    • Adrenoceptors and Adaptive Mechanisms in the Heart during Stress 

      Spadari-Bratfisch, Regina Celia [UNIFESP]; Santos, Iraides Nunes dos; Kvetnansky, R.; Aguilera, G.; Goldstein, D.; Jezova, D.; Krizanova, O.; Sabban, E. L.; Pacak, K. (Blackwell Publishing, 2008-01-01)
      Several cardiovascular disorders have been related to alterations in beta-adrenoceptor (beta-AR) signaling at or beyond the receptor level. During the stress reaction, the sympathetic-adrenal medullary system and the ...

    • Long-term nitric oxide deficiency causes muscarinic supersensitivity and reduces beta(3)-adrenoceptor-mediated relaxation, causing rat detrusor overactivity 

      Monica, F. Z. T.; Bricola, A. A. O.; Bau, F. R.; Freitas, L. L. Lopes; Teixeira, S. A.; Muscara, M. N.; Abdalla, F. M. F.; Porto, Catarina Segretti [UNIFESP]; De Nucci, G.; Zanesco, A.; Antunes, E. (Nature Publishing Group, 2008-04-01)
      Background and purpose: Overactive bladder is a complex and widely prevalent condition, but little is known about its physiopathology. We have carried out morphological, biochemical and functional assays to investigate the ...

    • Rapid eye movement sleep deprivation-induced down-regulation of beta-adrenergic receptors in the rat brainstem and hippocampus 

      Pedrazzoli, M.; Venditti, Marco Antonio Campana [UNIFESP] (Elsevier B.V., 2004-09-01)
      Rapid eye movement (REM) sleep deprivation induces a cortical down-regulation of beta-adrenergic receptors. Down-regulation of cortical beta-adrenergic receptors is consistently observed after a number of different chronic ...

    • Stress and cardiac beta adrenoceptors 

      Santos, Iraides N.; Spadari-Bratfisch, Regina Celia [UNIFESP] (Taylor & Francis Ltd, 2006-06-01)
      Most modern theories about stress recognize that although stress is not a disease, it may be the trigger for the majority of diseases when allostatic overload has been generated. During stress, the glucocorticoids and ...

    • Thyroid hormone interacts with the sympathetic nervous system to modulate bone mass and structure in young adult mice 

      Fonseca, Tatiana L.; Teixeira, Marilia B. C. G.; Rodrigues-Miranda, Manuela; Silva, Marcos V.; Martins, Gisele M.; Costa, Cristiane C.; Arita, Danielle Y. [UNIFESP]; Perez, Juliana D. [UNIFESP]; Casarini, Dulce E. [UNIFESP]; Brum, Patricia C.; Gouveia, Cecilia H. A. (Amer Physiological Soc, 2014-08-15)
      To investigate whether thyroid hormone (TH) interacts with the sympathetic nervous system (SNS) to modulate bone mass and structure, we studied the effects of daily T-3 treatment in a supraphysiological dose for 12 wk on ...
