Anthocyanin, a phenolic compound, has been reported to have an anti-inflammatory effect against lipopolysaccharide (LPS) induced changes in immune cells. However, little is known about the molecular mechanisms underlying its anti-inflammatory effects. Few research studies have concerned the anti-inflammation properties of colored rice extract as a functional material. Therefore, the purpose of this study was to examine anti-inflammatory effects of the polar fraction of black rice whole grain extracts (BR-WG-P) that features a high anthocyanin content. Our results showed that BR-WG-P significantly inhibited LPS-induced pro-inflammatory mediators, including production of NO and expression of iNOS and COX-2. In addition, secretion of pro-inflammatory cytokines including TNF-${\alpha}$ and IL-6 was also significantly inhibited. Moreover, BR-WG-P and anthocyanin inhibited NF-kB and AP-1 translocation into the nucleus. BR-WG-P also decreased the phosphorylation of ERK, p38 and JNK in a dose dependent manner. These results suggested that BR-WG-P might suppress LPS-induced inflammation via the inhibition of the MAPK signaling pathway leading to decrease of NF-kB and AP-1 translocation. All of these results indicate that BR-WG-P exhibits therapeutic potential associated with the anthocyanin content in the extract for treating inflammatory diseases associated with cancer.

Background and Objective: Coptidis Rhizoma is a medicinal herb known for its antioxidant and anti-inflammatory effect. The purpose of this study was to examine the effects of CR on the experimental burn elicitation in vitro and in vivo. Material and Methods: In order to know the antioxidant effect on skin cell of mice after burn elicitation, superoxide dismutase (SOD) activity was measured. In vitro, the RAW 264.7 macrophage cells were treated with lipopolysaccharides for experimental inflammation. iNOS mRNA expression was observed after CR-treatment. In order to know effects on the skin regeneration in the burned mice, we counted the nitric oxide (NO) in blood. We also observed the histological structure in the epidermal basal layer and the dermal section, and we studied changes of angiogenesis in the capillaries surrounding the basal layer and dermal papilla. The changes of transcription of iNOS mRNA (inducible nitric oxide synthase mRNA) and changes of NF-${\kappa}$B (nuclear factor ${\kappa}$B) p65 positive reaction were also observed to investigate the changes of the stress in the skin. Results: The results indicated that CR has significant effects on the antioxidant effect on skin cells of mice after burn elicitation by increasing SOD activity in the in vitro test. It seemed that CR decreased the amount of NF-${\kappa}$B which induced the iNOS mRNA dose-dependently and suppress activating NO and angiogenesis. Furthermore, CR facilitated the process of skin recovery after experimental burn. Conclusion: CR can be applied for burned skin via antioxidant effect and skin regeneration.

In this study, white ginseng was used as the raw material, which was fermented with Paecilomyces hepiali through solid culture medium, to produce ginsenosides with modified chemical composition. The characteristic chemical markers of the products thus produced were investigated using rapid resolution liquid chromatography coupled with quadrupole time-of-flight mass spectrometry (RRLC-QTOF-MS). Chemical profiling data were obtained, which were then subjected to multivariate statistical analysis for the systematic comparison of active ingredients in white ginseng and fermented ginseng to understand the beneficial properties of ginsenoside metabolites. In addition, the effects of these components on biological activity were investigated to understand the improvements in the phagocytic function of macrophages in zebrafish. According to the established RRLC-QTOF-MS chemical profiling, the contents in ginsenosides of high molecular weight, especially malonylated protopanaxadiol ginsenosides, were slightly reduced due to the fermentation, which were hydrolyzed into rare and minor ginsenosides. Moreover, the facilitation of macrophage phagocytic function in zebrafish following treatment with different ginseng extracts confirmed that the fermented ginseng is superior to white ginseng. Our results prove that there is a profound change in chemical constituents of ginsenosides during the fermentation process, which has a significant effect on the biological activity of these compounds.

Background: Compound K (CK) is a bioactive derivative of ginsenoside Rb1 in Panax ginseng (Korean ginseng). Its biological and pharmacological activities have been studied in various disease conditions, although its immunomodulatory role in innate immunity mediated by monocytes/macrophages has been poorly understood. In this study, we aimed to elucidate the regulatory role of CK on cellular events mediated by monocytes and macrophages in innate immune responses. Methods: The immunomodulatory role of CK was explored by various immunoassays including cell-cell adhesion, fibronectin adhesion, cell migration, phagocytic uptake, costimulatory molecules, reactive oxygen species production, luciferase activity, and by the measurement of mRNA levels of proinflammatory genes. Results: Compound K induced cell cluster formation through cell-cell adhesion, cell migration, and phagocytic activity, but it suppressed cell-tissue interactions in U937 and RAW264.7 cells. Compound K also upregulated the surface expression of the cell adhesion molecule cluster of differentiation (CD) 43 (CD43) and costimulatory molecules CD69, CD80, and CD86, but it downregulated the expression of monocyte differentiation marker CD82 in RAW264.7 cells. Moreover, CK induced the release of reactive oxygen species and induced messenger RNA expression of proinflammatory genes, inducible nitric oxide synthase, and tumor necrosis factor-alpha by enhancing the nuclear translocation and transcriptional activities of nuclear factor kappa-B and activator protein-1. Conclusion: Our results suggest that CK has an immunomodulatory role in innate immune responses through regulating various cellular events mediated by monocytes and macrophages.

Citrus, yield of which is the highest among fruits produced in Korea, is extensively consumed for processed food items. The amount of by-products of citrus produced from the processing within a short period after the harvest is tremendous. These by-products are mostly dumped into land or neglected because of cost involved in processing them. The aim of the present study was to explore the usefulness of the by-products as a new material by examining the anti-inflammatory activity of fermented extracts of citrus peels. The peels of 'unshu' (Citrus unshiu) was fermented with Aspergillus niger and their extracts before or after fermentation were analyzed using HPLC. The analysis showed that neohesperidin level considerably increased and the two new compounds were synthesized after fermentation. The anti-inflammatory activity of the fermented extracts was examined on RAW 264.7 murine macrophage cells stimulated with lipopolysaccharide. Fermented unshu extracts significantly enhanced the decrease of nitric oxide (NO) production, iNOS and COX-2 expression, comparing with those of unfermented extracts. Also TNF-${\alpha}$ and IL-6 production, both of which are pro-inflammatory cytokine, were more inhibited in fermented extracts. These results showed that the fermentation and promotion of the function of the by-products of citrus peels will help find a new application.

Large-scale copy number variants (CNVs) in the human provide the raw material for delineating population differences, as natural selection may have affected at least some of the CNVs thus far discovered. Although the examination of relatively large numbers of specific ethnic groups has recently started in regard to inter-ethnic group differences in CNVs, identifying and understanding particular instances of natural selection have not been performed. The traditional $F_{ST}$ measure, obtained from differences in allele frequencies between populations, has been used to identify CNVs loci subject to geographically varying selection. Here, we review advances and the application of multinomial-Dirichlet likelihood methods of inference for identifying genome regions that have been subject to natural selection with the $F_{ST}$ estimates. The contents of presentation are not new; however, this review clarifies how the application of the methods to CNV data, which remains largely unexplored, is possible. A hierarchical Bayesian method, which is implemented via Markov Chain Monte Carlo, estimates locus-specific $F_{ST}$ and can identify outlying CNVs loci with large values of FST. By applying this Bayesian method to the publicly available CNV data, we identified the CNV loci that show signals of natural selection, which may elucidate the genetic basis of human disease and diversity.

Hydroxyapatite (HAp) and biphasic calcium phosphate (BCP) nano powders were synthesized using the microwave-assisted synthesis process dependent on pH and microwave irradiation time. The average size of a powder was less than 100 nm in diameter. Through in-vitro cytotoxicity tests by an extract dilution method, the HAp and BCP nano powders have shown to be cytocompatible for L-929 fibroblast cells, osteoblastlike MG-63 cells and osteoclast-like Raw 264.7 cells. The activation of osteoblast was estimated by alkaline phosphatase (ALP) activity. When the HAp and BCP were treated to MG-63 cells, alkaline phosphatase activities increased on day 3, compared with those of the untreated cells. Also, the collagen fibers increased when the HAp and BCP powders suspension were treated to MG-63 cells, compared to those of the untreated cells. Quantitative alizarin red S mineralization assays showed a trend toward increasing mineralization in osteoblast cultured with powder suspension. In conclusion, hydroxyapatite and biphasic calcium phosphate appeared to be a bone graft substitute material with optimal biocompatibility and could be further applied to clinical use as an artificial bone graft substitute.

Objectives: FDY003 is a raw material for medicine consisting of a natural product that is expected to have the advantages of low side effects and high efficacy. In this study, we predict the efficacy and the standardization of the drug by method validation of anticipated index compounds and the measurement of antioxidant activity. Methods: FDY003 is prepared by extracting and purifying 70% of ethyl alcohol (EtOH). The method validation of cordycepin and chlorogenic acid was determined by high-performance liquid chromatography-photo diode array (HPLC-PDA) and the content of FDY003 was calculated. In order to monitor the biological activity of FDY003, antioxidant activity was measured by 1,1-diphenyl-2-picrylhydrazyl (DPPH), 2,2-azino bis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS), and ferric-reducing antioxidant power (FRAP). The equivalent values of antioxidants such as trolox, ascorbic acid, gallic acid, and caffeic acid were measured by ABTS and FRAP. Results: Chlorogenic acid and cordycepin were both found suitable for method validation in HPLC and FDY003 containing 9.92±0.50 and 17.97±0.27 ㎍/g, respectively. In DPPH, the electron donating ability (EDA) value of FDY003 was increased in a concentration dependent manner. FDY003 confirmed antioxidant activity by ABTS and FRAP. Conclusions: FDY003 contains certain components including cordycepin and chlorogenic acid and has antioxidant ability by various mechanisms. Therefore, it is expected that FDY003 is capable of various physiological activities including anti-cancer activity.
