13. AvaliaÃÃo dos efeitos renais da fraÃÃo L-aminoÃcido Oxidase isolada do veneno da serpente Bothrops marajoensis. / Assessment of renal effects of L-amino acid oxidase fraction isolated from snake Bothrops marajoensis venom.
There are about 3.000 species of snakes worldwide, but only 10 to 14% are venomous. Among South American countries, Brazil is the one with the largest number of accidents, with approximately 20.000 snakebites each year. According to the Department of Health of Brazil, the genus Bothrops are the main involved in snakebites in the country. Acute renal failure

14. Estudo dos efeitos renais do veneno da serpente Lachesis muta muta. / Study of renal effects of Lachesis muta muta venom.
The accident caused by the snake Lachesis muta muta is serious and its venom is responsible for many systemic changes, such as hypotension. In this work, the renal effects of the total venom of this snake in the renal perfusion system and in cultured renal tubular cells of the type MDCK (Madin-Darby Canine Kidney) are investigated. Isolated kidneys from Wist

15. 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

16. Sistemas de análises químicas em fluxo explorando mecanismos de re-alimentação, calibração multivariada e outras abordagens para melhoria em desempenho / Flow systems exploiting feed-back mechanisms, multivariate calibration and other strategies for improving the analytical performance
Studies focusing on performance of intelligent analytical flow systems, association with multivariate calibration or use of nanocrystals as sensitizers were carried out. Moreover, improvements related to modifications in flow pattern were evaluated with emphasis to in-line dialysis. To this end, a strategy for implementing simultaneous determinations of iron

17. Controle de degrane e conservação pós-colheita sob CaCI2 e 1-MCP de uva "Isabel‟ produzida no Vale do Sirijí(PE/PB) / Berry drop control and postharvest conservation under CaCl2 and 1-MCP grape "Isabel‟ produced in the Sirijí Valley (PE/PB).
The larger quality problem of table grape is related to the ease berry drop or abscission of berries after harvest of clusters, due to the development of the abscission zone. This study aimed to evaluate the effect of calcium chloride (CaCl2) and 1-MCP (1-methylcyclopropene), on postharvest conservation under different storage conditions of Isabel‟ gra

18. Avaliação das propriedades de transporte de massa contendo adições minerais / Evaluation of the mass transport containing mineral admixtures
A durabilidade das estruturas de concreto armado é prejudicada pela ação deteriorante da penetração de substâncias na forma de gases, vapores e líquidos através de poros e fissuras. Sabe-se que a água, tanto no seu estado puro ou com íons dissolvidos, como os cloretos, sulfato, dióxido de carbono ou oxigênio, pode comprometer a durabilidade das e

19. ESTUDO DOS EFEITOS RENAIS E VASCULARES DO VENENO DA SERPENTE Crotalus durissus cumanensis E CROTOXINA / RENAL AND VASCULAR EFFECTS FROM Crotalus durissus cumanensis VENOM AND CROTOXIN
Ophidian accidents involving species of the genus Crotalus, are usually serious and frequently fatal due to the frequency of acute renal failure. Unfortunately, there have been few studies of the toxinologic effects of Crotalus durissus cumanensis venom. The renal effects of the venom used in this study were observed by perfusion of isolated kidneys. Infusio

20. TMEM16 proteins: the long awaited calcium-activated chloride channels?
Currents mediated by calcium-activated chloride channels (CaCCs), observed for the first time in Xenopus oocytes, have been recorded in many cells and tissues ranging from different types of neurons to epithelial and muscle cells. CaCCs play a role in the regulation of excitability in neurons including sensory receptors. In addition, they are crucial mediato

21. Physiological implications of the regulation of vacuolar H+-ATPase by chloride ions
Vacuolar H+-ATPase is a large multi-subunit protein that mediates ATP-driven vectorial H+ transport across the membranes. It is widely distributed and present in virtually all eukaryotic cells in intracellular membranes or in the plasma membrane of specialized cells. In subcellular organelles, ATPase is responsible for the acidification of the vesicular inte

22. Avaliação das propriedades de transporte de massa contendo adições minerais / Evaluation of the mass transport containing mineral admixtures
The durability of reinforced concrete structures is damaged by the degrading action of the penetration of substances in the form of gases, vapors and liquids through the pores and cracks. It is known that water both in its pure form or containing dissolved ions such as chloride, sulphate, carbon dioxide or oxygen ions, can compromise the durability of concre

23. Desidratação osmotica e secagem convectiva de maçã : transferencia de massa e alterações de estrutura celular / Osmotic dehydrations and convective drying apple; : mass transfer and cellular structure changes
In this study it was investigated the osmotic dehydration of apples (Fuji variety) followed or not by convective drying with hot air. Concentration profiles were determined for water and solute(s) in samples of apples cut in half and osmotically dehydrated in binary aqueous solutions (30% and 50% sucrose, w/w) and ternary solution (50% sucrose and 10% sodium

24. Evaluation of the viability of fungi encapsulated and stored at different temperatures / AVALIAÃÃO DA VIABILIDADE DE FUNGOS ENCAPSULADOS E ARMAZENADOS EM DIFERENTES TEMPERATURAS
Cellular immobilization represents an alternative for the bioprocess conduction, where the cells are kept in a matrix and can be used over long periods. This work was conducted with the objective to test a fungi immobilization methodology with reduced cost, to evaluate the viability of these fungi when submitted to the new encapsulation method, and to determ
