Full Text Available Background: Effective tourism management in the field of sports tourism requires an understanding of differences in socioeconomic characteristics both within and between different market segments. Objective: In the broad tourism market demographic characteristics have been extensively analyzed for differences in destination choices, however little is known about demographic factors affecting sport tourists' decisions. Methods: A sample of Slovenian sports tourists was analyzed using data from a comprehensive survey of local and outbound tourist activity conducted by the Statistical Office of the Republic of Slovenia in 2008. After data weighting the information for 353,783 sports related trips were available for analysis. The research model adopted suggests that four socio-demographic characteristics (gender, age, level of education and income significantly affect a tourist's choice of sports related travel either locally within Slovenia or to a foreign country. Furthermore the destination (local or foreign has an influence on the choice of the type of accommodation selected and the tourist's total expenditure for the trip. For testing the first part of our model (the socio-demographic characteristics effects a linear regression was used, and for the final part of the model (the selection of accommodation type and travel expenditure t-test were applied. Results: The result shows the standardized β regression coefficients are all statistically significant at the .001 level for the tested socio-demographic characteristics and also the overall regression model was statistically significant at .001 level. Conclusions: With these results the study confirmed that all the selected socio-demographic characteristics have a significant influence on the sport-active tourist when choosing between a domestic and foreign tourism destination which in turn affect the type of accommodation chosen and the level of expenditure while travelling.

2016-11-01

Full Text Available The author analyzes researches on the study of affective disorders in arterial hypertension (AH. It is noted that AH at the present stage is considered as one of the factors of cognitive dysfunction. The article emphasizes that the analysis of comorbid relations of depression and hypertension is hardly possible without the study of affective and cardiovascular disorders at the clinical level, taking into account their dynamic characteristics and key features of the course of depressive states in general. The author considers the features of the current: post-stroke depressions, nosogenic depressions of anxious and anxious-hypochondriacally types, anxiety-phobic disorders, comorbid panic disorders, protracted depression with traits of endoreactive dysthymia, hypochondriacal disorders, panic attacks, and the like in patients with arterial hypertension. Some features of affective disorders are revealed in patients with cardiovascular disorders. It is emphasized that the increase in the effectiveness of treatment of mental disorders in patients with hypertensive encephalopathy can be solved by improving the methods of early diagnosis, developing additional screening and monitoring diagnostic tools using it in an interdisciplinary approach.

Productive Love Promotion Via Affective Technology: An Approach Based On Social Psychology And Philosophy

Directory of Open Access Journals (Sweden)

Ramon Solves Pujol

2010-01-01

Full Text Available This paper proposes the use of social psychological and philosophical foundations for designing affective technology that promotes the experience of love. The adopted theoretical basis is the concept of productive love, which is heavily based on Enrich Fromm but also includes theories and scientific findings of numerous psychoanalysts, social psychologists, and philosophers. We conducted a review of the theory about the nature of love and found that social psychological and philosophical approaches differ regarding peoples' understandings. The findings were used to elaborate eight principles of productive love. Based on these principles, we derived criteria for designing affective technology when the objective is to promote productive love. We reviewed the existent studies on affective technologies and implemented the criteria into a system design, the Pictures' Call. A prototype of the system was pretested to illustrate how productive love technology could be based on established criteria.

Identification of a single-nucleotide insertion in the promoter region affecting the sodC promoter activity in Brucella neotomae.

Directory of Open Access Journals (Sweden)

Dina A Moustafa

Full Text Available Brucella neotomae is not known to be associated with clinical disease in any host species. Previous research suggested that B. neotomae might not express detectable levels of Cu/Zn superoxide dismutase (SOD, a periplasmic enzyme known to be involved in protecting Brucella from oxidative bactericidal effects of host phagocytes. This study was undertaken to investigate the genetic basis for the disparity in SOD expression in B. neotomae. Our Western blot and SOD enzyme assay analyses indicated that B. neotomae does express SOD, but at a substantially reduced level. Nucleotide sequence analysis of region upstream to the sodC gene identified a single-nucleotide insertion in the potential promoter region. The same single-nucleotide insertion was also detected in the sodC promoter of B. suis strain Thomsen, belonging to biovar 2 in which SOD expression was undetectable previously. Examination of the sodC promoter activities using translational fusion constructs with E. coli β-galactosidase demonstrated that the B. neotomae and B. suis biovar 2 promoters were very weak in driving gene expression. Site-directed mutation studies indicated that the insertion of A in the B. neotomae sodC promoter reduced the promoter activity. Increasing the level of SOD expression in B. neotomae through complementation with B. abortus sodC gene did not alter the bacterial survival in J774A.1 macrophage-like cells and in tissues of BALB/c and C57BL/6 mice. These results for the first time demonstrate the occurrence of a single-nucleotide polymorphism affecting promoter function and gene expression in Brucella.

Children affected by HIV/AIDS: SAFE, a model for promoting their security, health, and development.

Science.gov (United States)

Betancourt, Theresa S; Fawzi, Mary K S; Bruderlein, Claude; Desmond, Chris; Kim, Jim Y

2010-05-01

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.

Organizational identification and the communication of identity: effects of message characteristics on cognitive and affective identification.

Science.gov (United States)

Tanis, Martin; Beukeboom, Camiel J

2011-12-01

This paper reports an experimental study (N= 321) that tests how the cognitive and affective component of organizational identification (OI) can be affected by peripheral characteristics of organizational communication. Results show that adding cues in emails that signal organizational identity, such as the company logo, font, and colour of text, positively affect the cognitive component of OI, but not the affective component. In contrast, a personal focus in the message had a positive effect on the affective, but not on the cognitive component of OI. This study supports the idea that OI is a multi-faceted construct comprising a cognitive and affective component, and that these different components can be affected by different characteristics of organizational email messages. ©2011 The British Psychological Society.

To review characteristics and outcomes of patients who underwent primary pneumatic retinopexy (PR) for repair of rhegmatogenous retinal detachment in a multioffice retina practice and to determine what preoperative characteristics were associated with success or failure of PR. A retrospective medical record review was conducted of patients who underwent primary PR from September 2001 to March 2009. Patients with less than 6 months of follow-up were excluded. Data collected on each patient included age, sex, affected eye, preoperative visual acuity, lens status, presence of posterior vitreous detachment, presence of vitreous hemorrhage, macular status, presence of lattice degeneration, number and location of retinal breaks, clock hour extent of detachment, final visual acuity, final retinal status, number of procedures to reattach retina, and duration of follow-up. Two hundred thirteen patients were included. The mean age was 59.3 years and 53.5% were male. Mean follow-up was 24.6 months, and 64.8% of patients had a successful PR. Vitreous hemorrhage and retinal detachment greater than 4.5 clock hours were the 2 factors that significantly affected successful outcome (P = .04 and .01, respectively). The overall mean final visual acuity was 20/40, with a mean of 20/30 in the success group and a mean of 20/60 in the failure group (P treatment option for certain types of rhegmatogenous retinal detachment. In patients with vitreous hemorrhage and detachments greater than 4.5 clock hours, the success rate may be lower. Final visual acuity is better with successful reattachment with a single procedure.

Get a taste of your goals: promoting motive-goal congruence through affect-focus goal fantasy.

Job, Veronika; Brandstätter, Veronika

2009-10-01

Studies show that motive-goal congruence is an important predictor of well-being (Baumann, Kaschel, & Kuhl, 2005; Brunstein, Schultheiss, & Grässmann, 1998). However, little is known about the factors that promote congruence between implicit motives and goals. Relying on McClelland's (1985) concept of implicit motives and the theory of fantasy realization (Oettingen, 1999), we postulated that goal fantasies focusing on motive-specific affective incentives promote motive-congruent goal setting. This hypothesis was tested in 3 experimental studies. In Study 1 (n=46) and Study 2 (n=48), participants were asked to select goals in a hypothetical scenario. In Study 3 (n=179), they rated their commitment to personal goals for their actual life situation. The results of all 3 studies supported our hypothesis that participants who focus on motive-specific affective incentives in their goal fantasies set their goals in line with their corresponding implicit motive dispositions.

2014-10-01

Full Text Available Background: The Development of Groups and Leaders (UGL, provided by the Swedish National Defence College and mentored by UGL-trainers, is one of the most popular management programs among civilians in Sweden. However, there is a lack of scientific evidence regarding the training. We used the affective profile model (i.e., the combination of positive, PA, and negative affect, NA to mapp important markers of empowerment, self-awareness, adaptive coping skills, and maturity among the UGL-trainers. The aims were: (1 to compare profiles between UGL-trainers and managers/supervisors and (2 to investigate differences in personal characteristics.Method: UGL-trainers (N = 153 and the comparison group (104 Swedish Chiefs of Police completed an online survey on optimism, self-esteem, locus of control, and affect. The four profiles are: self-fulfilling (high PA, low NA, high affective (high PA, high NA, low affective (high PA, low NA, and self-destructive (low PA, high NA,Results: The self-fulfilling profile was more common among UGL-trainers (25.70% than among Chiefs of Police (19.20%. UGL-trainers, compared to Chiefs of Police, were more likely to express a self-fulling than a low affective profile (OR=2.22, p < .05 and a high affective than a low affective profile (OR=1.43, p <.001. UGL-trainers with a self-fulfilling profile, compared to those with a self-destructive profile, scored higher in optimism, higher in self-esteem, and lower in external locus of control. Conclusions: The probability of self-fulfilment rather than low affectivity was higher among UGL-trainers. Self-fulfilment was associated to markers of self-awareness and adaptive coping skills. However, the most common profile was the low affective, which is associated to low performance during stress, low degree of personal development, low degree of purpose in life, and low resilience. Hence, it might be important for UGL-trainers to have a continuos training in awareness after

2002-12-01

This study assessed characteristics of psychiatric patients for whom financial considerations affected the provision of "optimal" treatment. Psychiatrists reported that for 33.8 percent of 1,228 patients from a national sample, financial considerations such as managed care limitations, the patient's personal finances, and limitations inherent in the public care system adversely affected the provision of optimal treatment. Patients were more likely to have their treatment adversely affected by financial considerations if they were more severely ill, had more than one behavioral health disorder or a psychosocial problem, or were receiving treatment under managed care arrangements. Patients for whom financial considerations affect the provision of optimal treatment represent a population for whom access to treatment may be particularly important.

A study was carried out to assess the nature and extent of worksite health promotion programs in Fortune 500 companies. Growth and interest in worksite health promotion continues at a remarkable rate. Fortune 500 firms are a good barometer of the state of the art of programs in work settings because these companies have large numbers of employees, an interest in cost savings, and expertise to invest in innovative efforts. Data collection consisted of questionnaires sent to the medical officer or Chief Executive Officer of all companies appearing on the 1984 Fortune 500 list. The following issues were addressed: whether companies offered worksite programs; what health promotion activities were provided in their programs; whether organizations had plans to start up or expand programs; what organizational support existed for programs (i.e. who pays, on whose time employees participate, when activities are offered, and what types of personnel are hired to staff programs); and whether these companies applied needs assessments, evaluation and cost analysis in their programs. Differences in these characteristics were examined in relation to the organizational variables of size (number of employees), Fortune 500 rank and type of industry (low-technology versus high-technology). The response rate for the survey was 49.4% (n = 247). Results of the study indicate a high level of health promotion activity in Fortune 500 firms. Out of the total group of respondents, two-thirds (n = 164) report having worksite programs and two-thirds of organizations with programs have plans to expand their health promotion offerings. One-third of responding organizations without programs planned to initiate them. The health promotion activities provided are numerous and varied, and within units that have programs rates of employee eligibility are reported to be high. However, the participation rates reported are appreciably lower. It is of special interest that, in general, the higher ranked

Barrier islands are complex and dynamic systems that provide critical ecosystem services to coastal populations. Stability of these systems is threatened by rising sea level and the potential for coastal storms to increase in frequency and intensity. Recovery of dune-building grasses following storms is an important process that promotes topographic heterogeneity and long-term stability of barrier islands, yet factors that drive dune recovery are poorly understood. We examined vegetation recovery in overwash zones on two geomorphically distinct (undisturbed vs. frequently overwashed) barrier islands on the Virginia coast, USA. We hypothesized that vegetation recovery in overwash zones would be driven primarily by environmental characteristics, especially elevation and beach width. We sampled species composition and environmental characteristics along a continuum of disturbance from active overwash zones to relict overwash zones and in adjacent undisturbed environments. We compared species assemblages along the disturbance chronosequence and between islands and we analyzed species composition data and environmental measurements with Canonical Correspondence Analysis to link community composition with environmental characteristics. Recovering and geomorphically stable dunes were dominated by Ammophila breviligulata Fernaud (Poaceae) on both islands while active overwash zones were dominated by Spartina patens (Aiton) Muhl. (Poaceae) on the frequently disturbed island and bare sand on the less disturbed island. Species composition was associated with environmental characteristics only on the frequently disturbed island (p = 0.005) where A. breviligulata was associated with higher elevation and greater beach width. Spartina patens, the second most abundant species, was associated with larger sediment grain size and greater sediment size distribution. On the less frequently disturbed island, time since disturbance was the only factor that affected community

External built residential environment characteristics include aspects of building design such as types of walls, doors and windows, green spaces, density of houses per unit area, and waste disposal facilities. Neighborhoods that are characterized by poor quality external built environment can contribute to psychosocial stress and increase the likelihood of mental health disorders. This study investigated the relationship between characteristics of external built residential environment and mental health disorders in selected residences of Nakuru Municipality, Kenya. External built residential environment characteristics were investigated for 544 residents living in different residential areas that were categorized by their socioeconomic status. Medically validated interview schedules were used to determine mental health of residents in the respective neighborhoods. The relationship between characteristics of the external built residential environment and mental health of residents was determined by multivariable logistic regression analyses and chi-square tests. The results show that walling materials used on buildings, density of dwelling units, state of street lighting, types of doors, states of roofs, and states of windows are some built external residential environment characteristics that affect mental health of adult males and females. Urban residential areas that are characterized by poor quality external built environment substantially expose the population to daily stressors and inconveniences that increase the likelihood of developing mental health disorders.

Schools are important arenas for interventions among children as health promoting initiatives in childhood is expected to have substantial influence on health and well-being in adulthood. In countries with compulsory school attention, all children could potentially benefit from health promotion at the school level regardless of socioeconomic status or other background factors. The first aim was to elucidate time trends in the number and types of school health promoting activities by describing the number and type of health promoting activities in primary and secondary schools in Denmark. The second aim was to investigate which characteristics of schools and students that are associated with participation in many (≥3) versus few (0-2) health promoting activities during the preceding 2-3 years. We used cross-sectional data from the 2006- and 2010-survey of the Health Behaviour in School-aged Children study. The headmasters answered questions about the school's participation in health promoting activities and about school size, proportion of ethnic minorities, school facilities available for health promoting activities, competing problems and resources at the school and in the neighborhood. Students provided information about their health-related behavior and exposure to bullying which was aggregated to the school level. A total of 74 schools were available for analyses in 2006 and 69 in 2010. We used chi-square test, t-test, and binary logistic regression to analyze time trends and differences between schools engaging in many versus few health promoting activities. The percentage of schools participating in ≥3 health promoting activities was 63% in 2006 and 61% in 2010. Also the mean number of health promoting activities was similar (3.14 vs. 3.07). The activities most frequently targeted physical activity (73% and 85%) and bullying (78% and 67%). Schools' participation in anti-smoking activities was significantly higher in 2006 compared with 2010 (46% vs. 29

The purpose of this study was to provide a descriptive profile of food-related advertising, messaging, and signage in Vancouver schools and to examine differences in the prevalence and characteristics of promotions between elementary and secondary schools. All food-related promotions were photographed in 23 diverse Vancouver public schools between November 2012 and April 2013. Key attributes, including the location, size, and main purpose of each promotion, as well as the type of food and/or beverage advertised and compliance with provincial school nutrition guidelines, were coded. Descriptive statistics assessed the prevalence and characteristics of promotions. Cross-tabulations examined whether the promotional landscape differed between elementary and secondary schools. All secondary and 80% of elementary schools contained food or beverage promotions (median = 17, range = 0-57 promotions per school). Of the 493 promotions documented, approximately 25% depicted "choose least" or "not recommended" items, prohibited for sale by provincial school nutrition guidelines. Nearly 1/3 of promotions advertised commercial items (e.g., brand name beverages such as Pepsi), in violation of the Board of Education's advertising policies and only 13% conveyed nutrition education messages. Close to half of all promotions were created by students for class projects, many of which marketed minimally nutritious items. In Vancouver schools, food-related promotions are common and are more prevalent in secondary than elementary schools. Students are regularly exposed to messaging for nutritionally poor items that are not in compliance with provincial school nutrition guidelines and which violate school board advertising policies. Stronger oversight of food-related promotional materials is needed to ensure that schools provide health promoting food environments.

The effects of different temperature and time conditions during retorting of canned cat food on physicochemical characteristics and palatability were examined. For this purpose, lacquer cans containing an unprocessed loaf-type commercial cat food were heated in a pressurised retorting system at three specified temperature-time profiles (113°C/232 min, 120°C/103 min and 127°C/60 min) to equal a similar lethality ( F 0 value = 30). Physicochemical properties (viscosity, texture, particle size, pH) were determined, and a 10 d three-bowl palatability test was performed with ten European shorthair cats. Retorting at 113°C/232 min resulted in differences in all the physical parameters examined ( particle size). Significant pH differences were observed (6·53, 6·63 and 6·66 for T113/232, 120 and 127°C, respectively). Preference ratios were 0·38, 0·31 and 0·31 for T113/232, 120 and 127°C, respectively ( P  = 0·067). It can be concluded that different retorting temperature-time profiles with equal F 0 value significantly affect physical characteristics and tended to affect palatability of moist cat food.

MDM2 promoter SNP344T>A (rs1196333 status does not affect cancer risk.

Directory of Open Access Journals (Sweden)

Stian Knappskog

Full Text Available The MDM2 proto-oncogene plays a key role in central cellular processes like growth control and apoptosis, and the gene locus is frequently amplified in sarcomas. Two polymorphisms located in the MDM2 promoter P2 have been shown to affect cancer risk. One of these polymorphisms (SNP309T>G; rs2279744 facilitates Sp1 transcription factor binding to the promoter and is associated with increased cancer risk. In contrast, SNP285G>C (rs117039649, located 24 bp upstream of rs2279744, and in complete linkage disequilibrium with the SNP309G allele, reduces Sp1 recruitment and lowers cancer risk. Thus, fine tuning of MDM2 expression has proven to be of significant importance with respect to tumorigenesis. We assessed the potential functional effects of a third MDM2 promoter P2 polymorphism (SNP344T>A; rs1196333 located on the SNP309T allele. While in silico analyses indicated SNP344A to modulate TFAP2A, SPIB and AP1 transcription factor binding, we found no effect of SNP344 status on MDM2 expression levels. Assessing the frequency of SNP344A in healthy Caucasians (n = 2,954 and patients suffering from ovarian (n = 1,927, breast (n = 1,271, endometrial (n = 895 or prostatic cancer (n = 641, we detected no significant difference in the distribution of this polymorphism between any of these cancer forms and healthy controls (6.1% in healthy controls, and 4.9%, 5.0%, 5.4% and 7.2% in the cancer groups, respectively. In conclusion, our findings provide no evidence indicating that SNP344A may affect MDM2 transcription or cancer risk.

Despite a large body of evidence showing that physical activity (PA) is beneficial to patients with cancer, healthcare professionals (HCPs) are promoting it too scarcely. Factors that hinder HCPs from promoting PA have remained understudied so far. Using a qualitative approach, this study aimed at a comprehensive description of influencing factors for HCPs' PA promotion behaviour and at identifying the reasons and mechanisms behind them. Semi-structured interviews with 30 HCPs were undertaken with a focus on concerns, patient characteristics and structural factors. Answers were analysed using thematic analysis. Results revealed that HCPs had concerns regarding a physical overexertion and psychological stress for patients with cancer. A patient's physical condition and the assumed interest in PA, often derived from former PA, turned out to be the most crucial patient characteristics influencing if PA is addressed. Structural factors relevant for PA promotion pertained to in-house structures, HCPs' workload, timing and coordination, information material for HCPs and patients and availability of exercise programs. In conclusion, this study revealed undetected concerns of HCPs and underlined the relevance of patient characteristics and structural conditions for HCPs' PA promotion towards patients with cancer. A broader perspective is needed to assess these factors in their influence on HCPs' PA promotion. © 2018 John Wiley & Sons Ltd.

Seismic data two-step recovery approach combining sparsity-promoting and hyperbolic Radon transform methods

Wang, Hanchuang; Chen, Shengchang; Ren, Haoran; Liang, Donghui; Zhou, Huamin; She, Deping

2015-01-01

In current research of seismic data recovery problems, the sparsity-promoting method usually produces an insufficient recovery result at the locations of null traces. The HRT (hyperbolic Radon transform) method can be applied to problems of seismic data recovery with approximately hyperbolic events. Influenced by deviations of hyperbolic characteristics between real and ideal travel-time curves, some spurious events are usually introduced and the recovery effect of intermediate and far-offset traces is worse than that of near-offset traces. Sparsity-promoting recovery is primarily dependent on the sparsity of seismic data in the sparse transform domain (i.e. on the local waveform characteristics), whereas HRT recovery is severely affected by the global characteristics of the seismic events. Inspired by the above conclusion, a two-step recovery approach combining sparsity-promoting and time-invariant HRT methods is proposed, which is based on both local and global characteristics of the seismic data. Two implementation strategies are presented in detail, and the selection criteria of the relevant strategies is also discussed. Numerical examples of synthetic and real data verify that the new approach can achieve a better recovery effect by simultaneously overcoming the shortcomings of sparsity-promoting recovery and HRT recovery.

Full Text Available An experiment was conducted to evaluate the effect of using graded levels of roasted sesame hulls (RSH on growth performance and meat quality characteristics in broiler chickens. A total of 360 day-old Lohmann chicks were randomly allocated into 24 floor pens and raised over 42 days. One of four dietary treatments was assigned to each group of six pens in a completely randomized fashion. The chicks in the control group were fed a corn-soybean based diet (RSH-0, while the chicks in treatments two, three, and four were fed graded levels of RSH at 4% (RSH-4, 8% (RSH-8, and 12% (RSH-12, respectively. Diets were formulated to meet broiler chicks’ requirements according to the National Research Council for both starter and finisher rations. The results showed that RSH inclusion increased (P<0.05 feed intake and final body weight without adversely affecting the feed conversion ratio. Broiler chicks fed RSH-12 had heavier (P<0.05 breast and leg cuts compared to the control-fed group with no change to their chemical composition. Water holding capacity (WHC, cooking loss (CL, and shear force (SF reported similar results in all dietary groups. The chemical composition of both thigh and breast cuts was not affected by the RSH. After one day of thawing, colour coordinates of breast cuts behaved similarly in all dietary groups. The results of this study suggest that the addition of RSH to broiler diets up to 12% improves their growth performance; nevertheless, carcass characteristics and meat quality showed no alterations compared to the control-fed group.

The purpose of this study was to investigate the effects of personal characteristics and theory of planned behavior (TPB) constructs on the intention to participate in a restaurant health promotion program. In total, 830 adults residing in Seoul were sampled by a multi-stage cluster and random sampling design. Data were collected from a structured self-administered questionnaire, which covered variables concerning demographics, health status and TPB constructs including attitude, subjective norm and perceived behavioral control. A path analysis combining personal characteristics and TPB constructs was used to investigate determinants of the customers' intention. Positive and negative attitudes, subjective norms and perceived behavioral control directly affected the intention to participate. Demographics and health status both directly and indirectly affected the intention to participate. This study identifies personal characteristics and TPB constructs that are important to planning and implementing a restaurant health promotion program.

Story Immersion of Videogames for Youth Health Promotion: A Review of Literature.

Lu, Amy Shirong; Baranowski, Tom; Thompson, Debbe; Buday, Richard

2012-06-01

This article reviews research in the fields of psychology, literature, communication, human-computer interaction, public health, and consumer behavior on narrative and its potential relationships with videogames and story immersion. It also reviews a narrative's role in complementing behavioral change theories and the potential of story immersion for health promotion through videogames. Videogames have potential for health promotion and may be especially promising when attempting to reach youth. An understudied characteristic of videogames is that many contain a narrative, or story. Story immersion (transportation) is a mechanism through which a narrative influences players' cognition, affect, and, potentially, health behavior. Immersion promotes the suspension of disbelief and the reduction of counterarguments, enables the story experience as a personal experience, and creates the player's deep affection for narrative protagonists. Story immersion complements behavioral change theories, including the Theory of Planned Behavior, Social Cognitive Theory, and Self-Determination Theory. Systematic investigations are needed to realize the powerful potential of interactive narratives within theory-driven research.

It is important to collect data about human behavior in work situation and data about work performance. On the basis of these data we can analyse human errors. Human reliability analysis gives us the input data to improve human behavior at a work place. We have tried to define those human characteristics that have impact on safe work and operation. Estimation of a work place was used for determination of important human characteristics. Performance estimations were used to define the availability of workers at a work place. To our experience it is very important to pay attention to R.A. and R.C. also in the area of human factor. Data for quality assurance in the area of human factor should be collected from selection procedure (the level of cognitive and conative abilities, the level of physical characteristics, the level of education and other personal data). Data for quality control should be collected from the periodical examinations of annual checking and evaluation of human working capacity as well as from training. For quality control of every day human performance data of staff estimation of their daily working performance and well-being should also be collected. With all these data more effective analyses of all events in nuclear power plants could be provided. Quality assurance and quality control in the area of human factor could help us to keep the optimum performance level of the plant staff and to avoid human errors. (author). 3 refs, 3 figs

Pakistan's water crisis, especially serious water shortages have had a great impact on the health of the general population. Today majority of Pakistanis have no access to improved water sources which force people to consume polluted drinking water that results in the shape of waterborne diseases. In addition to this, household characteristics, includes mother's education and family income, also have an impact on drinking water quality and ultimately on human health. This study was conducted in three districts of Province Punjab both in urban and rural areas. The sample size of this study was 600 females of age group 20-60 years. From the data, it was concluded that mother's education and family income were affecting drinking water quality and human health. As the mother's years of education increased, the health issues decreased. Similarly, as the level of income increased, people suffered from water related diseases decreased. (author)

Affective temperaments may carry distinct evolutionary advantages both on the individual or a group level, so we can expect that in different cultural and national samples the frequency of dominant affective temperaments will show characteristic differences. The aim of the present study was to investigate the characteristics of distribution of dominant affective temperaments in different national studies of general non-clinical population. In our study we included six studies published in different countries around the world (Argentina, Germany, Hungary, Korea, Portugal, and Lebanon) which investigated a large sample of non-clinical population using TEMPS-A, and reported frequencies for dominant affective temperaments. The frequencies of dominant affective temperaments were compared using chi square tests. We found a significant difference in the frequency of affective temperaments among the different national studies in case of the cyclothymic, hyperthymic and irritable temperaments. We found important parallels between the frequency of affective temperaments and cultural dimensions described by Hofstede (Hofstede and Hofstede, 2005). The characteristics encompassed by the depressive temperament show considerable similarities with Hofstede's individualism-collectivism dimension, while those of the hyperthymic temperament seem to be similar to uncertainty avoidance, and the irritable temperament shows similarities with Hofstede's power distance. Furthermore, the relative frequency of these dominant temperaments in case of the different national samples paralleled the relative scores of these countries on the corresponding cultural scales. Our results indicate an important relationship between affective temperaments and cultural dimensions, which suggests that these phenomena may be the manifestations of the same genetically determined predispositions in different forms. We included a study by Erfurth et al. (2005), in which affective temperaments were evaluated

In Japan, consumption of Natto, a fermented bean dish, is recommended because of its high quality protein, digestibility in the gut and its preventive effect on blood clot formation due to high vitamin K content. However, consumption of Natto in Kansai and the Chugoku area (the western part of Honshu) is less than that in the other areas of Japan probably because of a "food related cultural inhibition". In this study, we determined which characteristic of Natto (appearance, odor or taste) most affect subjects' perception of sensory attributes by observation of brain hemodynamics in relation to subjects' preference for Natto. In this experiment, we defined each subject's changes in brain hemodynamics as (+) or (-) corresponding to an increase or a decrease in total hemoglobin concentration after stimuli compared to that before stimuli. As a result, there was no relation between preference for Natto and change in brain hemodynamics by the stimuli of "looking at" or "smelling", while there was a significant relationship between preference and stimulus of "ingestion"; (+) : (-) = 21:15 in the subjects of the "favorite" group and (+):(-) = 30:7 in the subjects of the "non-favorite" group (P = 0.034). This result indicated that characteristic "taste" of Natto most affects preference for Natto.

Research focusing on the relationship between organizational justice and health suggests that perceptions of fairness can make significant contributions to employee wellbeing. However, studies examining the justice-health relationship are only just emerging and there are several areas where further research is required, in particular, the uniqueness of the contributions made by justice and the extent to which the health effects can be explained by linear, non-linear and/or interaction models. The primary aim of the current study was to determine the main, curvilinear and interaction effects of work characteristics and organizational justice perceptions on employee wellbeing (as measured by psychological health and job satisfaction). Work characteristics were measured using the demand-control-support (DCS) model (Karasek and Theorell, 1990) and Colquitt's (2001) four justice dimensions (distributive, procedural, interpersonal and informational) assessed organizational justice (Colquitt, 2001). Hierarchical regression analyses found that in relation to psychological health, perceptions of justice added little to the explanatory power of the DCS model. In contrast, organizational justice did account for unique variance in job satisfaction, the second measure of employee wellbeing. The results supported linear relationships between the psychosocial working conditions and the outcome measures. A significant two-way interaction effect (control x support at work) was found for the psychological health outcome and the procedural justice by distributive justice interaction was significant for the job satisfaction outcome. Notably, the findings indicate that in addition to traditional job stressors, health promotion strategies should also address organizational justice.

Foods with added phytosterols/phytostanols (PS) are recommended to lower LDL cholesterol (LDL-c) concentrations. Manufacturers have incorporated PS into a variety of common foods. Understanding the cholesterol-lowering impact of the food matrix and the PS characteristics would maximize their success and increase the benefit to consumers. This review systematically examines whether the PS characteristics and the fatty acid composition of foods with added PS affects serum LDL-c. A total of 33 studies published between the years 1998 and 2011 inclusive of 66 individual primary variables (strata) were evaluated. The functional food matrices included margarine, mayonnaise, yogurt, milk, cheese, meat, grain, juice, and chocolate. Consistently, ≥10% reductions in LDL-c were reported when the characteristics of the food matrix included poly- and monounsaturated fatty acids known to lower LDL-c. Also, >10% mean reductions in LDL-c were reported when β-sitostanol and campestanol as well as stanol esters were used. These characteristics allow both low-fat and high-fat foods to successfully incorporate PS and significantly lower LDL-c.

Full Text Available Purpose statement – This paper’s purpose is to contribute to the development of a specific know-how through the establishment of a theoretical framework of reference. This can facilitate the research steps which follow the identification; analysis; and interpretation of a new marketing instrument – promotional journalism. The objectives, of this study, relate not only to the establishment of theoretical but, also, to the practical characteristics, of promotional journalism. These are based on a comparative analysis with other related concepts and, also, on a qualitative analysis of the contents of the specific materials. Design – The research problem imposes a methodological interdisciplinary approach; this enables the identification; systematization; analysis; and theoretical interpretation of the fundamental concepts, theories and ideas, from the specialized literature, to be orientated towards studies and articles from separate fields. From the perspective of the research objectives and this interdisciplinary study of specilized literature, there was added a qualitative analysis of the content of the materials specific to promotional journalism found between 2002 and 2006, in the fashion magazine, Elle Romania. Overview - The specialized literature presented key-concepts; different terminologies; and meanings apparently for the same studied “reality“. This made the achievement of the process of conceptual delimitations even more difficult to the extent that promotional journalism was situated at the intersection of various sciences and the acknowledgment, of its related terms, were either similar or stated vaguely. Originality – This paper’s originality stems from the interdisciplinary perspective to the approach to the problematical aspect and the analysis and interpretitive complexity of the research results. These might prove useful both to the accomplishment of the studies in the field and for the practitioners and

Trichoderma species are soil-borne filamentous fungi widely utilized for their many plant health benefits, such as conferring improved growth, disease resistance and abiotic stress tolerance to their hosts. Many Trichoderma species are able to produce the auxin phytohormone indole-3-acetic acid (IAA), and its production has been suggested to promote root growth. Here we show that the production of IAA is strain dependent and diverse external stimuli are associated with its production. In in vitro assays, Arabidopsis primary root length was negatively affected by the interaction with some Trichoderma strains. In soil experiments, a continuum effect on plant growth was shown and this was also strain dependent. In plate assays, some strains of Trichoderma spp. inhibited the expression of the auxin reporter gene DR5 in Arabidopsis primary roots but not secondary roots. When Trichoderma spp. and A. thaliana were physically separated, enhancement of both shoot and root biomass, increased root production and chlorophyll content were observed, which strongly suggested that volatile production by the fungus influenced the parameters analyzed. Trichoderma strains T. virens Gv29.8, T. atroviride IMI206040, T. sp. “atroviride B” LU132, and T. asperellum LU1370 were demonstrated to promote plant growth through volatile production. However, contrasting differences were observed with LU1370 which had a negative effect on plant growth in soil but a positive effect in plate assays. Altogether our results suggest that the mechanisms and molecules involved in plant growth promotion by Trichoderma spp. are multivariable and are affected by the environmental conditions.

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.

Women are more affected than men by many chronic pain conditions, suggesting the effect of sex-related mechanisms in their occurrence. The role of gonadal hormones has been studied but with contrasting results depending on the pain syndrome, reproductive status, and hormone considered. The aim of the present study was to evaluate the pain changes related to the menopausal transition period. In this observational study, postmenopausal women were asked to evaluate the presence of pain in their life during the premenopausal and postmenopausal periods and its modification with menopause. One hundred one women were enrolled and completed questionnaires on their sociodemographic status, pain characteristics, and evolution. The most common pain syndromes were headache (38%), osteoarticular pain (31%), and cervical/lumbar pain (21%). Pain was present before menopause in 66 women, ceased with menopause in 17, and started after menopause in 18. Data were used for cluster analysis, which allowed the division of participants into four groups. In the first, all women experienced headaches that disappeared or improved with menopause. The second group included osteoarticular pain; the pain improved in half of these women and remained stable in the other half. The third group had cervical/lumbar pain, which disappeared or improved with menopause in all. The fourth group presented different kinds of moderate pain, which worsened in all. The present study provides preliminary data suggesting that menopause can affect pain depending on the painful condition experienced by the woman. This underlines the different interactions of menopause-related events with body structures involved in pain.

This study assessed whether participant baseline characteristics modified the effects of a skill-based intervention promoting condom use. The randomized, controlled trial enrolled 427 women from a sexually transmitted disease clinic in Birmingham, Alabama. The main outcome measures: consistent (100%) and problem-free (correct, no breakage or slippage) condom use were verified by sexual diary self-report and contraceptive product counts. The enhanced intervention group had a 60% higher consistent condom use rate compared to the basic group (risk ratio [RR], 1.6; 95% confidence interval [CI], 1.4-1.8). There was no statistically significant difference between groups in relationship to problem-free, consistent use (RR, 1.0; 95% CI, 0.9-1.1). A binomial regression analysis identified the following factors as significant modifiers of intervention effectiveness on consistent condom use: intention to use condoms next time, early-age sexual debut, marital status combined with place of intercourse, and substance use before sex. The results suggest that participant baseline characteristics can be modifiers of intervention effectiveness.

Researchers assessed the possible moderating effects of school organizational characteristics (school climate, school health, and job satisfaction) on outcomes of a teacher health behavior change program. Thirty-two public schools were matched and randomly assigned either to treatment or control conditions. Organizational, dietary, and physiologic data were collected from third to fifth grade teachers over three years. Treatment schools received a teacher wellness program for two years. Psychometrics of most organizational scales achieved acceptable levels of reliability. Mixed model analyses were conducted to test for moderating effects. Treatment schools with high organizational climate and health scores reported higher fruit and juice and vegetable consumption at Year 2 compared with intervention schools with low scores. Treatment schools with high job satisfaction scores reported higher fruit and juice and lower-fat food consumption at Year 3 compared with intervention schools with low scores. These measures may be used as a tool to assess the environment in which school health promotion programs are presented. Future interventions may need to be tailored to the organizational characteristics of schools.

Why do people give to strangers? We propose that people trust and give more to those whose emotional expressions match how they ideally want to feel ("ideal affect match"). European Americans and Koreans played multiple trials of the Dictator Game with recipients who varied in emotional expression (excited, calm), race (White, Asian) and sex (male, female). Consistent with their culture's valued affect, European Americans trusted and gave more to excited than calm recipients, whereas Koreans trusted and gave more to calm than excited recipients. These findings held regardless of recipient race and sex. We then used fMRI to probe potential affective and mentalizing mechanisms. Increased activity in the nucleus accumbens (associated with reward anticipation) predicted giving, as did decreased activity in the right temporo-parietal junction (rTPJ; associated with reduced belief prediction error). Ideal affect match decreased rTPJ activity, suggesting that people may trust and give more to strangers whom they perceive to share their affective values. © The Author (2017).

How are streamflow responses to the El Nino Southern Oscillation affected by watershed characteristics?

Rice, Joshua S.; Emanuel, Ryan E.

2017-05-01

Understanding the factors that influence how global climate phenomena, such as the El-Nino Southern Oscillation (ENSO), affect streamflow behavior is an important area of research in the hydrologic sciences. While large-scale patterns in ENSO-streamflow relationships have been thoroughly studied, and are relatively well-understood, information is scarce concerning factors that affect variation in ENSO responses from one watershed to another. To this end, we examined relationships between variability in ENSO activity and streamflow for 2731 watersheds across the conterminous U.S. from 1970 to 2014 using a novel approach to account for the intermediary role of precipitation. We applied an ensemble of regression techniques to describe relationships between variability in ENSO activity and streamflow as a function of watershed characteristics including: hydroclimate, topography, geomorphology, geographic location, land cover, soil characteristics, bedrock geology, and anthropogenic influences. We found that variability in watershed scale ENSO-streamflow relationships was strongly related to factors including: precipitation timing and phase, forest cover, and interactions between watershed topography and geomorphology. These, and other influential factors, share in common the ability to affect the partitioning and movement of water within watersheds. Our results demonstrate that the conceptualization of watersheds as signal filters for hydroclimate inputs, commonly applied to short-term rainfall-runoff responses, also applies to long-term hydrologic responses to sources of recurrent climate variability. These results also show that watershed processes, which are typically studied at relatively fine spatial scales, are also critical for understanding continental scale hydrologic responses to global climate.

Brasel, S Adam

2010-09-01

Adding promotions to online services is increasingly commonplace, yet consumers may have difficulty determining whether service-embedded promotions are goal-relevant, due to the linear and transactional nature of online services. This contextual effect of goal-relevance ambiguity on promotions is explored across three studies. An exploratory study utilizing actual service websites and a broad range of consumers as participants showed promotional elements in online services generated considerable confusion, and instructions labeling promotions as optional did little to relieve goal-relevance ambiguity. A second study using student participants inserted promotions into an online airline ticket service, a shopping site, a local news blog, and a news headline aggregator, to explore how linear and transactional sites such as online services compared to more exploratory or informational online environments. Results showed that service-embedded promotions enjoyed initial compliance far beyond promotions in traditional websites but also generated increased confusion, frustration, and anger. A third study utilizing student participants explored how varying levels of online service experience created differing responses to promotions in services; novices were less able to judge promotional goal-relevance and experienced more confusion, whereas experienced searchers were more likely to respond with frustration and anger. Many participants complied with promotional offers at the time of the service transaction, but stated intentions to use the promotion postservice were very low. The overall results spotlight goal-relevance ambiguity as an important driver of consumer response to online promotions, and highlight the role website context can play in the processing of online promotional elements.

To determine the prevalence of workplace violence and explore the role of hospital organizational characteristics and health promotion efforts in reducing hospital violence among nurses in Taiwan. Cross-sectional survey. One hundred hospitals across Taiwan. The final sample in our study comprised responses from 26,979 nurses. The data were obtained from a nationwide hospital survey, Physical and Mental Health and Safety Needs in Full-Time Health Care Staff, which was developed and conducted by the Bureau of Health Promotion, Taiwan, in 2011. The main dependent variable was whether nurses had experienced violence within the past year. Physical violence, threatened or intimidated personal safety, verbal violence or sexual harassment were all included. Of the 26,979 nurses, 13,392 nurses (49.6%) had experienced at least one episode of any type of violence in the past year; 5150 nurses (19.1%) had been exposed to physical violence, and 12,491 nurses (46.3%) had been exposed to non-physical violence. The prevalence of having experienced any violence varied widely and ranged from the highest (55.5%) in an emergency room or intensive care unit to the lowest (28.3%) among those aged 55-65 years. After adjusting for other characteristics, younger nurses were significantly more likely to be exposed to any violent threat. Nurses working in public hospitals had a significantly higher risk of workplace violence than those working in private hospitals. Significant variations were also observed among work units. Although nurses working in a certified health promoting hospital (HPH) did not have a lower risk of workplace violence, those working in an outstanding HPH had a significantly lower risk of workplace violence. A similar pattern was observed for non-physical violence. Workplace violence is a major challenge to workplace safety for nurses in hospitals. This large scale nurse survey identified individual, work and hospital characteristics associated with workplace violence

Full Text Available The first purpose of the present study was to investigate the role of individual characteristics, i.e., positive and negative affectivity, in explaining the different perception of job control and job demands in a particularly demanding environment such as the healthcare setting. In addition, we aimed to explore the mediational role of work engagement and workaholism using the Job Demands-Resources Model as a theoretical framework. Data were collected using a sample of 269 Italian head physicians working in nine general hospitals. To test our hypotheses, the collected data were analyzed with structural equation modeling. Moreover, Sobel Test and bootstrapping were employed to assess the mediating hypotheses. Our results indicated that positive affectivity is related to work engagement, which, in its turn, showed a positive association with job control. In addition, workaholism mediated the relationship between negative affectivity and job demands. All in all, this study represents a first attempt to explore the role of trait affectivity as a dispositional characteristic able to foster the level of work engagement and workaholism exhibited by employees and, in turn, to increase the perceived levels of job control and job demands.

The ability of As-resistant endophytic bacteria in As transformation and plant growth promotion was determined. The endophytes were isolated from As-hyperaccumulator Pteris vittata (PV) after growing for 60 d in a soil containing 200 mg kg(-1) arsenate (AsV). They were isolated in presence of 10 mM AsV from PV roots, stems, and leaflets, representing 4 phyla and 17 genera. All endophytes showed at least one plant growth promoting characteristics including IAA synthesis, siderophore production and P solubilization. The root endophytes had higher P solubilization ability than the leaflet (60.0 vs. 18.3 mg L(-1)). In presence of 10 mM AsV, 6 endophytes had greater growth than the control, suggesting As-stimulated growth. Furthermore, root endophytes were more resistant to AsV while the leaflet endophytes were more tolerant to arsenite (AsIII), which corresponded to the dominant As species in PV tissues. Bacterial As resistance was positively correlated to their ability in AsV reduction but not AsIII oxidation. The roles of those endophytes in promoting plant growth and As resistance in P. vittata warrant further investigation. Published by Elsevier Ltd.

Foods with added phytosterols/phytostanols (PS) are recommended to lower LDL cholesterol (LDL-c) concentrations. Manufacturers have incorporated PS into a variety of common foods. Understanding the cholesterol-lowering impact of the food matrix and the PS characteristics would maximize their success and increase the benefit to consumers. This review systematically examines whether the PS characteristics and the fatty acid composition of foods with added PS affects serum LDL-c. A total of 33 studies published between the years 1998 and 2011 inclusive of 66 individual primary variables (strata) were evaluated. The functional food matrices included margarine, mayonnaise, yogurt, milk, cheese, meat, grain, juice, and chocolate. Consistently, ≥10% reductions in LDL-c were reported when the characteristics of the food matrix included poly- and monounsaturated fatty acids known to lower LDL-c. Also, >10% mean reductions in LDL-c were reported when β-sitostanol and campestanol as well as stanol esters were used. These characteristics allow both low-fat and high-fat foods to successfully incorporate PS and significantly lower LDL-c. PMID:24228192

2015-09-01

Full Text Available The aim of the study was to verify the hypothesis that positive affective tone of narratives is connected to the experience of posttraumatic growth among transplant patients. Kidney transplant patients (N = 51 and liver transplant patients (N = 48 participated in the study. In the first stage, about 10 weeks after transplant, the participants told two stories about important, freely chosen events from their lives. During the second meeting 10-12 months later we measured posttraumatic growth. Results indicated that the affective tone of narratives about past events was associated with the level of post-traumatic growth measured 10-12 months later. This proves that the affective tone of narratives about life, understood as a relatively constant individual characteristic, promote posttraumatic growth.

Background : One method for promoting drugs in Japan has been utilizing wholesalers for promotion; however, the effectiveness of the sales promotion has been brought into question. Methods : A total of 74,552 responses were collected from an internet survey of 511 prescribing doctors in hospitals with less than 19 beds, which recalled the visits by wholesalers' sales representatives (MS) in 2014. Each assessed the degree to which MS and/or sales representatives from a pharmaceutical company (MR) influenced a decision to prescribe each drug. The responses were analysed using the chi-square test and Goodman-Kruskal's gamma to evaluate the association between MS calls and doctors' prescription orders. Results : Results showed a significant effect of the MS calls on doctors' behaviours in terms of new drug prescriptions and subsequent behaviours. The results by therapeutic category showed a similar strong influence of the joint calls on new prescriptions on some therapeutic classes. The MS calls significantly influenced doctors to maintain and increase the prescription volume (p sales promotion on the part of MSs and MRs adds value to the prescription decisions. Moreover, results suggest that MSs enhance prescription outcomes in competitive therapeutic categories.

Worldwide, over one billion children and adolescents live in war-affected settings. At present, only limited research has investigated linkages between disrupted social ecology and adverse mental health outcomes among war-affected youth. In this study, we examine three community-level characteristics - social disorder and collective efficacy within the community, as reported by caregivers, and perceived stigma as reported by youth - in relation to externalizing behaviors and internalizing symptoms among male and female former child soldiers in postconflict Sierra Leone. A total of 243 former child soldiers (30% female, mean age at baseline: 16.6 years) and their primary caregivers participated in interviews in 2004 and 2008, as part of a larger prospective cohort study of war-affected youth in Sierra Leone. Two-point growth models were estimated to examine the relationship between community-level characteristics and externalizing and internalizing outcomes across the time points. Both social disorder within the community, reported by caregivers, and perceived stigma, reported by youth, positively covaried with youths' externalizing and internalizing scores - indicating that higher levels of each at baseline and follow-up were associated with higher levels of mental health problems at both time points (p mental health outcomes was nonsignificant (p > .05). This study offers a rare glimpse into the role that the postconflict social context plays in shaping the mental health among former child soldiers. Results indicate that both social disorder and perceived stigma within the community demonstrate an important relationship to externalizing and internalizing problems among adolescent ex-combatants. Moreover, these relationships persisted over a 4-year period of follow-up. These results underscore the importance of the postconflict social environment and the need to develop postconflict interventions that address community-level processes in addition to the needs

Decision aids (DAs) are non-directive communication tools that help patients make value-consistent health-care decisions. However, most DAs have been developed without an explicit theoretical framework, resulting in a lack of understanding of how DAs achieve outcomes. To investigate the effect of promoting affective vs. deliberative processing on DA effectiveness based on dual-process theory. One hundred and forty-eight female university students participated in a randomized controlled experiment with three conditions: emotion-focused, information-focused and control. Preference-value consistency, knowledge, decisional conflict and satisfaction were compared across the conditions using planned contrast analyses. The intervention comprised two different DAs and instructional manipulations. The emotion-focused condition received a modified DA with affective content and instructions to induce an affective reaction. The information-focused and control conditions received the same DA without the affective content. The information-focused condition received additional instructions to induce deliberative processing. Controlling for the experiment-wise error rate at P processing may hinder value-consistent decision making, while deliberative processing may enhance decisional satisfaction. This investigation of the effect of affective and deliberative processes in DA-supported decision making has implications for the design and use of DAs. DA effectiveness may be enhanced by incorporating a simple instruction to focus on the details of the information. © 2014 John Wiley & Sons Ltd.

Ras proteins function as molecular switches in signal transduction pathways, and, here, we examined the effects of the K-ras4A and 4B splice variants on cell function by comparing wild-type embryonic stem (ES) cells with K-ras tmΔ4A/tmΔ4A (exon 4A knock-out) ES cells which express K-ras4B only and K-ras -/- (exons 1-3 knock-out) ES cells which express neither splice variant, and intestinal epithelium from wild-type and K-ras tmΔ4A/tmΔ4A mice. RT-qPCR analysis found that K-ras4B expression was reduced in K-ras tmΔ4A/tmΔ4A ES cells but unaffected in small intestine. K-Ras deficiency did not affect ES cell growth, and K-Ras4A deficiency did not affect intestinal epithelial proliferation. K-ras tmΔ4A/tmΔ4A and K-ras -/- ES cells showed a reduced capacity for differentiation following LIF withdrawal, and K-ras -/- cells were least differentiated. K-Ras4A deficiency inhibited etoposide-induced apoptosis in ES cells and intestinal epithelial cells. However, K-ras tmΔ4A/tmΔ4A ES cells were more resistant to etoposide-induced apoptosis than K-ras -/- cells. The results indicate that (1) K-Ras4A promotes apoptosis while K-Ras4B inhibits it, and (2) K-Ras4B, and possibly K-Ras4A, promotes differentiation. The findings raise the possibility that alteration of the K-Ras4A/4B isoform ratio modulates tumorigenesis by differentially affecting stem cell survival and/or differentiation. However, K-Ras4A deficiency did not affect life expectancy or spontaneous overall tumor incidence in aging mice

Van Den Berg, Agnes E; Custers, Mariëtte H G

2011-01-01

Stress-relieving effects of gardening were hypothesized and tested in a field experiment. Thirty allotment gardeners performed a stressful Stroop task and were then randomly assigned to 30 minutes of outdoor gardening or indoor reading on their own allotment plot. Salivary cortisol levels and self-reported mood were repeatedly measured. Gardening and reading each led to decreases in cortisol during the recovery period, but decreases were significantly stronger in the gardening group. Positive mood was fully restored after gardening, but further deteriorated during reading. These findings provide the first experimental evidence that gardening can promote relief from acute stress.

Urban sprawl and you: how sprawl adversely affects worker health.

Pohanka, Mary; Fitzgerald, Sheila

2004-06-01

Urban sprawl, once thought of as just an environmental issue, is currently gaining momentum as an emerging public health issue worthy of research and political attention. Characteristics seen in sprawling communities include increasing traffic volumes; inadequate public transportation; pedestrian unfriendly streets; and the division of businesses, shops, and homes. These characteristics can affect health in many ways. Greater air pollution contributes to higher asthma and other lung disorder rates. An increased dependence on the automobile encourages a more sedentary lifestyle and can potentially contribute to obesity. The increased danger and stress of long commutes can lead to more accidents, anxiety, and social isolation. Occupational health nurses can become involved by promoting physical activity in the workplace, creating programs for injury prevention and stress management, becoming involved in political smart growth measures, and educating and encouraging colleagues to become active in addressing this issue.

Full Text Available Dementia is classified as a mental disorder of a neurodegenerative nature that affects the Central Nervous System. Alzheimer’s disease is the most prevalent form of dementia that affects elderly people and it is defined as a progressive and persistent loss of multiple areas of intellectual functions. It gradually promotes deterioration in memory, learning, orientation, emotional stability and ability to communicate. Moreover, abstract thinking (paranoia and hallucinations and the decline of personal care such as bathing and performing oral hygiene are common, interfering in the individual’s social and daily life. According to its development, Alzheimer’s disease is divided into three distinct stages: initial, intermediate and terminal stage. The aim of this study was to approach the characteristics and suggest guidelines for dental attendance in the representative stages in the development of this dementia condition. The dentist should be aware of the different stages of this disease and its characteristics to provide patients with individual oral health attention. The participation of caregivers, family, and the health team is fundamental and it is also necessary to maintain oral health of these elderly patients.

Paddy rice may contribute considerably to the human intake of As. The knowledge of soil characteristics affecting the As content of the rice plant enables the development of agricultural measures for controlling As uptake. During field surveys in 2004 and 2006, plant samples from 68 fields (Italy, Po-area) revealed markedly differing As concentration in polished rice. The soil factors total As (aquaregia) , pH, grain size fractions, total C, plant available P (CAL) , poorly crystalline Fe (oxal.) and plant available Si (Na-acetate) content that potentially affect As content of rice were determined. A multiple linear regression analysis showed a significant positive influence of the total As (aquaregia) and plant available P (CAL) content and a negative influence of the poorly crystalline Fe (oxal.) content of the soil on the As content in polished rice and rice straw. Si concentration in rice straw varied widely and was negatively related to As content in straw and polished rice. - Field selection for total As, poorly crystalline Fe and plant available P in soil might contribute to control As content of paddy rice.

Pol II promoter prediction using characteristic 4-mer motifs: a machine learning approach

2008-10-01

Full Text Available Abstract Background Eukaryotic promoter prediction using computational analysis techniques is one of the most difficult jobs in computational genomics that is essential for constructing and understanding genetic regulatory networks. The increased availability of sequence data for various eukaryotic organisms in recent years has necessitated for better tools and techniques for the prediction and analysis of promoters in eukaryotic sequences. Many promoter prediction methods and tools have been developed to date but they have yet to provide acceptable predictive performance. One obvious criteria to improve on current methods is to devise a better system for selecting appropriate features of promoters that distinguish them from non-promoters. Secondly improved performance can be achieved by enhancing the predictive ability of the machine learning algorithms used. Results In this paper, a novel approach is presented in which 128 4-mer motifs in conjunction with a non-linear machine-learning algorithm utilising a Support Vector Machine (SVM are used to distinguish between promoter and non-promoter DNA sequences. By applying this approach to plant, Drosophila, human, mouse and rat sequences, the classification model has showed 7-fold cross-validation percentage accuracies of 83.81%, 94.82%, 91.25%, 90.77% and 82.35% respectively. The high sensitivity and specificity value of 0.86 and 0.90 for plant; 0.96 and 0.92 for Drosophila; 0.88 and 0.92 for human; 0.78 and 0.84 for mouse and 0.82 and 0.80 for rat demonstrate that this technique is less prone to false positive results and exhibits better performance than many other tools. Moreover, this model successfully identifies location of promoter using TATA weight matrix. Conclusion The high sensitivity and specificity indicate that 4-mer frequencies in conjunction with supervised machine-learning methods can be beneficial in the identification of RNA pol II promoters comparative to other methods.

How do household characteristics affect appliance usage? Application of conditional demand analysis to Japanese household data

International Nuclear Information System (INIS)

Matsumoto, Shigeru

2016-01-01

Although both appliance ownership and usage patterns determine residential electricity consumption, it is less known how households actually use their appliances. In this study, we conduct conditional demand analyses to break down total household electricity consumption into a set of demand functions for electricity usage, across 12 appliance categories. We then examine how the socioeconomic characteristics of the households explain their appliance usage. Analysis of micro-level data from the Nation Survey of Family and Expenditure in Japan reveals that the family and income structure of households affect appliance usage. Specifically, we find that the presence of teenagers increases both air conditioner and dishwasher use, labor income and nonlabor income affect microwave usage in different ways, air conditioner usage decreases as the wife's income increases, and microwave usage decreases as the husband's income increases. Furthermore, we find that households use more electricity with new personal computers than old ones; this implies that the replacement of old personal computers increases electricity consumption. - Highlights: •We conduct conditional demand analyses to study household appliance usage. •Micro-level data from the National Survey of Family and Expenditure in Japan are analyzed. •We show how household characteristics determine appliance usage. •High-income households use specific appliances less intensively than low-income households. •The replacement of old TVs and PCs lead to greater electricity consumption.

1982-01-01

Flow characteristics in relation to heat transfer characteristics in parallel channel with turbulence promoters were studied experimentally. Flow visualization experiments were made in paralle channel with one or two turbulence promoters for Reynolds number region of 100 lt = Resub(w) lt = 3,600. The vortex patterns behind one promoter were that a steady vortex was formed for low Reynolds number and vortex was shed for high Reynolds number,. For higher Reynolds number, it was observed that shedding vortex caused other vortices or disappeared itself randomly. The results indicate that the shedding vortices will augment heat transfer, whereas the steady vortex will give rise to deterioration in heat transfer. This inference agrees with the experimental results of Hishida et al. The results of two promoters experiment showed that the maximum performance of promoter would be attained at p/d -- 7. This agrees with the results formerly studied by other investigators. (author)

Affective state influences perception by affecting decision parameters underlying bias and sensitivity.

Lynn, Spencer K; Zhang, Xuan; Barrett, Lisa Feldman

2012-08-01

Studies of the effect of affect on perception often show consistent directional effects of a person's affective state on perception. Unpleasant emotions have been associated with a "locally focused" style of stimulus evaluation, and positive emotions with a "globally focused" style. Typically, however, studies of affect and perception have not been conducted under the conditions of perceptual uncertainty and behavioral risk inherent to perceptual judgments outside the laboratory. We investigated the influence of perceivers' experienced affect (valence and arousal) on the utility of social threat perception by combining signal detection theory and behavioral economics. We compared 3 perceptual decision environments that systematically differed with respect to factors that underlie uncertainty and risk: the base rate of threat, the costs of incorrect identification threat, and the perceptual similarity of threats and nonthreats. We found that no single affective state yielded the best performance on the threat perception task across the 3 environments. Unpleasant valence promoted calibration of response bias to base rate and costs, high arousal promoted calibration of perceptual sensitivity to perceptual similarity, and low arousal was associated with an optimal adjustment of bias to sensitivity. However, the strength of these associations was conditional upon the difficulty of attaining optimal bias and high sensitivity, such that the effect of the perceiver's affective state on perception differed with the cause and/or level of uncertainty and risk.

Do governance, equity characteristics, and venture capital nvolvement affect long-term wealth creation in U.S. health care and biotechnology IPOs?

Agency theory remains the dominant means of examining governance issues and ownership characteristics related to large organizations. Research in these areas within large organizations has increased our understanding, yet little is known about the influence that these mechanisms and characteristics have had on IPO firm performance. This study tests an agency perspective that venture capital involvement, governance and equity characteristics affect health care and biotechnology IPO firm performance. Our results indicate that there is no correlation between these factors and health care and biotechnology IPO wealth creation. For these entrepreneurs, our findings suggest a contingent approach for the use of these mechanisms.

There is sparse evidence regarding the effect of alcohol-advertising exposure on alcohol consumption among heavy drinkers. This study aimed to assess the immediate effects of alcohol-promoting and alcohol-warning video advertising on objective alcohol consumption in heavy-drinking young adults, and to examine underlying processes. Between-participants randomized controlled trial with three conditions. Two hundred and four young adults (aged 18-25) who self-reported as heavy drinkers were randomized to view one of three sets of 10 video advertisements that included either (1) alcohol-promoting, (2) alcohol-warning, or (3) non-alcohol advertisements. The primary outcome was the proportion of alcoholic beverages consumed in a sham taste test. Affective responses to advertisements, implicit alcohol approach bias, and alcohol attentional bias were assessed as secondary outcomes and possible mediators. Typical alcohol consumption, Internet use, and television use were measured as covariates. There was no main effect of condition on alcohol consumption. Participants exposed to alcohol-promoting advertisements showed increased positive affect and an increased approach/reduced avoidance bias towards alcohol relative to those exposed to non-alcohol advertisements. There was an indirect effect of exposure to alcohol-warning advertisements on reduced alcohol consumption via negative affect experienced in response to these advertisements. Restricting alcohol-promoting advertising could remove a potential influence on positive alcohol-related emotions and cognitions among heavy-drinking young adults. Producing alcohol-warning advertising that generates negative emotion may be an effective strategy to reduce alcohol consumption. Statement of contribution What is already known on this subject? Exposure to alcohol advertising has immediate and distal effects on alcohol consumption. There is some evidence that effects may be larger in heavy drinkers. Alcohol-warning advertising has

Previous studies have demonstrated that geriatric care employees are exposed to a large number of factors that can affect their levels of job satisfaction and occupational stress. Although working with elderly people is emotionally demanding, little research has been done on the role played by perceptions of emotional display rules, alongside more traditional work characteristics and individual factors, in the prediction of geriatric care employees' wellbeing. The aim of the present study was to examine the role played by work characteristics (job demands, job control, emotional display rules) and individual (affectivity) factors to predict job satisfaction and burnout among French geriatric care nurses. Questionnaires were sent to 891 employees working in 32 geriatric care centers in France. A total of 371 valid questionnaires (response rate: 41.60%) were analyzed using structural equation modeling techniques. Results revealed two main processes of burnout and job satisfaction among women geriatric care workers, namely a salutogenic process and a pathogenic process. As expected, negative affectivity, low job status, perceived negative display rules and job demands are involved in the pathogenic process; while positive affectivity, perceived positive display rules and job control are implied in the salutogenic one. More specifically, as expected, negative affectivity is a positive predictor of burnout, both directly and indirectly through its impact on perceived negative display rules and job demands. Moreover, negative affectivity was negatively related to job satisfaction. Simultaneously, positive affectivity can predict job satisfaction, both directly and indirectly through its impact on perceived positive display rules and job control. Positive affectivity is also a negative predictor of burnout. Practical implications are discussed to support intervention programs that develop healthy workplaces, and also to inform nurses about how to manage emotional display

Recent published data have shown the efficacy of gene therapy treatments of certain monogenic diseases. Risks of insertional oncogenesis, however, indicate the necessity of developing new vectors with weaker or cell-restricted promoters to minimize the trans-activation activity of integrated proviruses. We have inserted the proximal promoter of the vav proto-oncogene into self-inactivating lentiviral vectors (vav-LVs) and investigated the expression pattern and therapeutic efficacy of these vectors. Compared with other LVs frequently used in gene therapy, vav-LVs mediated a weak, though homogeneous and stable, expression in in vitro-cultured cells. Transplantation experiments using transduced mouse bone marrow and human CD34(+) cells confirmed the stable activity of the promoter in vivo. To investigate whether the weak activity of this promoter was compatible with a therapeutic effect, a LV expressing the Fanconi anemia A (FANCA) gene was constructed (vav-FANCA LV). Although this vector induced a low expression of FANCA, compared to the expression induced by a LV harboring the spleen focus-forming virus (SFFV) promoter, the two vectors corrected the phenotype of cells from a patient with FA-A with the same efficacy. We propose that self-inactivating vectors harboring weak promoters, such as the vav promoter, will improve the safety of gene therapy and will be of particular interest for the treatment of diseases where a high expression of the transgene is not required.

The author utilized semistructured interviews with 56 women to explore how a wide range of activities affected the development of the participants' same-sex attractions and relationships. The researcher was able to identify and describe some aspects of the process by which eight characteristics of activities that are more or less present in various social contexts have the potential to impact whether these contexts are more or less conducive or hindering to the development of women's same-sex attractions and relationships. Activities were more apt to nurture the development of the participants' same-sex attractions and relationships when the activity (a) included lesbians, (b) was composed primarily of women, (c) affirmed women, (d) facilitated bonding, (e) featured a climate of acceptance of lesbians/gays/bisexuals, (f) did not feature a climate that emphasized heteronormativity, (g) was perceived as gender neutral, and (h) generated or drew participants who were similar to each other.

Effects of Physician-directed Pharmaceutical Promotion on Prescription Behaviors: Longitudinal Evidence.

Science.gov (United States)

Datta, Anusua; Dave, Dhaval

2017-04-01

Spending on prescription drugs (Rx) represents one of the fastest growing components of US healthcare spending and has coincided with an expansion of pharmaceutical promotional spending. Most (83%) of Rx promotion is directed at physicians in the form of visits by pharmaceutical representatives (known as detailing) and drug samples provided to physicians' offices. Such promotion has come under increased public scrutiny, with critics contending that physician-directed promotion may play a role in raising healthcare costs and may unduly affect physicians' prescribing habits towards more expensive, and possibly less cost-effective, drugs. In this study, we bring longitudinal evidence to bear upon the question of how detailing impacts physicians' prescribing behaviors. Specifically, we examine prescriptions and promotion for a particular drug class based on a nationally representative sample of 150,000 physicians spanning 24 months. The use of longitudinal physician-level data allows us to tackle some of the empirical concerns in the extant literature, virtually all of which have relied on aggregate national data. We estimate fixed-effects specifications that bypass stable unobserved physician-specific heterogeneity and address potential targeting bias. In addition, we also assess differential effects at both the extensive and intensive margins of prescribing behaviors and differential effects across physician-level and market-level characteristics, questions that have not been explored in prior work. The estimates suggest that detailing has a significant and positive effect on the number of new scripts written for the detailed drug, with an elasticity magnitude of 0.06. This effect is substantially smaller than those in the literature based on aggregate information, suggesting that most of the observed relationship between physician-directed promotion and drug sales is driven by selection bias. We find that detailing impacts selective brand-specific demand but does

The impact of the distance-dependent promotional effect on the promotion cost sharing decision

Sheen, Gwo-Ji; Wang, Shih-Yen; Yeh, Yingchieh

2016-02-01

This paper considers the promotion cost sharing decision between a supplier and a retailer. The customer demand is affected by both national and local promotional effects while the local promotional effect on a customer is dependent on the distance between the retailer and this customer. We propose a continuous approximation approach to modelling the sum of the customer demand in the whole market area served by the retailer. A model is provided to help managers decide on the retail price, the local advertising expenditure, the national advertising expenditure, and the supplier participation rate, with consideration of the influence of distance on the promotional effect. We also find that the supplier's promotion cost sharing rate increases as the market size increases or the influence of distance on the promotional effect decreases. A numerical example is given to show that the nature of distance-dependent promotional effect has a significant impact on the decisions and profits.

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.

Full Text Available For a project to be considered successful it is necessary, besides a proper coordination, to be also done a good and wide promotion. In view of communication, promotion and maintenance ensures the organization's image. Disturbances occurring in any type of project, as a result of poor promotion, affect the image of the team and highlight the weaknesses in its management. Therefore, the promotion should be permanently monitored and evaluated. Cause-effect analysis is one of the ways we can identify some of nonconformities of the promotion process within a project.

The retail environment provides important opportunities for tobacco industry communication with current, former, and potential smokers. This study documented the extent of tobacco promotions at the retail point-of-sale and examined associations between the extent of tobacco promotions and relevant city and store characteristics. In each of 20 Ontario cities, 24 establishments were randomly selected from lists of convenience stores, gas stations, and grocery stores. Trained observers captured the range, type and intensity of tobacco promotions from April to July 2005. The extent of tobacco promotions was described using weighted descriptive statistics. Weighted t-tests and ANOVAs, and hierarchical linear modeling, were used to examine the relationships between tobacco promotions and city and store characteristics. Extensive tobacco promotions were found in Ontario stores one year prior to the implementation of a partial ban on retail displays, particularly in chain convenience stores, gas station convenience stores and independent convenience stores. The multivariate hierarchical linear model confirmed differences in the extent of tobacco promotions by store type (p point-of-sale. Public health messages about the harms of tobacco use may be compromised by the pervasiveness of these promotions.

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).

Full Text Available Background. Intraoral adjustment and polishing of dental ceramics often affect their surface characteristics, promoting increased roughness and consequent biofilm growth. This study correlated surface roughness to biofilm development with four commercially available ceramic materials. Methods. Four ceramic materials (Vita Enamic®, Lava™ Ultimate, Vitablocs Mark II, and Wieland Reflex® were prepared as per manufacturer instructions. Seventeen specimens of each material were adjusted and polished to simulate clinical intraoral procedures and another seventeen remained unaltered. Specimens were analysed by SEM imaging, confocal microscopy, and crystal violet assay. Results. SEM images showed more irregular surface topography in adjusted specimens than their respective controls. Surface roughness (Ra values were greater in all materials following adjustments. All adjusted materials with the exception of Vitablocs Mark II promoted significantly greater biofilm growth relative to controls. Conclusion. Simulated intraoral polishing methods resulted in greater surface roughness and increased biofilm accumulation.

PROMOTION OF MONTENEGRO THROUGH SPORTS

Full Text Available Modern social structures of Montenegro exist in a hypercomplex and very dynamic environment. The complexity and dynamism are, in part, a consequence of the general characteristics of the modern age, and in part, of the transition processes which have affected the Montenegrin society. The transition processes are taking place at all levels and subsystems of the community, and its sociological milieu is facing inevitability of adaptation and immersion in such processes and trends. There is no more positive promotion for a country than a sports promotion. There is no expert team, public relations agency or a lawyer than can win Montenegro a front page. We can talk about the importance of sports for the promotion of Montenegro from another point of view. If we compare the number of occurrences of names of the selected Montenegrin athletes with that of politicians, scientists or artists in different internet search engines, we will realize how great is the capacity of marketing potential that lies in Montenegrin sports and top athletes as representatives of the products and services with the label - Made in Montenegro. In addition to the success of the Montenegrin athletes globally, the promotion of Montenegro through sports is directly contributed by the major sporting events and contests, on account of which Montenegro presented itself not only as an excellent host and organizer, but also demonstrated the remarkable state and marketing capabilities and competencies. Reputation (image is not achieved overnight. Its semiological and symbolic charge includes all (visual, vocal, environmental, personal, active inputs, which need to be channelled and created. Indeed, continual work in creating and maintaining the image of Montenegro is a public relations function. With efficiently and professionally developed media and PR strategy, the modern state of Montenegro may expect to favourably position its image at the international scene, and to present its

Snail1 induces epithelial-to-mesenchymal transition and tumor initiating stem cell characteristics

International Nuclear Information System (INIS)

Dang, Hien; Ding, Wei; Emerson, Dow; Rountree, C Bart

2011-01-01

Tumor initiating stem-like cells (TISCs) are a subset of neoplastic cells that possess distinct survival mechanisms and self-renewal characteristics crucial for tumor maintenance and propagation. The induction of epithelial-mesenchymal-transition (EMT) by TGFβ has been recently linked to the acquisition of TISC characteristics in breast cancer. In HCC, a TISC and EMT phenotype correlates with a worse prognosis. In this work, our aim is to elucidate the underlying mechanism by which cells acquire tumor initiating characteristics after EMT. Gene and protein expression assays and Nanog-promoter luciferase reporter were utilized in epithelial and mesenchymal phenotype liver cancer cell lines. EMT was analyzed with migration/invasion assays. TISC characteristics were analyzed with tumor-sphere self-renewal and chemotherapy resistance assays. In vivo tumor assay was performed to investigate the role of Snail1 in tumor initiation. TGFβ induced EMT in epithelial cells through the up-regulation of Snail1 in Smad-dependent signaling. Mesenchymal liver cancer post-EMT demonstrates TISC characteristics such as tumor-sphere formation but are not resistant to cytotoxic therapy. The inhibition of Snail1 in mesenchymal cells results in decreased Nanog promoter luciferase activity and loss of self-renewal characteristics in vitro. These changes confirm the direct role of Snail1 in some TISC traits. In vivo, the down-regulation of Snail1 reduced tumor growth but was not sufficient to eliminate tumor initiation. In summary, TGFβ induces EMT and TISC characteristics through Snail1 and Nanog up-regulation. In mesenchymal cells post-EMT, Snail1 directly regulates Nanog expression, and loss of Snail1 regulates tumor growth without affecting tumor initiation

2017-10-01

The mouse Shb gene coding for the Src Homology 2-domain containing adapter protein B has recently been placed in context of BCRABL1-induced myeloid leukemia in mice and the current study was performed in order to relate SHB to human acute myeloid leukemia (AML). Publicly available AML databases were mined for SHB gene expression and patient survival. SHB gene expression was determined in the Uppsala cohort of AML patients by qPCR. Cell proliferation was determined after SHB gene knockdown in leukemic cell lines. Despite a low frequency of SHB gene mutations, many tumors overexpressed SHB mRNA compared with normal myeloid blood cells. AML patients with tumors expressing low SHB mRNA displayed longer survival times. A subgroup of AML exhibiting a favorable prognosis, acute promyelocytic leukemia (APL) with a PMLRARA translocation, expressed less SHB mRNA than AML tumors in general. When examining genes co-expressed with SHB in AML tumors, four other genes ( PAX5, HDAC7, BCORL1, TET1) related to leukemia were identified. A network consisting of these genes plus SHB was identified that relates to certain phenotypic characteristics, such as immune cell, vascular and apoptotic features. SHB knockdown in the APL PMLRARA cell line NB4 and the monocyte/macrophage cell line MM6 adversely affected proliferation, linking SHB gene expression to tumor cell expansion and consequently to patient survival. It is concluded that tumor SHB gene expression relates to AML survival and its subgroup APL. Moreover, this gene is included in a network of genes that plays a role for an AML phenotype exhibiting certain immune cell, vascular and apoptotic characteristics.

Stimulating innovative research in health promotion.

Larouche, Annie; Potvin, Louise

2013-06-01

The Global Working Group on Health Promotion Research (GWG HPR) of the International Union for Health Promotion and Education (IUHPE) presents a collection of four articles illustrating innovative avenues for health promotion research. This commentary synthesizes the contributions of these articles while attempting to define the contours of research in health promotion. We propose that innovation in research involves the adoption of a reflexive approach wherein consideration of context plays different roles. The reflexive process consists of questioning what is taken for granted in the conceptualization and operationalization of research. It involves linking research findings and its theoretical foundations to characteristics and goals of the field and observed realities, while orienting reflection on specific objects. The reflexive nature of the research activity is of paramount importance for innovation in health promotion. With the publication of this series, the GWG HPR wishes to strengthen health promotion research capacity at the global level and reaffirm health promotion as a specific research domain.

Frets, P G; Verhage, F; Niermeijer, M F

1991-09-01

An in-depth, recorded interview of 30 couples 2-3 years after genetic counseling explored the characteristics of the postcounseling decision-making process, including the role of guilt feelings towards the proband. The study concerned couples with an affected child, sib, or spouse. Results were evaluated by 2 to 4 judges. In contrast to other studies, a generally unstructured decision-making process was found whereby guilt feelings played a significant role in more than half the couples. Guilt feelings were more predominant in couples with an affected sib than in those with an affected spouse. Lack of structure did not seem to complicate the decision-making process. Therefore, authors do not advocate promotion of structuring the decision-making process. Genetic counselors might focus on understanding counselees' feelings concerning the reproductive decision. Acceptance of apparently irrational considerations is particularly important, because these feelings indicate the influence of unconscious motives. Another important aspect of supporting counselees is to understand the role played by guilt feelings toward parents or an affected sib.

Comparative analyses of bidirectional promoters in vertebrates

Taylor James

2008-05-01

Full Text Available Abstract Background Orthologous genes with deep phylogenetic histories are likely to retain similar regulatory features. In this report we utilize orthology assignments for pairs of genes co-regulated by bidirectional promoters to map the ancestral history of the promoter regions. Results Our mapping of bidirectional promoters from humans to fish shows that many such promoters emerged after the divergence of chickens and fish. Furthermore, annotations of promoters in deep phylogenies enable detection of missing data or assembly problems present in higher vertebrates. The functional importance of bidirectional promoters is indicated by selective pressure to maintain the arrangement of genes regulated by the promoter over long evolutionary time spans. Characteristics unique to bidirectional promoters are further elucidated using a technique for unsupervised classification, known as ESPERR. Conclusion Results of these analyses will aid in our understanding of the evolution of bidirectional promoters, including whether the regulation of two genes evolved as a consequence of their proximity or if function dictated their co-regulation.

Military Families’ Perceptions of Neighborhood Characteristics Affecting Reintegration: Development of an Aggregate Measure

Beehler, Sarah; Ahern, Jennifer; Balmer, Brandi; Kuhlman, Jennifer

2017-01-01

This pilot study evaluated the validity and reliability of an Experience of Neighborhood (EON) measure developed to assess neighborhood characteristics that shape reintegration opportunities for returning service members and their families. A total of 91 post-9/11 veterans and spouses completed a survey administered at the Minnesota State Fair. Participants self-reported on their reintegration status (veterans), social functioning (spouses), social support, and mental health. EON factor structure, internal consistency reliability, and validity (discriminant, content, criterion) were analyzed. The EON measure showed adequate reliability, discriminant validity, and content validity. More work is needed to assess criterion validity because EON scores were not correlated with scores on a Census-based index used to measure quality of military neighborhoods. The EON may be useful in assessing broad local factors influencing health among returning veterans and spouses. More research is needed to understand geographic variation in neighborhood conditions and how those affect reintegration and mental health for military families. PMID:28936370

SCM-198 is an alkaloid found only in Herba leonuri and it has been reported to possess considerable neuroprotective effects in animal models of ischemic stroke, Parkinson's disease and Alzheimer's disease (AD). In this study, we demonstrated for the first time that 3-month oral SCM-198 treatment could significantly improve both recognition and spatial memory, inhibit microgliosis and promote neuronal survival in amyloid-β protein precursor and presenilin-1(AβPP/PS1) double-transgenic mice without affecting amyloid-β (Aβ) burden. In addition, decreases in cAMP-response element-binding protein (CREB) phosphorylation, brain-derived neurotrophic factor (BDNF) and tropomyosin-related kinase B (TrkB) phosphorylation were attenuated by SCM-198 both in vivo and in primary cortical neurons, which could be blocked by protein kinase A (PKA) inhibitors, suggesting the involvement of upstream PKA in enhancing the BDNF/TrkB/CREB signaling by SCM-198. Our results indicate that SCM-198, a drug that could promote neuronal survival and enhance BDNF/TrkB/CREB signaling, has beneficial effects on behavioral and biochemical alterations without affecting Aβ burden in AβPP/PS1 mice and might become a potential drug candidate for AD treatment in the future.

Full Text Available The reckless consumption of nature to respond to any need has led to the disruption of natural balance and nearly extinction of environmental resources. Environmental problems created by the damage to the structure of nature not only affect the ecological system, but also pose an immense challenge for human health. Hence, the consumers who have become aware that resources and living spaces to maintain their living conditions have been increasingly declining are inclined to adopt a more sensitive attitude in consumption process. Businesses have also turned to green advertising for the promotion of their products and services to strengthen their presence and elude competition with other businesses under these circumstances. This study aims to identify the factors that affect the consumer attitudes of the employed individuals on green advertisements for the businesses, and examine their differences according to demographic features. The reason for the selection of employed individuals is assumption that they will be effective of consumers having purchasing income especially in qualified green product purchasing decisions. The questionnaire form designed for this purpose was conducted on 400 individuals selected through convenience sampling method among people living in central district of Kastamonu. It was found that the factors affecting these employed individuals attitudes towards green product advertisements significantly differ according to gender, marital status, age, education and occupation

A lysimeter study was conducted to investigate the effect of irrigation with saline water on soil chemical characteristics at two depth (0-20) and (20-40 cm).Both fertilized (60, 120 KgN/ha) and unfertilized (0) soil were simulated in a total of 84 lysimeter. Data indicated that the electric conductivity (EC) values tended to increase with time intervals also EC-values as affected by soil depth after 105 days were high in 20 cm depth as compared to 40 cm depth. Chloride concentration did not reflect great variations as affected by time of nitrogen application where the values were nearly closed to each other. At the end of the experiment, much of Cl - content was occurred in the second layer of soil depth (20-40) as compared to depth of 0-20 cm. This was the case under all salinity levels. The irrigation with fresh water did not reflect any significant different in EC values between 120 KgN/ha , 60 KgN/ha or soil depth, however, it tend to increase with increasing water salinity levels. There were no much differences between the nitrogen application time (T1, T2 and T3). In contrast with Cl - , sodium was remained in the upper layer of 0-20 cm soil depth but still increase with increasing water salinity levels.

Large-scale losses of honey bee colonies represent a poorly understood problem of global importance. Both biotic and abiotic factors are involved in this phenomenon that is often associated with high loads of parasites and pathogens. A stronger impact of pathogens in honey bees exposed to neonicotinoid insecticides has been reported, but the causal link between insecticide exposure and the possible immune alteration of honey bees remains elusive. Here, we demonstrate that the neonicotinoid insecticide clothianidin negatively modulates NF-κB immune signaling in insects and adversely affects honey bee antiviral defenses controlled by this transcription factor. We have identified in insects a negative modulator of NF-κB activation, which is a leucine-rich repeat protein. Exposure to clothianidin, by enhancing the transcription of the gene encoding this inhibitor, reduces immune defenses and promotes the replication of the deformed wing virus in honey bees bearing covert infections. This honey bee immunosuppression is similarly induced by a different neonicotinoid, imidacloprid, but not by the organophosphate chlorpyriphos, which does not affect NF-κB signaling. The occurrence at sublethal doses of this insecticide-induced viral proliferation suggests that the studied neonicotinoids might have a negative effect at the field level. Our experiments uncover a further level of regulation of the immune response in insects and set the stage for studies on neural modulation of immunity in animals. Furthermore, this study has implications for the conservation of bees, as it will contribute to the definition of more appropriate guidelines for testing chronic or sublethal effects of pesticides used in agriculture.

As workplaces increasingly adopt proactive programs directed toward employee health issues, the interrelation between different programs becomes an important issue. Of interest here is the "synergy" in patterns of program adoption between employee assistance programs (EAPs) and health promotion activities (HPAs). We utilize the 1985 National Survey of Worksite Health Promotion Activities (N = 1358) for analyses of the dual presence of EAPs and HPAs, and in multivariate analyses we consider factors affecting such dual presence. The data suggest that synergy occurs, with EAP adoption appearing to influence HPA adoption to a greater extent than the reverse. In multivariate analyses, synergy is confirmed by the finding that, among a variety of relevant organizational characteristics, EAP presence and HPA presence are the best predictors of each other's presence. The analyses also indicate that there is minimal commonality in program ingredients across organizations reporting the presence of HPAs. Implications of the data for the future development of these two programming strategies are discussed.

Full Text Available Contemporary marketing takes place in the field of permanent interconnection, of instant information and immediate rewards. Communication through marketing promotion will take these characteristics into account or will be just an inefficient spending. The Romanian market is no different from the global one. Marketing promotion currently has new tools that lead to new challenges in that it makes use of traditional, yet pow erful forms, but also absolute ways of communication. The Romanian promotion is helped today by these tools, but its task is more complex than it was a decade ago .

The low level of foreign genes' expression in transgenic plants is a key factor that limits plant genetic engineering.Because of the critical regulatory activity of the promoters on gene transcription,they are studied extensively to improve the efficiency of the plant transgenic system.The constitutive promoters,such as CaMV 35S promoter,are usually used in plant genetic engineering.But those constitutive promoters continuously express their downstream genes during the whole life span in all the tissues of the host plants.This is not only wasteful to host plant's energy,but also harmful to host plants and usually affects their agronomic characteristics.In contrast,the seed-specific promoter only expresses its downstream genes from mid to late stage of seed maturation,and there is no expression or much lower expression in other tissues.So the seed-specific promoters are distinguished for their improvement and what they have brought to plant quality engineering.The aim of this article is to characterize a new seed-specific promoter and improve grain quality.The promoter region of β-conglycinin α-subunit gene was isolated from the genomic DNA of soybean Jilin 43 by PCR method,and successfully extended this fragment by TAIL PCR method and obtained the promoter fragment BCSP666.Sequencing analysis showed that the cloned fragment BCSP666 contained all of the motifs,such as RY repeat element,AG/CCCCA motif,TACACAT motif,ACGTmotif,A/T rich motif and E-box etc.,which constituted the seed-specific promoter activity.Based on this sequencing analysis,the seed-specific promoter activity of the fragment BCSP666 was predicted.And then the seed-specific expression vector pBI121-666,which contained GUS reporter gene,was constructed with the fragment BCSP666.Transformation of Arabidopsis thaliana plants by Agrobacterium-mediated floral-dip method with the recombined vector pBI121-666was conducted.The transgenic plants were selected on the kanamycin-resistant MS medium

Eriksson, Andrea; Axelsson, Runo; Axelsson, Susanna Bihari

2011-01-01

To describe and analyse different views of health promoting leadership among actors involved in workplace health promotion in eight Swedish municipalities. Twenty individuals were interviewed and their views were analysed according to the methodology of phenomenograpic research, exploring how health promoting leadership was described, what motives were expressed, and what critical conditions were perceived for developing such leadership. The informants described health promoting leadership in three ways: organising health promoting activities, having a supportive leadership style, and developing a health promoting workplace. The motives mentioned for developing health promoting leadership were instrumental motives and improved health. The critical conditions for health promoting leadership were organisational conditions, characteristics of individual managers, and support to managers. It seems that the concept of health promoting leadership was often used to link ideas about good leadership to the health of employees. Organisational goals and management trends may also have influenced the motives as well as the conditions for development of health promoting leadership.

Purpose As children mature, changes in voice spectral characteristics covary with changes in speech, language, and behavior. Spectral characteristics were manipulated to alter the perceived ages of talkers’ voices while leaving critical acoustic-prosodic correlates intact, to determine whether perceived age differences were associated with differences in judgments of prosodic, segmental, and talker attributes. Method Speech was modified by lowering formants and fundamental frequency, for 5-year-old children’s utterances, or raising them, for adult caregivers’ utterances. Next, participants differing in awareness of the manipulation (Exp. 1a) or amount of speech-language training (Exp. 1b) made judgments of prosodic, segmental, and talker attributes. Exp. 2 investigated the effects of spectral modification on intelligibility. Finally, in Exp. 3 trained analysts used formal prosody coding to assess prosodic characteristics of spectrally-modified and unmodified speech. Results Differences in perceived age were associated with differences in ratings of speech rate, fluency, intelligibility, likeability, anxiety, cognitive impairment, and speech-language disorder/delay; effects of training and awareness of the manipulation on ratings were limited. There were no significant effects of the manipulation on intelligibility or formally coded prosody judgments. Conclusions Age-related voice characteristics can greatly affect judgments of speech and talker characteristics, raising cautionary notes for developmental research and clinical work. PMID:23275414

Rearing of yellow mealworm (Tenebrio molitor L.) will provide good animal nutrition for astronauts in a bioregenerative life support system. In this study, growth and biomass conversion data of T. molitor larvae were tested for calculating the stoichiometric equation of its growth. Result of a respiratory quotient test proved the validity of the equation. Fiber had the most reduction in mass during T. molitor‧s consumption, and thus it is speculated that fiber is an important factor affecting larval growth of T. molitor. In order to further confirm this hypothesis and find out a proper feed fiber content, T. molitor larvae were fed on diets with 4 levels of fiber. Larval growth, development and respiration in each group were compared and analyzed. Results showed that crude-fiber content of 5% had a significant promoting effect on larvae in early instars, and is beneficial for pupa eclosion. When fed on feed of 5-10% crude-fiber, larvae in later instars reached optimal levels in growth, development and respiration. Therefore, we suggest that crude fiber content in feed can be controlled within 5-10%, and with the consideration of food palatability, a crude fiber of 5% is advisable.

Promoting resilience is an aspect of psychosocial care that affects patient and whole-family well-being. There is little consensus about how to define or promote resilience during and after pediatric cancer. The aims of this study were (1) to review the resilience literature in pediatric cancer settings; (2) to qualitatively ascertain caregiver-reported perceptions of resilience; and (3) to develop an integrative model of fixed and mutable factors of resilience among family members of children with cancer, with the goal of enabling better study and promotion of resilience among pediatric cancer families. The study entailed qualitative analysis of small group interviews with eighteen bereaved parents and family members of children with cancer treated at Seattle Children's Hospital. Small-group interviews were conducted with members of each bereaved family. Participant statements were coded for thematic analysis. An integrative, comprehensive framework was then developed. Caregivers' personal appraisals of the cancer experience and their child's legacy shape their definitions of resilience. Described factors of resilience include baseline characteristics (i.e., inherent traits, prior expectations of cancer), processes that evolve over time (i.e., coping strategies, social support, provider interactions), and psychosocial outcomes (i.e., post-traumatic growth and lack of psychological distress). These elements were used to develop a testable model of resilience among family members of children with cancer. Resilience is a complex construct that may be modifiable. Once validated, the proposed framework will not only serve as a model for clinicians, but may also facilitate the development of interventions aimed at promoting resilience in family members of children with cancer.

Evidence indicates that a healthy lifestyle can reduce cardiovascular disease risk, yet many people engage in unhealthy behaviors. New technologies such as coronary artery calcium (CAC) screening detect atherosclerosis before clinical disease is manifested. Knowledge of an abnormal finding could provide the "teachable moment" to enhance motivation for change. The aim of this study was to examine how knowledge of CAC score affects risk perception, likelihood of taking action, and health-promoting behavior change in persons at high risk for cardiovascular disease. This study used a descriptive prospective design with 174 high-risk adults (≥3 major risk factors) recruited at a radiology center offering CAC scans. Baseline self-report surveys using the Perception of Risk of Heart Disease Scale, the Benefits and Barriers Scale, the Quality of Life Index, and the Health-Promoting Lifestyle Profile II were completed immediately after a screening CAC scan but before results were known. Follow-up occurred 3 months later using mailed packets. Participants' mean age was 58 years; 62% were men, 89% were white, and most were well educated. There was no significant change in risk perception scores over time or between groups, except for a positive interaction in the moderate-risk group (CAC scores of 101-400) (P = .004). Quality of life remained unchanged. Health-promoting behavior changes increased in all groups over time (P behavior change were perceived barriers (β = -.41; P Knowledge of CAC score does impact risk perception for some at-risk groups. This knowledge does enhance motivation for behavior change. Knowledge of CAC score does not impact quality of life. It is hoped that through improved understanding of the effect of CAC scoring on behavior change, nurses can better assist patients to modify behaviors during teachable moments.

To study the effect of root-zone pH on characteristic responses of NH4+ -fed plants, soybeans (Glycine max inverted question markL. inverted question mark Merr. cv. Ransom) were grown in flowing solution culture for 21 d on four sources of N (1.0 mol m-3 NO3-, 0.67 mol m-3 NO3- plus 0.33 mol m-3 NH4+, 0.33 mol m-3 NO3- plus 0.67 mol m-3 NH4+, and 1.0 mol m-3 NH4+) with nutrient solutions maintained at pH 6.0, 5.5, 5.0, and 4.5. Amino acid concentration increased in plants grown with NH4+ as the sole source of N at all pH levels. Total amino acid concentration in the roots of NH4+ -fed plants was 8 to 10 times higher than in NO3(-)-fed plants, with asparagine accounting for more than 70% of the total in the roots of these plants. The concentration of soluble carbohydrates in the leaves of NH4+ -fed plants was greater than that of NO3(-)-fed plants, but was lower in roots of NH4+ -fed plants, regardless of pH. Starch concentration was only slightly affected by N source or root-zone pH. At all levels of pH tested, organic acid concentration in leaves was much lower when NH4+ was the sole N source than when all or part of the N was supplied as NO3-. Plants grown with mixed NO3- plus NH4+ N sources were generally intermediate between NO3(-)- and NH4+ -fed plants. Thus, changes in tissue composition characteristic of NH4+ nutrition when root-zone pH was maintained at 4.5 and growth was reduced, still occurred when pH was maintained at 5.0 or above, where growth was not affected. The changes were slightly greater at pH 4.5 than at higher pH levels.

Prescribing behavior of physicians affected by many factors. The present study is aimed at discovering the simultaneous effects of the evaluated factors (including: price, promotion and demographic characteristics of physicians) and quantification of these effects. In order to estimate these effects, Fluvoxamine (an antidepressant drug) was selected and the model was figured out by panel data method in econometrics. We found that insurance and advertisement respectively are the most effective on increasing the frequency of prescribing, whilst negative correlation was observed between price and the frequency of prescribing a drug. Also brand type is more sensitive to negative effect of price than to generic. Furthermore, demand for a prescription drug is related with physician demographics (age and sex). According to the results of this study, pharmaceutical companies should pay more attention to the demographic characteristics of physicians (age and sex) and their advertisement and pricing strategies.

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

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.

SCM-198 Ameliorates Cognitive Deficits, Promotes Neuronal Survival and Enhances CREB/BDNF/TrkB Signaling without Affecting Aβ Burden in AβPP/PS1 Mice

Full Text Available SCM-198 is an alkaloid found only in Herba leonuri and it has been reported to possess considerable neuroprotective effects in animal models of ischemic stroke, Parkinson’s disease and Alzheimer’s disease (AD. In this study, we demonstrated for the first time that 3-month oral SCM-198 treatment could significantly improve both recognition and spatial memory, inhibit microgliosis and promote neuronal survival in amyloid-β protein precursor and presenilin-1(AβPP/PS1 double-transgenic mice without affecting amyloid-β (Aβ burden. In addition, decreases in cAMP-response element-binding protein (CREB phosphorylation, brain-derived neurotrophic factor (BDNF and tropomyosin-related kinase B (TrkB phosphorylation were attenuated by SCM-198 both in vivo and in primary cortical neurons, which could be blocked by protein kinase A (PKA inhibitors, suggesting the involvement of upstream PKA in enhancing the BDNF/TrkB/CREB signaling by SCM-198. Our results indicate that SCM-198, a drug that could promote neuronal survival and enhance BDNF/TrkB/CREB signaling, has beneficial effects on behavioral and biochemical alterations without affecting Aβ burden in AβPP/PS1 mice and might become a potential drug candidate for AD treatment in the future.

To examine the workforce, workplace, psychosocial and health characteristics of nurses and midwives in relation to their reported use of sickness absence described as 'mental health days'. The occupational stress associated with the nursing profession is increasingly recognized and nurse/midwifery absenteeism is a significant global problem. Taking a 'mental health day' as sickness absence is a common phenomenon in Australian health care. No previous studies have empirically explored the characteristics of nurses and midwives using such sickness absence. Online cross-sectional survey. Survey comprising validated tools and questions on workplace and health characteristics was distributed to nurses and midwives in New South Wales, Australia, between May 2014 - February 2015. Sample characteristics were reported using descriptive statistics. Factors independently predictive of 'mental health day' reportage were determined using logistic regression. Fifty-four percentage of the n = 5041 nurse and midwife respondents took 'mental health days'. Those affected were significantly more likely to be at younger ages, working shifts with less time sitting at work; to report workplace abuse and plans to leave; having been admitted to hospital in previous 12 months; to be current smokers; to report mental health problems, accomplishing less due to emotional problems and current psychotropic medication use. Specific characteristics of nurses and midwives who report taking 'mental health day' sickness absence offer healthcare administrators and managers opportunities for early identification and intervention with workplace measures and support frameworks to promote well-being, health promotion and safety. © 2016 The Authors.

In 2008, in Central Italy, a low dosage of CPPU solution, 4 μL L(-1) (6 hL/ha), was sprayed on the canopy of vines of 'Hayward' kiwifruit, at the "break of sepals", about one week before anthesis, to study its effects on fruit weight/size and on qualitative and nutritional characteristics. At harvest, CPPU, with respect to control, significantly increased the fresh weight by about 12% (+12.6 g fruit(-1)) and consequently the yield per vine, without affecting fruit shape, firmness, dry matter (%), total soluble solids, glucose, fructose, sucrose, starch, citrate, malate, vitamin C and soluble and insoluble oxalic acid. After 3 months of storage, CPPU-treated kiwifruits and the control fruit showed no difference in dry matter content, fruit firmness and total soluble solids. The results indicate that a low dosage of CPPU applied in pre-anthesis can improve fruit weight/size without any negative effect on fruit qualitative and nutritional characteristics.

Green, Emily P; Gruppuso, Philip A

2017-06-01

The function of medical school entities that determine student advancement or dismissal has gone largely unexplored. The decision making of 'academic progress' or student promotions committees is examined using a theoretical framework contrasting ethics of justice and care, with roots in the moral development work of theorists Kohlberg and Gilligan. To ascertain promotions committee members' conceptualisation of the role of their committee, ethical orientations used in member decision making, and student characteristics most influential in that decision making. An electronic survey was distributed to voting members of promotions committees at 143 accredited allopathic medical schools in the USA. Descriptive statistics were calculated and data were analysed by gender, role, institution type and class size. Respondents included 241 voting members of promotions committees at 55 medical schools. Respondents endorsed various promotions committee roles, including acting in the best interest of learners' future patients and graduating highly qualified learners. Implementing policy was assigned lower importance. The overall pattern of responses did not indicate a predominant orientation toward an ethic of justice or care. Respondents indicated that committees have discretion to take individual student characteristics into consideration during deliberations, and that they do so in practice. Among the student characteristics with the greatest influence on decision making, professionalism and academic performance were paramount. Eighty-five per cent of participants indicated that they received no training. Promotions committee members do not regard orientations of justice and care as being mutually exclusive and endorse an array of statements regarding the committee's purpose that may conflict with one another. The considerable variance in the influence of student characteristics and the general absence of committee member training indicate a need for clear delineation of the

Word-of-mouth (WOM) refers to communication among consumers, which greatly influences the marketing strategies of dental clinics. This study aimed to explore factors that affect use of WOM by dental patients and to analyse their pathways. The participants were 520 outpatients from four private dental clinics. Data were obtained from a survey using self-reported questionnaires, which included questions regarding seven latent variables: five exogenous variables, including medical service quality (physical environment, customer service, patient relationship quality) and individual characteristic variables (opinion leader tendency, social hub tendency); and two endogenous variables (intention to recommend, WOM experience). Statistical analysis was performed using structural equation modelling. Significant associations were found in the pathways between relationship quality and intention to recommend, intention to recommend and WOM, and opinion leader tendency and WOM (P < 0.001). Higher patient relationship quality and higher intention to recommend were related to positive WOM, as was higher opinion leader tendency. Improving patient relationship quality can promote positive WOM for dental clinics. Strategies are needed to promote a positive perception of dental clinics by effectively responding to the views of patients with strong opinion leader tendencies. © 2018 FDI World Dental Federation.

The aims are to study personality characteristics of patients with memory complaints and to assess the presence of objective (OMI) versus subjective (SMI) memory impairment, the affective status, as well as potential gender differences. The patients were assessed by means of a neuropsychiatric examination and a neuropsychological test-battery. The Swedish version of the revised NEO Personality Inventory (NEO PI-R) and the Hospital Anxiety and Depression Scale (HADS) were used. The 57 patients (38 women, 19 men, mean age 56.9) differed from the Swedish normative group in three of the five personality factors: neuroticism, extraversion and agreeableness. This was mainly because of the scores of the female patients. Approximately half of the patients had OMI. No differences regarding personality factors or affective status were found between OMI and SMI patients. The female patients scored significantly higher than the male patients on symptoms of anxiety and depression. Neuroticism and symptoms of depression interacted with memory performance and gender. Our findings demonstrate the importance of applying an objective assessment of memory functions and a gender perspective when studying patients with memory complaints.

How internal drainage affects evaporation dynamics from soil surfaces ?

Science.gov (United States)

Or, D.; Lehmann, P.; Sommer, M.

2017-12-01

Following rainfall, infiltrated water may be redistributed internally to larger depths or lost to the atmosphere by evaporation (and by plant uptake from depths at longer time scales). A large fraction of evaporative losses from terrestrial surfaces occurs during stage1 evaporation during which phase change occurs at the wet surface supplied by capillary flow from the soil. Recent studies have shown existence of a soil-dependent characteristic length below which capillary continuity is disrupted and a drastic shift to slower stage 2 evaporation ensues. Internal drainage hastens this transition and affect evaporative losses. To predict the transition to stage 2 and associated evaporative losses, we developed an analytical solution for evaporation dynamics with concurrent internal drainage. Expectedly, evaporative losses are suppressed when drainage is considered to different degrees depending on soil type and wetness. We observe that high initial water content supports rapid drainage and thus promotes the sheltering of soil water below the evaporation depth. The solution and laboratory experiments confirm nonlinear relationship between initial water content and total evaporative losses. The concept contributes to establishing bounds on regional surface evaporation considering rainfall characteristics and soil types.

In this study, we explored what may determine, or predict, United States military women's health promotion behaviors. Using a descriptive correlational design grounded in Pender's Health Promotion model, 491 military women completed instruments measuring their demographic variables, perception of health, definition of health, self-efficacy, and interpersonal influences to determine the significant factors affecting participation in health promotion activities. The outcome indicated that self-efficacy and interpersonal influences were the most influential in determining health promotion. This research illuminates some of the challenges working women face in meeting health promotion activities and how best to support their ability to participate in healthy behaviors.

Full Text Available The importance of laboratory scale ceramic membrane preparation using sol-gel technique with pore sizes in the range of 1-10nm is reviewed. Parameters affecting the characteristics of membrane during membrane development are highlighted and discussed in detail. Experimental results from literatures have shown that the correct amount of acid, water, PVA, appropriate membrane thickness, proper control of drying rate, and appropriate temperature profile selection during sintering process are necessary in order to acquire sufficient strength and reduce the formation of crack in the membrane. The different temperature setting during sintering process also influences the size of pore formed.Key Words: Sol-Gel, Inorganic Membrane, Ceramic Membrane, Gas Permeation, Sintering, Sol Properties, Membrane Morphologies, Pore Size Distribution.

Sexuality in Older Couples: Individual and Dyadic Characteristics.

Waite, Linda J; Iveniuk, James; Laumann, Edward O; McClintock, Martha K

2017-02-01

Sexuality is a key component of health and functioning that changes with age. Although most sexual activity takes place with a partner, the majority of research on sexuality has focused on individuals. In this paper, we focused on the sexual dyad. We proposed and tested a conceptual model of the predictors of partnered sexual activity in older adulthood. This model began with the personality of each of the partners, which affects individuals' views of sex and characteristics of the partnership, which in turn affected sexual expression in the couple. We measured a key feature of personality, Positivity, which reflected the individual's tendency to present his or herself positively in social situations. This trait, we posited, increased frequency of sex through increased desire for sex, and the subjective importance of sex to each member of the couple. In this model, Positivity also impacted characteristics of the relationship that promoted dyadic sexual behavior. These processes differed for men and women in the model. We tested this model with data from the National Social Life, Health and Aging Project, which conducted personal interviews with both partners in 940 American dyads (average male age 72; average female age 69). We found that couples in which the husbands' (but not wives') were high in Positivity show higher levels of sexual activity, and that this association was partially mediated by dimensions of relationship quality, but more so by individual factors such as thinking about sex and believing sex is important.

Exploiting nucleotide composition to engineer promoters.

Directory of Open Access Journals (Sweden)

Manfred G Grabherr

Full Text Available The choice of promoter is a critical step in optimizing the efficiency and stability of recombinant protein production in mammalian cell lines. Artificial promoters that provide stable expression across cell lines and can be designed to the desired strength constitute an alternative to the use of viral promoters. Here, we show how the nucleotide characteristics of highly active human promoters can be modelled via the genome-wide frequency distribution of short motifs: by overlapping motifs that occur infrequently in the genome, we constructed contiguous sequence that is rich in GC and CpGs, both features of known promoters, but lacking homology to real promoters. We show that snippets from this sequence, at 100 base pairs or longer, drive gene expression in vitro in a number of mammalian cells, and are thus candidates for use in protein production. We further show that expression is driven by the general transcription factors TFIIB and TFIID, both being ubiquitously present across cell types, which results in less tissue- and species-specific regulation compared to the viral promoter SV40. We lastly found that the strength of a promoter can be tuned up and down by modulating the counts of GC and CpGs in localized regions. These results constitute a "proof-of-concept" for custom-designing promoters that are suitable for biotechnological and medical applications.

How task characteristics and social support relate to managerial learning: empirical evidence from Dutch home care.

Ouweneel, A P Else; Taris, Toon W; Van Zolingen, Simone J; Schreurs, Paul J G

2009-01-01

Researchers have revealed that managers profit most from informal and on-the-job learning. Moreover, research has shown that task characteristics and social support affect informal learning. On the basis of these insights, the authors examined the effects of task characteristics (psychological job demands, job control) and social support from the supervisor and colleagues on informal on-the-job learning among 1588 managers in the Dutch home-care sector. A regression analysis revealed that high demands, high control, and high colleague and supervisor support were each associated with high levels of informal learning. The authors found no evidence for statistical interactions among the effects of these concepts. They concluded that to promote managers' informal workplace learning, employers should especially increase job control.

The termination of discontinuous gas exchange cycles (DGCs) in severely dehydrated insects casts doubt on the generality of the hygric hypothesis, which posits that DGCs evolved as a water conservation mechanism. We followed DGC characteristics in the two density-dependent phases of the desert locust Schistocerca gregaria throughout exposure to an experimental treatment of combined dehydration and starvation stress, and subsequent rehydration. We hypothesized that, under stressful conditions, the more stress-resistant gregarious locusts would maintain DGCs longer than solitary locusts. However, we found no phase-specific variations in body water content, water loss rates (total and respiratory) or timing of stress-induced abolishment of DGCs. Likewise, locusts of both phases re-employed DGCs after ingesting comparable volumes of water when rehydrated. Despite comparable water management performances, the effect of exposure to stressful experimental conditions on DGC characteristics varied significantly between gregarious and solitary locusts. Interburst duration, which is affected by the ability to buffer CO2, was significantly reduced in dehydrated solitary locusts compared with gregarious locusts. Moreover, despite similar rehydration levels, only gregarious locusts recovered their initial CO2 accumulation capacity, indicating that cycle characteristics are affected by factors other than haemolymph volume. Haemolymph protein measurements and calculated respiratory exchange ratios suggest that catabolism of haemolymph proteins may contribute to a reduced haemolymph buffering capacity, and thus a compromised ability for CO2 accumulation, in solitary locusts. Nevertheless, DGC was lost at similar hydration states in the two phases, suggesting that DGCs are terminated as a result of inadequate oxygen supply to the tissues. © 2015.

Postnatal myofibre characteristics and muscle mass are largely determined during fetal development and may be significantly affected by epigenetic parent-of-origin effects. However, data on such effects in prenatal muscle development that could help understand unexplained variation in postnatal muscle traits are lacking. In a bovine model we studied effects of distinct maternal and paternal genomes, fetal sex, and non-genetic maternal effects on fetal myofibre characteristics and muscle mass. Data from 73 fetuses (Day153, 54% term) of four genetic groups with purebred and reciprocal cross Angus and Brahman genetics were analyzed using general linear models. Parental genomes explained the greatest proportion of variation in myofibre size of Musculus semitendinosus (80-96%) and in absolute and relative weights of M. supraspinatus, M. longissimus dorsi, M. quadriceps femoris and M. semimembranosus (82-89% and 56-93%, respectively).

Full Text Available Firms increasingly adopt cooperative strategies and form strategic alliances with foreign partners to be prosperous in entering to international market. Most of scholars have typically focused on generic, conceptual models for alliances partner selection, addressing only limited dimensions of the partner characteristics. This paper presents a new empirical framework that considering the effect of partner characteristics on export performance of alliances, in the case of short/mediumterm alliances and long-term ones. The study explores the effective partner characteristics for each type of alliances based on a sample of 540 alliances which rooted in East European region and also, have at least one Iranian partner. The findings stress the differences between varied partner characteristics in short/medium-term and long-term alliances. More specifically, results introduce a framework that addresses certain and specific partner characteristics to improve the export performance of alliances, due to the time frame of strategic alliances.

Full Text Available Irrespective of the avenue chosen for the retail of milling and bakery products, a key role in sales growth is the one played by promotion, information of the future customers as to the characteristics of the products, the execution and sale conditions. Such information process takes place by means of the promotional mix, consisting of a blend of advertising, sales promotion, public relations tools, trademarks, promotional events, and sales forces. The milling and baking industry uses, to certain extent, all the components of the promotional mix. Product promotion is central both to sales growth, as well as to educating, advising and informing consumers as to how they can select quality milling and bakery products.

(1) To assess the prevalence of rural primary care physician (PCP) bypass, a behavior in which residents travel farther than necessary to obtain health care, (2) To examine the role of community and non-health-care-related characteristics on bypass behavior, and (3) To analyze spatial bypass patterns to determine which rural communities are most affected by bypass. Data came from the Montana Health Matters survey, which gathered self-reported information from Montana residents on their health care utilization, satisfaction with health care services, and community and demographic characteristics. Logistic regression and spatial analysis were used to examine the probability and spatial patterns of bypass. Overall, 39% of respondents bypass local health care. Similar to previous studies, dissatisfaction with local health care was found to increase the likelihood of bypass. Dissatisfaction with local shopping also increases the likelihood of bypass, while the number of friends in a community, and commonality with community reduce the likelihood of bypass. Other significant factors associated with bypass include age, income, health, and living in a highly rural community or one with high commuting flows. Our results suggest that outshopping theory, in which patients bundle services and shopping for added convenience, extends to primary health care selection. This implies that rural health care selection is multifaceted, and that in addition to perceived satisfaction with local health care, the quality of local shopping and levels of community attachment also influence bypass behavior. © 2014 National Rural Health Association.

Community health service in China is designed to provide a convenient and affordable primary health service for the city residents, and to promote health equity. Based on data from a large national study of 35 cities across China, we examined the characteristics of the patients and the utilization of community health institutions (CHIs), and assessed the role of community health service in promoting equity in health service utilization for community residents. Multistage sampling method was applied to select 35 cities in China. Four CHIs were randomly chosen in every district of the 35 cities. A total of 88,482 visitors to the selected CHIs were investigated by using intercept survey method at the exit of the CHIs in 2008, 2009, 2010, and 2011. Descriptive analyses were used to analyze the main characteristics (gender, age, and income) of the CHI visitors, and the results were compared with that from the National Health Services Survey (NHSS, including CHIs and higher levels of hospitals). We also analyzed the service utilization and the satisfactions of the CHI visitors. The proportions of the children (2.4%) and the elderly (about 22.7%) were lower in our survey than those in NHSS (9.8% and 38.8% respectively). The proportion of the low-income group (26.4%) was apparently higher than that in NHSS (12.5%). The children group had the lowest satisfaction with the CHIs than other age groups. The satisfaction of the low-income visitors was slightly higher than that of the higher-income visitors. The utilization rate of public health services was low in CHIs. The CHIs in China appears to fulfill the public health target of uptake by vulnerable populations, and may play an important role in promoting equity in health service utilization. However, services for children and the elderly should be strengthened.

2012-01-01

Full Text Available Ce-promoted Ni-catalysts from hydrotalcites were obtained. The effect of calcination temperature on the chemical and physical properties of the catalysts was studied. Several techniques were used to determine the chemical and physical characteristics of oxides. The apparent activation energies of reduction were determined. Catalytic experiments at 48 L g-1h-1 without pre-reduction in CO2 reforming of methane were performed. The spinel-like phase in these oxides was only formed at 1000 ºC. The reduction of Ni2+ in the oxides was clearly affected by the calcination temperature which was correlated with catalytic performance. The catalyst calcined at 700 ºC showed the greatest activity.

Watanabe, Atsushi; Ebara, Shinji; Sagara, Akio; Hashizume, Hidetoshi

2013-01-01

A Flibe blanket has been proposed to be used in FFHR. Since Flibe has poor heat transfer performance, heat transfer promoter is required, and a sphere-packed pipe (SPP) has been proposed to enhance the heat transfer performance in the Flibe blanket. In this paper, the fluid flow and heat transfer characteristics in the SPP is evaluated numerically using a k–ε turbulent model for the flow field and an algebraic model for the thermal field. As a result, it was shown that bypass flows in the SPP play a significant role in heat transfer. Also it is thought that the turbulent energy can strongly affect heat transfer performance

Utility poles not affected by CCA decision

Energy Technology Data Exchange (ETDEWEB)

De Venzio, H. [Arch Wood Protection Canada, Mississauga, ON (Canada)

2002-08-01

A voluntary decision by industry to move non-industrial use of treated lumber products away from pressure-treated wood containing chromated copper arsenate (CCA) preservative was announced by the Environmental Protection Agency on February 12, 2002. Although new alternative wood preservatives would be used, this decision does not affect utility poles, which will continue to be sold and installed. The author provides a brief historical outline concerning the creation of CCA in 1933 and its subsequent uses. CCA has many advantages, including clean surface of the poles, ground line treatment that is not required thus eliminating the requirement to rotate the poles during extended storage periods. Conductivity is low, as is corrosivity without affecting the bending characteristics of the wood. The injection of a refined hydrocarbon oil emulsion in the outer layer of the pole after the treatment with CCA is offered by some pole producers to facilitate gaff penetration. Sawing, drilling and nailing are also made easier. Water repellents can be added to the treating solution to improve climbability, slowing down the absorption and release of moisture. Warranties, extending for 50-year periods, are offered by some companies against wood-destroying organisms. The North American Wood Pole Coalition (NAWPC) was formed in 1998 to promote the use of wood poles, and publishes brochures and technical bulletins to that effect.

Recognition of prokaryotic and eukaryotic promoters using convolutional deep learning neural networks

KAUST Repository

Umarov, Ramzan

2017-02-03

Accurate computational identification of promoters remains a challenge as these key DNA regulatory regions have variable structures composed of functional motifs that provide gene-specific initiation of transcription. In this paper we utilize Convolutional Neural Networks (CNN) to analyze sequence characteristics of prokaryotic and eukaryotic promoters and build their predictive models. We trained a similar CNN architecture on promoters of five distant organisms: human, mouse, plant (Arabidopsis), and two bacteria (Escherichia coli and Bacillus subtilis). We found that CNN trained on sigma70 subclass of Escherichia coli promoter gives an excellent classification of promoters and non-promoter sequences (Sn = 0.90, Sp = 0.96, CC = 0.84). The Bacillus subtilis promoters identification CNN model achieves Sn = 0.91, Sp = 0.95, and CC = 0.86. For human, mouse and Arabidopsis promoters we employed CNNs for identification of two well-known promoter classes (TATA and non-TATA promoters). CNN models nicely recognize these complex functional regions. For human promoters Sn/Sp/CC accuracy of prediction reached 0.95/0.98/0,90 on TATA and 0.90/0.98/0.89 for non-TATA promoter sequences, respectively. For Arabidopsis we observed Sn/Sp/CC 0.95/0.97/0.91 (TATA) and 0.94/0.94/0.86 (non-TATA) promoters. Thus, the developed CNN models, implemented in CNNProm program, demonstrated the ability of deep learning approach to grasp complex promoter sequence characteristics and achieve significantly higher accuracy compared to the previously developed promoter prediction programs. We also propose random substitution procedure to discover positionally conserved promoter functional elements. As the suggested approach does not require knowledge of any specific promoter features, it can be easily extended to identify promoters and other complex functional regions in sequences of many other and especially newly sequenced genomes. The CNNProm program is available to run at web server http://www.softberry.com.

promoter database we found that ~14% of the identified 'forward' promoters overlap with a promoter oriented in the opposite direction. In this article we combine a mathematical model with experimental analysis of synthetic regulatory regions to investigate interference of overlapping promoters. We find...... that promoter interference depends on the characteristics of overlapping promoters. The model predicts that promoter strength and interference can be regulated separately, which provides unique opportunities for regulation. Our experimental data suggest that in principle any DNA binding protein can be used......Optimal response to environmental stimuli often requires activation of certain genes and repression of others. Dual function regulatory proteins play a key role in the differential regulation of gene expression. While repression can be achieved by any DNA binding protein through steric occlusion...

[The effect of goal framing on the activation of affective representations].

Science.gov (United States)

Takehashi, Hiroki; Karasawa, Kaori

2007-10-01

Guided by regulatory focus theory, this study examined the effects of goal framing on the subjective experience of affect and the accessibility of affective representations. Study I examined lay persons' beliefs concerning the relationship between goal framing and certain kinds of affective experiences. The results indicated that a promotion focus was associated with happiness and disappointment, whereas a prevention focus was associated with relaxation and tension. Study 2 examined the effect of goal framing on the activation of affective representations, and found that a promotion focus activated both gain-related representations (happy and disappointment) and loss-related representations (relaxation and tension), whereas a prevention focus activated only loss-related representations. These results suggest that goal framing activates particular affective representations, and the activated affective representations may influence the interpretation of positive or negative experiences. The discussion considered the function of the activation of affective representations as a mediator between goal framing and its cognitive and behavioral consequences.

Gestational age is estimated by ultrasound using fetal size as a proxy for age, although variance in early growth affects reliability. The aim of this study was to identify characteristics associated with discrepancies between last menstrual period-based (EDD-LMP) and ultrasound-based (EDD-US) estimated delivery dates. We identified all singleton births (n = 1 201 679) recorded in the Swedish Medical Birth Register in 1995-2010, to assess the association between maternal/fetal characteristics and large negative and large positive discrepancies (EDD-LMP earlier than EDD-US and 10th percentile in the discrepancy distribution vs. EDD-LMP later than EDD-US and 90th percentile). Analyses were adjusted for age, parity, height, body mass index, smoking, and employment status. Women with a body mass index >40 kg/m 2 had the highest odds for large negative discrepancies (-9 to -20 days) [odds ratio (OR) 2.16, 95% CI 2.01-2.33]. Other factors associated with large negative discrepancies were: diabetes, young maternal age, multiparity, body mass index between 30 and 39.9 kg/m 2 or +1 SD), and unemployment. Several maternal and fetal characteristics were associated with discrepancies between dating methods. Systematic associations of discrepancies with maternal height, fetal sex, and partly obesity, may reflect an influence on the precision of the ultrasound estimate due to variance in early growth. © 2016 The Authors.

Developmental theories of borderline personality disorder (BPD) posit that transactions between child characteristics and adverse environments, especially those in the context of the parent-child relationship, shape and maintain symptoms of the disorder over time. However, very little empirical work has investigated the role of parenting and parent-child transactions that may predict BPD severity over time. We examined maternal and dyadic affective behaviors during a mother-adolescent conflict discussion task as predictors of the course of BPD severity scores across 3 years in a diverse, at-risk sample of girls (N = 74) oversampled for affective instability and their biological mothers. Adolescent girls completed a structured conflict discussion task with their mothers at age 16. Girls' self-reported BPD severity scores were assessed annually from ages 15 to 17. Mother-adolescent interactions were coded using a global rating system of maternal and dyadic affective behaviors. Results from multilevel linear mixed models indicated that positive maternal affective behavior (i.e., supportive/validating behavior, communication skills, autonomy-promoting behavior, and positive affect) and positive dyadic affective behaviors (i.e., satisfaction and positive escalation) were associated with decreases in girls' BPD severity scores over time. Dyadic negative escalation was associated with higher overall levels of BPD severity scores, but negative maternal affective behavior (i.e., negative affect, dominance, conflict, and denial) was not. These findings suggest that the mother-daughter context is an important protective factor in shaping the course of BPD severity scores during adolescence and may be valuable in assessment, intervention, and prevention efforts.

Full Text Available This cross-sectional research study explored differences in health-promoting behavior and resilience among three groups of chronic kidney disease patients (high-risk, early chronic kidney disease; early CKD and pre-end stage renal disease; pre-ESRD treated at the Nephrology outpatient clinic in northern Taiwan. A total of 150 CKD outpatients were interviewed using structured questionnaires including a CKD Health to Promote Lifestyle Scale, and resilience scale. We found that the pre-ESRD group had lower resilience than either high-risk or early CKD groups. Factors affecting pre-ESRD resilience were gender, occupational status, diabetes and health-promoting behaviors. Factors affecting resilience of the high-risk group included level of education and health-promoting behaviors while factors affecting resilience in the early CKD group involved whether they are employed and health promoting behaviors. A significant positive correlation was found between health promoting behavior and resilience in all study subjects. Multiple regression analysis found that factors which could effectively predict resilience in patients at high-risk for CKD were gender, whether the patient had a job, nutrition, self-actualization, and stress level, accounting for 69.7% of the variance. Therefore, nursing education should focus on health promotion advocacy throughout the life of not only patients but also their families.

To determine: (1) What research has been done on health promotion interventions for low-wage workers and (2) what factors are associated with effective low-wage workers' health promotion programs. This review includes articles from PubMed and PsychINFO published in or before July 2016. Study Inclusion/Exclusion Criteria: The search yielded 130 unique articles, 35 met the inclusion criteria: (1) being conducted in the United States, (2) including an intervention or empirical data around health promotion among adult low-wage workers, and (3) measuring changes in low-wage worker health. Central features of the selected studies were extracted, including the theoretical foundation; study design; health promotion intervention content and delivery format; intervention-targeted outcomes; sample characteristics; and work, occupational, and industry characteristics. Consistent with a scoping review, we used a descriptive, content analysis approach to analyze extracted data. All authors agreed upon emergent themes and 2 authors independently coded data extracted from each article. The results suggest that the research on low-wage workers' health promotion is limited, but increasing, and that low-wage workers have limited access to and utilization of worksite health promotion programs. Workplace health promotion programs could have a positive effect on low-wage workers, but more work is needed to understand how to expand access, what drives participation, and which delivery mechanisms are most effective.

Our objective was to determine use by avian species (e.g., piscivores, marsh birds, waterfowl, selected passerines) of 29 wetlands in areas with low (chemistry, basin characteristics, and avian use of different wetland types. Shallow, beaver (Castor canadensis)-created wetlands with the highest phosphorus levels and abundant and varied macrophyte assemblages supported greater densities of macroinvertebrates and numbers of duck broods (88.3% of all broods) in contrast to deep, glacial type wetlands with sparse vegetation and lower invertebrate densities that supported fewer broods (11.7%). Low pH may have affected some acid-intolerant invertebrate taxa (i.e., Ephemeroptera), but high mean numbers of Insecta per wetland were recorded from wetlands with a pH of 5.51. Other Classes and Orders of invertebrates were more abundant on wetlands with pH > 5.51. All years combined use of wetlands by broods was greater on wetlands with pH ≤ 5.51 (77.4%) in contract to wetlands with pH > 5.51 that supported 21.8% of the broods. High mean brood density was associated with mean number of Insecta per wetland. For lentic wetlands created by beaver, those habitats contained vegetative structure and nutrients necessary to provide cover to support invertebrate populations that are prey of omnivore and insectivore species. The fishless status of a few wetlands may have affected use by some waterfowl species and obligate piscivores.

To compare workforce characteristics and staff perceptions of safety, satisfaction, and stress between Green House (GH) and comparison nursing homes (CNHs). Primary data on staff perceptions of safety, stress, and satisfaction from 13 GHs and 8 comparison NHs in 11 states; secondary data from human resources records on workforce characteristics, turnover, and staffing from 01/01/2011-06/30/2012. Observational study. Workforce data were from human resources offices; staff perceptions were from surveys. Few significant differences were found between GH and CNHs. Exceptions were GH direct caregivers were older, provided twice the normalized hours per week budgeted per resident than CNAs in CNHs or Legacy NHs, and trended toward lower turnover. GH environment may promote staff longevity and does not negatively affect worker's stress, safety perceptions, or satisfaction. Larger studies are needed to confirm findings. © Health Research and Educational Trust.

2006-04-01

Full Text Available Using the two largest collections of Mus musculus and Homo sapiens transcription start sites (TSSs determined based on CAGE tags, ditags, full-length cDNAs, and other transcript data, we describe the compositional landscape surrounding TSSs with the aim of gaining better insight into the properties of mammalian promoters. We classified TSSs into four types based on compositional properties of regions immediately surrounding them. These properties highlighted distinctive features in the extended core promoters that helped us delineate boundaries of the transcription initiation domain space for both species. The TSS types were analyzed for associations with initiating dinucleotides, CpG islands, TATA boxes, and an extensive collection of statistically significant cis-elements in mouse and human. We found that different TSS types show preferences for different sets of initiating dinucleotides and cis-elements. Through Gene Ontology and eVOC categories and tissue expression libraries we linked TSS characteristics to expression. Moreover, we show a link of TSS characteristics to very specific genomic organization in an example of immune-response-related genes (GO:0006955. Our results shed light on the global properties of the two transcriptomes not revealed before and therefore provide the framework for better understanding of the transcriptional mechanisms in the two species, as well as a framework for development of new and more efficient promoter- and gene-finding tools.

Food and beverage price promotions may be potential targets for public health initiatives but have not been well documented. We assessed prevalence and patterns of price promotions for food and beverage products in a nationwide sample of food stores by store type, product package size, and product healthfulness. We also assessed associations of price promotions with community characteristics and product prices. In-store data collected in 2010-2012 from 8959 food stores in 468 communities spanning 46 U.S. states were used. Differences in the prevalence of price promotions were tested across stores types, product varieties, and product package sizes. Multivariable regression analyses examined associations of presence of price promotions with community racial/ethnic and socioeconomic characteristics and with product prices. The prevalence of price promotions across all 44 products sampled was, on average, 13.4% in supermarkets (ranging from 9.1% for fresh fruits and vegetables to 18.2% for sugar-sweetened beverages), 4.5% in grocery stores (ranging from 2.5% for milk to 6.6% for breads and cereals), and 2.6% in limited service stores (ranging from 1.2% for fresh fruits and vegetables to 4.1% for breads and cereals). No differences were observed by community characteristics. Less-healthy versus more-healthy product varieties and larger versus smaller product package sizes generally had a higher prevalence of price promotion, particularly in supermarkets. On average, in supermarkets, price promotions were associated with 15.2% lower prices. The observed patterns of price promotions warrant more attention in public health food environment research and intervention. Copyright © 2016 Elsevier Inc. All rights reserved.

Understanding of Factors that Enable Health Promoters in Implementing Health-Promoting Schools: A Systematic Review and Narrative Synthesis of Qualitative Evidence

Hung, Tommy Tsz Man; Chiang, Vico Chung Lim; Dawson, Angela; Lee, Regina Lai Tong

2014-01-01

Health-promoting schools have been regarded as an important initiative in promoting child and adolescent health in school settings using the whole-school approach. Quantitative research has proved its effectiveness in various school-based programmes. However, few qualitative studies have been conducted to investigate the strategies used by health promoters to implement such initiatives. In this study, the researchers conducted a systematic review and narrative synthesis of the qualitative literature to identify important enablers assisting the implementation of health-promoting schools from the perspectives of health promoters. Five enablers have been identified from the review: (a) Following a framework/guideline to implement health-promoting schools; (b) Obtaining committed support and contributions from the school staff, school board management, government authorities, health agencies and other stakeholders; (c) Adopting a multidisciplinary, collaborative approach to implementing HPS; (d) Establishing professional networks and relationships; and (e) Continuing training and education in school health promotion. This highlights the importance of developing school health policies that meet local health needs, and socio-cultural characteristics that can foster mutual understanding between the health and education sectors so as to foster health promotion in children and adolescents.

Health promotion: an ethical analysis.

Science.gov (United States)

Carter, Stacy M

2014-04-01

Thinking and practising ethically requires reasoning systematically about the right thing to do. Health promotion ethics - a form of applied ethics - includes analysis of health promotion practice and how this can be ethically justified. Existing frameworks can assist in such evaluation. These acknowledge the moral value of delivering benefits. But benefits need to be weighed against burdens, harms or wrongs, and these should be minimised: they include invading privacy, breaking confidentiality, restraining liberty, undermining self-determination or people's own values, or perpetuating injustice. Thinking about the ethics of health promotion also means recognising health promotion as a normative ideal: a vision of the good society. This ideal society values health, sees citizens as active and includes them in decisions that affect them, and makes the state responsible for providing all of its citizens, no matter how advantaged or disadvantaged, with the conditions and resources they need to be healthy. Ethicists writing about health promotion have focused on this relationship between the citizen and the state. Comparing existing frameworks, theories and the expressed values of practitioners themselves, we can see common patterns. All oppose pursuing an instrumental, individualistic, health-at-all-costs vision of health promotion. And all defend the moral significance of just processes: those that engage with citizens in a transparent, inclusive and open way. In recent years, some Australian governments have sought to delegitimise health promotion, defining it as extraneous to the role of the state. Good evidence is not enough to counter this trend, because it is founded in competing visions of a good society. For this reason, the most pressing agenda for health promotion ethics is to engage with communities, in a procedurally just way, about the role and responsibilities of the citizen and the state in promoting and maintaining good health.

2014-01-01

Given that lifestyleshave similar determinants and that school-based interventions are usually targeted at all the risks that affect adolescents, the objective of this systematic review was to summarize the characteristics and effects of school-based interventions acting on different behavioral domains of adolescent health promotion. The review process was conducted by two independent reviewers who searched PubMed, Scopus, PsycINFO, and ERIC databases for experimental or observational studies with at least two measures of results published from 2007 to 2011, given that the research information available doubles every 5 years. Methodological quality was assessed with a standardized tool. Information was extracted from 35 studies aiming to prevent risk behaviors and promote healthy nutrition, physical activity, and mental and holistic health. Activities were based on theoretical models and were classified into interactive lessons, peer mediation, environmental changes, parents' and community activities, and tailored messages by computer-assisted training or other resources, usually including multiple components. In some cases, we identified some moderate to large, short- and long-term effects on behavioral and intermediate variable. This exhaustive review found that well-implemented interventions can promote adolescent health. These findings are consistent with recent reviews. Implications for practice, public health, and research are discussed. Copyright © 2014 SESPAS. Published by Elsevier Espana. All rights reserved.

Full Text Available Background/Aims: The influence of the endoscopist on the polyp detection rate (PDR is underappreciated in clinical practice. Moreover, flat lesions or lesions of the proximal colon are more difficult to detect. Here, we evaluated the differences in the PDR and the characteristics of detected polyps according to the experience of the colonoscopist. Methods: We collected data on 2,549 patients who underwent screening colonoscopy performed by three fellows. The PDR was calculated according to the percentage of patients who had at least one polyp (method A and according to the percentage of detected lesions (method B. The primary outcome included the change in the PDR, and the secondary outcome included the change in the characteristics of the detected polyps with increasing experience of the colonoscopist. Results: No proportional correlation was found between the PDR and increasing experience in colonoscopy with method A; however, with method B, the PDR increased after 400 colonoscopies (p=0.0209. With method B, the detection rates of small polyps (<5 mm (p=0.0015 and polyps in proximal sites (p=0.0050 increased after 300 colonoscopies. Conclusions: Our study demonstrated that the quality of a colonoscopy, measured by using the PDR, may increase when performed by experienced fellows.

Promoting health or promoting pleasure? A contingency approach to the effect of informational and emotional appeals on food liking and consumption.

Science.gov (United States)

Dubé, L; Cantin, I

2000-12-01

Here, we suggest that the relative effectiveness of informational and emotional appeals in persuasive communications may depend on the dominant basis of attitude towards the focal item (affective or cognitive), and on the precise response being targeted (i.e. influencing affect-based food liking or cognitive-based consumption). Ninety-five participants (milk drinking adults) participated in an experiment in which they were presented with a persuasive communication promoting milk consumption. A mixed design combined as between-participants factors attitude bases (two: affective/cognitive) and persuasive appeals (two: informational/emotional) with, as a within-participants measure, types of effect (two: liking and consumption change intent). We also measured immediate feelings and thoughts responses to the communication. As expected, cognition-based attitudes were not sensitive to a match between persuasive appeals and types of effect. For affect-based attitudes, results confirmed the predicted superiority of a match between the affective and cognitive bases of the targeted responses and that of the persuasive appeal. Food liking was particularly sensitive to an emotional appeal while an informational appeal tended to be more influential on food consumption. The underlying mechanism of these effects and their implication for the practice of health promotion and food marketing are discussed. Copyright 2000 Academic Press.

This study examined and compared the physical health status, self-esteem, family support and health-promoting behaviours between aged living alone and the aged living with family. As the Korean population ages, the number of older people living alone is steadily rising. Previous studies have been conducted to define the factors affecting the health of older people. However, research studies focused on the impact of family support, which potentially affects the overall health of older people, have been rarely conducted. This was a comparative descriptive design. The survey included a set of four questionnaires. All measures were self-administered. In the data analysis, descriptive statistics were used to analyse the demographic characteristics. The Chi-square test and independent t-test were used to examine the differences between the aged living alone and the aged living with family. The physical health status (t=-40·85, pself-esteem (t=-26·75, pexercise (t=-15·86, pself-esteem and health-promoting behaviours than the aged living alone. Clinical practice should be focused on emotional support with family or society for Korean aged, especially the aged living alone. Also, the practice should be adjusted to encourage the health-promoting behaviour for them as well. © 2011 Blackwell Publishing Ltd.

Many factors contribute to the inappropriate use of medicines, including not only a lack of information but also inaccurate and misleading promotional information. This review examines how the promotion of pharmaceuticals directly affects the prescribing and use of medicines. We define promotion broadly as all actions taken directly by pharmaceutical companies with the aim of enhancing product sales. We look in greater detail at promotion techniques aimed at prescribers, such as sales representatives, pharmaceutical advertisements in medical journals and use of key opinion leaders, along with the quality of information provided and the effects thereof. We also discuss promotion to the public, through direct-to-consumer advertising, and its effects. Finally, we consider initiatives to regulate promotion that come from industry, government and nongovernmental organizations.

Well-being in the workplace is considered by many authors to be the outcome of the interaction between individual characteristics and those of the working and organizational environment. This study aims to understand the significance attributed to the concept of well-being in the workplace by employees, its influencing factors, and, among those, the role of individual psychological characteristics. The research was conducted on a sample of 72 employees using a qualitative approach based on focus groups and individual interviews. Data analysis was performed by a paper and pencil technique. The focus groups and interviews collected 628 statements, which were divided into three main areas: meaning of well-being in the workplace (248), any kind factors that affect well-being in the workplace (158), and individual characteristics that affect well-being in the workplace (222). The individual characteristics identified by the participants as capable of influencing well-being in the workplace include being positive, communication, management of difficulties and conflicts, socio-emotional skills, and values. The research was limited by the participants involved and by the sole use of the paper and pencil technique of data analysis. Results highlight that well-being in the workplace does not depend exclusively on external conditions in terms of the working and organizational environment within which the individual operates: so, it could be promoted not only from above, through actions by management, but also from below, influencing individual traits and behaviours. Results would be useful for developing training, workplace counselling, and organizational development activities aimed to support small groups, leaders, and other strategic players in the construction of the subsystems of well-being in the workplace.

One discusses the effect of selection of charged particles on conditions to maintain and the characteristics of a glow discharge with oscillating electrons. It is shown that there is a pressure dependent optimal level of ion selection when the energy efficiency of ion source reaches its maximum value. It is determined that departure of fast ionizing electrons affects negatively the discharge maintenance wile emission of slow plasma electrons may promote maintenance of a discharge high current shape. It is shown that high efficient electron emission without violation of a discharge stability may take place in a magnetic field due to different nature of spatial distributions of fast and slow particles in discharges with electron oscillation

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

2016-01-01

The purposes of the current study were to 1) test if the hinge position in the binding of skating skis has an effect on gross efficiency or cycle characteristics and 2) investigate whether hinge positioning affects synergistic components of the muscle activation in six lower leg muscles. Eleven male skiers performed three 4-min sessions at moderate intensity while cross-country ski-skating and using a klapskate binding. Three different positions were tested for the binding’s hinge, ranging from the front of the first distal phalange to the metatarsal-phalangeal joint. Gross efficiency and cycle characteristics were determined, and the electromyographic (EMG) signals of six lower limb muscles were collected. EMG signals were wavelet transformed, normalized, joined into a multi-dimensional vector, and submitted to a principle component analysis (PCA). Our results did not reveal any changes to gross efficiency or cycle characteristics when altering the hinge position. However, our EMG analysis found small but significant effects of hinge positioning on muscle coordinative patterns (P skating klapskates. Finally, the within-subject results of the EMG analysis suggested that in addition to the between-subject effects, further forms of muscle coordination patterns appear to be employed by some, but not all participants.

Full Text Available Introduction. Drug promotional advertisements (DPAs form a major marketing technique of pharmaceutical companies for promoting their products and disseminating ambiguous drug information which can affect prescribing pattern of physicians. Drug information includes product characteristics, various marketing claims with references in support to increase its credibility and authenticity. Material and Methods. An observational study was carried out on fifty printed drug advertisement brochures which were collected from different OPDs of Guru Nanak Dev Hospital attached to Government Medical College, Amritsar, India. These advertisements were analyzed and claims were categorized into true, false, exaggerated, vague, and controversial on criteria as reported by Rohraa et al. (2006.

Full Text Available This research used a questionnaire survey to explore the relationship between pupils’ attribution of their perceived mathematics performance and their affective attitudes towards mathematics learning as promoted by the different teaching methods they were exposed to in their mathematics classes. Both 5th and 8th graders attributed their success in learning mathematics to effort, although support from the teacher and support at home were also perceived as important factors in their success. The 5th graders and 8th graders overall gave effort-based attributions in the case of failure, while for 5th graders, ability was regarded as being as important as effort, in attributing failure in mathematics learning. Pupils who attributed their success in mathematics learning to effort, support at school and home, preferred teacher explanation and reading a textbook as learning strategies, while those attributing it to their ability preferred Individual work. Where pupils attributed success to luck, this seemed to have a negative effect on their affective attitudes towards mathematics learning as promoted by different teaching methods, while attributing failure to luck seemed to have positive effect. Attributing failure to poor teaching seemed to have a negative effect on their perception of teacher explanation. The relationships between pupil effort or ability based attributions of failure and their preference for different teaching methods were not clear. Adopting various teaching methods in mathematics classes would seem to support pupils who have different attribution styles.

This study investigates the level of satisfaction of Lebanese nurses in their job and the influence of their personal characteristics. Given the current difficulties experienced by Lebanese hospitals in recruiting and retaining a sufficient number of nurses, the need to understand the reasons of nurses' dissatisfaction became urgent. Moreover, satisfaction at work is essentially a personal experience also affected by cultural factors. Therefore, it was necessary to study the links between personal characteristics and nurses' dissatisfaction. The study included 421 registered nurses. A modified version of Measure of Job Satisfaction, developed by Taynor and Wade, was used to assess the effect of the personal characteristics, namely educational level, age, years of work experience, position, and marital and parental status, on 5 dimensions of satisfaction: personal satisfaction, workload, professional support, pay and prospect, and training. The findings suggest that personal characteristics have important influences on nurses' job perceptions. University graduate nurses reported more dissatisfaction with the quality of supervision and with respect and treatment they receive from their superiors. Nurses younger than 30 years and the technically trained were more dissatisfied with the available opportunities to attend continuing education courses. Results of staff nurses and unmarried nurses showed trends of more dissatisfaction than the married and nurses of higher positions. Moreover, the whole sample perceived that nursing provided a high level of personal satisfaction, but nurses were most dissatisfied with salary and lack of prospects for promotion. The results indicate the importance of personal characteristics on nurses' retention. Furthermore, intrinsic factors related to the nature and experience of nursing are more job satisfying than extrinsic factors.

2011-06-01

We documented the extent of point-of-sale (POS) lottery promotions in Ontario, Canada and the relationship between lottery promotions and store and city characteristics. This is the first quantitative study of POS lottery promotions. A total of 366 stores-independent and chain convenience stores, gas stations and grocery stores-were visited across 20 cities in Ontario. Data collectors unobtrusively observed the type of lottery promotions in each store and completed a data collection checklist. A lottery promotion index was created and hierarchical linear modeling (HLM) was conducted to examine the relationship between extent of lottery promotions and independent variables such as neighbourhood socioeconomic status and city prevalence of lottery ticket purchasing. POS lottery promotions were widespread across Ontario, with the highest level of promotion found in independent convenience stores. In the multivariable HLM model, none of the remaining independent variables remained statistically significant, except for store type. Lottery promotions are extensive at the POS in Ontario. These findings can help initiate discussions around the appropriateness and possible future regulation of this form of advertising.

How decision reversibility affects motivation.

2014-04-01

The present research examined how decision reversibility can affect motivation. On the basis of extant findings, it was suggested that 1 way it could affect motivation would be to strengthen different regulatory foci, with reversible decision making, compared to irreversible decision making, strengthening prevention-related motivation relatively more than promotion-related motivation. If so, then decision reversibility should have effects associated with the relative differences between prevention and promotion motivation. In 5 studies, we manipulated the reversibility of a decision and used different indicators of regulatory focus motivation to test these predictions. Specifically, Study 1 tested for differences in participants' preference for approach versus avoidance strategies toward a desired end state. In Study 2, we used speed and accuracy performance as indicators of participants' regulatory motivation, and in Study 3, we measured global versus local reaction time performance. In Study 4, we approached the research question in a different way, making use of the value-from-fit hypothesis (Higgins, 2000, 2002). We tested whether a fit between chronic regulatory focus and focus induced by the reversibility of the decision increased participants' subjective positive feelings about the decision outcome. Finally, in Study 5, we tested whether regulatory motivation, induced by decision reversibility, also influenced participants' preference in specific product features. The results generally support our hypothesis showing that, compared to irreversible decisions, reversible decisions strengthen a prevention focus more than a promotion focus. Implications for research on decision making are discussed.

Bialoskorski, Leticia S. S.; Westerink, Joyce H. D. M.; van den Broek, Egon L.

The progress in the field of affective computing enables the realization of affective consumer products, affective games, and affective art. This paper describes the affective interactive art system Mood Swings, which interprets and visualizes affect expressed by a person. Mood Swings is founded on the integration of a framework for affective movements and a color model. This enables Mood Swings to recognize affective movement characteristics as expressed by a person and display a color that matches the expressed emotion. With that, a unique interactive system is introduced, which can be considered as art, a game, or a combination of both.

2016-10-01

The O 6 -methylguanine-DNA methyltransferase (MGMT) protein removes O 6 -alkyl-guanine adducts from DNA. MGMT expression can thus alter the sensitivity of cells and tissues to environmental and chemotherapeutic alkylating agents. Previously, we defined the haplotype structure encompassing single nucleotide polymorphisms (SNPs) in the MGMT promoter/enhancer (P/E) region and found that haplotypes, rather than individual SNPs, alter MGMT promoter activity. The exact mechanism(s) by which these haplotypes exert their effect on MGMT promoter activity is currently unknown, but we noted that many of the SNPs comprising the MGMT P/E haplotypes are located within or in close proximity to putative transcription factor binding sites. Thus, these haplotypes could potentially affect transcription factor binding and, subsequently, alter MGMT promoter activity. In this study, we test the hypothesis that MGMT P/E haplotypes affect MGMT promoter activity by altering transcription factor (TF) binding to the P/E region. We used a promoter binding TF profiling array and a reporter assay to evaluate the effect of different P/E haplotypes on TF binding and MGMT expression, respectively. Our data revealed a significant difference in TF binding profiles between the different haplotypes evaluated. We identified TFs that consistently showed significant haplotype-dependent binding alterations (p ≤ 0.01) and revealed their role in regulating MGMT expression using siRNAs and a dual-luciferase reporter assay system. The data generated support our hypothesis that promoter haplotypes alter the binding of TFs to the MGMT P/E and, subsequently, affect their regulatory function on MGMT promoter activity and expression level.

McCann, Terence V; Clark, Eileen; Rowe, Kathy

2005-09-01

Despite the fact that nurses have a key role in health promotion, many continue to smoke at much the same rate as the general population. This paper investigates the influence of smoking status, gender, age, stage of education, and smoking duration on undergraduate nursing students' attitudes towards smoking health promotion. The study took place in one university's School of Nursing in Victoria, Australia. Respondents completed the Smoking and Health Promotion instrument. Researchers obtained ethics approval prior to commencing the study. Smoking status was the main factor that affected respondents' attitudes towards smoking health promotion, with age and education stage having a minor effect, and gender and smoking duration not significant. Nurses have an important role in modeling non-smoking behaviors for patients. There needs to be consistency between personal and professional beliefs for nurses to properly engage in smoking health promotion. The findings have implications for undergraduate nursing education curricula, nursing practice and research, and these are discussed.

Family characteristics and parents' and children's health behaviour are associated with public health nurses' concerns at children's health examinations.

The study aimed to establish whether family characteristics and the health behaviour and illnesses of parents and children are associated with public health nurses' (PHNs') concerns about children's physical health and psychosocial development in the context of health examinations. Factors affecting children's health and well-being should be identified as early as possible to provide children and families appropriate support. In 2007-2009, a cross-sectional study in Finland collected information about PHNs' concerns, children's health and well-being as well as the background factors affecting them during health examinations of preschool-age children and school-aged children (n = 4795). Associations between family characteristics, parents' and children's behaviour and diseases, and PHNs' concerns were assessed using logistic regression analysis. Overweight in children, the long-term illnesses of both children and parents, and parental smoking were the factors most strongly associated with PHNs' concerns about a child's physical health whereas non-nuclear family types, the father's low educational level and unemployment, the child's lack of sleep, and bullying were associated with concerns about the child's psychosocial development. The connections found demonstrate that health examinations should address factors that affect the whole family's well-being so as to comprehensively promote children's health, growth and development. © 2016 John Wiley & Sons Australia, Ltd.

To examine nurses' health-promoting lifestyle behaviors, describe their self-reported engagement in employee wellness program benefit options, and explore relationships between nurse demographic factors, health characteristics and lifestyle behaviors. Nurses adopting unhealthy lifestyle behaviors are at significantly higher risk for developing a number of chronic diseases and are at increased susceptibility to exhaustion, job dissatisfaction and turnover. Strengthening professional nurses' abilities to engage in healthy lifestyle behaviors could serve as a valuable tool in combating negative workplace stress, promote improved work-life balance and personal well-being, and help retain qualified health-care providers. In a 187-bed community hospital in the Washington D.C. metropolitan area, we conducted an IRB-approved exploratory descriptive study. We examined 127 nurses' demographic characteristics, self-reported employer wellness program use, and measured their healthy lifestyle behaviors using the 52-item Health-Promoting Lifestyle Profile-II (HPLP-II) survey instrument. Nurse demographic and HPLP-II scores were analyzed in SPSS v20.0. Inferential univariate statistical testing examined relationships between nurse demographic factors, health and job characteristics, and HPLP-II score outcomes. Nurses over 40years old were more likely to report participation in hospital wellness program options. Statistically significant age differences were identified in total HPLP-II score (p=0.005), and two subscale scores-spiritual growth (p=0.002) and interpersonal relations (p=0.000). Post-hoc testing identified nurse participants 40-49years old and ≥50years old experienced slightly lower total HPLP-II score, subscale scores in comparison to younger colleagues. Nurses ≥40years old may benefit from additional employer support and guidance to promote and maintain healthy lifestyles, personal well-being, and positive interpersonal relationships.

The objective of the present study was to evaluate the effect of carbon dioxide (CO2) enrichment on the main health-promoting compounds and organoleptic characteristics of tomato (Solanum lycopersicum) fruits grown in greenhouse. The contents of health-promoting compounds, including lycopene, β-carotene, and ascorbic acid, as well as the flavour, indicated by sugars, titrable acidity, and sugar/acid ratio, were markedly increased in CO2 enrichment fruits. Furthermore, CO2 enrichment significantly enhanced other organoleptic characteristics, including colour, firmness, aroma, and sensory attributes in tomato fruits. The results indicated that CO2 enrichment has potential in promoting the nutritional value and organoleptic characteristics of tomatoes. Copyright © 2013 Elsevier Ltd. All rights reserved.

Pesticides are considered one of the major contemporary stressors of honey bee health. In this study, the effects of short-term exposure to lambda-cyhalothrin on lifespan, learning, and memory-related characteristics of Apis mellifera were systematically examined. Short-term exposure to lambda-cyhalothrin in worker bees reduced lifespan, affected learning and memory performance, reduced the homing ability, and influenced the expression levels of two learning and memory-related genes of A. mellifera. This research identifies the nature of the sublethal effects of lambda-cyhalothrin on bees and the level of exposure that can be harmful to bee health. This new information will assist in establishing guidelines for the safe use of lambda-cyhalothrin in the field.

How Hinge Positioning in Cross-Country Ski Bindings Affect Exercise Efficiency, Cycle Characteristics and Muscle Coordination during Submaximal Roller Skiing.

Full Text Available The purposes of the current study were to 1 test if the hinge position in the binding of skating skis has an effect on gross efficiency or cycle characteristics and 2 investigate whether hinge positioning affects synergistic components of the muscle activation in six lower leg muscles. Eleven male skiers performed three 4-min sessions at moderate intensity while cross-country ski-skating and using a klapskate binding. Three different positions were tested for the binding's hinge, ranging from the front of the first distal phalange to the metatarsal-phalangeal joint. Gross efficiency and cycle characteristics were determined, and the electromyographic (EMG signals of six lower limb muscles were collected. EMG signals were wavelet transformed, normalized, joined into a multi-dimensional vector, and submitted to a principle component analysis (PCA. Our results did not reveal any changes to gross efficiency or cycle characteristics when altering the hinge position. However, our EMG analysis found small but significant effects of hinge positioning on muscle coordinative patterns (P < 0.05. The changed patterns in muscle activation are in alignment with previously described mechanisms that explain the effects of hinge positioning in speed-skating klapskates. Finally, the within-subject results of the EMG analysis suggested that in addition to the between-subject effects, further forms of muscle coordination patterns appear to be employed by some, but not all participants.

Nowadays, employees are big assets to an institution. Every employee has a different educational background, degree, work skill, attitude and ethic that affect the performance. An institution including government institution implements a promotion system in order to improve the performance of the employees. Pangandaran Tourism, Industry, Trade, and SME Department is one of government agency that implements a promotion system to discover employees who deserve to get promotion. However, there are some practical deficiencies in the promotion system, one of which is the subjectivity issue. This work proposed a classification model that could minimize the subjectivity issue in employee promotion system. This paper reported a classification employee based on their eligibility for promotion. The degree of membership was decided using Mamdani Fuzzy based on determinant factors of the performance of employees. In the evaluation phase, this model had an accuracy of 91.4%. It goes to show that this model may minimize the subjectivity issue in the promotion system, especially at Pangandaran Tourism, Industry, Trade, and SME Department.

Mola, Ernesto; De Bonis, Judith A; Giancane, Raffaele

2008-01-01

Efforts to improve the quality of healthcare for patients with chronic conditions have resulted in growing evidence supporting the inclusion of patient empowerment as a key ingredient of care. In 2002, WONCA Europe issued the European Definition of General Practice/Family Medicine, which is currently considered the point of reference for European health institutions and general medical practice. Patient empowerment does not appear among the 11 characteristics of the discipline. The aim of this study is to show that many characteristics of general practice are already oriented towards patient empowerment. Therefore, promoting patient empowerment and self-management should be included as a characteristic of the discipline. The following investigation was conducted: analysing the concept and approach to empowerment as applied to healthcare in the literature; examining whether aspects of empowerment are already part of general medical practice; and identifying reasons why the European definition of general practice/family medicine should contain empowerment as a characteristic of the discipline. General practice/family medicine is the most suitable setting for promoting patient empowerment, because many of its characteristics are already oriented towards encouraging it and because its widespread presence can ensure the generalization of empowerment promotion and self-management education to the totality of patients and communities. "Promoting patient empowerment and self-management" should be considered one of the essential characteristics of general practice/family medicine and should be included in its definition.

Toral, Natacha; Conti, Maria Aparecida; Slater, Betzabeth

2009-11-01

The aim of this study was to evaluate perceptions, barriers, and characteristics of teaching materials to promote healthy eating, as described by teenagers. Four focus groups were conducted with 25 adolescents, including questions on: perceptions regarding diet and motivations to change; concepts of (and barriers to) healthy eating; and characteristics needed for teaching materials to promote healthy eating. The teens were often undecided when attempting to classify a diet as healthy. They generally reported feeling insecure about making dietary changes, but showed adequate notions of healthy eating. The main barriers involved personal and social characteristics: temptation, food flavors, parental influence, and lack of time and options for healthy snacks at school. According to these teenagers, educational materials for promotion of healthy eating should emphasize the immediate benefits and emphasize high-impact messages on the health risks of unhealthy diet.

A genome-wide analysis of promoter-mediated phenotypic noise in Escherichia coli.

Directory of Open Access Journals (Sweden)

Olin K Silander

2012-01-01

Full Text Available Gene expression is subject to random perturbations that lead to fluctuations in the rate of protein production. As a consequence, for any given protein, genetically identical organisms living in a constant environment will contain different amounts of that particular protein, resulting in different phenotypes. This phenomenon is known as "phenotypic noise." In bacterial systems, previous studies have shown that, for specific genes, both transcriptional and translational processes affect phenotypic noise. Here, we focus on how the promoter regions of genes affect noise and ask whether levels of promoter-mediated noise are correlated with genes' functional attributes, using data for over 60% of all promoters in Escherichia coli. We find that essential genes and genes with a high degree of evolutionary conservation have promoters that confer low levels of noise. We also find that the level of noise cannot be attributed to the evolutionary time that different genes have spent in the genome of E. coli. In contrast to previous results in eukaryotes, we find no association between promoter-mediated noise and gene expression plasticity. These results are consistent with the hypothesis that, in bacteria, natural selection can act to reduce gene expression noise and that some of this noise is controlled through the sequence of the promoter region alone.

The effects of affective and cognitive empathy on adolescents' behavior and outcomes in conflicts with mothers.

The current study investigated whether manipulations of affective and cognitive empathy have differential effects on observed behavior and self-reported outcomes in adolescent-mother conflict discussions. We further examined how these situational empathy inductions interact with preexisting empathic dispositions. To promote ecological validity, we conducted home visits to study conflict discussions about real disagreements in adolescent-mother relationships. We explored the roles of sex, age, and maternal support and power as covariates and moderators. Results indicated that the affective empathy manipulation had no significant effects on behavior, although a trend in the hypothesized direction suggested that affective empathy might promote active problem solving. The cognitive empathy manipulation led to lower conflict escalation and promoted other-oriented listening for adolescents low in dispositional cognitive empathy. State-trait interactions indicated that the empathy manipulations had significant effects on self-reported outcomes for adolescents lower in dispositional empathic concern. For these adolescents, both manipulations promoted outcome satisfaction, but only the cognitive manipulation promoted perceived fairness. This suggests that cognitive empathy, in particular, allows adolescents to distance themselves from the emotional heat of a conflict and listen to mothers' point of view, leading to outcomes perceived as both satisfying and fair. These findings are relevant for interventions and clinicians because they demonstrate unique effects of promoting affective versus cognitive empathy. Because even these minimal manipulations promoted significant effects on observed behavior and self-reported outcomes, particularly for low-empathy adolescents, stronger structural interventions are likely to have marked benefits.

The food-rich environment in which we live makes the regulation of food choices a very complex phenomenon determined by many factors, as well as their interactions. Much evidence suggests that the sensory perception of food can be considered as a central factor affecting individual food choices. Despite this, the approaches used to study the various food aspects usually do not distinguish between different types of food. In the present study, a large and heterogeneous sample of 1149 participants aged 7-90 years was asked to judge food images that were labelled differently (i.e. Raw versus Cooked, Natural versus Transformed and Simple versus Complex) with respect to arousal, valence, typicality and familiarity. We observed that, across food dimensions (i.e., Raw versus Cooked, Natural versus Transformed and Simple versus Complex), arousal, valence and typicality judgments were principally affected by a subjective hunger level and gender (and their interaction) and, to a lesser extent, by age. As a whole, our findings suggest that the level of transformation (which includes cooking) and the complexity of a foodstuff could at least partially affect food processing, entailing that future research should also address these features. © 2018 The British Dietetic Association Ltd.

Functional analysis of the OCA-B promoter.

Stevens, S; Wang, L; Roeder, R G

2000-06-15

OCA-B was identified as a B cell-specific coactivator that functions with either Oct-1 or Oct-2 to mediate efficient cell type-specific transcription via the octamer site (ATGCAAAT) both in vivo and in vitro. Mice lacking OCA-B exhibit normal Ag-independent B cell maturation. In contrast, Ag-dependent functions, including production of secondary Ig isotypes and germinal center formation, are greatly affected. To better understand OCA-B expression and, ultimately, the defects observed in the OCA-B knockout mice, we have cloned the OCA-B promoter and examined its function in both transformed and primary B cells. We show here that the OCA-B promoter is developmentally regulated, with activity increasing throughout B cell differentiation. Through physical and functional assays, we have found an activating transcription factor/cAMP response element binding protein binding site (or cAMP response element) that is crucial for OCA-B promoter activity. Furthermore, we demonstrate that IL-4 and anti-CD40 induce both the OCA-B promoter and octamer-dependent promoters, thus implicating OCA-B in B cell signaling events in the nucleus.

Theoretical and clinical overview of affective temperaments in mood disorders

2015-07-01

Full Text Available Temperaments are imperturbable variations of personality, traits and ways of reacting to the environment that characterize individuals and remain constant throughout several different situations. Temperaments usually play a central role in determining emotional reactions, therefore several temperamental models have attempted to establish the potential relationship between temperaments and affective disorders. According to Hagop Akiskal, affective temperaments are subclinical and subaffective trait-like manifestations of affective disorders. Unlike several models of temperament which were exclusively developed theoretically in order to describe healthy human functioning, later extrapolated to capture the pathological domains of mental and behavioral features, the current model of affective temperaments was developed on classical traditions and mainly based on the observation of subjects with mood disorders and their healthy first degree relatives. There is accumulating evidence concerning the development of affective temperaments based on their adaptive evolutionary characteristics and genetic background, and normative data from large national studies on general and healthy samples indicate their universal characteristics. Studies in affective patient populations indicate that the relationship between affective temperaments and affective illness is more complex than a simple extrapolation from psychopathology and mental health, and affective temperaments may represent a latent state of the staging model, playing a pathoplastic role in mood disorders determining their evolution, clinical features, main characteristics and outcome. A large body of data on affective temperaments has been published during the last decade, deserving a critical analysis presented in this overview.

Characteristic differences between the promoters of intron-containing and intronless ribosomal protein genes in yeast

Directory of Open Access Journals (Sweden)

Vingron Martin

2008-10-01

Full Text Available Abstract Background More than two thirds of the highly expressed ribosomal protein (RP genes in Saccharomyces cerevisiae contain introns, which is in sharp contrast to the genome-wide five percent intron-containing genes. It is well established that introns carry regulatory sequences and that the transcription of RP genes is extensively and coordinately regulated. Here we test the hypotheses that introns are innately associated with heavily transcribed genes and that introns of RP genes contribute regulatory TF binding sequences. Moreover, we investigate whether promoter features are significantly different between intron-containing and intronless RP genes. Results We find that directly measured transcription rates tend to be lower for intron-containing compared to intronless RP genes. We do not observe any specifically enriched sequence motifs in the introns of RP genes other than those of the branch point and the two splice sites. Comparing the promoters of intron-containing and intronless RP genes, we detect differences in number and position of Rap1-binding and IFHL motifs. Moreover, the analysis of the length distribution and the folding free energies suggest that, at least in a sub-population of RP genes, the 5' untranslated sequences are optimized for regulatory function. Conclusion Our results argue against the direct involvement of introns in the regulation of transcription of highly expressed genes. Moreover, systematic differences in motif distributions suggest that RP transcription factors may act differently on intron-containing and intronless gene promoters. Thus, our findings contribute to the decoding of the RP promoter architecture and may fuel the discussion on the evolution of introns.

Parental emotional distress, particularly high maternal anxiety, is one of the most consistent predictors of child anxiety treatment outcome. In order to identify the cognitive, affective, and behavioral parenting characteristics of mothers of children with anxiety disorders who themselves have an anxiety disorder, we assessed the expectations, appraisals, and behaviors of 88 mothers of anxious children (44 mothers who were not anxious [NONANX] and 44 mothers with a current anxiety disorder [ANX]) when interacting with their 7-12-year-old children. There were no observed differences in anxiety and avoidance among children of ANX and NONANX mothers, but, compared with NONANX mothers, ANX mothers held more negative expectations, and they differed on observations of intrusiveness, expressed anxiety, warmth, and the quality of the relationship. Associations were moderated by the degree to which children expressed anxiety during the tasks. Maternal-reported negative emotions during the task significantly mediated the association between maternal anxiety status and the observed quality of the relationship. These findings suggest that maternal anxiety disorder is associated with reduced tolerance of children's negative emotions. This may interfere with the maintenance of a positive, supportive mother-child interaction under conditions of stress and, as such, this may impede optimum treatment outcomes. The findings identify potential cognitive, affective, and behavioral targets to improve treatment outcomes for children with anxiety disorders in the context of a current maternal anxiety disorder. 2013 APA, all rights reserved

Wortmeyer, Daniela Schmitz; Branco, Angela Uchoa

2016-09-01

In this article, our aim is to analyze institutional practices guided to promote the development of moral values within the context of military education of Brazilian Army combatant commissioned officers. From a cultural psychological approach, we discuss how social guidance within military culture operates at different levels of the affective-semiotic regulation of individuals, structuring complex experiences that give rise to hypergeneralized meaning fields regarding morality and military values. For this goal, we first introduce some theoretical topics related to values development, emphasizing their affective roots and role in the emergence, maintenance, amplification and attenuation of all relations between the person and the environment. Following a brief discussion on how social institutions try to promote changes in personal values, we provide an overview of values present in the military culture and socialization. Finally, the text focuses on the education of Brazilian Army combatant commissioned officers, describing how practices related to different levels of affective-semiotic experience combine in order to promote the internalization and externalization of specific moral values. We conclude suggesting issues for future investigation.

Health promotion in Swedish schools: school managers' views.

Science.gov (United States)

Persson, Louise; Haraldsson, Katarina

2017-04-01

Schools are recognized worldwide as settings for health promotion, and leadership has a bearing on schools' ability to be health promoting. School managers have a great influence on what is prioritized in school, which in turn affects students' school performance and health. There is lack of research into school managers' views on health promotion, and what they consider to be central to health promotion. The aim was therefore to examine school managers' views about what health promotion in schools include. An explorative design, qualitative content analysis, was performed. In-depth interviews were conducted with all 13 school managers of a middle-sized municipality in central Sweden. The analysis had both manifest and latent content and three categories: 'Organization and Collaboration', 'Optimize the arena' and 'Strengthen the individual', and 10 subcategories emerged. The theme, 'Opportunities for learning and a good life', describes the latent content of these categories. Taking into account the views of school managers are important because these views help form a more complete picture of how school managers work with health promotion and what is needed to enhance health promotion to improve students' opportunities for learning and a good life. The Ottawa Charter for Health promotion is thereby transformed into practice. © The Author (2013). Published by Oxford University Press. All rights reserved.

An unlikely suitor: Industrial Engineering in health promotion

Directory of Open Access Journals (Sweden)

Hattingh, T. S.

2013-05-01

Full Text Available Primary healthcare forms the foundation for transforming healthcare in South Africa. The primary healthcare system is based on five pillars, one of them being health promotion. The principles of health promotion advocate that promoting health and wellness within communities will reduce the burden of disease at both primary and higher levels of the healthcare system. The challenge in South Africa, is that the factors affecting communities often inhibit their ability to control their health. In addition, the health promotion function within clinics is underresourced: each health promoter serves impoverished communities of up to 50,000 people. This study aims to identify how industrial engineering principles can be applied to assess and improve the impact of health promotion on communities, and ultimately on the health care system as a whole. An industrial engineering approach has analysed five clinics within the Ekurhuleni Municipality in Gauteng. The results show a distinct lack of consistency between clinics. Common issues include a lack of standard processes, structures, measures, resources, and training to support health promotion. The problems identified are commonly analysed and addressed by industrial engineering in organisations, and industrial engineering could be a useful method for evaluating and improving the impact of health promotion on communities. Recommendations for improvement and further work were made based on the findings.

Toward a definition of affective instability.

Science.gov (United States)

Renaud, Suzane M; Zacchia, Camillo

2012-01-01

Affective instability is a psychophysiological symptom observed in some psychopathologies. It is a complex construct that encompasses (1) primary emotions, or affects, and secondary emotions, with each category having its own characteristics, amplitude, and duration, (2) rapid shifting from neutral or valenced affect to intense affect, and (3) dysfunctional modulation of emotions. Affective instability is often confused with mood lability, as in bipolar disorders, as well as with other terms. To clarify the concept, we searched databases for the term affective instability and read related articles on the topic. In this article we situate the term within the current affective nomenclature and human emotional experience, explore its psychophysiological features, and place it within the context of psychopathology. We explain why the term can potentially be confused with mood pathology and then define affective instability as an inherited temperamental trait modulated by developmental experience.

Localization and regulation of bacteriophage Mu promoters

International Nuclear Information System (INIS)

Stoddard, S.F.; Howe, M.M.

1989-01-01

Mu promoters active during the lytic cycle were located by isolating RNA at various times after induction of Mu prophages, radiolabeling it by capping in vitro, and hybridizing it to Mu DNA fragments on Southern blots. Signals were detected from four new promoters in addition to the previously characterized P e (early), P cM (repressor), and P mom (late) promoters. A major signal upstream of C was first observed at 12 min and intensified thereafter with RNA from cts and C amber but not replication-defective prophages; these characteristics indicate that this signal arises from a middle promoter, which we designate P m . With 20- and 40-min RNA, four additional major signals originated in the C-lys, F-G-I, N-P, and com-mom regions. These signals were missing with RNA from C amber and replication-defective prophages and therefore reflected the activity of late promoters, one of which we presume was P mom . Uninduced lysogens showed weak signals from five regions, one from the early regulatory region, three between genes B and lys, and one near the late genes K, L, and M. The first of these probably resulted from P cM activity; the others remain to be identified

Prasla, Munira; Prasla, Shameer Ali

2011-01-01

Schools have great potential in health promotion; however, this is often neglected area and fewer efforts are done in exploring status of school health promotion in Pakistan. This paper attempts to outline brief historical background of school health promotion in Pakistan; presents critical review of some international school health promotion perspectives; and finally explore opportunities and role of healthcare professionals in Pakistan's context. A critical review of peer-reviewed literature divided into two broad themes of international perspectives on school health promotion, and role of healthcare professionals. Results are presented in cross-cutting themes and in narrative style. School health promotion is very diverse phenomenon, situated in respective cultural contexts. Programmes pesent a range of characteristics from focusing on integrated approach to health education to behavioural changes; and from involving youngsters to policy advocacy. Like the programmes, role of healthcare professionals is also varied and dynamic and without clearly defining their role, development of effective health promotion programmes is difficult. School health promotion could be facilitated by appropriate trainings for healthcare professionals and evidence-based policy changes.

Precise regulation of gene expression dynamics favors complex promoter architectures.

Directory of Open Access Journals (Sweden)

Dirk Müller

2009-01-01

Full Text Available Promoters process signals through recruitment of transcription factors and RNA polymerase, and dynamic changes in promoter activity constitute a major noise source in gene expression. However, it is barely understood how complex promoter architectures determine key features of promoter dynamics. Here, we employ prototypical promoters of yeast ribosomal protein genes as well as simplified versions thereof to analyze the relations among promoter design, complexity, and function. These promoters combine the action of a general regulatory factor with that of specific transcription factors, a common motif of many eukaryotic promoters. By comprehensively analyzing stationary and dynamic promoter properties, this model-based approach enables us to pinpoint the structural characteristics underlying the observed behavior. Functional tradeoffs impose constraints on the promoter architecture of ribosomal protein genes. We find that a stable scaffold in the natural design results in low transcriptional noise and strong co-regulation of target genes in the presence of gene silencing. This configuration also exhibits superior shut-off properties, and it can serve as a tunable switch in living cells. Model validation with independent experimental data suggests that the models are sufficiently realistic. When combined, our results offer a mechanistic explanation for why specific factors are associated with low protein noise in vivo. Many of these findings hold for a broad range of model parameters and likely apply to other eukaryotic promoters of similar structure.

2009-12-01

Many adolescents do not meet public health recommendations for moderate-to-vigorous physical activity (MVPA). In studies of variables influencing adolescent MVPA, one that has been understudied is the affective response to exercise. We hypothesized that adolescents with a more positive affective response to acute exercise would be more active. Adolescents (N = 124; 46% male) completed two 30-min exercise tasks (above and below the ventilatory threshold [VT]), and wore ActiGraph accelerometers for 6.5 +/- 0.7 days. Affective valence was assessed before, during, and after each task. A more positive affective response during exercise below the VT was associated with greater participation in MVPA (p positive affective response to exercise will engage in more MVPA. To promote greater participation in MVPA among adolescents, programs should be designed to facilitate a positive affective experience during exercise.

2017-11-01

User characteristics should be considered when designing features for e-health or m-health applications, as the developed solution should aim to support this specific target group. This study explores the effect of user characteristics (personality, health state, stress/recovery state, leadership behavior) on the interest and likelihood of using an app for health promotion activities at the workplace. Leaders are a key factor for the success of workplace health promotion; therefore, the target group of this study are leaders. The data of 412 leaders were collected in an online study. Hierarchical multiple linear regression analyses were conducted for four outcome criteria ("personal health," "contacting," "leadership feedback" and "corporate key figures"). The findings showed that neuroticism, physical health and health-promoting leadership were important predictors for using an app for monitoring personal health and getting in social contact about health issues. The stress/recovery state was significantly related to the feature of getting in social contact.

Ren, Wenhui; Sun, Donghao; Wang, Chunmei; Li, Nan

2016-10-01

Objective To investigate the role of bromodomain containing 3 (Brd3) in LPS-triggered interleukin-6 (IL-6) production in macrophages and the underlying mechanism. Methods CRISPR-Cas9 technology was used to screen an RAW264.7 cell line with Brd3 knockout (Brd3 -/- ). The Brd3 -/- cells were used as an experimental group, and the parential cells expressing wide-type Brd3 as a control group. The IL-6 level in cell culture supernatant was detected by ELISA after 100 ng/mL LPS challenging. Effect of Brd3 knockout on the expression and activation of signal pathways involved in IL-6 expression, including the NF-κB and mitogen-activated protein kinase (MAPK) pathways were examined by Western blot analysis. Chromatin immunoprecipitation (ChIP) assay was used to evaluate the recruitment of acetylase CREB-binding protein (CBP) to IL6 gene promoter and the acetylation level of histone 3 within IL6 gene promoter. Results LPS treatment significantly downregulated Brd3 expression in mouse peritoneal macrophages. LPS-induced production of IL-6 was significantly inhibited in Brd3 -/- macrophages. The expressions and activation of signal molecules within NF-κB and MAPK pathways were barely affected. Brd3 knockout significantly decreased the recruitment of acetylase CBP to IL6 gene promoter, and the acetylation level of histone3 within IL6 gene promoter was also repressed. Conclusion Brd3 promotes LPS-triggered IL-6 production via promoting the recruitment of CBP to IL6 promoter and enhancing the acetylation level of histone 3 within IL6 promoter.

Competitive intransitivity promotes species coexistence.

Science.gov (United States)

Laird, Robert A; Schamp, Brandon S

2006-08-01

Using a spatially explicit cellular automaton model with local competition, we investigate the potential for varied levels of competitive intransitivity (i.e., nonhierarchical competition) to promote species coexistence. As predicted, on average, increased levels of intransitivity result in more sustained coexistence within simulated communities, although the outcome of competition also becomes increasingly unpredictable. Interestingly, even a moderate degree of intransitivity within a community can promote coexistence, in terms of both the length of time until the first competitive exclusion and the number of species remaining in the community after 500 simulated generations. These results suggest that modest levels of intransitivity in nature, such as those that are thought to be characteristic of plant communities, can contribute to coexistence and, therefore, community-scale biodiversity. We explore a potential connection between competitive intransitivity and neutral theory, whereby competitive intransitivity may represent an important mechanism for "ecological equivalence."

Snir, Avigal; Bar-Kalifa, Eran; Berenson, Kathy R; Downey, Geraldine; Rafaeli, Eshkol

2017-10-01

The current study's main goal was to examine whether affective instability is elevated among individuals suffering from avoidant personality disorder (APD) by comparing it to the affective instability found among individuals suffering from borderline personality disorder (BPD) as well that found among healthy controls. Adults (N = 152, aged 18-65 years) with BPD, APD, or no psychopathology participated in a 3-week computerized diary study. We examined temporal instability in negative affect using experience-sampling methods. Both within and between days, individuals with APD showed greater affective instability compared to the healthy control individuals, although less affective instability compared to individuals with BPD. The findings are in line with affective instability (or emotional lability) as a key dimension relevant across personality disorders. Additionally, they emphasize the need for research and clinical attention to affective characteristics (alongside the more readily recognized interpersonal characteristics) of APD.

Positive affect and cognitive control: approach-motivation intensity influences the balance between cognitive flexibility and stability.

Science.gov (United States)

Liu, Ya; Wang, Zhenhong

2014-05-01

In most prior research, positive affect has been consistently found to promote cognitive flexibility. However, the motivational dimensional model of affect assumes that the influence of positive affect on cognitive processes is modulated by approach-motivation intensity. In the present study, we extended the motivational dimensional model to the domain of cognitive control by examining the effect of low- versus high-approach-motivated positive affect on the balance between cognitive flexibility and stability in an attentional-set-shifting paradigm. Results showed that low-approach-motivated positive affect promoted cognitive flexibility but also caused higher distractibility, whereas high-approach-motivated positive affect enhanced perseverance but simultaneously reduced distractibility. These results suggest that the balance between cognitive flexibility and stability is modulated by the approach-motivation intensity of positive affective states. Therefore, it is essential to incorporate motivational intensity into studies on the influence of affect on cognitive control.

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.

Wang, Beiyun; Miao, Ya; Zhao, Zhe; Zhong, Yuan

2015-01-01

Diabetes and Alzheimer's disease are often associated with each other, whereas the relationship between two diseases is ill-defined. Although hyperglycemia during diabetes is a major cause of encephalopathy, diabetes may also cause chronic inflammatory complications including peripheral neuropathy. Hence the role and the characteristics of inflammatory macrophages in the development of diabetic encephalopathy need to be clarified. Diabetes were induced in mice by i.p. injection of streptozotocin (STZ). Two weeks after STZ injection and confirmation of development of diabetes, inflammatory macrophages were eliminated by i.p. injection of 20µg saporin-conjugated antibody against a macrophage surface marker CD11b (saporin-CD11b) twice per week, while a STZ-treated group received injection of rat IgG of same frequency as a control. The effects of macrophage depletion on brain degradation markers, brain malondialdehyde (MDA), catalase, superoxidase anion-positive cells and nitric oxide (NO) were measured. Saporin-CD11b significantly reduced inflammatory macrophages in brain, without affecting mouse blood glucose, serum insulin, glucose responses and beta cell mass. However, reduced brain macrophages significantly inhibited the STZ-induced decreases in brain MDA, catalase and superoxidase anion-positive cells, and the STZ-induced decreases in brain NO. Inflammatory macrophages may promote development of diabetic encephalopathy. © 2015 S. Karger AG, Basel.

Full Text Available To maximize the therapeutic efficacy of cardiac muscle constructs produced by stem cells and tissue engineering protocols, suitable scaffolds should be designed to recapitulate all the characteristics of native muscle and mimic the microenvironment encountered by cells in vivo. Moreover, so not to interfere with cardiac contractility, the scaffold should be deformable enough to withstand muscle contraction. Recently, it was suggested that the mechanical properties of scaffolds can interfere with stem/progenitor cell functions, and thus careful consideration is required when choosing polymers for targeted applications. In this study, cross-linked poly-ε-caprolactone membranes having similar chemical composition and controlled stiffness in a supra-physiological range were challenged with two sources of myoblasts to evaluate the suitability of substrates with different stiffness for cell adhesion, proliferation and differentiation. Furthermore, muscle-specific and non-related feeder layers were prepared on stiff surfaces to reveal the contribution of biological and mechanical cues to skeletal muscle progenitor differentiation. We demonstrated that substrate stiffness does affect myogenic differentiation, meaning that softer substrates can promote differentiation and that a muscle-specific feeder layer can improve the degree of maturation in skeletal muscle stem cells.

The "identifiable victim effect" refers to peoples' tendency to preferentially give to identified versus anonymous victims of misfortune, and has been proposed to partly depend on affect. By soliciting charitable donations from human subjects during behavioral and neural (i.e., functional magnetic resonance imaging) experiments, we sought to determine whether and how affect might promote the identifiable victim effect. Behaviorally, subjects gave more to orphans depicted by photographs versus silhouettes, and their shift in preferences was mediated by photograph-induced feelings of positive arousal, but not negative arousal. Neurally, while photographs versus silhouettes elicited activity in widespread circuits associated with facial and affective processing, only nucleus accumbens activity predicted and could statistically account for increased donations. Together, these findings suggest that presenting evaluable identifiable information can recruit positive arousal, which then promotes giving. We propose that affect elicited by identifiable stimuli can compel people to give more to strangers, even despite costs to the self.

Adenylate kinase (AK)-catalyzed phosphotransfer is essential in the maintenance of cellular energetic economy in cells of fully differentiated tissues with highly variable energy demand, such as muscle and brain. To investigate if AK isoenzymes have a comparable function in the energy-demand management of proliferating cells, AK1 and AK1beta were expressed in mouse neuroblastoma N2a cells and in human colon carcinoma SW480 cells. Glucose deprivation, galactose feeding, and metabolic inhibitor tests revealed a differential energy dependency for these two cell lines. N2a cells showed a faster proliferation rate and strongest coupling to mitochondrial activity, SW480 proliferation was more dependent on glycolysis. Despite these differences, ectopic expression of AK1 or AK1beta did not affect their growth characteristics under normal conditions. Also, no differential effects were seen under metabolic stress upon treatment with mitochondrial and glycolytic inhibitors in in vitro culture or in solid tumors grown in vivo. Although many intimate connections have been revealed between cell death and metabolism, our results suggest that AK1- or AK1beta-mediated high-energy phosphoryl transfer is not a modulating factor in the survival of tumor cells during episodes of metabolic crisis.

Risk tolerance is a source of variation in physician decision-making. This variation, if independent of clinical concerns, can result in mistaken utilization of health services. To address such problems, it will be helpful to identify nonclinical factors of risk tolerance, particularly those amendable to intervention-regulatory focus theory suggests such a factor. This study tested whether regulatory focus affects risk tolerance among primary care physicians. Twenty-seven primary care physicians were assigned to promotion-focused or prevention-focused manipulations and compared on the Risk Taking Attitudes in Medical Decision Making scale using a randomization test. Results provide evidence that physicians assigned to the promotion-focus manipulation adopted an attitude of greater risk tolerance than the physicians assigned to the prevention-focused manipulation (p = 0.01). The Cohen's d statistic was conventionally large at 0.92. Results imply that situational regulatory focus in primary care physicians affects risk tolerance and may thereby be a nonclinical source of practice variation. Results also provide marginal evidence that chronic regulatory focus is associated with risk tolerance (p = 0.05), but the mechanism remains unclear. Research and intervention targeting physician risk tolerance may benefit by considering situational regulatory focus as an explanatory factor.

Indoor nature exposure (INE): a health-promotion framework.

2015-03-01

Engaging in outdoor nature-based spaces has significant positive physiological and psychological health benefits. Although the integration of nature into indoor spaces is rarely considered a health-promoting tool, it may be an effective method for increasing nature engagement in a largely urbanized world. This paper presents an overview of indoor nature exposure (INE) by summarizing the current evidence of INE through the use of a scoping methodology. Results show that INE can be a health-promoting tool through the interaction of nature-based stimuli and individual characteristics (e.g. gender, age). Moreover, the results of the current literature need to be interpreted with consideration to methodological issues, such as the lack of participant characteristics, the issue of exposure realism and little qualitative data to highlight individual experiences. The scoping review process allowed for the summation of results and for a framework to be created in order to better understand how INE is facilitated. © The Author 2014.

Full Text Available This study examines the effect of manager’s characteristics on financial restatements among Malaysian public listed firms. Manager’s characteristics in this study refer to the Chief Executive Officer’s (CEO and Chairman of Audit Committee’s (CAC characteristics in an organisation. Using content analysis on 750 annual reports of 150 public listed firms in Bursa Malaysia, this study analyses the relationship between CEO and CAC's characteristics and financial restatements. The results show that only CEO’s characteristics in terms of educational and functional background significantly affect the financial restatements of the listed firms but the results are positive. The implication of this study is that more thorough recruitment of top managers is needed as their specific characteristics affect the financial restatement decisions. This study provides new data for the regulatory bodies which can be used further in setting rules and regulations in relation to managers for preventing aggressive financial restatements among the public listed firms.

Conclusion: This study concludes that CHWs are beneficial to health promotion and its various activities. They had a clear understanding of their roles and responsibilities, although they did not fully comprehend that what they were describing was, in fact, health promotion. When it came to advocacy, CHWs did not fully understand it, nor did they consider it as part of their roles, although they acknowledged its importance. Their role of increasing access to health care services by accompanying patients to the facilities has increased considerably because of changes in disease burden. This is affecting their ability to practise other health promotion activities which focus on disease prevention.

Protein Hydrolysates as Promoters of Non-Haem Iron Absorption

Science.gov (United States)

Li, Yanan; Jiang, Han; Huang, Guangrong

2017-01-01

Iron (Fe) is an essential micronutrient for human growth and health. Organic iron is an excellent iron supplement due to its bioavailability. Both amino acids and peptides improve iron bioavailability and absorption and are therefore valuable components of iron supplements. This review focuses on protein hydrolysates as potential promoters of iron absorption. The ability of protein hydrolysates to chelate iron is thought to be a key attribute for the promotion of iron absorption. Iron-chelatable protein hydrolysates are categorized by their absorption forms: amino acids, di- and tri-peptides and polypeptides. Their structural characteristics, including their size and amino acid sequence, as well as the presence of special amino acids, influence their iron chelation abilities and bioavailabilities. Protein hydrolysates promote iron absorption by keeping iron soluble, reducing ferric iron to ferrous iron, and promoting transport across cell membranes into the gut. We also discuss the use and relative merits of protein hydrolysates as iron supplements. PMID:28617327

Klamut, Marian Kazimierz

2002-01-01

The human mind is capable of creating an internal world--the psychic sphere--including the phenomena characteristic of human nature, such as selfconsciousness, conscious experiences, conceptual thinking, symbolic language, dreams, art, creation of culture, sense of values, interest in the distant past and care about the distant future. According to the exceptionally concordant opinions of the sages and scholars of the East and the West it is just within this internal world that human happiness dwells. Happiness is a state of the spirit which consists in: internal peace, satisfaction with one's life, the joy of life, benevolence and cordiality towards oneself and towards others; sensitivity to the beauty of nature, culture and art; harmonious co-existence with the surroundings. The achievement and experiencing of the states of thus understood happiness depend mainly on ourselves and, similarly to the project of health promotion, require knowledge, willingness and possibilities. Happiness Promotion denotes the commendation and popularizing of a certain definite way of thinking and acting--showing the road which leads to the frequent experiencing of happy moments.

Inflammatory Human Umbilical Cord-Derived Mesenchymal Stem Cells Promote Stem Cell-Like Characteristics of Cancer Cells in an IL-1β-Dependent Manner

Full Text Available To ensure the safety of clinical applications of MSCs, thorough understanding of their impacts on tumor initiation and progression is essential. Here, to further explore the complex dialog between MSCs and tumor cells, umbilical cord-derived mesenchymal stem cells (UC-MSCs were employed to be cocultured with either breast or ovarian cancer cells. Though having no obvious influence on proliferation or apoptosis, UC-MSCs exerted intense stem cell-like properties promoting effects on both cancer models. Cocultured cancer cells showed enriched side population, enhanced sphere formation ability, and upregulated pluripotency-associated stem cell markers. Human cytokine array and real-time PCR revealed a panel of MSC-derived prostemness cytokines CCL2, CXCL1, IL-8, and IL-6 which were induced upon coculturing. We further revealed IL-1β, a well-characterized proinflammatory cytokine, to be the inducer of these prostemness cytokines, which was generated from inflammatory UC-MSCs in an autocrine manner. Additionally, with introduction of IL-1RA (an IL-1 receptor antagonist into the coculturing system, the stem cell-like characteristics promoting effects of inflammatory UC-MSCs were partially blocked. Taken together, these findings suggest that transduced inflammatory MSCs work as a major source of IL-1β in tumor microenvironment and initiate the formation of prostemness niche via regulating their secretome in an IL-1β-dependent manner.

Shared decision-making (SDM) is poorly implemented in routine care, despite being promoted by health policies. No reviews have solely focused on an in-depth synthesis of the literature around organizational- and system-level characteristics (i.e., characteristics of healthcare organizations and of healthcare systems) that may affect SDM implementation. A synthesis would allow exploration of interventions to address these characteristics. The study aim was to compile a comprehensive overview of organizational- and system-level characteristics that are likely to influence the implementation of SDM, and to describe strategies to address those characteristics described in the literature. We conducted a scoping review using the Arksey and O'Malley framework. The search strategy included an electronic search and a secondary search including gray literature. We included publications reporting on projects that promoted implementation of SDM or other decision support interventions in routine healthcare. We screened titles and abstracts, and assessed full texts for eligibility. We used qualitative thematic analysis to identify organizational- and system-level characteristics. After screening 7745 records and assessing 354 full texts for eligibility, 48 publications on 32 distinct implementation projects were included. Most projects (N = 22) were conducted in the USA. Several organizational-level characteristics were described as influencing the implementation of SDM, including organizational leadership, culture, resources, and priorities, as well as teams and workflows. Described system-level characteristics included policies, clinical guidelines, incentives, culture, education, and licensing. We identified potential strategies to influence the described characteristics, e.g., examples how to facilitate distribution of decision aids in a healthcare institution. Although infrequently studied, organizational- and system-level characteristics appear to play a role in the

Magnetic resonance imaging (MRI) has an important impact in diagnosing primary angiitis of the central nervous system (PACNS). However, neuroradiologic findings may vary immensely, making an easy and definite diagnosis challenging. In this retrospective, single center study, we analyzed neuroradiologic findings of patients with PACNS diagnosed at our hospital between 2009 and 2014. Furthermore, we classified patients according to the affected vessel size and compared imaging characteristics between the subgroups. Thirty-three patients were included (mean age 43 [±15.3] years, 17 females) in this study. Patients with positive angiographic findings were classified as either medium or large vessel PACNS and presented more ischemic lesions (p effect. Twenty-five patients underwent brain biopsy. Patients with medium or large vessel PACNS were less likely to have positive biopsy results. It is essential to differentiate between small and medium/large vessel PACNS since results in MRI, digital subtraction angiography and brain biopsy may differ immensely. Since image quality of MR scanners improves gradually and brain biopsy may often be nonspecific or negative, our results emphasize the importance of MRI/MRA in the diagnosis process of PACNS.

Full Text Available Halobetasol propionate (HB is a potent synthetic corticosteroid used against inflammatory skin diseases, such as dermatitis, eczema, and psoriasis, among others. The aim of this study is to define how the presence of different skin penetration enhancers (nonane, menthone, limonene, azone, carene, decanol, linoleic acid and cetiol affects the penetration and retention in skin of HB. To determine drug penetration through skin, 5% of each promoter was used in an ex vivo system with human skin on Franz cells. The results showed that the highest permeation occurs in the presence of menthone, followed by nonane. Permeation parameters were determined. The in vivo test was assessed, and the formulation containing HB-menthone presented better anti-inflammatory efficacy. These results are useful to generate a specific treatment according to each patient’s needs, and the inflammatory characteristics of the disease.

Barriers and motivations affecting Information Systems usage by Hajj–Umrah religious tourism operators in Saudi Arabia

Hani Brdesee

2013-03-01

Full Text Available Hajj & Umrah religious tourism accounts for seven million visitors each year in Saudi Arabia. The government has recently taken initiatives to promote the use of Information Systems (IS in the religious tourism industry, encouraging firms to adopt IS innovations like e-commerce and enforcing the use of the Makha’a information system in Umrah for external pilgrims and the Yosr information system in Hajj for internal pilgrims. This study outlines the motivations and challenges that affect the utilisation of various IS services in the Saudi religious tourism industry through a qualitative analysis of the views and perceptions of senior executives and owners of travel firms. The findings suggest that while government initiatives and industry competitiveness were two positive factors promoting IS use, there are some major barriers preventing private firms from fully utilising the advantages of information systems. These include external factors such as lack of support from the IT industry and access to IT resources as well as internal factors within an organisation such as lack of commitment or the need for professional IT expertise. The study finds that relative advantage is a critical contributor to IS utilisation which depends on information systems characteristics.

In this study, we explored the reaction system CdO(s) + CO 2 (g) ⇄ CdCO 3 (s) as a model system for CO 2 capture agent in the intermediate temperature range of 300-400 °C. While pure CdO does not react with CO 2 at all up to 500 °C, CdO mixed with an appropriate amount of NaNO 3 (optimal molar ratio NaNO 3 /CdO = 0.14) greatly enhances the conversion of CdO into CdCO 3 up to ∼80% (5.68 mmol/g). These NaNO 3 -promoted CdO absorbents can undergo many cycles of absorption and desorption by temperature swing between 300 and 370 °C under a 100% CO 2 condition. Details of how NaNO 3 promotes the CO 2 absorption of CdO have been delineated through various techniques using thermogravimetry, coupled with X-ray diffraction and electron microscopy. On the basis of the observed data, we propose a mechanism of CO 2 absorption and desorption of NaNO 3 -promoted CdO. The absorption proceeds through a sequence of events of CO 2 adsorption on the CdO surface covered by NaNO 3 , dissolution of so-formed CdCO 3 , and precipitation of CdCO 3 particles in the NaNO 3 medium. The desorption occurs through the decomposition of CdCO 3 in the dissolved state in the NaNO 3 medium where CdO nanoparticles are formed dispersed in the NaNO 3 medium. The CdO nanoparticles are aggregated into micrometer-large particles with smooth surfaces and regular shapes.

2016-01-01

Background/Objectives: Consumption of fat-rich foods is associated with obesity and related alterations. However, there is a group of individuals, the metabolically obese normal-weight (MONW) subjects, who present normal body weight but have metabolic features characteristic of the obese status, including fat deposition in critical tissues such as liver, recognized as a major cause for the promotion of metabolic diseases. Our aim was to better understand metabolic alterations present in liver of MONW rats applying whole genome transcriptome analysis. Methods: Wistar rats were chronically fed a high-fat diet isocaloric relative to Control animals to avoid the hyperphagia and overweight and to mimic MONW features. Liver transcriptome analysis of both groups was performed. Results: Sustained intake of an isocaloric high-fat diet had a deep impact on the liver transcriptome, mainly affecting lipid metabolism. Although serum cholesterol levels were not affected, circulating triacylglycerols were lower, and metabolic adaptations at gene expression level indicated adaptation toward handling the increased fat content of the diet, an increased triacylglycerol and cholesterol deposition in liver of MONW rats was observed. Moreover, gene expression pointed to increased risk of liver injury. One of the top upregulated genes in this tissue was Krt23, a marker of hepatic disease in humans that was also increased at the protein level.Conclusion:Long-term intake of a high-fat diet, even in the absence of overweight/obesity or increase in classical blood risk biomarkers, promotes a molecular environment leading to hepatic lipid accumulation and increasing the risk of suffering from hepatic diseases.

Stress-activated protein kinase (SAPK) interacting protein 1 (SIN1) is an essential component of mTORC2. Previous studies have shown that SIN1 is a key regulator of Akt pathway which plays an important role in various pathological conditions including cancer. While its effects and mechanisms on the progression of NSCLC remain unknown. In this study, we report that SIN1 is able to promote the growth and migration of NSCLC cells both in vitro and in vivo. Overexpression of SIN1 promoted A549 and H1299 cells proliferation by both MTT and colony formation assays. Consistently, knockdown of SIN1 inhibited the proliferation of these cells. In transwell assay, overexpression of SIN1 increased the migration of A549 and H1299 cells, while SIN1 knockdown reduced their migration. In a tumor xenograft model, overexpression of SIN1 promoted tumor growth of A549 cells in vivo, while SIN1 knockdown suppresses the tumor growth. We also found a mechanistic link between SIN1 and H3K4me3, H3K4me3 is involved in SIN1 upregulation. Moreover, SIN1 can significantly promote the in vitro migration and invasion of NSCLC cells via induction epithelial mesenchymal transition (EMT) process, which subsequently leads to transcriptional downregulation of epithelial marker E-cadherin and upregulation of mesenchymal markers N-cadherin and Vimentin expression. Together, our results reveal that SIN1 plays an important role in NSCLC and SIN1 is a potential biomarker and a promising target in the treatment of NSCLC.

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.

Full Text Available To determine some socio-demographic characteristics and to evaluate daily life behaviors of the teachers who are working in Primary Schools in Edirne with Health Promotion Life Style Profile (HPLSP, was aimed in this study. This is a cross-sectional, descriptive study. A questionnaire which was prepared by the investigators and HPLSP was sent to all teachers working in 33 primary schools in Edirne. 410 teachers accepted to participate and completed the questionnaire. Data were evaluated by SPSS v 13.0. It was found that teachers participated in the study were generally at medium level at health promoting behaviors, and the highest mean score was nutrition and the lowest was exercise.

Full Text Available The Database Industry Promotion Act was proposed at the National Assembly plenary session on July 26, 2012 and since then it has been in the process of enactment in consultation with all the governmental departments concerned. The recent trend of economic globalization and smart device innovation suggests a new opportunity and challenges for all industries. The database industry is also facing a new phase in an era of smart innovation. Korea is in a moment of opportunity to take an innovative approach to promoting the database industry. Korea should set up a national policy to promote the database industry for citizens, government, and research institutions, as well as enterprises. Above all, the Database Industry Promotion Act could play a great role in promoting the social infrastructure to enhance the capacity of small and medium-sized enterprises. This article discusses the background of the development of the Database Industry Promotion Act and its legislative processes in order to clarify its legal characteristics, including the meaning of the act. In addition, this article explains individual items related to the overall structure of the Database Industry Promotion Act. Finally, this article reviews the economic effects of the database industry for now and the future.

Platelet [3H]imipramine binding in affective disorders: trait versus state characteristics

International Nuclear Information System (INIS)

Baron, M.; Barkai, A.; Gruen, R.; Peselow, E.; Fieve, R.R.; Quitkin, F.

1986-01-01

Platelet [3H]imipramine binding (Bmax) was determined in 67 patients with major affective illness (33 euthymic bipolar, 34 depressed unipolar) and 58 normal control subjects. Bipolar patients had significantly lower Bmax values than did control subjects. The mean Bmax in the unipolar patients was lower than in the control subjects, but the difference was not statistically significant. Dissociation constant (Kd) values did not distinguish patients in either category from control subjects. The significantly lower Bmax in euthymic bipolar patients and the apparent state independence of Bmax in some but not all unipolar patients suggest that platelet imipramine binding may be a trait marker in a subset of affective disorders

Affect and the computer game player: the effect of gender, personality, and game reinforcement structure on affective responses to computer game-play.

Science.gov (United States)

Chumbley, Justin; Griffiths, Mark

2006-06-01

Previous research on computer games has tended to concentrate on their more negative effects (e.g., addiction, increased aggression). This study departs from the traditional clinical and social learning explanations for these behavioral phenomena and examines the effect of personality, in-game reinforcement characteristics, gender, and skill on the emotional state of the game-player. Results demonstrated that in-game reinforcement characteristics and skill significantly effect a number of affective measures (most notably excitement and frustration). The implications of the impact of game-play on affect are discussed with reference to the concepts of "addiction" and "aggression."

Facial affect processing and depression susceptibility: cognitive biases and cognitive neuroscience.

Science.gov (United States)

Bistricky, Steven L; Ingram, Rick E; Atchley, Ruth Ann

2011-11-01

Facial affect processing is essential to social development and functioning and is particularly relevant to models of depression. Although cognitive and interpersonal theories have long described different pathways to depression, cognitive-interpersonal and evolutionary social risk models of depression focus on the interrelation of interpersonal experience, cognition, and social behavior. We therefore review the burgeoning depressive facial affect processing literature and examine its potential for integrating disciplines, theories, and research. In particular, we evaluate studies in which information processing or cognitive neuroscience paradigms were used to assess facial affect processing in depressed and depression-susceptible populations. Most studies have assessed and supported cognitive models. This research suggests that depressed and depression-vulnerable groups show abnormal facial affect interpretation, attention, and memory, although findings vary based on depression severity, comorbid anxiety, or length of time faces are viewed. Facial affect processing biases appear to correspond with distinct neural activity patterns and increased depressive emotion and thought. Biases typically emerge in depressed moods but are occasionally found in the absence of such moods. Indirect evidence suggests that childhood neglect might cultivate abnormal facial affect processing, which can impede social functioning in ways consistent with cognitive-interpersonal and interpersonal models. However, reviewed studies provide mixed support for the social risk model prediction that depressive states prompt cognitive hypervigilance to social threat information. We recommend prospective interdisciplinary research examining whether facial affect processing abnormalities promote-or are promoted by-depressogenic attachment experiences, negative thinking, and social dysfunction.

Full Text Available Plant growth promoting rhizobacteria (PGPR and mycorrhiza were evaluated on the growth (biomass and yield of Zea mays. In the present study, selective rhizospheric PGPR (Azotobacter chroococcum, Pseudomonas aeruginosa, Azospirillum brasilense and Streptomyces sp. and a combination of six strains of arbuscular mycorrhizal fungi (AMF (Acaulospora morrowae, Gigaspora margarita, Glomus constrictum, Glomus mossae, Glomus aggregatum and Scutellospora calospora were isolated and identified with standard methods and 16S rRNA sequence analysis. PGPR and AMF were checked for their growth-promoting behavior under specific treatment conditions. The 30-48-day-old treated plants in all combinations showed a significantly higher mass value. The average dry weight from the shoot was in a range from 41-52% as compared to the control. This increase also translated into a higher mass value of the roots. Overall, an 82% growth rate was observed in terms of height as the consequence of biomass production, specifically in the case of AMF + rhizobacteria combination. We report an efficient, sustainable and cost-effective biofertilizer for enhanced biomass of Z. mays, one of the staple food crops worldwide.

Alkyl-halogenide promoted ionic liquid catalysis of isobutane/butene-alkylation

Energy Technology Data Exchange (ETDEWEB)

Schilder, L.; Korth, W.; Jess, A. [Bayreuth Univ. (Germany). Dept. of Chemical Engineering

2011-07-01

The effect of two different types of promoters on the performance of Lewis-acidic chloroaluminate ionic liquid catalysts was studied for liquid liquid biphasic isobutane/2-butene alkylation. In particular, the activity and selectivity of such catalytic systems was investigated. Experimental results obtained from a batch reactor show, that tert-butyl halides increase the reaction rate significantly and shift the C8-selectivity towards the desired high-octane trimethylpentanes (TMPs). But, secondary reactions like oligomerization and cracking are not affected by the use of these promoters. (orig.)

Adolescents' aggressive and prosocial behaviors: links with social information processing, negative emotionality, moral affect, and moral cognition.

Science.gov (United States)

Laible, Deborah J; Murphy, Tia Panfile; Augustine, Mairin

2014-01-01

The goal of this study was to examine whether moral affect, moral cognition, negative emotionality, and attribution biases independently predicted adolescents' prosocial and aggressive behavior in adolescence. A total of 148 adolescents completed self-report measures of prosocial and aggressive behavior, moral affect, moral cognition, negative emotionality, and attribution biases. Although in general all 3 factors (emotional, moral, and social cognitive) were correlated with adolescent social behavior, the most consistent independent predictors of adolescent social behavior were moral affect and cognition. These findings have important implications for intervention and suggest that programs that promote adolescent perspective taking, moral reasoning, and moral affect are needed to reduce aggressive behavior and promote prosocial behavior.

Mental health promotion in comprehensive schools.

Onnela, A M; Vuokila-Oikkonen, P; Hurtig, T; Ebeling, H

2014-09-01

The purpose of this paper is to describe a participatory action research process on the development of a professional practice model of mental health nurses in mental health promotion in a comprehensive school environment in the city of Oulu, Finland. The developed model is a new method of mental health promotion for mental health nurses working in comprehensive schools. The professional practice model has been developed in workshops together with school staff, interest groups, parents and students. Information gathered from the workshops was analysed using action research methods. Mental health promotion interventions are delivered at three levels: universal, which is an intervention that affects the whole school or community; selective, which is an intervention focusing on a certain group of students; and indicated, which is an individually focused intervention. All interventions are delivered within the school setting, which is a universal setting for all school-aged children. The interventions share the goal of promoting mental health. The purposes of the interventions are enhancing protective factors, reducing risk factors relating to mental health problems and early identification of mental health problems as well as rapid delivery of support or referral to specialized services. The common effect of the interventions on all levels is the increase in the experience of positive mental health. © 2014 John Wiley & Sons Ltd.

To describe the physical activity (PA) promotion practices, beliefs, and barriers of Australasian oncology nurses and gain preliminary insight into how PA promotion practices may be affected by the demographics of the nurses.
. Cross-sectional survey.
. Australia and New Zealand.
. 119 registered oncology nurses.
. Self-reported online survey completed once per participant.
. Questions assessed the PA promotion beliefs (e.g., primary healthcare professionals responsible for PA promotion, treatment stage), PA benefits (e.g., primary benefits, evidence base), and PA promotion barriers of oncology nurses.
. Oncology nurses believed they were the major providers of PA advice to their patients. They promoted PA prior to, during, and post-treatment. The three most commonly cited benefits of PA for their patients were improved quality of life, mental health, and activities of daily living. Lack of time, lack of adequate support structures, and risk to patient were the most common barriers to PA promotion. Relatively few significant differences in the oncology nurses' PA promotion practices, beliefs, and barriers were observed based on hospital location or years of experience.
. Despite numerous barriers, Australasian oncology nurses wish to promote PA to their patients with cancer across multiple treatment stages because they believe PA is beneficial for their patients.
. Hospitals may need to better support oncology nurses in promoting PA to their patients and provide better referral pathways to exercise physiologists and physiotherapists.

Online Cooperative Promotion and Cost Sharing Policy under Supply Chain Competition

Directory of Open Access Journals (Sweden)

Erjiang E

2016-01-01

Full Text Available This paper studies online cooperative promotion and cost sharing decisions in competing supply chains. We consider a model of one B2C e-commerce platform and two supply chains each consisting of a supplier and an online retailer. The problem is studied using a multistage game. Firstly, the e-commerce platform carries out the cooperative promotion and sets the magnitude of markdown (the value of e-coupon. Secondly, each retailer and his supplier determine the fraction of promotional cost sharing when they have different bargaining power. Lastly, the retailers decide whether to participate in the cooperative promotion campaign. We show that the retailers are likely to participate in the promotion if consumers become more price-sensitive. However, it does not imply that the retailers can benefit from the price promotion; the promotion decision game resembles the classical prisoner’s dilemma game. The retailers and suppliers can benefit from the cooperative promotion by designing an appropriate cost sharing contract. For a supply chain, the bargaining power between supplier and retailer, consumer price sensitivity, and competition intensity affect the fraction of the promotional cost sharing. We also find that equilibrium value of e-coupon set by the e-commerce platform is not optimal for all the parties.

Interest Matters: The Importance of Promoting Interest in Education.

Science.gov (United States)

Harackiewicz, Judith M; Smith, Jessi L; Priniski, Stacy J

2016-10-01

Interest is a powerful motivational process that energizes learning, guides academic and career trajectories, and is essential to academic success. Interest is both a psychological state of attention and affect toward a particular object or topic, and an enduring predisposition to reengage over time. Integrating these two definitions, the four-phase model of interest development guides interventions that promote interest and capitalize on existing interests. Four interest-enhancing interventions seem useful: attention-getting settings, contexts evoking prior individual interest, problem-based learning, and enhancing utility value. Promoting interest can contribute to a more engaged, motivated, learning experience for students.

2017-09-01

Recent investigations highlighted the role of within-person pubertal changes for adolescents' behavior. Yet, little is known about effects on adolescents' daily affect, particularly regarding the hormonal changes underlying physical changes during puberty. In a study with 148 boys aged 10 to 20years, we tested whether within-person physical and hormonal changes over eight months predicted everyday affect fluctuations, measured with experience sampling. As expected, greater within-person changes in testosterone (but not in dehydroepiandrosterone) were associated with higher affect fluctuations in daily life. Additionally, greater physical changes predicted higher affect fluctuations for individuals in the beginning of puberty. The findings demonstrate the relevance of physical and hormonal changes in boys' affective (in)stability. Copyright © 2017 Elsevier Inc. All rights reserved.

Community pharmacists play an important role in the provision of health promotion services, and community pharmacies are considered as a potentially ideal site for cardiovascular health promotion. Information based on a systematic review of barriers to promoting cardiovascular health in community pharmacy is currently lacking. We have sought to identify the most important barriers to cardiovascular health promotion in the community pharmacy. We have systematically searched PubMed and International Pharmaceutical Abstracts for a period of 15 years from 1 April 1998 to 1 April 2013, contacted subject experts and hand-searched bibliographies. We have included peer-reviewed articles, with English abstracts in the analysis, if they reported community pharmacists' perceptions of the barriers to cardiovascular health promotion activities in a community pharmacy setting. Two reviewers have independently extracted study characteristics and data. We identified 24 studies that satisfy the eligibility criteria. The main barriers to cardiovascular health promotion in the community pharmacy included pharmacist-related factors; practice site factors; financial factors; legal factors; and patient-related factors. This review will help to provide reliable evidence for health promotion practitioners of the barriers to promoting cardiovascular health in the community pharmacy setting. This knowledge is valuable for the improvement of cardiovascular health promotion in this setting and guiding future research. © The Author 2015. Published by Oxford University Press.

Coffey, Laura; Gallagher, Pamela; Desmond, Deirdre; Ryall, Nicola

2014-05-01

This study examined the relationships between tenacious goal pursuit (TGP), flexible goal adjustment (FGA), and affective well-being in a sample of individuals with lower limb amputations. Cross-sectional, quantitative. Ninety-eight patients recently admitted to a primary prosthetic rehabilitation programme completed measures of TGP, FGA, positive affect, and negative affect. Hierarchical regression analyses revealed that TGP and FGA accounted for a significant proportion of the variance in both positive and negative affect, controlling for sociodemographic and clinical characteristics. TGP was significantly positively associated with positive affect, while FGA was significantly negatively associated with negative affect. Moderated regression analyses indicated that the beneficial effect of FGA on negative affect was strongest at high levels of amputation-related pain intensity and low levels of TGP. TGP and FGA appear to influence subjective well-being in different ways, with TGP promoting the experience of positive affect and FGA buffering against negative affect. TGP and FGA may prove useful in identifying individuals at risk of poor affective outcomes following lower limb amputation and represent important targets for intervention in this patient group. What is already known on this subject? The loss of a limb has a significant impact on several important life domains. Although some individuals experience emotional distress following amputation, the majority adjust well to their limb loss, with some achieving positive change or growth as a result of their experiences. Theories of self-regulation propose that disruptions in goal attainment have negative affective consequences. The physical, social, and psychological upheaval caused by limb loss is likely to threaten the attainment of valued goals, which may leave individuals vulnerable to negative psychosocial outcomes if they do not regulate their goals in response to these challenges. According to the dual

Full Text Available Postnatal myofibre characteristics and muscle mass are largely determined during fetal development and may be significantly affected by epigenetic parent-of-origin effects. However, data on such effects in prenatal muscle development that could help understand unexplained variation in postnatal muscle traits are lacking. In a bovine model we studied effects of distinct maternal and paternal genomes, fetal sex, and non-genetic maternal effects on fetal myofibre characteristics and muscle mass. Data from 73 fetuses (Day153, 54% term of four genetic groups with purebred and reciprocal cross Angus and Brahman genetics were analyzed using general linear models. Parental genomes explained the greatest proportion of variation in myofibre size of Musculus semitendinosus (80-96% and in absolute and relative weights of M. supraspinatus, M. longissimus dorsi, M. quadriceps femoris and M. semimembranosus (82-89% and 56-93%, respectively. Paternal genome in interaction with maternal genome (P<0.05 explained most genetic variation in cross sectional area (CSA of fast myotubes (68%, while maternal genome alone explained most genetic variation in CSA of fast myofibres (93%, P<0.01. Furthermore, maternal genome independently (M. semimembranosus, 88%, P<0.0001 or in combination (M. supraspinatus, 82%; M. longissimus dorsi, 93%; M. quadriceps femoris, 86% with nested maternal weight effect (5-6%, P<0.05, was the predominant source of variation for absolute muscle weights.

Background Leptospirosis is a zoonotic infectious disease that affects both humans and animals. The existing genetic tools for Leptospira spp. have improved our understanding of the biology of this spirochete as well as the interaction of pathogenic leptospires with the mammalian host. However, new tools are necessary to provide novel and useful information to the field. Methodology and Principal Findings A series of promoter-probe vectors carrying a reporter gene encoding green fluorescent protein (GFP) were constructed for use in L. biflexa. They were tested by constructing transcriptional fusions between the lipL41, Leptospiral Immunoglobulin-like A (ligA) and Sphingomielynase 2 (sph2) promoters from L. interrogans and the reporter gene. ligA and sph2 promoters were the most active, in comparison to the lipL41 promoter and the non-induced controls. The results obtained are in agreement with LigA expression from the L. interrogans Fiocruz L1-130 strain. Conclusions The novel vectors facilitated the in vitro evaluation of L. interrogans promoter activity under defined growth conditions which simulate the mammalian host environment. The fluorescence and rt-PCR data obtained closely reflected transcriptional regulation of the promoters, thus demonstrating the suitability of these vectors for assessing promoter activity in L. biflexa.

Full Text Available This study examines the mediating effect of motivational factors of pay and promotion on transformational leadership and organizational commitment relationship in Unilever Ghana using a quantitative, non-experimental, cross-sectional and analytical survey design study. The results of the study revealed significant positive relationship between transformational leadership style and affective commitment, continuance commitment, and normative commitment. However, the results of the study revealed no significant mediation of pay in the relationship between transformational leadership style and affective commitment, continuance commitment, and normative commitment. Additionally, no significant mediation of promotion was found in the relationship between transformational leadership and affective commitment, transformational leadership and continuance commitment, and transformational leadership and normative commitment. Managers’ adoption of transformational leadership behavior as a key strategy to get employees committed to the organizations will be of great significance because motivational factors such as pay and promotion do not mediate the transformational leadership and organizational commitment relationship. This is a maiden empirical research in Ghana where motivational factors are used as mediators in transformational leadership and organizational commitment relationship.

Amelogenin Affects Brushite Crystal Morphology and Promotes Its Phase Transformation to Monetite

Energy Technology Data Exchange (ETDEWEB)

Ren, Dongni; Ruan, Qichao; Tao, Jinhui; Lo, Jonathan; Nutt, Steven; Moradian-Oldak, Janet

2016-09-07

Amelogenin protein is involved in organized apatite crystallization during enamel formation. Brushite (CaHPO4·2H2O), which is one of the precursors for hydroxyapatite in in vitro mineralization, has been used for fabrication of biomaterials for hard tissue repair. In order to explore its potential application in biomimetic material synthesis, we studied the influence of amelogenin on brushite morphology and phase transformation to monetite. Our results show that amelogenin can adsorb onto surface of brushite, leading to the formation of layered structures on the (010) face. Amelogenin promoted the phase transformation of brushite into monetite (CaHPO4) in the dry state, presumably by interacting with crystalline water layers in brushite unit cell. Changes to the crystal morphology by amelogenin continued even after the phase transformation to monetite forming an organized nanotextured structure of nano-sticks resembling the bundle structure in enamel.

Exploring strategies to improve the health promotion orientation of Flemish sports clubs.

Meganck, Jeroen; Seghers, Jan; Scheerder, Jeroen

2017-08-01

Sports clubs are increasingly recognized as an innovative setting for health promotion, as exemplified by the health promoting sports club concept. This study aims to assess the health promotion orientation of both youth sports clubs (YSC) and adult sports clubs (ASC) in Flanders and to identify the motives and barriers as reported by their representatives as a basis for proposing intervention strategies to improve the health promotion orientation in sports clubs. A total of 253 Flemish sports clubs, consisting of 156 YSC and of 97 ASC, completed the online questionnaire, covering club characteristics (e.g. finances, human resources), perceived motives and barriers for health promotion and the health promoting sports club index. Even though YSC were more health promoting than ASC, the results indicated that all sports clubs could improve their health promotion orientation. The most consistent predictors of health promotion orientation are perceived motives index for YSC and perceived lack of resources for ASC. Based on these results, interventions to enhance the health promoting orientation need to tackle the lack of resources such as lack of expertise regarding health promotion. Interventions aimed specifically at YSC should emphasize the direct benefits, for example by demonstrating how health promotion helps clubs to improve the provision of high quality sports participation and by awarding a health promotion quality label. © The Author 2016.

Quality characteristics of edible linseed oil

Directory of Open Access Journals (Sweden)

M. NYKTER

2008-12-01

Full Text Available In this review the quality properties of linseed oil for food uses are discussed as well as factors affecting this quality. Linseed oil has a favourable fatty acid composition with a high linolenic acid content. Linseed oil contains nearly 60% á-linolenic acid, compared with 25% for plant oils generally. The content of linolenic acid and omega-3 fatty acids is reported to be high in linseed grown in northern latitudes. The composition of fatty acids, especially unsaturated fatty acids, reported in different studies varies considerably for linseed oil. This variation depends mainly on differences in the examined varieties and industrial processing treatments. The fatty acid composition leads also to some problems, rancidity probably being the most challenging. Some information has been published concerning oxidation and taste, whereas only a few studies have focused on colour or microbiological quality. Rancidity negatively affects the taste and odour of the oil. There are available a few studies on effects of storage on composition of linseed oil. In general, storage and heat promote auto-oxidation of fats, as well as decrease the amounts of tocopherols and vitamin E in linseed oil. Several methods are available to promote the quality of the oil, including agronomic methods and methods of breeding as well as chemical, biotechnological and microbiological methods. Time of harvesting and weather conditions affect the quality and yield of the oil.;

Full Text Available The article deals with the problems of democratization as a neocolonial practice. The author argues that the spread of democracy is similar in many respects to colonialism and civilizing mission as universal and even messianic phenomena. He notes that both of these phenomena, despite the similarity of their origin, have different "gender basis" (colonialism has characteristics of masculinity and civilizing mission - of femininity. The author reviewed the history of transforming the concepts of "colonialism" and "civilizing mission". Results parallels between the two phenomena are analyzed as a specific intellectual and public discourse in a particular era influenced the formation of both phenomena. Examples of national civilizing projects, their intellectual potential and influence on contemporary world politics are also considered. The echoes of colonialism and civilizing mission are visible in US and the EU doctrines of democracy promotion. Examining the evolution of approaches to democratization, the author finds the differences in strategic culture of the United States and the European Union: if the American establishment have a propensity to masculine practice of democracy promotion ("democratic enlargement", the project "Greater Middle East", etc., and European leadership prefers feminine practices. In terms of the post-colonial feminism, this approach does not give these actors any special benefits, as it offers the ineffective governing strategy of the local population, not taking into account, and often denying the specific cultural environment of democracy promotion, paying more attention to institutional characteristics (lack of certain civil rights and freedoms, lack of transparency in the work of public authorities, etc.. The author notes that the current strategy of democracy promotion, though being more complex, creates the effect of "double discrimination", when both the local people and local women (imposing image of "a free and

We determined how different hydroperiods affected leaf gas exchange characteristics of greenhouse-grown seedlings (2002) and saplings (2003) of the mangrove species Avicennia germinans (L.) Stearn., Laguncularia racemosa (L.) Gaertn. f., and Rhizophora mangle L. Hydroperiod treatments included no flooding (unflooded), intermittent flooding (intermittent), and permanent flooding (flooded). Plants in the intermittent treatment were measured under both flooded and drained states and compared separately. In the greenhouse study, plants of all species maintained different leaf areas in the contrasting hydroperiods during both years. Assimilation–light response curves indicated that the different hydroperiods had little effect on leaf gas exchange characteristics in either seedlings or saplings. However, short-term intermittent flooding for between 6 and 22 days caused a 20% reduction in maximum leaf-level carbon assimilation rate, a 51% lower light requirement to attain 50% of maximum assimilation, and a 38% higher demand from dark respiration. Although interspecific differences were evident for nearly all measured parameters in both years, there was little consistency in ranking of the interspecific responses. Species by hydroperiod interactions were significant only for sapling leaf area. In a field study, R. mangle saplings along the Shark River in the Everglades National Park either demonstrated no significant effect or slight enhancement of carbon assimilation and water-use efficiency while flooded. We obtained little evidence that contrasting hydroperiods affect leaf gas exchange characteristics of mangrove seedlings or saplings over long time intervals; however, intermittent flooding may cause short-term depressions in leaf gas exchange. The resilience of mangrove systems to flooding, as demonstrated in the permanently flooded treatments, will likely promote photosynthetic and morphological adjustment to slight hydroperiod shifts in many settings..

Sunderland, Naomi; Beekhuyzen, Jenine; Kendall, Elizabeth; Wolski, Malcom

There is a need to enhance the effectiveness and reach of complex health promotion initiatives by providing opportunities for diverse health promotion practitioners and others to interact in online settings. This paper reviews the existing literature on how to take health promotion communities and networks into online settings. A scoping review of relevant bodies of literature and empirical evidence was undertaken to provide an interpretive synthesis of existing knowledge on the topic. Sixteen studies were identified between 1986 and 2007. Relatively little research has been conducted on the process of taking existing offline communities and networks into online settings. However, more research has focused on offline (i.e. not mediated via computer networks); 'virtual' (purely online with no offline interpersonal contact); and 'multiplex' communities (i.e. those that interact across both online and offline settings). Results are summarised under three themes: characteristics of communities in online and offline settings; issues in moving offline communities online, and designing online communities to match community needs. Existing health promotion initiatives can benefit from online platforms that promote community building and knowledge sharing. Online e-health promotion settings and communities can successfully integrate with existing offline settings and communities to form 'multiplex' communities (i.e. communities that operate fluently across both online and offline settings).

HIV-related parental illness and death have a profound and lasting impact on a child's psychosocial wellbeing, potentially compromising the child's future. In response to a paucity of theoretical and conceptual discussions regarding the development of resilience among children affected by parental HIV, we proposed a conceptual framework of psychological resilience among children affected by HIV based on critical reviews of the existing theoretical and empirical literature. Three interactive social ecological factors were proposed to promote the resilience processes and attenuate the negative impact of parental HIV on children's psychological development. Internal assets, such as cognitive capacity, motivation to adapt, coping skills, religion/spirituality, and personality, promote resilience processes. Family resources and community resources are two critical contextual factors that facilitate resilience process. Family resources contain smooth transition, functional caregivers, attachment relationship, parenting discipline. Community resources contain teacher support, peer support, adult mentors, and effective school. The implications of the conceptual framework for future research and interventions among children affected by parental HIV were discussed.

The genomes of three plants, Arabidopsis (Arabidopsis thaliana), rice (Oryza sativa), and soybean (Glycine max), have been sequenced, and their many genes and promoters have been predicted. In Arabidopsis, cis-acting promoter elements involved in cold- and dehydration-responsive gene expression have been extensively analysed; however, the characteristics of such cis-acting promoter sequences in cold- and dehydration-inducible genes of rice and soybean remain to be clarified. In this study, we performed microarray analyses using the three species, and compared characteristics of identified cold- and dehydration-inducible genes. Transcription profiles of the cold- and dehydration-responsive genes were similar among these three species, showing representative upregulated (dehydrin/LEA) and downregulated (photosynthesis-related) genes. All (46 = 4096) hexamer sequences in the promoters of the three species were investigated, revealing the frequency of conserved sequences in cold- and dehydration-inducible promoters. A core sequence of the abscisic acid-responsive element (ABRE) was the most conserved in dehydration-inducible promoters of all three species, suggesting that transcriptional regulation for dehydration-inducible genes is similar among these three species, with the ABRE-dependent transcriptional pathway. In contrast, for cold-inducible promoters, the conserved hexamer sequences were diversified among these three species, suggesting the existence of diverse transcriptional regulatory pathways for cold-inducible genes among the species.

The aim of this study was to evaluate the methylation status of the promoter region of MLH1 gene in colorectal cancer (CRC) and its precursor lesions as well as elucidate its association with various clinicopathological characteristics among Iranian population. Epigenetic silencing of mismatch repair genes, such as MLH1 , by methylation of CpG islands of their promoter region has been proved to be an important mechanism in colorectal carcinogenesis. Fifty colorectal cancer and polyp tissue samples including 13 Primary colorectal tumor and 37 Adenoma polyp samples were enrolled in this study. Methylation-specific polymerase chain reaction (MSP) was performed to find the frequency of MLH1 Promoter Methylation. Promoter methylation of MLH1 gene was detected in 5 out of 13 tumor tissues and 4 out of 37 adenoma polyp. The frequency of MLH1 methylation in tumor samples was significantly higher compared to that in polyp tissues (P= 0.026). No significant association was observed between MLH1 promoter methylation and clinicopathological characteristics of the patients. The frequency of  MLH1  promoter methylation in CRC and colon polyp was 18%. Our findings indicated that methylation of MLH1 promoter region alone cannot be considered as a biomarker for early detection of CRC.

Tsunami sediments and their grain size characteristics

Characteristics of tsunami deposits are very complex as the deposition by tsunami is very complex processes. The grain size characteristics of tsunami deposits are simply generalized no matter the local condition in which the deposition took place. The general characteristics are fining upward and landward, poor sorting, and the grain size distribution is not unimodal. Here I review the grain size characteristics of tsunami deposit in various environments: swale, coastal marsh and lagoon/lake. Review results show that although there are similar characters in some environments and cases, but in detail the characteristics in each environment can be distinguished; therefore, the tsunami deposit in each environment has its own characteristic. The local geological and geomorphological condition of the environment may greatly affect the grain size characteristics.

Myostatin is a negative regulator of myogenesis and has been suggested to be an important factor in the development of muscle wasting during viral infection. The objective of this study was to characterize the main regulatory element of the grouper myostatin promoter and to study changes in promoter activity due to viral stimulation. In vitro and in vivo experiments indicated that the E-box E6 is a positive cis-and trans-regulation motif, and an essential binding site for MyoD. In contrast, the E-box E5 is a dominant negative cis-regulatory. The characteristics of grouper myostatin promoter are similar in regulation of muscle growth to that of other species, but mainly through specific regulatory elements. According to these results, we conducted a study to investigate the effect of viral infection on myostatin promoter activity and its regulation. The nervous necrosis virus (NNV) treatment significantly induced myostatin promoter activity. The present study is the first report describing that specific myostatin motifs regulate promoter activity and response to viral infection.

Carcinogenicity/tumour promotion by NDL PCB

2004-09-15

Polychlorinated biphenyls (PCBs) belong to the group of persistent environmental pollutants exhibiting neurotoxic, teratogenic and tumour-promoting effects in experimental animal models. PCB congeners can be divided into 'dioxinlike' and 'non-dioxinlike' congeners on the basis of their ability to act as aryl hydrocarbon receptor (AhR) agonists. Like the most toxic dioxin congener 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) 'dioxinlike' PCBs bind to the AhR and show characteristic effects on the expression of AhR-regulated genes including the induction of cytochrome P450 (CYP) 1A1. On the other hand, 'non-dioxinlike' PCB congeners have a lower or no binding affinity to the AhR, but exhibit a 'phenobarbital-type' induction of CYP 2B1/2 activity. A carcinogenic potential of PCBs has been demonstrated with technical mixtures such as Aroclors or Clophens. In these studies the liver and the thyroid gland were found to be the principal target organs of PCB-mediated carcinogenesis in rodents. No studies have been published, however, on the carcinogenicity of individual congeners. In two-stage initiation-promotion protocols in rats, both technical mixtures and individual 'dioxinlike' and 'non-dioxinlike' congeners were reported to act as liver tumour promoters.

Online social networking sites-a novel setting for health promotion?

Loss, Julika; Lindacher, Verena; Curbach, Janina

2014-03-01

Among adolescents, online social networking sites (SNS) such as Facebook are popular platforms for social interaction and may therefore be considered as 'novel settings' that could be exploited for health promotion. In this article, we examine the relevant definitions in health promotion and literature in order to analyze whether key characteristics of 'settings for health promotion' and the socio-ecological settings approach can be transferred to SNS. As many of our daily activities have shifted to cyberspace, we argue that online social interaction may gain more importance than geographic closeness for defining a 'setting'. While exposition to positive references to risk behavior by peers may render the SNS environment detrimental to health, SNS may allow people to create their own content and therefore foster participation. However, those health promotion projects delivered on SNS up until today solely relied on health education directed at end users. It remains unclear how health promotion on SNS can meet other requirements of the settings approach (e.g. building partnerships, changing the environment). As yet, one should be cautious in terming SNS a 'setting'. Copyright © 2013 Elsevier Ltd. All rights reserved.

Prohibition of antibiotic growth promoters has affected the genomic profiles of Lactobacillus salivarius inhabiting the swine intestine.

Jun-Yeong Lee

Full Text Available After the introduction of a ban on the use of antibiotic growth promoters (AGPs for livestock, the feeding environment, including the composition of animal intestinal microbiota, has changed rapidly. We hypothesized that the microbial genomes have also been affected by this legal prohibition, and investigated an important member of the swine gut microbiota, Lactobacillus salivarius, with a pan-genomic approach. Here, we isolated 21 L. salivarius strains composed of 6 strains isolated before the AGP prohibition (SBPs and 15 strains isolated after the AGP prohibition (SAPs at an interval of a decade, and the draft genomes were generated de novo. Several genomic differences between SBPs and SAPs were identified, although the number and function of antibiotic resistance genes were not different. SBPs showed larger genome size and a higher number of orthologs, as well as lower genetic diversity, than SAPs. SBPs had genes associated with the utilization of L-rhamnose and D-tagatose for energy production. Because these sugars are also used in exopolysaccharide (EPS synthesis, we tried to identify differences in biofilm formation-associated genes. The genes for the production of EPSs and extracellular proteins were different in terms of amino acid sequences. Indeed, SAPs formed dense biofilm and survived better than SBPs in the swine intestinal environment. These results suggest that SAPs have evolved and adapted to protect themselves from new selection pressure of the swine intestinal microenvironment by forming dense biofilms, adopting a distinct antibiotic resistance strategy. This finding is particularly important to understand the evolutionary changes in host-microbe interaction and provide detailed insight for the development of effective probiotics for livestock.

RNAs, PROMPTs are largely nuclear and rapidly turned over by the RNA exosome. PROMPT-transcribing DNA is occupied by RNA polymerase II (RNAPII) complexes with serine 2 phosphorylated C-terminal domains (CTDs), mimicking that of the associated genic region. Thus, the inefficient elongation capacity of PROMPT...... transcription cannot solely be assigned to poor CTD phosphorylation. Conditions that reduce gene transcription increase RNAPII occupancy of the upstream PROMPT region, suggesting that they reside in a common transcription compartment. Surprisingly, gene promoters that are actively transcribed by RNAPI...

Exploring health promotion practitioners' experiences of moral distress in Canada and Australia.

Sunderland, Naomi; Harris, Paul; Johnstone, Kylie; Del Fabbro, Letitia; Kendall, Elizabeth

2015-03-01

This article introduces moral distress - the experience of painful feelings due to institutional constraints on personal moral action - as a significant issue for the international health promotion workforce. Our exploratory study of practitioners' experiences of health promotion in Australia and Canada during 2009-2010 indicated that practitioners who work in upstream policy- and systems-level health promotion are affected by experiences of moral distress. Health promotion practitioners at all levels of the health promotion continuum also described themselves as being engaged in a minority practice within a larger dominant system that does not always value health promotion. We argue that health promotion practitioners are vulnerable to moral distress due to the values-driven and political nature of the practice, the emphasis on systems change and the inherent complexity and diversity of the practice. This vulnerability to moral distress poses significant challenges to both workers and organisations and the communities they seek to benefit. We propose that further research should be undertaken to fully identify the causes and symptoms of moral distress in health promotion. Extensive existing research on moral distress in nursing provides ample resources to conduct such research. © The Author(s) 2014.

Promoter DNA hypermethylation and gene repression in undifferentiated Arabidopsis cells.

Directory of Open Access Journals (Sweden)

María Berdasco

Full Text Available Maintaining and acquiring the pluripotent cell state in plants is critical to tissue regeneration and vegetative multiplication. Histone-based epigenetic mechanisms are important for regulating this undifferentiated state. Here we report the use of genetic and pharmacological experimental approaches to show that Arabidopsis cell suspensions and calluses specifically repress some genes as a result of promoter DNA hypermethylation. We found that promoters of the MAPK12, GSTU10 and BXL1 genes become hypermethylated in callus cells and that hypermethylation also affects the TTG1, GSTF5, SUVH8, fimbrin and CCD7 genes in cell suspensions. Promoter hypermethylation in undifferentiated cells was associated with histone hypoacetylation and primarily occurred at CpG sites. Accordingly, we found that the process specifically depends on MET1 and DRM2 methyltransferases, as demonstrated with DNA methyltransferase mutants. Our results suggest that promoter DNA methylation may be another important epigenetic mechanism for the establishment and/or maintenance of the undifferentiated state in plant cells.

The normative power of food promotions: Australian children's attachments to unhealthy food brands.

Science.gov (United States)

Kelly, Bridget; Freeman, Becky; King, Lesley; Chapman, Kathy; Baur, Louise A; Gill, Tim

2016-11-01

The formation of food brand associations and attachment is fundamental to brand preferences, which influence purchases and consumption. Food promotions operate through a cascade of links, from brand recognition, to affect, and on to consumption. Frequent exposures to product promotions may establish social norms for products, reinforcing brand affect. These pathways signify potential mechanisms for how children's exposure to unhealthy food promotions can contribute to poor diets. The present study explored children's brand associations and attachments for major food brands. A cross-sectional online survey was conducted. Fourteen study brands were used, with each child viewing a set of seven logos. The questionnaire assessed perceptions of food brands and perceptions of users of brands, using semantic differential scales, and perceived brand 'personalities', using Likert scales. New South Wales, Australia, October-November 2014. Children aged 10-16 years (n 417). Children demonstrated strong positive affect to certain brands, perceiving some unhealthy food brands to have positive attributes, desirable user traits and alignment to their own personality. Brand personality traits of 'smart' and 'sporty' were viewed as indicators of healthiness. Brands with these traits were ranked lower for popularity. Children's brand associations and attachments indicate the potential normative social influences of promotions. While children are aware of brand healthiness as an attribute, this competes with other brand associations, highlighting the challenge of health/nutrition messaging to counter unhealthy food marketing. Restricting children's exposure to unhealthy food marketing and the persuasive nature of marketing is an important part of efforts to improve children's diet-related health.

Miyama, T.; Kanda, J.; Iwasaki, R.; Sunohara, H.

1987-01-01

The purpose of this paper is to study fundamental effects of the frequency nonstationarity on the inelastic responses. First, the inelastic response characteristics are examined by applying stationary waves. Then simple representation of nonstationary characteristics is considered to general nonstationary input. The effects for frequency nonstationary response are summarized for inelastic systems. The inelastic response characteristics under white noise and simple frequency nonstationary wave were investigated, and conclusions can be summarized as follows. 1) The maximum response values for both BL model and OO model corresponds fairly well with those estimated from the energy constant law, even when R is small. For the OO model, the maximum displacement response forms a unique curve except for very small R. 2) The plastic deformation for the BL model is affected by wide frequency components, as R decreases. The plastic deformation for the OO model can be determined from the last stiffness. 3). The inelastic response of the BL model is considerably affected by the frequency nonstationarity of the input motion, while the response is less affected by the nonstationarity for OO model.

Exercise, Affect, and Adherence: An Evolutionary Perspective

Directory of Open Access Journals (Sweden)

Harold Lee

2016-08-01

Full Text Available The low rates of regular exercise and overall physical activity (PA in the general population represent a significant public health challenge. Previous research suggests that, for many people, exercise leads to a negative affective response and, in turn, reduced likelihood of future exercise. The purpose of this paper is to examine this exercise-affect-adherence relationship from an evolutionary perspective. Specifically, we argue that low rates of physical exercise in the general population are a function of the evolved human tendency to avoid unnecessary physical exertion. This innate tendency evolved because it allowed our evolutionary ancestors to conserve energy for physical activities that had immediate adaptive utility such as pursuing prey, escaping predators, and engaging in social and reproductive behaviors. The commonly observed negative affective response to exercise is an evolved proximate psychological mechanism through which humans avoid unnecessary energy expenditure. The fact that the human tendencies toward negative affective response to and avoidance of unnecessary physical activities are innate does not mean that they are unchangeable. Indeed, it is only because of human-engineered changes in our environmental conditions (i.e., it is no longer necessary for us to work for our food that our predisposition to avoid unnecessary physical exertion has become a liability. Thus, it is well within our capabilities to reengineer our environments to once again make PA necessary or, at least, to serve an immediate functional purpose. We propose a two-pronged approach to PA promotion based on this evolutionary functional perspective: First, to promote exercise and other physical activities that are perceived to have an immediate purpose, and second, to instill greater perceived purpose for a wider range of physical activities. We posit that these strategies are more likely to result in more positive (or at least less negative affective

Characterization and identification of microRNA core promoters in four model species.

Directory of Open Access Journals (Sweden)

Xuefeng Zhou

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.

Full Text Available Foreign Direct Investment (FDI not only affects the economic growth but also affects the environmental protection of the host country. With China’s background of pursuing green growth, we need to consider the performance of FDI from the economic and environmental benefit aspects. On this basis, using slacks-based measure directional distance function (SBMDDF to build up green growth efficiency, economic efficiency and environmental efficiency indexes, empirical research on FDI in 104 Chinese cities from 2004 to 2011 has shown that: (1 Different cities have differences in their green growth efficiency. Shenzhen city is always efficient in green economic growth. (2 Overall, FDI is positive on Chinese cities’ green growth. (3 When the green growth efficiency is broken down into economic efficiency and environmental efficiency, FDI promotes China’s economic green growth through both environmental benefits and economic benefits. (4 The effect of FDI differs in different sectors. FDI in the emission-intensive sector promotes green efficiency mainly through the improvement of economic efficiency. FDI in the non-emission-intensive sector promotes economic efficiency, environmental efficiency and green efficiency.

Full Text Available Affective aspect plays important role in man’s life, mainly in making decision, perception, interaction, communication and intelligence. A second behavior domain is the affective domain. The affective domain involves feelings, attitude, interests, preferences, values, and emotions. Emotional stability, motivation, trustworthiness, self-control, and personality are all examples of affective characteristics. Although affective behaviors are rarely assessed formally in schools and classrooms, teachers constantly assess affective behaviors informally, especially when sizing up students. Teachers need to know who can be trusted to work unsupervised and who cannot, who can maintain self-control when the teacher has to leave the classroom and who cannot, who needs to be encouraged to speak in class and who does not, who is interested in science but not in social studies, and who needs to be prodded to start class work and who does not. Most classroom teachers can describe their students’ affective characteristics based on their informal observations and interactions with the students. Statement of the Problem. a Exploration Phase.

Analysis of clustered point mutations in the human ribosomal RNA gene promoter by transient expression in vivo

International Nuclear Information System (INIS)

Jones, M.H.; Learned, R.M.; Tjian, R.

1988-01-01

The authors have mapped the cis regulatory elements required in vivo for initiation at the human rRNA promoter by RNA polymerase I. Transient expression in COS-7 cells was used to evaluate the transcription phenotype of clustered base substitution mutations in the human rRNA promoter. The promoter consists of two major elements: a large upstream region, composed of several domains, that lies between nucleotides -234 and -107 relative to the transcription initiation site and affects transcription up to 100-fold and a core element that lies between nucleotides -45 and +20 and affects transcription up to 1000-fold. The upstream regions is able to retain partial function when positioned within 100-160 nucleotides of the transcription initiation site, but it cannot stimulate transcription from distances of ≥ 600 nucleotides. In addition, they demonstrate, using mouse-human hybrid rRNA promoters, that the sequences responsible for human species-specific transcription in vivo appear to reside in both the core and upstream elements, and sequences from the mouse rRNA promoter cannot be substituted for them

Basolateral amygdala and stress-induced hyperexcitability affect motivated behaviors and addiction.

Science.gov (United States)

Sharp, B M

2017-08-08

The amygdala integrates and processes incoming information pertinent to reward and to emotions such as fear and anxiety that promote survival by warning of potential danger. Basolateral amygdala (BLA) communicates bi-directionally with brain regions affecting cognition, motivation and stress responses including prefrontal cortex, hippocampus, nucleus accumbens and hindbrain regions that trigger norepinephrine-mediated stress responses. Disruption of intrinsic amygdala and BLA regulatory neurocircuits is often caused by dysfunctional neuroplasticity frequently due to molecular alterations in local GABAergic circuits and principal glutamatergic output neurons. Changes in local regulation of BLA excitability underlie behavioral disturbances characteristic of disorders including post-traumatic stress syndrome (PTSD), autism, attention-deficit hyperactivity disorder (ADHD) and stress-induced relapse to drug use. In this Review, we discuss molecular mechanisms and neural circuits that regulate physiological and stress-induced dysfunction of BLA/amygdala and its principal output neurons. We consider effects of stress on motivated behaviors that depend on BLA; these include drug taking and drug seeking, with emphasis on nicotine-dependent behaviors. Throughout, we take a translational approach by integrating decades of addiction research on animal models and human trials. We show that changes in BLA function identified in animal addiction models illuminate human brain imaging and behavioral studies by more precisely delineating BLA mechanisms. In summary, BLA is required to promote responding for natural reward and respond to second-order drug-conditioned cues; reinstate cue-dependent drug seeking; express stress-enhanced reacquisition of nicotine intake; and drive anxiety and fear. Converging evidence indicates that chronic stress causes BLA principal output neurons to become hyperexcitable.

Identifying the factors that are associated with health-promoting behaviours in older adults is necessary to increase their willingness and motivation to participate in health-promotion activities. Understanding context-specific attitudes in relation to their influence on health-promoting behaviours is crucial in designing efficient interventions that foster health-promoting behaviours among older adults. This study aimed to examine the relationships between attitudes towards aging and health-promoting behaviours in older adults in Turkey. The study used a descriptive-correlational design. A convenience sample of 448 community-dwelling older adults who were 65 years and older and cognitively intact were selected from 6 family health centres in the city of Denizli in Turkey. The data were collected between March and June of 2014 using the Attitudes to Aging Questionnaire and the Health-Promoting Lifestyle Profile II. Multiple linear regression analysis was performed to explore the predictors of health-promoting behaviours. Attitudes toward aging, the psychosocial loss subscale, and education were statistically significant predictors of health-promoting behaviours. Attitudes toward aging were the strongest predictor of health-promoting behaviours in older adults. Attitude towards aging is a factor that affects health-promoting behaviours, and it should be considered during interventions for improving health promoting behaviours. © 2017 John Wiley & Sons Australia, Ltd.

The effect of hydrate promoters on gas uptake.

Xu, Chun-Gang; Yu, Yi-Song; Ding, Ya-Long; Cai, Jing; Li, Xiao-Sen

2017-08-16

Gas hydrate technology is considered as a promising technology in the fields of gas storage and transportation, gas separation and purification, seawater desalination, and phase-change thermal energy storage. However, to date, the technology is still not commercially used mainly due to the low gas hydrate formation rate and the low gas uptake. In this study, the effect of hydrate promoters on gas uptake was systematically studied and analyzed based on hydrate-based CH 4 storage and CO 2 capture from CO 2 /H 2 gas mixture experiments. Raman spectroscopy, Fourier transform infrared spectroscopy (FTIR) and gas chromatography (GC) were employed to analyze the microstructures and gas compositions. The results indicate that the effect of the hydrate promoter on the gas uptake depends on the physical and chemical properties of the promoter and gas. A strong polar ionic promoter is not helpful towards obtaining the ideal gas uptake because a dense hydrate layer is easily formed at the gas-liquid interface, which hinders gas diffusion from the gas phase to the bulk solution. For a weak polar or non-polar promoter, the gas uptake depends on the dissolution characteristics among the different substances in the system. The lower the mutual solubility among the substances co-existing in the system, the higher the independence among the substances in the system; this is so that each phase has an equal chance to occupy the hydrate cages without or with small interactions, finally leading to a relatively high gas uptake.

Carmen María Villalobos González

2014-01-01

Full Text Available This essay reflects on those teaching experiences that have a strong influence on students and allow teachers to grow as individuals as well as professionals.  The author approaches positive affection towards students, which allows children to be emotionally well adjusted, consequently, promoting their desire to learn, attend classes, and have good social relationships with their peers, and allows teachers to have confidence and high self-esteem. Emphasis is placed on the fact that educators must treat students well, know their family environment, solve their emotional deficiencies, if any, and show empathy towards them. In short, teachers are encouraged to give priority to affective relationships in their pedagogical practice.  The author also includes some experiences from her professional practices, where affection towards children was essential.

In Vancouver schools, food-related promotions are common and are more prevalent in secondary than elementary schools. Students are regularly exposed to messaging for nutritionally poor items that are not in compliance with provincial school nutrition guidelines and which violate school board advertising policies. Stronger oversight of food-related promotional materials is needed to ensure that schools provide health promoting food environments.

Statistical characteristics of serious network failures in Japan

Due to significant environmental changes in the telecommunications market, network failures affect socioeconomic activities more than ever before. However, the health of public networks at a national level has not been investigated in detail. In this paper, we investigate the statistical characteristics of interval, duration, and the number of users affected for serious network failures, which are defined as network failures that last for more than two hours and affect more than 30,000 users, that occurred in Japan during Japanese fiscal years 2008–2012 (April 2008–March 2013). The results show that (i) the interval follows a Poisson process, (ii) the duration follows a Pareto distribution, (iii) the number of users affected follows a piecewise Pareto distribution, (iv) the product of duration and the number of users affected roughly follow a distribution that can be derived from a convolution of two distributions of duration and the number of users affected, and (v) the relationship between duration and the number of users affected differs from service to service. - Highlights: • The statistical characteristics of serious network failures in Japan are analyzed. • The analysis is based on public information that is available at the moment. • The interval follows a Poisson process. • The duration follows a Pareto distribution. • The number of users affected follows a piecewise Pareto distribution

Tumor-promoting phorbol esters effect alkalinization of canine renal proximal tubular cells

International Nuclear Information System (INIS)

Mellas, J.; Hammerman, M.R.

1986-01-01

We have demonstrated the presence of specific receptors for tumor-promoting phorbol esters in the plasma membrane of the canine renal proximal tubular cell. These compounds affect proximal tubular metabolism in vitro. For example, we have shown that they inhibit gluconeogenesis in canine renal proximal tubular segments. Tumor-promoting phorbol esters have been shown to effect alkalinization of non-renal cells, by enhancing Na + -H + exchange across the plasma membrane. To determine whether the actions of tumor-promoting phorbol esters in proximal tubular segments might be mediated by a similar process, we incubated suspensions of segments from dog kidney with these compounds and measured changes in intracellular pH using [ 14 C]-5,5-dimethoxazoladine-2-4-dione (DMO) and flow dialysis. Incubation of segments with phorbol 12,13 dibutyrate, but not inactive phorbol ester, 4 γ phorbol, effected alkalinization of cells within the segments in a concentration-dependent manner. Alkalinization was dependent upon the presence of extracellular [Na + ] > intracellular [Na + ], was prevented by amiloride and was demonstrable in the presence of SITS. Our findings suggest that tumor-promoting esters stimulate the Na + -H + exchanger known to be present in the brush border membrane of the renal proximal tubular cell. It is possible that the stimulation reflects a mechanism by which phorbol esters affect metabolic processes in these cells

French bio-diesel demand and promoting measures analysis by 2010

International Nuclear Information System (INIS)

Bernard, F.

2008-02-01

The researches presented aim at assessing bio-diesel promoting measures under consideration in France by 2010. This assessment is based on a deep study of French bio-diesel demand. The use of a linear model for optimizing the whole French refining industry costs allow us to take into account the physicochemical characteristics of bio-diesel useful for gas oil blending operation. This researches show that bio-diesel can be incorporated up to 27% blend in volume to diesel fuel without major technical problem. A decomposition of the value allotted to the bio-diesel by French refiners according to its physicochemical characteristics shows that energy content is the most disadvantageous characteristics for bio-diesel incorporation and, up to 17%, density become also constraining. However, the low bio-diesel sulphur content could become interesting from now to 2010. On the basis of this bio-diesel demand analysis, we proceed to an external coupling of an agro-industrial model of bio-diesel supply with the French refining model. Thus, we study the impact of the 2010 French bio-diesel consumption objective on agricultural surface need, the competitiveness of the bio-diesel, the reduction of greenhouse gases emissions and the trade balance of the petroleum products. On this basis, we propose a critical analysis of French bio-diesel promoting measures under consideration by 2010. (author)

Universities are dynamic environments. But university life presents challenges that may affect the mental health of its community. Higher education institutions provide opportunities to promote public health. Our objective is to summarise the current evidence on strategies to promote mental health at the university, following a setting-based model. We conducted a systematic literature review following standard methods. Published literature that evaluated structural and organizations strategies to promote mental health at the university was selected. 19 papers were included. The majority of the studies were targeting the students, with only four aiming to promote employees' mental health. The most promising strategies to promote mental wellbeing included changes in the way students are taught and assessed. On the other hand, social marketing strategies had not impact on mental health. There is inconclusive evidence related to the effectiveness of policies to promote mental health. Universities should invest in creating supportive physical, social and academic environments that promote student and staff mental wellbeing. However, the current body of evidence is scarce and more research is needed to recommend what are the best strategies.

Hepatocellular carcinoma (HCC) is one of the leading causes of cancer-related deaths worldwide. Current therapies are insufficient, making HCC an intractable disease. Our previous studies confirmed that inhibition of protein phosphatase 2A (PP2A) may provide a promising therapeutic strategy for cancer. Unfortunately, constitutive expression of PP2A in normal tissues limits the application of PP2A inhibition. Thus, a HCC-specific gene delivery system should be developed. The α-fetoprotein (AFP) promoter is commonly used in HCC-specific gene therapy strategies; however, the utility of this approach is limited due to the weak activity of the AFP promoter. It has been shown that linking the AFP enhancer with the promoter of the non-tissue-specific, human housekeeping phosphoglycerate kinase (pgk) gene can generate a strong and HCC-selective promoter. We constructed a HCC-specific gene therapy system to target PP2A using the AFP enhancer/pgk promoter, and evaluated the efficiency and specificity of this system both in vitro and in vivo. AFP enhancer/pgk promoter-driven expression of the dominant negative form of the PP2A catalytic subunit α (DN-PP2Acα) exerted cytotoxic effects against an AFP-positive human hepatoma cell lines (HepG2 and Hep3B), but did not affect AFP-negative human hepatoma cells (SK-HEP-1) or normal human liver cells (L-02). Moreover, AFP enhancer/pgk promoter driven expression of DN-PP2Acα inhibited the growth of AFP-positive HepG2 tumors in nude mice bearing solid tumor xenografts, but did not affect AFP-negative SK-HEP-1 tumors. The novel approach of AFP enhancer/pgk promoter-driven expression of DN-PP2Acα may provide a useful cancer gene therapy strategy to selectively target HCC

The analysis of the microscopic view of mixed traffic offers a basis for resolving traffic jams which are inhomogeneous due to several types of vehicles. In this study, we research the dependence of driving characteristics upon vehicle order in a platoon. By focusing particularly upon the manner in which the driving characteristics of a follower are affected by both their own vehicle type and that of their leader, we measured the trajectories of platoons comprising two vehicles selected from motorcycles, passenger cars, and trucks on a test course. Analysis based on vehicle order showed that the vehicle types of both the leader and the follower as well as the leader's driving characteristics affected the velocity, acceleration, deceleration, operational delay of followers, and the distance gap between leaders and followers in different ways. In addition, we investigated the factors affecting driving characteristics by multiple regression analysis. We revealed that the operational delay and the maximum distance gap tend to be large when the length of leaders is large. Furthermore, as long as a follower can follow, we need not consider vehicle types among the parameters determining maximum velocity in car-following models. The vehicle types of the leader and the follower should be considered to determine maximum acceleration. When determining maximum deceleration, the vehicle types of the follower should be considered.

The objectives of this study were to describe the locations in hospitals where data are breached, the types of breaches that occur most often at hospitals, and hospital characteristics, including health information technology (IT) sophistication and biometric security capabilities, that may be predicting factors of large data breaches that affect 500 or more patients. The Office of Civil Rights breach data from healthcare providers regarding breaches that affected 500 or more individuals from 2009 to 2016 were linked with hospital characteristics from the Health Information Management Systems Society and the American Hospital Association Health IT Supplement databases. Descriptive statistics were used to characterize hospitals with and without breaches, data breach type, and location/mode of data breaches in hospitals. Multivariate logistic regression analysis explored hospital characteristics that were predicting factors of a data breach affecting at least 500 patients, including area characteristics, region, health system membership, size, type, biometric security use, health IT sophistication, and ownership. Of all types of healthcare providers, hospitals accounted for approximately one-third of all data breaches and hospital breaches affected the largest number of individuals. Paper and films were the most frequent location of breached data, occurring in 65 hospitals during the study period, whereas network servers were the least common location but their breaches affected the most patients overall. Adjusted multivariate results showed significant associations among data breach occurrences and some hospital characteristics, including type and size, but not others, including health IT sophistication or biometric use for security. Hospitals should conduct routine audits to allow them to see their vulnerabilities before a breach occurs. Additionally, information security systems should be implemented concurrently with health information technologies. Improving

We recorded pulmonary ventilation (VE), oxygen consumption (VO2) for EE esteem and heart rate (HR) at rest and while playing virtual bowling, tennis and boxing games using a portable metabolimeter equipped with ECG electrodes. The standard metabolic equivalent of task (METs) was calculated offline. The metabolic and functional parameters were referred to the 10th minute of each activity. Metabolic and functional parameters increased significantly from rest to bowling, tennis and boxing. METs exceeded in average 3 during boxing. One hour of APVG can increase daily EE by about 6% (bowling), 10% (tennis) and 15% (boxing). These considerable results suggest that physical exertion during APVG practice in subjects with SCI could contribute to health promotion as well as caloric balance control, especially when boxing is considered. This can be safely achieved at home with regular activity. These findings substantiate the potential for novel exercise modalities to counteract deconditioning due to inactivity in subjects with SCI by promoting physical activity through implementation of APVG exercise programs.

In this paper, we examine how job assignments affect gender pay gap and the promotion rate of female workers using personnel records from a large Japanese manufacturing firm, where newly-hired male and female workers are systematically assigned to different workplaces ("gender job segregation"). According to our gender pay gap analysis, we find that controlling for workplace heterogeneity leads to a larger, rather than smaller, gender pay gap, implying that female workers are sorted into work...

Osteoponin Promoter Controlled by DNA Methylation: Aberrant Methylation in Cloned Porcine Genome

2014-01-01

Full Text Available Cloned animals usually exhibited many defects in physical characteristics or aberrant epigenetic reprogramming, especially in some important organ development. Osteoponin (OPN is an extracellular-matrix protein involved in heart and bone development and diseases. In this study, we investigated the correlation between OPN mRNA and its promoter methylation changes by the 5-aza-dc treatment in fibroblast cell and promoter assay. Aberrant methylation of porcine OPN was frequently found in different tissues of somatic nuclear transferred cloning pigs, and bisulfite sequence data suggested that the OPN promoter region −2615 to −2239 nucleotides (nt may be a crucial regulation DNA element. In pig ear fibroblast cell culture study, the demethylation of OPN promoter was found in dose-dependent response of 5-aza-dc treatment and followed the OPN mRNA reexpression. In cloned pig study, discrepant expression pattern was identified in several cloned pig tissues, especially in brain, heart, and ear. Promoter assay data revealed that four methylated CpG sites presenting in the −2615 to −2239 nt region cause significant downregulation of OPN promoter activity. These data suggested that methylation in the OPN promoter plays a crucial role in the regulation of OPN expression that we found in cloned pigs genome.

Poor adventitious root (AR) formation is a major obstacle in micropropagation and conventional vegetative propagation of many crops. It is affected by many endogenous and exogenous factors. With respect to endogenous factors, the phase change from juvenile to adult has a major influence on AR formation and rooting is usually much reduced or even fully inhibited in adult tissues. It has been reported that the phase change is characterized by an increase in DNA-methylation and a decrease in the expression of microRNA156 (miR156). In this paper, we examined the effect of azacytidine (AzaC) and miR156 on AR formation in adult and juvenile Arabidopsis tissues. To identify the ontogenetic state researchers have used flowering or leaf morphology. We have used the rootability which allows - in contrast with both other characteristics- to examine the ontogenetic state at the cellular level. Overexpression of miR156 promoted only the rooting of adult tissues indicating that the phase change-associated loss in tissues' competence to develop ARs is also under the control of miR156. Azacytidine inhibits DNA methylation during DNA replication. Azacytidine treatment also promoted AR formation in nonjuvenile tissues but had no or little effect in juvenile tissues. Its addition during seedling growth (by which all tissues become hypomethylated) or during the rooting treatment (by which only those cells become hypomethylated that are generated after taking the explant) are both effective in the promotion of rooting. An AzaC treatment may be useful in tissue culture for crops that are recalcitrant to root. Copyright © 2016 Elsevier GmbH. All rights reserved.

Mobile phone tasks like texting, typing, and dialling during walking are known to impact gait characteristics. Beyond that, the effects of performing smartphone-typical actions like researching and taking self-portraits (selfie) on gait have not been investigated yet. We aimed to investigate the effects of smartphone usage on relevant gait characteristics and to reveal potential association of basic cognitive and walking plus smartphone dual-task abilities. Our cross-sectional, cross-over study on physically active, healthy participants was performed on two days, interrupted by a 24-h washout in between. Assessments were: 1) Cognitive testing battery consisting of the trail making test (TMT A and B) and the Stroop test 2) Treadmill walking under five smartphone usage conditions: no use (control condition), reading, dialling, internet searching and taking a selfie in randomized order. Kinematic and kinetic gait characteristics were assessed to estimate conditions influence. In our sample of 36 adults (24.6 ± 1 years, 23 female, 13 male), ANCOVAs followed by post-hoc t-tests revealed that smartphone usage impaired all tested gait characteristics: gait speed (decrease, all conditions): F = 54.7, p smartphone usage was systematically associated with the TMT B time regarding cadence and double stride length for reading (r = -0.37), dialling (r = -0.35) and taking a selfie (r = -0.34). Smartphone usage substantially impacts walking characteristics in most situations. Changes of gait patterns indicate higher cognitive loads and lower awareness. Copyright © 2018 Elsevier B.V.

dimension lead to high positive affect when negative affect is high (i.e., self-destructive vs. high affective) but to low negative affect when positive affect was high (i.e., high affective vs. self-fulfilling). The moderation analyses showed, for example, that for individuals with a self-destructive profile, psychological well-being was significantly predicted by the past negative, present fatalistic and future time perspectives. Among individuals with a high affective or a self-fulfilling profile, psychological well-being was significantly predicted by the present fatalistic dimension. Conclusions. The interactions found here go beyond the postulation of a "balanced" time perspective being the only way to promote well-being. Instead, we present a more person-centered approach to achieve higher levels of emotional, cognitive, and psychological well-being.

Fibrosis affects most organs, it results in replacement of normal parenchymal tissue with collagen-rich extracellular matrix, which compromises tissue architecture and ultimately causes loss of function of the affected organ. Biochemical pathways that contribute to fibrosis have been extensively studied, but the role of biomechanical signaling in fibrosis is not clearly understood. In this study, we assessed the effect keratinocytes have on the biomechanical characteristics and pore microstructure of tissue engineered skin made with superficial or deep dermal fibroblasts in order to determine any biomaterial-mediated anti-fibrotic influences on tissue engineered skin. Tissue engineered skin with deep dermal fibroblasts and keratinocytes were found to be less stiff and contracted and had reduced number of myofibroblasts and lower expression of matrix crosslinking factors compared to matrices with deep fibroblasts alone. However, there were no such differences between tissue engineered skin with superficial fibroblasts and keratinocytes and matrices with superficial fibroblasts alone. Also, tissue engineered skin with deep fibroblasts and keratinocytes had smaller pores compared to those with superficial fibroblasts and keratinocytes; pore size of tissue engineered skin with deep fibroblasts and keratinocytes were not different from those matrices with deep fibroblasts alone. A better understanding of biomechanical characteristics and pore microstructure of tissue engineered skin may prove beneficial in promoting normal wound healing over pathologic healing.

Effect of plant growth-promoting bacteria on the growth and fructan production of Agave americana L.

Directory of Open Access Journals (Sweden)

Neyser De La Torre-Ruiz

Full Text Available ABSTRACT The effect of plant growth-promoting bacteria inoculation on plant growth and the sugar content in Agave americana was assessed. The bacterial strains ACO-34A, ACO-40, and ACO-140, isolated from the A. americana rhizosphere, were selected for this study to evaluate their phenotypic and genotypic characteristics. The three bacterial strains were evaluated via plant inoculation assays, and Azospirillum brasilense Cd served as a control strain. Phylogenetic analysis based on the 16S rRNA gene showed that strains ACO-34A, ACO-40 and ACO-140 were Rhizobium daejeonense, Acinetobacter calcoaceticus and Pseudomonas mosselii, respectively. All of the strains were able to synthesize indole-3-acetic acid (IAA, solubilize phosphate, and had nitrogenase activity. Inoculation using the plant growth-promoting bacteria strains had a significant effect (p < 0.05 on plant growth and the sugar content of A. americana, showing that these native plant growth-promoting bacteria are a practical, simple, and efficient alternative to promote the growth of agave plants with proper biological characteristics for agroindustrial and biotechnological use and to increase the sugar content in this agave species.

Caffeine promotes wakefulness via dopamine signaling in Drosophila

Nall, Aleksandra H.; Shakhmantsir, Iryna; Cichewicz, Karol; Birman, Serge; Hirsh, Jay; Sehgal, Amita

2016-01-01

Caffeine is the most widely-consumed psychoactive drug in the world, but our understanding of how caffeine affects our brains is relatively incomplete. Most studies focus on effects of caffeine on adenosine receptors, but there is evidence for other, more complex mechanisms. In the fruit fly Drosophila melanogaster, which shows a robust diurnal pattern of sleep/wake activity, caffeine reduces nighttime sleep behavior independently of the one known adenosine receptor. Here, we show that dopamine is required for the wake-promoting effect of caffeine in the fly, and that caffeine likely acts presynaptically to increase dopamine signaling. We identify a cluster of neurons, the paired anterior medial (PAM) cluster of dopaminergic neurons, as the ones relevant for the caffeine response. PAM neurons show increased activity following caffeine administration, and promote wake when activated. Also, inhibition of these neurons abrogates sleep suppression by caffeine. While previous studies have focused on adenosine-receptor mediated mechanisms for caffeine action, we have identified a role for dopaminergic neurons in the arousal-promoting effect of caffeine.

The enterocin AS-48 is the best characterized antibacterial circular protein in prokaryotes. It is a hydrophobic and cationic bacteriocin, which is ribosomally synthesized by enterococcal cells and post-translationally cyclized by a head-to-tail peptide bond. The production of and immunity towards AS-48 depend upon the coordinated expression of ten genes organized in two operons, as-48ABC (where genes encoding enzymes with processing, secretion, and immunity functions are adjacent to the structural as-48A gene) and as-48C1DD1EFGH. The current study describes the identification of the promoters involved in AS-48 expression. Seven putative promoters have been here amplified, and separately inserted into the promoter-probe vector pTLR1, to create transcriptional fusions with the mCherry gene used as a reporter. The activity of these promoter regions was assessed measuring the expression of the fluorescent mCherry protein using the constitutive pneumococcal promoter PX as a reference. Our results revealed that only three promoters PA, P2(2) and PD1 were recognized in Enterococcus faecalis, Lactococcus lactis and Escherichia coli, in the conditions tested. The maximal fluorescence was obtained with PX in all the strains, followed by the P2(2) promoter, which level of fluorescence was 2-fold compared to PA and 4-fold compared to PD1. Analysis of putative factors influencing the promoter activity in single and double transformants in E. faecalis JH2-2 demonstrated that, in general, a better expression was achieved in presence of pAM401-81. In addition, the P2(2) promoter could be regulated in a negative fashion by genes existing in the native pMB-2 plasmid other than those of the as-48 cluster, while the pH seems to affect differently the as-48 promoter expression.

These defects may affect the dynamic characteristics of tubes, and therefore, the vibrational behavior of the tube due to flow-induced loads can be varied. Change in the vibrational response of a tube may result in different wear characteristics from the design condition, which must be checked for both safety and economic point of view. This paper deals with the study on the effect of wears or cracks on the dynamic characteristics of steam generator tubes using finite element analysis. In this paper the effect of defects on the surface due to wear on the variation of dynamic characteristics of steam generator tubes was studied using the finite element analysis. The changes of natural frequencies and mode shapes can directly affect the flow-induced vibration response characteristics, therefore, they must be evaluated appropriately. The results in this study can be a good basis to estimate the FIV characteristics of the steam generator tubes having defects such as wear or crack.

Social capital and health--implications for health promotion.

Science.gov (United States)

Eriksson, Malin

2011-02-08

This article is a review of the PhD Thesis of Malin Eriksson, entitled 'Social capital, health and community action - implications for health promotion.' The article presents a theoretical overview of social capital and its relation to health, reviews empirical findings of the links between social capital and (self-rated) health, and discusses the usefulness of social capital in health promotion interventions at individual and community levels. Social capital, conceptualized as an individual characteristic, can contribute to the field of health promotion by adding new knowledge on how social network interventions may best be designed to meet the needs of the target group. The distinction of different forms of social capital, i.e. bonding, bridging, and linking, can be useful in mapping the kinds of networks that are available and health-enhancing (or damaging) and for whom. Further, social capital can advance social network interventions by acknowledging the risk for unequal distribution of investments and returns from social network involvement. Social capital, conceptualized as characterizing whole communities, provides a useful framework for what constitutes health-supporting environments and guidance on how to achieve them. Mapping and mobilization of social capital in local communities may be one way of achieving community action for health promotion. Social capital is context-bound by necessity. Thus, from a global perspective, it cannot be used as a 'cookbook' on how to achieve supportive environments and community action smoothly. However, social capital can provide new ideas on the processes that influence human interactions, cooperation, and community action for health promotion in various contexts. © 2011 Malin Eriksson.

Social networks, health promoting-behavior, and health-related quality of life in older Korean adults.

In this cross-sectional, descriptive study, we compared the sociodemographic characteristics, social networks, health-promoting behavior, and the health-related quality of life of older Korean adults living in South Korea to those of older Korean adult immigrants living in the USA. A total of 354 older adults, aged 65 years or older, participated. Data were collected through self-directed questionnaires, and analyzed using a two way analysis of variance, t-tests, χ 2 -tests, and Pearson's correlation coefficient. The association between four sociodemographic characteristics and health-related quality of life was significantly different between the two groups. For the older Korean adults living in South Korea, positive correlations existed between a measure of their social networks and both health-promoting behavior and health-related quality of life. For the older Korean immigrants, the findings revealed a positive correlation only between social networks and health-promoting behavior. The study findings support the important association social networks can have with health-related quality of life, and their possible relationship to health-promoting behaviors of older Korean adults. We suggest that health policy-makers and healthcare providers develop comprehensive programs that are designed to improve older adults' social networks. © 2017 John Wiley & Sons Australia, Ltd.

2018-01-01

The three-dimensional (3D) behavior characteristics of bubble rising in gas-liquid two-phase flow are of great importance to study bubbly flow mechanism and guide engineering practice. Based on the dual-perspective imaging of virtual binocular stereo vision, the 3D behavior characteristics of bubbles in gas-liquid two-phase flow are studied in detail, which effectively increases the projection information of bubbles to acquire more accurate behavior features. In this paper, the variations of bubble equivalent diameter, volume, velocity and trajectory in the rising process are estimated, and the factors affecting bubble behavior characteristics are analyzed. It is shown that the method is real-time and valid, the equivalent diameter of the rising bubble in the stagnant water is periodically changed, and the crests and troughs in the equivalent diameter curve appear alternately. The bubble behavior characteristics as well as the spiral amplitude are affected by the orifice diameter and the gas volume flow.

To determine if there is a relationship between the risk of postoperative complications and the nonclinical hospital characteristics of bed size, ownership structure, relative urbanicity, regional location, teaching status, and area income status. This study involved a secondary analysis of 2006 administrative hospital data from a number of U.S. states. This data, gathered annually by the Agency for Healthcare Research and Quality (AHRQ) via the National Inpatient Sample (NIS) Healthcare Utilization Project (HCUP), was analyzed using probit regressions to measure the effects of several nonclinical hospital categories on seven diagnostic groupings. The study model included postoperative complications as well as additional potentially confounding variables. The results showed mixed outcomes for each of the hospital characteristic groupings. Subdividing these groupings to correspond with the HCUP data analysis allowed a greater understanding of how hospital characteristics' may affect postoperative outcomes. Nonclinical hospital characteristics do affect the various postoperative complications, but they do so inconsistently.

The progression of life in all forms is not only dependent on agricultural and food security but also on the soil characteristics. The dynamic nature of soil is a direct manifestation of soil microbes, bio-mineralization, and synergistic co-evolution with plants. With the increase in world's population the demand for agriculture yield has increased tremendously and thereby leading to large scale production of chemical fertilizers. Since the use of fertilizers and pesticides in the agricultural fields have caused degradation of soil quality and fertility, thus the expansion of agricultural land with fertile soil is near impossible, hence researchers and scientists have sifted their attention for a safer and productive means of agricultural practices. Plant growth promoting rhizobacteria (PGPR) has been functioning as a co-evolution between plants and microbes showing antagonistic and synergistic interactions with microorganisms and the soil. Microbial revitalization using plant growth promoters had been achieved through direct and indirect approaches like bio-fertilization, invigorating root growth, rhizoremediation, disease resistance etc. Although, there are a wide variety of PGPR and its allies, their role and usages for sustainable agriculture remains controversial and restricted. There is also variability in the performance of PGPR that may be due to various environmental factors that might affect their growth and proliferation in the plants. These gaps and limitations can be addressed through use of modern approaches and techniques such as nano-encapsulation and micro-encapsulation along with exploring multidisciplinary research that combines applications in biotechnology, nanotechnology, agro biotechnology, chemical engineering and material science and bringing together different ecological and functional biological approaches to provide new formulations and opportunities with immense potential.

French bio-diesel demand and promoting measures analysis by 2010; Analyse de la demande et des mesures de promotion francaises du biodiesel a l'horizon 2010

Energy Technology Data Exchange (ETDEWEB)

Bernard, F

2008-02-15

The researches presented aim at assessing bio-diesel promoting measures under consideration in France by 2010. This assessment is based on a deep study of French bio-diesel demand. The use of a linear model for optimizing the whole French refining industry costs allow us to take into account the physicochemical characteristics of bio-diesel useful for gas oil blending operation. This researches show that bio-diesel can be incorporated up to 27% blend in volume to diesel fuel without major technical problem. A decomposition of the value allotted to the bio-diesel by French refiners according to its physicochemical characteristics shows that energy content is the most disadvantageous characteristics for bio-diesel incorporation and, up to 17%, density become also constraining. However, the low bio-diesel sulphur content could become interesting from now to 2010. On the basis of this bio-diesel demand analysis, we proceed to an external coupling of an agro-industrial model of bio-diesel supply with the French refining model. Thus, we study the impact of the 2010 French bio-diesel consumption objective on agricultural surface need, the competitiveness of the bio-diesel, the reduction of greenhouse gases emissions and the trade balance of the petroleum products. On this basis, we propose a critical analysis of French bio-diesel promoting measures under consideration by 2010. (author)

Affective disorders in childhood and adolescence

Full Text Available Affective disorders in childhood have been more intensively studied in the last three decades. They can be recognized among the children of all ages, but are more frequent among the older children. The main characteristics of mood disorders are similar among children, adolescents and adults, although development factors affect their clinical features. Development factors affect the manifestation of all symptoms. Two main criteria for these disorders in childhood are mood disorders, such as reduced or elevated mood and irritability. These symptoms may result in social or academic damage. Depression among children is a wide-spread, family and recurrent condition, which continues episodically in adulthood. Depression is frequently associated with other psychiatric disorders, increasing the risk of suicidal behaviour, misuse of psychoactive substances and behavioural disorders. Depression in childhood brings about worse psychosocial, academic and family functioning. Family, social and environmental factors have a significant role in affective disorders of children and young people.

Threat ≠ prevention, challenge ≠ promotion: the impact of threat, challenge and regulatory focus on attention to negative stimuli.

2015-01-01

The purpose of the current experiment was to distinguish between the impact of strategic and affective forms of gain- and loss-related motivational states on the attention to negative stimuli. On the basis of the counter-regulation principle and regulatory focus theory, we predicted that individuals would attend more to negative than to neutral stimuli in a prevention focus and when experiencing challenge, but not in a promotion focus and under threat. In one experiment (N = 88) promotion, prevention, threat, or challenge states were activated through a memory task, and a subsequent dot probe task was administered. As predicted, those in the prevention focus and challenge conditions had an attentional bias towards negative words, but those in promotion and threat conditions did not. These findings provide support for the idea that strategic mindsets (e.g., regulatory focus) and hot emotional states (e.g., threat vs. challenge) differently affect the processing of affective stimuli.

An estimated 43.5 million American adults currently smoke cigarettes. Well-designed tobacco education campaigns with adequate reach increase cessation and reduce tobacco use. Smokers report great interest in quitting but few use effective treatments including quitlines (QLs). This review examined traditional (TV, radio, print ads) versus innovative tobacco cessation (internet, social media) promotions for QL services. Between November 2011 and January 2012, searches were conducted on EBSCO, PubMed, Wilson, OCLC, CQ Press, Google Scholar, Gale, LexisNexis, and JSTOR. Existing literature shows that the amount of radio and print advertising, and promotion of free cessation medications increases QL call volume. Television advertising volume seems to be the best predictor of QL service awareness. Much of the literature on Internet advertising compares the characteristics of participants recruited for studies through various channels. The majority of the papers indicated that Internet-recruited participants were younger; this was the only demographic characteristic with high agreement across studies. Traditional media was only studied within mass media campaigns with TV ads having a consistent impact on increasing calls to QLs, therefore, it is hard to distinguish the impact of traditional media as an independent QL promotion intervention. With innovative media, while many QL services have a presence on social media sites, there is no literature on evaluating the effectiveness of these channels for quitline promotion.

Today chronic non-communicable diseases are the major cause of death and disability worldwide. Chronic diseases are determined by common risk factors (e.g. smoking). The purpose of this study was to develop a health-promoting behaviour index, and to evaluate the impact of the social and the demographic characteristics of the individuals, self-rated health and certain features of settlements on the score of this index. A population-based, cross-sectional health survey was conducted. Altogether 91 settlements with various sizes of population, and at various stages of social, economic and infrastructural development took part in the survey. The survey was based on interviewer-administered questionnaires, 3380 subjects filled in the questionnaires correctly, and the response rate was 82.4%. Questions on lifestyle factors referred to smoking, nutritional habits and physical activity. Low level (5.5%) of people have achieved the 'complete' health-promoting behaviour, including non-smoking, healthy nutrition and physical activity. There were significant associations between health-promoting behaviour and demographic, social and economic characteristics of the individuals and their dwelling place. The lower prevalence of healthy lifestyle activities among lower educated, lower income and aged people living in small settlements call the attention to the higher risk of these people. On planning interventions, special attention should be paid to the geographically, infrastructurally, socially and demographically disadvantaged population groups to provide equal opportunities for them, to live a healthy way of life. The application of the health-promoting index might be used to monitor the effects of interventions to alter lifestyle at community level.

Informal workers often face considerable risks and vulnerabilities as a consequence of their work and employment conditions. The purpose of this study was to examine the interplay between the experience of informal work and access to health, using as an example, female beer promoters employed in the informal economy, in the Lao People's Democratic Republic. In-depth interviews were undertaken with 24 female beer promoters working in beer shops, restaurants and entertainment venues in Vientiane City. The recruitment strategy of snowball sampling was used. Interviews explored the beer promoter's experience of the organization of work, perceived healthcare needs, access to healthcare and insurance, and health seeking practices. The data was analysed thematically and subsequently using Bourdieu's concepts of habitus, capital and field. Most of the beer promoters included in the study were 18 years of age, single, had worked as beer promoters for more than one year and just over half were working to support their higher education. The beer promoters demonstrated a holistic view of health, also viewing good health as contributing to being beautiful - an important attribute in their work. Many reported that their work conditions, including the noisy environment, exposure to second-hand tobacco smoke, long hours on their feet and sexual harassment negatively affected their physical and mental health. Only four participants had any form of health insurance with access to healthcare constrained by individual characteristics, health system factors and the conditions of their informal employment. Drawing on the work of Bourdieu, the study shows how both employment and illness are linked to habitus embodied in everyday practices, access to capital and the position the female beer promoters hold in the social hierarchy in the field of employment.

The role of social innovations in transforming the lives of individuals and communities has been a source of popular attention in recent years. This article systematically reviews the available evidence of the relationship between social innovation and its promotion of health equity. Guided by Fair Foundations: The VicHealth framework for health equity and examining four types of social innovation--social movements, service-related social innovations, social enterprise and digital social innovations--we find a growing literature on social innovation activities, but inconsistent evaluative evidence of their impacts on health equities, particularly at the socio-economic, political and cultural level of the framework. Distinctive characteristics of social innovations related to the promotion of health equity include the mobilization of latent or unrealised value through new combinations of (social, cultural and material) resources; growing bridging social capital and purposeful approaches to linking individual knowledge and experience to institutional change. These have implications for health promotion practice and for research about social innovation and health equity. © The Author 2015. Published by Oxford University Press. All rights reserved.

For well over a century, scientists have investigated individual differences in performance. The majority of studies have focused on either differences in practice, or differences in cognitive resources. However, the predictive ability of either practice or cognitive resources varies considerably across tasks. We are the first to examine task characteristics' impact on learning and performance in a complex task while controlling for other task characteristics. In 2 experiments we test key theoretical task characteristic thought to moderate the relationship between practice, cognitive resources, and performance. We devised a task where each of several key task characteristics can be manipulated independently. Participants played 5 rounds of a game similar to the popular tower defense videogame Plants vs. Zombies where both cognitive load and game characteristics were manipulated. In Experiment 1, participants either played a consistently mapped version-the stimuli and the associated meaning of their properties were constant across the 5 rounds-or played a variably mapped version-the stimuli and the associated meaning of their properties changed every few minutes. In Experiment 2, participants either played a static version-that is, turn taking with no time pressure-or played a dynamic version-that is, the stimuli moved regardless of participants' response rates. In Experiment 1, participants' accuracy and efficiency were substantially hindered in the variably mapped conditions. In Experiment 2, learning and performance accuracy were hindered in the dynamic conditions, especially when under cognitive load. Our results suggest that task characteristics impact the relative importance of cognitive resources and practice on predicting learning and performance.

2016-01-01

There has been a marked increase in the number of physicians marketing themselves directly to patients and consumers. However, it is unclear how different promotional styles affect patients' perceptions of their physicians. We hypothesized that self-promoting orthopedic surgeons enjoy a more positive impact on nonphysician patients as compared to non-self-promoting surgeons, as well as a corresponding negative impact on their peer-surgeons. Surgeon websites were selected from the 5 largest population centers in the United States. Subjects with varying degrees of familiarity with orthopedic surgery evaluated Internet profiles of surgeons on a forced choice Likert scale to measure the amount of self-promotion. The naïve subjects judged self-promoting surgeons more favorably than the orthopedic surgeons. In contrast, board-certified orthopedic surgeons viewed self-promoting surgeons more negatively than did their nonphysician counterparts. In summary, the present study revealed that the potential for self-promotion to unduly influence potential patients is real and should be a considerable concern to surgeons, patients, and the profession.

2017-11-01

Process of brown coal oxidation with 5%wt content of copper-salt additives of various nature (Cu (NO3)2, CuSO4 and Cu(CH3COO)2) was studied. The experiment has been performed by thermogravimetric analysis at a heating rate of 2.5°C/min to a maximum temperature of 600°C in the air. Analytical evaluation of oxidation process kinetic characteristics has been conducted based on the results of TGA. It has been established that addition of initiating agents leads to significant reduction in the initial ignition temperature of coal (ΔTi = 15÷40°C), shortening of the sample warm-up time to the ignition point (Δte = 6÷12 min) and reduction of the sample burning time (Δtf = 40÷54 min). The following series of additives activity affecting ignition temperature of coals has been established: Cu(CH3COO)2 > Cu(NO3)2 > CuSO4. Additionally, the opposite can be said about the effect of additives on residence time of the sample in its combustion area (CuSO4 > Cu(NO3)2 > Cu(CH3COO)2). According to mass spectrometric analysis, presence of NOx, SO2, CO2 (intense peaks at 190÷290°C) was recorded in oxidation products of modified samples, which is explained by partial or complete decomposition of salts.

This prospective study assesses the roles of illness beliefs, emotion regulation factors, and sociodemographic characteristics in decisions to participate in a group support program for women recently diagnosed with breast cancer. Women recruited during clinic visits 2 to 4 weeks after diagnosis completed measures of affective and cognitive factors identified by Leventhal's Common-Sense Model of illness self-regulation: cancer-related distress, avoidance tendencies, beliefs that the breast cancer was caused by stress and altered immunity, and personal control beliefs. Measures of general anxiety and depression, social support, and demographic characteristics were also completed; prognostic status information was obtained from medical records. All women were encouraged to participate in a free, 12-week program offering coping skills training and group support. Participation was recorded by program staff. Of the 110 women, 54 (49%) participated in the group support program and 56 (51%) did not. Logistic regression analyses revealed that participation was predicted by stronger beliefs that the cancer was caused by altered immunity, higher cancer-related distress, lower avoidance tendencies, and younger age. Participation in the group psychosocial support program appeared to be guided by cognitive and affective factors identified by the Common-Sense Model. Psychosocial support programs and informational materials promoting their use may attract more participants if they are tailored to focus on resolving cancer-related distress rather than on general anxiety or depression, appeal to those with high avoidance tendencies, address the role of immune function in cancer progression, and meet the needs of older participants.

Reactions to emotional cues, termed affective reactivity, promote adaptation and survival. Shifts in affective reactivity during pregnancy and postpartum may invoke altered responses to environmental and biological changes. The development and testing of affective reactivity tasks, with published normative ratings for use in studies of affective reactivity, has been based on responses provided by healthy college students. A comparison of the healthy norms with ratings provided by peripartum women has yet to be conducted, despite its value in highlighting critical differences in affective reactivity during peripartum phases. This study compared arousal ratings of unpleasant, neutral, pleasant, and threat stimuli from the International Affective Picture System (IAPS; Lang, P.J., Bradley, M.M., Cuthbert, B.N. 2008. International Affective Picture System (IAPS): Affective Ratings of Pictures and Instruction Manual (Technical Report A-8). University of Florida, Gainseville, FL.) between three samples: (a) women measured during pregnancy and again at postpartum, (b) age-matched nonpregnant women, and (c) college-aged women from the normative sample used to test the stimuli. Using mixed-design GLMs, results showed that the pregnant and postpartum women and the age-matched women showed suppressed arousal relative to the college-age women. Additionally, postpartum women showed increased arousal to unpleasant/threat images compared to other types of images. The data suggest that future research on peripartum women should include affective reactivity tasks based on norms reflective of this specific population. Copyright © 2015 Elsevier Ireland Ltd.

Fanconi anemia core complex gene promoters harbor conserved transcription regulatory elements.

Meier, Daniel; Schindler, Detlev

2011-01-01

The Fanconi anemia (FA) gene family is a recent addition to the complex network of proteins that respond to and repair certain types of DNA damage in the human genome. Since little is known about the regulation of this novel group of genes at the DNA level, we characterized the promoters of the eight genes (FANCA, B, C, E, F, G, L and M) that compose the FA core complex. The promoters of these genes show the characteristic attributes of housekeeping genes, such as a high GC content and CpG islands, a lack of TATA boxes and a low conservation. The promoters functioned in a monodirectional way and were, in their most active regions, comparable in strength to the SV40 promoter in our reporter plasmids. They were also marked by a distinctive transcriptional start site (TSS). In the 5' region of each promoter, we identified a region that was able to negatively regulate the promoter activity in HeLa and HEK 293 cells in isolation. The central and 3' regions of the promoter sequences harbor binding sites for several common and rare transcription factors, including STAT, SMAD, E2F, AP1 and YY1, which indicates that there may be cross-connections to several established regulatory pathways. Electrophoretic mobility shift assays and siRNA experiments confirmed the shared regulatory responses between the prominent members of the TGF-β and JAK/STAT pathways and members of the FA core complex. Although the promoters are not well conserved, they share region and sequence specific regulatory motifs and transcription factor binding sites (TBFs), and we identified a bi-partite nature to these promoters. These results support a hypothesis based on the co-evolution of the FA core complex genes that was expanded to include their promoters.

2004-07-01

Flows in T-junction piping system with turbulence promoter have been investigated experimentally using flow visualization techniques (the dye injection method) and velocity measurement by LDV. Effects of turbulent promoter on characteristics of fluid mixing and thermal-striping phenomena are examined. From the experiment, following results are obtained. (1) Arch vortex is formed further than the case without promoter in the upstream station and is rapidly transported to the downstream direction. (2) Secondary flow induced in the cross section become stronger and the diffusion of axial momentum is promoted, as the height of turbulence promoter is higher. (3) Main flow deflects towards to the opposite side of branch pipe at the T-junction, as the height of turbulence promoter is higher, and as velocity ratio becomes smaller, and the flow continues to deflect to a considerably downstream station. (4) Velocity fluctuation is observed in the position where the vortex is formed, and it becomes a maximum at z/Dm=2. In the further downstream, velocity fluctuation decreases with the vortex breakdown, and it considerably remains to the downstream. (author)

Production of useful chemicals by industrial microorganisms has been attracting more and more attention. Microorganisms screened from their natural environment usually suffer from low productivity, low stress resistance, and accumulation of by-products. In order to overcome these disadvantages, rational engineering of microorganisms to achieve specific industrial goals has become routine. Rapid development of metabolic engineering and synthetic biology strategies provide novel methods to improve the performance of industrial microorganisms. Rational regulation of gene expression by specific promoters is essential to engineer industrial microorganisms for high-efficiency production of target chemicals. Identification, modification, and application of suitable promoters could provide powerful switches at the transcriptional level for fine-tuning of a single gene or a group of genes, which are essential for the reconstruction of pathways. In this review, the characteristics of promoters from eukaryotic, prokaryotic, and archaea microorganisms are briefly introduced. Identification of promoters based on both traditional biochemical and systems biology routes are summarized. Besides rational modification, de novo design of promoters to achieve gradient, dynamic, and logic gate regulation are also introduced. Furthermore, flexible application of static and dynamic promoters for the rational engineering of industrial microorganisms is highlighted. From the perspective of powerful promoters in industrial microorganisms, this review will provide an extensive description of how to regulate gene expression in industrial microorganisms to achieve more useful goals.

The moderation analyses showed, for example, that for individuals with a self-destructive profile, psychological well-being was significantly predicted by the past negative, present fatalistic and future time perspectives. Among individuals with a high affective or a self-fulfilling profile, psychological well-being was significantly predicted by the present fatalistic dimension. Conclusions. The interactions found here go beyond the postulation of a “balanced” time perspective being the only way to promote well-being. Instead, we present a more person-centered approach to achieve higher levels of emotional, cognitive, and psychological well-being. PMID:27019786

French bio-diesel demand and promoting measures analysis by 2010; Analyse de la demande et des mesures de promotion francaises du biodiesel a l'horizon 2010

Energy Technology Data Exchange (ETDEWEB)

Bernard, F

2008-02-15

The researches presented aim at assessing bio-diesel promoting measures under consideration in France by 2010. This assessment is based on a deep study of French bio-diesel demand. The use of a linear model for optimizing the whole French refining industry costs allow us to take into account the physicochemical characteristics of bio-diesel useful for gas oil blending operation. This researches show that bio-diesel can be incorporated up to 27% blend in volume to diesel fuel without major technical problem. A decomposition of the value allotted to the bio-diesel by French refiners according to its physicochemical characteristics shows that energy content is the most disadvantageous characteristics for bio-diesel incorporation and, up to 17%, density become also constraining. However, the low bio-diesel sulphur content could become interesting from now to 2010. On the basis of this bio-diesel demand analysis, we proceed to an external coupling of an agro-industrial model of bio-diesel supply with the French refining model. Thus, we study the impact of the 2010 French bio-diesel consumption objective on agricultural surface need, the competitiveness of the bio-diesel, the reduction of greenhouse gases emissions and the trade balance of the petroleum products. On this basis, we propose a critical analysis of French bio-diesel promoting measures under consideration by 2010. (author)

Structural and Interpersonal Characteristics of Family Meals: Associations with Adolescent BMI and Dietary Patterns

The last decade of research has suggested that family meals play an important role in promoting healthful dietary intake in youth. However, little is known about the structural characteristics and interpersonal dynamics of family meals that may help to inform why family meals are protective for youth. The current mixed methods, cross-sectional study conducted in 2010–2011 includes adolescents and parents who participated in two linked population-based studies. Participants included 40 parents (91.5% female) and adolescents (57.5% female) from the Minneapolis/St. Paul area participating in EAT 2010 and F-EAT. The structural (e.g. length of the meal, types of foods served) and interpersonal characteristics (e.g., communication, emotion/affect management) of family meals were described and associations between interpersonal dynamics at family meals and adolescent body mass index (BMI) and dietary intake were examined via direct observational methods. Families were video-recorded during two mealtimes in their homes. Results indicated that family meals were approximately 20 minutes in length, included multiple family members, were typically served family style (70%) and occurred in the kitchen 62% of the time and 38% of the time in another room (e.g., family room, office). Additionally, significant associations were found between positive interpersonal dynamics (i.e., communication, affect management, interpersonal involvement, overall family functioning) at family meals and lower adolescent BMI and higher vegetable intake. These findings add to the growing body of literature on family meals by providing a better understanding of what is happening at family meals in order to inform obesity prevention studies and recommendations for providers working with families of youth.

A parasitic selfish gene that affects host promiscuity.

Science.gov (United States)

Giraldo-Perez, Paulina; Goddard, Matthew R

2013-11-07

Selfish genes demonstrate transmission bias and invade sexual populations despite conferring no benefit to their hosts. While the molecular genetics and evolutionary dynamics of selfish genes are reasonably well characterized, their effects on hosts are not. Homing endonuclease genes (HEGs) are one well-studied family of selfish genes that are assumed to be benign. However, we show that carrying HEGs is costly for Saccharomyces cerevisiae, demonstrating that these genetic elements are not necessarily benign but maybe parasitic. We estimate a selective load of approximately 1-2% in 'natural' niches. The second aspect we examine is the ability of HEGs to affect hosts' sexual behaviour. As all selfish genes critically rely on sex for spread, then any selfish gene correlated with increased host sexuality will enjoy a transmission advantage. While classic parasites are known to manipulate host behaviour, we are not aware of any evidence showing a selfish gene is capable of affecting host promiscuity. The data presented here show a selfish element may increase the propensity of its eukaryote host to undergo sex and along with increased rates of non-Mendelian inheritance, this may counterbalance mitotic selective load and promote spread. Demonstration that selfish genes are correlated with increased promiscuity in eukaryotes connects with ideas suggesting that selfish genes promoted the evolution of sex initially.

Potential Therapeutic Effects of Meditation for Treating Affective Dysregulation

Directory of Open Access Journals (Sweden)

Natalie T. Y. Leung

2014-01-01

Full Text Available Affective dysregulation is at the root of many psychopathologies, including stress induced disorders, anxiety disorders, and depression. The root of these disorders appears to be an attenuated, top-down cognitive control from the prefrontal cortices over the maladaptive subcortical emotional processing. A form of mental training, long-term meditation practice can trigger meditation-specific neuroplastic changes in the brain regions underlying cognitive control and affective regulation, suggesting that meditation can act as a kind of mental exercise to foster affective regulation and possibly a cost-effective intervention in mood disorders. Increasing research has suggested that the cultivation of awareness and acceptance along with a nonjudgmental attitude via meditation promotes adaptive affective regulation. This review examined the concepts of affective regulation and meditation and discussed behavioral and neural evidence of the potential clinical application of meditation. Lately, there has been a growing trend toward incorporating the “mindfulness” component into existing psychotherapeutic treatment. Promising results have been observed thus far. Future studies may consider exploring the possibility of integrating the element of “compassion” into current psychotherapeutic approaches.

DBA/2J Bax+/− mice exhibited complete resistance to nerve damage after 2 weeks (similar to Bax −/− mice, but 129B6 Bax+/− mice exhibited significant cell loss (similar to wild-type mice. The different cell death phenotype was associated with the level of Bax expression, where 129B6 neurons had twice the level of endogenous Bax mRNA and protein as DBA/2J neurons. Sequence analysis of the Bax promoters between these strains revealed a single nucleotide polymorphism (T129B6 to CDBA/2J at position −515. A 1.5- to 2.5-fold increase in transcriptional activity was observed from the 129B6 promoter in transient transfection assays in a variety of cell types, including RGC5 cells derived from rat RGCs. Since this polymorphism occurred in a p53 half-site, we investigated the requirement of p53 for the differential transcriptional activity. Differential transcriptional activity from either 129B6 or DBA/2J Bax promoters were unaffected in p53−/− cells, and addition of exogenous p53 had no further effect on this difference, thus a role for p53 was excluded. Competitive electrophoretic mobility-shift assays identified two DNA-protein complexes that interacted with the polymorphic region. Those forming Complex 1 bound with higher affinity to the 129B6 polymorphic site, suggesting that these proteins probably comprised a transcriptional activator complex. These studies implicated quantitative expression of the Bax gene as playing a possible role in neuronal susceptibility to damaging stimuli.

Recognizing critical mine spoil health characteristics to design ...

Science.gov (United States)

Biochar can be used as an amendment to remediate metal-contaminated mine spoils for improved site phytostabilization. For successful phytostabilization to occur, biochar amendments must improve mine spoil health with respect to plant rooting plus uptake of water and nutrients. An inappropriate biochar may negatively impact plant growth conditions resulting in poor plant establishment and growth. Matching the appropriate biochar for each mine site requires reconnaissance of spoil chemical and physical conditions and then identifying which properties need rectified to promote plant growth. A rectification hierarchy needs to be established with the primary limiting factor being addressed first, then successive limitations addressed simultaneously or thereafter. We posit that spoils at each site will have a unique chemical, physical, and biological signature that will affect plant growth. For example, some spoils may be extremely acidic, possess phytotoxic concentrations of heavy metals, or have physical conditions that limits water storage and root penetration. Quantifying these and other conditions beforehand allows for the production of designer biochar with specific characteristics tailored for specific plant growth deficiencies within each spoil. Additionally, we recommend the use of proximally located, undisturbed soils to establish spoil remediation targets. In our work, we have developed a decision-tree flow-chart that identifies salient chemical,

Theories of music evolution agree that human music has an affective influence on listeners. Tests of non-humans provided little evidence of preferences for human music. However, prosodic features of speech (‘motherese’) influence affective behaviour of non-verbal infants as well as domestic animals, suggesting that features of music can influence the behaviour of non-human species. We incorporated acoustical characteristics of tamarin affiliation vocalizations and tamarin threat vocalizations...

The aim of this research was to determine encapsulation efficiency, loading capacity and controlled release of eugenol loaded chitosan-tpp products which prepared by coaservation method. The characteristic of eugenol-loaded chitosan showed that %EE and % LC increased by increasing the initial eugenol content. The optimum of %EE (72.63%) and %LC (43.96%) were obtained at the ratio of chitosan to eugenol of 1:1.5. The FTIR spectrum showed the characteristic peaks of eugenol appearing on spectrum of eugenol encapsulated and blue-shift in the hydroxyl band from 3425.58 cm-1 in chitosan-tpp to 3417.86 cm-1 and 3394.72 cm-1 in eugenol loaded chitosan-tpp indicating that eugenol was successfully encapsulated. The surface morphologies of freeze-dried particles with the optimum %EE showed that more surface roughness and porosity than plain particles. Furthermore, the in vitro release of particles with minimum and optimum %EE were also investigated in acid (Simulated Gastric Fluid) and base (Simulated Intestinal Fluid) medium at ambient temperature.

Developing language treatments that not only improve trained items but also promote generalization to untrained items is a major focus in aphasia research. This study is a replication and extension of previous work that found that training abstract words in a particular context-category promotes generalization to concrete words but not vice versa (Kiran, Sandberg, & Abbott, 2009). Twelve persons with aphasia (5 female) with varying types and degrees of severity participated in a generative naming treatment based on the complexity account of treatment efficacy (CATE; Thompson, Shapiro, Kiran, & Sobecks, 2003). All participants were trained to generate abstract words in a particular context-category by analyzing the semantic features of the target words. Two other context-categories were used as controls. Ten of the twelve participants improved on the trained abstract words in the trained context-category. Eight of the ten participants who responded to treatment also generalized to concrete words in the same context-category. These results suggest that this treatment is both efficacious and efficient. We discuss possible mechanisms of training and generalization effects. PMID:24805853
