1. Superimposing a high-fat diet on Schistosoma mansoni infection affects renin-angiotensin system components in the mouse kidney
Abstract INTRODUCTION: The levels of the full-length form of the (pro)renin receptor (PRR), a component of the renin-angiotensin system (RAS), may be reduced in the membranes of kidneys in renal diseases. This study aimed to investigate the RAS components in the kidneys of mice submitted to a combination of a high-fat diet and Schistosoma mansoni infection.

2. Antiedematogenic activity of the indole derivative N-salicyloyltryptamine in animal models
ABSTRACT The N-salicyloyltryptamine (NST) is an indole derivative compound analogue to the alkaloid N-benzoyltryptamine. In the present study, the antiedematogenic activity of NST was investigated in animal models. Firstly, the acute toxicity for NST was assessed according to the OECD Guideline no. 423. The potential NST-induced antiedematogenic activity was

3. Efeitos do conjugado estrogênio eqüino (PremarinÒ) sobre o leito venular mesentérico de SHR ovariectomizadas: papel do endotélio. / Effect of conjugated equine estrogen (PremainÒ) on the mesenteric venular bed of ovariectomized SHR: role of endothelium.
Ainda existe controvérsia se a terapia hormonal estrogênica confere benefício ou dano cardiovascular. O dano potencial causado por doses padrão de estrogênio incluindo doença cardíaca coronariana e trombose venosa pode ser atenuada por uso de doses mais baixas. O objetivo deste estudo foi avaliar o efeito do tratamento com conjugado estrogênio equino

4. Estudo das alterações cardiovasculares e metabólicas em modelo experimental de programação metabólica: efeito de extrato da casca de uva Vitis vinífera / Study of cardiovascular and metabolic alterations in experimental model of metabolic programming: effect of extract from skin of grape extract of grape Vitis vinifera
Epidemiological and experimental studies have suggested that cardiovascular risk factors can be partly attributed to the influences of the environment in which the individual lives, and that maternal nutrition influences the programming of metabolic and cardiovascular diseases in adults characterizing the metabolic syndrome. On the other hand, previous studi

5. Papel do sistema renina-angiotensina sobre a função vascular e plaquetária na gravidez normal e associada à hipertensão / Role of the renin-angiotensin system on vascular and platelet function in the normal pregnancy and pregnancy accompained by hypertension
Na gravidez a circulação sistêmica materna se adapta para favorecer a perfusão úteroplacentária e o sistema renina-angiotensina (SRA) tem um papel importante nessa adaptação. O objetivo deste estudo foi investigar a contribuição do SRA para a regulação cardiovascular materna no final da gravidez, assim como a via L-arginina-NO-GMPc em plaquetas d

6. Oral rapamycin attenuates atherosclerosis without affecting the arterial responsiveness of resistance vessels in apolipoprotein E-deficient mice
The objective of the present study was to assess the effects of the immunosuppressant rapamycin (Rapamune®, Sirolimus) on both resistance vessel responsiveness and atherosclerosis in apolipoprotein E-deficient 8-week-old male mice fed a normal rodent diet. Norepinephrine (NE)-induced vasoconstriction, acetylcholine (ACh)- and sodium nitroprusside (SNP)-indu

7. Efeitos renais e vasculares do extrato bruto da anÃmona marinha Bunodosoma caissarum e sua fraÃÃo fosfolipase a2: estudo dos mediadores envolvidos / Bunodosoma caissarum and it\ s phospholipase A2 fraction effects in the isolated perfusion kidney and arteriolar mesenteric bed
AnÃmonas marinhas contÃm uma variedade de compostos biologicamente ativos incluindo potentes toxinas. Por esta razÃo, muitos investigadores tÃm centrado seus estudos nestas proteÃnas, isoladas de anÃmonas marinhas, como Bunodosoma caissarum. O objetivo deste trabalho foi estudar o mecanismo das alteraÃÃes funcionais produzidas pelo extrato bruto e da

8. Biological effects induced by Tityus serrulatus crude venom and its toxins TsTx-V, gamma toxin and natriuretic peptide / Efeitos biolÃgicos induzidos pelo veneno total de Tityus serrulatus e suas fraÃÃes TsTx-V, toxina gama e peptÃdeo natriurÃtico
The venom of Tityus serrulatus has a mixture of toxic and non toxic peptides presenting diverse systemic and local effects. The aim of this work was to investigate the cardiovascular and renal effects promoted by the crude venom of the scorpion Tityus serrulatus and its isolated components such as Tityus serrulatus toxin V (TsTx-V), Gamma Toxin and the newly

9. Angiotensin II induced venoconstriction in normotensive and hypertensive rats: study of action mechanisms, localization and expression of AT1 and AT2 receptors. / Venoconstrição induzida por angiotensina II em ratos normotensos e hipertensos: estudo de mecanismos de ação, localização e expressão de receptores AT1 e AT2.
In this study we have evaluated and characterized the effect of Ang II in the isolated perfused mesenteric venular bed (MVB) and portal vein rings (PVR) of SHR and wistar rats. Vascular reactivity to Ang II was studied in the absence and presence of different antagonists to elucidate the mechanisms involved in Ang II-induced venoconstriction. Our results sug

10. Estudo das alterações renais e vasculares induzidas pelo veneno de Tityus serrulatus / Study of renal and blood vessel alterations induced by Tityus serrulatus venom
According to the Brazilian Ministry of Health, about 8000 cases of scorpion envenomation are reported yearly in Brazil. Most cases are due to the sting of Tityus serrulatus, known popularly as yellow scorpion. It belongs to the Arachnidea, class, Scorpionidae order, Buthidae family, Tityinae subfamily and Tityus genus. It is present in the Brazilian States o

11. Caracterização bioquímica, funcional e molecular da elastase-2 formadora de angiotensina II do leito arterial mesentérico de rato. / Biochemical, functional and molecular characterization of the rat mesenteric arterial bed elastase-2, an angiotensin II-forming enzyme.
Uma elastase-2 foi recentemente descrita como a principal enzima formadora de angiotensina (Ang) II no perfusato do leito arterial mesentérico (LAM) isolado de rato. Investigamos a interação dessa elastase-2 do perfusato do LAM isolado de rato (E-2LAMR) com alguns substratos e inibidores de elastases-2 e de quimases formadoras de Ang II. Os precursores de
