Efeitos preventivos do exercício físico na expressão da miostatina em ratos tratados com Dexametasona

Muscle atrophy is always associated with Dexamethasone (Dexa) treatment, however the mechanisms are not completely understood. This study investigated the effects of Dexa on myostatin and p70S6K protein expression and if previous exercise training (T) can attenuate these effects. Eighty rats were distributed into 4 groups: sedentary control (SC), sedentary treated with Dexa (SD; 0,5 mg/kg per day, i.p., 10 days), trained control (TC) and trained treated with Dexa (TD) and underwent a training period where they were either submitted to a running protocol (60% of physical capacity, 5 days/week for 8 weeks) or kept sedentary. After T period, animals underwent Dexa treatment concomitant with training. Western Blot was performed to identify myostatin and p70S6k protein expression in the tibialis anterior (TA) and soleus (SOL) muscle. Ten days of Dexa treatment increased fasting glucose (SD=+62%), however previous T attenuated this increase (TD=+20%, p<0.05). Dexa determined significant decrease in body weight in TD (-22%) and SD (-25%), followed by TA weight reduction in SD (-23%) and TD (-20%). Previous training could not avoid these decreases. Myostatin protein expression was not altered by dexa treatment or training in TA muscle but in SOL muscle it was significantly modified after T, regardless of treatment (TC=+%23 and TD=+25) compared with their respective controls. The protein p70S6K was not modified neither by dexa nor training in any of the analyzed muscle or condition. The results of this study allowed us to conclude that previous training attenuates the hyperglycemia induced by Dexa, however it did not prevent the body or muscle weight reductions. Even in the presence of muscle atrophy, the expression of myostatin and p70S6K do not justify the mechanisms of muscle loss induced by Dexa, which suggests that other catabolic or anabolic proteins could be involved in the process of muscle atrophy after 10 days of treatment with Dexa

Depression and anxiety in pregnant women with diabetes or mild hyperglycemia

A number of physical and psychological changes that occur during pregnancy can stimulate the development of psychological disorders such as anxiety and depression. The study evaluated psychological aspects related to maternal depression and anxiety in pregnant women with diabetes mellitus or hyperglycemia, contrasting the results with those of non-diabetic pregnant women. In a prospective and longitudinal approach, two questionnaires were applied and validated for use in Brazil, the Beck depression inventory and the State-Trait Anxiety Inventory. The questionnaires were applied to pregnant women at the first prenatal visit or at the time of disease diagnosis (T1) and reapplied at admission for delivery (T2). Regardless of the degree of hyperglycemia, both at first and in the second stage most women had severe anxiety trait. In early pregnancy (T1), however, severe state anxiety was more frequent in women with hyperglycemia than in those from the NG group. Most pregnant women showed moderate state anxiety over their pregnancy, regardless of glycemic status. In early pregnancy, however, severe state anxiety was more prevalent in hyperglycemic women than in those with normal glycemic status. Most women showed moderate trait anxiety and mild depression in both early and late pregnancy, irrespective of glycemic status. The incidence of severe state anxiety in early pregnancy is more frequent in women with diabetes or hyperglycemia, but their levels of trait anxiety and depression are not affected by glycemic status.

Análise do processo histórico da identificação de goleiros para o futebol

The purpose of the present research, of qualitative nature, was to analyzethe historical process of talent selection in soccer, specifically, themethodology used to identify goalkeepers, used by professionals who workedin Brazilian soccer clubs in the period of 1970 to 2005. Through the techniqueof semi-structured interviews, were collected the testimony of thirteenprofessionals who worked in soccer during the stated period. It was foundthat the process of identifying goalkeepers occurred predominantly duringthe collective training (traditional game) and the specific position training, inwhich technical fundamentals are observed. It was also found that theanthropometric characteristics (height) and the psychological aspects werementioned by respondents as the most observed ones in the process ofidentifying goalkeepers.

Influência de aspectos psicológicos nos praticantes de musculação

This paper deals with psychological aspects involving bodybuilders nowadays, through their interests, motivations, factors that favor them to practice physical activity, frequent body image disorders, and major benefits that can be acquired when weight training the right way, whether physical or psychological. During the work is addressed to the Theory of Self-Determination and its characteristics, and behavioral aspects of the individual. We explore the types of motivation, intrinsic and extrinsic motivation, and their regulatory mechanisms. Did the relationship with weight training and the environment that surrounds it as the interaction between those involved in practice between the student and teacher performance and results and the effects that this interference can have on motivation and individual behavior. Also we relate body image factors, the perception of bodybuilders in relation to his own body, and the possible disorders that can promote. Describe the Vigorexia and their characteristics, we made a list of body image and self-esteem, approach standards set by society, the aesthetic influence and media disclosure. Finally, we explore the key benefits that well-directed physical activity can provide its practitioners. Physical, mental and social beneficial, improved self-esteem and in one's relationship skills. We address the growing strength in recent years, and their improvements in the various age groups and the population's quality of life

Autismo: aspectos cognitivos, educacionais e neurobiológicos com base na análise dos livros Mundo singular: entenda o autismo e o Os gatos nunca mentem sobre o amor e na literatura especializada

The autism is a severe mental illness that involves psychological, social, educational and neurobiological aspects. The Education plays an important role in recovering, preserving and increasing the cognitive task of people with autism. There are several ways to observe a person with autism. Through the studying of cases, it is also possible to address issues of everyday life of the person with the illness, its cognitive issues and its obstacles of psychosocial involvement, as well as psychological aspects such as illness acknowledgement. Through specialized literature, it is possible to identify characteristics referring to the learning process and neurobiological components involved in the condition, such as brain activity disorder and genetic factors. The objectives of this paper are: from the analysis of two books: Unique World: comprehend the Autism (SILVA, A. B. B; GAIATO, M.B; REVELES, L.T) and The cats never lie about love (DILLON, J.), it is intended to describe cognitive and psychosocial aspects of the autism. Based on the specialized literature, the goal is to identify cognitive and neurobiological components in the illness. The methods that were used: analysis of the books Unique World: comprehend the Autism and The cats never lie about love to describe psychosocial and educational aspects of the autism; analysis of the specialized literature to identify clinical and neurobiological components of the illness, such as changes in brain activity, genetic factors or clinical evolution; and also details of the Education role in preserving the person with autism and his cognitive and emotional development. The study had the documentary research as reference for the methodological design, including book analysis and research in specialized literature. It is intended to deepen discussions about the Education roles related to the cognitive and neurobiological aspects of the autism

Estresse psicológico e desempenho de atletas juniores: uma análise documental

Soccer is one of the most practiced sports in the world, and for many years, some areas of physical education has been doing studies related to the improvement of their income from these areas if this sport psychology. The psychological aspects are very influential and involved in the daily life of an athlete, especially for basic categories of athletes who see in soccer a dream to come true or only a source of income for his family, where such aspects act beneficially or evil for the athlete. Stress, in particular, can appear in various situations and in various ways, and different influences and reactions athlete to athlete, also resulting in physiological changes and variations in performance. Stress, and especially stressful situations, like any psychological aspect should be identified in order to train your athlete to know how to deal with stressful situations. Know what are the stressors, which carries the stress load for the athlete, how to handle the stressful situations, using psychological training in the preseason, know how to use stress management techniques, and be able to manage it all so your athlete reaches an optimal level of income is described in the present work, in order to provide a theoretical and updated reference for professionals of Physical Education, so that they stay up to date on sports psychology and also understand a little more on this subject, which is still little discussed within soccer and often overlooked by many professionals who are already in the context of competitive soccer

Well-being, distress and health status in a population of adolescent students

The present work explores the psychosocial issues emerging from a large cross-sectional study aimed to assess the prevalence, clinical manifestations, and psychosocial correlates of hyperandrogenism in a population of Italian high school students. Participants were 1804 adolescents, aged between 15 and 19 years, who volunteered to fill in a package of self-report questionnaires (including the Psychosocial Index, the Symptom Questionnaire and Ryff’s Psychological Well-Being scales for the assessment of psychological aspects) and undergo a comprehensive physical examination. Significant gender differences were found with regard to psychological distress, with females reporting higher scores compared with males, but not on well-being dimensions. The relationships of well-being to distress were found to be complex. Although inversely associated, well-being and ill-being appeared to be distinct domains of mental functioning. The evaluation of the moderating effects of well-being in the association between stress and psychological distress indicated that well-being may act as a protective factor, contributing to less pronounced psychological distress as stress levels increased. Higher rates of somatic complaints were found among current smokers. However, substance use (i.e., smoking and drug use) was also found to be positively associated with some well-being dimensions. A considerable number of participants were found to present with disordered eating symptoms, particularly females, and associated higher stress levels and lower quality of life. Sport activities were found to favourably affect psychological health. As to clinical signs of hyperandrogenism, a significant impairment in psychosocial functioning was found among females, whereas no effects on psychological measures could be detected among males. Subgroups of adolescents with distinct clinical and psychological characteristics could be identified by means of cluster analysis. The present study provides new insights into better understanding of the complex relationships between well-being, distress and health status in the adolescent population, with important clinical implications.

Bone-marrow derived progenitor cells are associated with psychosocial determinants of health after controlling for classical biological and behavioral cardiovascular risk factors

BACKGROUND: Circulating progenitor cells have been implicated with maintaining vascular integrity. Low counts are found in adults with high cardiovascular risk and are associated with impaired endothelial function. It remains unknown whether psychosocial risk factors are independently related to counts of circulating progenitor cells. METHODS: We investigated a random sample of 468 adult industrial employees (mean age 41.2 years, 89% men) of Caucasian origin. Cardiovascular risk factors (blood pressure, LDL, HDL and C-reactive protein), health behavior (smoking, alcohol and physical exercise), psychological variables (effort-reward imbalance social support, negative affectivity) and interaction terms served as predictors of circulating progenitor cells (CD34+ CD31dim) as enumerated by flow-cytometry. FINDINGS: Psychosocial variables were independently associated with progenitor cell counts. The association with risk factors increased with age (explained variance in 18-36 year olds R(2)=0.17, p=0.55; age 36.1-46 R(2)=0.32, p=0.001; age>46 R(2)=0.27, p<0.001). Data revealed a shift from a larger association between behavioral and psychosocial variables and cell counts to a stronger association between biological variables and cell counts in older individuals. A significant interaction was observed between smoking and effort-reward imbalance in middle-aged subjects, those with both risk factors present had lower cell counts. In older employees, the interaction between biological risk factors and smoking was related to lower cell counts. INTERPRETATION: In working middle-aged and older men, psychosocial risk factors were related to circulating counts of progenitor cells. Smoking interacted negatively with psychosocial risk factors (middle-aged men) or with biological risk factors (older employees).

Associative processing and paranormal belief

In the present study we introduce a novel task for the quantitative assessment of both originality and speed of individual associations. This 'BAG' (Bridge-the-Associative-Gap) task was used to investigate the relationships between creativity and paranormal belief. Twelve strong 'believers' and 12 strong 'skeptics' in paranormal phenomena were selected from a large student population (n > 350). Subjects were asked to produce single-word associations to word pairs. In 40 trials the two stimulus words were semantically indirectly related and in 40 other trials the words were semantically unrelated. Separately for these two stimulus types, response commonalities and association latencies were calculated. The main finding was that for unrelated stimuli, believers produced associations that were more original (had a lower frequency of occurrence in the group as a whole) than those of the skeptics. For the interpretation of the result we propose a model of association behavior that captures both 'positive' psychological aspects (i.e., verbal creativity) and 'negative' aspects (susceptibility to unfounded inferences), and outline its relevance for psychiatry. This model suggests that believers adopt a looser response criterion than skeptics when confronted with 'semantic noise'. Such a signal detection view of the presence/absence of judgments for loose semantic relations may help to elucidate the commonalities between creative thinking, paranormal belief and delusional ideation.

The Moldable Inspector: a framework for domain-specific object inspection

Answering run-time questions in object-oriented systems involves reasoning about and exploring connections between multiple objects. Developer questions exercise various aspects of an object and require multiple kinds of interactions depending on the relationships between objects, the application domain and the differing developer needs. Nevertheless, traditional object inspectors, the essential tools often used to reason about objects, favor a generic view that focuses on the low-level details of the state of individual objects. This leads to an inefficient effort, increasing the time spent in the inspector. To improve the inspection process, we propose the Moldable Inspector, a novel approach for an extensible object inspector. The Moldable Inspector allows developers to look at objects using multiple interchangeable presentations and supports a workflow in which multiple levels of connecting objects can be seen together. Both these aspects can be tailored to the domain of the objects and the question at hand. We further exemplify how the proposed solution improves the inspection process, introduce a prototype implementation and discuss new directions for extending the Moldable Inspector.

How narcissistic self-construction sabotages their relationships: Accuracy and bias in partner perception

Trapped by their superordinate goal to maintain a grandiose self, narcissists navigate their relationships wishing to re-assure themselves of their specialness and superiority, using strategies bound to fail. Dyadic analyses of diary data (14 days, 83 couples) showed that narcissists focus on their partners’ shortcomings, becoming experts at detecting negative forms of support, while simultaneously minimizing their partner’s positive intentions. Partners of narcissists, in contrast, appear to have a positive bias in ongoing relationships and seem to compensate for some of the narcissists’ shortcomings. Narcissists’ focus on their own selfconstruction purposes also extends to their parenting roles. In a retrospective study, narcissistic mothers were found to demand superior performance, desiring to show-off their child, yet concurrently attributing their child’s success to themselves. They also exercise psychological control and role-reversal, requiring the child to cater to their needs, and to admire them, while simultaneously oblivious to their child’s needs and desires.

Análisis cuantitativo y cualitativo de los momentos críticos en baloncesto = Quantitative and qualitative analysis of the critical moments in basketball

El MC en baloncesto es aquel fenómeno relacionado con el juego que presenta unas características particulares determinadas por la idiosincrasia de un equipo y puede afectar a los protagonistas y por ende al devenir del juego. En la presente Tesis se ha estudiado la incidencia del MC en Liga A.C.B. de baloncesto y para su desarrollo en profundidad se ha planteado dos investigaciones una cuantitativa y otra cualitativa cuya metodología se detalla a continuación: La investigación cuantitativa se ha basado en la técnica de estudio del “Performance analysis”, para ello se han estudiado cuatro temporadas de la Liga A.C.B. (del 2007/08 al 2010/11), tal y como refleja en la bibliografía consultada se han tomado como momentos críticos del juego a los últimos cinco minutos de partidos donde la diferencia de puntos fue de seis puntos y todos los Tiempos Extras disputados, de tal manera que se han estudiado 197 momentos críticos. La contextualización del estudio se ha hecho en función de la variables situacionales “game location” (local o visitante), “team quality” (mejores o peores clasificados) y “competition” (fases de LR y Playoff). Para la interpretación de los resultados se han realizado los siguientes análisis descriptivos: 1) Análisis Discriminante, 2) Regresión Lineal Múltiple; y 3) Análisis del Modelo Lineal General Multivariante. La investigación cualitativa se ha basado en la técnica de investigación de la entrevista semiestructurada. Se entrevistaron a 12 entrenadores que militaban en la Liga A.C.B. durante la temporada 2011/12, cuyo objetivo ha sido conocer el punto de vista que tiene el entrenador sobre el concepto del MC y que de esta forma pudiera dar un enfoque más práctico basado en su conocimiento y experiencia acerca de cómo actuar ante el MC en el baloncesto. Los resultados de ambas investigaciones coinciden en señalar la importancia del MC sobre el resultado final del juego. De igual forma, el concepto en sí entraña una gran complejidad por lo que se considera fundamental la visión científica de la observación del juego y la percepción subjetiva que presenta el entrenador ante el fenómeno, para la cual los aspectos psicológicos de sus protagonistas (jugadores y entrenadores) son determinantes. ABSTRACT The Critical Moment (CM) in basketball is a related phenomenon with the game that has particular features determined by the idiosyncrasies of a team and can affect the players and therefore the future of the game. In this Thesis we have studied the impact of CM in the A.C.B. League and from a profound development two investigations have been raised, quantitative and qualitative whose methodology is as follows: The quantitative research is based on the technique of study "Performance analysis", for this we have studied four seasons in the A.C.B. League (2007/08 to 2010/11), and as reflected in the literature the Critical Moments of the games were taken from the last five minutes of games where the point spread was six points and all overtimes disputed, such that 197 critical moments have been studied. The contextualization of the study has been based on the situational variables "game location" (home or away), "team quality" (better or lower classified) and "competition" (LR and Playoff phases). For the interpretation of the results the following descriptive analyzes were performed: 1) Discriminant Analysis, 2) Multiple Linear Regression Analysis; and 3) Analysis of Multivariate General Linear Model. Qualitative research is based on the technique of investigation of a semi-structured interview. 12 coaches who belonged to the A.C.B. League were interviewed in seasons 2011/12, which aimed to determine the point of view that the coach has on the CM concept and thus could give a more practical approach based on their knowledge and experience about how to deal with the CM in basketball. The results of both studies agree on the importance of the CM on the final outcome of the game. Similarly, the concept itself is highly complex so the scientific view of the observation of the game is considered essential as well as the subjective perception the coach presents before the phenomenon, for which the psychological aspects of their characters (players and coaches) are crucial.
