The plasmonic coupling between gold caps and holes in thin films was investigated experimentally and through finite-difference time-domain (FDTD) calculations. Sparse colloidal lithography combined with a novel thermal treatment was used to control the vertical spacing between caps and hole arrays and compared to separated arrays of holes or caps. Optical spectroscopy and FDTD simulations revea...

OBJECTIVE To determine an association between transmission of hepatitis B virus and secretor and non-secretor status of salivary blood group antigens. STUDY DESIGN Cross-sectional, analytical study. PLACE AND DURATION OF STUDY The Department of Physiology and Division of Hepatology, College of Medicine, King Khalid University Hospital, King Saud University, Riyadh, Kingdom of Saudi Arabia, ...

occult hbv infection of hemodialysis (hd) patients is informative in terms of virus transmission. it may be of clinical importance in hd patients. the aim of this study was to investigate the prevalence of anti-hbc in the hd patients. number of 126 patients undergoing hemodialysis were included in this study from main hemodialysis units in yazd. hepatitis b surface antigens (hbsag), hepatitis b...

The sensitivity of passive bacterial agglutination (PBA), i.e., the agglutination of Staphylococcus aureus coated with antibodies to hepatitis B surface antigen by hepatitis B surface antigen, was assessed by testing reference panel no. 3A sera (Bureau of Biologics, U.S. Food and Drug Administration). Of the 23 samples containing hepatitis B surface antigen, 18 were positive by PBA. Sera from 1...

BACKGROUND There have been conflicting data in literature about the value of Phyllanthus amarus in treating hepatitis B virus-related disorders. AIM To evaluate the role of Phyllanthus amarus in eradication of the virus in hepatitis B carriers. METHODS Phyllanthus amarus was administered to 30 asymptomatic carriers of hepatitis B surface antigen (HBsAg) in a dosage of 250 to 500 mg thrice d...

OBJECTIVE To evaluate the efficacy of hepatitis B virus (HBV) vaccine in susceptible spouses at the time of marriage. METHODS From April 2003 to December 2005, 60 cases of susceptible wives of infected husbands and 32 cases of susceptible husbands of the infected wives in Babol north of Iran, received recombinant hepatitis B (HB) vaccine at the time of marriage followed with the second and th...

The formation of self-organized micro- and nano-structured surfaces on nickel via both above surface growth (ASG) and below surface growth (BSG) mechanisms using femtosecond laser pulse illumination is reported. Detailed stepped growth experiments demonstrate that conical mound-shaped surface structure development is characterized by a balance of growth mechanisms including scattering from surf...

background the transmission of hepatitis b virus (hbv) is parenteral, sexual and prenatal. prevention of vertical transmission of hbv is extremely important, because hbv infection in early life usually results in a chronic carrier state. there has been so much debate about hepatitis b surface antigen (hbsag) screening in pregnant women. objectives the aim of this study was to determine the prev...
