1. Dysautonomic Arrhythmogenesis: A Working Hypothesis in Chronic Chagas Cardiomyopathy
Abstract Sudden cardiac arrest (SCA) represents the most dramatic course of chronic Chagas cardiomyopathy (CCC) and is closely related to the presence of ventricular arrhythmias and heart disease. Although several aspects of ventricular arrhythmias in CCC have been elucidated in the last decades, such as the role of impaired cardiac autonomic modulation repo

2. HEART RATE VARIABILITY IN TENNIS PLAYERS
RESUMO Introdução Alguns estudos sugerem que a modalidade esportiva tênis traz benefícios aos perfis antropométrico e metabólico de seus praticantes, reduzindo o risco de mortalidade de forma mais significante que outras modalidades esportivas. Além disso, as alterações na regulação autonômica cardiovascular têm sido evidenciadas como fator co

3. Analgesic effects of Marasmius androsaceus mycelia ethanol extract and possible mechanisms in mice
Marasmius androsaceus is a medicinal fungus mainly used to treat various forms of pain in China. This study investigated the analgesic effects of an ethanol extract of M. androsaceus (MAE) and its potential molecular mechanisms. Oral administration of MAE (50, 200, and 1000 mg/kg) had significant analgesic effects in an acid-induced writhing test, a formalin

4. Efeitos da Hipóxia na Variabilidade da Frequência Cardíaca em Indivíduos Saudáveis: Uma Revisão Sistemática
Resumo Fundamento: A hipóxia é uma condição fisiológica que pode influenciar a modulação autonômica cardíaca, qualpode ser avaliada pelas flutuações espontâneas da frequência cardíaca, chamada de variabilidade da frequência cardíaca (VFC). Estudos têm reportado reduções ou manutenção da VFC em situação de hipóxia apresentando efeitos

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. Determinants of body weight regulation in humans
ABSTRACT Body weight is regulated by the ability of hypothalamic neurons to orchestrate behavioral, endocrine and autonomic responses via afferent and efferent pathways to the brainstem and the periphery. Weight maintenance requires a balance between energy intake and energy expenditure. Although several components that participate in energy homeostasis have

9. Autonomic regulation of heart rate during specific dynamic action associated with digestion in the bullfrog Lithobates catesbeianus
ABSTRACT Feeding causes a substantial rise in the aerobic metabolism of all vertebrates, which is met by a rise in heart rate to secure adequate oxygen delivery, as well as intestinal nutrient absorption and transport between organs. To study the autonomic regulation of this postprandial tachycardia in an amphibian, we placed arterial catheters in individual

10. Avaliação da reatividade cardiovascular em pacientes com esclerose múltipla
Introduction: Multiple Sclerosis (MS) is a chronic inflammatory disease characterized by the presence of demyelinating, inflammatory, and degenerative multifocal central nervous system (CNS) lesions. MS is the most common non traumatic disease causing neurological sequelae in young adults, thus having a high social burden. Since there is a diffuse CNS involv

11. Auditory stimulation and cardiac autonomic regulation
Previous studies have already demonstrated that auditory stimulation with music influences the cardiovascular system. In this study, we described the relationship between musical auditory stimulation and heart rate variability. Searches were performed with the Medline, SciELO, Lilacs and Cochrane databases using the following keywords: "auditory stimulation"

12. Efeitos da estimulação transcraniana por corrente contínua sobre a variabilidade da freqüência cardíaca de mulheres hipertensas / Effects of transcranial direct current stimulation on heart rate variability of hypertensive women
A estimulação transcraniana por corrente contínua (ETCC) é uma técnica neuromodulatória capaz de modificar a excitabilidade cortical e supostamente modular a atividade neural de áreas corticais envolvidas na regulação autonômica, como o córtex pré-frontal medial (CPFM) e o córtex insular (CI). Com relação ao SNA, existem evidências de hiper-a
