BACKGROUND/OBJECTIVES: Myocardial infarction (MI) is caused by extensive myocardial damage attributed to the occlusion of coronary arteries. Our previous study in a rat model of ischemia/reperfusion (I/R) demonstrated that administration of arabinoxylan (AX), comprising arabinose and xylose, protects against myocardial injury. In this study, we undertook to investigate whether psyllium seed husk (PSH), a safe dietary fiber containing a high level of AX (> 50%), also imparts protection against myocardial injury in the same rat model. MATERIALS/METHODS: Rats were fed diets supplemented with PSH (1, 10, or 100 mg/kg/d) for 3 d. The rats were then subjected to 30 min ischemia through ligation of the left anterior descending coronary artery, followed by 3 h reperfusion through release of the ligation. The hearts were harvested and cut into four slices. To assess infarct size (IS), an index representing heart damage, the slices were stained with 2,3,5-triphenyltetrazolium chloride (TTC). To elucidate underlying mechanisms, Western blotting was performed for the slices. RESULTS: Supplementation with 10 or 100 mg/kg/d of PSH significantly reduces the IS. PSH supplementation (100 mg/kg/d) tends to reduce caspase-3 generation and increase BCL-2/BAX ratio. PSH supplementation also upregulates the expression of nuclear factor erythroid 2-related factor 2 (NRF2), and its target genes including antioxidant enzymes such as glutathione S-transferase mu 2 (GSTM2) and superoxide dismutase 2 (SOD2). PSH supplementation upregulates some sirtuins ($NAD^+$-dependent deacetylases) including SIRT5 (a mitochondrial sirtuin) and SIRT6 and SIRT7 (nuclear sirtuins). Finally, PSH supplementation upregulates the expression of protein kinase A (PKA), and increases phosphorylated cAMP response element-binding protein (CREB) (pCREB), a target protein of PKA. CONCLUSIONS: The results from this study indicate that PSH consumption reduces myocardial I/R injury in rats by inhibiting the apoptotic cascades through modulation of gene expression of several genes located upstream of apoptosis. Therefore, we believe that PSH can be developed as a functional food that would be beneficial in the prevention of MI.

The mixotrophic dinoflagellate Cochlodinium polykrikoides was reported to be linked to major fish kills in Korea and Japan since the 1990s. Rapid and sensitive detection of microalgae has been problematic because morphological identification of dinoflagellates requires light microscopic and scanning electron microscopic observations that are time consuming and laborious compared to real-time PCR. To address this issue, a real-time PCR probe targeting the ITS2 rRNA gene was used for rapid detection and quantification of C. polykrikoides. PCR inhibitors in water column samples were removed by dilution of template DNA for elimination of false-negative reactions. A strong association between cell quantification using real-time PCR and microscopic counts suggests that the real-time PCR assay is an alternative method for cell estimation of C. polykrikoides in environment samples.

Purpose: This study was done to investigate the effect of self-esteem on perceived stigma in high school students toward people with disabilities. Methods: The participants in this study were 140 high school students from Gyeonggi Province. Data were collected during May 2013. Structured questionnaires were used for data collection. Data were analyzed using descriptive by statistics, t-test, ANOVA, Pearson correlation coefficients, and simple regression analysis with the SPSS 19.0 program. Results: The major findings of this study are as follows: There was a significant relationship between stigma toward people with disabilities and self-esteem among the high school students (r=-.205, p=.015). There was also a significant relationship between relationships with friends (r=.291, p<.001), health statement (r=.400, p<.001) and self-esteem among the high school students. Self-esteem explained 3.5% of the variance in high school students' stigma toward people with disabilities (F=6.041, p=.015). Conclusion: Findings of this study suggest a need to develop education to increase self-esteem as a strategy to decrease high school students' stigma toward people with disabilities. Also, findings of this study suggest the need for repeated study on the relationship between self-esteem and stigma toward people with disabilities among adults.

The purpose of the study was to evaluate the degree of the marginal leakage of esthetic restorative materials on root caries restoration. 120 cavities were prepared to $90^{\circ}$ butt joint on all margins on the crown and root portion, and divided into 4 groups. The four groups of cavity were filled with Amalgam(Dongmuyung Dental Alloy Co., Ltd, KOREA), Silux$^{(R)}$(3M Co., USA)-Scotch Bond 2$^{(R)}$(3M Co., USA), Silux$^{(R)}$-All Bond$^{(R)}$(BISCO USA), and GC Fuji II$^{(R)}$(G-C Co., JAPAN) respectively. The apical margin of the preparation was finished to leave a flash of restorative material. The coronal margin of the preparation was finished not to leave a flash of restorative material. All specimens were sectioned longitudinally with Isomet Low speed saw(Buether Ltd, USA). The degree of dye penetration was evaluated as the parameter of marginal leakage under the stereoscope. The results were as follows. 1. At the enamel and dentin/cementum margins, the margin were finished to leave a flash of material showed less marginal leakage than that were finished not to leave a flash of material (P<0.001). 2. The enamel margins showed less marginal leakage than the dentin/cementum margins(P<0.001). 3. There was no significant difference in the degree of the marginal leakage between Silux$^{(R)}$-Scotch Bond 2$^{(R)}$ group and Silux$^{(R)}$-All Bond$^{(R)}$ group.

Purpose: This study was to identify the relationship between perceived stress, anger expression, and level of depression in cancer patients. Method: A cross-sectional descriptive study design was used. Data was collected by uestionnaires from 185 in- and out-patients who were diagnosed with cancer at 3 university hospitals and the National Cancer Center using Spielberger et al.’s Anger Expression Scale, Cohen, Kamarch & Mermelstein's Perceived Stress, and Derogatise's SCL-90. The data was analyzed using descriptive statistics, Pearson correlation coefficient, and stepwise multiple regression with SAS/PC. Result: The perceived stress in cancer patients indicated a significant positive correlation to anger-in(r=.288, p=.000), anger-out(r=.232, p=.001), and depression(r=.68, p=.000), but no significant correlation to anger-control. The anger-in of cancer patients showed a significant positive relationship to anger-out(r=.53, p=.000), and depression(r=.383, p=.000), but no significant correlation to anger-control. Anger-out showed a significantly negative correlation to anger-control (r=-.248, p=.001) and a positive correlation to depression (r=.240, p=.001). The most significant predictor which influenced depression in cancer patients was perceived stress, followed by anger-in and hobby, and these factors explained their depression with a variance of 54%. Conclusion: These results suggested that cancer patients with a high degree of perceived stress are likely to be high in anger-out and anger-in. Perceived stress and anger-in are major factors which affect depression in cancer patients.
