1. Association of Anti-β1 and Anti-M2 Antibodies with Autonomic Nervous System Modulation in Patients with Chronic Chagas Cardiomyopathy
Abstract Background: Different immune mechanisms of myocardial damage involved in the pathophysiology of Chagas disease coexist with high titers of autoantibodies induced by T. cruzi . There are few studies in the literature about the adaptive role of anti-β1 and anti-M2 antibodies in chronic Chagas cardiomyopathy (CCC). Objectives: To evaluate the associ

2. Respostas autonômicas de recém-nascidos prematuros ao posicionamento do corpo e ruídos ambientais na unidade de terapia intensiva neonatal
RESUMO Objetivo: Avaliar as respostas fisiológicas e do sistema nervoso autônomo de recém-nascidos prematuros ao posicionamento do corpo e ruídos ambientais na unidade de terapia intensiva neonatal. Métodos: Este foi um estudo quasi-experimental. O sistema nervoso autônomo de recém-nascidos foi avaliado com base na variabilidade da frequência card�

3. Non-linear indices of heart rate variability during endodontic treatment
Abstract Dental treatment promotes psychosomatic change that can influence the procedure and compromise the general well-being of the patient. In this context, it highlights the importance of evaluating the function of the autonomic nervous system in individuals undergoing endodontic treatment. Thus, this manuscript aimed to analyse cardiac autonomic modulat

4. Vagotomy ameliorates islet morphofunction and body metabolic homeostasis in MSG-obese rats
The parasympathetic nervous system is important for β-cell secretion and mass regulation. Here, we characterized involvement of the vagus nerve in pancreatic β-cell morphofunctional regulation and body nutrient homeostasis in 90-day-old monosodium glutamate (MSG)-obese rats. Male newborn Wistar rats received MSG (4 g/kg body weight) or saline [control (CTL

5. Influence of resistance training on cardiac autonomic modulation: literature review
RESUMO Entre os benefícios promovidos pelo treinamento resistido, a sua influência sobre a modulação autonômica cardíaca nos chama a atenção, tendo em vista a importância do sistema nervoso autônomo (SNA) no controle das funções internas do organismo. O objetivo da presente revisão narrativa foi reunir informações a respeito dos efeitos do tr

6. Rastreamento em vídeo das características da pupila / Video tracking of pupil features
The study of the pupil s movements has signicant clinical interest because it acts as an objective indicator of retinal sensitivity to light and, consequently, of the optic nerve. Its permanent oscillation is the result of balance between opposing ows of the sympathetic and parasympathetic nervous system. The pupil s state of an individual allows the diagnos

7. Análise espectral de sinais atriais e sua correlação topográfica com a inervação parassimpática cardíaca / Spectral analysis of atrial signals and its topographic correlation with cardiac parassimpathetic innervation
Objetivo. Verificar se as características espectrais dos eletrogramas atriais (EgA) em ritmo sinusal (RS) se correlacionam com a presença de gânglios parassimpáticos cardíacos. Materiais e Resultados. Treze pacientes encaminhados para submeter-se a ablação de fibrilação atrial (FA) foram incluídos de forma prospectiva. Previamente ao início da abl

8. Acute electrophysiologic consequences of pyridostigmine inhibition of cholinesterase in humans
The cardiovascular electrophysiologic basis for the action of pyridostigmine, an acetylcholinesterase inhibitor, has not been investigated. The objective of the present study was to determine the cardiac electrophysiologic effects of a single dose of pyridostigmine bromide in an open-label, quasi-experimental protocol. Fifteen patients who had been indicated

9. Alterações cardiovasculares de fêmeas de ratos espontaneamente hipertensos (SHR) relacionadas com a idade / Cardiovascular changes in female spontaneously hypertensive rats (SHR) age-related
Hypertension is a major cause of cardiovascular disorders, and the natural progression of this disease may trigger further changes in the circulatory system. Experimental models are widely used in studies on the changes that occur in the cardiovascular system induced by hypertension. The SHR is the model that most closely matches the human hypertension, as i

10. Autonomic control of cardiorespiratory interactions in fish, amphibians and reptiles
Control of the heart rate and cardiorespiratory interactions (CRI) is predominantly parasympathetic in all jawed vertebrates, with the sympathetic nervous system having some influence in tetrapods. Respiratory sinus arrhythmia (RSA) has been described as a solely mammalian phenomenon but respiration-related beat-to-beat control of the heart has been describe

11. Effect of carotid and aortic baroreceptors on cardiopulmonary reflex: the role of autonomic function
We determined the sympathetic and parasympathetic control of heart rate (HR) and the sensitivity of the cardiopulmonary receptors after selective carotid and aortic denervation. We also investigated the participation of the autonomic nervous system in the Bezold-Jarish reflex after selective removal of aortic and carotid baroreceptors. Male Wistar rats (220-

12. Avaliação da função autonômica em portadores de cardiomiopatia hipertrófica com e sem síncope / Assessment of autonomic nervous function in patients with hypertrophic cardiomyopathy with and without syncope
BACKGROUND: Unexplained syncope is considered a risk factor for sudden death in hypertrophic cardiomyopathy (HCM). Several mechanisms are involved in its pathogenesis, including the difficulty in adaptation of the systemic vascular resistance to exertion and to orthostatic stress, which may be influenced by a dysfunction of the autonomic nervous system. The
