13. Characterization of the photosynthetic conditions and pigment profiles of the colour strains of Hypnea musciformis from field-collected and in vitro cultured samples
Hypnea musciformis (Wulfen) JV Lamour. is a species of great economic interest as it produces Κ-carrageenan and has shown biological activities against HIV and HSV viruses. This species displays different colour strains in its natural habitat, which may have implications for the biotechnological potential of the species. The aim of this study was to charact

15. Avaliação dos efeitos do betabloqueador nebivolol sobre o peritônio em modelo experimental murino de diálise peritoneal / Assessment of the effects of beta-blocker nebivolol on the peritoneum in an experimental murine model of peritoneal dialysis
A falência de ultrafiltração (UFF) é uma causa importante de interrupção da diálise peritoneal (DP) enquanto terapia renal substitutiva. Além da inflamação crônica e aguda causadas à membrana peritoneal (MP) pelos produtos de degradação da glicose, produtos avançados da glicosilação, pH ácido das soluções e infecções, -bloqueadores (BB)

16. Aplicabilidade e validação do Geant4 para fótons e elétrons em radioterapia / GEANT4 applicability and validation to Photons and Electrons in Radiotherapy
Due to the increasing use of ionizing radiation in medical applications, in recent decades, the simulation codes for radiation interacting with matter, based on Monte Carlo Method, have been constantly adapted to applications in medical physics. TheMonte Carlo method is a statisticalmethod of numerical simulation of problems using essentially a sequence of r

17. Avaliação dos procedimentos higiênico-sanitários utilizados durante a coleta domiciliar e o transporte do leite humano ordenhado / Assessment of the hygienic-sanitary procedures used during collection and transportation of household human milk
The breastfeeding is considered one of the main strategies for child survival and the Human Milk (HM) is the ideal food for the term newborn and pre-term newborn, with the capabilities to supply essential nutrients for their development. In the absence or insufficient volumes of milk from their mother, especially for hospitalized children as newborns pre-ter

18. Caracterização da função biológica da vitamina K biossintetizada pelas formas intraeritrocitárias de Plasmodium falciparum. / Analysis of the biological function of the vitamin K biosynthesized by intraerytrocytic forms of Plasmodium falciparum.
A falta de uma vacina eficaz e o problema da resistência aos fármacos têm dificultado o controle da malária. A busca de novos alvos biológicos para o desenvolvimento de antimaláricos eficazes tem se concentrado, em parte, na pesquisa e compreensão de vias metabólicas exclusivas do parasita. Nosso grupo vem investigando e caracterizando produtos da bi

19. Macroinvertebrates associated with bryophyta in a first-order Atlantic Forest stream
This study describes the composition and structure of the benthic community associated with bryophytes in a first-order stream, located in a biological reserve of the Atlantic Forest, during two seasons. During three months of the dry season of 2007 and three months of the rainy season of 2008, samples of bryophytes attached to stones were collected randomly

20. Identificação de interatores putativos envolvidos na localização de proteínas de duplo direcionamento em Arabidopsis thaliana / Identification of putative interactors involved in the localization of dual-targeted proteins in Arabidopsis thaliana
Most organellar proteins are nuclear encoded, synthesized in the cytosol and then targeted to their destination. Specific subcellular targeting is conducted by a complex machinery for the specific localization of the proteins, which includes targeting sequences, cytosolic proteins and specific organelar receptors. However, little is known about the process t

21. Purification and biological effects of a C-type lectin isolated from Bothrops moojeni
Snake venom proteins from the C-type lectin family have very distinct biological activities despite their highly conserved primary structure, which is homologous to the carbohydrate recognition region of true C-type lectins. We purified a lectin-like protein (BmLec) from Bothrops moojeni venom and investigated its effect on platelet aggregation, insulin secr

23. Seleção de leveduras para bioconversão de D-xilose em xilitol / Yeast selection for bioconversion of D-xylose to xilitol
Microbial species, particularly yeast, are of great importance for the production of xylitol. The xylitol production involves complicated metabolic regulation, including the transport of D-xylose, production of key enzymes and cofactor regeneration. Thus, screening of microorganisms that consume D-xylose naturally becomes a viable and effective way to obtain

24. Desenvolvimento e validação de metodologia analítica para determinação de hidrocarbonetos policíclicos aromáticos (HPAS) em sedimentos. Avaliação da represa do Parque Pedroso, Santo André, SP / Development and validation of analytical methodology for determination of polycyclic aromatic hydrocarbons (PAHs) in sediments. Assessment of Pedroso Park Dam, Santo André, SP
The polycyclic aromatic hydrocarbons (PAHs), by being considered persistent contaminants, by their ubiquity in the environment and by the recognition of their genotoxicity, have stimulated research activities in order to determine and evaluate their sources, transport, processing, biological effects and accumulation in compartments of aquatic and terrestrial
