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. Regurgitação valvar funcional em insuficiência cardíaca congestiva descompensada: monitoração não-invasiva por bioimpedância cardíaca e ecocardiografia e resposta à terapêutica / Functional valvular incompetence in decompensated heart failure: noninvasive monitoring and response to medical management.
Objective: We hypothesized that functional mitral and tricuspid valvular incompetence (MR and TR, respectively) are reversible causes of reduced cardiac output in decompensated heart failure (DF) that accompanies systolic dysfunction in ischemic or nonischemic cardiomyopathy. Background: DF, defined as signs and symptoms of heart failure at rest, is rooted i

17. Efeitos de esteróides cardiotônicos endógenos na função renal de ratos. / Effects of endogenous cardiotonic steroids in the function kidney of rats.
Bufodienolídeos são cardiotônicos esteróides estruturalmente relacionados aos cardenolídeos usualmente utilizados na clínica como, por exemplo, a digoxina. Alguns bufodienolídeos podem ser detectados no plasma e urina de mamíferos e sua significância pato/fisiológica tem sido alvo de intensa investigação recentemente. Estudos demonstram que a pro

18. Efeitos renais promovidos pelo veneno da serpente Bothrops atrox e liberaÃÃo sistÃmica de Ãxido nÃtrico / Renal effects promoted by snake Bothrops atrox venom and systemic release of nitric oxide
As serpentes do gÃnero Bothrops sÃo responsÃveis pela maior parte dos acidentes ofÃdicos ocorridos no Brasil, representando um sÃrio problema de saÃde pÃblica pela freqÃÃncia com que ocorrem e pela morbidade e mortalidade que ocasionam. Envenenamento por serpente Bothrops atrox conduz à alteraÃÃo sistÃmica que à responsÃvel pela causa prelimin

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. CaracterizaÃÃo das atividades cardiorenal e neural de Bothrops marajoensis e suas fraÃÃes / CHARACTERIZATION OF TOTAL VENOM AND ITS FRACTION FROM THE Bothrops marajoensis IN CARDIORENAL AND NEURAL ACTIVITIES
Avaliou-se a atividade de Bothrops marajoensis (Bmj) e suas fraÃÃes no sistema cardiorrenal. A resposta pressora do veneno bruto demonstrou uma diminuiÃÃo da pressÃo arterial mÃdia e da freqÃÃncia cardÃaca, sem alteraÃÃes significativas na freqÃÃncia respiratÃria. Em ratos atropinizados demonstrou a permanÃncia dos efeitos. Na perfusÃo de cor

21. Estudo dos efeitos da alta ingestÃo de cloreto de sÃdio por via oral sobre o metabolismo diÃrio e funÃÃo renal de ratos. / Study of effects on the daily metabolism and the renal function of rats under high oral ingestion of sodium chloride.
Guanylin (GN), uroguanylin (UGN), and the bacterial heat-stable enterotoxin (ST) peptides comprise a new family of cyclic guanosine 3â-5â monophosphate (cGMP)-regulating agonist. Ingestion of a salt meal induces secretion of GN and UGN into the intestinal lumen, where they inhibit Na+ absorption and induces Cl-, HCO3- , and water secretion. Simultaneously,

22. Antivenom action on renal effects induced by Thalassophryne nattereri venom
Thalassophryne nattereri (niquim) is a venomous fish responsible for numerous accidents involving fishermen in northern and northeastern Brazil. The aim of the present investigation was to evaluate the action of antivenom on renal effects caused by Thalassophryne nattereri venom. Isolated kidneys of Wistar rats were perfused with a previously dialyzed Krebs-

23. Comparison between clinical stratification and myocardial perfusion scintigraphy as a predictor of cardiovascular events in kidney transplant candidates / Comparação entre a estratificação clínica e a cintilografia de perfusão miocárdica como preditores de eventos cardiovasculares em candidatos a transplante renal
Cardiovascular (CV) disease is a common condition in chronic kidney disease (CKD) patients and is the leading cause of fatal events during and after renal transplantation. The best strategy for CV evaluation and coronary risk stratification in renal transplant candidates remains controversial. Moreover, there is no consensus regarding the best strategy for d

The hepatic transplant is the standard treatment for terminal hepatic illness. With the refinement of the surgical technique, improvement of the effectiveness of the immunosuppressive drugs, the better knowledge of the reperfusion injury and the use of more physiological solutions of preservation, had a considerable increase of the survival of hepatic graft.
