The present study characterizes the physical environment for its fragility and its capacity to support, through geological and geomorphological properties in the study area, concerning primarily with a sustainable environmental planning for the construction and maintenance of buried linear works. The study area is located on a portion of the Paraiba Valley, which is between the latitudes 22 °30' S and 23°00' S and longitudes 44°30' W and 45° 15' W, between cities of Aparecida (SP) and Queluz (SP). The methodology was based in the visual interpretation of TM/Landsat-7 images, using as a criterion the element textural image and its way of organizing space. To do so, it was set five levels of textural density, enabling thus to the partitioning of the area in areas counterparts (Z.H.s). As a result, it was identified 133 Z.H.s. By using the same criterion textural image the following physical properties were classified: Erosion Resistance, Permeability, Plasticity X Brittle, Tropia and Relief Asymmetry for each zone counterpart, and then grouped themselves as they hold all properties equal in Units Geoenvironmental (U.G.s). As a result it was identified 18 U.G.s. The work presents, as a final result, a thematic map with favorable or restrictable sectores to the design of buried linear works. Based on this map, it can be propose traces to buried linear works, analyzing their suitability to the physical environment and reducing the impacts caused to the environment.

O Diabetes mellitus é um problema de saúde pública mundial. Tal doença é caracterizada pela redução da secreção (Diabetes mellitus tipo1) ou da ação (Diabetes mellitus tipo2) da insulina, acarretando hiperglicemia, além de alterações no metabolismo das proteínas e dos lipídeos. As consequências para o organismo são variadas, incluindo hipertensão, nefropatias, retinopatias e cardiopatias. Atualmente existe grande interesse nas ervas medicinais, como hipoglicemiantes naturais, entre elas, a spirulina. A spirulina parece ser boa fonte protéica para a alimentação, tem boa aceitação e não apresenta efeitos tóxicos aparentes. Além disso, ela pode exercer efeitos benéficos no tratamento de algumas doenças como câncer, desnutrição, obesidade, hipercolesterolemia, hipertensão arterial, diabetes mellitus,entre outras. Tendo em vista a grande possibilidade utilizar a spirulina na dieta, o presente estudo visa analisar o metabolismo muscular da glicose em ratos diabéticos. Não foram encontradas diferenças significativas entre os grupos nas variáveis metabólicas estudadas

A utilização de extratos vegetais tem sido considerada uma forte tendência no desenvolvimento de formulações dermocosméticas, uma vez que podem apresentar diversas ações, como antioxidantes e despigmentantes, atuando tanto contra os processos de envelhecimento como hiperpigmentação da pele. Dentre as plantas que apresentam tais propriedades, o chá verde se destaca devido a sua riqueza em compostos polifenólicos e taninos condensados. O extrato seco de chá verde obtido através da extração com uma solução de acetona 70% apresenta o maior teor de fenólicos e flavonoides, mas pouca diferença quando comparado com o obtido de uma solução de acetona 50%. A alta concentração desses compostos no extrato seco é responsável pela ótima ação antioxidante do chá verde, tornando-o capaz de inibir 50% dos radicais livres do meio com apenas 4,62 µg/mL quando em solução metanólica. Entretanto, a sua atividade despigmentante não se torna evidenciada, com apenas 1,93% de ação com a mesma concentração de chá verde. Este extrato seco, quando incorporado a sistemas nanoestruturados como os sistemas líquido-cristalinos estabilizados com Procetyl AWS® passa a ter uma ação antioxidante potencializada, alcançando uma inibição de radicais livres em até, aproximadamente, 72%, enquanto sua capacidade despigmentante não é demonstrada, apresentando uma inibição de tirosinase de, no máximo, 0,88%. A caracterização estrutural foi realizada por meio de análises de microscopia de luz polarizada, comportamento reológico e perfil de textura das formulações. Para o estudo de estabilidade foram empregadas avaliação visual, centrifugação e pH. A atividade antioxidante foi determinada com base na ação seqüestrante do radical 2,2-difenil-1-picril-hidrazila (DPPH) e a ação despigmentante in vitro, avaliada quanto à inibição da tirosinase, pelo método enzimático...

Introduction: The elderly population has increased, and the aging process is responsible for physical and metabolic changes in the body. For the elderly remain independent, with a better quality of life, preventing and treating diseases responsible for this increased of mortality should remain physically active. Objective: To investigate the influence of two types of exercise intervention on physical fitness and physical activity levels in older practitioners of Rio Claro-SP. Method: The study included 18 older adults with mean age 65.8 years (± 2.88) divided into two groups, Program in Physical Exercises Health Unit (PEFUS, n = 9) and Adapted Volleyball (n = 9). Classes of PEFUS were held twice a week lasting 60 min with strength, aerobic endurance, agility, coordination and balance exercises. Classes of Volleyball Adapted were performed 2 times per week lasting 120 minutes, divided into volleyball fundamental exercises and game. For evaluation of physical skills (strength, agility, coordination and flexibility), was performed the AAHPERD test battery. All participants were assessed at the baseline and after 3 months of interventions. The statistical analysis used was the repeated measures ANOVA, through the SPSS version 17.0 and significance level p <0.05. Result: After the interventions there was an increase of leisure time from 362.2 ± 214.9 min / week and 16.7 ± 28.3 min / week to 541.7 ± 137.2 and 44.4 ± 44.8 min / week to Adapted Volleyball and PEFUS, respectively. The variable coordination showed significant improvements after the interventions, decreasing from 12.1 ± 0.7 to 10.8 ± 0.5 sec for Volleyball Adapted and from 14.8 ± 0.9 to 12.1 ± 0, 9 sec for PEFUS (p <0.05). For the variable strength it was observed a group-moment interaction (p <0.05). Conclusion: The interventions showed positive results... (Complete abstract click electronic access below)

The present study was concerned with checking the water quality, the recovery of the riparian vegetation and vegetation around the springhead of stream Bandeirantes, such as the inadequate disposal of waste along this stream, which is located in Rio Claro, SP, in the period from March to July of 2010. Aiming to propose mitigation measures to reverse the degradation processes and develop activities to help a better awareness of the population directly related to this water resource. The water quality was analyzed by performing monthly sampling in three different points along the stream. The first point of sampling is in the spring of the stream, the second at the region called estradão and the third near its mouth, when it flows into the Ribeirão Claro, a tributary of the right bank of the Corumbataí river. It was calculated from the Water Quality Index (WQI) developed by Cetesb. The results were compared with current law. The riparian vegetation, which is responsible for the protection of rivers and streams, was observed and examined during the field work. The results indicated the stream as class 2 and the WQI has been classified, in the most of the analysis, such as a water of good quality. However, some parameters showed a worrying situation and highlighted the current situation, with waste deposits, furniture and animal waste into the pit of the stream studied

Nowadays the regular practice of sports is known as a way to obtain a better quality of life. On the other hand, the media has been distorting this idea, determining the ideal body as the hypertrophy phenotype. It is well known that the genetic factor does not allow all individuals to have this body shape. Besides the fact that, the anxiety of these people in obtain quick results, as one of the globalization’s consequence, make use of anabolic steroid to achieve this goal. However the bodybuilding or the strength muscle gain, make anabolic steroids users abuse and in major cases the users do not know the side effects. In front of these considerations, the present study evaluated the effects of the treatment with anabolic steroids and/or high intensity physical training on the corporal developing, the reproductive organs, bone parameters (strength and bone deformation) and seminal parameters as well the social behavior (aggressiveness). In other to obtain the experimental group, male Wistar rats were used, with 75 days old. The groups were divided into: Vehicle Non-Training (NV), Anabolic Steroid-Non-Training (NA), Vehicle-Training (TV) and Anabolic Steroid-Training (TA). These rats received i.m. injections, twice a week, of anabolic steroid (5mg/kg per animal of nandrolona decanoate) or vehicle (the same volume of peanut oil per animal) and the group TV and TA were submitted to physical training three times per week, during eight weeks. The body mass, wet weight of reproductive organs, femur and semen of the different groups were measured. The aggressive test was also realized in two steps: the first, within 4 weeks of the treatment and the other step in the end of the treatment, in this period the animal was isolated. It was not observed alterations in body mass of the groups. Though it was observed a benefic effect on the maximum strength of the... (Complete abstract click electronic access below)

No período da menopausa, a incidência de doenças cardiovasculares em mulheres é equivalente a dos homens, e assim os gastos públicos com saúde nesta população em particular, aumentam significativamente, uma vez que as mulheres possuem maior longevidade se comparadas aos homens. Os mecanismos celulares e/ou moleculares pelos quais ocorre maior incidência de hipertensão arterial em mulheres após a menopausa ainda não são claros. Uma variedade de fatores parece contribuir para a elevação de pressão arterial na menopausa, entre eles destacam-se a deficiência de estrogênio, o aumento do estresse oxidativo, a disfunção endotelial, a elevação da atividade do sistema renina-angiotensina, a elevação nos níveis plasmáticos de testosterona, as alterações no perfil lipídico e o aumento no ganho de peso. Trabalhos prévios mostram que os efeitos benéficos do exercício físico sobre o sistema cardiovascular estão relacionados a maior produção de óxido nítrico e/ou sua biodisponibilidade para o músculo liso vascular. Este último mecanismo tem sido relacionado com elevação da atividade da enzima antioxidante superóxido dismutase (SOD), que representa um importante mecanismo de defesa celular contra a formação de radicais livres. Objetivo: avaliar os níveis plasmáticos da enzima superóxido dismutase em resposta a um programa de treinamento físico aeróbio por 8 semanas realizado em mulheres no climatério. Métodos: A amostra foi constituída por 31 mulheres normotensas (49,3±1,2 anos) e 15 hipertensas (52,2±1,6 anos) todas diagnosticadas no período do climatério e sedentárias...
