Abstract
Thymus quinquecostatus Celak (TQC) is an aromatic herb, that possesses a wide range of biological properties. In the present study, we investigated the radio-protective effect of TQC water extract (TQCW) in gamma ray-exposed splenocytes, a peripheral immune cell and mice. Our results showed that the treatment with TQCW dose-dependently increased the viability of splenocytes. TQCW significantly increased the proliferation of splenocytes by reducing the production of intracellular reactive oxygen species (ROS) in 2 Gy-exposed splenocytes. Moreover, TQCW enhanced the hemopoietic system as increasing the number of endogenous spleen colony-forming units, and the number and the proliferation of splenocytes in 7 Gy-exposed mice. These results suggest that TQCW protects mice by enhancing the splenocytes proliferation and hemopoietic systems following exposure to gamma rays.

Abstract
Methodologies for synthesizing drug-loaded alginate nanocapsules were optimized and indomethacin and phloroglucinol loading capacities were studied. Their biological effects were studied for ameliorating fine dust (FD) induced detrimental effects in keratinocytes. The 1 % alginate to oil phase ratio of 1:20 was the optimal parameter for water in oil emulsification. The oil phase was optimized to contain sunflower oil: span 80 ratios of 17:3. Nanocapsule drug encapsulation efficiencies were 36.91 ± 5.56 and 32.41 ± 4.05 % respectively for phloroglucinol (EG2P) and indomethacin (EG2I) while the loading capacities were 25.28 ± 3.36 and 23.15 ± 2.84 %. Dried nanocapsules indicated a 40-140 nm diameter range while their hydrodynamic diameter was 989.69 nm at pH 7.0. Nanocapsules swelling was pH-dependent and in releasing media of pH values 4.5, 7.4, and 8.5, the drug release indicated a complex mechanism of swelling, diffusion, and erosion while at pH 2.0 the drug release followed the non-Fickian release. EG2P and EG2I treatment dose-dependently lowered FD-induced intracellular ROS production, apoptosis and inflammatory responses mediated through the NF-κB pathway in FD stimulated HaCaT keratinocytes and reduced epidermal barrier degradation. Further research could investigate the use of this technique in formulating cosmeceuticals containing drug-loaded alginate nanocapsules for achieving controlled release.

Abstract
Sasa borealis (Hack.) Makino & Shibata or broad-leaf bamboo is famous for its richness of bioactive natural products and its uses in traditional medicine for its anti-inflammatory, diuretic, and antipyretic properties and preventive effects against hypertension, arteriosclerosis, cardiovascular disease, and cancer. The present study investigated the antioxidant activity of S. borealis hot water extract (SBH) and its effects in ameliorating hydrogen peroxide-induced oxidative stress, using an African green monkey kidney epithelial cell line (Vero). Known polyphenols in SBH were quantified by HPLC analysis. SBH indicated a dose-dependent increase for reducing power, ABTS+ (IC50 = 96.44 ± 0.61 µg/mL) and DPPH (IC50 = 125.78 ± 4.41 µg/mL) radical scavenging activities. SBH markedly reduced intracellular reactive oxygen species (ROS) generation in the Vero cells and increased the protective effects against H2O2-induced oxidative stress by reducing apoptosis. Other than the direct involvement in neutralizing ROS, metabolites in SBH were also found to induce NRF2-mediated production of antioxidant enzymes, HO-1, and NQO1. These findings imply that S. borealis hot water extract can be utilized to create nutraceutical and functional foods that can help to relieve the effects of oxidative stress in both acute and chronic kidney injury.

Abstract
Basophils and mast cells are characteristic effector cells in allergic reactions. Sargahydorquinoic acid (SHQA), a compound isolated from Sargassum serratifolium (marine alga), possesses various biochemical properties, including potent antioxidant activities. The objective of the present study was to investigate inhibitory effects of SHQA on the activation of human basophilic KU812F cells induced by phorbol myristate acetate and A23187 (PMACI), a calcium ionophore. Furthermore, we confirmed the inhibitory effects of SHQA on the activation of rat basophilic leukemia (RBL)-2H3 cells induced by compound 48/80 (com 48/80), bone marrow-derived mast cells (BMCMCs) induced by anti-dinitrophenyl(DNP)-immunoglobulin E (IgE)/DNP-bovine serum albumin (BSA), DNP/IgE and on the reaction of passive cutaneous anaphylaxis (PCA) mediated by IgE. SHQA reduced PMACI-induced intracellular reactive oxygen species (ROS) and calcium levels. Western blot analysis revealed that SHQA downregulated the activation of ERK, p38, and NF-κB in a dose-dependent manner. Moreover, SHQA suppressed the production and gene expression of various cytokines, including interleukin (IL)-1 β, IL-4, IL-6, and IL-8 in PMACI-induced KU812F cells and IL-4 and tumor necrosis factor (TNF)- α in com 48/80-induced RBL-2H3 cells. It also determined the inhibition of PMACI, com 48/80- and IgE/DNP-induced degranulation by reducing the release of β -hexosaminidase. Furthermore, it attenuated the IgE/DNP-induced PCA reaction in the ears of BALB/c mice. These results suggest that SHQA isolated from S. serratifolium is a potential therapeutic functional food material for inhibiting effector cell activation in allergic reactions and anaphylaxis in animal model.

Abstract
Alginate is a biopolymer used in numerous biomedical applications. The current work describes the purification of alginate from Sargassum horneri and method optimization for formulating drug-loaded microparticles by water-in-oil emulsification/internal gelation. Molecular weights of S. horneri alginate were ranging 50-70 kDa. Among 16 method optimizations, the F4 method was selected for further studies based on shape descriptor parameters which indicated, 0.24 ± 0.01 circularity, 0.80 ± 0.11 roundness, 1.27 ± 0.20 aspect ratio between long and short axis, and less aggregation in PBS. Processing parameters of the F4 method were; CaCO3/alginate ratio of 20/1 (w/w), 5% span 80 in oil (v/v), water/oil phase ratio of 1/20 (v/v), and 1000 rpm emulsification speed. Hollow pores were visible on the surface of dehydrated F4 microparticles. F4 microparticles indicated 41.84 ± 2.93 and 45.86 ± 1.65% encapsulation efficiencies for phloroglucinol (F4P) and indomethacin (F4I) with 32.69 ± 1.35 and 31.69 ± 1.98% loading capacities. These microparticles were found to be desirable for extending drug release over short periods (0-3 days) under pH 2.0-7.4. F4P and F4I were effective in suppressing intracellular reactive oxygen species in FD exposed HaCaT cells while increasing cell viability over 24 - 48 h duration.

Abstract
Recent studies have revealed that marine brown seaweeds contain numerous bioactive compounds which exhibit various bioactivities. The present study investigated the effect of low molecular weight fucoidan (SCF) isolated from Sargassum confusum, a brown alga, on inflammatory responses and oxidative stress in HaCaT keratinocytes stimulated by tumor necrosis factor (TNF)-α/interferon (IFN)-γ. SCF significantly increased the cell viability while decreasing the intracellular reactive oxygen species (ROS) production in TNF-α/IFN-γ-stimulated HaCaT keratinocytes. In addition, SCF effectively reduced inflammatory cytokines (interleukin (IL)-1β, IL-6, IL-8, IL-13, TNF-α, and IFN-γ) and chemokines (Eotaxin, macrophage-derived chemokine (MDC), regulated on activation, normal T cell expressed and secreted (RANTES), and thymus and activation-regulated chemokine (TARC)) expression, by down-regulating the expression of epithelial and epidermal innate cytokines (IL-25, IL-33, and thymic stromal lymphopoietin (TSLP)). Furthermore, SCF suppressed the activation of TNF-α/IFN-γ-stimulated mitogen-activated protein kinase (MAPK) and nuclear factor-κB (NF-κB) signaling pathways, while activating the nuclear factor erythroid 2-related factor 2 (Nrf2)/heme oxygenase-1 (HO-1) signaling pathway. The cytoprotective effect of SCF against TNF-α/IFN-γ stimulation was considerably reduced upon inhibition of HO-1 activity by ZnPP. Overall, these results suggest that SCF effectively suppressed inflammatory responses and oxidative stress in TNF-α/IFN-γ-stimulated HaCaT keratinocytes via activating the Nrf2/HO-1 signaling pathway.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Sargassum horneri (Turner) C. Agardh is well known in East Asia as an edible brown alga rich in bioactive compounds. It has an ethnopharmacological significance in traditional Chinese medicine to treat inflammatory disorders varying from edema, furuncles, dysuria to cardiovascular diseases. AIM OF THE STUDY Surge of fine dust (FD), in densely populated areas, have been reported to cause adverse health conditions ranging from respiratory diseases to inflammatory skin disorders. The current study investigates the protective effects of an ethanol extract from S. horneri (SHE) on FD-induced inflammatory responses and impaired skin hydration in HaCaT keratinocytes. MATERIALS AND METHODS Intracellular reactive oxygen species (ROS) generation was evaluated with the 2',7'-Dichlorofluorescin diacetate (DCFH-DA) stain. Anti-inflammatory properties of SHE in FD-stimulated HaCaT keratinocytes were investigated for the suppression of nuclear factor (NF)-κB and mitogen-activated protein kinase (MAPK) pathways and downregulation of pro-inflammatory cytokines. As a means of studying FD-induced skin barrier disruption and the effects of SHE on stratum corneum hydration-controlling factors, tight junction regulatory mediators, and hyaluronic acid (HA) production were evaluated using keratinocytes. RESULTS SHE suppressed the intracellular ROS production, simultaneously improving cell viability in FD-stimulated keratinocytes. Also, SHE upregulated anti-inflammatory cytokine interleukin (IL)-4 while downregulating inflammatory cytokines IL-1β, IL-6, IL-8, tumor necrosis factor (TNF)-α; epidermal and epithelial cytokines IL-25, IL-33, and thymic stromal lymphopoietin (TSLP); thymus and activation-regulated chemokine (TARC), macrophage-derived chemokine (MDC) and regulated upon activation, normally T-expressed, and presumably secreted expression and suppressed (RANTES) chemokine, MAPK and NF-κB mediators in a dose-dependent manner. Furthermore, SHE ameliorated filaggrin, involucrin, lymphoepithelial Kazal-type-related inhibitor (LEKTI), signifying its beneficial effects on deteriorated skin hydration caused by FD-induced inflammation. SHE further exhibited its skin protective effects regulating the tight junction proteins; Occludin, zonula occludens (ZO)-1, claudin-1, claudin-4, claudin-7, and claudin-23 while increasing the production of HA minimizing skin damage. CONCLUSIONS Anti-inflammatory effects of, SHE against FD-induced keratinocyte inflammation is attributable to the suppression of upstream MAPK and NF-κB mediators. SHE indicated potential anti-inflammatory properties attenuating deteriorated skin barrier function in HaCaT keratinocytes. The effects are attributable to the polyphenols and other antioxidant compounds in SHE. Further studies could envisage the use of SHE for developing rejuvenating cosmetics.

Abstract
The present study aimed to evaluate the protective effect of a methanol extract of Sargassum horneri (SHM), which contains 6-hydroxy-4,4,7a-trimethyl-5,6,7,7a-tetrahydrobenzofuran-2(4H)-one (HTT) and apo-9'-fucoxanthinone, against ultraviolet B (UVB)-induced cellular damage in human keratinocytes and its underlying mechanism. SHM significantly improved cell viability of UVB-exposed human keratinocytes by reducing the generation of intracellular reactive oxygen species (ROS). Moreover, SHM inhibited UVB exposure-induced apoptosis by reducing the formation of apoptotic bodies and the populations of the sub-G1 hypodiploid cells and the early apoptotic cells by modulating the expression of the anti- and pro-apoptotic molecules, Bcl-2 and Bax, respectively. Furthermore, SHM inhibited NF-κB p65 activation by inducing the activation of Nrf2/HO-1 signaling. The cytoprotective and antiapoptotic activities of SHM are abolished by the inhibition of HO-1 signaling. In further study, SHM restored the skin dryness and skin barrier disruption in UVB-exposed human keratinocytes. Based to these results, our study suggests that SHM protects the cells against UVB-induced cellular damages through the Nrf2/HO-1/NF-κB p65 signaling pathway and may be potentially useful for the prevention of UVB-induced skin damage.

Abstract
Fucoidans exhibit a wide range of bioactivities and receive significant attention in functional food and cosmetic research. Industrial applications of fucoidan are limited partially due to high extraction and purification costs. The present study implements an enzyme-assisted extraction and step-gradient ethanol precipitation for fractionating fucoidan from Sargassum coreanum based on its charge and molecular weight and evaluation of ultraviolet B (UVB) protective effects in human keratinocytes (HaCaT). The fucoidan fraction SCOC4 indicated higher fucose and sulfate contents with Fourier-transform infrared and 1H NMR spectral patterns resembling fucoidans. SCOC4 dose-dependently abated UVB-induced keratinocyte damage via suppressing intracellular reactive oxygen species, apoptotic body formation, DNA damage via suppressing mitochondria-mediated apoptosis. UVB-protective effects of SCOC4 were further attributable to the augmentation of nuclear factor erythroid 2-related factor 2 mediated cellular antioxidant defense enzymes. Step-gradient ethanol precipitation was a convenient approach of fractionating fucoidans based on molecular weight and charge (depend on the degree of sulfation). Further evaluation of seasonal variations, biocompatibility parameters, efficacy, and shelf life may widen the use of S. coreanum fucoidans in developing UVB-protective cosmetics and functional foods.

Abstract
Recently evidence linking the effects of fine-dust (FD) on skin inflammation is exaggerating. Fucoidan derived from brown algae has great potential for ameliorating oxidative stress and inflammation. Herein, a fucoidan fraction (SHC4-6) was purified from an enzymatic (Celluclast) extract of an invasive seaweed, Sargassum horneri following gradient ethanol precipitation and anion exchange chromatography. Effectiveness of SHC4-6 in ameliorating FD (from Beijing, China)-induced inflammatory responses in HaCaT keratinocytes and recovery of skin barrier dysfunction was evaluated. SHC4-6 was comprising of sulfated mannofucans with their molecular weights distributed around 45 kDa. SHC4-6 dose-dependently lowered ROS levels in FD-induced HaCaT keratinocytes, ameliorating viability at 50 μg mL-1. SHC4-6 downregulated inflammatory cytokines, tumor necrosis factor-α, interleukin (IL)-1β, -5, -6, -8, -13, interferon-γ, and chemokines, macrophage-derived chemokine, eotaxin, and thymus and activation regulated chemokine by inhibiting mitogen-activated protein kinase and nuclear factor-κB pathways. SHC4-6 treatment ameliorated key tight junction proteins and skin hydration factors, depicting the effects of fucoidan in reducing FD-induced inflammation and skin barrier deterioration. With further studies in place, SHC4-6 could be used as an ingredient for developing cosmetics to relieve FD-induced skin inflammation.

Abstract
Damage from ultraviolet (UV)B exposure is cumulative and proceeds via augmenting cellular oxidative stress. The present study investigates UVB-protective effects of Sargassum confusum derived fucoidans in human keratinocytes. Algae was extracted using Celluclast, and fucoidan fractions were recovered by step gradient ethanol precipitation. Refined fucoidan fractions were treated to human HaCaT keratinocytes and exposed to UVB (50 mJ cm-2). Among fucoidan fractions, SCFC4, the lowest molecular weight (MW) fraction indicated better UVB-protective effects with dose-dependent reduction of intracellular ROS levels, while recovering the cell viability. SCFC4 suppressed UVB-induced apoptotic body formation, sub-G1 cell content, and DNA damage by hindering the mitochondria-mediated apoptotic pathway. Also, SCFC4 repressed upstream mediators of UVB-induced inflammatory responses, which would impair stratum corneum hydration. The above therapeutic effects of SCFC4 could be attributed to suppression of nuclear factor (NF)-κB and mitogen-activated protein kinase (MAPK) pathways while activating nuclear factor erythroid 2-related factor 2 (Nrf2) mediated production of antioxidant enzymes. SCFC4 was identified as a fucoidan (MW ≈ 20 kDa) with a 64.64% fucose and 23.62% sulfate contents. Further analysis of shelf life, safety, and efficacy could promote SCFC4's use as a cosmetic ingredient.

Abstract
Sargassum horneri (S. horneri), an edible brown alga, has been proposed as a functional food with an improvement effect on abnormal skin immune responses. The present study investigates the anti-allergic effect of an ethanol extract from S. horneri (SHE) on immunoglobulin E (IgE)/bovine serum albumin (BSA)-mediated activation in bone marrow-derived cultured-mast cells (BMCMCs) and passive cutaneous anaphylaxis (PCA) reaction in mice. SHE markedly and dose-dependently suppressed the degranulation of BMCMCs by reducing the β-hexosaminidase and histamine release without cytotoxicity. In addition, SHE significantly decreased the FcεRI expression on the surface of BMCMCs and its IgE binding. Moreover, SHE reduced the mRNA expression and the production of allergic cytokines; interleukin (IL)-1β, IL-4, IL-5, IL-6, IL-10, IL-13; interferon (IFN)-γ and/or tumor necrosis factor (TNF)-α; and a chemokine, thymus and activation-regulated chemokine (TARC), by suppressing the activation of Src-family kinases and nuclear factor (NF)-κB signaling. In further study, the application of SHE reduced the PCA reaction in an IgE/BSA-induced type I allergic mice model. Taken together, we suggest that SHE has an anti-allergic effect in type I allergic responses.

Abstract
Ultraviolet B (UVB) can induce oxidative damage to outermost layers of skin causing suntans, sunburns, and, in severe cases, blisters leading to photoaging. Low molecular weight (MW) fucoidan is renowned for possessing enhanced antioxidant activities. The present study discloses the use of step gradient ethanol precipitation in refining fucoidan fractions (SSQC1-SSQC4) from Sargassum siliquastrum and evaluation of their UVB-protective effects in human HaCaT keratinocytes. Among the fractions, SSQC4 indicated the best bioactive effects. 1H NMR, FTIR, monosaccharide composition by HPAEC-PAD analysis, MW estimation by agarose gel electrophoresis were used to characterize the fractions. SSQC4 was comprising of fucoidan, with an estimated MW distribution of 8-25 kDa. Exposure of UVB increased intracellular ROS, DNA damage, loss of mitochondrial membrane potential, apoptotic body formation causing cell death through the mitochondria-mediated apoptosis pathway. SSQC4 treatment could dose-dependently attenuate the ROS levels and suppress mitochondria-mediated apoptosis in UVB exposed keratinocytes. SSQC4 treatment enhanced cellular antioxidant defense by increasing Nrf2 mediated HO-1 generation, which was identified as the cause of observed bioactivities. The safety and stability of SSQC4 could be further evaluated to promote its use as a bioactive natural ingredient in UV-protective cosmetics.

Abstract
The present study investigated the protective effects of Sargassum horneri (S. horneri) ethanol extract (SHE) against atopic dermatitis (AD), known as an abnormal immune response in house dust mite (HDM)/2,4-dinitrochlorobenzene (DNCB)-stimulated NC/Nga mice. The oral administration of SHE attenuated the AD symptoms, including the skin dermatitis severity, transepidermal water loss (TEWL), and ear edema in HDM/DNCB-stimulated mice. Moreover, the histological analysis revealed that SHE improved epidermal hyperplasia and hyperkeratosis, and reduced the dermal infiltrations of mast cells and eosinophils. Moreover, SHE downregulated the expression levels of cytokines (interleukin (IL)-6, IL-10, and interferon (IFN)-γ) and chemokines (Regulated on Activation, Normal T Cell Expressed and Secreted (RANTES), Eotaxin, and Thymus and activation-regulated chemokine (TARC)) by decreasing the expression levels of atopic initiators (IL-25 and IL-33) in HDM/DNCB-stimulated skin. The oral administration of SHE decreased the spleen size, reducing expression levels of AD-related cytokines (IL-4, IL-5, IL-6, IL-10, IL-13, IFN-γ, and TARC) by regulating the expressions of Tbx21 (T-bet), GATA Binding Protein 3 (GATA-3), and Signal transducer and activator of transcription 3 (STAT3). Moreover, SHE significantly attenuated the serum immunoglobulin (Ig)G1 and IgG2a levels in HDM/DNCB-stimulated mice. Collectively, these results suggest that S. horneri could be an ingredient of functional food against abnormal immune response.

Abstract
With the ban of conventional cigarettes from public spaces, electronic cigarette (E-cig) liquids have emerged as a nicotine replacement treatment for smoking cessation. However, consumers possess little knowledge of the ingredients and health effects of E-cig liquids following exposure. This study evaluated hair cell damage and developmental toxicities following gestational exposure to E-cig liquids. Zebrafish embryos were exposed to E-cig liquids at different concentrations (0.1%, 0.2%, and 0.4%). Embryonic developmental toxicity and hair cell damage was evaluated at 6 and 7 d, respectively, after fertilization. The average number of hair cells in the anterior lateral line (ALL) and posterior lateral line (PLL) following E-cig exposure was compared to that of the control. Morphological abnormalities and heart rate were evaluated. E-cig liquids significantly damaged the hair cells in the ALL, compared to the control (control; 52.85 ± 5.29 cells, 0.1% E-cig; 49.43 ± 7.70 cells, 0.2% E-cig; 40.68 ± 12.00 cells, 0.4% E-cig; 32.14 ± 20.75%; n = 29-40; p < 0.01). At high concentrations, E-cig liquids significantly damaged the hair cells in the PLL (control; 36.88 ± 5.43 cells, 0.1% E-cig; 33.06 ± 5.21 cells, 0.2% E-cig; 30.95 ± 8.03 cells, 0.4% E-cig; 23.72 ± 15.53%, n = 29-40; p < 0.01). No morphological abnormalities in body shape, somites, notochord, tail, and pectoral fin were observed; however, abnormalities were observed in the dorsal fin and heart rate at high concentrations. Thus, gestational exposure to E-cigs significantly damaged hair cells in a concentration-dependent manner and induced developmental toxicities to the dorsal fin and heart rate at high concentrations.

Abstract
Lead (Pb) is a toxic environmental pollutant that is frequently present in effluents from urban, mining, and industrial sources. The combinatorial effects of heavy metal exposure and temperature in aquatic organisms have received considerable attention as heat stress occurs simultaneously in conjunction with several contaminants in a natural environment. In this study, we examined the potential effects of Pb exposure in conditions of thermal stress (34 °C) in zebrafish (Danio rerio) embryos. Thermal stress at 34 °C induced a dramatic decrease in the survival rate, although exposure to Pb at 26 °C decreased the survival rate of the embryos. Malformations, such as the curved body shape, were increased in response to exposure to a combination of Pb and heat stress. The combination of Pb and heat stress also caused a decrease in the heart rate. Moreover, Pb and high-temperature exposure induced the upregulation of SOD, CAT, TNF-α, IL-1β, p53, and BAX transcripts, and downregulation of Dnmt1 and Dnmt3b transcripts. Thermal stress enhanced transcriptional responses of eight indicator genes following Pb toxicity. The induction of cell death in response to combined exposures was also confirmed in the body of zebrafish by fluorescence intensity image analysis. These data indicated that thermal stress enhanced the poisonous effects of Pb exposure on antioxidant defense, inflammation, and apoptotic mechanisms. Transcriptional inhibition of DNA methylation-related genes might serve as a crucial factor contributing to the possibility of epigenetic adaptation by altering combined stress. We suggest that a careful evaluation of the potential effects of climate change (especially temperature) should be considered when investigating the toxic levels of metal pollution, such as Pb, in an aquatic environment.

Abstract
Fish are frequently affected by environmental stressors, such as temperature changes and heavy metal exposure, in aquatic ecosystems. In this study, we evaluated the combined effects of cadmium (Cd) toxicity and temperature (rearing temperature of 26 °C and heat stress at 34 °C) on zebrafish (Danio rerio) embryos. The survival and heart rates of zebrafish embryos decreased at relatively high Cd concentrations of 0.07 and 0.1 mg L-1. Abnormal morphology was induced by exposure to a combination of Cd toxicity and heat stress. The yolk sac edema size was not significantly different between the control- and Cd-treated groups. Cd exposure induced reactive oxygen species (ROS) production and cell death in the live zebrafish. High temperature (34 °C) triggered Cd-induced cell death and intracellular ROS production to a greater extent than the rearing temperature of 26 °C. Transcriptional levels of six genes-CAT, SOD, p53, BAX, Dnmt1, and Dnmt3b-were investigated. The mRNA expression of CAT and SOD, molecular indicators of oxidative stress, was increased significantly at 34 °C after Cd exposure. The mRNA expression of CAT was more sensitive to temperature than that of SOD in Cd-treated zebrafish. p53 and BAX, apoptosis-related genes, were upregulated upon combined exposure to high temperature and Cd. In addition, at 34 °C, the expression of Dnmt1 and Dnmt3b transcripts, markers of DNA methylation, was increased upon exposure of zebrafish to all concentrations of Cd. Overall, these results suggest that high temperature facilitates the potential role of Cd toxicity in the transcriptional regulation of genes involved in the antioxidant system, apoptosis, and DNA methylation.

Abstract
Eckol, a precursor compound belonging to the dibenzo-1,4-dioxin class of phlorotannins, is a phloroglucinol derivative that exerts various activities. In the present study, we investigated the antiallergic effects of eckol isolated from the marine brown algae, Ecklonia cava using immunoglobulin E (IgE)/bovine serum albumin (BSA)-stimulated mouse bone marrow-derived cultured mast cells (BMCMC) and a mouse model of anaphylaxis. Eckol inhibited IgE/BSA-induced BMCMC degranulation by reducing β-hexosaminidase release. A flow cytometric analysis revealed that eckol decreases FcεRI expression on cell surface and IgE binding to the FcεRI in BMCMC. Moreover, eckol suppressed the production of the cytokines, interleukin (IL)-4, IL-5, IL-6, and IL-13 and the chemokine, thymus activation-regulated chemokine (TARC) by downregulating, IκB-α degradation and NF-κB nuclear translocation. Furthermore, it attenuated the passive cutaneous anaphylactic reaction induced by IgE/BSA-stimulation in the ear of BALB/c mice. These results suggest that eckol is a potential therapeutic candidate for the prevention and treatment of allergic disorders.

Abstract
We investigated the protective effect of the bioactive compound eckol on inflammatory-related skin lesions in vitro. HaCaT cells were stimulated with tumor necrosis factor-alpha (TNF-α) and interferon-gamma (IFN-γ) mixture, and treated with various concentration of eckol (25, 50, and 100 µg/ml). The expression of pro-inflammatory cytokines and chemokines were analyzed by enzyme-linked immunosorbent assay (ELISA) and reverse transcription polymerase chain reaction (RT-PCR), respectively. Mitogen-activated protein kinase (MAPKs) and nuclear factor-kappa B (NF-κB) signaling pathways regulate immune and inflammation responses. Phosphorylation of MAPKs and NF-κB, indicating activation of respective signaling pathways, was examined by western blot analysis. Treatment of TNF-α and IFN-γ promoted the mRNA expression and production of pro-inflammatory cytokines and chemokines in HaCaT cells. However, eckol significantly suppressed the these mediators. Furthermore, activation of TNF-α/IFN-γ-induced MAPKs and NF-κB signaling pathway was inhibited by eckol treatment. Eckol also hampered the TNF-α/IFN-γ-mediated nuclear translocation of NF-κB p65 in HaCaT cells. Taken together, our findings demonstrate that eckol shows effective protective activity against TNF-α/IFN-γ-induced skin inflammation.

Abstract
The health benefit of brown seaweeds has been proclaimed for centuries, particularly in Asian countries. A brown seaweed Sargassum horneri has been suggested to have immune-boosting and anti-inflammatory/immune-regulatory effects, but their mechanism is still elusive. This study researches the immunological effect of 70% ethanol extract of S. horneri (SHE) on unstimulated and Con A-stimulated murine splenocytes. When treated alone, SHE had an immune stimulatory effect on CD3e+ CD4+ T-helper cells, CD3e+ CD8+ cytotoxic T cells, CD45+ CD11b+ macrophages, Ly-6C+ Ly-6 G+ granulocytes, and Ly6 G- Ly6Clow eosinophils. Furthermore, SHE enhanced wide spectrum of Th cytokines such as TNF-α, IFN-γ (Th1), IL-4, IL-5, IL-13 (Th2), and IL-6 (Th17), which also stimulated the macrophage polarizing cytokines and enhanced macrophage derived cytokine secretion. SHE in Con A (5 μg/mL) stimulated cells decreased T-helper, cytotoxic T cells, granulocytes, eosinophils, and monocytes. These results signify the potential immuno-modulatory effect of SHE which can be developed as a therapeutic agent in immuno-compromised individuals.

Abstract
Endothelial cell dysfunction (ECD) is a broad term, which implies dysregulation of endothelial cell functions. Several factors contribute to ECD including high blood pressure, high cholesterol levels, diabetes, obesity, hyperglycemia, and advanced glycation end products (AGEs). The highly reactive dicarbonyl methylglyoxal (MGO) is mainly formed as byproduct of glycolysis. Therefore, high blood glucose levels result in increased MGO accumulation. Taurine-rich foods are considered to protect against various diseases including vasculopathy and to exert anti-aging effects. Here, we investigated the protective effect of hot water extract of Octopus ocellatus meat (OOM), which contains high amounts of taurine, on MGO-induced cell damage in human umbilical vein endothelial cells and zebrafish embryos. Hot water extract of OOMinhibited MGO-induced cytotoxicity and DNA damage, as well as AGEs accumulation. In addition, hot water extract of OOM protected against vascular damage in zebrafish embryos. These results suggest that hot water extract of OOM possesses protective activity against MGO-induced cytotoxicity in both umbilical vein endothelial cells and zebrafish embryos. Therefore, it could be used as a dietary source of an agent for the prevention of vascular diseases.

Abstract
The loss of pancreatic β-cells plays a central role in the pathogenesis of both type 1 and type 2 diabetes, and many studies have been focused on ways to improve glucose homeostasis by preserving, expanding and improving the function of β-cell. Elevated levels of free fatty acids such as palmitate might contribute to the loss of β-cells. A marine squid, Loliolus beka has long been used as a food in Korea, China, Japan and Europe due to its tender meat and high taurine content. Here, we investigated the protective effects of a hot water extract of Loliolus beka meat (LBM) against palmitate toxicity in Ins-1 cells, a rat β-cell line. Treatment with LBM extract protected against palmitate-induced cytotoxicity and scavenged overproduction of nitric oxide, alkyl, and hydroxyl radicals. In addition, LBM extract protected against palmitate-induced DNA damage and β-cell dysfunction. These findings suggest that LBM protects pancreatic β-cells from palmitate-induced damage. LBM could be a potential therapeutic functional food for diabetes.

Abstract
In this study, we evaluated the protective effects of an aqueous extract from Batillus cornutus meat (BM) against cellular oxidative damage caused by hydrogen peroxide (H2O2) in human hepatocyte, Chang cells. First, we prepared an aqueous extract of BM meat (BMW) showing the highest taurine content among free amino acid contents. BMW led to high antioxidant activity showing 2,2-azino-bis(3-ethylbenzthiazoline)-6-sulfonic acid (ABTS) radical scavenging activity, good reducing power and an oxygen radical absorbance capacity (ORAC) value. Also, BMW improved cell viability that was diminished by H2O2 exposure, as it reduced the generation of intracellular reactive oxygen species (ROS) in Chang cells. In addition, BMW up-regulated the production of antioxidant enzymes, such as catalase and superoxide dismutase (SOD), compared to H2O2-treated Chang cells lacking BMW. Moreover, BMW induced the expressions of nuclear Nrf2 and cytosolic HO-1 in H2O2-treated Chang cells. Interestingly, the treatment of ZnPP, HO-1 inhibitor, abolished the improvement in cell viability and intracellular ROS generation mediated by BMW treatment. In conclusion, this study suggests that BMW protects hepatocytes against H2O2-mediated cellular oxidative damage via up-regulation of the Nrf2/HO-1 signal pathway.

Abstract
Gamma ray irradiation causes immune suppressive responses by inducing oxidative stress such as reduction of cell viability and damages in immune cells. In this present study, we investigated whether Octopus ocellatus meet (OM) consisted of a plentiful taurine has protective effects against damages caused by oxidative stress in murine splenocytes. First of all, we prepared the aqueous extract from OM (OMA) and identified it contained a plentiful taurine content. The result also showed that OMA exhibited the antioxidant activity by scavenging DPPH and ABTS+ radicals and hydrogen peroxide. In addition, OMA improved the cell viability without cytotoxicity in gamma ray-irradiated murine splenocytes. Moreover, OMA significantly reduced the production of reactive oxygen species (ROS) in gamma ray-irradiated splenocytes. In further study, we identified that OMA protected zebrafish embryo via improving the reduced survival rate and decreasing the formation of deformity caused by the exposure of gamma ray irradiation. Also, OMA decreased the production of NO and ROS in gamma ray-irradiated zebrafish embryos as well as the induction of cell death. In these results, this study suggests that the consumption of taurine-rich foods, such as O. ocellatus, may be useful for the useful material for the protection against oxidative stress.

Abstract
Octopus ocellatus, a marine cephalopod distributed in the coast of South Korea, China, Japan and tropical sea, contains high amounts of taurine. In this study, an enzymatic hydrolysate obtained from O. ocellatus meat was evaluated for its antioxidant effects using a human liver cell line and zebrafish embryo model. Enzymatic hydrolysates of the O. ocellatus meat (OOM) were prepared using six different enzymes. Among the enzymatic hydrolysates, Alcalase hydrolysate of OOM (OOMAH) showed the highest scavenging effects against 2,2-diphenyl-1-picrylhydrazyl (DPPH), 2,2-azino-bis(3-ethylbenzthiazoline)-6-sulfonic acid (ABTS) radicals and hydrogen peroxide (H2O2). Moreover, it showed a high oxygen radical absorbance capacity (ORAC). OOMAH treatment effectively reduced the hydroxyl radical-induced DNA damage. OOMAH reduced the production of reactive oxygen species (ROS) in H2O2-treated hepatocytes without cytotoxicity. Furthermore, OOMAH improved the survival rate and reduced the intracellular ROS levels in H2O2-treated zebrafish embryos. Compositional analysis of amino acids indicated a high content of taurine in OOMAH. Current results suggest that OOMAH possesses antioxidant bioactivities and could provide protective effects against H2O2-induced oxidative stress. Therefore, OOMAH might be used as a potential resource of functional foods.

Abstract
In this study, we first evaluated protective effects of Loliolus beka in a human liver cell line and zebrafish embryo model with its anti-oxidant activity. First, we prepared the water extract from L. beka meat (LBMW) at room temperature for 24 h and revealed it consisted of a rich taurine. LBMW exhibited the scavenging effects against 2,2-azino-bis(3-ethylbenzthiazoline)-6-sulfonic acid (ABTS) and 2,2-diphenyl-1-picrylhydrazyl (DPPH) radicals and hydrogen peroxide (H2O2) as well as the high value of oxygen radical absorbance capacity (ORAC). Also, the hydroxyl radical-induced DNA damage was dose-dependently reduced by the treatment of LBMW. In addition, LBMW showed no cytotoxicity and reduced the production of reactive oxygen species (ROS) in H2O2-treated hepatocytes. Moreover, LBMW regulated the expression of an anti-apoptotic molecule, Bcl-2 and the expression of pro-apoptotic molecules, Bax and PARP in H2O2-treated hepatocytes as well as the increment of antioxidant mediated-HO-1 and Nrf2 protein expression. In further study, LBMW improved the survival rate and decreased the production of ROS in H2O2-treated zebrafish embryo model. Therefore, our results suggest that Loliolus beka has protective effects against H2O2-induced oxidative stress and may be used as a potential source for functional foods.

Abstract
Here, the anti-inflammatory effect of Xylose-Taurine reduced (X-T-R), a taurine derivate was investigated in lipopolysaccharide (LPS)-stimulated RAW 264.7 cells. X-T-R reduced the generations of nitric oxide (NO) and prostaglandin E2 (PGE2) induced by the stimulation of LPS in RAW 264.7 by suppressing the protein expression of iNOS and COX-2 known as inflammatory mediators. Also, X-R-T reduced the expression levels of the pro-inflammatory cytokines such as interleukin (IL)-1β, IL-6 and tumor necrosis factor (TNF-α). Moreover, X-T-R inhibited the activation of nuclear factor-κB (NF-κB) and the phosphorylation of inhibitor κB (IκB)-α. In conclusion, these results first indicate that X-T-R inhibits LPS-induced inflammation by regulating the NF-κB signal pathway in macrophages.

Abstract
In this study, Xylose-Taurine reduced (X-T-R) was synthesized to enhance biological activities. Hence, we investigated the hepatoprotective effects of X-T-R against H2O2-induced hepatocyte damage and apoptosis. The results showed that X-T-R led to the cytoprotective effect against H2O2-induced oxidative stress in cultured hepatocytes such as the improvement of cell viability and the reduction of reactive oxygen species (ROS) production. Additionally, pre-treatment with X-T-R increased the expression of nuclear factor erythroid 2-related factor 2 (Nrf2), NAD(P)H dehydrogenase:quinone 1 (NQO1) and heme oxygenase 1 (HO-1) in cultured hepatocytes. Furthermore, X-T-R protected the cells against apoptosis via regulating the expression level of Bcl-2/Bax as well as the activation of caspase-3. According to the results obtained, X-T-R may be a bio-material for the therapy of hepatic diseases.

Abstract
The zebrafish (Danio rerio) is useful and convenient vertebrate models in various studies in human disease and drug discovery. In this present study, we first evaluated whether Xylose-Taurine reduced (X-T-R), a taurine derivate protects zebrafish embryos against oxidative stress caused by AAPH (2,2'-Azobis(2-amidinopropane) dihydrochloride). First of all, we selected the concentration of X-T-R showing no toxicity in zebrafish embryos. We identified that X-T-R significantly increased the survival of zebrafish embryo reduced by treatment of AAPH. Also, X-T-R effectively inhibited the productions of reactive oxygen species (ROS) and nitric oxide (NO) as well as the formation of cell death in zebrafish embryos. Moreover, X-T-R down-regulated the expression levels of Bax, caspase-3, caspase-9 and p53 known as pro-apoptotic molecules, whereas up-regulated those of Bcl-2, an anti-apoptotic molecule in AAPH-treated zebrafish embryos. From these results, this study reveals that X-T-R, a taurine derivate might be a potential protector against various damages caused by oxidative stress.

Abstract
In this study, we synthesized Galactose-Taurine sodium salt (G-T) as a functional food ingredient to enhance biological activities of taurine. Also, anti-inflammatory effects of G-T were investigated in lipopolysaccharide (LPS)-stimulated RAW 264.7 cells. G-T found to reduce the generations of the LPS-stimulated nitric oxide (NO) and prostaglandin E2 (PGE2) via down-regulating the expression levels of inducible NO synthase (iNOS) and cyclooxygenase-2 (COX-2). Also, G-T reduced the secretion of inflammatory cytokines including interleukin (IL)-1β, IL-6 and tumor necrosis factor (TNF-α) in LPS-treated RAW 264.7 cells. Finally, we identified that G-T inhibits the activation of nuclear factor-κB (NF-κB) and the phosphorylation of inhibitor κB (IκB)-α. From these results, this study first suggests that G-T could be considered as an effective anti-inflammatory agent.

Abstract
Taurine, the plentiful amino acids in mammalian cells exerts various biological activities including antioxidant and anti-inflammatory effects. Inflammation can cause several diseases such as cancer, heart disease, rheumatoid arthritis and immune system reactions. Here, we investigated anti-inflammatory effects of Galactose-Taurine sodium salt (Gal-Tau), a newly synthesized taurine derivate in LPS-stimulated zebrafish embryos in vivo model. The result showed that Gal-Tau improved the survival rate and the edema in LPS-treated zebrafish embryos. Also, Gal-Tau effectively reduced the productions of nitric oxide (NO), reactive oxygen species (ROS) and cell death induced by LPS in zebrafish embryos. In addition, Gal-Tau regulated the expression levels of inflammatory mediators such as inducible NOS (iNOS) and cycloxygenase 2 (COX-2) as well as IL-6 and TNF-α, inflammatory cytokines known as important key mediators of inflammation. Taken together, this study first indicates that Gal-Tau could be considered as an effective anti-inflammatory material with its anti-inflammatory activity.

Abstract
OBJECTIVE We investigated the possible association of metabolic syndrome with arterial stiffness and coronary atherosclerosis in non-diabetic, postmenopausal women. METHODS A total of 293 non-diabetic, postmenopausal women who visited the health promotion center for a routine health check-up were included in a cross-sectional study. Arterial stiffness was measured by brachial-ankle pulse wave velocity, and coronary atherosclerosis was detected using 64-row multi-detector computed tomography. RESULTS Women with coronary atherosclerosis had a significantly higher proportion of metabolic syndrome than those without coronary atherosclerosis. The brachial-ankle pulse wave velocity was significantly higher in women who had metabolic syndrome compared to those who had no metabolic syndrome (1567.71 ± 211.81 vs. 1336.75 ± 159.62 cm/s, p < 0.001). In addition, the brachial-ankle pulse wave velocity was shown to increase with increasing number of metabolic syndrome components (p for trend < 0.001). Metabolic syndrome was associated with increased risk of coronary atherosclerosis (adjusted odds ratio 2.38; 95% confidence interval 1.01-5.06), after adjusting for confounding factors. CONCLUSIONS Metabolic syndrome increases the risk of coronary atherosclerosis in postmenopausal women. Increased arterial stiffness may partly explain an increased risk of coronary atherosclerosis in postmenopausal women with metabolic syndrome.

Abstract
The severity of Listeria monocytogenes infections emphasizes the need for prevention or elimination of the pathogen from dairy products. Lactococcus lactis KC24, isolated from kimchi, exhibited an antimicrobial effect against food pathogens, including L. monocytogenes ATCC 15313. Lactococcus lactis KC24 was cultured in a 5-L jar fermenter at 35°C, and bacteriocin activity was maximal at 4 h of incubation and persisted for 20 h. Bacteriocin KC24 was inactivated by protease XIV, indicating that it has a proteinaceous nature. Bacteriocin activity was maintained at pH 3.0 to 9.0 and at temperatures of 50 to 121°C. The mode of inhibition against L. monocytogenes ATCC 15313 was shown to involve a bactericidal effect by treatment with 100 and 200 arbitrary units (AU)/mL of bacteriocin KC24. To test the activity of bacteriocin KC24 in a food product, bacteriocin KC24 and nisin (100 and 200 AU/mL) with 4 log cfu/mL of a mixed culture of L. monocytogenes (ATCC 15313, ScottA, H7962, and H7762) were applied to UHT milk. Compared with the control, treatment with bacteriocin KC24 completely inhibited the growth of L. monocytogenes and resulted in no detectable L. monocytogenes after 14 d at 4°C, whereas nisin moderately inhibited L. monocytogenes, resulting in a final concentration after 14 d at 4°C higher than the initial inoculum. Bacteriocin KC24 may prove useful in improving the safety of dairy products.

Abstract
A simple and accurate method for killer-cell immunoglobulin-like receptor (KIR) genotyping is developed using KIR gene-specific primer extension (GSPE) followed by bead array hybridization (GSPE method). After amplification of exons 4, 5, and 9, KIR GSPE and bead array hybridization were performed to verify the presence or absence of 16 KIR subfamilies. GSPE method was validated with natural killer/KIR reference panel I consisting of 48 cell types provided by 13th International Histocompatibility Working Group (IHWG) and genomic DNA from 17 peripheral blood cells, 8 cell lines, and 8 buccal cells. The results of reference panel from GSPE method were 100% concordant with the IHWG reference typing information. All genomic DNAs except reference panel were typed for KIR genes with sequence-specific primer methods and showed 100% identical typing results using this novel system. In addition, GSPE method can obtain results in 8 h from DNA with 10 ng genomic DNA in a 96-well-based assay format.

Abstract
To evaluate the clinical significance of incidental focal prostate fluorodeoxyglucose (FDG) uptake, we reviewed 18-F-FDG positron emission tomography (PET)/CT scans from 2003 to 2007 and selected cases with focal FDG uptake in prostate. Cases of known prostate cancer were excluded. The maximum standardised uptake value (SUV(max)), site (central or peripheral) and pattern (discrete or ill-defined) of FDG uptake, calcification (present or absent) and prostate volume (<30 or ≥30 cc) were recorded. The PET/CT findings were correlated with serum prostate-specific antigen (PSA) levels, imaging studies, clinical follow-up and biopsy. Of a total of 5119 cases, 63 (1.2%) demonstrated focal FDG uptake in prostate. Eight cases were lost to follow-up. Among the 55 cases with follow-up, malignancy was confirmed by biopsy in 3 (5.4%). The three malignant cases had SUV(max) values of 3.3, 3.6 and 2.3, and all were noted in the peripheral portion of prostate; two of these cases had a discrete FDG uptake pattern, none had calcification corresponding to the FDG uptake area and one had a prostatic volume greater than 30 cc. The mean SUV(max) of 52 benign cases was 3.2 ± 1.7 and focal FDG uptake was noted in the peripheral portion in 34 (65%), 20 (38%) cases showed a discrete FDG uptake pattern, 35 (67%) were accompanied by calcification and 32 (62%) had a prostatic volume greater than 30 cc. The majority of cases demonstrating focal FDG uptake in prostate were benign and no PET/CT finding could reliably differentiate benign from malignant lesions; however, when discrete focal FDG uptake without coincidental calcification is seen, particularly in the peripheral zone of the prostate, further clinical evaluation is recommended.

Abstract
Minimal change disease, the most common cause of idiopathic nephrotic syndrome (INS) in children, has a high relapse rate, with approximately half of patients developing steroid dependency. This study was aimed at determining the predictive risk factors for the development of steroid dependency in children diagnosed with INS. A retrospective study of 123 children with steroid-responsive INS, followed for at least 6 months between December 1974 and December 1999, was conducted. The following parameters were studied as predictors of steroid dependency: age at onset, gender, race, microscopic hematuria at onset, atopy, concomitant upper respiratory tract infections (URTI) during relapses, and days to remission with initial steroid therapy. Of the 91 children who fulfilled the inclusion criteria, 61.5% became steroid dependent. Both univariate and logistic regression analyses revealed that initial remission time of 9 or more days (P=0.02, OR=3.0, 95% CI=1.2-7.9) and concomitant URTI during relapses (P=0.01, OR=3.4, 95% CI=1.3-8.8) were significant predictors of steroid dependency. By identifying those children with predictive factors of steroid dependency, the clinician will be better able to plan the long-term management of these patients and reduce the morbidity seen with the frequent relapses and steroid treatment, in a disease that is otherwise associated with a favorable prognosis.

Abstract
Autologous transplantation is increasingly being used to treat patients with multiple myeloma (MM). Recently, peripheral blood progenitor cell (PBPC) harvest have been preferred over autologous bone marrow (BM) harvests due to reduced engraftment time, ease of attainment, and presumptive reduction of occult tumor involvement. To resolve this latter assumption quantitatively, we have used the unique immunoglobulin (Ig) heavy chain variable region sequence of the patient's myeloma cell as a marker of clonality. Samples from PBPC collections and 'back-up' BM harvests were obtained from 13 patients with MM and analyzed for tumor contamination using patient-specific oligonucleotide primers and the polymerase chain reaction. As expected, the percentage of tumor cells contaminating the BM harvest (median, 0.74%) was higher than in the PBPC specimens (median, 0.0024%). Because of the increased total number of cells required for PBPC transplantation, the increase in total number of contaminating cells in the BM vs PBPC autografts was less pronounced, (BM:PBPC tumor contamination ratios ranging from 0.9 to > 4500; median, 14). This confirms that in most but not all cases unmanipulated PBPC products are preferable over BM harvests as a method of reducing myeloma autograft tumor contamination.
