whether ERCC1 rs11615 and rs3212986 and ERCC2 rs13181 and rs1799793 gene polymorphisms could serve as potential biomarkers for the prognosis of gastric cancer. Between January 2010 and December 2012, 246 patients with pathologically proven gastric cancer who were receiving platinum-based chemotherapy were recruited from the ... more

Bladder cancer; CYP1A2; Polymorphism; Risk

To date, no study has investigated the association between CYP1A2-163C/A polymorphism and bladder cancer risk in a Chinese population. Here, we extracted genomic DNA from peripheral white blood cells, and differentiated CYP1A2 alleles by polymerase chain reaction-based restriction fragment length polymorphism methods. Differences in genotype frequencies between the cases ... more

Meta-analysis; Monoamine oxidase B; Parkinson’s disease; Polymorphism

Although various individual studies have evaluated the correlation between monoamine oxidase B (MAOB), polymorphism, and Parkinson’s disease (PD), the results remain inconclusive. Therefore, we performed a meta-analysis in the Chinese population to provide comprehensive data on the association between the MAOB polymorphism and PD. Eligible studies were identified via databases such as ... more
