A insuficiência cardíaca (IC) está associada à miopatia dos músculos esqueléticos com aumento da expressão das isoformas rápidas da cadeia pesada de miosina e alterações na matriz extracelular. Os fatores de regulação miogência(MRF),como a MyoD e MRF4, pertecem a uma família de fatores transcricionais que controlam vários genes músculo-específicos.Esses fatores forma heterodímeros com proteínas HLH e ligam-se a seqüências de DNA conhecidas como Ebox, presentes na região promotora de vários genes músculo–específicos, incluindo todos aqueles que codificam as subunidades dos receptores nicotínicos de acetilcolina (nAChR) da junção neuromuscular (JNM). Baseado no fato de que na IC há uma diminuição na expressão da MyoD e MRF4 no músculo sóleo de ratos com IC induzida por monocrotalina, o objetivo do presente trabalho é verificar possíveis alterações na expressão dos receptores de acetilcolina, bem como realizar uma análise morfológica e morfométrica das JNMs. Neste estudo foram utilizados ratos Wistar, machos, divididos em grupos controle e experimental e a Insuficiência cardíaca (IC) foi induzida pela injeção de monocrotalina intra-peritoneal.Quando os sintomas de IC foram visualizados (após 22 dias) os animais foram sacrificados pentobarbital sódico i.p. (50 mg/Kg). A seguir foram mensurados o peso corporal (PC) dos ratos, bem como outros parâmetros. O músculo sóleo de ambos os antímeros foram dissecados e preparados para: avaliação da expressão gênica das subunidades ε, γ e α dos receptores de acetilcolina por PCR em Tempo Real; para análise morfológica e morfométrica da Junção Neuromuscular através da técnica de Esterase inespecífica; para análise ultra-estrutural da JN. Os resultados indicam que não houveram alterações morfológicas e morfométricas na JN, mas houve um aumento... (Resumo completo, clicar acesso eletrônico abaixo)

Regular physical activity can prevent and treat various diseases and non-communicable diseases such as diabetes, hypertension, obesity and cardiovascular disease. However, the prevalence of physical inactivity among adolescents in Rio Claro is 83%. Thus, it is necessary to encourage physical atividade through the community, especially parents and schools. The objective was to investigate the influence of two types of gym class in functional abilities in high school students in the city of Rio Claro-SP. Methodology: The study included 20 students from high school, 8 boys and 12 girls. The study took place in two high school halls of a public school in the city of Rio Claro. With the collaboration and participation in only 10 students in each room search reviews of all students occurred in mid-July in the year 2012 with the completion of the battery of tests and application of PAQ-C questionnaire at the beginning of classes of and after three months. All students were subjected to the test battery Eurofit. To compare the values of physical fitness for each type of class was held factorial ANOVA for repeated measures using SPSS and the level of physical activity was performed the Wilcoxon test. To compare the delta values (post-test-time time pre test every physical fitness) we performed the t test for all analyzes was adopted p <0.05 Classes G1 followed the schedule proposed by the state 's Notebook, where he worked subjects as body and beauty and its relationship with the media today, prevailing more conceptual classes than procedural . Unlike what has been developed with the G2 who had classes were focused on physical fitness and physical conditioning to increase the level of physical activity inside and outside the school environment . Result :The results from the data collected in this study indicate that physical fitness is not worked continuously or expressive within the Physical Education classes of high school to the population...

Although the use of countertransference is a controversial topic and the debate on the participation of the analyst’s mind may go back to the old conception of aptness for the analytical task based on personality or psychological makeup, the fact is that the psychoanalyst’s education involves the elaboration of his unconscious conflicts, turning conscious the pathways of his desire and his symptoms through a process of personal analysis and a long theoretical and technical training in the field of psychoanalysis. This study is a literature review based on studies about the maternal function, which aims at showing the path of recovery of countertransference in psychoanalytic theory and technique and the implication of the analyst’s abilities in the analytical process. This development is tributary of the appreciation of maternal function as a model for interpersonal and therapeutic relationship in Psychoanalysis, due to the paradigm of object relations in the British psychoanalytic tradition, being Donald W. Winnicott and Wilfred R. Bion two of its main authors.
