In order to elucidate the structure and morphology of hepatitis G virus (HGV), a recently isolated flavivirus, we generated a panel of eight monoclonal antibodies (MAbs) against the putative second envelope protein (E2) following DNA immunization. The MAbs were shown to be specific for four different epitopes on recombinant E2. MAb Mc6 was the only antibody able to detect the linear epitope LTG...
BACKGROUND Hepatitis viruses are one of the most important concerns in the patients on hemodialysis who are at high risk for blood-borne infections. GB virus C (GBV-C)/hepatitis G virus (HGV) is positive-stranded RNA virus with global distribution, which codes structural and nonstructural proteins (such as NS3). OBJECTIVES Review on literature about Iranian HGV isolates showed that there was ...
سابقه و هدف: عفونت با ویروسهای عامل هپاتیت در بیماران مبتلا به ویروس نقص ایمنی انسان ( hiv ) به واسطهی راههای انتقال مشابه به وفور وجود دارد. عفونت با این ویروسها منجر به کاهش بقای بیماران مبتلا به ویروس نقص ایمنی انسان میگردد. اما برخلاف انتظار برخی مطالعات حکایت از این دارند که عفونت همزمان با hgv سبب کاهش پیشرفت عفونت hiv به طرف ایدز و در پایان مرگ میشود. هدف از این تحقیق بررسی میزان ...
Comparative sequence analysis of different isolates of hepatitis G virus (HGV) has demonstrated significant intersubject genetic heterogeneity, but few data on intrasubject genetic evolution have been reported. To further investigate the genetic diversification of the HGV genome, 36 plasma samples from eleven patients chronically infected with HGV serially obtained 2-4 years apart were analysed...
To evaluate the risk of transmitting blood-borne GB virus C/hepatitis G virus (GBV-C/HGV) and to define the natural course of infection, we performed a prospective study in a cohort of multitransfused beta-thalassemics during a 6-year follow-up period. We analyzed serum samples of 150 patients collected at 3-year intervals from 1990 to 1996. GBV-C/HGV RNA was determined by reverse transcriptase...
Penetration trajectory optimization for the hypersonic gliding vehicle encountering two interceptors
The penetration trajectory optimization problem for the hypersonic gliding vehicle (HGV) encountering two interceptors is investigated. HGV considering terminal target area formulated as a nonconvex optimal control problem. transformed into second-order cone programming (SOCP) problem, which can be solved by state-of-the-art interior-point methods. In addition, strategy that only requires initi...
چکید ه سابقه و هدف شیوع hgv و gbv-c در اهداکنندگان خون درکشورهای توسعه یافته برمبنای تشخیص hgv rna و یا تجسس anti-e2 به ترتیب بین 1% تا 5% و 3% تا 14% می باشد. هدف از این مطالعه بررسی سرواپیدمیولوژیک ویروس هپاتیت (hgv) g در اهداکنندگان خون، بیماران همودیالیز، هموفیل و بتاتالاسمی ماژور دارای سابقه بیماری کبدی در تهران بود. مواد و روش ها در این تحقیق که به روش توصیفی انجام شد، نمونه خون ا...
Introduction: Hepatitis G virus is an RNA virus related to Flaviviridae family that its genome was identified in the patients with non A-E hepatitis at the end of the last century. The present study aimed to investigate the survey of the prevalence of hepatitis G in blood donors and its relation to age and gender Methods: In this descriptive cross-sectional study, sampling was performed on 263...
the hepatitis g virus (hgv) is a newly discovered rna virus, which is associated with acute or chronic hepatitis. a survey was conducted in thalassemic patients, intravenous drug users (ivdu) and blood donors aiming to investigate the prevalence of hepatitis g virus (hgv) infection in these groups in tehran. the presence of hgv rna in these populations was determined using reverse transcriptase...
