The aims of this study are to investigate the relationships of metabolic syndrome (MetS) with insomnia symptoms and sleep duration in a Chinese adult population.Data from a nationwide epidemiological survey conducted on residents from randomly selected districts in Taiwan in 2007 were used for this cross-sectional population-based study. A total of 4,197 participants were included in this study. Insomnia symptoms, including difficulty initiating sleep (DIS), difficulty maintaining sleep (DMS), early morning awakening (EMA), were assessed using the Insomnia Self-Assessment Inventory questionnaire. Subjects were divided into 3 groups based upon their reported sleep duration (< 7, 7-8, and 9 h per night). Odds ratios (ORs) and 95% confidence intervals (CIs) derived from multivariable logistic regression were used to evaluate the study aims.The endorsement of DIS and DMS were cross-sectionally associated with the MetS after adjustment for sleep duration (OR [95% CI] was 1.24 [1.01-1.51] and 1.28 [1.02-1.61], respectively). In addition, short sleep duration was significantly associated with the prevalence of MetS independent of insomnia symptoms (OR [95% CI] was 1.54 [1.05-2.47]). However, there was no significant combined effect of insomnia symptoms and sleep duration on the prevalence of MetS.The current investigation shows that short sleep duration and insomnia symptoms, specifically DIS and DMS, were significant correlates of MetS. These findings should be replicated in prospective studies using both sleep duration and sleep quality measures.

This study selected 21 representative public sites for the survey of indoor air quality in Tainan area, including hospital, school, fitness center, government office, library, theater, transport station, and supermarket. Indoor air quality was first assessed by direct detection apparatus, including CO 2, CO, HCHO, TVOCs, bacteria, fungi, PM 10, PM 2.5, O 3 and temperature. Based on the results of walk-through detection, the spatial distribution of indoor air contaminants was further measured in a 24 hour period by the EPA standard method. The detailed measurements illustrated HCHO, O 3, PM 10 and PM 2.5 concentrations are lower than the suggested threshold levels in all public sites. CO 2 concentrations at hospitals and school are all exceeding category 1 threshold of 600 ppm. Bacteria exceeding the suggested threshold of 500 CFU/m 3 for category 1 and 1000 CFU/m 3 for category 2 is popular at most public sites. One fitness center was found exceeding the TVOCs threshold of 3 ppm, and outdoor air can be a potential source. The high levels of CO 2 and bacteria were a common indoor air quality problem, and the regulated strategy of crowd control and air conditioning management was required for a healthy indoor environment. © (2011) Trans Tech Publications, Switzerland.

The rapid advance of information technology and its penetration into the core elements of the business model and organizational structures is enabling profound and significant organizational changes. In such a dynamic environment, firms must be able to continually evolve their capabilities to facilitate electronic business (e-business) innovation. Yet, current research pays little attention to the core capabilities that contribute to e-business innovation in general. This research seeks to identify the core capabilities that are necessary for achieving e-business innovation. We propose a tri-core model of e-business innovation adopted from Swanson (1994), which knits together three cores: business technology, the business model and the value network. We use this model initially to specify the functional areas of the capabilities. Based on data collected through an intensive literature review and an exploratory Delphi study, thirteen essential capabilities were considered as the keys to e-business innovation exploitation and exploration. Firms can facilitate their e-business solutions over time through the successful development of these capabilities. These findings provide great insights for practitioners and scholars alike to better understand the core capabilities for achieving e-business innovation. It can also help practitioners form a template of the requisite in-house management for identifying knowledge gaps and developing action plans. © 2011 Elsevier Ltd. All rights reserved.

Many catastrophic disasters have happened in Taiwan over the last decade. As disaster is not a special occurrence but rather a part of the norm, mental rehabilitation should be treated as a mainstream issue in psychiatry. The internalization of emergency psychological interventions is necessary for every mental-health professional. The two primary categories of major manmade disasters in Taiwan over the past decade have been gas explosions and powder burns. Both categories have led to the serious injury of many individuals. The physical deformities and job problems faced by burn patients affect their psychiatric and emotional states both directly and indirectly. The psychiatric comorbidities of burn patients include: major depression, generalized anxiety disorder (GAD), and posttraumatic stress disorder (PTSD), with GAD and PTSD comprising the most significant comorbidities in terms of numbers of diagnoses. To reduce psychological problems in the future, mental-health professionals should use appropriate psychologi cal first aid (PFA) interventions in the early stages of treatment and rehabilitation. Mental rehabilitation is a major and comprehensive rehabilitation process. Mental-health professionals should thus use PFA to treat burn patients as well as provide long-term mental rehabilitation after discharge.

Aging is the most important risk factor in cardiovascular disease (CVD), which is the leading causes of death worldwide and the second major cause of death in Taiwan. The major factor in heart failure during aging is heart remodeling, including long-term stress-induced cardiac hypertrophy and fibrosis. Exercise is good for aging heart health, but the impact of exercise training on aging is not defined. This study used 3-, 12- and 18-month-old rats and randomly divided each age group into no exercise training control groups (C3, A12 and A18) and moderate gentle swimming exercise training groups (E3, AE12 and AE18). The protocol of exercise training was swimming five times weekly with gradual increases from the first week from 20 to 60 min for 12 weeks. Analyses of protein from rat heart tissues and sections revealed cardiac inflammation, hypertrophy and fibrosis pathway increases in aged rat groups (A12 and A18), which were improved in exercise training groups (AE12 and AE18). There were no heart injuries in young rat hearts in exercise group E3. These data suggest that moderate swimming exercise training attenuated aging-induced cardiac inflammation, hypertrophy and fibrosis injuries of rat hearts.

Recently, a survey by the Centers for Disease Control and Prevention (CDC) reported that nearly 90% of U.S. adult smokers began smoking at the age of 18. This demonstrates that the exposure to environmental tobacco smoke (ETS) of youngsters today is changing from passive smoking to active smoking (direct inhalation of tobacco). In the current study, an investigation of ETS exposure in young C57BL mice was conducted. After 6 weeks of ETS exposure, the Sirt-1 protein level was decreased and cardiac autophagy was increased in C57BL mice. Furthermore, the IGF2R cardiac hypertrophy signaling pathway was also triggered, although cardiac apoptosis and hypertrophy were not induced. Youngsters desire to look more mature is one of the psychological factors that impacts smoking amongst young people. Our results suggest that though ETS exposure might cause cardiac autophagy amongst youngsters, the loss of the longevity Sirt-1 protein and the increase in IGF2R cardiac hypertrophy signaling could still promote heart diseases that are age-specific.

Metabolic regulation is inextricably linked with cardiac function. Fatty acid metabolism is a significant mechanism for creating energy for the heart. However, cardiomyocytes are able to switch the fatty acids or glucose, depending on different situations, such as ischemia or anoxia. Lipotoxicity in obesity causes impairments in energy metabolism and apoptosis in cardiomyocytes. We utilized the treatment of H9c2 cardiomyoblast cells palmitic acid (PA) as a model for hyperlipidemia to investigate the signaling mechanisms involved in these processes. Our results show PA induces time- and dose-dependent lipotoxicity in H9c2 cells. Moreover, PA enhances cluster of differentiation 36 (CD36) and reduces glucose transporter type 4 (GLUT4) pathway protein levels following a short period of treatment, but cells switch from CD36 back to the GLUT4 pathway after during long-term exposure to PA. As sirtuin 1 (SIRT1) and protein kinase C (PKC) play important roles in CD36 and GLUT4 translocation, we used the SIRT1 activator resveratrol and si-PKC to identify the switches in metabolism. Although PA reduced CD36 and increased GLUT4 metabolic pathway proteins, when we pretreated cells with resveratrol to activate SIRT1 or transfected si-PKC, both were able to significantly increase CD36 metabolic pathway proteins and reduce GLUT4 pathway proteins. High-fat diets affect energy metabolism pathways in both normal and aging rats and involve switching the energy source from the CD36 pathway to GLUT4. In conclusion, PA and high-fat diets cause lipotoxicity in vivo and in vitro and adversely switch the energy source from the CD36 pathway to the GLUT4 pathway.

Doxorubicin (Dox) is extensively used for chemotherapy in different types of cancer, but its use is limited to because of its cardiotoxicity. Our previous studies found that doxorubicin-induced insulin-like growth factor II receptor (IGF-IIR) accumulation causes cardiomyocytes apoptosis via down-regulation of HSF1 pathway. In these studies, we demonstrated a new mechanism through which anthocyanin protects cardiomyoblast cells against doxorubicin-induced injury. We found that anthocyanin decreased IGF-IIR expression via estrogen receptors and stabilized heat shock factor 1 (HSF1) to inhibit caspase 3 activation and apoptosis of cardiomyocytes. Therefore, the phytoestrogen from plants has been considered as another potential treatment for heart failure. It has been reported that the natural compound anthocyanin (ACN) has the ability to reduce the risk of cardiovascular disease (CVD). Here, we demonstrated that anthocyanin acts as a cardioprotective drug against doxorubicin-induced heart failure by attenuating cardiac apoptosis via estrogen receptors to stabilize HSF1 expression and down-regulated IGF-IIR-induced cardiomyocyte apoptosis.

IGF-IIR plays important roles as a key regulator in myocardial pathological hypertrophy and apoptosis, which subsequently lead to heart failure. Salvia miltiorrhiza Bunge (Danshen) is a traditional Chinese medicinal herb used to treat cardiovascular diseases. Tanshinone IIA is an active compound in Danshen and is structurally similar to 17[Formula: see text]-estradiol (E[Formula: see text]. However, whether tanshinone IIA improves cardiomyocyte survival in pathological hypertrophy through estrogen receptor (ER) regulation remains unclear. This study investigates the role of ER signaling in mediating the protective effects of tanshinone IIA on IGF-IIR-induced myocardial hypertrophy. Leu27IGF-II (IGF-II analog) was shown in this study to specifically activate IGF-IIR expression and ICI 182,780 (ICI), an ER antagonist used to investigate tanshinone IIA estrogenic activity. We demonstrated that tanshinone IIA significantly enhanced Akt phosphorylation through ER activation to inhibit Leu27IGF-II-induced calcineurin expression and subsequent NFATc3 nuclear translocation to suppress myocardial hypertrophy. Tanshinone IIA reduced the cell size and suppressed ANP and BNP, inhibiting antihypertrophic effects induced by Leu27IGF-II. The cardioprotective properties of tanshinone IIA that inhibit Leu27IGF-II-induced cell hypertrophy and promote cell survival were reversed by ICI. Furthermore, ICI significantly reduced phospho-Akt, Ly294002 (PI3K inhibitor), and PI3K siRNA significantly reduced the tanshinone IIA-induced protective effect. The above results suggest that tanshinone IIA inhibited cardiomyocyte hypertrophy, which was mediated through ER, by activating the PI3K/Akt pathway and inhibiting Leu27IGF-II-induced calcineurin and NFATC3. Tanshinone IIA exerted strong estrogenic activity and therefore represented a novel selective ER modulator that inhibits IGF-IIR signaling to block cardiac hypertrophy.

High-calorie diet-induced obesity leads to cardiomyocyte dysfunction and apoptosis. Impaired regulation of epididymal fat content in obese patients has been known to increase the risk of cardiac injury. In our study, a lactic acid bacteria, Lactobacillus reuteri GMNL-263, was evaluated for its potential to reduce body weight and body fat ratio and to prevent heart injury in rats with high-fat diet-induced obesity. Lactic acid bacteria supplementation restored the cardiac function and decreased the physiological changes in the heart of the obese rats. In addition, the Fas/Fas-associated protein pathway-induced caspase 3/e Poly polymerase mediated apoptosis in the cardiomyocytes of the obese rats was reversed in the Lr263-treated rats. These results reveal that fed with Lr-263 reduces body fat ratio, inhibits caspase 3-mediated apoptosis and restores cardiac function in obese rats through recovery of ejection fraction and fractional shortening. Our results indicated that the administration of Lr263 lactic acid bacteria can significantly down-regulate body fat and prevent cardiomyocyte injury in obese rats.
