CD4(+) T cells are essential for the control of Yersinia enterocolitica (Ye) infection in mice. Ye can inhibit dendritic cell (DC) antigen uptake and degradation, maturation and subsequently T-cell activation in vitro. Here we investigated the effects of Ye infection on splenic DCs and T-cell proliferation in an experimental mouse infection model. We found that OVA-specific CD4(+) T cells had a...

effects of yeast extract (ye) (0, 0.05, 0.1, 0.2, 0.5 and 1%) were investigated on rosmarinic acid (ra) accumulation and tyrosine aminotransferase (tat) gene expression in melissa officinalis seedlings at different time intervals (4 and 17 hours). based on the results, only ye concentrations of 0.05%, 0.1%, and 0.2%, for the 17-hour treatment, significantly stimulated ra biosynthesis pathway. a...

Yd. made up, but at ye. place where Mr. S. recommends me I hope to be able to get one cheaper, I must c...

BACKGROUND Citrus junos Tanaka (yuja), a yellow-coloured citrus fruit has traditionally been consumed in Korea, Japan, and China and has been found effective in preventing certain diseases. However, the inhibitory effect of yuja on hepatic lipid accumulation has not been clearly elucidated thus far. METHODS The inhibitory effect of yuja on hepatic lipid accumulation was investigated in both c...

Background Many studies underline the great benefits of yeast extracts (YE), used as supplements in animal free culture media, on cell growth and recombinant protein production [1,2]. Nevertheless, their unknown composition and batch-to-batch variability of commercial YE remain constraints for industrial processes [3,4]. Consequently, the identification of bioactive YE molecules is challenging ...

The present study investigated the effect of crude extracts from yacon leaves, obtained by aqueous cold (YC) or hot (YH) extraction, or hydroethanolic extraction (YE), on glycemia of the diabetic (induced by streptozotocine, 50 mg/kg, ip) and nondiabetic rats. The animals were treated orally with the extracts (400 mg/kg) or water for 3, 7, 10, and 14 days. After this period, the animals were an...

Addition of 1 g/L yeast extract (YE) to sterile, aerobic (approximately 21% dissolved oxygen) and deoxygenated (<0.0001% dissolved oxygen) natural seawater fixed the corrosion potential (Ecorr) of 316L (UNS S31603) stainless steel. YE contains riboflavin and other B vitamins that can act as redox mediators, sorb to surfaces, and chelate metal ions. As demonstrated, YE alters the pH of buffered ...
