The original hepatitis B virus (HBV) large surface antigen gene was synthesized. In order to optimize the expression of this gene in tomato plants, the tobacco pathogenesis-related protein S signal peptide was fused to the 5' end of the modified gene and the sequence encoding amino acids S, E, K, D, E, and L was placed at the 3' end. The gene encoding the modified HBV large surface antigen unde...
The alcoholic fermentative ability of yeast strains; Saccharomyces cerevisiae (isolated from yam), S. cerevisiae (from sugarcane molasses), S. carlsbergensis (from sugarcane molasses) and S. cerevisiae var. ellipsoideus (from orange juice) were examined on orange juice (Citrus sinensis). The quality of the wine produced on the basis of the acidity, ash content, vitamin C and the alcohol content...
Background and Purpose: Microorganism-based synthesis of nanostructures has recently been noted as a green method for the sustainable development of nanotechnology. Nowadays, there have been numerous studies on the emerging resistant pathogenic bacteria and fungal isolates, the probable inability of bacteria and fungi to develop resistance against silver nanoparticles’ (SNPs) antibacte...
The anti-pre-S antibody in the samples of sera from normal healthy persons and patients with different clinical types of liver diseases due to hepatitis B virus (HBV) infection was detected by a newly established enzyme-linked immunosorbent assay technique. This test is a blocking assay where anti-pre-S antibody in the patient's serum blocks subsequent addition of horse radish peroxidase-labell...
Occult hepatitis B virus infection (HBV) is characterized by HBV DNA positivity but HBV surface antigen (HBsAg) negativity. Occult HBV infection is associated with a risk of HBV transmission through blood transfusion, hemodialysis, and liver transplantation. Furthermore, occult HBV infection contributes to the development of cirrhosis and hepatocellular carcinoma. We recently reported the chara...
هپاتیت b، یکی از شایع ترین عفونت های ویروسی است که عامل ایجاد هپاتیت مزمن، حاد و سرطان کبد در انسان می باشد. امروزه بهترین و مناسب ترین راه درمان و پیشگیری از این بیماری، واکسیناسیون است؛ به سبب هزینه گزاف داروهای شیمیایی، در سال های اخیر گیاهان به عنوان بیورآکتورهای مناسب برای تولید ارزان، انبوه و همچنین ایمنی ترکیبات دارویی و نوترکیب مورد توجه بسیاری از محققان قرار گرفته اند. آنتی ژن سطحی هپا...
BACKGROUND AND AIMS Occult hepatitis B virus infection (OBI) poses a challenge to the safety of blood donation. The prevalence of OBI is not well documented in Indonesia, although this information in such an endemic country is needed. This study was aimed to evaluate the prevalence of occult hepatitis B in blood donors from two cities of Indonesia, and to study the genetic variation and its eff...
How the overlap between the hepatitis B virus (HBV) reverse transcriptase (RT) and HBV S antigen (HBsAg) genes modulates the extent of HBV genetic variability is still an open question, and was investigated here. The rate of nucleotide conservation (≤1% variability) followed an atypical pattern in the RT gene, due to an overlap between RT and HBsAg (69.9% nucleotide conservation in the overlapp...
Wine is produced by one of two methods: inoculated fermentation, where a commercially-produced, single Saccharomyces cerevisiae (S. cerevisiae) yeast strain is used; or the traditional spontaneous fermentation, where yeast present on grape and winery surfaces carry out the fermentative process. Spontaneous fermentations are characterized by a diverse succession of yeast, ending with one or mult...
