results comparative analysis of predicted amino acids in the phylogenetic tree showed high similarity between c. glabrata and s cerevisiae. besides, c. glabrata demonstrated the capability to grow in glucose levels as low as 0.01% in the spot dilution assay. in qrt-pcr analysis, differential expressions were observed in selected genes when c. glabrata was subjected to different glucose concentr...

Saccharomyces cerevisiae and its sibling species Saccharomyces paradoxus are known to inhabit temperate arboreal habitats across the globe. Despite their sympatric distribution in the wild, S. cerevisiae is predominantly associated with human fermentations. The apparent ecological differentiation of these species is particularly striking in Europe where S. paradoxus is abundant in forests and S...

Hepatitis B virus (HBV) infection is frequent among patients with chronic kidney disease (CKD). HBV reactivation after transplant (KT) more common in HBsAg+; however, it can also occur previously infected individuals, particularly those HBsAg negative and total antiHBc positive (HBsAg-/antiHBcT+). However, this population has scarce conflicting data. This study aimed to assess the risk KT recip...

There have been an increasing number of reports of yeast systemic infection involving Saccharomyces cerevisiae strains. The development of a rapid and reliable diagnostic tool is therefore warranted in order to explore the distribution of S. cerevisiae as an opportunistic pathogen in humans. In this study, we designed and validated five primer sets targeting the 26S rRNA gene of S. cerevisiae a...

During hepatitis B virus (HBV) infection, high numbers of non-infectious HBV surface antigen (HBsAg) particles are present in circulation. It is shown here that recombinant HBsAg (rHBsAg) particles, which contain the S protein only, bind almost exclusively to monocytes. Attachment of rHBsAg to the THP-1 pre-monocytic cell line occurs upon 1,25-dihydroxyvitamin D3-induced differentiation. Bindin...

background: chronic myeloid leukemia is a common cancer in human and chemical therapy is a routine method for treatment that has some side effects. 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 iron nanoparticles on the growth inhibition of k562 cell line. method...

This study examines the fermentation of autohydrolyzed and 1-n-butyl-3methylimidazolium acetate (C4mimOAc) pretreated sugarcane bagasse, using four different yeast strains to determine the efficiency of bioethanol production. Three strains of Saccharomyces cerevisiae (S. cerevisiae) and one of Scheffersomyces stipitis (S. stipitis) were employed in this study. It was observed that the sugarcane...

Hepatitis B virus (HBV) infection continues to be a major health problem worldwide. The large-scale immunization programs for persons in high-risk groups, newborns, and adolescents have greatly reduced the incidence of new infection, but the ∼400 million HBV carriers with HBV surface antigen (HBsAg) in the blood remain a burden that will dwindle only within decades. Furthermore, an unknown dise...

Hepatitis B virus (HBV) and hepatitis delta virus (HDV) interplay was investigated by examining liver and serum samples from 21 coinfected and 22 HBV-monoinfected patients with chronic liver disease. Different real-time PCR assays were applied to evaluate intrahepatic amounts of HBV DNA, covalently closed circular DNA (cccDNA), pregenomic RNA (pgRNA), pre-S/S RNAs, and HDV RNA. Besides HBV DNA ...

Saccharomyces cerevisiae cannot produce extracellular lipase and utilize low-cost lipid substrates. This study aimed to express extracellular lipase from Yarrowia lipolytica in S. cerevisiae, construct recombinant oily substrate consumer strains, and compare the roles of native and mutant Y. lipolytica extracellular lipases in S. cerevisiae. The LIP2 gene of Y. lipolytica DSM3286 and its mutant...
