    • Abnormal heart rate recovery and deficient chronotropic response after submaximal exercise in young Marfan syndrome patients 

      Peres, Paulo Alberto Tayar [UNIFESP]; Carvalho, Antonio Carlos [UNIFESP]; Perez, Ana Beatriz Alvarez [UNIFESP]; Medeiros, Wladimir Musetti [UNIFESP] (Cambridge Univ Press, 2016)
      Background: Marfan syndrome patients present important cardiac structural changes, ventricular dysfunction, and electrocardiographic changes. An abnormal heart rate response during or after exercise is an independent ...

    • Análise fractal da variabilidade da frequência cardíaca em pacientes com HIV-AIDS e síndrome da lipodistrofia 

      Oliveira, Fernando Rocha [UNIFESP] (Universidade Federal de São Paulo (UNIFESP), 2015-09-30)
      Background: Lipodystrophy syndrome in people living with HIV / AIDS is characterized by change in disposal of body fat with metabolic changes associated with the use of antiretroviral therapy. These changes are characteristic ...

    • Caracterização da Modulação Autonômica Cardíaca e do Perfil Funcional de pessoas com Distrofia Muscular de Duchenne 

      Silva, Talita Dias da [UNIFESP] (Universidade Federal de São Paulo (UNIFESP), 2016-10-17)
      Among Muscular Dystrophies, Duchenne muscular dystrophy (DMD) is the most common genetic neuromuscular disease. Abnormal autonomic signaling is increasingly recognized as an important symptom in neuromuscular diseases, ...

    • Cardiac safety of repetitive transcranial magnetic stimulation in bulimic eating disorders 

      Van den Eynde, Frederique; Claudino, Angelica M. [UNIFESP]; Campbell, Iain; Horrell, Linda; Andiappan, Manoharan; Stahl, Daniel; Schmidt, Ulrike (Elsevier B.V., 2011-04-01)
      BackgroundRepetitive transcranial magnetic stimulation (rTMS) is increasingly used in research. However, cardiac safety is not routinely assessed.ObjectiveThis study aims to investigate cardiac safety of rTMS in people ...

    • Cardiopulmonary reflex is attenuated in iron overload conscious rats 

      Cardoso, Leonardo Maximo; Fernandes, Luciano Goncalves; Alves, Arthur Moreira; Pedrosa, Maria Lucia; Silva, Marcelo Eustaquio; Colombari, Eduardo; Dutra Moraes, Marcio Flavio; Chianca, Deoclecio Alves (Taylor & Francis Ltd, 2007-01-01)
      Increased iron intake can lead to iron accumulation in serum and tissues. Its has been described that serum and tissue iron overload increase reactive oxygen species (ROS) levels and reduce the effectiveness of the ...

    • Cardiovascular autonomic control in mice lacking angiotensin AT1a receptors 

      Chen, Yan Fang; Joaquim, Luis F.; Farah, Vera M.; Wichi, Rogerio B. [UNIFESP]; Razan Junior, Rubens; Salgado, Helio C.; Morris, Mariana (Amer Physiological Soc, 2005-04-01)
      Studies examined the role of angiotensin (ANG) AT1a receptors in cardiovascular autonomic control by measuring arterial pressure (AP) and heart rate (HR) variability and the effect of autonomic blockade in mice lacking ...

    • Cardiovascular function alterations induced by acute paradoxical sleep deprivation in rats 

      Almeida, F. R. [UNIFESP]; Perry, J. C. [UNIFESP]; Futuro-Neto, H. A.; Almeida, V. R. [UNIFESP]; Sebastiao, R. M. [UNIFESP]; Andersen, M. L. [UNIFESP]; Tufik, Sergio [UNIFESP]; Campos, R. R. [UNIFESP]; Bergamaschi, C. T. [UNIFESP] (Informa Healthcare, 2014-01-01)
      Sleep loss has been implicated in triggering the hypertension. the goal of the present study was investigated the possible mechanisms underlying cardiovascular alterations after acute paradoxical sleep deprivation (PSD). ...

    • Cardiovascular responses produced by central injection of hydrogen peroxide in conscious rats 

      Cardoso, Leonardo Maximo; Colombari, Debora Simoes de Almeida; Menani, Jose Vanderlei; Chianca, Deoclecio Alves; Colombari, Eduardo (Elsevier B.V., 2006-12-11)
      Reactive oxygen species (ROS) have been shown to modulate neuronal synaptic transmission and may play a role on the autonomic control of the cardiovascular system. in this study we investigated the effects produced by ...

    • Cardiovascular responses to hydrogen peroxide into the nucleus tractus solitarius 

      Cardoso, Leonardo Maximo [UNIFESP]; Almeida Colombari, Debora Simoes de; Menani, Jose V.; Toney, Glenn M.; Chianca, Deoclecio Alves; Colombari, Eduardo [UNIFESP] (Amer Physiological Soc, 2009-08-01)

    • Cardiovascular responses to substance P in the nucleus tractus solitarii: microinjection study in conscious rats 

      Abdala, Ana Paula Lima [UNIFESP]; Haibara, A. S.; Colombari, Eduardo [UNIFESP] (Amer Physiological Soc, 2003-08-01)
      The cardiovascular effects of substance P (SP) microinjections in the nucleus tractus solitarii (NTS) were evaluated in conscious rats. We chose this model because it is an effective way to access some of the cardiovascular ...
