Abstract: highly active antiretroviral therapy (haart) has led to a substantial increase in the survival of people living with aids, despite heterogeneities among individuals from different socioeconomic strata. the present paper analyzes aids deaths in brazil during a period in which haart became a key treatment regimen, exploring the hypothesis that "race or color" defines one dimension of socioeconomic inequality in brazil. aids mortality, stratified by gender and "race or color", was calculated using data from the national mortality system. the rates were highest among individuals classified as "black" and lower among those classified as "mixed-race", with a continuous increase among the later from 1999 to 2004 for men and women. among individuals classified as "white", mortality rates remained stable among men, but not women. median age at death among "mixed-race" individuals was lower for both men and women. differential trends according to gender and "race or color" were highlighted by the present study, indicating the pressing need to further explore the underlying factors that might explain different mortality rates in a context of universal access.

Abstract: The transverse energy distributions ($E_{T}$) have been measured for Au + Au collisions at $\sqrt{s_{NN}} = 62.4$ GeV by the STAR experiment at RHIC. They have been obtained from two measurements, the hadronic transverse energy ($E_{T}^{had}$) and the electromagnetic transverse energy($E_{T}^{em}$). $E_{T}^{had}$ has been measured from the tracks obtained by Time Projection Chamber (TPC) excluding the electrons and positrons. $E_{T}^{em}$ has been obtained by the STAR Barrel Electromagetic Calorimeter (BEMC) which measures the energy of electrons, positrons and photons. The measure of transverse energy gives an estimate of the energy density of the fireball produced in heavy ion collisions. $E_{T}$ per participant pair gives information about the production mechanism of particles.

Abstract: O uso e a ocupa o das terras devem ser planejados de forma racional a fim de evitar impactos ambientais negativos nos recursos naturais, particularmente em áreas ambientalmente protegidas por lei. O objetivo deste trabalho foi avaliar atributos de qualidade dos solos em áreas de preserva o permanente da Microbacia do Ribeir o do Gama, Distrito Federal, Brasil, para verificar o efeito do uso antrópico. Foram avaliados atributos físicos, químicos e biológicos de qualidade de organossolos em cinco áreas de uso e ocupa o diversificada das terras: três áreas cultivadas (hortali as, eucalipto e mandioca) e duas áreas preservadas (pastagem nativa e mata de galeria). As amostras de solo foram coletadas nas camadas de 0-10 e 10-20 cm. Os dados obtidos pelas análises físicas, químicas e biológicas dos solos foram avaliados estatisticamente por meio do software Sisvar 4.6. Os resultados obtidos mostraram influência dos usos e ocupa es diferentes das terras em rela o aos atributos de qualidade dos solos. O manejo dos solos adotado nessas áreas foi considerado o principal fator de altera o dos atributos físicos, químicos e biológicos, destacando-se a compacta o dos solos sob áreas de vegeta o nativa e diminui o da matéria organica nos solos em sistemas cultivados. The use and occupation of soil should be planned in a rational way to avoid negative environmental impacts on natural resources, particularly in areas environmentally protected by law. This study aimed to evaluate quality attributes of soil in permanent preservation areas of a Ribeir o do Gama Watershed, Distrito Federal, Brazil, to verify the influence of anthropic use. The physical, chemical and biological attributes of Histosol quality were assessed in five areas of diversified use and soil occupation: three areas under cultivation (vegetables, eucalyptus and cassava) and two preserved areas (native pasture and gallery forest). Soil samples were collected in 0-10 and 10-20 cm depth. The data obtained for physical, chemical and biological analysis of the soils were statistically evaluated using the Sisvar 4.6 software. The results obtained showed the influence of different uses and soil occupation in relation to the attributes of soil quality. The adopted management in these areas was considered the main factor of change in the physical, chemical and biological attributes, highlighting the compaction of soils under native vegetation and decrease of organic matter in the soils under cultivated systems.

Open Journal of Animal Sciences (OJAS) , 2013, DOI: 10.4236/ojas.2013.31003
Abstract: This study aimed to analyze the possible metabolic disturbances caused by creatine supplementation on aerobic capacity of rats, inferred by the maximal lactate steady state. Forty male Wistar rats (90 days old) were distributed into two groups for eight weeks: trained group (T): rats that were submitted to a training protocol, and supplemented-trained group (TCr): rats that were submitted to a training protocol and received balanced diet supplemented with 2% creatine. The blood lactate concentrations equivalent to maximal lactate steady state during treadmill running were analyzed at the beginning and also at the end of the experiment. At the end of the experiment were done comparing the test results MLSS between the two groups. At the beginning of the experiment, prior to groups division, the majority of animals obtained MLSS at a speed of26 m/min, blood lactate concentration of 3.79 ± 0.76 mmol/L. At the end of the experiment, most of trained rats in T presented MLSS at the speed of28 m/min, blood lactate concentration of 3.37 ± 0.68 mmol/L. Most TCr had MLSS at the speed of28 m/min, blood lactate concentration of 3.52 ± 0.69 mmol/L. We conclude that creatine supplementation was not the cause of the improvement in the aerobic capacity of rats in the tread-mill exercise.

Abstract: Therefore, the aim of the present study was to assess the effects of two non-isocaloric diets (commercial Purina? and AIN-93M), which are considered standard diets, on the accumulation of fat in the liver of rats when offered ad libitum or in a restricted amount.Thus, 40 Wistar rats (90 days old) were separated into 4 groups according to the amount of food offered (ad libitum or dietary restriction) and the type of diet (commercial diet, 3,028.0 kcal/g or AIN-93M, 3,802.7 kcal/g): animals fed the commercial Purina? diet ad libitum (AP), animals fed restricted amounts of the commercial Purina? diet (RP), animals fed the AIN-93M diet ad libitum (AD), and animals fed restricted amounts of the AIN-93M diet (RD). Dietary restriction consisted of pair-feeding the RP and RD groups with 60% of the total food consumed by the corresponding ad libitum groups.Because of its higher carbohydrate and calorie content, AIN-93M was found to accelerate weight gain, reduce glucose tolerance and peripheral insulin sensitivity, and increase the amount of fat in the liver when compared to the commercial diet. Conversely, a 40% dietary restriction assisted in weight loss without causing malnutrition, contributing to an improved glucose tolerance and higher levels of HDL cholesterol.Therefore, differences in the amount of carbohydrates and calories provided by the diet can lead to important metabolic disorders, such as impaired tolerance and accumulation of hepatic fat, and dietary restriction improves serum and tissue lipid profiles in laboratory animals.Non-alcoholic fatty liver disease (NAFLD) is characterised by the presence of fat droplets in the liver [1,2]. Lipid levels equal to or greater than 5% of an organ's weight [1,3] characterises steatosis, which may range from simple fat accumulation without any evidence of inflammation to necroinflammatory manifestations, including steatohepatitis. Steatohepatitis, in turn, may progress to fibrosis in 50% of cases, to cirrhosis in 15% of ca
