Obtenção e caracterização de lipossomas unilamelares pequenos contendo cafeína

Due to great difficulty of penetration of drugs through skin, different organized systems, such as liposomes, have been studied in order to increase percutaneous penetration. The aims of this work were to obtain and characterize small unilamellar liposomes containing caffeine (CAF). Liposomes composed by soy phosphatidylcholine - PS (40 mM) or hydrogenated PS - PSH (40 mM), with and without cholesterol - CHO (6 mM) and CAF (30 mg/mL), were characterized by size distribution, determination of mean diameter and encapsulation efficiency. Uniform size distribution with low polidispersity was observed. The mean of diameters obtained were: PS/CHO (64 nm), PS (80 nm), PSH/CHO (85 nm), PS/CAF (145 nm), PS/CHO/CAF (147 nm), PSH/CHO/CAF (152 nm), PSH (166 nm) and PSH/CAF (481 nm). The obtained encapsulation efficiency was 10.84% for PSH/CHO/CAF, followed by PS/CHO (6.61%), PSH/CAF (3.07%) and PS/CAF (1.57%).

In vitro ANTIGIARDIAL ACTIVITY OF THE CYSTEINE PROTEASE INHIBITOR E-64

As cisteína-proteases estão entre os alvos mais promissores para o desenvolvimento de novos agentes terapêuticos, visto que participam de eventos fundamentais do ciclo de vida de muitos microorganismos, inclusive Giardia. Como a atividade das proteases pode ser controlada por inibidores específicos, essas substâncias têm sido avaliadas quanto ao potencial antiparasitário. Diante disso, o presente estudo teve por objetivo avaliar o efeito in vitro do inibidor de cisteína-proteases E-64 sobre o crescimento, a aderência e a viabilidade de trofozoítos de cepa de Giardia isolada em Botucatu. Nos ensaios de crescimento e aderência, o número de trofozoítos foi estimado microscopicamente em hemocitômetro, enquanto que a viabilidade celular foi avaliada pelo método do MTT. No presente estudo, embora o metronidazol tenha se apresentado bastante efetivo, o E-64 mostrou ser capaz de inibir o crescimento, a aderência e a viabilidade em taxas superiores a 50%, especialmente nos cultivos expostos à concentração de 100 µM. A despeito de preliminares, esses resultados demonstram que o inibidor E-64 pode interferir em processos primordiais para a sobrevivência do parasita, além do que, abrem novas perspectivas para investigações futuras a fim de se avaliar o real potencial giardicida dos inibidores de proteases.

Partidos, sindicatos e movimentos sociais nos anos 1950-64: balanço histórico-bibliiográfico prelliminar

This text presents the first results of including research, in process, that it intends to investigate - in the period from 1950 to 1964 - the picture of the progressive political parties, the unions of the city and of the field, and the social movements marked by the national statement and for the anti-imperialism, especially those linked to the world labor perspective, discussing their proposals, differences, performances and commitments due to the political-cultural effervescence of this historical moment.

Da prescrição curricular ao currículo como ação compartilhada: dilemas das tentativas de renovação dos programas de ensino de Matemática no estado de São Paulo pós-64

The present study is the result of joint actions between education, research and outreach that is focused on the training of educators and its implications for the renovation of teaching Mathematics. Its objective is to analyze the attempts to reorganize in mathematics curriculum implemented in the state of São Paulo in the post-64. It makes use of documentary analysis and interviews of teachers for reasons of discussion and conclusions. Situated in the theoretical and methodological context of collaborative research and historical-cultural theory. The research results which shows that mathematical activity is the centrality of the discussion about learning mathematics, which has consequences for the organization, of teaching programs. This is a genesis school thinking that motivates the students to the reconstruction of ideas and thinking a production process in the classroom that considers the conditions of the school, other than the conditions that governs the production of knowledge of mathematical science, which requires thinking about the formation of a teacher epistemologically curious.
