1. Behavioral effects of Bj-PRO-7a, a proline-rich oligopeptide from Bothrops jararaca venom
The heptapeptide Bj-PRO-7a, isolated and identified from Bothrops jararaca (Bj) venom, produces antihypertensive and other cardiovascular effects that are independent on angiotensin converting enzyme inhibition, possibly relying on cholinergic muscarinic receptors subtype 1 (M1R). However, whether Bj-PRO-7a acts upon the central nervous system and modifies b

3. Participation of hepatic α/β-adrenoceptors and AT1 receptors in glucose release and portal hypertensive response induced by adrenaline or angiotensin II
It has been previously demonstrated that the hemodynamic effect induced by angiotensin II (AII) in the liver was completely abolished by losartan while glucose release was partially affected by losartan. Angiotensin II type 1 (AT1) and adrenergic (∝1- and β-) receptors (AR) belong to the G-proteins superfamily, which signaling promote glycogen breakdown a

4. Candesartan, rather than losartan, improves motor dysfunction in thioacetamide-induced chronic liver failure in rats
Minimal hepatic encephalopathy is more common than the acute syndrome. Losartan, the first angiotensin-II receptor blocker (ARB), and candesartan, another widely-used ARB, have protected against developing fibrogenesis, but there is no clear data about their curative antifibrotic effects. The current study was designed to examine their effects in an already-

5. Angiotensin II type 1 and 2 receptors and lymphatic vessels modulate lung remodeling and fibrosis in systemic sclerosis and idiopathic pulmonary fibrosis
OBJECTIVE: To validate the importance of the angiotensin II receptor isotypes and the lymphatic vessels in systemic sclerosis and idiopathic pulmonary fibrosis. METHODS: We examined angiotensin II type 1 and 2 receptors and lymphatic vessels in the pulmonary tissues obtained from open lung biopsies of 30 patients with systemic sclerosis and 28 patients wi

6. Resposta à angiotensina II em artérias mesentéricas de resistência na obesidade: participação das MAPKs. / Differential participation of MAPKs in angiotensin II-induced contraction in obesity.
A angiotensina II (AngII) pode ativar as vias de sinalização das proteínas quinases ativadas por mitógenos (MAPKs). Investigamos o papel da obesidade e das MAPKs na resposta à AngII em ratos obesos por injeção de glutamato monossódico (Ob). Artérias mesentéricas de resistência com endotélio intacto e não as artérias sem endotélio, isoladas de

7. The effect of losartan on angiotensin II-induced cell proliferation in a rat aorta smooth muscle cell line
The success of revascularization procedures is limited by recurrent stenosis, which is a narrowing of a blood vessels that results from neo-intimal hyperplasia. The renin-angiotensin-aldosterone system has been implicated in the pathogenesis of neo-intimal hyperplasia, and a role for angiotensin II in vascular smooth muscle cell proliferation has been propos

8. Angiotensin II type 1 receptor blockade partially attenuates hypoxia-induced pulmonary hypertension in newborn piglets: relationship with the nitrergic system
The objective of this study was to observe possible interactions between the renin-angiotensin and nitrergic systems in chronic hypoxia-induced pulmonary hypertension in newborn piglets. Thirteen chronically instrumented newborn piglets (6.3 ± 0.9 days; 2369 ± 491 g) were randomly assigned to receive saline (placebo, P) or the AT1 receptor (AT1-R) blocker

9. Indução de receptor B1 de cininas em vasos sanguineos de ratos hipertensos por infusão de angiotensina II: estudo molecular e funcional. / Induction of kinin B1 receptor in blood vessels of angiotensin II-hypertensive rats: molecular and functional studies
O objetivo deste estudo foi avaliar se a infusão de angiotensina II (ANG II) modulava a expressão do receptor B1 (RB1) de cininas em aorta (AO),arteríolas mesentéricas (AM) de ratos Wistar e também verificar a influência do RB1 na pressão arterial e reatividade desses vasos sanguíneos através do agonista de RB1, DABK. Os ratos receberam por 28 dias

10. Efeito potencializador da Angiotensina(1-7) sobre o aumento da tensão sistólica induzida pelo isoproterenol em corações isolados de ratos
The present study was designed to establish the possible interaction between the Angiotensin-(1-7) [Ang-(1-7)] with isoproterenol, adrenergic agonist, in the production of increased myocardial contractility of isolated hearts of adult rats. Hearts were perfused according to Langendorff preparation. It was used first bolus of isoproterenol, laterally to the a

11. Gadolinium increases the vascular reactivity of rat aortic rings
Gadolinium (Gd) blocks intra- and extracellular ATP hydrolysis. We determined whether Gd affects vascular reactivity to contractile responses to phenylephrine (PHE) by blocking aortic ectonucleoside triphosphate diphosphohydrolase (E-NTPDase). Wistar rats of both sexes (260-300 g, 23 females, 7 males) were used. Experiments were performed before and after in

12. Papel dos receptores B1 e B2 de bradicinina e de captopril nas interações célula hospedeira-Trypanosoma cruzi
The infection of monocytes by Trypanosoma cruzi tripomastigotes is a crucial step for the development of Chagas disease immune response. Infection by T. cruzi has demonstrated to be an active process, involving diverse cellular components and different cell types. Previous studies of the interaction tissue-culture derived trypomastigotes (TCT) between cardio
