Insulin sensitivity improvement of fermented Korean Red Ginseng (Panax ginseng) mediated by insulin resistance hallmarks in old-aged ob/ob mice.

Background: The biological actions of various ginseng extracts have been studied for treating obesity and diabetes mellitus. However, few studies have evaluated the effects of fermented Korean Red Ginseng (Panax ginseng Meyer) on metabolic syndrome. The present study evaluated the antiobesity and antidiabetic effects of fermented red ginseng (FRG) on old-aged, obese, leptin-deficient (B6.

Optical imaging of absorption and distribution of RITC-SiO2 nanoparticles after oral administration.

Purpose: In this study, we investigated the absorption and distribution of rhodamine B isothiocyanate (RITC)-incorporated silica oxide nanoparticles(SiNPs) (RITC-SiNPs) after oral exposure, by conducting optical imaging, with a focus on tracking the movement of RITC-SiNPs of different particle size and surface charge.

Methods: RITC-SiNPs (20 or 100 nm; positively or negatively charged) were used to avoid the dissociation of a fluorescent dye from nanoparticles via spontaneous or enzyme-catalyzed reactions in vivo. The changes in the nanoparticle sizes and shapes were investigated in an HCl solution for 6 hours.

Effect of Phellinus baumii-Biotransformed Soybean Powder on Lipid Metabolism in Rats.

In this study, we evaluated the hypolipidemic and antioxidative effects of biotransformed soybean powder (BTS; Phellinus baumii-fermented soybean) on lipid metabolism in rats. Sprague-Dawley (SD) male rats were divided into basal diet group (BA), high fat diet group (HF), high fat diet containing 10% BTS group (10 BTS), and high fat diet containing 20% BTS group (20 BTS). Changes in the content of various isoflavones, including daidzein and genistein, within the soybean after fermentation to BTS were investigated.

Walnut extract exhibits anti-fatigue action via improvement of exercise tolerance in mice.

This study was conducted to investigate the anti-fatigue effect of walnut extract (WE) on forced swimming capacity in mice. Twenty-eight male ICR mice were randomly divided into four groups, a vehicle control (VC) or one of three WE administered groups (300, 600 and 900 mg/kg/day). WE was orally administered to mice once a day for 4 weeks, during which time a forced swimming test was conducted once a week.

The butanol fraction of Eclipta prostrata (Linn) increases the formation of brain acetylcholine and decreases oxidative stress in the brain and serum of cesarean-derived rats.

Eclipta prostrata has been used as a traditional medicinal plant to prevent dementia and to enhance memory in Asia. Its potential as a nootropic and as an antioxidant have been reported in mice. We hypothesized that Eclipta may affect the formation of neurotransmitters and the inhibition of oxidative stress.

Inhibitory effect of immature plum on PMA-induced MMP-9 expression in human hepatocellular carcinoma.

The goal of this study was to evaluate the anticancer effect of Prunus salicina Lindl. cv. Soldam at three maturity stages (immature, midmature and mature).

The butanol fraction of Eclipta prostrata (Linn) effectively reduces serum lipid levels and improves antioxidant activities in CD rats.

Eclipta prostrata (Linn) has been used as a traditional medicinal plant to prevent lipidemia and atherosclerosis in Asia. However, its functional properties and the underlying mechanism of action have not been clearly defined. This study was conducted to elucidate the biological basis for hypolipidemic and antioxidant activities of E.
