Extraction of polysaccharides from by fermentation with response surface methodology.

is a kind of traditional Chinese medicine used to treat weak spleens, stomach problems, anemia, and fatigue. Polysaccharide is one of main components of . In this study, response surface methodology (RSM) was used to optimize the extraction parameters of polysaccharides (CPP) by fermentation.

Walnut oil improves spatial memory in rats and increases the expression of acid-sensing ion channel genes Asic2a and Asic4.

Although Walnut oil (WO) has been reported to enhance cognitive function, the underlying molecular mechanisms are not well understood. This study was designed to assess the effects of WO on spatial memory in rats through modulation of the expression of acid-sensing ion channel genes, and . To investigate the effect of WO on cognitive performance, we supplemented the diet of female rats with WO.
