Structural analysis and prebiotic activity of exopolysaccharide produced by probiotic strain EPS DA-LAIM.

Unlabelled: Exopolysaccharide (EPS)-producing EPS DA-LAIM was isolated from healthy human feces, the structure of purified EPS from the strain was analyzed, and its prebiotic activity was evaluated. The EPS from EPS DA-LAIM is a glucomannan-type heteropolysaccharide with a molecular weight of 407-1007 kDa, and its structure comprises 2-mannosyl, 6-mannosyl, and 2,6-mannosyl residues. The purified EPS promoted the growth of representative lactic acid bacteria and bifidobacterial strains.

Potential Probiotic Properties of Exopolysaccharide-Producing EPS DA-BACS and Prebiotic Activity of Its Exopolysaccharide.

Exopolysaccharide (EPS)-producing EPS DA-BACS was isolated from healthy human feces and its probiotic properties, as well as the structure and prebiotic activity of the EPS from this strain were examined. EPS from EPS DA-BACS had a ropy phenotype, which is known to have potential health benefits and is identified as loosely cell-bounded glucomannan-type EPS with a molecular size of 3.7 × 10 Da.

Comparative microbial communities in tidal flats sediment on Incheon, South Korea.

Coastal ecosystems, play critical ecological roles of which tidal flats are a significant component of coastal wetlands, such as habitat and nutrient cycling in aquatic biology. Microbial communities in tidal flats are known to play vital roles of self-purification. And the microbial ecology of the sediment is easily affected by human activities and pollution.

Macelignan inhibits histamine release and inflammatory mediator production in activated rat basophilic leukemia mast cells.

Type I allergy is characterized by the release of granule-associated mediators, lipid-derived substances, cytokines, and chemokines by activated mast cells. To evaluate the anti-allergic effects of macelignan isolated from Myristica fragrans Houtt., we determined its ability to inhibit calcium (Ca(2+)) influx, degranulation, and inflammatory mediator production in RBL-2 H3 cells stimulated with A23187 and phorbol 12-myristate 13-acetate.

The effects of yellow soybean, black soybean, and sword bean on lipid levels and oxidative stress in ovariectomized rats.

Soy isoflavones have been reported to decrease the risk of atherosclerosis in postmenopausal women. However, the effects of dietary consumption of soybean have not been explored. In this study, we evaluated the effects of consuming yellow soybeans, black soybeans (Glycine max), or sword beans (Canavalia gladiate) on lipid and oxidative stress levels in an ovariectomized rat model.

The effect of 4-hydroxypanduratin A on the mitogen-activated protein kinase-dependent activation of matrix metalloproteinase-1 expression in human skin fibroblasts.

Background: Exposure of ultraviolet (UV) light on the skin induces photoaging associated with up-regulated matrix metalloproteinases (MMPs) activities. The MMP-1 expression due to UV irradiation can be mediated by mitogen-activated protein kinases (MAPKs) such as extracellular signal-regulated kinase (ERK), Jun-N-terminal kinase (JNK) and p38 kinase activation.

Objective: We investigated the effects of 4-hydroxypanduratin A, isolated from Kaempferia pandurata Roxb.

Inhibitory effect of panduratin A on UV-induced activation of mitogen-activated protein kinases (MAPKs) in dermal fibroblast cells.

Exposure of the skin to ultraviolet (UV) induces photoaging associated with up-regulated matrix metalloproteinases (MMPs) activities and decreased collagen synthesis. We previously reported that panduratin A, a chalcone compound isolated from KAEMPFERIA PANDURATA Roxb ., decreased MMP-1 expression in UV-irradiated human skin fibroblasts.
