Potential effect of compounds isolated from Coffea arabica against UV-B induced skin damage by protecting fibroblast cells.

Ultraviolet (UV) radiation has adverse effects on extracellular matrix (ECM) proteins, leading to formation of wrinkles a hallmark of premature skin aging. The adverse effects of UV radiation are associated with induction of matrix metalloproteinases (MMPs) expression and degradation of collagen and elastin. The present study investigated anti-wrinkle effects of chlorogenic acid (CGA), pyrocatechol (PC) and 3,4,5-tricaffeoyl quinic acid (TCQ), isolated from beans of Coffea arabica, against UV-B stimulated mouse fibroblast cells (CCRF) by measuring expression levels of MMP-1, 3, 9, and type-I procollagen.

Peritoneal dialysis-related peritonitis due to Halomonas hamiltonii: A first case report.

Introduction: Halomonas hamiltonii is a Gram-negative, halophilic, motile, and nonspore-forming rod bacterium. Although most Halomonas sp. are commonly found in saline environments, it has rarely been implicated as a cause of human infection.

Anti-inflammatory Potential of Quercetin-3-O-β-D-("2"-galloyl)-glucopyranoside and Quercetin Isolated from Diospyros kaki calyx via Suppression of MAP Signaling Molecules in LPS-induced RAW 264.7 Macrophages.

Diospyros kaki (DK) contains an abundance of flavonoids and has been used in folk medicine in Korea for centuries. Here, we report for the first time the anti-inflammatory activities of Quercetin (QCT) and Quercetin 3-O-β-("2"-galloyl)-glucopyranoside (Q32G) isolated from DK. We have determine the no cytotoxicity of Q32G and QCT against RAW 264.

[Comparative Study on Bowel Preparation Efficacy of Ascorbic Acid Containing Polyethylene Glycol by Adding Either Simethicone or 1 L of Water in Health Medical Examination Patients: A Prospective Randomized Controlled Study].

Background/aims: There are no studies that looked into the bubble eliminating efficacy of polyethylene glycol with ascorbic acid (PEGA), which has been one of the shortcomings of polyethylene glycol (PEG). In this study, we compared newly introduced PEGA regimen by adding either simethicone or 1 L of water.

Methods: A prospective randomized controlled study was carried out at Dongguk Universtiy Gyeongju Hospital from July 2014 to September 2014.

Scutellaria radix Extract as a Natural UV Protectant for Human Skin.

Ultraviolet (UV) radiation induces oxidative injury and inflammation in human skin. Scutellaria radix (SR, the root of Scutellaria baicalensis Georgi) contains flavonoids with high UV absorptivity and antioxidant properties. The purpose of this study was to examine the potential use of SR extract as an additive in cosmetic products for UV protection.

Physiological activity of irradiated green tea polyphenol on the human skin.

Physiological activity of irradiated green tea polyphenol on the human skin was investigated for further industrial application. The green tea polyphenol was separated and irradiated at 40 kGy by y-ray. For an anti-wrinkle effect, the collagenase inhibition effect was higher in the irradiated sample (65.

Inhibition of enzyme activities and the antiwrinkle effect of polyphenol isolated from the persimmon leaf (Diospyros kaki folium) on human skin.

Background: Many studies have been conducted to find a natural material that has high biologic functions for human skin without any side effects. Persimmon leaf has a substantial amount of tannins in different forms; therefore, it was selected as a target material.

Objective: The biosynthesis rate of the collagen was also investigated to clarify the beneficial functions for the human skin.
