The purpose of this research was to compare the causes death in 5 villages situated Simav Plain, Turkey, during 2005-2010 where different arsenic levels were detected drinking water supplies. Since groundwater Plain had concentrations that ranged between 7.1 and 833.9 ppb, a two-phase formulated. In first phase, public health surveys conducted with 1,003 villagers determine distribution diseases. second verbal autopsy official records used investigate death. total, 402 cases found study area...
The corrosion of dental alloys has biological, functional, and aesthetic consequences. Various studies have shown that protein solutions can inhibit the alloys. This study is planned to determine relationship organic constituents saliva are IgA, mucine, urea, lysozyme which encountered in highest amounts materials titanium (Ti), Co-Cr-Mo Ni-Cr-Mo alloys, amalgam, most often used metallic components dentistry. In particular, interactions between commonest salivary proteins, urea lysozyme, Ti,...
The objective of this study was to evaluate the topographical effects titanium surfaces created by sandblasting and oxalic acid etching on adhesion human fetal osteoblast cells (CRL-11372) in vitro after 24 hours. Osteoblast were cultured polished (Ti) discs (Control Group), alumina (Al2O2) particle blasted etched (20 min) Ti discs, for 20 min, 60 min. topographies roughness modified assessed. Cell count, cell viability morphologic differences between adhering evaluated. results showed that...
RAD51 is the key component of homologous recombination pathway in eukaryotic cells and performs its task by forming filaments on DNA. In this study we investigate physical properties formed DNA using nanofluidic channels fluorescence microscopy. Contrary to bacterial ortholog RecA, forms inhomogeneous long vitro, consisting several protein patches. We demonstrate that a permanent "kink" filament where two patches meet if stretch naked between short. The kinks are readily seen present...
This study was conducted to characterize titanium (Ti) metal surfaces modified by polishing, coating with nitride, oxide, sandblasting alumina (Al 2 O 3 ) particles and plasma spray (TPS); evaluate the effect of surface roughness crystalline structure on adhesion human fetal osteoblast cells (CRL-11372) in vitro after 24 hours. Surface topography were examined scanning electron microscopy (SEM) a noncontacting optical profilometer, respectively. The structures coatings characterized X-ray...

In this study, micro alloy steel (St 35) surfaces, which were coated with dierent hard electrode materials via Electro Spark Deposition (ESD) method, have been characterized.The chosen among alloys such as; TiCN(Ni), CrC-NiCr, WC(Co) and TiWC(Co).During the ESD experiments, following pulse parameters in a group used: current amplitude, duration, electrical charge of 100200 A, 100 µs, 1000 mC respectively.The surface roughness, thickness coatings, cross sectional microstructure analysis,...
In the present study, rst Ti6Al4V alloy was deposited on steel (AISI 1060) surfaces by using ESD method.The optimum electrical parameters for coating process were investigated to obtain high quality coatings.Then, in order gain bio-compatibility and second layer, which coated with hydroxyapatite (HAp), MAO technique applied coating.Resulting duplex layers characterized X-ray diraction (XRD) scanning electron microscopy (SEM) energy dispersive spectroscopy (EDX) analysis together surface...
