ABSTRACT
OBJETIVO: avaliar a relação entre a violência e a qualidade de vida de mulheres isoladas socialmente em decorrência da COVID-19. MÉTODO: estudo transversal, quantitativo, desenvolvido em Campina Grande PB, Brasil. A amostra constituiu-se de mulheres maiores de 18 anos, em isolamento social pela COVID-19. Utilizaram-se três instrumentos para coleta de dados, estes analisados por meio de estatística descritiva e inferencial, sendo adotado significância p<0,05. RESULTADOS: houve predominância de mulheres com baixa qualidade de vida (53,1%) e vítimas de violência psicológica (61,1%). A relação da violência física, psicológica e geral apresentou significância estatística entre todos os domínios de qualidade de vida nos testes de correlação de Spearman (p<0,05) e de comparação de Mann Whitney (p<0,05). CONCLUSÃO: o desfecho da violência física e psicológica relaciona-se de forma negativa nos aspectos físicos, psicológicos, relações sociais e meio ambiente da qualidade de vida de mulheres isoladas socialmente em decorrência da COVID-19.
OBJECTIVE: to assess the relationship between violence and the quality of life of women socially isolated due to COVID-19. METHOD: a cross-sectional, quantitative study was developed in Campina Grande PB, Brazil. The sample comprised women over 18 years in social isolation due to COVID-19. Three instruments were used for data collection, and descriptive and inferential analyses were carried out, with a significance of p<0.05. RESULTS: there was a predominance of women with low quality of life (53.1%) and victims of psychological violence (61.1%). The relationship between physical, psychological, and general violence achieved statistical significance in all quality of life domains in the Spearman correlation test (p<0.05) and the Mann-Whitney test (p<0.05). CONCLUSION: the outcome of physical and psychological violence is negatively related to the physical, psychological, social relationships, and environmental aspects of the quality of life of women socially isolated due to COVID-19.

Grape, orange, peach and passion fruit nectars were formulated and adulterated by dilution with syrup, apple and cashew juices at 10 levels for each adulterant. Attenuated total reflectance Fourier transform mid infrared (ATR-FTIR) spectra were obtained. Partial least squares (PLS) multivariate calibration models allied to different variable selection methods, such as interval partial least squares (iPLS), ordered predictors selection (OPS) and genetic algorithm (GA), were used to quantify the main fruits. PLS improved by iPLS-OPS variable selection showed the highest predictive capacity to quantify the main fruit contents. The selected variables in the final models varied from 72 to 100; the root mean square errors of prediction were estimated from 0.5 to 2.6%; the correlation coefficients of prediction ranged from 0.948 to 0.990; and, the mean relative errors of prediction varied from 3.0 to 6.7%. All of the developed models were validated.

Different factors may contribute to the development of neurodegenerative diseases. Among them, metabolic syndrome (MS), which has reached epidemic proportions, has emerged as a potential element that may be involved in neurodegeneration. Furthermore, studies have shown the importance of the sirtuin family in neuronal survival and MS, which opens the possibility of new pharmacological targets. This study investigates the influence of sirtuin metabolic pathways by examining the functional capacities of glucose-induced obesity in an excitotoxic state induced by a quinolinic acid (QA) animal model. Mice were divided into two groups that received different diets for 8 weeks: one group received a regular diet, and the other group received a high-fat diet (HF) to induce MS. The animals were submitted to a stereotaxic surgery and subdivided into four groups: Standard (ST), Standard-QA (ST-QA), HF and HF-QA. The QA groups were given a 250 nL quinolinic acid injection in the right striatum and PBS was injected in the other groups. Obese mice presented with a weight gain of 40 % more than the ST group beyond acquiring an insulin resistance. QA induced motor impairment and neurodegeneration in both ST-QA and HF-QA, although no difference was observed between these groups. The HF-QA group showed a reduction in adiposity when compared with the groups that received PBS. Therefore, the HF-QA group demonstrated a commitment-dependent metabolic pathway. The results suggest that an obesogenic diet does not aggravate the neurodegeneration induced by QA. However, the excitotoxicity induced by QA promotes a sirtuin pathway impairment that contributes to metabolic changes.

RESUMOAs praças públicas de Porto Alegre, na segunda metade da década de 1920, receberam melhorias na sua infraestrutura visando oportunizar a prática esportiva. Como ocorreu a difusão das práticas esportivas nas praças de Porto Alegre no período compreendido entre as décadas de 1920 a 1940 é a questão central deste estudo. A análise documental de fontes impressas revelou que a implantação do Serviço de Recreação Pública (SRP) em 1926, foi fundamental para a ocupação das praças, enquanto espaços destinados às práticas esportivas. Para além da prática foram potencializadas competições esportivas nas praças, resultando na formação dos clubs, nas décadas de 1930 e 1940.
ABSTRACTThe Public squares of Porto Alegre, in the second half of the 1920s, received improvements in infrastructure to create opportunities for practice sports. How did the spread of sports activities in the squares of Porto Alegre in the period between the decades from 1920 to 1940 is the central question of this study. The documentary analysis of printed sources revealed that the implementation of the Public Service Recreation (SRP) in 1926, was essential in the occupation of squares as spaces intended for sports practices. In addition to the practice were potentiated sports competitions in the squares, resulting in the formation of clubs in the decades 1930 and 1940.
ABSTRACT
As apresentações públicas de diversos exercícios físicos e bailados, denominados de "demonstrações de Educação Física" foram realizadas no parque Farroupilha na cidade de Porto Alegre, no mês de setembro, na chamada "Semana da Pátria", em comemoração a Independência do Brasil. Identificar como ocorreram as Demonstrações de Educação Física no parque Farroupilha em Porto Alegre, nas décadas de 1930 e 1940 é o objetivo central deste estudo. A análise documental revelou que tais práticas culturais foram potencializadas como veículo de difusão do nacionalismo no período do Estado Novo, produzindo representações de uma identidade nacional.

ABSTRACT
As praças se afirmaram enquanto espaços de sociabilidade e lazer dos porto-alegrenses a partir de meados dos anos 1920. O objetivo deste estudo é identificar como ocorreu a emergência e difusão das práticas corporais e esportivas nas praças de Porto Alegre nas décadas de 1920 a 1940, e que representações de identidades culturais foram construídas. A análise documental das fontes revelou que a utilização das praças foi privilegiada no que diz respeito à promoção de práticas corporais e esportivas. As denominadas praças de desportos se constituíram em espaços para as práticas organizadas dirigidas pelo Serviço de Recreação Pública (SRP) instaurado em 1926. Na transição das décadas de 1930-1940, as competições esportivas foram potencializadas nas praças constituindo-se em um espaço de produção de representações de identidades.

The objective of this study is to identify how it has occurred corporal and sportives practices emergency and diffusion in Porto Alegre city squares betwenn 1920 and 1940 decades, and which identities representations had been constructed. The documentary analysis of the sources disclosed that squares use was privileged for corporal and sportives practices promotion. The called Squares of Sports had been constituted in spaces for organized pratices directed by the Public Recreation Service (PRS), introduced in 1926. In the transistion of 1930-1940 decades, the sportives competitions had been potentiated in the squares consisting it as space of identities representations production.
