Revista Katálysis , 2013,
Abstract: Este ensaio tem como objetivo discutir premissas de análise da temática movimentos sociais e transforma o societária presentes na formula o marxista. Para tanto, retoma o pensamento de autores clássicos, em especial, Lênin, Rosa Luxemburgo e Gramsci. Destaca, com base nesses autores, as determina es fundamentais para a análise das lutas sociais da classe trabalhadora, enfatizando a teoria da organiza o, a ampla participa o das massas e a constru o de uma nova hegemonia. The purpose of this essay is to discuss the premises of the analysis of the theme social movements and social transformation found in the Marxist formulation. To do so, it looks at the work of classic authors, particularly Lenin, Rosa Luxemburg and Gramsci. It highlights, based on these authors, the determinations fundamental to the analysis of the social struggles of the working class, emphasizing the theory of organization, the broad participation of the masses and the construction of a new hegemony.

Abstract: RESUMO Avaliaram-se o pH e a concentra o de am nia ruminal (N-amoniacal), a taxa de passagem, o balan o de compostos nitrogenados e a produ o de proteína microbiana em novilhos Holandês x Zebu alimentados com dietas contendo quatro níveis de proteína bruta (10,5; 12; 13,5 e 15%), com base na matéria seca. As dietas foram constituídas de 65% de feno de capim-tifton 85 e 35% de concentrado. Foram utilizados quatro bovinos castrados fistulados no rúmen e abomaso, com peso vivo médio inicial de 487,3 kg, distribuídos em um quadrado latino 4 x 4. Cada período experimental teve dura o de 20 dias: dez para adapta o às dietas e dez para coletas. O pH e N-amoniacal foram mensurados no fluido ruminal imediatamente antes e 2, 4, 6 e 8 horas, após o fornecimento da dieta. A taxa de passagem foi determinada pelo modelo unicompartimental, utilizando-se óxido de cromo como indicador. Para determina o da produ o de proteína microbiana, utilizaram-se as bases purinas (RNA) no abomaso como indicador microbiano. A concentra o de am nia e o pH ruminal foram influenciados pelos tempos de coleta, estimando-se valores máximos de 17,43 e 6,54 mg/dL, às 3,62 e 4,17 horas após a alimenta o, respectivamente. A taxa de passagem da digesta n o foi afetada pelas dietas, registrando-se valor médio de 3,69%/h. Os fluxos de compostos nitrogenados no abomaso e a eficiência de síntese microbiana também n o foram afetados pelos níveis de proteína bruta das dietas, ao passo que o balan o de nitrogênio, expresso em g/dia, aumentou linearmente com o incremento de proteína bruta.

Abstract: the objective of this trial was to study the effects of different dietary levels of crude protein (cp) on intake and apparent total tract, intestinal, and ruminal digestibilities of nutrients in holstein x zebu steers. the diets contained [dry matter (dm) basis]: 10.5, 12, 13.5, or 15% of cp and a forage (tifton 85):concentrate ratio of 65:35. four castrated animals averaging 487.3 kg of body weight at the beginning of the trial and fitted with both abomasum and rumen cannulas were randomly assigned to a 4 x 4 latin square. each experimental period lasted 20 days with 10 days for diet adaptation and 10 days for sample collection (feces, abomasum digesta, ruminal content, and urine). chromium oxide was used as the external marker for determination of fecal excretion. increasing dietary levels of cp did not change significantly the intakes of dry matter (dm), organic matter (om), neutral detergent fiber (ndf), and total digestible nutrients (tdn). however, intake of cp increased while that of ether extract (ee) and non-fiber carbohydrate (nfc) decreased with the increment of dietary cp. apparent total tract digestibilities of dm, om, and cp all increased linearly by increasing the dietary cp from 10.5 to 15%. except for intestinal digestibility of cp that increased 2.77 percentage units for each 1% increment in the diet cp, the different dietary cp levels did not affect intestinal and ruminal digestibilities of all remaining nutrients in the current trial.

Abstract: American tegumentary leishmaniasis (ATL) in Brazil is mostly caused by Leishmania (Viannia) braziliensis, with known forms of the disease being cutaneous (CL), mucosal (ML) and disseminated (DL) leishmaniasis. The development of the lesion in ATL is related both to the persistence of the Leishmania in the skin and to the parasite-triggered immune and inflammatory responses that ensue lesions. In this context one factor with expected role in the pathogenesis is insulin-like growth factor (IGF)-I with known effects on parasite growth and healing and inflammatory processes. In the present study, we addressed the effect of IGF-I on intracellular amastigote isolates from CL, ML and DL patients within human macrophage and we evaluated the IGF-I and IGF-binding protein-3 (IGFBP3) serum levels in patients presenting different clinical forms and controls from the endemic area

Abstract: O conhecimento, a informa o e a comunica o foram o paradigma da estrutura e do funcionamento das sociedades atuais. Tomando por base a pressuposto de que o conhecimento é sempre contextualiza o pelas condi es que o tornam possível, e que ele só progride na medida em que transforma essas mesmas condi es, estudam-se os movimentos sociais e as entidades representativas da sociedade, como as organiza es n o-governamentais, enquanto espa os de produ o, organiza o e inova o de conhecimentos. Cenários de disputas simbólicas onde se confrontam matrizes cognitivas e políticas diferenciadas, nesses espa os formam-se a cada vez, múltiplas configura es de comunica o e informa o, que apontam para novas formas de organizar os conhecimentos na sociedade, com sentido emancipatório. A idéia de terceiro conhecimento é construída para estudar as redes de produ o de sentidos assim constituídas.
