background: available drugs are not able to eradicate intracellular viral dna in patients with hepatitis b virus (hbv) infections. hbsag vaccine could induce immunity and subsequently eradicate hepatitis b virus in proportions of these patients. our aim was to evaluate the efficacy of hbsag as a mode of therapy in inactive carriers. materials and methods: forty two consecutive patients of inact...

background and objectives: neisseria meningitidis is transmitted from person-to-person. thus, close contact with a healthy carrier can facilitate the spread of the bacteria and lead to life-threatening meningococcal disease. the aim of this study was to identify oropharyngeal carriers of n. meningitidis in volunteers preparing for military service before vaccination. materials and methods: in a...

background: it is estimated that about 370 million people are chronic carriers of hbv worldwide. apparently 3% of iranian populations are chronic carriers of this virus. we aimed to evaluate the viral dna in biological fluids of chronic hepatitis patients compared to a control group. methods: the current case-control study was designed to evaluate the viral dna in biological fluids of 70 chroni...

To take into account the presence of multiple light-induced defect states in hydrogenated amorphous silicon (a-Si:H) the evolution of the entire spectra of photoconductive subgap absorption, a(hn), has been analyzed. Using this approach two distinctly different light-induced defect states centered around 1.0 and 1.2 eV from the conduction band edge are clearly identified. Results are presented ...
