background recommendations to immunize healthcare workers (hcws) against hepatitis b are well known. however, a proportion of individuals do not respond to the primary standard three-dose hb vaccination schedule. conclusions both the single- and double-dose hb vaccines were adequately immunogenic, and the double-dose hb vaccine was not significantly more immunogenic than the single-dose vaccine...

BACKGROUND We analyzed serologic data that were obtained from the Korea Association of Health from 1995 to 1999 to estimate the reliable prevalence of HBV in South Korea. METHODS 603,375, 639,465, 621,476, 612,705 and 650,398 serum samples were annually tested for HBsAg. Of HBsAg positive persons whose serum samples were available, HBeAg positivity was checked. RESULTS HBsAg positivities am...

This special issue on surface chemistry is introduced with a brief history of the field, a summary of the importance of surface chemistry in technological applications, a brief overview of some of the most important recent developments in this field, and a look forward to some of its most exciting future directions. This collection of invited articles is intended to provide a snapshot of curren...

Introduction In general, the twentieth century marked the first major incursion of chemists into the world of tribology. Driven partly by the need for improved lubricants for new machines developed in the first few decades of the century, and partly by new analytical capabilities, lubricant chemists and tribochemists were to become full partners in the science of tribology. In this review we co...

Background: Hepatitis B virus infection is a worldwide health problem. Vertical transmission is a route of Hepatitis B virus infection that is regarded as a considerable factor in Hepatitis B virus prevention program all over the world. Objective: This study was conducted to screen the hepatitis B surface antigen, hepatitis B surface antibody and hepatitis B e antigen in pregnant women. Methods...

INTRODUCTION Few studies have focused on hepatitis B virus (HBV) infection among childbearing-age women. This study explored hepatitis B surface antigen (HBsAg) seroprevalence and hepatitis B e antigen (HBeAg) seroprevalence and their associated factors among childbearing-age women. METHODOLOGY A cross-sectional, population-based study was conducted between June 2013 and October 2013 in Miany...

Structured films with periodic arrays of nanoholes covered by half-cone shells are fabricated via a simple and efficient colloidal lithography method. The designed films show strong polarization dependence in optical transmission. By decreasing the height of half-cone shells the peak shifts and this shift varies strongly for different orthogonal polarizations. Furthermore, the three-dimensional...

Surface plasmon resonance imaging and surface plasmon induced fluorescent are sensitive tools for surface analysis. However, existing instruments in this area have provided limited capability for concurrent detection, and may be large and expensive. We demonstrate a highly cost-effective system capable of concurrent surface plasmon resonance microscopy (SPRM) and surface plasmon resonance-enhan...

For binary mixtures with fixed concentrations of the species, various relationships between the surface tensions and the concentrations are briefly reviewed.
