1. Environmental Enrichment Promotes Antioxidant Effect in the Ventrolateral Medulla and Kidney of Renovascular Hypertensive Rats
Resumo Fundamento: A hipertensão arterial é um precursor para o desenvolvimento da insuficiência cardíaca e renal e, além disso, está associada com o aumento dos marcadores oxidativos. O enriquecimento ambiental dos roedores melhora o desempenho em tarefas de memória, e também parece ter um efeito antioxidante sobre o hipocampo dos ratos normotensos

2. Renovascular hypertension increases serum TNF and CX3CL1 in experimental Trypanosoma cruzi infection
Trypanosoma cruzi triggers a progressive inflammatory response affecting cardiovascular functions in humans and experimental models. Angiotensin II, a key effector of the renin-angiotensin system, plays roles in mediating hypertension, heart failure, and inflammatory responses. T. cruzi and AngII can induce inflammatory responses by releasing inflammatory me

3. Intermittent claudication and severe renal artery stenosis are independently associated in hypertensive patients referred for renal arteriography
OBJECTIVE: The purpose of this study was to evaluate the association between the presence of clinical symptoms of peripheral artery disease and severe renal artery stenosis in patients referred for renal angiography. METHOD: We included 82 patients with clinical suspicion of renovascular hypertension and performed an imaging investigation (renal Doppler ul

4. Time-course effects of aerobic exercise training on cardiovascular and renal parameters in 2K1C renovascular hypertensive rats
Exercise training (Ex) has been recommended for its beneficial effects in hypertensive states. The present study evaluated the time-course effects of Ex without workload on mean arterial pressure (MAP), reflex bradycardia, cardiac and renal histology, and oxidative stress in two-kidney, one-clip (2K1C) hypertensive rats. Male Fischer rats (10 weeks old; 150�

5. Nephron-sparing surgery for treatment of reninoma: a rare renin secreting tumor causing secondary hypertension
Main findings A 25-year-old hypertensive female patient was referred to our institution. Initial workup exams demonstrated a 2.8 cm cortical lower pole tumor in the right kidney. She underwent laparoscopic partial nephrectomy without complications. Histopathologic examination revealed a rare juxtaglomerular cell tumor known as reninoma. After surgery, she r

6. Combined aliskiren and L-arginine treatment has antihypertensive effects and prevents vascular endothelial dysfunction in a model of renovascular hypertension
Angiotensin II is a key player in the pathogenesis of renovascular hypertension, a condition associated with endothelial dysfunction. We investigated aliskiren (ALSK) and L-arginine treatment both alone and in combination on blood pressure (BP), and vascular reactivity in aortic rings. Hypertension was induced in 40 male Wistar rats by clipping the left rena

7. Determinants of severe coronary artery disease in hypertensive patients with indications of renal angiography for suspected renal artery stenosis / Estudo dos determinantes de doença arterial coronária grave em pacientes hipertensos com indicação de arteriografia renal por suspeita de estenose de artéria rena
INTRODUÇÃO: Em pacientes hipertensos com suspeita de doença arterial coronária (DAC), indicações para a realização de arteriografia renal no mesmo procedimento da cinecoronariografia estão bem estabelecidas. Entretanto, em hipertensos com suspeita de estenose de artéria renal (EAR) com indicação de arteriografia renal, não estão bem definidos o

8. Efeito do Óxido Nítrico na Regulação de Parâmetros Cardiovasculares pela CVLM em Ratos com Hipertensão Renovascular 2R1C / Efeito do Óxido Nítrico na Regulação de Parâmetros Cardiovasculares pela CVLM em Ratos com Hipertensão Renovascular 2R1C
Hypertension may occur due to hyperactivity of neurons in the rostral ventrolateral medulla (RVLM) (Chan et al. 1991; Boone and McMillen, 1994, Suzuki et al. 1994; Minson et al., 1996) and/or due to a reduced tone of GABAergic neurons of the caudal ventrolateral medulla (CVLM) that projects to the RVLM. Furthermore, during hypertension occurs an elevation of

9. The role of nephrectomy of the atrophic kidney in bearers of renovascular hypertension
PURPOSE: Evaluation of the beneficial effect of nephrectomy of the atrophic kidney on blood pressure (BP) and renal function. MATERIALS AND METHODS: A retrospective study of 51 patients with renovascular hypertension (RVH), bearers of atrophic kidney due to severe stenosis or occlusion of the renal artery. Average age was 47.1 ± 15 years, the median creatin

10. Glomerular filtration rate measured by 51Cr-EDTA clearance: evaluation of captopril-induced changes in hypertensive patients with and without renal artery stenosis
INTRODUCTION: Renal artery stenosis can lead to renovascular hypertension; however, the detection of stenosis alone does not guarantee the presence of renovascular hypertension. Renovascular hypertension depends on activation of the renin-angiotensin system, which can be detected by functional tests such as captopril renal scintigraphy. A method that allows

11. Cardiovascular effects of chronic vitamin C treatment in the renovascular hypertension in Wistar rats. / Efeitos cardiovasculares ao tratamento crônico com vitamina C na hipertensão renovascular em ratos Wistar.
A hiperatividade vasomotora simpática e a disfunção do reflexo barorreceptor (RB) estão envolvidas no desenvolvimento e manutenção da hipertensão arterial (HA) renovascular de Goldblatt 2 rins, 1 clipe (2R-1C). Este modelo experimental de HA é considerado dependente da ativação do sistema renina-angiotensina, sendo que a interação da angiotensina

12. Avaliação morfofuncional e molecular do detrusor isolado de ratos hipertensos renovasculares / Morphofunction and molecular evaluation of isolated detrusor on renovascular hypertensive rat model
A hipertensão renovascular é uma forma secundária da hipertensão arterial, que corresponde de 1-5% dos casos de hipertensão. A associação entre hipertensão arterial e disfunções miccionais foi observada no modelo experimental de ratos espontaneamente hipertensos (SHR). Até o momento nenhum estudo avaliou as disfunções miccionais em animais hiper
