The aim of this paper is to discuss the quality of fiscal policy in Brazil and Mexico and investigate whether fiscal policy influence is favorable to reduce the unemployment rate. Public spending, which has a positive effect on the level of employment when results in additional aggregate demand, may cause a negative effect on employment, if its financing depends on persistent high interest rates. Brazil and Mexico have engaged in a long effort to control public spending and to reduce the public deficit to zero. Does this policy bring a positive result to the economic activity no matter how actual public deficit has been financed? We select variables related to public budget as public sector borrowing requirements, taxes, public debt and others to form a data base. The fiscal institutional arrangement and the data allow us to evaluate the fiscal policy as a who leand to discuss the importance of credibility and reputation of the government.

Propolis has been used in folk medicine in different regions of the world including Latin America. Propolis is a resinous mixture of substances collected by honey bees from several botanical sources, and its composition contains a rich chemical variety, depending on the geographical area and plant sources. Our aim was to compare the modulatory effect of propolis samples from three different countries of Latin America (Brazil, Cuba and Mexico) on pro- and anti-inflammatory cytokine production (tumor necrosis factor (TNF)-α and interleukin (IL)-10, respectively) by human monocytes. Cells were incubated with propolis for 18 h at 37°C. Cell viability was assessed by 3-(4,5-dimethyl-thiazol-2-yl)-2,5-diphenyltetrazolium bromide method, and cytokine production was determined by ELISA. All samples did not affect monocyte viability. Brazilian propolis stimulated both TNF-α and IL-10 production by monocytes. Cuban propolis stimulated TNF-α and inhibited IL-10 production, while Mexican sample exerted the opposite effect, inhibiting TNF-α and stimulating IL-10 production. The major compounds found in Brazilian, Cuban and Mexican propolis samples were artepillin C, isoflavonoids and pinocembrin, respectively. Brazilian, Cuban and Mexican propolis contained different components that may exert pro- and anti-inflammatory activity depending on concentration, what may provide a novel approach to the development of immunomodulatory drugs containing propolis.

A manutenção do balanço hídrico ou de água é particularmente desafiadora para os anfíbios em virtude de seu tegumento altamente permeável e o risco associado de perda evaporativa de água. Neste sentido, anuros terrestres exibem uma grande diversidade de mecanismos que atuam na diminuição da perda evaporativa de água e contribuem para a manutenção de um balanço hídrico adequado. Ademais, algumas espécies de anuros são conhecidas por tolerar altos níveis de desidratação e por engajar-se em atividades de rotina na natureza, ainda que sob níveis variáveis de desidratação. Finalmente, o próprio nível de desidratação pode acarretar alterações nos fatores envolvidos na manutenção do balanço de água dos anuros, aspecto muito pouco explorado em espécies terrestres neotropicais. Dessa forma, no presente estudo, mensuramos as taxas de perda evaporativa de água (PEA), reidratação a partir de água livre (Re) e calculamos a resistência da pele a desidratação (RP) em indivíduos adultos de Rhinella schneideri submetidos experimentalmente a diferentes níveis de desidratação (99%, 90%, 80% e 70% da massa corpórea inicial). Ademais, medimos as alterações causadas pela desidratação na osmolalidade plasmática (Osm), hematócrito (Htc), concentração de hemoglobina no sangue ([Hb]) e massa percentual dos órgãos viscerais. O objetivo central deste estudo foi avaliar os efeitos potenciais de diferentes níveis de desidratação sobre indicadores e repostas fisiológicas relevantes para a manutenção do balanço hídrico em uma espécie de anfíbio anuro terrestre. Nossos resultados mostram que quanto mais desidratados os animais, maiores a RP, a Re, a Osm, o Htc e a [Hb], e menores a PEA, e a massa percentual do fígado e do rim. O aumento da Osm, Htc e [Hb] indicam uma diminuição do compartimento aquoso do sangue, o que pode estar relacionado ao aumento da Re. A relação entre diminuição da PEA e aumento da...

The alimentation of fitness people is fundamental by health. This study it has for objective to evaluate of quali-quantitative form the proteic-caloric ingestion, the nitrogen balance and its relation caloric ingestion/estimated metabolic rate, in colleges student practicing of body-building. Eleven body-builders student (18 until 30 years old), both sex, had been analyzed. The attainment of data used an alimentary register, and the gotten information were analyzed together with the nitrogen balance from 24 hours of piss collection. We observed that the nitrogen balance of individuals that make use of some protein supplement is significantly bigger than individuals that do not consume no type of it. This because, the percentile caloric obtained from protein ingestion is significantly raised, and this associate to the caloric ingestion in this group also is raised, determines the obtained results.

This paper focuses on the process of institutionalization of public policies of Solidarity Economy in the federal government during President Lula’s first term (2003-2006). During this period, the authors analyze in particular the creation and operation of the National Secretariat for Solidarity Economy (SENAES) – a structure established under the Ministry of Labor in order to implement social inclusion policies designed to generate jobs and income. This approach allows the formulation of hypotheses about the institutional context of SENAES, its scope, limits and challenges.

Based on climatological data and energy flow, this paper analyzes the behavior observed in microclimatic an important remnant of cerrado in the São Paulo State. The seasonal climate is well marked, in the study area, with two climatic periods (one dry and one wet). The vegetation presents physiology as a function of water availability and the local thermal conditions and can be seen marked changes in the landscape due to the more or less presence of solar radiation. It’s important to understand the ecosystems behave in the context of global change. It has gained the attention of many researchers in the world.
