In the near future the capability of the human beings to communicate sensations is going to be enhanced by incorporating the five sensory features in the messages and allowing more expressive and holistic sensory information exchange through communication techniques. The human bond communication (HBC) is currently a vision, but it is expected to become true. The objective of this paper is to gi...

Different types of vaccines have been developed to elicit active immunization to treat various diseases, while suffer from limitation of efficacy. Herein, a novel immunostimulatory nanocomposite (CpG-Au@HBc VLP) was rationally designed by self-assembling engineered virus-like particles encapsulating CpG-gold nanoparticle conjugates through electrostatic interactions. The monodispersed and unifo...

This study aims to evaluate the efficacy of HBV vaccination as an alternative preventive measure against de novo HBV infection in pediatric living donor liver transplantation (LDLT). Sixty recipients were enrolled in this study. Thirty received grafts from anti-HBc(+) donors, and another 30 received grafts from anti-HBc(-) donors. HBV vaccine was given pretransplant to every candidate. Posttran...

AIM To evaluate the impact of hepatitis B core antibody (anti-HBc) seropositivity in sustained virological response (SVR) rates in treatment-naïve, chronic hepatitis C (CHC) patients with high pretreatment viral load (>800000 IU/mL). METHODS 185 consecutive CHC patients (14.4% cirrhotics, 70.2% prior intravenous drug users) treated with pegylated interferon-a2b plus ribavirin, for 24 or 48 we...

A protoplast fusion method was developed to stably transfect human cells with pSV2-derived plasmids at frequencies greater than 10(-3). This procedure made it possible to test the biological effect of a hepatitis B virus (HBV) gene independent of the viral structures required for infection. A pSV2gpt+ plasmid constructed to carry a subgenomic fragment of HBV that contained the core antigen gene...

Reducing agents dramatically alter the specificity of competitive assays for antibody to hepatitis B core antigen (anti-HBc). A specificity improvement was demonstrated with a new assay which utilizes microparticle membrane capture and chemiluminescence detection as well as a current radioimmunoassay procedure (Corab: Abbott Laboratories, Abbott Park, Ill.). The effect was most noticeable with ...

The gene frequencies of haemoglobin A (HbA), HbS and HbC were studied in Burkina-Faso (BF) and in a neighbouring region of Niger, Ayorou. The frequency of HbS was higher in the Sahel region, (northern part of BF and Ayorou) than in the Savanna region. The reverse was true for the HbC gene. The major findings of this study are: (a) confirmation of a peak of HbC gene frequency in the central regi...

BACKGROUND & OBJECTIVES Expansions of blood donor screening and improved laboratory detection of viral markers have remarkably reduced the risk for infection with transfusion-transmitted viruses. This study was aimed to evaluate the presence of anti-HBc and to determine the presence or absence of HBV DNA in the serum samples from HBsAg negative, anti-HBc positive blood donors in a tertiary care...

BACKGROUND The role of MCP1-2518 A/G in hepatitis B virus (HBV) infection is controversial. Our aim was to evaluate the frequency distribution of MCP1-2518 A/G (rs1024611) polymorphic variants in hemodialysis (HD) patients without or with type 2 diabetes in relation to serological markers of HBV infection. MATERIAL AND METHODS HD patients (n=170, 48 with diagnosis of type 2 diabetes), who tes...

Furnas dos Dionísios is an Afro-Brazilian black community whose descendants were mainly fugitive slaves that established themselves in the State of Mato Grosso do Sul (MS), Brazil. The population is comprised mainly of low socioeconomic individuals who are engaged in agricultural activities. The objective of this study was to investigate the prevalence of hepatitis B (HB) and its correlation wi...
