    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

    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

    Entry region swirl promoters gain importance in industry because of its effectiveness in augmentation of mass and heat transfer augmentation. Design of equipment needs momentum transfer data along with mass or heat transfer data. Hence an experimental investigation was carried out with coaxially placed entry region spiral coil as turbulence promoters on momentum transfer in forced convection flow of electrolyte in circular conduits. Aqueous solution of sodium hydroxide and 0.01 M equimolal Ferri-ferro cyanide system was chosen for the study. The study covered parameters like effect of pitch of the coil, effect of length of the coil, diameter of the coil, diameter of the coil wire, diameter of the annular rod. The promoter is measured by limiting current technique using diffusion controlled electrochemical reactions. The study comprises of evaluation of momentum transfer rates at the outer wall of the electrochemical cell. Pressure drop measurements were also made to obtain the energy consumption pattern. Within the range of variables covered. The results are correlated by the momentum transfer similarity function. Momentum transfer coefficients were evaluated from measured limiting currents. Effect of each parameter was studied in terms of friction factor. A model was developed for momentum transfer. The experimental data on momentum transfer was modeled in terms of momentum transfer function and Reynolds number, geometric parameters.

    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.

  11. The Mouse Solitary Odorant Receptor Gene Promoters as Models for the Study of Odorant Receptor Gene Choice.

    Directory of Open Access Journals (Sweden)

    Andrea Degl'Innocenti

    Full Text Available In vertebrates, several anatomical regions located within the nasal cavity mediate olfaction. Among these, the main olfactory epithelium detects most conventional odorants. Olfactory sensory neurons, provided with cilia exposed to the air, detect volatile chemicals via an extremely large family of seven-transmembrane chemoreceptors named odorant receptors. Their genes are expressed in a monogenic and monoallelic fashion: a single allele of a single odorant receptor gene is transcribed in a given mature neuron, through a still uncharacterized molecular mechanism known as odorant receptor gene choice.Odorant receptor genes are typically arranged in genomic clusters, but a few are isolated (we call them solitary from the others within a region broader than 1 Mb upstream and downstream with respect to their transcript's coordinates. The study of clustered genes is problematic, because of redundancy and ambiguities in their regulatory elements: we propose to use the solitary genes as simplified models to understand odorant receptor gene choice.Here we define number and identity of the solitary genes in the mouse genome (C57BL/6J, and assess the conservation of the solitary status in some mammalian orthologs. Furthermore, we locate their putative promoters, predict their homeodomain binding sites (commonly present in the promoters of odorant receptor genes and compare candidate promoter sequences with those of wild-caught mice. We also provide expression data from histological sections.In the mouse genome there are eight intact solitary genes: Olfr19 (M12, Olfr49, Olfr266, Olfr267, Olfr370, Olfr371, Olfr466, Olfr1402; five are conserved as solitary in rat. These genes are all expressed in the main olfactory epithelium of three-day-old mice. The C57BL/6J candidate promoter of Olfr370 has considerably varied compared to its wild-type counterpart. Within the putative promoter for Olfr266 a homeodomain binding site is predicted. As a whole, our findings

    Full Text Available The present study proposes a group of factors (related to self, context and process favouring the development of intercultural sensitivity. A social diagnosis was performed in the Spanish province of Castellón in order to identify these factors by means of a correlational study. A non-probabilistic but representative sample consisting of 995 people from 37 different countries living in this province was used. Data were collected by means of an adaptation of the scale proposed by Chen and Starosta (2000 for the assessment of intercultural sensitivity. Results showed four profiles, and their main characteristics were studied. Variables such as country of origin, gender, academic background, number of languages spoken, or the experience of living in a foreign country revealed to have a positive influence on the development of this attitude. El presente artículo propone un conjunto de los factores (personales, contextuales y de proceso que favorecen el desarrollo de la sensibilidad intercultural. Para identificar dichos factores se ha realizado un diagnóstico social en la provincia de Castellón (España. Este estudio de tipo descriptivo de carácter correlacional se ha concretado con una muestra de 995 personas de 37 nacionalidades diferentes, constituyendo una muestra representativa, caracterizada por ser de tipo fortuito o accidental. Para recoger la información se ha utilizado una adaptación de la escala de sensibilidad intercultural de Chen y Starosta (2000. El análisis de datos ha permitido identificar cuatro perfiles, de los cuales se han estudiado sus principales características y se ha podido concluir que variables tales como la condición de origen, el sexo, la formación, la cantidad de lenguas que habla o el haber vivido en otro país influyen positivamente para el desarrollo de esta actitud.

    To describe the factors facilitating the implementation of heart health promotion programs for older adults in Anglican, United, and Catholic churches. The study used qualitative methods comprising semistructured interviews and focus groups. The interviews and focus groups were conducted in Anglican, Catholic, and United churches located in the Canadian cities of Toronto and Hamilton, Ontario. Twelve ordained pastors and 21 older parishioners who attended church regularly and who had no health conditions were recruited to best explain how churches could be suitable locations for health promotion activities targeting older adults. Twelve semistructured interviews with the pastors and three focus groups with the 21 parishioners were undertaken. A component of the Precede-Proceed model (a model for planning health education and health promotion programs and policies) was applied to the findings after direct content analysis of the data. Participants identified pastor leadership, funding for a parish nurse, community-focused interventions, secured infrastructure, and social support from congregation members as pertinent factors required for implementing health promotion programs in Anglican, United, and Catholic churches. The findings have particular relevance for health promotion and public health because they suggest factors that would be necessary to design church-based heart health promotion programs for older adults at risk of chronic diseases.

    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.

    As resources for health promotion become more constricted, it is increasingly important to collaborate across sectors, including the private sector. Although many excellent models for cross-sector collaboration have shown promise in the health field, collective impact (CI), an emerging model for creating larger scale change, has yet to receive much study. Complementing earlier collaboration approaches, CI has five core tenets: a shared agenda, shared measurement systems, mutually reinforcing activities, continuous communication, and a central infrastructure. In this article, we describe the CI model and its key dimensions and constructs. We briefly compare CI to community coalition action theory and discuss our use of the latter to provide needed detail as we apply CI in a critical case study analysis of the Tenderloin Healthy Corner Store Coalition in San Francisco, California. Using Yin's multimethod approach, we illustrate how CI strategies, augmented by the community coalition action theory, are being used, and with what successes or challenges, to help affect community- and policy-level change to reduce tobacco and alcohol advertising and sales, while improving healthy, affordable, and sustainable food access. We discuss the strengths and weaknesses of CI as a framework for health promotion, as well as the benefits, challenges, and initial outcomes of the healthy retail project and its opportunities for scale-up. Implications for health promotion practice and research also are discussed. © 2015 Society for Public Health Education.

    2018-02-01

    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

    Full Text Available 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%.

    The aim of this study was to describe the content of a multiyear market-based workplace health promotion (WHP) program and to evaluate design and implementation processes in a real-world setting. Data was collected from the databases of the employer and the service provider. It was classified using the 4-S (Size, Scope, Scalability, and Sustainability) and PIPE Impact Metric (Penetration, Implementation) models. Data analysis utilized both qualitative and quantitative methods. Program design covered well the evidence-informed best practices except for clear path toward sustainability, cooperation with occupational health care, and support from middle-management supervisors. The penetration rate among participants was high (99%) and majority (81%) of services were implemented as designed. Study findings indicate that WHP market would benefit the use of evidence-based design principles and tendentious decisions to anticipate a long-term implementation process already during the planning phase.

    To describe and analyse to what extent the goals of the education in promoting culturally competent nursing care have been achieved from a student perspective. As Sweden has transformed into a multicultural society over the past 50 years, there is a need to specify, at all levels of the nursing programme, transcultural concepts for the success of integration. A research-based didactic model was designed for the nursing programme at Malmö University and this was followed by investigations of its outcome. The study is a prospective cohort study with an outcome analysis. A descriptive research study with a longitudinal design was performed, with the focus on Swedish nursing students' experiences of transcultural nursing knowledge and their attitudes before and after implementation of the didactic model. The students evaluate highly their competence to meet demands of multicultural health and medical service. Additionally, their ability to recognise and understand the consequences of international migration on health also received a high mean. The study revealed the knowledge and experience acquired by Swedish students in transcultural nursing. The assumption was that a visible development of knowledge should occur during the three years of education. Interpreting the findings, such effectiveness can be found and hopefully the students will be able to give holistic nursing care based on a person's individual culture.

    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.

  16. 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.

    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

    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.

    2018-01-01

    Full Text Available Advertising and sales promotion are two important specific marketing communications tools. In this paper, Internet sales promotion is introduced into a differential advertising model and investigated quantitatively. The conditions for the existence and stability of periodic solutions are obtained. Flip bifurcation of periodic solution is investigated analytically. The results show that the sales promotion parameter can modify the stability of the differential advertising model and lead to chaos through flip bifurcation, the sales level will eventually be no less than a given value by adjusting the value of the sales promotion parameter, and the optimal sales promotion strategy can lead to maximum profit. Numerical results for periodic solutions, bifurcation diagrams, and the effects of sales promotion strategies, which are illustrated with an example, are in good agreement with the theoretical analysis. These results have certain significant theoretical and practical value in related markets.

    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.

    Full Text Available The competence of health protection and promotion are mentioned in various legislative documents that regulate areas of education and health policy. The researches on health conditions of Lithuania Country's population disclosed the deteriorating health status of the society, even of the children. It has also been found that the focus on health education is not adequate. The number of National and International health programmes have been realized and educational methodological tools prepared in Lithuania, however the insufficient attention to the health promotion models is been noticed. The objectiveof this article is to discuss the theoretical models used in health education field. The questions to be answered: what theoretical models are used in order to development competence of health protection and promotion? Who does employ particular models? What are the advantages of various models? What conceptions unite and characterize theoretical models? The analysis of scientific literature revealed the number of diverse health promotion model; however none of them is dominant. Some of the models focus on intrapersonal, others on interpersonal or community level but in general they can be distinguished as cognitive – behavioural models which are characterized by three main conceptions: 1 the healthy living is determined by the perceived health related knowledge: what is known and understood would influence the behaviour; 2 the knowledge in healthy living field is essential but insufficient condition for behaviour change; 3 the great influence to healthy living life style is done by perception, motivation, skills and habits as well as social environment. These are the components that are typical to all theoretical models and that reflect the hole of the conditions influencing healthy living.

    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.

Thirty-eight students from the second and third year of nursing education, and four nurses answered questionnaires with closed and open ended questions. In addition two of the nurses wrote diaries. Data were subjected to qualitative and quantitative analysis. Almost all participants reported that collaboration between nursing college and nursing practice had been beneficial. Most students and all nurses reported about valuable learning, increased understanding of research utilization, and improved quality of nursing care. Both students and RNs recommended the CMBP to be used in all clinical placements to support academic learning and increase research utilization in clinical practice. Despite study limitations the findings indicate that the CMBP has a potential to be a useful model for teaching RNs' and students EBP. However, further refinement of the model is needed, followed by a more comprehensive implementation and evaluation. Copyright © 2013 Elsevier Ltd. All rights reserved.

    Full Text Available It is known that there was strong relation between health status of primary school students and school records. A health­ promoting school was, whether all members of school community work together to provide students with an integrated positive experiences and structures which promote and protect their health.These include both formal and informal curriculum in health, creation of a safe and healthy school environment, provision of appropriate health services and involvement of family and wider commmunities was in efforts to promote health. The objectives of, this study is to develop a model of health promoting school at poor urban areas which included to measure student knowledge and attitude, nutrition intake, and role of school teacher in health promotion. A stratified mulitistage randomized pre-post test control groups design was used in this study. Duration of this study was 3 years (2001-2003 and the location at 9 primary schools (6 intervention schools and 3 control schools in Semarang, Surakarta, Denpasar municipalities and Kendal district. Results of this study showed that students knowledge and atitude toward health were improved significantly as well as nutrition intake at intervention groups. This improvement was caused by the role of school teachers in health promotion which was integrated in daily learning process. Based on this results a model of health promoting school has been developed. It recommends to implement this health promoting school model at wider areas and to provide school teachers completed with health promotion manuals.   Keywords: model, health promoting school

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

    Directory of Open Access Journals (Sweden)

    Kam-Yiu Lam

    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.

  19. In-vivo luminescence model for the study of tumor regression and regrowth following combination regimens with differentiation-promoting agents and photodynamic therapy

    2013-03-01

    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.

  20. Evaluations of health promoting schools: a review of nine studies.

    Mũkoma, Wanjirũ; Flisher, Alan J

    2004-09-01

    The concept of 'health promoting schools' has been embraced internationally as an effective way of promoting the health of children, adolescents, and the wider school community. It is only recently that attempts have been made to evaluate health promoting schools. This paper reviews evaluations of health promoting schools and draws useful evaluation methodology lessons. The review is confined to school-based interventions that are founded explicitly on the concept of the health promoting school and employ the concept beyond one school domain. We included nine evaluations in this review. Seven of these were published in the peer reviewed scientific literature. Two were unpublished reports. One study was a randomized controlled trial, while a quasi-experimental research design with comparison schools was used in three studies. With three exceptions, combinations of quantitative and qualitative data were collected. There was evidence that the health promoting school has some influence on various domains of health for the school community. It is also possible to integrate health promotion into the school curriculum and policies successfully. However, the evaluation of health promoting schools is complex. We discuss some of the methodological challenges of evaluating health promoting schools and make suggestions for improving future evaluations.

  1. Promotion time cure rate model with nonparametric form of covariate effects.

    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.

    2007-03-01

    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.

    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.

    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.

    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.

  13. The salutogenic model of health in health promotion research.

    Science.gov (United States)

    Mittelmark, Maurice B; Bull, Torill

    2013-06-01

    Despite health promotion's enthusiasm for the salutogenic model of health, researchers have paid little attention to Antonovsky's central ideas about the ease/dis-ease continuum, defined in terms of 'breakdown' (the severity of pain and functional limitations, and the degree medical care is called for, irrespective of specific diseases). Rather, salutogenesis research has a strong focus on how sense of coherence relates to a wide range of specific diseases and illness endpoints. We address two questions: Why has Antonovsky's health concept failed to stimulate research on breakdown, and how can the present emphasis on disease be complemented by an emphasis on positive well-being in the salutogenic model? We show that (i) the breakdown concept of health as specified by Antonovsky is circular in definition, (ii) it is not measured on the 'required' ease/dis-ease continuum, (iii) it is not measureable by any validated or reliability-tested assessment tool, and (iv) it has not so much been rejected by health promotion, as it has not been considered at all. We show that Antonovsky came to view breakdown as but one aspect of well-being. He was open to the idea of well-being as something more positive than the absence of pain, suffering and need for medical care. We suggest ways to move salutogenesis research in the direction of well-being in its positive sense.

    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.

    This is a report published on June, 1996, by promotion expert commission for radiation application of the Atomic Energy Commission. Japanese research and development in the fields of forming and application techniques of radiation beams using accelerator is at comparatively high level in the world, and it seems to be important for Japan not only to maintain these research and development level but also to contribute to creation of worldwide intelligent welfare due to scientific technology. In this report, some investigations are conducted on present state and future view of the radiation application study using accelerator, accelerator facility necessary to promote such application study and a procedure to execute its smooth application. However, objects of the study are not limited only for physical study on elementary particle and atomic nucleus, but expanded to photon, electron, positron, muon, proton, neutron, various inonic beams and RI beams for radiations, which are widely applied to industries such as materials science, material engineering, bio-and life-science, medical science, technical engineering, and so forth, and which will be expected for large contribution to development of these industries. The following items are discussed here; 1) present state and future view of radiation application study using accelerator, 2) Accelerator to be prepared and its executing method, and 3) Promotion method of the accelerator application study.

    2018-06-01

    Physical inactivity is a major public health issue and healthcare professionals are encouraged to promote physical activity during routine patient contacts in order to reduce non-communicable diseases and enhance individuals' quality of life. Little is known about physical activity promotion in physiotherapy practice in the UK. The aim of this study was to better understand physiotherapists' experience of physical activity promotion in clinical practice. A qualitative study was undertaken comprising 12 telephone interviews with participants using a quota sampling approach. The qualitative data was analysed using a thematic analysis approach and written up according to COREQ guidelines. Four themes were identified (1) Current physiotherapy practice (2) Barriers to, and facilitators of physical activity promotion, (3) Exercise or physical activity? and (4) Functional restoration versus general wellbeing. Physiotherapists use routine clinical contacts to discuss physical activity. However, brief interventions are not consistently used and no common framework to guide physical activity promotion was identified. Approaches appear to be inconsistent and informal and focus largely on short-term restoration of function rather than health promotion. There is scope to improve practice in line with current guidance to maximise potential impact on inactivity. Copyright © 2018 Elsevier Ltd. All rights reserved.

    Lockwood, Penelope; Marshall, Tara C; Sadler, Pamela

    2005-03-01

    In two studies, cross-cultural differences in reactions to positive and negative role models were examined. The authors predicted that individuals from collectivistic cultures, who have a stronger prevention orientation, would be most motivated by negative role models, who highlight a strategy of avoiding failure; individuals from individualistic cultures, who have a stronger promotion focus, would be most motivated by positive role models, who highlight a strategy of pursuing success. In Study 1, the authors examined participants' reported preferences for positive and negative role models. Asian Canadian participants reported finding negative models more motivating than did European Canadians; self-construals and regulatory focus mediated cultural differences in reactions to role models. In Study 2, the authors examined the impact of role models on the academic motivation of Asian Canadian and European Canadian participants. Asian Canadians were motivated only by a negative model, and European Canadians were motivated only by a positive model.

    Health maintenance and promotion are the fundamental prerequisites to community development. The best time for establishing healthy lifestyle habits is during adolescence. Due to importance of health promotion behaviors in adolescents, this study was conducted to investigate health-promoting behaviors and its associated factors among high school students in Rasht, Iran. A cross-sectional descriptive study was conducted on 424 students during the first semester of the year 2012. We employed the multistage sampling design to recruit from private and public high schools in Rasht, Iran. The data collection instrument was a self-report questionnaire consisting of two parts. The first part of instrument was consisted of demographic questionnaire and the second part was adolescent health promotion scale (AHPS) questionnaire. AHPS questionnaire was consisted of six dimensions (nutrition, social support, health responsibility, life appreciation, physical activity, and stress management) to measure health promoting lifestyles. Statistical analysis was performed by SPSS 16 software employing ANOVA (analysis of variance) test, t-test, Mann-Whitney, and the Kruskal-Wallis. The score of total Adolescent Health Promotion Scale were 3.58 ± 0.52 (possible range was 1-5). The highest score was in life appreciation dimension (3.99 ± 0.068) and the lowest score was in health responsibility dimension. Moreover, Significant associations were found between the adolescent health promotion Scale with age (P school grade (P health instructors, schoolteachers, and families must pay more attention to these students. Moreover, as most of lifelong healthy and unhealthy lifestyle habits are established during adolescence, developing effective health promotion and disease prevention strategies for adolescents seems crucial.

    2015-01-01

    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.

    Using the frameworks of transformational learning and situated learning theory, we developed a technology-enhanced professionalism curricular model to build a learning community aimed at promoting residents' self-reflection and self-awareness. The RAPR model had 4 components: (1) R ecognize : elicit awareness; (2) A ppreciate : question assumptions and take multiple perspectives; (3) P ractice : try new/changed perspectives; and (4) R eflect : articulate implications of transformed views on future actions. The authors explored the acceptability and practicality of the RAPR model in teaching professionalism in a residency setting, including how residents and faculty perceive the model, how well residents carry out the curricular activities, and whether these activities support transformational learning. A convenience sample of 52 postgraduate years 1 through 3 internal medicine residents participated in the 10-hour curriculum over 4 weeks. A constructivist approach guided the thematic analysis of residents' written reflections, which were a required curricular task. A total of 94% (49 of 52) of residents participated in 2 implementation periods (January and March 2015). Findings suggested that RAPR has the potential to foster professionalism transformation in 3 domains: (1) attitudinal, with participants reporting they viewed professionalism in a more positive light and felt more empathetic toward patients; (2) behavioral, with residents indicating their ability to listen to patients increased; and (3) cognitive, with residents indicating the discussions improved their ability to reflect, and this helped them create meaning from experiences. Our findings suggest that RAPR offers an acceptable and practical strategy to teach professionalism to residents.

    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.

    Highlights: · The type of turbulence promoters has a strong influence on the hydrodynamics. · The dispersion model is appropriate for expanded plastic turbulence promoters. · The dispersion model is appropriate for glass beads turbulence promoters. - Abstract: The hydrodynamic behaviour of electrochemical reactors with parallel plate electrodes is experimentally studied using the stimulus-response method either with an empty reactor or with different turbulence promoters. Theoretical results which are in accordance with the analytical and numerical resolution of the dispersion model for a closed system are compared with the classical relationships of the normalized outlet concentration for open systems and the validity range of the equations is discussed. The experimental results were well correlated with the dispersion model using glass beads or expanded plastic meshes as turbulence promoters, which have shown the most advantageous performance. The Peclet number was higher than 63. The dispersion coefficient was found to increase linearly with flow velocity in these cases.

    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 production (β = .359, p promotion. In addition, results of cross-level moderating effect analysis by HLM demonstrated that the effects of organizational health culture on three dimensions of

    Although many educational institutions allow students to resit exams, a recently proposed mathematical model suggests that this could lead to a dramatic reduction in study-time investment, especially in rational students. In the current study, we present a modification of this model in which we included some well-justified assumptions about learning and performance on multiple-choice tests, and we tested its predictions in two experiments in which participants were asked to invest fictional study time for a fictional exam. Consistent with our model, the prospect of a resit exam was found to promote lower investments of study time for a first exam and this effect was stronger for participants scoring higher on the cognitive reflection test. We also found that the negative effect of resit exams on study-time investment was attenuated when access to the resit was made uncertain by making it probabilistic or dependent on obtaining a minimal, non-passing grade for the first attempt. Taken together, these results suggest that offering students resit exams may compromise the achievement of learning goals, and they raise the more general implication that second chances promote risky behavior.

    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

    Full Text Available ObjectivesPhysical activity behavior begins to decline during adolescence and continues to decrease throughout young adulthood. This study aims to explain factors that influence physical activity behavior in a sample of female adolescents using a health promotion model framework.MethodsThis cross-sectional survey was used to explore physical activity behavior among a sample of female adolescents. Participants completed measures of physical activity, perceived self-efficacy, self-esteem, social support, perceived barriers, and perceived affect. Interactions among the variables were examined using path analysis within a covariance modeling framework.ResultsThe final model accounted for an R2 value of 0.52 for physical activity and offered a good model-data fit. The results indicated that physical activity was predicted by self-esteem (β=0.46, p<0.001, perceived self-efficacy (β=0.40, p<0.001, social support (β=0.24, p<0.001, perceived barriers (β=-0.19, p<0.001, and perceived affect (β=0.17, p<0.001.ConclusionsThe findings of this study showed that the health promotion model was useful to predict physical activity behavior among the Iranian female adolescents. Information related to the predictors of physical activity behavior will help researchers plan more tailored culturally relevant health promotion interventions for this population.

    Full Text Available Building Collaborative Health Promotion Partnerships: The Jackson Heart Study. Background: Building a collaborative health promotion partnership that effectively employs principles of community-based participatory research (CBPR involves many dimensions. To ensure that changes would be long-lasting, it is imperative that partnerships be configured to include groups of diverse community representatives who can develop a vision for long-term change. This project sought to enumerate processes used by the Jackson Heart Study (JHS Community Outreach Center (CORC to create strong, viable partnerships that produce lasting change. Methods: JHS CORC joined with community representatives to initiate programs that evolved into comprehensive strategies for addressing health disparities and the high prevalence of cardiovascular disease (CVD. This collaboration was made possible by first promoting an understanding of the need for combined effort, the desire to interact with other community partners, and the vision to establish an effective governance structure. Results: The partnership between JHS CORC and the community has empowered and inspired community members to provide leadership to other health promotion projects. Conclusion: Academic institutions must reach out to local community groups and together address local health issues that affect the community. When a community understands the need for change to respond to negative health conditions, formalizing this type of collaboration is a step in the right direction.

    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.

    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

    Breast cancer is an important public health problem on the grounds that it is frequently seen and it is a fatal disease. The objective of this systematic analysis is to indicate the effects of interventions performed by nurses by using the Health Belief Model (HBM) and Health Promotion Model (HPM) on the breast cancer early diagnosis behaviors and on the components of the Health Belief Model and Health Promotion Model. The reveiw was created in line with the Centre for Reviews and Dissemination guide dated 2009 (CRD) and developed by York University National Institute of Health Researches. Review was conducted by using PUBMED, OVID, EBSCO and COCHRANE databases. Six hundred seventy eight studies (PUBMED: 236, OVID: 162, EBSCO: 175, COCHRANE:105) were found in total at the end of the review. Abstracts and full texts of these six hundred seventy eight studies were evaluated in terms of inclusion and exclusion criteria and 9 studies were determined to meet the criteria. Samplings of the studies varied between ninety four and one thousand six hundred fifty five. It was detected in the studies that educations provided by taking the theories as basis became effective on the breast cancer early diagnosis behaviors. When the literature is examined, it is observed that the experimental researches which compare the concepts of Health Belief Model (HBM) and Health Promotion Model (HPM) preoperatively and postoperatively and show the effect of these concepts on education and are conducted by nurses are limited in number. Randomized controlled studies which compare HBM and HPM concepts preoperatively and postoperatively and show the efficiency of the interventions can be useful in evaluating the efficiency of the interventions.

    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.

    Full Text Available Previously, we demonstrated that allopregnanolone (APα promoted proliferation of rodent and human neural progenitor cells in vitro. Further, we demonstrated that APα promoted neurogenesis in the hippocampal subgranular zone (SGZ and reversed learning and memory deficits in the male triple transgenic mouse model of Alzheimer's (3xTgAD. In the current study, we determined the efficacy of APα to promote the survival of newly generated neural cells while simultaneously reducing Alzheimer's disease (AD pathology in the 3xTgAD male mouse model. Comparative analyses between three different APα treatment regimens indicated that APα administered 1/week for 6 months was maximally efficacious for simultaneous promotion of neurogenesis and survival of newly generated cells and reduction of AD pathology. We further investigated the efficacy of APα to impact Aβ burden. Treatment was initiated either prior to or post intraneuronal Aβ accumulation. Results indicated that APα administered 1/week for 6 months significantly increased survival of newly generated neurons and simultaneously reduced Aβ pathology with greatest efficacy in the pre-pathology treatment group. APα significantly reduced Aβ generation in hippocampus, cortex, and amygdala, which was paralleled by decreased expression of Aβ-binding-alcohol-dehydrogenase. In addition, APα significantly reduced microglia activation as indicated by reduced expression of OX42 while increasing CNPase, an oligodendrocyte myelin marker. Mechanistic analyses indicated that pre-pathology treatment with APα increased expression of liver-X-receptor, pregnane-X-receptor, and 3-hydroxy-3-methyl-glutaryl-CoA-reductase (HMG-CoA-R, three proteins that regulate cholesterol homeostasis and clearance from brain. Together these findings provide preclinical evidence for the optimal treatment regimen of APα to achieve efficacy as a disease modifying therapeutic to promote regeneration while simultaneously decreasing

    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.

    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.

    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. 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. 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. 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. The influence of organizations on agenda setting is

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. The influence

    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.

    2017-10-01

    While cigarette pack designs are part of integrated marketing efforts, it is unclear the degree to which packs are used to advertise promotions and whether the tobacco retailers' neighborhood characteristics influence the likelihood and type of pack-based promotion in the United States. Between June and October 2012, data collectors purchased packs of either Marlboro Red (n = 1090) or Newport Green (n = 1057) cigarettes at 2147 stores that were part of a national sample of tobacco retailers in the contiguous US. Coders rated packs for the presence of an exterior and interior pack promotion, placement of exterior promotion (eg, front, back), presentation of exterior promotion (eg, onsert, tear strip), and nature of the promotion (eg, contest/give/away). Using Census tract data, we examined the association of pack promotions with tobacco retailers' neighborhood demographic characteristics. Marlboro packs were approximately twice as likely to have promotions as Newport packs (31.7% vs. 14.7%). Fewer Marlboro packs (14.6%) and no Newport packs had interior promotions. The majority of exterior promotions were for contests (>80% for both brands), while almost all interior Marlboro promotions (97.5%) were for a discounted price. There were few differences in presence or type of promotion by tobacco retailers' neighborhood characteristics. Exterior packs promotions, in particular, were fairly common and may contribute to the allure of tobacco products. Use of promotions on the interior and exterior of cigarette packs are a mechanism that the tobacco industry uses to sell its products and should be continually assessed for their influence on consumer behavior. © The Author 2016.

    Building nurses' resilience to complex and stressful practice environments is necessary to keep skilled nurses in the workplace and ensuring safe patient care. A unified theoretical framework titled Health Services Workplace Environmental Resilience Model (HSWERM), is presented to explain the environmental factors in the workplace that promote nurses' resilience. The framework builds on a previously-published theoretical model of individual resilience, which identified the key constructs of psychological resilience as self-efficacy, coping and mindfulness, but did not examine environmental factors in the workplace that promote nurses' resilience. This unified theoretical framework was developed using a literary synthesis drawing on data from international studies and literature reviews on the nursing workforce in hospitals. The most frequent workplace environmental factors were identified, extracted and clustered in alignment with key constructs for psychological resilience. Six major organizational concepts emerged that related to a positive resilience-building workplace and formed the foundation of the theoretical model. Three concepts related to nursing staff support (professional, practice, personal) and three related to nursing staff development (professional, practice, personal) within the workplace environment. The unified theoretical model incorporates these concepts within the workplace context, linking to the nurse, and then impacting on personal resilience and workplace outcomes, and its use has the potential to increase staff retention and quality of patient care.

    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.

    Objective: To combine the radio-inducible CArG element with cancer-specific human telomerase reverse transcriptase (hTERT) gene promoter, and to construct the novel chimeric promoters. Methods: The synthetic hTERT promoters containing different number of radio-inducible CArG elements were constructed, and the activities of the promoters in the cancer cells (HeLa, A549, and MHCC97 cells) and nomal cells (hEL cells) were detected by using luciferase-reporter assays after the treatment of irradiation (a single or fractionated irradiation dose). Results: Synthetic promoter containing 6 repeated CArG units was better in radio-inducibility than any other promoters containing different number of CArG units, and nearly maximum levels obtained at 4-6 Gy. The very low activities of the chimeric promoters could be detected in normal hEL cells. A similar level of reporter gene expression was observed after 3 fractionated doses of 2 Gy compared with a single dose of 6 Gy in cancer cells. Conclusions: The cancer-specific chimeric promoter containing 6 CArG elements showes the best radio-response, and the chimeric promoter system has the potential in cancer gene therapy. (authors)

    A virtual pet was developed based on the framework of the youth physical activity promotion model and tested as a vehicle for promoting physical activity in children. Children in the treatment group interacted with the virtual pet for three days, setting physical activity goals and teaching tricks to the virtual pet when their goals were met. The virtual pet became more fit and learned more sophisticated tricks as the children achieved activity goals. Children in the control group interacted with a computer system presenting equivalent features but without the virtual pet. Physical activity and goal attainment were evaluated using activity monitors. Results indicated that children in the treatment group engaged in 1.09 more hours of daily physical activity (156% more) than did those in the control group. Physical activity self-efficacy and beliefs served as mediators driving this increase in activity. Children that interacted with the virtual pet also expressed higher intentions than children in the control group to continue physical activity in the future. Theoretical and practical potentials of using a virtual pet to systematically promote physical activity in children are discussed.

    Research highlights: {yields} Compressive elastic stresses up to 250 MPa are applied in continuous cooling. {yields} Using the thermodynamic data and maximum value of the mechanical driving force the predicted increase in M{sub s} ({approx}0.1 K/MPa) is in agreement with experiment {yields} Austenite was deformed plastically at different temperatures (800 deg. C-1100 deg. C). {yields} High deformation temperature (i.e. 1100 deg. C) as well as low plastic strain (i.e. {epsilon}{sub ave} {approx} 30%) do not affect martensite transformation noticeably, whereas lower deformation temperature (e.g. 900 deg. C) and large plastic strain (i.e. {epsilon}{sub ave} {approx} 70%) retards martensite transformation. {yields} The theory of mechanical stabilization predicts the depression of M{sub s}. - Abstract: The influence of compressive stress and prior plastic deformation of austenite on the martensite transformation in a eutectoid steel is studied both experimentally and theoretically. It is demonstrated that martensite formation is assisted by stress but it is retarded when transformation occurs from deformed austenite. With the quantitative modeling of the problem based on the theory of displacive shear transformation, the explanation of the two opposite roles of mechanical treatment prior to or simultaneously to martensite transformation is presented.

    The connection between obesity and accelerated cancer progression has been established, but the mediating mechanisms are not well understood. We have shown that stromal cells from white adipose tissue (WAT) cooperate with the endothelium to promote blood vessel formation through the secretion of soluble trophic factors. Here, we hypothesize that WAT directly mediates cancer progression by serving as a source of cells that migrate to tumors and promote neovascularization. To test this hypothesis, we have evaluated the recruitment of WAT-derived cells by tumors and the effect of their engraftment on tumor growth by integrating a transgenic mouse strain engineered for expansion of traceable cells with established allograft and xenograft cancer models. Our studies show that entry of adipose stromal and endothelial cells into systemic circulation leads to their homing to and engraftment into tumor stroma and vasculature, respectively. We show that recruitment of adipose stromal cells by tumors is sufficient to promote tumor growth. Finally, we show that migration of stromal and vascular progenitor cells from WAT grafts to tumors is also associated with acceleration of cancer progression. These results provide a biological insight for the clinical association between obesity and cancer, thus outlining potential avenues for preventive and therapeutic strategies. PMID:19491274

    Selective memorising of isolated facts or reproducing what is thought to be required - the surface approach to learning - is not the desired outcome for a dental student or a dentist in practice. The preferred outcome is a deep approach as defined by an intention to seek understanding, develop expertise and relate information and knowledge into a coherent whole. The aim of this study was to investigate whether the structure of observed learning outcome (SOLO) taxonomy could be used as a model to assist and promote the dental students to develop a deep approach to learning assessed as learning outcomes in a summative assessment. Thirty-two students, participating in course eight in 2007 at the Faculty of Odontology at Malmö University, were introduced to the SOLO taxonomy and constituted the test group. The control group consisted of 35 students participating in course eight in 2006. The effect of the introduction was measured by evaluating responses to a question in the summative assessment by using the SOLO taxonomy. The evaluators consisted of two teachers who performed the assessment of learning outcomes independently and separately on the coded material. The SOLO taxonomy as a model for learning was found to improve the quality of learning. Compared to the control group significantly more strings and structured relations between these strings were present in the test group after the SOLO taxonomy had been introduced (P SOLO taxonomy is recommended as a model for promoting and developing a deeper approach to learning in dentistry.

    2012-01-01

    Wiki systems form a subclass of the more general Open Collaborative Authoring Systems, where content is created by a user community. The ability of anyone to edit the content is, at the same time, their strength and their weakness. Anyone can write documents that improve the value of the wiki-system......, but this also means that anyone can introduce errors into documents, either by accident or on purpose. A security model for wiki-style authoring systems, called the Secure Wiki Model, has previously been proposed to address this problem. This model is designed to prevent corruption of good quality documents......, by limiting updates, to such documents, to users who have demonstrated their ability to produce documents of similar or better quality. While this security model prevents all user from editing all documents, it does respect the wiki philosophy by allowing any author who has produced documents of a certain...

    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.

    This study aimed to develop Critical-Inquiry-Based-Learning (CIBL) learning model to promote critical thinking (CT) ability of preservice teachers. The CIBL learning model was developed by meeting the criteria of validity, practicality, and effectiveness. Validation of the model involves 4 expert validators through the mechanism of the focus group discussion (FGD). CIBL learning model declared valid to promote CT ability, with the validity level (Va) of 4.20 and reliability (r) of 90,1% (very reliable). The practicality of the model was evaluated when it was implemented that involving 17 of preservice teachers. The CIBL learning model had been declared practice, its measuring from learning feasibility (LF) with very good criteria (LF-score = 4.75). The effectiveness of the model was evaluated from the improvement CT ability after the implementation of the model. CT ability were evaluated using the scoring technique adapted from Ennis-Weir Critical Thinking Essay Test. The average score of CT ability on pretest is - 1.53 (uncritical criteria), whereas on posttest is 8.76 (critical criteria), with N-gain score of 0.76 (high criteria). Based on the results of this study, it can be concluded that developed CIBL learning model is feasible to promote CT ability of preservice teachers.

  15. Photoaffinity Labeling Studies on a Promoter of Dendritic Spine Formation

    Science.gov (United States)

    Sibucao, Kevin Carlo Abril

    The small molecule BTA-EG4 has been shown to be a promoter of dendritic spine formation. The mechanism behind this phenomenon, however, is not well understood. The work in this dissertation is motivated by this gap in knowledge. The first part of this dissertation focuses on photoaffinity labeling studies to identify the cellular targets of BTA-EG4. Chapter 1 provides a summary of Alzheimer's disease, the rational design of BTA-EG 4, and methods to determine targets of small molecules. In Chapter 2, the synthesis of a BTA-EG4-based photoaffinity labeling probe and photodegradation studies are presented. Kinetic studies demonstrate that the probe photolyzes rapidly under UV light. In Chapter 3, photoaffinity labeling studies and subsequent protein identification experiments are reported. Competition experiments with the photoaffinity labeling probe and BTA-EG4 demonstrate that the probe labels a 55-kDa protein specifically. Tandem mass spectrometry revealed that the 55-kDa protein is the actin binding protein fascin 1. The second part of this dissertation focuses on the major protein identified from photoaffinity labeling studies, fascin 1. Chapter 4 provides a brief survey of the structure and function of fascin 1. In Chapter 5, characterizations of the interaction between BTA-EG4 and fascin 1 are reported. Isothermal titration calorimetry confirms the physical binding between fascin 1 and BTA-EG6, a BTA-EG4 analog. Slow speed sedimentation assays reveal that BTA-EG4 does not affect the actin-bundling activity of fascin 1. However, GST pull-down experiments show that BTA-EG4 inhibits the binding of fascin 1 with the GTPase Rab35. In addition, this work demonstrates that BTA-EG4 may be mechanistically distinct from the known fascin inhibitor G2.

    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.

    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.

    Modern workplace health promotion (WHP) requires collaboration, partnerships, and alliances with both internal and external stakeholders. However, the identification of the key stakeholders as well as the systematic mapping of their views has barely been covered in the existing research literature. This article describes the stakeholders and stakeholder positions in WHP in Finland. In this study, the stakeholders were classified as internal, interface, and external stakeholders. Furthermore, based on the authors' research, stakeholders and their positions were represented on a stakeholder map as well as by the power-interest matrix of the stakeholders. The governmental authorities play a key role in driving the strategic change toward WHP by preparing the required legislation and regulatory measures. However, both active employers and active employees can through their own work accelerate the development of new WHP services. Close collaboration between employers and employees is required at the individual workplaces. Some stakeholders, such as pension funds and occupational health services (OHS) providers, can act as important driving forces and support the strategic implementation of WHP in the workplaces. However, alone they have only limited opportunities to organize the WHP activities. Understanding the various stakeholders and the systematic mapping of their positions is essential for the successful planning and implementation of WHP activities.

    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.

    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.

    On the 10th anniversary of Health Canada and the Association of Faculties of Medicine of Canada's publication in 2001 of Social Accountability: A Vision for Canadian Medical Schools, the authors review the progress at one Canadian medical school, the College of Medicine at the University of Saskatchewan, in developing a culture of social accountability. They review the changes that have made the medical school more socially accountable and the steps taken to make those changes possible. In response to calls for socially accountable medical schools, the College of Medicine created a Social Accountability Committee to oversee the integration of these principles into the college. The committee developed the CARE model (Clinical activity, Advocacy, Research, Education and training) as a guiding tool for social accountability initiatives toward priority health concerns and as a means of evaluation. Diverse faculty and student committees have emerged as a result and have had far-reaching impacts on the college and communities: from changes in curricula and admissions to community programming and international educational experiences. Although a systematic assessment of the CARE model is needed, early evidence shows that the most significant effects can be found in the cultural shift in the college, most notably among students. The CARE model may serve as an important example for other educational institutions in the development of health practitioners and research that is responsive to the needs of their communities.

    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.

    Testing the applicability of mathematical models with carefully designed experiments is a powerful tool in the investigations of the effects of ionizing radiation on cells. The modeling and cellular studies complement each other, for modeling provides guidance for designing critical experiments which must provide definitive results, while the experiments themselves provide new input to the model. Based on previous experimental results the model for the accumulation of damage in Chlamydomonas reinhardi has been extended to include various multiple two-event combinations. Split dose survival experiments have shown that models tested to date predict most but not all the observed behavior. Stationary-phase mammalian cells, required for tests of other aspects of the model, have been shown to be at different points in the cell cycle depending on how they were forced to stop proliferating. These cultures also demonstrate different capacities for repair of sublethal radiation damage

    Full Text Available Abstract Background For health promotion to be effective in Aboriginal and Torres Strait Islander Communities, interventions (and their evaluation need to work within a complex social environment and respect Indigenous knowledge, culture and social systems. At present, there is a lack of culturally appropriate evaluation methods available to practitioners that are capable of capturing this complexity. As an initial response to this problem, we used two non-invasive methods to evaluate a community-directed health promotion program, which aimed to improve nutrition and physical activity for members of the Aboriginal community of the Goulburn-Murray region of northern Victoria, Australia. The study addressed two main questions. First, for members of an Aboriginal sporting club, what changes were made to the nutrition environment in which they meet and how is this related to national guidelines for minimising the risk of chronic disease? Second, to what degree was the overall health promotion program aligned with an ecological model of health promotion that addresses physical, social and policy environments as well as individual knowledge and behaviour? Methods Rather than monitoring individual outcomes, evaluation methods reported on here assessed change in the nutrition environment (sports club food supply as a facilitator of dietary change and the 'ecological' nature of the overall program (that is, its complexity with respect to numbers of targets, settings and strategies. Results There were favourable changes towards the provision of a food supply consistent with Australian guidelines at the sports club. The ecological analysis indicated that the design and implementation of the program were consistent with an ecological model of health promotion. Conclusions The evaluation was useful for assessing the impact of the program on the nutrition environment and for understanding the ecological nature of program activities.

    Any defect in extremities of the body can affect different life aspects. The purpose of this study was to investigate the effect of Roy's adaptation model-guided education on promoting the adaptation of veterans with lower extremities amputation. In a randomized clinical trial, 60 veterans with lower extremities amputation referring to Kowsar Orthotics and Prosthetics Center of veterans clinic in Tehran, Iran, were recruited with convenience method and were randomly assigned to intervention and control groups during 2013 - 2014. For data collection, Roy's adaptation model questionnaire was used. After completing the questionnaires in both groups, maladaptive behaviors were determined in the intervention group and an education program based on Roy's adaptation model was implemented. After two months, both groups completed the questionnaires again. Data was analyzed with SPSS software. Independent t-test showed statistically significant differences between the two groups in the post-test stage in terms of the total score of adaptation (P = 0.001) as well as physiologic (P = 0.0001) and role function modes (P = 0.004). The total score of adaptation (139.43 ± 5.45 to 127.54 ± 14.55, P = 0.006) as well as the scores of physiologic (60.26 ± 5.45 to 53.73 ± 7.79, P = 0.001) and role function (20.30 ± 2.42 to 18.13 ± 3.18, P = 0.01) modes in the intervention group significantly increased, whereas the scores of self-concept (42.10 ± 4.71 to 39.40 ± 5.67, P = 0.21) and interdependence (16.76 ± 2.22 to 16.30 ± 2.57, P = 0.44) modes in the two stages did not have a significant difference. Findings of this research indicated that the Roy's adaptation model-guided education promoted the adaptation level of physiologic and role function modes in veterans with lower extremities amputation. However, this intervention could not promote adaptation in self-concept and interdependence modes. More intervention is advised based on Roy's adaptation model for improving the

    Background 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. Objective 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. Design 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. Results 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. Conclusions 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

    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

    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.

    Gene regulatory interactions underlying the early stages of non-genotoxic carcinogenesis are poorly understood. Here, we have identified key candidate regulators of phenobarbital (PB)-mediated mouse liver tumorigenesis, a well-characterized model of non-genotoxic carcinogenesis, by applying a new computational modeling approach to a comprehensive collection of in vivo gene expression studies. We have combined our previously developed motif activity response analysis (MARA), which models gene expression patterns in terms of computationally predicted transcription factor binding sites with singular value decomposition (SVD) of the inferred motif activities, to disentangle the roles that different transcriptional regulators play in specific biological pathways of tumor promotion. Furthermore, transgenic mouse models enabled us to identify which of these regulatory activities was downstream of constitutive androstane receptor and β-catenin signaling, both crucial components of PB-mediated liver tumorigenesis. We propose novel roles for E2F and ZFP161 in PB-mediated hepatocyte proliferation and suggest that PB-mediated suppression of ESR1 activity contributes to the development of a tumor-prone environment. Our study shows that combining MARA with SVD allows for automated identification of independent transcription regulatory programs within a complex in vivo tissue environment and provides novel mechanistic insights into PB-mediated hepatocarcinogenesis.

    While the US population overall has experienced improvements in oral health over the past 60 years, oral diseases remain among the most common chronic conditions across the life course. Further, lack of access to oral health care contributes to profound and enduring oral health inequities worldwide. Vulnerable and underserved populations who commonly lack access to oral health care include racial/ethnic minority older adults living in urban environments. The aim of this study was to use a systematic approach to explicate cause and effect relationships in creating a causal map, a type of concept map in which the links between nodes represent causality or influence. To improve our mental models of the real world and devise strategies to promote oral health equity, methods including system dynamics, agent-based modeling, geographic information science, and social network simulation have been leveraged by the research team. The practice of systems science modeling is situated amidst an ongoing modeling process of observing the real world, formulating mental models of how it works, setting decision rules to guide behavior, and from these heuristics, making decisions that in turn affect the state of the real world. Qualitative data were obtained from focus groups conducted with community-dwelling older adults who self-identify as African American, Dominican, or Puerto Rican to elicit their lived experiences in accessing oral health care in their northern Manhattan neighborhoods. The findings of this study support the multi-dimensional and multi-level perspective of access to oral health care and affirm a theorized discrepancy in fit between available dental providers and patients. The lack of information about oral health at the community level may be compromising the use and quality of oral health care among racial/ethnic minority older adults. Well-informed community members may fill critical roles in oral health promotion, as they are viewed as highly credible

    Full Text Available Modern lines in the field of transport management are directed on transition from analytical systems of processing of information to the information-operating systems providing support of decision-making in management by transportations. New conditions of managing, on the one hand, and development of the automated systems of gathering and processing of information in transport industry, on the other hand, allows to reach essentially new level of planning the parameters of transport operation with development of new methodology of solution of the given problems. The creation of dynamic model of promotion of traffic volumes is one of the new methods that allows solving a number of operational problems.. In the paper the mathematical description of range of a network and dynamic model is given. The concept of individual transportation is presented, classification of dynamic models depending on the initial information is given. Mathematical study and algorithm of construction of dynamic models enables their applications for solution of wide range of problems on transport.

  4. A multi-scale model of hepcidin promoter regulation reveals factors controlling systemic iron homeostasis.

    Directory of Open Access Journals (Sweden)

    Guillem Casanovas

    2014-01-01

    Full Text Available 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.

    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

    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. 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. 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. 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.

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.

    Priority setting is an important component of systematic planning in health promotion and also factors into the development of a comprehensive evaluation plan. The basic priority rating (BPR) model was introduced more than 50 years ago and includes criteria that should be considered in any priority setting approach (i.e., use of predetermined criteria, standardized comparisons, and a rubric that controls bias). Although the BPR model has provided basic direction in priority setting, it does not represent the broad array of data currently available to decision makers. Elements in the model also give more weight to the impact of communicable diseases compared with chronic diseases. For these reasons, several modifications are recommended to improve the BPR model and to better assist health promotion practitioners in the priority setting process. The authors also suggest a new name, BPR 2.0, to represent this revised model.

    The coal utilization is expected to make substantial growth according to the long-term energy supply/demand plan. To further expand the future coal utilization, however, it is indispensable to reduce environmental loads in its total use with other energies, based on the coal use. In this survey, a regional model survey was conducted as environmental load reduction measures using highly cleaned coal which were taken in fiscal 1993 and 1994. Concretely, a model system was assumed which combined facilities for mixed combustion with coal and other energy (hull, bagasse, waste, etc.) and facilities for effective use of burned ash, and potential reduction in environmental loads of the model system was studied. The technology of mixed combustion between coal and other energy is still in a developmental stage with no novelties in the country. Therefore, the mixed combustion technology between coal and other energy is an important field which is very useful for the future energy supply/demand and environmental issues. 34 refs., 27 figs., 48 tabs.

  11. A model to explain plant growth promotion traits: a multivariate analysis of 2,211 bacterial isolates.

    Directory of Open Access Journals (Sweden)

    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

    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.

    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.

    An important part in the effort to prevent, treat, and cure breast cancer is research done with healthy breast tissue. The Susan G. Komen for the Cure Tissue Bank at Indiana University Simon Cancer Center (KTB) encourages women to donate a small amount of healthy breast tissue and then provides that tissue to researchers studying breast cancer. Although KTB has a large donor base, the volume of tissue samples from Asian women is low despite prior marketing efforts to encourage donation among this population. This study builds on prior work promoting breast cancer screenings among Asian women by applying constructs from the Health Belief Model (HBM) and the Integrated Behavioral Model (IBM) to investigate why Asian-American women are less inclined to donate their healthy breast tissue than non-Asian women and how this population may be motivated to donate in the future. A national online survey (N = 1,317) found Asian women had significantly lower perceived severity, some lower perceived benefits, and higher perceived barriers to tissue donation than non-Asian women under HBM and significantly lower injunctive norms supporting breast tissue donation, lower perceived behavioral control, and lower intentions to donate under IBM. This study also compares and discusses similarities and differences among East, Southeast, and South Asian women on these same constructs.

    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

    Full Text Available With the support of a smart grid, a load aggregator (LA that aggregates the demand response resources of small- and medium-sized customers to participate in the electricity market would be a novel way to promote wind power accommodation. This paper proposes a wind farm–LA coordinated operation mode (WLCOM, which enables LAs to deal with wind farms directly at an agreement price. Afterwards, according to the accommodation demand of the wind farm, a coordinated dispatch model taking advantage of the various response capabilities of different flexible loads is set up to maximize the revenue of the LA. A case study was conducted to demonstrate the effectiveness of the proposed WLCOM and the coordinated dispatch model. The demonstration indicates that: (a load fluctuations and wind curtailment were obviously reduced; and (b both the LA and the wind farm participating in coordinated operation obtained higher revenues. Factors that influence the accommodation level, as well as revenues of wind farms and LA, are also investigated.

  2. The disconnected values (intervention) model for promoting healthy habits in religious institutions.

    Anshel, Mark H

    2010-03-01

    The purpose of this article is to provide an intervention model that can be used by religious leaders for changing health behavior among practicing members of religious communities. The intervention does not require extensive training or licensure in counseling psychology. At the heart of this model is the acknowledgement that a person's negative habits (e.g., lack of exercise, poor nutrition) and his or her deepest values and beliefs (e.g., faith, health, family) are often misaligned, or disconnected. In addition, the unhealthy outcomes from these habits are contrary to the scriptural traditions of the world religions and thus are especially relevant to individuals who practice their religious beliefs. The Sacred Scriptures of Judaism and Christianity, for example, are replete with teachings that extol the virtues of practicing habits that promote good health and energy. In addition, evidence is mounting in the existing health intervention literature that adopting permanent and desirable changes in health behavior have not been successful, and that adherence to desirable habits such as exercise and proper nutrition is short-lived. The Disconnected Values Model (DVM) provides a novel approach for enhancing health behavior change within the context of the mission of most religious institutions. The model is compatible with skills presented by religious leaders, who possess more credibility and influence in changing the behavior of members and service attendees of their respective religious institutions. The religious leader's role is to provide the client with faith-based incentives to initiate and maintain changes in their health behaviors, and perhaps to provide resources for the individual to pursue an action plan. A case study is described in which the DVM intervention was used successfully with an individual of strong faith.

    2013-01-01

    Luciferase based assays have become an invaluable tool for the analysis of cloned promoter DNA fragments, both for verifying the ability of a potential promoter fragment to drive the expression of a luciferase reporter gene in various cellular contexts, and for dissecting binding elements in the promoter. Here, we describe the use of the Dual-Luciferase(®) Reporter Assay System created by Promega (Promega Corporation, Wisconsin, USA) to study the cloned 6.7 kilobases (kb) mouse (m) Tcf3 promoter DNA fragment in mouse embryonic derived neural stem cells (NSC). In this system, the expression of the firefly luciferase driven by the cloned mTcf3 promoter DNA fragment (including transcription initiation sites) is correlated with a co-transfected control reporter expressing Renilla luciferase from the herpes simplex virus (HSV) thymidine kinase promoter. Using an internal control reporter allows to normalize the activity of the experimental reporter to the internal control, which minimizes experimental variability.

    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.

    Developing Information and Communication Technology (ICT) supported health communication in PHC could contribute to increased health literacy and empowerment, which are foundations for enabling people to increase control over their health, as a way to reduce increasing lifestyle related ill health. However, to increase the likelihood of success of implementing ICT supported health communication, it is essential to conduct a detailed analysis of the setting and context prior to the intervention. The aim of this study was to gain a better understanding of health communication for health promotion in PHC with emphasis on the implications for a planned ICT supported interactive health channel. A qualitative case study, with a multi-methods approach was applied. Field notes, document study and focus groups were used for data collection. Data was then analyzed using qualitative content analysis. Health communication is an integral part of health promotion practice in PHC in this case study. However, there was a lack of consensus among health professionals on what a health promotion approach was, causing discrepancy in approaches and practices of health communication. Two themes emerged from the data analysis: Communicating health and environment for health communication. The themes represented individual and organizational factors that affected health communication practice in PHC and thus need to be taken into consideration in the development of the planned health channel. Health communication practiced in PHC is individual based, preventive and reactive in nature, as opposed to population based, promotive and proactive in line with a health promotion approach. The most significant challenge in developing an ICT supported health communication channel for health promotion identified in this study, is profiling a health promotion approach in PHC.

    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)

  15. Do advertisements for antihypertensive drugs in Australia promote quality prescribing? A cross-sectional study

    Full Text Available Abstract Background 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. Methods 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. Results 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

    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

  1. 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

    In this article, organizational structures in hospitals are discussed as possible capacities for hospital health promotion (HP) implementation, based on data from the PRICES-HPH study. PRICES-HPH is a cross-sectional evaluation study of the International Network of Health Promoting Hospitals & Health Services (HPH-Network) and was conducted in 2008-2012. Data from 159 acute care hospitals were used in the analysis. Twelve organizational structures, which were denoted as possible organizational health promotion capacities in previous literature, were tested for their association with certain strategic HP implementation approaches. Four organizational structures were significantly (p = 0.05) associated with one or more elaborate and comprehensive strategic HP implementation approaches: (1) a health promotion specific quality assessment routine; (2) an official hospital health promotion team; (3) a fulltime hospital health promotion coordinator; and (4) officially documented health promotion policies, strategies or standards. The results add further evidence to the importance of organizational capacity structures for hospital health promotion and identify four tangible structures as likely candidates for organizational HP capacities in hospitals. © The Author (2013).

    Glyoxal is formed endogenously and at a higher rate in the case of hyperglycemia. Glyoxal is also a food processing contaminant and has been shown to be mutagenic and genotoxic in vitro. The tumourigenic potential of glyoxal was investigated using the multiple intestinal neoplasia (Min) mouse model, which spontaneously develops intestinal tumours and is susceptible to intestinal carcinogens. C57BL/6J females were mated with Min males. Four days after mating and throughout gestation and lactation, the pregnant dams were exposed to glyoxal through drinking water (0.0125%, 0.025%, 0.05%, 0.1%) or regular tap water. Female and male offspring were housed separately from PND21 and continued with the same treatment. One group were only exposed to 0.1% glyoxal from postnatal day (PND) 21. There was no difference in the number of intestinal tumours between control and treatment groups. However, exposure to 0.1% glyoxal starting in utero and at PND21 caused a significant increase in tumour size in the small intestine for male and female mice in comparison with respective control groups. This study suggests that glyoxal has tumour growth promoting properties in the small intestine in Min mice. Copyright © 2016 Norwegian Institute of Public Health. Published by Elsevier Ltd..

    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.

    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...... (intracellular and extracellular) forms. We observed that 1) the growth-promoting effect of S100A4 is due to its activation of NFκB, 2) S100A4-deficient tumors exhibit reduced NFκB activity, 3) S100A4 regulates NFκB through the RAGE receptor, and 4) S100A4 and RAGE co-localize in prostatic tissues of mice......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...

    Gene transcription is strictly controlled by the interplay of regulatory events at gene promoters and gene-distal regulatory elements called enhancers. Despite extensive studies of enhancers, we still have a very limited understanding of their mechanisms of action and their restricted spatio......-temporal activities. A better understanding would ultimately lead to fundamental insights into the control of gene transcription and the action of regulatory genetic variants involved in disease. Here, I review and discuss pros and cons of state-of-the-art genomics methods to localize and infer the activity...... of enhancers. Among the different approaches, profiling of enhancer RNAs yields the highest specificity and may be superior in detecting in vivo activity. I discuss their apparent similarities to promoters, which challenge the established view of enhancers and promoters as distinct entities, and present...

    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. 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. Results 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. Conclusions 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.

    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

    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.

    Full Text Available Introduction: Health beliefs significantly affect health promoting self-care behaviors. The most important model designed based on health beliefs is the Health Belief Model. This study examined the association between health belief model constructs and demographic factors with behaviors in elderly. Materials and Methods: This descriptive-analytical study was performed on 465 elders referring to Tehran's cultural centers recruited with a multi-stage sampling method. Study instruments were questionnaires regarding demographic information, health beliefs, self-efficacy and health-promoting self-care behaviors. Data analysis was performed using SPSS-22 software by Independent T-test, one-way ANOVA, Pearson correlation and Multiple linear regression. Results: The mean (±SD age of subjects was 68.24±6.12 years and the mean of general self-care score was 1.79±0.36. Gender (P=0.011, economy (P<0.001, education level (P<0.001 and age (P=0.008 were significantly associated with self-care behaviors. Regression analysis showed that perceived barriers, self-efficacy and perceived severity were determinants of behavior (P<0.001. Conclusion: According to the results of this study, it is essential to pay special attention to self-efficacy, perceived severity and perceived barriers to design health education for elderly.

    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.)

    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 .

    This study aimed to assess public attitudes in Japan to the promotion of genomic selection in crop studies and to examine associated factors. We analysed data from a nationwide opinion survey. A total of 4,000 people were selected from the Japanese general population by a stratified two-phase sampling method, and 2,171 people participated by post; this survey asked about the pros and cons of crop-related genomic studies promotion, examined people's scientific literacy in genomics, and investigated factors thought to be related to genomic literacy and attitude. The relationships were examined using logistic regression models stratified by gender. Survey results showed that 50.0% of respondents approved of the promotion of crop-related genomic studies, while 6.7% disapproved. No correlation was found between literacy and attitude towards promotion. Trust in experts, belief in science, an interest in genomic studies and willingness to purchase new products correlated with a positive attitude towards crop-related genomic studies.

    To identify predictors of initial weight loss among women with abdominal obesity by using a path model. Successful weight loss in the initial stages of long-term weight management may promote weight loss maintenance. A longitudinal study design. Study participants were 75 women with abdominal obesity, who were enrolled in a 12-month Community-based Heart and Weight Management Trial and followed until a 6-month assessment. The Weight Efficacy Lifestyle, Exercise Self-Efficacy and Health Promoting Lifestyle Profile-II measured diet self-efficacy, exercise self-efficacy and health-promoting behaviour respectively. All endogenous and exogenous variables used in our path model were change variables from baseline to 6 months. Data were collected between May 2011-May 2012. Based on the path model, increases in both diet and exercise self-efficacy had significant effects on increases in health-promoting behaviour. Increases in diet self-efficacy had a significant indirect effect on initial weight loss via increases in health-promoting behaviour. Increases in health-promoting behaviour had a significant effect on initial weight loss. Among women with abdominal obesity, increased diet self-efficacy and health-promoting behaviour were predictors of initial weight loss. A mechanism by which increased diet self-efficacy predicts initial weight loss may be partially attributable to health-promoting behavioural change. However, more work is still needed to verify causality. Based on the current findings, intensive nursing strategies for increasing self-efficacy for weight control and health-promoting behaviour may be essential components for better weight loss in the initial stage of a weight management intervention. © 2015 John Wiley & Sons Ltd.

    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

    Full Text Available Abstract Background Binding of a bacteria to a eukaryotic cell triggers a complex network of interactions in and between both cells. P. aeruginosa is a pathogen that causes acute and chronic lung infections by interacting with the pulmonary epithelial cells. We use this example for examining the ways of triggering the response of the eukaryotic cell(s, leading us to a better understanding of the details of the inflammatory process in general. Results Considering a set of genes co-expressed during the antibacterial response of human lung epithelial cells, we constructed a promoter model for the search of additional target genes potentially involved in the same cell response. The model construction is based on the consideration of pair-wise combinations of transcription factor binding sites (TFBS. It has been shown that the antibacterial response of human epithelial cells is triggered by at least two distinct pathways. We therefore supposed that there are two subsets of promoters activated by each of them. Optimally, they should be "complementary" in the sense of appearing in complementary subsets of the (+-training set. We developed the concept of complementary pairs, i.e., two mutually exclusive pairs of TFBS, each of which should be found in one of the two complementary subsets. Conclusions We suggest a simple, but exhaustive method for searching for TFBS pairs which characterize the whole (+-training set, as well as for complementary pairs. Applying this method, we came up with a promoter model of antibacterial response genes that consists of one TFBS pair which should be found in the whole training set and four complementary pairs. We applied this model to screening of 13,000 upstream regions of human genes and identified 430 new target genes which are potentially involved in antibacterial defense mechanisms.

    A human security framework posits that individuals are the focus of strategies that protect the safety and integrity of people by proactively promoting children's well being, placing particular emphasis on prevention efforts and health promotion. This article applies this framework to a rights-based approach in order to examine the health and human rights of children affected by HIV/AIDS. The SAFE model describes sources of insecurity faced by children across four fundamental dimensions of child well-being and the survival strategies that children and families may employ in response. The SAFE model includes: Safety/protection; Access to health care and basic physiological needs; Family/connection to others; and Education/livelihoods. We argue that it is critical to examine the situation of children through an integrated lens that effectively looks at human security and children's rights through a holistic approach to treatment and care rather than artificially limiting our scope of work to survival-oriented interventions for children affected by HIV/AIDS. Interventions targeted narrowly at children, in isolation of their social and communal environment as outlined in the SAFE model, may in fact undermine protective resources in operation in families and communities and present additional threats to children's basic security. An integrated approach to the basic security and care of children has implications for the prospects of millions of children directly infected or indirectly affected by HIV/AIDS around the world. The survival strategies that young people and their families engage in must be recognized as a roadmap for improving their protection and promoting healthy development. Although applied to children affected by HIV/AIDS in the present analysis, the SAFE model has implications for guiding the care and protection of children and families facing adversity due to an array of circumstances from armed conflict and displacement to situations of extreme poverty.

    Social network interventions that utilize informal systems of helping can be an important strategy for health promotion change. This article describes the development, implementation and evaluation of a natural (lay) helping intervention for health promotion change, specifically designed for women in small rural blue-collar worksites. One hundred and four women in four intervention worksites were recruited as natural helpers, and received health and skill-building education over an 18-month period. Qualitative evaluation showed: (1) two patterns of natural helping for women, i.e. participation due to a specific health concern with either themselves or others in their personal networks, and participation due to a larger sense of the importance of health and prevention; (2) over time natural helpers expanded the diffusion of health promotion information from close network members to co-workers and were more likely to be approached by their co-workers for information; (3) group activities at the worksite, particularly around physical activity, increased over time; and (4) because of time constraints at the workplace, written materials were a major way of spreading information to co-workers. This study shows that women can be recruited and trained to diffuse health promotion information and provide support to co-workers for health behavior change.

    Theoretical models have been developed, and are currently being refined, to explain the edge plasma-antenna interaction that occurs during ICRF heating. The periodic structure of a Faraday shielded antenna is found to result in strong ponderomotive force in the vicinity of the antenna. A fluid model, which incorporates the ponderomotive force, shows an increase in transport to the Faraday shield. A kinetic model shows that the strong antenna near fields act to increase the energy of deuterons which strike the shield, thereby increasing the sputtering of shield material. Estimates of edge impurity harmonic heating show no significant heating for either in or out-of-phase antenna operation. Additionally, a particle model for electrons near the shield shows that heating results from the parallel electric field associated with the fast wave. A quasilinear model for edge electron heating is presented and compared to the particle calculations. The models' predictions are shown to be consistent with measurements of enhanced transport.

    Oil demand is expected to substantially grow in the future, and the use of oil with combustibles such as hull, baggase and waste is considered from an effective use of energy. A regional model survey was conducted as measures to reduce environmental loads where the fuel mixing combustion with coal and other energy is made the core. The domestic production amount of hull is 2.4-3.0 tons/year, which have a heating value of 3,500 kcal/kg. If hull can be formed into the one storable for a the long term (the one mixed with low grade coal, etc.), it can be a fuel for stable supply. Bagasse is produced 100 million tons/year, which have a heating value of 2,500 kcal/kg. Among wastes, waste tire, plastics, waste, sludge, etc. have a lot of problems in terms of price and environment, but each of them has a heating value during 3,000-10,000 kcal/kg. As to the coal combustion, the pollutional regulation on it is strict, and much higher processing technology is needed. The technology of coal fuel mixing combustion with other energy has not risen higher than the developmental level. Though the technology is a little bit higher in price than the coal fuel single combustion, it is viable. 38 refs., 32 figs., 65 tabs.

    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.

    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

    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.

    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.

  1. The promotion of oral health within the Healthy School context in England: a qualitative research study

    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.

    To examine the literature from the past 20 years and identify those studies that support the economic merit of health promotion. A panel of experts was used to identify the top studies supporting the purpose of this article. Studies were chosen based on the following criteria: the study (1) examined the relationship between health risks and financial outcomes, or health promotion programs and financial outcomes; (2) provided strong and compelling financial data supporting the worth of health promotion; (3) had a high-quality methodology; (4) answered an important question or replicated important findings with superior methodology; and (5) represented U.S.-based initiatives published since 1980. After initially nominating a group of studies for consideration, panelists rated each on a scale from 1 to 3 representing their opinion of importance. Studies rating the highest were included for this discussion. Studies were analyzed by population characteristics, design, statistical tests, limitations, and results. This information was summarized for each identified article. A relationship between modifiable health risk factors and health care costs is supported by research. Health promotion interventions appear to provide positive financial returns, most notably for health care costs and absenteeism reduction. Private sector initiatives seem to be driving economic-based research. Overall, health promotion shows promising results for providing financial advantages for its sponsors; however, if this discipline is to show its true worth, considerable funding is needed from government or philanthropic sources to cover the substantial costs of quality research.

    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.

    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.

    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.

    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.' This study provides a hitherto

    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

    Background 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. Methodology/Principal Findings 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. Conclusions/Significance This is the first

    Promoting Excellence in End-of Life Care, a national program of The Robert Wood Johnson Foundation, funded 22 demonstration projects representing a wide range of health care settings and patient populations to develop innovative models for delivering palliative care that addressed documented deficiencies in the care of patients and families facing the final stage of life. To determine the practicality (feasibility of development and operation as well as acceptance by stakeholders) of new models of care and to determine the impact of the models on access to, quality of and financing for palliative care. The program cannot report scientifically rigorous outcomes, but the grant-funded projects used a variety of methods and measures to assess acceptance of new models and their impact from the perspectives of various stakeholders, including patients and their families, clinicians, administrators and payers. While it is not possible to aggregate data across projects, the data reported to the Promoting Excellence national program office were used to describe program impact with respect to the practicality of palliative care service integration into existing clinical care settings (feasibility and acceptance by stakeholders), the availability and use of palliative care services (access), quality of care (conformance to patient expectations and accepted clinical standards) and costs of care. The 22 projects provided services in urban as well as rural settings, in integrated health systems, hospitals, outpatient clinics, cancer centers, nursing homes, renal dialysis clinics, inner city public health and safety net systems and prisons. Populations served included prison inmates, military veterans, renal dialysis patients, Native Americans, Native Alaskans, and African American patients, inner-city medically underserved patients, pediatric patients, and persons with serious mental illness patients.

    Full Text Available In today’s competitive business world customers are considered to be kings. Customers have several choices to make among alternative products, and they exercise a high level of influence in the market with respect to product size, quality and price. Hence, it is important for producers to meet the needs of customers in order to stay competitive. One of the marketing communication tools that is used in attracting the attention of the customer and build their loyalty is sales promotion. The aim of this paper therefore is to determine the effect of sales promotion on customer loyalty in the telecommunication industry. In this study, the survey method was used in gathering information from the respondents. Simple random sampling was used to select a sample size of 310, while descriptive and inferential statistical analyses were conducted with the aid of SPSS software. Producers spend a large part of their total marketing communication expenses on sales promotion. Hence, this paper attempts to find the effect of sales promotion on customer loyalty using a sample of customers of mobile telecommunication services. The paper found that, there is positive relationship between sales promotion and customer loyalty. More importantly, it was discovered that non-loyal customers are more prone to switch to competing products as a result of sales promotion than loyal customers.

    Despite the importance of breakfast, especially for students, unfortunately, this meal is usually ignored in daily routine. The aim of this study was to identify determinants among female high school students of Yazd province based on the Pender Health Promotion Model. This was a cross-sectional study conducted to examine 200 female high school students of Yazd, selected by cluster sampling method in 2016. A researcher-made questionnaire, based on Pender's Health Promotion Model, was used as a data collection tool. A panel of experts and Cronbach's alpha coefficient were used to confirm the questionnaire validity and reliability. In order to analyze descriptive data, SPSS version 22 was used. AMOS software (v.23) was employed for path analysis. Direct impact of activity -related affect (0.300), interpersonal influences (0.276), and perceived barriers to eating breakfast (-0.223) were approved at significance level p<0.000. By influencing perceived barriers, perceived self-efficacy and previous related behavior indirectly affected breakfast consumption. These components determined 33% of breakfast consumption. By planning to create a positive feeling in students to have breakfast, to involve family and friends to encourage students to eat breakfast, to reduce barriers to have breakfast by increasing students' self-efficacy, the behavior of having breakfast among students can be improved.

  15. 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.

  16. Using Computer Simulations for Promoting Model-based Reasoning. Epistemological and Educational Dimensions

    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.

    This article describes an example of molecular replacement in which atomic models are used to interpret electron-density maps determined using single-particle electron-microscopy data. 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

    1995-08-01

    Six middle distillates (MDs) were tested for tumor initiating/promoting activity after application to the skin of 30 male CD-1 (ICR) BR mice per group. As the control, 7,12-dimethylbenz[a]-anthracene (DMBA) was used for initiation followed by 12-O-tetradecanoylphorbol-13-acetate (TPA) for promotion. For assessing the tumor-initiating activity, 50 microliters of neat MDs was administered for 5 days with subsequent TPA promotion. In the promotion bioassay, after DMBA initiation 50 microliters of the neat MDs was administered twice weekly until Week 28. For the examination of complete carcinogenic activity, one MD was given without DMBA initiation. Hyperkeratosis, hyperplasia, and dermal inflammation, occurring during the initiation with the MDs, were completely reversible during the 2-week treatment-free period after initiation. Similar skin findings were observed during promotion with the MDs. Regarding the number of affected animals and the severity of the response, TPA was more irritating than the MDs. The initiation study revealed skin tumors for the DMBA/TPA control (30/30), MD 57,389 (14/30), MD 57,396 (5/30), MD 57,383 (4/30) and MD 57,324 (2/30). The promotion study revealed tumor induction by MDs 57,389 (9/30), 57,324 (1/30), 57,393 (1/30), and 57,396 (1/30). Two of 30 animals treated with MD 57,389 developed tumors without DMBA initiation thus indicating that it also is a complete carcinogen. MD 57,399 caused neither initiating nor promoting effects. The tumors observed were diagnosed histopathologically predominantly as squamous cell papillomas.(ABSTRACT TRUNCATED AT 250 WORDS)

    Full Text Available Cognitive dysfunction following stroke significantly impacts quality of life and functional independance; yet, despite the prevalence and negative impact of cognitive deficits, post-stroke interventions almost exclusively target motor impairments. As a result, current treatment options are limited in their ability to promote post-stroke cognitive recovery. Cyclosporin A (CsA has been previously shown to improve post-stroke functional recovery of sensorimotor deficits. Interestingly, CsA is a commonly used immunosuppressant and also acts directly on endogenous neural precursor cells (NPCs in the neurogenic regions of the brain (the periventricular region and the dentate gyrus. The immunosuppressive and NPC activation effects are mediated by calcineurin-dependent and calcineurin-independent pathways, respectively. To develop a cognitive stroke model, focal bilateral lesions were induced in the medial prefrontal cortex (mPFC of adult mice using endothelin-1. First, we characterized this stroke model in the acute and chronic phase, using problem-solving and memory-based cognitive tests. mPFC stroke resulted in early and persistent deficits in short-term memory, problem-solving and behavioral flexibility, without affecting anxiety. Second, we investigated the effects of acute and chronic CsA treatment on NPC activation, neuroprotection, and tissue damage. Acute CsA administration post-stroke increased the size of the NPC pool. There was no effect on neurodegeneration or lesion volume. Lastly, we looked at the effects of chronic CsA treatment on cognitive recovery. Long-term CsA administration promoted NPC migration toward the lesion site and rescued cognitive deficits to control levels. This study demonstrates that CsA treatment activates the NPC population, promotes migration of NPCs to the site of injury, and leads to improved cognitive recovery following long-term treatment.

    The Antibiotics Smart Use (ASU) programme was introduced in Thailand as a model to promote the rational use of medicines, starting with antibiotics. The programme's first phase consisted of assessing interventions intended to change prescribing practices; the second phase examined the feasibility of programme scale-up. Currently the programme is in its third phase, which centres on sustainability. This paper describes the concept behind ASU, the programme's functional modalities, the development of its conceptual framework and the implementation of its first and second phases. To change antibiotic prescription practices, multifaceted interventions at the individual and organizational levels were implemented; to maintain behaviour change and scale up the programme, interventions at the network and policy levels were used. The National Health Security Office has adopted ASU as a pay-for-performance criterion, a major achievement that has led to the programme's expansion nationwide. Despite limited resources, programme scale-up and sustainability have been facilitated by the promotion of local ownership and mutual recognition, which have generated pride and commitment. ASU is clearly a workable entry point for efforts to rationalize the use of medicines in Thailand. Its long-term sustainability will require continued local commitment and political support, effective auditing and integration of ASU into routine systems with appropriate financial incentives.

    The information-processing model of the attitude and behavior change process was critically examined and extended from six to 12 levels for a better analysis of change due to mass media campaigns. Findings from social psychology and communications research, and from evaluations of mass media health promotion programs, were reviewed to determine how source, message, channel, receiver, and destination variables affect each of the levels of change of major interest (knowledge, beliefs, attitudes, intentions and behavior). Factors found to most likely induce permanent attitude and behavior change (most important in health promotion) were: presentation and repetition over long time periods, via multiple sources, at different times (including "prime" or high-exposure times), by multiple sources, in novel and involving ways, with appeals to multiple motives, development of social support, and provisions of appropriate behavioral skills, alternatives, and reinforcement (preferably in ways that get the active participation of the audience). Suggestions for evaluation of mass media programs that take account of this complexity were advanced.

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

    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.

    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.

    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.

    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.

    OBJECTIVES: This study examined the effects of pricing and promotion strategies on purchases of low-fat snacks from vending machines. METHODS: Low-fat snacks were added to 55 vending machines in a convenience sample of 12 secondary schools and 12 worksites. Four pricing levels (equal price, 10% reduction, 25% reduction, 50% reduction) and 3 promotional conditions (none, low-fat label, low-fat label plus promotional sign) were crossed in a Latin square design. Sales of low-fat vending snacks were measured continuously for the 12-month intervention. RESULTS: Price reductions of 10%, 25%, and 50% on low-fat snacks were associated with significant increases in low-fat snack sales; percentages of low-fat snack sales increased by 9%, 39%, and 93%, respectively. Promotional signage was independently but weakly associated with increases in low-fat snack sales. Average profits per machine were not affected by the vending interventions. CONCLUSIONS: Reducing relative prices on low-fat snacks was effective in promoting lower-fat snack purchases from vending machines in both adult and adolescent populations. PMID:11189801

    Full Text Available The Peace Accords emphasized creating a new police force that would be diametrically opposite to previous security forces. This change would have to be expressed symbolically, and from the onset it would have to underscore the fact that the main weapon of the police would be intelligence. From its foundation to June 2011, a total of 30,344 people have graduated from the Academy. Currently, in the process of training new police with greater quality, and modernizing the entire police force, it faces the difficult challenge of adopting the Community Police philosophy to empower this model for action, promoting a new relationship between community and law enforcement, and between managers and operational personnel in the agency. Nevertheless,police training is not enough if there are no significantchanges in the organizational climate and culture within the law enforcement agency.DOI: http://dx.doi.org/10.5377/rpsp.v1i1.1390

    The inability to imitate is a salient diagnostic marker for autism. It has been suggested that for children with autism, imitation may be a prerequisite skill that can assist in the development of various skills. Using a multiple baseline design across subjects, the purpose of this research was to determine if two interventions, reciprocal imitation training and video modeling were effective in promoting imitation acquisition in young children with autism. Six boys were matched across various features (i.e., age, language, autism severity) and randomly placed in a treatment condition. Results indicated that all six participants increased their imitation skills to varying degrees in both conditions, and imitation maintained and generalized at higher than baseline levels post treatment.

    Effective health promotion is of great importance from clinical as well as from public health perspectives and therefore should be encouraged. Especially regarding health promotion in the elderly, general practitioners (GPs) have a key role. Nevertheless, evidence suggests a lack of health promotion by GPs, especially in this age group. The aim of our study was to assess self-perceived attitudes, barriers and facilitators of GPs to provide health promotion in the elderly. We performed a qualitative focus group study with 37 general practitioners. The focus group interviews were recorded digitally, transcribed literally and analysed with ATLAS.ti, a software program for qualitative text analysis. Among the participating GPs, definitions of health promotion varied widely and the opinions regarding its effectiveness were very heterogeneous. The two most important self-perceived barriers for GPs to provide health promotion in the elderly were lack of time and insufficient reimbursement for preventive and health promotion advice. As intervention to increase health promotion in the elderly, GPs suggested, for example, integration of health promotion into under and postgraduate training. Changes at the practice level such as involving the practice nurse in health promotion and counselling were discussed very controversially. Health promotion, especially in the elderly, is crucial but in the opinion of the GPs we involved in our study, there is a gap between public health requirements and the reimbursement system. Integration of health promotion in medical education may be needed to increase knowledge as well as attitudes of GPs regarding this issue.

    The transient nature of construction work makes it difficult to conduct longitudinal worksite-based health promotion activities. As part of a workplace health assessment pilot study, we worked with a commercial lunch truck company to disseminate four types of health education materials including cancer screening, workplace injury prevention, fruit and vegetable consumption, and smoking cessation to construction workers purchasing food items from the truck during their job breaks. Two weeks following the worksite assessment, we followed up with these workers to ascertain their use of the health promotion materials. Of the 54 workers surveyed, 83% reported reviewing and sharing the cancer screening materials with their families, whereas 44% discussed the cancer screening materials with coworkers. Similar proportions of workers reviewed, shared, and discussed the other health promotion materials with their family. Lunch trucks may be an effective strategy and delivery method for educating construction workers on healthy behaviors and injury prevention practices.

    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.

    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. 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. 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. The NCSP should consider developing a range of more discrete but eye

    Ethnobotanical surveys were conducted to locate culturally important, regionally scarce, and disappearing medicinal plants via a novel participatory methodology which involves healer-expert knowledge in interactive spatial modeling to prioritize conservation efforts and thus facilitate health promotion via medicinal plant resource sustained availability. These surveys, conducted in the Maya Mountains, Belize, generate ethnobotanical, ecological, and geospatial data on species which are used by Q'eqchi' Maya healers in practice. Several of these mountainous species are regionally scarce and the healers are expressing difficulties in finding them for use in promotion of community health and wellness. Based on healers' input, zones of highest probability for locating regionally scarce, disappearing, and culturally important plants in their ecosystem niches can be facilitated by interactive modeling. In the present study, this is begun by choosing three representative species to train an interactive predictive model. Model accuracy was then assessed statistically by testing for independence between predicted occurrence and actual occurrence of medicinal plants. A high level of accuracy was achieved using a small set of exemplar data. This work demonstrates the potential of combining ethnobotany and botanical spatial information with indigenous ecosystems concepts and Q'eqchi' Maya healing knowledge via predictive modeling. Through this approach, we may identify regions where species are located and accordingly promote for prioritization and application of in situ and ex situ conservation strategies to protect them. This represents a significant step toward facilitating sustained culturally relative health promotion as well as overall enhanced ecological integrity to the region and the earth.

    Lactoferrin, an iron-binding glycoprotein which belongs to the transferrin family, has been shown to promote bone growth. However, reports regarding effects of lactoferrin on bone regeneration during distraction osteogenesis are limited. Our study was designed to investigate the effect of bovine lactoferrin treatment on bone formation of the distracted callus. We asked whether bovine lactoferrin enhances bone formation of the distraction callus as determined by (1) radiographic and histologic appearances; (2) dual-energy x-ray absorptiometry (DXA) analysis of bone mineral composition and bone mineral density; (3) micro-CT measures of trabecular architecture; and (4) biomechanical strength of the healing bone. Additionally, serology, reverse transcription (RT)-PCR, and immunohistochemistry were used to explore the possible mechanisms of bovine lactoferrin use on bone formation during distraction osteogenesis. Unilateral tibial osteodistraction was performed on 80 New Zealand White rabbits with a distraction rate of 1 mm per day for 10 days. Animals then were divided randomly into two groups: (1) vehicle and (2) bovine lactoferrin. At 4 and 8 weeks after completion of distraction, the animals were sacrificed. Lengthened tibias and serum samples were obtained and subjected to radiologic, DXA, micro-CT, histologic, and biomechanical examinations, and serum, RT-PCR and immunohistochemical analyses. Radiologic, DXA, micro-CT, histologic, and biomechanical examinations indicated that bovine lactoferrin treatment not only accelerated bone formation at early stages of distraction osteogenesis but also promoted bone consolidation at late stages. The ultimate force of the distracted calluses was increased by 37% (118.8 ± 6.65 N in the lactoferrin group and 86.5 ± 5.47 N in the vehicle group; p bovine lactoferrin treatment significantly increased serum levels of bone alkaline phosphatase and decreased serum levels of tartrate resistant acid phosphatase 5b.

    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.

    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.

    2003-10-01

    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

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

    Despite an increased risk of mental health problems in adolescents with autism spectrum disorder (ASD), there is limited research on effective prevention approaches for this population. Funded by the Cooperative Research Centre for Living with Autism, a theoretically and empirically supported school-based preventative model has been developed to alter the negative trajectory and promote wellbeing and positive mental health in adolescents with ASD. This conceptual paper provides the rationale, theoretical, empirical and methodological framework of a multilayered intervention targeting the school, parents and adolescents on the spectrum. Two important interrelated protective factors have been identified in community adolescent samples, namely the sense of belonging (connectedness) to school and the capacity for self and affect regulation in the face of stress (i.e. resilience). We describe how a confluence of theories from social psychology, developmental psychology and family systems theory, along with empirical evidence (including emerging neurobiological evidence), supports the interrelationships between these protective factors and many indices of wellbeing. However, the characteristics of ASD (including social and communication difficulties, and frequently difficulties with changes and transitions, and diminished optimism and self-esteem) impair access to these vital protective factors. The paper describes how evidence-based interventions at the school level for promoting inclusive schools (using the Index for Inclusion) and interventions for adolescents and parents to promote resilience and belonging [using the Resourceful Adolescent Program (RAP)] are adapted and integrated for adolescents with ASD. This multisite proof-of-concept study will confirm whether this multilevel school-based intervention is promising, feasible and sustainable.

    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

    Huntington disease (HD) is caused by the expression of mutant huntingtin (mHTT) bearing a polyglutamine expansion. In HD, mHTT accumulation is accompanied by a dysfunction in basal autophagy, which manifests as specific defects in cargo loading during selective autophagy. Here we show that the expression of mHTT resistant to proteolysis at the caspase cleavage site D586 (C6R mHTT) increases autophagy, which may be due to its increased binding to the autophagy adapter p62. This is accompanied by faster degradation of C6R mHTT in vitro and a lack of mHTT accumulation the C6R mouse model with age. These findings may explain the previously observed neuroprotective properties of C6R mHTT. As the C6R mutation cannot be easily translated into a therapeutic approach, we show that a scheduled feeding paradigm is sufficient to lower mHTT levels in YAC128 mice expressing cleavable mHTT. This is consistent with a previous model, where the presence of cleavable mHTT impairs basal autophagy, while fasting-induced autophagy remains functional. In HD, mHTT clearance and autophagy may become increasingly impaired as a function of age and disease stage, because of gradually increased activity of mHTT-processing enzymes. Our findings imply that mHTT clearance could be enhanced by a regulated dietary schedule that promotes autophagy.

    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.

    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.

    Full Text Available Bone homeostasis is tightly regulated to balance bone formation and bone resorption. Many anabolic drugs are used as bone-targeted therapeutic agents for the promotion of osteoblast-mediated bone formation or inhibition of osteoclast-mediated bone resorption. Previous studies showed that ginsenoside Re has the effect of the suppression of osteoclast differentiation in mouse bone-marrow derived macrophages and zebrafish. Herein, we investigated whether ginsenoside Re affects osteoblast differentiation and mineralization in in vitro and in vivo models. Mouse osteoblast precursor MC3T3-E1 cells were used to investigate cell viability, alkaline phosphatase (ALP activity, and mineralization. In addition, we examined osteoblastic signaling pathways. Ginsenoside Re affected ALP activity without cytotoxicity, and we also observed the stimulation of osteoblast differentiation through the activation of osteoblast markers including runt-related transcription factor 2, type 1 collagen, ALP, and osteocalcin in MC3T3-E1 cells. Moreover, Alizarin red S staining indicated that ginsenoside Re increased osteoblast mineralization in MC3T3-E1 cells and zebrafish scales compared to controls. These results suggest that ginsenoside Re promotes osteoblast differentiation as well as inhibits osteoclast differentiation, and it could be a potential therapeutic agent for bone diseases.

    The study aimed to compare the experiences with the organization of universal public healthcare systems in relation to health promotion in primary care units in Florianópolis, Santa Catarina State, Brazil, and Toronto, Ontario, Canada. This was a descriptive exploratory study with a qualitative approach in primary care units. Data were collected with semi-structured interviews containing questions on health promotion practices, with 25 health professionals in Florianópolis and 10 in Toronto. The data were discussed using thematic analysis, identifying the practices, difficulties, and facilities in health promotion. In the two cities, 60% of health professionals and health administrators had not received any specific knowledge on health promotion during their training. As for health promotion skills, health professionals in Toronto identified them with autonomy and social determinants, while in Florianópolis they were related to health education and community participation. In both cities, health promotion practices are targeted to individual and collective activities. The motivation to act comes from interdisciplinarity and the demands raised by the population. Health promotion is a relevant form of care and stimulus for individual and community autonomy, in light of social determinants. Such practices aim at comprehensive health for the community, but there are limits in the teams that still conduct disease-centered activities. Resources are limited, requiring inter-sector actions to improve quality of life. Healthcare centers on the hegemonic model, and progress is needed to achieve a positive approach to health and social determinants.

    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.

  9. Computer-assisted molecular modeling of tumor promoters: rationale for the activity of phorbol esters, teleocidin B, and aplysiatoxin

    In the two-stage model of skin carcinogenesis, it is believed that initiators bind to DNA and that tumor promoters such as phorbol 12-tetradecanoate 13-acetate (TPA) bind noncovalently to membrane-associated high-affinity receptors, probably protein kinase C. Two other types of potent tumor-promoting substances, aplysiatoxin and teleocidin, appear to act also by binding to and activating protein kinase C, even though their chemical structures are quite different. Therefore, the authors have undertaken computer modeling of the special relationship of various functional groups in these three chemical classes of tumor promoters in an attempt to explain how these diverse structures bind to the same receptor molecule. They propose a stereochemical model in which the oxygens in TPA at C-3, C-4, C-9, and C-20 (O-3, O-4, O-9, and O-20) correspond to the O-11, N-13, N-1, and O-24 positions in teleocidin and the O-27, O-3, O-11, and O-30 oxygens in aplysiatoxin, respectively. In this model all distances with respect to overlap of the corresponding atoms are <1 A. In addition, all three types of molecules have their hydrophobic moieties oriented in the similar position. This model is further discussed with respect to other compounds showing various degrees of activity as tumor promoters, including mezerein, ingenol, and 4α-TPA. The model explains how chemically diverse structures can have similar biological activity as tumor promoters and provides a basis for designing both agonists and antagonists of tumor promoters

    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

    Research in the past decade has revealed average to poor menstrual health among many Iranian girls. The present study investigated the effectiveness of a health promotion project on improving menstrual health in adolescent girls in Iran. A quasi-experimental study was conducted to evaluate the effectiveness of the health intervention program. A total of 698 students (study participants and controls) in several schools in Mazandaran province, Iran were included. The project comprised 10 two-hour educational sessions. Educational topics included the significance of adolescence, physical and emotional changes during adolescence, pubertal and menstruation health and premenstrual syndrome. A self-administered questionnaire measuring demographic characteristics, behaviors during menstruation, menstrual patterns, sources of information about menstruation and personal health data was administered. The questionnaire was administered to all participating students after the experimental group received the training. Among the most significant results was the impact of educational sessions on bathing and genital hygiene. A total of 61.6% in the experimental group compared with 49.3% in the control group engaged in usual bathing during menstruation (p = 0.002). Individual health status was significantly statistically correlated with menstrual health. Attitude towards menstruation was also significantly related to menstrual health. The present study confirms that educational interventions, such as the health promotion project in this study, can be quite effective in promoting menstrual health.

    Full Text Available Background: Recent studies show adolescent health-related behaviours to co-occur synergistically. This paper describes the study design for an exploratory trial on the effects of a comprehensive, whole-school health promoting school intervention. This intervention tackles seven different behavioural domains simultaneously via a combination of education, creating a healthy environment and introducing healthy behavioural policies. Additionally, extensive partnerships are formed between schools, parents, neighbourhoods and youth health authorities to coordinate health promotion efforts.Study design and data collection methods: The intervention will be implemented at two secondary schools. Results will be compared with two control schools (n≈1500. The intervention's effectiveness in changing student behaviours as well as physical and psychosocial health status along with qualitative lessons learned on the integration of youth health care services and school health education practices are the main aimed outcomes of this study. Data are collected via a mixed methods design combining an annual youth health (behaviour monitor with a qualitative process evaluation via interviews with key stakeholders.Data analysis: A multilevel analysis is performed combined with a systematic analysis of qualitative interview data.Conclusions: This study will produce an evaluation of a comprehensive health promoting school intervention that combines an integrated approach of schools, neighbourhoods, families and youth health services to improve adolescent health.

    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.

    2009-01-01

    Many believe that fast food promotion is a significant cause of the obesity epidemic in North America. Industry members argue that promotion only reallocates brand shares and does not increase overall demand. We study the effect of fast food promotion on market share and total demand by estimating a discrete / continuous model of fast food restaurant choice and food expenditure that explicitly accounts for both spatial and temporal determinants of demand. Estimates are obtained using a unique...

    The aim of this research was to find out whether 7E learning cycle under hypnoteaching model can enhance students’ mathematical problem-solving skill. This research was quasi-experimental study. The design of this study was pretest-posttest control group design. There were two groups of sample used in the study. The experimental group was given 7E learning cycle under hypnoteaching model, while the control group was given conventional model. The population of this study was the student of mathematics education program at one university in Tangerang. The statistical analysis used to test the hypothesis of this study were t-test and Mann-Whitney U. The result of this study show that: (1) The students’ achievement of mathematical problem solving skill who obtained 7E learning cycle under hypnoteaching model are higher than the students who obtained conventional model; (2) There are differences in the students’ enhancement of mathematical problem-solving skill based on students’ prior mathematical knowledge (PMK) category (high, middle, and low).

    Introduction Sports clubs form a potential setting for health promotion, but the research is limited. The aim of the Health Promoting Sports Club (HPSC) study was to elucidate the current health promotion activities of youth sports clubs and coaches, and to investigate the health behaviours and health status of youth participating in sports clubs compared to non-participants. Methods and analysis The study design employs cross-sectional multilevel and multimethod research with aspirations to a prospective cohort study in the next phase. The setting-based variables at sports clubs and coaching levels, and health behaviour variables at the individual level, are investigated using surveys; and total levels of physical activity are assessed using objective accelerometer measurements. Health status variables will be measured by preparticipation screening. The health promotion activity of sports clubs (n=154) is evaluated by club officials (n=313) and coaches (n=281). Coaches and young athletes aged 14–16 (n=759) years evaluate the coaches’ health promotion activity. The survey of the adolescents’ health behaviours consist of two data sets—the first is on their health behaviours and the second is on musculoskeletal complaints and injuries. Data are collected via sports clubs (759 participants) and schools 1650 (665 participants and 983 non-participants). 591 (418 athletes and 173 non-athletes) youth, have already participated in preparticipation screening. Screening consists of detailed personal medical history, electrocardiography, flow-volume spirometry, basic laboratory analyses and health status screening, including posture, muscle balance, and static and dynamic postural control tests, conducted by sports and exercise medicine specialists. Ethics and dissemination The HPSC study is carried out conforming with the declaration of Helsinki. Ethical approval was received from the Ethics Committee of Health Care District of Central Finland.

    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.

    Full Text Available Assistance to suicidal patients is problematic both at the hospital and community care level. Inadequacy of facilities, pressured personnel, long waiting time, and professional and social stigmatization are just some of the many issues that interfere with successful treatment. The goal of this paper is to present the functioning of the Life Promotion Clinic (LPC, Australia, and describe its users. The LPC is the first specialized outpatient service in Australia dedicated to the treatment of individuals with suicidal thoughts and behaviors. A description of the service and characteristics of its clients (demographic, psychopathology, risk of suicide are herein presented. Data were collected for 63 male and 175 female patients who attended the LPC over a three-year period. Patients were mostly single females, aged up to 44 years, poorly educated, unemployed or on a pension/benefit. The majority of patients reported at least one suicide attempt, severe depression and anxiety scores, moderate-severe feelings of hopelessness, and high impulsiveness scores. Compared to females, male patients presented with more active desire to kill themselves and higher level of suicidal ideation. We can conclude that establishing a specialist service for treatment of individuals at increased risk for suicide requires consideration of both patient and clinicians needs. The LPC presents an innovative model of community service, capable of engaging patients with serious mental health issues, while making the service accessible to people from various social categories.

    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.

    In industry, especially petrochemical, oil and natural gas industry, required separation process of CO2 gas which is a corrosive gas (acid gas). This characteristic can damage the plant utility and piping systems as well as reducing the caloric value of natural gas. Corrosive characteristic of CO2 will appear in areas where there is a decrease in temperature and pressure, such as at the elbow pipe, tubing, cooler and injector turbine. From disadvantages as described above, then it is important to do separation process in the CO2 gas stream, one of the method for remove CO2 from the gas stream is reactive absorption using alkanolamine based solution with promotor. Therefore, this study is done to determine the kinetics constant of CO2 absorption in diethanolamine (DEA) solution using a glycine promoter. Glycine is chosen as a promoter because glycine is a primary amine compound which is reactive, moreover, glycine has resistance to high temperatures so it will not easy to degradable and suitable for application in industry. The method used in this study is absorption using laboratory scale wetted wall column equipment at atmospheric of pressure. This study will to provide the reaction kinetics data information in order to optimize the separation process of CO2 in the industrialized world. The experimental results show that rising temperatures from 303,15 - 328,15 K and the increase of concentration of glycine from 1% - 3% weight will increase the absorption rate of carbon dioxide in DEA promoted with glycine by 24,2% and 59,764% respectively, also the reaction kinetic constant is 1.419 × 1012 exp (-3634/T) (m3/kmol.s). This result show that the addition of glycine as a promoter can increase absorption rate of carbon dioxide in diethanolamine solution and cover the weaknesses of diethanolamine solution.

    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 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.

    As Sweden changes toward a multicultural society, scientific knowledge of transcultural nursing care becomes increasingly important. Earlier studies in Swedish nursing education have demonstrated a lack of knowledge base in transcultural nursing. Through an extensive review of the literature, a didactic model was developed to help facilitate the establishment of this body of knowledge in transcultural nursing. The article demonstrates how the model applies the content and structure of Leininger's theory of culture care diversity and universality and ethnonursing method in a 3-year nursing program in theory as well as clinical education. The model includes a written guide for faculty members, with references to scientific articles and documents to be used.

    Full Text Available The role of peer-group environment as an influencing factor in purchase decisions is well established. This paper broadens the above premise and studies the influence of peer-group environment on an individual's promotional choice in the context of premium promotions or freebies. Two sets of college students with distinctive peer-group settings in terms of their academic pursuit and residential details have been considered for the study. Discriminant analysis shows that higher interaction and educational orientation of group members influence the customer's promotional preference. Students pursuing professionally oriented courses had a distinctively higher preference for premium-promotions that were hedonic.

    Most low-income Americans fail to meet physical activity recommendations. Inactivity and poor diet contribute to obesity, a risk factor for multiple chronic diseases. Health promotion activities have the potential to improve health outcomes for low-income populations. Measuring the effectiveness of these activities, however, can be challenging in community settings. A "Biking for Health" study tested the impact of a bicycling intervention on overweight or obese low-income Latino and African American adults to reduce barriers to cycling and increase physical activity and fitness. A randomized controlled trial was conducted in Milwaukee, Wisconsin, in summer 2015. A 12-week bicycling intervention was implemented at two sites with low-income, overweight, or obese Latino and African American adults. We found that randomized controlled trial methodology was suboptimal for use in this small pilot study and that it negatively affected participation. More discussion is needed about the effectiveness of using traditional research methods in community settings to assess the effectiveness of health promotion interventions. Modifications or alternative methods may yield better results. The aim of this article is to discuss the effectiveness and feasibility of using traditional research methods to assess health promotion interventions in community-based settings.

    Phramongkutklao College of Medicine is a military medical school and also a health promotion school. As a result, encouraging these medical students to have good attitude toward exercise is considered an important mission for the college. To study the attitudes of medical students at Phramongkutklao College of Medicine about exercise for health promotion. This survey research was carried out in 382 medical students in Academic Year 2008 using questionnaires including personal information, attitude testing and open-ended questions. Statistical analysis was conducted using descriptive analysis: percentage and mean and comparative analysis: t-test and F-test. The overall attitudes of medical students toward exercise were good. The attitudes of the medical cadets were better than those of the civilian medical students. The attitudes and also knowledge about exercise of the higher-year students were generally better than those of the lower-year ones. The attitudes of healthy medical students were higher than those of unhealthy ones. No significant difference in attitude was found between male and female students and between those with different Body Mass Indexes (BMI) and those with different in exercise duration and frequency. The overall medical students' attitudes toward exercise for health promotion in Phramongkutklao College of Medicine were good. The influencial factors were found to be status of medical students, stage of medical study and health status.

    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.

  5. Mathematical study of mixing models

    1999-01-01

    This report presents the construction and the study of a class of models that describe the behavior of compressible and non-reactive Eulerian fluid mixtures. Mixture models can have two different applications. Either they are used to describe physical mixtures, in the case of a true zone of extensive mixing (but then this modelization is incomplete and must be considered only as a point of departure for the elaboration of models of mixtures actually relevant). Either they are used to solve the problem of the numerical mixture. This problem appears during the discretization of an interface which separates fluids having laws of different state: the zone of numerical mixing is the set of meshes which cover the interface. The attention is focused on numerical mixtures, for which the hypothesis of non-miscibility (physics) will bring two equations (the sixth and the eighth of the system). It is important to emphasize that even in the case of the only numerical mixture, the presence in one and same place (same mesh) of several fluids have to be taken into account. This will be formalized by the possibility for mass fractions to take all values between 0 and 1. This is not at odds with the equations that derive from the hypothesis of non-miscibility. One way of looking at things is to consider that there are two scales of observation: the physical scale at which one observes the separation of fluids, and the numerical scale, given by the fineness of the mesh, to which a mixture appears. In this work, mixtures are considered from the mathematical angle (both in the elaboration phase and during their study). In particular, Chapter 5 shows a result of model degeneration for a non-extended mixing zone (case of an interface): this justifies the use of models in the case of numerical mixing. All these models are based on the classical model of non-viscous compressible fluids recalled in Chapter 2. In Chapter 3, the central point of the elaboration of the class of models is

    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.

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

    Science.gov (United States)

    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. Frequently asked student questions were classified, but students also interacted with visual information through gestures and model manipulations. In an effort to characterize how much students used visualization during lecture or recitation, we developed observation rubrics to gather information about students' visualization artifacts and examined the effect instructors

    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.

    As a widely distributed and natural existing antioxidant, ferulic acid and its functions have been extensively studied in recent decades. In the present study, hypertrophic growth of fast skeletal myofibers was observed in adult zebrafish after ferulic acid administration for 30 days, being reflected in increased body weight, body mass index (BMI), and muscle mass, along with an enlarged cross-sectional area of myofibers. qRT-PCR analyses demonstrated the up-regulation of relative mRNA expression levels of myogenic transcriptional factors (MyoD, myogenin and serum response factor (SRF)) and their target genes encoding sarcomeric unit proteins involved in muscular hypertrophy (skeletal alpha-actin, myosin heavy chain, tropomyosin, and troponin I). Western blot analyses detected a higher phosphorylated level of zTOR (zebrafish target of rapamycin), p70S6K, and 4E-BP1, which suggests an enhanced translation efficiency and protein synthesis capacity of fast skeletal muscle myofibers. These changes in transcription and translation finally converge and lead to higher protein contents in myofibers, as confirmed by elevated levels of myosin heavy chain (MyHC), and an increased muscle mass. To the best of our knowledge, these findings have been reported for the first time in vivo and suggest potential applications of ferulic acid as functional food additives and dietary supplements owing to its ability to promote muscle growth.

    Test items created for dentistry examinations are often individually written by content experts. This approach to item development is expensive because it requires the time and effort of many content experts but yields relatively few items. The aim of this study was to describe and illustrate how items can be generated using a systematic approach. Automatic item generation (AIG) is an alternative method that allows a small number of content experts to produce large numbers of items by integrating their domain expertise with computer technology. This article describes and illustrates how three modeling approaches to item content-item cloning, cognitive modeling, and image-anchored modeling-can be used to generate large numbers of multiple-choice test items for examinations in dentistry. Test items can be generated by combining the expertise of two content specialists with technology supported by AIG. A total of 5,467 new items were created during this study. From substitution of item content, to modeling appropriate responses based upon a cognitive model of correct responses, to generating items linked to specific graphical findings, AIG has the potential for meeting increasing demands for test items. Further, the methods described in this study can be generalized and applied to many other item types. Future research applications for AIG in dental education are discussed.

    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.

    The evidence surrounding the value of workplace health promotion in positively influencing employees' health and wellbeing via changes to their health behaviours is growing. The aim of the study was to explore employers' views on the promotion of workplace health and wellbeing and the factors affecting these views. Using a qualitative phenomenological approach, 10 focus groups were conducted with employers selected from a range of industries and geographical locations within Western Australia. The total sample size was 79. Three factors were identified: employers' conceptualization of workplace health and wellbeing; employers' descriptions of (un)healthy workers and perceptions surrounding the importance of healthy workers; and employers' beliefs around the role the workplace should play in influencing health. Progress may be viable in promoting health and wellbeing if a multifaceted approach is employed taking into account the complex factors influencing employers' views. This could include an education campaign providing information about what constitutes health and wellbeing beyond the scope of occupational health and safety paradigms along with information on the benefits of workplace health and wellbeing aligned with perceptions relating to healthy and unhealthy workers.

  16. 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.

    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.

    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.

  9. Financial Analysis of Incentive Mechanisms to Promote Energy Efficiency: Case Study of a Prototypical Southwest Utility

    Energy Technology Data Exchange (ETDEWEB)

    Cappers, Peter; Goldman, Charles; Chait, Michele; Edgar, George; Schlegel, Jeff; Shirley, Wayne

    2009-03-04

    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

    2016-05-01

    Female inmate populations in the United States tend to be overweight, physically inactive, experience high stress, and have a history of nicotine and other drug dependence. Thus, they bear an elevated risk of cardiovascular (CV) disease than the general population. However, few evidence-based health interventions exist for this population. This study will test proof of concept, feasibility, and potential efficacy of a multiple health behavior change intervention that integrates CV-health promotion education delivered during a physical activity (PA) program (indoor cycling) tailored to this population. This study uses a quasi-experimental 2-group design with two measurement time-points: baseline and 8-week end of treatment. N=120 incarcerated women (18-59years of age) who are medically cleared for participation in PA will be enrolled. Indoor cycling instructors will be trained to deliver five health education topics over an 8-week period during twice-weekly cycling classes. Topics match the American Heart Association recommendations for CV health: (a) nutrition, (b) PA promotion, (c) weight management, (d) stress management, and (e) smoking cessation and relapse prevention. Modes of intervention include instructor advice, written materials and audio/video clips reviewed during class. CV-related and mental health measures will be assessed at both time-points. Results will guide a full scale efficacy study. Future research in this area has potential to impact the health of female inmates, a high-risk population. Moreover, this multiple health behavior change intervention model represents a community approach to health promotion that could generalize to other underserved populations who may benefit most from similar intervention efforts.

    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.

    2014-06-01

    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.

    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

    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

    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.

    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.

    2006-12-01

    Resiliency theory provides a conceptual framework for studying why some youth exposed to risk factors do not develop the negative behaviors they predict. The purpose of this study was to test compensatory and protective models of resiliency in a longitudinal sample of urban adolescents (80% African American). The data were from Years 1 (9th grade) and 4 (12th grade). The study examined effects of cumulative risk and promotive factors on adolescent polydrug use including alcohol, tobacco and marijuana. Cumulative measures of risk/promotive factors represented individual characteristics, peer influence, and parental/familial influences. After controlling for demographics, results of multiple regression of polydrug use support the compensatory model of resiliency both cross-sectionally and longitudinally. Promotive factors were also found to have compensatory effects on change in adolescent polydrug use. The protective model of resiliency evidenced cross-sectionally was not supported in longitudinal analysis. The findings support resiliency theory and the use of cumulative risk/promotive measures in resiliency research. Implications focused on utilizing multiple assets and resources in prevention programming are discussed.

    Improving infrastructure for walking and cycling is increasingly recommended as a means to promote physical activity, prevent obesity, and reduce traffic congestion and carbon emissions. However, limited evidence from intervention studies exists to support this approach. Drawing on classic epidemiological methods, psychological and ecological models of behavior change, and the principles of realistic evaluation, we have developed an applied ecological framework by which current theories about the behavioral effects of environmental change may be tested in heterogeneous and complex intervention settings. Our framework guides study design and analysis by specifying the most important data to be collected and relations to be tested to confirm or refute specific hypotheses and thereby refine the underlying theories.

    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.

    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.

    The study examines the reasons for the limited dissemination of solar lanterns in India. It uses ''diffusion of innovation'' framework to examine the dissemination process. The impact of the characteristics of solar lantern on dissemination and also the communication within the community about the product are examined. To understand the influence of the characteristics of solar lantern on dissemination and the information source used by adopters, a survey of 188 users across 15 locations is carried out. The study shows that the benefits promoted by the government programme for disseminating solar lantern are not the reasons for purchase in most cases. The results suggest that the emphasis on subsidy by the support programme shifts the focus to the cost of the solar lantern than its benefits. Contrary to expectation there is no significant difference in the profile of early and late adopters. The subsidy for solar lanterns and the targets set for government officials are the possible influence on the observed profile for adopter categories. The early majority who can afford the solar lantern and take up the innovation on its merits are expected to disseminate the innovation. The programme on the contrary not only fails to identify and promote to the early adopters, but focus on the disadvantaged groups. There are therefore no champions for the innovation and an absence of word-of-mouth communication. The information source is restricted to government agencies, while the potential user looks for evaluative information on the product from existing users. The application of ''diffusion of innovation'' framework to understand the dissemination process of solar lantern suggests reworking the support programmes designed to promote solar lanterns. The lessons can be extended to programmes designed for dissemination of other solar photovoltaic products. (author)

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.

    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

    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.

  16. Developmental song learning as a model to understand neural mechanisms that limit and promote the ability to learn.

    Science.gov (United States)

    London, Sarah E

    2017-11-20

    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.

    Full Text Available Abstract Background The National Institute of Clinical Excellence in the UK has recommended that the effectiveness of ongoing exercise referral schemes to promote physical activity should be examined in research trials. Recent empirical evidence in health care and physical activity promotion contexts provides a foundation for testing the utility of a Self Determination Theory (SDT-based exercise referral consultation. Methods/Design Design: An exploratory cluster randomised controlled trial comparing standard provision exercise on prescription with a Self Determination Theory-based (SDT exercise on prescription intervention. Participants: 347 people referred to the Birmingham Exercise on Prescription scheme between November 2007 and July 2008. The 13 exercise on prescription sites in Birmingham were randomised to current practice (n = 7 or to the SDT-based intervention (n = 6. Outcomes measured at 3 and 6-months: Minutes of moderate or vigorous physical activity per week assessed using the 7-day Physical Activity Recall; physical health: blood pressure and weight; health status measured using the Dartmouth CO-OP charts; anxiety and depression measured by the Hospital Anxiety and Depression Scale and vitality measured by the subjective vitality score; motivation and processes of change: perceptions of autonomy support from the advisor, satisfaction of the needs for competence, autonomy, and relatedness via physical activity, and motivational regulations for exercise. Discussion This trial will determine whether an exercise referral programme based on Self Determination Theory increases physical activity and other health outcomes compared to a standard programme and will test the underlying SDT-based process model (perceived autonomy support, need satisfaction, motivation regulations, outcomes via structural equation modelling. Trial registration The trial is registered as Current Controlled trials ISRCTN07682833.

    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 Health and Education Ministries of Brazil launched the Health in School Program (Programa Saúde na Escola - PSE in 2007. The purpose of the PSE is two-fold: articulate the actions of the education and health systems to identify risk factors and prevent them; and promote health education in the public elementary school system. In the health field, the self-regulation (SR construct can contribute to the understanding of life habits which can affect the improvement of individuals' health. This research aims to present a program that promotes SR in health (SRH. This program (PSRH includes topics on healthy eating and oral health from the PSE; it is grounded on the social cognitive framework and uses story tools to train 5th grade Brazilian students in SRH. The study consists of two phases. In Phase 1, teachers and health professionals participated in a training program on SRH, and in Phase 2, they will be expected to conduct an intervention in class to promote SRH. The participants were randomly assigned into three groups: the Condition I group followed the PSE program, the Condition II group followed the PSRH (i.e., PSE plus the SRH program, and the control group (CG did not enroll in either of the health promotion programs. For the baseline of the study, the following measures and instruments were applied: Body Mass Index (BMI, Simplified Oral Hygiene Index (OHI-S, Previous Day Food Questionnaire (PFDQ, and Declarative Knowledge for Health Instrument. Data indicated that the majority are eutrophic children, but preliminary outcomes showed high percentages of children that are overweight, obese and severely obese. Moreover, participants in all groups reported high consumption of ultraprocessed foods (e.g., soft drinks, artificial juices, and candies. Oral health data from the CI and CII groups showed a prevalence of regular oral hygiene, while the CG presented good oral hygiene. The implementation of both PSE and PSRH are expected to help

    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.

    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.

    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.

    In this study, we investigated the kinetics of gas hydrate formation in the presence of ionic liquid (IL). Hydroxyethyl-methyl-morpholinium chloride (HEMM-Cl) was chosen as a material for the promotion effect test. Phase equilibrium curve for CH 4 hydrate with aqueous IL solution was obtained and its induction time and consumed amount of CH 4 gas were also measured. Aqueous solutions containing 20-20,000 ppm of HEMM-Cl was prepared and studied at 70 bar and 274.15 K. To compare the measured results to those of the conventional promoter, sodium dodecyl sulfate was also tested at the same condition. Result showed that the hydrate equilibrium curve was shifted toward higher pressure and lower temperature region. In addition, the induction time on CH 4 hydrate formation in the presence of IL was not shown. The amount of consumed CH 4 was increased with the whole range of tested concentration of IL and the highest consumption of CH 4 happened at 1,000 ppm of HEMM-Cl. HEMM-Cl induced and enhanced the CH 4 hydrate formation with a small amount of addition. Obtained result is expected to be applied for the development of technologies such as gas storage and transport using gas hydrates

    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 study aims to find an effective method of expressing a message in public service ads by investigating whether or not a message framing type affects the outcome. Specifically, the study looks into the effects of messaging on organ donation by identifying how the type of message framing (positive vs. negative) and appeal type (rational vs. emotional) affect the attitude and behavioural intention of the consumer. The individual characteristics of each subject such as altruistic mind, level of self-monitoring and issue involvement were selected as intermediate variables that may affect the impact of a message. The study therefore tries to establish a proposition that can be used to generate an effective promotional message on organ donation in a systematic way. © The Author (2014).

    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 P<.001). HH compliance sustained from 83.7% (473/565) in 2013 to 86.7% (589/679) in 2014 (P=.13) among all HCWs. Facebook had the highest connection rate in the HH video campaign. The use of novel social media such as Facebook should be considered for future programs that promote hand hygiene and other healthy behaviors.

    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.

    2018-06-01

    Full Text Available Because of the comprehensiveness and urgency of environmental challenges, every stakeholder needs to be engaged in reducing environmental impacts. The healthcare sector has rarely been studied, despite its intense effects on the environment, particularly through generating various forms of hazardous waste and intensively consuming energy and water. Many healthcare facilities exist in South Korea, and every citizen frequently visits hospitals thanks to the convenient system. To reduce the environmental impacts of the healthcare sector, the South Korean government has implemented various policy measures aimed at promoting environmental management in that sector. This study evaluated the eco-efficiencies of 21 hospitals from 2012 to 2015 using data envelopment assessment (DEA, used the analytical hierarchy process (AHP to analyze hospital staff members’ answers to a questionnaire asking about the relative importance and performance of individual environmental management tasks, and also identified environmental management tasks that should be prioritized by building an importance-performance analysis (IPA matrix using those questionnaire responses. This study found that eco-efficiencies have improved during the period, and that mandatory policy measures were more effective than voluntary agreements for improving eco-efficiency. This implies that rigorous reporting and monitoring should be implemented along with any voluntary agreement. In addition, this study found that the top priorities are “establishment of vision and strategy for environmental management” and “organization of task team for environmental management and task assignment”. This shows the necessity of additional policy measures, such as training or consulting to promote the priorities. In addition to policy recommendations for diffusing environmental management in the South Korean healthcare sector, the methodological approach sheds light for researchers interested in

    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.

    The global burden of mental illness is high and opportunities for promoting mental health are neglected in most parts of the world. Many people affected by mental illness live in developing countries, where treatment and care options are limited. In this context, primary health care (PHC) programs can indirectly promote mental health by addressing its determinants i.e. by enhancing social unity, minimising discrimination and generating income opportunities. The objectives of this study were to: 1. Describe concepts of mental health and beliefs about determinants of mental health and illness among women involved with a PHC project in rural Maharashtra, India; 2. Identify perceived mental health problems in this community, specifically depression, suicide and violence, their perceived causes, and existing and potential community strategies to respond to them and; 3. Investigate the impact of the PHC program on individual and community factors associated with mental health We undertook qualitative in-depth interviews with 32 women associated with the PHC project regarding: their concepts of mental health and its determinants; suicide, depression and violence; and the perceived impact of the PHC project on the determinants of mental health. The interviews were taped, transcribed, translated and thematically analysed. Mental health and illness were understood by these women to be the product of cultural and socio-economic factors. Mental health was commonly conceptualised as an absence of stress and the commonest stressors were conflict with husbands and mother-in-laws, domestic violence and poverty. Links between empowerment of women through income generation and education, reduction of discrimination based on caste and sex, and promotion of individual and community mental health were recognised. However, mental health problems such as suicide and violence were well-described by participants. While it is essential that affordable, accessible, appropriate treatments and

    Full Text Available Bicyclol, an antihepatitis drug developed by Chinese scientists, has been shown to prevent the malignant transformation induced by 3-methylcholanthrene and 12-O-tetradecanoylphorbol-13-acetate in WB-F344 rat liver epithelial cells. This study provides further evidence on its role as a chemopreventive agent in experimental mice with diethylnitrosamine- (DEN- initiated and phenobarbital- (PB- promoted liver carcinoma. Liver tissue and serum were collected. In the two-stage model of hepatocarcinogenesis in mice, oral administration of bicyclol (100, 200 mg/kg before DEN injection showed significant reduction in the incidence of hepatocellular foci, nodules, or carcinoma. Histopathological examination revealed that there was no hepatocellular carcinoma (HCC and hepatoma formation in the mice pretreated with bicyclol (200 mg/kg at week 20, while the mice treated with DEN/PB developed 33.3% HCC and 55.6% hepatoma. Furthermore, the serum levels of alanine aminotransferase (ALT, alkaline phosphatase (ALP, and α-fetal protein (AFP in serum significantly increased in the DEN/PB model group in comparison with the control group. Pretreatment with bicyclol showed a marked reduction in the above condition. Bicyclol also decreased the expression of AFP and proliferating cell nuclear antigen level in the liver tissue and attenuated the decrease in body weight. In this study, we also found that 10 weeks after stopping the administration of PB and drugs, the control and bicyclol-treated (200 mg/kg animals showed no HCC and hepatoma formation at the time of termination whereas DEN/PB-induced mice developed 100% hepatoma and 50% HCC. These results further indicate that bicyclol has the chemopreventive potential for liver carcinogenesis induced by carcinogens.

    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.

    Stroke is a major public health threat globally. Psychosocial well-being may be affected following stroke. Depressive symptoms, anxiety, general psychological distress and social isolation are prevalent. Approximately one third report depressive symptoms and 20% report anxiety during the first months or years after the stroke. Psychosocial difficulties may impact significantly on long-term functioning and quality of life, reduce the effects of rehabilitation services and lead to higher mortality rates. The aim of the study is to evaluate the effect of a previously developed and feasibility tested dialogue-based psychosocial intervention aimed at promoting psychosocial well-being and coping following stroke among stroke survivors with and without aphasia. The study will be conducted as a multicenter, randomized, single blind controlled trial with one intervention and one control arm. It will include a total of 330 stroke survivors randomly allocated into either an intervention group (dialogue-based intervention to promote psychosocial well-being) or a control group (usual care). Participants in the intervention group will receive eight individual sessions of supported dialogues in their homes during the first six months following an acute stroke. The primary outcome measure will be psychosocial well-being measured by the General Health Questionnaire (GHQ). Secondary outcome measures will be quality of life (SAQoL), sense of coherence (SOC), and depression (Yale). Process evaluation will be conducted in a longitudinal mixed methods study by individual qualitative interviews with 15-20 participants in the intervention and control groups, focus group interviews with the intervention personnel and data collectors, and a comprehensive analysis of implementation fidelity. The intervention described in this study protocol is based on thorough development and feasibility work, guided by the UK medical research council framework for developing and testing complex

    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.

    To examine the impact of a skin cancer prevention intervention that promoted sunless tanning as a substitute for sunbathing. Randomized controlled trial. Public beaches in Massachusetts. Women (N = 250) were recruited to participate in the study during their visit to a public beach. Intervention The intervention included motivational messages to use sunless tanning as an alternative to UV tanning, instructions for proper use of sunless tanning products, attractive images of women with sunless tans, a free trial of a sunless tanning product, skin cancer education, and UV imaging. The control participants completed surveys. The primary outcome was sunbathing 2 months and 1 year after the intervention. Secondary outcomes included sunburns, sun protection use, and sunless tanning. At 2 months, intervention participants reduced their sunbathing significantly more than did controls and reported significantly fewer sunburns and greater use of protective clothing. At 1 year, intervention participants reported significant decreases in sunbathing and increases in sunless tanning relative to control participants but no differences in the other outcomes. This intervention, which promoted sunless tanning as an alternative to UV tanning, had a short-term effect on sunbathing, sunburns, and use of protective clothing and a longer-term effect on sunbathing and sunless tanning. clinicaltrials.gov Identifier: NCT00403377.

    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.

    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.

    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 study assessed 54 advertisements of 145 different drugs, published over one year (from December 2011 to November 2012) in an Indian medical journal, circulated widely mainly among general practitioners (GPs). The ethical guidelines of the World Health Organization (WHO) and Organisation of Pharmaceutical Producers of India (OPPI) for medicinal drug promotion were applied. The brand name was mentioned in all advertisements (100% compliance both with the WHO and OPPI criteria) and the names of the active ingredients were also mentioned in 128 (90.14%) advertisements. However, major adverse drug reactions were mentioned in only two advertisements (1.37%); precautions, contraindications and warnings in only two (1.37%); and major interactions in only one (0.68%). Only three advertisements (2.06%) were well substantiated with references. To ensure the ethical promotionof drugs among GPs, journals must introduce compulsory review and appraisal of promotional advertisements by a dedicated review board, including at least one member trained in pharmacology and one representative from the medical division of a pharmaceutical company.

    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.

    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.

    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.

    2011-07-01

    We have shown previously that distinct Mena isoforms are expressed in invasive and migratory tumor cells in vivo and that the invasion isoform (Mena(INV)) potentiates carcinoma cell metastasis in murine models of breast cancer. However, the specific step of metastatic progression affected by this isoform and the effects on metastasis of the Mena11a isoform, expressed in primary tumor cells, are largely unknown. Here, we provide evidence that elevated Mena(INV) increases coordinated streaming motility, and enhances transendothelial migration and intravasation of tumor cells. We demonstrate that promotion of these early stages of metastasis by Mena(INV) is dependent on a macrophage-tumor cell paracrine loop. Our studies also show that increased Mena11a expression correlates with decreased expression of colony-stimulating factor 1 and a dramatically decreased ability to participate in paracrine-mediated invasion and intravasation. Our results illustrate the importance of paracrine-mediated cell streaming and intravasation on tumor cell dissemination, and demonstrate that the relative abundance of Mena(INV) and Mena11a helps to regulate these key stages of metastatic progression in breast cancer cells.

    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.

    During the period 1997-2000 a technical assistance project to build capacity for community-based health promotion was implemented in seven cities and one province in China. The technical assistance project formed part of a much larger World Bank supported program to improve disease prevention capabilities in China, commonly known as Health VII. The technical assistance project was funded by the Australian Agency for International Development. It was designed to develop capacity within the Ministry of Health (MOH) and the cities and province in the management of community-based health promotion projects, as well as supporting institutional development and public health policy reform. There are some relatively unique features of this technical assistance which helped shape its implementation and impact. It sought to provide the Chinese MOH and the cities and province with an introduction to comprehensive health promotion strategies, in contrast to the more limited information, education and communication strategies. The project was provided on a continuing basis over 3 years through a single institution, rather than as a series of ad hoc consultancies by individuals. Teaching and learning processes were developmental, leading progressively to a greater degree of local Chinese input and management to ensure sustainability and maintenance of technical support for the project. Based on this experience, this paper presents a model for capacity building projects of this type. It describes the education, training and planning activities that were the key inputs to the project, as well as the limited available evidence on the impact of the project. It describes how the project evolved over time to meet the changing needs of the participants, specifically how the content of the project shifted from a risk-factor orientation to a settings-based focus, and the delivery of the project moved from an expert-led approach to a more participatory, problem based learning approach.

    The National Uranium Resource Evaluation (NURE) Program has sponsored uranium deposit model studies by Bendix Field Engineering Corporation (Bendix), the US Geological Survey (USGS), and numerous subcontractors. This paper deals only with models from the following six reports prepared by Samuel S. Adams and Associates: GJBX-1(81) - Geology and Recognition Criteria for Roll-Type Uranium Deposits in Continental Sandstones; GJBX-2(81) - Geology and Recognition Criteria for Uraniferous Humate Deposits, Grants Uranium Region, New Mexico; GJBX-3(81) - Geology and Recognition Criteria for Uranium Deposits of the Quartz-Pebble Conglomerate Type; GJBX-4(81) - Geology and Recognition Criteria for Sandstone Uranium Deposits in Mixed Fluvial-Shallow Marine Sedimentary Sequences, South Texas; GJBX-5(81) - Geology and Recognition Criteria for Veinlike Uranium Deposits of the Lower to Middle Proterozoic Unconformity and Strata-Related Types; GJBX-6(81) - Geology and Recognition Criteria for Sandstone Uranium Deposits of the Salt Wash Type, Colorado Plateau Province. A unique feature of these models is the development of recognition criteria in a systematic fashion, with a method for quantifying the various items. The recognition-criteria networks are used in this paper to illustrate the various types of deposits

    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

    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.

    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.

    To systematically review studies of health promotion intervention in the police force. Four databases were searched for articles reporting on prepost single and multigroup studies in police officers and trainees. Data were extracted and bias assessed to evaluate study characteristics, intervention design and the impact of interventions on health. Database searching identified 25 articles reporting on 21 studies relevant to the aims of this review. Few studies (n=3) were of long duration (≥6 months). Nine of 21 studies evaluated structured physical activity and/or diet programmes only, 5 studies used education and behaviour change support-only interventions, 5 combined structured programmes with education and behaviour change support, and 2 studies used computer prompts to minimise sedentary behaviour. A wide array of lifestyle behaviour and health outcomes was measured, with 11/13 multigroup and 8/8 single-group studies reporting beneficial impacts on outcomes. High risk of bias was evident across most studies. In those with the lowest risk of bias (n=2), a large effect on blood pressure and small effects on diet, sleep quality, stress and tobacco use, were reported. Health promotion interventions can impact beneficially on health of the police force, particularly blood pressure, diet, sleep, stress and tobacco use. Limited reporting made comparison of findings challenging. Combined structured programmes with education and behaviour change support and programmes including peer support resulted in the most impact on health-related outcomes. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

  12. Hydrogen improves glycemic control in type1 diabetic animal model by promoting glucose uptake into skeletal muscle.

    Haruka Amitani

    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.

    Halko, Sajanee; Kientz, Julie A.

    Though a variety of persuasive health applications have been designed with a preventive standpoint toward diseases in mind, many have been designed largely for a general audience. Designers of these technologies may achieve more success if applications consider an individual's personality type. Our goal for this research was to explore the relationship between personality and persuasive technologies in the context of health-promoting mobile applications. We conducted an online survey with 240 participants using storyboards depicting eight different persuasive strategies, the Big Five Inventory for personality domains, and questions on perceptions of the persuasive technologies. Our results and analysis revealed a number of significant relationships between personality and the persuasive technologies we evaluated. The findings from this study can guide the development of persuasive technologies that can cater to individual personalities to improve the likelihood of their success.

    2011-03-01

    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.

    Full Text Available Homeobox genes direct the anterior-posterior axis of the body plan in eukaryotic organisms. Promoter regions upstream of the Hox genes jumpstart the transcription process. CpG islands found within the promoter regions can cause silencing of these promoters. The locations of the promoter regions and the CpG islands of Homeo sapiens sapiens (human, Pan troglodytes (chimpanzee, Mus musculus (mouse, and Rattus norvegicus (brown rat are compared and related to the possible influence on the specification of the mammalian body plan. The sequence of each gene in Hox clusters A-D of the mammals considered were retrieved from Ensembl and locations of promoter regions and CpG islands predicted using Exon Finder. The predicted promoter sequences were confirmed via BLAST and verified against the Eukaryotic Promoter Database. The significance of the locations was determined using the Kruskal-Wallis test. Among the four clusters, only promoter locations in cluster B showed significant difference. HOX B genes have been linked with the control of genes that direct the development of axial morphology, particularly of the vertebral column bones. The magnitude of variation among the body plans of closely-related species can thus be partially attributed to the promoter kind, location and number, and gene inactivation via CpG methylation.

    Health professionals are encouraged to play a part in reducing the health risks of physical inactivity. Little is known of the physical activity promotion practice behaviours of podiatrists. We performed 20 semi-structured interviews with purposefully selected podiatrists to explore their physical activity promotion attitudes, beliefs, knowledge and practice. Transcribed interviews were coded using an iterative thematic approach to identify major themes and salient beliefs. Overall, the participants had a positive attitude to physical activity promotion, considering it a normal part of their role. They saw their role as giving information, encouraging activity and making recommendations, however in practice they were less inclined to follow up on recommendations, monitor activity levels or document the process. Their approach was generally opportunistic, informal and unstructured and the content of assessment and promotion dependent upon the presenting patient's condition. Advice tended to be tailored to the patient's capabilities and interests. They considered there are opportunities to promote physical activity during regular consultations, however, were more likely to do so in patients with chronic diseases such as diabetes. Main barriers to physical activity promotion included unreceptive and unmotivated patients as well as a lack of time, skills and resources. Physical activity promotion appears feasible in podiatry practice in terms of opportunity and acceptability to practitioners, but there is scope for improvement. Strategies to improve promotion need to consider the major issues, barriers and opportunities as well as provide a more structured approach to physical activity promotion by podiatrists.

  19. Promoting community socio-ecological sustainability through technology: A case study from Chile

    2017-12-01

    The importance of community learning in effecting social change towards ecological sustainability has been recognised for some time. More recently, the use of Information and Communication Technology (ICT) tools to promote socio-ecological sustainability has been shown to have potential in community education for sustainable development (ESD). The effective design and use of technology for community learning implies an understanding of a range of cross-dimensional factors including: socio-cultural characteristics and needs of the target audience; considerations of available and culturally responsive types of technology; and non-formal pedagogical ESD strategies for community empowerment. In addition, both technology itself and social communities are dynamically evolving and complex entities. This article presents a case study which evaluated the potential of ICT for promoting ecological literacy and action competence amongst community members in southern Chile. The case study addressed the ecological deterioration of a lake, which is having deep social, economic, recreational and cultural implications locally. The authors' research involved developing a theoretical framework for the design, implementation and use of ICT for community learning for sustainability. The framework was based on key ideas from ESD, ICT and community education, and was underpinned by a systems thinking approach to account for the dynamism and complexity of such settings. Activity theory provided a frame to address overarching socio-cultural elements when using technology as a mediating tool for community learning. The authors' findings suggest that the use of an ICT tool, such as a website, can enhance ecological literacy in relation to a local socio-ecological issue.

    Full Text Available Abstract Background Professional truck drivers, as other shift workers, have been identified as a high-risk group for various health conditions including cardiovascular disease, obesity, diabetes, sleep apnoea and stress. Mobile health technologies can potentially improve the health and wellbeing of people with a sedentary lifestyle such as truck drivers. Yet, only a few studies on health promotion interventions related to mobile health technologies for truck drivers have been conducted. We aimed to explore professional truck drivers’ views on health promotion delivered via mobile health technologies such as wearable devices. Methods We conducted a phenomenological qualitative study, consisting of four semi-structured focus groups with 34 full-time professional truck drivers in the UK. The focus groups were audio-taped, transcribed verbatim and analysed using thematic content analysis. We discussed drivers’ perceptions of their health, lifestyle and work environment, and their past experience and expectations from mobile health technologies. Results The participants viewed their lifestyle as unhealthy and were aware of possible consequences. They expressed the need and wish to change their lifestyle, yet perceived it as an inherent, unavoidable outcome of their occupation. Current health improvement initiatives were not always aligned with their working conditions. The participants were generally willing to use mobile health technologies such as wearable devices, as a preventive measure to avoid prospect morbidity, particularly cardiovascular diseases. They were ambivalent about privacy and the risk of their employer’s monitoring their clinical data. Conclusions Wearable devices may offer new possibilities for improving the health and wellbeing of truck drivers. Drivers were aware of their unhealthy lifestyle. They were interested in changing their lifestyle and health. Drivers raised concerns regarding being continuously monitored by

  1. Sales promotions and food consumption.

    Sales promotions are widely used to market food to adults, children, and youth. Yet, in contrast to advertising, practically no attention has been paid to their impacts on dietary behaviors, or to how they may be used more effectively to promote healthy eating. This review explores the available literature on the subject. The objective is to identify if and what literature exists, examine the nature of this literature, and analyze what can be learned from it about the effects of sales promotions on food consumption. The review finds that while sales promotions lead to significant sales increases over the short-term, this does not necessarily lead to changes in food-consumption patterns. Nevertheless, there is evidence from econometric modeling studies indicating that sales promotions can influence consumption patterns by influencing the purchasing choices of consumers and encouraging them to eat more. These effects depend on the characteristics of the food product, sales promotion, and consumer. The complexity of the effects means that sales promotions aiming to encourage consumption of nutritious foods need to be carefully designed. These conclusions are based on studies that use mainly sales data as a proxy for dietary intake. The nutrition (and economics) research communities should add to this existing body of research to provide evidence on the impact of sales promotions on dietary intake and related behaviors. This would help support the development of a sales promotion environment conducive to healthy eating.

    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

    Increased plasma levels of bilirubin have been reported in rat models and patients with alcoholic liver disease (ALD). The constitutive androstane receptor (CAR) is a known xenobiotic receptor, which induces the detoxification and transport of bilirubin. In the present study, the bilirubin transport regulatory mechanisms, and the role of CAR activation in hepatic and extrahepatic bilirubin clearance were investigated in a murine model of ALD. The mice were fed a Lieber-DeCarli ethanol diet or an isocaloric control diet for 4 weeks, followed by the administration of CAR agonists, 1,4-bis-[2‑(3,5-dichlorpyridyloxy)]benzene (TCPOBOP) and phenobarbital (PB), and their vehicles to examine the effect of the pharmacological activation of CAR on serum levels of bilirubin and on the bilirubin clearance pathway in ALD by serological survey, western blotting and reverse transcription‑quantitative polymerase chain reaction. The results showed that chronic ethanol ingestion impaired the nuclear translocation of CAR, which was accompanied by elevated serum levels of bilirubin, suppression of the expression of hepatic and renal organic anion transporting polypeptide (OATP) 1A1 and hepatic multidrug resistance‑associated protein 2 (MRP2), and induction of the expression of UDP-glucuronosyltransferase (UGT) 1A1. The activation of CAR by TCPOBOP and PB resulted in downregulation of the serum levels of bilirubin followed by selective upregulation of the expression levels of OATP1A1, OATP1A4, UGT1A1 and MRP2 in ALD. These results revealed the bilirubin transport regulatory mechanisms and highlighted the importance of CAR in modulating the bilirubin clearance pathway in the ALD mouse model.

    Folate is essential for nucleotide synthesis, DNA replication, and methyl group supply. Low-folate status has been associated with increased risks of several cancer types, suggesting a chemopreventive role of folate. However, recent findings on giving folic acid to patients with a history of colorectal polyps raise concerns about the efficacy and safety of folate supplementation and the long-term health effects of folate fortification. Results suggest that undetected precursor lesions may progress under folic acid supplementation, consistent with the role of folate role in nucleotide synthesis and cell proliferation. To better understand the possible trade-offs between the protective effects due to decreased mutation rates and possibly concomitant detrimental effects due to increased cell proliferation of folic acid, we used a biologically based mathematical model of colorectal carcinogenesis. We predict changes in cancer risk based on timing of treatment start and the potential effect of folic acid on cell proliferation and mutation rates. Changes in colorectal cancer risk in response to folic acid supplementation are likely a complex function of treatment start, duration, and effect on cell proliferation and mutations rates. Predicted colorectal cancer incidence rates under supplementation are mostly higher than rates without folic acid supplementation unless supplementation is initiated early in life (before age 20 years). To the extent to which this model predicts reality, it indicates that the effect on cancer risk when starting folic acid supplementation late in life is small, yet mostly detrimental. Experimental studies are needed to provide direct evidence for this dual role of folate in colorectal cancer and to validate and improve the model predictions.

  5. Modeling routes of chronic wasting disease transmission: Environmental prion persistence promotes deer population decline and extinction

    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.

    The ultimate goal of the project PROMOCAP was the development and study of electrochemical promotion systems for the capture and valorization of CO 2 in combustion flue gases. To achieve this objective, electrocatalysts consisting of tubes or monoliths of solid electrolyte (K-βAl 2 O 3 or YSZ), coated by the corresponding active metal (Pt, Pd, Ni, Cu, Fe-TiO 2 , Pt-Ru - C, Pt-C, etc.), were prepared using both conventional (painting) and improved (dip-coating, electroless or spray-coating) procedures. Both physico-chemical and volt amperometric characterization of the electrocatalysts was carried out both as prepared and after use in electro promoted CO 2 capture and valorization processes (study of chemisorption, reaction, inhibition, deactivation phenomena, etc.). Pilot plant studies were carried out under realistic conditions for identifying the best electro catalyst and the operating conditions more suitable for CO 2 electro promoted capture and valorization. Finally, the electrocatalysts identified as the most promising for electro promoted CO 2 capture (Pt/K-βAl 2 O 3 ) and valorization (Cu/K-βAl 2 O 3 ) were prepared using the developed optimized procedures and their behavior over multiple cycles of electro promoted CO 2 capture and in long term operation against electro promoted CO 2 hydrogenation, respectively, was studied under real or realistic conditions.

    In view of increased life expectancy the risk for disturbed integrity of genetic information increases. This inevitably holds the implication for higher incidence of age-related diseases leading to considerable cost increase in health care systems. To develop preventive strategies it is crucial to evaluate external and internal noxae as possible threats to our DNA. Especially the interplay of DNA damage response (DDR) and DNA repair (DR) mechanisms needs further deciphering. Moreover, there is a distinct need for alternative in vivo test systems for basic research and also risk assessment in toxicology. Especially the evaluation of combinational toxicity of environmentally present genotoxins and adverse effects of clinically used DNA damaging anticancer drugs is a major challenge for modern toxicology. This review focuses on the applicability of Caenorhabditis elegans as a model organism to unravel and tackle scientific questions related to the biological consequences of genotoxin exposure and highlights methods for studying DDR and DR. In this regard large-scale in vivo screens of mixtures of chemicals and extensive parallel sequencing are highlighted as unique advantages of C. elegans. In addition, concise information regarding evolutionary conserved molecular mechanisms of the DDR and DR as well as currently available data obtained from the use of prototypical genotoxins and preferential read-outs of genotoxin testing are discussed. The use of established protocols, which are already available in the community, is encouraged to facilitate and further improve the implementation of C. elegans as a powerful genetic model system in genetic toxicology and biomedicine.

    Several studies using transgenic mouse models of familial amyotrophic lateral sclerosis (ALS) have reported a life span increase in exercised animals, as long as animals are submitted to a moderate-intensity training protocol. However, the neuroprotective potential of exercise is still questionable. To gain further insight into the cellular basis of the exercise-induced effects in neuroprotection, we compared the efficiency of a swimming-based training, a high-frequency and -amplitude exercise that preferentially recruits the fast motor units, and of a moderate running-based training, that preferentially triggers the slow motor units, in an ALS mouse model. Surprisingly, we found that the swimming-induced benefits sustained the motor function and increased the ALS mouse life span by about 25 days. The magnitude of this beneficial effect is one of the highest among those induced by any therapeutic strategy in this disease. We have shown that, unlike running, swimming significantly delays spinal motoneuron death and, more specifically, the motoneurons of large soma area. Analysis of the muscular phenotype revealed a swimming-induced relative maintenance of the fast phenotype in fast-twitch muscles. Furthermore, the swimming programme preserved astrocyte and oligodendrocyte populations in ALS spinal cord. As a whole, these data are highly suggestive of a causal relationship not only linking motoneuron activation and protection, but also motoneuron protection and the maintenance of the motoneuron surrounding environment. Basically, exercise-induced neuroprotective mechanisms provide an example of the molecular adaptation of activated motoneurons.

    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 For approximately twenty-years, Web-enhanced learning environments have been popular in higher education. Much research has examined how best practices can integrate technology, pedagogical theories, and resources to enhance learning. Numerous studies of hybrid teaching have revealed mostly positive effects. Yet, very little research has examined how to teach a successful physical activity course using a hybrid format. Review of the literature: We reviewed the research regarding the design and implementation of a Web-enhanced physical activity course in a college population using pedagogical principles of learning and the10 self-determination theory. Method: Data were collected from students at the beginning and end of the course. The hybrid course consisted of completing weekly online activities, and selecting and participating in a face-to-face physical activity based on student’s choice. Conclusion: The authors propose this template as a model to assist faculty in designing and implementing a blended physical activity course.

    Full Text Available The aim of this article is to enhance the understanding of how design companies perceive the benefits of Building Information Modeling (BIM technologies application. BIM is recognized in the literature as a (potentially powerful driver leading the construction sector towards sustainability. However, for design companies, the choice to invest in BIM technologies is basically an economic one. Specifically, a design company assesses economic benefits and efficiency improvements thanks to the application of BIM technologies. The article discusses the return on investments (ROI in BIM technologies and reviews ROI calculation methodologies proposed by other authors. In order to evaluate BIM return on investment correctly practical ROI calculations are carried out. Appropriate methods, together with the relevant variables for ROI calculation, are developed. The study allows for adjusting the calculation method making it more accurate and understandable using the Autodesk Revit based ROI calculation of the first year.

    Full Text Available Peripheral artery disease (PAD currently affects approximately 27 million patients in Europe and North America, and if untreated, may progress to the stage of critical limb ischemia (CLI, which has implications for amputation and potential mortality. Unfortunately, few therapies exist for treating the ischemic skeletal muscle in these conditions. Biomaterials have been used to increase cell transplant survival as well as deliver growth factors to treat limb ischemia; however, existing materials do not mimic the native skeletal muscle microenvironment they are intended to treat. Furthermore, no therapies involving biomaterials alone have been examined. The goal of this study was to develop a clinically relevant injectable hydrogel derived from decellularized skeletal muscle extracellular matrix and examine its potential for treating PAD as a stand-alone therapy by studying the material in a rat hindlimb ischemia model. We tested the mitogenic activity of the scaffold’s degradation products using an in vitro assay and measured increased proliferation rates of smooth muscle cells and skeletal myoblasts compared to collagen. In a rat hindlimb ischemia model, the femoral artery was ligated and resected, followed by injection of 150 µL of skeletal muscle matrix or collagen 1 week post-injury. We demonstrate that the skeletal muscle matrix increased arteriole and capillary density, as well as recruited more desmin-positive and MyoD-positive cells compared to collagen. Our results indicate that this tissue-specific injectable hydrogel may be a potential therapy for treating ischemia related to PAD, as well as have potential beneficial effects on restoring muscle mass that is typically lost in CLI.

    A numerical model has been developed to study the factors which control the height of the benthic boundary layer in the deep ocean and the dispersion of a tracer within and directly above the layer. This report covers tracer clouds of horizontal scales of 10 to 100 km. The dispersion of a tracer has been studied in two ways. Firstly, a number of particles have been introduced into the flow. The trajectories of these particles provide information on dispersion rates. For flow conditions similar to those observed in the abyssal N.E. Atlantic the diffusivity of a tracer was found to be 5 x 10 6 cm 2 s -1 for a tracer within the boundary layer and 8 x 10 6 cm 2 s -1 for a tracer above the boundary layer. The results are in accord with estimates made from current meter measurements. The second method of studying dispersion was to calculate the evolution of individual tracer clouds. Clouds within and above the benthic boundary layer often show quite different behaviour from each other although the general structure of the clouds in the two regions were found to have no significant differences.

    The German Renewable Energy Act (EEG) has been very successful in promoting the deployment of renewable electricity technologies in Germany. The increasing share of EEG power in the generation portfolio, increasing amounts of fluctuating power generation, and the growing European integration of power markets governed by competition calls for a re-design of the EEG. In particular, a more efficient system integration and commercial integration of the EEG power is needed to, e.g. better matching feed-in to demand and avoiding stress on electricity grids. This article describes three different options to improve the EEG by providing appropriate incentives and more flexibility to the promotion mechanism and the quantitative compensation scheme without jeopardising the fast deployment of renewable energy technologies. In the 'Retailer Model', it becomes the responsibility of the end-use retailers to adapt the EEG power to the actual demand of their respective customers. The 'Market Mediator Model' establishes an independent market mediator responsible to market the renewable electricity. This model is the primary choice when new market entrants are regarded as crucial for the better integration of renewable energy and enhanced competition. The 'Optional Bonus Model' relies more on functioning markets since power plant operators can alternatively choose to market the generated electricity themselves with a premium on top of the market price instead of a fixed price

    Highlights: • Yttrium 4-nitrocinnamate is a new corrosion inhibitor alternative to chromate technologies. • The inhibition performance is increased with increase of the inhibitor concentration. • Yttrium 4-nitrocinnamate mitigates corrosion by promoting random distribution of minor anodes. • Yttrium 4-nitrocinnamate is a good candidate for substitution of chromate inhibitors. - Abstract: Yttrium 4-nitrocinnamate (Y(4-NO{sub 2}Cin){sub 3}) was added to an aqueous chloride solution and studied as a possible corrosion inhibition system. Electrochemical techniques and surface analysis have been powerful tools to better understand the corrosion and inhibition processes of mild steel in 0.01 M NaCl solution. A combination of scanning electron microscopy (SEM), atomic force microscopy (AFM), attenuated total reflectance Fourier transform infrared spectroscopy (ATR-FTIR), X-ray photoelectron spectroscopy (XPS), Potentiodynamic polarization (PD), electrochemical impedance spectroscopy (EIS) and wire beam electrode (WBE) techniques was found to be useful in the characterization of this system. The result indicated that Y(4-NO{sub 2}Cin){sub 3} is able to effectively inhibit corrosion at a low concentration of 0.45 mM. Surface analysis clearly shows that the surface of steel coupons exposed to Y(4-NO{sub 2}Cin){sub 3} solution remained uniform and smooth, whereas the surface of steel coupons exposed to solution without inhibitor addition was severely corroded. The results suggest that Y(4-NO{sub 2}Cin){sub 3} behaves as a mixed inhibitor and mitigates corrosion by promoting random distribution of minor anodes. These are attributed to the formation of metal species bonding to the 4-nitrocinnamate component and hydrolysis of the Y(4-NO{sub 2}Cin){sub 3} to form oxide/hydroxides as a protective film layer.
