Oral candidiasis is often accompanied by severe inflammation, resulting in a decline in the quality of life of immunosuppressed individuals and elderly people. To develop a new oral therapeutic option for candidiasis, a nonpathogenic commensal oral probiotic microorganism, Streptococcus salivarius K12, was evaluated for its ability to modulate Candida albicans growth in vitro, and its therapeut...

We report an electrohydrodynamic effect arising from the application of alternating electric fields to patterned electrode surfaces. The AC fields were applied to dilute suspensions of latex microspheres enclosed between a patterned silicon wafer and an ITO-coated glass slide in a small chamber. The latex particles became collected in the center of the conductive "corrals" on the silicon wafer ...

Objectives: Studies done on the management of oral lichen planus using tacrolimus are limited. The aim of the study is to compare the efficacy of tacrolimus with triamcinolone acetonide topically in the management of symptomatic oral lichen planus and also to evaluate adverse effects and opportunistic yeast infections. Materials and methods: A randomized controlled study was conducted on 60 pat...

Hexokinase is the first enzyme in the glycolytic pathway, catalyzing the transfer of a phosphoryl group from ATP to glucose to form glucose 6-phosphate and ADP. Two yeast hexokinase isozymes are known, namely PI and PII. The crystal structure of yeast hexokinase PII from Saccharomyces cerevisiae without substrate or competitive inhibitor is determined and refined in a tetragonal crystal form at...

Baked goods are among the most important sources of human food. They may suffer from a limited shelf life due to use of low-quality wheat. However, there are a number of novel dough preparation methods that can improve bread quality. The current study analyzed the effect of the yeast-salt method on the physicochemical and rheological properties of toast dough and bread. Baker’s yeast was used a...

In this study, twenty-five whey samples collected from dairy industries in the city of Isfahan. The sampleswere cultured on malt extract broth (MEB) and yeast extract glucose chloramphenicol agar (YGCA) media.Eleven yeast strains (designated M1 to M11) were isolated from the culture. The strains were identified bytheir morphological and physiological properties. Betagalactosid...

A 50-day feeding trial was conducted to evaluate the effects of yeast nucleotide in diets on growth performance, serum immune indices and muscle composition of Ancherythroculter nigrocauda (mean initial body weight, 23.30±0.59 g). Seven isonitrogenous (approximately 42.76% crude protein) and isoenergetic (17.43 KJ g−1 gross energy) experimental diets with varying levels of yeast nucleotide (0[c...

A study of 552 female patients was undertaken to determine the frequency of yeast infections in women attending a V.D. clinic. The findings were as follows: (1) 207 of the 552 (37.5 per cent.) were found to have yeasts. (2) C. albicans accounted for 86 per cent. of these yeasts. (3) There was no difference in incidence related to age or seasonal variation. (4) Oral contraceptives increased the ...

The attachment of microorganisms to a surface is a critical first step of biofilm fouling in membrane processes. The shear-induced detachment of baker's yeast in adhesive contact with a plane glass surface was thus experimentally studied, using a specially designed shear stress flow chamber. The yeast was marketed either as rod-shaped pellets (type I yeast) or as spherical pellets (type II yeas...
