    The cultural aspects of health promotion are important in policy development as well as in assessing effectiveness of health promotion activities. The discourses on promoting health and well-being in journalism reflect the health promotion culture in society. This article illustrates how health promotion is portrayed by 147 newspaper items from the two Finnish quality dailies during the period 2002-2004 and introduces a semiotic Actantial Model of Health Promotion (AMHP) for studying health promotion cultures. The most popular news themes on health promotion were physical and social environment, welfare services, nutrition and obesity, and mental well-being. The actants (actors, actions and abstract factor) of health promotion were identified and the AMHP with seven key actants (generator, health-object, public, tool, executor, threat and obstacle) was constructed. The model sheds light on two sides of health promotion discourses in journalism. The dominant culture of health promotion was represented by policy actions, information, education and scientific research, which were defined by health experts, decision-makers and researchers. Representations of the opposite culture--'the otherness' of health promotion included external harmful factors and unhealthy behaviours, mentalities opposed to being health-oriented, rationally uncontrolled living, disorder, disharmony and insecurity. The opposing factors were presented by people and institutions lacking the will, ability or motivation for a health-oriented life. To understand better the values of health promotion, it is necessary to assess the characteristics of the opposite side of health promotion culture, because the current dominant values can be described more clearly by the boundaries--by 'otherness'. The study argues that the AMHP can be used as a semiotic method to identify the value dimensions and the boundaries between the dominant and the opposite discourses of health promotion in various communications

    The purpose of this study was to investigate the factors influencing health promoting lifestyle in the elderly. The subject of this study was 305 elderly person over the age of 60, living in rural and urban, Korea. For the analysis of collected data, descriptive statistics, t-test, analysis of variance and stepwise multiple regression were used for statistical analysis with SPSS statistical program. The average item score for the health promoting lifestyle was 2.46. The higher score on the subscale was nutrition(2.65). The lowest score on the subscale were physical activity(2.36) and stress management(2.36). General characteristics showing statistically significant difference in health promoting lifestyle were age, residential district, live together spouse, education, religion and pocket money in the elderly. Stepwise multiple regression analysis revealed that the most powerful predictor of health promoting lifestyle in the elderly was prior related behavior(R2=.554). A combination of prior related behavior, perceived benefits of action, perceived self-efficacy, commitment to a plan of action, and interpersonal influences accounted for 64.3% of the variance in health promoting lifestyle in the elderly. The factors influencing on health promoting lifestyle for elderly were prior related behavior, perceived benefits of action, perceived self-efficacy, commitment to a plan of action, and interpersonal influences.

    Full Text Available Chinese responsibility for reducing Greenhouse Gas or carbon dioxide emission increases continuously. Chinese government suggested two targets; Alternative Fuel Vehicle output volume 500 thousand and AFV market share 5% by the end of 2011. However any of two targets did not come true. Therefore this study accessed the question, ‘why Chinese government initiative model for AFV promotion has been so poor?’ This study reviewed the transition process for AFV policies in China and made a structural analysis for three key policies since 2009. As a result the number of articles for related industries or factor endowments was relatively more than firm strategy or demand conditions. Also this study accessed the AFV strategy of Six SOEs from the perspective of social responsibility. Six SOEs have more concentrated on electric vehicle rather than hybrid vehicle with following the government leadership. However major EV or HEV models of them mostly were made by Joint Ventures being under control of foreign makers and the JVs have actually controlled over AFV business. So the limitation of Chinese government initiative model resulted from supplier-centric approach with targeting for public transportation and institution consumer, and it caused a failure to create the demand conditions of general customers.

    Full Text Available Building on a case study of three animation companies in the Chinese cultural and creative industry, this study aims to understand how profit model innovation is promoted. Due to the rapidly changing environments and resource scarcity, cultural and creative companies need to select the appropriate profit model according to their own key resources. The study uncovers two critical factors that promote profit model innovation in animation projects: the quantity of consumers and their consumption intention. According to these two dimensions, the authors’ analysis shows profit model innovation in animation projects can be divided into Fans mode, Popular mode, Placement mode, and Failure mode, respectively. This study provides an empirical basis for advocating profit model innovation and discusses the resource requirements of Fan mode, Popular model, and Placement mode in China’s cultural and creative industry. The authors’ research also has managerial implications that might help firms promote profit model innovation. Finally, learning and promoting the profit model of China’s animation industry in the Northeast Asia area will be conducive to Northeast Asia’s cooperation and sustainable development.

    Full Text Available BACKGROUND: Physical inactivity is a key risk factor for chronic disease, but a growing number of people are not achieving the recommended levels of physical activity necessary for good health. Australians are no exception; despite Australia's image as a sporting nation, with success at the elite level, the majority of Australians do not get enough physical activity. There are many options for intervention, from individually tailored advice, such as counselling from a general practitioner, to population-wide approaches, such as mass media campaigns, but the most cost-effective mix of interventions is unknown. In this study we evaluate the cost-effectiveness of interventions to promote physical activity. METHODS AND FINDINGS: From evidence of intervention efficacy in the physical activity literature and evaluation of the health sector costs of intervention and disease treatment, we model the cost impacts and health outcomes of six physical activity interventions, over the lifetime of the Australian population. We then determine cost-effectiveness of each intervention against current practice for physical activity intervention in Australia and derive the optimal pathway for implementation. Based on current evidence of intervention effectiveness, the intervention programs that encourage use of pedometers (Dominant and mass media-based community campaigns (Dominant are the most cost-effective strategies to implement and are very likely to be cost-saving. The internet-based intervention program (AUS$3,000/DALY, the GP physical activity prescription program (AUS$12,000/DALY, and the program to encourage more active transport (AUS$20,000/DALY, although less likely to be cost-saving, have a high probability of being under a AUS$50,000 per DALY threshold. GP referral to an exercise physiologist (AUS$79,000/DALY is the least cost-effective option if high time and travel costs for patients in screening and consulting an exercise physiologist are considered

    In the last decades, the epidemiological and demographic transition in Chile has resulted in a considerable increase in diet-related non-communicable chronic diseases. The aim of this study was to determine the impact of a health promotion programme (HPP) on behaviour in terms of the dimensions of the health-promoting lifestyle profile (HPLP) based on Pender's model. Pender based his research on the development of a model that explains, predicts and modifies forms of behaviour that promote health; an HPP based on this model may achieve positive changes that promote a healthy lifestyle. This was a comparative study and the participants were Seventh-Day Adventist Church women (SDAW) and non-Seventh-Day Adventist Church women (NSDAW) aged 20-45 years from the urban area of Villarrica, Ninth Region of Chile. From a population of 300 women (150 SDAW and 150 NSDAW), a random sample of 18 SDAW and 18 NSDAW was chosen. Both groups were comparable in age and socio-economic status. An HPP was undertaken for both groups between April and September 2002. The response rate was 100%. The overall score and the scores for the six dimensions of the HPLP (self-actualization, health responsibility, exercise, nutrition, interpersonal support and stress management) were measured in the pre- and post-test periods. Statistical analysis was performed using the Sign test and Wilcoxon's test. Data were processed using the statistical analysis system. In both groups, the median scores increased significantly between the pre- and post-test periods for the overall HPLP score and the scores of the six dimensions. When comparing the median scores in SDAW with NSDAW, only the score for nutrition was significantly higher in SDAW than NSDAW in both the pre-test (PPender's model improves behaviour related to a health-promoting lifestyle in both groups, but more so for the NASDW.

    Full Text Available The role of the autonomic nervous system (ANS on atrial fibrillation (AF is difficult to demonstrate in the intact human left atrium (LA due to technical limitations of the current electrophysiological mapping technique. We examined the effects of the ANS on the initiation and maintenance of AF by employing a realistic in silico human left atrium (LA model integrated with a model of ganglionated plexi (GPs.We incorporated the morphology of the GP and parasympathetic nerves in a three-dimensional (3D realistic LA model. For the model of ionic currents, we used a human atrial model. GPs were stimulated by increasing the IK[ACh], and sympathetic nerve stimulation was conducted through a homogeneous increase in the ICa-L. ANS-induced wave-dynamics changes were evaluated in a model that integrated a patient's LA geometry, and we repeated simulation studies using LA geometries from 10 different patients.The two-dimensional model of pulmonary vein (PV cells exhibited late phase 3 early afterdepolarization-like activity under 0.05μM acetylcholine (ACh stimulation. In the 3D simulation model, PV tachycardia was induced, which degenerated to AF via GP (0.05μM ACh and sympathetic (7.0×ICa-L stimulations. Under sustained AF, local reentries were observed at the LA-PV junction. We also observed that GP stimulation reduced the complex fractionated atrial electrogram (CFAE-cycle length (CL, p<0.01 and the life span of phase singularities (p<0.01. GP stimulation also increased the overlap area of the GP and CFAE areas (CFAE-CL≤120ms, p<0.01. When 3 patterns of virtual ablations were applied to the 3D AF models, circumferential PV isolation including the GP was the most effective in terminating AF.Cardiac ANS stimulations demonstrated triggered activity, automaticity, and local reentries at the LA-PV junction, as well as co-localized GP and CFAE areas in the 3D in silico GP model of the LA.

    Multiple sclerosis (MS) is a demyelinating neurodegenerative disease, representing a major cause of neurological disability in young adults. Resveratrol is a stilbenoid polyphenol, known to pass blood brain barrier and exhibit antioxidant, anti-inflammatory, and neuroprotective effects in several brain injuries. Cuprizone model of MS is particularly beneficial in studying demyelination/remyelination. Our study examined the potential neuroprotective and pro-remyelination effects of resveratrol in cuprizone-intoxicated C57Bl/6 mice. Mice were fed with chow containing 0.7 % cuprizone for 7 days, followed by 3 weeks on 0.2 % cuprizone diet. Resveratrol (250 mg/kg/day, p.o.) was given for 3 weeks starting from the second week. At the end of the experiment, animals were tested on rotarod to evaluate changes in balance and motor coordination. Mice were then sacrificed to measure the brain content of glutathione, lipid peroxidation products, adenosine triphosphate, and phospho-inhibitory subunit of nuclear factor κB-α. The activities of cytochrome oxidase and superoxide dismutase were also assessed. The gene expression of myelin basic protein, 2',3'-cyclic nucleotide 3' phosphodiesterase, oligodendrocyte transcription factor-1 (Olig1), NF-κB p65 subunit, and tumor necrosis factor-α was also estimated. Luxol fast blue/periodic acid-Schiff stained brain sections were blindly scored to assess the myelin status. Resveratrol effectively enhanced motor coordination and balance, reversed cuprizone-induced demyelination, improved mitochondrial function, alleviated oxidative stress, and inhibited NF-κB signaling. Interestingly, resveratrol increased Olig1 expression that is positively correlated to active remyelination. The present study may be the first to indicate a pro-remyelinative effect for resveratrol which might represent a potential additive benefit in treating MS.

    The gene promoter region controls transcriptional initiation of a gene, which is the most important step in gene regulation. In-silico detection of promoter region in genomic sequences has a number of applications in gene discovery and understanding gene expression regulation. However, computational prediction of eukaryotic poly-II promoters has remained a difficult task. This paper introduces a novel statistical technique for detecting promoter regions in long genomic sequences. A number of existing techniques analyze the occurrence frequencies of oligonucleotides in promoter sequences as compared to other genomic regions. In contrast, the present work studies the positional densities of oligonucleotides in promoter sequences. The analysis does not require any non-promoter sequence dataset or any model of the background oligonucleotide content of the genome. The statistical model learnt from a dataset of promoter sequences automatically recognizes a number of transcription factor binding sites simultaneously with their occurrence positions relative to the transcription start site. Based on this model, a continuous naïve Bayes classifier is developed for the detection of human promoters and transcription start sites in genomic sequences. The present study extends the scope of statistical models in general promoter modeling and prediction. Promoter sequence features learnt by the model correlate well with known biological facts. Results of human transcription start site prediction compare favorably with existing 2nd generation promoter prediction tools.

    Evidence-based interventions are more likely to be adopted if practitioners collaborate with researchers to develop an implementation strategy. This paper describes the steps to plan and execute a strategy, including the development of structure and supports needed for implementing proven health promotion interventions in primary and community care. Between 10 and 13 discussion and consensus sessions were performed in four highly-motivated primary health care centers involving 80% of the primary care staff and 21 community-based organizations. All four centers chose to address physical activity, diet, and smoking. They selected the 5 A's evidence-based clinical intervention to be adapted to the context of the health centers. The planned implementation strategy worked at multiple levels: bottom-up primary care organizational change, top-down support from managers, community involvement, and the development of innovative e-health information and communication tools. Shared decision making and practice facilitation were perceived as the most positive aspects of the collaborative modeling process, which took more time than expected, especially the development of the new e-health tools integrated into electronic health records. Collaborative modeling of an implementation strategy for the integration of health promotion in primary and community care was feasible in motivated centers. However, it was difficult, being hindered by the heavy workload in primary care and generating uncertainty inherent to a bottom-up decision making processes. Lessons from this experience could be useful in diverse settings and for other clinical interventions. Two companion papers report the evaluation of its feasibility and assess quantitatively and qualitatively the implementation process.

    In elementary grades, comprehensive health education curricula have demonstrated effectiveness in addressing singular health issues. The Michigan Model for Health (MMH) was implemented and evaluated to determine its impact on nutrition, physical fitness, and safety knowledge and skills. Schools (N = 52) were randomly assigned to intervention and control conditions. Participants received MMH with 24 lessons in grade 4 and 28 more lessons in grade 5 including material focusing on nutrition, physical fitness, and safety attitudes and skills. The 40-minute lessons were taught by the classroom teacher who received curriculum training and provided feedback on implementation fidelity. Self-report survey data were collected from the fourth-grade students (N = 1983) prior to the intervention, immediately after the intervention, and 6 weeks after the intervention, with the same data collection schedule repeated in fifth grade. Analysis of the scales was conducted using a mixed-model approach. Students who received the curriculum had better nutrition, physical activity, and safety skills than the control-group students. Intervention students also reported higher consumption of fruits; however, no difference was reported for other types of food consumption. The effectiveness of the MMH in promoting fitness and safety supports the call for integrated strategies that begin in elementary grades, target multiple risk behaviors, and result in practical and financial benefits to schools. © 2016, American School Health Association.

    Full Text Available Based on the Stakeholder theory, a moderated mediating effect model is developed to reach the study objective, revealing an important connection that suggests environmental regulations (ERs influence corporate environmental responsibility (CER (Porter Hypothesis. In building the model, the validity of the questionnaire data was analyzed with factor analysis. By employing a two-step approach, a regression analysis is utilized to discuss the mediating effect of altruistic motivation and moderating effect of green innovation, and a structural equation model is used to explore the interactive mechanism of different variables. It is found that altruistic motivation plays a medium role in the relationship between ERs and CER, and green innovation engages a positive coordination in the relationship. The empirical study identifies factors affecting enterprises’ willingness to undertake environmental responsibility, including environment policies, corporate culture, and personal characters among others. It is also revealed that altruistic motivation is conducive to forming a community interests among enterprises and enhancing their resistance to market risks, which explains and corroborates the Stakeholder theory; and the higher the level of green innovation, the more willing enterprises are to implement environmentally friendly operations.

    visualization of large spatial datasets; this is demonstrated by running fourteen case studies using the FREEWAT platform. Among these, the STAS is a particularly representative case study aiming at facilitating the link between science based analysis and stakeholder participation aiming at the adoption of sound transboundary management policies. Due to the scarcity of surface water, water-demanding activities in the study area rely only on groundwater. The first version of the model is developed adapting an existing model of the Namibian part of the aquifer: so far, the groundwater body is discretized using rectangular cells about 40 km2 wide and a stack of three aquifers divided respectively by three aquitards with variable thicknesses and heterogeneous hydraulic properties. The model setup is then revised integrating outcomes from the GGRETA project and extended until the groundwater body limits. Also, boundary conditions and hydrologic stresses (i.e., rainfall infiltration and abstraction for irrigation purposes) were re-defined according to maps and datasets available from the GGRETA project. The involvement of the UNESCO-IHP within the FREEWAT Consortium supports the coordination and integration of previous research outcomes (e.g., from the GGRETA project) and the model development to achieve a full characterization of the STAS current and forecast dynamics and possibly highlighting any existing knowledge gaps.

    A substantial challenge facing multicentre audit and research projects is timely recruitment of collaborators and their study centres. Cost-effective strategies are required and fee-free social media has previously been identified as a potential conduit. We investigated and evaluated the effectiveness of a novel multi-format social media and Internet strategy for targeted recruitment to a national multicentre cohort study. Interventions involved a new Twitter account, including weekly live question-and-answer sessions, a new Facebook group page, online YouTube presentations and an information page on a national association website. Link tracking analysis was undertaken using Google Analytics, which was then related to subsequent registration. Social influence was calculated using the proprietary Klout score. Internet traffic analysis identified a total of 1562 unique registration site views, of which 285 originated from social media (18.2%). Some 528 unique registrations were received, with 96 via social media platforms (18.2%). Traffic source analysis identified a separate national association webpage as resulting in the majority of registration page views (15.8%), followed by Facebook (11.9%), Twitter (4.8%) and YouTube (1.5%). A combination of publicity through Facebook, Twitter and the dedicated national association webpage contributed to the greatest rise in registration traffic and accounted for 312 (48%) of the total registrations within a 2-week period. A Twitter 'social influence' (Klout) score of 42/100 was obtained during this period. Targeted social media substantially aided study dissemination and collaborator recruitment. It acted as an adjunct to traditional methods, accounting for 18.2% of collaborator registration in a short time period with no associated financial costs. We provide a practical model for designing future recruitment campaigns, and recommend Facebook, Twitter and targeted websites as the most effective adjuncts for maximising cost

Social influence was calculated using the proprietary Klout score.Internet traffic analysis identified a total of 1562 unique registration site views, of which 285 originated from social media (18.2%. Some 528 unique registrations were received, with 96 via social media platforms (18.2%. Traffic source analysis identified a separate national association webpage as resulting in the majority of registration page views (15.8%, followed by Facebook (11.9%, Twitter (4.8% and YouTube (1.5%. A combination of publicity through Facebook, Twitter and the dedicated national association webpage contributed to the greatest rise in registration traffic and accounted for 312 (48% of the total registrations within a 2-week period. A Twitter 'social influence' (Klout score of 42/100 was obtained during this period.Targeted social media substantially aided study dissemination and collaborator recruitment. It acted as an adjunct to traditional methods, accounting for 18.2% of collaborator registration in a short time period with no associated financial costs. We provide a practical model for designing future recruitment campaigns, and recommend Facebook, Twitter and targeted websites as the most effective adjuncts for

    Full Text Available In this study we investigate the importance of agricultural sector research and technology organizations (RTO in the national economic system. The main objective of the paper is to identify and rank the factors affecting the promotion of these RTOs share in saffron’s added value. Through the literature review we extracted all the relevant factors that have been mentioned by different researchers. Then, we classified these factors into six components: applied research, technology acquisition, commercialization, market development, industry’s internal factors and national macro factors. We used a Likert scale questionnaire to gather the data about the importance of each factor based on research and technology experts’ points of view. To analyze the data we utilized confirmatory factor analysis and structural equation modeling (SEM methods using SPSS and smart PLS software packages. The results show that the most important factor affecting the share of agricultural RTOs in a products added value  is the promotion of industrial firms to invest in the field of agricultural research and development. Finally, according to the obtained results, some suggestions for improving research and technology have been provided.

    2013-06-01

    Full Text Available Background: General HIV-related orofacial lesions, most commonly oropharyngeal candidiasis, have a typical clinical appearance and can be recognised by members of the community. Although affected patients often experience pain leading to compromised eating and swallowing, barriers such as social stigma and lack of knowledge regarding available services may prevent them from seeking early care. Educating the community about these lesions through community health workers (CHWs who are democratically elected community members may encourage individuals affected to seek early oral health-care in the health facilities. A health facility (HF is a health centre mainly run by clinical officers (CO, i.e. personnel with a 3-year medical training, and nurses. This study aims to evaluate the effect of a CHW training programme on: i their knowledge and recognition of HIV-related oral-facial lesions at a community level; and ii referral of affected patients from the community to the HFs. Design and Methods: All 800 CHWs in 2 administrative divisions of Nairobi East District (test group n=400; control group n=400 will be selected. The test group will receive training. CHWs in both groups will be assessed at 4 time points: −3, 0, +3 and +6 months with reference to the training on: i their knowledge of HIV-related orofacial lesions (using a written questionnaire; and ii their performance in referring affected patients to the HFs (using clinical data. Expected Impact: Early recognition of HIV-related orofacial lesions at a community level will prompt community members to seek early oral care, leading to early HIV testing and counselling regarding failure of antiretroviral therapy, while treatment outcomes are still favourable.

    Failure-time data with cured patients are common in clinical studies. Data from these studies are typically analyzed with cure rate models. Variable selection methods have not been well developed for cure rate models. In this research, we propose two least absolute shrinkage and selection operators based methods, for variable selection in mixture and promotion time cure models with parametric or nonparametric baseline hazards. We conduct an extensive simulation study to assess the operating characteristics of the proposed methods. We illustrate the use of the methods using data from a study of childhood wheezing. © The Author(s) 2016.

  13. Alternans promotion in cardiac electrophysiology models by delay differential equations

    Gomes, Johnny M.; dos Santos, Rodrigo Weber; Cherry, Elizabeth M.

    2017-09-01

    Cardiac electrical alternans is a state of alternation between long and short action potentials and is frequently associated with harmful cardiac conditions. Different dynamic mechanisms can give rise to alternans; however, many cardiac models based on ordinary differential equations are not able to reproduce this phenomenon. A previous study showed that alternans can be induced by the introduction of delay differential equations (DDEs) in the formulations of the ion channel gating variables of a canine myocyte model. The present work demonstrates that this technique is not model-specific by successfully promoting alternans using DDEs for five cardiac electrophysiology models that describe different types of myocytes, with varying degrees of complexity. By analyzing results across the different models, we observe two potential requirements for alternans promotion via DDEs for ionic gates: (i) the gate must have a significant influence on the action potential duration and (ii) a delay must significantly impair the gate's recovery between consecutive action potentials.

    This study was conducted to test Pender's health promotion model in low-income, Korean elderly women. A total of 389 low-income, Korean elderly women completed the interviews focused on the concepts in health promotion model. Seventy-three percent of the variance in health-promoting behaviors was accounted for by prior health-related behavior, biological, psychological, and sociocultural factors, behavior-specific cognitions and affect, environmental influences, commitment to a plan of action, and health-promoting behavior variables in a modified health promotion model. Findings from this study may support the conceptual framework for future nursing practice and research studies in this vulnerable population.

    Epigenetic regulation in anxiety is suggested, but evidence from large studies is needed. We conducted an epigenome-wide association study (EWAS) on anxiety in a population-based cohort and validated our finding in a clinical cohort as well as a murine model. In the KORA cohort, participants (n=1522, age 32-72 years) were administered the Generalized Anxiety Disorder (GAD-7) instrument, whole blood DNA methylation was measured (Illumina 450K BeadChip), and circulating levels of hs-CRP and IL-18 were assessed in the association between anxiety and methylation. DNA methylation was measured using the same instrument in a study of patients with anxiety disorders recruited at the Max Planck Institute of Psychiatry (MPIP, 131 non-medicated cases and 169 controls). To expand our mechanistic understanding, these findings were reverse translated in a mouse model of acute social defeat stress. In the KORA study, participants were classified according to mild, moderate, or severe levels of anxiety (29.4%/6.0%/1.5%, respectively). Severe anxiety was associated with 48.5% increased methylation at a single CpG site (cg12701571) located in the promoter of the gene encoding Asb1 (β-coefficient=0.56 standard error (SE)=0.10, p (Bonferroni)=0.005), a protein hypothetically involved in regulation of cytokine signaling. An interaction between IL-18 and severe anxiety with methylation of this CpG cite showed a tendency towards significance in the total population (p=0.083) and a significant interaction among women (p=0.014). Methylation of the same CpG was positively associated with Panic and Agoraphobia scale (PAS) scores (β=0.005, SE=0.002, p=0.021, n=131) among cases in the MPIP study. In a murine model of acute social defeat stress, Asb1 gene expression was significantly upregulated in a tissue-specific manner (p=0.006), which correlated with upregulation of the neuroimmunomodulating cytokine interleukin 1 beta. Our findings suggest epigenetic regulation of the stress

    Adolescents have unique health considerations as they transition from parent-managed healthcare to personal responsibility for health behavior. One question to consider is the goodness-of-fit of available theoretical models for explaining and predicting adolescent health-promoting behavior. This integrative review explored Pender's health promotion model in relation to adolescent health. Specifically, this review summarizes the components of Pender's model and the supporting theoretical underpinnings based in the social cognitive theory. Research literature related to the health promotion model and various aspects of teen health is explored. Recommendations for further research and theory development are discussed.

    Promoting mental health is a central public health issue since the Jakarta statement in 1997. In Austria, the nationwide organisation for health promotion is the 'Fonds Gesundes Österreich' (FGÖ), which has been established in 1998. The FGÖ funds and supports workplace health promotion projects; therefore, it co-operates with the Austrian Network on Workplace Health Promotion. In 2011, among others, two Austrian companies were honoured as best practice models for promoting mental health in the project 'Work. In tune with life. Move Europe'. One of their central key success factors are the provision of equal opportunities, engagement, their focus on overall health as well as the implementation of behavioural and environmental preventive measures. Since mental health problems in the population are still rising, public health promotion projects which orientate on the best practice models have to be established in Austria.

    Three billion people use solid cooking fuels, and 4 million people die from household air pollution annually. Shifting households to clean fuels, like liquefied petroleum gas (LPG), may protect health only if stoves are consistently used. Few studies have used an implementation science framework to systematically assess "de-implementation" of traditional stoves, and none have done so with pregnant women who are more likely to adopt new behaviors. We evaluated an introduced LPG stove coupled with a phased behavioral intervention to encourage exclusive gas stove use among pregnant women in rural Guatemala. We enrolled 50 women at Theoretical Domains Framework (TDF). This included thematic analysis of focus group findings and classes delivered to 25 pregnant women (Phase 1). In Phase 2, we complemented classes with a home-based tailored behavioral intervention with a different group of 25 pregnant women. We mapped 35 TDF constructs onto survey questions. To evaluate stove use, we placed temperature sensors on wood and gas stoves and estimated fraction of stove use three times during pregnancy and twice during the first month after infant birth. Class attendance rates were above 92%. We discussed feasible ways to reduce HAP exposure, proper stove use, maintenance and safety. We addressed food preferences, ease of cooking and time savings through cooking demonstrations. In Phase 2, the COM-B framework revealed that other household members needed to be involved if the gas stove was to be consistently used. Social identity and empowerment were key in decisions about stove repairs and LPG tank refills. The seven intervention functions included training, education, persuasion, incentivization, modelling, enablement and environmental restructuring. Wood stove use dropped upon introduction of the gas stove from 6.4 h to 1.9 h. This is the first study using the COM-B Model to develop a behavioral intervention that promotes household-level sustained use of LPG stoves. This

    Advances in coronary artery surgery have reduced patient morbidity and mortality. Nevertheless, patients still have to face physical, psychological, and social problems after discharge from hospital. The objective of this study was to determine the efficacy of Pender's health promotion model in predicting cardiac surgery patients' lifestyles in Iran. This cross-sectional study comprised 220 patients who had undergone coronary artery bypass graft (CABG) surgery in Mazandaran province (Iran) in 2015. The subjects were selected using a simple random sampling method. The data were collected via (1) the health-promoting lifestyle profile II (HPLP II) and (2) a self-designed questionnaire that included two main sections: demographic characteristics and questions based on the health-promoting model constructs. Spiritual growth (28.77 ± 5.03) and physical activity (15.79 ± 5.08) had the highest and lowest scores in the HPLP II dimensions, respectively. All the health promotion model variables were significant predictors of health-promoting behaviors and explained 69% of the variance in health-promoting behaviors. Three significant predictors were estimated using regression coefficients: behavioral feelings (β = 0.390, P health-promoting model-based self-care behaviors can help identify and predict cardiac surgery patients' lifestyles in Iran. This pattern can be used as a framework for discharge planning and the implementation of educational interventions to improve the lifestyles of CABG patients.

    In elementary grades, comprehensive health education curricula mostly have demonstrated effectiveness in addressing singular health issues. The Michigan Model for Health (MMH) was implemented and evaluated to determine its impact on multiple health issues, including social and emotional skills, prosocial behavior, and drug use and aggression. Schools (N = 52) were randomly assigned to intervention and control conditions. Participants received 24 lessons in grade 4 (over 12 weeks) and 28 more lessons in grade 5 (over 14 weeks), including material focusing on social and emotional health, interpersonal communication, social pressure resistance skills, drug use prevention, and conflict resolution skills. The 40-minute lessons were taught by the classroom or health teacher who received curriculum training and provided feedback on implementation fidelity. Self-report survey data were collected from the fourth-grade students (n = 2512) prior to the intervention, immediately after the intervention, and 6 weeks after the intervention, with the same data collection schedule repeated in fifth grade. Students who received the curriculum had better interpersonal communication skills, social and emotional skills, and drug refusal skills than the control group students. Intervention students also reported lower intentions to use alcohol and tobacco, less alcohol and tobacco use initiated during the study and in the past 30 days, and reduced levels of aggression. The effectiveness of the MMH in promoting mental health and preventing drug use and aggression supports the call for integrated strategies that begin in elementary grades, target multiple risk behaviors, and result in practical and financial benefits to schools. © 2011, American School Health Association.

    2014-12-01

    We developed a method to model the cost-effectiveness at different levels of deprivation of an intervention to promote physical activity. The cost-effectiveness of a brief intervention in primary care was estimated by means of a Markov model stratified by deprivation quintile. Estimates for disease incidence, mortality, depression prevalence and health service utilization were obtained from 282 887 participants in the UK Clinical Practice Research Datalink with linked deprivation scores. Discounted results were compared for least deprived and most deprived quintiles. An effective intervention to promote physical activity continuing for 5 years gave an increase in life years free from disease: least deprived 54.9 (95% interval 17.5-93.5) per 1000 participants entering model; most deprived 74.5 (22.8-128.0) per 1000. The overall incremental quality adjusted life years were: least deprived, 3.7 per 1000 and most deprived, 6.1 per 1000 with probability cost-effective at £30 000 per QALY being 52.5 and 63.3%, respectively. When the intervention was modelled to be 30% less effective in the most deprived than the least deprived quintile, the probability cost-effective was least deprived 52.9% and most deprived 55.9%. Physical activity interventions may generate greater health benefits in deprived populations. When intervention effectiveness is attenuated in deprived groups, cost-effectiveness may sometimes still be similar to that in the most affluent groups. Even with favourable assumptions, evidence was insufficient to support wider use of presently available brief primary care interventions in a universal strategy for primary prevention. © The Author 2014, Published by Oxford University Press on behalf of Faculty of Public Health.

    1993-01-01

    A causal model based on Pender's (1987) Health Promotion Model was tested to evaluate Pender's hypothesis that demographic and biological characteristics affect health-promoting behaviors indirectly through three mediating cognitive-perceptual variables. A sample of 3,025 noninstitutionalized adults completed a telephone survey from which indicators of the conceptual variables were selected. Initial tests of the causal model using the LISREL 7 program indicated that the basic model did not fit the data. Therefore, the model was modified so that the exogenous variables--sex, age, income, martial status, education, and body mass index--had direct effects on select health-promoting behaviors. Further, the variables of self-actualization and interpersonal support were required to share common indicators as were health responsibility and interpersonal support. Though the modified model fit the data, little of the variance in health-promoting behaviors was explained, since all significant effects were weak.

    Full Text Available The aim of the present paper is to emphasize the role and importance of social media as a powerful wine promotion instrument. The necessity of approaching this issue is justified by the fact that we live in a Google-centric world and that companies’ marketing strategy as well as their content must constantly adapt to the online searching and information gathering behaviour. To this purpose, our research efforts concentrated on examining the top ten wine producers in Romania, pointing out that corporate rigor supports effective web-sites and social media accounts for wine producers. Form the marketing management perspective, the development of a model to assess the web-site and social media account is highly required as it is useful for winemaking companies. From the academic perspective, it aims at identifying the correlation between the behaviour of modern consumer and the social media impact on all aspects of life.

    2017-12-01

    Studies of childhood obesity have shown that fostering healthy life behaviors is more important than losing weight. However, studies reporting this result did not use a theoretical nursing model, which offers a systematic approach and scientific basis for studying the concepts and principles of nursing practice. The aim of this study was to determine the effects of an intervention that is based on Nola J. Pender's Health Promotion Model (HPM) on the healthy life behaviors and self-confidence of obese children. This quasi-experimental study enrolled 86 obese children and their parents (48 in the experimental group and 38 in the control group) as participants. The data collection tool was composed of an adaptation of a Pender's model-based evaluation form and the "Piers-Harris Self Confidence Scale." The experimental group received HPM-based individual and group education, whereas the control group received routine follow-up only. Whereas qualitative data were analyzed using content analysis, quantitative data were analyzed using a paired t test and Mann-Whitney U or Wilcoxon test. At the end of the education and follow-up program, experimental group participants showed a significant increase in healthy eating habits such as noting food portions (Z = 5.231, p Health professionals must recognize the physical, psychological, and social risks of obesity in children and focus on these problems to identify appropriate solutions. It is recommended that education and nursing follow-up programs be developed based on nursing models. This study found that patient education based on Pender's HPM increased healthy life behaviors (e.g., healthy nutrition and increased exercise time) and decreased sedentary activity substantially in the experimental group. This study further suggests that, although Pender's HPM has not been tested on obese children, this model offers effective guidelines for nursing activities that are targeted on developing healthy life behaviors in children.

    A male-female stacked version of Pender's Health Promotion Model (HPM) was used to evaluate whether the causal mechanisms underlying health promotion behaviors are the same for men and women. Indicators of the conceptual variables in the HPM were obtained from the National Survey of Personal Health Practices and Consequences, 1979-1980--a telephone sample survey of 3,025 noninstitutionalized adults. All coefficients to be estimated were initially constrained to be equal for men and women, except for six direct effects originating from marital status. The estimates obtained via the LISREL VI program indicated that the stacked model did not fit the data and that additional gender interactions were required between gender and other concepts within the HPM. Based on model diagnostics and with the relaxation of some equality constraints, a modified stacked model was constructed that fit the data. The explanatory power of the model was poor, calling into question the validity of the HPM. Theorists and researchers of health promotion should not assume that the causal mechanisms underlying health promotion behaviors in men and women are identical, but must forge ahead with an exploration and clarification of possible differences.

    BV in the centrifuge acceleration group had no significant difference compared those in control-CA group. Union rate and BV in the low-magnitude group of RFH model were also significantly higher than those in the other groups (Union rate: 60% v.s. 0% in the high-magnitude group and 10% in the control-VA group, BV: 0.69±0.30mm3 v.s. 0.15±0.09mm3 in high-magnitude group and 0.22±0.17mm3 in control-VA group. BV/TV in the low-magnitude group of RFH model was significantly higher than that in control-VA group (59.4±14.9% v.s. 35.8±13.5%. On the other hand, radiographic union rate (10% in centrifuge acceleration group v.s. 20% in control-CA group and micro-CT parameters in RFH model were not significantly different between two groups in the constant acceleration studies. Radiographic images of non-union rib fractures showed cartilage at the fracture site and poor new bone formation, whereas union samples showed only new bone. In conclusion, low-magnitude vibration acceleration promoted bone formation at the trunk in both BMP-induced ectopic bone formation and rib fracture healing models. However, the micro-CT parameters were not similar between two models, which suggested that there might be difference in the mechanism of effect by vibration between two models.

  16. Are we on the right track: can our understanding of abscission in model systems promote or derail making improvements in less studied crops?

    Sara E Patterson

    2016-01-01

    Full Text Available As the world population grows and resources and climate conditions change, crop improvement continues to be one of the most important challenges for agriculturalists. The yield and quality of many crops is affected by abscission or shattering, and environmental stresses often hasten or alter the abscission process. Understanding this process can not only lead to genetic improvement, but also changes in cultural practices and management that will contribute to higher yields, improved quality and greater sustainability. As plant scientists, we have learned significant amounts about this process through the study of model plants such as Arabidopsis, tomato, rice and maize. While these model systems have provided significant valuable information, we are sometimes challenged to use this knowledge effectively as variables including the economic value of the crop, the uniformity of the crop, ploidy levels, flowering and crossing mechanisms, ethylene responses, cultural requirements, responses to changes in environment, and cellular and tissue specific morphological differences can significantly influence outcomes. The value of genomic resources for lesser-studied crops such as cranberries and grapes and the orphan crop fonio will also be considered.

    Planning is an integral element of good management and necessary to anticipate events not merely respond to them. Projecting the quantity and spatial distribution of urban growth is essential to effectively plan for the delivery of city services and to evaluate potential environmental impacts. The major drivers of growth in large urban areas are increasing population, employment opportunities, and quality of life attractors such as a favorable climate and recreation opportunities. The spatial distribution of urban growth is dictated by the amount and location of developable land, topography, energy and water resources, transportation network, climate change, and the existing land use configuration. The Atlanta region is growing very rapidly both in population and the consumption of forestland or low-density residential development. Air pollution and water availability are significant ongoing environmental issues. The Prescott Spatial Growth Model (SGM) was used to make growth projections for the metropolitan Atlanta region to 2010,2020 and 2030 and results used for environmental assessment in both business as usual and smart growth scenarios. The Prescott SGM is a tool that uses an ESRI ArcView extension and can be applied at the parcel level or more coarse spatial scales and can accommodate a wide range of user inputs to develop any number of growth rules each of which can be weighted depending on growth assumptions. These projections were used in conjunction with meteorological and air quality models to evaluate future environmental impacts. This presentation will focus on the application of the SGM to the 13-County Atlanta Regional Commission planning jurisdiction as a case study. The SGM will be described, including how rule sets are developed and the decision process for allocation of future development to available land use categories. Data inputs required to effectively run the model will be discussed. Spatial growth projections for ten, twenty, and thirty

    Photodynamic therapy with aminolevulinic acid can be modified by pretreatment regimens with drugs such as 5- Fluorouracil (5-FU) or Vitamin D (calcitriol) that enhance accumulation of protoporphyrin IX (PpIX) within tumor tissue which presumably will enhance the therapeutic response to light. However, histological approaches for monitoring therapeutic responses are poorly suited for studying long term survival because large numbers of mice need to be sacrificed. To address this limitation, a non-invasive model to monitor tumor regression and regrowth has been established. Breast cancer cells, stably transfected with firefly luciferase (MDA-Luc cell line), are implanted orthotopically in nude mice (0.25 - 1 x 106 cells/site), and monitored 0-60 min after s.c. injection of luciferin, with Xenogen in-vivo imaging system. Luminescence is detectable at day 1 post-implantation. Tumors are suitable for experimentation on day 6, when daily injections of pretreatment agents (5-FU, 300 mg/kg; calcitriol, 1 μg/kg) begin. On day 9, ALA (75 mg/kg i.p.) is given for 4 hr, followed by illumination (633 nm, 100 J/cm2). Tumor luminescence post- PDT is monitored daily and compared with caliper measurements. Pretreatments (5-FU, calcitriol) by themselves do not inhibit luciferase expression, and all tumors grow at a similar rate during the pretreatment period. Results from in vivo survival experiments can be correlated to survival responses of MDA-Luc cells grown in monolayer cultures +/- PDT and +/- pretreatments, and additional mechanistic information (e.g. Ki67 and E-cadherin expression) obtained. In summary, this noninvasive model will permit testing of the therapeutic survival advantages of various pretreatments during cPDT.

    Identification of promoter region is an important part of gene annotation. Identification of promoters in eukaryotes is important as promoters modulate various metabolic functions and cellular stress responses. In this work, a novel approach utilizing intensity values of tilling microarray data for a model eukaryotic plant Arabidopsis thaliana, was used to specify promoter region from non-promoter region. A feed-forward back propagation neural network model supported by genetic algorithm was employed to predict the class of data with a window size of 41. A dataset comprising of 2992 data vectors representing both promoter and non-promoter regions, chosen randomly from probe intensity vectors for whole genome of Arabidopsis thaliana generated through tilling microarray technique was used. The classifier model shows prediction accuracy of 69.73% and 65.36% on training and validation sets, respectively. Further, a concept of distance based class membership was used to validate reliability of classifier, which showed promising results. The study shows the usability of micro-array probe intensities to predict the promoter regions in eukaryotic genomes.

  4. A Pervasive Promotion Model for Personalized Promotion Systems on Using WLAN Localization and NFC Techniques

    2015-01-01

    Full Text Available In this paper, we propose a novel pervasive business model for sales promotion in retail chain stores utilizing WLAN localization and near field communication (NFC technologies. The objectives of the model are to increase the customers’ flow of the stores and their incentives in purchasing. In the proposed model, the NFC technology is used as the first mean to motivate customers to come to the stores. Then, with the use of WLAN, the movements of the customers, who are carrying smartphones, within the stores are captured and maintained in the movement database. By interpreting the movements of customers as indicators of their interests to the displayed items, personalized promotion strategies can be formulated to increase their incentives for purchasing future items. Various issues in the application of the adopted localization scheme for locating customers in a store are discussed. To facilitate the item management and space utilization in displaying the items, we propose an enhanced R-tree for indexing the data items maintained in the movement database. Experimental results have demonstrated the effectiveness of the adopted localization scheme in supporting the proposed model.

    Mesenchymal stem cells (MSCs) are an attractive source for regenerative medicine because they are easily accessible through minimally invasive methods and have the potential to enhance liver regeneration (LG) and improve liver function, following partial hepatectomy (PH) and acute or chronic liver injury. A systematic review of the literature was conducted for articles published up to September 1st, 2016, using the MEDLINE database. The keywords that were used in various combinations were as follows: "Mesenchymal stem cells", "transplantation", "stem cells", "adipose tissue derived stem cells", "bone marrow-derived stem cells", "partial hepatectomy", "acute liver failure", "chronic liver failure", "liver fibrosis", "liver cirrhosis", "rats", "mice", and "liver regeneration". All introduced keywords were searched for separately in MeSH Database to control relevance and terminological accuracy and validity. A total of 41 articles were identified for potential inclusion and reviewed in detail. After a strict selection process, a total of 28 articles were excluded, leaving 13 articles to form the basis of this systematic review. MSCs transplantation promoted LG and improved liver function. Furthermore, MSCs had the ability to differentiate in hepatocyte-like cells, increase survival, and protect hepatocytes by paracrine mechanisms. MSCs transplantation may provide beneficial effects in the process of LG after PH and acute or chronic liver injury. They may represent a new therapeutic option to treat posthepatectomy acute liver failure.

    College students can establish healthy lifestyle practices that can have lifelong implications. Many students, however, continue to engage in risky behaviors such as active and passive smoking. The purpose of this study was to test an explanatory model of variables which can influence health promotion behaviors in smoking and nonsmoking college students. Pender's Health Promotion Model provided the framework for the study. Health promotion behaviors were found to be most effective when students: had an increased self-efficacy, avoided environmental tobacco smoke (ETS), perceived themselves as healthy, were female, and had a powerful external and internal health locus of control. College students may benefit from health promotion interventions designed to influence the avoidance of ETS and alter perceptions of self-efficacy, control of health, and health status. Such interventions may result in a decrease in both active and passive smoking.

    Survival data with a cured portion are commonly seen in clinical trials. Motivated from a biological interpretation of cancer metastasis, promotion time cure model is a popular alternative to the mixture cure rate model for analyzing such data. The existing promotion cure models all assume a restrictive parametric form of covariate effects, which can be incorrectly specified especially at the exploratory stage. In this paper, we propose a nonparametric approach to modeling the covariate effects under the framework of promotion time cure model. The covariate effect function is estimated by smoothing splines via the optimization of a penalized profile likelihood. Point-wise interval estimates are also derived from the Bayesian interpretation of the penalized profile likelihood. Asymptotic convergence rates are established for the proposed estimates. Simulations show excellent performance of the proposed nonparametric method, which is then applied to a melanoma study. Copyright © 2018 John Wiley & Sons, Ltd.

    The purposes of this study were to: (1) examine the relations among age, marital status, social class, perceived health, self-care agency, health-promoting lifestyle, and well-being in two groups of rural elderly Taiwanese women and (2) validate and compare two models using the two age groups of rural elderly Taiwanese women. Based on the conceptualizations of the major study variables in Orem's self-care model (1995), Pender's health promotion model (1987), and other scholars' ideas (Hartweg, 1990; Simmons, 1990), a theoretical model of health-promoting lifestyle was proposed for this study. A survey-interview method was used for data collection. Two groups of elderly women were recruited for data analysis: 168 in the younger group and 116 in the older group. The mean age was 64.66 in the younger group and 75.59 in the older group. Two models of health-promoting lifestyle were tested with a path analysis, using the Linear Structural Relations 8 (LISREL 8) program. The resultant models yielded chi2 of 13.69 with 9 degrees of freedom (p = 0.13) in the younger group and chi2 of 15.76 with 10 degrees of freedom (p = 0.11) in the older group. Other fit indices also indicate the two models fit the data well. Community nurses can assess, identify, and use effective interventions for rural elderly women on a basis of the resulting models.

    Introduction and Objectives. Nurses, as behavioral models, play a key role in health promotion, and their attitudes towards health promotion highly influence their health and performance. The aim of this study is to explore nursing students' perception of studies in nursing discipline as a situational influence on health promotion. Materials and Methods. This study was conducted using directed content analysis, by means of 20 deep semistructured interviews with nursing students. The participants were selected on purposive sampling. Data was analyzed by the qualitative content analysis method. All interviews were recorded, transcribed, and reviewed, and all codes were extracted and summarized. The codes were subcategorized on the basis of centralization and were categorized after review of subcategories, and finally, a theme was determined. Findings. The theme of nursing discipline's situational influence on nursing students' health promotion was revealed. This theme consisted of "choosing the field," "unfavorable environmental factors," "negative impacts of studies in nursing discipline on health," "positive effects of studies in nursing discipline on health", "needs," "attractiveness (aesthetics)," and "coping with negative situational influences in nursing discipline." Conclusion. The perception of studies in nursing discipline as a health-promoting behavior is under influence of social environment. Considering the importance of the students' positive perception of the existing situation, it is essential to pay attention to their attitudes and perceptions so that they can provide better services to patients.

    Background Advances in coronary artery surgery have reduced patient morbidity and mortality. Nevertheless, patients still have to face physical, psychological, and social problems after discharge from hospital. Objectives The objective of this study was to determine the efficacy of Pender’s health promotion model in predicting cardiac surgery patients’ lifestyles in Iran. Methods This cross-sectional study comprised 220 patients who had undergone coronary artery bypass graft (CABG) surgery in Mazandaran province (Iran) in 2015. The subjects were selected using a simple random sampling method. The data were collected via (1) the health-promoting lifestyle profile II (HPLP II) and (2) a self-designed questionnaire that included two main sections: demographic characteristics and questions based on the health-promoting model constructs. Results Spiritual growth (28.77 ± 5.03) and physical activity (15.79 ± 5.08) had the highest and lowest scores in the HPLP II dimensions, respectively. All the health promotion model variables were significant predictors of health-promoting behaviors and explained 69% of the variance in health-promoting behaviors. Three significant predictors were estimated using regression coefficients: behavioral feelings (β = 0.390, P health-promoting model-based self-care behaviors can help identify and predict cardiac surgery patients’ lifestyles in Iran. This pattern can be used as a framework for discharge planning and the implementation of educational interventions to improve the lifestyles of CABG patients. PMID:28144467

    This longitudinal study aimed to investigate the moderating effect of health-improving workplace environment on relationships between physical activity, self-efficacy, and psychological distress. Data were collected from 16 worksites and 129 employees at two time-points. Health-improving workplace environment was measured using the Japanese version of the Environmental Assessment Tool. Physical activity, self-efficacy, and psychological distress were also measured. Multi-level structural equation modeling was used to investigate the moderating effect of health-improving workplace environment on relationships between psychological distress, self-efficacy, and physical activity. Psychological distress was negatively associated with physical activity via low self-efficacy. Physical activity was negatively related to psychological distress. Physical activity/fitness facilities in the work environment exaggerated the positive relationship between self-efficacy and physical activity. Physical activity/fitness facilities in the workplace may promote employees' physical activity.

    Full Text Available MicroRNAs are short, noncoding RNAs that play important roles in post-transcriptional gene regulation. Although many functions of microRNAs in plants and animals have been revealed in recent years, the transcriptional mechanism of microRNA genes is not well-understood. To elucidate the transcriptional regulation of microRNA genes, we study and characterize, in a genome scale, the promoters of intergenic microRNA genes in Caenorhabditis elegans, Homo sapiens, Arabidopsis thaliana, and Oryza sativa. We show that most known microRNA genes in these four species have the same type of promoters as protein-coding genes have. To further characterize the promoters of microRNA genes, we developed a novel promoter prediction method, called common query voting (CoVote, which is more effective than available promoter prediction methods. Using this new method, we identify putative core promoters of most known microRNA genes in the four model species. Moreover, we characterize the promoters of microRNA genes in these four species. We discover many significant, characteristic sequence motifs in these core promoters, several of which match or resemble the known cis-acting elements for transcription initiation. Among these motifs, some are conserved across different species while some are specific to microRNA genes of individual species.

    Noncompliance with antiepileptic medication regimens is a leading cause of treatment failure. As a behavior, its causes are multifactorial and the degree to which it is exhibited varies from patient to patient. Interventions to encourage positive behavioral change need to be based on an understanding of the psychological, physiological and psychosocial aspects which explain noncompliance. Pender's Health Promotion Model provides a framework that can be used by the nurse to identify factors which interfere with the patient's ability to practice compliance and develop a treatment plan.

    Behavioral journalism influences audiences by presenting peer modeling for cognitive processes that lead to behavior change. This technique was used in student newsletters promoting intergroup tolerance and moral engagement in a Houston high school with a diverse ethnic composition. Pretest (N = 393) and posttest (N = 363) cross-sectional comparisons of the student population in that school provided evidence of short-term (6 month) communication effects on attitudes and behavior. Tolerance and moral engagement increased among students in the school where behavioral journalism newsletters were distributed, and there was a corresponding reduction in hostile behavioral intentions and in reports of verbal aggression.

    2011-06-01

    Full Text Available Management decision making methods frequently adopt quantitativemodels of several criteria that bypass the question of whysome criteria are considered more important than others, whichmakes more difficult the task of delivering a transparent viewof preference structure priorities that might promote ethics andlearning and serve as a basis for future decisions. To tackle thisparticular shortcoming of usual methods, an alternative qualitativemethodology of aggregating preferences based on the rankingof criteria is proposed. Such an approach delivers a simpleand transparent model for the solution of each preference conflictfaced during the management decision making process. Themethod proceeds by breaking the decision problem into ‘two criteria– two alternatives’ scenarios, and translating the problem ofchoice between alternatives to a problem of choice between criteriawhenever appropriate. The unicriterion model method is illustratedby its application in a car purchase and a house purchasedecision problem.

    To determine the types of attitudes to health promotion among older Austrians. Health promotion in old age becomes increasingly important in the current period of demographic transition. Interventions are likely to be successful if they take the attitude of older persons into consideration. There may be several types of attitudes to health promotion among older adults. Cross-sectional qualitative study. Semi-structured interviews were conducted in a purposive sample consisting of 36 home-dwelling older persons from local communities in the federal province of Salzburg, Austria. Data were analysed using qualitative content analysis according to Mayring and subsequent construction of types. There are three main types of attitudes to health promotion. 'Health promoters through everyday activities' considered domestic work and walks to be sufficient in keeping up their health. Fitness-oriented persons practised sports of some type. Users of complementary methods practised such methods to some degree. These types of attitudes could be further differentiated according to their outcome expectations. In addition to benefits for health, socialising was also an important outcome. Physical decline may reduce a fitness-oriented attitude, whereas encouragement by others may trigger it. Older adults have various attitudes to health promotion, but these are not immutable. Health promotion programmes that are not restricted to a narrow focus on health but provide the opportunity to socialise may support older adults in maintaining a healthy lifestyle. © 2016 John Wiley & Sons Ltd.

    In recent years the promotion of nuclear security culture aiming at strengthening nuclear security is extensively mentioned, however, awareness of nuclear security culture seems to be not much high compared to the permeation of nuclear safety culture. As a world's leading country of peaceful nuclear use, permeation of nuclear security culture into various social classes must be one of important issues in Japan. Learning from the TEPCO Fukushima Daiichi nuclear power plant accident, complementarity between nuclear safety and nuclear security in the aspect of both protection measures has been profoundly recognised. Therefore, it will be natural to promote nuclear security culture modelled on the preceding nuclear safety culture. On this standpoint, the paper examines an approach for the promotion of nuclear security culture which, for example, consists of awareness cultivation, attitude progress, permeation assessment, and resulting in the establishment of PDCA Cycle.

    The purpose of this study was to explain the health promotion behavior of Chinese international students in Korea using a structural equation model including acculturation factors. A survey using self-administered questionnaires was employed. Data were collected from 272 Chinese students who have resided in Korea for longer than 6 months. The data were analyzed using structural equation modeling. The p value of final model is .31. The fitness parameters of the final model such as goodness of fit index, adjusted goodness of fit index, normed fit index, non-normed fit index, and comparative fit index were more than .95. Root mean square of residual and root mean square error of approximation also met the criteria. Self-esteem, perceived health status, acculturative stress and acculturation level had direct effects on health promotion behavior of the participants and the model explained 30.0% of variance. The Chinese students in Korea with higher self-esteem, perceived health status, acculturation level, and lower acculturative stress reported higher health promotion behavior. The findings can be applied to develop health promotion strategies for this population. Copyright © 2016. Published by Elsevier B.V.

    The objective of this study was to describe the everyday physical activity habits of students and analyze the practice of physical activity and its determinants, based on the first component of Pender's health promotion model. This cross-sectional study was performed from 2004 to 2005 with 79 students in a public school in Fortaleza, Ceará, Brazil. Data collection was performed by interviews and physical examinations. The data were analyzed according to the referred theoretical model. Most students (n=60) were physically active. Proportionally, adolescents were the most active (80.4%). Those with a sedentary lifestyle had higher rates for overweight and obesity (21.1%). Many students practiced outdoor physical activities, which did not require any physical structure and good financial conditions. The results show that it is possible to associate the first component of Pender's health promotion model with the everyday lives of students in terms of the physical activity practice.

    The goal of this pilot study was to test the usefulness of Pender's (1987) theoretical model in predicting the adoption of health-promotion behaviours in 176 first-year undergraduate nursing students. Hierarchical regression analysis indicated that the perception of self-efficacy, perception of one's state of health, the influence of professors, and place of birth are predictive variables of health-promoting behaviours in this group. The results of this study suggest, among other things, that it is important for professors to use strategies that foster and support students' confidence in their ability to commit to health-promoting behaviours. A longitudinal study currently in progress will examine whether a health-oriented program significantly influences the adoption of health-promotion behaviours in nursing students during their university education.

    Objectives Intensified competitiveness in the healthcare industry has increased the number of healthcare centers and propelled the introduction of customer relationship management (CRM) systems to meet diverse customer demands. This study aimed to develop the information system success model of the CRM system by investigating previously proposed indicators within the model. Methods The evaluation areas of the CRM system includes three areas: the system characteristics area (system quality, information quality, and service quality), the user area (perceived usefulness and user satisfaction), and the performance area (personal performance and organizational performance). Detailed evaluation criteria of the three areas were developed, and its validity was verified by a survey administered to CRM system users in 13 nationwide health promotion centers. The survey data were analyzed by the structural equation modeling method, and the results confirmed that the model is feasible. Results Information quality and service quality showed a statistically significant relationship with perceived usefulness and user satisfaction. Consequently, the perceived usefulness and user satisfaction had significant influence on individual performance as well as an indirect influence on organizational performance. Conclusions This study extends the research area on information success from general information systems to CRM systems in health promotion centers applying a previous information success model. This lays a foundation for evaluating health promotion center systems and provides a useful guide for successful implementation of hospital CRM systems. PMID:23882416

    2012-01-01

    Full Text Available In this paper, the optimal planning of manpower training programmes in a manpower system with two grades is discussed. The planning of manpower training within a given organization involves a trade-off between training costs and expected return. These planning problems are examined through models that reflect the random nature of manpower movement in two grades. To be specific, the system consists of two grades, grade 1 and grade 2. Any number of persons in grade 2 can be sent for training and after the completion of training, they will stay in grade 2 and will be given promotion as and when vacancies arise in grade 1. Vacancies arise in grade 1 only by wastage. A person in grade 1 can leave the system with probability p. Vacancies are filled with persons in grade 2 who have completed the training. It is assumed that there is a perfect passing rate and that the sizes of both grades are fixed. Assuming that the planning horizon is finite and is T, the underlying stochastic process is identified as a finite state Markov chain and using dynamic programming, a policy is evolved to determine how many persons should be sent for training at any time k so as to minimize the total expected cost for the entire planning period T.

    Organizational health culture is a health-oriented core characteristic of the organization that is shared by all members. It is effective in regulating health-related behavior for employees and could therefore influence the effectiveness of health promotion efforts among organizations and employees. This study applied a multilevel analysis to verify the effects of organizational health culture on the organizational and individual effectiveness of health promotion. At the organizational level, we investigated the effect of organizational health culture on the organizational effectiveness of health promotion. At the individual level, we adopted a cross-level analysis to determine if organizational health culture affects employee effectiveness through the mediating effect of employee health behavior. The study setting consisted of the workplaces of various enterprises. We selected 54 enterprises in Taiwan and surveyed 20 full-time employees from each organization, for a total sample of 1011 employees. We developed the Organizational Health Culture Scale to measure employee perceptions and aggregated the individual data to formulate organization-level data. Organizational effectiveness of health promotion included four dimensions: planning effectiveness, production, outcome, and quality, which were measured by scale or objective indicators. The Health Promotion Lifestyle Scale was adopted for the measurement of health behavior. Employee effectiveness was measured subjectively in three dimensions: self-evaluated performance, altruism, and happiness. Following the calculation of descriptive statistics, hierarchical linear modeling (HLM) was used to test the multilevel hypotheses. Organizational health culture had a significant effect on the planning effectiveness (β = .356, p organizational health culture on three dimensions of employee effectiveness were completely mediated by health behavior. The construct connections established in this multilevel model will help in

    Full Text Available Iron deficiency anemia is one of the most common nutritional problems during pregnancy. The aim of this study was to evaluate the effect of education based on health belief model to promote preventive behaviors against iron deficiency anemia among pregnant women. The study was performed on 80 pregnant women that were randomized equally into the experimental and control groups. A self-administered questionnaire based on health belief model constructs was applied to gather data. The experimental group received two educational sessions. The mean age of women was 27.96±5.6 years and mean gestational age was 16.6±1 weeks. Before the intervention, no significant differences in terms of demographic characteristics and health belief model constructs were found between the groups, while after the intervention, the scores of health belief model were different significantly between the control and experimental groups . Since the results of the study indicated the applicability of health belief model to promote nutritional behavior in regard to anemia in pregnancy, implementing health belief model based educational sessions in health centers is suggested to reduce complications of this problem.

    National health initiatives emphasize the importance of eliminating health disparities among historically disadvantaged populations. Yet, few studies have examined the range of health outcomes among lesbian, gay, bisexual, and transgender (LGBT) people. To stimulate more inclusive research in the area, we present the Health Equity Promotion Model—a framework oriented toward LGBT people reaching their full mental and physical health potential that considers both positive and adverse health-related circumstances. The model highlights (a) heterogeneity and intersectionality within LGBT communities; (b) the influence of structural and environmental context; and (c) both health-promoting and adverse pathways that encompass behavioral, social, psychological, and biological processes. It also expands upon earlier conceptualizations of sexual minority health by integrating a life course development perspective within the health-promotion model. By explicating the important role of agency and resilience as well as the deleterious effect of social structures on health outcomes, it supports policy and social justice to advance health and well-being in these communities. Important directions for future research as well as implications for health-promotion interventions and policies are offered. PMID:25545433

    Despite consensus that exposure to media images of thin fashion models is associated with poor body image and disordered eating behaviours, few attempts have been made to enact change in the media. This study sought to investigate an effective alternative to current media imagery, by exploring the advertising effectiveness of average-size female fashion models, and their impact on the body image of both women and men. A sample of 171 women and 120 men were assigned to one of three advertisement conditions: no models, thin models and average-size models. Women and men rated average-size models as equally effective in advertisements as thin and no models. For women with average and high levels of internalisation of cultural beauty ideals, exposure to average-size female models was associated with a significantly more positive body image state in comparison to exposure to thin models and no models. For men reporting high levels of internalisation, exposure to average-size models was also associated with a more positive body image state in comparison to viewing thin models. These findings suggest that average-size female models can promote positive body image and appeal to consumers.

    International evidence reveals that hospital nurses have not been able to incorporate health promotion effectively into the framework of their care. This can be attributed to unclear conceptualizing of the barriers and facilitators to the role of nurses in health promotion. An integrative review was carried out to develop a conceptual model to assist hospital nurses in Jordan to understand how health promotion activities can be developed. Factors affecting the involvement of nurses in health promotion - ranging from limited knowledge about health promotion to the social image of nursing - can be structured into three levels: the micro (individual), meso (organizational) and macro (population). By understanding the interplay of factors between and within the levels, nurses and other health professionals can draw on the individual, social and organizational factors that influence nurses' role in health promotion. The proposed model can be considered as a springboard for developing health promotion activities related to hospitals in other Muslim-majority contexts.

    Higher occupational status has consistently been shown to be associated with better health, but few studies have to date examined if an upward change in occupational status is associated with a positive change in health. Furthermore, very little is known about whether this association differs by sex. Data were derived from four waves (2008-14) of the Swedish Longitudinal Occupational Survey of Health (SLOSH), a follow-up study of a nationally representative sample of the Swedish working population. The present study comprises 1410 men and 1926 women. A dynamic panel model with fixed effects was used to analyse the lagged association between job promotion on the one hand and self-rated health (SRH) and symptoms of depression on the other. This method allowed controlling for unobserved time-invariant confounders and determining the direction of causality between the variables. Multigroup comparisons were performed to investigate differences between the sexes. The results showed that job promotion was associated with decreased subsequent SRH and increased symptoms of depression among both men and women. Women reported a larger relative worsening of self-rated health following a job promotion than men and men reported a larger relative worsening of depression symptoms. There was limited evidence that SRH and symptoms of depression were associated with subsequent job promotion. The present study indicates that a job promotion could lead to decreased SRH and increased symptoms of depression in a 2-4-year perspective. Associations appear to differ for women and men. © The Author 2016; all rights reserved. Published by Oxford University Press on behalf of the International Epidemiological Association

    2013-03-01

    Humans with narcolepsy and orexin/ataxin-3 transgenic (TG) mice exhibit extensive, but incomplete, degeneration of hypo-cretin (Hcrt) neurons. Partial Hcrt cell loss also occurs in Parkinson disease and other neurologic conditions. Whether Hcrt antagonists such as almorexant (ALM) can exert an effect on the Hcrt that remains after Hcrt neurodegeneration has not yet been determined. The current study was designed to evaluate the hypnotic and cataplexy-inducing efficacy of a Hcrt antagonist in an animal model with low Hcrt tone and compare the ALM efficacy profile in the disease model to that produced in wild-type (WT) control animals. Counterbalanced crossover study. Home cage. Nine TG mice and 10 WT mice. ALM (30, 100, 300 mg/kg), vehicle and positive control injections, dark/active phase onset. During the 12-h dark period after dosing, ALM exacerbated cataplexy in TG mice and increased nonrapid eye movement sleep with heightened sleep/wake fragmentation in both genotypes. ALM showed greater hypnotic potency in WT mice than in TG mice. The 100 mg/kg dose conferred maximal promotion of cataplexy in TG mice and maximal promotion of REM sleep in WT mice. In TG mice, ALM (30 mg/ kg) paradoxically induced a transient increase in active wakefulness. Core body temperature (Tb) decreased after acute Hcrt receptor blockade, but the reduction in Tb that normally accompanies the wake-to-sleep transition was blunted in TG mice. These complex dose- and genotype-dependent interactions underscore the importance of effector mechanisms downstream from Hcrt receptors that regulate arousal state. Cataplexy promotion by ALM warrants cautious use of Hcrt antagonists in patient populations with Hcrt neurodegeneration, but may also facilitate the discovery of anticataplectic medications.

    Full Text Available Background and Objectives: Identifying the effective factors on oral health behaviors could have an important role in promotion of oral health in diabetic patients. Therefore, the aim of the present study was the assessment of cognitive-behavioral determinants of oral health in students using Pender's Health Promotion Model. Materials and Methods: In this cross-sectional study, 251 subjects were selected from Azad University, Payame Noor University and Sarab Faculty of Medical Sciences by multistage random sampling in 2016. To collect data, a standard instrument was applied based on Health Promotion Model (HPM structures. This questionnaire consisted of three parts: demographic variables, Pender’s HPM constructs items based on oral and dental health promotion, and health behavior. Results: The mean age (standard deviation was (21.9 ± 1.67. Oral health behaviors had statistically significant correlations with all of the HPM structures except for situational influences (r = 0.048. The HPM structures were able to predict 43.6% of oral heath behaviors and 24.6% of commitment to action. Self-efficacy (β = 0.342 was the strongest predictor to behavior and perceived barriers of commitment to action (β = -0.217. Conclusions: According to the results, self-efficacy was the strongest predictor of oral health behaviors and perceived barriers was the strongest predictors of commitment to action plan. Generally, based on the present study findings, HPM may be used as an appropriate framework for identifying factors and developing educational interventions, aiming at improving oral health behaviors among students.

    2015-02-01

    In heart failure (HF), T-tubule (TT) disruption contributes to dyssynchronous calcium (Ca) release and impaired contraction, but its role in arrhythmogenesis remains unclear. In this study, we investigate the effects of TT disruption and other HF remodeling factors on Ca alternans in ventricular myocytes using computer modeling. A ventricular myocyte model with detailed spatiotemporal Ca cycling modeled by a coupled Ca release unit (CRU) network was used, in which the L-type Ca channels and the ryanodine receptor (RyR) channels were simulated by random Markov transitions. TT disruption, which removes the L-type Ca channels from the associated CRUs, results in "orphaned" RyR clusters and thus provides increased opportunity for spark-induced Ca sparks to occur. This effect combined with other HF remodeling factors promoted alternans by two distinct mechanisms: 1) for normal sarco-endoplasmic reticulum Ca ATPase (SERCA) activity, alternans was caused by both CRU refractoriness and coupling. The increased opportunity for spark-induced sparks by TT disruption combined with the enhanced CRU coupling by Ca elevation in the presence or absence of increased RyR leakiness facilitated spark synchronization on alternate beats to promote Ca alternans; 2) for down-regulated SERCA, alternans was caused by the sarcoplasmic reticulum (SR) Ca load-dependent mechanism, independent of CRU refractoriness. TT disruption and increased RyR leakiness shifted and steepened the SR Ca release-load relationship, which combines with down-regulated SERCA to promote Ca alternans. In conclusion, the mechanisms of Ca alternans for normal and down-regulated SERCA are different, and TT disruption promotes Ca alternans by both mechanisms, which may contribute to alternans at different stages of HF.

    2015-01-01

    Background The foundation of best practice in health promotion is a robust theoretical base that informs design, implementation, and evaluation of interventions that promote the public’s health. This study provides a novel contribution to health promotion through the adaptation of the agenda-setting approach in response to the contribution of social media. This exploration and proposed adaptation is derived from a study that examined the effectiveness of Twitter in influencing agenda setting among users in relation to road traffic accidents in Saudi Arabia. Objective The proposed adaptations to the agenda-setting model to be explored reflect two levels of engagement: agenda setting within the social media sphere and the position of social media within classic agenda setting. This exploratory research aims to assess the veracity of the proposed adaptations on the basis of the hypotheses developed to test these two levels of engagement. Methods To validate the hypotheses, we collected and analyzed data from two primary sources: Twitter activities and Saudi national newspapers. Keyword mentions served as indicators of agenda promotion; for Twitter, interactions were used to measure the process of agenda setting within the platform. The Twitter final dataset comprised 59,046 tweets and 38,066 users who contributed by tweeting, replying, or retweeting. Variables were collected for each tweet and user. In addition, 518 keyword mentions were recorded from six popular Saudi national newspapers. Results The results showed significant ratification of the study hypotheses at both levels of engagement that framed the proposed adaptions. The results indicate that social media facilitates the contribution of individuals in influencing agendas (individual users accounted for 76.29%, 67.79%, and 96.16% of retweet impressions, total impressions, and amplification multipliers, respectively), a component missing from traditional constructions of agenda-setting models.

    2010-08-01

    Full Text Available Abstract Background Area deprivation is a known determinant of health. It is also known that area deprivation is associated with lower impact health promotion. It is less well known, however, whether deprived areas are less responsive to health promotion, or whether they are less exposed. Using data from a national, school-based campaign to promote vaccination against the human papilloma virus (HPV, the relationship between area deprivation and exposure was examined. Methods Taking advantage of a health promotion campaign to provide information to schools about HPV vaccination, a cross sectional study was conducted to examine the relationship between area level, social deprivation, and take-up of (i.e., exposure to available health promotion material. The sample was 4,750 schools across England, including government maintained and independent schools. The relationship between area deprivation and exposure was examined using bi- and multivariate logistic regression. Results It was found that schools in the least deprived quintile had 1.32 times the odds of requesting health promotion materials than schools in the most deprived areas (p = .01. This effect was independent of the school size, the type of school, and the geographic region. Conclusion The relationship between area deprivation and the impact of health promotion may be due, at least in part, to differential levels of exposure. The study was limited in scope, pointing to the need for more research, but also points to potentially important policy implications.

  16. Philanthropic Discourse vs Promotional Genre: To Study the Rhetorical Choices of Promotion and Structural Moves of Two Appeal Letters in Hong Kong

    2016-09-01

    Full Text Available Based on two appeal letters from (i Oxfam Hong Kong and (ii Hong Kong Committee For United Nations Children's Fund (UNICEF, this paper aims to study the rhetorical choices of promotion and structural moves of two appeal letters, exploring whether the philanthropic discourse can be viewed in line with the promotional genre. The findings appear to reveal that there is a hybrid form of promotional genre in philanthropic discourse, with reference to Bhatia’s (1998 generic patterns in fund-raising discourse framework. There are similar structural moves of advertising, although the move sequences could vary. However, the move of “introducing the cause” is always found at the very beginning because the readers are more interested to realise what the main theme of the appeal letter is. In addition, appeal letters are found to be modelled in promotional genre, in which they are rhetorical choices of promotion attracting attention from readers – by using “you” and marked devices of attention getters. The findings in this study appear to be in line with the argument that promotional concerns have influenced the nature of philanthropic discourse.

    The Youth Physical Activity Promotion (YPAP) model provides an integrated approach to understanding the predisposing, enabling, and reinforcing factors influencing physical activity (PA) behavior. The purpose of this study was to evaluate an adapted version of the YPAP model for explaining PA among Portuguese schoolchildren. A random cross-sectional sample of 683 children (8-10 years of age) attending elementary public schools in the north of Portugal completed a detailed survey assessing attraction to PA, perceived physical competence, parental influences and leisure time PA. Structural equation modeling techniques were conducted (EQS6.1). Attraction to PA was directly associated with children's PA participation (β = 0.271, P physical competence imposed an indirect effect on children's PA through children's attraction to PA (β = 0.253, P effect on children's PA through perceived physical competence and attraction to PA (β = 0.318 and 0.662, respectively, P physical competence and parental influence were not directly associated with children's PA (β = 0.069 and 0.180, respectively, P > .05). The adapted version of YPAP model was useful in explaining PA participation in elementary Portuguese schoolchildren. Intervention programs intended to enhance attraction to PA, perceived physical competence and favorable parental influence should be developed to promote children's PA participation.

    The rising number of international students studying outside their own country poses challenges for nursing education. Numbers are predicted to grow and economic factors are placing increasing pressure on tertiary institutions to accept these students. In adapting to a foreign learning environment international students must not only adapt to the academic culture but also to the socio-cultural context. The most significant acculturation issues for students are English as a second language, differences in education pedagogy and social integration and connectedness. Students studying in New Zealand need to work with Maori, the indigenous people, and assimilate and practice the unique aspects of cultural safety, which has evolved in nursing as part of the response to the principles underpinning the Treaty of Waitangi. The Hand Model offers the potential to support international students in a culturally safe manner across all aspects of acculturation including those aspects of cultural safety unique to New Zealand. The model was originally developed by Lou Jurlina, a nursing teacher, to assist her to teach cultural safety and support her students in practising cultural safety in nursing. The thumb, represents 'awareness', with the other four digits signifying 'connection" 'communication', 'negotiation' and 'advocacy' respectively. Each digit is connected to the palm where the ultimate evaluation of the Hand Model in promoting cultural safety culminates in the clasping and shaking of hands: the moment of shared meaning. It promotes a sense of self worth and identity in students and a safe environment in which they can learn.

    Hydrologic modeling is an essential component to understanding the physical processes that govern water resources systems. The process representation, approach, and scale used in each model can vary greatly among scientific domains. In addition, many models use proprietary data input and output file formats making it difficult to share results among scientists. These factors limit the extent to which cross disciplinary models can grow, and as a result, restricts collaboration across academic disciplines. The heterogeneity of data formats among models also inhibits archival due to the lack of consistent metadata and the inability to quickly inspect file contents. This work investigates a method for archiving model simulation input and output time series data in an easily accessible manner. We present a relational data model for representing simulation-based data that extends the functionality of the Observations Data Model (version 2). We demonstrate its use by implementing a PostgreSQL database with geospatial support via PostGIS, and illustrate how it is used to store and retrieve data to facilitate sharing among models and scientists.

    2012-02-01

    In order to explain phenomena at the quantum level, scientists use multiple representations in verbal, pictorial, mathematical, and computational forms. Conceptual coherence among these multiple representations is used as an analytical framework to describe student learning trajectories in quantum physics. A series of internet-based curriculum modules are designed to address topics in quantum mechanics, semiconductor physics, and nano-scale engineering applications. In these modules, students are engaged in inquiry-based activities situated in a highly interactive computational modeling environment. This study was conducted in an introductory level solid state physics course. Based on in-depth interviews with 13 students, methods for identifying conceptual coherence as a function of students' level of understanding are presented. Pre-post test comparisons of 20 students in the course indicate a statistically significant improvement in students' conceptual coherence of understanding quantum phenomena before and after the course, Effect Size = 1.29 SD. Additional analyses indicate that students who responded to the modules more coherently improved their conceptual coherence to a greater extent than those who did less to the modules after controlling for their course grades.

    To test the effects of integrating health protection and health promotion with a continuous improvement system (Kaizen) on proximal employee outcomes (health promotion, integration, and Kaizen) and distal outcomes (workability, productivity, self-rated health and self-rated sickness absence). Twelve units in a county hospital in Sweden were randomized to control or intervention groups using a quasiexperimental study design. All staff (approximately 500) provided self-ratings in questionnaires at baseline, and a 12- and 24-month follow-up (response rate, 79% to 87.5%). There was a significant increase in the proximal outcomes over time in the intervention group compared with the control group, and a trend toward improvement in the distal outcomes workability and productivity. Integration seems to promote staff engagement in health protection and promotion, as well as to improve their understanding of the link between work and health.

    Transcriptional regulation is the first level of regulation of gene expression and is therefore a major topic in computational biology. Genes with similar expression patterns can be assumed to be co-regulated at the transcriptional level by promoter sequences with a similar structure. Current approaches for modeling shared regulatory features tend to focus mainly on clustering of cis-regulatory sites. Here we introduce a Markov chain-based promoter structure model that uses both shared motifs and shared features from an input set of promoter sequences to predict candidate genes with similar expression. The model uses positional preference, order, and orientation of motifs. The trained model is used to score a genomic set of promoter sequences: high-scoring promoters are assumed to have a structure similar to the input sequences and are thus expected to drive similar expression patterns. We applied our model on two datasets in Caenorhabditis elegans and in Ciona intestinalis. Both computational and experimental verifications indicate that this model is capable of predicting candidate promoters driving similar expression patterns as the input-regulatory sequences. This model can be useful for finding promising candidate genes for wet-lab experiments and for increasing our understanding of transcriptional regulation.

    The aim was to investigate food sensory quality as experienced and perceived by patients at nutritional risk within the context of establishing a framework to develop foods to develop foods to promote intake. Patients at nutritional risk (NRS-2002; food intake ≤ 75% of requirements) were observed at meals in hospital (food choice, hunger/fullness/appetite scores). This was followed by a semi-structured interview based on the observations and focusing on food sensory perception and eating ability as related to food quality. Two weeks post-discharge, a 3-day food record was taken and interviews were repeated by phone. Interviews were transcribed, coded, and analysed thematically. Patients (N = 22) from departments of gastrointestinal surgery, oncology, infectious medicine, cardiology, and hepatology were interviewed at meals (N = 65) in hospital (82%) and post-discharge (18%). Food sensory perception and eating ability dictated specific food sensory needs (i.e., appearance, aroma, taste, texture, temperature, and variety defining food sensory quality to promote intake) within the context of motivation to eat including: pleasure, comfort, and survival. Patients exhibited large inter- and intra-individual variability in their food sensory needs. The study generated a model for optimising food sensory quality and developing user-driven, innovative foods to promote intake in patients at nutritional risk.

    Full Text Available Since, the nutritional behavior is a complicated process in which various factors play the role, this study aimed at specifying the effective factors in nutritional behavior of diabetic patients based on Health Promotion Model. This paper reviews the published articles from 2000 to the beginning of 2012, using the various data banks and search engines such as PubMed, ProQuest, Scopus, Elsevier, and the key words" perceived benefits and barriers, perceived self-efficacy, social support, activity related affect, situational influences, commitment to plan of action, immediate competing demands and diabetes, self-caring and diabetes. Unfavorable self-care situation especially, inappropriate nutritional behavior is related to some effective modifiable factors. Perceived benefits and self-efficacy regarding behaviors play a major role in the nutritional behaviors. Social support especially, spouses′ support has a significant role in this regard. Moreover, there is a reverse relationship between perceived barriers and nutritional self-care. In addition, behavioral feelings, situational influences, commitment to plan of action and immediate competing demands and preferences can also impact and overshadow the nutritional self-care. Following the relationship between constructs of Health Promotion Model and nutritional behavior the constructs of this model can be utilized as the basis for educational intervention among diabetes.

    2017-03-01

    Obesity remains a prominent societal threat and burden despite well-promoted prevention and treatment strategies, such as regular engagement in physical activity. Obese individuals, in particular, may be prone to inactivity as a result of a variety of displeasure-related parameters resulting from exercise, such as dyspnea, for instance. This brief conceptual review discusses the integral roles of exercise-induced affective responses within a novel conceptual-based neurocognitive affect-related model. Specifically, this model includes three pathways: (1) pathway A proposes that neurocognition, and especially, executive function-based cognition, may play an influential role in fostering exercise-induced affective responses, (2) pathway B connects an individual's affective response from exercise to their future exercise behavior, and (3) pathway C suggests a cyclical, bi-directional relationship with executive function indirectly influencing future exercise behavior via affective responses to exercise, and exercise itself playing an important role in executive functioning. Future studies should empirically test this model, which may have utility for promoting exercise among the obese population.

    2018-04-01

    This paper aims to present a modelling of bike sharing demand at station level in the city of Lyon. Multiple linear regression models were used in order to predict the daily flows of each station. The data used in this project consists of over 6 million bike sharing trips recorded in 2011. The built environment variables used in the model are determined in a buffer zone of 300 meters around each bike sharing station. The results show that bike sharing is principally used for commuting purposes. An interesting finding is that the bike sharing network characteristics are important parameters to improve the prediction quality of the models. The present results could be useful for others cities which want to adopt a bike sharing system and also for a better planning and operation of existing systems. The approach in this paper can be useful for estimating car-sharing demand.

    Successful demonstration of the effects of health promotion calls for systematic documentation and comparison of the outcome of different measures and projects. A model has been developed in the form of an outcome categorisation system for this purpose and is presented here. The model includes four categories covering the intermediate outcomes of health promotion measures, and three categories for outcomes at the level of health determinants (conditions necessary for health). Each category includes three to four sub-categories, for which examples of possible indicators are presented. The model can be applied both in the planning and in the evaluation stage of a project. This makes it possible for health promotion agencies and institutions responsible for funding and promotion to obtain a general overview of the outcome of their work.

    Social capital, as comprised of human connections in social networks and their associated benefits, is closely related to the health of individuals, communities, and societies at large. For disadvantaged population groups such as older adults and racial/ethnic minorities, social capital may play a particularly critical role in mitigating the negative effects and reinforcing the positive effects on health. In this project, we model social capital as both cause and effect by simulating dynamic networks. Informed in part by a community-based health promotion program, an agent-based model is contextualized in a GIS environment to explore the complexity of social disparities in oral and general health as experienced at the individual, interpersonal, and community scales. This study provides the foundation for future work investigating how health and healthcare accessibility may be influenced by social networks.

    The need for teamwork has grown significantly in today's organizations. Especially for online game communities, teamwork is an important means of online game players' engagement. This study aims to investigate the impacts of trust on players' teamwork with affective commitment and normative commitment as mediators. Furthermore, this research includes team experience as a moderator to compare the difference between different player groups. A model was proposed and tested on 296 online game players' data using structural equation modeling. Findings revealed that team experience moderated the relationship between trust and teamwork. The results indicated that trust promotes more teamwork only for players with high experience through affective commitment than those who with low experience. Implications of the findings are discussed.

    Full Text Available In this paper we established a mathematical model for national fitness in China. Based on a questionnaire and data of the General Administration of Sport of China and the National Bureau of Statistics of China, the dynamics for three classes of people are expressed by a system of three-dimensional ordinary equations. Model parameters are estimated from the data. This study indicated that national fitness put out by the Chinese government is reasonable. By finding the key parameter, the best measure to promote national fitness is put forward. In order to increase the number of people who frequently participate in sport exercise in a short period of time, if only one measure can be chosen, guiding people who never take part in physical exercise will be the best measure.

    In 1994 a pilot intergenerational project was started in the city of Taguatinga, Brazil, to promote the well-being of both elderly and adolescent populations using reminiscence processes as a means of interaction. The purpose of the study is to evaluate the project from the participants' viewpoint and to improve the contribution of those age groups in building up social capital. From November 1999 to April 2000 a qualitative study using focus groups technique was conducted. Using a discussion guide, 9 groups of students, ranging in age from 13 to 19 years old, and 3 groups of elderly aged 60 years and over were interviewed to collect data regarding their interaction before and after an intergenerational program. The main findings suggested a change in attitude of young people toward old age and elderly people. Participating elderly people reported improvement in their health status. For both age groups the findings suggested a better understanding between generations. It seems that reminiscence intergenerational activity contributes to building up mutual trust and reciprocity. These results seem to indicate this is an alternative for investing in social capital and improving participants' well-being. However, further work is needed to support these findings.

    2010-06-01

    Diabetes self-management is a challenge for both clients and health-care professionals. Empowerment plays a vital role in helping clients to achieve successful self-management. This study adopted a meta-ethnographic approach. Nine qualitative studies were synthesized in order to contribute to a deeper understanding of what clients perceive as being important in an effective empowerment strategy for diabetes self-management. Four central metaphors that influenced empowerment were identified: trust in nurses' competence and awareness, striving for control, a desire to share experiences, and nurses' attitudes and ability to personalize. The lines-of-argument synthesis suggested the need for an evaluation system to appraise clients' diabetes knowledge, health beliefs, and negative emotions, as well as the outcome of interventions. Based on Pender's Health Promotion Model, this study emphasizes the fact that health-care professionals need to understand and address modifiable behavior-specific variables. The study suggests that an effective empowerment strategy would be to use activity-related affect, as well as interpersonal and situational influences, as a means of facilitating and enhancing clients' health-promoting behaviors.

    Pharmacotherapeutic intervention during traumatic memory consolidation has been suggested to alleviate or even prevent the development of posttraumatic stress disorder (PTSD). We recently reported that, in a controlled, prospective animal model, depriving rats of sleep following stress exposure prevents the development of a PTSD-like phenotype. Here, we report that administering the wake-promoting drug modafinil to rats in the aftermath of a stressogenic experience has a similar prophylactic effect, as it significantly reduces the prevalence of PTSD-like phenotype. Moreover, we show that the therapeutic value of modafinil appears to stem from its ability to stimulate a specific circuit within the hypothalamus, which ties together the neuropeptide Y, the orexin system and the HPA axis, to promote adaptive stress responses. The study not only confirms the value of sleep prevention and identifies the mechanism of action of a potential prophylactic treatment after traumatic exposure, but also contributes to understanding mechanisms underlying the shift towards adaptive behavioral response.

    Promoter prediction is an integrant step for understanding gene regulation and annotating genomes. Traditional promoter analysis is mainly based on sequence compositional features. Recently, many kinds of structural features have been employed in promoter prediction. However, considering the high-dimensionality and overfitting problems, it is unfeasible to utilize all available features for promoter prediction. Thus it is necessary to choose some appropriate features for the prediction task. This paper conducts an extensive comparison study on feature selection of DNA structural properties for promoter prediction. Firstly, to examine whether promoters possess some special structures, we carry out a systematical comparison among the profiles of thirteen structural features on promoter and non-promoter sequences. Secondly, we investigate the correlations between these structural features and promoter sequences. Thirdly, both filter and wrapper methods are utilized to select appropriate feature subsets from thirteen different kinds of structural features for promoter prediction, and the predictive power of the selected feature subsets is evaluated. Finally, we compare the prediction performance of the feature subsets selected in this paper with nine existing promoter prediction approaches. Experimental results show that the structural features are differentially correlated to promoters. Specifically, DNA-bending stiffness, DNA denaturation and energy-related features are highly correlated with promoters. The predictive power for promoter sequences differentiates greatly among different structural features. Selecting the relevant features can significantly improve the accuracy of promoter prediction.

    Intraplaque angiogenesis associates with the instability of atherosclerotic plaques. In the present study, we investigated the effects of ghrelin on intraplaque angiogenesis and plaque instability in a rabbit model of atherosclerosis. The rabbits were randomly divided into three groups, namely, the control group, atherosclerotic model group, and ghrelin-treated group, with treatments lasting for 4 weeks. We found that the thickness ratio of the intima to media in rabbits of the ghrelin-treated group was significantly lower than that in rabbits of the atherosclerotic model group. The number of neovessels and the levels of vascular endothelial growth factor (VEGF) and vascular endothelial growth factor receptor 2 (VEGFR2) decreased dramatically in rabbits of the ghrelin-treated group compared to those of the atherosclerotic model group. Ghrelin significantly decreased the plaque content of macrophages, matrix metalloproteinase (MMP)-2, and MMP-9, in a rabbit model of atherosclerosis. In addition, the level of the pro-inflammatory factor monocyte chemoattractant protein (MCP)-1 was significantly lower in rabbits of the ghrelin-treated group than in rabbits of the atherosclerotic model group. In summary, ghrelin can inhibit intraplaque angiogenesis and promote plaque stability by down-regulating VEGF and VEGFR2 expression, inhibiting the plaque content of macrophages, and reducing MCP-1 expression at an advanced stage of atherosclerosis in rabbits.

    Despite the presence of increasing pressure towards globalisation, the coexistence of different cultures is a distinctive feature of human societies. However, how multiculturality can emerge in a population of individuals inclined to imitation, and how it remains stable under cultural drift, i.e. the spontaneous mutation of traits in the population, still needs to be understood. To solve such a problem, we propose here a microscopic model of culture dissemination which takes into account that, in real social systems, the interactions are organised in various layers corresponding to different interests or topics. We show that the addition of multiplexity in the modeling of our society generates qualitatively novel dynamical behavior, producing a new stable regime of cultural diversity. This finding suggests that the layered organisation of social influence typical of modern societies is the key ingredient to explain why and how multiculturality emerges and thrives in our world.

    2014-09-01

    Full Text Available Introduction: The present study as a systematic review investigated and analyzed interventions based on models and theories of health education and promotion in the field of physical activity in women. Materials and Methods: Three electronic databases, including Springer, Biomed Central and Science Direct were searched systematically. Only studies were selected that were quantitative, interventional and in English language as well as those that used at least one of the models and theories of health education and health promotion. Finally, 13 studies were reviewed that met the inclusion criteria and published from 2000 to 2013. Results: Of 13 studies reviewed, 10 studies measured levels of physical activity before and after the intervention, which nine interventions increased physical activity in the intervention group compared to the control group. Studies were conducted in different settings of health promotion including health care centers, community setting and workplace. The most widely used model was the Transtheoretical Model applied in eight of investigations. Conclusion: It is suggested to focus more on physical activity and duration of interventions to increase the efficacy of interventions. It is suggested to measure changes of physical activity habits in experimental and control groups in interventions based on the transtheoretical model to prepare a complementary scale to assess the efficacy of interventions. According to the results, no study had focused on changes in institutional policies or general health or providing changes in environment related to physical activity.

    Breast cancer is one of the most common cancers in women in the world. Although breast cancer is well treatable at the early stage, patients with distant metastases show a poor prognosis. Data from recent studies using transplantation models indicate that Mint3/APBA3 might promote breast cancer malignancy. However, whether Mint3 indeed contributes to tumor development, progression, or metastasis in vivo remains unclear. To address this, here we examined whether Mint3 depletion affects tumor malignancy in MMTV-PyMT breast cancer model mice. In MMTV-PyMT mice, Mint3 depletion did not affect tumor onset and tumor growth, but attenuated lung metastases. Experimental lung metastasis of breast cancer Met-1 cells derived from MMTV-PyMT mice also decreased in Mint3-depleted mice, indicating that host Mint3 expression affected lung metastasis of MMTV-PyMT-derived breast cancer cells. Further bone marrow transplant experiments revealed that Mint3 in bone marrow-derived cells promoted lung metastasis in MMTV-PyMT mice. Thus, targeting Mint3 in bone marrow-derived cells might be a good strategy for preventing metastasis and improving the prognosis of breast cancer patients. Copyright © 2017 Elsevier Inc.

    Candida albicans is a common opportunistic pathogen found in the oral mucosa. Clinical observations indicate a significant positive association between oral Candida carriage or infection and oral epithelial dysplasia/neoplasia. The aim of this study was to test whether C. albicans is able to promote epithelial dysplasia or carcinoma in a mouse model of infection where a carcinogen (4 Nitroquinoline 1-oxide [4NQO]) was used as initiator of neoplasia. Mice were divided into four groups: group 1 received 4NQO alone; group 2 received 4NQO followed by C. albicans (ATCC 90234); group 3 received vehicle dimethyl sulfoxide (DMSO) followed by C. albicans and group 4 was untreated. Although 4NQO treated mice did not develop oral lesions, mice exposed to both 4NQO and C. albicans developed oral dysplastic lesions 19 weeks after exposure to 4NQO. Mice challenged with C. albicans only developed hyperplastic lesions. The expression of Ki-67 and p16, two cell-cycle associated proteins that are frequently deregulated in oral dysplasia/neoplasia, was also tested in these lesions. Ki-67 and p16 expression increased from normal to hyperplastic to dysplastic mucosa and was highest in the group exposed to both 4NQO and C. albicans. In conclusion, we showed that C. albicans plays a role in the promotion of oral dysplasia in a mouse model of infection when 4NQO was used as initiator of oral neoplasia.

    Pender's health promotion model (HPM) has been revised, including substantial changes in its structure. The purpose of this study was to compare the fit and predictive usefulness of the original and revised structures of the HPM as applied to the use of hearing protection devices by 703 construction workers. Structural equation modeling was used to evaluate the two alternative forms of the model. Both forms of the model fit well, with the revised structure having a better fit and explaining more of the variance in use of hearing protection (28% vs. 18%). Results support the revised structure of the health promotion model (HPM) over the original form, and indicate it may be useful in understanding and predicting use of hearing protection.

    The core promoters play significant and extensive roles for the initiation and regulation of DNA transcription. The identification of core promoters is one of the most challenging problems yet. Due to the diverse nature of core promoters, the results obtained through existing computational approaches are not satisfactory. None of them considered the potential influence on performance of predictive approach resulted by the interference between neighboring TSSs in TSS clusters. In this paper, we sufficiently considered this main factor and proposed an approach to locate potential TSS clusters according to the correlation of regional profiles of DNA and TSS clusters. On this basis, we further presented a novel computational approach (ProMT) for promoter prediction using Markov chain model and predictive TSS clusters based on structural properties of DNA. Extensive experiments demonstrated that ProMT can significantly improve the predictive performance. Therefore, considering interference between neighboring TSSs is essential for a wider range of promoter prediction.

    Medical educators should promote the development of student clinical reasoning toward independence in clinical settings. The objective of this study was to evaluate an online problem-based learning (e-PBL) model designed to promote student individual reasoning in supplement to traditional PBL. Twelve e-PBL modules were added to the fully problem-based curriculum for Year 2 at Sungkyunkwan University School of Medicine (SKKUSOM). In this e-PBL, students worked on the problems individually in an online setting, followed by face-to-face discussions in a colloquium. The cases were presented using interactive multimedia to enhance the authenticity of the case and stimulate student interest in learning. A formative evaluation study was conducted to determine student satisfaction with e-PBL and its effectiveness as perceived by the students using both quantitative and qualitative methods. A cohort of Year 2 students at SKKUSOM (n = 38) took part in this study. Students perceived e-PBL significantly more positively after they had taken a module in terms of its ability to foster problem-solving skills and its ability to allow them to learn in ways suited to individual learning styles. Additionally, student survey and interview revealed that a vast majority of students were satisfied with the overall learning process in e-PBL and perceived it positively in fostering knowledge acquisition and clinical reasoning. Moreover, students found the cases realistic and engaging. The results show the potential of e-PBL to enhance traditional PBL by promoting the development of individual reasoning in a flexible online-learning environment and offering cases in an interactive multimedia format, which warrants further investigation into its impact on student learning outcomes.

    In profiling studies, the analysis of a single dataset often leads to unsatisfactory results because of the small sample size. Multi-dataset analysis utilizes information of multiple independent datasets and outperforms single-dataset analysis. Among the available multi-dataset analysis methods, integrative analysis methods aggregate and analyze raw data and outperform meta-analysis methods, which analyze multiple datasets separately and then pool summary statistics. In this study, we conduct integrative analysis and marker selection under the heterogeneity structure, which allows different datasets to have overlapping but not necessarily identical sets of markers. Under certain scenarios, it is reasonable to expect some similarity of identified marker sets - or equivalently, similarity of model sparsity structures - across multiple datasets. However, the existing methods do not have a mechanism to explicitly promote such similarity. To tackle this problem, we develop a sparse boosting method. This method uses a BIC/HDBIC criterion to select weak learners in boosting and encourages sparsity. A new penalty is introduced to promote the similarity of model sparsity structures across datasets. The proposed method has a intuitive formulation and is broadly applicable and computationally affordable. In numerical studies, we analyze right censored survival data under the accelerated failure time model. Simulation shows that the proposed method outperforms alternative boosting and penalization methods with more accurate marker identification. The analysis of three breast cancer prognosis datasets shows that the proposed method can identify marker sets with increased similarity across datasets and improved prediction performance.

    In South Africa, the expanding epidemic of non-communicable diseases is partly fuelled by high levels of physical inactivity and sedentary behaviour. Women especially are at high risk, and interventions promoting physical activity are urgently needed for girls in their adolescence, as this is the time when many girls adopt unhealthy lifestyles. This qualitative study aimed to identify and describe facilitating factors and barriers that are associated with physical activity among adolescent girls in rural, north-eastern South Africa and, based on these, to develop a model for promoting leisure-time physical activity within this population. The study was conducted in and around three secondary schools. Six focus group discussions were conducted with adolescent girls from the schools, and seven qualitative interviews were held with sports teachers and youth leaders. The data were subjected to thematic analysis. Seven thematic areas were identified, each of which was associated with the girls' self-reported levels of physical activity. The thematic areas are 1) poverty, 2) body image ideals, 3) gender, 4) parents and home life, 5) demographic factors, 6) perceived health effects of physical activity, and 7) human and infrastructural resources. More barriers to physical activity were reported than facilitating factors. Analysis of the barriers found in the different themes indicated potential remedial actions that could be taken, and these were synthesised into a model for promoting physical activity among South African adolescent girls in resource-poor environments. The model presents a series of action points, seen both from the 'supply-side' perspective (such as the provision of resources and training for the individuals, schools, and organisations which facilitate the activities) and from the 'demand-side' perspective (such as the development of empowering messages about body image for teenage girls, and encouraging more parental involvement).

    Full Text Available Abstract Background Screening for adolescent idiopathic scoliosis (AIS is a commonly performed procedure for school children during the high risk years. The PRECEDE-PROCEDE (PP model is a health promotion planning model that has not been utilized for the clinical diagnosis of AIS. The purpose of this research is to study AIS in the school age population using the PP model and its relevance for community, school, and clinical health promotion. Methods MEDLINE was utilized to locate AIS data. Studies were screened for relevance and applicability under the auspices of the PP model. Where data was unavailable, expert opinion was utilized based on consensus. Results The social assessment of quality of life is limited with few studies approaching the long-term effects of AIS. Epidemiologically, AIS is the most common form of scoliosis and leading orthopedic problem in children. Behavioral/environmental studies focus on discovering etiologic relationships yet this data is confounded because AIS is not a behavioral. Illness and parenting health behaviors can be appreciated. The educational diagnosis is confounded because AIS is an orthopedic disorder and not behavioral. The administration/policy diagnosis is hindered in that scoliosis screening programs are not considered cost-effective. Policies are determined in some schools because 26 states mandate school scoliosis screening. There exists potential error with the Adam's test. The most widely used measure in the PP model, the Health Belief Model, has not been utilized in any AIS research. Conclusion The PP model is a useful tool for a comprehensive study of a particular health concern. This research showed where gaps in AIS research exist suggesting that there may be problems to the implementation of school screening. Until research disparities are filled, implementation of AIS screening by school, community, and clinical health promotion will be compromised. Lack of data and perceived importance by

    Graduate education in gerontology has an essential role in providing the foundational knowledge required to work with a diverse aging population. It can also play an essential role in promoting best-practice approaches for the development of professional identity as a gerontologist. The primary goal of this study was to determine what factors predict the professional identity and career path of gerontologists. In addition, the study explored how experiential learning influenced professional identity for newcomers to the field and for those experienced in an aging-related field ("professional incumbents"). Graduates (N = 146) of Association for Gerontology in Higher Education-affiliated graduate programs participated. Professional identity as a gerontologist was predicted by length of time in the field, age, satisfaction with coworkers, and satisfaction with opportunities for advancement. Experiential learning contributed to professional identity in important but different ways for newcomers to the field and for professional incumbents. The inclusion of an academic/experiential learning model within graduate gerontology programs promotes the development of professional identity and career path for all graduate students.

    Studies show that African Americans are less likely than other ethnic groups to complete advance directives. However, what influences African Americans' decisions to complete or not complete advance directives is unclear. Using a faith-based promotion model, 102 African Americans aged 55 years or older were recruited from local churches and community-based agencies to participate in a pilot study to promote advance care planning. Focus groups were used to collect data on participants' preferences for care, desire to make personal choices, values and attitudes, beliefs about death and dying, and advance directives. A standardized interview was used in the focus groups, and the data were organized and analyzed using NUDIST 4 software (QRS Software, Victoria, Australia). Three fourths of the participants refused to complete advance directives. The following factors influenced the participants' decisions about end-of-life care and completion of an advance directive: spirituality; view of suffering, death, and dying; social support networks; barriers to utilization; and mistrust of the health care system. The dissemination of information apprises individuals of their right to self-determine about their care, but educational efforts may not produce a significant change in behavior toward completion of advance care planning. Thus, ongoing efforts are needed to improve the trust that African Americans have in medical and health care providers.

    Based on evidence from recent experiments in motor learning and neurorehabilitation, we hypothesize that three desirable features for a controller for robot-aided movement training following stroke are high mechanical compliance, the ability to assist patients in completing desired movements, and the ability to provide only the minimum assistance necessary. This paper presents a novel controller that successfully exhibits these characteristics. The controller uses a standard model-based, adaptive control approach in order to learn the patient's abilities and assist in completing movements while remaining compliant. Assistance-as-needed is achieved by adding a novel force reducing term to the adaptive control law, which decays the force output from the robot when errors in task execution are small. Several tests are presented using the upper extremity robotic therapy device named Pneu-WREX to evaluate the performance of the adaptive, "assist-as-needed" controller with people who have suffered a stroke. The results of these experiments illustrate the "slacking" behavior of human motor control: given the opportunity, the human patient will reduce his or her output, letting the robotic device do the work for it. The experiments also demonstrate how including the "assist-as-needed" modification in the controller increases participation from the motor system.

    2011-02-01

    Facing the lowest birth rates in its history, Taiwan is increasingly recognizing the centrality of children's healthcare needs to effective family care. The World Health Organization's goal of health for all emphasizes health promotion. However, little research attention has been given to how families actively promote personal health in everyday life. This article considers 'family-centric' healthcare, with a particular emphasis on children's health and well-being and the mother health promotion model. Authors employ a 'toy library' as the health promotion platform to build community interaction and empower the health enhancement process. Results suggested the following: 1. The fixed-point type toy library may be an effective tool in a health promotion strategy; 2. A model may be developed for rural institution agencies; 3. Cooperation may be facilitated using a medical service vehicle; 4. The love bag program can serve extended purposes. The authors found that the empowerment and growth of tribal mothers is a key element to facilitate the successful development of their children. Based on findings, the implementation of a toy library as the platform to build community-based health promotion model is suggested.

    This study was aimed to identify the major factors affecting performance in health promoting behaviors in women workers at small-scale industries. This study was based on the Pender's Health Promotion Model. The subjects for this study were 251 women workers at 23 small-scale industries in Busan city. The data for this study was collected from July 15th to August 15th 2003 by structured questionnaires, and were analyzed with ANOVA, t-test, Pearson' correlation coefficient, and multiple Regression in the SPSS/WIN 10.0. The mean performance of the health promoting behavior was 2.56. The factors related to the performance of the health promoting behaviors were social support, marital status, status of owning a house, perceived barriers to action, working time, and self-efficacy, and they explained 58.4% of the variance of the health promoting behaviors. The mean performance of the health promoting behavior seemed to be low, and the most important variable related to health promoting behaviors of women working at a small-scale industry was social support. Therefore, intervention programs to increase the social support for women worker need to be developed.

    To analyze the effects of an intervention based on the Transtheoretical Model on anthropometric and dietetic profile among women in the Primary Health Care in Brazil. Randomized controlled trial. The control group participated in physical activity and open group-education regarding nutrition of usual care. The intervention group participated in 10 workshops based on the Transtheoretical Model. Seventy-one women completed the study, with a mean age of 57.9±11.7years. Participants in the intervention group showed an improved body perception, reduced weight and body mass index post-intervention, and lower consumption of calories and foods high in fat. Significant weight reduction in the intervention group was associated with higher per capita income, reduced consumption of protein, reduced consumption of lipids, and the removal of visible fat from red meat and skin from chicken. An intervention based on the Transtheoretical Model promoted reduction in consumption of foods high in calories and fat, with positive effects on weight and body perception. These results provide evidence of the applicability and benefit of the Transtheoretical Model within primary care. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Background and aim Expenditure on adolescents' health promotion is critical to enhancing quality of life and fundamental for the prosperity of countries. This study tried to investigate the relationships between information-motivation-behavioral skills (IMB) model constructs as predictors of high school student's health-promoting lifestyle (HPL) in Southwest Iran. Methods This cross-sectional descriptive-analytic study was conducted on 400 students in Southwest Iran. Sample size required for this study was obtained using Soper's structural equation modeling (SEM) calculator. The stratified random sampling method was used in this study. A path analysis was taken to evaluate the HPL main determinants utilizing SEM. Results Information only had a significant indirect relationship with adolescents' HPL. But, both motivation and behavioral skills constructs had significant direct and indirect relationship with adolescents' HPL. The behavioral skill construct was the most imperative predictor variable. In general, behavioral skills construct (75%), motivation (66%) and knowledge (50%) constructs had the highest impact on HPL. The IMB model was able to explain 71% of the variance in adolescents' HPL. Conclusion The findings of the study showed that the IMB model was appropriate for explaining adolescents' HPL. It is necessary that actions are taken to improve behavioral skills and promote adolescents' HPL.

    Considering the population aging and the failure of biologistic and hospital-based treatment model, health promotion programs based on scientific evidence are necessary. A comprehensive review of literature was performed, aiming to identify and analyze health promotion and education experiments focused on the aging process. Papers published in eight databases, together with the database of the Pan-American Health Organization, were selected based on review of titles and abstracts, followed by a full text review conducted by two independent reviewers. A total of 22 studies were included, the majority of which adopted a quantitative approach, with a sample larger than 100 elderly or pre-retirement individuals. The majority of studies reported positive results in terms of health promotion and education. One study obtained minimum improvement and one reported that no statistically significant improvement had occurred. The positive effects most indicated by authors were: general or self-perceived improvement in physical health, improvement in psychosocial aspects and in relation to the aging process, improvement in adherence to preventative actions and in healthy conduct and lifestyle, increase in level of physical activity, improvement in quality of life and/or physical well-being, and improvement in activities of daily living or reduction of the risk of developing disabilities.

    The aim of this study was to investigate the sleep-promoting effect of combined γ-aminobutyric acid (GABA) and 5-hydroxytryptophan (5-HTP) on sleep quality and quantity in vertebrate models. Pentobarbital-induced sleep test and electroencephalogram (EEG) analysis were applied to investigate sleep latency, duration, total sleeping time and sleep quality of two amino acids and GABA/5-HTP mixture. In addition, real-time PCR and HPLC analysis were applied to analyze the signaling pathway. The GABA/5-HTP mixture significantly regulated the sleep latency, duration (pHTP mixture modulates both GABAergic and serotonergic signaling. Moreover, the sleep architecture can be controlled by the regulation of GABAA receptor and GABA content with 5-HTP. Copyright © 2016 Elsevier B.V. All rights reserved.

  20. A Multi-Scale Model of Hepcidin Promoter Regulation Reveals Factors Controlling Systemic Iron Homeostasis

    Science.gov (United States)

    Muckenthaler, Martina U.; Legewie, Stefan

    2014-01-01

    Systemic iron homeostasis involves a negative feedback circuit in which the expression level of the peptide hormone hepcidin depends on and controls the iron blood levels. Hepcidin expression is regulated by the BMP6/SMAD and IL6/STAT signaling cascades. Deregulation of either pathway causes iron-related diseases such as hemochromatosis or anemia of inflammation. We quantitatively analyzed how BMP6 and IL6 control hepcidin expression. Transcription factor (TF) phosphorylation and reporter gene expression were measured under co-stimulation conditions, and the promoter was perturbed by mutagenesis. Using mathematical modeling, we systematically analyzed potential mechanisms of cooperative and competitive promoter regulation by the transcription factors, and experimentally validated the model predictions. Our results reveal that hepcidin cross-regulation primarily occurs by combinatorial transcription factor binding to the promoter, whereas signaling crosstalk is insignificant. We find that the presence of two BMP-responsive elements enhances the steepness of the promoter response towards the iron-sensing BMP signaling axis, which promotes iron homeostasis in vivo. IL6 co-stimulation reduces the promoter sensitivity towards the BMP signal, because the SMAD and STAT transcription factors compete for recruiting RNA polymerase to the transcription start site. This may explain why inflammatory signals disturb iron homeostasis in anemia of inflammation. Taken together, our results reveal why the iron homeostasis circuit is sensitive to perturbations implicated in disease. PMID:24391488

    Reorienting work practices to include health promotion and prevention is complex and requires specific strategies and interventions. This paper presents original research that used 'real-world' practice to demonstrate that knowledge gathered from practice is relevant for the development of practice-based evidence. The paper shows how practitioners can inform and influence improvements in health promotion practice. Practitioner-informed evidence necessarily incorporates qualitative research to capture the richness of their reflective experiences. Using a participatory action research (PAR) approach, the research question asked 'what are the core dimensions of building health promotion capacity in a primary health care workforce in a real-world setting?' PAR is a method in which the researcher operates in full collaboration with members of the organisation being studied for the purposes of achieving some kind of change, in this case to increase the amount of health promotion and prevention practice within this community health setting. The PAR process involved six reflection and action cycles over two years. Data collection processes included: survey; in-depth interviews; a training intervention; observations of practice; workplace diaries; and two nominal groups. The listen/reflect/act process enabled lessons from practice to inform future capacity-building processes. This research strengthened and supported the development of health promotion to inform 'better health' practices through respectful change processes based on research, practitioner-informed evidence, and capacity-building strategies. A conceptual model for building health promotion capacity in the primary health care workforce was informed by the PAR processes and recognised the importance of the determinants approach. Practitioner-informed evidence is the missing link in the evidence debate and provides the links between evidence and its translation to practice. New models of health promotion service

    Purpose. The purpose of this article is to report a review and analysis of the concordance between current comprehensive corporate health promotion programs as described in the published literature and the systems model of health and to explore emerging trends in the field of health promotion. Search Methods. MEDLINE, BIOSIS, and PsycINFO searches were conducted from 1985 to 1991, and the bibliographies of articles thus obtained were back searched for additional descriptions of corporate health promotion programs. Inclusive criteria included "comprehensive" corporate programs, published in peer-reviewed journals or books, and descriptions adequate enough to permit coding in the majority of analysis matrix categories. Out of 63 identified programs, 16 met the inclusion criteria; 47 were excluded. A common reason for rejection was the limitation imposed by inadequate program descriptions in the published literature. Major Findings. On average, the comprehensive corporate programs reviewed were initiated between 1984 and 1987 and set in the context of a manufacturing firm with over 10,000 employees. A minority of programs (12.5%) consistently satisfied systems model criteria. The most common category of programs were those which were inconsistent (44%), meeting some of the criteria of a systems model of health promotion, but not all. The mechanistic medical and public health models predominated strongly (63%) with the preeminent goal being individual risk factor modification. Conclusions. The limitations of the published literature do not permit strong conclusions about the number or degree to which current corporate comprehensive programs are concordant with the systems model of health. Although mechanistic models of health predominated, there is evidence that a number of comprehensive programs were inconsistent with the mechanistic model, meeting some of the criteria, but also meeting some systems model criteria. To continue the advancement of health promotion with

    Full Text Available Shexiang Baoxin Pill (SBP originated from a classical TCM Fufang Suhexiang Pill for chest pain with dyspnea in the Southern Song Dynasty (1107–110 AD. Here, we aimed to evaluate preclinical evidence and possible mechanism of SBP for experimental coronary heart disease (CHD. Studies of SBP in animal models with CHD were identified from 6 databases until April 2016. Study quality for each included article was evaluated according to the CAMARADES 10-item checklist. Outcome measures were myocardial infarction area, vascular endothelial growth factor (VEGF and microvessel count (MVC. All the data were analyzed by using RevMan 5.1 software. As a consequence, 25 studies with 439 animals were identified. The quality score of studies ranged from 2 to 5, with the median of 3.6. Meta-analysis of seven studies showed more significant effects of SBP on the reduction of the myocardial infarction area than the control (P < 0.01. Meta-analysis of eight studies showed significant effects of SBP for increasing VEGF expression compared with the control (P < 0.01. Meta-analysis of 10 studies indicated that SBP significantly improved MVC compared with the control (P < 0.01. In conclusion, these findings preliminarily demonstrated that SBP can reduce myocardial infarction area, exerting cardioprotective function largely through promoting angiogenesis.

    Background and aim In social marketing, at the center of the program is consumer perception. The objective of this study was to explore the viewpoints of Iranian women for tailoring interventions so as to increase physical activity. Methods The social marketing model served as the framework of the study. Qualitative data were collected via six semi-structured focus group discussions (FGDs), in 2014 in Iran. Participants were 51 women, 20 to 60 years old, selected by purposive sampling, with a maximum diversity. Qualitative content analysis of the data was conducted by researchers. Results After data analysis and extracting initial codes, they were all categorized in four predefined categories of social marketing model (product, price, place and promotion) and related sub-categories. Most of the participants were inactive. Price was addressed by women as the dominant category of this study. The majority of participants emphasized the benefits of prevention of chronic diseases, fitness, staying young, and improving family relations. Most women preferred to do physical activity in a secure and enclosed female environment. And the majority of participants considered radio, television, face to face training, texting, and advertising billboards as promotional strategies. Conclusion This study provides a unique insight into consumers’ values and motivations that affect consumers’ decisions to adopt physical activity, in Iran. It could also help researchers to design and implement intervention programs to increase physical activity. PMID:29038710

    Pedro Beschoren da Costa

    Full Text Available Plant growth-promoting bacteria can greatly assist sustainable farming by improving plant health and biomass while reducing fertilizer use. The plant-microorganism-environment interaction is an open and complex system, and despite the active research in the area, patterns in root ecology are elusive. Here, we simultaneously analyzed the plant growth-promoting bacteria datasets from seven independent studies that shared a methodology for bioprospection and phenotype screening. The soil richness of the isolate's origin was classified by a Principal Component Analysis. A Categorical Principal Component Analysis was used to classify the soil richness according to isolate's indolic compound production, siderophores production and phosphate solubilization abilities, and bacterial genera composition. Multiple patterns and relationships were found and verified with nonparametric hypothesis testing. Including niche colonization in the analysis, we proposed a model to explain the expression of bacterial plant growth-promoting traits according to the soil nutritional status. Our model shows that plants favor interaction with growth hormone producers under rich nutrient conditions but favor nutrient solubilizers under poor conditions. We also performed several comparisons among the different genera, highlighting interesting ecological interactions and limitations. Our model could be used to direct plant growth-promoting bacteria bioprospection and metagenomic sampling.

    Background Analysis of nursing theoretical works and its role in knowledge development is presented as an essential process of critical reflection. Health promotion model (HPM) focuses on helping people achieve higher levels of well-being and identifies background factors that influence health behaviors. Objectives This paper aims to evaluate, and critique HPM by Barnum's criteria. Methods The present study reviewed books and articles derived from Proquest, PubMed, Blackwell Databases. The method of evaluation for this model is based on Barnum's criteria for analysis, application and evaluation of nursing theories. The criteria selected by Barnum embrace both internal and external criticism. Internal criticism deals with how theory components fit with each other (internal construction of theory) and external criticism deals with the way in which theory relates to the extended world (which considers theory in its relationships to human beings, nursing, and health). Results The electronic database search yielded over 27,717 titles and abstracts. Following removal of duplicates, 18,963 titles and abstracts were screened using the inclusion criteria and 1278 manuscripts were retrieved. Of these, 80 were specific to HPM and 23 to analysis of any theory in nursing relating to the aim of this article. After final selection using the inclusion criteria for this review, 28 manuscripts were identified as examining the factors contributing to theory analysis. Evaluation of health promotion theory showed that the philosophical claims and their content are consistent and clear. HPM has a logical structure and was applied to diverse age groups from differing cultures with varying health concerns. Conclusion In conclusion, among the strategies for theory critique, the Barnum approach is structured and accurate, considers theory in its relationship to human beings, community psychiatric nursing, and health. While according to Pender, nursing assessment, diagnosis and interventions

    2017-06-01

    Full Text Available Sports participation can confer a range of physical and psychosocial benefits and, for refugee and migrant youth, may even act as a critical mediator for achieving positive settlement and engaging meaningfully in Australian society. This group has low participation rates however, with identified barriers including costs; discrimination and a lack of cultural sensitivity in sporting environments; lack of knowledge of mainstream sports services on the part of refugee-background settlers; inadequate access to transport; culturally determined gender norms; and family attitudes. Organisations in various sectors have devised programs and strategies for addressing these participation barriers. In many cases however, these responses appear to be ad hoc and under-theorised. This article reports findings from a qualitative exploratory study conducted in a range of settings to examine the benefits, challenges and shortcomings associated with different participation models. Interview participants were drawn from non-government organisations, local governments, schools, and sports clubs. Three distinct models of participation were identified, including short term programs for refugee-background children; ongoing programs for refugee-background children and youth; and integration into mainstream clubs. These models are discussed in terms of their relative challenges and benefits and their capacity to promote sustainable engagement and social inclusion for this population group.

    The inference of regulatory interactions and quantitative models of gene regulation from time-series transcriptomics data has been extensively studied and applied to a range of problems in drug discovery, cancer research, and biotechnology. The application of existing methods is commonly based on implicit assumptions on the biological processes under study. First, the measurements of mRNA abundance obtained in transcriptomics experiments are taken to be representative of protein concentrations. Second, the observed changes in gene expression are assumed to be solely due to transcription factors and other specific regulators, while changes in the activity of the gene expression machinery and other global physiological effects are neglected. While convenient in practice, these assumptions are often not valid and bias the reverse engineering process. Here we systematically investigate, using a combination of models and experiments, the importance of this bias and possible corrections. We measure in real time and in vivo the activity of genes involved in the FliA-FlgM module of the E. coli motility network. From these data, we estimate protein concentrations and global physiological effects by means of kinetic models of gene expression. Our results indicate that correcting for the bias of commonly-made assumptions improves the quality of the models inferred from the data. Moreover, we show by simulation that these improvements are expected to be even stronger for systems in which protein concentrations have longer half-lives and the activity of the gene expression machinery varies more strongly across conditions than in the FliA-FlgM module. The approach proposed in this study is broadly applicable when using time-series transcriptome data to learn about the structure and dynamics of regulatory networks. In the case of the FliA-FlgM module, our results demonstrate the importance of global physiological effects and the active regulation of FliA and FlgM half-lives for

    Full Text Available Abstract Background Most women delivering in South African State Maternity Hospitals do not have a childbirth companion; in addition, the quality of care could be better, and at times women are treated inhumanely. We piloted a multi-faceted intervention to encourage uptake of childbirth companions in state hospitals, and hypothesised that lay carers would improve the behaviour of health professionals. Methods We conducted a pilot randomised controlled trial of an intervention to promote childbirth companions in hospital deliveries. We promoted evidence-based information for maternity staff at 10 hospitals through access to the World Health Organization Reproductive Health Library (RHL, computer hardware and training to all ten hospitals. We surveyed 200 women at each site, measuring companionship, and indicators of good obstetric practice and humanity of care. Five hospitals were then randomly allocated to receive an educational intervention to promote childbirth companions, and we surveyed all hospitals again at eight months through a repeat survey of postnatal women. Changes in median values between intervention and control hospitals were examined. Results At baseline, the majority of hospitals did not allow a companion, or access to food or fluids. A third of women were given an episiotomy. Some women were shouted at (17.7%, N = 2085, and a few reported being slapped or struck (4.3%, N = 2080. Despite an initial positive response from staff to the childbirth companion intervention, we detected no difference between intervention and control hospitals in relation to whether a companion was allowed by nursing staff, good obstetric practice or humanity of care. Conclusion The quality and humanity of care in these state hospitals needs to improve. Introducing childbirth companions was more difficult than we anticipated, particularly in under-resourced health care systems with frequent staff changes. We were unable to determine whether the presence

    The Taiwanese Network of Health Promoting Hospitals (HPH) has been in place since 2006 and developing rapidly. The criticism of inadequate evaluation of the HPH approach taken elsewhere also holds true for the Taiwan HPH Network. Organizational change is a key to sustainable and effective health promotion, and it is also an important aspect in the European HPH movement. Therefore, this study aims to evaluate changes in organizational capacity for the implementation of HPH in Taiwan. All 55 HPH coordinators were invited to participate in the study, and 52 of them completed the questionnaires. The survey covered seven dimensions of HPH organizational capacity, and a total score of each dimension was calculated and converted to a figure on a scale of 10. This study has shown that HPH made a positive impact on HP hospitals in Taiwan regarding organizational change in capacity building for HPH. Leadership, organization culture and mission and strategy received the top three highest mean scores (8.19 ± 1.25, 8.08 ± 1.39, 7.99 ± 1.42), while staff participation received the lowest score (7.62 ± 1.26). The high level of organizational change was associated with the high satisfaction levels of organizational support from the viewpoint of the HPH coordinators. Based on a cluster analysis, a majority of the HP hospitals in Taiwan seemed to have adopted the addition model in putting the HPH initiative into practice; a few hospitals appeared to have accepted HPH initiative well through the integration model. These results presented evidence that HPH contributed to organizational capacity building of hospitals for health promotion.

    To investigate the effect of oligochitosan in promoting intestinal absorption of protoberberine alkaloids in extracts from Corydalis saxicola total alkaloids. The in vitro single-pass intestinal perfusion model in rats was established to study the changes in absorption kinetic parameters of dehydrocavidine, berberine hydrochloride and palmatine chloride in C. saxicola total alkaloids after the addition of different concentrations oligochitosan and evaluate the effect of oligochitosan in promoting intestinal absorption of the drugs. The concentration of oligochitosan had different effects on the absorption rate constant (Ka) and apparent permeability coefficient (Peff) of the three active component in rat intestines. Ka and Peff in 0.5% oligochitosan group significantly increased, indicating a stronger effect in promoting the absorption. Oligochitosan has a certain effect in promoting the intestinal absorptions of protoberberine alkaloids in C. saxicola total alkaloids.

    Full Text Available Abstract Background Prior literature has shown that physicians with healthy personal habits are more likely to encourage patients to adopt similar habits. However, despite the possibility that promoting medical student health might therefore efficiently improve patient outcomes, no one has studied whether such promotion happens in medical school. We therefore wished to describe both typical and outstanding personal health promotion environments experienced by students in U.S. medical schools. Methods We collected information through four different modalities: a literature review, written surveys of medical school deans and students, student and dean focus groups, and site visits at and interviews with medical schools with reportedly outstanding student health promotion programs. Results We found strong correlations between deans' and students' perceptions of their schools' health promotion environments, including consistent support of the idea of schools' encouraging healthy student behaviors, with less consistent follow-through by schools on this concept. Though students seemed to have thought little about the relationships between their own personal and clinical health promotion practices, deans felt strongly that faculty members should model healthy behaviors. Conclusions Deans' support of the relationship between physicians' personal and clinical health practices, and concern about their institutions' acting on this relationship augurs well for the role of student health promotion in the future of medical education. Deans seem to understand their students' health environment, and believe it could and should be improved; if this is acted on, it could create important positive changes in medical education and in disease prevention.

    Full Text Available This study was undertaken in order to develop a model of facilitation of emotional intelligence to promote wholeness in neophyte critical care nurses in South Africa. A theory generative, explorative, descriptive, contextual research design was used. The model was developed utilising the four steps of theory generation as proposed by Dickoff, James, and Wiedenbach (1968, Chinn and Kramer (2011 and Walker and Avant (2011. Step one dealt with the empirical phase in which the concepts were distilled. The facilitation of inherent affective and mental resourcefulness and resilience was the main concept of the model. Step two comprised the definition and classification of central and related concepts. Step three provides a description of the model. The model operates in three phases namely the dependent phase, partially dependent phase and the independent phase. Step four entailed the description of guidelines for operationalizing the model. During the three phases of the model a new nurse who starts to work in critical care moves from a latent ability to develop an inherent affective and mental resourcefulness and resilience to a state of developing an inherent affective and mental resourcefulness and resilience. This model provides a structured framework for the facilitation of emotional intelligence (EI to promote wholeness in nurses who commence to work in critical care units.

    China launched low-carbon city strategy to respond global climate change. Industrial symbiosis (IS) could generate both economic and environmental benefits in clustered industries and communities. This research shed light on how industrial symbiosis contributes to city's low-carbon development. An urban-level hybrid physical input and monetary output (HPIMO) model which covers physical energy inputs and air pollutants emissions, is established for addressing case study in a Chinese typical industrial city (Liuzhou). Based on current energy consumption and industrial symbiosis and the application of HPIMO model, scenarios related to industrial symbiosis, including waste plastics recycling, scrap tires recycling, flying ash recycling and biomass utilization are explored. Results show that compared with business-as-usual (BAU) scenario, IS can reduce solid wastes and further contribute to the co-benefits of energy saving, CO 2 emissions reduction and air pollutants reduction. The finding is critical for national low-carbon strategy. Finally, policy implications to support the ever-improvement of IS promotion in China are proposed and discussed. - Highlights: • Industrial symbiosis could contribute to low-carbon city in terms of co-benefit. • Co-benefit of IS was in terms of waste reduction and air pollutants reduction. • Waste plastics recycling and biomass utilization generated large co-benefit. • Coal fly ash recycling reduced the solid waste while increased air pollutants. • The prices of wastes and facilities investment affected the total cost-benefit

    This aim of this study was to increase dairy consumption in students following an education intervention based on Pender's Health Promotion Model (Pender's HPM) variables. The study was done during September 2014-April 2015 in Savojbolagh, Alborz, Iran. The study sample included 142 middle-school female students who were allocated to either the intervention (n=71) or the comparison group (n=71). Pender's HPM variables and the daily servings of dairy foods consumed were measured in both groups by a self-administered questionnaire and a 3 d record before the intervention and 4 weeks later. The 4-week intervention was conducted for the intervention group. The data was analyzed through analysis of covariance and paired t tests. Compared to the comparison group, there were significant differences in Pender's HPM variables (except for the negative feelings, perceived barriers and competing demands), the daily servings of dairy foods consumed, and intakes of Calcium, riboflavin, and vitamin A in the intervention participants following the conducted intervention program. Developing theory-driven nutrition education programs may increase student's dairy foods intake.

    Full Text Available Nicotine is the major addictive component of tobacco smoke. Although nicotine is generally thought to have limited ability to initiate cancer, it can induce cell proliferation and angiogenesis in a variety of systems. These properties might enable nicotine to facilitate the growth of tumors already initiated. Here we show that nicotine significantly promotes the progression and metastasis of tumors in mouse models of lung cancer. This effect was observed when nicotine was administered through intraperitoneal injections, or through over-the-counter transdermal patches.In the present study, Line1 mouse adenocarcinoma cells were implanted subcutaneously into syngenic BALB/c mice. Nicotine administration either by intraperitoneal (i.p. injection or transdermal patches caused a remarkable increase in the size of implanted Line1 tumors. Once the tumors were surgically removed, nicotine treated mice had a markedly higher tumor recurrence (59.7% as compared to the vehicle treated mice (19.5%. Nicotine also increased metastasis of dorsally implanted Line1 tumors to the lungs by 9 folds. These studies on transplanted tumors were extended to a mouse model where the tumors were induced by the tobacco carcinogen, NNK. Lung tumors were initiated in A/J mice by i.p. injection of NNK; administration of 1 mg/kg nicotine three times a week led to an increase in the size and the number of tumors formed in the lungs. In addition, nicotine significantly reduced the expression of epithelial markers, E-Cadherin and beta-Catenin as well as the tight junction protein ZO-1; these tumors also showed an increased expression of the alpha(7 nAChR subunit. We believe that exposure to nicotine either by tobacco smoke or nicotine supplements might facilitate increased tumor growth and metastasis.Our earlier results indicated that nicotine could induce invasion and epithelial-mesenchymal transition (EMT in cultured lung, breast and pancreatic cancer cells.

    Viruses are considered key players in phytoplankton population control in oceans. However, mechanisms that control viral gene expression in prominent microalgae such as diatoms remain largely unknown. In this study, potential promoter regions isolated from several marine diatom-infecting viruses (DIVs) were linked to the egfp reporter gene and transformed into the Pennales diatom Phaeodactylum tricornutum. We analysed their activity in cells grown under different conditions. Compared to diatom endogenous promoters, novel DIV promoter (ClP1) mediated a significantly higher degree of reporter transcription and translation. Stable expression levels were observed in transformants grown under both light and dark conditions, and high levels of expression were reported in cells in the stationary phase compared to the exponential phase of growth. Conserved motifs in the sequence of DIV promoters were also found. These results allow the identification of novel regulatory regions that drive DIV gene expression and further examinations of the mechanisms that control virus-mediated bloom control in diatoms. Moreover, the identified ClP1 promoter can serve as a novel tool for metabolic engineering of diatoms. This is the first report describing a promoter of DIVs that may be of use in basic and applied diatom research.

    Team-based healthcare delivery models, which emphasize care coordination, patient engagement, and utilization of health information technology, are emerging. To achieve these models, expertise in interprofessional education, collaborative practice across professions, and informatics is essential. This case study from informatics programs in the Academic Health Center (AHC) at the University of Minnesota and the Office of Health Information Technology (OHIT) at the Minnesota Department of Health presents an academic-practice partnership, which focuses on both interprofessionalism and informatics. Outcomes include the Minnesota Framework for Interprofessional Biomedical Health Informatics, comprising collaborative curriculum development, teaching and research, practicums to promote competencies, service to advance biomedical health informatics, and collaborative environments to facilitate a learning health system. Details on these Framework categories are presented. Partnership success is due to interprofessional connections created with emphasis on informatics and to committed leadership across partners. A limitation of this collaboration is the need for formal agreements outlining resources and roles, which are vital for sustainability. This partnership addresses a recommendation on the future of interprofessionalism: that both education and practice sectors be attuned to each other's expectations and evolving trends. Success strategies and lessons learned from collaborations, such as that of the AHC-OHIT that promote both interprofessionalism and informatics, need to be shared.

    The adoption of a healthy lifestyle, including physical activity, a balanced diet, a moderate alcohol consumption and abstinence from smoking, are associated with large decreases in the incidence and mortality rates for the most common chronic diseases. That is why primary health care (PHC) services are trying, so far with less success than desirable, to promote healthy lifestyles among patients. The objective of this study is to design and model, under a participative collaboration framework between clinicians and researchers, interventions that are feasible and sustainable for the promotion of healthy lifestyles in PHC. Phase I formative research and a quasi-experimental evaluation of the modelling and planning process will be undertaken in eight primary care centres (PCCs) of the Basque Health Service--OSAKIDETZA, of which four centres will be assigned for convenience to the Intervention Group (the others being Controls). Twelve structured study, discussion and consensus sessions supported by reviews of the literature and relevant documents, will be undertaken throughout 12 months. The first four sessions, including a descriptive strategic needs assessment, will lead to the prioritisation of a health promotion aim in each centre. In the remaining eight sessions, collaborative design of intervention strategies, on the basis of a planning process and pilot trials, will be carried out. The impact of the formative process on the practice of healthy lifestyle promotion, attitude towards health promotion and other factors associated with the optimisation of preventive clinical practice will be assessed, through pre- and post-programme evaluations and comparisons of the indicators measured in professionals from the centres assigned to the Intervention or Control Groups. There are four necessary factors for the outcome to be successful and result in important changes: (1) the commitment of professional and community partners who are involved; (2) their competence for

    A cross-sectional descriptive study was done using the Acculturation Rating scale of Arab Americans-II, and the Health Promotion and Lifestyle Profile II to assess the relationship between acculturation and health promotion practices among Arab Americans. Findings showed that attraction to American culture was the most important predictor of physical activity; whereas attraction to Arabic culture was the most important predictor of stress management and nutritional practices. Results suggest that, when demographics are controlled, acculturation predicts various health promotion practices in different patterns among members of this group. These findings contribute to a better understanding of acculturation's influence on immigrants' health promotion practices.

    Radiation Technology (RT) has been widely used in most of all fields of industries, medical, bioresources, food and agriculture, public hygiene, and environment. Therefore, its application has been also researched in various parts. For industrialization of the developed technology, not only the application technology will be developed, but the accurate dosimetry and improvement of the services of irradiation practice should be performed as soon as possible. Evaluation of effects and reaction mechanism of biological materials by irradiation was performed in this year in the long term research planning. The researches and experiments were well performed and the good results were obtained. The results may be donated in the progress of radiation biology and the new establishment on the application of RT. Also, one of the results was the evaluation of the structural changes of biomolecules and its application in the fields of food and biotechnology industries.

    The purpose of the present study was to pilot a prevention program designed to promote positive body image among university students. Thirty-seven undergraduate students from three Canadian universities were recruited to participate in the study. They were selected from a pool of students enrolled in a peer health education program facilitated by the university-based health promotion staff. Borrowing from the tenets of the non-specific vulnerability stressor model and the disease-specific social cognitive theory, the intervention focused on media literacy, self-esteem enhancement strategies, stress management skills and ways to recognize healthy versus unhealthy relationships. Separate ANOVAs revealed that participants reported significant improvements in body satisfaction and reductions in the internalization of media stereotypes between the baseline and post-program period. The program received a favorable response from the participating students, who appreciated the face-to-face format of the intervention, and from the university staff who expressed interest in embedding the strategies into their routine peer mentoring training activities. Limitations of the study and suggestions for future research are discussed. 2010. Published by Elsevier Ltd. All rights reserved.

    Full Text Available Abstract Background Health promotion is critical for community and family health. Health-promoting behaviours provide solutions for maintaining and promoting health. Although several studies have addressed the frequency and different types of health-promoting behaviours in women, little information is available about their experiences. This study aimed to explore the experiences of women of reproductive age regarding health-promoting behaviours. Methods In the present study, which was conducted in Tehran, Iran, 15 females, who were selected purposefully, participated in individual in-depth, semi-structured interviews. The interviews were recorded, transcribed verbatim, and analysed using conventional content analysis. Results Nine main categories were derived from the analysis, including establishing an appropriate eating pattern, establishing a balanced rest/activity pattern, spirituality, stress management, personal sensitivity and responsibility, establishing an appropriate pattern of social interactions, practicing safe and healthy recreations, feeling improvement in physical-functional health, and feeling improvement in emotional and psychological health. The first 7 categories represent the nature and types of real health-promoting behaviours in women of reproductive age, whereas the last 2 constitute feeling and understanding of the implementation of these behaviours. Conclusion The study findings show that the women experience improvement in physical-functional, emotional, and psychological health by implementing health-promoting behaviours. It is therefore necessary to introduce strategies in the context of the community culture for improving different aspects of health-promoting behaviours in women of reproductive age to maintain and improve their overall health.

    Health promotion is critical for community and family health. Health-promoting behaviours provide solutions for maintaining and promoting health. Although several studies have addressed the frequency and different types of health-promoting behaviours in women, little information is available about their experiences. This study aimed to explore the experiences of women of reproductive age regarding health-promoting behaviours. In the present study, which was conducted in Tehran, Iran, 15 females, who were selected purposefully, participated in individual in-depth, semi-structured interviews. The interviews were recorded, transcribed verbatim, and analysed using conventional content analysis. Nine main categories were derived from the analysis, including establishing an appropriate eating pattern, establishing a balanced rest/activity pattern, spirituality, stress management, personal sensitivity and responsibility, establishing an appropriate pattern of social interactions, practicing safe and healthy recreations, feeling improvement in physical-functional health, and feeling improvement in emotional and psychological health. The first 7 categories represent the nature and types of real health-promoting behaviours in women of reproductive age, whereas the last 2 constitute feeling and understanding of the implementation of these behaviours.

    To develop an instrument for measuring Health Promotion Model constructs in terms of breakfast consumption, and to identify the constructs that were predictors of breakfast consumption among Iranian female students. A questionnaire on Health Promotion Model variables was developed and potential predictors of breakfast consumption were assessed using this tool. One hundred female students, mean age 13 years (SD ± 1.2 years). Two middle schools from moderate-income areas in Qom, Iran. Health Promotion Model variables were assessed using a 58-item questionnaire. Breakfast consumption was also measured. Internal consistency (Cronbach alpha), content validity index, content validity ratio, multiple linear regression using stepwise method, and Pearson correlation. Content validity index and content validity ratio scores of the developed scale items were 0.89 and 0.93, respectively. Internal consistencies (range, .74-.91) of subscales were acceptable. Prior related behaviors, perceived barriers, self-efficacy, and competing demand and preferences were 4 constructs that could predict 63% variance of breakfast frequency per week among subjects. The instrument developed in this study may be a useful tool for researchers to explore factors affecting breakfast consumption among students. Students with a high level of self-efficacy, more prior related behavior, fewer perceived barriers, and fewer competing demands were most likely to regularly consume breakfast.

    Perception is the most important predictor of behavior and there is a strong relation and correlation between behavior and believes. Thus, to improve self-care behaviors of patients, it is required to fully understand their perceptions about behavior. This paper aimed to assess the prediction power of health promotion model of systolic blood pressure (SBP) as the result of self-care behavior in rural hypertensive. This cross-sectional study has been carried out through random multistage sampling on 671 rural patients under the coverage of health center of Ardebil city in 2013. Data were collected through reliable and valid questionnaire based on the health promotion model in eight sectors. For data analysis, Pearson correlation statistical tests, multivariate linear regression, ANOVA and independent t-test were used and for confirmatory factor analysis, SPSS 18 and AMOS 18 (SPSS Inc., Chicago, IL, USA) were used. The results showed significant negative correlation between self-efficacy, perceived benefits, situational influences, affects related to behavior and commitment to action structures with SBP and showed a positive significant correlation between perceived barriers and SBP. Furthermore, age and body mass had direct significant relation with SBP. The age of patients showed inverse significant correlation with self-efficacy, perceived benefits, affects related to behavior, interpersonal influences and commitment and showed a direct significant correlation with perceived barriers, means that by increase of age, the perceived barriers also increased. The structures of health promotion model have in overall the prediction power of 71.4% of SBP changes. The diet perceptions of patients, the same as health promotion model, has good predictive power of SBP, especially the structures of perceived benefits and self-efficacy have inverse meaningful relation with systole blood pressure and predicted a higher percentage of this variable.

    OBJECTIVE: Most people maintain almost constant body weight over long time with varying physical activity and food intake. This indicates the existence of a regulation that works well for most individuals. Yet some people develop obesity, indicating that this regulation sometimes fails...... expenditure and energy intake. Dependent on the precise balance between these effects of weight gain, they may make the body weight unstable and tend to further promote weight gain. With the aim of identifying the thresholds beyond which such self-promoting weight gain may take place, we develop a simple...... mathematical model of the body as an energy-consuming machine in which the changes in physical activity and food intake are described as feedback effects in addition to the effect of the weight gain on basal metabolic rate. The feedback parameters of the model may differ between individuals and only in some...

    Full Text Available Although active life style is one of the main determining factors of health, the level of regular physical activities in women is less than in men and even this level decreases with aging. The aim of this study was to determine the effect of an intervention based on the social ecological model on promotion of physical activity among female employees. In this study, 160 women employed at Shabestar universities were selected, and randomly divided into two groups of control (n=80 and intervention (n=80. The intervention group received an instructional program according to the model, including one session for general instruction and four sessions for group discussion along with daily walking for 30 minutes within 8 weeks. In order to objectively measure the physical activity, the pedometer was used and to measure the perceived physical activity, the long form of International Physical Activity Questionnaire (IPAQ was applied. The variables related to the components of socio-ecological model were measured using the socio-ecological model questionnaire. A significant difference was found between two groups after the intervention in terms of That is, the average number of steps in walking in the intervention group increased significantly (from 4204 to 7882 steps per day, while it did not significantly increase in the control group. Thus, it can be argued that designing and implementing the interventional programs based on the socio-ecological model can promote physical activity behavior among employed women

    As public expectations for health rise, health measurements broaden from a focus on death, disease, and disability to wellbeing. However, wellbeing hasn't been incorporated into the framework of climate change policy decision-making in Chinese cities. Based on survey data (n = 763) from Suzhou, this study used Generalized Estimation Equation approach to model external conditions associated with wellbeing. Then, semi-quantitative analyses were conducted to provide a first indication to whether local climate change policies promote or conflict with wellbeing through altering these conditions. Our findings suggested: (i) Socio-demographic (age, job satisfaction, health), psychosocial (satisfaction with social life, ontological security/resilience) and environmental conditions (distance to busy road, noise annoyance and range hoods in the kitchen) were significantly associated with wellbeing; (ii) None of existing climate change strategies in Suzhou conflict with wellbeing. Three mitigation policies (promotion of tertiary and high-tech industry, increased renewable energy in buildings, and restrictions on car use) and one adaption policy (increasing resilience) brought positive co-benefits for wellbeing, through the availability of high-satisfied jobs, reduced dependence on range hoods, noise reduction, and valuing citizens, respectively. This study also provided implications for other similar Chinese cities that potential consequences of climate change interventions for wellbeing should be considered.

    Chitosan has been degraded to produced oligo chitosan with different molecular weight using gamma ray irradiation from a Co-60 source in solid state (powder form) and liquid state (aqueous solution). Study on growth promotion of paddy plants was done using oligo chitosan and conventional plant growth promoter as a comparison. Oligo chitosan was used with different molecular weight and different concentrations. Smaller molecular weight of oligo chitosan with smaller concentration showed better result than bigger molecular weight of oligo chitosan as a plant growth promoter. This study also showed that conventional growth promoter can be replaced with oligo chitosan as it is more effective as plant growth promoter as well as more environmental friendly. (author)

    Health care leaders and providers have introduced the assumption the typical elder, even in the presence of complex, chronic disease and prevailing illness, is capable of assuming greater personal responsibility for their health care, with a shift from provider-centered to a person-centered model of care. For older adults who often and repeatedly face challenges managing and maintaining their health status, guidance and support is needed. In this study, COLLAGE 360 , a comprehensive assessment system and wellness coaching program that focuses on prevention and wellness, care coordination and self-management of health care was implemented in one continuing care retirement community. Following completion of two assessment tools via directed conversation with a wellness coach, older adults developed an individualized vitality plan that outlined life goals, supporting goals and action plans for goal achievement. Results from this program suggest engagement in the assessment and wellness coaching process via the COLLAGE 360 program translated into sample older adults sensing that they live in a more supportive environment when compared with elders not receiving any wellness coaching. In addition, the older adults had positive effects in the areas of mood, loneliness, social interaction, health status, and life satisfaction. Strategies to improve health and well being need an extended focus beyond the older adult's medical conditions and consider psychological, spiritual and social needs with personal preferences being paramount. These issues are foundational to a person-centered, health promotion approach needed among this population.

    To evaluate the impact of the Calgary Health Region Collective Kitchen Program on various Population Health Promotion Model health determinants, data were collected through mail-in questionnaires that examined the members' (n=331) and coordinators' (n=58) perspectives of the program. Seventy-nine members (24%) and 26 coordinators (45%) were included in the study. Three incomplete questionnaires (from prenatal program members) were discarded. Sixty-one percent of members who reported income level and family size (n=61) had incomes below the low-income cut-off. Fifty-eight members (73%) reported improvements in their lives because of the program. Sixty-four members (81%) perceived they learned to feed their families healthier foods. The members reported their fruit and vegetable consumption before and since joining a collective kitchen, and the proportion of those consuming at least five fruit and vegetable servings a day rose from 29% to 47%. The most common reasons for joining this program concerned social interactions and support. Over 90% of the coordinators perceived that they were competent to coordinate a kitchen. The results indicate that the collective kitchens program addresses several health determinants, and may increase members' capacity to attain food security and to achieve improved nutritional health.

    Antihypertensive medications are widely prescribed by doctors and heavily promoted by the pharmaceutical industry. Despite strong evidence of the effectiveness and cost-effectiveness of thiazide diuretics, trends in both promotion and prescription of antihypertensive drugs favour newer, less cost-effective agents. Observational evidence shows correlations between exposure to pharmaceutical promotion and less ideal prescribing. Our study therefore aimed to determine whether print advertisements for antihypertensive medications promote quality prescribing in hypertension. We performed a cross-sectional study of 113 advertisements for antihypertensive drugs from 4 general practice-oriented Australian medical publications in 2004. Advertisements were evaluated using a quality checklist based on a review of hypertension management guidelines. Main outcome measures included: frequency with which antihypertensive classes were advertised, promotion of thiazide class drugs as first line agents, use of statistical claims in advertisements, mention of harms and prices in the advertisements, promotion of assessment and treatment of cardiovascular risk, promotion of lifestyle modification, and targeting of particular patient subgroups. Thiazides were the most frequently advertised drug class (48.7% of advertisements), but were largely promoted in combination preparations. The only thiazide advertised as a single agent was the most expensive, indapamide. No advertisement specifically promoted any thiazide as a better first-line drug. Statistics in the advertisements tended to be expressed in relative rather than absolute terms. Drug costs were often reported, but without cost comparisons between drugs. Adverse effects were usually reported but largely confined to the advertisements' small print. Other than mentioning drug interactions with alcohol and salt, no advertisements promoted lifestyle modification. Few advertisements (2.7%) promoted the assessment of cardiovascular risk

    Full Text Available Previous studies have used the zebrafish to investigate the biology of lens crystallin proteins and their roles in development and disease. However, little is known about zebrafish α-crystallin promoter function, how it compares to that of mammals, or whether mammalian α-crystallin promoter activity can be assessed using zebrafish embryos. We injected a variety of α-crystallin promoter fragments from each species combined with the coding sequence for green fluorescent protein (GFP into zebrafish zygotes to determine the resulting spatiotemporal expression patterns in the developing embryo. We also measured mRNA levels and protein abundance for all three zebrafish α-crystallins. Our data showed that mouse and zebrafish αA-crystallin promoters generated similar GFP expression in the lens, but with earlier onset when using mouse promoters. Expression was also found in notochord and skeletal muscle in a smaller percentage of embryos. Mouse αB-crystallin promoter fragments drove GFP expression primarily in zebrafish skeletal muscle, with less common expression in notochord, lens, heart and in extraocular regions of the eye. A short fragment containing only a lens-specific enhancer region increased lens and notochord GFP expression while decreasing muscle expression, suggesting that the influence of mouse promoter control regions carries over into zebrafish embryos. The two paralogous zebrafish αB-crystallin promoters produced subtly different expression profiles, with the aBa promoter driving expression equally in notochord and skeletal muscle while the αBb promoter resulted primarily in skeletal muscle expression. Messenger RNA for zebrafish αA increased between 1 and 2 days post fertilization (dpf, αBa increased between 4 and 5 dpf, but αBb remained at baseline levels through 5 dpf. Parallel reaction monitoring (PRM mass spectrometry was used to detect αA, aBa, and αBb peptides in digests of zebrafish embryos. In whole embryos,

    Based on his early graduated studies in psychophysics, the author has, in recent years, applied psychophysics for studying organic and motor senses (the two sensory systems deeply embedded inside of human body), and tried to understand the scientific foundation of the oriental health promoting practices. The preliminary results are promising and are discussed in detail in this paper. Psychophysics studies of organic and motor senses may be the tool to provide the connection between Western and Eastern medicines to form a balanced holistic medicine approach, and may help us to understand the scientific foundation of mysterious oriental health Promoting practices that serve as alternative medicines for promoting human wellness against illness.

  2. Strategies for Promoting Green Building Technologies Adoption in the Construction Industry—An International Study

    Full Text Available Because green building technologies (GBTs adoption is a promising way of ameliorating the sustainability performance of buildings, GBTs are receiving increased interest in the global construction community. The barriers to the adoption of GBTs, such as higher cost and lack of awareness, further indicate that proper strategies need to be devised for promoting the wider adoption of GBTs in buildings development. However, there exist limited empirical studies identifying the strategies for promoting GBTs adoption in the construction industry. This study aims to identify the strategies that are important for promoting GBTs adoption in construction. After a comprehensive literature review to identify strategies for the promotion of GBTs adoption, empirical data were gleaned through a questionnaire survey with 104 green building experts around the world. The analysis results validated the importance of all of the 12 promotion strategies used for the study. Green building experts from different countries and with different backgrounds had significant agreement on the relative importance ranking of the promotion strategies. Furthermore, “financial and further market-based incentives for GBTs adopters”, “availability of better information on cost and benefits of GBTs”, “mandatory governmental policies and regulations”, and “green rating and labeling” were identified as the top four important promotion strategies. The research findings provide a valuable reference to assist practitioners and policy makers in developing practical strategies for promoting GBTs adoption to eventually achieve the sustainable development of buildings. From the perspective of international experts, this study adds to the green building literature by offering empirical evidence of the important strategies for promoting GBTs adoption in the construction industry. Future research will investigate the interrelationships among the promotion strategies and their

    2018-01-01

    Background In the recent years, social networking sites (SNSs, also called social media) have been adopted in organ donation campaigns, and recruiting opinion leaders for such campaigns has been found effective in promoting behavioral changes. Objective The aim of this paper was to focus on the dissemination of organ donation tweets on Weibo, the Chinese equivalent of Twitter, and to examine the opinion leadership in the retweet network of popular organ donation messages using social network analysis. It also aimed to investigate how personal and social attributes contribute to a user’s opinion leadership on the topic of organ donation. Methods All messages about organ donation posted on Weibo from January 1, 2015 to December 31, 2015 were extracted using Python Web crawler.

    In the recent years, social networking sites (SNSs, also called social media) have been adopted in organ donation campaigns, and recruiting opinion leaders for such campaigns has been found effective in promoting behavioral changes. The aim of this paper was to focus on the dissemination of organ donation tweets on Weibo, the Chinese equivalent of Twitter, and to examine the opinion leadership in the retweet network of popular organ donation messages using social network analysis. It also aimed to investigate how personal and social attributes contribute to a user's opinion leadership on the topic of organ donation. All messages about organ donation posted on Weibo from January 1, 2015 to December 31, 2015 were extracted using Python Web crawler. A retweet network with 505,047 nodes and 545,312 edges of the popular messages (n=206) was constructed and analyzed. The local and global opinion leaderships were measured using network metrics, and the roles of personal attributes, professional knowledge, and social positions in obtaining the opinion leadership were examined using general linear model. The findings revealed that personal attributes, professional knowledge, and social positions predicted individual's local opinion leadership in the retweet network of popular organ donation messages. Alternatively, personal attributes and social positions, but not professional knowledge, were significantly associated with global opinion leadership. The findings of this study indicate that health campaign designers may recruit peer leaders in SNS organ donation promotions to facilitate information sharing among the target audience. Users who are unverified, active, well connected, and experienced with information and communications technology (ICT) will accelerate the sharing of organ donation messages in the global environment.

    Our group has reported that mature adipocyte-derived dedifferentiated fat (DFAT) cells show multilineage differentiation potential similar to that observed in mesenchymal stem cells. In the present study, we examined whether DFAT cell transplantation could contribute to intervertebral disc regeneration using a rat intervertebral disc degeneration (IDD) model. The IDD was created in Sprague-Dawley rats by puncturing at level of caudal intervertebral disc under fluoroscopy. One week after injury, rat DFAT cells (5 × 10 4 , DFAT group, n = 13) or phosphate-buffered saline (PBS, control group, n = 13) were injected into the intervertebral disc. Percent disc height index (%DHI) was measured every week and histology of injured disc was evaluated at 8 weeks after transplantation. Radiographic analysis revealed that the %DHI in the DFAT group significantly higher than that in the control group at 2-3 weeks after transplantation. Histological analysis revealed that ectopic formation of nucleus pulposus (NP)-like tissue at the outer layer of annulus fibrosus was frequently observed in the DFAT group but not in the control group. Transplantation experiments using green fluorescent protein (GFP)-labeled DFAT cells revealed that the ectopic NP-like tissue was positive for GFP, suggesting direct differentiation of DFAT cells into NP-like cells. In conclusion, DFAT cell transplantation promoted the regeneration of intervertebral disc and improved intervertebral disc height in the rat IDD model. Because adipose tissue is abundant and easily accessible, DFAT cell transplantation may be an attractive therapeutic strategy against IDD. Copyright © 2017 The Authors. Published by Elsevier Inc.

    Nonalcoholic steatohepatitis (NASH) patients progress to liver cirrhosis and even hepatocellular carcinoma (HCC). Several lines of evidence indicate that accumulation of lipopolysaccharide (LPS) and disruption of gut microbiota play contributory roles in HCC. Moreover, in a dextran sodium sulfate (DSS)-induced colitis model in mice, a high-fat diet increases portal LPS level and promotes hepatic inflammation and fibrosis. However, this diet-induced NASH model requires at least 50 weeks for carcinogenesis. In this study, we sought to determine whether increased intestinal permeability would aggravate liver inflammation and fibrosis and accelerate tumorigenesis in a diet-induced NASH model. Mice were fed a choline-deficient high-fat (CDHF) diet for 4 or 12 weeks. The DSS group was fed CDHF and intermittently received 1% DSS in the drinking water. Exposure to DSS promoted mucosal changes such as crypt loss and increased the number of inflammatory cells in the colon. In the DSS group, portal LPS levels were elevated at 4 weeks, and the proportions of Clostridium cluster XI in the fecal microbiota were elevated. In addition, levels of serum transaminase, number of lobular inflammatory cells, F4/80 staining-positive area, and levels of inflammatory cytokines were all elevated in the DSS group. Liver histology in the DSS group revealed severe fibrosis at 12 weeks. Liver tumors were detected in the DSS group at 12 weeks, but not in the other groups. Thus, DSS administration promoted liver tumors in a CDHF diet-induced NASH mouse over the short term, suggesting that the induction of intestinal inflammation and gut disruption of microbiota in NASH promote hepatic tumorigenesis.

    Evidence-based health promotion and prevention are the only means to meet the future economic challenges in health care. Since preventive measures do not penetrate all strata of society alike, the workplace is a probable platform for health education and promotion. Against this background, the network of the 'Erlangen Model' attempts to include health promotion as an integral part of enterprise policy; the present paper evaluates preliminary results of this programme. Questionnaires and interviews were conducted among employees of 6 companies and authorities forming the network "Agitating Enterprises". A total of 1,748 subjects were included and answered questions about their professional and health-related situation, physical activities, and expectations in connection with the programme. Almost half of the subjects (48%) had no intention to participate in one of the programme's courses. Most frequent mentioned reasons in favour of participation were the expectation of positive effects on general health (75%), well-being (78%), team work (32%) and enjoyment of sports (70%). Factor analysis extracted 5 dimensions of occupational burden out of over 50 items: "Co-operation with colleagues and superiors", "safety at work", "workflow organisation", "individual complaints" and "workplace design". Between participating companies the expression of these dimensions varied substantially; employees of the university hospital in general reported a higher-than-average burden. In contrast, differences regarding the health status, satisfaction with employment conditions and individual activity scores were minor. Health promotion at the workplace is meaningful, especially for health-care employees. Differential analyses of reasons for non-participation may reveal starting points for an improvement of attendance in health-promotion programmes. Copyright Georg Thieme Verlag KG Stuttgart .

    Implementing national policies may threaten the eligibility of renewable energy projects for Clean Development Mechanism/Joint Implementation (CDM/JI), thus reducing international development financing. Countries hence need to be very careful when crafting their national promotion policies. The objectives of the Renewable Energy Technology Deployment (IEA-RETD) project were to perform a scoping study on the interplay between national Renewable Energy (RE) promotion policies and international carbon trade. The study summarizes the ongoing discussion, describes the main barriers that may hinder -- or at least not sufficiently support -- the implementation of national RE promotion policies, and provides suggestions for removing these barriers.

    Non-communicable diseases are a leading cause of death and can largely be prevented by healthy lifestyles. Health care organizations are encouraged to integrate healthy lifestyle promotion in routine care. This study evaluates the impact of a team initiative on healthy lifestyle promotion in primary care. A quasi-experimental, cross-sectional design compared three intervention centres that had implemented lifestyle teams with three control centres that used a traditional model of care. Outcomes were defined using the RE-AIM framework: reach, the proportion of patients receiving lifestyle promotion; effectiveness, self-reported attitudes and competency among staff; adoption, proportion of staff reporting regular practice of lifestyle promotion; implementation, fidelity to the original lifestyle team protocol. Data collection methods included a patient questionnaire (n = 888), a staff questionnaire (n = 120) and structured interviews with all practice managers and, where applicable, team managers (n = 8). The chi square test and problem-driven content analysis was used to analyse the questionnaire and interview data, respectively. Reach: patients at control centres (48%, n = 211) received lifestyle promotion significantly more often compared with patients at intervention centres (41%, n = 169). Effectiveness: intervention staff was significantly more positive towards the effectiveness of lifestyle promotion, shared competency and how lifestyle promotion was prioritized at their centre. Adoption: 47% of staff at intervention centres and 58% at control centres reported that they asked patients about their lifestyle on a daily basis. all intervention centres had implemented multi-professional teams and team managers and held regular meetings but struggled to implement in-house referral structures for lifestyle promotion, which was used consistently among staff. Intervention centres did not show higher rates than control centres on reach of patients

    Motor electricity consumption is influenced by many factors including: motor efficiency, motor speed controls, power supply quality, harmonics, systems oversizing, distribution network, mechanical transmission system, maintenance practices, load management and cycling, and the efficiency of the end-use device (e.g. fan, pump, etc.). Due to their importance, an overview of these factors is presented in this report. This study also describes the electricity use in the industrial and tertiary sectors and the electricity consumption associated with the different types of electric motors systems in the Member States of the European Union, as well as estimated future evolution until 2010. The studies for individual countries were carried out by the different partners of the motors study group at a previous stage. The study has found that there is a lack of accurate information about the motor electricity consumption, installed motor capacity and the motor market in almost all the European Union countries and only some general statistical sources are available. There is little field data, which is mainly available in Denmark, France, Italy and the Netherlands. Due to this lack of primary information, some common assumptions were made, based on the experience of the members of the study group. This lack of end-use characterisation data shows the need for improvement from the point of view of current knowledge. It is therefore recommended that further research is undertaken to arrive at more accurate figures. These could be the basis for a better understanding for motor use in practice and - as a consequence - for a more precise appraisal of potentials and barriers to energy efficiency. (orig.)

    Full Text Available An influenza virus polymerase reconstitution assay based on the human, dog, or chicken RNA polymerase I (PolI promoter has been developed and widely used to study the polymerase activity of the influenza virus in corresponding cell types. Although it is an important member of the influenza virus family and has been known for sixty years, no studies have been performed to clone the horse PolI promoter or to study the polymerase activity of equine influenza virus (EIV in horse cells. In our study, the horse RNA PolI promoter was cloned from fetal equine lung cells. Using the luciferase assay, it was found that a 500 bp horse RNA PolI promoter sequence was required for efficient transcription. Then, using the developed polymerase reconstitution assay based on the horse RNA PolI promoter, the polymerase activity of two EIV strains was compared, and equine myxovirus resistance A protein was identified as having the inhibiting EIV polymerase activity function in horse cells. Our study enriches our knowledge of the RNA PolI promoter of eukaryotic species and provides a useful tool for the study of influenza virus polymerase activity in horse cells.

    1979-04-01

    The use of small obstacles to thin the downstream mass transfer boundary layer has been investigated with a traveling, dual-beam laser interferometer. Plots of boundary layer thickness as a function of the distance from the leading edge of the electrode were developed to study the effects of obstacle shape, the distance of the obstacle from the electrode surface, and Reynolds number for the purposes of determining the optimum conditions to achieve high mass transfer rates. Parameters which characterize the efficiency of the obstacles, the minimum boundary layer thickness in the wake, and the recovery distance downstream of each obstacle have been introduced to quantitatively describe the results. In addition, the effect of local turbulence near the obstacles on the deposit morphology has been described

    2017-12-01

    Empowering Effective STEM Role Models, a three-hour training developed and successfully implemented by NASA Langley Research Center's Science Directorate, is an effort to encourage STEM professionals to serve as role models within their community. The training is designed to help participants reflect on their identity as a role model and provide research-based strategies to effectively engage youth, particularly girls, in STEM (science, technology, engineering, and mathematics). Research shows that even though girls and boys do not demonstrate a significant difference in their ability to be successful in mathematics and science, there is a significant difference in their confidence level when participating in STEM subject matter and pursuing STEM careers. The Langley training model prepares professionals to disrupt this pattern and take on the habits and skills of effective role models. The training model is based on other successful models and resources for role modeling in STEM including SciGirls; the National Girls Collaborative; and publications by the American Association of University Women and the National Academies. It includes a significant reflection component, and participants walk through situation-based scenarios to practice a focused suite of research-based strategies. These strategies can be implemented in a variety of situations and adapted to the needs of groups that are underrepresented in STEM fields. Underpinning the training and the discussions is the fostering of a growth mindset and promoting perseverance. "The Power of Yet" becomes a means whereby role models encourage students to believe in themselves, working toward reaching their goals and dreams in the area of STEM. To provide additional support, NASA Langley role model trainers are available to work with a champion at other organizations to facilitate the training. This champion helps recruit participants, seeks leadership buy-in, and helps provide valuable insights for needs and

    2016-08-23

    Numerous studies have demonstrated that dietary intervention may promote health and help prevent Alzheimer's disease (AD). We recently reported that bee products of royal jelly (RJ) and enzyme-treated royal jelly (eRJ) were potent to promote healthy aging in C. elegans. Here, we examined whether RJ/eRJ consumption may benefit to mitigate the AD symptom in the disease model of C. elegans. Our results showed that RJ/eRJ supplementation significantly delayed the body paralysis in AD worms, suggesting the β-amyloid (Aβ) toxicity attenuation effects of RJ/eRJ. Genetic analyses suggested that RJ/eRJ-mediated alleviation of Aβ toxicity in AD worms required DAF-16, rather than HSF-1 and SKN-1, in an insulin/IGF signaling dependent manner. Moreover, RJ/eRJ modulated the transactivity of DAF-16 and dramatically improved the protein solubility in aged worms. Given protein solubility is a hallmark of healthy proteostasis, our findings demonstrated that RJ/eRJ supplementation improved proteostasis, and this promotion depended on the transactivity of DAF-16. Collectively, the present study not only elucidated the possible anti-AD mechanism of RJ/eRJ, but also provided evidence from a practical point of view to shed light on the extensive correlation of proteostasis and the prevention of neurodegenerative disorders.

    2011-11-01

    Science programmes which prepare students to read critically and respond thoughtfully to science-based reports in the media could play an important role in promoting informed participation in the public debate about issues relating to science, technology and society. Evidence based guidance about the practice and pattern of use of science-based media in the classroom is limited. This study sought to identify learning intentions that teachers believe ought to underpin the development of programmes of study designed to achieve this end-result. Teachers' views of knowledge, skills and attitudes required to engage critically with science-based news served as a basis for this study. Teachers developed a pedagogical model by selecting appropriate statements of learning intentions, grouping these into coherent and manageable themes and coding them according to perceived level of difficulty. The model is largely compatible with current curricular provision in the UK, highlights opportunities for interdisciplinary collaboration and illustrates the developmental nature of the topic.

    Full Text Available Background and Objectives: Menopause, the beginning of a new era in the life of a woman, like all the other stages of life can create some problems, which threaten the women's health. The aim of this study was to examine the effects of education on the awareness of female health volunteers about menopause in the city of Kashan based on the health promotion model in 2016. Materials and Methods: In this semi-experimental study, 280 female health volunteers in the cities of Kashan and Aran Bidgol were selected by simple random sampling in 2016. The health volunteers' knowledge of menopause was compared before and 6 months after the training. The theoretical framework used in this study was the structures of Pender's health promotion model. Data were collected through a questionnaire and analyzed using correlation tests and regression analysis with the SPSS software. Results: The results showed that the mean age of the participants was 30.05 ± 5.17 years (age range, 18–43. The mean score of knowledge before training was 7.6 ± 3.75 and after the intervention was 7.81 ± 6.4, which was increased. There was a significant difference between the mean scores of knowledge before and after the training (P < 0.001 and t = 33.5. The results showed a significant difference in the mean scores of the health promotion model before and after the training (P = 0.05. Conclusion: The results of the present study showed the positive impact of education based on the health promotion model on the knowledge of the volunteers about menopause. It is recommended that some training and research programs be performed to select the optimal training methods for volunteers, and strengthen their scientific knowledge and empower them. Given that the health volunteers have a close relationship with the community, training them can change the health behaviors, reduce the cost of healthcare, and improve the health status of the community.

    Full Text Available Abstract Background Promoter identification is a first step in the quest to explain gene regulation in bacteria. It has been demonstrated that the initiation of bacterial transcription depends upon the stability and topology of DNA in the promoter region as well as the binding affinity between the RNA polymerase σ-factor and promoter. However, promoter prediction algorithms to date have not explicitly used an ensemble of these factors as predictors. In addition, most promoter models have been trained on data from Escherichia coli. Although it has been shown that transcriptional mechanisms are similar among various bacteria, it is quite possible that the differences between Escherichia coli and Chlamydia trachomatis are large enough to recommend an organism-specific modeling effort. Results Here we present an iterative stochastic model building procedure that combines such biophysical metrics as DNA stability, curvature, twist and stress-induced DNA duplex destabilization along with duration hidden Markov model parameters to model Chlamydia trachomatis σ66 promoters from 29 experimentally verified sequences. Initially, iterative duration hidden Markov modeling of the training set sequences provides a scoring algorithm for Chlamydia trachomatis RNA polymerase σ66/DNA binding. Subsequently, an iterative application of Stepwise Binary Logistic Regression selects multiple promoter predictors and deletes/replaces training set sequences to determine an optimal training set. The resulting model predicts the final training set with a high degree of accuracy and provides insights into the structure of the promoter region. Model based genome-wide predictions are provided so that optimal promoter candidates can be experimentally evaluated, and refined models developed. Co-predictions with three other algorithms are also supplied to enhance reliability. Conclusion This strategy and resulting model support the conjecture that DNA biophysical properties

    Efforts to change policies and the environments in which people live, work, and play have gained increasing attention over the past several decades. Yet health promotion frameworks that illustrate the complex processes that produce health-enhancing structural changes are limited. Building on the experiences of health educators, community activists, and community-based researchers described in this supplement and elsewhere, as well as several political, social, and behavioral science theories, we propose a new framework to organize our thinking about producing policy, environmental, and other structural changes. We build on the social ecological model, a framework widely employed in public health research and practice, by turning it inside out, placing health-related and other social policies and environments at the center, and conceptualizing the ways in which individuals, their social networks, and organized groups produce a community context that fosters healthy policy and environmental development. We conclude by describing how health promotion practitioners and researchers can foster structural change by (1) conveying the health and social relevance of policy and environmental change initiatives, (2) building partnerships to support them, and (3) promoting more equitable distributions of the resources necessary for people to meet their daily needs, control their lives, and freely participate in the public sphere. © 2015 Society for Public Health Education.

    Full Text Available Inorganic phosphate (Pi is required by all living organisms for the development of organs such as bone, muscle, brain, and lungs, regulating the expression of several critical genes as well as signal transduction. However, little is known about the effects of prolonged dietary Pi consumption on lung cancer progression. This study investigated the effects of a high-phosphate diet (HPD in a mouse model of adenocarcinoma. K-rasLA1 mice were fed a normal diet (0.3% Pi or an HPD (1% Pi for 1, 2, or 4 months. Mice were then sacrificed and subjected to inductively coupled plasma mass/optical emission spectrometry and laser ablation inductively coupled plasma mass-spectrometry analyses, western blot analysis, histopathological, immunohistochemical, and immunocytochemical analyses to evaluate tumor formation and progression (including cell proliferation, angiogenesis, and apoptosis, changes in ion levels and metabolism, autophagy, epithelial-to-mesenchymal transition, and protein translation in the lungs. An HPD accelerated tumorigenesis, as evidenced by increased adenoma and adenocarcinoma rates as well as tumor size. However, after 4 months of the HPD, cell proliferation was arrested, and marked increases in liver and lung ion levels and in energy production via the tricarboxylic acid cycle in the liver were observed, which were accompanied by increased autophagy and decreased angiogenesis and apoptosis. These results indicate that an HPD initially promotes but later inhibits lung cancer progression because of metabolic adaptation leading to tumor cell quiescence. Moreover, the results suggest that carefully regulated Pi consumption are effective in lung cancer prevention.

    Predicting the significant determinants of health-related quality of life through the application of structural equation modeling in adolescents has received little attention in the health education and health promotion literature. The purpose of this study was to investigate the relationships between self-efficacy, barriers, social support, health-promoting lifestyle, and health-related quality of life among Iranian adolescent girls. Pender's health promotion model guided this study. This was a cross-sectional survey of 500 students who were recruited in Kashan, Iran. Their health-related quality of life was measured by using the Short Form Health Survey. A path analysis was conducted to predict the health-related quality of life determinants. The results indicated that 71% of the variance in health-related quality of life could be predicted by the variables. The results affirmed that self-efficacy was the most significant predictor of the students' health-related quality of life. It was concluded that interventions that are aimed at improving self-efficacy can lead to the enhancement of health-related quality of life among adolescent girls in the developing country of Iran. © 2011 Blackwell Publishing Asia Pty Ltd.

    Full Text Available Abstract Aims: Regular physical activity can reduce the burden of chronic diseases, such as heart disease, diabetes, and some cancers, and can prevent early death. This study examined the impact of performing health promotion model intervention on physical activity of the health volunteers. Materials & Methods: This cross-sectional research is part of a three-month Intervening study started in 2015 on 80 health volunteers in Torbat-e Jaam City, Iran, which was selected by multistage random sampling method and participants were divided into two interventional and control groups. A Demographic Questionnaire and The Persian version of International Physical Activity Questionnaire were used to collect data. The data was analyzed in SPSS 16 using independent T, Pearson's correlation coefficient and linear regression tests. Findings: Before the intervention the mean of perceived benefit score was 31.3±4.5 that was evaluated as “good” but self-efficacy and behavior scores were 5.8±4.1 and 912.4±750.8 that were assessed as “poor”. Physical activity had positive correlation with perceived benefits, self-efficacy, commitment, positive, emotion and situational influences and a negative correlation with perceived barriers. Overall 66.8% of the physical activity was predicted by Pender’s Health Promotion Model variables. There was a significant difference between the mean scores of physical activity and other structures of HPM in the experimental group after the intervention and its score before intervention. Conclusion: Educational program based on Pender's health promotion model is effective in improving physical activity of health volunteers.

    The relevance of DNA methylation of O 6 -methylguanine-DNA methyltransferase (MGMT) in relation to several cancers and other disorders has been extensively explored in several cancer types. To ascertain the significance of DNA methylation of MGMT promoter in oral squamous cell carcinoma (OSCC), we undertook a study to a) analyse the methylation patterns of MGMT gene promoter in afflicted and normal population of coastal Karnataka, b) determine the expression status of MGMT in oral cancer cell lines (CAL-27 and SCC-4) and its relationship to DNA methylation and c) performed a meta-analysis of the published data. Bisulfite sequencing of MGMT promoter region was performed on non-malignant/malignant oral samples, and oral cancer cell lines, followed by gene expression studies. Further, using a systematic search, 1024 publications were retrieved from PubMed, Scopus, Google Scholar and Web of Science and 23 relevant articles were reviewed. Significant association of MGMT promoter methylation with OSCC (pMGMT gene promoter. Overall, we obtained a statistically significant (pMGMT DNA promoter methylation in oral cancer cases without publication bias. Gene expression was significantly elevated in both oral cancer cell lines (pMGMT may associate with recursive mutagenesis and is a promising biomarker for OSCC prediction.

    2009-01-01

    Full Text Available Abstract Background Healthy Schools programmes may assist schools in improving the oral health of children through advocating a common risk factor approach to health promotion and by more explicit consideration of oral health. The objectives of this study were to gain a broad contextual understanding of issues around the delivery of oral health promotion as part of Healthy Schools programmes and to investigate the barriers and drivers to the incorporation of oral health promoting activities in schools taking this holistic approach to health promotion. Methods Semi-structured telephone interviews were carried out with coordinators of Healthy Schools programmes in the Northwest of England. Interview transcripts were coded using a framework derived from themes in the interview schedule. Results All 22 Healthy Schools coordinators participated and all reported some engagement of their Healthy Schools scheme with oral health promotion. The degree of this engagement depended on factors such as historical patterns of working, partnerships, resources and priorities. Primary schools were reported to have engaged more fully with both Healthy Schools programmes and aspects of oral health promotion than secondary schools. Participants identified healthy eating interventions as the most appropriate means to promote oral health in schools. Partners with expertise in oral health were key in supporting Healthy Schools programmes to promote oral health. Conclusion Healthy Schools programmes are supporting the promotion of oral health although the extent to which this is happening is variable. Structures should be put in place to ensure that the engagement of Healthy Schools with oral health is fully supported.

    Traditional Chinese medicine has accumulated rich experience in treating dysfunction of gastrointestinal peristalsis. In recent years, a large number of studies have been made on the mechanism and effects of traditional Chinese medicines on the gastrointestinal peristalsis, and the concept of "gastrointestinal promoting Chinese medicine" has been advocated. These traditional Chinese medicines can be divided into three types: promoting the gastrointestinal peristalsis, inhibiting the gastrointestinal peristalsis, and bi-directional modulating. The in vivo and/or in vitro experiments showed that some of the traditional Chinese medicines for activating blood or regulating qi could promote the stomach peristalsis, and the traditional Chinese medicines for moistening intestines to relieve constipation or invigorating spleen to promote digestion could accelerate the intestinal peristalsis. The mechanism lies in the neuroregulation and gut-peptide regulation. Further research on multi-regulation and of multi-target should be done, for the mechanism of the traditional Chinese medicines in regulating the gastrointestinal peristalsis is far more complicated.

  3. FXN Promoter Silencing in the Humanized Mouse Model of Friedreich Ataxia.

    Directory of Open Access Journals (Sweden)

    Yogesh K Chutake

    Full Text Available Friedreich ataxia is caused by an expanded GAA triplet-repeat sequence in intron 1 of the FXN gene that results in epigenetic silencing of the FXN promoter. This silencing mechanism is seen in patient-derived lymphoblastoid cells but it remains unknown if it is a widespread phenomenon affecting multiple cell types and tissues.The humanized mouse model of Friedreich ataxia (YG8sR, which carries a single transgenic insert of the human FXN gene with an expanded GAA triplet-repeat in intron 1, is deficient for FXN transcript when compared to an isogenic transgenic mouse lacking the expanded repeat (Y47R. We found that in YG8sR the deficiency of FXN transcript extended both upstream and downstream of the expanded GAA triplet-repeat, suggestive of deficient transcriptional initiation. This pattern of deficiency was seen in all tissues tested, irrespective of whether they are known to be affected or spared in disease pathogenesis, in both neuronal and non-neuronal tissues, and in cultured primary fibroblasts. FXN promoter function was directly measured via metabolic labeling of newly synthesized transcripts in fibroblasts, which revealed that the YG8sR mouse was significantly deficient in transcriptional initiation compared to the Y47R mouse.Deficient transcriptional initiation accounts for FXN transcriptional deficiency in the humanized mouse model of Friedreich ataxia, similar to patient-derived cells, and the mechanism underlying promoter silencing in Friedreich ataxia is widespread across multiple cell types and tissues.

    Full Text Available Abstract Background The adoption of a healthy lifestyle, including physical activity, a balanced diet, a moderate alcohol consumption and abstinence from smoking, are associated with large decreases in the incidence and mortality rates for the most common chronic diseases. That is why primary health care (PHC services are trying, so far with less success than desirable, to promote healthy lifestyles among patients. The objective of this study is to design and model, under a participative collaboration framework between clinicians and researchers, interventions that are feasible and sustainable for the promotion of healthy lifestyles in PHC. Methods and design Phase I formative research and a quasi-experimental evaluation of the modelling and planning process will be undertaken in eight primary care centres (PCCs of the Basque Health Service – OSAKIDETZA, of which four centres will be assigned for convenience to the Intervention Group (the others being Controls. Twelve structured study, discussion and consensus sessions supported by reviews of the literature and relevant documents, will be undertaken throughout 12 months. The first four sessions, including a descriptive strategic needs assessment, will lead to the prioritisation of a health promotion aim in each centre. In the remaining eight sessions, collaborative design of intervention strategies, on the basis of a planning process and pilot trials, will be carried out. The impact of the formative process on the practice of healthy lifestyle promotion, attitude towards health promotion and other factors associated with the optimisation of preventive clinical practice will be assessed, through pre- and post-programme evaluations and comparisons of the indicators measured in professionals from the centres assigned to the Intervention or Control Groups.

    The resident skin microbiota plays an important role in restricting pathogenic bacteria, thereby protecting the host. Scabies mites (Sarcoptes scabiei) are thought to promote bacterial infections by breaching the skin barrier and excreting molecules that inhibit host innate immune responses. Epidemiological studies in humans confirm increased incidence of impetigo, generally caused by Staphylococcus aureus and Streptococcus pyogenes, secondary to the epidermal infestation with the parasitic mite. It is therefore possible that mite infestation could alter the healthy skin microbiota making way for the opportunistic pathogens. A longitudinal study to test this hypothesis in humans is near impossible due to ethical reasons. In a porcine model we generated scabies infestations closely resembling the disease manifestation in humans and investigated the scabies associated changes in the skin microbiota over the course of a mite infestation. In a 21 week trial, skin scrapings were collected from pigs infected with S. scabies var. suis and scabies-free control animals. A total of 96 skin scrapings were collected before, during infection and after acaricide treatment, and analyzed by bacterial 16S rDNA tag-encoded FLX-titanium amplicon pyrosequencing. We found significant changes in the epidermal microbiota, in particular a dramatic increase in Staphylococcus correlating with the onset of mite infestation in animals challenged with scabies mites. This increase persisted beyond treatment from mite infection and healing of skin. Furthermore, the staphylococci population shifted from the commensal S. hominis on the healthy skin prior to scabies mite challenge to S. chromogenes, which is increasingly recognized as being pathogenic, coinciding with scabies infection in pigs. In contrast, all animals in the scabies-free cohort remained relatively free of Staphylococcus throughout the trial. This is the first experimental in vivo evidence supporting previous assumptions that

    This paper revisits the debate on health and economic growth (Deaton in J Econ Lit 51:113-158, 2003) focusing on the Portuguese case by testing the relationship between growth and health. We test Portuguese insights, using time series data from 1960 to 2005, taking into account different variables (life expectancy, labour, capital, infant mortality) and considering the years that included major events on the political scene, such as the dictatorship and a closed economy (1960-1974), a revolution (1974) and full democracy and an open economy (1975-2005), factors that influence major economic, cultural, social and politic indicators. Therefore the analysis is carried out adopting Lucas' (J Monet Econ 22(1):3-42, 1988) endogenous growth model that considers human capital as one factor of production, it adopts a VAR (vector autoregressive) model to test the causality between growth and health. Estimates based on the VAR seem to confirm that economic growth influences the health process, but health does not promote growth, during the period under study.

    Thrombotic diseases in different forms become a great threat to human health. Such anti-platelet aggregation drugs as aspirin and clopidogrel are common drugs in clinic. However, along with the appearance of resistance and side effects of western anti-platelet aggregation drugs, anti-platelet aggregation traditional Chinese medicines promoting blood circulation to remove blood stasis have gradually become an important study orientation. Platelet is one of major participant in thrombosis, and plays an important role as a bioactive material in studies on traditional Chinese medicines promoting blood circulation to remove blood stasis, mainly involving two aspects--the evaluation for the anti-platelet aggregation activity of traditional Chinese medicines and the screening of their active components. This paper summarized the applications of platelets in studies on traditional Chinese medicines promoting blood circulation to remove blood stasis, so as to provide basis for further studies.

    In 2009, the International Union Against Tuberculosis and Lung Disease (The Union) and Médecins Sans Frontières (MSF) jointly developed a new paradigm for operational research (OR) capacity building and started a new process of appointing and supporting OR fellows in the field. This case study describes 1) the appointment of two OR fellows in The Union South-East Asia Office (USEA), New Delhi, India; 2) how this led to the development of an OR unit in that organisation; 3) achievements over the 5-year period from June 2009 to June 2014; and 4) challenges and lessons learnt. In June 2009, the first OR fellow in India was appointed on a full-time basis and the second was appointed in February 2012—both had limited previous experience in OR. From 2009 to 2014, annual research output and capacity building initiatives rose exponentially, and included 1) facilitation at 61 OR training courses/modules; 2) publication of 96 papers, several of which had a lasting impact on national policy and practice; 3) providing technical assistance in promoting OR; 4) building the capacity of medical college professionals in data management; 5) support to programme staff for disseminating their research findings; 6) reviewing 28 scientific papers for national or international peer-reviewed journals; and 7) developing 45 scientific abstracts for presentation at national and international conferences. The reasons for this success are highlighted along with ongoing challenges. This experience from India provides good evidence for promoting similar models elsewhere. PMID:26400596

    To arrive at an expert consensus in relation to health promotion and health education constructs as they apply to nursing practice, education and policy. Nursing has often been maligned and criticized, both inside and outside of the profession, for its ability to understand and conduct effective health promotion and health education-related activities. In the absence of an expert-based consensus, nurses may find it difficult to progress beyond the current situation. In the absence of any previously published nursing-related consensus research, this study seeks to fill that knowledge-gap. A two-round Delphi technique via email correspondence. A first-round qualitative questionnaire used open-ended questions for defining health promotion and health education. This was both in general terms and as participants believed these concepts related to the clinical, theoretical (academic/educational) and the policy (political) setting in nursing. Line-by-line qualitative content and thematic analysis of the first-round data generated 13 specific categories. These categories contained 134 statement items. The second-round questionnaire comprised the identified 134 statements. Using a five-point Likert scale (ranging from 1 = strongly disagree to 5 = strongly agree) participants scored and rated their level of agreement/disagreement against the listed items. Data from the second-round was descriptively analysed according to distribution and central tendency measures. An expert consensus was reached on 65 of the original 134 statements. While some minor contradiction was demonstrated, strong consensus emerged around the issues of defining health promotion and health education and the emergence of a wider health promotion and health education role for nursing. No consensus was reached on only one of the 13 identified topic categories - that of 'nurses working with other disciplines and agencies in a health education and health promotion role.'

    No effective treatments have been found for flap necrosis. Animal models that focus on the initial flap viability are inappropriate for necrotic wound studies. Keratinocyte growth factor (KGF) promotes keratinocyte proliferation with stronger activity and fewer complications and thus may be useful for necrotic flap wound healing. Rats with modified flap necrosis were randomly divided into four groups. An adenoviral vector expressing KGF was injected subdermally in the back of the animals after necrosis began. The expression and effect of KGF was assessed by real-time polymerase chain reaction, enzyme-linked immunoassay, and transwell, and wound healing was monitored. The plasmid and adenovirus were able to express KGF and stimulate epithelial cell growth (p = 0.029). Histology showed that the necrosis healed fastest in the KGF administration group than in the control groups (p < 0.01). The adenovirus-mediated KGF (Ad-KGF) group had the thickest epithelium on days 15 (p = 0.044) and 25 (p = 0.014). The KGF level in the blood serum soared 10 and 15 days postoperatively (p < 0.01) but returned to baseline by day 25 (p = 0.561). The KGF mRNA levels in vivo increased dramatically in the Ad-KGF group (p = 0.037). The extended flap model is applicable in necrotic wound study. Keratinocyte growth factor can promote secondary necrotic flap wound healing, and administration of KGF can be achieved by an adenoviral vector.

  17. On Promoting the Construction of Model Province of National Rural Informationization in Hubei

    2014-04-01

    Full Text Available The construction of model province of national rural informationization, which needs more departments jointly and participants, is a systematic, socialized major project. Hubei provincial government, standing in the angle of planning the province's economic and social development as a whole, proposes the “one Yuan multi-level” development strategy and it has laid a solid foundation to make Hubei province become the construction pilot provinces of “model province of national rural informationization”. In the construction of model province of rural informationization, the open and inclusive concept is of great significance to realize national long-term goals and make the rural information service sustained and long efficient. At the same time, each department and each participation main body coordinate with each other, which realize the integration of rural information service resources and prevent rural information service from redundant and inefficient investment. Therefore, in the construction of model province of national rural informationization, Hubei province need to uphold the open and inclusive concept, further emancipate the mind, and complement each other. It should strengthen organizational leadership, complete the top planning and design, strengthen the department coordination, innovate information services operating mechanism, strengthen integration of information resources and integrated application of service platform, strengthen the system construction and examination management, strengthen the propaganda guidance, and further promote each work of model province carried out smoothly and orderly.

    2017-11-01

    Scientific reasoning is particularly pertinent to science education since it is closely related to the content and methodologies of science and contributes to scientific literacy. Much of the research in science education investigates the appropriate framework and teaching methods and tools needed to promote students' ability to reason and evaluate in a scientific way. This paper aims (a) to contribute to an extended understanding of the nature and pedagogical importance of model-based reasoning and (b) to exemplify how using computer simulations can support students' model-based reasoning. We provide first a background for both scientific reasoning and computer simulations, based on the relevant philosophical views and the related educational discussion. This background suggests that the model-based framework provides an epistemologically valid and pedagogically appropriate basis for teaching scientific reasoning and for helping students develop sounder reasoning and decision-taking abilities and explains how using computer simulations can foster these abilities. We then provide some examples illustrating the use of computer simulations to support model-based reasoning and evaluation activities in the classroom. The examples reflect the procedure and criteria for evaluating models in science and demonstrate the educational advantages of their application in classroom reasoning activities.

  19. Defining sustainable practice in community-based health promotion: a Delphi study of practitioner perspectives.

    2013-04-01

    Sustainability of practice must be a central imperative in the practice of community-based health promotion to achieve population health and attract a greater share of public health spending. Although there has been some consideration of sustainability at the project or program levels, often understood as intervention longevity, very limited attention has been given to understanding sustainable practice. The present study develops a definition and features of sustainable practice in community-based health promotion through a Delphi method with health promotion practitioners in Queensland, Australia. The study presents a consensus definition and features of sustainable practice. The definition highlights the importance of collaboration, health determinants and aspirations, processes and outcomes. The four features of sustainable practice identified in the study are: (1) effective relationships and partnerships; (2) evidence-based decision making and practice; (3) emphasis on building community capacity; and (4) supportive context for practice. The definition and features are, to a large extent, consistent with the limited literature around sustainability at the project and program levels of health promotion. Together, they provide insight into a form of community-based health promotion that will be both viable and productive. So what? This consensus understanding of sustainable practice articulates the foundations of working effectively with local communities in achieving improved population health within global limits.

  1. Understanding How Domestic Violence Support Services Promote Survivor Well-being: A Conceptual Model.

    Science.gov (United States)

    Sullivan, Cris M

    2018-01-01

    Domestic violence (DV) victim service programs have been increasingly expected by legislators and funders to demonstrate that they are making a significant difference in the lives of those using their services. Alongside this expectation, they are being asked to describe the Theory of Change guiding how they believe their practices lead to positive results for survivors and their children. Having a widely accepted conceptual model is not just potentially useful to funders and policy makers as they help shape policy and practice -- it can also help programs continually reflect upon and improve their work. This paper describes the iterative and collaborative process undertaken to generate a conceptual model describing how DV victim services are expected to improve survivors' lives. The Social and Emotional Well-Being Framework guiding the model is an ideal structure to use to describe the goals and practices of DV programs because this framework: (1) accurately represents DV programs' goal of helping survivors and their children thrive; and (2) recognizes the importance of community, social, and societal context in influencing individuals' social and emotional well-being. The model was designed to guide practice and to generate new questions for research and evaluation that address individual, community, and systems factors that promote or hinder survivor safety and well-being.

    The anaphase-promoting complex (APC/C) is a large E3 ubiquitin ligase that regulates progression through specific stages of the cell cycle by coordinating the ubiquitin-dependent degradation of cell-cycle regulatory proteins. Depending on the species, the active form of the APC/C consists of 14-15 different proteins that assemble into a 20-subunit complex with a mass of approximately 1.3 MDa. A hybrid approach of single-particle electron microscopy and protein crystallography of individual APC/C subunits has been applied to generate pseudo-atomic models of various functional states of the complex. Three approaches for assigning regions of the EM-derived APC/C density map to specific APC/C subunits are described. This information was used to dock atomic models of APC/C subunits, determined either by protein crystallography or homology modelling, to specific regions of the APC/C EM map, allowing the generation of a pseudo-atomic model corresponding to 80% of the entire complex.

  3. Zealotry promotes coexistence in the rock-paper-scissors model of cyclic dominance.

    2015-11-01

    Cyclic dominance models, such as the classic rock-paper-scissors (RPS) game, have found real-world applications in biology, ecology, and sociology. A key quantity of interest in such models is the coexistence time, i.e., the time until at least one population type goes extinct. Much recent research has considered conditions that lengthen coexistence times in an RPS model. A general finding is that coexistence is promoted by localized spatial interactions (low mobility), while extinction is fostered by global interactions (high mobility). That is, there exists a mobility threshold which separates a regime of long coexistence from a regime of rapid collapse of coexistence. The key finding of our paper is that if zealots (i.e., nodes able to defeat others while themselves being immune to defeat) of even a single type exist, then system coexistence time can be significantly prolonged, even in the presence of global interactions. This work thus highlights a crucial determinant of system survival time in cyclic dominance models.

    Opiate dependency is a medical disorder that requires treatment intervention. Primary health care not only entails treatment of illness but also involves disease prevention and health promotion. Based on Pender's revised Health Promotion Model, a descriptive study comparing the health promoting behaviors/practices in abusing and recovering opiate-dependent drug users is analyzed. Using the Health Promoting Lifestyle Profile II, a comparative descriptive, exploratory, nonexperimental design study was conducted to identify key health-promoting behaviors in recovering opiate-dependent drug users. Prevention strategy recommendations are discussed, along with future research recommendations. Copyright © 2013 Elsevier Inc. All rights reserved.

    Research purpose: The study aimed to test moderating effects of promotion and prevention focus within the job demands-resources model in a context of organisational change. Predictors included job demands and resources whilst outcomes included emotional exhaustion, disengagement and openness to change. Motivation for the study: The study intended to understand whether individual differences in promotion and prevention focus play an important role during the experience of organisational change. Research design, approach and method: A sample of 164 teachers from the Netherlands participated in a quantitative survey design before a new governmental policy was implemented in their schools and 189 different teachers working in the same schools participated in the survey after the implementation of the policy. Cross-sectional moderated regression analyses were used to analyse the data. Main findings: Promotion focus moderated the relationship between job demands and openness to change, whilst both promotion and prevention focus moderated many of the relationships between job resources on the one hand and emotional exhaustion, disengagement and openness to change on the other hand. Practical/managerial implications: Knowing that organisational change can have different meanings for promotion and prevention focused employees, managers can facilitate employee adaptation to change. Contribution/value-add: This research provides a theoretical framework that incorporates self-regulation as a moderator in the job demands-resources model. At the same time, implications for organisational change were co-examined.

    Full Text Available Background: One of non pharmacologic strategies influencing diabetes is physical activity which is not easy to change and maintain due to its complexity. The main objective of the present study is to identify the factors which influence physical activities on the basis of health promotion model. Methods: In this study 350 women suffering from diabetes responded to the standard questionnaires related to the perceived self efficacy (belief about capabilities for doing physical activity under different sets of conditions , perceived barrier and benefit, family and friend support and perceived health status constructs. Linear and logistic regressions, t tests, and chi square tests were used to analyze the data. Results: The results of the present study indicated that self efficacy has positive and direct impacts on physical activities and the perceived benefits, the perceived health status, and the body mass index (BMI has indirect impacts on physical activities. Moreover, the perceived health status in addition to the indirect impacts has direct and positive impacts on physical activities and influence by factors such as job and duration of disease. Conclusion: The perceived health status is one of the most influential factors on physical activities of diabetic patients which is necessary to be taken into consideration especially for patients with long term disease. It is also urgent that through increasing self efficacy with using different techniques and emphasizing different aspects of physical activity benefits, resulted to promote the activity level of the patients.

    A cluster random sample of 1073 students in the Islamic Republic of Iran (mean age 14.37 years) completed a self-report questionnaire consisting of an exercise measure, selected constructs of Pender's health promotion model and an assessment of stages of behaviour change in exercise. In multivariate discriminant analysis, exercise self-efficacy, perceived barriers to exercise, perceived benefits of exercise and exercise behaviour were significant predictors of the stage of exercise behaviour change for both female and male adolescents. The findings support the importance of self-efficacy for engaging in physical activity for both sexes of Iranian adolescents. The barriers faced by Iranian girls should be considered in interventions to increase physical activity rates.

    2016-12-01

    The present study investigated the effects of myo-inositol on muscle glucose uptake and intestinal glucose absorption ex vivo as well as in normal and type 2 diabetes model of rats. In ex vivo study, both intestinal glucose absorption and muscle glucose uptake were studied in isolated rat jejunum and psoas muscle respectively in the presence of increasing concentrations (2.5 % to 20 %) of myo-inositol. In the in vivo study, the effect of a single bolus dose (1 g/kg bw) of oral myo-inositol on intestinal glucose absorption, blood glucose, gastric emptying and digesta transit was investigated in normal and type 2 diabetic rats after 1 h of co-administration with 2 g/kg bw glucose, when phenol red was used as a recovery marker. Myo-inositol inhibited intestinal glucose absorption (IC 50  = 28.23 ± 6.01 %) and increased muscle glucose uptake, with (GU 50  = 2.68 ± 0.75 %) or without (GU 50  = 8.61 ± 0.55 %) insulin. Additionally, oral myo-inositol not only inhibited duodenal glucose absorption and reduced blood glucose increase, but also delayed gastric emptying and accelerated digesta transit in both normal and diabetic animals. Results of this study suggest that dietary myo-inositol inhibits intestinal glucose absorption both in ex vivo and in normal or diabetic rats and also promotes muscle glucose uptake in ex vivo condition. Hence, myo-inositol may be further investigated as a possible anti-hyperglycaemic dietary supplement for diabetic foods and food products.

    Absorption of carbon dioxide (CO2) using potassium carbonate (K2CO3) is one of biogas purification method. However, K2CO3 have slow mass transfer in liquid phase. So it is necessary to eliminate the disadvantage of CO2 absorption using K2CO3 by adding promotor (activator). Diethanol amine (DEA) is one of promotor which can increase its reaction rate. Simulation and modeling research of the CO2 absorption from biogas with DEA promoted K2CO3 solution has not been conducted. Thus, the main goal of this research is create model and simulation for the CO2 absorption from biogas with DEA promoted K2CO3 solution, then observe the influence of promoter concentration. DEA concentration varies between 1-5 %wt. From the simulation, we concluded that the CO2 removal rise with the increasing of promoter concentration. The highest CO2 removal is 54.5318 % at 5 % wt DEA concentration.

    Full Text Available Model Forests are partnerships for shared decision-making to support social, environmental, and economic sustainability in forest management. Relationships among sustainable forest management partners are often strained, but the Prince Albert Model Forest (PAMF represents a process of effective stakeholder involvement, cooperative relationships, visionary planning, and regional landscape management. This article seeks to critically examine the history, drivers, accomplishments, and challenges associated with the PAMF. Four key phases are discussed, representing different funding levels, planning processes, research projects, and partners. Key drivers in the PAMF were funding, urgent issues, provincial responsibility, core of committed people, evolving governance, desire for a neutral organisation, role of protected areas, and potential for mutual benefits. The stakeholders involved in the Model Forest, including the forest industry and associated groups, protected areas, Aboriginal groups, local communities, governments, and research groups, were committed to the project, cooperated on many joint activities, provided significant staffing and financial resources, and gained many benefits to their own organisations. Challenges included declining funding, changing administrative structures, multiple partners, and rotating representatives. The PAMF process promoted consultative and integrated land resource management in the region, and demonstrated the positive results of cooperation between stakeholders interested in sustainable forest management.

    Peripheral nerve injury is one of common traumas. Although injured peripheral nerves have the capacity to regenerate, axon regeneration proceeds slowly and functional outcomes are often poor. Pharmacological enhancement of regeneration can play an important role in increasing functional recovery. In this study, we developed a novel electrospun nanofiber sheet incorporating methylcobalamin (MeCbl), one of the active forms of vitamin B12 homologues, to deliver it enough locally to the peripheral nerve injury site. We evaluated whether local administration of MeCbl at the nerve injury site was effective in promoting nerve regeneration. Electrospun nanofiber sheets gradually released MeCbl for at least 8weeks when tested in vitro. There was no adverse effect of nanofiber sheets on function in vivo of the peripheral nervous system. Local implantation of nanofiber sheets incorporating MeCbl contributed to the recovery of the motor and sensory function, the recovery of nerve conduction velocity, and the promotion of myelination after sciatic nerve injury, without affecting plasma concentration of MeCbl. Methylcobalamin (MeCbl) is a vitamin B12 analog and we previously reported its effectiveness in axonal outgrowth of neurons and differentiation of Schwann cells both in vitro and in vivo. Here we estimated the effect of local administered MeCbl with an electrospun nanofiber sheet on peripheral nerve injury. Local administration of MeCbl promoted functional recovery in a rat sciatic nerve crush injury model. These sheets are useful for nerve injury in continuity differently from artificial nerve conduits, which are useful only for nerve defects. We believe that the findings of this study are relevant to the scope of your journal and will be of interest to its readership. Copyright © 2017 Acta Materialia Inc. Published by Elsevier Ltd.

    Health promotion constitutes a complex field of study, as it addresses multifaceted problems and involves a range of methods and theories. Students in the field of health promotion can find this challenging. To raise their level of reflexivity and support learning we have developed the “context...... model,” which is presented in this article. The model provides a framework for the analysis of health-promotion initiatives, employing eight perspectives each intertwined with the others. It is based on the assumption that health and health inequities are contextual and that the theoretically inspired...... understanding of contexts is central for health promoters. Contexts for health are seen as more than the local setting; they are embedded in societal and global conditions—which, vice versa, influence the local setting. A Danish community health project is used to exemplify how the model can be used in relation...

    Full Text Available Background: Changes in lifestyle and eating habits have put women at risk of obesity and overweight more than ever. This aim of this study was to investigate the effect of Pender’s Health Promotion Model (HPM to improve the nutritional behavior of overweight and obese women admitted to Fatemiyeh Hospital clinics in Hamadan, west Iran in 2015. Methods: n this quasi-experimental study, 108 eligible women were selected and randomly assigned to two groups: one experimental and one control. Data were gathered using three questionnaires: demographics, Pender’s HPM constructs, and nutritional behavior. The questionnaires were filled out by both groups as pre-test and two months later. A Pender’s HPM-based intervention was conducted for the experimental group. The data were analyzed by paired and independent t-tests, ANCOVA, and Spearmans’ correlation coefficient in SPSS/16. The level of significance was considered to be <0.05. Results: The mean score of nutritional behavior was 41.75±3.28 and 42.36±3.69 before the intervention and 79.09±5.27 and 49.72±9.49 after it in the experimental and control groups, respectively. The difference was significant only between before and after the intervention in the experimental group (P<0.001. Furthermore, the mean scores of the following variables were significantly different between before and after the intervention in the experimental group: nutritional behavior, perceived benefits, perceived self-efficacy, commitment to action, interpersonal and situational influences, behavior-related affect, and perceived barriers (P<0.001. Conclusion: The results showed that Pender’s HPM-based training improved nutritional behavior and some constructs of the model. Therefore, this educative model can be used by healthcare providers to improve the nutritional and other health promoting behaviors.

    The purpose of this study is to identify the associations between self-efficacy and the various factors in the Health Belief Model (HBM), and the health-promoting behaviors of people with, or at high risk of, Metabolic Syndrome (MS). 132 adults with two or more MS components were included in this cross-sectional study. Health-promoting behavior, self-efficacy and the four-constructs of HBM (perceived threat, cues, benefits, and barriers) were measured using validated tools. The contributions of each HBM factor towards the respective behavior were identified using a three-step hierarchical regression approach. After controlling for age, gender, education level, income and knowledge of MS, HBM factors accounted for 11% of the total variance in health-promoting behaviors. Beliefs about barriers were found to be a significant predictor of exercise (β=-.28, phealth-promoting behaviors. In the final model, self-efficacy explained an additional 31% of the variance in exercise behavior and 13% in diet management behavior. Self-efficacy and perceived barriers made independent contributions to health-promoting behavior among people with, or at high risk of, MS. Community health program targeting this particular group should tailor strategies that can enhance individuals' self-efficacy and address barriers perceived. Copyright © 2014 Elsevier Inc.

    The aim of this study was to describe dialogic strategies about health and lifestyle used by primary healthcare nurses (PHNs) in the Västerbotten Intervention Programme (VIP) in Sweden. The VIP offers all citizens aged 40, 50 and 60 in Västerbotten County an individual health check-up followed by a health-promoting dialogue with a specialist PHN. Inconsistencies in previous reports of the effects of lifestyle counselling and health promotion suggest that it is important to study dialogues about health and lifestyle to understand health-promoting strategies and to highlight aspects important to improving their effects. In 2010, we conducted in-depth interviews with ten experienced PHNs working with the VIP at eight healthcare centres in Västerbotten County, Sweden. Qualitative content analysis was used to illuminate the nurses' strategies in health-promoting dialogues. The Regional Ethics Board (Dno 06-126M) approved the study. The PHNs used various strategies in dialogues about health and lifestyle that fell under the five themes 'Guiding patients vs. pressuring them; Adjusting to patients vs. directing the conversation; Inspiring confidence vs. instilling fear; Motivating and supporting patients vs. demanding responsibility; and lastly, Introducing emotionally charged subjects or avoiding them'. The results of this study may add knowledge about the difficulties and opportunities in health counselling. In the discussion, we suggest professional reflection as a means to increase knowledge and awareness about the self and context in the process of health counselling. © 2013 Nordic College of Caring Science.

    Full Text Available Abstract Background General practice staff are reluctant to discuss sexual health opportunistically in all consultations. Health promotion materials may help alleviate this barrier. Chlamydia screening promotion posters and leaflets, produced by the English National Chlamydia Screening Programme (NCSP, have been available to general practices, through local chlamydia screening offices, since its launch. In this study we explored the attitudes of general practice staff to these screening promotional materials, how they used them, and explored other promotional strategies to encourage chlamydia screening. Methods Twenty-five general practices with a range of screening rates, were purposively selected from six NCSP areas in England. In focus groups doctors, nurses, administrative staff and receptionists were encouraged to discuss candidly their experiences about their use and opinions of posters, leaflets and advertising to promote chlamydia screening. Researchers observed whether posters and leaflets were on display in reception and/or waiting areas. Data were collected and analysed concurrently using a stepwise framework analytical approach. Results Although two-thirds of screening practices reported that they displayed posters and leaflets, they were not prominently displayed in most practices. Only a minority of practices reported actively using screening promotional materials on an ongoing basis. Most staff in all practices were not following up the advertising in posters and leaflets by routinely offering opportunistic screening to their target population. Some staff in many practices thought posters and leaflets would cause offence or embarrassment to their patients. Distribution of chlamydia leaflets by receptionists was thought to be inappropriate by some practices, as they thought patients would be offended when being offered a leaflet in a public area. Practice staff suggested the development of pocket-sized leaflets. Conclusion The NCSP

    Full Text Available The "Agita São Paulo" Program applies a multilevel intervention approach to promoting physical activity among the 37 million inhabitants of the state of São Paulo, Brazil. The verb "agita" means to move the body, but the term also suggests changing the way of thinking and becoming a more active citizen. Since being launched in 1996, the Program has been widely copied throughout Brazil and in other countries of Latin America, and the World Health Organization has characterized it as a model for other developing countries. The Program aims to disseminate a clear and simple message to the community as well as establish partnerships with governmental and nongovernmental organizations and other entities. The Agita São Paulo message encourages people to adopt an active lifestyle by accumulating at least 30 minutes of moderate physical activity per day, on most days of the week. The Program has three main target groups: students, workers, and the elderly. The Program organizes "mega-events" that simultaneously reach and involve large numbers of people, and it also conducts ongoing activities with institutions that become partners of the Program. Intervention studies that the Program has carried out on specific, small groups have found both changes in behavior and an increasing awareness of the Program's name and message. In addition, surveys have found that a growing number of persons in the state of São Paulo have become aware of the Program and its message and have changed their physical activity level. A number of the special features of and lessons learned from the Agita São Paulo Program may have contributed to its success, including: a multisectorial approach; broad use of partnerships; the inclusion principle (avoiding messages or attitudes that might exclude any social group; the scientific basis for all the Program activities; the extensive free media coverage that the Program has received; a "two-hats" approach, using either governmental

    Full Text Available There is a large number of studies on how to promote students’ cognitive processes and learning achievements through various learning activities supported by advanced learning technologies. However, not many of them focus on applying the knowledge that students learn in school to solve authentic daily life problems. This study aims to propose a cognitive diffusion model called User-oriented Context-to-Text Recognition for Learning (U-CTRL to facilitate and improve students’ learning and cognitive processes from lower levels (i.e., Remember and Understand to higher levels (i.e., Apply and above through an innovative approach, called User-Oriented Context-to-Text Recognition for Learning (U-CTRL. With U-CTRL, students participate in learning activities in which they capture the learning context that can be scanned and recognized by a computer application as text. Furthermore, this study proposes the use of an innovative model, called Cognitive Diffusion Model, to investigate the diffusion and transition of students’ cognitive processes in different learning stages including pre-schooling, after-schooling, crossing the chasm, and higher cognitive processing. Finally, two cases are presented to demonstrate how the U-CTRL approach can be used to facilitate student cognition in their learning of English and Natural science.

    Health promotion programs are commonly viewed as value-free initiatives which seek to improve health, often through behavior change. An opposing view has begun to emerge that health promotion efforts, especially ones seeking to impact health policy and social determinants of health, are vulnerable to political contexts and may depend on who is in power at the time. This community-based participatory research study attempts to understand these interactions by applying a conceptual model focused on the power context, diverse stakeholder roles within this context, and the relationship of political levers and other change strategies to the sustainability of health promotion interventions aimed at health policy change. We present a case study of a health promotion coalition, New Mexico for Responsible Sex Education (NMRSE), as an example of power dynamics and change processes. Formed in 2005 in response to federal policies mandating abstinence-only education, NMRSE includes community activists, health promotion staff from the New Mexico Department of Health, and policy-maker allies. Applying an adapted Mayer's 'power analysis' instrument, we conducted semi-structured stakeholder interviews and triangulated political-context analyses from the perspective of the stakeholders.We identified multiple understandings of sustainability and health promotion policy change, including: the importance of diverse stakeholders working together in coalition and social networks; their distinct positions of power within their political contexts; the role of science versus advocacy in change processes; the particular challenges for public sector health promotion professionals; and other facilitators versus barriers to action. One problem that emerged consisted of the challenges for state employees to engage in health promotion advocacy due to limitations imposed on their activities by state and federal policies. This investigation's results include a refined conceptual model, a power

    Full Text Available Background: Primary care is increasingly being encouraged to integrate healthy lifestyle promotion in routine care. However, implementation has been suboptimal. Coordinated care could facilitate lifestyle promotion practice but more empirical knowledge is needed about the implementation process of coordinated care initiatives. This study aimed to evaluate the implementation of a coordinated healthy lifestyle promotion initiative in a primary care setting.Methods: A mixed method, convergent, parallel design was used. Three primary care centres took part in a two-year research project. Data collection methods included individual interviews, document data and questionnaires. The General Theory of Implementation was used as a framework in the analysis to integrate the data sources.Results: Multi-disciplinary teams were implemented in the centres although the role of the teams as a resource for coordinated lifestyle promotion was not fully embedded at the centres. Embedding of the teams was challenged by differences among the staff, patients and team members on resources, commitment, social norms and roles.Conclusions: The study highlights the importance of identifying and engaging key stakeholders early in an implementation process. The findings showed how the development phase influenced the implementation and embedding processes, which add aspects to the General Theory of Implementation.

    Full Text Available Estrogen induces oligodendrocyte remyelination in response to demyelination in the central nervous system. Our objective was to determine the effects of 17β-estradiol (E2 on Schwann cell function and peripheral nerve remyelination after injury. Adult male C57BL/6J mice were used to prepare the sciatic nerve transection injury model and were randomly categorized into control and E2 groups. To study myelination in vitro, dorsal root ganglion (DRG explant culture was prepared using 13.5-day-old mouse embryos. Primary Schwann cells were isolated from the sciatic nerves of 1- to 3-day-old Sprague–Dawley rats. Immunostaining for myelin basic protein (MBP expression and toluidine blue staining for myelin sheaths demonstrated that E2 treatment accelerates early remyelination in the “nerve bridge” region between the proximal and distal stumps of the transection injury site in the mouse sciatic nerve. The 5-bromo-2′-deoxyuridine incorporation assay revealed that E2 promotes Schwann cell proliferation in the bridge region and in the primary culture, which is blocked using AKT inhibitor MK2206. The in vitro myelination in the DRG explant culture determined showed that the MBP expression in the E2-treated group is higher than that in the control group. These results show that E2 promotes Schwann cell proliferation and myelination depending on AKT activation.

    This paper reports on a study of the absenteeism experience of two groups of Johnson & Johnson employees over a 3-year period. Employees at four company sites (n = 1406) where LIVE FOR LIFE, a comprehensive health promotion program, had been introduced, were compared with employees at five company sites (n = 487) without the health promotion program. Analyses of covariance were employed to control for differences between the two study groups with respect to age, gender, job classification (wage or salaried), as well as baseline levels of absenteeism. Adjusted mean levels of absenteeism among wage earners in the LIVE FOR LIFE groups were found to decline over the study period, and were significantly lower (P less than .01) than mean levels for the non-LIVE FOR LIFE wage employees in the final year of the study. No significant differences were found for salaried personnel.

    Promoting neurogenesis is a promising strategy for the treatment of cognition impairment associated with Alzheimer's disease (AD). Ganoderma lucidum is a revered medicinal mushroom for health-promoting benefits in the Orient. Here, we found that oral administration of the polysaccharides and water extract from G. lucidum promoted neural progenitor cell (NPC) proliferation to enhance neurogenesis and alleviated cognitive deficits in transgenic AD mice. G. lucidum polysaccharides (GLP) also promoted self-renewal of NPC in cell culture. Further mechanistic study revealed that GLP potentiated activation of fibroblast growth factor receptor 1 (FGFR1) and downstream extracellular signal-regulated kinase (ERK) and AKT cascades. Consistently, inhibition of FGFR1 effectively blocked the GLP-promoted NPC proliferation and activation of the downstream cascades. Our findings suggest that GLP could serve as a regenerative therapeutic agent for the treatment of cognitive decline associated with neurodegenerative diseases. Copyright © 2017 The Authors.

    The polyhedrin gene promoter has an essential role in regulating foreign gene expression in baculovirus expression vector systems (BEVS); however, the high-level transcription mechanism is still unknown. One-hybrid screening in yeast is a powerful way of identifying rapidly heterologous transcription factors that can interact with the polyhedrin promoter DNA sequence. In the current study, total RNA was extracted from the fat bodies of fifth-instar silkworm larvae that had been infected with Bombyx mori nuclear polyhedrosis virus (BmNPV) for 5 days; complementary DNA (cDNA) was then generated using reverse-transcription (RT)-PCR to construct a silkworm gene expression library. Key polyhedrin promoter bait sequences were synthesized to generate a bait yeast strain, which was used to screen the one-hybrid cDNA library. In total, 12 positive yeast colonies were obtained from the SD/-Leu/AbA plates; sequencing analysis showed that they belong to two different protein cDNA colonies. Positive colonies underwent bioinformatics analysis, which revealed one colony to be ribosomal proteins [B. mori ribosomal protein SA (BmRPSA)] and the other to be NPV DNA-binding proteins (DBP). To further verify the regulatory function of these two protein groups, transient expression vectors (pSK-IE-dbp and pSK-IE-BmRPSA) were constructed. The recombinant plasmids were then transfected into cultured B. mori N (BmN) cells, which had been infected with a recombinant bacmid containing the gene encoding luciferase (luc). The results showed that overexpression of either dbp or BmRPSA upregulated the polh promoter-driven transcription of luc in BmN cells. In addition, dbp or BmRPSA RNA interference (RNAi) resulted in the downregulation of luciferase reporter expression in BmN cells, demonstrating that DBP and BmRPSA are important for luc transcription. EMSA results further confirmed that DBP could directly bind to the conserved single-stranded polh promoter region in intro. However, EMSA

    Full Text Available Introduction & Objective: Participation in regular physical activity is associated with a variety of positive outcomes for young people. Physical activity (PA rates decline precipitously during the high school years and are consistently lower among adolescent girls than among adolescent boys. In order to stop or diverse this negative trend, there are necessary interventions based on various theories and models to promote physical activity in girls. Materials & Methods: This randomized control study evaluated the effectiveness of a 24-week exercise education program based on Pender’s Health Promotion model to improve cognitive and psychosocial factors associated with physical activity and to promote physical activity in adolescent girls (n =106. The program included educational sessions and tailored counseling. Results: There was an increase of 45 minutes for daily physical activity in the experimental group compared to their baseline. After intervention, the training group had a positive significant progression in stages along with significant improvements in self efficacy, enjoyment of physical activity, interpersonal influences, planning for physical activity, and also a decrease in perceived barriers to physical activity and competing preferences (p ≤ .0001-0.04. Conclusion: Findings of this study showed the positive effect of program on stage of change and potential determinants of the behavior of physical activity. The high proportion of the people in action and maintenance in experimental group compared to the baseline and the attainment of recommend criteria for physical activity are promising findings of school-based intervention based on Pender’s health promotion model.

    Full Text Available Abstract Background The number of chronically ill patients increases every year. This is partly due to an unhealthy lifestyle. However, the frequency and quality of (evidence-based health promotion activities conducted by Dutch general practitioners (GPs and practice nurses (PNs are limited. The aim of this pilot study was to explore which lifestyle interventions Dutch GPs and PNs carry out in primary care, which barriers and facilitators can be identified and what main topics are with respect to attitudes towards health promoting activities. These topic areas will be identified for a future, larger scale study. Method This qualitative study consisted of 25 semi-structured interviews with sixteen GPs and nine PNs. ATLAS.ti was used to analyse the transcripts of the interviews. Results All GPs and PNs said they discuss lifestyle with their patients. Next to this, GPs and PNs counsel patients, and/or refer them to other disciplines. Only few said they refer patients to specific lifestyle programs or interventions in their own practice or in the neighbourhood. Several barriers and facilitators were identified. The main topics as barriers are: a lack of patients’ motivation to make lifestyle changes, insufficient reimbursement, a lack of proven effectiveness of interventions and a lack of overview of health promoting programs in their neighbourhood. The most cited facilitators are availability of a PN, collaboration with other disciplines and availability of interventions in their own practice. With respect to attitudes, six different types of GPs were identified reflecting the main topics that relate to attitudes, varying from ‘ignorer’ to ‘nurturer’. The topics relating to PNs attitudes towards health promotion activities, were almost unanimously positive. Conclusion GPs and PNs all say they discuss lifestyle issues with their patients, but the health promotion activities that are organized in their practice vary. Main topics that hinder

    Full Text Available This research aims to investigate the history of secondary school student councils in North-eastern Thailand (Isan, to study the present conditions and problems of secondary school student councils in Isan and to study a model for promoting democracy by using the corporate culture of secondary school student councils in Isan. The study area encompassed Kalasin Province, including Somdetpittayakom School in Somdet District and Yangtaladwittayakarn School in Yangtalat District, Mahasarakham Province, including Sarakhampittayakhom School in Muang District and Kantarawichai School in Kantarawichai District, and Khon Kaen Province, including Kallayanawat School in Muang District and Nampong Suksa School in Nampong District. This research employed interview, observation and focus groups as data collection tools with a purposive sample of student councils in secondary schools in Isan. Data was verified and validated using a triangulation method and analyzed by descriptive analysis. Research results show that the student councils in the secondary schools of Isan were established to promote democracy among youth. Students gained knowledge, understanding of the democratic system, experience in student administration and governance by students for students. It was also found that student council activities in secondary schools give students opportunities to know about their roles, acceptance, respect rights and duties, use intellect to solve problems, have faith in the democratic system, develop morality and ethics and preserve and disseminate traditions and culture according to the principles of Dharma. Current problems with student councils include no student interest in duties and no relationship between the elected leaders and their constituency. Selfishness, dishonesty and ignorance are the causes of non-transparent school councils with no responsibility, no response to student needs, lack of rights, justice and effectiveness, lacking of creative

    2016-11-01

    The structural and physiologic changes in a woman's body during pregnancy can predispose pregnant women to low back pain and its associated disability, as well as to complications of pregnancy, labor, and delivery. Anecdotal and empirical evidence has indicated that osteopathic manipulative treatment (OMT) may be efficacious in improving pain and functionality in women who are pregnant. Based on that premise, the Pregnancy Research on Osteopathic Manipulation Optimizing Treatment Effects (PROMOTE) study was designed as a prospective, randomized, placebo-controlled, and blinded clinical trial to evaluate the efficacy of an OMT protocol for pain during third-trimester pregnancy. The OMT protocol developed for the PROMOTE study was based on physiologic theory and the concept of the interrelationship of structure and function. The 12 well-defined, standardized OMT techniques used in the protocol are commonly taught at osteopathic medical schools in the United States. These techniques can be easily replicated as a 20-minute protocol applied in conjunction with usual prenatal care, thus making it feasible to implement into clinical practice. This article presents an overview of the study design and treatment protocols used in the PROMOTE study.

    In Southeast Asia, hundreds of thousands of young rural women migrate from their villages to the larger cities in search of work. Many find employment with beer companies or in the clubs where beer is sold, promoting the sale of beer. Previous research suggests these young migrants are in a highly vulnerable position. This paper will describe the findings of an October 2009 meeting to develop a research agenda on the sexual and reproductive health of beer promoters and a subsequent pilot study of focus groups with beer promoters to review this agenda. Participants of the research meeting representing beer promoters, academics, non-governmental organizations (NGOs), government and the beer industry from Cambodia, Thailand, Laos, and Vietnam collaborated in the development of three key research themes. The themes were verified in focus group discussions with beer promoters organized by local research partners in all four countries. The focus group participants were asked what they felt were the key sexual and reproductive health issues facing them in a non-directive and unstructured manner, and then asked to comment more specifically on the research priorities developed at the meeting. The focus groups were recorded digitally, transcribed, and translated into English. The data were analyzed by coding for common themes and then developing matrices to compare themes between groups. The participants of the meeting identified three key research themes: occupational health (including harassment and violence, working conditions, and fair pay), gender and social norms (focusing on the impact of power relations between the genders on women's health), and reproductive health (knowledge and access to reproductive health care services). The participants in the focus groups in all four countries agreed that these were key priorities for them, though the emphasis on the most important issues varied between groups of women.

The focus groups were recorded digitally, transcribed, and translated into English. The data were analyzed by coding for common themes and then developing matrices to compare themes between groups. Results The participants of the meeting identified three key research themes: occupational health (including harassment and violence, working conditions, and fair pay, gender and social norms (focusing on the impact of power relations between the genders on women's health, and reproductive health (knowledge and access to reproductive health care services. The participants in the focus groups in all four countries agreed that these were key priorities for them, though the emphasis on the most important issues varied between groups of women

    The distinct process of megakaryopoiesis requires occurrence of endomitosis for polyploidization of the megakaryocytes. Although, Cyclins, CDKs and have been described to regulate endomitosis, the exact mechanism still remains an enigma. miRNA which were otherwise known as post transcriptional gene silencers are now emerging with various non-canonical functions including gene regulation at pre-transcriptional level by miRNA binding at promoter region. Out of the many processes they regulate, miRNA have been manifested to play a role in megakaryocyte differentiation. In this study an attempt has been made to identify miRNA that could regulate cell cycle genes (Cyclins and CDKs) by targeting their promoters, during megakaryopoiesis. A new computational algorithm was implemented using Perl programming to identify putative targets of miRNA in CDK and Cyclin promoters. Perl script was also used to check nuclear localizing miRNA based on the presence of a consensus sequence. Real-time PCR was performed to analyze the expression of miRNA and their predicted targets in Dami vs. PMA treated Dami cells. Putative targets of miRNAs with longest, high complementarity matches in CDK/Cyclin promoters were obtained. We identified two significant miRNA, miR-1273g-3p and miR-619-5p with longest seed sequence matches. We further identified three main targets (CDK10, CDK11, Cyclin F) through which these two miRNA could regulate cell cycle during megakaryopoiesis. Our results reinforce the role of promoting targeting miRNA in regulation of cell cycle through certain CDK/Cyclins to support the process of endomitosis during megakaryopoiesis.

    Whether γ-IR-induced invasion and metastasis are stimulated in our in vitro C6L cell line and in vivo systems, and further identify the associated changes in signal pathways or mice physiology. We constructed an animal model system with a view to clarifying the intracellular molecular events underlying the promotion of metastasis after γ-IR treatment for primary cancer and developing effective anti-metastatic reagents. Our results demonstrate that γ-IR treatment of cancer cell lines and mice xenografts triggers invasion and metastasis. In particular, γ-IR-treated cancer cells or mouse xenografts and metastatic lesions in mice bearing γ-IR-treated xenografts also display typical EMT marker expression patterns, such as increased venetum or MMP-2 expression, decreased E-chondron, and enhanced activity of MMP-2. Our results collectively suggest that γ-IR-induced invasion or metastasis results from induction of EMT, and inhibition of EMT may thus be a means to enhance the effectiveness of radiation therapy. Our results also suggested EMT might be one of the major therapeutic targets to block metastasis.

    Duchenne muscular dystrophy (DMD) is a lethal muscle disease involving progressive loss of muscle regenerative capacity and increased fibrosis. We tested whether epigenetic silencing of the klotho gene occurs in the mdx mouse model of DMD and whether klotho silencing is an important feature of the disease. Our findings show that klotho undergoes muscle-specific silencing at the acute onset of mdx pathology. Klotho experiences increased methylation of CpG sites in its promoter region, which is associated with gene silencing, and increases in a repressive histone mark, H3K9me2. Expression of a klotho transgene in mdx mice restored their longevity, reduced muscle wasting, improved function and greatly increased the pool of muscle-resident stem cells required for regeneration. Reductions of fibrosis in late, progressive stages of the mdx pathology achieved by transgene expression were paralleled by reduced expression of Wnt target genes (axin-2), transforming growth factor-beta (TGF-β1) and collagens types 1 and 3, indicating that Klotho inhibition of the profibrotic Wnt/TGFβ axis underlies its anti-fibrotic effect in aging, dystrophic muscle. Thus, epigenetic silencing of klotho during muscular dystrophy contributes substantially to lost regenerative capacity and increased fibrosis of dystrophic muscle during late progressive stages of the disease.

    Full Text Available The purpose of this study was to determine and understand the predicting factors of a health-promoting lifestyle (HPL in Southeast Asian women in Taiwan. One hundred and five Southeast Asian women in Tainan were recruited. Face-to-face interviews with structured questionnaires were used for data collection. The findings showed that, among the six dimensions of HPL, subjects scored highest in self-actualization and lowest in health responsibility. Subjects who could read and write Chinese had a more positive HPL; stepwise regression analysis revealed that the ability to read Chinese could explain 26.2% of the total variance of HPL in Southeast Asian women. The results of this study can help health care professionals understand the HPL and to design appropriate health-promoting educational programs to improve the well-being and overall quality of life of Southeast Asian women in Taiwan.

    Cambodians living in the U.S.A. suffer from depression, posttraumatic stress disorder (PTSD), and chronic medical disease at rates far in excess of national averages. The Harvard Program in Refugee Trauma's Cambodian Health Promotion Program seeks to address this burden of disease by offering them culturally tailored health education in a group setting. A health professional and a bicultural health educator co-facilitated a five-session health promotion group for Cambodian survivors of torture from 2007 to 2011. The program covered five major topics from Western and Cambodian worldviews. They included the meaning of health promotion, nutrition, exercise, stress management and sleep hygiene, and health practitioner-patient communication. The bicultural worker administered Pre and Post semi-structured Health Promotion Questionnaires. The data presented here are the results from 126 participants. Changes between the Pre and Post health promotion groups demonstrated significant improvements in health status, lifestyle activities, sleep, and depression. Participants revealed greater confidence in communicating with their primary health care practitioner. Culturally tailored Cambodian health promotion education administered in a small group setting may improve health and mental health behaviors. Culturally tailored health promotion education in a small group setting may promote healing in survivors of torture. It is an intervention worthy of further research and development.

    β-Catenin, the transducer of Wnt signaling, is critical for the development and growth of hair follicles. In the absence of Wnt signals, cytoplasmic β-catenin is phosphorylated by glycogen synthase kinase (GSK)-3 and then degraded. Therefore, inhibition of GSK-3 may enhance hair growth via β-catenin stabilization. Valproic acid is an anticonvulsant and a mood-stabilizing drug that has been used for decades. Recently, valproic acid was reported to inhibit GSK-3β in neuronal cells, but its effect on human hair follicles remains unknown. To determine the effect of VPA on human hair growth. We investigated the effect of VPA on cultured human dermal papilla cells and outer root sheath cells and on an in vitro culture of human hair follicles, which were obtained from scalp skin samples of healthy volunteers. Anagen induction by valproic acid was evaluated using C57BL/6 mice model. Valproic acid not only enhanced the viability of human dermal papilla cells and outer root sheath cells but also promoted elongation of the hair shaft and reduced catagen transition of human hair follicles in organ culture model. Valproic acid treatment of human dermal papilla cells led to increased β-catenin levels and nuclear accumulation and inhibition of GSK-3β by phosphorylation. In addition, valproic acid treatment accelerated the induction of anagen hair in 7-week-old female C57BL/6 mice. Valproic acid enhanced human hair growth by increasing β-catenin and therefore may serve as an alternative therapeutic option for alopecia.

    The global organ shortage is the strongest factor for the increase in transplant wait time and deaths on waitlists. Here we describe a model for involving high school students in education research around organ donation and transplantation and capitalize on the strength of a pre-existing educational program offered by the local organ procurement organization (OPO). While training in education research at Cleveland Clinic, a high school student embarked on a collaborative project with the local OPO. The project involved evaluating three educational programs, selecting the most appropriate program for administration at her school, coordinating with the student's school administration and teachers, administering an assessment tool for the effectiveness of the program, and analyzing the results. The local OPO program that was selected for implementation consisted of a video presentation entitled "Share your life, share your decision" prepared by the United States Health Resources and Services Administration (HRSA), lectures by invited speakers and an educational assessment (pre- and post-education). The assessment survey included 3 multiple choice and 7 true/false questions. Compared to the over 2500 programs administered in the last 5 years by the local OPO, this program had a higher volume of participation (n = 353 compared to an average of 150 students/day). Students correctly classified transplantation status of more organ and tissues post-education (P education (P ≤ .002 for all). This experience included for the first time a formal assessment of the program which will be utilized to address targeted areas for specific improvements. This student collaborative model of involving students in organ donation and transplantation related education research has the potential to promote and maximize the effectiveness of educational programs targeting their peers.

    Full Text Available Inactivity and an unhealthy diet amongst others have led to an increased prevalence of overweight and obesity even in young children. Since most health behaviours develop during childhood health promotion has to start early. The setting kindergarten has been shown as ideal for such interventions. “Join the Healthy Boat” is a kindergarten-based health promotion programme with a cluster-randomised study focussing on increased physical activity, reduced screen media use, and sugar-sweetened beverages, as well as a higher fruit and vegetable intake. Intervention and materials were developed using Bartholomew’s Intervention Mapping approach considering Bandura’s social-cognitive theory and Bronfenbrenner’s ecological framework for human development. The programme is distributed using a train-the-trainer approach and currently implemented in 618 kindergartens. The effectiveness of this one-year intervention with an intervention and a control group will be examined in 62 kindergartens using standardised protocols, materials, and tools for outcome and process evaluation. A sample of 1021 children and their parents provided consent and participated in the intervention. Results of this study are awaited to give a better understanding of health behaviours in early childhood and to identify strategies for effective health promotion. The current paper describes development and design of the intervention and its implementation and planned evaluation. Trial Registration. The study is registered at the German Clinical Trials Register (DRKS, Freiburg University, Germany, ID: DRKS00010089.

    This study explores the potential of promoting college students’ positive psychological development using popular online social networks. Online social networks have dramatically changed the ways college students manage their social relationships. Social network activities, such as checking Facebook posts dominates students’ Internet time and has the potential to assist students’ positive development. Positive psychology is a scientific study of how ordinary individuals can apply their strength effectively when facing objective difficulties and how this capability can be cultivated with certain approaches. A positive message delivery approach was designed for a group of new college entrants. A series of positive messages was edited by university counselors and delivered by students to their Facebook social groups. Responses from each posted positive messages were collected and analyzed by researchers. The responses indicated that: (1) relationships of individual engagement and social influence in this study can partially explain the observed student behavior; (2) using class-based social groups can promote a positive atmosphere to enhance strong-tie relationships in both the physical and virtual environments, and (3) promoting student’s positive attitudes can substantially impact adolescents’ future developments, and many positive attitudes can be cultivated by emotional events and social influence.

    Full Text Available Abstract Background This protocol is for a study of a new program to improve outcomes in children suffering from chronic pain disorders, such as fibromyalgia, recurrent headache, or recurrent abdominal pain. Although teaching active pain self-management skills through cognitive-behavioral therapy (CBT or a complementary program such as hypnotherapy or yoga has been shown to improve pain and functioning, children with low expectations of skill-building programs may lack motivation to comply with therapists' recommendations. This study will develop and test a new manualized peer-mentorship program which will provide modeling and reinforcement by peers to other adolescents with chronic pain (the mentored participants. The mentorship program will encourage mentored participants to engage in therapies that promote the learning of pain self-management skills and to support the mentored participants' practice of these skills. The study will examine the feasibility of this intervention for both mentors and mentored participants, and will assess the preliminary effectiveness of this program on mentored participants' pain and functional disability. Methods This protocol will recruit adolescents ages 12-17 with chronic pain and randomly assign them to either peer mentorship or a treatment-as-usual control group. Mentored participants will be matched with peer mentors of similar age (ages 14-18 who have actively participated in various treatment modalities through the UCLA Pediatric Pain Program and have learned to function successfully with a chronic pain disorder. The mentors will present information to mentored participants in a supervised and monitored telephone interaction for 2 months to encourage participation in skill-building programs. The control group will receive usual care but without the mentorship intervention. Mentored and control subjects' pain and functioning will be assessed at 2 months (end of intervention for mentored participants and

    The aim of this qualitative study is to explore the way people using modern health care perceive its consequences in Ouraman-e-Takht region of Iranian Kurdistan. Ouraman-e-Takht is a rural, highly mountainous and dry region located in the southwest Kurdistan province of Iran. Recently, modern health practices have been introduced to the region. The purpose of this study was to investigate, from the Ouramains' point of view, the impact that modern health services and practices have had on the Ouraman traditional way of life. Interview data from respondents were analyzed by using grounded theory. Promoting survival was the core category that explained the impact that modern health practices have had on the Ouraman region. The people of Ouraman interpreted modern health practices as increasing their quality of life and promoting their survival. Results are organized around this core category in a paradigm model consisting of conditions, interactions, and consequences. This model can be used to understand the impact of change from the introduction of modern health on a traditional society.

    Alzheimer's disease (AD) is an incurable neurodegenerative disease and many types of stem cells have been used in AD therapy with some favorable effects. In this study, we investigated the potential therapeutical effects of human dental pulp stem cells (hDPSCs) on AD cellular model which established by okadaic acid (OA)-induced damage to human neuroblastoma cell line, SH-SY5Y, in vitro for 24 h. After confirmed the AD cellular model, the cells were co-culture with hDPSCs by transwell co-culture system till 24 h for treatment. Then the cytomorphology of the hDPSCs-treated cells were found to restore gradually with re-elongation of retracted dendrites. Meanwhile, Cell Counting Kit-8 assay and Hoechst 33258 staining showed that hDPSCs caused significant increase in the viability and decrease in apoptosis of the model cells, respectively. Observation of DiI labeling also exhibited the prolongation dendrites in hDPSCs-treated cells which were obviously different from the retraction dendrites in AD model cells. Furthermore, specific staining of α-tubulin and F-actin demonstrated that the hDPSCs-treated cells had the morphology of restored neurons, with elongated dendrites, densely arranged microfilaments, and thickened microtubular fibrils. In addition, results from western blotting revealed that phosphorylation at Ser 396 of Tau protein was significantly suppressed by adding of hDPSCs. These results indicate that hDPSCs may promote regeneration of damaged neuron cells in vitro model of AD and may serve as a useful cell source for treatment of AD. © 2017 International Federation for Cell Biology.

  11. Promoting Visualization Skills through Deconstruction Using Physical Models and a Visualization Activity Intervention

    Schiltz, Holly Kristine

    Visualization skills are important in learning chemistry, as these skills have been shown to correlate to high ability in problem solving. Students' understanding of visual information and their problem-solving processes may only ever be accessed indirectly: verbalization, gestures, drawings, etc. In this research, deconstruction of complex visual concepts was aligned with the promotion of students' verbalization of visualized ideas to teach students to solve complex visual tasks independently. All instructional tools and teaching methods were developed in accordance with the principles of the theoretical framework, the Modeling Theory of Learning: deconstruction of visual representations into model components, comparisons to reality, and recognition of students' their problemsolving strategies. Three physical model systems were designed to provide students with visual and tangible representations of chemical concepts. The Permanent Reflection Plane Demonstration provided visual indicators that students used to support or invalidate the presence of a reflection plane. The 3-D Coordinate Axis system provided an environment that allowed students to visualize and physically enact symmetry operations in a relevant molecular context. The Proper Rotation Axis system was designed to provide a physical and visual frame of reference to showcase multiple symmetry elements that students must identify in a molecular model. Focus groups of students taking Inorganic chemistry working with the physical model systems demonstrated difficulty documenting and verbalizing processes and descriptions of visual concepts.

    Myocardial cell injury and cardiac myocyte apoptosis are associated with sepsis. Glutamine (Gln) has been reported to repair myocardial cell injury. The aim of this study was to explore the role of Gln on cardiac myocytes in a cecal ligation and puncture (CLP) model of sepsis in Wistar rats. Following induction of sepsis in a CLP rat model, viral encoding heat shock protein 90 (Hsp90) gene and Hsp90dsDNA were designed to express and knockdown Hsp90, respectively. Rat cardiac tissues were examined histologically, and apoptosis was detected by terminal deoxynucleotidyl transferase dUTP nick end labeling staining. The expression of B-cell lymphoma-2 (Bcl-2), Bcl-2-associated X protein, Hsp90, p53 upregulated modulator of apoptosis, and p53 was measured by western blotting and real-time polymerase chain reaction. Caspase-3, caspase-8, and caspase-9 were detected by enzyme-linked immunosorbent assay. Rat cardiac myocyte damage induced by CLP was reduced by Gln treatment and Hsp90 overexpression, and these changes were reversed by Hsp90 knockdown. Bcl-2 expression, Bcl-2-associated X protein, p53, p53 upregulated modulator of apoptosis, caspase-8, caspase-9, and caspase-3 activities were significantly upregulated in the CLP model, which were reduced by Gln treatment and Hsp90 overexpression. Gln reduced apoptosis of cardiac myocytes in a rat model of sepsis, by promoting Hsp90 expression. Further studies are needed to determine the possible therapeutic action of Gln in sepsis in human tissue. Copyright © 2017 Elsevier Inc. All rights reserved.

    Full Text Available There are plenty of reasons into choosing entrepreneurship as opposed to employee`s status: the most frequent being the independence and the financial gain of the entrepreneur. Furthermore, it could even be assimilated as an alternative livelihood to lack of employment or risk of becoming unemployed. Promoting entrepreneurship through an entrepreneurial curricular plays a major role in acquiring the key individual skillset needed. The enterprising spirit of the new generation is impacted by entrepreneurial education, developing the can do attitude and enforces it`s role within economy and the society. The required skillset that allows entrepreneurs to transform ideas into action are: creativity, innovation and risk appetite as well as goal and project management. The hereby paper is a quantitative research of entrepreneurial intent within economic studies graduates and the impact of the Romanian entrepreneurial promotion initiatives on the aforementioned.

    The effects of health promotion interventions are the result not only of the interventions themselves, but also of the contexts in which they unfold. The objective of this study was to analyze, through stakeholders' discourse, the characteristics of an intervention that can influence its outcomes. This case study was based on semi-structured interviews with health promotion stakeholders involved in a regional program (PRALIMAP). General hypotheses on transferability and on how the intervention is presumed to produce its effects were used to construct an interview guide. Interviews were analyzed using thematic coding. Twenty-three stakeholders were interviewed. Results showed stakeholders made few references to population and environment characteristics. Three themes emerged as significant for the stakeholders: implementation modalities and methodology, modalities used to mobilize actors; and transferability-promoting factors and barriers. Our work contributes to a better understanding not only of transferability factors, but also of stakeholders' perceptions of them, which are just as important, because those perceptions themselves are a factor in mobilization of actors, implementation, and transferability.

    Inflammatory bowel disease (IBD) is a chronic intestinal inflammatory condition. Psychological stress has been postulated to affect the clinical symptoms and recurrence of IBD. The exact molecular mechanisms are not fully understood. In the present study, we demonstrate that psychological stress promotes neutrophil infiltration into colon tissues in dextran sulfate sodium (DSS)-induced colitis model. The psychological stress resulted in abnormal expression of the proinflammatory cytokines (IL-1β, IL-6, IL-17A, and IL-22) and neutrophil chemokines (CXCL1 and CXCL2) and overactivation of the STAT3 inflammatory signaling pathway. Under chronic unpredictable stress, the adrenergic nervous system was markedly activated, as the expression of tyrosine hydroxylase, the rate-limiting enzyme in catecholamine biosynthesis, in bone marrow and colonic epithelium was enhanced, especially in the myenteric ganglia. The β-AR agonist isoproterenol mimicked the effects of psychological stress on neutrophilia, neutrophil infiltration, and colonic damage in DSS-induced colitis. The β1-AR/β2-AR inhibitor propranolol reduced the numbers of the neutrophils in the circulation, suppressed neutrophil infiltration into colonic tissues, and attenuated the colonic tissue damage promoted by chronic stress. Propranolol also abolished stress-induced upregulation of proinflammatory cytokines and neutrophil chemokines. Our data reveal a close linkage between the β1-AR/β2-AR activation and neutrophil trafficking and also suggest the critical roles of adrenergic nervous system in exacerbation of inflammation and damage of colonic tissues in experimental colitis. The current study provides a new insight into the mechanisms underlying the association of psychological stress with excessive inflammatory response and pathophysiological consequences in IBD. The findings also suggest a potential application of neuroprotective agents to prevent relapsing immune activation in the treatment of IBD

    To investigate associations of eHealth Literacy with health-promoting behaviours among hospital nurses in South Korea. Health-promoting behaviours of nurses are crucial for their own improved health and health-related behaviours of patients. eHealth literacy refers to the ability to search, understand and evaluate health information available online. With the growing use of the Internet, eHealth literacy is emerging as an important factor enhancing health-promoting behaviours. Descriptive cross-sectional design with self-reported questionnaires. Data were collected between March and May 2016 from five hospitals in South Korea. Health-promoting behaviours and eHealth literacy were assessed using Health Promoting Lifestyle Profile-II and K-eHEALS, respectively. Multiple linear regression models were used to examine associations of eHealth literacy and health-promoting behaviours. Nurses with high level of eHealth literacy had significantly positive overall health-promoting behaviours, stress management, interpersonal relations, self-actualization and health responsibility, but not for nutrition and physical activity. Improving eHealth literacy through various strategies could be an effective way to boost health-promoting behaviours among nurses. However, improvement of actual health-promoting behaviours such as nutrition and physical activity will require systematic and organizational changes. This article is protected by copyright.

    2015-03-01

    Full Text Available AIMS - The objective of this study was to identify factors that either promote or hinder implementation of a multicomponent Responsible Beverage Service programme in Swedish municipalities. DESIGN - Forty semi-structured interviews were conducted in six municipalities and directed content analysis, guided by the Consolidated Framework for Implementation Research (CFIR, was performed. RESULTS - The CFIR framework was useful as an underlying theoretical model in this study. Importance of the following factors, described in the five domains of CFIR, was empirically supported in this study: local needs, evidence strength and advantages of the intervention, costs and available resources, clear goals, evaluation and feedback, access to knowledge and information, clear role definitions and cooperation, and enthusiastic key persons with high confidence in the effectiveness of the intervention. Hindering factors listed by the informants were lack of enthusiasm and opportunities to specialise, low degree of self-efficacy, unengaged decision-makers, complexities of the programme, and a top-down approach. CONCLUSIONS - This study indicates that previously identified factors shown to promote and hinder implementation processes are also valid in the context of multicomponent community action programmes like RBS. Suggestions on how to elude some of the hindering factors are proposed, e.g. to develop long-time financial plans, to provide better information about the RBS program in full, and to stress the importance of collaboration between representatives from the municipalities, police authorities and owners of on-licenced premises.

    Promotive voice is essential for improving team and organization performance. Yet in the current literature, less was known regarding the psychological reasons why people engage in promotive voice. Through the lens of social exchange, we proposed that employees who received support from colleagues may develop higher level of felt obligation for constructive change which leads to promotive voice. Analyses of multi-source data from 51 cross-functional sources (51 team supervisors and 162 employees) showed that employees’ felt obligation for constructive change positively mediates the relationship between colleague support and promotive voice behavior. Moreover, the impact of colleague support on felt obligation for constructive change is stronger when there is a low level of subgroup formation in the team. Theoretical and practical implications of these findings are discussed. PMID:26148194

    2017-10-01

    Autosomal dominant polycystic kidney disease (ADPKD) is one of the most common monogenic hereditary disorders in humans characterized by fluid-filled cysts, primarily in the kidneys. Cux1, a cell cycle regulatory gene highly expressed during kidney development, is elevated in the cyst-lining cells of Pkd1 mutant mice, and in human ADPKD cells. However, forced expression of Cux1 is insufficient to induce cystic disease in transgenic mice or to induce rapid cyst formation after cilia disruption in the kidneys of adult mice. Here we report a double mutant mouse model that has a conditional deletion of the Pkd1 gene in the renal collecting ducts together with a targeted mutation in the Cux1 gene (Pkd1 CD ;Cux1 tm2Ejn ). While kidneys isolated from newborn Pkd1 CD mice exhibit cortical and medullary cysts, kidneys isolated from newborn Pkd1 CD ;Cux1 tm2Ejn-/- mice did not show any cysts. Because Cux1 tm2Ejn-/- are perinatal lethal, we evaluated Pkd1 CD mice that were heterozygote for the Cux1 mutation. Similar to the newborn Pkd1 CD ;Cux1 tm2Ejn-/- mice, newborn Pkd1 CD ;Cux1 tm2Ejn+/- mice did not show any cysts. Comparison of Pkd1 CD and Pkd1 CD ;Cux1 tm2Ejn+/- mice at later stages of development showed a reduction in the severity of PKD in the Pkd1 CD ;Cux1 tm2Ejn+/- mice. Moreover, we observed an increase in expression of the cyclin kinase inhibitor p27, a target of Cux1 repression, in the rescued collecting ducts. Taken together, our results suggest that Cux1 expression in PKD is not directly involved in cystogenesis but promotes cell proliferation required for expansion of existing cysts, primarily by repression of p27.

    As people with intellectual disabilities (ID) are living longer, their chances of developing cancer also increases. However, recognising the early signs and symptoms of cancer in a population with cognitive impairment and communication difficulties poses difficulties for both family carers and professional care staff. Engagement in health promotion and cancer prevention activities is also a challenge; yet, people with ID have an equal right to these important public services as other members of the population. The aim of this study was to examine how care staff engaged in cancer prevention and health promotion activities on behalf of people with ID. This was an exploratory descriptive study using a postal survey design employing a questionnaire. Fifteen residential facilities for adults with ID were targeted within one geographic region of the UK. In total, 40 residential staff completed a questionnaire about their knowledge of the risk and protective factors of stomach, breast, cervical and testicular cancer. Staff then completed questionnaires regarding 90 adults with ID, recording details about body mass index (BMI), lifestyle choices (i.e. smoking, dietary intake), Helicobacter pylori testing, family history of cancer and staff's health promotion and cancer prevention activities with these individuals. The women with ID were reported to have significantly higher BMIs than the men with ID and only two people with ID had been tested for the H. pylori infection: potential risk factors for developing breast and stomach cancer, respectively. The majority of the staff reported that they did not receive training in cancer prevention. Likewise, the majority of the staff reported that they were unaware of the family histories of the people with ID in their care. Reports varied with how staff engaged with people with ID regarding stomach, breast, cervical and testicular cancer health promotion activities and cancer screening opportunities. Findings of this study show

    The scope of this study is to analyze the implementation of health promotion actions in the working process of the Family Health Teams of a city in the state of Santa Catarina. It involves research adopting a qualitative approach linked to the methodological benchmark of Paulo Freire, consisting of three dialectic moments: thematic investigation; encoding and decoding; critical revelation. Fifteen Culture Circles were conducted, covering five district health units, with the participation of 70 professionals. Each meeting was scheduled to last two hours with an average attendance of thirteen participants of the Family Health teams. The research revealed that there are limitations to the implementation of health promotion as a key element of participatory action together with the community. It also highlighted the importance of interdisciplinarity and intersectorality between workers and the city, state and federal manager. The commitment to the principles of the Unified Health System (SUS) and health promotion also presents itself as a challenge to improve the quality of life of the population.

    Hand hygiene is an important component in infection control to protect patient safety and reduce health care-associated infection. Our aim was to evaluate the efficacy of different social media on the promotion of a hand hygiene (HH) program. The observational study was conducted from May 5 to December 31, 2014, at a 2600-bed tertiary care hospital. A 3-minute video of an HH campaign in 8 languages was posted to YouTube. The Chinese version was promoted through three platforms: the hospital website, the hospital group email, and the Facebook site of a well-known Internet illustrator. The video traffic was analyzed via Google Analytics. HH compliance was measured in November 2013 and 2014. There were 5252 views of the video, mainly of the Chinese-language version (3509/5252, 66.81%). The NTUH website had 24,000 subscribers, and 151 of them viewed the video (connection rate was 151/24,000, 0.63%). There were 9967 users of the hospital email group and the connection rate was 0.91% (91/9967). The connection rate was 6.17% (807/13,080) from Facebook, significantly higher than the other 2 venues (both Psocial media such as Facebook should be considered for future programs that promote hand hygiene and other healthy behaviors.

  14. A qualitative study of the promotion of exclusive breastfeeding by health professionals in Niamey, Niger

    2010-08-01

    Full Text Available Abstract Background The practice of exclusive breastfeeding depends on various factors related to both mothers and their environment, including the services delivered by health professionals. It is known that support and counseling by health professionals can improve rates, early initiation and total duration of breastfeeding, particularly exclusive breastfeeding. Mothers' decisions are influenced by health professionals' advice. However, in Niger the practice of exclusive breastfeeding is almost non-existent. The purpose of this exploratory study, of which some results are presented here, was to document health professionals' attitudes and practices with regard to exclusive breastfeeding promotion in hospital settings in the urban community of Niamey, Niger. Methods Fieldwork was conducted in Niamey, Niger. A qualitative approach was employed. Health professionals' practices were observed in a sample of frontline public healthcare facilities. Results The field observation results presented here indicate that exclusive breastfeeding is not promoted in healthcare facilities because the health professionals do not encourage it and their practices are inappropriate. Some still have limited knowledge or are misinformed about this practice or do not believe in it. They do not systematically discuss exclusive breastfeeding with mothers, or they mention it only briefly and without giving any explanation. Worse still, some encourage the use of breast milk substitutes, which are frequently promoted in healthcare facilities. Thus mothers often receive contradictory messages. Conclusion The results suggest the need to train or retrain health professionals with regard to exclusive breastfeeding, and regularly supervise their activities.

  15. Transgenic Studies with a Keratin Promoter-Driven Growth Hormone Transgene: Prospects for Gene Therapy

    1997-01-01

    Keratinocytes are potentially appealing vehicles for the delivery of secreted gene products because they can be transferred to human skin by the relatively simple procedure of grafting. Adult human keratinocytes can be efficiently propagated in culture with sufficient proliferative capacity to produce enough epidermis to cover the body surface of an average adult. However, the feasibility of delivering secreted proteins through skin grafting rests upon (i) the strength of the promoter in keratinocytes and (ii) the efficiency of protein transport through the basement membrane of the stratified epithelium and into the bloodstream. In this paper, we use transgenic technology to demonstrate that the activity of the human keratin 14 promoter remains high in adult skin and that keratinocyte-derived human growth hormone (hGH) can be produced, secreted, and transported to the bloodstream of mice with efficiency that is sufficient to exceed by an order of magnitude the circulating hGH concentration in growing children. Transgenic skin grafts from these adults continue to produce and secrete hGH stably, at ≈ 1/10 physiological levels in the bloodstream of nontransgenic recipient mice. These studies underscore the utility of the keratin 14 promoter for expressing foreign transgenes in keratinocytes and demonstrate that keratinocytes can be used as effective vehicles for transporting factors to the bloodstream and for eliciting metabolic changes. These findings have important implications for considering the keratinocyte as a possible vehicle for gene therapy.

    Presently, few options are available for refractory colorectal cancer (CRC). O6-methyl-guanine-DNA-methyltransferase (MGMT) promoter methylation is a frequent and early event in CRC tumourigenesis. This epigenetic silencing is a predictor of response to the alkylating drug temozolomide in glioblastoma. Preclinical evidences and some case reports showed temozolomide activity in CRC with MGMT silencing, but the available data from clinical trials are inconsistent. This was a multicentre, phase 2 trial, planned according to a two-stage Simon's optimal design to investigate activity and safety of temozolomide in refractory CRC harbouring MGMT promoter methylation. The primary end point was overall response rate (ORR). Patients who failed two or more prior treatments received temozolomide at a dose of 150-200 mg m -2 per day on days 1-5 every 28 days. From July 2012 to June 2016, 225 patients were screened, 80 showed MGMT promoter methylation and 41 were enrolled. Overall response rate was 10% and disease control rate was 32%. Median progression-free survival and overall survival were 1.9 and 5.1 months, respectively. Temozolomide showed a modest activity in this heavily pretreated population and the study did not meet its primary end point. The role of temozolomide in CRC remains still controversial and further research is warranted.

    Protective properties of moderate wine consumption against cancers, cardiovascular, metabolic and degenerative diseases have been reported in various clinical studies. Here, we analysed the effect of red wine (RW) and white wine (WW) on myelination using an in vitro embryonic co-culture mouse model. The total amount of myelin was found to be significantly increased after RW and WW treatment, while only RW significantly increased the number of internodes. Both types of wine increased rat Schwann cell- (rSC) expression of the NAD+-dependent deacetylase sirtuin-two-homolog 2 (Sirt2), a protein known to be involved in myelination. Detailed chemical analysis of RW revealed a broad spectrum of anthocyanins, piceids, and phenolics, including resveratrol (RSV). In our assay system RSV in low concentrations induced myelination. Furthermore RSV raised intracellular glutathione concentrations in rSCs and in co-cultures and therefore augmented antioxidant capacity. We conclude that wine promotes myelination in a rodent in vitro model by controlling intracellular metabolism and SC plasticity. During this process, RSV exhibits protective properties; however, the fostering effect on myelinaton during exposure to wine appears to be a complex interaction of various compounds. PMID:23762469

    The potential of systems science concepts to inform approaches for addressing complex public health problems, such as obesity prevention, has been attracting significant attention over the last decade. Despite its recent popularity, there are very few studies examining the application of systems science concepts, termed systems thinking, in practice and whether (if at all) it influences the implementation of health promotion in real world settings and in what ways. Healthy Together Victoria (HTV) was based on a systems thinking approach to address obesity prevention alongside other chronic health problems and was implemented across 14 local government areas. This paper examines the experience of practitioners from one of those intervention sites. In-depth interviews with eight practitioners revealed that there was a rigidity with which they had experienced previous health promotion jobs relative to the flexibility and fluidity of HTV. While the health promotion literature does not indicate that health promotion should be overly prescriptive, the experience of these practitioners suggests it is being applied as such in real world settings. Within HTV, asking people to work with 'systems thinking', without giving a prescription about what systems thinking is, enabled practitioners to be 'practice entrepreneurs' by choosing from a variety of systems thinking methods (mapping, reflection) to engage actively in their positions. This highlights the importance of understanding how key concepts, both traditional planning approaches and systems science concepts, are interpreted and then implemented in real world settings. © The Author 2017.

    Many state regulatory commissions and policymakers want utilities to aggressively pursue energy efficiency as a strategy to mitigate demand and energy growth, diversify the resource mix, and provide an alternative to building new, costly generation. However, as the National Action Plan for Energy Efficiency (NAPEE 2007) points out, many utilities continue to shy away from aggressively expanding their energy efficiency efforts when their shareholder's fundamental financial interests are placed at risk by doing so. Thus, there is increased interest in developing effective ratemaking and policy approaches that address utility disincentives to pursue energy efficiency or lack of incentives for more aggressive energy efficiency efforts. New regulatory initiatives to promote increased utility energy efficiency efforts also affect the interests of consumers. Ratepayers and their advocates are concerned with issues of fairness, impacts on rates, and total consumer costs. From the perspective of energy efficiency advocates, the quid pro quo for utility shareholder incentives is the obligation to acquire all, or nearly all, achievable cost-effective energy efficiency. A key issue for state regulators and policymakers is how to maximize the cost-effective energy efficiency savings attained while achieving an equitable sharing of benefits, costs and risks among the various stakeholders. In this study, we modeled a prototypical vertically-integrated electric investor-owned utility in the southwestern US that is considering implementing several energy efficiency portfolios. We analyze the impact of these energy efficiency portfolios on utility shareholders and ratepayers as well as the incremental effect on each party when lost fixed cost recovery and/or utility shareholder incentive mechanisms are implemented. A primary goal of our quantitative modeling is to provide regulators and policymakers with an analytic framework and tools that assess the financial impacts of

    Peer coaching provides an attractive alternative to traditional professional development for promoting classroom quality in a sustainable, cost-effective manner by creating a collaborative teaching community. This exploratory study describes the development and evaluation of the Colleague Observation And CoacHing (COACH) program, a peer coaching program designed to increase teachers' effectiveness in enhancing classroom quality in a preschool Head Start setting. The COACH program consists of a training workshop on coaching skills and student-teacher interactions, six peer coaching sessions, and three center meetings. Pre-post observations of emotional support, classroom organization, and instructional support using the Classroom Assessment Scoring System of twelve classrooms assigned to peer coaching were compared to twelve control classrooms at baseline and following the intervention. Findings provide preliminary support that the peer coaching program is perceived as acceptable and feasible by the participating preschool teachers and that it may strengthen student-teacher interactions. Further program refinement and evaluation with larger samples is needed to enhance student-teacher interactions and, ultimately, children's adaptive development.

    Full Text Available This research aims to study Pha Bong community’s dressing style and to develop a new ethnic costume that shows their identity to promote tourism in the province. Pha Bong Community is a community in Maehongson Province where two ethnic groups, people of Tai Yai (Shan and Sakor Karen, co-exist. The data collection methods include focus group and in-depth interview with target population, small group discussion and review of literature on costume development. The obtained data were then submitted to content analysis. First, it was found that they both have their own identity, resources, network marketing and inherited wisdom from their ancestors. Each group runs their business separately. Secondly, the research resulted in the creation of a new costume for the Pha Bong community created by members of two ethnic groups. This costume combines Karen symbol with Tai Yai (Shan clothing style. The motif and pattern of the fabric identify community members’ lifestyle, belief and value. It is recommended that development should be planned upon available resource and the need of the community. In addition, the community leader should encourage members to take parts in management and to cooperate for a sustainable development.

    Full Text Available Physical activity is an essential component of a healthy lifestyle, promoting health and preventing various chronic diseases. Despite this evidence, it is known that the younger generations invest much time in sedentary activities such as television viewing, videogames or reading, which potentially can lead to an increase in the prevalence of sedentary behaviors in adulthood. These behaviors have been identified as factors of disturbance in the balance between intake and energy expenditure, contributing to the increasing number of overweight and obese people and, further downstream, the prevalence of cardiovascular diseases and cancer (among others. The emergence of the Exergames (videogames that involve physical activity, either light, moderate or intense and games whose narrative alters pathogenic beliefs, contrary to the potential risk effect of gaming, by combining the playful context of videogames with physical activity (mild to intense. This study discusses some salutogenic principles of a new generation of videogames where virtual and real come together, ipromoting salutogenic behavioral patterns, namely through greater energy expenditure. The ideas are based on theoretical and empirical contributions from health psychology, in addition to the potential of computer technology applicable to traditional videogames and Exergames.

    Recommender systems (RS) are useful tools for filtering and sorting items and information for users. There is a wide diversity of approaches that help creating personalized recommendations. Context-aware recommender systems (CARS) are a kind of RS which provide adaptation capabilities to the user's environment, e.g., by sensing data through wearable devices or other biomedical sensors. In healthcare and wellbeing, CARS can support health promotion and health education, considering that each individual requires tailored intervention programs. Our research aims at proposing a context-aware mobile recommender system for the promotion of healthy habits. The system is adapted to the user's needs, his/her health information, interests, time, location and lifestyles. In this paper, the CARS computational architecture and the user and context models of health promotion are presented, which were used to implement and test a prototype recommender system.

    The development of Occupational Safety and Health Management System in textile industry will rejuvenate the workers and energize the economy as a whole. In India, especially in Tamil Nadu, approximately 1371 textile business is running with the help of 38,461 workers under Ginning, Spinning, Weaving, Garment and Dyeing sectors. Textile industry of contributes to the growth of Indian economy but it fails to foster education and health as key components of human development and help new democracies. The present work attempts to measure and develop OSHMS which reduce the hazards and risk involved in textile industry. Among all other industries textile industry is affected by enormous hazards and risk because of negligence by management and Government. It is evident that managements are not abiding by law when an accident has occurred. Managements are easily deceiving workers and least bothered about the Quality of Work Life (QWL). A detailed analysis of factors promoting safety and health to the workers has been done by performing confirmatory factor analysis, evaluating Risk Priority Number and the framework of OHMS has been conceptualized using Structural Equation Model. The data have been collected using questionnaire and interview method. The study finds occupation health for worker in Textile industry is affected not only by safety measure but also by technology and management. The work shows that difficulty in identifying the cause and effect of hazards, the influence of management in controlling and promoting OSHMS under various dimensions. One startling fact is existence of very low and insignificance correlation between health factors and outcome.

    The objective of the study was to design and evaluate a pilot programme aimed at promoting the active ageing of older adults at the Mexican Institute of Social Security. The study was conducted in three stages: (a) design; (b) implementation; and (c) before-after evaluation through analysis of changes in functional status, occupational functioning and health-related quality of life. To overcome the limitations of the study design, we evaluated the effect of 80 per cent adherence to the programme on the outcome variables using the generalised linear regression models (GLM). Two hundred and thirty-nine older adults agreed to participate, of whom 65 per cent completed the programme. Most were women; the average age was 77 years. Adherence to the programme was higher than 75 per cent for the group who completed active ageing services and less than 60 per cent for the drop-out group. Overall, 46 per cent of older adults reached an adherence level of 80 per cent or higher. Adherence was significantly associated with improved quality of life total score (coefficient 2.7, p <0.0001) and occupational functioning total score (coefficient 2.2, p <0.0001). Participation of older adults in an active ageing programme may improve their health-related quality of life and occupational functioning. It is necessary to identify the potential barriers and to implement strategies to improve the recruitment and retention rates during the intervention.

    Many wildlife studies seek to understand changes or differences in the proportion of sites occupied by a species of interest. These studies are hampered by imperfect detection of these species, which can result in some sites appearing to be unoccupied that are actually occupied. Occupancy models solve this problem and produce unbiased estimates of occupancy and related parameters. Required data (detection/non-detection information) are relatively simple and inexpensive to collect. Software is available free of charge to aid investigators in occupancy estimation.

    Evidence based practices (EBPs) in clinical settings interact with and adapt to host organizational characteristics. The contextual factors themselves, surrounding health professions' practices, also adapt as practices become sustained. The authors assert the need for better planning models toward these contextual factors, the influence of which undergird a well-documented science to practice gap in literature on EBPs. The mechanism for EBP planners to anticipate contextual effects as programs Unfreeze their host settings, create Movement, and become Refrozen (Lewin, 1951) is present in Lewin's 3-step change model. Planning for contextual change appears equally important as planning for the actual practice outcomes among providers and patients. Two case studies from a Geriatric Education Center network will illustrate the synthesis of Lewin's three steps with collaborative evaluation principles. The use of the model may become an important tool for continuing education evaluators or organizations beginning a journey toward EBP demonstration projects in clinical settings.

    To observe the effect and mechanism of Dendrobium candidum polysaccharides (DCP) in promoting hair growth, in order to lay a foundation for the development and utilization of D. candidum. The water-extraction and alcohol-precipitation method was adopted to extract DCP, and the phenol-sulphuric acid method was used to determine its content. Thirty C57BL6J mice were collected to establish the hair loss model with hair removal cream. They were randomly divided into the control group, the positive control group and the DCP group, and given 0.2 mL of ultra-pure water, minoxidil tincture and DCP (5.0 g x L(-1)) 21 days. The mice hair growth scoring standard was adopted to evaluate the hair growth of C57BL/6J mice at 7, 14 d. The hairs in unit hair-losing areas of treated C57BL/6J mice at 21 d were weighed to evaluate the effect of DCP on the promotion of hair growth. MTT assay and RT-PCR method were used to evaluate the effect of DCP on the proliferatin of HaCaT cells and the mRNA expression of VEGF in HaCaT cells. The extraction percent of DCP was 29.87%, and its content was 79.65%. The average scores for the hair growth and weight of C57BL/6J mice of DCP group were much higher than the control group. The survival rate and mRNA expression of VEGF of HaCaT cells were much higher than the control group. DCP has the effect in promoting hair growth. Its mechanism may be related to the up-regulation of the mRNA expression of VEGF.

    Full Text Available Abstract Background Overall the physical health of Indigenous men is among the worst in Australia. Research has indicated that modifiable lifestyle factors, such as poor nutrition and physical inactivity, appear to contribute strongly to these poor health conditions. To effectively develop and implement strategies to improve the health of Australia's Indigenous peoples, a greater understanding is needed of how Indigenous men perceive health, and how they view and care for their bodies. Further, a more systematic understanding of how sociocultural factors affect their health attitudes and behaviours is needed. This article presents the study protocol of a community-based investigation into the factors surrounding the health and body image of Indigenous Australian men. Methods and design The study will be conducted in a collaborative manner with Indigenous Australian men using a participatory action research framework. Men will be recruited from three locations around Australia (metropolitan, regional, and rural and interviewed to understand their experiences and perspectives on a number of issues related to health and health behaviour. The information that is collected will be analysed using modified grounded theory and thematic analysis. The results will then be used to develop and implement community events in each location to provide feedback on the findings to the community, promote health enhancing strategies, and determine future action and collaboration. Discussion This study will explore both risk and protective factors that affect the health of Indigenous Australian men. This knowledge will be disseminated to the wider Indigenous community and can be used to inform future health promotion strategies. The expected outcome of this study is therefore an increased understanding of health and health change in Indigenous Australian men, the development of strategies that promote healthy eating and positive patterns of physical activity and, in

    Full Text Available Folic acid supplementation may prevent the development of cancer in normal tissues but may promote the progression of established (preneoplastic lesions. However, whether or not folic acid supplementation can promote the progression of established (preneoplastic mammary lesions is unknown. This is a critically important issue because breast cancer patients and survivors in North America are likely exposed to high levels of folic acid owing to folic acid fortification and widespread supplemental use after cancer diagnosis. We investigated whether folic acid supplementation can promote the progression of established mammary tumors. Female Sprague-Dawley rats were placed on a control diet and mammary tumors were initiated with 7,12-dimethylbenza[a]anthracene at puberty. When the sentinel tumor reached a predefined size, rats were randomized to receive a diet containing the control, 2.5x, 4x, or 5x supplemental levels of folic acid for up to 12 weeks. The sentinel mammary tumor growth was monitored weekly. At necropsy, the sentinel and all other mammary tumors were analyzed histologically. The effect of folic acid supplementation on the expression of proteins involved in proliferation, apoptosis, and mammary tumorigenesis was determined in representative sentinel adenocarcinomas. Although no clear dose-response relationship was observed, folic acid supplementation significantly promoted the progression of the sentinel mammary tumors and was associated with significantly higher sentinel mammary tumor weight and volume compared with the control diet. Furthermore, folic acid supplementation was associated with significantly higher weight and volume of all mammary tumors. The most significant and consistent mammary tumor-promoting effect was observed with the 2.5x supplemental level of folic acid. Folic acid supplementation was also associated with an increased expression of BAX, PARP, and HER2. Our data suggest that folic acid supplementation may

    The goal of this project is the development, implementation and evaluation of a concept designed for sustainable health promotion among occupational and trade school teachers. We assume that for sustainable health promotion -- along with a behavioral prevention program -- a change is necessary in the structure, as well as, the working and communication processes within schools. The realization of early teacher participation and self regulated cooperative groups initiates comprehensive and goal-oriented developmental processes in the project schools. The organizational development process was accomplished in the following way: At the beginning we conducted a diagnosis of school-specific and individual health risks and the resources available to the project schools. The results were reported for both the individual and for the teacher group. This was intended to clarify the potential for improvement and, thus, strengthen the teachers' motivation toward processes of change. Following the diagnosis, the teachers chose areas of stress-related strain and then worked in groups to develop and implement behaviour and working condition-oriented intervention strategies for health promotion. The diagnosis results confirm the necessity of school-specific health promotion: the schools demonstrate very different demand and resource profiles. Furthermore, is has become evident that the central success factor for health promotion in schools is the teachers' willingness for change. The individual and group reports of the diagnosis results seem to have made clear how essential individual and organisational changes are.

    Organizational capacity building for health promotion (HP) is beneficial to the effective implementation of HP in organizational settings. The World Health Organization (WHO) Health Promoting Hospitals' (HPHs) initiative encourages hospitals to promote the health of their stakeholders by developing organizational capacity. This study analyzes an application case of one hospital of the HPH initiative in Taiwan, characterizes actions aiming at building organizational support to strengthen health gains and identifies facilitators of and barriers to the implementation of the HP in this hospital. Case study methodology was used with a triangulation of various sources; thematic analysis was used to analyze qualitative information. This study found a positive impact of the HPH initiative on the case hospital, such as more support from leadership, a fine-tuned HP mission and strategy, cultivated pro-HP habits of physical activities, a supportive intramural structure, an HP-inclusive system, improved management practices and enhanced staff participation. Transformational and transactional enablers are of equal importance in implementing HPH. However, it was also found that the case hospital encountered more transactional barriers than transformational ones. This hospital was hindered by insufficient support from external environments, leadership with limited autonomy and authority, a preference for ideals over professionalism, insufficient participation by physicians, a lack of manpower and time, a merit system with limited stimulating effect, ineffective management practices in weak central project management, a lack of integration, insufficient communication and an inability to inculcate the staff on the importance of HP, and inadequate staff participation. Several implications for other hospitals are suggested. © The Author (2014). Published by Oxford University Press. All rights reserved. For Permissions, please email: journals.permissions@oup.com.

    2016-11-01

    Empathy is the important capacity to recognize and share emotions with others. Recent evidence shows that rodents possess a remarkable affective sensitivity to the emotional state of others and that primitive forms of empathy exist in social lives of rodents. However, due to the ambiguous definitional boundaries between empathy, emotional contagion and other related terms, distinct components of empathic behaviors in rodents need to be clarified. Hence, we review recent experimental studies demonstrating that rodents are able to share emotions with others. Specifically, we highlight several behavioral models that examine different aspects of rodent empathic behaviors in response to the various distress of conspecifics. Experimental approaches using rodent behavioral models will help elucidate the neural circuitry of empathy and its neurochemical association. Integrating these findings with corresponding experiments in humans will ultimately provide novel insights into therapeutic interventions for mental disorders associated with empathy.

    To develop a model, based on market segmentation, to improve the quality and efficiency of health promotion materials and programs. Market segmentation to create segments (groups) based on a cross-sectional questionnaire measuring individual characteristics and preferences for health information. Educational and delivery recommendations developed for each group. General population of adults in Virginia. Random sample of 1201 Virginia residents. Respondents are representative of the general population with the exception of older age. Multiple factors known to impact health promotion including health status, health system utilization, health literacy, Internet use, learning styles, and preferences. Cluster analysis and discriminate analysis to create and validate segments. Common sized means to compare factors across segments. Developed educational and delivery recommendations matched to the 8 distinct segments. For example, the "health challenged and hard to reach" are older, lower literacy, and not likely to seek out health information. Their educational and delivery recommendations include a sixth-grade reading level, delivery through a provider, and using a "push" strategy. This model addresses a need to improve the efficiency and quality of health promotion efforts in an era of personalized medicine. It demonstrates that there are distinct groups with clearly defined educational and delivery recommendations. Health promotion professionals can consider Tailored Educational Approaches for Consumer Health to develop and deliver tailored materials to encourage behavior change.

    2013-01-01

    Full Text Available In order to understand how tumor cells can escape immune surveillance mechanisms and thus develop antitumor therapies, it is critically important to investigate the mechanisms by which the immune system interacts with the tumor microenvironment. In our current study, IL-17 deficiency results in reduced melanoma tumor size, diminished numbers of proliferating cells and blood vessels, and decreased percentage of CD11b+Gr-1+ MDSCs in tumor tissues. IL-17 promotes IL-6 induction and Stat3 activation. Treatment of Stat3 inhibitor WP1066 in B16-F10 tumor cells inoculated wild-type mice inhibits tumor growth. Additional administration of recombinant IL-6 into B16-F10 tumor-bearing IL-17−/− mice results in markedly increased tumor size and p-Stat3 expression, whereas additional recombinant IL-17 administration into B16-F10 tumor-bearing wild-type mice treated with anti-IL-6 mAb does not significantly alter the tumor growth and p-Stat3 expression. In our further study, blockade of Hmgb1-RAGE pathway inhibits melanoma tumor growth and reduces production of IL-23 and IL-17. All these data suggest that Hmgb1-IL-23-IL-17-IL-6-Stat3 axis plays a pivotal role in tumor development in murine models of melanoma, and blocking any portion of this axis will attenuate melanoma tumor growth.

    Songbirds famously learn their vocalizations. Some species can learn continuously, others seasonally, and still others just once. The zebra finch (Taeniopygia guttata) learns to sing during a single developmental "Critical Period," a restricted phase during which a specific experience has profound and permanent effects on brain function and behavioral patterns. The zebra finch can therefore provide fundamental insight into features that promote and limit the ability to acquire complex learned behaviors. For example, what properties permit the brain to come "on-line" for learning? How does experience become encoded to prevent future learning? What features define the brain in receptive compared to closed learning states? This piece will focus on epigenomic, genomic, and molecular levels of analysis that operate on the timescales of development and complex behavioral learning. Existing data will be discussed as they relate to Critical Period learning, and strategies for future studies to more directly address these questions will be considered. Birdsong learning is a powerful model for advancing knowledge of the biological intersections of maturation and experience. Lessons from its study not only have implications for understanding developmental song learning, but also broader questions of learning potential and the enduring effects of early life experience on neural systems and behavior.

    Neurogenesis is the process by which neural stem cells (NSCs) proliferate and differentiate into neurons. This is diminished in several neurodegenerative disorders such as Alzheimer's disease (AD), which is characterized by the deposition of amyloid (A)β peptides and neuronal loss. Stimulating NSCs to replace lost neurons is therefore a promising approach for AD treatment. Our previous study demonstrated that osthole modulates NSC proliferation and differentiation, and may reduce Aβ protein expression in nerve cells. Here we investigated the mechanism underlying the effects of osthole on NSCs. We found that osthole enhances NSC proliferation and neuronal differentiation while suppressing apoptosis, effects that were exerted via activation of Wnt/β-catenin signaling. These results provide evidence that osthole can potentially be used as a therapeutic agent in the treatment of AD and other neurodegenerative disorders. - Highlights: • An Alzheimer's disease model was successfully established by transfecting APP gene into neural stem cells in vitro. • Roles of osthole in experimental AD cells were studied. • Osthole promotes proliferation and differentiation into neurons and inhibits accumulation of Aβ 1–42 peptide and apoptosis. • Osthole exerts protection via Wnt/β-catenin signaling pathway.

    Increasing evidence from epidemiological and pathological studies suggests a role of the immune system in the initiation and progression of multiple cancers, including prostate cancer. Reports on the contribution of the adaptive immune system are contradictive, since both suppression and acceleration of disease development have been reported. This study addresses the functional role of lymphocytes in prostate cancer development using a genetically engineered mouse model (GEMM) of human c-Myc driven prostate cancer (Hi-Myc mice) combined with B and T cell deficiency (RAG1 -/- mice). From a pre-cancerous stage on, Hi-Myc mice showed higher accumulation of immune cells in their prostates then wild-type mice, of which macrophages were the most abundant. The onset of invasive adenocarcinoma was delayed in Hi-MycRAG1 -/- compared to Hi-Myc mice and associated with decreased infiltration of leukocytes into the prostate. In addition, lower levels of the cytokines CXCL2, CCL5 and TGF-β1 were detected in Hi-MycRAG1 -/- compared to Hi-Myc mouse prostates. These results from a GEMM of prostate cancer provide new insights into the promoting role of the adaptive immune system in prostate cancer development. Our findings indicate that the endogenous adaptive immune system does not protect against de novo prostate carcinogenesis in Hi-Myc transgenic mice, but rather accelerates the formation of invasive adenocarcinomas. This may have implications for the development of novel treatment strategies.

    The clean development mechanism (CDM) provides a way of assisting sustainable development in developing countries for developed countries to reduce greenhouse gas (GHG) emissions. Despite its intended benefits, the primary CDM market decreased from US$5.8 billion in 2006 to US$1.5 billion in 2010. One of the primary reasons for the reduction of market size is that developed countries as investors have a high level of risks caused by the volatility of the market price for certified emission reductions (CERs). Another issue to be resolved is that developing countries as host countries cannot claim any right to the CERs produced on their own land. This paper presents a real option-based model for both parties (developed and developing countries) to have their fair share of profits and risks by controlling the uncertainty associated with the future value of CERs. A case study illustrated that the proposed model can effectively attract investors to CDM projects leading to mitigation of climate change. - Highlights: ► This study focused on the risks associated with the uncertainty of future CER value in CDM projects. ► A real option-based model was developed for both parties in CDM to have fair share of profit and risk. ► Key variables and boundary conditions were identified for application of real option to CDM. ► The model allowed both parties to own options, which have an identical value. ► Hydropower plant projects in Indonesia were used to illustrate the implementation of the model

    Full Text Available The purpose of the article is to review the institutional system of entrepreneurship promotion that exists in Lithuania and to offer guidelines to improve it. The research results show that the unified institutional system of entrepreneurship promotion in Lithuania does not present: responsible institutions coordinate single measures and their implementation, but do not follow long-term general strategy. According to research findings, in order to improve the entrepreneurship promotion system of Lithuania there is a need to create the main institutional system out of responsable ministries (the Ministry of Education and Science, the Ministry of Economy, the Ministry of Agriculture, the Ministry of Social Security and Labour and define the boundaries of their responsibilities.

    Social media is being used by various stakeholders among pharmaceutical companies, government agencies, health care organizations, professionals, and news media as a way of engaging audiences to raise disease awareness and ultimately to improve public health. Nevertheless, it is unclear what effects this health information has on laypeople. This study aimed to provide a detailed examination of how promotional health information related to Lynch syndrome impacts laypeople's discussions on a social media platform (Twitter) in terms of topic awareness and attitudes. We used topic modeling and sentiment analysis techniques on Lynch syndrome-related tweets to answer the following research questions (RQs): (1) what are the most discussed topics in Lynch syndrome-related tweets?; (2) how promotional Lynch syndrome-related information on Twitter affects laypeople's discussions?; and (3) what impact do the Lynch syndrome awareness activities in the Colon Cancer Awareness Month and Lynch Syndrome Awareness Day have on laypeople's discussions and their attitudes? In particular, we used a set of keywords to collect Lynch syndrome-related tweets from October 26, 2016 to August 11, 2017 (289 days) through the Twitter public search application programming interface (API). We experimented with two different classification methods to categorize tweets into the following three classes: (1) irrelevant, (2) promotional health information, and (3) laypeople's discussions. We applied a topic modeling method to discover the themes in these Lynch syndrome-related tweets and conducted sentiment analysis on each layperson's tweet to gauge the writer's attitude (ie, positive, negative, and neutral) toward Lynch syndrome. The topic modeling and sentiment analysis results were elaborated to answer the three RQs. Of all tweets (N=16,667), 87.38% (14,564/16,667) were related to Lynch syndrome. Of the Lynch syndrome-related tweets, 81.43% (11,860/14,564) were classified as promotional and 18

    Understanding of underlying mechanisms of drastic variations of the near-Earth space (geospace) is one of the current focuses of the magnetospheric physics. The science target of the geospace research project Exploration of energization and Radiation in Geospace (ERG) is to understand the geospace variations with a focus on the relativistic electron acceleration and loss processes. In order to achieve the goal, the ERG project consists of the three parts: the Arase (ERG) satellite, ground-based observations, and theory/modeling/integrated studies. The role of theory/modeling/integrated studies part is to promote relevant theoretical and simulation studies as well as integrated data analysis to combine different kinds of observations and modeling. Here we provide technical reports on simulation and empirical models related to the ERG project together with their roles in the integrated studies of dynamic geospace variations. The simulation and empirical models covered include the radial diffusion model of the radiation belt electrons, GEMSIS-RB and RBW models, CIMI model with global MHD simulation REPPU, GEMSIS-RC model, plasmasphere thermosphere model, self-consistent wave-particle interaction simulations (electron hybrid code and ion hybrid code), the ionospheric electric potential (GEMSIS-POT) model, and SuperDARN electric field models with data assimilation. ERG (Arase) science center tools to support integrated studies with various kinds of data are also briefly introduced.[Figure not available: see fulltext.

    Occupational therapy can contribute to sexual and reproductive health through health education. The purpose of this study was to describe an occupational therapy intervention aimed at sexual and reproductive health promotion in adolescents. Fifty-eight adolescents were involved in the study, before, during and after the interventions. Educative activities such as puzzles, storytelling, mime and board games were used, which occupational therapy faculty and students had constructed. The games were employed as mediators for gaining knowledge in sexual and reproductive health. Outcome was measured using a questionnaire, audio recordings and field diaries. The data were analysed by descriptive statistics and thematic content analysis. The results showed the adolescents' increased knowledge of sexual and reproductive health information immediately after the intervention. The thematic analysis was grouped into three categories: the adolescents' initial expectations regarding the project, reflections on the process experienced during the interventions and use of educational games by occupational therapists. The importance of rapport and dialogue was highlighted in the construction of interventions based on participatory methods. The absence of a longitudinal follow-up is a limitation in this study. Further research is important to systematically assess sexual health promotion strategies in adolescence. Copyright © 2015 John Wiley & Sons, Ltd.

    Nurse educators are calling for the transformation of nursing education toward curricula that promote clinical reasoning through reflective practice and understanding of patient experiences in an effort to motivate students to become change agents. Study abroad programs can play an important role in this transformation through educating nurses in the delivery of culturally safe health care in a diverse world. Exposing nursing students to study abroad experiences that are guided by critical approaches such as a postcolonial feminist framework provides nursing students with opportunities to be immersed in the life and culture of people who have a completely different positioning and location while reflecting on the "us" versus "them" phenomenon that is pervasive in modern Western society and generates negative cultural comparisons. Attention to the design and implementation of such programs is important if nursing schools in the Western world are to uphold ethical standards, promote equality in relationships with host communities and avoid inadvertent exploitation and marginalization of vulnerable peoples. We present the development and implementation of a community health study abroad program for American nursing students in Malawi, Africa using a postcolonial feminist framework.

    The relationship between effective organisation of general practices and health improvement is widely accepted. The Maturity Matrix is an instrument designed to assess organisational development in general practice settings and to stimulate quality improvement. It is undertaken by a practice team with the aid of a facilitator. There is a tradition in the primary care systems in many countries of using practice visitors to educate practice teams about how to improve. However the role of practice visitors as facilitators who enable teams to plan practice-led organisational development using quality improvement instruments is less well understood. The objectives of the study were to develop and explore a facilitation model to support practice teams in stimulating organisational development using a quality improvement instrument called the Maturity Matrix. A qualitative study based on transcript analysis was adopted. A model of facilitation was constructed based on a review of relevant literature. Audio tapes of Maturity Matrix assessment sessions with general practices were transcribed and facilitator skills were compared to the model. The sample consisted of two facilitators working with twelve general practices based in UK primary care. The facilitation model suggested that four areas describing eighteen skills were important. The four areas are structuring the session, obtaining consensus, handling group dynamics and enabling team learning. Facilitators effectively employed skills associated with the first three areas, but less able to consistently stimulate team learning. This study suggests that facilitators need careful preparation for their role and practices need protected time in order to make best use of practice-led quality improvement instruments. The role of practice visitor as a facilitator is becoming important as the need to engender ownership of the quality improvement process by practices increases.

Traditional promoter analysis is mainly based on sequence compositional features. Recently, many kinds of structural features have been employed in promoter prediction. However, considering the high-dimensionality and overfitting problems, it is unfeasible to utilize all available features for promoter prediction. Thus it is necessary to choose some appropriate features for t...

    Despite recommendations and the need to accelerate redesign of delivery models to be team-based and patient-centred, professional silos and cultural and structural barriers that inhibit working together and communicating effectively still predominate in the hospital setting. Aiming to improve team-based rounding, we developed, implemented and evaluated the Interprofessional Teamwork Innovation Model (ITIM). This quality improvement (QI) study was conducted at an academic medical centre. We followed the system's QI framework, FOCUS-PDSA, with Lean as guiding principles. Primary outcomes included 30-day all-cause same-hospital readmissions and 30-day emergency department (ED) visits. The intervention group consisted of patients receiving care on two hospitalist ITIM teams, and patients receiving care from other hospitalist teams were matched with a control group. Outcomes were assessed using difference-in-difference analysis. Team members reported enhanced communication and overall time savings. In multivariate modelling, patients discharged from hospitalist teams using the ITIM approach were associated with reduced 30-day same-hospital readmissions with an estimated point OR of 0.56 (95% CI 0.34 to 0.92), but there was no impact on 30-day same-hospital ED visits. Difference-in-difference analysis showed that ITIM was not associated with changes in average total direct costs nor average cost per patient day, after adjusting for all other covariates in the models, despite the addition of staff resources in the ITIM model. The ITIM approach facilitates a collaborative environment in which patients and their family caregivers, physicians, nurses, pharmacists, case managers and others work and share in the process of care. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    Full Text Available Objectives: The present study aimed to analyze the factors that could affect the health-promoting behaviors of North Korean adolescent refugees residing in South Korea. Methods: Questions about their sociodemographic variables, subjective health status, healthy living habits, and health-promoting behaviors were asked. Results: Statistically significant differences were found in religion (t=2.30, p<0.05, having family members in South Korea (t=2.02, p<0.05, and subjective health status (t=4.96, p<0.01. Scores on health-responsible behaviors were higher with higher age (t=2.90, p<0.01 and for subjects without family or friends (t=2.43, p<0.05. Higher physical-activity behaviors were observed in males (t=3.32, p<0.01, in those with better subjective health status (t=3.46, p<0.05 and lower body mas index (t=3.48, p<0.05, and in smokers (t=3.17, p<0.01. Nutritional behaviors were higher in those who followed a religion (t=2.17, p<0.05. Spiritual growth behaviors were higher in those who followed a religion (t=4.21, p<0.001, had no family in South Korea (t=2.04, p<0.05, and had higher subjective health status (t=5.74, p<0.01. Scores on interpersonal relationships and stress-management behaviors were higher for those with higher subjective health status. A multiple regression analysis showed greater effects on health-promoting behaviors when subjective health status was better. Older people and non-smokers exhibited more health-responsible behaviors, while more physical-activity behaviors and spiritual growth activities were observed when subjective health status was better. Interpersonal relationship behaviors had positive effects on those with good subjective heath status and on non-smokers. Conclusions: Based on the results of the current study, an alternative was suggested for promoting health in North Korean adolescent refugees.

    Full Text Available Summary: Background: Exposure to particulate air pollution has been linked with risk of carcinogenesis. Damage to repair pathways might have long-term adverse health effects. We aimed to investigate the association of prenatal exposure to air pollution with placental mutation rate and the DNA methylation of key placental DNA repair genes. Methods: This cohort study used data from the ongoing ENVironmental Influence ON early AGEing (ENVIRONAGE birth cohort, which enrols pairs of mothers and neonates (singleton births only at the East-Limburg Hospital (Genk, Belgium. Placental DNA samples were collected after birth. We used bisulfite-PCR-pyrosequencing to investigate the mutation rate of Alu (a marker for overall DNA mutation and DNA methylation in the promoter genes of key DNA repair and tumour suppressor genes (APEX1, OGG1, PARP1, ERCC1, ERCC4, p53, and DAPK1. We used a high-resolution air pollution model to estimate exposure to particulate matter with a diameter less than 2·5 μm (PM2·5, black carbon, and NO2 over the entire pregnancy on the basis of maternal address. Alu mutation was analysed with a linear regression model, and methylation values of the selected genes were analysed in mixed-effects models. Effect estimates are presented as the relative percentage change in methylation for an ambient air pollution increment of one IQR (ie, the difference between the first and third quartiles of exposure in the entire cohort. Findings: 500 biobanked placental DNA samples were randomly selected from 814 pairs of mothers and neonates who were recruited to the cohort between Feb 1, 2010, and Dec 31, 2014, of which 463 samples met the pyrosequencing quality control criteria. IQR exposure increments were 3·84 μg/m3 for PM2·5, 0·36 μg/m3 for black carbon, and 5·34 μg/m3 for NO2. Among these samples, increased Alu mutation rate was associated with greater exposure to PM2·5 (r=0·26, p<0·0001 and black carbon (r=0·33, p<0·0001, but not NO2

    This paper seeks to review the current international health-promoting sports club (HPSC) research, drawing together findings based on case studies from various countries to illustrate the status of HPSCs. In addition, future challenges for HPSC research and implementation are considered. The review includes six case studies from five countries. In summary, there are two major research themes in this area, namely 'research into HPSC activity' and 'research into HPSC networks'. The first theme investigates the extent to which sports clubs and/or national sports organisations invest in health promotion (HP) - both in policy and practice. The latter theme is driven by an intention to widen the scope of HPSCs to reach novel internal actors, like parents, siblings, etc., and/or external non-sporting bodies, like communities, schools, etc. The future challenges for HPSC research require a better understanding of the motives, barriers and capacities of sports clubs and coaches. Sports organisations, clubs and coaches generally support the intent of the HPSC concept, but even with the best evidence- or theory-based HP programmes/guidelines/standards, nothing will happen in practice if the nature and capacities of sports clubs are not better acknowledged. Therefore, a call for embracing implementation science is finally made to enhance implementation. © The Author(s) 2015.

    Increasing the healthfulness of campus food environments is an important step in promoting healthful food choices among college students. This study explored university students' suggestions on promoting healthful food choices from campus vending machines. It also examined factors influencing students' food choices from vending machines. Peer-led semi-structured individual interviews were conducted with 43 undergraduate students (33 females and 10 males) recruited from students enrolled in an introductory nutrition course in a large national university in the United Arab Emirates. Interviews were audiotaped, transcribed, and coded to generate themes using N-Vivo software. Accessibility, peer influence, and busy schedules were the main factors influencing students' food choices from campus vending machines. Participants expressed the need to improve the nutritional quality of the food items sold in the campus vending machines. Recommendations for students' nutrition educational activities included placing nutrition tips on or beside the vending machines and using active learning methods, such as competitions on nutrition knowledge. The results of this study have useful applications in improving the campus food environment and nutrition education opportunities at the university to assist students in making healthful food choices.

    Chuanyi Ning

    Full Text Available OBJECTIVE: Three models for promoting male circumcision (MC as a preventative intervention against HIV infection were compared among migrant worker populations in western China. METHODS: A cohort study was performed after an initial cross-sectional survey among migrant workers in three provincial level districts with high HIV prevalence in western China. A total of 1,670 HIV seronegative male migrants were cluster-randomized into three intervention models, in which the dissemination of promotional materials and expert- and volunteer-led discussions are conducted in one, two, and three stage interventions. Changes in knowledge of MC, acceptability of MC, MC surgery uptake, and the costs of implementation were analyzed at 6-month and 9-month follow-up visits. RESULTS: All three models significantly increased the participants' knowledge about MC. The three-stage model significantly increased the acceptability of MC among participants and led to greatest increase in MC uptake. At the end of follow-up, 9.2% (153/1,670 of participants underwent MC surgery; uptake among the one-, two-, and three-stage models were 4.9%, 9.3%, and 14.6%, respectively. Multivariable Cox regression analysis showed that three-stage model was the most effective method to scale up MC, with RR = 2.0 (95% CI, 1.3-3.1, P=0.002 compared to the on-site session model. The two-stage intervention model showed no significant difference with either the on-site session model (RR=1.5, 95% CI, 0.92-2.4, P=0.12 or three-stage model (P=0.10. CONCLUSIONS: A three-stage intervention with gradual introduction of knowledge led to the significantly increase in MC uptake among migrant workers in western China, and was also the most cost-effective method among the three models.

    Although the promotion of social inclusion through sports has received increased attention with other disadvantaged groups, this is not the case for children and adults with intellectual disability who experience marked social isolation. The study evaluated the outcomes from one sports programme with particular reference to the processes that were perceived to enhance social inclusion. The Youth Unified Sports programme of Special Olympics combines players with intellectual disabilities (called athletes) and those without intellectual disabilities (called partners) of similar skill level in the same sports teams for training and competition. Alongside the development of sporting skills, the programme offers athletes a platform to socialise with peers and to take part in the life of their community. Unified football and basketball teams from five countries--Germany, Hungary, Poland, Serbia and Ukraine--participated. Individual and group interviews were held with athletes, partners, coaches, parents and community leaders: totalling around 40 informants per country. Qualitative data analysis identified four thematic processes that were perceived by informants across all countries and the two sports to facilitate social inclusion of athletes. These were: (1) the personal development of athletes and partners; (2) the creation of inclusive and equal bonds; (3) the promotion of positive perceptions of athletes; and (4) building alliances within local communities. Unified Sports does provide a vehicle for promoting the social inclusion of people with intellectual disabilities that is theoretically credible in terms of social capital scholarship and which contains lessons for advancing social inclusion in other contexts. Nonetheless, certain limitations are identified that require further consideration to enhance athletes' social inclusion in the wider community. © 2012 The Authors.

    Price boards in tobacco retailers are one of the few forms of tobacco promotion remaining in Australia. This study aimed to examine how these boards were used to promote products over a period of rapidly rising taxes. Observations were made in a panel of 350 stores in Melbourne, Australia, in November of 2013 (just before) and in 2014 and 2015 (after 12.5% increases in tobacco duty). Fieldworkers unobtrusively noted the presence and characteristics of price boards, and the brand name, size and price of the product at the top of each board. Price boards were common in all store types apart from newsagent/lottery agents. The characteristics of the top-listed product changed notably over time: premium brands accounted for 66% of top-listed products in 2013, significantly declining to 43% in 2015, while packs of 20 cigarettes increased in prominence from 32% to 45%. The prevalence of packs of 20 cigarettes in budget market segments tripled from 2013 (13%) and 2014 (11%) to 32% in 2015, with no change in the proportion of packs that were under $A20 from 2014 (37%) to 2015 (36%). The rate of increase in the average price of the top-listed pack correspondingly flattened from 2014 to 2015 compared with 2013-2014. Price boards promote tobacco products in ways that undermine the effectiveness of tax policy as a means of discouraging consumption. Communication to consumers about prices should be restricted to information sheets provided to adult smokers on request at the point of sale. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    Heart failure (HF) is a condition due to a problem with the structure or function of the heart impairs its ability to supply sufficient blood flow to meet the body's needs. In developing countries, around 2% of adults suffer from heart failure, but in people over the age of 65, this rate increases to 6-10%. In Iran, around 3.3% of adults suffer from heart failure. The Health Belief Model (HBM) is one of the most widely used models in public health theoretical framework. This was a cohort experimental study, in which education as intervention factor was presented to case group. 180 Heart failure patients were randomly selected from patients who were referred to the Shahid Rajaee center of Heart Research in Tehran and allocated to two groups (90 patients in the case group and 90 in the control group). HBM was used to compare health behaviors. The questionnaire included 69 questions. All data were collected before and 2 months after intervention. About 38% of participants don't know what, the heart failure is and 43% don't know that using the salt is not suitable for them. More than 40% of participants didn't weigh any time their selves. There was significant differences between the mean grades score of variables (perceived susceptibility, perceived threat, knowledge, Perceived benefits, Perceived severity, self-efficacy Perceived barriers, cues to action, self- behavior) in the case and control groups after intervention that was not significant before it. Based on our study and also many other studies, HBM has the potential to be used as a tool to establish educational programs for individuals and communities. Therefore, this model can be used effectively to prevent different diseases and their complications including heart failure. © 2013 Tehran University of Medical Sciences. All rights reserved.

    This study was to investigate the sleep promoting effects of combined γ-aminobutyric acid (GABA) and 5-hydroxytryptophan (5-HTP), by examining neuronal processes governing mRNA level alterations, as well as assessing neuromodulator concentrations, in a fruit fly model. Behavioral assays were applied to investigate subjective nighttime activity, sleep episodes, and total duration of subjective nighttime sleep of two amino acids and GABA/5-HTP mixture with caffeine treated flies. Also, real-time PCR and HPLC analysis were applied to analyze the signaling pathway. Subjective nighttime activity and sleep patterns of individual flies significantly decreased with 1% GABA treatment in conjunction with 0.1% 5-HTP treatment (pHTP mixture resulted in significant differences between groups related to sleep patterns (40%, pHTP mixture significantly increased GABA levels 1h and 12h following treatment (2.1 fold and 1.2 fold higher than the control, respectively) and also increased 5-HTP levels (0 h: 1.01 μg/protein, 12h: 3.45 μg/protein). In this regard, we successfully demonstrated that using a GABA/5-HTP mixture modulates subjective nighttime activity, sleep episodes, and total duration of subjective nighttime sleep to a greater extent than single administration of each amino acid, and that this modulation occurs via GABAergic and serotonergic signaling.

  10. Analogy for Drude’s free electron model to promote students’ understanding of electric circuits in lower secondary school

    2014-09-01

    Full Text Available Aiming at a deep understanding of some basic concepts of electric circuits in lower secondary schools, this work introduces an analogy between the behavior of children playing in a school yard with a central lake, subject to different conditions, rules, and stimuli, and Drude’s free electron model of metals. Using this analogy from the first school contacts with electric phenomena, one can promote students’ understanding of concepts such as electric current, the role of generators, potential difference effects, energy transfer, open and closed circuits, resistances, and their combinations in series and parallel. One believes that through this analogy well-known previous misconceptions of young students about electric circuit behaviors can be overcome. Furthermore, students’ understanding will enable them to predict, and justify with self-constructed arguments, the behavior of different elementary circuits. The students’ predictions can be verified—as a challenge of self-produced understanding schemes—using laboratory experiments. At a preliminary stage, our previsions were confirmed through a pilot study with three classrooms of 9th level Portuguese students.

    Dendritic cells (DC) are rare, bone marrow (BM)-derived innate immune cells that critically maintain self-tolerance in the healthy steady-state. Regulatory DC (DCreg) with capacity to suppress allograft rejection and promote transplant tolerance in pre-clinical models can readily be generated from BM precursors or circulating blood monocytes. These DCreg enhance allograft survival via various mechanisms, including promotion of regulatory T cells. In non-human primates receiving minimal immunosuppressive drug therapy (IS), infusion of DCreg of donor origin, one week before transplant, safely prolongs renal allograft survival and selectively attenuates anti-donor CD8 + memory T cell responses in the early post-transplant period. Based on these observations, and in view of the critical need to reduce patient dependence on non-specific IS agents that predispose to cardiometabolic side effects and renal insufficiency, we will conduct a first-in-human safety and preliminary efficacy study of donor-derived DCreg infusion to achieve early (18 months post-transplant) complete IS withdrawal in low-risk, living donor liver transplant recipients receiving standard-of-care IS (mycophenolate mofetil, tacrolimus and steroids). We will test the hypothesis that, although donor-derived DCreg are short-lived, they will induce robust donor-specific T cell hyporesponsiveness. We will examine immunological mechanisms by sequential analysis of blood and tissue samples, incorporating cutting-edge technologies.

    It is recognised that the worksite catering sector is likely to play a pivotal role in influencing dietary intake in adults of working age. The present study aimed to assess the feasibility of engaging worksites in a healthy eating intervention, implementing a price incentivised main meal intervention and measuring indicative intervention responses to inform the design of a future trial. Workplaces registered with the Scottish Healthy Living Award were invited to participate. The EatSMART intervention (a reduced price, healthy meal combination plus promotions) was implemented over 10 weeks in two worksites. Implementation was assessed by observational and sales data. Indicative effects on food habits were measured using online pre- and post-intervention questionnaires. Focus group discussions and interviews were used to determine catering staff and consumer acceptability. Thirty-seven worksites were invited to participate and four worksites responded positively. Two sites (with 1600 and 500 employees, respectively) participated. Both required significant implementation support. Estimated sales data indicated that the uptake of promoted items varied by week (range 60-187 items) and by site. A poor response rate from questionnaires limited the evaluation of intervention impact. Consumers reported improved value for money and quality. Both sites reported an intention to continue the intervention delivery. Significant efforts are required to engage worksite catering teams and implement healthy eating interventions. Evaluation methods require further development to improve data collection. Responses from consumers and catering staff suggest that further work in this area would be welcomed. © 2014 The British Dietetic Association Ltd.

    Prolonged breastfeeding can prevent or limit the severity of a variety of diseases and conditions. Although evidence clearly shows that there are health benefits for breastfeeding, adherence to breastfeeding remains a key challenge facing maternal health providers in Saudi Arabia. The purpose of this study is to evaluate the impacts of a social media platform (Twitter) to promote breastfeeding in Saudi Arabia. Between February 10 and March 25, 2015, a web-based questionnaire was administered to evaluate the impacts of a Twitter based educational campaign on the awareness, knowledge, and adherence to breastfeeding behavior for women in Saudi Arabia. The overall response rate among mothers with a newborn child was 83% (n=484). The results showed an increase in the knowledge and awareness of breastfeeding practices and adherence among Twitter followers. The initiation rate of breastfeeding had slightly increased among women who never had previously breastfed. More women reported their willingness to continue exclusive breastfeeding and to stop bottle-feeding. Results also show that an integration of professional breastfeeding support, public health education programs through social media could be an effective tool in promoting breastfeeding in Saudi Arabia. There is a need for further research on designing and implementing a social media based educational outreach program to increase women's awareness, knowledge, and adherence to breastfeeding behavior in Saudi Arabia.

    This pilot study was undertaken to investigate whether music therapy is effective in promoting prosocial behaviors in aggressive adolescent boys who have social, emotional, and learning difficulties. Fifteen subjects (aged 11-15 years), enrolled at a special residential school in New Zealand, were randomly assigned to music therapy treatment groups (n = 6, n = 5), and a waitlist control group (n = 4). Examination of demographic data identified differences between groups for diagnosis (p =.044), with Group 1 all having Attention Deficit Hyperactivity Disorder (ADHD), and for age (p =.027), with Group 2 having a mean age 1.38 years older. Measures included parent and teacher versions of the Developmental Behaviour Checklist (DBC-P & DBC-T) (Einfeld & Tonge, 1994; Einfeld, Tonge, & Parmenter, 1998). While no definite treatment effects could be detected, results suggest that a music therapy program promoting autonomy and creativity may help adolescents to interact more appropriately with others in a residential villa setting, but might also lead to a temporary mild increase in disruptive behavior in the classroom. A more highly structured program and smaller group numbers may be advantageous for boys who have ADHD.

    The paper analyses unlabelled advertorials about health products in four life-style magazines and three daily newspapers' life-style supplements in Slovenia. Based on 250 hours of observing the production practice, 20 in-depth interviews with the main participants and a textual analysis of 247 advertorials, supported by three detailed case studies, the process of unlabelled advertorial production was unveiled, reasons for their production explained and their discursive elements of promotion uncovered. Despite their typical news-like appearance, advertorials focus on a product's positive characteristics only and represent an oversimplified viewpoint on health, primarily oriented towards the interest of the pharmaceutical industry. In advertorials, readers are instructed in healthy living and caring about their health through buying the promoted product. No particular differences were found between the magazines and quality dailies' supplements, indicating that the advertorial practice has become a common part of the Slovenian press media scene. The outburst of advertorials in Slovenia is outstanding due to the lack of historical democracy, problems with the supervision of legal transgressions, the small media and advertising market, economic downturns and the financial weakness of the media.

    Full Text Available Research suggests that many individuals with autism spectrum disorder (ASD often demonstrate challenges providing appropriate levels of information during conversational interchanges. Considering the preference of individuals with ASD, and recent rapid technological advances, robotic systems may yield promise in promoting certain aspects of conversation and interaction such as self-disclosure of appropriate personal information. In the current work, we evaluated personal disclosures of events with specific emotional content across two differing robotic systems (android and simplistic humanoid and human interactions. Nineteen participants were enrolled in this study: 11 (2 women and 9 men adolescents with ASD and 8 (4 women and 4 men adolescents with TD. Each participant completed a sequence of three interactions in a random order. Results indicated differences regarding comfort level and length of disclosures between adolescents with ASD and typically developing (TD controls in relation to system interactions. Specifically, adolescents with ASD showed a preference for interacting with the robotic systems compared to TD controls and demonstrated lengthier disclosures when interacting with the visually simple humanoid robot compared to interacting with human interviewer. The findings suggest that robotic systems may be useful in eliciting and promoting aspects of social communication such as self-disclosure for some individuals with ASD.

    Following the trend in most developed countries, in Austria the oldest old are the fastest growing population group. Among this group, there is a high prevalence of multimorbidity, functional impairment, dementia and psychiatric conditions. While health promotion (HP) has been considered relevant in coping with the challenges of an aging population, it has so far been viewed as a foreign concept in relation to the oldest old, especially those living in residential aged care (RAC) facilities. Although there is an acknowledgement that HP should be integrated into routine nursing, there has been little research on how professionals working with RAC interpret and implement HP. In this study, 13 semi-structured interviews were carried out with professionals from four major Austrian RAC providers. The data were analysed using thematic analysis. The findings show that, typically, professionals understand HP as a concept that is oriented towards maintaining potentials and resources, thereby promoting self-determination, autonomy and social integration, including frail and functionally impaired elderly residents. However, data analysis also revealed a gap between the conceptual understanding and positive attitudes towards HP and its implementation in practice. Implementation of HP seems to occur in isolated cases, related to specific health issues. It seems that more complex HP approaches, especially the 'settings approach', are hardly practiced. To implement more comprehensive and systematic HP in Austrian RAC, support from external HP agencies as well as changes in financial incentives are needed.

    A new disposal unit, designated as Saltstone Disposal Unit 6 (SDU6), is being designed for support of site accelerated closure goals and salt waste projections identified in the new Liquid Waste System Plan. The unit is a cylindrical disposal cell of 375 ft in diameter and 43 ft in height, and it has a minimum 30 million gallons of capacity. SRNL was requested to evaluate the impact of an increased grout placement height on the flow patterns radially spread on the floor and to determine whether grout quality is impacted by the height. The primary goals of the work are to develop the baseline Computational Fluid Dynamics (CFD) model and to perform the evaluations for the flow patterns of grout material in SDU6 as a function of elevation of grout discharge port and grout rheology. Two transient grout models have been developed by taking a three-dimensional multiphase CFD approach to estimate the domain size of the grout materials radially spread on the facility floor and to perform the sensitivity analysis with respect to the baseline design and operating conditions such as elevation height of the discharge port and fresh grout properties. For the CFD modeling calculations, air-grout Volume of Fluid (VOF) method combined with Bingham plastic and time-dependent grout models were used for examining the impact of fluid spread performance for the initial baseline configurations and to evaluate the impact of grout pouring height on grout quality. The grout quality was estimated in terms of the air volume fraction for the grout layer formed on the SDU6 floor, resulting in the change of grout density. The study results should be considered as preliminary scoping analyses since benchmarking analysis is not included in this task scope. Transient analyses with the Bingham plastic model were performed with the FLUENTTM code on the high performance parallel computing platform in SRNL. The analysis coupled with a transient grout aging model was performed by using ANSYS-CFX code

    Full Text Available Over half of China’s total energy consumption is attributed to rural buildings. However, unlike the research into urban areas, few studies have explored the problems of building energy efficiency (BEE in rural China. This study aims to establish an appropriate strategic plan for promoting rural BEE (RBEE in China by conducting a strength-weakness-opportunity-threat (SWOT analysis. Analysis data are obtained from multiple sources, including a comprehensive literature review, governmental reports, related regulations, and semi-structured interviews with a number of critical stakeholders. A matrix of the SWOT analysis is derived to reveal the drivers and barriers in the course of implementing RBEE. Five critical strategies are proposed. We also attempt to explore the internal and external conditions of RBEE in China, which can contribute to the customization and prioritization of policy recommendations for the Chinese government.

    In many European countries, external economic incentives are discussed as a policy instrument to promote occupational safety and health (OSH) in enterprises. This narrative case study review aims to support policy-makers in organizations providing such incentives by supplying information about different incentive schemes and their main characteristics such as effectiveness, efficiency, and feasibility. The focal point and topic centre network of the European Agency for Safety and Health at Work were used to collect case studies about incentive schemes aimed at supporting the prevention of occupational accidents and diseases in enterprises. Such incentives are rarely described in the scientific literature. To be considered for this review, studies had to focus on external financial benefits that could be provided as part of an insurance-related incentive or a governmental subsidy scheme. In total, 14 cases were included in the review: 6 insurance premium- and 8 subsidy-based schemes. Of these, 13 contained an evaluation of the incentive scheme, of which 7 use quantitative criteria. Three cases provided sufficient data to conduct a cost-benefit analysis. Most qualitative evaluations related to the successful management of the program and the effectiveness of the promoted measures in the workplace. Regarding the latter, quantitative criteria covered accident rates, sick leave, and general improvement in working conditions. The cost-benefit analyses all resulted in a positive payout ratio, ranging from 1.01-4.81 euros return for every 1 euro invested. Generally, we found economic incentive schemes to be feasible and reasonably effective. However, analysis regarding the efficiency of such schemes is scarce and our evaluation of the cost-benefit analysis had to rely on few cases that, nevertheless, delivered positive results for large samples. Besides this finding, our study also revealed deficits in the quality of evaluations. In order to enable policy-makers to make

    An ecological perspective to school readiness focuses on child and family readiness by enhancing the developmental contexts and relationships within which children reside (e.g., home environment, parent-child relationship, home-school relationships). The Getting Ready intervention is an ecological, relationally based, tiered intervention providing both universal and intensive services to children and families to promote child and family school readiness. Intensive level consultation services were provided via Conjoint Behavioral Consultation (CBC; Sheridan & Kratochwill, 1992 , 2008 ). The purpose of this article is to describe the implementation and effects of CBC within the Getting Ready intervention to promote child and family school readiness. Keys to successful implementation of the CBC intervention and issues needing further investigation are discussed.

  4. ATF6alpha promotes astroglial activation and neuronal survival in a chronic mouse model of Parkinson's disease.

    Directory of Open Access Journals (Sweden)

    Koji Hashida

    Full Text Available Accumulating evidence suggests a crucial role for the unfolded protein response (UPR in Parkinson's disease (PD. In this study, we investigated the relevance of the UPR in a mouse model of chronic MPTP/probenecid (MPTP/P injection, which causes severe and persistent degeneration of dopaminergic neurons. Enhanced activation of the UPR branches, including ATF6α and PERK/eIF2α/ATF4, was observed after MPTP/P injections into mice. Deletion of the ATF6α gene accelerated neuronal degeneration and ubiquitin accumulation relatively early in the MPTP/P injection course. Surprisingly, astroglial activation was strongly suppressed, and production of the brain-derived neurotrophic factor (BDNF and anti-oxidative genes, such as heme oxygenase-1 (HO-1 and xCT, in astrocytes were reduced in ATF6α -/- mice after MPTP/P injections. Decreased BDNF expression in ATF6α -/- mice was associated with decreased expression of GRP78, an ATF6α-dependent molecular chaperone in the ER. Decreased HO-1 and xCT levels were associated with decreased expression of the ATF4-dependent pro-apoptotic gene CHOP. Consistent with these results, administration of the UPR-activating reagent tangeretin (5,6,7,8,4'-pentamethoxyflavone; IN19 into mice enhanced the expression of UPR-target genes in both dopaminergic neurons and astrocytes, and promoted neuronal survival after MPTP/P injections. These results suggest that the UPR is activated in a mouse model of chronic MPTP/P injection, and contributes to the survival of nigrostriatal dopaminergic neurons, in part, through activated astrocytes.

The absorber is used in a large-scale ammonia plant to remove CO2 from the process gas stream. The CO2 is removed from the gas stream by counter-current absorption in two stages column. Lean solution and semi lean solution were fed into the top of upper part column and lower part column, respectively. To represent the gas-liquid system, a rigorous mathematical model based on the two-film theory is considered. The heat effects are taken into account. The model consists of differential mass and heat balance and considers the interactions between mass-transfer and chemical kinetics using enhancement factor concept. The chemical reaction in the liquid phase is based on the bicarbonate ion formation from CO2 as the rate-determining step. Gas solubility, mass and heat transfer coefficients, reaction kinetics and equilibrium were estimated using correlations from literatures.Therefore, multi-component absorption phenomena were considered in the mathematical model. The model was validated using plant data and was used to compute temperature and concentration profiles in the absorber. The variation in percent CO2 recovery with respect to changes in some operating variables is evaluated. The effect of various kinds of promoters added into potassium carbonate solution on the carbon dioxide recovery was also investigated.

    Osteoporosis is a systemic skeletal disorder characterized by reduction of one mass, deterioration of bone structure, increasing bone fragility, and increasing fracture risk. Prevention of osteoporosis during childhood and adolescence is one of the most important issues in World Health Organization. The purpose of this study was to determine the effect of Health Belief Model based intervention on promoting nutritional behaviors about preventive osteoporosis among the second grade middle school girl students. This was an experimental intervention study, the research population being 130 students who were randomly divided into groups, experimental (66) and control (64). Before the educational program, Health Belief Model based standard questionnaire and Food Frequency Questionnaire (FFQ) questionnaire were filled up by both the groups. The standard questionnaire was completed three times (before, immediately, and 2 months after education) and FFQ questionnaire was completed two times (before and 2 months after education) by the students. After pre-test, four educational session classes in the experimental group were performed. Finally, data collected were analyzed by SPSS 18 computer software. The result of this study showed a significant increase in the mean score of knowledge, perceived susceptibility, seriousness, benefits, barriers, as well as taking health action among girl students in the experimental group. The findings of the present study confirmed the practicability and effectiveness of the Health Belief Model based educational program in promoting nutritional behaviors about prevention of osteoporosis.

    Although some articles have analysed the definitions of health and health promotion from the perspective of health-care users and health care professionals, no published studies include the simultaneous participation of health-care users, primary health care professionals and key community informants. Understanding the perception of health and health promotion amongst these different stakeholders is crucial for the design and implementation of successful, equitable and sustainable measures that improve the health and wellbeing of populations. Furthermore, the identification of different health assets and deficits by the different informants will generate new evidence to promote healthy behaviours, improve community health and wellbeing and reduce preventable inequalities. The objective of this study is to explore the concept of health and health promotion and to compare health assets and deficits as identified by health-care users, key community informants and primary health care workers with the ultimate purpose to collect the necessary data for the design and implementation of a successful health promotion intervention. A descriptive-interpretive qualitative research was conducted with 276 participants from 14 primary care centres of 7 Spanish regions. Theoretical sampling was used for selection. We organized 11 discussion groups and 2 triangular groups with health-care users; 30 semi-structured interviews with key community informants; and 14 discussion groups with primary health care workers. A thematic content analysis was carried out. Health-care users and key community informants agree that health is a complex, broad, multifactorial concept that encompasses several interrelated dimensions (physical, psychological-emotional, social, occupational, intellectual, spiritual and environmental). The three participants' profiles consider health promotion indispensable despite defining it as complex and vague. In fact, most health-care users admit to having

    Full Text Available Hydrogen (H(2 acts as a therapeutic antioxidant. However, there are few reports on H(2 function in other capacities in diabetes mellitus (DM. Therefore, in this study, we investigated the role of H(2 in glucose transport by studying cultured mouse C2C12 cells and human hepatoma Hep-G2 cells in vitro, in addition to three types of diabetic mice [Streptozotocin (STZ-induced type 1 diabetic mice, high-fat diet-induced type 2 diabetic mice, and genetically diabetic db/db mice] in vivo. The results show that H(2 promoted 2-[(14C]-deoxy-d-glucose (2-DG uptake into C2C12 cells via the translocation of glucose transporter Glut4 through activation of phosphatidylinositol-3-OH kinase (PI3K, protein kinase C (PKC, and AMP-activated protein kinase (AMPK, although it did not stimulate the translocation of Glut2 in Hep G2 cells. H(2 significantly increased skeletal muscle membrane Glut4 expression and markedly improved glycemic control in STZ-induced type 1 diabetic mice after chronic intraperitoneal (i.p. and oral (p.o. administration. However, long-term p.o. administration of H(2 had least effect on the obese and non-insulin-dependent type 2 diabetes mouse models. Our study demonstrates that H(2 exerts metabolic effects similar to those of insulin and may be a novel therapeutic alternative to insulin in type 1 diabetes mellitus that can be administered orally.

    Soil is a habitat where plant roots and microorganisms interact. In the region of the Brazilian Iron Quadrangle (IQ), studies involving the interaction between microbiota and plants have been neglected. Even more neglected are the studies involving the holoparasite plant Langsdorffia hypogaea Mart. (Balanophoraceae). The geomorphological peculiarities of IQ soil, rich in iron ore, as well as the model of interaction between L. hypogaea, its hosts and the soil provide a unique niche that acts as selective pressure to the evolution of plant growth-promoting bacteria (PGPB). The aim of this study was to prospect the bacterial microbiota of holoparasitic plant L. hypogaea, its plant host and corresponding rhizosphere of IQ soil, and to analyze the potential of these isolates as PGPB. We obtained samples of 11 individuals of L. hypogaea containing fragments of host and rhizosphere remnants, resulting in 81 isolates associated with Firmicutes and Proteobacteria phyla. The ability to produce siderophores, hydrocyanic acid (HCN), indole-3-acetic acid (IAA), nitrogen (N2) fixation, hydrolytic enzymes secretion and inhibition of enteropathogens, and phytopathogens were evaluated. Of the total isolates, 62, 86, and 93% produced, respectively, siderophores, IAA, and were able to fix N2. In addition, 27 and 20% of isolates inhibited the growth of enteropathogens and phytopathogens, respectively, and 58% were able to produce at least one hydrolytic activity investigated. The high number of isolates that produce siderophores and indole-3-acetic acid suggests that this microbiota may be important for adaptation of plants to IQ. The results demonstrate for the first time the biological importance of Brazilian IQ species as reservoirs of specific microbiotas that might be used as PGPB on agricultural land or antropized soils that needs to be reforested.

    This study examined the relationships among behavior-specific cognitions and oral health behaviors using Pender's revised health promotion model. Subjects were 300 preuniversity students from 6 high schools in the Yazd district in central Iran. Suitable instruments were designed to measure concepts in the model through validity testing with an expert health panel, and reliability testing with a small sample of students (n = 30). Instruments then were administered to students. Model testing was conducted to identify factors affecting students' practice of oral health behaviors. The results from structural equation modeling indicated that behavior-specific cognitions and affect had a direct effect on oral health behaviors, except activity-related affects. Self-efficacy had an indirect effect on oral health behaviors through perceived barriers. Self-efficacy mediated the effects of behaviors-specific cognitions and affect on oral health behaviors. Together, the variables accounted for 32% of the variance in oral health behaviors. Results of this study can be used to design and evaluate interventions to promote oral health behaviors among students.

    Full Text Available Japanese encephalitis virus (JEV induces neuroinflammation with typical features of viral encephalitis, including inflammatory cell infiltration, activation of microglia, and neuronal degeneration. The detrimental effects of inflammation on neurogenesis have been reported in various models of acute and chronic inflammation. We investigated whether JEV-induced inflammation has similar adverse effects on neurogenesis and whether those effects can be reversed using an anti-inflammatory compound minocycline.Here, using in vitro studies and mouse models, we observed that an acute inflammatory milieu is created in the subventricular neurogenic niche following Japanese encephalitis (JE and a resultant impairment in neurogenesis occurs, which can be reversed with minocycline treatment. Immunohistological studies showed that proliferating cells were replenished and the population of migrating neuroblasts was restored in the niche following minocycline treatment. In vitro, we checked for the efficacy of minocycline as an anti-inflammatory compound and cytokine bead array showed that production of cyto/chemokines decreased in JEV-activated BV2 cells. Furthermore, mouse neurospheres grown in the conditioned media from JEV-activated microglia exhibit arrest in both proliferation and differentiation of the spheres compared to conditioned media from control microglia. These effects were completely reversed when conditioned media from JEV-activated and minocycline treated microglia was used.This study provides conclusive evidence that JEV-activated microglia and the resultant inflammatory molecules are anti-proliferative and anti-neurogenic for NSPCs growth and development, and therefore contribute to the viral neuropathogenesis. The role of minocycline in restoring neurogenesis may implicate enhanced neuronal repair and attenuation of the neuropsychiatric sequelae in JE survivors.

    Endothelial dysfunction assessed by brachial artery flow-mediated dilation (FMD) is a marker of early atherosclerosis. Glucocorticoid receptor gene (NR3C1) regulates many biological processes, including stress response, behavioral, cardiometabolic and immunologic functions. Genetic variants in NR3C1 have been associated with atherosclerosis and related risk factors. This study investigated the association of NR3C1 promoter methylation with FMD, independent of genetic and family-level environmental factors. We studied 84 middle-aged, male-male monozygotic twin pairs recruited from the Vietnam Era Twin Registry. Brachial artery FMD was measured by ultrasound. DNA methylation levels at 22 CpG residues in the NR3C1 exon 1F promoter region were quantified by bisulfite pyrosequencing in genomic DNA isolated from peripheral blood leukocytes. Co-twin control analyses were conducted to examine the association of methylation variation with FMD, adjusting for smoking, physical activity, body mass index, lipids, blood pressure, fasting glucose, and depressive symptoms. Multiple testing was corrected using the false discovery rate. Mean methylation level across the 22 studied CpG sites was 2.02%. Methylation alterations at 12 out of the 22 CpG residues were significantly associated with FMD. On average, a 1% increase in the intra-pair difference in mean DNA methylation was associated with 2.83% increase in the intra-pair difference in FMD (95% CI: 1.46-4.20; P atherosclerosis, independent of genetic, early family environmental and other risk factors.

    Results of previous studies attest to the greater illness burden of common mental disorders (anxiety and depression) in older Latinos and the need for developing preventive interventions that are effective, acceptable, and scalable. Happy Older Latinos are Active (HOLA) is a newly developed intervention that uses a community health worker (CHW) to lead a health promotion program in order to prevent common mental disorders among at-risk older Latinos. This pilot study tests the feasibility and acceptability of delivering HOLA to older, at-risk Latinos. HOLA is a multi-component, health promotion intervention funded by the National Institute of Mental Health (NIMH). This prevention approach will be tested against a fotonovela, an enhanced psychoeducation control condition, in a sample of Latino elderly with minor or subthreshold depression or anxiety. A total of 60 older Latinos (aged 60+) will be randomized to receive HOLA or the fotonovela. The primary outcomes of interest are recruitment, adherence, retention, and acceptability. Data will also be collected on: preemption of incident and recurrent major depression, generalized anxiety, and social phobia; reduction in depression and anxiety symptom severity; physical functioning; sedentary behaviors; social engagement; and self-efficacy. The results of this study could have implications for other high-risk, highly disadvantaged populations. The development of a health promotion intervention designed to prevent common mental disorders could be a means of addressing multiple disparities (for example, mental health outcomes, mental health service use, stigma) among racial/ethnic minority elderly.

    Fibril formation resulting from protein misfolding and aggregation is a hallmark of several neurodegenerative diseases such as Alzheimer’s and Parkinson’s diseases. Despite the fact that the fibril formation process is very slow and thus poses a significant challenge for theoretical and experimental studies, a number of alternative pictures of molecular mechanisms of amyloid fibril formation have been recently proposed. What seems to be common for the majority of the proposed models is that fibril elongation involves the formation of pre-nucleus seeds prior to the creation of a critical nucleus. Once the size of the pre-nucleus seed reaches the critical nucleus size, its thermal fluctuations are expected to be small and the resulting nucleus provides a template for sequential (one-by-one) accommodation of added monomers. The effect of template fluctuations on fibril formation rates has not been explored either experimentally or theoretically so far. In this paper, we make the first attempt at solving this problem by two sets of simulations. To mimic small template fluctuations, in one set, monomers of the preformed template are kept fixed, while in the other set they are allowed to fluctuate. The kinetics of addition of a new peptide onto the template is explored using all-atom simulations with explicit water and the GROMOS96 43a1 force field and simple lattice models. Our result demonstrates that preformed template fluctuations can modulate protein aggregation rates and pathways. The association of a nascent monomer with the template obeys the kinetics partitioning mechanism where the intermediate state occurs in a fraction of routes to the protofibril. It was shown that template immobility greatly increases the time of incorporating a new peptide into the preformed template compared to the fluctuating template case. This observation has also been confirmed by simulation using lattice models and may be invoked to understand the role of template fluctuations in

    Chronic wasting disease (CWD) is a fatal disease of deer, elk, and moose transmitted through direct, animal-to-animal contact, and indirectly, via environmental contamination. Considerable attention has been paid to modeling direct transmission, but despite the fact that CWD prions can remain infectious in the environment for years, relatively little information exists about the potential effects of indirect transmission on CWD dynamics. In the present study, we use simulation models to demonstrate how indirect transmission and the duration of environmental prion persistence may affect epidemics of CWD and populations of North American deer. Existing data from Colorado, Wyoming, and Wisconsin's CWD epidemics were used to define plausible short-term outcomes and associated parameter spaces. Resulting long-term outcomes range from relatively low disease prevalence and limited host-population decline to host-population collapse and extinction. Our models suggest that disease prevalence and the severity of population decline is driven by the duration that prions remain infectious in the environment. Despite relatively low epidemic growth rates, the basic reproductive number, R0, may be much larger than expected under the direct-transmission paradigm because the infectious period can vastly exceed the host's life span. High prion persistence is expected to lead to an increasing environmental pool of prions during the early phases (i.e. approximately during the first 50 years) of the epidemic. As a consequence, over this period of time, disease dynamics will become more heavily influenced by indirect transmission, which may explain some of the observed regional differences in age and sex-specific disease patterns. This suggests management interventions, such as culling or vaccination, will become increasingly less effective as CWD epidemics progress.

  20. Crystal study and econometric model

    1975-01-01

    An econometric model was developed that can be used to predict demand and supply figures for crystals over a time horizon roughly concurrent with that of NASA's Space Shuttle Program - that is, 1975 through 1990. The model includes an equation to predict the impact on investment in the crystal-growing industry. Actually, two models are presented. The first is a theoretical model which follows rather strictly the standard theoretical economic concepts involved in supply and demand analysis, and a modified version of the model was developed which, though not quite as theoretically sound, was testable utilizing existing data sources.

    NRF2 is a transcription factor that drives antioxidant gene expression in multiple organ systems. We hypothesized that Nrf2 overexpression could be therapeutically applied toward diseases in which redox homeostasis is disrupted. In this study, adeno-associated virus (AAV)-Nrf2 was tested in a mouse model of acute acetaminophen-induced liver toxicity and successfully conferred protection from hepatotoxicity, validating the vector design and early onset of NRF2-mediated protection. Furthermore, therapeutic potential of AAV-Nrf2 in chronic disease also was tested in a light-induced mouse model of age-related macular degeneration. Adult BALB/c mice were intravitreally injected with AAV-Nrf2 and subject to light damage following injection. Retinal thickness and function were monitored following light damage using optical coherence tomography and electroretinography, respectively. By 3 months post-damage, injected eyes had greater retinal thickness compared to uninjected controls. At 1 month post-damage, AAV-Nrf2 injection facilitated full functional recovery from light damage. Our results suggest a therapeutic potential for Nrf2 overexpression in acute and long-term capacities in multiple organ systems, opening up doors for combination gene therapy where replacement gene therapy requires additional therapeutic support to prevent further degeneration.

    S100A4, a calcium-binding protein, is known for its role in the metastatic spread of tumor cells, a late event of cancer disease. This is the first report showing that S100A4 is not merely a metastatic protein but also an oncoprotein that plays a critical role in the development of tumors. We...... earlier showed that S100A4 expression progressively increases in prostatic tissues with the advancement of prostate cancer (CaP) in TRAMP, an autochthonous mouse model. To study the functional significance of S100A4 in CaP, we generated a heterozygously deleted S100A4 (TRAMP/S100A4(+/-)) genotype...... weights (P cells and tested their potential. S100A4-positive tumors grew at a faster rate than S100A4-negative tumors in vitro and in a xenograft mouse model. The S100A4 protein exhibited growth factor-like properties in multimode...

    Enhancing clinical efficacy remains a major goal in allergen-specific immunotherapy. In this study, we tested three strains of bifidobacteria as candidate adjuvants for sublingual allergy vaccines. Probiotic candidates were evaluated in human monocyte-derived dendritic cell (h-DC) maturation and CD4(+) T-cell polarization in vitro models and further tested in murine models of sublingual immunotherapy in BALB/c mice sensitized to either ovalbumin or birch pollen. Bifidobacterium adolescentis, B. bifidum and B. longum induced h-DC maturation and polarized naïve CD4(+) T cells toward interferon-γ and interleukin-10 production. B. bifidum increased CD25(high), Foxp3(+) cells within CD4(+) T lymphocytes and was the most potent inducer of interferon-γ in Th2-skewed peripheral blood mononuclear cells and h-DC T-cell cocultures. It also induced a significant decrease in airway hyperresponsiveness in BALB/c mice sensitized to ovalbumin. Sublingual administration of B. bifidum together with recombinant Bet v 1 enhanced tolerance induction in BALB/c mice sensitized to birch pollen, with a downregulation of both airway hyperresponsiveness, lung inflammation and Bet v 1-specific Th2 responses. Due to its capacity to reorient established Th2 responses toward Th1/regulatory T-cell profiles, B. bifidum represents a valid candidate adjuvant for specific immunotherapy of type I allergies.

    The positive effects of physical activities during pregnancy are totally recognized but due to lack of knowledge and negative aspect toward it, physical activities decrease throughout the pregnancy period. To find the appropriate model to enhance physical activity during pregnancy, the education that are focused on health belief constructs about physical activity during pregnancy, were assessed. This was a semi-experimental study conducted on 90 pregnant women in their first trimester that were divided into two groups of control and intervention. After assessing health belief model (HBM) constructs and measuring the duration of severe/moderate-intensity) physical activity through a questionnaire, participants were divided into two groups of 45. The intervention group received education about physical activity based on HBM and the control group received dental health education. In the second trimester again, the constructs of HBM and the duration of physical activities were evaluated. Significant level was set at P health beliefs in pregnant women, but this increase does not reach the adequate level.

    Professionally facilitated web-based interventions for couples affected by an illness such as cancer are growing in popularity. Attrition rates for such online programs, however, are substantially higher than what is observed in face-to-face therapeutic contexts, and lower levels of participant engagement are associated with poorer outcomes. In the present investigation, a task analysis was employed to develop a model of engagement promotion
