Worldwide, some 240 million people have chronic hepatitis B virus (HBV), with the highest rates of infection in Africa and Asia. Our understanding of the natural history of HBV infection and the potential for therapy of the resultant disease is continuously improving. New data have become available since the previous APASL guidelines for management of HBV(More)
Air pollution in urban cites is caused not only by local emission sources but also significantly by regional atmospheric pollutant transport from surrounding areas. This study is to identify regional atmospheric PM10 transport pathways through an integrated modeling and synoptic pressure pattern analysis approach with a case study in Beijing, northern(More)
The thermal dynamic influence of microstructure and physical phase leading to the variation on the short-circuit density (J<sub>sc</sub>) for the large size of CIGS solar cell has been investigated by the subsequent rapid thermal annealing (RTA) and optical and electrical analyses, respectively. The annealing temperature of 300&#x00B0;C is an optimized(More)
Electroluminescence devices based on nanocrystalline Si/SiO<sub>2</sub> multilayers were fabricated and the luminescence can be observed both from vertical and lateral direction. Moreover, P-doped nanocrystalline Si/SiO<sub>2</sub> multilayers were prepared and the improved electro-luminescence characteristics were achieved.
Two hundred and twenty two asymptomatic carriers of hepatitis B surface antigen (HBsAg) with age between 4 months and 68 years, 172 healthy persons with antibody to HBsAg (anti-HBs) and 85 healthy persons seronegative for both HBsAg and anti-HBs were studied by double immunodiffusion for the evaluation of the meaning of hepatitis B e antigen (HBeAg) and its(More)
To evaluate the sensitivity of a polymerase chain reaction (PCR) assay using nested primers in detectingHelicobacter pylori, gastric tissue biopsy specimens were collected on endoscopy from 17 patients with a duodenal ulcer. DNA was extracted by phenol/chloroform treatment or boiling in water, and then subjected to a nested PCR using two primer pairs from(More)
