health promotion behavior of middle aged men and the relationship among the above factors. Methods: Subjects of the research were 325 middle aged men in Korea. The questionnaires were composed of general characteristics, Health Self Rating Scale, FACES-Ⅲ : Family Adaptability & Cohesion Evaluation Scale Ⅲ, Health Promoting Lifestyle Profile. Data were statistically analyzed by t-test, ANOVA, Scheffe test and Pearson’s correlation. Results: Middle aged men whose perceived economic status are low show lower perceived health status than moderate and high (F=3.364, p=.010). Health promotion behavior in the age 40-44 shows lower level than 60-64 (F=2.984, p=.019). Middle aged men who have Economically dependent adult in the first child show higher level in health promotion behavior than who have Middle & High school student in the first child (F=2.468, p=.045). In the middle aged men, perceived health status and family cohesion show positive correlation (r=.341, p<.01). Perceived health status and health promotion behavior show positive correlation (r=.500, p<.01). Family cohesion and health promotion behavior show posotive correlation (r=.564, p<.01). Conclusions: We analyzed influencing factor and a relationship between perceived health status, family cohesion and health promotion behavior. Accordingly, we can think of applying nursing interventions to the middle aged men considering the general characteristics. Also we can think of applying nursing interventions and educations to help them evaluate their perceived health status and include the support of family members for the health promotion behavior.

<P><B>Abstract</B></P> <P>Particulate matter (PM) air pollution has gradually become a widespread problem in East Asia. PM may cause unfamiliar inflammatory responses, oxidative stress, and pulmonary tissue damage, and a comprehensive understanding of the underlying mechanisms is required in order to develop effective anti-inflammatory agents. In this study, fine dust collected from Beijing, China (CPM) (size < PM13 with majority < PM2.5) was evaluated for its oxidative stress- and inflammation-inducing effects, which cause cell damage, in A459 human lung epithelial cells. Oxidative stress was marked by an increase in intracellular ROS levels and the production of antioxidant enzymes such as superoxide dismutase (SOD), catalase (CAT), and heme oxygenase-1 (HO-1). Upon induction of oxidative stress, a marked increase was observed in the expression of key inflammatory mediators such as COX-2 and PGE<SUB>2</SUB> and the pro-inflammatory cytokines TNF-α and IL-6 via NF-kB and MAPK pathways. Cellular damage was marked by a reduction in viability, increased lactate dehydrogenase (LDH) release, formation of apoptotic and necrotic bodies, accumulation of sub-G1 phase cells, and DNA damage. Apoptosis was found to be mediated via the activation of caspases through the mitochondria-mediated pathway. Fucosterol, purified from the brown alga <I>Sargassum binderi</I> (Sonder ex J. Agardh) by bio-assay-guided fractionation and purification, exhibited potential therapeutic effects against CPM-induced detrimental effects. Further studies could focus on developing fucosterol, in forms such as steroidal inhalers, against PM-induced pulmonary tissue inflammation.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Fine dust air pollution is a major reason of pulmonary complications in East Asia. </LI> <LI> Dust particles induce oxidative stress and inflammation damaging the lung epithelial cells. </LI> <LI> Fucosterol suppressed the dust induced cell damage by inhibiting oxidative stress and inflammation. </LI> <LI> Fucosterol may have beneficial effects in alleviating adverse respiratory effects of air pollution. </LI> </UL> </P> <P><B>Graphical abstract</B></P> <P>[DISPLAY OMISSION]</P>

Dynamic changes in spindle structure and function are essential for maintaining genomic integrity during the cell cycle. Spindle dynamics are highly dependent on several microtubule-associated proteins that coordinate the dynamic behavior of microtubules, including microtubule assembly, stability and organization. Here, we show that translationally controlled tumor protein (TCTP) is a novel microtubule-associated protein that regulates spindle dynamics during meiotic maturation. TCTP was expressed and widely distributed in the cytoplasm with strong enrichment at the spindle microtubules during meiosis. TCTP was found to be phosphorylated during meiotic maturation, and was exclusively localized to the spindle poles. Knockdown of TCTP impaired spindle organization without affecting chromosome alignment. These spindle defects were mostly due to the destabilization of the polar microtubules. However, the stability of kinetochore microtubules attached to chromosomes was not affected by TCTP knockdown. Overexpression of a nonphosphorylable mutant of TCTP disturbed meiotic maturation, stabilizing the spindle microtubules. In addition, Plk1 was decreased by TCTP knockdown. Taken together, our results demonstrate that TCTP is a microtubule-associating protein required to regulate spindle microtubule dynamics during meiotic maturation in mouse oocytes.

Cyclooxygenase (COX) and 5-lipoxygenase (5-LOX), which play pivotal roles in atherogenesis, have been reported to be involved in plaque stability. Licofelone, a dual COX and 5-LOX inhibitor, has been reported to possess anti-atherogenic effect in rabbit atherosclerosis model. We therefore investigated the anti-atherogenic effect of BHB-TZD [5-(3,5-di-tert-butyl-4-hydroxybenzylidene)thiazolidin-2,4-dione], a dual COX and 5-LOX inhibitor, in low density lipoprotein receptor null (LDLR-/-) mice. Fifteen LDLR-/- mice were fed a western diet (control group), whereas 15 were fed a western diet plus 0.1% (w/w) BHB-TZD (BHB-TZD group). After 8 weeks, the BHB-TZD group had markedly lower serum levels of leukotriene B<SUB>4</SUB> and prostaglandin E<SUB>2</SUB> than the control group. Interestingly, BHB-TZD treatment also reduced plasma triglyceride level without significant changes in total cholesterol and HDL levels. Compared with control mice, BHB-TZD fed mice had 52% fewer fatty streak lesions in the aortic sinus, as well as fewer initial lesions in the aortic arch. Macrophage infiltration into the lesions was 40% lower, and collagen and smooth muscle cells were increased by 102% and 96%, respectively, in the BHB-TZD group compared with the control group. In addition, aortic expression of proatherogenic molecules including TNF-α, IL-1β, IL-6, MCP-1 and VCAM-1, was lower in the BHB-TZD group than the control group. BHB-TZD treatment also reduced MMP-2 and MMP-9 expressions in aorta. In conclusion, BHB-TZD effectively attenuated atherosclerosis in mouse model, suggesting its therapeutic potential for atherosclerosis.
S6K1 Phosphorylation of H2B Mediates EZH2 Trimethylation of H3: A Determinant of Early Adipogenesis
Yi, S.,Um, S.,Lee, J.,Yoo, J.,Bang, S.,Park, E.,Lee, M.,Nam, K.,Jeon, Y.,Park, J.,You, J.,Lee, S.J.,Bae, G.U.,Rhie, J.,Kozma, Sara C.,Thomas, G.,Han, J.W. Cell Press 2016 Molecular Cell Vol.62 No.3
S6K1 has been implicated in a number of key metabolic responses, which contribute to obesity. Critical among these is the control of a transcriptional program required for the commitment of mesenchymal stem cells to the adipocytic lineage. However, in contrast to its role in the cytosol, the functions and targets of nuclear S6K1 are unknown. Here, we show that adipogenic stimuli trigger nuclear translocation of S6K1, leading to H2BS36 phosphorylation and recruitment of EZH2 to H3, which mediates H3K27 trimethylation. This blocks Wnt gene expression, inducing the upregulation of PPARγ and Cebpa and driving increased adipogenesis. Consistent with this finding, white adipose tissue from S6K1-deficient mice exhibits no detectable H2BS36 phosphorylation or H3K27 trimethylation, whereas both responses are highly elevated in obese humans or in mice fed a high-fat diet. These findings define an S6K1-dependent mechanism in early adipogenesis, contributing to the promotion of obesity.
MoO<sub>3</sub>/SiO<sub>2</sub> catalysts for double bond migration of 2-butene
Park, Y.K.,Kim, S.J.,You, N.,Cho, J.,Lee, S.J.,Lee, J.H.,Jeon, J.K. Korean Society of Industrial and Engineering Chemi 2011 Journal of industrial and engineering chemistry Vol.17 No.2
The objective of the present study is to investigate the performance of MoO<SUB>3</SUB>/SiO<SUB>2</SUB> as a catalyst for double bond migration from 2-butene to 1-butene. The effects of MoO<SUB>3</SUB> addition on catalytic properties over SiO<SUB>2</SUB> were analyzed through BET surface area, XRD, ammonia-temperature programmed desorption (NH<SUB>3</SUB>-TPD) and FT-IR of adsorbed pyridine. The highest activity of the 10% MoO<SUB>3</SUB>/SiO<SUB>2</SUB> catalyst in double bond migration of 2-butene can be explained by the highest number of the weak acid sites. Based on the NH<SUB>3</SUB> TPD and the FT-IR of pyridine adsorption results, the increase in the overall number of acid sites can be ascribed to an increase in the number of Lewis sites by the addition of MoO<SUB>3</SUB>3.
