Treinamento aer��bio de nata����o aumenta a atividade de enzimas antioxidantes e o conte��do de glicog��nio no musculoesquel��tico de ratos

INTRODUCTION: Studies which verified the effects of physical exercise on oxidative stress biomarkers and its relation to muscle glycogen are lack. OBJECTIVE: The present study verified the effects of aerobic swimming training (AST) on biomarkers of oxidative stress, glycogen content and cell growth in the skeletal muscle of rats. METHODS: Eighteen male Wistar rats (60 days) were divided into two groups: Sedentary Group (SG; n = 10): sedentary rats; and Trained Group (TG; n = 8): rats subjected to AST (5.0% of body weight), 1h/day, 5x/week, during 8 weeks. The activity of antioxidant enzymes (AOE) superoxide dismutase (SOD; U/ml), catalase (CAT; ��mol/min/100mg), glutathione peroxidase (GPx; nmol/min/100mg), and substances that react with thiobarbituric acid levels (TBARs; nmolMDA/mg protein) were determined in the right gastrocnemius muscle. Glycogen (mg/100mg), protein (g/100g), and DNA (g/100g) contents were evaluated in the left gastrocnemius muscle. Data were analyzed by Student t-test (p < 0.05). RESULTS: AOE activity was higher in the TG group (CAT: 0.87 �� 0.04; SOD: 6.49 �� 0.45; GPX: 6.49 �� 0.52) when compared to SG group (CAT: 0.52 �� 0.03; SOD: 4.10 �� 0.37; GPx: 2.87 �� 0.35). TBARs levels was lower in TG (TG: 2.35 �� 0.45; SG: 8.90 �� 0.47). Gastrocnemius glycogen content (SG: 0.108 �� 0.013; TG: 0.320 �� 0.012) and protein/DNA ratio (SG: 24.94 �� 3.25; TG: 41.68 �� 4.02) were higher in TG group. CONCLUSION: Altogether, these data provide evidence that AST improved antioxidant defense, which may be associated to higher glycogen content of skeletal muscle of the animals.

How marine upwelling influences the distribution of Artemesia longinaris (Decapoda: Penaeoidea)?

Upwelling events can occur in most of the oceans altering the water physical, chemical and sediment conditions and consequently the species communities dwelling the areas. For better understanding the behavior of populations inhabiting upwelling regions, the spatial and temporal distribution of a Penaeoidea shrimp was studied correlating it with the abiotic factors that vary during upwelling and non-upwelling periods in an area under influence of Cabo Frio upwelling. Bottom salinity and temperature, organic matter and sediment type from each station were sampled from March 2008 to February 2010, in six stations located between 5 and 45 m depth. The lowest temperatures were recorded during spring and summer for both years with temperature values lower than 19 degrees C. A total of 26,466 Artemesia longinaris shrimps were captured mainly in 10-35 m depth. Upwelling periods showed significant differences in abundance in relation to non-upwelling periods. The spatial distribution among stations varied according to the temperature with higher abundance in stations with values between 19 and 21 degrees C. The highest abundance of A. longinaris was recorded in spring and summer when intrusions of the cold waters of South Atlantic Central Waters (SACW) were frequent. Thus, the effect of cold water of SACW boosted by the upwelling was a determinant factor in the spatial and temporal distribution of A. longinaris in the studied region.

Analise t��cnico-econ��mica de um gaseificador Downdraft e de filtros para limpeza de g��s de s��ntese

The biomass gasification systems have been used for a long time and prove to be a good alternative to the generation of energy problems. This type of management requires a simple installation and maintenance which gives them a high availability. In Biomass project via Call CTEnerg 33/2006-1, funded by the Ministry of Science and Technology - MCT - Brazil, the Group Energy Systems Optimization ��� GOSE - at FEG - UNESP built and tested two prototypes of gasifiers. These is fed with 25 kg / h of dry wood (chips), and 50 Nm3 / h of air to produce gas at a flow rate of approximately 70 Nm3 / h of wood (syngas) at a temperature approximately 600 �� C. In this work of graduation, studies were conducted on the materials used in both the gasifier as well as cleaning the filter synthesis gases. The system of gas cleaning and conditioning is vital to ensure the life of the Internal Combustion Engine. In this case the studies of different filters for small gasification systems (properties, materials used, characteristics, types, etc.) are very relevant to its use in the prototype of the college campus. Were also performed a technical and economic analysis of a cogeneration system that consists in the combination of the downdraft gasifier studied in this work, an internal combustion engine, two heat exchangers and a SRA (absorption system refrigerator). Were calculated the costs of electricity generation, hot water and cold water. Finally, we analyzed the economic feasibility of the project

An��lise comparativa entre sistemas de resfriamento de inje����o de pl��stico

This study aims to prove the economic feasibility of the installation of mechanical compression chillers on plastic injection molding machines in order to reduce the production cycle time of toothbrush cables in a specific case study. This evidence was confirmed by the comparative analysis of the system replaced and the new system installed. The old system had only one closed loop cooling tower which pumped chilled water to the injection molds, and the new system has the same tower sending cold water to the condensers of individual chillers installed on each injection machine. We conducted an analysis of energy efficiency in each system, showing that in terms of thermal efficiency virtually nothing has changed, but in terms of electricity demand the new system consumes 60.3 kW more. We conducted an analysis of machine productivity for both systems, showing a much higher productivity of the new system due to reduced cycle times caused by the presence of chillers and their greater cooling capacities. Equipped with data such as electricity rates, increases in operating costs and initial investments, the increase in consumption and demand of electricity plus the cycle time reduction were also calculated over so the simple payback 1 year and 2 months was reached

Fibras naturais: caracter��sticas qu��micas e potenciais aplica����es

This study has as objective determining the chemical properties that serve as the basis for potential scientific and technological applications of seven species of fibrous plants cultivated in Brazil, which are: Banana��� (Musa spp.), ���Coco��� (Cocos nucifera), Curau�� (Ananas erectifolius), Fique (Furcraea andina), Piteira��� (Furcraea gigantea), Sisal(Agave sisalana) and ���Taboa��� (Typha domingensis). The tests for determining the percent dry completely, extractives soluble in cold water, in hot water, in sodium hydroxide 1% and in ethanol-toluene, and the percentages of ash, hydrophobicity, lignin, holocellulose and cellulose were performed at the Department of Environmental Sciences, Agronomy College (FCA) of UNESP ��� Botucatu, S��o Paulo State. It also presents a literature review about these fibers and their potential applications. Differences between the results obtained and those found by other authors are possibly explained by variations on the origin of plant material, the harvest season, the climate and soil where they were grown. However, the results and the methodology used, serve as a basis for further studies with natural fibers

Avalia����o do efeito ambiental nas propriedades mec��nicas e viscoel��sticas de comp��sitos h��bridos de tit��nio/fibra de carbono/resina ep��xi

Hybrid composites combining metal plates and laminates with continuous fiber reinforced polymer, called fiber-metal (CHMF), have been particularly attractive for aerospace applications, due mainly to their high mechanical strength and stiffness associated with low density. These laminates (CHMF) consist of a sandwich structure consisting of layers of polymer composites and metal plates, stacked alternately. This setting allows you to combine the best mechanical performance of polymer composites reinforced with long fibers, to the high toughness of metals. Environmental effects should always be considered in the design of structural components, because these materials in applications are submitted to the effects of moisture in the atmosphere, the large cyclical variations of temperature around 82 �� C to -56 �� C, and high effort mechanical. The specimens of fibermetal composite were prepared at EMBRAER with titanium plates and laminates of carbon fiber/epoxy resin. This study aims to evaluate the effect of different environmental conditions (water immersion, hygrothermal chamber and thermal shock) of laminate hybrid titanium/carbon fiber/epoxy resin. The effects of conditioning were evaluated by interlaminar shear tests - ILSS, tensile, and vibration free
