Evaluating of the activity antioxidant and fatty acids profile of lychee seeds (Litchi chinensis SONN.)

Purpose: The purpose of this paper is to characterize lychee seeds regarding their centesimal composition, and also to evaluate their antioxidant potential and fatty acid profile. Design/methodology/approach: To obtain the extract, dehydrated and grinded seeds were extracted with ethyl alcohol for 30 min, at a proportion of 1:3 of seeds:ethyl alcohol, under continuous agitation, at room temperature. Afterwards, the mixture was filtered and the supernatant subjected to a rotoevaporator at 40oC aiming to determine, by direct weighing, the extract dry matter yield. Findings: The largest found values went to the total carbohydrates (72.75 percent). In the oil from the lychee seeds there was a high percentage of unsaturated fatty acids, the main component being linoleic, considered an essential fatty acid. Research limitations/implications: Implies the identification of compounds biativos extracted from seeds of tropical and subtropical fruits, and to prevent certain types of diseases. Originality/value: The article tries to identify new source of phenolic compounds extracted from fruit. © Emerald Group Publishing Limited.

Metodologias de pesquisa para o estudo geográfico da sociabilidade juvenil

This study aims to present the methodologies of research used to carry out the dissertation requirements related to the different times and spaces linked to the youth sociability. The methodologies are about qualitative features not at all unknown to the geography studies despite the little account taken on them. The methodologies are: eyewitness accounts, Oral History, interviews and groups of debate. With this purpose, this work intends to bring some contribution to geographers and beginners that have been looking for methodological references to their researches it also tries to facilitate the discussion on the methodological dimension in the geographical studies.

Soursop (Annona muricata L.) and sugar apple (Annona squamosa L.): Antioxidant activity, fatty acids profile and determination of tocopherols

Purpose: This study aims to analyze the soursop and sugar apple seeds as to its composition, to evaluate the antioxidant potential of seeds extract and characterize the oil extracted from them, regarding the fatty acids profile and content of tocopherols. Design/methodology/approach: To obtain the extracts, dried and crushed seeds were extracted with ethanol for 30 minutes, at a ratio of 1:3 (m/m, seed: ethyl alcohol) under continuous stirring at room temperature. Then, the mixture was filtered and the supernatants subjected to rotoevaporator at 40°C aiming to determine, by direct weighing, the yields of dry extracts. Findings: According to the results, the soursop and sugar apple seeds constituted significant sources of lipids, proteins and carbohydrates and can therefore be used in food and feed, and offer relevant antioxidant activity of phenolic compounds. The oil seeds are a good source of unsaturated fatty acids, especially oleic and linoleic acids and they have significant amounts of total tocopherol. Research limitations/implications: Implications are the identification of bioactive compounds extracted from seeds of tropical and subtropical fruits, and to prevent certain types of diseases. Practical implications: The information presented might be directly used for developing of functional foods such as fruits. Originality/value: The article tries to identify new source of compounds extracted from fruits. © Emerald Group Publishing Limited.

It only takes one to do many jobs: Amphotericin B as antifungal and immunomodulatory drug

Amphotericin B acts through pore formation at the cell membrane after binding to ergosterol is an accepted dogma about the action mechanism of this antifungal, and this sentence is widely found in the literature. But after 60 years of investigation, the action mechanism of Amphotericin B is not fully elucidated. Amphotericin B is a polyene substance that is one of the most effective drugs for the treatment of fungal and parasite infections. As stated above, the first mechanism of action described was pore formation after binding to the ergosterol present in the membrane. But it has also been demonstrated that AmB induces oxidative damage in the cells. Moreover, amphotericin B modulates the immune system, and this activity has been related to the protective effect of the molecule, but also to its toxicity in the host. This review tries to provide a general overview of the main aspects of this molecule, and highlight the multiple effects that this molecule has on both the fungal and host cells. © 2012 Mesa-Arango, Scorzoni and Zaragoza.

A memória dos carnavais Afro-Paulistanos na cidade de São Paulo nas décadas de 20 e 30 do século XX

Current analysis deals with memoirs of Carnivals celebrated by Negroes in the city of São Paulo during the 1920s and 1930s. The narrative tries to investigate the trajectory of the Afro-Brazilian group and the spaces used to express its performances during the festivities dedicated to Momo throughout the city of São Paulo, which was still characterized by wealthy people that controlled its several sections. Several discussions are endeavored to perceive the spaces fabricated by the group and its strategy to get together and celebrate Carnival (officially or non-officially). The form and meanings of playful art represented by such festivities are also highlighted.
