background and aims: the aim of this study was to determine the correlation between the hepatitis b virus surface ag (hbsag) genotypes and variations in the clinical/serological pictures among hbsag positive chronic patients from south khorasan province of iran. methods: twenty-five patients were enrolled in this study. the hbs ag gene was amplified and was directly sequenced. genotypes and nuc...
BACKGROUND AND AIMS Resistance mutation analogs to nucleos(t)ides have been described in treatment-naïve patients with chronic hepatitis B (CHB), with clinical implications. The aim of this study was to investigate primary resistance mutations and genotypes circulating in patients naïve to chronic hepatitis B, in the Northern and Northeastern regions of Brazil. METHODS We conducted a study of...
سندرم تخمدان پلی کیستیک(pcos) اختلال سیستم تولیدمثلی و نارسایی اندوکرینی است که با رشد سریع اولیه ی فولیکولی و عدم انتخاب یک فولیکول غالب از ذخیره ی افزایش یافته ی فولیکولی، هایپراندروژنیسم، افزایش آنژیوژنز، جریان خون تخمدانی و متعاقبا عدم تخمک گذاری مزمن همراه است. این سندرم همچنین به عنوان یک بیماری التهابی با افزایش سطح سیتوکین ها و نیز افزایش crp سرم معرفی شده است. نظر به اثرات آنژیوژنیک سی...
mutations in the human hepatitis b virus (hbv) genome contribute to its escape from host immune surveillance and result in persistent infections. the aim of this study was to characterize the molecular variations of the surface gene and protein in chronically-infected patients from the southern part of iran. the surface genes from 12 hbv chronic carriers were amplified, sequenced and ...
Background: The risk of infection by transfusion-transmitted viruses has been reduced remarkably. However, a zero-risk blood supply is still desirable. The screening for antibody to HBc (anti-HBc) has been shown as an alternative test for the detection of HBV infection. Objective: The main aim of this study was to evaluate HBV infection markers and the potential value of anti-HBc testing of blo...
ABSTRACT One of the best reliable markers of hepatitis B virus infection is antibodies to the core antigen (Anti-HBc). A first-time blood donor with HBsAg positivity was identified as an HBV carrier that was anti-HBc negative. The patient was followed for 24 months in order to investigate the evolution of his HBV serological profiles and HBVDNA (PCR). In the follow-up for 24 months, HBsAg, HBe...
Advanced studies have shown a biological correlation between hepatitis B virus (HBV) and B-cell lymphoma, especially diffuse large lymphoma (DLBCL). Patients with DLBCL infected HBV (HBV-associated DLBCL) are clinically characterized by an advanced clinical stage, poor response to front-line immunochemotherapy regimens, worse prognosis. HBV-associated often exhibits abnormal activation of the n...
Abstract. Information about the spatiotemporal variability of soil moisture is critical for many purposes, including monitoring hydrologic extremes, irrigation scheduling, and prediction agricultural yields. We evaluated temporal dynamics 18 state-of-the-art (quasi-)global near-surface products, six based on satellite retrievals, models without data assimilation (referred to hereafter as “open-...
