Efeito agudo do exercício físico associado a praxias ideomotoras sobre as concentrações séricas de cortisol e memória declarativa em indivíduos com idade entre 51 e 74 anos

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.

Fenótipo neuropsicológico de adolescentes com síndrome de Down

This research aimed to contribute to the characterization of a neuropsychological phenotype of adolescents with Down Syndrome (DS). A multicases study of six adolescents (three males and three females, aged 13 to 14 years) diagnosed with DS and treated at two institutions in the city of Natal (Brazil), was conducted. Participants were assessed using the methodological approach developed by Luria, which is composed by four complementary stages. The first one aimed to investigate the qualitative impact of DS in school life and social development of the adolescents; dimensions of behavior and social-affective aspects of the members of the study were investigated. In the second stage participants performed a battery of neuropsychological tests in order to identify strengths and weaknesses in their cognitive functioning. The third stage was incorporated into the second in order to analyze the quality of the activity of the participants along the quantitative evaluation, highlighting strategies used, errors produced among other indicators. Lastly, the fourth stage refers to the intervention with the participants. Although this is not a specific objective of the study, it is argued that the outcome of this research will subsidize the practice of different professionals working with this clinical group. The results of the first stage emphasized the presence of difficulties in social relationships and in school life of observed adolescents. In turn, the second and third stages pointed out to the presence of difficulties in tasks involving logical and abstract thinking, as well as difficulties in expressive language. In relation to visual memory, we observed a better performance in activities of lower complexity, ie, with less interference of executive functioning, particularly in terms of the functions of planning and initiative. Finally, it was found motor and mental retardation, affecting significantly the performance related to different cognitive areas. The results highlighted here can be considered as subsidies for future interventions, suggesting the need for developping projects that take into account different aspects constituents of the human subject, involving not only the individual with developmental changes, as well as their families, teachers, schools and society in general

Etnografia visual das mangabeiras nas matas do tabuleiro costeiro.

This work is an ethnographic research with collectors women of Mangaba in the village of Ponta Negra in Natal - RN. This Women also known as Mangabeira's women reproduce a practice learned with their ancestors, collecting this fruit in the coastal tablelands forests and latter commercializing it in the local markets. This research uses the methodology of oral history and visual anthropology with presentation of collected images on board. It is intended to emphasize the botanical and environmental aspects of the Mangabeira plant, its ecosystem, territorial, economic and historical aspects of it, also the knowledge of this extractive practice of our immaterial culture.

Escafandristas do tempo: narrativas de vida e regeneração da memória em São Rafael-RN

In the late 1970s, the semi-arid region of Rio Grande do Norte was the setting of Projeto Baixo-Açu whose highlight was the building of the dam Eng. Armando Ribeiro Gonçalves, designed to collect 2.4 billion cubic meters of water. Presumably, such an initiative would bring economic and social development for thousands of potiguares who suffered the hardships of drought. However, the dam would reach several cities in the region, reaching to cover one of them: São Rafael. As a result, the early years of the 1980s, nearby, a new town was built by DNOCS. This thesis aims to discuss how the population of São Rafael recalls this fact and reconstructs its history by speaking, writing and computing, after three decades. Based on the prospect moriniana method as a strategy, visits were made to the city of São Rafael and open interviews (individual and collective) with two groups of subjects: one composed of those who lived in their ancient homeland, and another, with young people who were born in the new city. Besides the reports of these subjects, they were observed the visual narratives presented by images, mostly photographic, available on a profile created for the city in the orkut social network. As sources for this study, they were also considered the dialogues between rafaelenses accessing the above profile. Having as a central observation by Edgar Morin about what does not regenerate, degenerates . This study is the central argument that the idea of orkut has performed, today, a dual and interdependent role: being a tool that promotes a collective intelligence through cooperation, exchange of ideas and reconstitution of visual and written narratives. Far from a frozen conception in a historical perspective, it has defended the thesis that orkut has regenerated, repaired, reproduced, restored, reorganized and renewed the memory and history of a city that has succumbed to the immensity of the waters of a dam for almost thirty years
