13. The impact of metabolic syndrome on metabolic, pro-inflammatory and prothrombotic markers according to the presence of high blood pressure criterion
OBJECTIVES: We explored whether high blood pressure is associated with metabolic, inflammatory and prothrombotic dysregulation in patients with metabolic syndrome. METHODS: We evaluated 135 consecutive overweight/obese patients. From this group, we selected 75 patients who were not under the regular use of medications for metabolic syndrome as defined by

14. Effects of the administration of a catalase inhibitor into the fourth cerebral ventricle on cardiovascular responses in spontaneously hypertensive rats exposed to sidestream cigarette smoke
OBJECTIVE: Previous studies have demonstrated a relationship between brain oxidative stress and cardiovascular regulation. We evaluated the effects of central catalase inhibition on cardiovascular responses in spontaneously hypertensive rats exposed to sidestream cigarette smoke. METHODS: Male Wistar Kyoto (WKY) rats and spontaneously hypertensive rats (S

15. Pleiotropic effects of simvastatin in physically trained ovariectomized rats
This study tested the hypothesis that simvastatin treatment can improve cardiovascular and autonomic functions and membrane lipoperoxidation, with an increased effect when applied to physically trained ovariectomized rats. Ovariectomized rats were divided into sedentary, sedentary+simvastatin and trained+simvastatin groups (n = 8 each). Exercise training was

16. Controle cardiovascular em fêmeas ooforectomizadas diabéticas: efeitos do treinamento físico dinâmico aeróbio, resistido ou combinado / Cardiovascular control in female diabetic ovariectomized rats: effects of dynamic aerobic, resistance and combined exercise training
Aerobic exercise training induces attenuation of cardiometabolic disorders that affect postmenopausal and/or diabetic women. However, there few and controversial studies involving resistance or combined training (aerobic + resistance) in these conditions. Thus, the objectives of this study were to evaluate the metabolic, cardiac, hemodynamic and autonomic ef

17. INFLUÊNCIA DO HIPOTIREOIDISMO GESTACIONAL EXPERIMENTAL SOBRE A FUNÇÃO CARDIOVASCULAR DA PROLE DE RATAS. / INFLUENCE OF EXPERIMENTAL GESTATIONAL HYPOTHYROIDISM ON CARDIOVASCULAR FUNCTION ALONG THE LIFE OF OFFSPRING IN RATS.
Gestational hypothyroidism is a prevalent disorder in pregnant women. We aimed to investigate the impact of experimental gestational hypothyroidism (EGH) on cardiovascular and autonomic nervous systems (ANS) in the offspring of rats. EGH was induced with methimazole (MMI) 0.02% in drinking water from day 9 of gestation until birth. Sixty days old offspring f

18. Monosodium glutamate neonatal treatment induces cardiovascular autonomic function changes in rodents
OBJECTIVES: The aim of this study was to evaluate cardiovascular autonomic function in a rodent obesity model induced by monosodium glutamate injections during the first seven days of life. METHOD: The animals were assigned to control (control, n = 10) and monosodium glutamate (monosodium glutamate, n = 13) groups. Thirty-three weeks after birth, arterial an

19. Time course of the hemodynamic responses to aortic depressor nerve stimulation in conscious spontaneously hypertensive rats
The time to reach the maximum response of arterial pressure, heart rate and vascular resistance (hindquarter and mesenteric) was measured in conscious male spontaneously hypertensive (SHR) and normotensive control rats (NCR; Wistar; 18-22 weeks) subjected to electrical stimulation of the aortic depressor nerve (ADN) under thiopental anesthesia. The parameter

20. Avaliação da função ventricular sistólica e diastólica pelo ecocardiograma transesofágico e da capacidade funcional em ratos espontaneamente hipertensos submetidos à desnervação sino-aórtica / Evaluation of the systolic and diastolic ventricular function by transesophageal echocardiogram and functional capacity in spontaneously hypertensive rats submitted to sinoaortic denervation
INTRODUÇÂO: Durante o desenvolvimento da hipertensão arterial sistêmica (HAS) ocorre a hiperatividade simpática, que está relacionada ao comprometimento dos sistemas baro e quimiorreflexo arteriais e disfunção ventricular esquerda (VE). Entretanto, a função ventricular direita (VD) tem sido pouco avaliada no contexto da HAS associada à desnervaç�

21. Influência da integridade dos barorreceptores nos ajustes morfofuncionais cardíacos à hipertensão espontânea em ratos / Influence of baroreceptor integrity on cardiac morpho-functional adjustments to spontaneous hypertension in rats
It has been demonstrated that reduced baroreflex sensitivity is an independent marker of mortality risk. The arterial baroreflex plays an important role in the maintenance of the moment-to-moment stability of blood pressure (BP). Although the contribution of blood pressure variability (BPV) to cardiovascular morbidity and mortality is well established, the m

22. Efeitos do exercício físico prévio sobre a função renal, disfunção autonômica e atividade nervosa simpática renal no diabetes mellitus experimental, em ratos / Effects of previous exercise on renal function, autonomic dysfunction and renal sympathetic nerve activity in experimental diabetes, in rats
Background: The exercise training (ET) has been recognized as an important therapeutic intervention for the chronic degenerative diseases such as Diabetes Mellitus (DM) that cause renal and cardiovascular complications. However, little is known if previous ET intervention modulates the physiological and medical impact caused by these dysfunctions. We investi

23. Atividade vasomotora simpática em um modelo experimental de obesidade induzida por dieta hiperlipídica / Sympathetic vasomotor activity in an experimental model of obesity induced by high fat diet
A obesidade está relacionada a problemas cardiovasculares, como hipertensão arterial (HA) e suas co-morbidades, bem como, a alterações metabólicas como resistência à insulina, hiperglicemia, dislipidemias, dentre outras alterações típicas da síndrome metabólica (SM). Existem evidências de que a obesidade está relacionada ao aumento da atividade

24. Cardiac and renal effects induced by different exercise workloads in renovascular hypertensive rats
We examined the effect of exercise training (Ex) without (Ex 0%) or with a 3% workload (Ex 3%) on different cardiac and renal parameters in renovascular hypertensive (2K1C) male Fisher rats weighing 150-200 g. Ex was performed for 5 weeks, 1 h/day, 5 days/week. Ex 0% or Ex 3% induced similar attenuation of baseline mean arterial pressure (MAP, 119 ± 5 mmHg
