Según el Plan de estudios 435/03 del Profesorado en Educación Física que se dicta en el Centro Regional Universitario Bariloche dependiente de la Universidad Nacional del Comahue existe, en los trayectos formativos de primer, segundo y tercer año, una asignatura cuya denominación es Formación Corporal Motora en adelante (FCM). En la misma se ha intentado, durante estos años, articular disciplinas deportivas como el Atletismo, la Gimnasia y la Natación. En esta comunicación se trata el encuadrede conocimiento que se desarrolla en la asignatura FCM3 del tercer nivel de la formación, planteando un espacio diferente respecto a la construcción de corporeidad y motricidad del sujeto. Se plantea como alternativa a las perspectivas gimnástica- higienista y físico-deportiva en la formación de profesionales de la Educación Física.Entonces ¿cómo se visibiliza la formación corporal motora del sujeto desde la enseñanza de las destrezas en las diversas propuestas pedagógicas? En este sentido, nada de lo que se lleve adelante en la enseñanza es ni neutral ni inocente,está teñido de sentido, de significado, de poder y de utopía. Siguiendo a Zerbino el reto es preguntarse ¿"qué estamos sosteniendo con aquello que hacemos"?

Parkinson disease (PD) is associated with motor symptoms and dopaminergic cell loss in the nigrostriatal pathway. Alpha-synuclein is the major component of the Lewy bodies, the biological hallmarks of disease, and has been associated with familial cases of PD. Recently, the spinal cord stimulation (SCS) showed to be effective to alleviate the Parkinson symptoms in animal models and human patients. In this project, we characterized the motor and electrophysiological effects of alpha-synuclein overexpression in the substantia nigra of rats. We further investigated the effects of spinal electrical stimulation, AMPT and L-dopa administration in this model. Method: Sprague-Dawley rats were injected with empty viral vector or the vector carrying the gene for alpha-synuclein in the substantia nigra, and were tested weekly for 10 weeks in the open field and cylinder tests. A separated group of animals implanted with bilateral electrode arrays in the motor cortex and the striatum were recorded in the open field, during the SCS sessions and the pharmacological experiments. Results: Alpha-synuclein expression resulted in motor asymmetry, observed as the reduction in use of contralateral forepaw in the cylinder test. Animals showed an increase of local field potential activity in beta band three and four weeks after the virus injection, that was not evident after the 5th week. AMPT resulted in a sever parkinsonian state, with reduction in the locomotor activity and significant peak of oscillatory activity in cortex and striatum. SCS was effective to alleviate the motor asymmetry at long term, but did not reduce the corticostriatal low frequency oscillations observed 24 hs after the AMPT administration. These oscillations were attenuated by L-dopa that, even as SCS, was not effective to restore the locomotor activity during the severe dopaminergic depletion period. Discussion: The alpha-synuclein model reproduces the motor impairment and the progressive neurodegenerative process of PD. We demonstrated, by the first time, that this model also presents the increase in low frequency oscillatory activity in the corticostriatal circuit, compatible with parkinsonian condition; and that SCS has a therapeutic effect on motor symptom of this model.

Introduction: Several modifications are identified as aging, causing more or less limitation imposed by over the years. Among these, one can highlight the different degrees of cognitive decline, particularly memory that can involve the daily activities and the subject functionality. Studies have shown an association between levels of serum cortisol and stress imposed by the exercise on this. However, there are few studies that references the performance on cognitive aspects of declarative memory and cortisol on the exercise in the water with automatic and práxicos movements and moderate. Objective: Check the effect based on the acute physical exercise and práxicos automatic movements on the performance of visual declarative memory and in serum cortisol in subjects aged between 51 and 74 years. Materials and Methods: It builds a survey characterized as cross with a first sample of 32 physically active subjects aged between 51 and 74 years, divided into two exercise groups (March of Automatic Group - MAG and the March of Praxis Group - MPG). We used a probabilistic and random sampling for sample selection. Used the MMSE (Mini Mental State Examination) to check the general cognitive status, visual acuity test - optotypes chart "E" Rasquin and was even used the declarative visual memory test proposed by Nitrini and collaborators (1994), applying before motor stimulation and immediately after, and the day of blood collection with 2 ml for analysis of cortisol hormone. The normality and homogeneity were verified from the Shapiro-Wilk and Levene tests. Thus we adopted a descriptive statistics to characterize the sample. The Split-Plot ANOVA was used along with the paired t-test to verify the identified differences. We adopted a significance level of p <0.05. Results: It was observed that the groups (MAG and MPG) and the anthropometric variables, perceived exertion, education, cognitive assessment and visual acuity showed no significant differences (p > 0.05), showing that the groups are homogeneous, with variables and similar means. After the stimulation session, lasting 30 min, it was observed that the amount of hits for Δ of declarative memory questionnaire visual images increased, presenting significant for both groups (MAG, p < 0.001; MPG, p = 0.042). The same was observed for cortisol concentration with a reduction in the levels immediately after the stimulus (MAG and MPG, p < 0.001). Conclusion: The results showed that the exercises proposed in its acute effect provide significantly memories of gains and also showed a reduction in cortisol levels.

This work evaluated the fresh, spray dried (with 10 % of Arabic Gum) and freeze dried jambolan pulp (Eugenia jambolana Lam.) in regard to physicochemical (pH, moisture, water activity, average particle diameter, solubility and color), bioactive [total phenolic content (TPC), monomeric anthocyanin, pronathocyanidin (PA), total elagic acid (TEA), myricetin and cyanidin] and in vitro functionality (antioxidant, antienzymatic and antimicrobial activities]. In addition, the in vivo functionality of jambolan pulp was investigated using the Caenorhabditis elegans model for insulin signaling, longevity and induced neurodegeneration (Alzheimer’s disease and Parkinson’s disease related symptoms). The dried jambolan pulp presented TPC retention (50% to 75%), PA (90% to 98%), TEA (31% to 83%), myricetin (40% to 84%), cyanidin (72% to 84%) and antioxidant activity (15%). The fresh jambolan pulp, the freeze dried pulp and the spray dried jambolan pulp presented high enzymatic inhibitory activity against pancreatic lipase (4,4 to 5,8 mg/mL), alpha-glycosidase (10,3 to 13,8 mg/mL) and alpha-amylase (8,9 to 11,2 mg/mL). They also were active inhibitors against the pathogen S. aureus. The dried jambolan experimental samples were able to increase the expression of several genes linked to the insulin signaling pathways (SIR-2.1, PPTR-1, DAF-16, SOD-3, e CTL) and increased the lifespan in C. elegans (18,07 % - 24,34 %), besides decreasing the amyloid AB1-42 aggregation induced paralysis and MPP+ (1-methyl-4-phenylpyridinium) induced neurodegeneration. Based on that, the jambolan pulp and the spray dried jambolan pulp were further selected for the production of caprine frozen yogurt with the addition of Bifidobacterium animalis subsp. lactis BI-07. The final product were evaluated in regard to their physicochemical (pH, acidity, total solids, protein, total reducing sugars, fat, ashes, overrun, melting test), bioactive (TPC and monomeric anthocyanin, antioxidant activity, probiotic viability and sensory analysis (sensory acceptance). The results showed that samples with probiotic had lowest pH and higher acidity, TPC, anthocyanin and antioxidant activity. It was also observed low overrun (14.2% to 22.6%). vi Samples with probiotic had lower flavor scores. Overall, this research presents the jambolan as a highly functional bioactive-rich fruit with the potential to modulate important biological pathways, extend lifespan and retard the development of neurodegenerative diseases. Jambolan is an underexploited exotic fruit with a high colorant potential and this thesis shows for the first time in the literature important technological, biological and scientific data about this fruit that could be used towards the development of health-oriented food products.

O objectivo deste estudo consiste em avaliar o desporto adaptado como factor de integração social da pessoa com deficiência motora, nomeadamente dos atletas praticantes no Centro de Medicina de Reabilitação da Região Centro - Rovisco Pais (CMRRC-RP), baseando-se nos princípios orientadores de uma política de desporto para todos. Assim, a trajectória do desporto adaptado e sua importância aos níveis de integração social individual e/ou colectivo das pessoas com deficiência motora permite compreender e analisar os factores intervenientes na integração de pessoas com deficiências, tendo em linha de conta os programas de desporto adaptado promovidos pelas políticas públicas em vigor e sua receptividade pelos praticantes, identificando os obstáculos ou constrangimentos que se colocam para a prática de desporto adaptado. Neste estudo qualitativo, os resultados obtidos através das 12 entrevistas realizadas aos atletas praticantes de desporto adaptado no CMRRC-RP, sugerem que o desporto adaptado está intrinsecamente ligado ao domínio da saúde e da reabilitação. Os principais resultados sublimam que o desporto adaptado desenvolvido no CMRRC-RP pressupõe uma medida efectiva de aplicação de política social de direito, reconhecendo o papel do desporto como um meio de integração social da pessoa com deficiência motora. Observam-se ainda, inúmeros efeitos com a prática do desporto adaptado a vários níveis considerando-se a reabilitação como um processo físico, psicológico, social, vocacional e educacional, compatível com o seu deficit fisiológico ou anatómico, limitações ambientais, desejos e planos de vida.

The titanium and titanium alloys are widely used as biomaterial in biomedical device and so research have been developed aiming to improve and/or better to understand interaction biomaterial/biological environment. The process for manufacturing of this titanium implants usually involves a series of thermal and mechanical processes which have consequence on the final product. The heat treatments are usually used to obtain different properties for each application. In order to understand the influence of these treatments on the biological response of the surface, it was done, in this work, different heat treatments in titanium and analyzed their influence on the morphology, adhesion and proliferation of the pre-osteoblastic cells (MC3T3-E1). For such heat-treated titanium disks were characterized by optical microscopy, contact angle, surface energy, roughness, microhardness, X-ray diffraction and scanning through the techniques (BSE, EDS and EBSD). For the analysis of biological response were tested by MTT proliferation, adhesion by crystal violet and β1 integrin expression by flow cytometry. It was found that the presence of a microstructure very orderly, defined by a chemical attack, cells tend to stretch in the same direction of orientation of the material microstructure. When this order does not happen, the most important factor influencing cell proliferation is the residual stress, indicated by the hardness of the material. This way the disks with the highest level state of residual stress also showed increased cell proliferation

Os sistemas ambientais físicos representam a organização geográfica resultante da interação dos componentes físicos da natureza. Esses sistemas possuem expressão espacial na superfície terrestre e, como qualquer outro sistema, funcionam através de fluxos de energia e matéria. Analisados sob a perspectiva geográfica com fins na atividade de planejamento e gestão territorial, este estudo trata das características e complexidades dos elementos físicos no contexto espacial da região do São Francisco Sergipano, localizada ao norte do estado de Sergipe/Brasil, constituída por 27 municípios e subdividida em três territórios (alto sertão, médio e baixo). Para atingir aos objetivos propostos utilizou-se distintos procedimentos metodológicos, entre eles o trabalho de campo, associado ao levantamento de dados secundários e cartográficos. Entre outros aspectos, verificou-se que a região em apareço, sobretudo no Baixo São Francisco, de maior vulnerabilidade ambiental, apresenta problemas ambientais capazes de originar sérios conflitos cujos interesses são representados por diferentes atores sociais quanto à utilização dos recursos naturais ou até mesmo a gestão do meio ambiente. Os impactos ambientais emergentes relacionados aos riscos ambientais merecem especial atenção pelos gestores públicos municipais nas localidades da região em que se cogitam os riscos de ocorrência de acidentes.

[Es] El autoconcepto físico juega un papel decisivo en el bienestar personal y la prevención de trastornos y dificultades de conducta. De ahí la importancia de ayudar educativamente al desarrollo de adecuadas autopercepciones físicas. En este artículo se ofrece un análisis comparativo de dos formatos (papel y on line) de un mismo programa de intervención educativa para la mejora del autoconcepto implementado con estudiantes universitarios. Los datos obtenidos en la medida del autoconcepto físico no confirman una mejora significativa, lo cual no necesariamente desacredita el programa ya que puede atribuirse en parte a determinadas limitaciones observadas en la aplicación del mismo. Por otra parte, la valoración del programa que realizan los sujetos participantes es notablemente positiva, en particular, la de quienes han utilizado la versión on line.
