Certain nondigestible oligosaccharides can be selectively utilized by probiotics and reduce the risk of colon cancer. However, the inhibitory effects of xylooligosaccharides (XOS) on colon cancer are not well documented. This study evaluated the effects of xylooligosaccharides and fructooligosaccharides (FOS) on the alteration of cecal microbiota, cecal pH,(More)
In the present study, we evaluated the beneficial effect of mulberry extracts (ME), which are rich in phenolics and anthocyanins, on the induction of antioxidant enzymes and on the promotion of cognition in senescence-accelerated mice (SAMP). Six-month old SAMP8 and SAMR1 mice were fed a basal diet supplemented with 0.18% and 0.9% ME for consecutive 12(More)
Effects of C-phycocyanin (C-PC), the active component of Spirulina platensis water extract on the expressions of N-methyl D-aspartate receptor subunit 2B (NR2B), tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), and cyclooxygenase type 2 (COX-2) genes in the cochlea and inferior colliculus (IC) of mice were evaluated after tinnitus was induced by(More)
The present study was carried out to explore the effects of oolong and green teas on improving the memory deficits and brain pathological changes in senescence accelerated-prone mice P8 (SAMP8). Six-month-old mice were supplied with oolong tea, green tea or water as the sole drinking fluid for 16 wk. The memory ability of mice was evaluated by passive and(More)
Changes in the gene expressions for tumor necrosis factor-α (TNF-α) and/or interleukin-1β (IL-1β) during tinnitus have not been previously reported. We evaluated tinnitus and mRNA expression levels of TNF-α, IL-1β, and N-methyl D-aspartate receptor subunit 2B (NR2B) genes in cochlea and inferior colliculus (IC) of mice after intraperitoneal injections of(More)
OBJECTIVE/HYPOTHESIS The expression of the genes for cyclooxygenase (COX) and NMDA receptor (NR) has seldom been reported in tinnitus. We hypothesized that expression of COX-2 and NR was altered in the cochlea and midbrain in salicylate-induced tinnitus. STUDY DESIGN Experimental study on mice. METHODS We evaluated the tinnitus score and mRNA expression(More)
Various formulations of agricultural chemicals, including solutions, wettable powders, and emulsifiable concentrates, contain adjuvants of solvents and surfactants in addition to active ingredients. Among these formulations, herbicides are among the most commonly used pesticides globally. Some pesticides have been demonstrated to cause severe circulatory(More)
Aging is accompanied by pathophysiological changes including insulin resistance and fatty liver. Dietary supplementation with (-)-epigallocatechin-3-gallate (EGCG) improves insulin sensitivity and attenuates fatty liver disease. We hypothesized that EGCG could effectively modulate aging-associated changes in glucose and lipid metabolism in(More)
Soy isoflavones may have applications in cancer prevention and anti-inflammation, therefore this study was conducted to investigate the effect of dietary supplementation with black soybean on the immune response in the senescence-accelerated-prone mice (SAMP8) and -resistant mice (SAMPR1, as controls). The mechanism of isoflavones was also investigated.(More)
Spirulina has proven to be effective in treating certain cancers, hyperlipidemia, immunodeficiency, and inflammatory processes. In this study, we aimed to investigate the effects of Spirulina on memory dysfunction, oxidative stress damage and antioxidant enzyme activity. Three-month-old male senescence-accelerated prone-8 (SAMP8) mice were randomly assigned(More)
