The hepatitis B virus (HBV), family Hepadnaviridae, is one of most relevant human pathogens. HBV origins are enigmatic, and no zoonotic reservoirs are known. Here, we screened 3,080 specimens from 54 bat species representing 11 bat families for hepadnaviral DNA. Ten specimens (0.3%) from Panama and Gabon yielded unique hepadnaviruses in coancestral relation to HBV. Full genome sequencing allowe...

DNA vaccines could induce protective immune responses in several animal models. Many strategies have been employed to improve the effect of nucleic acid vaccines. LIGHT is a member of the TNF superfamily and functions as a co-stimulatory molecule for T cell proliferation. In the study, the immunogenicity in the induction of humoral and cellular immune responses by HBV DNA vaccine and the adjuva...

BACKGROUND Nucleic acid test (NAT) hepatitis B virus (HBV) screening for all blood donations with a sensitivity limit of 25 IU/mL in the individual donation is mandatory in Switzerland since 2009. The aims of the two studies were to define the percentage of antibody to hepatitis B core antigen (anti-HBc) or anti-HBc and antibody to hepatitis B surface antigen (anti-HBs)-positive donors bearing ...

The primary hepatocytes cultured from adult BALB/c mice were readily transfected by plasmid DNA and could be immortalized at a frequency of approximately 0.1 to 0.6 x 10(-7) cells/micrograms of the transfected DNA. There was no detectable plasmid DNA at the tenth cell passages. A total of five mouse hepatocyte cell lines were established. Most of them were tumorigenic. Three of the established ...

Hepatocellular carcinoma (HCC), the third leading cause of cancer deaths worldwide, is most commonly caused by chronic hepatitis B virus (HBV) infection. However, whether HBV plays any direct role in carcinogenesis, other than indirectly causing chronic liver injury by inciting the host immune response, remains unclear. We have established two independent transgenic mouse lines expressing the c...

We have evaluated the new Digene Hybrid Capture II HBV DNA Test (HCII HBV), which is a 96-well microtiter plate-based signal amplification assay. This test uses hybrid capture technology that specifically detects RNA-DNA hybrids. HCII HBV is able to quantify hepatitis B virus (HBV) DNA at between 1.4 x 10(5) and 1.7 x 10(9) HBV copies per ml in a standard format. By using a modified sample prep...

UNLABELLED The determinants of the maintenance of chronic hepadnaviral infection are yet to be fully understood. A long-standing unresolved argument in the hepatitis B virus (HBV) research field suggests that during chronic hepadnaviral infection, cell-to-cell spread of hepadnavirus is at least very inefficient (if it occurs at all), virus superinfection is an unlikely event, and chronic hepadn...

The creation and manipulation of conceptual shapes need different modeling techniques from what are available in present CAD systems. Conceptual modeling techniques are supposed to provide more flexible interaction and mimic working with true materials. Therefore, this paper proposes a new computer internal modeling technique that supports the natural ways of exteriorizing shape concepts as wel...

Today, the fast changes and developments of environmental factors have augmented the complexity and ambiguity of the situations so the old paradigms would not be suitable to tackle the problems. This paper tries to use a new approach that encompasses a set of concepts to face the new complex situations. It is a combination of behavioral and managerial concepts that has not yet been published in...

BACKGROUND Many studies suggest that in chronic hepatitis B virus (HBV) infection regulate T (Treg) cells and interlukin-17-producing T help cells (Th17) are mutually antagonistic in the immune response. This study is aimed to reveal the cell differentiation environment and the significance of Treg and Th17 balance in the development of acute and chronic HBV infection. METHODS Ten patients wi...
