Compliance with and responses to the hepatitis B vaccine were evaluated in remaining quilombo communities in Central Brazil. A total of 708 individuals who were susceptible to hepatitis B virus infection were invited to participate in the hepatitis B vaccination program in eight communities. Although 567 (80%) individuals received the first dose, only 198 (28%) complied with the full vaccinatio...
BACKGROUND Since its development in the early 1980s, Hepatitis B virus (HBV) vaccine has been proven to be highly protective. However, its immunogenicity may be ineffective among HIV-infected children. In Morocco, HBV vaccine was introduced in 1999, and since then all infants, including vertically HIV-infected infants, have been following the vaccination schedule, implemented by the Moroccan mi...
Hepatitis B virus (HBV) has a low endemicity in Rio de Janeiro, Brazil. Sexual transmission must play an important role in this virus, but the prevalence and risk factors have never been properly investigated. The aim of this paper is to determine the prevalence and risk factors for HBV infection in patients attending a Sexually Transmitted Diseases Clinic of the Universidade Federal Fluminense...
BACKGROUND There is no standard management of reactivation of hepatitis B virus (HBV) infection in HBV-resolved patients without hepatitis B surface antigen (HBsAg), but with antibodies against hepatitis B core antigen and/or antibodies against HBsAg (anti-HBs). METHODS We conducted a prospective observational study to evaluate the occurrence of HBV reactivation by serial monthly monitoring o...
In this solid-phase two-site enzyme immunoassay for hepatitis B surface antigen (HBsAg), three monoclonal anti-HBs are used: 5D3 (IgM) is immobilized on plastic beads; 5C3 (IgG2a) and 5C 11 (IgG1), labeled with biotin, are used as the first conjugate. Horseradish peroxidase covalently linked to avidin is the second conjugate. First, serum or plasma is incubated with the antibody-coated bead and...
میکروارگانیسم ها برای سازمان دهی و بسته بندی dnaی خود از تعدادی پروتئین بازی کوچک استفاده می کنند. این پروتئین ها بر روی بیان ژن، رفتار رشد و قابلیت زیست میکروارگانیسم ها، تاثیر عمیقی دارند. این پروتئین هاًٌٌٍٍُُِْ، پروتئین های شبه هیستونی نامیده می شوند.یکی از پروتئین های شبه هیستونی که به خوبی مطالعه شده است، پروتئین hu از باکتری e.coli می باشد. پروتئین hbsu از bacillus subtilis یکی از اعضای خانو...
one of the most serious kinds of hepatitis is hepatitis b. this condition is more common than aids, and is 100 time more contagious. in iran the most common cause of acute and chronic hepatitis, liver cirrhosis, and also hepatocellar carcinoma in adults, is hepatitis b. more than two billion people are infected and more than 350 million of individuals are carriers of this virus in the entire wo...
Recently, hybrid band communications have received much attention to fulfil the exponentially growing user demands in next-generation communication networks. Still, determining best communicate over is a challenging issue, especially dynamic channel conditions multi-band wireless systems. In this paper, we manipulate practical online-learning-based solution for band/channel selection radio freq...
To study the inhibitory effects of plasmid-derived small interfering RNA (siRNA) and synthetic siRNA on the expression of the hepatitis B virus surface (HBs) gene, three plasmid-derived siRNAs and one synthetic siRNA that complement the coding region of the HBs gene were prepared. The HBs expression plasmid pHBs-EGFP was also constructed. HeLa cells were co-transfected with pHBs-EGFP and the ab...
