A series of VOR-DME instrument landing approaches was flown in the DC-9 full-workload simulator to compare pilot performance, scan behavior, and workload when using a computer-drum-pointer altimeter (CDPA) and a digital altimeter (DA). Six pilots executed two sets of instrument landing approaches, with a CDPA on one set and a DA on the other set. Pilot scanning parameters, flight performance, and subjective opinion data were evaluated. It is found that the processes of gathering information from the CDPA and the DA are different. The DA requires a higher mental workload than the CDPA for a VOR-DME type landing approach. Mental processing of altitude information after transitioning back to the attitude indicator is more evident with the DA than with the CDPA.

Campo de velocidade peculiar na teoria linear

NASA Astrophysics Data System (ADS)

Pires, N.

2003-08-01

Aglomerados e superaglomerados de galáxias são responsáveis pela chamada velocidade peculiar (movimentos relativos à expansão pura do universo) das galáxias. A amplitude destas perturbações depende da densidade de matéria do universo e do contraste de densidade no interior do volume onde está localizada a galáxia. Em 1980, Peebles introduziu o fator "f", que relaciona a amplitude das perturbações da velocidade com o campo gravitacional peculiar, no contexto da teoria linear. No presente trabalho obtemos uma solução geral analítica para o fator "f" de Peebles do campo de velocidades peculiares, em termos de funções hipergeométricas, válida para qualquer geometria do universo. Como um teste de nossa solução, os resultados encontrados originalmente por Peebles em 1980 e os resultados mais gerais encontrados por O. Lahav e colaboradores em 1991, são reobtidos.

Cavidades reentrantes de nióbio vêm sendo utilizadas pelo grupo Australiano nos transdutores eletromecânicos paramétricos do detector de ondas gravitacionais Niobè. Esses transdutores paramétricos são ativados por um sinal AC na faixa de microondas (banda X), que é modulado pelo sinal mecânico da vibração da antena esférica, com a variação de um parâmetro, que, no caso, é a capacitância da cavidade. Nós estudamos esse tipo de cavidade, com o objetivo de transformá-la de reentrante aberta para reentrante fechada, de forma a utilizá-la nos transdutores paramétricos do detector brasileiro Mario Schenberg. O desempenho do transdutor depende de alguns parâmetros da cavidade, como a sua Figura de Mérito (Q elétrico) e o seu acoplamento elétrico com o circuito externo. Neste trabalho mostramos a medida do Q elétrico como função do acoplamento, do acabamento superficial interno e do vazamento de microondas da cavidade, e mostramos o desempenho esperado para o detector Mario Schenberg usando uma cavidade supercondutora reentrante fechada de nióbio.

Roles of Fragile X Mental Retardation Protein in Dopaminergic Stimulation-induced Synapse-associated Protein Synthesis and Subsequent α-Amino-3-hydroxyl-5-methyl-4-isoxazole-4-propionate (AMPA) Receptor Internalization*

Fragile X syndrome, the most common form of inherited mental retardation, is caused by the absence of the RNA-binding protein fragile X mental retardation protein (FMRP). FMRP regulates local protein synthesis in dendritic spines. Dopamine (DA) is involved in the modulation of synaptic plasticity. Activation of DA receptors can regulate higher brain functions in a protein synthesis-dependent manner. Our recent study has shown that FMRP acts as a key messenger for DA modulation in forebrain neurons. Here, we demonstrate that FMRP is critical for DA D1 receptor-mediated synthesis of synapse-associated protein 90/PSD-95-associated protein 3 (SAPAP3) in the prefrontal cortex (PFC). DA D1 receptor stimulation induced dynamic changes of FMRP phosphorylation. The changes in FMRP phosphorylation temporally correspond with the expression of SAPAP3 after D1 receptor stimulation. Protein phosphatase 2A, ribosomal protein S6 kinase, and mammalian target of rapamycin are the key signaling molecules for FMRP linking DA D1 receptors to SAPAP3. Knockdown of SAPAP3 did not affect surface expression of α-amino-3-hydroxyl-5-methyl-4-isoxazole-4-propionate (AMPA) GluR1 receptors induced by D1 receptor activation but impaired their subsequent internalization in cultured PFC neurons; the subsequent internalization of GluR1 was also impaired in Fmr1 knock-out PFC neurons, suggesting that FMRP may be involved in subsequent internalization of GluR1 through regulating the abundance of SAPAP3 after DA D1 receptor stimulation. Our study thus provides further insights into FMRP involvement in DA modulation and may help to reveal the molecular mechanisms underlying impaired learning and memory in fragile X syndrome.

The intersection between infectious diseases, poverty and mental disease was an important subject to the Brazilian Neuropsychiatry in the early 19th century. José Martins da Cruz Jobim (1802-1878) was engaged in a hygienist approach based on symptomatological and anatomopathological studies. He wrote "Insânia loquaz" (Loquacious insanity), 1831, the first written text about mental illness in Brazil, founded on clinical and pathological data, compatible with tuberculous meningitis. Thus, Jobim deserves the title of the first neuropsychiatrist in Brazil. The authors critically studied the clinical history and the autopsy findings of his cases, and the main health policies at the time.

to examine advanced practice nursing (APN) roles internationally to inform role development in Latin America and the Caribbean to support universal health coverage and universal access to health. we examined literature related to APN roles, their global deployment, and APN effectiveness in relation to universal health coverage and access to health. given evidence of their effectiveness in many countries, APN roles are ideally suited as part of a primary health care workforce strategy in Latin America to enhance universal health coverage and access to health. Brazil, Chile, Colombia, and Mexico are well positioned to build this workforce. Role implementation barriers include lack of role clarity, legislation/regulation, education, funding, and physician resistance. Strong nursing leadership to align APN roles with policy priorities, and to work in partnership with primary care providers and policy makers is needed for successful role implementation. given the diversity of contexts across nations, it is important to systematically assess country and population health needs to introduce the most appropriate complement and mix of APN roles and inform implementation. Successful APN role introduction in Latin America and the Caribbean could provide a roadmap for similar roles in other low/middle income countries. analisar o papel da enfermagem com prática avançada (EPA) a nível internacional para um relatório do seu desenvolvimento na América Latina e no Caribe, para apoiar a cobertura universal de saúde e o acesso universal à saúde. análise da bibliografia relacionada com os papéis da EPA, sua implantação no mundo e a eficácia da EPA em relação à cobertura universal de saúde e acesso à saúde. dada a evidência da sua eficácia em muitos países, as funções da EPA são ideais como parte de uma estratégia de recursos humanos de atenção primária de saúde na América Latina para melhorar a cobertura universal de saúde e o acesso à saúde.

Animal Fun was designed to enhance motor and social development in young children. Its efficacy in improving motor skills was presented previously using a randomised controlled trial and a multivariate nested cohort design. Based on the Environmental Stress Hypothesis, it was argued that the program would also result in positive mental health outcomes, investigated in the current study. Pre-intervention scores were recorded for 511 children aged 4.83-6.17 years (M=5.42, SD=.30). Intervention and control groups were compared 6 months following intervention, and again in their first school year. Changes in teacher-rated prosocial behaviour and total difficulties were assessed using the Strengths and Difficulties Questionnaire, and data analysed using Generalised Linear Mixed Models. There was a significant improvement in prosocial behaviour of children in the intervention group six months after initial testing, which remained at 18-month follow-up. Total difficulties decreased at 6 months for the intervention group, with no change at 18 months. This effect was present only for the hyperactivity/inattention subscale. The only significant change for the control group was an increase in hyperactivity/inattention scores from pre-intervention to 18-month follow-up. The Animal Fun program appears to be effective in improving social and behavioural outcomes. Copyright © 2015 Elsevier B.V. All rights reserved.

Physical activity contributes to children's physical and mental well-being. Research suggests that active free play helps to maintain and increase physical activity in children and also contributes to social and emotional well-being. To date, these studies have focused on Western countries. Thus, this study was conducted to gain insights into the factors of perceptions of fun, barriers, and facilitators affecting active free play from the perspective of Japanese children using focus group interviews. In Japan, 12 focus groups were conducted with 60 children aged 9-11 years. Children's perceptions of fun in active free play were categorized into socializing, achievement, emotions, and freedom. Additionally, active boys' groups were interested in free play and adventure play; girls' groups were interested in free play with less physical movement and challenges; inactive boys' groups were interested in relaxing and competitive play with bodily contact. However, children mentioned that busy schedules, weather, and health-related factors acted as main barriers. Lastly, children noted facilitators include setting schedules, having access to equipment and playgrounds, and holding special events. The findings provide insights into active free play-related factors for active and inactive Japanese children and also clarify the differences between Japanese and Western children. Such findings will contribute to designing interventions to increase active free play. © The Author(s) 2013.

Despite the critical role of the presynaptic dopamine (DA) transporter (DAT, SLC6A3) in DA clearance and psychostimulant responses, evidence that DAT dysfunction supports risk for mental illness is indirect. Recently, we identified a rare, nonsynonymous Slc6a3 variant that produces the DAT substitution Ala559Val in two male siblings who share a diagnosis of attention-deficit hyperactivity disorder (ADHD), with other studies identifying the variant in subjects with bipolar disorder (BPD) and autism spectrum disorder (ASD). Previously, using transfected cell studies, we observed that although DAT Val559 displays normal total and surface DAT protein levels, and normal DA recognition and uptake, the variant transporter exhibits anomalous DA efflux (ADE) and lacks capacity for amphetamine (AMPH)-stimulated DA release. To pursue the significance of these findings in vivo, we engineered DAT Val559 knock-in mice, and here we demonstrate in this model the presence of elevated extracellular DA levels, altered somatodendritic and presynaptic D2 DA receptor (D2R) function, a blunted ability of DA terminals to support depolarization and AMPH-evoked DA release, and disruptions in basal and psychostimulant-evoked locomotor behavior. Together, our studies demonstrate an in vivo functional impact of the DAT Val559 variant, providing support for the ability of DAT dysfunction to impact risk for mental illness.

Background: Coronary artery bypass graft (CABG) is a standard surgical option for patients with diffuse and significant arterial plaque. This procedure, however, is not free of postoperative complications, especially pulmonary and cognitive disorders. Objective: This study aimed at comparing the impact of two different physiotherapy treatment approaches on pulmonary and cognitive function of patients undergoing CABG. Methods: Neuropsychological and pulmonary function tests were applied, prior to and following CABG, to 39 patients randomized into two groups as follows: Group 1 (control) - 20 patients underwent one physiotherapy session daily; and Group 2 (intensive physiotherapy) - 19 patients underwent three physiotherapy sessions daily during the recovery phase at the hospital. Non-paired and paired Student t tests were used to compare continuous variables. Variables without normal distribution were compared between groups by using Mann-Whitney test, and, within the same group at different times, by using Wilcoxon test. The chi-square test assessed differences of categorical variables. Statistical tests with a p value ≤ 0.05 were considered significant. Results: Changes in pulmonary function were not significantly different between the groups. However, while Group 2 patients showed no decline in their neurocognitive function, Group 1 patients showed a decline in their cognitive functions (P ≤ 0.01). Conclusion: Those results highlight the importance of physiotherapy after CABG and support the implementation of multiple sessions per day, providing patients with better psychosocial conditions and less morbidity.Fundamento: A cirurgia de revascularização miocárdica (CRM) é a opção cirúrgica padrão para pacientes com placas arteriais difusas e significativas. Tal procedimento, no entanto, não é desprovido de complicações pós-operatórias, especialmente distúrbios pulmonares e cognitivos. Objetivo: Comparar o impacto de duas abordagens fisioterapêuticas diferentes nas funções pulmonar e cognitiva de pacientes submetidos a CRM. Métodos: Testes de função pulmonar e neuropsicológicos foram aplicados, antes e após CRM, a 39 pacientes randomizados em dois grupos: Grupo 1 - 20 pacientes-controle submetidos a uma sessão de fisioterapia por dia; Grupo 2 - 19 pacientes submetidos a três sessões de fisioterapia por dia durante recuperação no hospital. Testes t de Student pareado e não pareado foram usados para comparar as variáveis contínuas. Variáveis sem distribuição normal foram comparadas entre os grupos usando-se o teste de Mann-Whitney, e, dentro do mesmo grupo em momentos diferentes, usando-se o teste de Wilcoxon. O teste do qui-quadrado avaliou diferenças das variáveis categóricas. Testes estatísticos com p valor ≤ 0,05 foram considerados significativos. Resultados: As alterações da função pulmonar não diferiram significativamente entre os grupos. Entretanto, o mesmo não ocorreu com a função neurocognitiva, que apresentou declínio no Grupo 1, mas não no Grupo 2 (p ≤ 0,01). Conclusão: Tais resultados reforçam a importância da fisioterapia após CRM e da realização de múltiplas sessões por dia, o que oferece aos pacientes melhores condições psicossociais e menos morbidade.

O estudo dos processos de excitação, fotoabsorção e ionização molecular nas nuvens interestelar, permite a análise dos processos químicos, como a formação e destruição de moléculas, até mesmo daquelas que dão origem à vida. Acredita-se que as moléculas como CS2, NH3, CO2 e N2O estão presentes nas nuvens onde são formadas as estrelas e seus sistemas planetários. Estas moléculas são congeladas na superfície de objetos densos, como aqueles encontrados na Nuvem de Oort do nosso Sistema Solar. Quando esses objetos (cometas) desprendem-se dessa região, aproximam-se do Sol, sofrem a interação da radição Ultra Violeta (UV), passam à fase gasosa e são bombardeados por íons e elétrons presentes nos ventos solares. Obtivemos os espectros de fotoabsorção do CS2, NH3 e N2O na faixa do UV, convertendo espectros de Perda de Energia de Elétrons, medidos no menor ângulo de espalhamento e na energia de impacto de 1000 eV. Destes espectros determinamos os valores de força de oscilador (f) e de seção de choque absolutas na faixa de 500 a 2000 Å. Para tal, estudamos e comparamos dois diferentes métodos de conversão. Neste trabalho também geramos muitos dados moleculares como, valores absolutos de seção de choque elástica em função do ângulo de espalhamento e a distribuição de força do oscilador generalizada (df/dE) em função da energia de excitação para diversos ângulos de espalhamento. Comparando nossos espectros de fotoabsorção com o espectro da atmosfera de Júpiter, obtido pelo Telescópio Espacial Hubble, logo após o impacto do cometa Shoemaker-Levy 9, confirmamos a presença do CS2 e da amônia.

To evaluate diaphragmatic mobility in relation to lung function, respiratory muscle strength, dyspnea, and physical activity in daily life (PADL) in patients with COPD. We included 25 patients with COPD, classified according to the Global Initiative for Chronic Obstructive Lung Disease criteria, and 25 healthy individuals. For all of the participants, the following were evaluated: anthropometric variables, spirometric parameters, respiratory muscle strength, diaphragmatic mobility (by X-ray), PADL, and the perception of dyspnea. In the COPD group, diaphragmatic mobility was found to correlate with lung function variables, inspiratory muscle strength, and the perception of dyspnea, whereas it did not correlate with expiratory muscle strength or PADL. In patients with COPD, diaphragmatic mobility seems to be associated with airway obstruction and lung hyperinflation, as well as with ventilatory capacity and the perception of dyspnea, although not with PADL. Avaliar a relação da mobilidade diafragmática com a função pulmonar, força muscular respiratória, dispneia e atividade física de vida diária (AFVD) em pacientes com DPOC. Foram avaliados 25 pacientes com diagnóstico de DPOC, classificados de acordo com critérios da Global Initiative for Chronic Obstructive Lung Disease, e 25 indivíduos saudáveis. Todos foram submetidos às seguintes avaliações: mensuração antropométrica, espirometria, força muscular respiratória, mobilidade diafragmática (por radiografia), AFVD e percepção de dispneia. No grupo DPOC, houve correlações da mobilidade diafragmática com variáveis de função pulmonar, força muscular inspiratória e percepção de dispneia. Não houve correlações da mobilidade diafragmática com força muscular expiratória e AFVD. A mobilidade diafragmática parece estar associada tanto com a obstrução das vias aéreas quanto com a hiperinsuflação pulmonar em pacientes com DPOC, assim como com a capacidade ventilatória e percepção de dispneia, mas não com AFVD.

This study aims to analyze the current status of the mental health care model of the Brazilian Unified Health System, according to its funding, governance processes, and mechanisms of assessment. We have carried out a documentary analysis of the ordinances, technical reports, conference reports, normative resolutions, and decrees from 2009 to 2014. This is a time of consolidation of the psychosocial model, with expansion of the health care network and inversion of the funding for community services with a strong emphasis on the area of crack cocaine and other drugs. Mental health is an underfunded area within the chronically underfunded Brazilian Unified Health System. The governance model constrains the progress of essential services, which creates the need for the incorporation of a process of regionalization of the management. The mechanisms of assessment are not incorporated into the health policy in the bureaucratic field. There is a need to expand the global funding of the area of health, specifically mental health, which has been shown to be a successful policy. The current focus of the policy seems to be archaic in relation to the precepts of the psychosocial model. Mechanisms of assessment need to be expanded. Analisar o estágio atual do modelo de atenção à saúde mental do Sistema Único de Saúde, segundo seu financiamento, processos de governança e mecanismos de avaliação. Foi realizada uma análise documental de portarias, informes técnicos, relatórios de conferência, resoluções e decretos de 2009 a 2014. Trata-se de um momento de consolidação do modelo psicossocial, com ampliação da rede assistencial, inversão de financiamento para serviços comunitários com forte ênfase na área de crack e outras drogas. A saúde mental é uma área subfinanciada dentro do subfinanciamento crônico do Sistema Único de Saúde. O modelo de governança constrange o avanço de serviços essenciais, havendo a necessidade da incorporação de um processo de regionalização da gestão. Os mecanismos avaliativos no campo burocrático se mostram pouco incorporados à política de saúde. É necessário ampliar o financiamento global da saúde e específico da saúde mental, que vem se constituindo como uma política exitosa. O foco atual da política se mostra anacrônico aos preceitos do modelo psicossocial. Aponta-se a necessidade de ampliação de mecanismos avaliativos.

Children with poor motor ability have been found to engage less in physical activities than other children, and a lack of physical activity has been linked to problems such as obesity, lowered bone mineral density and cardiovascular risk factors. Furthermore, if children are confident with their fine and gross motor skills, they are more likely to engage in physical activities such as sports, crafts, dancing and other physical activity programs outside of the school curriculum which are important activities for psychosocial development. The primary objective of this project is to comprehensively evaluate a whole of class physical activity program called Animal Fun designed for Pre-Primary children. This program was designed to improve the child's movement skills, both fine and gross, and their perceptions of their movement ability, promote appropriate social skills and improve social-emotional development. The proposed randomized and controlled trial uses a multivariate nested cohort design to examine the physical (motor coordination) and psychosocial (self perceptions, anxiety, social competence) outcomes of the program. The Animal Fun program is a teacher delivered universal program incorporating animal actions to facilitate motor skill and social skill acquisition and practice. Pre-intervention scores on motor and psychosocial variables for six control schools and six intervention schools will be compared with post-intervention scores (end of Pre-Primary year) and scores taken 12 months later after the children's transition to primary school Year 1. 520 children aged 4.5 to 6 years will be recruited and it is anticipated that 360 children will be retained to the 1 year follow-up. There will be equal numbers of boys and girls. If this program is found to improve the child's motor and psychosocial skills, this will assist in the child's transition into the first year of school. As a result of these changes, it is anticipated that children will have greater enjoyment participating in physical activities which will further promote long term physical and mental health. This trial is registered in the Australian and New Zealand Clinical trials Registry (ACTRN12609000869279).

The purpose of this article is to discuss the use of music (i.e., two original songs, "Neurotransmitter Twitter" and "Parkinson's Shuffle") to teach aspects of psychopharmacology to students in the course Psychiatric/Mental Health Nursing.

Fun activities are commonly sought and highly desired yet their affective side has received little scrutiny. The present research investigated two features of fun in two daily diary studies and one laboratory experiment. First, we examined the affective state associated with fun experiences. Second, we investigated the social context of fun, considering whether shared fun is more enjoyable than solitary fun. Findings from these studies indicated that fun is associated with both high-activation and low-activation positive affects, and that it is enhanced when experienced with others (especially friends). However, social fun was associated with increases in high-activation but not low-activation positive affect, suggesting that social interaction emphasizes energizing affective experiences. We also found that loneliness moderated the latter effects, such that lonely individuals received a weaker boost from shared compared to solitary fun. These results add to what is known about the impact of social contexts on affective experience.

Declining levels of physical fitness in children are linked to an increased risk of developing poor physical and mental health. Physical activity programs for children that involve regular high intensity physical activity, along with muscle and bone strengthening activities, have been identified by the World Health Organisation as a key strategy to reduce the escalating burden of ill health caused by non-communicable diseases. This paper reports the rationale and methods for a school-based intervention designed to improve physical fitness and physical activity levels of Grades 5 and 6 primary school children. Fit-4-Fun is an 8-week multi-component school-based health-related fitness education intervention and will be evaluated using a group randomized controlled trial. Primary schools from the Hunter Region in NSW, Australia, will be invited to participate in the program in 2011 with a target sample size of 128 primary schools children (age 10-13). The Fit-4-Fun program is theoretically grounded and will be implemented applying the Health Promoting Schools framework. Students will participate in weekly curriculum-based health and physical education lessons, daily break-time physical activities during recess and lunch, and will complete an 8-week (3 × per week) home activity program with their parents and/or family members. A battery of six health-related fitness assessments, four days of pedometery-assessed physical activity and a questionnaire, will be administered at baseline, immediate post-intervention (2-months) and at 6-months (from baseline) to determine intervention effects. Details of the methodological aspects of recruitment, inclusion criteria, randomization, intervention program, assessments, process evaluation and statistical analyses are described. The Fit-4-Fun program is an innovative school-based intervention targeting fitness improvements in primary school children. The program will involve a range of evidence-based behaviour change strategies to promote and support physical activity of adequate intensity, duration and type, needed to improve health-related fitness.

Despite knowing that resveratrol has effects on blood vessels, blood pressure and that phytostrogens can also improve the endothelium-dependent relaxation/vasodilation, there are no reports of reveratrol's direct effect on the endothelial function and blood pressure of animals with estrogen deficit (mimicking post-menopausal increased blood pressure). To verify the effect of two different periods of preventive treatment with resveratrol on blood pressure and endothelial function in ovariectomized young adult rats. 3-month old female Wistar rats were used and distributed in 6 groups: intact groups with 60 or 90 days, ovariectomized groups with 60 or 90 days, and ovariectomized treated with resveratrol (10 mg/kg of body weight per day) for 60 or 90 days. The number of days in each group corresponds to the duration of the experimental period. Vascular reactivity study was performed in abdominal aortic rings, systolic blood pressure was measured and serum nitric oxide (NO) concentration was quantified. Ovariectomy induced blood pressure increase 60 and 90 days after surgery, whereas the endothelial function decreased only 90 days after surgery, with no difference in NO concentration among the groups. Only longer treatment (90 days) with resveratrol was able to improve the endothelial function and normalize blood pressure. Our results suggest that 90 days of treatment with resveratrol is able to improve the endothelial function and decrease blood pressure in ovariectomized rats. Apesar de se saber que o resveratrol apresenta efeitos sobre a pressão arterial e os vasos sanguíneos, e que os fitoestrógenos podem melhorar o relaxamento/vasodilatação dependente do endotélio, não há relatos do efeito direto do resveratrol sobre a pressão arterial e a função endotelial em animais com deficiência de estrógeno (mimetizando a pressão arterial aumentada pós-menopausa). Verificar o efeito de dois diferentes períodos de tratamento preventivo com resveratrol sobre a pressão arterial e a função endotelial em ratas adultas jovens ovariectomizadas. Foram utilizadas ratas Wistar com 3 meses de idade, distribuídas em 6 grupos: grupos intactas com 60 ou 90 dias, grupos ovariectomizadas com 60 ou 90 dias, grupos ovariectomizadas e tratadas com resveratrol na dose de 10mg/kg de massa corporal por dia, durante 60 ou 90 dias, sendo o número de dias em cada grupo relativo à duração do período experimental. Foi realizado um estudo de reatividade vascular em anéis da aorta abdominal, mensurada a pressão arterial sistólica e quantificada a concentração sérica de óxido nítrico (NO). A ovariectomia induziu aumento da pressão arterial 60 e 90 dias após a cirurgia, enquanto a função endotelial decaiu apenas após 90 dias, e não houve diferença na concentração de NO entre os grupos. Apenas o tratamento prolongado com resveratrol (90 dias) foi capaz de melhorar a função endotelial e normalizar a pressão arterial. Nossos resultados sugerem que o tratamento por 90 dias com resveratrol é capaz de melhorar a função endotelial e diminuir a pressão sanguínea em ratas ovariectomizadas.

This study uses means-end chain (MEC) techniques to examine the awareness, decision-making procedure, and personal values of the elderly with regard to virtual reality leisure activities. The results of the study show that elderly respondents value virtual reality leisure activities that are fun, safe, and easy. In terms of outcome benefits, elderly respondents value feeling physically and mentally healthy, firsthand experience, and satisfied curiosity. In value terms, elderly respondents hope that their chosen virtual reality leisure activities improve not only their relationships with others, but also their enjoyment, quality of life, and sense of belonging. The results show that, while consumers with different awarenesses of virtual reality leisure activities have different decision-making processes, they share creating "good memories" as the terminal value with the most significant effect. This presents a potential opportunity to promote virtual reality leisure activities. Relevant bodies or enterprises can seek to create good memories in consumers by developing activities that are safe and fun, promote good health, and provide good service, thereby attracting the interest of elderly consumers.

Environmental cues can affect food decisions. There is growing evidence that environmental cues influence how much one consumes. This article demonstrates that environmental cues can similarly impact the healthiness of consumers' food choices. Two field studies examined this effect with consumers of vending machine foods who were exposed to different posters. In field study 1, consumers with a health-evoking nature poster compared to a pleasure-evoking fun fair poster or no poster in their visual sight were more likely to opt for healthy snacks. Consumers were also more likely to buy healthy snacks when primed by an activity poster than when exposed to the fun fair poster. In field study 2, this consumer pattern recurred with a poster of skinny Giacometti sculptures. Overall, the results extend the mainly laboratory-based evidence by demonstrating the health-relevant impact of environmental cues on food decisions in the field. Results are discussed in light of priming literature emphasizing the relevance of preexisting associations, mental concepts and goals. Copyright © 2015 Elsevier Ltd. All rights reserved.

Few individuals in history have exerted so great an influence and made such extensive contributions to so many disciplines as Leonardo da Vinci. Da Vinci's inquisitive, experimental mentality led him to many discoveries, such as spinal cord function and the proper anatomy of several organ systems. Respected not only as an artist but also as an anatomist, he made many significant contributions to the field. This article explores da Vinci's drawings, in relation to the anatomy of the human spine.

Children cite "fun" as the primary reason for participation in organized sport and its absence as the number-one reason for youth sport attrition. Therefore, the purpose of this study was to develop a theoretical framework of fun using a novel mixed-method assessment of participants in sport (FUN MAPS) via concept mapping. Youth soccer players (n = 142), coaches (n = 37), and parents (n = 57) were stratified by age, sex, and competition level and contributed their ideas through (a) qualitative brainstorming, identifying all of the things that make playing sports fun for players; (b) sorting of ideas; and (c) rating each idea on its importance, frequency, and feasibility. The FUN MAPS identify the 4 fundamental tenets of fun in youth sport within 11 fun-dimensions composed of 81 specific fun-determinants, while also establishing the youth sport ethos. The FUN MAPS provide pictorial evidence-based blueprints for the fun integration theory (FIT), which is a multitheoretical, multidimensional, and stakeholder derived framework that can be used to maximize fun for children and adolescents to promote and sustain an active and healthy lifestyle through sport.

This study examines the role of personality (the Big Five dimensions) in attitudes towards fun and levels of experienced fun in the healthcare environment. Our results show that extraversion and agreeableness were positively related to attitudes toward fun. Extraversion and emotional stability (low neuroticism) were positively related to the level of experienced fun. In general, our sample expressed positive attitudes regarding the appropriateness, salience, and consequences of having fun at work. Additionally, those who reported experiencing greater levels of workplace fun had significantly lower emotional exhaustion and emotional dissonance, as well as higher job satisfaction. Implications for healthcare institutions are discussed.

Web-Based Decision Aid to Assist Help-Seeking Choices for Young People Who Self-Harm: Outcomes From a Randomized Controlled Feasibility Trial.

Adolescents who self-harm are often unsure how or where to get help. We developed a Web-based personalized decision aid (DA) designed to support young people in decision making about seeking help for their self-harm. The aim of this study was to evaluate the feasibility and acceptability of the DA intervention and the randomized controlled trial (RCT) in a school setting. We conducted a two-group, single blind, randomized controlled feasibility trial in a school setting. Participants aged 12 to 18 years who reported self-harm in the past 12 months were randomized to either a Web-based DA or to general information about mood and feelings. Feasibility of recruitment, randomization, and follow-up rates were assessed, as was acceptability of the intervention and study procedures. Descriptive data were collected on outcome measures examining decision making and help-seeking behavior. Qualitative interviews were conducted with young people, parents or carers, and staff and subjected to thematic analysis to explore their views of the DA and study processes. Parental consent was a significant barrier to young people participating in the trial, with only 17.87% (208/1164) of parents or guardians who were contacted for consent responding to study invitations. Where parental consent was obtained, we were able to recruit 81.7% (170/208) of young people into the study. Of those young people screened, 13.5% (23/170) had self-harmed in the past year. Ten participants were randomized to receiving the DA, and 13 were randomized to the control group. Four-week follow-up assessments were completed with all participants. The DA had good acceptability, but qualitative interviews suggested that a DA that addressed broader mental health problems such as depression, anxiety, and self-harm may be more beneficial. A broad-based mental health DA addressing a wide range of psychosocial problems may be useful for young people. The requirement for parental consent is a key barrier to intervention research on self-harm in the school setting. Adaptations to the research design and the intervention are needed before generalizable research about DAs can be successfully conducted in a school setting.

This is Not a Game - Social Virtual Worlds, Fun, and Learning

NASA Astrophysics Data System (ADS)

Bell, Mark W.; Smith-Robbins, Sarah; Withnail, Greg

This chapter asks a simple question: what is required to make learning fun in social virtual worlds? Several scholars have connected fun with learning but most of these have centered on the function of games in learning. Studies of learning in massive multiplayer online role playing games connect the game mechanics to how learning occurs. However, few have asked whether learning in a virtual world can be fun if there is no game. In a social virtual world, like Second Life (SL) there are no game mechanics (unlike game worlds like World of Warcraft [WoW]). There are no quests, challenges, rewards or other game elements in SL. So can a virtual world that has no game-content provided be a place where fun learning can take place? We define fun and explore how fun has been related to learning. We explore theories of fun from Koster, Crawford, Csíkszentmihályi and others as well as views of the ways fun is explored as related to the learning experience. With these models in mind, we explore how fun is different in a social virtual world. Drawing on definitions of fun from Castronova and others, we see game structures in virtual worlds may not be needed to have fun. These fun activities include game creation, business interactions, and most importantly, identity play and socialization in a social virtual world. Finally, we propose that if learning is to be successful and fun in a social virtual world it should pay close attention to these two activities.

Neste trabalho é apresentada uma demonstração do uso dos diferentes desenvolvimentos em séries para as equações de perturbação em Mecânica Celeste no marco Hamiltoniano. Em trabalhos clássicos como os de Poincaré (Poincaré, 1893) por exemplo, já esta planteado o uso de potências não inteiras no pequeno parâmetro, o que evidencia a não analiticidade das funções quando uma ressonância ocorre. Nestes trabalhos os desenvolvimentos são na raíz quadrada da massa de Júpiter (o pequeno parâmetro). Mais recentemente (Ferraz-Mello, 1985) outros tipos de desenvolvimentos foram aplicados modificando substancialmente as ordens de grandeza e a velocidade de convergência das séries. Com esta abordagem, os desenvolvimentos foram expressados em termos da raíz cúbica do pequeno parâmetro. Neste trabalho apresentamos um enfoque geral, onde os diferentes tipos de desenvolvimentos em séries de Puiseux (Valiron, 1950) são obtidos a partir da aplicação de Teorema de Preparação de Weierstrass (Goursat, 1916) considerando a equação de Hamilton-Jacobi como uma equação algébrica. Os resultados são aplicados ao problema restrito dos três corpos em ressonância de primeira ordem e, dependendo da grandeza da excentricidade do asteróide em relação à de Júpiter, obtemos os diferentes desenvolvimentos, em raíz quadrada ou raíz cúbica da massa de Júpiter.

Young survivors of cancer often face challenges reintegrating into their schools and communities after treatment. Maintaining a physically active lifestyle is recommended, but finding appropriate exercises that cater to their needs can be difficult. As a result, the pilot fitness program Move4Fun/Move4Fitness was developed. This 12-week basic fitness program teaches young survivors of cancer appropriate exercises and how they can exercise on their own with limited space and equipment. Participants experienced physical and mental transformations demonstrated through weight loss, building of muscle, and increased self-confidence.

Background Decisions on medical treatment setting are perceived as important but often difficult to make for patients with mental disorders. Shared decision-making as a strategy to decrease decisional conflict has been recommended, but is not yet widely implemented. This study aimed to investigate the information needs and the decision-making preferences of patients with mental disorders prior to the decision for a certain treatment setting. The results will serve as a prerequisite for the development of a high-quality patient decision aid (PtDA) regarding the treatment setting decision. Methods We conducted retrospective individual semi-structured interviews with n=24 patients with mental disorders in three psychotherapeutic inpatient care units. The interviews were audiotaped, transcribed, coded, and content-analyzed. Results The majority of the patients wanted to be involved in the decision-making process. They reported high information needs regarding treatment options in order to feel empowered to participate adequately in the decision for a certain treatment setting. However, some patients did not want to participate or receive information, for example, because of their high burden of mental disorder. Whereas the majority were satisfied with the extent they were involved in the decision, few participants felt sufficiently informed about treatment options. Most patients reported that a decision aid regarding an appropriate treatment setting would have been helpful for them. Important information that should be included in a PtDA was general information about mental illness, effective treatment options, specific information about the different treatment settings, and access to treatment. Discussion The identified information and decision-making needs provide a valuable basis for the development of a PtDA aiming to support patients and caregivers regarding the decision for an adequate treatment setting. As preferences for participation vary among patients and also depend on the current mental state, a flexible approach is needed to meet patients’ individual wishes and needs. PMID:29805250

Studies characterizing asthma phenotypes have predominantly included adults or have involved children and adolescents in developed countries. Therefore, their applicability in other populations, such as those of developing countries, remains indeterminate. Our objective was to determine how low-income children and adolescents with asthma in Brazil are distributed across a cluster analysis. We included 306 children and adolescents (6-18 years of age) with a clinical diagnosis of asthma and under medical treatment for at least one year of follow-up. At enrollment, all the patients were clinically stable. For the cluster analysis, we selected 20 variables commonly measured in clinical practice and considered important in defining asthma phenotypes. Variables with high multicollinearity were excluded. A cluster analysis was applied using a twostep agglomerative test and log-likelihood distance measure. Three clusters were defined for our population. Cluster 1 (n = 94) included subjects with normal pulmonary function, mild eosinophil inflammation, few exacerbations, later age at asthma onset, and mild atopy. Cluster 2 (n = 87) included those with normal pulmonary function, a moderate number of exacerbations, early age at asthma onset, more severe eosinophil inflammation, and moderate atopy. Cluster 3 (n = 108) included those with poor pulmonary function, frequent exacerbations, severe eosinophil inflammation, and severe atopy. Asthma was characterized by the presence of atopy, number of exacerbations, and lung function in low-income children and adolescents in Brazil. The many similarities with previous cluster analyses of phenotypes indicate that this approach shows good generalizability. Estudos que caracterizam fenótipos de asma predominantemente incluem adultos ou foram realizados em crianças e adolescentes de países desenvolvidos; portanto, sua aplicabilidade em outras populações, tais como as de países em desenvolvimento, permanece indeterminada. Nosso objetivo foi determinar como crianças e adolescentes asmáticas de baixa renda no Brasil são distribuídos através de uma análise de clusters. Foram incluídos 306 crianças e adolescentes (6-18 anos de idade) com diagnóstico clínico de asma e sob tratamento médico por pelo menos um ano de acompanhamento. No momento da inclusão, todos os pacientes estavam clinicamente estáveis. Vinte variáveis comumente determinadas na prática clínica e consideradas importantes na definição dos fenótipos de asma foram selecionadas para a análise de clusters. As variáveis com alta multicolinearidade foram excluídas. Uma análise de clusters foi realizada utilizando-se um teste aglomerativo em duas etapas e log-likelihood distance measure. Três clusters foram definidos para nossa população. O cluster 1 (n = 94) incluiu indivíduos com função pulmonar normal, inflamação eosinofílica leve, poucas exacerbações, início mais tardio da asma e atopia leve. O cluster 2 (n = 87) incluiu pacientes com função pulmonar normal, número moderado de exacerbações, início precoce da asma, inflamação eosinofílica mais grave e atopia moderada. O cluster 3 (n = 108) incluiu pacientes com função pulmonar ruim, exacerbações frequentes, inflamação eosinofílica e atopia graves. A asma foi caracterizada por presença de atopia, número de exacerbações e função pulmonar em crianças e adolescentes de baixa renda no Brasil. As muitas semelhanças entre esta e outras análises de clusters de fenótipos indicam que essa abordagem apresenta boa generalização.

LinkIT: a ludic elicitation game for eliciting risk perceptions.

PubMed

Cao, Yan; McGill, William L

2013-06-01

The mental models approach, a leading strategy to develop risk communications, involves a time- and labor-intensive interview process and a lengthy questionnaire to elicit group-level risk perceptions. We propose that a similarity ratings approach for structural knowledge elicitation can be adopted to assist the risk mental models approach. The LinkIT game, inspired by games with a purpose (GWAP) technology, is a ludic elicitation tool designed to elicit group understanding of the relations between risk factors in a more enjoyable and productive manner when compared to traditional approaches. That is, consistent with the idea of ludic elicitation, LinkIT was designed to make the elicitation process fun and enjoyable in the hopes of increasing participation and data quality in risk studies. Like the mental models approach, the group mental model obtained via the LinkIT game can hence be generated and represented in a form of influence diagrams. In order to examine the external validity of LinkIT, we conducted a study to compare its performance with respect to a more conventional questionnaire-driven approach. Data analysis results conclude that the two group mental models elicited from the two approaches are similar to an extent. Yet, LinkIT was more productive and enjoyable than the questionnaire. However, participants commented that the current game has some usability concerns. This presentation summarizes the design and evaluation of the LinkIT game and suggests areas for future work. © 2012 Society for Risk Analysis.

Atualmente, a integração de redes neurais com técnicas da Matemática Nebulosa (Fuzzy Sets), tem sido usada robustamente para fazer previsões em vários sistemas físicos. Este trabalho representa uma continuidade da contribuição apresentada anteriormente durante a XXVIIa Reunião Anual da SAB, onde exploramos a aplicação de redes neurais para previsões futuras de séries temporais. Para este, enfatizamos o uso da técnica ANFIS (Adaptative Neuro-Fuzzy Inference System), que consiste em uma rede do tipo back-propagation, onde os dados são processados em uma camada intermediária, tendo numa camada de saída, os dados numéricos. Para que a previsão seja feita com sucesso utilizando-se técnicas matemáticas adequadas, é fundamental a existência de uma série razoavelmente longa de modo que a dinâmica contida nesta possa ser melhor extraída pela rede neural. Nesse sentido, foram utilizados novamente os dados históricos das manchas do Sol (1818-2002) afim de verificar o comportamento futuro da atividade solar (Ciclos de Schawbe) a partir da técnica descrita acima. Previsões realizadas para o ciclo anterior (n.22, máximo de 158,5 em julho de 1989), bem como para o atual (n.23, máximo de 153 em setembro de 2000), apontam valores bastante coerentes com os publicados na literatura, levando em consideração, respectivamente, as barras de erros associadas: 166+/-18 e 160+/-14. Para o próximo ciclo de Schawbe (2006-2017), nossa previsão aponta o valor de 172+/-23 como máximo para o primeiro semestre de 2011 (Abril +/- 3 meses). A ANFIS acompanha de maneira satisfatória o movimento das séries estudadas durante o treinamento e durante a verificação (menor dispersão das funções de pertinência), com erro absoluto inferior a 20 por cento.

The study aims to explore the effect of positive psychological intervention (fun activities combined with positive mental health education) on the well-being, 2-week illness prevalence, and salivary immunoglobulin A of empty nesters. Ninety-two empty nesters were divided into intervention ( n = 49) and control ( n = 43) groups. The empty nesters in the intervention group performed the intervention in addition to routine community activities. The intervention group scored significantly higher on well-being ( p< .05) compared with the control group after intervention. A week after intervention, salivary immunoglobulin A of the intervention group ( p< .05) was higher than that before intervention. Meanwhile, the difference in salivary immunoglobulin A in the control group before and after intervention was not statistically significant. 2-week illness prevalence in both groups did not exhibit a significant difference ( p> .05). Results indicate that positive psychological intervention can effectively increase the well-being and salivary immunoglobulin A of empty nesters and improve their physical and mental health.

It's fun to transcribe with Fun30: A model for nucleosome dynamics during RNA polymerase II-mediated elongation.

PubMed

Lee, Junwoo; Choi, Eun Shik; Lee, Daeyoup

2018-01-01

The ability of elongating RNA polymerase II (RNAPII) to regulate the nucleosome barrier is poorly understood because we do not know enough about the involved factors and we lack a conceptual framework to model this process. Our group recently identified the conserved Fun30/SMARCAD1 family chromatin-remodeling factor, Fun30 Fft3 , as being critical for relieving the nucleosome barrier during RNAPII-mediated elongation, and proposed a model illustrating how Fun30 Fft3 may contribute to nucleosome disassembly during RNAPII-mediated elongation. Here, we present a model that describes nucleosome dynamics during RNAPII-mediated elongation in mathematical terms and addresses the involvement of Fun30 Fft3 in this process.

To investigate the association of intimate partner violence against women reported in the last 12 months and seven years with the incidence of common mental disorders. A prospective cohort study with 390 women from 18 to 49 years, registered in the Family Health Program of the city of Recife, State of Pernambuco; from July 2013 to December 2014. The Self Reporting Questionnaire-20 (SRQ-20) assessed mental health. Intimate partner violence consists of concrete acts of psychological, physical or sexual violence that the partner inflicts on the woman. Poisson regression was used to estimate crude and adjusted relative risks (RR) of the association between common mental disorders and intimate partner violence. The incidence of common mental disorders was 44.6% among women who reported intimate partner violence in the last 12 months and 43.4% among those who reported in the past seven years. Mental disorders remained associated with psychological violence (RR = 3.0; 95%CI 1.9-4.7 and RR = 1.8; 95%CI 1.0-3.7 in the last 12 months, and seven years, respectively), even in the absence of physical or sexual violence. When psychological violence were related to physical or sexual violence, the risk of common mental disorders was even higher, both in the last 12 months (RR = 3.1; 95%CI 2.1-4.7) and in the last seven years (RR = 2.5; 95%CI 1.7-3.8). Intimate partner violence is associated with the incidence of common mental disorders in women. The treatment of the consequences of IPV and support for women in seeking protection for themselves for public services is essential. Investigar a associação da violência por parceiros íntimos relatada contra as mulheres nos últimos 12 meses e últimos sete anos com a incidência dos transtornos mentais comuns. Estudo de coorte prospectivo com 390 mulheres de 18 a 49 anos, cadastradas no Programa Saúde da Família da cidade do Recife, PE, entre julho de 2013 e dezembro de 2014. A saúde mental foi avaliada pelo Self Reporting Questionnaire-20 (SRQ-20). A violência por parceiro íntimo foi definida por atos concretos de violência psicológica, física ou sexual infligidos à mulher pelo parceiro. A regressão de Poisson foi utilizada para estimar os riscos relativos (RR) brutos e ajustados da associação entre transtorno mental comum e violência por parceiro íntimo. A incidência dos transtornos mentais comuns foi de 44,6% entre as mulheres que relataram violência nos últimos 12 meses e de 43,4% nas que relataram violência nos últimos sete anos. Os transtornos mentais mantiveram-se associados à violência psicológica (RR = 3,0; IC95% 1,9-4,7 e RR = 1,8; IC95% 1,0-3,7 nos últimos 12 meses, e sete anos, respectivamente), mesmo na ausência de violência física ou sexual. Quando a violência psicológica esteve combinada com violência física ou sexual, o risco dos transtornos mentais comuns foi ainda mais elevado, tanto nos últimos 12 meses (RR = 3,1; IC95% 2,1-4,7) quanto nos últimos sete anos (RR = 2,5; IC95% 1,7-3,8). A violência por parceiro íntimo está associada à incidência de transtornos mentais comuns nas mulheres. É fundamental o tratamento das consequências da VPI e o apoio às mulheres na busca de proteção para si pelos serviços públicos.

Functions of Fun30 Chromatin Remodeler in Regulating Cellular Resistance to Genotoxic Stress

PubMed Central

Bi, Xin; Yu, Qun; Siler, Jasmine; Li, Chong; Khan, Ali

2015-01-01

The Saccharomyces cerevisiae Fun30 chromatin remodeler has recently been shown to facilitate long-range resection of DNA double strand break (DSB) ends, which proceeds homologous recombination (HR). This is believed to underlie the role of Fun30 in promoting cellular resistance to DSB inducing agent camptothecin. We show here that Fun30 also contributes to cellular resistance to genotoxins methyl methanesulfonate (MMS) and hydroxyurea (HU) that can stall the progression of DNA replication. We present evidence implicating DNA end resection in Fun30-dependent MMS-resistance. On the other hand, we show that Fun30 deletion suppresses the MMS- and HU-sensitivity of cells lacking the Rad5/Mms2/Ubc13-dependent error-free DNA damage tolerance mechanism. This suppression is not the result of a reduction in DNA end resection, and is dependent on the key HR component Rad51. We further show that Fun30 negatively regulates the recovery of rad5Δ mutant from MMS induced G2/M arrest. Therefore, Fun30 has two functions in DNA damage repair: one is the promotion of cellular resistance to genotoxic stress by aiding in DNA end resection, and the other is the negative regulation of a Rad51-dependent, DNA end resection-independent mechanism for countering replicative stress. The latter becomes manifest when Rad5 dependent DNA damage tolerance is impaired. In addition, we find that the putative ubiquitin-binding CUE domain of Fun30 serves to restrict the ability of Fun30 to hinder MMS- and HU-tolerance in the absence of Rad5. PMID:25806814

Neste trabalho apresentamos imagens de alta resolução angular da região HII gigante G333.1-0.4 obtidas através dos filtros J, H e K no telescópio de 4-m do CTIO. Este trabalho faz parte de um estudo de regiões HII gigantes no infravermelho próximo que tem por objetivo estudar a natureza da formação de estrelas massivas e traçar a estrutura espiral de nossa galáxia. Nossa determinação da distância é baseada no método da paralaxe espectroscópica de estrelas OB localizadas na seqüência principal de idade zero (ZAMS) do Diagrama HR. No caso de G333.1-0.4, a magnitude aparente das estrelas localizadas na ZAMS indica que a distância não pode ser maior do que o limite inferior determinado por técnica rádio (2,8 kpc). Resultados semelhantes foram encontrados para regiões estudadas anteriormente, reforçando a idéia de que a taxa de formação estelar na Via Láctea é menor do que o determinado a partir de dados rádio. Nossos resultados mais recentes sobre o conteúdo estelar de G333.1-0.4 revelaram vários objetos que possuem cores bastante avermelhadas (H-K > 2,0). Nós identificamos estes objetos usando os diagramas cor-cor e cor-magnitude dos aglomerados. Estes objetos apresentam um forte excesso em emissão na banda K e possivelmente se tratam de estrelas do tipo OB envolvidas por um disco/envelope circumestelar espesso. O estudo da função de massa inical desta região, em conjunto com resultados de nossos trabalhos anteriores, aponta para uma IMF independente da posição galática. A contagem de estrelas nos fornece um valor para o número de fótons no contínuo de Lyman que corrobora com a afirmação de que G333.1-0.4 se encontra mais próxima da menor distância determinada por rádio.

Abstract Objective To assess physical and mental functional health status as associated with the severity of intimate partner violence (IPV) and perceived danger. Methods Prospective cross-sectional survey of all patients aged 18–55 in an urban emergency department during a convenience sample of shifts. Instruments included the George Washington Universal Violence Prevention Screening protocol, administered by computer during the initial visit, the Short-Form 12 Health Survey (SF-12), the Conflict Tactics Scale (CTS2), and the Revised Danger Assessment (DA), administered by interview at 1 week follow-up. Results In total, 548 (20%) participants screened disclosed IPV victimization. Of those, 216 (40%) completed the follow-up assessment 1 week later. This cohort was 91% African American, 70% single, and 63% female, with a mean age of 35 (SD 10.41). Both physical and mental health functioning scores were lower than normative levels (50) compared with national averages: Physical Component Summary (PCS) scale 43.64 (SD 10.86) and Mental Component Summary (MCS) scale 37.46 (SD 12.29). As physical assault, psychological aggression, and reported injury increased on the CTS2, mental health functioning diminished (p < 0.01). Increased physical assault and psychological aggression were also associated with diminished physical health functioning (p < 0.05). As victim-perceived danger increased on the DA, both physical and mental health functioning decreased (p < 0.01, p < 0.001, respectively). Greater self-advocacy activities were associated with lower mental (but not physical) health functioning as well. Females experienced worsening mental health functioning as both physical assault and psychological aggression increased, whereas male victims experienced worsening mental health functioning only as psychological aggression increased. Conclusions These findings suggest that IPV takes a greater mental than physical toll (for both sexes) and that as IPV severity increases, mental health functioning diminishes and self-advocacy behaviors increase. Additionally, as perceived danger increases, both physical and mental health status worsens. This has important implications for clinicians to assess and consider IPV victims' perceptions of their situations relative to danger, not just the levels of abuse they are experiencing.

A role for Akt and glycogen synthase kinase-3 as integrators of dopamine and serotonin neurotransmission in mental health.

Beaulieu, Jean-Martin

2012-01-01

Mental illnesses, such as bipolar disorder, attention-deficit/hyperactivity disorder, depression and schizophrenia are a major public health concern worldwide. Several pharmacologic agents acting on monoamine neurotransmission are used for the management of these disorders. However, there is still little understanding of the ultimate molecular mechanisms responsible for the therapeutic effects of these drugs or their relations with disease etiology. Here I provide an overview of recent advances on the involvement of the signalling molecules Akt and glycogen synthase kinase-3 (GSK3) in the regulation of behaviour by the monoamine neurotransmitters dopamine (DA) and serotonin (5-HT). I examine the possible participation of these signalling molecules to the effects of antidepressants, lithium and antipsychotics, as well as their possible contribution to mental disorders. Regulation of Akt and GSK3 may constitute an important signalling hub in the subcellular integration of 5-HT and DA neurotransmission. It may also provide a link between the action of these neurotransmitters and gene products, like disrupted in schizophrenia 1 (DISC1) and neuregulin (NRG), that are associated with increased risk for mental disorders. However, changes in Akt and GSK3 signalling are not restricted to a single disorder, and their contribution to specific behavioural symptoms or therapeutic effects may be modulated by broader changes in biologic contexts or signalling landscapes. Understanding these interactions may provide a better understanding of mental illnesses, leading to better efficacy of new therapeutic approaches.

Faced with the long waiting list for a kidney transplant, the use of donors with expanded criteria, like polycystic kidneys, is an option that aims to increase in a short time the supply of kidneys for transplant. This report of two cases of transplants performed from a donor with polycystic kidneys showed promising results, and the receptors evolved with good renal function, serum creatinine measurements within the normal range and with adequate glomerular filtration rate, evaluated over a period of four years post transplant. This fact confirms that the option of using donors with polycystic kidneys is safe and gives good results. Resumo Diante da longa fila de espera por um transplante renal, a utilização de doadores com critério expandido, a exemplo de rins policísticos, torna-se uma opção que visa aumentar a oferta de rins para transplante a curto prazo. O presente relato de dois casos de transplantes realizados a partir de um doador com rins policísticos apresentou resultado promissor, tendo os receptores evoluído com boa função renal, dosagens de creatinina sérica dentro da faixa de normalidade e com taxa de filtração glomerular adequada, avaliados num período de quatro anos pós-transplante. Isto confirma que a opção da utilização de doadores com rins policísticos é segura e apresenta bons resultados.

The effects of chronic achievement motivation and achievement primes on the activation of achievement and fun goals.

Hart, William; Albarracín, Dolores

2009-12-01

This research examined the hypothesis that situational achievement cues can elicit achievement or fun goals depending on chronic differences in achievement motivation. In 4 studies, chronic differences in achievement motivation were measured, and achievement-denoting words were used to influence behavior. The effects of these variables were assessed on self-report inventories, task performance, task resumption following an interruption, and the pursuit of means relevant to achieving or having fun. Findings indicated that achievement priming (vs. control priming) activated a goal to achieve and inhibited a goal to have fun in individuals with chronically high-achievement motivation but activated a goal to have fun and inhibited a goal to achieve in individuals with chronically low-achievement motivation.

Ratos Wistar (idade = 2 meses, peso corporal = 200g) foram divididos em sete grupos (n=6 cada): controle sedentário (C), grupos exercitados (natação) na intensidade leve por 5 (5L), 10 (10L) e 15 minutos (15L), e grupos exercitados em intensidade moderada por 5 (5M), 10 (10M) e 15 minutes (15M). Na intensidade moderada os animais carregaram uma carga de 5% do peso corporal dos mesmos em seus respectivos dorsos. Os monócitos sangüíneos foram avaliados quanto à quantidade e morfologia e os macrófagos peritoneais foram analisados quanto à quantidade e atividade fagocitária. Os dados foram analisados usando ANOVA e Tukey’s post hoc test (p ≤ 0,05). Os grupos de intensidade leve e 5M apresentaram aumento nos níveis dos monócitos quando comparados com o controle. Foi observado aumento na área celular dos monócitos para os grupos 5L, 10L, 5M e 10M; a área nuclear aumentou para os grupos 10L, 5M e 10M em comparação com o controle. Houve aumento nos macrófagos peritoneais para os grupos 15L, 10M, 15M e diminuição no grupo 5M. A capacidade fagocitária dos macrófagos aumentou nos grupos de intensidade leve e para o grupo 10M. O exercício realizado por curtos períodos modulou o número e função dos macrófagos, assim como o número e morfologia dos monócitos, sendo tais alterações dependentes da intensidade. A soma das respostas agudas observadas nesse estudo pode exercer um efeito protetor contra doenças, podendo ser utilizada para a melhora da saúde e qualidade de vida.

To analyze the interaction between the psychosocial aspects of work and the occurrence of common mental disorders among health workers. This is a cross-sectional study conducted with a representative sample of workers of the primary health care of five municipalities of the State of Bahia, Brazil, in 2012. The variable of outcome were the common mental disorders evaluated by the SRQ-20, and the variables of exposure were high demand (high psychological demand and low control over the work) and low social support in the workplace. Interaction was checked by the deviation of the additivity of the effects for the factors studied from the calculation of excess risk from interaction, proportion of cases attributed to interaction, and the synergy index. The global prevalence of common mental disorders was 21%. The group of combined exposure has shown higher magnitude (high demand and low social support), reaching 28% when compared to the 17% in the situation of no exposure (low demand and high social support). The results strengthen the hypothesis of interaction between the factors investigated, directing to the synergy of the effects. Analisar a interação entre aspectos psicossociais do trabalho e a ocorrência de transtornos mentais comuns entre trabalhadores da saúde. Estudo transversal conduzido em amostra representativa de trabalhadores da atenção básica de cinco municípios da Bahia em 2012. As variáveis desfecho foram os transtornos mentais comuns avaliados pelo SRQ-20, as de exposição foram a alta exigência (alta demanda psicológica e baixo controle sobre o próprio trabalho) e o baixo apoio social no trabalho. A interação foi verificada pelo afastamento da aditividade dos efeitos para fatores estudados a partir do cálculo do excesso de risco devido à interação, proporção de casos atribuída à interação e índice de sinergia. A prevalência global de transtornos mentais comuns foi de 21%. Apresentou maior magnitude no grupo de exposição combinada (alta exigência e baixo apoio social), chegando a 28% quando comparada a 17% na situação de nenhuma exposição (baixa exigência e alto apoio social). Os resultados fortalecem a hipótese de interação entre os fatores investigados, com direção para a sinergia dos efeitos.

Sensitivity Analysis of Multidisciplinary Rotorcraft Simulations

2017-01-01

A multidisciplinary sensitivity analysis of rotorcraft simulations involving tightly coupled high-fidelity computational fluid dynamics and comprehensive analysis solvers is presented and evaluated. An unstructured sensitivity-enabled Navier-Stokes solver, FUN3D, and a nonlinear flexible multibody dynamics solver, DYMORE, are coupled to predict the aerodynamic loads and structural responses of helicopter rotor blades. A discretely-consistent adjoint-based sensitivity analysis available in FUN3D provides sensitivities arising from unsteady turbulent flows and unstructured dynamic overset meshes, while a complex-variable approach is used to compute DYMORE structural sensitivities with respect to aerodynamic loads. The multidisciplinary sensitivity analysis is conducted through integrating the sensitivity components from each discipline of the coupled system. Numerical results verify accuracy of the FUN3D/DYMORE system by conducting simulations for a benchmark rotorcraft test model and comparing solutions with established analyses and experimental data. Complex-variable implementation of sensitivity analysis of DYMORE and the coupled FUN3D/DYMORE system is verified by comparing with real-valued analysis and sensitivities. Correctness of adjoint formulations for FUN3D/DYMORE interfaces is verified by comparing adjoint-based and complex-variable sensitivities. Finally, sensitivities of the lift and drag functions obtained by complex-variable FUN3D/DYMORE simulations are compared with sensitivities computed by the multidisciplinary sensitivity analysis, which couples adjoint-based flow and grid sensitivities of FUN3D and FUN3D/DYMORE interfaces with complex-variable sensitivities of DYMORE structural responses.

Fun and enjoyment are recurring themes in physical education literature, although there has been some debate concerning the distinction between the two concepts. Whereas enjoyment is generally regarded as helpful in fostering positive attitudes towards physical education, fun has not always been considered an appropriate outcome of physical…

The FUN of identifying gene function in bacterial pathogens; insights from Salmonella functional genomics.

PubMed

Hammarlöf, Disa L; Canals, Rocío; Hinton, Jay C D

2013-10-01

The availability of thousands of genome sequences of bacterial pathogens poses a particular challenge because each genome contains hundreds of genes of unknown function (FUN). How can we easily discover which FUN genes encode important virulence factors? One solution is to combine two different functional genomic approaches. First, transcriptomics identifies bacterial FUN genes that show differential expression during the process of mammalian infection. Second, global mutagenesis identifies individual FUN genes that the pathogen requires to cause disease. The intersection of these datasets can reveal a small set of candidate genes most likely to encode novel virulence attributes. We demonstrate this approach with the Salmonella infection model, and propose that a similar strategy could be used for other bacterial pathogens. Copyright © 2013 Elsevier Ltd. All rights reserved.

The Effects of Chronic Achievement Motivation and Achievement Primes on the Activation of Achievement and Fun Goals

PubMed Central

Hart, William; Albarracín, Dolores

2013-01-01

This research examined the hypothesis that situational achievement cues can elicit achievement or fun goals depending on chronic differences in achievement motivation. In 4 studies, chronic differences in achievement motivation were measured, and achievement-denoting words were used to influence behavior. The effects of these variables were assessed on self-report inventories, task performance, task resumption following an interruption, and the pursuit of means relevant to achieving or having fun. Findings indicated that achievement priming (vs. control priming) activated a goal to achieve and inhibited a goal to have fun in individuals with chronically high-achievement motivation but activated a goal to have fun and inhibited a goal to achieve in individuals with chronically low-achievement motivation.

How "fun/importance" fit affects performance: relating implicit theories to instructions.

PubMed

Bianco, Amy T; Higgins, E Tory; Klem, Adena

2003-09-01

People experience a regulatory fit when they employ means of goal pursuit that fit their regulatory orientation, and this fit increases motivation that can enhance performance. The present studies extend previous research on regulatory fit to the classic motivational variables of fun and importance. They also examine for the first time the effect on performance of the fit between individuals' implicit theories about a task's fun or importance and their strategic engagement of the task as fun or important as induced by task instructions. In all three studies, task performance was better when the external task instructions "fit" rather than did not fit participants' implicit theory for the task. The implications of these findings for understanding the motivational effects of fun and importance are discussed.

Renewed Search for FUN (Fractionated and Unidentified Nuclear Effects) in Primitive Chondrites

DOE Office of Scientific and Technical Information (OSTI.GOV)

Tollstrup, D L; Wimpenny, J B; Yin, Q -

Ca-Al-rich inclusions (CAIs) found in primitive chondrites record processes and conditions of the earliest solar system as they are the oldest known solid objects formed in the solar system [1,2]. CAIs with fractionation and unidentified nuclear anomalies (FUN CAIs; [3]) are very rare and thusfar found exclusively in CV carbonaceous chondrites (e.g., Allende and Vigarano)[4]. FUN CAIs are characterized by large nucleosynthetic anomalies in several elements (Ca, Ti, Si, Sr, Ba, Nd, and Sm), large mass-dependant isotope fractionation (Mg, Si, and O), and very little initial {sup 26}Al [4,5 and reference therein]. Formation of FUN CAIs by thermal processing ofmore » presolar dust aggregates prior to the injection of {sup 26}Al into the protoplanetary disk has been proposed. More recently [5] proposed that FUN CAIs formed from a protosolar molecular cloud after injection of {sup 26}Al but before {sup 26}Al and {sup 27}Al were completely homogenized. Therefore discovering more FUN CAIs to perform U-Pb and other short-lived chronometric dating will provide key constraints on the age of the solar system, the isotopic composition of the protosolar molecular cloud, the earliest stages of the thermal processing in the solar system and the timing of {sup 26}Al and other short-lived radionuclide injection into the nascent solar system. Most known FUN CAIs were discovered and studied > 30 yr ago, and their isotope ratios determined using thermal ionization mass spectrometry (TIMS). Most of these FUN CAIs were almost or entirely consumed during their respective analyses. [5] recently identified a new FUN CAI (NWA 779 KS-1) based on O and Mg isotope ratios determined by SIMS and MCICPMS, respectively. We have initiated a systematic search for FUN CAIs in primitive chondrites, taking advantage of the large mass-dependant Mg isotope effects known for FUN inclusions with little or no inferred {sup 26}Al. Our strategy is to use newly developed sample cells capable of holding very large slabs of meteorites for laser ablation interfaced with a multicollector inductively coupled plasma mass spectrometry (LA-MC-ICPMS) at UC Davis. Here report the initial findings of our search and describe the instrument setup we use that provides rapid throughput and accurate results.« less

Observação do abrilhantamento de limbo solar e de estruturas filamentares em 48 ghz utilizando a técnica de regularização adaptativa

NASA Astrophysics Data System (ADS)

O radiotelescópio do Itapetinga tem sido utilizado em campanhas de observações de explosões solares gerando um grande número de mapas diários em 48 GHz como sub-produto destas observações. A resolução espacial do telescópio de 14m do Itapetinga nesta freqüência é de aproximadamente dois minutos de arco. Estruturas de interesse para análise da atmosfera solar quiescente tais como os filamentos e o anel de abrilhantamento do limbo são de dimensão angular moderada da ordem ou ligeiramente menores que a resolução do telescópio. É conhecido que a convolução da função de espalhamento do telescópio, PSF (padrão de ganho do feixe) borra as estruturas de dimensão angular abaixo do HPBW (largura a meia potência do feixe) e portanto é comum a busca por técnicas de restauração que eliminem pelo menos em parte este borramento. Estudamos a restauração destas radioimagens usando a técnica de regularização adaptativa e os resultados ressaltam estas estruturas espaciais de pequeno contraste. O algoritmo da regularização adaptativa faz uso de k imagens, chamadas protótipos, obtidas através da variação de parâmetros de um filtro de regularização. Para controle da qualidade da restauração utilizamos uma imagem de alta resolução espacial obtida na linha H-a e a PSF do Itapetinga para borrá-la. Pequenos desvios, entre a PSF utilizada para o borramento e a PSF utilizada na restauração, produziram alguns desvios notáveis na imagem restaurada porém a adição de ruído nas simulações de restauração foram mais influentes no cálculo da rugosidade da imagem e portanto mais limitante para a restauração. Apresentamos como nosso primeiro resultado uma imagem em 48 GHz com a presença clara do abrilhantamento de limbo que não estava evidente na imagem original e traços de estruturas filamentares, porém ainda sem grande evidência.

Saccharomyces cerevisiae samples stained with FUN-1 dye can be stored at -20 degrees C for later observation.

PubMed

Eggleston, M D; Marshall, P A

2007-01-01

FUN-1, a fluorescent vital dye, has been observed to form cylindrical intravacuolar structures within the vacuoles of metabolically active yeast cells. FUN-1 staining, which begins as a diffuse pool of fluorescent cytoplasmic stain, uses an unknown endogenous biochemical processing mechanism to compact and form orange-red cylindrical intravacuolar structures within the cell vacuole. In the clinical setting, FUN-1 is primarily used for identification of fungal infection. FUN-1 is utilized in the laboratory to distinguish between metabolically active and dead fungal cells. Although this stain is useful for distinguishing between live and dead fungal dead cells, few studies have utilized this chemical. This lack of use in the scientific community may be due to the requirement that cells are visualized directly after staining. Thus, it would be of interest to be able to stain cells and store them for later use. Our lab examined the longevity of cylindrical intravacuolar structures in two strains of Saccharomyces cerevisiae stained with FUN-1 and stored at -20 degrees C. We found that cylindrical intravacuolar structures could be reliably observed and imaged utilizing differential interference contrast microscopy and fluorescence microscopy for 21 days. We also observed that cells stained with FUN-1 would resume propagation on yeast extract, peptone, dextrose (YPD) plates after being frozen at -20 degrees C for 21 days. These modifications to the published procedure for FUN-1 dye staining should allow for a more prevalent and less time sensitive use of this important biological tool.

Transforming a conservative company--one laugh at a time.

PubMed

Hudson, K M

2001-01-01

You wouldn't think of Brady Corporation as an obvious place in which to find a fun culture. This traditional Midwestern company, a manufacturer of industrial signs and other identification products, didn't even allow employees to have coffee at their desks until 1989. But when Katherine Hudson became CEO in 1994, she and her executive team determined that injecting some fun into the company's serious culture could create positive effects within the organization and contribute to increased performance and sales. In this article, Hudson distills her approach to overhauling Brady's culture into six principles of serious fun: More people than you might think are comfortable having fun at work; used with an awareness of cultural sensitivities, fun and laughter really are well-understood international languages; humor can help companies get through tough times; fun can be embodied in formal programs; spontaneous efforts at humor can also be effective; and encouraging fun should begin at the top. She richly illustrates each principle with examples. At Brady, getting people to loosen up and enjoy themselves has fostered a company esprit de corps and greater team camaraderie. It has started conversations that have sparked innovation, helped to memorably convey corporate messages to employees, and increased productivity by reducing stress, among other benefits. And the company has doubled its sales and almost tripled its net income and market capitalization over the past seven years. Brady's experience suggests that promoting fun within the workplace can lead not only to a robust corporate culture but also to improved business performance.

FunCoup 3.0: database of genome-wide functional coupling networks

Schmitt, Thomas; Ogris, Christoph; Sonnhammer, Erik L. L.

2014-01-01

We present an update of the FunCoup database (http://FunCoup.sbc.su.se) of functional couplings, or functional associations, between genes and gene products. Identifying these functional couplings is an important step in the understanding of higher level mechanisms performed by complex cellular processes. FunCoup distinguishes between four classes of couplings: participation in the same signaling cascade, participation in the same metabolic process, co-membership in a protein complex and physical interaction. For each of these four classes, several types of experimental and statistical evidence are combined by Bayesian integration to predict genome-wide functional coupling networks. The FunCoup framework has been completely re-implemented to allow for more frequent future updates. It contains many improvements, such as a regularization procedure to automatically downweight redundant evidences and a novel method to incorporate phylogenetic profile similarity. Several datasets have been updated and new data have been added in FunCoup 3.0. Furthermore, we have developed a new Web site, which provides powerful tools to explore the predicted networks and to retrieve detailed information about the data underlying each prediction.

Rihtman, Tanya; Parush, Shula

2014-01-01

OBJECTIVE. Our aim was to generate a Hebrew translation of the Miller Function and Participation Scales (M-FUN) and assess the validity of U.S. norms for Israeli children. METHOD. All components of the M-FUN were translated, and a pilot study revealed a need for further investigation. The Hebrew M-FUN's fine, gross, and visual-motor (VM) components and M-FUN participation questionnaires were administered to 267 Israeli children (128 boys, 139 girls; mean age = 59.21 mo, standard deviation = 17.84). RESULTS. Significant correlations supported construct validity between age and all motor and participation scores as well as age-group differences. Significant differences between the U.S. and Israeli samples were found only for the VM score. Participation and motor scores were significantly correlated. CONCLUSION. Although VM score results should be interpreted with caution, we provide evidence for use of the fine and gross motor norms and the U.S. criterion-referenced participation scores of the M-FUN with Israeli children.

2011-10-01

Caregivers often struggle with food neophobia on the part of young children. This study examined whether labeling novel healthy foods with fun names would increase children's willingness to try those foods and encourage them to eat more of those foods in a child care setting. Thirty-nine toddler and preschool age children (mean age = 3.9 years) were served each of three foods twice, once labeled with a fun name and once with a healthy name. Percentage of the food consumed by each child was recorded. Overall, children ate a greater percentage of the target foods when they were labeled with fun names. Also, a larger percentage of the children tasted the foods when they were labeled with fun names. This simple strategy could be effective for increasing consumption of healthy foods among young children.

Disentangling Fun and Enjoyment in Exergames Using an Expanded Design, Play, Experience Framework: A Narrative Review.

Mellecker, Robin; Lyons, Elizabeth J; Baranowski, Tom

2013-06-01

With exergames (as with physical activity in general), more intense and longer-duration game play should accrue more health benefits. Exergames, however, appear to be played for relatively short durations, often at medium or lower intensities. Ostensibly games are played for fun or enjoyment. Enhancing the fun or enjoyment experienced during exergame play should enhance the intensity and duration of physical activity, and thereby the health benefits. Research, reviewed herein, indicates fun and/or enjoyment in games are inherently laden with psychosocial, physiological, and embodiment substrates. Physical activity may also have separate or closely related psychosocial, physiological, and embodiment enjoyment substrates. Research is needed to integrate these levels of experience and to identify the game mechanics that enhance, and even maximize, the fun or enjoyment experienced in exergames, to thereby increase the health benefit.

Abundâncias de oxigênio e enxofre nas estrelas de tipo solar da vizinhança solar

NASA Astrophysics Data System (ADS)

Requeijo, F.; Porto de Mello, G. F.

2003-08-01

Alguns resultados sugerem que o Sol seja 58% mais abundante em oxigênio que o meio interestelar local. Esta anomalia parece estender-se para o carbono e o criptônio. Entre as possíveis explicações deste fenômeno estão: uma supernova de tipo II que tenha enriquecido a nebulosa protosolar, tornando-a superabundante em oxigênio; um episódio de infall de material pobre em metais sobre o disco Galático, diluindo o meio interestelar local ou uma migração dinâmica do Sol de uma órbita mais interna da Galáxia para sua posição atual. A escolha entre estes cenários exige o conhecimento preciso da abundância solar em relação às anãs G da vizinhança. Neste contexto, o oxigênio e enxofre, são elementos-chave por serem ambos produzidos pelas supernovas de tipo II, devendo portanto possuir o mesmo padrão de abundância. Este projeto visa esclarecer qual a posição do Sol na distribuição local de abundâncias de enxofre e oxigênio para uma amostra de estrelas de tipo solar com idades e metalicidades bem conhecidas. Para tal, analisamos espectros de alta resolução e alta relação sinal-ruído nas regiões espectrais de ll 6300, 7774 (O) e l8695 (S). Para o enxofre encontramos que o Sol parece ser uma estrela típica dentre as da vizinhança, e que este elemento não mostra a sobreabundância para baixas metalicidades, já bem estabelecida para o oxigênio. Discutimos as abundâncias do enxofre no contexto da Evolução Química da Galáxia. Apresentamos resultados preliminares muito precisos para a linha proibida do oxigênio l6300 e comparamos estes com os obtidos para o tripleto em l7774. Quantificamos os efeitos não-ETL presentes no tripleto em função dos parâmetros atmosféricos estelares.

The inclusion of basic education teachers in the survey domain is a controversial issue and fully debated in the academy. The opportunity for a collective work that incorporated school teachers from a public school to a university's group of physics teaching at university allowed us to glimpse the redefinition of the function of a science teacher (a coauthor of this paper) by himself, such that now he includes research on the knowledge construction by students in his teacher practice. The formation of inter-institutional groups for action planning and research in these areas has proved productive for the task of knowledge construction to support educational processes in school, while the university enriches its collection of experiences critically validated, and can consider the results in teachers initial and continued education. The active participation of the teacher in a research group at the university led him to reflect on the possible didactical ways to be described, analyzed and communicated to other teachers. The construction of a pedagogy that took into account the mental models of students on the basic topics of astronomy, and the changes developed resulting from the lessons taught, led to far-reaching consequences on the pedagogy adopted by the teacher, who incorporates now a new vision of science and alternative forms to dialogue with students, essential components for a researcher in Science Education. La inclusión de los maestros de la escuela básica en el universo de la investigación es polémica y está en amplio debate en el mundo académico. La oportunidad de trabajo colectivo de los maestros de una escuela pública en Río de Janeiro con un grupo universitario de enseñanza de la física nos ha permitido vislumbrar la redefinición de la función de un maestro de ciencias (uno de los coautores de este documento) por él mismo, ahora para incluir la investigación sobre la construcción del conocimiento por los alumnos en su práctica como docente. La formación de grupos interinstitucionales para la planificación de la acción y la investigación ha resultado productiva para el trabajo de construcción de conocimiento de apoyo a los procesos educativos en la escuela, mientras que la universidad enriquece su colección de experiencias validadas, considerando los resultados de la educación inicial y continua de maestros. La participación activa del maestro en un grupo de investigación en la universidad lo llevó a reflexiones sobre los posibles caminos didácticos que pueden ser descriptos, analizados y comunicados a los demás docentes. La construcción de una pedagogía propia, que tuvo en cuenta los modelos mentales de los estudiantes sobre los temas básicos de astronomía, y los cambios desarrollados a partir de las lecciones que enseñó, trajeron consecuencias de largo alcance sobre la pedagogía adoptada por el maestro, que ahora incorpora una nueva visión de la ciencia y formas alternativas al diálogo con los estudiantes, los componentes esenciales para un investigador en Educaciónen Ciencias. A inclusão do professor da escola básica no universo da pesquisa é questão controvertida e em pleno debate no meio acadêmico. A oportunidade de trabalho coletivo que incorporou professores de uma escola municipal no Rio de Janeiro a um grupo de ensino de Física da universidade nos possibilitou vislumbrar a ressignificação da função de um professor de Ciências (co-autor deste trabalho) por ele próprio, agora passando a incluir a pesquisa sobre a construção de conhecimento pelos alunos em sua prática como docente. A formação de grupos interinstitucionais para o planejamento de ações e de pesquisas tem-se mostrado produtiva para um trabalho de construção de conhecimentos a fim de subsidiar processos educativos na escola, ao mesmo tempo em que a universidade enriquece seu acervo de experiências validadas criticamente, podendo considerar seus resultados na formação inicial e continuada de professores. A participação ativa do professor num grupo de pesquisa na universidade o levou à reflexão sobre caminhos didáticos possíveis de serem descritos, analisados e comunicados a outros professores. A construção de uma pedagogia própria, levando em conta os modelos mentais dos alunos sobre temas básicos de Astronomia, e as mudanças promovidas a partir das aulas dadas, trouxeram amplas conseqüências sobre a pedagogia adotada pelo professor. Hoje a prática desse professor incorpora uma nova visão de ciência e formas alternativas de dialogar com os alunos, elementos indispensáveis a um pesquisador em Educação em Ciências.

Most biological processes remain only partially characterized with many components still to be identified. Given that a whole genome can usually not be tested in a functional assay, identifying the genes most likely to be of interest is of critical importance to avoid wasting resources. Given a set of known functionally related genes and using a state-of-the-art approach to data integration and mining, our Functional Lists (FUN-L) method provides a ranked list of candidate genes for testing. Validation of predictions from FUN-L with independent RNAi screens confirms that FUN-L-produced lists are enriched in genes with the expected phenotypes.

2003-08-01

Estrelas T Tauri Clássicas são objetos jovens circundados por discos de gás e poeira e que apresentam uma intensa atividade magnética. Seu espectro mostra linhas de emissão alargadas que são razoavelmente reproduzidas nos modelos de acresção magnetosférica. No entanto, o perfil de temperatura dos funis magnéticos é desconhecido. Aquecimento magnético compressional e difusão ambipolar foram considerados para estas estruturas, porém as temperaturas obtidas não são suficientes para explicar as observações. Neste trabalho, examinamos o aquecimento gerado pelo amortecimento de ondas Alfvén através de quatro mecanismos, os amortecimentos não-linear, turbulento, viscoso-resistivo e colisional como função da freqüência da onda. Inicialmente, a temperatura é ajustada para reproduzir as observações e o grau de turbulência requerido para que o mecanismo seja viável é calculado. Os resultados mostram que este é compatível com os dados observacionais. Apresentam-se, também, resultados preliminares do cálculo auto-consistente do perfil de temperatura dos funis, levando-se em conta fontes de aquecimento Alfvênica e fontes de resfriamento.

Development, Verification and Use of Gust Modeling in the NASA Computational Fluid Dynamics Code FUN3D

NASA Technical Reports Server (NTRS)

Bartels, Robert E.

2012-01-01

This paper presents the implementation of gust modeling capability in the CFD code FUN3D. The gust capability is verified by computing the response of an airfoil to a sharp edged gust. This result is compared with the theoretical result. The present simulations will be compared with other CFD gust simulations. This paper also serves as a users manual for FUN3D gust analyses using a variety of gust profiles. Finally, the development of an Auto-Regressive Moving-Average (ARMA) reduced order gust model using a gust with a Gaussian profile in the FUN3D code is presented. ARMA simulated results of a sequence of one-minus-cosine gusts is shown to compare well with the same gust profile computed with FUN3D. Proper Orthogonal Decomposition (POD) is combined with the ARMA modeling technique to predict the time varying pressure coefficient increment distribution due to a novel gust profile. The aeroelastic response of a pitch/plunge airfoil to a gust environment is computed with a reduced order model, and compared with a direct simulation of the system in the FUN3D code. The two results are found to agree very well.

Assessment of FUN-1 vital dye staining: Yeast with a block in the vacuolar sorting pathway have impaired ability to form CIVS when stained with FUN-1 fluorescent dye.

FUN-1 [2-chloro-4-(2,3-dihydro-3-methyl-(benzo-1,3-thiazol-2-yl)-methylidene)-1-phenylquinolinium iodide] is a fluorescent dye used in studies of yeast and other fungi to monitor cell viability in the research lab and to assay for active fungal infection in the clinical setting. When the plasma membrane is intact, fungal cells internalize FUN-1 and the dye is seen as diffuse green cytosolic fluorescence. FUN-1 is then transported to the vacuole in metabolically active wild type cells and subsequently is compacted into fluorescent red cylindrical intravacuolar structures (CIVS) by an unknown transport pathway. This dye is used to determine yeast viability, as only live cells form CIVS. However, in live Saccharomyces cerevisiae with impaired protein sorting to the yeast vacuole, we report decreased to no CIVS formation, depending on the cellular location of the block in the sorting pathway. Cells with a block in vesicle-mediated transport from the Golgi to prevacuolar compartment (PVC) or with a block in recycling from the PVC to the Golgi demonstrate a substantial impairment in CIVS formation. Instead, the FUN-1 dye is seen either in small punctate structures under fluorescence or as diffuse red cytosol under white light. Thus, researchers using FUN-1 should be cognizant of the limitations of this procedure in determining cell viability as there are viable yeast mutants with impaired CIVS formation.

To evaluate the effects of passive inhalation of cigarette smoke on the respiratory system of guinea pigs. Male guinea pigs were divided into two groups: control and passive smoking, the latter being exposed to the smoke of ten cigarettes for 20 min in the morning, afternoon and evening (30 cigarettes/day) for five days. After that period, inflammatory parameters were studied by quantifying mesenteric mast cell degranulation, as well as oxidative stress, in BAL fluid. In addition, we determined MIP, MEP, and mucociliary transport (in vivo), as well as tracheal contractility response (in vitro). In comparison with the control group, the passive smoking group showed a significant increase in mast cell degranulation (19.75 ± 3.77% vs. 42.53 ± 0.42%; p < 0.001) and in the levels of reduced glutathione (293.9 ± 19.21 vs. 723.7 ± 67.43 nM/g of tissue; p < 0.05); as well as a significant reduction in mucociliary clearance (p < 0.05), which caused significant changes in pulmonary function (in MIP and MEP; p < 0.05 for both) and airway hyperreactivity. Passive inhalation of cigarette smoke caused significant increases in mast cell degranulation and oxidative stress. This inflammatory process seems to influence the decrease in mucociliary transport and to cause changes in pulmonary function, leading to tracheal hyperreactivity. Avaliar os efeitos da inalação passiva da fumaça de cigarro no sistema respiratório de cobaias. Foram utilizadas cobaias machos, divididas em dois grupos: controle e tabagismo passivo, esse último exposto à fumaça de dez cigarros por 20 min pela manhã, tarde e noite (30 cigarros/dia) por 5 dias. Após esse período, parâmetros inflamatórios foram estudados através da contagem de degranulação de mastócitos no mesentério e de estresse oxidativo a partir do LBA. Adicionalmente, foram verificadas PImáx, PEmáx, transporte mucociliar (in vivo) e contratilidade traqueal (in vitro). Na comparação com o grupo controle, o grupo tabagismo passivo apresentou um aumento significativo na degranulação de mastócitos (19,75 ± 3,77% vs. 42,53 ± 0,42%; p < 0,001), nos níveis de glutationa reduzida (293,9 ± 19,21 vs. 723,7 ± 67,43 nM/g de tecido; p < 0,05) e uma redução significativa no transporte mucociliar (p < 0,05), provocando alterações significativas na função pulmonar, tanto na PImáx como na PEmáx (p < 0,05 para ambas), e hiper-reatividade nas vias aéreas. A inalação passiva da fumaça de cigarro ocasionou aumentos significativos na degranulação de mastócitos e no estresse oxidativo. Esse processo inflamatório parece ter influenciado a diminuição do transporte mucociliar e causado alterações na função pulmonar, proporcionando um quadro de hiper-reatividade traqueal.

A freestanding multilayer ultrathin nano-membrane (FUN-membrane) with a micro-ring array (MRA) is successfully fabricated through the controllable film deposition. Each micro-ring of FUN-membrane is 3 μm in diameter, 2 μm in height and sub-100 nm in sidewall thickness, demonstrating an ultrahigh sidewall aspect ratio of 20:1. In our strategy, a silica layer (200 nm in thickness), a chromium transition layer (5 nm-thick) and a gold layer (40 nm-thick), were in sequence deposited on patterned photoresist. After removal of the photoresist by lift-off process, a FUN-membrane with MRA was peeled off from the substrate, where the gold layer acted as a protecting layer to prevent the MRA from fracture. The FUN-membrane was then transferred to a flexible polycarbonate (PC) sheet coated with indium tin oxide (ITO) layer, which was then used as a flexible and lightweight cathode. Remarkably, the field emission effect of the fabricated FUN-membrane cathode performs a high field-enhancement factor of 1.2 × 104 and a low turn-on voltage of 2 V/μm, indicating the advantages of the sharp metal edge of MRA. Due to the rational design and material versatility, the FUN-membrane thus could be transferred to either rigid or flexible substrate, even curved surface, such as the skin of bio-robot's arm or leg. Additionally, the FUN-membrane composed of MRA with extremely high aspect ratio of insulator-metal sidewall, also provides potential applications in optical devices, lightweight and flexible display devices, and electronic eye imagers.

A Influência da Escola e da Mídia na Obtenção dos Conhecimentos Astronômicos

2006-08-01

O universo em que vivemos possui segredos jamais imaginados pelo homem, fruto da pequena proporção que ocupamos diante de um cosmos infinito. A astronomia funciona como um instrumento que sacia a sede humana em desvendar esses segredos, estudando as galáxias, quasares, pulsares além da existência de todos os elementos que preenchem o espaço cósmico, o vácuo, não mais vazio como se pensou em outros tempos. A mídia explora esse campo de forma mística e também científica. A difusão adequada e dentro dos padrões educacionais vigentes, de conceitos astronômicos, se faz necessária, devido sua presença nos conteúdos escolares, centros de ciência e na mídia, de modo geral. A reforma do Currículo Básico da Escola Pública da maioria dos Estados brasileiros introduziu conceitos astronômicos desde a pré-escola até o Ensino Médio. Num estudo realizado com 1.032 alunos do Ensino Médio de seis escolas estaduais, revelou-se através da aplicação de um questionário que abordava conheciment os básicos em astronomia, como estes foram adquiridos e qual era a infra-estrutura oferecida pela escola: para 66,2% dos entrevistados o professor já fez alguma apresentação a respeito de astronomia. O presente estudo revelou também que 44,5% dos alunos entrevistados adquiriram seus conhecimentos astronômicos na escola, 28,1% através da televisão e 27,4% afirmaram que seus conhecimentos foram obtidos através de outros tipos de mídia (internet, filmes e revistas). Embora o estudo revele claramente que há certo equilíbrio na forma em que os alunos obtiveram seus conhecimentos astronômicos, a mídia ainda explora e muitas vezes desperta o interesse pela astronomia com assuntos que não fazem parte de nosso cotidiano como, por exemplo, o homem na Lua, os projetos espaciais e a primeira viagem de um astronauta brasileiro no espaço. Porém, em certos casos, a mídia pode promover conhecimentos incompletos ou mesmo equivocados sobre os conceitos que envolvam a astronomia, como por exemplo a propagação do som no vácuo observado na maioria dos filmes de f icção científica ou da existência das estações do ano em função da distância da Terra ao Sol, em conformidade com o questionário aplicado.

Anemia is a common complication and its impact on morbimortality in patients with chronic kidney disease (CKD) is well known. The discovery of hepcidin and its functions has contributed to a better understanding of iron metabolism disorders in CKD anemia. Hepcidin is a peptide mainly produced by hepatocytes and, through a connection with ferroportin, it regulates iron absorption in the duodenum and its release of stock cells. High hepcidin concentrations described in patients with CKD, especially in more advanced stages are attributed to decreased renal excretion and increased production. The elevation of hepcidin has been associated with infection, inflammation, atherosclerosis, insulin resistance and oxidative stress. Some strategies were tested to reduce the effects of hepcidin in patients with CKD, however more studies are necessary to assess the impact of its modulation in the management of anemia in this population. Resumo Anemia é uma complicação frequente e seu impacto na morbimortalidade é bem conhecido em pacientes com doença renal crônica (DRC). A descoberta da hepcidina e de suas funções contribuíram para melhor compreensão dos distúrbios do metabolismo de ferro na anemia da DRC. Hepcidina é um peptídeo produzido principalmente pelos hepatócitos, e através de sua ligação com a ferroportina, regula a absorção de ferro no duodeno e sua liberação das células de estoque. Altas concentrações de hepcidina descritas em pacientes com DRC, principalmente em estádios mais avançados, são atribuídas à diminuição da excreção renal e ao aumento de sua produção. Elevação de hepcidina tem sido associada à ocorrência de infecção, inflamação, aterosclerose, resistência à insulina e estresse oxidativo. Algumas estratégias foram testadas para diminuir os efeitos da hepcidina em pacientes com DRC, entretanto, serão necessários mais estudos para avaliar o impacto de sua modulação no manejo da anemia nessa população.

Massa do gás e das estrelas em aglomerados: eficiência da formação estelar

Os aglomerados de galáxias apresentam um interesse especial para a cosmologia observacional. Eles são as maiores estruturas ligadas pela gravitação no Universo e relaxadas na região central. A comparação entre a massa do gás intra-aglomerado (responsável por ~25% da massa total, inferida a partir de observações em raios-X), a massa contida nas estrelas (i.e., nas galáxias) e a massa total (incluindo a matéria escura não bariônica), nos dá informações importantes sobre os processos de formação e evolução de aglomerados. Por exemplo, a razão entre a massa do gás e a massa total é uma medida da fração de bárions no Universo (razão entre a matéria bariônica e matéria escura) e, utilizando a densidade de bárions predita pela nucleosíntese primordial, podemos deduzir a densidade de matéria escura no Universo (cf. White et al. 1993). O objetivo deste trabalho é obter as razões entre as massas do gás, estelar (contida nas galáxias), e a total (massa dinâmica). As massas do gás e total são obtidas a partir das análises fotométrica e espectroscópica em raios-X enquanto que a massa estelar é obtida pela análise fotométrica das galáxias. Esta análise foi aplicada ao aglomerado Abell 496 observado pelo satélite XMM-Newton. A massa contida nas galáxias foi estimada a partir da função de luminosidade obtida por Durret et al. (2002). Para determinar as massas dinâmica e do gás nos precisamos determinar os perfis radiais de densidade e temperatura. Nós apresentaremos aqui estes resultados e suas implicações na eficiência da formação estelar em Abell 496.

Under a recent collaborative effort between the US Army Aeroflightdynamics Directorate (AFDD) and NASA Langley, NASA's general unstructured CFD solver, FUN3D, was modularized as a CREATE-AV Helios near-body unstructured grid solver. The strategies adopted in Helios/FUN3D integration effort are described. A validation study of the new capability is performed for rotorcraft cases spanning hover prediction, airloads prediction, coupling with computational structural dynamics, counter-rotating dual-rotor configurations, and free-flight trim. The integration of FUN3D, along with the previously integrated NASA OVERFLOW solver, lays the ground for future interaction opportunities where capabilities of one component could be leveraged with those of others in a relatively seamless fashion within CREATE-AV Helios.

2016-09-01

Myocardial infarction is the most significant manifestation of ischemic heart disease and is associated with high morbidity and mortality. Novel strategies targeting at regenerating the injured myocardium have been investigated, including gene therapy, cell therapy, and the use of growth factors. Growth factor therapy has aroused interest in cardiovascular medicine because of the regeneration mechanisms induced by these biomolecules, including angiogenesis, extracellular matrix remodeling, cardiomyocyte proliferation, stem-cell recruitment, and others. Together, these mechanisms promote myocardial repair and improvement of the cardiac function. This review aims to address the strategic role of growth factor therapy in cardiac regeneration, considering its innovative and multifactorial character in myocardial repair after ischemic injury. Different issues will be discussed, with emphasis on the regeneration mechanisms as a potential therapeutic resource mediated by growth factors, and the challenges to make these proteins therapeutically viable in the field of cardiology and regenerative medicine. Resumo O infarto do miocárdio representa a manifestação mais significativa da cardiopatia isquêmica e está associado a elevada morbimortalidade. Novas estratégias vêm sendo investigadas com o intuito de regenerar o miocárdio lesionado, incluindo a terapia gênica, a terapia celular e a utilização de fatores de crescimento. A terapia com fatores de crescimento despertou interesse em medicina cardiovascular, devido aos mecanismos de regeneração induzidos por essas biomoléculas, incluindo angiogênese, remodelamento da matriz extracelular, proliferação de cardiomiócitos e recrutamento de células-tronco, dentre outros. Em conjunto, tais mecanismos promovem a reparação do miocárdio e a melhora da função cardíaca. Esta revisão pretende abordar o papel estratégico da terapia, com fatores de crescimento, para a regeneração cardíaca, considerando seu caráter inovador e multifatorial sobre o reparo do miocárdio após dano isquêmico. Diferentes questões serão discutidas, destacando-se os mecanismos de regeneração como recurso terapêutico potencial mediado por fatores de crescimento e os desafios para tornar essas proteínas terapeuticamente viáveis no âmbito da cardiologia e da medicina regenerativa.

Kids just wanna have fun: Children's experiences of a weight management programme.

2016-05-01

To explore children's accounts of their experiences of the UK's largest childhood obesity programme, MEND (Mind, Exercise, Nutrition...Do it!) (See www.mendprogramme.org). Semi-structured interviews were conducted with children who had completed the MEND obesity programme. Interviews were transcribed verbatim and analysed using Interpretative Phenomenological Analysis (IPA). Fourteen children spanning diverse areas of London comprised this study (eight male, six female), aged between 11 and 14 years and in secondary school. Participants were interviewed a year after completing one of the London-based MEND obesity programmes. This article focuses on the most common and striking theme to emerge from the original dataset (The complete analysis may be found in L. Watson, Unpublished doctoral thesis): Fun. Subthemes were: 'going with the flow'; active participation in activities that led to new experiences ('actually doing it' - seeing the fun side); the importance of others in the experience of fun ('you do games in unity' - 'it's not as fun on your own'). Children have fun when engaged in interactive and varied activities with opportunity for individual feedback and improvement. When designing childhood obesity programmes, conditions that optimise children's experience of fun should be emphasised over didactic and risk-heavy information pertaining to childhood obesity. What is already known on this subject? Continued growth in childhood obesity and its associated health problems, psychological effects, and economic burden make tackling childhood obesity a public health priority. Multicomponent lifestyle interventions to treat childhood obesity within the community have been shown to reduce overweight and obesity from pre- to post-treatment, increase self-esteem, and are found to be acceptable by parents. MEND is the most widely disseminated evidence-based programme of this kind in the United Kingdom. What does this study add? This study is the first qualitative study to explore the child's experience of attending MEND. The post-treatment maintenance period, where most behaviour change is consolidated (or not), is also captured in this study, with children interviewed at least 1 year post-treatment. Findings unearthed an unexpected and strong theme - that of 'fun' - integral to their experience during their time at MEND. Optimizing conditions for fun is imperative to children's (and adults'?) engagement with, and maintenance of, healthy lifestyle activities. © 2015 The British Psychological Society.

Increased dopamine transporter function as a mechanism for dopamine hypoactivity in the adult infralimbic medial prefrontal cortex following adolescent social stress.

Being bullied during adolescence is associated with later mental illnesses characterized by deficits in cognitive tasks mediated by prefrontal cortex (PFC) dopamine (DA). Social defeat of adolescent male rats, as a model of teenage bullying victimization, results in medial PFC (mPFC) dopamine (DA) hypofunction in adulthood that is associated with increased drug seeking and working memory deficits. Increased expression of the DA transporter (DAT) is also seen in the adult infralimbic mPFC following adolescent defeat. We propose the functional consequence of this increased DAT expression is enhanced DA clearance and subsequently decreased infralimbic mPFC DA availability. To test this, in vivo chronoamperometry was used to measure changes in accumulation of the DA signal following DAT blockade, with increased DAT-mediated clearance being reflected by lower DA signal accumulation. Previously defeated rats and controls were pre-treated with the norepinephrine transporter (NET) inhibitor desipramine (20 mg/kg, ip.) to isolate infralimbic mPFC DA clearance to DAT, then administered the selective DAT inhibitor GBR-12909 (20 or 40 mg/kg, sc.). Sole NET inhibition with desipramine produced no differences in DA signal accumulation between defeated rats and controls. However, rats exposed to adolescent social defeat demonstrated decreased DA signal accumulation compared to controls in response to both doses of GBR-12909, indicating greater DAT-mediated clearance of infralimbic mPFC DA. These results suggest that protracted increases in infralimbic mPFC DAT function represent a mechanism by which adolescent social defeat stress produces deficits in adult mPFC DA activity and corresponding behavioral and cognitive dysfunction.

Targeting of the Fun30 nucleosome remodeller by the Dpb11 scaffold facilitates cell cycle-regulated DNA end resection

DNA double strand breaks (DSBs) can be repaired by either recombination-based or direct ligation-based mechanisms. Pathway choice is made at the level of DNA end resection, a nucleolytic processing step, which primes DSBs for repair by recombination. Resection is thus under cell cycle control, but additionally regulated by chromatin and nucleosome remodellers. Here, we show that both layers of control converge in the regulation of resection by the evolutionarily conserved Fun30/SMARCAD1 remodeller. Budding yeast Fun30 and human SMARCAD1 are cell cycle-regulated by interaction with the DSB-localized scaffold protein Dpb11/TOPBP1, respectively. In yeast, this protein assembly additionally comprises the 9-1-1 damage sensor, is involved in localizing Fun30 to damaged chromatin, and thus is required for efficient long-range resection of DSBs. Notably, artificial targeting of Fun30 to DSBs is sufficient to bypass the cell cycle regulation of long-range resection, indicating that chromatin remodelling during resection is underlying DSB repair pathway choice.

Life at Berkeley for the past 57 years involved research on the thermodynamics, kinetics, and spectroscopic properties of RNA to better understand its structures, interactions, and functions. We (myself and all the graduate students and postdocs who shared in the fun) began with dinucleoside phosphates and slowly worked our way up to megadalton-sized RNA molecular motors. We used UV absorption, circular dichroism, circular intensity differential scattering, fluorescence, NMR, and single-molecule methods. We learned a lot and had fun doing it.

Protein expression of targets of the FMRP regulon is altered in brains of subjects with schizophrenia and mood disorders

PubMed Central

Folsom, Timothy D.; Thuras, Paul D.; Fatemi, S. Hossein

2016-01-01

Fragile X mental retardation protein (FMRP) is an RNA binding protein with 842 target mRNAs in mammalian brain. Silencing of the fragile X mental retardation 1 (FMR1) gene leads to loss of expression of FMRP and upregulated metabotropic glutamate receptor 5 (mGluR5) signaling resulting in the multiple physical and cognitive deficits associated with fragile X syndrome (FXS). Reduced FMRP expression has been identified in subjects with autism, schizophrenia, bipolar disorder, and major depression who do not carry the mutation for FMR1. Our laboratory has recently demonstrated altered expression of four downstream targets of FMRP-mGluR5 signaling in brains of subjects with autism: homer 1, amyloid beta A4 precursor protein (APP), ras-related C3 botulinum toxin substrate 1 (RAC1), and striatal-enriched protein tyrosine phosphatase (STEP). In the current study we investigated the expression of the same four proteins in lateral cerebella of subjects with schizophrenia, bipolar disorder, and major depression and in frontal cortex of subjects with schizophrenia and bipolar disorder. In frontal cortex we observed: 1) reduced expression of 120 kDa form of APP in subjects with schizophrenia and bipolar disorder; 2) reduced expression of 61 kDa and 33 kDa forms of STEP in subjects with schizophrenia; 3) reduced expression of 88 kDa form of APP in subjects with bipolar disorder; and 3) trends for reduced expression of 88 kDa form of APP and homer 1 in subjects with schizophrenia and bipolar disorder, respectively. In lateral cerebella there was no group difference, however we observed increased expression of RAC1 in subjects with bipolar disorder, and trends for increased RAC1 in subjects with schizophrenia and major depression. Our results provide further evidence that proteins involved in the FMRP-mGluR5 signaling pathway are altered in schizophrenia and mood disorders. PMID:25956630

Acredita-se que quando duas estrelas de nêutrons coalescem, elas, eventualmente, formam um buraco negro com massa igual a soma das massas dos objetos originais. Durante a formação do buraco negro, o espaço-tempo em torno do sistema sofre perturbações que se propagam na forma de radiação gravitacional. A forma de onda associada a radiação gravitacional, durante este estágio, aproxima-se a uma senóide exponencialmente amortecida. Este tipo de sinal é conhecido como "ringdown", e seu comportamento e parametrização são muito bem conhecidos. Neste trabalho, simulamos computacionalmente sinais provenientes do "ringdown" de buracos negros, com a finalidade de testar o desempenho do detector de ondas gravitacionais Mario Schenberg em observá-los, quando entrar em funcionamento. Este primeiro teste teórico ajudou-nos a criar estratégias de detecção de sinais imersos no ruído instrumental. Calculamos a relação sinal-ruído como uma função da frequência, bem como sua integral dentro da faixa de sensibilidade do detector. Os resultados obtidos mostraram que o detector Schenberg terá sensibilidade suficiente para detectar este tipo de sinal, proveniente de fontes astrofísicas localizadas dentro de um raio de ~100kpc.

Background Adolescents who self-harm are often unsure how or where to get help. We developed a Web-based personalized decision aid (DA) designed to support young people in decision making about seeking help for their self-harm. Objective The aim of this study was to evaluate the feasibility and acceptability of the DA intervention and the randomized controlled trial (RCT) in a school setting. Methods We conducted a two-group, single blind, randomized controlled feasibility trial in a school setting. Participants aged 12 to 18 years who reported self-harm in the past 12 months were randomized to either a Web-based DA or to general information about mood and feelings. Feasibility of recruitment, randomization, and follow-up rates were assessed, as was acceptability of the intervention and study procedures. Descriptive data were collected on outcome measures examining decision making and help-seeking behavior. Qualitative interviews were conducted with young people, parents or carers, and staff and subjected to thematic analysis to explore their views of the DA and study processes. Results Parental consent was a significant barrier to young people participating in the trial, with only 17.87% (208/1164) of parents or guardians who were contacted for consent responding to study invitations. Where parental consent was obtained, we were able to recruit 81.7% (170/208) of young people into the study. Of those young people screened, 13.5% (23/170) had self-harmed in the past year. Ten participants were randomized to receiving the DA, and 13 were randomized to the control group. Four-week follow-up assessments were completed with all participants. The DA had good acceptability, but qualitative interviews suggested that a DA that addressed broader mental health problems such as depression, anxiety, and self-harm may be more beneficial. Conclusions A broad-based mental health DA addressing a wide range of psychosocial problems may be useful for young people. The requirement for parental consent is a key barrier to intervention research on self-harm in the school setting. Adaptations to the research design and the intervention are needed before generalizable research about DAs can be successfully conducted in a school setting.

Literature shows that patients undergoing hemodialysis present poor physical conditioning and low tolerance to exercise. They may also suffer from respiratory dysfunctions. The purpose of this study was to evaluate the effects of neuromuscular electrical stimulation on pulmonary function and functional capacity of patients with chronic kidney disease on hemodialysis. Forty adult patients with chronic kidney disease on hemodialysis were prospectively studied and randomized into two groups (control n = 20 and treatment n = 20). The treatment group underwent bilateral femoral quadriceps muscles electrical stimulation for 30 minutes during hemodialysis, three times per week, for two months. The patients were evaluated by pulmonary function test, maximum respiratory pressures, maximum one-repetition test, and six-minute walk test (6MWT), before and after the treatment protocol. The treatment group presented increased maximum inspiratory (MIP) (p = 0.02) and expiratory pressures (MEP) (p < 0.0001), muscular strength in maximum one-repetition test (p < 0.001), and distance covered in the 6MWT (p = 0.03), and decreased systolic blood pressure (p < 0.001) and respiratory frequency (p < 0.001) when compared with the control group. Electrical neuromuscular stimulation had a positive impact on pulmonary function and functional capacity, leading to better physical performance in patients on hemodialysis. Pacientes submetidos à hemodiálise apresentam baixo condicionamento físico além de serem acometidos por disfunções respiratórias. Objetivamos avaliar os efeitos da estimulação elétrica neuromuscular na função pulmonar e capacidade funcional de pacientes com doença renal crônica em hemodiálise. 40 adultos com doença renal crônica em hemodiálise foram estudados prospectivamente e randomizados em dois grupos (controle n = 20 e tratamento n = 20). O grupo tratamento realizou protocolo com estimulação elétrica neuromuscular em quadríceps femoral por 30 minutos durante a hemodiálise, três vezes por semana, durante dois meses. Todos pacientes realizaram espirometria, pressões respiratórias máximas, teste de uma repetição máxima e teste da caminhada dos seis minutos (TC6), antes e após o período de acompanhamento. O grupo tratamento apresentou aumento da pressão inspiratória máxima com p = 0,02 na comparação entre grupos e p < 0,001 para a pressão máxima expiratória. O teste de uma repetição máxima e a distância percorrida no TC6 apresentaram-se maiores após o protocolo no grupo de tratamento com p < 0,001 e 0,03 respectivamente. Houve diminuição da pressão arterial sistólica (p < 0,001) e frequência respiratória (p < 0,001) após a estimulação elétrica quando comparado ao grupo controle. A estimulação elétrica neuromuscular teve impacto positivo sobre a função pulmonar e a capacidade funcional levando ao melhor desempenho físico em pacientes em hemodiálise.

Wakes, Sarah; Beukes, Amanda

The study reported in this paper adopted a holistic design approach to investigate issues associated with height related playground injuries from a users' perspective. The main objective was to gain an understanding of the relationship between height and fun so as to establish practical guidelines for addressing the causes of height related injuries whilst maintaining the attributes of playground equipment that children find fun and challenging. Results show that, on the one hand, the risk of injury increases when height is coupled with the use of upper body strength and, on the other hand, that coordination is a greater source of fun and challenge than height for children. Accordingly, it is suggested that the level of risk of injury attached to children's playground equipment can be reduced when the use of lower body strength and coordination are combined with lower free fall heights.

The Kilodegree Extremely Little Telescope (KELT) project is a ground-based, wide-field, synoptic sky survey whose primary goal is to discover exoplanets around bright (8 < V < 11) host stars. KELT photometric observations are carried out using two small robotic telescopes: KELT-North in Arizona, operating since 2005; and KELT-South in South Africa, operating since 2009. Once a transit candidate is identified by the survey telescopes, KELT relies on its Follow Up Network (KELT-FUN) of observatories to vet and characterize the systems by obtaining more precise light curves and radial-velocities. KELT-FUN now includes nearly 50 telescopes around the world and the photometric follow-up is carried out by a diverse set of partners at universities, small colleges, high schools, and private amateur facilities, often with the help of students. We describe KELT-FUN operations and announce the discovery of KELT-18b, a strongly-irradiated hot Jupiter orbiting a mid-F star.

Serious videogames use entertainment to teach, train, or change behavior. What began in the 1970s as tentative attempts to create learning software is now a recognized videogame genre and an emerging health science. Although more research is needed, a growing body of literature suggests serious videogames can be effective. Support for serious videogames, however, is not universal. An informal Web search reveals numerous skeptics. Critics question serious videogames' entertainment value and, thus, their viability. "How can serious videogames attract and maintain players," the argument goes, "if they aren't as much fun as commercial titles, or even any fun at all?" This article examines the argument that, to be effective, serious videogames should be overtly fun and comparable to commercial off-the-shelf videogames. It explores differences between game developer- and researcher-led projects and discusses ways serious videogames can avoid boring and alienating players. It concludes that direct comparisons between serious and commercial game entertainment values may be misdirected.

Antecedents of Young Women's Sexual Risk Taking in Tourist Experiences.

PubMed

Berdychevsky, Liza

2015-11-17

The purpose of this phenomenological exploration was to shed light on the constellation of factors anteceding young women's sexual risk taking during their tourist experiences. A total of 15 in-depth interviews (1.5 to 2.5 hours each) with 13 women were conducted and analyzed through the lens of transcendental phenomenology. An analysis of antecedent factors revealed a confluence of sociopersonal characteristics (e.g., sexual definitions, attitudes, double standards, and age) and touristic attributes (e.g., the sense of temporariness/ephemerality, anonymity, and fun-oriented mentality depending on length, destination, and type of tourist experience) that underlie women's proclivity for and perceptions of sexual risk taking in certain travel scenarios. These result in myriad effects on physical, sexual health, sociocultural, mental, and emotional aspects of women's health and well-being. While the sociopersonal antecedents highlight the cross-pollination between sex-related perceptions in everyday life and touristic environments, the touristic antecedents emphasize the uniqueness of tourist experiences as the contexts for sexual risk taking. The findings address an underresearched topic in sex and tourism scholarship and offer implications for health education and intervention programs, pointing to the value of constructing the context-specific and gender-sensitive sexual health messages underpinned by the ideas of women's empowerment and sexual agency.

To analyze whether socioeconomic and clinical aspects and the aspects of healthy life habits are associated with the quality of life of persons living with HIV/AIDS. This is a cross-sectional exploratory quantitative research, with 227 persons living with HIV/AIDS, treated at two hospitals of reference between April 2012 and June 2014. We used structured questionnaires to assess socioeconomic aspects (gender, age, education level, marital status, race, socioeconomic status, dependents on family income, employment relationship), clinical parameters (time of disease diagnosis, use and time of medication, CD4 T-cell count, and viral load), and practice of physical exercise. To assess quality of life, we used the Quality of Life questionnaire (HAT-QoL). For characterization of the socioeconomic and clinical data and domains of quality of life, we conducted a descriptive analysis (simple frequency, averages, and standard deviations). We applied linear regression, following a hierarchical model for each domain of quality of life. The domains that presented lower averages for quality of life were financial concern, concern with confidentiality, general function, and satisfaction with life. We found associations with the variables of socioeconomic status and physical exercise, therapy, and physical exercise for the last two domains, consecutively. The quality of life of persons living with HIV/AIDS shows losses, especially in the financial and confidentiality areas, followed by general function of the body and satisfaction with life, in which socioeconomic and clinical aspects and healthy living habits, such as the practice of physical exercise, are determining factors for this reality. Analisar se aspectos socioeconômicos, clínicos e de hábitos de vida saudável estão associados à qualidade de vida em pessoas vivendo com HIV/aids. Pesquisa quantitativa exploratória de corte transversal, com 227 pessoas vivendo com HIV/aids, atendidos em dois hospitais de referência entre os períodos de abril 2012 a junho de 2014. Foram utilizados questionários estruturados para avaliar aspectos socioeconômicos (sexo, idade, escolaridade, estado civil, cor de pele, status socioeconômico, dependentes da renda familiar, vínculo empregatício), parâmetros clínicos (tempo de diagnóstico da doença, uso e tempo de medicação, contagem de células TCD4 e carga viral) e prática de exercício físico. Para avaliar qualidade de vida, utilizou-se o questionário Quality of Life (HAT-QoL). Para caracterização dos dados socioeconômicos, clínicos e domínios da qualidade de vida, conduzimos análise descritiva (frequência simples, médias e desvios-padrão). Aplicamos regressão linear, seguindo um modelo hierárquico para cada domínio da qualidade de vida. Os domínios que apresentaram menores médias para a qualidade de vida foram preocupação financeira, preocupação com sigilo, função geral e satisfação com a vida. Foram encontradas associações com as variáveis status socioeconômico e exercício físico; terapia; e exercício físico para os dois últimos domínios, consecutivamente. A qualidade de vida de pessoas vivendo com HIV/aids apresentam prejuízos, principalmente nas questões financeiras e de sigilo, seguidos da função geral do corpo e satisfações com a vida, em que os aspectos socioeconômicos, clínicos e hábitos de vida saudável, como a prática de exercício físico, são fatores determinantes para essa realidade.

To understand mental health nursing care based on the concept of the subject of the unconscious proposed by Lacan. A narrative study was carried out with 19 nurses, chosen based on their theoretical approach or referral by other participants, through the snowball sampling technique. The interviews were carried out in person or digitally, and were recorded and fully transcribed. The analysis was carried out based on Freudian and Lacanian psychoanalysis, approaching nursing care as it acts on the body, secretions, and excretions, to distinguish it from the spirit of fineness. Effects on care are discussed, considering the subject of the unconscious with its knowledge, creating unique exits (sinthome). In this situation, professionals are required to abstain from a position of knowing what is better for the Other. This nursing care perspective offers contributions when discussing the centrality of the subject and words in the care process. Compreender o cuidado de enfermagem em saúde mental a partir da concepção de sujeito do inconsciente proposta por Lacan. Pesquisa narrativa, realizada com 19 enfermeiros, determinados por meio de abordagem teórica ou indicação de outro participante, pela técnica de snowball.

Da análise, fundamentada na psicanálise freudiana e lacaniana, tomou-se o cuidado de enfermagem em seus atos sobre o corpo, suas secreções e excreções, para localizá-lo a partir do espírito de fineza. Discutem-se os efeitos para o cuidado quando se considera o sujeito do inconsciente com seu saber construindo saídas únicas - Sinthoma. Essa condição requer do profissional abster-se de uma posição de saber o que é melhor para o outro. Essa perspectiva de cuidado de enfermagem traz contribuições ao problematizar a centralidade do sujeito e da palavra nas práticas de cuidado.

2005-01-01

Members of a protein family normally have a general biochemical function in common, but frequently one or more subgroups have evolved a slightly different function, such as different substrate specificity. It is important to detect such function shifts for a more accurate functional annotation. The FunShift database described here is a compilation of function shift analysis performed between subfamilies in protein families. It consists of two main components: (i) subfamilies derived from protein domain families and (ii) pairwise subfamily comparisons analyzed for function shift. The present release, FunShift 12, was derived from Pfam 12 and consists of 151 934 subfamilies derived from 7300 families. We carried out function shift analysis by two complementary methods on families with up to 500 members. From a total of 179 210 subfamily pairs, 62 384 were predicted to be functionally shifted in 2881 families. Each subfamily pair is provided with a markup of probable functional specificity-determining sites. Tools for searching and exploring the data are provided to make this database a valuable resource for protein function annotation. Knowledge of these functionally important sites will be useful for experimental biologists performing functional mutation studies. FunShift is available at http://FunShift.cgb.ki.se. PMID:15608176

This study provides information on how two standardized measures based on different theoretical frameworks can be used in collecting information on motor development and performance in 4- and 5-year-olds with autism spectrum disorder (ASD). The purpose of the study was to determine the concurrent validity of the Miller Function and Participation Scales (M-FUN) with the Peabody Developmental Motor Scales, Second Edition (PDMS-2) in young children with ASD. The gross motor sections of the PDMS-2 and the M-FUN were administered to 22 children with ASD between the ages of 48 and 71 months. Concurrent validity between overall motor scores and agreement in identification of motor delay were assessed. A very strong correlation (Pearson's r =.851) was found between the M-FUN scale scores and the PDMS-2 gross motor quotients (GMQs). Strong agreement in identification of children with average motor skills and delayed motor skills at 1.5 standard deviations below the mean was also found. This study supports the concurrent validity of the M-FUN with the PDMS-2 for young children with ASD. While both tests provide information regarding motor delay, the M-FUN may provide additional information regarding the neurological profile of the child.

The family context of children with ADHD plays a role in intervention outcomes, especially when parents are involved in treatment. Parental participation in evidence-based treatment for ADHD may play a role in improving their own parenting self-efficacy (PSE) as well as child outcomes. This study examined the impact of Cognitive-Functional (Cog-Fun) intervention in occupational therapy (OT) for school-aged children with ADHD, on PSE. In this randomized controlled trial with crossover design, 107 children were allocated to intervention and waitlist control groups. Intervention participants (n = 50) received Cog-Fun after baseline assessment and waitlist controls (n = 49) received treatment 3 months later. Intervention participants received 3-month follow-up assessment. Treatment included 10 parent-child Cog-Fun weekly sessions. PSE was assessed with the Tool to measure Parenting Self-Efficacy (TOPSE). All children who began treatment completed it. Mixed ANOVA revealed significant Time x Group interaction effects on TOPSE scales of Play and Enjoyment, Control, Self-Acceptance, Knowledge and Learning and Total score, which showed significant improvement with moderate treatment effects for the intervention group. Results were replicated in the control group after crossover. The findings of this study suggest that Cog-Fun OT intervention may be effective for improving aspects of PSE among parents of children with ADHD.

Calcium-aluminum-rich inclusions with fractionation and unidentified nuclear effects (FUN CAIs): II. Heterogeneities of magnesium isotopes and 26Al in the early Solar System inferred from in situ high-precision magnesium-isotope measurements

Calcium-aluminum-rich inclusions with isotopic mass fractionation effects and unidentified nuclear isotopic anomalies (FUN CAIs) have been studied for more than 40 years, but their origins remain enigmatic. Here we report in situ high precision measurements of aluminum-magnesium isotope systematics of FUN CAIs by secondary ion mass spectrometry (SIMS). Individual minerals were analyzed in six FUN CAIs from the oxidized CV3 carbonaceous chondrites Axtell (compact Type A CAI Axtell 2271) and Allende (Type B CAIs C1 and EK1-4-1, and forsterite-bearing Type B CAIs BG82DH8, CG-14, and TE). Most of these CAIs show evidence for excess 26Mg due to the decay of 26Al. The inferred initial 26Al/27Al ratios [(26Al/27Al)0] and the initial magnesium isotopic compositions (δ26Mg0) calculated using an exponential law with an exponent β of 0.5128 are (3.1 ± 1.6) × 10-6 and 0.60 ± 0.10‰ (Axtell 2271), (3.7 ± 1.5) × 10-6 and -0.20 ± 0.05‰ (BG82DH8), (2.2 ± 1.1) × 10-6 and -0.18 ± 0.05‰ (C1), (2.3 ± 2.4) × 10-5 and -2.23 ± 0.37‰ (EK1-4-1), (1.5 ± 1.1) × 10-5 and -0.42 ± 0.08‰ (CG-14), and (5.3 ± 0.9) × 10-5 and -0.05 ± 0.08‰ (TE) with 2σ uncertainties. We infer that FUN CAIs recorded heterogeneities of magnesium isotopes and 26Al in the CAI-forming region(s). Comparison of 26Al-26Mg systematics, stable isotope (oxygen, magnesium, calcium, and titanium) and trace element studies of FUN and non-FUN igneous CAIs indicates that there is a continuum among these CAI types. Based on these observations and evaporation experiments on CAI-like melts, we propose a generic scenario for the origin of igneous (FUN and non-FUN) CAIs: (i) condensation of isotopically normal solids in an 16O-rich gas of approximately solar composition; (ii) formation of CAI precursors by aggregation of these solids together with variable abundances of isotopically anomalous grains-possible carriers of unidentified nuclear (UN) effects; and (iii) melt evaporation of these precursors accompanied by crystallization under different temperatures and gas pressures, leading to the observed variations in mass-dependent isotopic fractionation (F) effects.

The matrix approach to mental health care: Experiences in Florianopolis, Brazil.

Soares, Susana; de Oliveira, Walter Ferreira

2016-03-01

This article reports on the experience of a matrix approach to mental health in primary health care. Professionals who work in the Family Health Support Nuclei, Núcleos de Apoio à Saúde da Família, pointed to challenges of this approach, especially regarding the difficulties of introducing pedagogic actions in the health field and problems related to work relationships. As the matrix approach and its practice are new aspects of the Brazilian Unified Health System, the academic knowledge must walk hand in hand with everyday professional practice to help improve the quality of the services offered in this context. © The Author(s) 2016.

Immersive virtual reality (VR) distraction provides clinically effective pain relief and increases subjective reports of "fun" in medical settings of procedural pain. The goal of this study was to better describe the variable of "fun" associated with VR distraction analgesia using the circumplex model (pleasure/arousal) of affect. Seventy-four healthy volunteers (mean age, 29 years; 37 females) received a standardized, 18-minute, multimodal pain sequence (alternating thermal heat and electrical stimulation to distal extremities) while receiving immersive, interactive VR distraction. Subjects rated both their subjective pain intensity and fun using 0-10 Graphic Rating Scales, as well as the pleasantness of their emotional valence and their state of arousal on 9-point scales. Compared with pain stimulation in the control (baseline, no VR) condition, immersive VR distraction significantly reduced subjective pain intensity (P < 0.001). During VR distraction, compared with those reporting negative affect, subjects reporting positive affect did so more frequently (41 percent versus 9 percent), as well as reporting both greater pain reduction (22 percent versus 1 percent) and fun scores (7.0 ± 1.9 versus 2.4 ± 1.4). Several factors-lower anxiety, greater fun, greater presence in the VR environment, and positive emotional valence-were associated with subjective analgesia during VR distraction. Immersive VR distraction reduces subjective pain intensity induced by multimodal experimental nociception. Subjects who report less anxiety, more fun, more VR presence, and more positive emotional valence during VR distraction are more likely to report subjective pain reduction. These findings indicate VR distraction analgesia may be mediated through anxiolytic, attentional, and/or affective mechanisms.

The effect of inmates' self-reported childhood and adolescent animal cruelty: motivations on the number of convictions for adult violent interpersonal crimes.

PubMed

Hensley, Christopher; Tallichet, Suzanne E

2008-04-01

Few researchers have investigated the potentially predictive power of motives for childhood and adolescent animal cruelty as it is associated with interpersonal violence in adulthood. Based on a sample of 261 inmates at medium- and maximum-security prisons in a southern state, the present study examines the relationship among several retrospectively reported motives (anger, fun, dislike, and imitation) for animal cruelty and violent crime convictions (assault, rape, and murder). Almost half reported abusing animals out of anger, whereas more than one third did so for fun. Dislike for the animal and imitation were less frequently occurring motives. Participants who abused animals at an earlier age and those who did so out of anger or for fun were more likely to repeat the offense. Regression analyses revealed that abusing an animal out of fun in their youth was the most statistically salient motive for predicting later interpersonal violence as adults.

Emotional disorders (Anxiety disorders and Mood disorders) are one of the most common health problems worldwide, and their economic costs are very high. People suffering from emotional disorders often use maladaptive emotion regulation strategies and have low coping behaviour that contributes to the presence of clinical symptoms. For this reason, it is important to develop strategies to monitor coping and promote emotion regulation in people exposed to high levels of stress. Information and Communication Technologies (ICT) can help us in this task. Recent systematic reviews of literature on evidence-based CBT treatments delivered via the Internet show that these approaches are effective. We have developed an intervention program ICT based: Coping with Stress and Emotion Regulation Program (Smiling is Fun), a self-applied program via the Internet. Smiling is Fun follows a transdiagnostic perspective, and it is based on CBT techniques. However, it also includes other psychological strategies to improve positive mood. The aim of the present work is to describe Smiling is Fun and the study designed to test its efficacy.

FunBlocks. A modular framework for AmI system development.

Baquero, Rafael; Rodríguez, José; Mendoza, Sonia; Decouchant, Dominique; Papis, Alfredo Piero Mateos

2012-01-01

The last decade has seen explosive growth in the technologies required to implement Ambient Intelligence (AmI) systems. Technologies such as facial and speech recognition, home networks, household cleaning robots, to name a few, have become commonplace. However, due to the multidisciplinary nature of AmI systems and the distinct requirements of different user groups, integrating these developments into full-scale systems is not an easy task. In this paper we propose FunBlocks, a minimalist modular framework for the development of AmI systems based on the function module abstraction used in the IEC 61499 standard for distributed control systems. FunBlocks provides a framework for the development of AmI systems through the integration of modules loosely joined by means of an event-driven middleware and a module and sensor/actuator catalog. The modular design of the FunBlocks framework allows the development of AmI systems which can be customized to a wide variety of usage scenarios.

Abstract Serious videogames use entertainment to teach, train, or change behavior. What began in the 1970s as tentative attempts to create learning software is now a recognized videogame genre and an emerging health science. Although more research is needed, a growing body of literature suggests serious videogames can be effective. Support for serious videogames, however, is not universal. An informal Web search reveals numerous skeptics. Critics question serious videogames' entertainment value and, thus, their viability. “How can serious videogames attract and maintain players,” the argument goes, “if they aren't as much fun as commercial titles, or even any fun at all?” This article examines the argument that, to be effective, serious videogames should be overtly fun and comparable to commercial off-the-shelf videogames. It explores differences between game developer- and researcher-led projects and discusses ways serious videogames can avoid boring and alienating players. It concludes that direct comparisons between serious and commercial game entertainment values may be misdirected. PMID:24761316

Subjective well-being refers to people's level of satisfaction with life as a whole and with multiple dimensions within it. Interventions that promote subjective well-being are important because there is evidence that physical health, mental health, substance use, and health care costs may be related to subjective well-being. Fun For Wellness (FFW) is a new online universal intervention designed to promote growth in multiple dimensions of subjective well-being. The purpose of this study was to provide an initial evaluation of the efficacy of FFW to increase subjective well-being in multiple dimensions in a universal sample. The study design was a prospective, double-blind, parallel group randomized controlled trial. Data were collected at baseline and 30 and 60 days-post baseline. A total of 479 adult employees at a major university in the southeast of the USA were enrolled. Recruitment, eligibility verification, and data collection were conducted online. Measures of interpersonal, community, occupational, physical, psychological, economic (i.e., I COPPE), and overall subjective well-being were constructed based on responses to the I COPPE Scale. A two-class linear regression model with complier average causal effect estimation was imposed for each dimension of subjective well-being. Participants who complied with the FFW intervention had significantly higher subjective well-being, as compared to potential compliers in the Usual Care group, in the following dimensions: interpersonal at 60 days, community at 30 and 60 days, psychological at 60 days, and economic at 30 and 60 days. Results from this study provide some initial evidence for both the efficacy of, and possible revisions to, the FFW intervention.

To compare somatic growth, lung function, and level of physical activity in schoolchildren who had been very-low-birth-weight preterm infants (VLBWPIs) or normal-birth-weight full-term infants. We recruited two groups of schoolchildren between 8 and 11 years of age residing in the study catchment area: those who had been VLBWPIs (birth weight < 1,500 g); and those who had been normal-birth-weight full-term infants (controls, birth weight ≥ 2,500 g). Anthropometric and spirometric data were collected from the schoolchildren, who also completed a questionnaire regarding their physical activity. In addition, data regarding the perinatal and neonatal period were collected from the medical records of the VLBWPIs. Of the 93 schoolchildren screened, 48 and 45 were in the VLBWPI and control groups, respectively. No significant differences were found between the groups regarding anthropometric characteristics, nutritional status, or pulmonary function. No associations were found between perinatal/neonatal variables and lung function parameters in the VLBWPI group. Although the difference was not significant, the level of physical activity was slightly higher in the VLBWPI group than in the control group. Among the schoolchildren evaluated here, neither growth nor lung function appear to have been affected by prematurity birth weight, or level of physical activity. Comparar o crescimento somático, a função pulmonar e o nível de atividade física entre escolares nascidos prematuros com muito baixo peso e escolares nascidos a termo e com peso adequado. Foram recrutados escolares com idade de 8 a 11 anos residentes na mesma área de abrangência do estudo: prematuros e com peso < 1.500 g e controles (nascidos a termo e com peso ≥ 2.500 g). Foram obtidas medidas antropométricas e espirométricas e aplicado um questionário sobre a atividade física. Além disso, foram coletadas informações do período perinatal/neonatal dos recém-nascidos com muito baixo peso (RNMBP) de seus prontuários médicos. Dos 93 escolares avaliados, 48 crianças no grupo RNMBP e 45 no grupo controle. Não houve diferenças significativas entre os grupos em relação às características antropométricas e nutricionais ou aos parâmetros de função pulmonar. Não foram encontradas associações entre as variáveis perinatais/neonatais e parâmetros da função pulmonar dos escolares no grupo RNMBP. Embora sem diferença significativa em relação aos níveis de atividade física, o grupo RNMBP apresentou uma tendência de ser mais ativo que o grupo controle. Nos escolares aqui estudados o crescimento e a função pulmonar parecem não ser afetados por prematuridade, peso ao nascimento ou nível de atividade física.

The Brazilian Postgraduate system is divided in two different fields, according to its aspects: the "lato sensu" postgraduate, defined as all professional studies performed after the high school graduation; and the "stricto sensu" postgraduate that includes the master degree and the doctorate, both of them different from what is known as MSc or MS and PhD. The Brazilian doctorate is recognized as academic because its purposes include to improve the scientific and the teaching levels of university docents. The master degree has two different objectives one is to be academic and similar to the doctorate; the other is to upgrade professionals to a higher level than specialist or MBA and is denominated professional master degree. The master degrees and the doctorate are designated as courses and may be put together in a structure known as stricto sensu postgraduate program. The complexity of these courses and programs in all the areas of the superior human knowledge requires a large number of professional directly involved with this system and other professionals that attend them, called consultants and advisors. The consultants are counselors, and the advisors are assistants, both of them legally established with the incumbency to aid the postgraduate staff in all their duties. Nothing prevents a person from being a consultant on the situation and advisor on another, even in the same institution. Have knowledge about what being a consultant and advisor is required to exercise the function within the limits and dimension that the wingspan of the professional allows.

2018-04-01

Previous empirical studies have shown that both spiritual well-being (SWB) and death anxiety (DA) significantly affect the mental health of patients with acute diseases. In this regard, our paper contributes to the extant literature by scrutinizing the conditional relationship between SWB and DA as well as the various mechanisms underpinning such a relationship in patients with acute myocardial infraction (AMI). A descriptive, correlational methodology was utilized. Our main sample consisted of 300 patients with acute myocardial infraction who were hospitalized in a specialized medical institution in Iran throughout a two-month period (i.e. August-October 2015). Patients completed Spiritual Well-Being Scale (SWBS) and Templer's Death Anxiety Scale (TDAS). Even though our study showed that the relationship between SWB and DA in patients with AMI is non-significant, we found that (1) single patients with higher SWB have lower DA, (2) single patients with higher SWB as well as social support have significantly lower DA, and (3) for single men/men without social support, there is a negative relationship between SWB and DA. The relationship between SWB and DA is influenced by factors such as sex, marital status and social support. In addition, the specific nature of this relationship (i.e. strength and sign) is dependent upon the sociodemographic characteristics of patients as well as other contextual influences. Result revealed that although relationship between SWB and DA is non-significant, this is influenced by factors such as sex and social support. In addition, the specific nature of this relationship (i.e. strength and sign) is dependent upon the sociodemographic characteristics of patients as well as other contextual influences.

Physics...fun? 'Physics is Fun' - it's a book, a course, a summer school... Physics, with a reputation for hard maths, nonsensical equations and crazy teachers living with a permanent bad hair day, yes, PHYSICS IS FUN! Maybe if we say it often enough our students will believe us. PHYSICS IS FUN! Keep saying it, and try to believe it. But we are scientists, and we have to look at the evidence and acknowledge the truth: when most people recall the fun times they had at school-how many think about their physics classes? Try asking them. Let's face it - although our students enjoy our exciting demonstrations, the well-structured development of concepts in our classes, and the cooperative and supportive atmosphere of our classrooms and laboratories, even when they find that their physics teachers are the most kind, considerate and approachable of people, even then, when we've done all we can to make physics pleasant, fun and exciting, our students have to fathom out physics... and that can be hard! 'Physics isn't fun in the trivial sense, it's hard work: but you get a fantastic sense of achievement when you make progress.' This is my counsel to most young people who come to discuss whether or not to opt for physics. We try our best to make the material accessible and interesting, but at the end of the day, struggling with something that intially you can't do, but eventually you can do, is part of developing in physics. But what about the teachers? November's meeting of physics teachers from across Europe, Physics on Stage, featured many of the best innovations in physics teaching from the 22 countries which sent delegations (see News). It is probably no surprise, but we need to take note that the most popular stands, talks and lectures were the ones which were most fun. And there is lots of fun to be had doing physics. Whether it is toys, music, poetry, or simply talking about the symmetry in particle physics-the most popular stands, workshops and lectures were those where teachers could enjoy the fun in physics again. Even physics teachers are human! It is so easy to get bogged down in the drudge of everyday teaching and forget the students, let alone ourselves. But if you think back to the good teachers you had at school - weren't they the ones who were enjoying themselves, and maybe not perfectly organized. There has to be a moment at which a good teacher says 'I'm going to do this, because I want to... it's fun physics!' No other justification is needed. Our new look for 2001 So here is the first issue of the new-look Physics Education - and we sincerely hope that you enjoy it. The Editorial Board and the publishing team have been working hard for the past few months to keep the best of the old format, but to make a fresher, more user-friendly publication. As incoming Editor I must acknowledge the excellent work done by Ken Dobson and Jill Membrey, the outgoing team. It is a tough act to follow, but a challenge I am privileged to undertake. As a physics teacher I know how difficult it can be to stay inspired and up-to-date, so as Editor of Physics Education I want to support your professional development as much as possible. Starting with support for student teachers (see Starting Out), through to teachers in charge of equipment and budgets (see Technical Trimmings and Reviews): we want to share good practice. Finally, let's laugh at ourselves-don't miss Signing Off: a humorous look at physics teaching. I've really enjoyed working on this new format, and I hope that you enjoy the read. Please give us lots of feedback and send in your own contributions. I'm very pleased that our first issue has two special features: to me they represent the potential and the purpose of physics education. Sport is an exciting growth area of science in which increasing numbers of students want to understand the basic laws of motion and the application of sophisticated technology; and communicating physics - well that's not just fun, it's fundamental.

Among children who remain at home with their permanent caregivers following a child welfare investigation, few who manifest emotional and behavioral difficulties actually engage in mental health treatment. The Multiple Family Group service delivery model to reduce childhood disruptive behavior disorders (MFG) has shown promise in engaging child welfare-involved families. This qualitative study examines caregiver perceptions of factors that influence retention in MFGs among child welfare-involved families. Methods Twenty-five predominantly Black and Hispanic adult (ages 26–57) female caregivers with child welfare services involvement participated in individual, in-depth interviews about their experience with MFGs. Transcribed interview data were thematically coded guided by grounded theory methodology. Emergent themes were subsequently organized into a conceptual framework. Results Within the overarching influence of child welfare services involvement, specific components of MFGs influencing retention included the quality of interaction among group members, group facilitators’ attentive approach with caregivers, supports designed to overcome logistical barriers (i.e., child care, transportation expenses, meals), and perceptions of MFG content and activities as fun and helpful. Caregiver factors, including their mental health and personal characteristics, as well as children’s behavior, (i.e., observed changes in behavioral difficulties) were also associated with retention. Conclusions High acceptability suggest utility for implementing MFGs within settings serving child welfare involved families, with additional modifications to tailor to setting and client features.

Obesity and metabolic syndrome can be labeled as worldwide outbreak; thus, both have led to serious public health problem. Oral health can be worsened by both, obesity and metabolic syndrome. Tooth loss harms masticatory function, essential status to whom will be submitted to bariatric surgery. Assess masticatory function of obese candidates to bariatric surgery, who belong to distinct socioeconomic class range, in order to recognize hazard factors and the bias of socioeconomic factor in this context. Observational cross-section study, with samples comprised by two groups of patients, with distinct socioeconomic class range, one of them belonging to public health system (SUSG) and the other to private clinic (CPG), candidates to bariatric surgery. Were assessed anthropometric data, comorbidities and medicines usage, blood tests, habits and the number of dental functional units. The groups SUSG and CPG were homogeneous taking into account gender (p=0,890) and age range (p=0,170). The number of dental functional units was higher in the private group (p<0.001). The impaired masticatory function was rather present among public group (p<0.001) and female gender (p<0,001). Regarded as blood tests, fasting glucose was higher in female in SUSG (p<0,001). The following hazard factors have corroborated to have patients rated as impaired masticatory function: belong to public service (OR: 8.420, p=0.003), higher age (OR: 1.186, p<0.001), female gender (OR: 0.153, p=0.029), diabetes mellitus (OR: 2.545, p=0.045) and smokers (OR: 2.951, p=0.043). The general health and masticatory function of female SUSG were worse, highlighting the socioeconomic condition as hazard factor. Obesidade e síndrome metabólica são graves problemas de saúde pública, com características de epidemia mundial. A saúde bucal é agravada por ambas as condições. Perda dentária prejudica função mastigatória, condição essencial para o paciente que será submetido à cirurgia bariátrica. Avaliar a função mastigatória de pacientes obesos candidatos à cirurgia bariátrica pertencentes a dois serviços de saúde com padrões socioeconômicos distintos, afim de identificar fatores de risco e a influência do fator socioeconômico nesta condição. Estudo observacional transversal, com amostra constituída por dois grupos de pacientes obesos, com condições socioeconômicas distintas, um pertencente ao sistema público de saúde (GSUS) e outro à clínica privada (GCP), candidatos à cirurgia bariátrica. Foram analisados dados antropométricos, comorbidades e uso de medicamentos para seu controle, exames laboratoriais, hábitos e o número de unidades funcionais dentárias presentes. Os grupos GSUS e GCP foram homogêneos quanto ao gênero (p=0,890) e faixa etária (p=0,170). A média de unidades funcionais dentárias foi maior no grupo privado (p<0,001). A função mastigatória prejudicada foi mais presente no grupo GSUS e no gênero feminino (p<0,001). Quanto aos exames laboratoriais: glicemia de jejum esteve mais alterada em mulheres do GSUS (p<0,001). Foram fatores de risco independentes para ter função mastigatória prejudicada: ter origem no serviço público de saúde (OR: 8,420 - p=0,003), maior idade (OR: 1,186 - p<0,001), ser do gênero feminino (OR: 0,153 - p=0,029), portador de diabete melito (OR: 2,545 - p=0,045) e tabagista (OR: 2,951 - p=0,043). A saúde geral e função mastigatória de mulheres do GSUS foram piores, ressaltando a condição socioeconômica como fator de risco.

Hahn-Markowitz, Jeri; Berger, Itai; Manor, Iris; Maeir, Adina

2016-09-16

To examine the efficacy of a Cognitive-Functional (Cog-Fun) intervention for children with ADHD. Random allocation of 107 children to study or control groups preceded 10 parent-child weekly Cog-Fun sessions emphasizing executive strategy training in games and daily activities. Controls received treatment after crossover. Study participants were followed up 3 months post-treatment. Outcomes included parent/teacher ratings of executive functions, ADHD symptoms, and parent ratings of quality of life. Eight children withdrew prior to treatment. All children in both groups who began treatment completed it. Mixed effects ANOVA revealed significant Time × Group interaction effects on all parent-reported outcomes. Treatment effects were moderate to large, replicated after crossover in the control group and not moderated by medication. Parent-reported treatment gains in the study group were maintained at follow-up. No significant Time × Group interaction effects were found on teacher outcomes. Cog-Fun occupational therapy (OT) intervention shows positive context-specific effects on parent, but not teacher, ratings. © The Author(s) 2016.

How much control is enough? Influence of unreliable input on user experience.

Brain–computer interfaces (BCI) provide a valuable new input modality within human–computer interaction systems. However, like other body-based inputs such as gesture or gaze based systems, the system recognition of input commands is still far from perfect. This raises important questions, such as what level of control should such an interface be able to provide. What is the relationship between actual and perceived control? And in the case of applications for entertainment in which fun is an important part of user experience, should we even aim for the highest level of control, or is the optimum elsewhere? In this paper, we evaluate whether we can modulate the amount of control and if a game can be fun with less than perfect control. In the experiment users (n = 158) played a simple game in which a hamster has to be guided to the exit of a maze. The amount of control the user has over the hamster is varied. The variation of control through confusion matrices makes it possible to simulate the experience of using a BCI, while using the traditional keyboard for input. After each session the user completed a short questionnaire on user experience and perceived control. Analysis of the data showed that the perceived control of the user could largely be explained by the amount of control in the respective session. As expected, user frustration decreases with increasing control. Moreover, the results indicate that the relation between fun and control is not linear. Although at lower levels of control fun does increase with improved control, the level of fun drops just before perfect control is reached (with an optimum around 96%). This poses new insights for developers of games who want to incorporate some form of BCI or other modality with unreliable input in their game: for creating a fun game, unreliable input can be used to create a challenge for the user.

Genetic Feedback Regulation of Frontal Cortical Neuronal Ensembles Through Activity-Dependent Arc Expression and Dopaminergic Input.

PubMed

Mastwal, Surjeet; Cao, Vania; Wang, Kuan Hong

2016-01-01

Mental functions involve coordinated activities of specific neuronal ensembles that are embedded in complex brain circuits. Aberrant neuronal ensemble dynamics is thought to form the neurobiological basis of mental disorders. A major challenge in mental health research is to identify these cellular ensembles and determine what molecular mechanisms constrain their emergence and consolidation during development and learning. Here, we provide a perspective based on recent studies that use activity-dependent gene Arc/Arg3.1 as a cellular marker to identify neuronal ensembles and a molecular probe to modulate circuit functions. These studies have demonstrated that the transcription of Arc is activated in selective groups of frontal cortical neurons in response to specific behavioral tasks. Arc expression regulates the persistent firing of individual neurons and predicts the consolidation of neuronal ensembles during repeated learning. Therefore, the Arc pathway represents a prototypical example of activity-dependent genetic feedback regulation of neuronal ensembles. The activation of this pathway in the frontal cortex starts during early postnatal development and requires dopaminergic (DA) input. Conversely, genetic disruption of Arc leads to a hypoactive mesofrontal dopamine circuit and its related cognitive deficit. This mutual interaction suggests an auto-regulatory mechanism to amplify the impact of neuromodulators and activity-regulated genes during postnatal development. Such a mechanism may contribute to the association of mutations in dopamine and Arc pathways with neurodevelopmental psychiatric disorders. As the mesofrontal dopamine circuit shows extensive activity-dependent developmental plasticity, activity-guided modulation of DA projections or Arc ensembles during development may help to repair circuit deficits related to neuropsychiatric disorders.

Catecholamine and second messenger influences on prefrontal cortical networks of "representational knowledge": a rational bridge between genetics and the symptoms of mental illness.

PubMed

Arnsten, Amy F T

2007-09-01

Both dopamine (DA) and norepinephrine (NE) have powerful, inverted U influences on prefrontal cortical (PFC) cognitive function. Optimal NE levels engage alpha2A-adrenoceptors and increase "signals" via inhibition of cAMP-HCN (cAMP-hyperpolarization-activated cyclic nucleotide-gated cation channel) signaling near preferred inputs, whereas optimal levels of DA D1 receptor stimulation decrease "noise" by increasing cAMP signaling near nonpreferred inputs. Excessive levels of catecholamine release during stress impair working memory 1) by very high levels of cAMP-HCN signaling diminishing preferred as well as nonpreferred inputs and 2) by high levels of NE engaging alpha1 stimulation of phosphotidyl inositol (PI) signaling that suppresses cell firing. Common mental illnesses are associated with extracellular changes in these pathways: Attention Deficit Hyperactivity Disorder is linked to genetic changes that reduce catecholamine transmission to suboptimal levels and is treated with agents that increase catecholamine transmission, whereas Post-Traumatic Stress Disorder (PTSD) is associated with amplified noradrenergic transmission that impairs PFC but strengthens amygdala function. PTSD is now treated with agents that block alpha1 or beta adrenoceptors. In contrast, the more severe mental illnesses, schizophrenia and bipolar disorder, are associated with genetic changes in molecules regulating intracellular signaling pathways activated by stress. Specifically, DISC1 inhibits cAMP signaling whereas regulator of G-protein signaling 4 inhibits PI signaling. Loss of function in these genes may render patients vulnerable to profound stress-induced PFC dysfunction including symptoms of thought disorder.

Healthy diet and physical activity can improve metabolic control in patients with type 2 diabetes mellitus. However, lifestyle change without external help is difficult: an alteration of mental attitude is necessary to achieve long-term success. A computer-based motivational program ("Da Vinci") has been developed to help patients to change their mental attitudes and beliefs. Patients with type 2 diabetes were supervised by psychological trainers in four sessions at ten study centers. The interactive computer program allowed for identification of motivation restraints and overcoming them. Parameters of carbohydrate metabolism were measured at the beginning and end of the three-months program as well as three and six months after end of program. All participants (n = 61) developed a positive attitude towards the range of their action and by themselves changed their lifestyle. After three months their weight (-4.6 kg; p < 0.0001), body mass index (-1.1 kg/m2; p < 0.0001), waist circumference (-3.5 cm; p < 0.0001), HbA1c (-0.6 %; p < 0.0001), triglycerides (-31.1 mg/dl; p = 0.033), systolic (-4.0 mmHg; p = 0.005) and diastolic blood pressure (-3.0 mmHg; p = 0.006) had been reduced. Short duration of diabetes and high baseline HbA1c values were predictive for successful HbA1c reduction. Three and six months after end of the program participants were able to maintain or even augment achieved improvements. During the motivational program, which is intended to alter mental attitude and beliefs, but not to teach knowledge about diabetes, participants were able to significantly improve their metabolic control. As these improvements were maintained long-term, this points to sustainable lifestyle change. © Georg Thieme Verlag KG Stuttgart · New York.

Espectroscopia de candidatos a remanescentes de aglomerados abertos

NASA Astrophysics Data System (ADS)

Pavani, D. B.; Bica, E.; Ahumada, A. V.; Clariá, J. J.

2003-08-01

A pesquisa sobre remanescentes de aglomerados abertos tem despertado grande interesse. Seguindo esta tendência encontramos estudos teóricos e observacionais. Os primeiros baseiam-se em simulações numéricas buscando determinar fração de binárias e distâncias galatocêntricas, tempo de vida e conteúdo estelar. Estes estão relacionados à função inicial de massa e densidade de estrelas, ou seja, se ricos ou pobremente povoados, compactos ou esparsos. No caso observacional procuram-se identificar os remanescentes considerando-se que trazem estas assinaturas de seus percursores. No presente estudo empregamos espectroscopia para analisar oito concentrações pobremente povoadas, previamente classificadas como aglomerados abertos, sendo sete compactas e uma esparsa. As observações foram obtidas através do telescópio de 2,15 m do CASLEO em San Juan, Argentina, em turnos entre 2001 e 2003. Utilizamos uma câmara CCD contendo um chip Tektronics de 1024X1024 pixeis aliado a um espectrógrafo REOSC. O domínio espectral vai de 3700 a 7000 Å. As reduções foram realizadas no Observatório Astronômico de Córdoba (Argentina) usando pacotes IRAF padrões. Determinamos idades, avermelhamentos e tipos espectrais através de comparações com biblioteca de estrelas e de aglomerados. Em alguns casos nossos espectros estavam dominados por estrelas individuais às quais determinamos seus tipos espectrais. Aos oito objetos adicionamos mais cinco da literatura recente analisados via espectro ou diagrama cor-magnitude. O histograma resultante contém idades típicas entre 0.5 e 3 Ganos. Considerando que predominantemente estes objetos encontram-se na vizinhança solar e, portanto, não cruzaram muitas vezes o plano Galático esperamos que a diferença no tempo necessário para dissolução destes prováveis remanescentes seja em função de diferentes massas iniciais.

Vatsa, Veer N.; Lockard, David P.; Khorrami, Mehdi R.

2011-01-01

Numerical simulations have been performed for a nose landing gear configuration corresponding to the experimental tests conducted in the Basic Aerodynamic Research Tunnel at NASA Langley Research Center. A widely used unstructured grid code, FUN3D, is examined for solving the unsteady flow field associated with this configuration. A series of successively finer unstructured grids has been generated to assess the effect of grid refinement. Solutions have been obtained on purely tetrahedral grids as well as mixed element grids using hybrid RANS/LES turbulence models. The agreement of FUN3D solutions with experimental data on the same size mesh is better on mixed element grids compared to pure tetrahedral grids, and in general improves with grid refinement.

Thirty-one semi-structured interviews with municipal, regional and state managers were carried out, besides a cross-sectional survey with the administration of questionnaires to physicians (74), nurses (127), and a representative sample of users (1,590) of Estratégia Saúde da Família (Family Health Strategy) in three municipal centers of health regions in the state of Bahia. Primary Health Care as first contact of preference faced strong competition from hospital outpatient and emergency services outside the network. Issues related to access to and provision of specialized care were aggravated by dependence on the private sector in the regions, despite progress observed in institutionalizing flows starting out from Primary Health Care. The counter-referral system was deficient and interprofessional communication was scarce, especially concerning services provided by the contracted network. Coordination capacity is affected both by the fragmentation of the regional network and intrinsic problems in Primary Health Care, which poorly supported in its essential attributes. Although the health regions have common problems, Primary Health Care remains a subject confined to municipal boundaries. Analisar o alcance da coordenação do cuidado pela Atenção Primária à Saúde em três regiões de saúde. Trata-se de estudo de caso, com abordagem quantitativa e qualitativa. Foram realizadas 31 entrevistas semiestruturadas com gestores municipais, regionais e estaduais e estudo transversal com aplicação de questionários para médicos (74), enfermeiros (127) e amostra representativa de usuários (1.590) da Estratégia Saúde da Família em três municípios-sede de regiões de saúde do estado da Bahia. A função de porta de entrada preferencial pela Atenção Primária à Saúde deparava-se com forte concorrência de serviços ambulatoriais hospitalares e de pronto-atendimento, desarticulados da rede. Problemas de acesso e oferta de atenção especializada eram agravados pela dependência do setor privado nas regiões, ainda que tenham sido observados avanços na institucionalização de fluxos desde a Atenção Primária à Saúde. A contrarreferência era deficiente e a comunicação interprofissional escassa, principalmente quando o usuário era atendido na rede contratada ou conveniada. A capacidade de coordenação mostra-se afetada tanto pela fragmentação da rede regional, quanto por problemas intrínsecos à Atenção Primária à Saúde, pouco fortalecida em seus atributos essenciais. Apesar de as regiões de saúde apresentarem problemas em comum, a Atenção Primária à Saúde continua sendo um tema circunscrito aos limites municipais.

Impairment of fragile X mental retardation protein-metabotropic glutamate receptor 5 signaling and its downstream cognates ras-related C3 botulinum toxin substrate 1, amyloid beta A4 precursor protein, striatal-enriched protein tyrosine phosphatase, and homer 1, in autism: a postmortem study in cerebellar vermis and superior frontal cortex

Background Candidate genes associated with idiopathic forms of autism overlap with other disorders including fragile X syndrome. Our laboratory has previously shown reduction in fragile X mental retardation protein (FMRP) and increase in metabotropic glutamate receptor 5 (mGluR5) in cerebellar vermis and superior frontal cortex (BA9) of individuals with autism. Methods In the current study we have investigated expression of four targets of FMRP and mGluR5 signaling - homer 1, amyloid beta A4 precursor protein (APP), ras-related C3 botulinum toxin substrate 1 (RAC1), and striatal-enriched protein tyrosine phosphatase (STEP) - in the cerebellar vermis and superior frontal cortex (BA9) via SDS-PAGE and western blotting. Data were analyzed based on stratification with respect to age (children and adolescents vs. adults), anatomic region of the brain (BA9 vs. cerebellar vermis), and impact of medications (children and adolescents on medications (n = 4) vs. total children and adolescents (n = 12); adults on medications (n = 6) vs. total adults (n = 12)). Results There were significant increases in RAC1, APP 120 kDa and APP 80 kDa proteins in BA9 of children with autism vs. healthy controls. None of the same proteins were significantly affected in cerebellar vermis of children with autism. In BA9 of adults with autism there were significant increases in RAC1 and STEP 46 kDa and a significant decrease in homer 1 vs. controls. In the vermis of adult subjects with autism, RAC1 was significantly increased while APP 120, STEP 66 kDa, STEP 27 kDa, and homer 1 were significantly decreased when compared with healthy controls. No changes were observed in vermis of children with autism. There was a significant effect of anticonvulsant use on STEP 46 kDa/β-actin and a potential effect on homer 1/NSE, in BA9 of adults with autism. However, no other significant confound effects were observed in this study. Conclusions Our findings provide further evidence of abnormalities in FMRP and mGluR5 signaling partners in brains of individuals with autism and open the door to potential targeted treatments which could help ameliorate the symptoms of autism.

Um supressor de fundo térmico para a câmara infravermelha CamIV

2003-08-01

O ângulo sólido subtendido pelos pixels na câmara infravermelha do NexGal (CamIV) que operamos no OPD/LNA contém contribuições provenientes do sistema de coleta de fluxo propriamente dito - sendo esta a parte que interessa para as medidas astronômicas - e contribuições da obstrução central, sistema de suporte do espelho secundário e região exterior à pupila de entrada do telescópio. Estas últimas contribuições são devi-das à emissão de corpo negro à temperatura ambiente e aumentam exponencialmente para comprimentos de onda maiores que 2 micra (banda K, no infravermelho próximo). Embora a resultante pode ser quantificada e subtraída dos sinais relevantes, sua variância se adiciona à variância do sinal, e pode ser facilmente a contribuição domi-nante para a incerteza final das medidas, tornando ineficiente o processo de extração de informação e degradando a sensibilidade da câmara. A maneira clássica de resolver esse problema em sistemas ópticos que operam no infravermelho, onde os efeitos da emissão térmica do ambiente são importantes, é restringir o ângulo sólido subtendido pelos pixels individuais exclusivamente aos raios provenientes do sistema óptico. Para tanto, projeta-se uma imagem real, bastante reduzida, da pupila de entrada do sistema óptico num anteparo que transmita para o sistema de imageamento só o que interessa, bloqueando as contribuições das bordas externas à pupila de entrada, obstrução central do telescópio e sistema de suporte. Como a projeção é realizada em ambiente criogênico, a contribuição térmica espúria é efetivamente eliminada. Nós optamos por um sistema do tipo Offner para implementar na prática esta função. Trata-se de um sistema baseado em espelhos esféricos, bastante compacto e ajustado por construção. A opção por espelhos do mesmo material que o sistema de suporte (Alumínio) minimiza a dilatação diferencial, crítica nesse tipo de aplicação. Apresentamos as soluções detalhadas do projeto óptico-mecânico, bem como uma análise de flexões e desempenho em termos de qualidade de imagem.

Specific protein interactions are responsible for most biological functions. Distinguishing Functionally Linked Interfaces of Proteins (FLIPs), from Functionally uncorrelated Contacts (FunCs), is therefore important to characterizing these interactions. To achieve this goal, we have created a database of protein structures called FLIPdb, containing proteins belonging to various functional sub-categories. Here, we use geometric features coupled with Kortemme and Baker's computational alanine scanning method to calculate the energetic sensitivity of each amino acid at the interface to substitution, identify hotspots, and identify other factors that may contribute towards an interface being FLIP or FunC. Using Principal Component Analysis and K-means clustering on a training set of 160 interfaces, we could distinguish FLIPs from FunCs with an accuracy of 76%. When these methods were applied to two test sets of 18 and 170 interfaces, we achieved similar accuracies of 78% and 80%. We have identified that FLIP interfaces have a stronger central organizing tendency than FunCs, due, we suggest, to greater specificity. We also observe that certain functional sub-categories, such as enzymes, antibody-heavy-light, antibody-antigen, and enzyme-inhibitors form distinct sub-clusters. The antibody-antigen and enzyme-inhibitors interfaces have patterns of physical characteristics similar to those of FunCs, which is in agreement with the fact that the selection pressures of these interfaces is differently evolutionarily driven. As such, our ECR model also successfully describes the impact of evolution and natural selection on protein-protein interfaces. Finally, we indicate how our ECR method may be of use in reducing the false positive rate of docking calculations.

2014-01-01

The fluorescent vital dye FUN®-1 (2-chloro-4-[2,3-dihydro-3-methyl-{benzo-1,3-thiazol-2-yl}-methylidene]-1-phenylquinolinium iodide) was evaluated as a tool to assess Phytophthora capsici sporangia and zoospore metabolic activity and viability. Under aerobic conditions, mycelia, sporangia and zoospores cultured on agar medium and stained with FUN-1 exhibited red fluorescent cylindrical intravacuolar structures (CIVS) that were clearly visible at 100× magnification. Encysted zoospores did not exhibit CIVS after exposure to FUN-1 dye. Over 7 d there was a significant reduction in the percent of sporangia containing CIVS, which corresponded with a significant increase in zoospore formation and release. The decline in the percentage of metabolically active sporangia and increase in the number of zoospores fit both a linear and log regression model. The FUN-1 dye was suitable for distinguishing between live and dead sporangia and effective in monitoring the change in metabolic activity of sporangia over time. It will be useful in determining parameters, including P. capsici culture age, that maximize production of zoospores in vitro.

Grid-Adapted FUN3D Computations for the Second High Lift Prediction Workshop

2014-01-01

Contributions of the unstructured Reynolds-averaged Navier-Stokes code FUN3D to the 2nd AIAA CFD High Lift Prediction Workshop are described, and detailed comparisons are made with experimental data. Using workshop-supplied grids, results for the clean wing configuration are compared with results from the structured code CFL3D Using the same turbulence model, both codes compare reasonably well in terms of total forces and moments, and the maximum lift is similarly over-predicted for both codes compared to experiment. By including more representative geometry features such as slat and flap brackets and slat pressure tube bundles, FUN3D captures the general effects of the Reynolds number variation, but under-predicts maximum lift on workshop-supplied grids in comparison with the experimental data, due to excessive separation. However, when output-based, off-body grid adaptation in FUN3D is employed, results improve considerably. In particular, when the geometry includes both brackets and the pressure tube bundles, grid adaptation results in a more accurate prediction of lift near stall in comparison with the wind-tunnel data. Furthermore, a rotation-corrected turbulence model shows improved pressure predictions on the outboard span when using adapted grids.

To describe forms of external and indirect violence that affect the mental health of workers of the Programa Saúde da Família (Family Health Program), as well as the strategies developed by these workers to enable their work and to be psychologically protected. Qualitative study on the Programa Saúde da Família work process, performed in the cities of São Paulo, Ribeirão Preto and Embu (Southeastern Brazil) in 2005. Theoretical approach of psychodynamics of work, which proposes the formation of reflection groups with workers, was employed. Subjective aspects of work, situations of psychological suffering and strategies used by workers to deal with suffering and continue to work were sought to be identified. The Program's work organization exposed workers to the following: situations of violence, invisible at times; feeling of impotence in the face of precarious situations; lack of acknowledgement of efforts made; lack of borders between professional and personal aspects; intense experiences of social and domestic violence; fear of risk of exposure; feeling of moral and physical integrity being threatened; and fear of reprisal. Situations of psychological suffering resulting from violence in the workplace were observed. These became more intense in the Programa Saúde da Família due to regular contact with situations of violence that cause fear and a feeling of vulnerability. Psychological repercussions caused by violence in the workplace, not always expressed in the form of psychological disorders, were observed in situations of intense suffering. Workers develop strategies to minimize suffering, protect themselves psychologically and continue to work; and seek to create solidarity and protection networks with the population, aiming to reduce vulnerability. With the experience gained, they learn to detect high-risk situations, avoiding those they believe to be threatening.

KELT-21b is an exoplanet classified as a hot Jupiter transiting the star HD 332124. The host star has the highest projected rotation velocity of any known star to host a transiting hot Jupiter. This target was found by the KELT (Kilo-degree Extremely Little Telescope) program. KELT-FUN ( Follow-Up Network) is tasked with doing follow up observations for KELT exoplanet candidates. KELT-21b was one of those targets that drew interest due to its size and orbit around a hot star. As a part of the KELT-FUN team photometric observations were taken by the Red Buttes Observatory at the University of Wyoming which contributed to the discovery of KELT-21b. Our experience gained by KELT-FUN will enable us to follow up on targets identified by TESS.

Evolução temporal de discos circunstelares em estrelas Be

A pesquisa do mecanismo que leva uma estrela do tipo Be a perder massa e formar um envelope circunstelar, nomeado como fenômeno Be, é uma questão em aberto, intrigante, e que adquire contornos interessantes em face às informações espectroscópicas de alta resolução. Nesta última década, consolida-se a idéia de que a forma destes envelopes é de tipo discóide, obedecendo a uma lei Kepleriana de velocidades, e mais ainda, recentemente há evidências de que a distribuição de matéria nestes discos pode assumir um caráter de anel. Medidas de algumas dimensões de discos circunstelares puderam ser obtidas pela análise de espectros de alta resolução e alta relação sinal-ruído para as estrelas Be: alpha Eri (HD 10144, B3Vpe), omicron And (HD 217675, B6IIIpe), e eta Cen (HD el972, B1.5Vne), no período dos anos de 1991 a 2001. Alguns modelos clássicos de envelope predizem uma distribuição de massa que decresce suavemente a partir da superfície estelar. Entretanto, considerando que a separação de picos de emissão em perfis de linhas do HeI e H-alpha, alargados por efeitos cinemáticos, é função do raio estelar e da velocidade rotacional projetada (vsini); nossos resultados sugerem a presença de um anel de matéria circunstelar, que aparece logo após a ejeção do material fotosférico, imediatamente acima da superfície estelar, e que se expande para raios maiores ao longo do tempo, eventualmente desconectando-se da superfície por uma região de densidade de matéria mínima. Tais interpretações revivem a idéia de que anéis de matéria circunstelar podem ser os responsáveis por algumas variabilidades em perfis de linhas de emissão, como as variações V/R.

2017-04-01

The practice of exercise in short bouts repeated throughout the day may be an alternative strategy to lift people out of physical inactivity. to evaluate if accumulated exercise, as occurs in continuous exercise training, improve endothelial function in rat aorta. Wistar male rats were divided into three groups: continuous exercise (CEx, 1 hour on the treadmill) or accumulated exercise (AEx, 4 bouts of 15 minutes / day) for 5 days/week for 8 weeks, or sedentary (SED). During the training period, body weight gain and increase in exercise performance were recorded. On sacrifice day, aorta was dissected into rings (3-5 mm) and mounted on the organ bath. Fitness was significantly greater in CEx and AEx rats as compared with SED animals. In addition, compared with the SED group, CEx animals had a lower body mass gain, and the aorta obtained from these animals had reduced contractile response to norepinephrine and greater acetylcholine-induced relaxation. These results were not observed in ACEx animals. Both CEx and AEx improved fitness, but only CEx led to reduced body weight gain and improved endothelial function. A prática de exercícios em sessões curtas que se repetem ao longo do dia pode ser uma alternativa para tirar as pessoas da inatividade física. Verificar se o exercício acumulado, tal como ocorre com o treinamento com exercício contínuo, melhora a função endotelial na aorta de ratos. Ratos Wistar machos foram divididos em 3 grupos: treinamento com exercício contínuo (ExC; 1 hora em esteira) ou com exercício acumulado (ExA; 4 sessões de 15 minutos ao longo do dia) por 5 dias/semana, durante 8 semanas, ou grupo sedentário (SED). Durante o treinamento, foram registrados o ganho de peso corporal e desempenho na esteira. No dia do sacrifício, anéis (3-5 mm) da aorta foram obtidos e montados em banho de órgãos. Animais ExC e ExA mostraram aptidão física significativamente maior em comparação com os SED. Paralelamente, em comparação com SED, animais ExC tiveram menor ganho de massa corporal, e aortas retiradas desses animais mostraram respostas contrácteis à noradrenalina reduzidas e maior relaxamento induzido pela acetilcolina. Esses resultados não foram observados no grupo ExA. Tanto o ExC quanto o ExA melhoraram a aptidão física, mas somente o ExC foi capaz de reduzir o ganho de peso corporal dos animais e melhorar a função endotelial.

To analyze the Miniquestionário de Qualidade de Vida em Hipertensão Arterial (MINICHAL - Mini-questionnaire of Quality of Life in Hypertension) using the Item Response Theory. This is an analytical study conducted with 712 persons with hypertension treated in thirteen primary health care units of Fortaleza, State of Ceará, Brazil, in 2015. The steps of the analysis by the Item Response Theory were: evaluation of dimensionality, estimation of parameters of items, and construction of scale. The study of dimensionality was carried out on the polychoric correlation matrix and confirmatory factor analysis. To estimate the item parameters, we used the Gradual Response Model of Samejima. The analyses were conducted using the free software R with the aid of psych and mirt. The analysis has allowed the visualization of item parameters and their individual contributions in the measurement of the latent trait, generating more information and allowing the construction of a scale with an interpretative model that demonstrates the evolution of the worsening of the quality of life in five levels. Regarding the item parameters, the items related to the somatic state have had a good performance, as they have presented better power to discriminate individuals with worse quality of life. The items related to mental state have been those which contributed with less psychometric data in the MINICHAL. We conclude that the instrument is suitable for the identification of the worsening of the quality of life in hypertension. The analysis of the MINICHAL using the Item Response Theory has allowed us to identify new sides of this instrument that have not yet been addressed in previous studies. Analisar o Miniquestionário de Qualidade de Vida em Hipertensão Arterial (MINICHAL) por meio da Teoria da Resposta ao Item. Estudo analítico realizado com 712 pessoas com hipertensão arterial atendidas em 13 unidades de atenção primária em saúde de Fortaleza, CE, em 2015. As etapas da análise pela Teoria da Resposta ao Item foram: avaliação da dimensionalidade, estimação dos parâmetros dos itens e construção da escala. O estudo da dimensionalidade foi realizado sobre a matriz de correlação policórica e análise fatorial confirmatória. Para a estimação dos parâmetros dos itens, foi utilizado o Modelo de Resposta Gradual de Samejima. As análises foram conduzidas no software livre R com o auxílio dos pacotes psych e mirt. A análise permitiu a visualização dos parâmetros dos itens e suas contribuições individuais na mensuração do traço latente, gerando mais informação, permitindo a construção de uma escala com um modelo interpretativo que demonstra a evolução da piora da qualidade de vida em cinco níveis. Quanto aos parâmetros dos itens, houve bom desempenho daqueles referentes ao estado somático, pois apresentaram melhor poder de discriminar os indivíduos com pior qualidade de vida. Os itens relacionados ao estado mental foram os que contribuíram com menor quantidade de informação psicométrica no MINICHAL. Conclui-se que o instrumento é indicado para a identificação da deterioração da qualidade de vida em hipertensão arterial. A análise do MINICHAL pela Teoria da Resposta ao Item permitiu identificar novas facetas desse instrumento ainda não abordadas em estudos anteriores.

We describe a method based on a latent Dirichlet allocation model for predicting functional effects of noncoding genetic variants in a cell-type- and/or tissue-specific way (FUN-LDA). Using this unsupervised approach, we predict tissue-specific functional effects for every position in the human genome in 127 different tissues and cell types. We demonstrate the usefulness of our predictions by using several validation experiments. Using eQTL data from several sources, including the GTEx project, Geuvadis project, and TwinsUK cohort, we show that eQTLs in specific tissues tend to be most enriched among the predicted functional variants in relevant tissues in Roadmap. We further show how these integrated functional scores can be used for (1) deriving the most likely cell or tissue type causally implicated for a complex trait by using summary statistics from genome-wide association studies and (2) estimating a tissue-based correlation matrix of various complex traits. We found large enrichment of heritability in functional components of relevant tissues for various complex traits, and FUN-LDA yielded higher enrichment estimates than existing methods. Finally, using experimentally validated functional variants from the literature and variants possibly implicated in disease by previous studies, we rigorously compare FUN-LDA with state-of-the-art functional annotation methods and show that FUN-LDA has better prediction accuracy and higher resolution than these methods. In particular, our results suggest that tissue- and cell-type-specific functional prediction methods tend to have substantially better prediction accuracy than organism-level prediction methods. Scores for each position in the human genome and for each ENCODE and Roadmap tissue are available online (see Web Resources). Copyright © 2018 American Society of Human Genetics.

RNA interference (RNAi) is involved in genome defense as well as diverse cellular, developmental, and physiological processes. Key components of RNAi are Argonaute, Dicer, and RNA-dependent RNA polymerase (RdRP), which have been functionally characterized mainly in model organisms. The key components are believed to exist throughout eukaryotes; however, there is no systematic platform for archiving and dissecting these important gene families. In addition, few fungi have been studied to date, limiting our understanding of RNAi in fungi. Here we present funRNA http://funrna.riceblast.snu.ac.kr/, a fungal kingdom-wide comparative genomics platform for putative genes encoding Argonaute, Dicer, and RdRP. To identify and archive genes encoding the abovementioned key components, protein domain profiles were determined from reference sequences obtained from UniProtKB/SwissProt. The domain profiles were searched using fungal, metazoan, and plant genomes, as well as bacterial and archaeal genomes. 1,163, 442, and 678 genes encoding Argonaute, Dicer, and RdRP, respectively, were predicted. Based on the identification results, active site variation of Argonaute, diversification of Dicer, and sequence analysis of RdRP were discussed in a fungus-oriented manner. funRNA provides results from diverse bioinformatics programs and job submission forms for BLAST, BLASTMatrix, and ClustalW. Furthermore, sequence collections created in funRNA are synced with several gene family analysis portals and databases, offering further analysis opportunities. funRNA provides identification results from a broad taxonomic range and diverse analysis functions, and could be used in diverse comparative and evolutionary studies. It could serve as a versatile genomics workbench for key components of RNAi.

Detailed petrologic, geochemical and isotopic analyses of a new FUN CAI from the Allende CV3 meteorite (designated CMS-1) indicate that it formed by extensive melting and evaporation of primitive precursor material(s). The precursor material(s) condensed in a 16O-rich region (δ17O and δ18O ∼ -49‰) of the inner solar nebula dominated by gas of solar composition at total pressures of ∼10-3-10-6 bar. Subsequent melting of the precursor material(s) was accompanied by evaporative loss of magnesium, silicon and oxygen resulting in large mass-dependent isotope fractionations in these elements (δ25Mg = 30.71-39.26‰, δ29Si = 14.98-16.65‰, and δ18O = -41.57 to -15.50‰). This evaporative loss resulted in a bulk composition similar to that of compact Type A and Type B CAIs, but very distinct from the composition of the original precursor condensate(s). Kinetic fractionation factors and the measured mass-dependent fractionation of silicon and magnesium in CMS-1 suggest that ∼80% of the silicon and ∼85% of the magnesium were lost from its precursor material(s) through evaporative processes. These results suggest that the precursor material(s) of normal and FUN CAIs condensed in similar environments, but subsequently evolved under vastly different conditions such as total gas pressure. The chemical and isotopic differences between normal and FUN CAIs could be explained by sorting of early solar system materials into distinct physical and chemical regimes, in conjunction with discrete heating events, within the protoplanetary disk.

Mitotic and cytokinetic processes harness cell machinery to drive chromosomal segregation and the physical separation of dividing cells. Here, we investigate the functional requirements for exocyst complex function during cell division in vivo, and demonstrate a common mechanism that directs anaphase cell elongation and cleavage furrow progression during cell division. We show that onion rings (onr) and funnel cakes (fun) encode the Drosophila homologs of the Exo84 and Sec8 exocyst subunits, respectively. In onr and fun mutant cells, contractile ring proteins are recruited to the equatorial region of dividing spermatocytes. However, cytokinesis is disrupted early in furrow ingression, leading to cytokinesis failure. We use high temporal and spatial resolution confocal imaging with automated computational analysis to quantitatively compare wild-type versus onr and fun mutant cells. These results demonstrate that anaphase cell elongation is grossly disrupted in cells that are compromised in exocyst complex function. Additionally, we observe that the increase in cell surface area in wild type peaks a few minutes into cytokinesis, and that onr and fun mutant cells have a greatly reduced rate of surface area growth specifically during cell division. Analysis by transmission electron microscopy reveals a massive build-up of cytoplasmic astral membrane and loss of normal Golgi architecture in onr and fun spermatocytes, suggesting that exocyst complex is required for proper vesicular trafficking through these compartments. Moreover, recruitment of the small GTPase Rab11 and the PITP Giotto to the cleavage site depends on wild-type function of the exocyst subunits Exo84 and Sec8. Finally, we show that the exocyst subunit Sec5 coimmunoprecipitates with Rab11. Our results are consistent with the exocyst complex mediating an essential, coordinated increase in cell surface area that potentiates anaphase cell elongation and cleavage furrow ingression.

FUN3D Navier-Stokes solutions were computed for the 4th AIAA Drag Prediction Workshop grid convergence study, downwash study, and Reynolds number study on a set of node-based mixed-element grids. All of the baseline tetrahedral grids were generated with the VGRID (developmental) advancing-layer and advancing-front grid generation software package following the gridding guidelines developed for the workshop. With maximum grid sizes exceeding 100 million nodes, the grid convergence study was particularly challenging for the node-based unstructured grid generators and flow solvers. At the time of the workshop, the super-fine grid with 105 million nodes and 600 million elements was the largest grid known to have been generated using VGRID. FUN3D Version 11.0 has a completely new pre- and post-processing paradigm that has been incorporated directly into the solver and functions entirely in a parallel, distributed memory environment. This feature allowed for practical pre-processing and solution times on the largest unstructured-grid size requested for the workshop. For the constant-lift grid convergence case, the convergence of total drag is approximately second-order on the finest three grids. The variation in total drag between the finest two grids is only 2 counts. At the finest grid levels, only small variations in wing and tail pressure distributions are seen with grid refinement. Similarly, a small wing side-of-body separation also shows little variation at the finest grid levels. Overall, the FUN3D results compare well with the structured-grid code CFL3D. The FUN3D downwash study and Reynolds number study results compare well with the range of results shown in the workshop presentations.

Several homology-dependent pathways can repair potentially lethal DNA double-strand breaks (DSBs). The first step common to all homologous recombination reactions is the 5′-3′ degradation of DSB ends that yields 3′ single-stranded DNA (ssDNA) required for loading of checkpoint and recombination proteins. The Mre11-Rad50-Xrs2/NBS1 complex and Sae2/CtIP initiate end resection while long-range resection depends on the exonuclease Exo1 or the helicase-topoisomerase complex Sgs1-Top3-Rmi1 with the endonuclease Dna21-6. DSBs occur in the context of chromatin, but how the resection machinery navigates through nucleosomal DNA is a process that is not well understood7. Here, we show that the yeast S. cerevisiae Fun30 protein and its human counterpart SMARCAD18, two poorly characterized ATP-dependent chromatin remodelers of the Snf2 ATPase family, are novel factors that are directly involved in the DSB response. Fun30 physically associates with DSB ends and directly promotes both Exo1- and Sgs1-dependent end resection through a mechanism involving its ATPase activity. The function of Fun30 in resection facilitates repair of camptothecin (CPT)-induced DNA lesions, and it becomes dispensable when Exo1 is ectopically overexpressed. Interestingly, SMARCAD1 is also recruited to DSBs and the kinetics of recruitment is similar to that of Exo1. Loss of SMARCAD1 impairs end resection, recombinational DNA repair and renders cells hypersensitive to DNA damage resulting from CPT or PARP inhibitor treatments. These findings unveil an evolutionarily conserved role for the Fun30 and SMARCAD1 chromatin remodelers in controlling end resection, homologous recombination and genome stability in the context of chromatin.

The effect of playing a science center-based mobile game: Affective outcomes and gender differences

NASA Astrophysics Data System (ADS)

Atwood-Blaine, Dana

Situated in a hands-on science center, The Great STEM Caper was a collaborative mobile game built on the ARIS platform that was designed to engage 5th-9th grade players in NGSS science and engineering practices while they interacted with various exhibits. Same gender partners sharing one iPad would search for QR codes placed at specific exhibits; scanning a code within the game would launch a challenge for that exhibit. The primary hypothesis was that in- game victories would be equivalent to "mastery experiences" as described by Bandura (1997) and would result in increased science self-efficacy. Gender differences in gameplay behaviors and perceptions were also studied. The study included two groups, one that played the game during their visit and one that explored the science center in the traditional way. The Motivation to Learn Science Questionnaire was administered to participants in both groups both before and after their visit to the science center. Participants wore head-mounted GoPro cameras to record their interactions within the physical and social environment. No differences in affective outcomes were found between the game and comparison groups or between boys and girls in the game group. The MLSQ was unable to measure any significant change in science self-efficacy, interest and enjoyment of science, or overall motivation to learn science in either group. However, girls outperformed boys on every measure of game achievement. Lazzaro's (2004) four types of fun were found to be a good fit for describing the gender differences in game perceptions and behaviors. Girls tended to enjoy hard fun and collaborative people fun while boys enjoyed easy fun and competitive people fun. While boys associated game achievement with enjoyment and victory, girls perceived their game achievement as difficult, rather than enjoyable or victorious.

Several impulse control disorders such as ADHD, mania, personality disorders or substance abuse share common behavioural traits, like impulsiveness, risk-taking or inflexible behaviour. These disorders are treated with drugs targeting dopamine (DA) and/or serotonin (5-HT). However, the patient's monoamine imbalance that these neurotransmitters compensate is unclear. This study aims to investigate the patterns of DA and 5-HT metabolisms at rest within selected brain regions related to inter-individual variability in six main components of impulsivity/compulsivity (anticipatory hyperactivity, premature responses, delay discounting, risk-taking, perseveration, flexibility). Rats with adaptive and highly inadaptive behaviours were identified in each task and a sensitive biochemical approach allowed mapping of post-mortem endogenous monoamine tissue content in 20 brain areas. Distinct patterns of 5-HT and DA metabolisms were revealed according to the behavioural traits. Except for hyperactive responses, lower control of actions was mainly associated with a lower DA or 5-HT metabolism in prefrontal and/or subcortical areas (i.e. in orbitofrontal cortex (DA), amygdala and anterior cingulate cortex (5-HT) for inflexible and risk-prone rats). Our results reveal the complex nature of behavioural traits related to impulse control disorders through their associated monoaminergic networks at rest, paving the way for understanding the link between mental disorders and drug therapeutic actions.This article is part of the theme issue 'Diverse perspectives on diversity: multi-disciplinary approaches to taxonomies of individual differences'. © 2018 The Author(s).

Predict the number of hospitalizations for asthma and pneumonia associated with exposure to air pollutants in the city of São José dos Campos, São Paulo State. This is a computational model using fuzzy logic based on Mamdani's inference method. For the fuzzification of the input variables of particulate matter, ozone, sulfur dioxide and apparent temperature, we considered two relevancy functions for each variable with the linguistic approach: good and bad. For the output variable number of hospitalizations for asthma and pneumonia, we considered five relevancy functions: very low, low, medium, high and very high. DATASUS was our source for the number of hospitalizations in the year 2007 and the result provided by the model was correlated with the actual data of hospitalization with lag from zero to two days. The accuracy of the model was estimated by the ROC curve for each pollutant and in those lags. In the year of 2007, 1,710 hospitalizations by pneumonia and asthma were recorded in São José dos Campos, State of São Paulo, with a daily average of 4.9 hospitalizations (SD = 2.9). The model output data showed positive and significant correlation (r = 0.38) with the actual data; the accuracies evaluated for the model were higher for sulfur dioxide in lag 0 and 2 and for particulate matter in lag 1. Fuzzy modeling proved accurate for the pollutant exposure effects and hospitalization for pneumonia and asthma approach. Prever o número de internações por asma e pneumonia associadas à exposição a poluentes do ar no município em São José dos Campos, estado de São Paulo. Trata-se de um modelo computacional que utiliza a lógica fuzzy baseado na técnica de inferência de Mamdani. Para a fuzzificação das variáveis de entrada material particulado, ozônio, dióxido de enxofre e temperatura aparente foram consideradas duas funções de pertinência para cada variável com abordagem linguísticas: bom e ruim. Para a variável de saída número internações por asma e pneumonia, foram consideradas cinco funções de pertinências: muito baixo, baixo, médio, alto e muito alto. O número de internações no ano de 2007 foi obtido do Datasus e o resultado fornecido pelo modelo foi correlacionado com os dados reais de internação com defasagem (lag) de zero a dois dias. A acurácia do modelo foi estimada pela curva ROC para cada poluente e nestas defasagens. No ano de 2007 foram registradas 1.710 internações por pneumonia e asma em São José dos Campos, SP, com média diária de 4,9 internações (dp = 2,9). Os dados de saída do modelo mostraram correlação positiva e significativa (r = 0,38) com os dados reais; as acurácias avaliadas para o modelo foram maiores para o dióxido de enxofre nos lag 0 e 2 e para o material particulado no lag 1. Modelagem fuzzy se mostrou acurada para a abordagem de efeitos da exposição aos poluentes e internação por pneumonia e asma.

Gray's Reinforcement Sensitivity Theory (RST) predicts that the Behavioral Inhibition System (BIS) may relate to coping-motivated problem gambling, given its central role in anxiety. Studies examining the BIS-problem gambling association, however, are mixed. The revised RST posits that the Behavioral Approach System (BAS) may moderate the effect of the BIS on coping-motivated problem gambling. A concurrently strong BAS may highlight the negatively reinforcing effects of gambling, which may strengthen coping motives and increase gambling-related harms. We examined these interactive effects to clarify the moderators and mediators of the negative reinforcement pathway to problem gambling. Data came from a larger investigation of problem gambling among individuals with mood disorders. All participants (N = 275) met criteria for a lifetime depressive or bipolar disorder. During a two-day assessment, participants completed a diagnostic assessment and self-reports. Mediated moderation path analysis showed positive indirect effects from the BIS to problem gambling via coping motives at high, but not at low, levels of BAS-Reward Responsiveness and BAS-Fun Seeking. Enhancement motives were also found to mediate the associations of BAS-Fun Seeking and BAS-Drive with problem gambling. Reward Responsiveness and Fun Seeking facets of the BAS may strengthen coping gambling motives within the mood disorders.

Chromatin Immunoprecipitation followed by sequencing (ChIP-seq) generates local accumulations of sequencing reads on the genome ("peaks"), which correspond to specific protein-DNA interactions or chromatin modifications. Peaks are detected by considering their total area above a background signal, usually neglecting their shapes, which instead may convey additional biological information. We present FunChIP, an R/Bioconductor package for clustering peaks according to a functional representation of their shapes: after approximating their profiles with cubic B-splines, FunChIP minimizes their functional distance and classifies the peaks applying a k-mean alignment and clustering algorithm. The whole pipeline is user-friendly and provides visualization functions for a quick inspection of the results. An application to the transcription factor Myc in 3T9 murine fibroblasts shows that clusters of peaks with different shapes are associated with different genomic locations and different transcriptional regulatory activity. The package is implemented in R and is available under Artistic Licence 2.0 from the Bioconductor website (http://bioconductor.org/packages/FunChIP). marco.morelli@iit.it.

2011-04-01

Previous research found that "fun on line" is the most dominant content in seniors' online communities. The present study aimed to further explore the fun culture in these communities and to discover its unique qualities. The study applied an online ethnography (netnography) approach, utilizing a full year's data from 6 leading seniors' online communities. The final database included about 50,000 posts. The majority of posts were part of online social games, including cognitive, associative, and creative games. The main subjects in all contents were sex, gender differences, aging, grandparenting, politics, faith, and alcohol. Main participatory behaviors were selective timing, using expressive style, and personalization of the online character. Although most participants were "lurkers," the active participants nurtured community norms and relationships, as reflected in the written dialogues. In a reality of limited alternatives for digital games that meet older adults' needs and interests, seniors found an independent system to satisfy their need for play. Seniors' online communities provided a unique form of casual leisure, whose nature varied among different groups of participants. The fun culture seemed to offer participants many desired benefits, including meaningful play, liminality and communitas, opportunity to practice and demonstrate their abilities, and means for coping with aging. Therefore, it may have positive impact on seniors' well-being and successful aging.

The Danish study of Functional Disorders (DanFunD) cohort was initiated to outline the epidemiology of functional somatic syndromes (FSS) and is the first larger coordinated epidemiological study focusing exclusively on FSS. FSS are prevalent in all medical settings and can be defined as syndromes that, after appropriate medical assessment, cannot be explained in terms of a conventional medical or surgical disease. FSS are frequent and the clinical importance varies from vague symptoms to extreme disability. No well-described medical explanations exist for FSS, and how to delimit FSS remains a controversial topic. The specific aims with the cohort were to test delimitations of FSS, estimate prevalence and incidence rates, identify risk factors, delimitate the pathogenic pathways, and explore the consequences of FSS. The study population comprises a random sample of 9,656 men and women aged 18–76 years from the general population examined from 2011 to 2015. The survey comprises screening questionnaires for five types of FSS, ie, fibromyalgia, whiplash-associated disorder, multiple chemical sensitivity, irritable bowel syndrome, and chronic fatigue syndrome, and for the unifying diagnostic category of bodily distress syndrome. Additional data included a telephone-based diagnostic interview assessment for FSS, questionnaires on physical and mental health, personality traits, lifestyle, use of health care services and social factors, and a physical examination with measures of cardiorespiratory and morphological fitness, metabolic fitness, neck mobility, heart rate variability, and pain sensitivity. A biobank including serum, plasma, urine, DNA, and microbiome has been established, and central registry data from both responders and nonresponders are similarly available on morbidity, mortality, reimbursement of medicine, heath care use, and social factors. A complete 5-year follow-up is scheduled to take place from year 2017 to 2020, and further reexaminations will be planned. Several projects using the DanFunD data are ongoing, and findings will be published in the coming years. PMID:28275316

Original mechanisms of antipsychotic action by the indole alkaloid alstonine (Picralima nitida).

Alstonine is the major component of plant based remedies that traditional psychiatrists use in Nigeria. Alstonine is an indole alkaloid that has an antipsychotic experimental profile comparable with that of clozapine and is compatible with the alleged effects in mental patients. Representing a desirable innovation in the pharmacodynamics of antipsychotic medications, the evidence indicates that alstonine does not bind to D2 dopamine receptors (D2R) and differentially regulates dopamine in the cortical and limbic areas. The purpose of this study was to further investigate the effects of alstonine on D2R binding in specific brain regions using quantitative autoradiography (QAR) and its effects on dopamine (DA) uptake in mouse striatal synaptosomes. The effects of alstonine on D2R binding were determined in the nucleus accumbens and caudate-putamen using QAR in mice treated with alstonine doses that have antipsychotic effects. The effects of alstonine [3H]DA uptake were assessed in synaptosomes prepared from striatal tissue obtained from mice treated acutely or for 7 days with alstonine. Alstonine did not change the D2R binding densities in the studied regions. DA uptake was increased after acute (but not after 7 days) treatment with alstonine. Consistent with the alstonine behavioral profile, these results indicate that alstonine indirectly modulates DA receptors, specifically by modulating DA uptake. This unique mechanism for DA transmission modulation contributes to the antipsychotic-like effects of alstonine and is compatible with its behavioral profile in mice and alleged effects in patients. These results may represent an innovation in the antipsychotic development field. Copyright © 2014 Elsevier GmbH. All rights reserved.

Calcium-binding protein spermatid-specific 1 (CABS1) is expressed in the human submandibular gland and has an anti-inflammatory motif similar to that in submandibular rat 1 in rats. Here, we investigate CABS1 in human saliva and its association with psychological and physiological distress and inflammation in humans. Volunteers participated across three studies: 1) weekly baseline measures; 2) a psychosocial speech and mental arithmetic stressor under evaluative threat; and 3) during academic exam stress. Salivary samples were analyzed for CABS1 and cortisol. Additional measures included questionnaires of perceived stress and negative affect; exhaled nitric oxide; respiration and cardiac activity; lung function; and salivary and nasal inflammatory markers. We identified a CABS1 immunoreactive band at 27 kDa in all participants and additional molecular mass forms in some participants. One week temporal stability of the 27-kDa band was satisfactory (test–retest reliability estimate = 0.62–0.86). Acute stress increased intensity of 18, 27, and 55 kDa bands; 27-kDa increases were associated with more negative affect and lower heart rate, sympathetic activity, respiration rate, and minute ventilation. In both acute and academic stress, changes in 27 kDa were positively associated with salivary cortisol. The 27-kDa band was also positively associated with VEGF and salivary leukotriene B4 levels. Participants with low molecular weight CABS1 bands showed reduced habitual stress and negative affect in response to acute stress. CABS1 is readily detected in human saliva and is associated with psychological and physiological indicators of stress. The role of CABS1 in inflammatory processes, stress, and stress resilience requires careful study. PMID:28381457

Hahn-Markowitz, Jeri; Berger, Itai; Manor, Iris; Maeir, Adina

We examined the effect of the Cognitive-Functional (Cog-Fun) occupational therapy intervention on executive functions and participation among children with attention deficit hyperactivity disorder (ADHD). We used a randomized, controlled study with a crossover design. One hundred and seven children age 7-10 yr diagnosed with ADHD were allocated to treatment or wait-list control group. The control group received treatment after a 3-mo wait. Outcome measures included the Behavior Rating Inventory of Executive Function (BRIEF) and the Canadian Occupational Performance Measure (COPM). Significant improvements were found on both the BRIEF and COPM after intervention with large treatment effects. Before crossover, significant Time × Group interactions were found on the BRIEF. This study supports the effectiveness of the Cog-Fun intervention in improving executive functions and participation among children with ADHD.

A Nonlinear Modal Aeroelastic Solver for FUN3D

NASA Technical Reports Server (NTRS)

Goldman, Benjamin D.; Bartels, Robert E.; Biedron, Robert T.; Scott, Robert C.

2016-01-01

A nonlinear structural solver has been implemented internally within the NASA FUN3D computational fluid dynamics code, allowing for some new aeroelastic capabilities. Using a modal representation of the structure, a set of differential or differential-algebraic equations are derived for general thin structures with geometric nonlinearities. ODEPACK and LAPACK routines are linked with FUN3D, and the nonlinear equations are solved at each CFD time step. The existing predictor-corrector method is retained, whereby the structural solution is updated after mesh deformation. The nonlinear solver is validated using a test case for a flexible aeroshell at transonic, supersonic, and hypersonic flow conditions. Agreement with linear theory is seen for the static aeroelastic solutions at relatively low dynamic pressures, but structural nonlinearities limit deformation amplitudes at high dynamic pressures. No flutter was found at any of the tested trajectory points, though LCO may be possible in the transonic regime.

The WYKO Corporation was founded on December 27, 1982 to design, manufacture, sell, and service metrology instruments for many applications, with the largest market being in the magnetic data storage industry. WYKO grew out of the research my students and I did at the Optical Sciences Center at the University of Arizona, but it's origins actually started earlier at the Itek Corporation where I went to work after getting my PhD in optics at the University of Rochester. Founding, growing, and cashing out was an unbelievable experience that was more fun than I ever dreamed anything could be. In this talk I will discuss the formation, growth, and eventual selling of the WYKO Corporation to Veeco in 1997. Both the fun parts and the not so fun parts will be discussed. The biggest surprises experienced and what I think are the most important factors in growing a successful high-tech company will be described.

A estabilidade dos PAHS em função da energia da radiação interestelar nas faixas UV e raios-X

A nebulosa CRL 618, uma proto-nebulosa planetária cuja nuvem molecular espessa envolve uma estrela B0, contém uma grande quantidade de C2H2 e CH4. Estas moléculas são consideradas os tijolos da criação de grandes moléculas carbonadas como os Hidrocarbonetos Policíclicos Aromáticos (PAHs). Esta nebulosa, por estar exposta a intensos campos de UV e Raios-X, é uma região de fotodissociação molecular que propicia a formação de novas moléculas, confirmada pela presença de C4H2 e C6H6 (Benzeno), que é a unidade básica dos PAHs. Atribui-se a esta família de moléculas orgânicas duas propriedades fundamentais, a resistência para sobreviver ao campo de radiação UV interestelar e a geração das bandas de emissão não identificadas (UIR) observadas no infravermelho. No entanto, alguns autores questionam a resistência dos PAHs ao campo de radiação UV interestelar. Empregando a técnica de Espectrometria de Massas por Tempo de Vôo, no modo de coincidência fotoelétron-fotoíon, estudamos a ionização e fragmentação das seguintes moléculas: Benzeno, Benzeno deuterado, Naftaleno, Antraceno e Fenantreno. Utilizamos uma fonte de Hélio monocromática em 21,21 eV (584,5 Å) e a radiação Síncroton do Laboratório Nacional de Luz Síncroton (LNLS) em diferentes energias nas proximidades da borda do C 1s ( 290 eV). Comprovamos a estabilidade dos PAHs sob ação de UV (21,21 eV), onde eles apresentam um baixo nível de fotodissociação, produzindo fragmentos ionizados com rendimento total na ordem de 5 por cento em relação ao íon molecular pai. Entretanto, em altas energias, na faixa de Raios-X, a quebra destas moléculas torna-se mais intensa, com a produção de muitos fragmentos. Como uma das rotas de fragmentação do Naftaleno é [(C10H8) = > (C6H6+) + (C4H2) + (e-)], e como temos as evidências observacionais da existência do C4H2 e C6H6 na nebulosa CRL 618, sugerimos que este ambiente também possui o Naftaleno.

FunTree: advances in a resource for exploring and contextualising protein function evolution.

PubMed

Sillitoe, Ian; Furnham, Nicholas

2016-01-04

FunTree is a resource that brings together protein sequence, structure and functional information, including overall chemical reaction and mechanistic data, for structurally defined domain superfamilies. Developed in tandem with the CATH database, the original FunTree contained just 276 superfamilies focused on enzymes. Here, we present an update of FunTree that has expanded to include 2340 superfamilies including both enzymes and proteins with non-enzymatic functions annotated by Gene Ontology (GO) terms. This allows the investigation of how novel functions have evolved within a structurally defined superfamily and provides a means to analyse trends across many superfamilies. This is done not only within the context of a protein's sequence and structure but also the relationships of their functions. New measures of functional similarity have been integrated, including for enzymes comparisons of overall reactions based on overall bond changes, reaction centres (the local environment atoms involved in the reaction) and the sub-structure similarities of the metabolites involved in the reaction and for non-enzymes semantic similarities based on the GO. To identify and highlight changes in function through evolution, ancestral character estimations are made and presented. All this is accessible through a new re-designed web interface that can be found at http://www.funtree.info. © The Author(s) 2015.

Why the public health sector couldn't create Pokémon Go.

PubMed

Freeman, Becky; Chau, Josephine; Mihrshahi, Seema

Pokémon Go has been subject to much attention - from both the players that download the augmented reality game and the news media. Amid the exaggerated media reports, Pokémon Go may have unintended health benefits. Players have reported walking more, spending more time with family, experiencing improvements in their mental health and feeling more connected to their communities. It is hard to imagine public health researchers developing a similar game that is fun, taps into pop culture, reaches a wide target audience, makes use of physical and virtual environments, creates a sense of both competition and community, and has spin-off health benefits. Companies that endanger public health immediately recognised the value of the Pokémon Go app, and exploited it to advertise and promote consumption of unhealthy foods. Public health stakeholders need to develop mobile-based interventions within a framework that embraces pleasure, rewards, participation and community. Public health agencies need to be just as nimble and responsive as companies that are harmful to health, or forever be creating games that nobody plays.

Quantum Chess: Making Quantum Phenomena Accessible

NASA Astrophysics Data System (ADS)

Cantwell, Christopher

Quantum phenomena have remained largely inaccessible to the general public. There tends to be a scare factor associated with the word ``Quantum''. This is in large part due to the alien nature of phenomena such as superposition and entanglement. However, Quantum Computing is a very active area of research and one day we will have games that run on those quantum computers. Quantum phenomena such as superposition and entanglement will seem as normal as gravity. Is it possible to create such games today? Can we make games that are built on top of a realistic quantum simulation and introduce players of any background to quantum concepts in a fun and mentally stimulating way? One of the difficulties with any quantum simulation run on a classical computer is that the Hilbert space grows exponentially, making simulations of an appreciable size physically impossible due largely to memory restrictions. Here we will discuss the conception and development of Quantum Chess, and how to overcome some of the difficulties faced. We can then ask the question, ``What's next?'' What are some of the difficulties Quantum Chess still faces, and what is the future of quantum games?

Pretend play.

PubMed

Weisberg, Deena Skolnick

2015-01-01

Pretend play is a form of playful behavior that involves nonliteral action. Although on the surface this activity appears to be merely for fun, recent research has discovered that children's pretend play has connections to important cognitive and social skills, such as symbolic thinking, theory of mind, and counterfactual reasoning. The current article first defines pretend play and then reviews the arguments and evidence for these three connections. Pretend play has a nonliteral correspondence to reality, hence pretending may provide children with practice with navigating symbolic relationships, which may strengthen their language skills. Pretend play and theory of mind reasoning share a focus on others' mental states in order to correctly interpret their behavior, hence pretending and theory of mind may be mutually supportive in development. Pretend play and counterfactual reasoning both involve representing nonreal states of affairs, hence pretending may facilitate children's counterfactual abilities. These connections make pretend play an important phenomenon in cognitive science: Studying children's pretend play can provide insight into these other abilities and their developmental trajectories, and thereby into human cognitive architecture and its development. © 2015 John Wiley & Sons, Ltd.

SUMMARY Involving low-income, ethnic minority families in lengthy HIV prevention programs can be challenging. Understanding the motivators and barriers to involvement may help researchers and practitioners design programs that can be used by populations most at risk for HIV exposure. The present study discusses motivators and barriers to involvement in the Collaborative HIV Prevention and Adolescent Mental Health Project (CHAMP), using data from a sample of 118 families that participated at varying levels in the twelve sessions of the program. Most participants chose motivators that reflect their perceptions of individual and/or family needs (“CHAMP might help me, mine, and other families”), and of characteristics of the program, such as CHAMP staff were friendly, CHAMP was fun. Among barriers to involvement, respondents expressed concerns about confidentiality, and about being judged by program staff. Respondents also reported experiencing many stressful events in their families (e.g., death and violence in the family) that may have been barriers to their involvement. Knowing these motivators and barriers, researchers and practitioners can enhance involvement in HIV prevention programs. PMID:20686648

Ketamine and ethanol are increasingly being used together as recreational drugs in rave parties. Their effects on the dopamine (DA) system remain largely unknown. This study aimed to investigate the effects of consuming two different concentrations of ketamine with and without alcohol on the DA system. We employed the conditioned place preference (CPP) paradigm to evaluate the rewarding effects of the combined administration of two different doses of ketamine (30mg/kg and 60mg/kg) with ethanol (0.3156g/kg). We evaluated the effects of the combined drug treatment on the transcriptional output of tyrosine hydroxylase (TH), dopa decarboxylase (DDC), synaptosomal-associated protein 25 (SNAP25), and vesicular monoamine transporter 2 (VMAT2) as well as protein expression level of brain-derived neurotrophic factor (BDNF) in rat prefrontal cortex (PFC) and striatum. We found that rats exhibited a dose-dependent, drug-paired, place preference to ketamine and ethanol associated with an elevated DA level in the striatum but not in the PFC. Moreover, treatment involving low- or high-dose ketamine with or without ethanol caused a differential regulatory response in the mRNA levels of the four DA metabolism genes and the cellular protein abundance of BDNF via the cortex-striatum circuitry. This study investigated the molecular mechanisms that occur following the combined administration of ketamine and ethanol in the DA system, which could potentially lead to alterations in the mental status and behavior of ketamine/ethanol users. Our findings may aid the development of therapeutic strategies for substance abuse patients. Copyright © 2017 Elsevier Inc. All rights reserved.

The deficit in ability to attribute mental states such as thoughts, beliefs, and intentions of another person is a key component in the functional impairment of social cognition in schizophrenia. In the current study, we compared the ability of persons with first episode schizophrenia (FE-SZ) and individuals with schizophrenia displaying symptomatic remission (SZ-CR) to decode the mental state of others with healthy individuals and schizoaffective patients. In addition, we analyzed the effect of dopamine-related genes polymorphism on the ability to decode the mental state of another, and searched for different genetic signatures. Our results show that overall, individuals with schizophrenia performed worse in the "Reading the Mind in the Eyes" (eyes) test, a simple well-defined task to infer the mental state of others than healthy individuals. Within the schizophrenia group, schizoaffective scored significantly higher than FE-SZ, SZ-CR, and healthy individuals. No difference was observed in performance between FE-SZ and SZ-CR subjects. Interestingly, FE-SZ and SZ-CR, but not schizoaffective individuals, performed worse in decoding negative and neutral emotional valance than the healthy control group. At the genetic level, we observed a significant effect of the DAT genotype, but not D4R genotype, on the eyes test performance. Our data suggest that understanding the mental state of another person is a trait marker of the illness, and might serve as an intermediate phenotype in the diagnostic process of schizophrenia disorders, and raise the possibility that DA-related DAT gene might have a role in decoding the mental state of another person.

2017-01-01

An aeroelastic analysis of a prototype distributed electric propulsion wing is presented. Results using MSC Nastran (Registered Trademark) doublet lattice aerodynamics are compared to those based on FUN3D Reynolds Averaged Navier- Stokes aerodynamics. Four levels of grid refinement were examined for the FUN3D solutions and solutions were seen to be well converged. It was found that no oscillatory instability existed, only that of divergence, which occurred in the first bending mode at a dynamic pressure of over three times the flutter clearance condition.

There has been a debate about whether entertainment videogames should incorporate story or narrative. A concern has been whether story cut scenes break game immersion, and thereby minimize the fun of gameplay. Alternatively, games for health (G4H) have an agenda that goes beyond just having fun. The possible role of story in G4H has not been thoroughly addressed. We have assembled a group of experts who have worked with stories in G4H, and asked some pointed questions. PMID:26196925

Telemedicine has been seen as an important tool for facing the challenges of universal health systems. The goal of this article is to discuss the main challenges to its full dissemination in Brazil. Being a somewhat new area, there are not many scientific papers that systematize it. This article is an exploratory paper, as it aims to provide an overall perspective on the subject. From an economic point of view, telemedicine is a strategic area due to its an intrinsic potential of being a source for generating innovation, for requiring and incorporating technological breakthroughs from other areas, and for its interdisciplinary nature and dynamic inter-relations that drive different industries. From the social perspective, it has the potential to make access to health services democratic, by connecting remote regions with health services located in hospitals and centers of reference for prevention, diagnosis and treatment. Resumo: A telemedicina está sendo vista como uma ferramenta importante para enfrentar os desafios dos sistemas de saúde universais. O objetivo deste artigo foi discutir os principais desafios para a sua plena disseminação no Brasil. Em função do caráter relativamente emergente desta área, existe uma escassez relativa de trabalhos científicos que a sistematizem. Por isso, este artigo se enquadra na categoria de trabalho exploratório, já que tem por objetivo proporcionar uma visão geral sobre o tema. Destaca-se, que do ponto de vista econômico, a telemedicina se constitui em uma área estratégica por seu potencial intrínseco de ser fonte geradora de inovações, por demandar e incorporar avanços tecnológicos oriundos de outras áreas e, em função da sua natureza interdisciplinar e de suas inter-relações dinâmicas, pela possibilidade de impulsionar diferentes indústrias. Do ponto de vista social, tem o potencial de democratizar o acesso aos serviços de saúde, integrando regiões remotas com serviços de saúde localizados em hospitais e centros de referência no que se refere à prevenção, diagnóstico e tratamento.

The objective of this research was to assess the psychometric properties of the Sport Satisfaction Instrument (SSI) in a Spanish sample of female athletes in team sports federations, to decide whether it constitutes a valid and reliable instrument to be used in the context of female competitive sport in future research. The SSI was administered to a total of 615 athletes from 12 to 38 yr. of age. Confirmatory procedures and psychometric analysis supported the hypothesized theoretical model of two factors (Satisfaction/fun and Boredom). For female athletes, the 7-item model showed better goodness-of-fit indexes upon eliminating Item 2 from the Boredom subscale. Concurrent validity was explored through the correlations with the Perception of Success Questionnaire and Sport Commitment, obtaining positive correlations between Satisfaction/fun and Task Orientation and Sport Commitment, whereas Boredom correlated positively but less closely with Ego Orientation. The importance of Satisfaction/fun in the prediction of Sport Commitment, starting from task orientation, is emphasized.

The purpose of this study was to examine the effectiveness of the Cognitive-Functional (Cog-Fun) intervention for young children with attention deficit hyperactivity disorder (ADHD). Nineteen children ages 5-7 yr diagnosed with ADHD were allocated to treatment and wait-list control groups. After the 12-wk intervention, the control group was crossed over to treatment. Follow-up was conducted 3 mo after treatment. Outcome measures included the Behavior Rating Inventory of Executive Function and the Canadian Occupational Performance Measure. Before crossover, significant differences were found between groups in change scores on the outcome measures. After crossover, no significant differences were found in treatment effects, and significant moderate to large treatment effects were found for both COPM and BRIEF scores. Treatment gains were maintained at follow-up. The study supports the effectiveness of the Cog-Fun intervention in improving occupational performance and executive functions in daily life for young children with ADHD.

2012-01-01

Numerical simulations have been performed for a partially-dressed, cavity-closed nose landing gear configuration that was tested in NASA Langley s closed-wall Basic Aerodynamic Research Tunnel (BART) and in the University of Florida s open-jet acoustic facility known as UFAFF. The unstructured-grid flow solver, FUN3D, developed at NASA Langley Research center is used to compute the unsteady flow field for this configuration. A hybrid Reynolds-averaged Navier-Stokes/large eddy simulation (RANS/LES) turbulence model is used for these computations. Time-averaged and instantaneous solutions compare favorably with the measured data. Unsteady flowfield data obtained from the FUN3D code are used as input to a Ffowcs Williams-Hawkings noise propagation code to compute the sound pressure levels at microphones placed in the farfield. Significant improvement in predicted noise levels is obtained when the flowfield data from the open jet UFAFF simulations is used as compared to the case using flowfield data from the closed-wall BART configuration.

2008-01-01

Functional similarity based on Gene Ontology (GO) annotation is used in diverse applications like gene clustering, gene expression data analysis, protein interaction prediction and evaluation. However, there exists no comprehensive resource of functional similarity values although such a database would facilitate the use of functional similarity measures in different applications. Here, we describe FunSimMat (Functional Similarity Matrix, http://funsimmat.bioinf.mpi-inf.mpg.de/), a large new database that provides several different semantic similarity measures for GO terms. It offers various precomputed functional similarity values for proteins contained in UniProtKB and for protein families in Pfam and SMART. The web interface allows users to efficiently perform both semantic similarity searches with GO terms and functional similarity searches with proteins or protein families. All results can be downloaded in tab-delimited files for use with other tools. An additional XML–RPC interface gives automatic online access to FunSimMat for programs and remote services.

2006-01-01

Two gradient-based adaptation methodologies have been implemented into the Fun3d refine GridEx infrastructure. A spring-analogy adaptation which provides for nodal movement to cluster mesh nodes in the vicinity of strong shocks has been extended for general use within Fun3d, and is demonstrated for a 70 sphere cone at Mach 2. A more general feature-based adaptation metric has been developed for use with the adaptation mechanics available in Fun3d, and is applicable to any unstructured, tetrahedral, flow solver. The basic functionality of general adaptation is explored through a case of flow over the forebody of a 70 sphere cone at Mach 6. A practical application of Mach 10 flow over an Apollo capsule, computed with the Felisa flow solver, is given to compare the adaptive mesh refinement with uniform mesh refinement. The examples of the paper demonstrate that the gradient-based adaptation capability as implemented can give an improvement in solution quality.

Collaborate and share: an experimental study of the effects of task and reward interdependencies in online games.

Today millions of players interact with one another in online games, especially massively multiplayer online role-playing games (MMORPGs). These games promote interaction among players by offering interdependency features, but to date few studies have asked what interdependency design factors of MMORPGs make them fun for players, produce experiences of flow, or enhance player performance. In this study, we focused on two game design features: task and reward interdependency. We conducted a controlled experiment that compared the interaction effects of low and high task-interdependency conditions and low and high reward-interdependency conditions on three dependent variables: fun, flow, and performance. We found that in a low task-interdependency condition, players had more fun, experienced higher levels of flow, and perceived better performance when a low reward-interdependency condition also obtained. In contrast, in a high task-interdependency condition, all of these measures were higher when a high reward-interdependency condition also obtained.

The goal of this research is to use the University of Wyoming’s Red Buttes Observatory (RBO) to perform manual, remote, or automated observations of transiting exoplanet candidates. The data contributes to discovery of star systems that include never before identified exoplanets. RBO houses a 0.6-meter telescope and is located approximately 10 miles south of the University of Wyoming’s campus. Our targets are catalogued by the KELT (Kilodegree Extremely Little Telescope) Survey, a photometric search for transiting exoplanets around bright main sequence stars. The KELT Follow-up Network (KELT-FUN), a collaboration of small-aperture telescope users located all over the world, confirms new exoplanet candidates. As part of KELT-FUN, students use the RBO to monitor candidates identified by the KELT team. RBO typically detects transits around stars that are 8-12 in V magnitude, with transit durations of ~1-4 hours and full depth relative changes in brightness above 2 mmags. Using AstroImageJ, we process the data and we look for any indication of a transit occurrence in the processed lightcurve which might confirm the presence of the potential exoplanet. Our team has contributed over 50 light curves to KELT-FUN to date. We are able to compare our data with simultaneous observations by other members of KELT-FUN to maximize the utility of our observations. This project gives undergraduates an authentic scientific research experience, learning how to operate an observatory, process data, and participate in a scientific collaboration.

Suitability of a structured Fundamental Movement Skills program for long day care centres: a process evaluation.

2009-04-01

Early childhood presents an opportunity to encourage development of Fundamental Movement Skills (FMS). Implementation of a structured program in the Long Day Care (LDC) setting presents challenges. Implementation of a structured FMS program FunMoves was assessed in LDC in metropolitan New South Wales. LDC staff attended a training session conducted by trained Health Promotion Officers (HPOs) and completed an evaluation. During implementation HPOs completed lesson observations. De-identified attendance data was collected and director and staff feedback on the program including barriers to implementation was obtained via questionnaire. Qualitative information relevant to process evaluation was obtained via open questions on questionnaires, and a de-brief diary recording feedback from directors and staff. Knowledge of FMS and FunMoves and staff confidence to deliver the program were high after training. On average, staff stated they ran lessons more than the suggested twice weekly and the majority of children attended 1-3 lessons per week. However, lesson delivery was not as designed, and staff found FunMoves disruptive and time consuming. Six directors and the majority of staff thought that FunMoves could be improved. Structured program delivery was hampered by contextual issues including significant staff turnover and program length and structure being at odds with the setting. Implementation could be enhanced by guidelines for more flexible delivery options including less structured approaches, shorter and simpler lessons, ongoing conversations with the early childhood sector, in-centre engagement of staff and post-training support.

Healthy habits are no fun: How Dutch youth negotiate discourses about food, fit, fat, and fun.

PubMed

van Amsterdam, Noortje; Knoppers, Annelies

2018-03-01

In this article, we use the notion of "biopedagogical practices" to explore how Dutch youth respond to health messages that focus on body weight. Previous studies suggest that such health messages encourage body dissatisfaction in youth. Few studies, however, focus on the local/cultural specificity of youth's responses to these biopedagogical practices. In this article, we address questions about the re-interpretation of and resistance to health messages that Dutch youth engage in and how these can be understood in their local context. The data were drawn from two previously conducted studies in which a total of 64 Dutch teenagers (aged 12-18 years) took part. We employed a variety of qualitative data collection methods and a feminist poststructuralist perspective to analyze how Dutch youth negotiate biopedagogical practices about health. The results show that our participants constructed health in terms of appearance and reproduced negative constructions regarding fat embodiment. Yet they also often circumvented "healthy" lifestyle behaviors prescribed by biopedagogies of health. They did so first by avoiding physical activities because they were afraid of displaying fat embodiment in the settings of sport and physical education where surveillance is omnipresent. Second, they disregarded advice about healthy eating by drawing on having fun as an alternative discursive resource. We argue that having fun is both part of youth culture and characteristic of the discourse about sociability ( gezelligheid) that is a central element of Dutch culture.

An Inhalable Powder Formulation Based on Micro- and Nanoparticles Containing 5-Fluorouracil for the Treatment of Metastatic Melanoma

Melanoma is the most aggressive and lethal type of skin cancer, with a poor prognosis because of the potential for metastatic spread. The aim was to develop innovative powder formulations for the treatment of metastatic melanoma based on micro- and nanocarriers containing 5-fluorouracil (5FU) for pulmonary administration, aiming at local and systemic action. Therefore, two innovative inhalable powder formulations were produced by spray-drying using chondroitin sulfate as a structuring polymer: (a) 5FU nanoparticles obtained by piezoelectric atomization (5FU-NS) and (b) 5FU microparticles of the mucoadhesive agent Methocel™ F4M for sustained release produced by conventional spray drying (5FU-MS). The physicochemical and aerodynamic were evaluated in vitro for both systems, proving to be attractive for pulmonary delivery. The theoretical aerodynamic diameters obtained were 0.322 ± 0.07 µm (5FU-NS) and 1.138 ± 0.54 µm (5FU-MS). The fraction of respirable particles (FR%) were 76.84 ± 0.07% (5FU-NS) and 55.01 ± 2.91% (5FU-MS). The in vitro mucoadhesive properties exhibited significant adhesion efficiency in the presence of Methocel™ F4M. 5FU-MS and 5FU-NS were tested for their cytotoxic action on melanoma cancer cells (A2058 and A375) and both showed a cytotoxic effect similar to 5FU pure at concentrations of 4.3 and 1.7-fold lower, respectively.

Leonardo da Vinci's "A skull sectioned": skull and dental formula revisited.

PubMed

Gerrits, Peter O; Veening, Jan G

2013-05-01

What can be learned from historical anatomical drawings and how to incorporate these drawings into anatomical teaching? The drawing "A skull sectioned" (RL 19058v) by Leonardo da Vinci (1452-1519), hides more detailed information than reported earlier. A well-chosen section cut explores sectioned paranasal sinuses and ductus nasolacrimalis. A dissected lateral wall of the maxilla is also present. Furthermore, at the level of the foramen mentale, the drawing displays compact and spongious bony components, together with a cross-section through the foramen mentale and its connection with the canalis mandibulae. Leonardo was the first to describe a correct dental formula (6424) and made efforts to place this formula above the related dental elements. However, taking into account, the morphological features of the individual elements of the maxilla, it can be suggested that Leonardo sketched a "peculiar dental element" on the position of the right maxillary premolar in the dental sketch. The fact that the author did not make any comment on that special element is remarkable. Leonardo could have had sufficient knowledge of the precise morphology of maxillary and mandibular premolars, since the author depicted these elements in the dissected skull. The fact that the author also had access to premolars in situ corroborates our suggestion that "something went wrong" in this part of the drawing. The present study shows that historical anatomical drawings are very useful for interactive learning of detailed anatomy for students in medicine and dentistry.

To update knowledge and methods to access and view the journals included in Qualis of CAPES Medicine III, and how to measure the impact factor. Document review on the attempt to verify the way Qualis uses for ranking journals cited by the post-graduate programs of Medicine III in their evaluation periods, and the impact factors obtained by journals indexing base. The classification is annual and are ranking in strata ranging from A1, the highest, and A2; B1; B2; B3; B4; B5; C. The latter has zero evaluation weight. These strata take as reference the impact factor of the journals listed by the programs. The same journal can be classified into different Qualis in other areas, and this is no inconsistency, but expressed the assigned value, in each area, at that particular journal. The Impact Factor is measured using the Journal of Citation Report in Web of Knowledge website. Using the criteria established by WebQualis for stratification of journals there is a quality guidance of what is produced by the program and, based on it, can be made scientific comparison of program performance. Consulting the JCR is recommended because it defines exactly what is the journal's impact factor; Qualis stratifies numerical intervals and not individual journal specificity. Atualização do conhecimento dos meios e métodos de acessar e visualizar os periódicos do Qualis da Medicina III da CAPES e a mensuração do Fator de Impacto. Buscou-se verificar a forma utilizada pelo Qualis para classificar os periódicos referidos pelos programas de pós-graduação da Medicina III em seus períodos de avaliação e os fatores de impacto obtidos pelas revistas em base indexadora. A classificação é anual e são enquadrados em estratos que variam de A1, o mais elevado, a A2; B1; B2; B3; B4; B5; C. Este último tem peso zero. Esses estratos levam como referência o Fator de Impacto dos periódicos referidos pelos programas. Um mesmo periódico pode ter classificação em Qualis diferentes em outras áreas, e isto não constitui inconsistência, mas expressa o valor atribuído, em cada área, àquela determinada revista científica. O Fator de Impacto é mensurado navegando-se no site do Journal of Citation Report da Web of Knowledge. A utilização dos critérios estabelecidos pelo WebQualis para estratificação dos periódicos é norteadora da qualidade do que se produz nos programas e, com base nela, pode-se fazer comparações de desempenho científico. Já a consulta ao JCR é complementarmente adequada de ser feita porque define com exatidão qual é o fator de impacto da revista, em função de que o Qualis estratifica faixas numéricas e não especificidade individual do periódico.

Results are presented on a detailed petrologic, chemical, and isotopic study of the so-called FUN inclusion (1623-5) from the Vigarano C3V chondrite. It is shown that the precursor material from which the Vigarano 1623-5 has formed contained some nuclear isotopic anomalies; this precursor was composed of melted and crystallized spinel, olivine, fassaite, and melilite. The results on the petrologic and isotopic properties of 1623-5 indicate unambiguously the action of volatilization in the evolution of this inclusion.

To verify the effects of antihypertensive treatment (pharmacological and non-pharmacological) on the health-related quality of life of individuals with hypertension. We conducted a systematic review with meta-analysis using the following databases: IBECS, LILACS, SciELO, Medline, Cochrane, Science Direct, Scopus and the Brazilian Capes Theses and Dissertations Database. The statistical analysis was performed using Review Manager, version 5.2. The average difference was used for the summarization of meta-analytic effect by the fixed-effect model. Twenty studies were included. The summarization of the effect showed an average increase of 2.45 points (95%CI 1.02-3.87; p < 0.0008) in the quality of life of individuals adhering to non-pharmacological treatment for arterial hypertension. Adherence to pharmacological treatment indicated an average increase of 9.24 points (95%CI 8.16-10.33; p < 0.00001) in the quality of life of individuals with arterial hypertension. Non-pharmacological treatment improves the overall quality of life and physical domain of people with arterial hypertension. Adherence to pharmacological treatment has a positive impact on the mental and physical domains of patients, as it did on the overall quality of life score.

More than ten percent of people suffer from at least one episode of depression and related mental disorders in a lifetime, and depression and related mental disorders are one of the world's greatest public health problems. A multiple system theory holds that dysregulation of the multiple systems underlies the pathogenesis of depression and related mental disorders, and new therapies based on the multiple system dysregulation theory are urgently needed. In this study, the antidepressant effect of decoction from herb Cistanche deserticola Y.C.Ma and Cistanche tubulosa was examined. Herb Cistanche decoction reduced the immobility period significantly in the mouse tail suspension test. Mice treated with herb decoction showed an improved ability of spatial learning and memory in the Morris water maze test. Groups treated herb decoction displayed a downregulated monoamine oxidase (MAO) activity; the dopamine (DA) concentration in the brain was upregulated, indicating herb Cistanche decoction improved the nerve excitability; the serum concentration of corticosterone (CORT) was downregulated, showing that mice benefited from a reduced stress level. Hence, the antidepressant efficacy and mechanism of traditional Chinese herb Cistanche were explored in this study. Herb Cistanche showed a potential to be developed as a complementary and alternative therapy for depression. PMID:28744316

In this study, a methodology based on Fourier-transform infrared spectroscopy and principal component analysis and partial least square methods is proposed for the analysis of blood plasma samples in order to identify spectral changes correlated with some biomarkers associated with schizophrenia and bipolarity. Our main goal was to use the spectral information for the calibration of statistical models to discriminate and classify blood plasma samples belonging to bipolar and schizophrenic patients. IR spectra of 30 samples of blood plasma obtained from each, bipolar and schizophrenic patients and healthy control group were collected. The results obtained from principal component analysis (PCA) show a clear discrimination between the bipolar (BP), schizophrenic (SZ) and control group' (CG) blood samples that also give possibility to identify three main regions that show the major differences correlated with both mental disorders (biomarkers). Furthermore, a model for the classification of the blood samples was calibrated using partial least square discriminant analysis (PLS-DA), allowing the correct classification of BP, SZ and CG samples. The results obtained applying this methodology suggest that it can be used as a complimentary diagnostic tool for the detection and discrimination of these mental diseases.

Over the years, incisional hernia repair has evolved. Currently, primary closure of the defect before placing the mesh is a critical step in incisional hernia repair and minimally invasive surgery incorporation has an important role due to great advantages. Despite its benefits, laparoscopic closure with suture intracorporeal knotting is physically demanding and technically complex. Robotic technology provides an optimal three-dimensional view, maneuverability of the instruments but no study has assessed the impact of the DaVinci system in the ergonomics which is the objective in this study. Fourteen surgeons were able to achieve surgical repair of a defect in an incisional hernia inanimate model. The task was performed with conventional laparoscopy and robotic assistance. The mental effort was registered and physical disturbances were measured with the Local Experienced Discomfort scale. The subjects expressed discomfort mainly in the dominant side (p = 0.006). In the comparative analysis between the two approaches, upper limb less disturbance (p = 0.04) and lower mental effort (p = 0.001) were reported with robotic approach. Robotic assistance decreases mental and physical effort during the primary closure of a defect in an incisional hernia inanimate model.

Gamification has been incorporated into vision tests and vision therapies in the expectation that it may increase the user experience and engagement with the task. The current study aimed to understand how gamification affects the user experience, specifically during the undertaking of psychophysical tasks designed to estimate vision thresholds (chromatic and achromatic contrast sensitivity). Three tablet computer-based games were developed with three levels of gaming elements. Game 1 was designed to be a simple clinical test (no gaming elements), game 2 was similar to game 1 but with added gaming elements (i.e., feedback, scores, and sounds), and game 3 was a complete game. Participants (N = 144, age: 9.9-42 years) played three games in random order. The user experience for each game was assessed using a Short Feedback Questionnaire. The median (interquartile range) fun level for the three games was 2.5 (1.6), 3.9 (1.7), and 2.5 (2.8), respectively. Overall, participants reported greater fun level and higher preparedness to play the game again for game 2 than games 1 and 3 (P < 0.05). There were significant positive correlations observed between fun level and preparedness to play the game again for all the games (p < 0.05). Engagement (assessed as completion rates) did not differ between the games. Gamified version (game 2) was preferred to the other two versions. Over the short term, the careful application of gaming elements to vision tests was found to increase the fun level of users, without affecting engagement with the vision test.

The demands on leisuretime activities are getting more exacting. So trendy sports just like inline-skating, mountain-biking, paragliding, bungee-jumping or driving go karts become increasing popular. On the other side risks and injuries of this fun sports are not enough represented. We observed in a 16 months period 5 serious accidents with go karts. The injuries included bruise of lower leg, a contusion of the stomach with a pancreatic lesion, an instable fracture of the spinal column, a difficult fracture of the knee and upper tibia and a large sized burnwound. The mean hospitalization time was 32,5 days (17-54 days) and the average age of the patients 27,7 years (9-45 years). The lack of safety devices and the subjective inexperience make go kart driving a dangerous fun. The TUV worked out guidelines for security of indoor kart centres but they don't have any legal liability in case of injury. Therefore everyone carrying out fun sports like go kart driving should be aware of the dangers and should gather information whether the accident insurance will help out in case of injury.

The origin of the 'FUN' anomalies and the high temperature inclusions in the Allende meteorite. [Fractionation and Unknown Nuclear processes

Consolmagno, G. J.; Cameron, A. G. W.

1980-01-01

The discovery of isotopic anomalies in white inclusions of the meteorite Allende has led to fundamental questions concerning the origin of these anomalies and of the white inclusions themselves. An analysis of the 'FUN' anomalies in the inclusions C1 and EK1-4-1 demonstrates that these isotopic anomalies may be decomposed into individual nucleosynthetic components, which have been subjected to separate mass and component fractionations. There is no evidence that any freshly-synthesized material injected into the primitive solar nebula was of abnormal isotopic composition, or that the FUN anomalies were due to an injection of unusual material. Rather, they show the effects of large mass fractionations and an unusual mixture of normal nucleosynthetic material, likely to be in the form of interstellar grains whose size or chemistry served as a memory for the nucleosynthetic origins of their constituent atoms. Giant gaseous protoplanets, as described for the early solar nebula by Cameron (1978), are a potential site for achieving both mass and component fractionations, and for producing white inclusions in general.

Structure of the Fibrillin-1 N-Terminal Domains Suggests that Heparan Sulfate Regulates the Early Stages of Microfibril Assembly

Summary The human extracellular matrix glycoprotein fibrillin-1 is the primary component of the 10- to 12-nm-diameter microfibrils, which perform key structural and regulatory roles in connective tissues. Relatively little is known about the molecular mechanisms of fibrillin assembly into microfibrils. Studies using recombinant fibrillin fragments indicate that an interaction between the N- and C-terminal regions drives head-to-tail assembly. Here, we present the structure of a fibrillin N-terminal fragment comprising the fibrillin unique N-terminal (FUN) and the first three epidermal growth factor (EGF)-like domains (FUN-EGF3). Two rod-like domain pairs are separated by a short, flexible linker between the EGF1 and EGF2 domains. We also show that the binding site for the C-terminal region spans multiple domains and overlaps with a heparin interaction site. These data suggest that heparan sulfate may sequester fibrillin at the cell surface via FUN-EGF3 prior to aggregation of the C terminus, thereby regulating microfibril assembly. PMID:24035709

Radiation Coupling with the FUN3D Unstructured-Grid CFD Code

The HARA radiation code is fully-coupled to the FUN3D unstructured-grid CFD code for the purpose of simulating high-energy hypersonic flows. The radiation energy source terms and surface heat transfer, under the tangent slab approximation, are included within the fluid dynamic ow solver. The Fire II flight test, at the Mach-31 1643-second trajectory point, is used as a demonstration case. Comparisons are made with an existing structured-grid capability, the LAURA/HARA coupling. The radiative surface heat transfer rates from the present approach match the benchmark values within 6%. Although radiation coupling is the focus of the present work, convective surface heat transfer rates are also reported, and are seen to vary depending upon the choice of mesh connectivity and FUN3D ux reconstruction algorithm. On a tetrahedral-element mesh the convective heating matches the benchmark at the stagnation point, but under-predicts by 15% on the Fire II shoulder. Conversely, on a mixed-element mesh the convective heating over-predicts at the stagnation point by 20%, but matches the benchmark away from the stagnation region.

Individuals benefit from occupying central roles in social networks, but little is known about the psychological traits that predict centrality. Across four college freshman dorms ( n = 193), we characterized individuals with a battery of personality questionnaires and also asked them to nominate dorm members with whom they had different types of relationships. This revealed several social networks within dorm communities with differing characteristics. In particular, additional data showed that networks varied in the degree to which nominations depend on ( i ) trust and ( ii ) shared fun and excitement. Networks more dependent upon trust were further defined by fewer connections than those more dependent on fun. Crucially, network and personality features interacted to predict individuals' centrality: people high in well-being (i.e., life satisfaction and positive emotion) were central to networks characterized by fun, whereas people high in empathy were central to networks characterized by trust. Together, these findings provide network-based corroboration of psychological evidence that well-being is socially attractive, whereas empathy supports close relationships. More broadly, these data highlight how an individual's personality relates to the roles that they play in sustaining their community.

A nonintrusive point collocation method is used to propagate parametric uncertainties of the flexible Common Research Model, a generic transport configuration, through the unsteady aeroelastic CFD solver FUN3D. A range of random input variables are considered, including atmospheric flow variables, structural variables, and inertial (lumped mass) variables. UQ results are explored for a range of output metrics (with a focus on dynamic flutter stability), for both subsonic and transonic Mach numbers, for two different CFD mesh refinements. A particular focus is placed on computing failure probabilities: the probability that the wing will flutter within the flight envelope.

The growing field of new technologies offers new ways to tackle psychiatric disorders (e.g. virtual reality therapy, neurofeedback, etc.). Serious games (SG) are computer applications combining serious aspects with the fun side of video games. This kind of new media could find applications to treat psychiatric disorders. This paper summarizes available data in the literature about therapeutic interventions using SG in psychiatry. A Medline search was conducted in May 2014 using the following Medical Subject Headings (MESH) terms: "video games", "mental disorders", and "psychotherapy". Only 10 relevant references were identified according to our inclusion criteria. These studies show that SG are very interesting tools to improve the management of psychiatric disorders. However, only low-level evidence is available to support treatment with SG in patients suffering from psychiatric disorders. Indeed, randomized controlled trials are rare in this field of research. SG provide promising therapeutic innovations for the management of psychiatric disorders. Moreover, they could easily be developed in accordance with current dimensional approaches. Finally, major issues to facilitate the implementation of future work on SG in psychiatry are discussed. Copyright © 2016 L'Encéphale, Paris. Published by Elsevier Masson SAS. All rights reserved.

Recruiting future neuroscientists: what asking the recruits can teach us.

Many different strategies are used to recruit students into scientific research careers, including neuroscience research. These strategies are rarely based on knowledge about students; instead, activities are selected based on their ease of implementation. The goal of the LEARN Project is to encourage high school students into mental health science research using the theme of learning and memory. One intervention the authors developed is five Web-based biographies introducing students to contemporary neuroscientist role models studying learning and memory. To guide the design of this intervention, the authors created a survey to determine where students obtain career information and who and what influences their career selection. In a convenience sample of 124 students, the authors found that almost all students use the Internet for information about careers, in addition to consulting family members and teachers. Students' career selections are influenced most by family members, teachers, and people already in the field. The most important factors students look for in their future career are money, fun, and a good match between current interests and future careers. The data affirm the value of outreach efforts that go beyond students to include a broader audience of parents and teachers who play a critical role in career selection.

The fragile X mental retardation protein (FMRP) is an RNA-binding protein that controls translational efficiency and regulates synaptic plasticity. Here, we report that FMRP is involved in dopamine (DA) modulation of synaptic potentiation. AMPA glutamate receptor subtype 1 (GluR1) surface expression and phosphorylation in response to D1 receptor stimulation were reduced in cultured Fmr1(-/-) prefrontal cortex (PFC) neurons. Furthermore, D1 receptor signaling was impaired, accompanied by D1 receptor hyperphosphorylation at serine sites and subcellular redistribution of G protein-coupled receptor kinase 2 (GRK2) in both PFC and striatum of Fmr1(-/-) mice. FMRP interacted with GRK2, and pharmacological inhibition of GRK2 rescued D1 receptor signaling in Fmr1(-/-) neurons. Finally, D1 receptor agonist partially rescued hyperactivity and enhanced the motor function of Fmr1(-/-) mice. Our study has identified FMRP as a key messenger for DA modulation in the forebrain and may provide insights into the cellular and molecular mechanisms underlying fragile X syndrome.

The ultraportable echocardiogram machine, with relevant portability and easiness in performing diagnoses, when in experienced hands, may contribute to the reliability of preoperative evaluation in noncardiac surgeries. To assess cardiac function parameters in patients aged older than 60 years, candidates of elective noncardiac surgeries, classified as ASA1 or ASA 2 according to surgical risk. A total of 211 patients referred for elective surgeries, without suspicion of previous heart diseases, were included in the study. Assessment of patients was conducted by conventional echocardiogram using the ultraportable V Scan (GE) device right after the pre-anesthetic clinical evaluation. We assessed the clinical impact of echocardiography results by using a questionnaire addressed to the anesthetist. Mean age of patients was 68.9 ± 7.0 years, 154 were women. The most frequent surgeries were: a) facectomy - cataract - 18; b) inguinal hernia surgery - 18; c) Cholecystectomy - 16. We found 58 normal tests (27.5%), 70 (33.2%) with mild valve reflux, and 83 (39.3%) with relevant abnormality, such as increase in heart chamber size, global and/or segmental contractile dysfunction, significant valve dysfunction or other unspecified. Test results caused delay of surgical procedure for a more detailed cardiac evaluation in 20 (9.5%) patients, and change in anesthetic management in 7 (3.3%). There was a considerable clinical impact with the use of the ultraportable echocardiography, since one out of every ten patients evaluated had their clinical management changed due to the detection of previously unsuspected, significant heart diseases, with the potential for severe complications. O ecocardiógrafo ultraportátil, com importante mobilidade e facilidade diagnóstica em mãos experientes pode contribuir para a segurança na avaliação pré-operatória em cirurgias não cardíacas.

Foram incluídos 211 pacientes direcionados para cirurgias eletivas diversas e sem suspeita prévia de cardiopatia. Os pacientes foram avaliados por técnica ecocardiográfica convencional, usando o aparelho ultraportátil V Scan (GE) logo após a avaliação clínica pré-anestésica. Avaliamos o impacto clínico dos resultados da ecocardiografia por um questionário dirigido ao anestesista. A idade média dos pacientes foi 68,9 ± 7,0 anos, 154 do sexo feminino. As cirurgias mais frequentes foram: a) Facectomia-catarata - 18; b) Herniorrafia inguinal - 18; c) Colecistectomia - 16. No total, foram observados 58 exames normais (27,5%), 70 (33,2%) exames que apresentavam leves refluxos valvares e 83 (39,3%) exames com alguma anormalidade relevante, como aumento de câmara cardíaca, disfunção contrátil global e/ou segmentar, disfunção valvar mais significativa ou outra não especificada. Os resultados determinaram que 20 (9,5%) pacientes tivessem seus procedimentos cirúrgicos adiados até avaliação cardiológica mais detalhada e em 7 (3,3%) houve mudança na conduta anestésica. Houve um impacto clínico considerável com o uso da ecocardiografia ultraportátil, pois um em cada dez pacientes avaliados sofreu modificação na conduta clínica, em função da detecção de cardiopatias significativas, não suspeitadas previamente, e com potencial para complicações graves.

Abstract Objective: Immersive virtual reality (VR) distraction provides clinically effective pain relief and increases subjective reports of “fun” in medical settings of procedural pain. The goal of this study was to better describe the variable of “fun” associated with VR distraction analgesia using the circumplex model (pleasure/arousal) of affect. Materials and Methods: Seventy-four healthy volunteers (mean age, 29 years; 37 females) received a standardized, 18-minute, multimodal pain sequence (alternating thermal heat and electrical stimulation to distal extremities) while receiving immersive, interactive VR distraction. Subjects rated both their subjective pain intensity and fun using 0–10 Graphic Rating Scales, as well as the pleasantness of their emotional valence and their state of arousal on 9-point scales. Results: Compared with pain stimulation in the control (baseline, no VR) condition, immersive VR distraction significantly reduced subjective pain intensity (P < 0.001). During VR distraction, compared with those reporting negative affect, subjects reporting positive affect did so more frequently (41 percent versus 9 percent), as well as reporting both greater pain reduction (22 percent versus 1 percent) and fun scores (7.0 ± 1.9 versus 2.4 ± 1.4). Several factors—lower anxiety, greater fun, greater presence in the VR environment, and positive emotional valence—were associated with subjective analgesia during VR distraction. Conclusions: Immersive VR distraction reduces subjective pain intensity induced by multimodal experimental nociception. Subjects who report less anxiety, more fun, more VR presence, and more positive emotional valence during VR distraction are more likely to report subjective pain reduction. These findings indicate VR distraction analgesia may be mediated through anxiolytic, attentional, and/or affective mechanisms. PMID:27171578

This paper presents preliminary computational aeroelastic analysis results generated in preparation for the first Aeroelastic Prediction Workshop (AePW). These results were produced using FUN3D software developed at NASA Langley and are compared against the experimental data generated during the HIgh REynolds Number Aero- Structural Dynamics (HIRENASD) Project. The HIRENASD wind-tunnel model was tested in the European Transonic Windtunnel in 2006 by Aachen University0s Department of Mechanics with funding from the German Research Foundation. The computational effort discussed here was performed (1) to obtain a preliminary assessment of the ability of the FUN3D code to accurately compute physical quantities experimentally measured on the HIRENASD model and (2) to translate the lessons learned from the FUN3D analysis of HIRENASD into a set of initial guidelines for the first AePW, which includes test cases for the HIRENASD model and its experimental data set. This paper compares the computational and experimental results obtained at Mach 0.8 for a Reynolds number of 7 million based on chord, corresponding to the HIRENASD test conditions No. 132 and No. 159. Aerodynamic loads and static aeroelastic displacements are compared at two levels of the grid resolution. Harmonic perturbation numerical results are compared with the experimental data using the magnitude and phase relationship between pressure coefficients and displacement. A dynamic aeroelastic numerical calculation is presented at one wind-tunnel condition in the form of the time history of the generalized displacements. Additional FUN3D validation results are also presented for the AGARD 445.6 wing data set. This wing was tested in the Transonic Dynamics Tunnel and is commonly used in the preliminary benchmarking of computational aeroelastic software.

Many children do not eat enough whole grains, which may have negative health consequences. Intervention research is increasingly focusing on nudging as a way to influence food choices by affecting unconscious behavioural processes. The aim of this field study was to examine whether the shape of bread rolls is able to shift children's bread choices from white to whole wheat during breakfast to increase whole grain intake. In a between-subjects experiment conducted at twelve primary schools in the Netherlands, with school as the unit of condition assignment, children were exposed to an assortment of white and whole wheat bread rolls, both varying in shape (regular versus fun). Children were free to choose the type and number of bread rolls and toppings to eat during breakfast. Consumption of bread rolls was measured at class level via the number of bread rolls before and after breakfast. In addition, children (N = 1113) responded to a survey including questions about the breakfast. Results of the field experiment showed that about 76% of bread consumption consisted of white bread rolls. Consumption of white bread rolls did not differ according to shape (all P-values > 0.18). However, presenting fun-shaped whole wheat bread rolls almost doubled consumption of whole wheat bread (P = 0.001), particularly when the simultaneously presented white bread rolls had a regular shape (interaction P = 0.02). Survey results suggest that slight increases in perceived pleasure and taste are associated with these effects. Overall, presenting whole wheat bread in fun shapes may be helpful in increasing consumption of whole wheat bread in children. Future research could examine how improving the visual appeal of healthy foods may lead to sustained behaviour changes.

A partir de 1998, entrou em operação regular no INPE, em São José dos Campos, o Brazilian Solar Spectroscope (BSS). O BSS é dedicado às observações de explosões solares decimétricas com alta resolução temporal e espectral, com a principal finalidade de investigar fenômenos associados com a liberação de energia dos "flares" solares. Entre os anos de 1999 e 2002, foram catalogadas, aproximadamente 340 explosões solares classificadas em 8 tipos distintos, de acordo com suas características morfológicas. Na análise detalhada de cada tipo, ou grupo, de explosões solares deve-se considerar a variação do fluxo do sol calmo ("background"), em função da freqüência e a variação temporal, além da complexidade das explosões e estruturas finas registradas superpostas ao fundo variável. Com o intuito de realizar tal análise foi desenvolvido o programa BSSData. Este programa, desenvolvido em linguagem C++, é constituído de várias ferramentas que auxiliam no tratamento e análise dos dados registrados pelo BSS. Neste trabalho iremos abordar as ferramentas referentes à filtragem do ruído de fundo. As rotinas do BSSData para filtragem de ruído foram testadas nos diversos grupos de explosões solares ("dots", "fibra", "lace", "patch", "spikes", "tipo III" e "zebra") alcançando um bom resultado na diminuição do ruído de fundo e obtendo, em conseqüência, dados onde o sinal torna-se mais homogêneo ressaltando as áreas onde existem explosões solares e tornando mais precisas as determinações dos parâmetros observacionais de cada explosão. Estes resultados serão apresentados e discutidos.

This document presents the development and application of unsteady aerodynamic, structural dynamic, and aeroelastic reduced-order models (ROMs) for the ascent aeroelastic analysis of the Ares I-X flight test and Ares I crew launch vehicles using the unstructured-grid, aeroelastic FUN3D computational fluid dynamics (CFD) code. The purpose of this work is to perform computationally-efficient aeroelastic response calculations that would be prohibitively expensive via computation of multiple full-order aeroelastic FUN3D solutions. These efficient aeroelastic ROM solutions provide valuable insight regarding the aeroelastic sensitivity of the vehicles to various parameters over a range of dynamic pressures.

Noise: My 62 years of it!

Imagine getting paid for having fun! Well, in retrospect, it was fun; but there were several tough challenges. Even those are worth remembering. From 1941 to 1982, there were acoustic torpedoes, HVAC acoustics, noise and vibration in auditoriums, aircraft and airport noise, OSHA and industrial noise control, power plants, community noise problems, vbration, railroad and subway vibration control, legal acoustics, noise manuals, and noise courses-and a few other things that don't fit into those neat categories. Some specific jobs could be named, but that would take away the suspense and the surprise. But 1941 to 1982 is only 41 years. How about the other 20-odd years?

A fun activity is presented using singing wine glasses for introductory physics students. Students tune a white wine glass and a red wine glass to as many semitones as possible by filling the glasses with the appropriate amounts of water. A smart phone app is used to measure the frequencies of equal-temperament tones. Then plots of frequency against water volume percent are made using a spreadsheet. Students can also play combinations of pitches with several glasses. A video (Ruiz 2018 Video: Singing glasses http://mjtruiz.com/ped/wineglasses/) is provided which includes an excerpt of a beautiful piece written for singing glasses and choir: Stars by Latvian composer Ēriks Ešenvalds.

IFCPT S-Duct Grid-Adapted FUN3D Computations for the Third Propulsion Aerodynamics Works

Davis, Zach S.; Park, M. A.

2017-01-01

Contributions of the unstructured Reynolds-averaged Navier-Stokes code, FUN3D, to the 3rd AIAA Propulsion Aerodynamics Workshop are described for the diffusing IFCPT S-Duct. Using workshop-supplied grids, results for the baseline S-Duct, baseline S-Duct with Aerodynamic Interface Plane (AIP) rake hardware, and baseline S-Duct with flow control devices are compared with experimental data and results computed with output-based, off-body grid adaptation in FUN3D. Due to the absence of influential geometry components, total pressure recovery is overpredicted on the baseline S-Duct and S-Duct with flow control vanes when compared to experimental values. An estimate for the exact value of total pressure recovery is derived for these cases given an infinitely refined mesh. When results from output-based mesh adaptation are compared with those computed on workshop-supplied grids, a considerable improvement in predicting total pressure recovery is observed. By including more representative geometry, output-based mesh adaptation compares very favorably with experimental data in terms of predicting the total pressure recovery cost-function; whereas, results computed using the workshop-supplied grids are underpredicted.

Individuals benefit from occupying central roles in social networks, but little is known about the psychological traits that predict centrality. Across four college freshman dorms (n = 193), we characterized individuals with a battery of personality questionnaires and also asked them to nominate dorm members with whom they had different types of relationships. This revealed several social networks within dorm communities with differing characteristics. In particular, additional data showed that networks varied in the degree to which nominations depend on (i) trust and (ii) shared fun and excitement. Networks more dependent upon trust were further defined by fewer connections than those more dependent on fun. Crucially, network and personality features interacted to predict individuals’ centrality: people high in well-being (i.e., life satisfaction and positive emotion) were central to networks characterized by fun, whereas people high in empathy were central to networks characterized by trust. Together, these findings provide network-based corroboration of psychological evidence that well-being is socially attractive, whereas empathy supports close relationships. More broadly, these data highlight how an individual’s personality relates to the roles that they play in sustaining their community. PMID:28851835

Childhood obesity remains a serious concern in the United States and in many other countries. Direct experience preparing and tasting healthful foods and increasing activity during the school day are promising prevention approaches. Engaging parents and families remains an important challenge. Fuel for Fun: Cooking with Kids Plus Parents and Play is a multi-component school- and family-based intervention for 4th graders and their families intended to promote positive food and activity environments, policies and behaviors at the individual, family and school levels. This paper describes the design and evaluation plan. Four cohorts of 4th-graders and their parents from 8 schools in 2 districts in the same Northern Colorado region are participating in a 4-arm cluster randomized controlled trial. Theory-based Fuel for Fun consists of 5 components delivered over 1 school year: 1) Cooking with Kids - Colorado; an experiential classroom-based cooking and tasting curriculum, 2) Cafeteria Connections; cafeteria-based reinforcements of classroom food experiences using behavioral economic strategies, 3) SPARK active recess; a playground intervention to engage children in moderate to vigorous activity, 4) Fuel for Fun Family; multi-element supports targeting parents to reinforce the 3 school-based components at home, and 5) About Eating; an online interactive program for parents addressing constructs of eating competence and food resource management. Outcomes include child and parent measures of fruit and vegetable preferences and intake, cooking, physical activity, sedentary behaviors and attitudes. School level data assess lunch plate waste and physical activity at recess. In-depth diet and accelerometry assessments are collected with a subsample of parent-child dyads. Data are collected at baseline, immediately post-intervention at 7 months, and at 12 month follow-up. We anticipate recruiting 1320-1584 children and their parents over the length of the project. The Fuel for Fun study design allows for impact assessment of school-, family- and online parent-based intervention components separately and in combination. Study strengths include use of theory- and evidence-based programs, valid child and parent self-report instruments, and objective measures of food, cooking, and physical activity behaviors at the individual, family and school levels. Parent involvement and engagement is examined through multiple strategies. Clinicaltrials.gov registration number NCT02491294 . Registered 7 July, 2015.

Stigma and violence in dealing with madness: narratives from psychosocial care centers in Bahia and Sergipe, Northeastern Brazil.

Nunes, Mônica; Torrenté, Maurice de

2009-08-01

To analyze stigmatization processes and types of violence experienced by individuals with mental disorders. A qualitative study was carried out, based on individual interviews with users and focus groups with family members and professionals at five psychosocial care centers in the municipalities of Itaberaba, Lauro de Freitas, Salvador, Vitória da Conquista, and Aracaju, Northeastern Brazil, in 2006-2007. The analysis categories were constructed based on the stigma concept proposed by Goffman, and four types of violence were systematized: interpersonal, institutional, symbolic and structural. Users and family members recounted examples of disqualification, reprimands, embarrassment, humiliation, negligence and physical aggression that had the aims of domination, exploitation and oppression. Professionals reported that people who suffer from mental disorders remain the target of prejudice that is culturally ingrained and naturalized. The main consequence is continuation of their isolation from social life as a form of 'treatment' or as an excluding attitude manifested by discriminatory reactions in the form of rejection, indifference and verbal or physical aggressiveness. The various ways of expressing stigma denote a sociocultural situation of violence against individuals with mental disorders. It is proposed that state monitoring bodies capable of planning and evaluating countermeasures against stigmatization should be set up.

INTEGRATION OF PANDA WORKLOAD MANAGEMENT SYSTEM WITH SUPERCOMPUTERS

DOE Office of Scientific and Technical Information (OSTI.GOV)

De, K; Jha, S; Maeno, T

Abstract The Large Hadron Collider (LHC), operating at the international CERN Laboratory in Geneva, Switzerland, is leading Big Data driven scientific explorations. Experiments at the LHC explore the funda- mental nature of matter and the basic forces that shape our universe, and were recently credited for the dis- covery of a Higgs boson. ATLAS, one of the largest collaborations ever assembled in the sciences, is at the forefront of research at the LHC. To address an unprecedented multi-petabyte data processing challenge, the ATLAS experiment is relying on a heterogeneous distributed computational infrastructure. The ATLAS experiment uses PanDA (Production and Datamore » Analysis) Workload Management System for managing the workflow for all data processing on over 140 data centers. Through PanDA, ATLAS physicists see a single computing facility that enables rapid scientific breakthroughs for the experiment, even though the data cen- ters are physically scattered all over the world. While PanDA currently uses more than 250000 cores with a peak performance of 0.3+ petaFLOPS, next LHC data taking runs will require more resources than Grid computing can possibly provide. To alleviate these challenges, LHC experiments are engaged in an ambitious program to expand the current computing model to include additional resources such as the opportunistic use of supercomputers. We will describe a project aimed at integration of PanDA WMS with supercomputers in United States, Europe and Russia (in particular with Titan supercomputer at Oak Ridge Leadership Com- puting Facility (OLCF), Supercomputer at the National Research Center Kurchatov Institute , IT4 in Ostrava, and others). The current approach utilizes a modified PanDA pilot framework for job submission to the supercomputers batch queues and local data management, with light-weight MPI wrappers to run single- threaded workloads in parallel on Titan s multi-core worker nodes. This implementation was tested with a variety of Monte-Carlo workloads on several supercomputing platforms. We will present our current accom- plishments in running PanDA WMS at supercomputers and demonstrate our ability to use PanDA as a portal independent of the computing facility s infrastructure for High Energy and Nuclear Physics, as well as other data-intensive science applications, such as bioinformatics and astro-particle physics.« less

To examine the associations between depressive/anxiety disorders (DAs), perceived health-related quality of life (HRQOL) and mortality in dialysis patients. Patients were assessed for depressive and DAs with the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders. The HRQOL was assessed with the Medical Outcome Short Form 36 (MOS SF-36), and the Beck Depression Inventory and Hospital Anxiety and Depression Scale were also applied. Sociodemographic, clinical and laboratory data were also collected. Patients with depressive disorders reported more impaired HRQOL on four of the eight subscales, while those with a depressive disorder comorbid with DA reported more impairment on all MOS SF-36 subscales compared to those without any psychiatric disorder. During the observation period, 50% of those with depression, 28% of those with anxiety and 33% of patients with DA disorder died. A survival analysis did not indicate that patients with depressive or DAs had a higher mortality than patients without such disorders. Dialysis patients with depressive disorders reported impaired HRQOL, whereas those with DAs did not. Patients with DA reported the most serious HRQOL impairment. No evidence was obtained to support the hypothesis that depressive and DAs contributed to compromised survival in dialysis patients. In patients with depression, DAs should also be assessed as they significantly contribute to impaired HRQOL. Copyright © 2013 Elsevier Inc. All rights reserved.

This paper presents the computational aeroelastic results generated in support of the second Aeroelastic Prediction Workshop for the Benchmark Supercritical Wing (BSCW) configurations and compares them to the experimental data. The computational results are obtained using FUN3D, an unstructured grid Reynolds- Averaged Navier-Stokes solver developed at NASA Langley Research Center. The analysis results include aerodynamic coefficients and surface pressures obtained for steady-state, static aeroelastic equilibrium, and unsteady flow due to a pitching wing or flutter prediction. Frequency response functions of the pressure coefficients with respect to the angular displacement are computed and compared with the experimental data. The effects of spatial and temporal convergence on the computational results are examined.

The Animal Fun program was designed to enhance the motor ability of young children by imitating the movements of animals in a fun, inclusive setting. The efficacy of this program was investigated through a randomized controlled trial using a multivariate nested cohort design. Pre-intervention scores were recorded for 511 children aged 4.83 years to 6.17 years (M=5.42 years, SD=3.58 months). Six control and six intervention schools were compared 6 months later following the intervention, and then again at 18 months after the initial testing when the children were in their first school year. Changes in motor performance were examined using the Bruininks-Oseretsky Test of Motor Proficiency short form. Data were analyzed using multi-level-mixed effects linear regression. A significant Condition×Time interaction was found, F(2,1219)=3.35, p=.035, demonstrating that only the intervention group showed an improvement in motor ability. A significant Sex×Time interaction was also found, F(2,1219)=3.84, p=.022, with boys improving over time, but not girls. These findings have important implications for the efficacy of early intervention of motor skills and understanding the differences in motor performance between boys and girls.

2016-01-01

The advances of omics technologies have triggered the production of an enormous volume of data coming from thousands of species. Meanwhile, joint international efforts like the Gene Ontology (GO) consortium have worked to provide functional information for a vast amount of proteins. With these data available, we have developed FunTaxIS, a tool that is the first attempt to infer functional taxonomy (i.e. how functions are distributed over taxa) combining functional and taxonomic information. FunTaxIS is able to define a taxon specific functional space by exploiting annotation frequencies in order to establish if a function can or cannot be used to annotate a certain species. The tool generates constraints between GO terms and taxa and then propagates these relations over the taxonomic tree and the GO graph. Since these constraints nearly cover the whole taxonomy, it is possible to obtain the mapping of a function over the taxonomy. FunTaxIS can be used to make functional comparative analyses among taxa, to detect improper associations between taxa and functions, and to discover how functional knowledge is either distributed or missing. A benchmark test set based on six different model species has been devised to get useful insights on the generated taxonomic rules. PMID:27534507

Aeroacoustic Simulations of a Nose Landing Gear with FUN3D: A Grid Refinement Study

2017-01-01

A systematic grid refinement study is presented for numerical simulations of a partially-dressed, cavity-closed (PDCC) nose landing gear configuration that was tested in the University of Florida's open-jet acoustic facility known as the UFAFF. The unstructured-grid flow solver FUN3D is used to compute the unsteady flow field for this configuration. Mixed-element grids generated using the Pointwise (Registered Trademark) grid generation software are used for numerical simulations. Particular care is taken to ensure quality cells and proper resolution in critical areas of interest in an effort to minimize errors introduced by numerical artifacts. A set of grids was generated in this manner to create a family of uniformly refined grids. The finest grid was then modified to coarsen the wall-normal spacing to create a grid suitable for the wall-function implementation in FUN3D code. A hybrid Reynolds-averaged Navier-Stokes/large eddy simulation (RANS/LES) turbulence modeling approach is used for these simulations. Time-averaged and instantaneous solutions obtained on these grids are compared with the measured data. These CFD solutions are used as input to a FfowcsWilliams-Hawkings (FW-H) noise propagation code to compute the farfield noise levels. The agreement of the computed results with the experimental data improves as the grid is refined.

CFL3D, FUN3d, and NSU3D Contributions to the Fifth Drag Prediction Workshop

2013-01-01

Results presented at the Fifth Drag Prediction Workshop using CFL3D, FUN3D, and NSU3D are described. These are calculations on the workshop provided grids and drag adapted grids. The NSU3D results have been updated to reflect an improvement to skin friction calculation on skewed grids. FUN3D results generated after the workshop are included for custom participant generated grids and a grid from a previous workshop. Uniform grid refinement at the design condition shows a tight grouping in calculated drag, where the variation in the pressure component of drag is larger than the skin friction component. At this design condition, A fine-grid drag value was predicted with a smaller drag adjoint adapted grid via tetrahedral adaption to a metric and mixed-element subdivision. The buffet study produced larger variation than the design case, which is attributed to large differences in the predicted side-of-body separation extent. Various modeling and discretization approaches had a strong impact on predicted side-of-body separation. This large wing root separation bubble was not observed in wind tunnel tests indicating that more work is necessary in modeling wing root juncture flows to predict experiments.

Aeroacoustic Simulation of Nose Landing Gear on Adaptive Unstructured Grids With FUN3D

NASA Technical Reports Server (NTRS)

Vatsa, Veer N.; Khorrami, Mehdi R.; Park, Michael A.; Lockard, David P.

2013-01-01

Numerical simulations have been performed for a partially-dressed, cavity-closed nose landing gear configuration that was tested in NASA Langley s closed-wall Basic Aerodynamic Research Tunnel (BART) and in the University of Florida's open-jet acoustic facility known as the UFAFF. The unstructured-grid flow solver FUN3D, developed at NASA Langley Research center, is used to compute the unsteady flow field for this configuration. Starting with a coarse grid, a series of successively finer grids were generated using the adaptive gridding methodology available in the FUN3D code. A hybrid Reynolds-averaged Navier-Stokes/large eddy simulation (RANS/LES) turbulence model is used for these computations. Time-averaged and instantaneous solutions obtained on these grids are compared with the measured data. In general, the correlation with the experimental data improves with grid refinement. A similar trend is observed for sound pressure levels obtained by using these CFD solutions as input to a FfowcsWilliams-Hawkings noise propagation code to compute the farfield noise levels. In general, the numerical solutions obtained on adapted grids compare well with the hand-tuned enriched fine grid solutions and experimental data. In addition, the grid adaption strategy discussed here simplifies the grid generation process, and results in improved computational efficiency of CFD simulations.

Care and support of children with physical or mental disabilities are accompanied with serious concerns for parents, families, healthcare institutions, schools, and their communities. Recent studies and technological innovations have demonstrated the feasibility of providing therapy and rehabilitation services to children supported by computer games. The aim of this paper is to present HapHop-Physio, an innovative computer game that combines exercise with fun and learning, developed to support cognitive therapies in children. Conventional software engineering methods such as the Scrum methodology, a functionality test and a related usability test, were part of the comprehensive methodology adapted to develop HapHop-Physio. The game supports visual and auditory attention therapies, as well as visual and auditory memory activities. The game was developed by a multidisciplinary team, which was based on the Hopscotch ® platform provided by Fraunhofer Institute for Digital Media Technology IDMT Institute in Germany, and designed in collaboration with a rehabilitation clinic in Colombia. HapHop-Physio was tested and evaluated to probe its functionality and user satisfaction. The results show the development of an easy-to-use and funny game by a multidisciplinary team using state-of-the-art videogame technologies and software methodologies. Children testing the game concluded that they would like to play again while undergoing rehabilitation therapies.

This study assesses chronic disease or disease-related conditions as motivators of physical activity. It also compares these and other motivators of physical activity between Senior Games participants (SGPs) and the general population. Analyses are based on an anonymous cross-sectional survey conducted among 666 SGPs and 177 individuals from the general population. SGPs experienced better general health and less obesity, diabetes, and depression, as well as an average of 14.7 more years of regular physical activity (p < .0001), 130.8 more minutes per week of aerobic activity (p < .0001), and 42.7 more minutes of anaerobic activity per week (p < .0001). Among those previously told they had diabetes, high blood pressure, high cholesterol, or depression, 74.2%, 72.2%, 70.4%, and 60.6%, respectively, said that it motivated them to increase their physical activity. Percentages were similar between SGPs and the general population. SGPs were more likely motivated to be physically active to improve physical and mental health in the present, to prevent physical and cognitive decline in the future, and to increase social opportunities. The Senior Games reinforces extrinsic motivators to positively influence intrinsic promoters such as skill development, satisfaction of learning, enjoyment, and fun. PMID:28138459

To this day, I can recite the Sara Sparrow definition of adaptive behavior. To this day, I recall Sara sitting on the other side of a one-way mirror observing me, an inexperienced clinical psychology intern, administer the Vineland Adaptive Behavior Scales to the mother of a child with learning disabilities. Talk about nervous-- the world’s expert on adaptive behavior held my very internship and career success in her hands! Even though I stumbled through it, Sara reassured me that I did great…all I needed was more practice. So, thousands of Vineland’s later, I was launched. Both my first and my latest publications in the disability field used assessment tools that I learned from Sara—primarily the Vineland, but also several cognitive tests. Beyond these tools, I cherish key insights from Sara that have stayed with me over the long haul. First and foremost, Sara taught me how to be a real psychologist, how to carefully observe and assess people with standardized tools and with my own eyes and ears. Second, she instilled a practical skill that I still am working on—always be on time even if others are late! Third, Sara imbued a sense of fun and adventure into our training and she continued to be a source of inspiration and fun in the years after I left Yale. For us data-driven types, the process of research and discovery is inherently fun—it is a total blast. Yet Sara modeled that fun and enjoyment need to come in other ways that are more balanced or well-rounded—that are, in a word, adaptive. It seems a fitting tribute to Sara to submit a paper that related her treasured Vineland Scales to how people with developmental disabilities have fun. Thank you, Sara. PMID:22484792

United role of radon decay products and nano-aerosols in radon dosimetry

NASA Astrophysics Data System (ADS)

Smerajec, M.; Vaupotič, J.

2012-04-01

The major part of human exposure to natural radiation originates from inhalation of radon (Rn) and radon short-lived decay products (RnDP: 218Po, 214Pb, 214Bi and 214Po). RnDP are formed as a result of α-transformation of radon. In the beginning they are positive ions which neutralize and form clusters with air molecules, and later partly attach to background aerosol particles in indoor air. Eventually, they appear as radioactive nano-aerosols with a bimodal size distribution in ranges of 1-10 nm (unattached RnDP) and of 200-800 nm (attached RnDP). When inhaled, they are deposited in the respiratory tract. Deposition is more efficient for smaller particles. Therefore, the fraction (fun) of the unattached RnDP, which appears to be influenced by the number concentration and size distribution of general (background) aerosols in the ambient air, has a crucial role in radon dosimetry. Radon, radon decay products and general aerosols have been monitored simultaneously in the kitchen of a typical rural house under real living conditions, also comprising four human activities generating particular matter: cooking and baking, as two typical activities in kitchen, and cigarette smoking and candle burning. In periods without any human activity, the total number concentration of general aerosol ranged from 1000 to 3000 cm-3,with the geometric mean of particle diameter in the range of 60-68 nm and with 0.1-1 % of particles smaller than 10 nm. Preparation of coffee changed the concentration to 193,000 cm-3, the geometric mean of diameter to 20 nm and fraction of particles smaller than 10 nm to 11 %. The respective changes were for baking cake: 503,000 cm-3, 17 nm and 19 %, for smoking:423,000 cm-3, 83 nm and 0.4 %, and forcandle burning: 945,000 cm-3, 8 nm and 85 %. While, as expected, a reduction of fun was observed during cooking, baking and smoking, when larger particles were emitted, fun did not increase during candle burning with mostly particles smaller than 10 nm produced. Because the processes of RnDP creation by radioactive transformation, their neutralization, clustering and association with aerosol particles need time, the response of fun on the changes in general aerosol is delayed in time and therefore fun response on the fast changes, such as those caused by short human activities, may be obscured and even not observed.

To evaluate the effect of Chinese phytotherapyto reduce stress levels, anxiety and improve quality of life. double-blind randomized controlled trial with 89 volunteers divided into three groups: control (no intervention), Placebo and Phytotherapy. The study was conducted in 2015 with healthy adults treated at the Integrated and Eastern Therapy Institute,in Sao Paulo, Brazil. Participants were evaluated at baseline and after three weeks with the Stress Symptoms List (SSL), Anxiety Inventory-Trait and State and SF12v2 for quality of life. Intervention groups received a placebo or Gan May Zao formula (GMDZ)flaskwith 50 ml. According to ANOVA, there were significant differences (p = 0.025) after treatment of stress (SSL2). And the difference was between control and Phytotherapy groups, according to the Tukey post hoc (p = 0.022). There were no differences in the levels of state-anxiety and physical and mental domains in the SF12v2. The GMDZ formula reduced stress levels, but more studies are needed with greater sample, with reassessment of dosage and a longer period of treatment to confirm and extend the results.

The adjoint-based design capability in FUN3D is extended to allow efficient gradient- based optimization and design of concepts with highly integrated aero-propulsive systems. A circumferential distortion calculation, along with the derivatives needed to perform adjoint-based design, have been implemented in FUN3D. This newly implemented distortion calculation can be used not only for design but also to drive the existing mesh adaptation process and reduce the error associated with the fan distortion calculation. The design capability is demonstrated by the shape optimization of an in-house aircraft concept equipped with an aft fuselage propulsor. The optimization objective is the minimization of flow distortion at the aerodynamic interface plane of this aft fuselage propulsor.

Obesity can affect the thorax, diaphragm, and alterations in respiratory function even if the lungs are within normality. The respiratory compliance is very reduced by the increase in fat mass. To evaluate the effect of the physical therapeutic respiratory exercises on the thoracoabdominal mobility of obese individuals in pre-bariatric surgery. Cross-sectional and descriptive study, which used the cirtometry (axillary, xiphoid and abdominal) to evaluate the mobility of 74 individuals, 27 men and 47 women, in pre-bariatric surgery, assisted by the team EMAD, after eight weeks of physiotherapy, following a protocol of exercises, reevaluating and compared the measures pre and post intervention. Had positive correlation abdominal mobility in the total volume of all participants (p=0.010) and also for all the measures in the measurement of residual volume in three levels (p=0.000). Comparing genders, in total volume, cirtometry abdominal greater for women (p=0.015) when compared to men and residual volume, significance for either men or women in all measurements (p=0.000). Obese patients that underwent the physiotherapeutic treatment during the preoperative period, had pré respiratory dynamics improved by the increase in the mobility of the chest cavity and by the improvement of respiratory conscience.

Polyclonal (PAb) and monoclonal (MAb) antibodies to CT2-epitope of the C-terminal fragment of serotonin transporter (SERT) protein were used to study the levels and molecular heterogeneity of platelet SERT in healthy donors and patients with affective (AD) and somatoform (SD) disorders, schizoaffective disorder (SAD) and schizophrenia. SERT was found to exist as high molecular wight (HMW) and low molecular weight (LMW) forms separated after electrophoresis. The levels of HMW and LMW forms of SERT were significantly, decreased in mentally ill patients as compared to healthy individuals. Unlike PAb, horse radish peroxidase (HRP)-conjugated MAbs were more sensitive and specific to SERT and could detect the LMW form of SERT as a duplet protein form with MW about 40 and 43 kDa. The MAb to CT2 C-terminal fragment of SERT conjugated with HRP is considered to be a new valuable tool for further investigation of SERT expression, properties, and posttranslation modification in the controls and in patients with different psychopathology.

The role of papillary muscle function in severe mitral regurgitation with preserved and reduced left ventricular ejection fraction and the method of choice to evaluate PM have still been the subjects of controversy. To evaluate and compare papillary muscle function in and between patients with severe degenerative and functional mitral regurgitation by using the free strain method. 64 patients with severe mitral regurgitation - 39 patients with degenerative mitral regurgitation (DMR group) and 25 patients with severe functional mitral regurgitation (FMR group) - and 30 control subjects (control group) were included in the study. Papillary muscle function was evaluated through the free strain method from apical four chamber images of the anterolateral papillary muscle (APM) and from apical three chamber images of the posteromedial papillary muscle (PPM). Global left ventricular longitudinal and circumferential strains were evaluated by applying 2D speckle tracking imaging. Global left ventricular longitudinal strain (DMR group, -17 [-14.2/-20]; FMR group, -9 [-7/-10.7]; control group, -20 [-18/-21] p < 0.001), global left ventricular circumferential strain (DMR group, -20 [-14.5/-22.7]; FMR group, -10 [-7/-12]; control group, -23 [-21/-27.5] p < 0.001) and papillary musle strains (PPMS; DMR group, -30.5 [-24/-46.7]; FMR group, -18 [-12/-30]; control group; -43 [-34.5/-39.5] p < 0.001; APMS; DMR group, (-35 [-23.5/-43]; FMR group, -20 [-13.5/-26]; control group, -40 [-32.5/-48] p < 0.001) were significantly different among all groups. APMS and PPMS were highly correlated with LVEF (p < 0.001, p < 0.001; respectively), GLS (p < 0.001, p < 0.001; respectively) and GCS (p < 0.001, p < 0.00; respectively) of LV among all groups. No correlation was found between papillary muscle strains and effective orifice area (EOA) in both groups of severe mitral regurgitation. Measuring papillary muscle longitudinal strain by the free strain method is practical and applicable. Papillary muscle dysfunction plays a small role in severe MR due to degenerative or functional causes and papillary muscle functions in general seems to follow left ventricular function. PPM is the most affected PM in severe mitral regurgitation in both groups of DMR and FMR. O papel da função do músculo papilar na regurgitação mitral grave com fração de ejeção do ventrículo esquerdo preservada e reduzida e o método de escolha para avaliar PM ainda são objetos de controvérsia. Avaliar e comparar a função dos músculos papilares entre pacientes com insuficiência mitral funcional e degenerativa pelo método free strain. 64 pacientes com insuficiência mitral grave - 39 pacientes com insuficiência mitral degenerativa grave (grupo IMD) e 25 com insuficiência mitral funcional grave (grupo IMF) - e 30 indivíduos controle (grupo controle) foram incluídos no estudo. A função dos músculos papilares foi avaliada pelo método free strain a partir de imagens apicais quatro-câmaras do músculo papilar anterolateral (MPA) e imagens apicais três-câmaras do músculo papilar posteromedial (MPP). Strains circunferenciais e longitudinais globais do ventrículo esquerdo foram avaliados por meio de imagens bidimensionais a partir do rastreamento de conjunto de pontos de cinza (speckle tracking). O strain longitudinal global do ventrículo esquerdo (grupo IMD, -17 [-14,2/-20]; grupo IMF, -9 [-7/-10,7]; grupo controle, -20 [-18/-21] p < 0,001); strain circunferencial global do ventrículo esquerdo (grupo IMD, -20 [-14,5/-22,7]; grupo IMF, -10 [-7/-12]; grupo controle, -23 [-21/-27,5] p < 0,001) e strains de músculos papilares (MPP; grupo IMD, -30,5 [-24/-46,7]; grupo IMF, -18 [-12/-30]; grupo controle; -43 [-34,5/-39,5] p < 0,001; MPA; grupo IMD, (-35 [-23,5/-43]; grupo IMF, -20 [-13,5/-26]; grupo controle, -40 [-32,5/-48] p < 0,001) mostraram-se significativamente diferentes nos grupos. MPA e MPP mostraram-se altamente correlacionados com a FEVE (p < 0,001, p < 0,00; respectivamente), SLG (p < 0,001, p < 0,001; respectivamente) e SCG (p < 0,001, p < 0,001; respectivamente) do VE entre todos os grupos. Não foi encontrada correlação entre os strains de músculos papilares e área eficaz do orifício (AEO) nos grupos de insuficiência mitral grave. A medição do strain longitudinal de músculos papilares pelo método free strain é prática e aplicável. A disfunção dos músculos papilares tem um papel pequeno em IM grave devido a causas degenerativas e funcionais, e a função dos músculos papilares, em general, parece seguir a função ventricular esquerda. O MPP é o MP mais afetado na insuficiência mitral em ambos os grupos, IMD e IMF.

The purpose of this study was to investigate physical activity levels across the five stages of change for physical activity and to identify motivational factors for physical activity according to these stages of change among college students in Amman, Jordan. Analyses were based on a cross-sectional survey of 431 students, with a mean age of 21.1 (SD=0.16) and 67.5% female. Based on the recommendation that physical activity requires at least 30 minutes of physical activity 3 or more days per week, men were more likely than women to classify themselves in later stages: 7.3% vs. 9.5% in the precontemplation stage, 17.4% vs. 14.7% in the contemplation stage, 50.0% vs. 63.5% in the preparation stage, 9.4% vs. 5.6% in the action stage, and 15.9% vs. 6.7% in the maintenance stage [X2(4) = 14.04, p = 0.0072]. Seven potential motivational items for physical activity were assessed using factor analysis: experience better self-worth, prevent chronic disease, relieve stress, stay in shape, longevity, recreation/fun, and social benefits. Two factor groupings were identified from these items. The first factor included the first five items, labeled as "Physical and Mental". The second factor included the last two items, labeled as "Social and Recreational." "Physical and Mental" items compared with "Social and Recreational" items were most likely to motivate physical activity across the stages of change for physical activity. The strongest motivator of physical activity was to stay in shape. The weakest motivator of physical activity was for social reasons. The influence of the intermediate motivational factors was slightly affected by the students' stage of change for physical activity. Motivators for physical activity did not differ according to sex. These results provide important information about the motivational factors for physical activity for college-aged students in Jordan that can be useful in developing effective physical activity intervention programs.

The field of neuroscience is generating increased public appetite for information about exciting brain research and discoveries. As stewards of the discipline, together with FUN and others, the Society for Neuroscience (SfN) embraces public outreach and education as essential to its mission of promoting understanding of the brain and nervous system. The Society looks to its members, particularly the younger generation of neuroscientists, to inspire, inform and engage citizens of all ages, and most importantly our youth, in this important endeavor. Here we review SfN programs and resources that support public outreach efforts to inform, educate and tell the story of neuroscience. We describe the important role the Brain Awareness campaign has played in achieving this goal and highlight opportunities for FUN members and students to contribute to this growing effort. We discuss specific programs that provide additional opportunities for neuroscientists to get involved with K-12 teachers and students in ways that inspire youth to pursue further studies and possible careers in science. We draw attention to SfN resources that support outreach to broader audiences. Through ongoing partnerships such as that between SfN and FUN, the neuroscience community is well positioned to pursue novel approaches and resources, including harnessing the power of the Internet. These efforts will increase science literacy among our citizens and garner more robust support for scientific research.

One hundred and thirty-three preclinical medical students participated in 24 focus groups over the period 2007-2009 at Durham University. Focus groups were conducted to ascertain whether or not medical students found body painting anatomical structures to be an educationally beneficial learning activity. Data were analyzed using a grounded theory approach. Five principal themes emerged: (1) body painting as a fun learning activity, (2) body painting promoting retention of knowledge, (3) factors contributing to the memorability of body painting, (4) removal from comfort zone, and (5) the impact of body painting on students' future clinical practice. Students perceive body painting to be a fun learning activity, which aids their retention of the anatomical knowledge acquired during the session. Sensory factors, such as visual stimuli, especially color, and the tactile nature of the activity, promote recall. Students' preference for painting a peer or being painted is often dependent upon their learning style, but there are educational benefits for both roles. The moderate amounts of undressing involved encouraging students to consider issues surrounding body image; this informs their attitudes towards future patients. Body painting is a useful adjunct to traditional anatomy and clinical skills teaching. The fun element involved in the delivery of this teaching defuses the often formal academic context, which in turn promotes a positive learning environment.

Depression is a highly prevalent and recurrent mental disorder that impacts all aspects of human life. Undesirable effects of the antidepressant drugs led to the development of complementary and alternative therapies. Gan-Mai-Da-Zao-Tang (, gān mài dà zǎo tang) is a traditional herbal formula commonly used for the treatment of depression, but lack of scientific proof on its mechanism. It consisted of Glycyrrhiza uralensis Fisch. (licorice), Triticum aestivum L. (wheat) and Zizphus jujuba Mill. (jujube). The objective of this study is to investigate the antidepressant effects of Gan-Mai-Dazao-Tang and its ingredients in rats exposed to forced swimming test (FST). The 72 of male Nerl: Wistar rats (8 weeks old) were randomized into control (10 mL/kg bw H 2 O), licorice (0.4 g/kg bw), wheat (1.6 g/kg bw), jujube (0.5 g/kg bw), Gan-Mai-Da-Zao-Tang (2.5 g/kg bw of licorice: wheat: jujube in ratio of 5:20:6) and Prozac (18 mg/kg bw) groups. Samples were administered by oral gavage for 21 days. FST was performed on 21st day, with 15 min for pretest followed by 5 min for real test. Then, the animals were sacrificed and brain tissues were collected for monoamines analyses. The Gan-Mai-Da-Zao-Tang (LWJ) showed significantly down-regulation of immobility time, 3,4-dihydroxyphenylacetic acid (DOPAC) and DOPAC/dopamine (DA) turnover rates, and also enhanced the concentration of serotonin (5-HT) and DA in brain tissues, as compared with the control. The LWJ stated the potent antidepressant-like effect by modulating these monoamines concentration, while the licorice, wheat and jujube did not reported significant results as compared with control group. The positive control (Prozac) was noted with significantly reduction in body weight and appetite. In conclusion, the antidepressant-like effects of LWJ might be mediated by the regulation of monoamine neurotransmitters. Thus, it could beneficial in depression treatment as a complementary approach.

Full seven-equation Reynolds stress turbulence models are promising tools for today’s aerospace technology challenges. This paper examines two such models for computing challenging turbulent flows including shock-wave boundary layer interactions, separation and mixing layers. The Wilcox and the SSG/LRR full second-moment Reynolds stress models have been implemented into the FUN3D (Fully Unstructured Navier-Stokes Three Dimensional) unstructured Navier-Stokes code and were evaluated for four problems: a transonic two-dimensional diffuser, a supersonic axisymmetric compression corner, a compressible planar shear layer, and a subsonic axisymmetric jet. Simulation results are compared with experimental data and results computed using the more commonly used Spalart-Allmaras (SA) one-equation and the Menter Shear Stress Transport (SST-V) two-equation turbulence models.

The Mg isotopic composition of major and minor mineral phases in the Allende inclusion C1 is reported. The results are analyzed in order to establish whether the Mg isotopic composition is the same in different phases and whether Al-26 is present in a sample which exhibited fractionation and unknown nuclear (FUN) effects on other elements. It is found that a small Mg-26 excess exists in C1 and is correlated with the Al-27/Mg-24 ratio, indicating that Al-26 was present in C1 together with the more general nuclear anomalies. The results also reveal that isotopic homogeneity of Mg in Mg-rich phases in C1 is evident in both bulk samples and single microscopic crystals.

Two forsterite-, fassaite-, spinel-rich inclusions in Allende which share common mineralogy and texture with three previously described inclusions are described. These inclusions were at least partially molten at temperatures over 1400 C, and their crystallization sequence was spinel, olivine, fassaite, and Mg-rich melilite. At least some of them experienced partial volatilization of MgO and SiO2 from their outer margins. At least one of the inclusions is highly enriched in MgO relative to CaO and Al2O3 compared to Allende coarse-grained inclusions, although it is just as strongly enriched in refractory trace elements as the latter, relative to C1 chondrites. Two of the objects are FUN inclusions on the basis of their oxygen, magnesium, and silicon isotopic compositions.

Games are by their nature interactive, informative and developmental and in many cases full of fun and entertainment. SAAO has used modern and indigenous games to communicate astronomy to learners, educators and members of the public. These games include board, card, stone, pen and paper, domino, singalongs, ball and computer games. The use of games serves to simplify, demystify and communicate hard concepts in a fun way. They extend beyond the confines of institutions as games can be played at home and school. There is also no need for supervision when rules are mastered. This presentation also examines the principles (racing, collection, simulation and placing) which underpin our games as well seeking to demonstrate how simple materials can be transformed into communication and educational tools by infusing relevant astronomical knowledge.

Boundary-layer stability analyses of mean flows extracted from unstructured-grid Navier- Stokes solutions have been performed. A procedure has been developed to extract mean flow profiles from the FUN3D unstructured-grid solutions. Extensive code-to-code validations have been performed by comparing the extracted mean ows as well as the corresponding stability characteristics to the predictions based on structured-grid solutions. Comparisons are made on a range of problems from a simple at plate to a full aircraft configuration-a modified Gulfstream-III with a natural laminar flow glove. The future aim of the project is to extend the adjoint-based design capability in FUN3D to include natural laminar flow and laminar flow control by integrating it with boundary-layer stability analysis codes, such as LASTRAC.

But making these products of pleasantry at times has not been as festive as it would seem. Sweetheart Cup Company has had its ups and downs in terms of many of the typical manufacturing measurements, but in 1994--under the direction of newly appointed Chief Operating Officer Bill McLaughlin--Sweetheart Cup Company embarked on a new mission. This time everyone would be involved, from headquarters staff in Owings Mills to the fourth-floor oven area workers in the Dallas bakery. The new process goal, "Business Excellence," as we called it, was really an implementation of Class A ERP/MRP II.

Light-element nucleosynthesis in a molecular cloud interacting with a supernova remnant and the origin of beryllium-10 in the protosolar nebula

The presence of short-lived radionuclides (t {sub 1/2} < 10 Myr) in the early solar system provides important information about the astrophysical environment in which the solar system formed. The discovery of now extinct {sup 10}Be (t {sub 1/2} = 1.4 Myr) in calcium-aluminum-rich inclusions (CAIs) with Fractionation and Unidentified Nuclear isotope anomalies (FUN-CAIs) suggests that a baseline concentration of {sup 10}Be in the early solar system was inherited from the protosolar molecular cloud. In this paper, we investigate various astrophysical contexts for the nonthermal nucleosynthesis of {sup 10}Be by cosmic-ray-induced reactions. We first show that the {sup 10}Be recordedmore » in FUN-CAIs cannot have been produced in situ by irradiation of the FUN-CAIs themselves. We then show that trapping of Galactic cosmic rays (GCRs) in the collapsing presolar cloud core induced a negligible {sup 10}Be contamination of the protosolar nebula, the inferred {sup 10}Be/{sup 9}Be ratio being at least 40 times lower than that recorded in FUN-CAIs ({sup 10}Be/{sup 9}Be ∼ 3 × 10{sup –4}). Irradiation of the presolar molecular cloud by background GCRs produced a steady-state {sup 10}Be/{sup 9}Be ratio ≲ 1.3 × 10{sup –4} at the time of the solar system formation, which suggests that the presolar cloud was irradiated by an additional source of CRs. Considering a detailed model for CR acceleration in a supernova remnant (SNR), we find that the {sup 10}Be abundance recorded in FUN-CAIs can be explained within two alternative scenarios: (1) the irradiation of a giant molecular cloud by CRs produced by ≳ 50 supernovae exploding in a superbubble of hot gas generated by a large star cluster of at least 20,000 members, and (2) the irradiation of the presolar molecular cloud by freshly accelerated CRs escaped from an isolated SNR at the end of the Sedov-Taylor phase. In the second picture, the SNR resulted from the explosion of a massive star that ran away from its parent OB association, expanded during most of its adiabatic phase in an intercloud medium of density of about 1 H-atom cm{sup –3}, and eventually interacted with the presolar molecular cloud only during the radiative stage. This model naturally provides an explanation for the injection of other short-lived radionuclides of stellar origin into the cold presolar molecular cloud ({sup 26}Al, {sup 41}Ca, and {sup 36}Cl) and is in agreement with the solar system originating from the collapse of a molecular cloud shocked by a supernova blast wave.« less

to estimate the healing rate of complex surgical wounds and its associated factors. retrospective cohort study from 2003 to 2014 with 160 outpatients of a Brazilian university hospital. Data were obtained through consultation of the medical records. Survival function was estimated using the Kaplan-Meier method and Cox regression model to estimate the likelihood of the occurrence of healing. the complex surgical wound healing rate was 67.8% (95% CI: 60.8-74.9). Factors associated with a higher likelihood of wound healing were segmentectomy/quadrantectomy surgery, consumption of more than 20 grams/day of alcohol, wound extent of less that 17.3 cm2 and the length of existence of the wound prior to outpatient treatment of less than 15 days, while the use of hydrocolloid covering and Marlex mesh were associated with a lower likelihood of healing. the wound healing rate was considered high and was associated with the type of surgical intervention, alcohol consumption, type of covering, extent and length of wound existence. Preventive measures can be implemented during the monitoring of the evolution of the complex surgical wound closure, with possibilities of intervention in the modifiable risk factors. estimar a taxa de cicatrização de ferida cirúrgica complexa e seus fatores associados. coorte retrospectiva de 2003 a 2014 com 160 pacientes ambulatoriais de um hospital universitário brasileiro.

Fragile X syndrome, caused by the loss of Fmr1 gene function, is the most common form of inherited mental retardation, with no effective treatment. Using a tractable animal model, we investigated mechanisms of action of a few FDA-approved psychoactive drugs that modestly benefit the cognitive performance in fragile X patients. Here we report that compounds activating serotonin (5HT) subtype 2B receptors (5HT2B-Rs) or dopamine (DA) subtype 1-like receptors (D1-Rs) and/or those inhibiting 5HT2A-Rs or D2-Rs moderately enhance Ras-PI3K/PKB signaling input, GluA1-dependent synaptic plasticity, and learning in Fmr1 knockout mice. Unexpectedly, combinations of these 5HT and DA compounds at low doses synergistically stimulate Ras-PI3K/PKB signal transduction and GluA1-dependent synaptic plasticity and remarkably restore normal learning in Fmr1 knockout mice without causing anxiety-related side effects. These findings suggest that properly dosed and combined FDA-approved psychoactive drugs may effectively treat the cognitive impairment associated with fragile X syndrome.

BAKCKGROUND: The first aim was to examine the effect of the UP4FUN pilot intervention on children's total sedentary time. The second aim was to investigate if the intervention had an effect on children's physical activity (PA) level. Finally, we aimed to investigate demographic differences (i.e. age, gender, ethnicity, living status and having siblings) between children in the intervention group who improved in sedentary time and PA at post-test and children in the intervention group who worsened in sedentary time and PA at post-test. The six weeks UP4FUN intervention was tested in a randomized controlled trial with pre-test post-test design with five intervention and five control schools in Belgium and included children of the 5th and 6th grade. The children wore accelerometers for seven days at pre- and post-test. Analyses included children with valid accelerometer data for at least two weekdays with minimum 10h-wearing time and one weekend day with 8h-wearing time. Final analyses included 372 children (60% girls, mean age = 10.9 ± 0.7 years). There were no significant differences in the change in sedentary time or light PA between intervention and control schools for the total sample or for the subgroup analyses by gender. However, children (specifically girls) in the intervention group had a higher decrease in moderate-to-vigorous PA than children in the control group. In the intervention group, children who lived with both parents and children with one or more siblings were less likely to reduce sedentary time after exposure to the intervention. Older children, girls and children who lived with both parents were less likely to increase light PA after the intervention. The UP4FUN intervention did not result in an effect on children's sedentary time. Based on the high amounts of accelerometer-derived sedentary time in this age group, more efforts are needed to develop strategies to reduce children's sedentary time.

Abnormal N-Glycosylation of a Novel Missense Creatine Transporter Mutant, G561R, Associated with Cerebral Creatine Deficiency Syndromes Alters Transporter Activity and Localization.

Cerebral creatine deficiency syndromes (CCDSs) are caused by loss-of-function mutations in creatine transporter (CRT, SLC6A8), which transports creatine at the blood-brain barrier and into neurons of the central nervous system (CNS). This results in low cerebral creatine levels, and patients exhibit mental retardation, poor language skills and epilepsy. We identified a novel human CRT gene missense mutation (c.1681 G>C, G561R) in Japanese CCDSs patients. The purpose of the present study was to evaluate the reduction of creatine transport in G561R-mutant CRT-expressing 293 cells, and to clarify the mechanism of its functional attenuation. G561R-mutant CRT exhibited greatly reduced creatine transport activity compared to wild-type CRT (WT-CRT) when expressed in 293 cells. Also, the mutant protein is localized mainly in intracellular membrane fraction, while WT-CRT is localized in plasma membrane. Western blot analysis revealed a 68 kDa band of WT-CRT protein in plasma membrane fraction, while G561R-mutant CRT protein predominantly showed bands at 55, 110 and 165 kDa in crude membrane fraction. The bands of both WT-CRT and G561R-mutant CRT were shifted to 50 kDa by N-glycosidase treatment. Our results suggest that the functional impairment of G561R-mutant CRT was probably caused by incomplete N-linked glycosylation due to misfolding during protein maturation, leading to oligomer formation and changes of cellular localization.

This survey is a preliminary step in a cooperative health-care programme, run by the association Le Pélican. It was conducted in July 1993 among the sampan dwellers in the district of Vi Da (Hué), Vietnam. The People's Committee of the town of Hué hopes to improve the living conditions of the inhabitants of the district. The work of the association is part of a wider project of integrated cooperation (Cités unies développement) for the community of sampan dwellers. The survey describes the demography, the state of children's health, the attitudes and behaviour of women and heads of the household towards maternity, contraception, disease and the health-care system. The Vi Da community is young: 40.5% of the inhabitants are under 15 years of age. The main health problems involve mothers and children: 56% of children aged between 5 and 59 months suffer from malnutrition; 71% of those between 0 and 15 years of age have never been vaccinated. The use of contraceptives is inadequate. Health-care services, however, are numerous and are mainly in the private sector. Any health-care project undertaken in this district to improve the state of children's health will have to reinforce the immunisation coverage and set up health education programmes dealing with nutrition and family planning. This will require a better knowledge of the mentality of the sampan dwellers, of their socio-cultural environment and their attitudes to illness and health-care.

Ventral striatal dysfunction in cocaine dependence - difference mapping for subregional resting state functional connectivity.

Zhang, Sheng; Li, Chiang-Shan R

2018-06-18

Research of dopaminergic deficits has focused on the ventral striatum (VS) with many studies elucidating altered resting state functional connectivity (rsFC) in individuals with cocaine dependence (CD). The VS comprises functional subregions and delineation of subregional changes in rsFC requires careful consideration of the differences between addicted and healthy populations. In the current study, we parcellated the VS using whole-brain rsFC differences between CD and non-drug-using controls (HC). Voxels with similar rsFC changes formed functional clusters. The results showed that the VS was divided into 3 subclusters, in the area of the dorsal-anterior VS (daVS), dorsal posterior VS (dpVS), and ventral VS (vVS), each in association with different patterns of rsFC. The three subregions shared reduced rsFC with bilateral hippocampal/parahippocampal gyri (HG/PHG) but also showed distinct changes, including reduced vVS rsFC with ventromedial prefrontal cortex (vmPFC) and increased daVS rsFC with visual cortex in CD as compared to HC. Across CD, daVS visual cortical connectivity was positively correlated with amount of prior-month cocaine use and cocaine craving, and vVS vmPFC connectivity was negatively correlated with the extent of depression and anxiety. These findings suggest a distinct pattern of altered VS subregional rsFC in cocaine dependence, and some of the changes have eluded analyses using the whole VS as a seed region. The findings may provide new insight to delineating VS circuit deficits in cocaine dependence and provide an alternative analytical framework to address functional dysconnectivity in other mental illnesses.

Research clearly documents the serious challenges and poor outcomes experienced by many young people exiting foster care, as well as compounded disparities for the high percentage of youth in care who are identified with disabilities and/or mental health challenges. However, very little research has been conducted to specify or validate effective models for improving the transition trajectories of youth exiting care. Evidence suggests the My Life self-determination enhancement model offers a promising approach for supporting youths' self-determined and positive transition to adulthood. The model includes youth-directed, experientially oriented coaching in the application of self-determination skills to achieve youth-identified transition goals, coupled with peer mentoring workshops that provide opportunities for learning, networking and fun. This in depth qualitative study of 10 youth who completed the My Life intervention focused on investigating coaching and mentoring elements and processes that youth participants identify as most important to their success, with the intention of informing the further development of youth-directed approaches to supporting young people who are transitioning to adulthood. Themes emerged around the centrality of youth self-direction, important processes in the coaching relationship, the essential value of experiential activities and self-determination skill development, and peer mentoring experiences that youth identified as fostering their success. Implications are discussed for research and practice in supporting youth exiting foster care.

Scientific blogging has become a more and more popular way of science outreach and communication. There are only a handful of soil science blogs, and I think there should be more! Blogging is a great way to share cool soil science stories, engage with the wider community, and promote understanding. It allows people to stumble over thoughts and ideas, and to think about how it fits in their daily life. It also provides an informal education and reference on the internet in a time where people Google everything. It can also be fun as well as being factual. At this talk, using my own experiences and the success of other soil science blogs, I will discuss: how to start a blog, why we should consider them as a way to communicate science, and what things to consider when you start your blog.

There are currently no studies available reporting intervention effects on breaking up children's sedentary time. This study examined the UP4FUN intervention effect on objectively measured number of breaks in sedentary time, number of sedentary bouts (≥ 10 mins) and total and average amount of time spent in those sedentary bouts among 10- to 12-year-old Belgian children. The total sample included 354 children (mean age: 10.9 ± 0.7 years; 59% girls) with valid ActiGraph accelerometer data at pre- and posttest. Only few and small intervention effects were found, namely on total time spent in sedentary bouts immediately after school hours (4-6PM; β = -3.51mins) and on average time spent in sedentary bouts before school hours (6-8.30AM; β = -4.83mins) and immediately after school hours in favor of children from intervention schools (β = -2.71mins). Unexpectedly, girls from intervention schools decreased the number of breaks during school hours (8.30AM-4PM; β = -23.45breaks) and increased the number of sedentary bouts on a weekend day (β = +0.90bouts), whereas girls in control schools showed an increase in number of breaks and a decrease in number of bouts. In conclusion, UP4FUN did not have a consistent or substantial effect on breaking up children's sedentary time and these data suggest that more intensive and longer lasting interventions are needed.

A Non-Cut Cell Immersed Boundary Method for Use in Icing Simulations

NASA Technical Reports Server (NTRS)

Sarofeen, Christian M.; Noack, Ralph W.; Kreeger, Richard E.

2013-01-01

This paper describes a computational fluid dynamic method used for modelling changes in aircraft geometry due to icing. While an aircraft undergoes icing, the accumulated ice results in a geometric alteration of the aerodynamic surfaces. In computational simulations for icing, it is necessary that the corresponding geometric change is taken into consideration. The method used, herein, for the representation of the geometric change due to icing is a non-cut cell Immersed Boundary Method (IBM). Computational cells that are in a body fitted grid of a clean aerodynamic geometry that are inside a predicted ice formation are identified. An IBM is then used to change these cells from being active computational cells to having properties of viscous solid bodies. This method has been implemented in the NASA developed node centered, finite volume computational fluid dynamics code, FUN3D. The presented capability is tested for two-dimensional airfoils including a clean airfoil, an iced airfoil, and an airfoil in harmonic pitching motion about its quarter chord. For these simulations velocity contours, pressure distributions, coefficients of lift, coefficients of drag, and coefficients of pitching moment about the airfoil's quarter chord are computed and used for comparison against experimental results, a higher order panel method code with viscous effects, XFOIL, and the results from FUN3D's original solution process. The results of the IBM simulations show that the accuracy of the IBM compares satisfactorily with the experimental results, XFOIL results, and the results from FUN3D's original solution process.

Exploring the role of positive and negative consequences in understanding perceptions and evaluations of individual drinking events

While research has established that drinking more alcohol is associated with experiencing more positive and negative alcohol-related consequences, less is known about how college students evaluate their drinking experiences. Evaluations of drinking events may vary with factors such as how much one drinks, which consequences one experiences, and the context (i.e., where and with whom) one drinks on a given occasion. This research used daily data (Level 2: N=166 students, 61% female; Level 1: N=848 person drinking days) to explore the relationship between quantity of alcohol consumed and experience of specific domains of positive and negative consequences and to examine how the experience of specific consequences related to overall evaluation of the drinking experience. Drinking on a given day was positively associated with experiencing more negative (social and personal) and more positive (image, fun/social, and relaxation) consequences. With respect to the formation of overall impressions, negative (social and personal) consequences were associated with less favorable evaluations whereas positive (image, fun/social, and relaxation) consequences were associated with more favorable evaluations of the drinking experience. Indirect effects analyses suggested that consequences (negative personal, negative social, positive fun/social, and positive relaxation) significantly mediated the relationship between drinking and overall evaluation at the daily level. These results underscore the importance of considering both positive and negative consequences in understanding students’ choices to drink and how they evaluate their experiences. PMID:20385445

In this study, using NextGen sequencing of the collective 16S rRNA genes obtained from two sets of samples collected from Lake Obersee, Antarctica, we compared and contrasted two bioinformatics tools, PICRUSt and Tax4Fun. We then developed an R script to assess the taxonomic and predictive functional profiles of the microbial communities within the samples. Taxa such as Pseudoxanthomonas, Planctomycetaceae, Cyanobacteria Subsection III, Nitrosomonadaceae, Leptothrix, and Rhodobacter were exclusively identified by Tax4Fun that uses SILVA database; whereas PICRUSt that uses Greengenes database uniquely identified Pirellulaceae, Gemmatimonadetes A1-B1, Pseudanabaena, Salinibacterium and Sinobacteraceae. Predictive functional profiling of the microbial communities using Tax4Fun and PICRUSt separately revealed common metabolic capabilities, while also showing specific functional IDs not shared between the two approaches. Combining these functional predictions using a customized R script revealed a more inclusive metabolic profile, such as hydrolases, oxidoreductases, transferases; enzymes involved in carbohydrate and amino acid metabolisms; and membrane transport proteins known for nutrient uptake from the surrounding environment. Our results present the first molecular-phylogenetic characterization and predictive functional profiles of the microbial mat communities in Lake Obersee, while demonstrating the efficacy of combining both the taxonomic assignment information and functional IDs using the R script created in this study for a more streamlined evaluation of predictive functional profiles of microbial communities.

Validation of a Node-Centered Wall Function Model for the Unstructured Flow Code FUN3D

NASA Technical Reports Server (NTRS)

Carlson, Jan-Renee; Vasta, Veer N.; White, Jeffery

2015-01-01

In this paper, the implementation of two wall function models in the Reynolds averaged Navier-Stokes (RANS) computational uid dynamics (CFD) code FUN3D is described. FUN3D is a node centered method for solving the three-dimensional Navier-Stokes equations on unstructured computational grids. The first wall function model, based on the work of Knopp et al., is used in conjunction with the one-equation turbulence model of Spalart-Allmaras. The second wall function model, also based on the work of Knopp, is used in conjunction with the two-equation k-! turbulence model of Menter. The wall function models compute the wall momentum and energy flux, which are used to weakly enforce the wall velocity and pressure flux boundary conditions in the mean flow momentum and energy equations. These wall conditions are implemented in an implicit form where the contribution of the wall function model to the Jacobian are also included. The boundary conditions of the turbulence transport equations are enforced explicitly (strongly) on all solid boundaries. The use of the wall function models is demonstrated on four test cases: a at plate boundary layer, a subsonic di user, a 2D airfoil, and a 3D semi-span wing. Where possible, different near-wall viscous spacing tactics are examined. Iterative residual convergence was obtained in most cases. Solution results are compared with theoretical and experimental data for several variations of grid spacing. In general, very good comparisons with data were achieved.

Suicide in elderly people: a literature review.

PubMed

Minayo, Maria Cecília de Souza; Cavalcante, Fátima Gonçalves

2010-08-01

A literature review was carried out focusing on the main factors associated with suicidal ideation, attempts and completed suicide in elders. The following databases were searched: MEDLINE, PsychINFO, SciELO and Biblioteca Virtual em Violência e Saúde da BIREME (BIREME's Violence and Health Virtual Library), referring to the period from 1980 to 2008. Fifty-two references were selected and analyzed. They showed a strong relationship among suicide ideation, attempt and completion in elderly individuals, which results from the interaction of complex physical, mental, neurobiological and social factors. Suicide associated with depression in the elderly can be prevented, provided the person is properly treated. In Brazil, it is necessary to invest in research, given the persistent increase in suicide rates among aged people, especially among males.

Physical activity promotion among underserved adolescents: "make it fun, easy, and popular".

PubMed

Louise Bush, Paula; Laberge, Suzanne; Laforest, Sophie

2010-05-01

There is a paucity of studies regarding noncurricular physical activity promotion interventions among adolescents, and even less such research pertaining to underserved youth. This article describes the development and implementation of a noncurricular, school-based physical activity promotion program designed for a multiethnic, underserved population of adolescents. The program's impact on leisure-time physical activity (LTPA) and on physical activity enjoyment (PAE) is also presented. The 16-week program, named FunAction, utilizes social marketing principles. Control (n = 90) and intervention (n = 131) students are assessed pre- and postintervention for levels of LTPA and PAE. Results indicate that although the program did not contribute to an increase in LTPA or PAE among intervention group students, participation in the program was elevated. This study offers preliminary evidence that noncurricular physical activity promotion programs that apply social marketing principles can be effective in engaging multiethnic, underserved adolescents in physical activity.

Disorientating, fun or meaningful? Disadvantaged families' experiences of a science museum visit

NASA Astrophysics Data System (ADS)

Archer, Louise; Dawson, Emily; Seakins, Amy; Wong, Billy

2016-12-01

It is widely agreed that there is a need to increase and widen science participation. Informal science learning environments (ISLEs), such as science museums, may provide valuable spaces within which to engage visitors—yet the visitor profile of science museums remains narrow. This paper seeks to understand the experiences of socially disadvantaged families within such spaces. Using a Bourdieusian analytic lens, we analyse qualitative data from a small study conducted with ten parents and ten children from an urban school who visited a large science museum. Data includes pre- and post-interviews, audio recordings and visit fieldnotes. We characterised families' experiences as falling into three discourses, as `disorientating', `fun' or `meaningful' visits. Analysis identifies how the families' experiences, and the likelihood of deriving science learning from the visit, were shaped through interactions of habitus and capital. Implications for improving equity and inclusion within ISLEs are discussed.

Time crawls when you're not having fun: feeling entitled makes dull tasks drag on.

PubMed

O'Brien, Edward H; Anastasio, Phyllis A; Bushman, Brad J

2011-10-01

All people have to complete dull tasks, but individuals who feel entitled may be more inclined to perceive them as a waste of their "precious" time, resulting in the perception that time drags. This hypothesis was confirmed in three studies. In Study 1, participants with higher trait entitlement (controlling for related variables) thought dull tasks took longer to complete; no link was found for fun tasks. In Study 2, participants exposed to entitled messages thought taking a dull survey was a greater waste of time and took longer to complete. In Study 3, participants subliminally exposed to entitled words thought dull tasks were less interesting, thought they took longer to complete, and walked away faster when leaving the laboratory. Like most resources, time is a resource valued more by entitled individuals. A time-entitlement link provides novel insight into mechanisms underlying self-focus and prosocial dynamics.

Physical and psychosocial function in residential aged-care elders: effect of Nintendo Wii Sports games.

PubMed

Keogh, Justin W L; Power, Nicola; Wooller, Leslie; Lucas, Patricia; Whatman, Chris

2014-04-01

This mixed-methods, quasi-experimental pilot study examined whether the Nintendo Wii Sports (NWS) active video game (exergame) system could significantly improve the functional ability, physical activity levels, and quality of life of 34 older adults (4 men and 30 women, 83 ± 8 yr) living in 2 residential aged-care (RAC) centers. Change score analyses indicated the intervention group had significantly greater increases in bicep curl muscular endurance, physical activity levels, and psychological quality of life than the control group (p < .05). Analysis of the quotes underlying the 3 themes (feeling silly, feeling good; having fun; and something to look forward to) suggested that intervention group participants developed a sense of empowerment and achievement after some initial reluctance and anxiousness. They felt that the games were fun and provided an avenue for greater socialization. These results add some further support to the utilization of NWS exergames in the RAC context.

Efficacy of propidium iodide and FUN-1 stains for assessing viability in basidiospores of Rhizopogon roseolus.

PubMed

Fernández-Miranda, Elena; Majada, Juan; Casares, Abelardo

2017-01-01

The use of spores in applications of ectomycorrhizal fungi requires information regarding spore viability and germination, especially in genera such as Rhizopogon with high rates of spore dormancy. The authors developed a protocol to assess spore viability of Rhizopogon roseolus using four vital stains to quantify spore viability and germination and to optimize storage procedures. They showed that propidium iodide is an excellent stain for quantifying nonviable spores. Observing red fluorescent intravacuolar structures following staining with 2-chloro-4-(2,3-dihydro-3-methyl-(benzo-1,3-thiazol-2-yl)-methylidene)-1-phenylquinolinium iodide (FUN-1) can help identify viable spores that are activated. At 6 mo and 1 y, the spores kept in a water suspension survived better than those left within intact, dry gasterocarps. Our work highlights the importance of temperature, nutrients, and vitamins for maturation and germination of spores of R. roseolus during 1 y of storage.

Fun Science: The Use of Variable Manipulation to Avoid Content Instruction

NASA Astrophysics Data System (ADS)

Peters-Burton, Erin E.; Hiller, Suzanne E.

2013-02-01

This study examined the beliefs and rationale pre-service elementary teachers used to choose activities for upper-elementary students in a 1-week intensive science camp. Six undergraduate elementary pre-service teachers were observed as they took a semester-long science methods class that culminated in a 1-week science camp. This qualitative, phenomenological study found that counselors chose activities with the possibility of fun being a priority rather than teaching content, even after they were confronted with campers who demanded more content. Additionally, all six of the counselors agreed that activities involving variable manipulation were the most successful, even though content knowledge was not required to complete the activities. The counselors felt the variable manipulation activities were successful because students were constructing products and therefore getting to the end of the activity. Implications include building an awareness of the complexity of self-efficacy of science teaching and outcome expectancy to improve teacher education programs.

Stabilized Finite Elements in FUN3D

NASA Technical Reports Server (NTRS)

Anderson, W. Kyle; Newman, James C.; Karman, Steve L.

2017-01-01

A Streamlined Upwind Petrov-Galerkin (SUPG) stabilized finite-element discretization has been implemented as a library into the FUN3D unstructured-grid flow solver. Motivation for the selection of this methodology is given, details of the implementation are provided, and the discretization for the interior scheme is verified for linear and quadratic elements by using the method of manufactured solutions. A methodology is also described for capturing shocks, and simulation results are compared to the finite-volume formulation that is currently the primary method employed for routine engineering applications. The finite-element methodology is demonstrated to be more accurate than the finite-volume technology, particularly on tetrahedral meshes where the solutions obtained using the finite-volume scheme can suffer from adverse effects caused by bias in the grid. Although no effort has been made to date to optimize computational efficiency, the finite-element scheme is competitive with the finite-volume scheme in terms of computer time to reach convergence.

Play with online virtual pets as a method to improve mirror neuron and real world functioning in autistic children.

PubMed

Altschuler, Eric Lewin

2008-01-01

Autism is a severe disease with no known cause and no cure or treatment. Recently, ourselves and subsequently others found that so-called "mirror neurons" - neurons that respond not only when a person moves, but upon observation of movement in another - are dysfunctional in autistic children. Here I suggest an easy, simple, inexpensive and fun method to improve mirror neuron functioning in autistic children, increase appreciation in autistic children for the theory of mind and thinking of others, and most importantly hopefully to improve real world functioning: play with virtual online pets that are the "embodiment" of a stuffed animal the child has. Adoption and then care and play with online pets forces, in a fun way, one to think about the world through the eyes and needs of the pet. A simple method to test this play with online virtual pet therapy is described.

Understanding the Magic of the Bicycle; Basic scientific explanations to the two-wheeler's mysterious and fascinating behavior

NASA Astrophysics Data System (ADS)

Connolly, Joseph W.

The bicycle is a common, yet unique mechanical contraption in our world. In spite of this, the bike's physical and mechanical principles are understood by a select few. You do not have to be a genius to join this small group of people who understand the physics of cycling. This is your guide to fundamental principles (such as Newton's laws) and the book provides intuitive, basic explanations for the bicycle's behaviour. Each concept is introduced and illustrated with simple, everyday examples. Although cycling is viewed by most as a fun activity, and almost everyone acquires the basic skills at a young age, few understand the laws of nature that give magic to the ride. This is a closer look at some of these fun, exhilarating, and magical aspects of cycling. In the reading, you will also understand other physical principles such as motion, force, energy, power, heat, and temperature.

Inflow/Outflow Boundary Conditions with Application to FUN3D

NASA Technical Reports Server (NTRS)

Carlson, Jan-Renee

2011-01-01

Several boundary conditions that allow subsonic and supersonic flow into and out of the computational domain are discussed. These boundary conditions are demonstrated in the FUN3D computational fluid dynamics (CFD) code which solves the three-dimensional Navier-Stokes equations on unstructured computational meshes. The boundary conditions are enforced through determination of the flux contribution at the boundary to the solution residual. The boundary conditions are implemented in an implicit form where the Jacobian contribution of the boundary condition is included and is exact. All of the flows are governed by the calorically perfect gas thermodynamic equations. Three problems are used to assess these boundary conditions. Solution residual convergence to machine zero precision occurred for all cases. The converged solution boundary state is compared with the requested boundary state for several levels of mesh densities. The boundary values converged to the requested boundary condition with approximately second-order accuracy for all of the cases.

Uso de modelos mecânicos em curso informal de astronomia para deficientes visuais. Resgate de uma experiência

NASA Astrophysics Data System (ADS)

Tavares, E. T., Jr.; Klafke, J. C.

2003-08-01

O presente trabalho propõe-se a resgatar uma experiência que teve lugar no Planetário de São Paulo nos anos 60. Em 1962, o Sr. Acácio, então com 37 anos, deficiente visual desde os 27, passou a assistir às aulas ministradas pelo Prof. Aristóteles Orsini aos integrantes do corpo de servidores do Planetário. O Sr. Acácio era o único deficiente da turma e, embora possuísse conhecimentos básicos e relativamente avançados de matemática, enfrentava dificuldades na compreensão e acompanhamento da exposição, como também em estudos posteriores. Com o intuito de auxiliá-lo na superação desses problemas, o Prof. Orsini solicitou a construção de modelos mecânicos que, através do sentido do tato, permitissem o acompanhamento das aulas e a transposição do modelo para o "constructo" mental. Essa prática mostrou-se tão eficaz que facilitou sobejamente o aprendizado da matéria pelo sujeito. O Sr. Acácio passou a integrar o corpo de professores do Planetário/Escola Municipal de Astrofísica, tendo ficado responsável pelo curso de "Introdução à Astronomia" por vários anos. Além disso, a experiência foi tão bem sucedida que alguns dos modelos tiveram seus elementos constitutivos pintados diferencialmente para serem utilizados em cursos regulares do Planetário, tornando-se parte integrante do conjunto de recursos didáticos da instituição. É pensando nessa eficácia, tanto em seu objetivo original permitir o aprendizado de um deficiente visual quanto no subsidiário recurso didático sistemático da instituição que decidimos resgatar essa experiência. Estribados nela, acreditamos ser extremamente produtivo, em termos educacionais, o aperfeiçoamento dos modelos originais, agora resgatados e restaurados, e a criação de outros que pudessem ser utilizados no ensino dessa ciência a deficientes visuais.

Due to the high failure rate observed in the clinical treatment of morbid obesity an increase in bariatric surgery indications, as an alternative for the control of obesity and comorbidities, is noticeable. To evaluate the performance of type 2 diabetes mellitus, high blood pressure and dyslipidemia in patients submitted to Roux-en-Y gastric bypass in late follow-up. Retrospective analysis of 59 patients included in the bariatric surgery program. Anthropometric (height and body weight) and laboratory (LDLc, HDLc, VLDLc, triglyceride -TG - and glucose) data were collected on pre- and postoperative stages, through medical records. Among the patients, 86% were female aged 43±11, of whom 52% had attended high school. The average postoperative time was 7±3 years. During the postoperative period, there were decreases of weight and body mass index, respectively (133±06 kg vs 91±04 kg p<0.05 e 49±74 kg/m2 vs 33±79 kg/m2, p<0.05). In comparison to the preoperative stage, lower concentrations of glucose (101.00±26.99 vs 89,11±15.19, p=0.014), total cholesterol rates (179.00±37,95 vs 167.48±28,50, p=0.016), LDLc (104.30±33.12 vs 91.46±24.58, p=0.016), VLDLc (25.40±11,12 vs 15.68±7.40, p<0.01), and TG (143.35±86.35 vs 82.45±37.39, p<0.01) and higher concentrations of HDLc (43.53±8.23 vs 57.90±15.60, p<0.01) were identified in the postoperative stage. 40% of hypertensive patients were still undergoing high blood pressure treatment during the postoperative stage. There was remission of type 2 diabetes mellitus and dyslipidemia on 81% and 94% of the cases, respectively. Roux-en-Y gastric bypass has proven itself to be an effective long term procedure, promoting weight loss, remission of DM2 and dyslipidemia. Em função do alto grau de falência que se observa no tratamento clínico da obesidade mórbida, observa-se um aumento da procura pela cirurgia bariátrica como alternativa para o controle da obesidade e comorbidades.

Análise retrospectiva de 59 pacientes inseridos em programa de cirurgia bariátrica. Foram coletados dados antropométricos (altura e peso corporal) e laboratoriais (LDLc, HDLc, VLDLc, triglicerídeo -TG - e glicose) nos períodos pré e pós-operatório por meio de prontuários médicos. Entre os pacientes, 86% eram mulheres com idade de 43±11 anos e 52% tinham cursado o ensino médio. O tempo médio de pós-operatório foi de 7±3 anos. Houve redução no peso e no índice de massa corporal no pós-operatório, respectivamente (133±06 kg vs 91±04 kg p<0,05 e 49±74 kg/m2 vs 33±79 kg/m2, p<0,05). Observou-se concentrações inferiores no pós-operatório, comparado com o pré-operatório, da glicose (101,00±26,99 vs 89,11±15,19, p=0,014), colesterol total (179,00±37,95 vs 167,48±28,50, p=0,016), LDLc (104,30±33,12 vs 91,46±24,58, p=0,016), VLDLc (25,40±11,12 vs 15,68±7,40, p<0,01), e TG (143,35±86,35 vs 82,45±37,39, p<0,01) e maiores de HDLc (43,53±8,23 vs 57,90±15,60, p<0,01 ). No pós-operatório 40% dos pacientes hipertensos ainda estavam em tratamento para hipertensão arterial sistêmica. Houve remissão do diabete melito tipo 2 e da dislipidemia em 81% e 94% dos casos, respectivamente. A gastroplastia redutora em Y-de-Roux mostrou ser procedimento eficaz em longo prazo, com resultados persistentes na perda de peso, remissão do DM2 e da dislipidemia.

This article highlights some of the critical issues that were discussed during a breakout session on career transitions at the 2014 Faculty for Undergraduate Neuroscience (FUN) Workshop at Ithaca College on Undergraduate Neuroscience Education: Challenges and Solutions in Creating and Sustaining Programs. Topics included: (1) transitioning from graduate school or a postdoc position to an assistant professor position; (2) preparing for promotion and tenure decisions; (3) balancing teaching, research, and service during a career in academics; (4) exploring alternative career options, including moving to another institution, taking on an administrative position, and working in industry; and (5) deciding when and how to retire. Much of the discussion focused on special challenges that women and minorities face in the academic environment. Participants offered valuable insights and suggestions for helping new faculty members prepare for reappointment, promotion, and tenure decisions, including utilizing networking connections within FUN for letters of support and collaborative opportunities. These networking opportunities were also valued by participants who were in rather unique positions, such as transitioning from a purely administrative role back to a regular faculty position or handling the extra burden of being a chair or program director with essentially the same research and grant-writing expectations of a regular faculty member. The session proved to be enlightening for most participants and though several questions and concerns remained unanswered, several ideas and insights were shared by the participants and a sense of empathy for the unique circumstances many of the participants were experiencing provided an atmosphere of comradery and support that often emanates from these FUN workshop sessions.

Integration of nitrogen dynamics into the Noah-MP land surface model v1.1 for climate and environmental predictions

Climate and terrestrial biosphere models consider nitrogen an important factor in limiting plant carbon uptake, while operational environmental models view nitrogen as the leading pollutant causing eutrophication in water bodies. The community Noah land surface model with multi-parameterization options (Noah-MP) is unique in that it is the next-generation land surface model for the Weather Research and Forecasting meteorological model and for the operational weather/climate models in the National Centers for Environmental Prediction. In this study, we add a capability to Noah-MP to simulate nitrogen dynamics by coupling the Fixation and Uptake of Nitrogen (FUN) plant model and the Soil and Water Assessment Tool (SWAT) soil nitrogen dynamics. This model development incorporates FUN's state-of-the-art concept of carbon cost theory and SWAT's strength in representing the impacts of agricultural management on the nitrogen cycle. Parameterizations for direct root and mycorrhizal-associated nitrogen uptake, leaf retranslocation, and symbiotic biological nitrogen fixation are employed from FUN, while parameterizations for nitrogen mineralization, nitrification, immobilization, volatilization, atmospheric deposition, and leaching are based on SWAT. The coupled model is then evaluated at the Kellogg Biological Station - a Long Term Ecological Research site within the US Corn Belt. Results show that the model performs well in capturing the major nitrogen state/flux variables (e.g., soil nitrate and nitrate leaching). Furthermore, the addition of nitrogen dynamics improves the modeling of net primary productivity and evapotranspiration. The model improvement is expected to advance the capability of Noah-MP to simultaneously predict weather and water quality in fully coupled Earth system models.

Having now worked in soil science and climate change for over 20 years, I find myself giving one of the "old man / old woman" lectures at the EGU2017. You probably get picked to do this when your peers think that you are about to die soon, so I had better make the most of my time left! We are very fortunate to have a career in science, and to belong to the soils, and the wider, biogeosciences communities. If ever you get fed up with your teaching load, with your experiment that won't work, your model that you can't get running, or your paper that reviewers do not realise for the gem that you know it is, remember that we could be doing a 9 to 5 job, stuck in an office, with no opportunities to meet, talk and have fun with others from around the world with whom we share the same passion. I hope you enjoy your research careers and the time you spend with your work friends as much as I have. In this presentation I will reflect on how much I have learned about soils, climate, and the politics of how things get done over the past 20 years, and I will pick out some changes in our understanding of soils, and their role in the world as I go. I will draw on examples not only from my own work, but those of others, and will reflect on the some of the fun I have had while doing this "job".

Perceptions of using videogames in rehabilitation: a dual perspective of people with multiple sclerosis and physiotherapists

Purpose: Our aim was to describe experiences of using Nintendo Wii Fit™ for balance exercise, from the perspectives of patients with multiple sclerosis (MS) and their physiotherapists (PT). Methods: Individual interviews with 15 patients with MS were conducted, recruited from a multi-centre study investigating the effects of balance exercising using Wii Fit. We also conducted a single focus group interview with nine PT involved in the study. The interviews were audio-recorded, transcribed, and analysed using content analysis. Results: Both patients and PT said that exercising with Wii Fit games was fun, and that it challenged the patients' physical and cognitive capacities. The competitive content in the games provided motivation to continue playing. Patients and PT reported improved body control and, more importantly, positive effects on balance and walking in daily life. The PT regarded Wii training as an effective alternative to other balance training, but some felt unsure in how to manage the video game. The patients regarded Wii training as a possible home training solution. Conclusions: Patients with MS and their PT considered Wii Fit exercises to be fun, challenging, and self-motivating. Exercising with Wii games can address balance impairments in MS, and can be performed at home as well as in rehabilitation settings. Implications for Rehabilitation Nintendo Wii Fit™ can be used as a fun and challenging way to perform balance exercises. The competitive content embedded in the games triggers continued playing and exercising. The positive effect on balance control can improve standing and walking in everyday activities. PMID:24833535

During the past decade, big data have become a major tool in scientific endeavors. Although statistical methods and algorithms are well-suited for analyzing and summarizing enormous amounts of data, the results do not allow for a visual inspection of the entire data. Current scientific software, including R packages and Python libraries such as ggplot2, matplotlib and plot.ly, do not support interactive visualizations of datasets exceeding 100 000 data points on the web. Other solutions enable the web-based visualization of big data only through data reduction or statistical representations. However, recent hardware developments, especially advancements in graphical processing units, allow for the rendering of millions of data points on a wide range of consumer hardware such as laptops, tablets and mobile phones. Similar to the challenges and opportunities brought to virtually every scientific field by big data, both the visualization of and interaction with copious amounts of data are both demanding and hold great promise. Here we present FUn, a framework consisting of a client (Faerun) and server (Underdark) module, facilitating the creation of web-based, interactive 3D visualizations of large datasets, enabling record level visual inspection. We also introduce a reference implementation providing access to SureChEMBL, a database containing patent information on more than 17 million chemical compounds. The source code and the most recent builds of Faerun and Underdark, Lore.js and the data preprocessing toolchain used in the reference implementation, are available on the project website (http://doc.gdb.tools/fun/). daniel.probst@dcb.unibe.ch or jean-louis.reymond@dcb.unibe.ch.

To evaluate the impact of a multi-component school-based physical activity intervention (Fit-4-Fun) on health-related fitness and objectively measured physical activity in primary school children. Four Hunter primary schools were recruited in April, 2011 and randomized by school into treatment or control conditions. Participants included 213 children (mean age = 10.72 years ± 0.6; 52.2% female) with the treatment group (n = 118) completing the 8-week Fit-4-Fun Program. Participants were assessed at baseline and 6-month follow-up, with a 91% retention rate. Cardio-respiratory fitness (CRF) (20 m shuttle run) was the primary outcome, and secondary outcomes included body composition (BMI, BMI(Z)), muscular fitness (7-stage sit-up test, push-up test, basketball throw test, Standing Jump), flexibility (sit and reach) and physical activity (7 days pedometry). After 6-months, significant treatment effects were found for CRF (adjusted mean difference, 1.14 levels, p < 0.001), body composition (BMI mean, -0.96 kg/m(2), p < 0.001 and BMI z-score mean -0.47 z-scores, p < 0.001), flexibility (sit and reach mean, 1.52 cm, p = 0.0013), muscular fitness (sit-ups) (mean 0.62 stages, p = 0.003) and physical activity (mean, 3253 steps/day, p < 0.001). There were no group by time effects for the other muscular fitness measures. A primary school-based intervention focusing on fitness education significantly improved health-related fitness and physical activity levels in children. Copyright © 2012 Elsevier Inc.

As a main staple food, rice is also a model plant for functional genomic studies of monocots. Decoding of every DNA element of the rice genome is essential for genetic improvement to address increasing food demands. The past 15 years have witnessed extraordinary advances in rice functional genomics. Systematic characterization and proper deposition of every rice gene are vital for both functional studies and crop genetic improvement. We built a comprehensive and accurate dataset of ∼2800 functionally characterized rice genes and ∼5000 members of different gene families by integrating data from available databases and reviewing every publication on rice functional genomic studies. The dataset accounts for 19.2% of the 39 045 annotated protein-coding rice genes, which provides the most exhaustive archive for investigating the functions of rice genes. We also constructed 214 gene interaction networks based on 1841 connections between 1310 genes. The largest network with 762 genes indicated that pleiotropic genes linked different biological pathways. Increasing degree of conservation of the flowering pathway was observed among more closely related plants, implying substantial value of rice genes for future dissection of flowering regulation in other crops. All data are deposited in the funRiceGenes database (https://funricegenes.github.io/). Functionality for advanced search and continuous updating of the database are provided by a Shiny application (http://funricegenes.ncpgr.cn/). The funRiceGenes dataset would enable further exploring of the crosslink between gene functions and natural variations in rice, which can also facilitate breeding design to improve target agronomic traits of rice. © The Authors 2017.

Few studies have examined the mediators of behavior change in successful school-based physical activity interventions. The aim of this study was to explore potential mediators of physical activity in the Fit-4-Fun program for primary school children. Group randomized controlled trial. Four primary schools were recruited in April, 2011 and randomized by school into intervention or control conditions. Participants included 213 children (mean age = 10.7 years ± 0.6; 52.2% female) with the treatment group (n = 118) completing the 8-week multi-component Fit-4-Fun program. Participants were assessed at baseline, 3- and 6-months. Physical activity was measured using Yamax SW700 pedometers (mean steps/day) and questionnaires were used to assess constructs from Social Cognitive Theory and Competence Motivation Theory. Hypothesized mediators measured included social support from peers, parents and teachers; physical activity self-efficacy (barrier and task); enjoyment; and perceived school physical environment. Mediation was assessed using Preacher and Hayes' multiple mediation regression SPSS macro. Action theory (A), conceptual theory (B) and the significance of the product of coefficients (AB) are reported. The intervention had a significant effect on physical activity (p<0.001). The action theory test results revealed significant treatment effects at 3-months for perceived school environment (A=0.28, p<0.001); and at 6-month follow-up for perceived school environment (A=0.058, p<0.001), teacher social support (A=0.54, p<0.05) and enjoyment (A=-0.23, p<0.05). The conceptual theory test revealed a significant relationship between changes in teacher social support and changes in physical activity at 6-month follow-up (B=828, P<0.05). Teacher social support was shown to have a significant mediating effect on physical activity (AB = 445, CI = 77-1068 steps, proportion= 13%), and perceived school environment approached significance (AB = 434, CI= -415 to 1507 steps, proportion= 13%). The Fit-4-Fun program successfully targeted social support for physical activity provided by classroom teachers which contributed to improved physical activity in children. These results demonstrate that classroom teachers play a key role in influencing physical activity behavior outcomes in children.Trial Registration No: ACTRN12611000976987.

A web-based computer-tailored smoking prevention programme for primary school children: intervention design and study protocol

PubMed Central

2012-01-01

Background Although the number of smokers has declined in the last decade, smoking is still a major health problem among youngsters and adolescents. For this reason, there is a need for effective smoking prevention programmes targeting primary school children. A web-based computer-tailored feedback programme may be an effective intervention to stimulate youngsters not to start smoking, and increase their knowledge about the adverse effects of smoking and their attitudes and self-efficacy regarding non-smoking. Methods & design This paper describes the development and evaluation protocol of a web-based out-of-school smoking prevention programme for primary school children (age 10-13 years) entitled ‘Fun without Smokes’. It is a transformation of a postal mailed intervention to a web-based intervention. Besides this transformation the effects of prompts will be examined. This web-based intervention will be evaluated in a 2-year cluster randomised controlled trial (c-RCT) with three study arms. An intervention and intervention + prompt condition will be evaluated for effects on smoking behaviour, compared with a no information control condition. Information about pupils’ smoking status and other factors related to smoking will be obtained using a web-based questionnaire. After completing the questionnaire pupils in both intervention conditions will receive three computer-tailored feedback letters in their personal e-mail box. Attitudes, social influences and self-efficacy expectations will be the content of these personalised feedback letters. Pupils in the intervention + prompt condition will - in addition to the personalised feedback letters - receive e-mail and SMS messages prompting them to revisit the ‘Fun without Smokes’ website. The main outcome measures will be ever smoking and the utilisation of the ‘Fun without Smokes’ website. Measurements will be carried out at baseline, 12 months and 24 months of follow-up. Discussion The present study protocol describes the purpose, intervention design and study protocol of ‘Fun without Smokes’. Expectations are that pupils receiving tailored advice will be less likely to smoke after 24 months in contrast to pupils in the control condition. Furthermore, tailored feedback letters and prompting is expected to be more effective than providing tailored feedback letters only. Trial registration Dutch Trial Register NTR3116 PMID:22490110

Age- and region-specific imbalances of basal amino acids and monoamine metabolism in limbic regions of female Fmr1 knock-out mice.

PubMed

Gruss, Michael; Braun, Katharina

2004-07-01

The Fragile X syndrome, a common form of mental retardation in humans, originates from the loss of expression of the Fragile X mental retardation gene leading to the absence of the encoded Fragile X mental retardation protein 1 (FMRP). A broad pattern of morphological and behavioral abnormalities is well described for affected humans as well as Fmr1 knock-out mice, a transgenic animal model for the human Fragile X syndrome. In the present study, we examined neurochemical differences between female Fmr1 knock-out and wildtype mice with particular focus on neurotransmission. Significant age- and region-specific differences of basal tissue neurotransmitter and metabolite levels measured by high performance liquid chromatography were found. Those differences were more numerous in juvenile animals (postnatal day (PND) 28-31) compared to adults (postnatal day 209-221). In juvenile female knock-out mice, especially aspartate and taurine were increased in cortical regions, striatum, cerebellum, and brainstem. Furthermore, compared to the wildtype animals, the juvenile knock-out mice displayed an increased level of neuronal inhibition in the hippocampus and brainstem reflected by decreased ratios of (aspartate + glutamate)/(taurine + GABA), as well as an increased dopamine (DA) turnover in cortical regions, striatum, and hippocampus. These results provide the first evidence that the lack of FMRP expression in female Fmr1 knock-out mice is accompanied by age-dependent, region-specific alterations in brain amino acids, and monoamine turnover, which might be related to the reported synaptical and behavioural alterations in these animals.

Polysaccharides including β-glucans are important bioactive components of mushroom. Xylaria nigripes is a popular medicinal fungus that has been used for treating trauma, insomnia and mental illness. This study examined the physicochemical characteristics and anti-inflammatory activities of water soluble non-digestible polysaccharides (TXNP and CXNP) from fruiting bodies of two cultivated X. nigripes strains (TXN and CXN). Results showed that both TXNP and CXNP possessed relatively similar FT-IR spectra. TXNP had a triple helix conformation and molecular weight of 853.8 kDa, whereas the molecular weight of CXNP was 14.7 kDa. The monosaccharide composition of TXNP was predominantly glucose, whereas CXNP contained xylose, mannose and glucose. Although both TXNP and CXNP dose-dependently suppressed the production of NO, IL-1β, TNF-α and PGE2, as well as the expression of iNOS, COX-2 and NF-κB in the lipopolysaccharide-induced RAW264.7 macrophages, the potency of TXNP was stronger. This study reveals that under similar conditions of cultivation and extraction procedures, the different physicochemical characteristics of polysaccharides from TXN and CXN may have contributed to the differences in their anti-inflammatory potency.

Maternal infection during pregnancy may affect fetal brain development and lead to neurological and mental disorders. Previously, we used lipopolysaccharide [LPS, 33 μg/kg, intraperitoneal injection] exposure on gestation day 10.5 to mimic maternal bacterial infection in rats and found reduced dopaminergic and serotoninergic neurons in the offspring. In the present study, we examined the anxiety and stress responses of the affected offspring and the neurophysiological changes in their brains. Our results show that LPS rats displayed more anxiety-like behaviors and heightened stress responses. Dopamine (DA) in the nucleus accumbens and serotonin (5-HT) in the medial prefrontal cortex and the hippocampus were significantly reduced in LPS rats. Their glucocorticoid receptors in the dorsal hippocampus and the 5-HT(1A) receptors in the dorsal and ventral hippocampus were also reduced. In addition, chronic but not acute fluoxetine treatment reversed the behavioral changes and increased hippocampal 5-HT(1A) receptor expression. This study demonstrates that LPS exposure during a critical time of embryonic development could produce long-term reduction of DA and 5-HT and other neurophysiological changes; such alterations may be associated with the increases in stress response and anxiety-like behaviors in the offspring.
