The association between XRCC6 C1310G and cancer risk was assessed by the pooled odds ratio (OR) with 95 % confidence intervals (95 % CI) calculated by meta-analysis. A total of 15 eligible studies (4,642 cancer cases and 6,059 controls) were identified. Overall, there was obvious evidence for an association between XRCC6 C1310G polymorphism and increased risk of cancer under two genetic comparisons (GG vs. CC: fixed-effect OR 1.35, 95 % CI 1.10-1.66, I (2) = 17.0 %; GG vs. CG/CC: fixed-effect

OR 1.25, 95 % CI 1.02-1.53, I (2) = 0.0 %). Subgroup analysis indicated that the association VX-770 mouse was significant in Asians (G vs. C: random-effect OR 1.13, 95 % CI 1.01-1.26, I (2) = 51.3 %; GG vs. CC: fixed-effect OR 1.43, 95 % CI 1.14-1.81, I (2) = 0.0 %; GG vs. CG/CC: fixed-effect OR 1.37, 95 % CI 1.09-1.72, PP2 in vitro I (2) = 0.0 %), but not in Europeans. Data from the current meta-analysis support the existence of an association between XRCC6

C1310G polymorphism and cancer risk in Asians. Studies with larger sample size are needed to further evaluate the influence of XRCC6 C1310G polymorphism on susceptibility of various cancers.”
“Hedgerows provide key habitat and refuges for wildlife in otherwise intensively-managed landscapes, and may play a role in connecting increasingly fragmented habitats. However, the processes governing changes to the floral biodiversity of hedges are poorly understood. We analysed a unique, long-term data set of plant species richness over a 70 year period at 357 hedgerow sites

in southern England to quantify changes in alpha, beta and gamma diversity, and identify the role of hedge management and other possible drivers of change. Alpha diversity increased in hedgerows, while a reduction in beta diversity was indicated by taxonomic homogenisation, whereby previously distinct communities of species become more similar to one another over time. Changes in the regional species pool (gamma diversity) differed with plant life-history; it increased for woody species but decreased among herbaceous hedge species. Hedgerow communities shifted towards species associated with higher soil fertility, a more competitive ecological strategy and, in unmanaged hedgerows, greater shade tolerance. Probable drivers for these changes include the move from traditional Crenigacestat forms of management such as coppicing and hedge-laying towards either no management or frequent cutting with a mechanical flail, and eutrophication. The extent of changes in plant diversity over time was determined by both historical and recent hedgerow management, but these management effects varied with plant life-history attributes. However, changes in hedge quality and floral diversity were not linked directly to a 60% increase in the proportion of land use categories classified as ‘intensive’ adjacent to the sites over the 70 years.
