Background: Chronic myeloid leukemia is a common cancer in human, so the goal of this study was the use of natural compound such as cell wall obtained from Saccharomyces cerevisiae (S. cerevisiae) and Saccharomyces boulardi (S. boulardi) and zinc nanoparticles on the growth inhibition of K562 cell line. Methods: For cell wall preparation, both yeasts were cultured in a basic medium at a...
Background and Objective: Biofilm formation is an important virulence factor in Staphylococcus aureus. Most infections associated with biofilm of this bacterium are difficult to treat with antibiotics. As yet, a lot of mechanisms have been explained for probiotic yeast functions against bacterial infections, but few studies have been done on their effects on biofilm formation. The aim of this s...
Immune-stimulating complexes (iscoms) have been prepared containing the major S gene products (HBsAg) of the hepatitis B virus genome. Immunization of BALB/c mice with a single dose of hepatitis B iscoms in saline resulted in a high titre antibody response to HBsAg. In contrast, the original HBsAg preparation required an adjuvant to produce equivalent amounts of antibody. Analysis of sera from ...
OBJECTIVE To compare the cost-effectiveness of hepatitis B virus (HBV) control strategies combining universal vaccination with hepatitis B immunoglobulin (HBIG) treatment for neonates of carrier mothers. METHODS Drawing on Taiwan's experience, we developed a decision-analytic model to estimate the clinical and economic outcomes for 4 strategies: (1) strategy V-universal vaccination; (2) strat...
Saccharomyces cerevisiae is the main microorganism responsible for the fermentation of wine. Nevertheless, in the last years wineries are facing new challenges due to current market demands and climate change effects on the wine quality. New yeast starters formed by non-conventional Saccharomyces species (such as S. uvarum or S. kudriavzevii) or their hybrids (S. cerevisiae x S. uvarum and S. c...
The characteristics of 30 carriers with occult hepatitis B virus (HBV) infection (OBI) were compared with those of 30 individuals diagnosed as being HBV carriers at the time of blood donation, 60 asymptomatic carriers, and 60 chronic hepatitis patients. The prevalence of genotype C was significantly higher in carriers with OBIs than in any other HBsAg-positive (HBsAg(+)) group (P < 0.001). Spec...
backgrounds: optimization of microbial compositions and load in live food during the process of bioencapsulation is one of the most important concerns in aquaculture, as it can promote the growth and feeding parameters of fish larvae. objectives: the aim of this study was to determine the growth and feeding performance of persian sturgeon larvae fed with bioencapsulated d. magna with saccharomy...
سبوس گندم با دارا بودن فیبر و املاح بالا از خواص تغذیه ای سودمندی برخوردار است، اما به دلیل حضور ترکیب ضد تغذیه ای به نام اسید فیتیک کاربرد محدودی دارد. در این پژوهش اثر سه آغازگر مختلف تهیه شده از s. cerevisiae ptcc 5052 و l. plantarum ptcc 1058، درجه حرارت (25، 30 و 35 درجه سانتی گراد) و طول زمان تخمیر (0،2، 4، 6 و 8 ساعت) بر مقدار ph ، اسیدیته و غلظت اسید فیتیک سبوس گندم استریل شده بررسی گر...
The aim of this study was to characterize the genetic variants HBV currently circulating in Republic Guinea, based on nucleotide sequences complete virus genome, and analyze clinically significant mutations Core HBsAg regions during monoinfection HBV/HIV coinfection. Materials methods. material represented by 2616 blood serum samples collected from residents Guinea. subjects were examined for p...
