3. THE MULTIROLE OF MODIFIED NATURAL GUMS FOR MULTICOMPONENT POLYMERS: AS COUPLING AGENTS FOR POLYMERS REINFORCED WITH CELLULOSIC FIBERS OR COMPATIBILIZERS FOR BIODEGRADABLE POLYMER BLENDS
In this work, the capability to use pine rosin as a biodegradable coupling agent/compatibilizer is studied. To formulate composites, post-consumer polypropylene and discarded agave fibers (as reinforcing agent) are coupled with pine rosin (in pure or maleated form). Besides, poly(lactic acid) (PLA) with poly(butylene adipate-co-terephthalate) (PBAT) are comp

4. Antiviral activity of animal venom peptides and related compounds
Abstract Viruses exhibit rapid mutational capacity to trick and infect host cells, sometimes assisted through virus-coded peptides that counteract host cellular immune defense. Although a large number of compounds have been identified as inhibiting various viral infections and disease progression, it is urgent to achieve the discovery of more effective agent

5. Preparation and Characterization of Nanowhiskers Cellulose from Fiber Arrowroot (Maranta arundinacea)
The agribusiness generates countless sources of biomass that are not appropriately and / or adequately utilized, turning them into industrial wastes. This study aims to explore the Arrowroot fiber as a source of raw material for the cellulose nanowhiskers production by acidic hydrolysis. Hydrolyses were carried out varying the temperature and the sulfuric ac

6. Effect of reinforcement nanoparticles addition on mechanical properties of SBS/curauá fiber composites
Composites of styrene-butadiene-styrene triblock copolymer (SBS) matrix with curauá fiber and/or a nanoparticulate mineral (montmorillonite clay - MMT) used as reinforcing agents were prepared by melt-mixing. The influence of clay addition on properties like tensile and tear strength, rebound resilience, flex fatigue life, abrasion loss, hardness and water

7. Efeito da creatina e do piruvato sobre alguns parâmetros comportamentais e bioquímicos em ratos submetidos à administração intra-hipocampal de fenilalanina
The objective of this work was to investigate the possible preventive effect of pyruvate and creatine (substances with energetic and antioxidant properties) on the behavioral and biochemical alterations caused by intrahippocampal administration of phenylalanine (Phe) in Wistar rats. It was developed a experimental chemical model of phenylketonuria(PKU) by in

9. Characterization of Listeria monocytogenes and Yersinia enterocolitica isolated from slaughterhouses and pork in São Paulo State and their comparision with isolates from clinic cases in humans / Caracterização de Listeria monocytogenes e Yersinia enterocolitica isoladas em abatedouros e cortes de carne suína no Estado de São Paulo e sua comparação com isolados de casos clínicos em humanos
Listeria monocytogenes and Yersinia enterocolitica are zoonotic agents with capacity of transmission through foods, including pork. The present study evaluated, monthly, from May 2007 to April 2008, several points of swine meat productive chain in slaughterhouses and butcheries from Sao Paulo state. It were evaluated the environments of visited establishment

10. Uma floresta politizada : relações políticas na Reserva Extrativista do Alto Juruá, Acre (1994-2002) / A politicized forest : political relationship in the Alto Juruá Extractive Reserve, Acre (1994-2002)
The Extractive Reserves appeared in the context of struggles of the dwellers in the Amazon during decades of 1970 and 1980, in order to keep their traditional territories and to improve their actuation upon the decisions about the forest future. This work intend to describe the forms of this political actuations based on historic and ethnographic researches

12. Chemical modifications in lignocellulosic fibers to obtain and use in biosensor array phenolic derivative of LCC and the biosorption of metals / Modificações químicas em fibras lignocelulósicas para obtenção e aplicação em biocompósitos de matriz fenólica derivada de LCC e na biossorção de metais
In this work, lignocellulosic fibers from two sources (sisal and banana pseudo stem) were used as reinforcing agents in the preparation of phenolic matrix composites derived from cashew nut shell liquid (CNSL) and as material to adsorb toxic metals (Pb+2, Ni+2, Cd+2, Zn+2 and Cu+2). Surface changes were induced in the sisal fibers by immersion in alkali solu
