We investigated the associations between single nucleotide polymorphisms (SNPs) in the testis-specific Y-encoded-like protein 6 (TSPYL6) gene and breast cancer (BC) susceptibility in the Han Chinese population. A total of 183 BC patients and 195 healthy women were included in the study. Six SNPs in TSPYL6 were genotyped and the association with BC risk analyzed. Odds ratios (ORs) and 95% confid...
Increasing wildfire activity in the Alaskan Arctic may result in new sources of black carbon (BC) to arctic watersheds. Black carbon, primarily comprised of condensed aromatics, is one of the most chemically recalcitrant fractions of organic carbon. However, lateral transfer of particulate and dissolved BC from soils to sunlit surface waters is increasingly suggested to result in the photochemi...
this article presents the application of two algorithms: heuristic big bang-big crunch (hbb-bc) and a heuristic particle swarm ant colony optimization (hpsaco) to discrete optimization of reinforced concrete planar frames subject to combinations of gravity and lateral loads based on aci 318-08 code. the objective function is the total cost of the frame which includes the cost of concrete, formw...
granymeh is a functional cytotoxic serine protease of nk cell granules,which expands the cell death-inducing repertoire of innate immune system.the purpose of this study was to determine granymeh(gzmh)level in breast cancer(bc) and healty women.this study was performed on 30 patients with bc and 30 healty woman.gzmh and estrogen levels were measured in cancer patients and healty women subseque...
Measurements of black carbon (BC) concentration have long been uncertain. Neither a BC standard or a technique that provides a reliable measurement of BC exist, which precludes the evaluation and optimization of BC measurement methods. In this manuscript, we describe the generation of BC particles (mass absorption efficiency 8.5m g 1 and single scattering albedo 0.2 at 530 nm) using an inverted...
The blowfly Calliphora has a preferred flight attitude from which it may transiently deviate either actively by voluntary aerobatics or, passively, by air turbulence. In order to regain its normal flight attitude the fly performs simultaneously a corrective flight manoeuvre and a compensatory head turn. This is made possible because Calliphora can turn its head about all 3 principal axes of its...
Optically transparent membranes from bacterial cellulose (BC)/polycaprolactone (PCL) have been prepared by impregnation of PCL acetone solution into dried BC membranes. UV-Vis measurements showed an increase on transparency in BC/PCL membrane when compared with pristine BC. The good transparency of the BC/PCL can be related to the presence of BC nanofibers associated with deposit of PCL nano-si...
