Approximately 170 million people in the world are infected with Hepatitis C virus (HCV). There are no published population based studies about the prevalence of HCV genotypes and the associations of genotype and Infection frequency with gender and age in WuHan. We aimed to investigate the distribution of HCV prevalence and genotypes among different gender and age patients with chronic HCV infec...
We present two catalogues of galaxies in the direction of the rich cluster ABCG 496. The first one includes 3,879 galaxies located in a region of roughly ± 1.3◦ from the cluster centre. It has been obtained from a list of more than 35,000 galaxy candidates detected by scanning part of a Schmidt photographic plate taken in the bJ band. Positions are very accurate in this catalogue but magnitudes...
We present the results of a spatially-resolved spectroscopic analysis of the galaxy cluster Abell 496 with the S3 chip on-board the Chandra satellite. We confirm the presence of a central positive temperature gradient consistent with a cooling flow, but with a minimum gas temperature of ∼0.5–0.9 keV. The cluster also exhibits sharp edges in gas density and temperature which are consistent with ...
The effects of chronic low-dose radiation on human health have not been well established. Recent studies have revealed that neural progenitor cells are present not only in the fetal brain but also in the adult brain. Since immature cells are generally more radiosensitive, here we investigated the effects of chronic low-dose radiation on cultured human neural progenitor cells (hNPCs) derived fro...
The aim of the study was to compare the manual and rotary endodontic instruments focusing on risk of perforation when the whole root canal length is instrumented as well as the time required for preparation in primary teeth Fifty four teeth were divided randomly into three groups.Group I: The root canals were prepared manually with K-files. Group II : ProTaper instruments were used in a crown-d...
PURPOSE: Cystic echinococcosis (CE) is a serious medical and social problem for the public healthcare in Bulgaria. The average incidence of the disease remains steady during the past 5 years-4.45/100000, while the average incidence rate for Kardzhali region was 8.02/100000. These data however do not reveal the morbidity of cystic echinoccoccosis in various settlements in the region. The aim of ...
