1. Baroreflex sensitivity in frailty syndrome
Frailty is related to a decrease in the physiological reserves, which causes difficulties in maintaining homeostasis. An example of physiological mechanisms for cardiovascular homeostasis is the baroreflex. The aim of this study was to compare baroreflex among frail, prefrail, and nonfrail individuals, in supine and orthostatic positions. Community-dwelling

2. Women with Polycystic Ovarian Syndrome Exhibit Reduced Baroreflex Sensitivity That May Be Associated with Increased Body Fat
Resumo Fundamento: As mulheres com síndrome do ovário policístico (SOP) apresentam alta prevalência de obesidade e alterações no controle autonômico cardiovascular, principalmente modificações na modulação autonômica da variabilidade da frequência cardíaca (VFC). No entanto, existem poucos estudos sobre outros parâmetros de controle autonômi

3. Impaired baroreflex sensitivity and increased systolic blood pressure variability in chronic post-ischemic stroke
OBJECTIVES: Acute post-stroke patients present cardiovascular autonomic dysfunction, which manifests as lower heart rate variability and impaired baroreflex sensitivity. However, few studies performed to date have evaluated cardiovascular autonomic function in chronic post-stroke patients. The aim of this study was to evaluate cardiovascular autonomic modul

4. Resting spontaneous baroreflex sensitivity and cardiac autonomic control in anabolic androgenic steroid users
OBJECTIVES: Misuse of anabolic androgenic steroids in athletes is a strategy used to enhance strength and skeletal muscle hypertrophy. However, its abuse leads to an imbalance in muscle sympathetic nerve activity, increased vascular resistance, and increased blood pressure. However, the mechanisms underlying these alterations are still unknown. Therefore, w

5. Neural mechanismsand post-exercise hypotension: The importance of experimental studies
Abstract A single bout of exercise can decrease blood pressure level in hypertensive individuals and this phenomenon is known as post-exercise hypotension (PEH). PEH is clinically important and reduces blood pressure after physical exercise in hypertensive subjects. This reduction has been attributed to autonomic mechanisms, e.g., reduced peripheral sympathe

6. Autonomic and Renal Alterations in the Offspring of Sleep-Restricted Mothers During Late Pregnancy
OBJECTIVES: Considering that changes in the maternal environment may result in changes in progeny, the aim of this study was to investigate the influence of sleep restriction during the last week of pregnancy on renal function and autonomic responses in male descendants at an adult age. METHODS: After confirmation of pregnancy, female Wistar rats were rand

7. Association of exercise training and angiotensin-converting enzyme 2 activator improves baroreflex sensitivity of spontaneously hypertensive rats
The present study sought to determine cardiovascular effects of aerobic training associated with diminazene aceturate (DIZE), an activator of the angiotensin converting enzyme 2, in spontaneously hypertensive rats (SHRs). Male SHRs (280–350 g) were either subjected to exercise training or not (sedentary group). The trained group was subjected to 8 weeks of

8. 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

9. 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

10. 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

11. 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

12. 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
