Abstract: the accomplishment of the transit social function goes necessarily through the fulfillment of its participants' demands of accessibility, mobility and quality of life. mobility includes the ease of people and properties movement in the city in terms of the complex activities carried out, composing a component of the quality of life wanted by its residents. problems in infrastructure and transportation quality compromise the mobility. accessibility constitutes the ease, related to distance, time and cost, in reaching the desired destination, comprehending the effectiveness of the transport system as connecting separated locations. it reflects a relationship between people and space directly related to the citizens' quality of life. talking about quality of life in traffic necessarily needs to investigate the transport system of cities, especially the collective, in order to discuss its influence on the configuration of urban design, and the consequent impact on the accessibility and mobility of social actors

Abstract: Background Wound healing is impaired in diabetes mellitus, but the mechanisms involved in this process are virtually unknown. Proteins belonging to the insulin signaling pathway respond to insulin in the skin of rats. Objective The purpose of this study was to investigate the regulation of the insulin signaling pathway in wound healing and skin repair of normal and diabetic rats, and, in parallel, the effect of a topical insulin cream on wound healing and on the activation of this pathway. Research Design and Methods We investigated insulin signaling by immunoblotting during wound healing of control and diabetic animals with or without topical insulin. Diabetic patients with ulcers were randomized to receive topical insulin or placebo in a prospective, double-blind and placebo-controlled, randomized clinical trial (NCT 01295177) of wound healing. Results and Conclusions Expression of IR, IRS-1, IRS-2, SHC, ERK, and AKT are increased in the tissue of healing wounds compared to intact skin, suggesting that the insulin signaling pathway may have an important role in this process. These pathways were attenuated in the wounded skin of diabetic rats, in parallel with an increase in the time of complete wound healing. Upon topical application of insulin cream, the wound healing time of diabetic animals was normalized, followed by a reversal of defective insulin signal transduction. In addition, the treatment also increased expression of other proteins, such as eNOS (also in bone marrow), VEGF, and SDF-1α in wounded skin. In diabetic patients, topical insulin cream markedly improved wound healing, representing an attractive and cost-free method for treating this devastating complication of diabetes.

Abstract: organic matter may be considered an important soil quality indicator, as it is related with many soil chemical, physical, and biological characteristics. the study of total organic carbon (toc) of the soil and its fractions is important. this study was conducted in a micro basin, with the purpose of: analyzing characteristics and quantify the stocks of total organic carbon (toc) and its fractions as evidence of soil quality after different forms of use: (1) atlantic forest, (2) cocoa (theobroma cacao), and (3) pasture (brachiaria decumbens). samples were collected for each use type (at 0-10 and 10-20 cm). the chemical and physical soil properties were characterized and the chemical and physical fractions of organic carbon determined. it was observed that the organic carbon levels did not differ in the two depths analyzed, even under different use types. the percentage of humified carbon in the fulvic acid and humin fractions was higher in the 0-10 cm layer under pasture and the percentage of non-humified carbon was lower under cocoa and pasture. there was a higher c:n ratio in the 10-20 cm layer of the soil under pasture. cocoa acao increased the level of organic carbon in the light fraction in the 10-20 cm layer. the substitution of the native forest by cocoa and pasture resulted led to no significant changes in the cot concentration and organic matter fractions in the studied area.

Ciência e Tecnologia de Alimentos , 2003, DOI: 10.1590/S0101-20612003000100003
Abstract: in this work, it was verified the influence of the consumption of biomass from different origins on the body weight gain and food consumption by adult male wistar rats. groups fed the biomasses in the levels of 5% or 10% (w/w) were compared with a control. biomass i did not promote significant differences in food consumption or body weight. biomass ii did not cause significant difference in the body weight, but it caused an increase in food consumption. biomass iii did not cause significant differences in food consumption or body weight, but there was a tendency of increasing body weight for the 10% spirulina group. the hypothesis that different biomasses may have different properties was confirmed, but not the claim that spirulina may decrease body weight or food consumption.

Ciência e Tecnologia de Alimentos , 2003,
Abstract: Neste trabalho verificou-se a influência do consumo de biomassas provenientes de três diferentes origens sobre o peso corporal e consumo de ra o em ratos Wistar, machos e adultos. Grupos que consumiram 5% ou 10% (p/p) da biomassa foram comparados com um controle. A biomassa I n o promoveu diferen a significativa no consumo de ra o ou peso corporal dos três grupos. A biomassa II n o causou diferen a significativa no peso corporal, mas sim no consumo de ra o. A biomassa III n o causou diferen a significativa no consumo de ra o, nem no peso corporal, mas houve tendência de maior ganho de peso para o grupo que consumiu a ra o contendo 10% de spirulina. Os resultados obtidos indicam que diferentes biomassas podem apresentar diferentes propriedades, mas n o confirmam a alega o de que a spirulina pode levar a diminui o de peso ou de consumo de alimento.
