13. Heart disease and the stress hypothesis in the mid-twentieth century: a historical review
Abstract Background In the 1920s, heart disease (a noncommunicable disease), was the new leading cause of death in the USA. Simultaneously, experimental progress in the study of stress provided scientific justification for a new type of risk factor. The objective of the present work is to examine the history of heart disease as a public health problem and

14. Effect of selective β-adrenoceptor blockade and surgical resection of the celiac-superior mesenteric ganglion complex on delayed liquid gastric emptying induced by dipyrone, 4-aminoantipyrine, and antipyrine in rats
There is evidence for participation of peripheral β-adrenoceptors in delayed liquid gastric emptying (GE) induced in rats by dipyrone (Dp), 4-aminoantipyrine (AA), and antipyrine (At). The present study aimed to determine whether β-adrenoceptors are involved in delayed GE induced by phenylpyrazole derivatives and the role of the prevertebral sympathetic ne

15. Mediumship: review of quantitatives studies published in the 21st century
Abstract Background Mediumship can be defined as the alleged ability to communicate with deceased persons. The last decade has been particularly productive for this field of research and the study of mediumship can help the understanding of the human mind-brain relationship and provide objective data to the scientific community and to the general population

16. Effect of the systemic administration of methylprednisolone on the lungs of brain-dead donor rats undergoing pulmonary transplantation
OBJECTIVE: Most lung transplants are obtained from brain-dead donors. The physiopathology of brain death involves hemodynamics, the sympathetic nervous system, and inflammatory mechanisms. Administering methylprednisolone 60 min after inducing brain death in rats has been shown to modulate pulmonary inflammatory activity. Our objective was to evaluate the e

17. Nasal paraganglioma: a case report and literature review
INTRODUCTION: Paragangliomas are neuroendocrine tumors that most commonly originate in the adrenal gland, a type that is called pheochromocytoma; however, 5-10% of paragangliomas are extra-adrenal and may arise in any area between the neck and pelvic region along the sympathetic nervous system. Those located in the head and neck comprise 3% of extra-adrenal

18. Effect of cervical sympathetic block on cerebral vasospasm after subarachnoid hemorrhage in rabbits
PURPOSE: Cerebral vasospasm (CVS) is a major complication after subarachnoid hemorrhage (SAH) induced by the rupture of intracranial aneurysms. The aim of the present study was to investigate the effect and mechanism of cervical sympathetic block on cerebral vasospasm of the rabbits after SAH. METHODS: After successful modeling of cervical sympathetic block,

19. Importância do tecido adiposo marrom na ativação da termogênese induzida pela injeção central do C75, um inibidor da ácido graxo sintase / Importance of brown adipose tissue in the activation of thermogenesis induced by central injection of C75, a fatty acid synthase inhibitor
C75, a synthetic inhibitor of fatty acid synthase, causes anorexia and weight loss in rodents, but the underlying mechanisms are not totally known. Thus, the hypothesis tested in this work was that brown adipose tissue (BAT), an organ with important role for control of thermogenesis, could be involved in the anti-obesity effects of fatty acid synthase inhibi

20. 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

21. Efeito do avental branco na hipertensão resistente : participação da disfunção autonômica e lesões de órgãos alvo / White coat effect in resistant hypertension : evaluation of autonomic dysfunction and target organ damage
A definição de hipertensão arterial resistente (HAR) inclui pacientes cuja pressão arterial (PA) permanece acima da meta apesar do uso de 3 classes de anti-hipertensivos bem como aqueles que usam 4 ou mais classes e possuem pressão controlada, excluída a pseudo-resistência. A hiperatividade do sistema nervoso simpático está criticamente envolvida na

22. Avaliação do perfil da leptina plasmática na hipertensão arterial resistente / Evaluation of plasma leptin profile in resistant hypertension
A leptina, um hormônio derivado de adipócitos, e a aldosterona, têm sido associados aos mecanismos fisiopatológicos da hipertensão. Entretanto, apesar de estudos demonstrarem a associação da leptina com o espeçamento íntimo-carotídeo, distensibilidade arterial, ativação do sistema nervoso simpático, a relação entre os níveis plasmáticos de l

23. 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"

24. Efeito do tratamento com estradiol sobre o controle da pressão arterial e o estresse oxidativo
In this thesis was studied the sympathovagal and the nitric oxide (NO)/reactive oxygen species (ROS) balances in ovariectomized female rats. It was verified the effectiveness of 17b-estradiol in the blood pressure (BP) control and cardiovascular oxidative stress using low doses of estrogen. Then, we developed three protocols to evaluate morphometric, hemodyn
