Antioxidant and Anti-Melanogenesis Effects of Colloidal Gold L. Extracts.

Green tea extract derived from the leaves of L. (CS), is a representative beverage with antioxidant, anti-cancer, and anti-viral properties. CS extract is also used in cosmetics.

Morin Induces Melanogenesis via Activation of MAPK Signaling Pathways in B16F10 Mouse Melanoma Cells.

Morin is a well-known flavonoid, and has been reported to have various properties, such as anti-cell death, antioxidant, and anti-inflammatory properties. Although studies on the biochemical and biological actions of morin have been reported, the melanin biosynthesis effects and molecular mechanisms are unknown. In this study, we first found that morin has the effect of enhancing melanin biosynthesis in B16F10 mouse melanoma cells, and analyzed the molecular mechanism.

Effects of Harvest Time on Phytochemical Constituents and Biological Activities of Berry Extracts.

Ginseng () has long been used as a traditional medicine for the prevention and treatment of various diseases. Generally, the harvest time and age of ginseng have been regarded as important factors determining the efficacy of ginseng. However, most studies have mainly focused on the root of ginseng, while studies on other parts of ginseng such as its berry have been relatively limited.

Anti-inflammatory effect of Allium hookeri on carrageenan-induced air pouch mouse model.

Inflammation is a commonly observed immune reaction, and rheumatoid arthritis is a particularly severe inflammatory disease. In this study, we used an air pouch mouse model to evaluate the anti-inflammatory potential of Allium hookeri, which has both been used as a culinary material and a traditional medicine in south-eastern Asia for many years. Allium hookeri suppressed typical symptoms of inflammation, such as condensation of the air pouch membrane, and inhibited the expression of several inducible proinflammatory cytokines such as IL-1β, IL-6, IL-13, and TNF-α.

Safety of 8-weeks oral administration of L.

Recently, worldwide dietary reference intakes have been considered an important guideline for public health. Some governments and the World Health Organization (WHO) provide guidelines concerning dietary intake. Although an ingredient may have a history of use as a culinary material, changes in the environment over time suggest that the acceptable maximum intake each of food/culinary material should be regularly evaluated.

Recombinant Human Acidic Fibroblast Growth Factor (aFGF) Expressed in Nicotiana benthamiana Potentially Inhibits Skin Photoaging.

Responding to the need for recombinant acidic fibroblast growth factor in the pharmaceutical and cosmetic industries, we established a scalable expression system for recombinant human aFGF using transient and a DNA replicon vector expression in . Recombinant human-acidic fibroblast growth factor was recovered following infiltration of . The optimal time point at which to harvest recombinant human acidic fibroblast growth factor expressing leaves was found to be 4 days post-infiltration, before necrosis was evident.
