Exposure of cells to ultraviolet B (UVB) radiation can induce production of free radicals and reactive oxygen species (ROS), which damage cellular components. In addition, these agents can stimulate the expression of matrix metalloproteinase (MMP) and decrease collagen synthesis in human skin cells. In this study, we examined the anti-photoaging effects of(More)
In this paper, we present a novel dichromatic-based method for estimating illuminant chromaticity. The proposed method is essentially based on the Dichromatic Slope and Dichro-matic Line Space that we introduce. Dichromatic slope is the slope of the dichromatic line that passes the image chromaticity of a pixel in chromaticity space. It is(More)
The importance of anticancer stem cell research for breast cancer lies in the possibility of providing new approaches for an improved understanding of anticancer activity and cancer treatment. In this study, we demonstrated that the preclinical therapeutic efficacy of combining the multikinase inhibitor sorafenib with(More)
The aim of this study was to determine the in vitro anti-inflammatory effect of hot water extract from Cordyceps militaris fruiting bodies (CMWE) on lipopolysaccharide (LPS)-stimulated nitric oxide (NO) production, tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) release in RAW 264.7 cells. The treatment of macrophages with various concentrations of(More)
BACKGROUND The tumor necrosis factor (TNF) is believed to play an important role in the pathophysiology of osteoarthritis (OA). Evidence shows that genetic polymorphisms make substantial contributions to the etiology of OA. METHODS We investigated the genotypes TNF-α and TNF-β in 301 OA patients and 291 healthy subjects as controls. We employed a(More)
Programmed cell death 6 (PDCD6) plays an important role in apoptotic cell death and tumorigenesis. In this study, we investigated whether PDCD6 contributes to the development and/or progression of gastric cancers. PDCD6 protein expression was examined in 169 advanced gastric cancer specimens by immunohistochemistry and then correlated with clinicopathologic(More)
Resveratrol has received considerable attention as a polyphenol with various biological effects such as anti-inflammatory, anti-oxidant, anti-mutagenic, anti-carcinogenic, and cardioprotective properties. As part of the overall safety assessment of HS-1793, a novel resveratrol analogue free from the restriction of metabolic instability and the high dose(More)
Benign perivascular epithelioid cell tumor (PEComa) of the lung is a rare benign neoplasm, a sclerosing variant of which is even rarer. We present a case of 51-year-old man who was diagnosed with benign sclerosing PEComa by percutaneous fine needle aspiration cytology and biopsy. The aspirate revealed a few cell clusters composed of bland-looking polygonal(More)
This study aimed to elucidate anti-inflammatory activities from extracts of Asterina pectinifera on nitric oxide (NO) production, TNF-α and IL-6 release in lipopolysaccharide (LPS) -stimulated murine macrophage cell, RAW264.7. We prepared the methanolic extracts (60-MAP, 70-MAP, 80-MAP and 90-MAP) , aqueous extract (W-AP) and functional bioactive compound(More)
A 61-year-old woman visited our hospital for bilateral multiple lung nodules and a mass in her thorax. She had a long history of multiple metastatic recurrences of solid pseudopapillary neoplasm (SPN); 24 years previously, the patient had undergone pylorus-preserving pancreaticoduodenectomy for a 9.9 × 8.6 cm mass in the pancreatic head. The tumor was(More)
