DaVinci SP-based simultaneous bilateral partial nephrectomy from the midline transperitoneal approach: a case report.

While simultaneous bilateral partial nephrectomy with a conventional multiport robot has been consistently reported since the 2010s, the introduction of the DaVinci SP system (Intuitive Surgical, Sunnyvale, CA, USA) could provide a novel way to perform surgery on bilateral kidneys while innovatively reducing the number of incisions. In our first report worldwide, the patient with bilateral small renal mass (2.0 cm for the left and 1.

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.

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.

Quercetin-3-O-β-d-glucopyranosyl-(1 → 6)-β-d-glucopyranoside suppresses melanin synthesis by augmenting p38 MAPK and CREB signaling pathways and subsequent cAMP down-regulation in murine melanoma cells.

In this study, the effect of purified quercetin-3-O-β-d-glucopyranosyl-(1 → 6)-β-d-glucopyranosid (QCGG) on melanogenesis was investigated. QCGG was isolated from the calyx of a traditional Korean medicinal herb, Persimmon (Diospyros kaki). The hypopigmentation effects of QCGG were determined by examination of cellular melanin contents, tyrosinase activity assay, cAMP assay, and Western blotting of α-MSH-stimulated B16F10 mouse melanoma cells.
