    • Alterations in the central vasopressin and oxytocin axis after lesion of a brain osmotic sensory region 

      Oliveira, G. R.; Franci, C. R.; Rodovalho, G. V.; Franci, JAA; Morris, M.; Rocha, MJA (Elsevier B.V., 2004-07-15)
      The anteroventral region of the third ventricle (AV3V) is critical in mediating osmotic sensitivity. AV3V lesions increase plasma osmolality and block osmotic-induced vasopressin (VP) and oxytocin (OT) secretion. the aim ...

    • Angiotensin I-converting enzyme (ACE) activity and expression in rat central nervous system after sleep deprivation 

      Visniauskas, Bruna [UNIFESP]; Oliveira, Vitor [UNIFESP]; Carmona, Adriana K. [UNIFESP]; D'Almeida, Vania [UNIFESP]; Melo, Robson L. de; Tufik, Sergio [UNIFESP]; Chagas, Jair R. [UNIFESP] (Walter de Gruyter & Co, 2011-04-01)
      Proteases are essential either for the release of neuropeptides from active or inactive proteins or for their inactivation. Neuropeptides have a fundamental role in sleep-wake cycle regulation and their actions are also ...

    • AV3V lesions reduce the pressor response to L-glutamate into the RVLM 

      Vieira, A. A.; Colombari, E.; De Luca, L. A.; Colombari, DSD; Menani, J. V. (Elsevier B.V., 2006-05-01)
      Neurons from the rostral ventrolateral medulla (RVLM) directly activate sympathetic preganglionic neurons in the spinal cord. Hypertensive responses and sympathetic activation produced by different stimuli are strongly ...

    • Cardiovascular responses to microinjection of L-glutamate into the NTS in AV3V-lesioned rats 

      Vieira, A. A.; Colombari, E.; De Luca, L. A.; Colombari, DSD; Menani, J. V. (Elsevier B.V., 2004-10-29)
      The excitatory amino acid L-glutamate injected into the nucleus of the solitary tract (NTS) in unanesthetized rats similar to peripheral chemoreceptor activation increases mean arterial pressure (MAP) and reduces heart ...

    • Central cholinergic blockade reduces the pressor response to L-glutamate into the rostral ventrolateral medullary pressor area 

      Antonio Vieira, Alexandre; Colombari, Eduardo; De Luca, Laurival A.; Almeida Colombari, Debora Simoes de; Menani, Jose V. (Elsevier B.V., 2007-06-25)
      Injections of the excitatory amino acid L-glutamate (L-glu) into the rostral ventrolateral medulla (RVLM) directly activate the sympathetic nervous system and increase mean arterial pressure (MAP). A previous study showed ...

    • Craniopharyngiomas: intratumoral chemotherapy with interferon-alpha: a multicenter preliminary study with 60 cases 

      Cavalheiro, Sergio [UNIFESP]; Di Rocco, Concezzio; Valenzuela, Sergio; Dastoli, Patricia A. [UNIFESP]; Tamburrini, Gianpiero; Massimi, Lucca; Nicacio, Jardel M. [UNIFESP]; Faquini, Igor V. [UNIFESP]; Ierardi, Daniela F. [UNIFESP]; Silva, Nasjla Saba [UNIFESP]; Pettorini, Benedetta Ludovica; Toledo, Silvia Regina Caminada de [UNIFESP] (Amer Assoc Neurological Surgeons, 2010-04-01)
      Object. the authors assessed the efficacy of intratumoral interferon-alpha (IFN alpha)-based chemotherapy in pediatric patients with cystic craniopharyngiomas.Methods. in a prospective multicenter study of 60 pediatric ...

    • Differential control of cardiac functions by the brain 

      Salo, Lauren M.; Campos, Ruy R.; McAllen, Robin M. (Blackwell Publishing, 2006-12-01)
      1. the idea is introduced that cardiac rate, contractility or atrioventricular (A-V) conduction spread may be controlled independently by the brain. Limited data from reflex studies are cited to support this view.2. Evidence ...

    • Disruption of light-induced c-Fos immunoreactivity in the suprachiasmatic nuclei of chronic epileptic rats 

      Sanabria, ERG; Scorza, F. A.; Bortolotto, Z. A.; Calderazzo, L. S.; Cavalheiro, E. A. (Elsevier B.V., 1996-09-27)
      Photic stimulation during specific day periods may induce Fos oncoprotein expression within the ventrolateral part of the suprachiasmatic nucleus (SCN) in the hypothalamus of rodents. This phenomenon appears to be a major ...

    • Effect of chemical stimulation of the dorsomedial hypothalamic nucleus on blood plasma glucose, triglycerides and free fatty acids in rats 

      Zaia, CTBV; Gaziri, LCJ; Zaia, DAM; Delattre, E.; Dolnikoff, M. S.; TimoIaria, C. (Elsevier B.V., 1997-01-01)
      The effects of chemical stimulation of the dorsomedial hypothalamic nucleus (DMH) on blood plasma concentration of glucose, triglycerides, insulin, and free fatty acids (FFA) were investigated in anesthetized adult Wistar ...

    • Evidence for a role of nitric oxide in hindlimb vasodilation induced by hypothalamic stimulation in anesthetized rats 

      Ferreira-neto, Marcos L. [UNIFESP]; Possas, Olga S. [UNIFESP]; Lopes, Oswaldo Ubriaco [UNIFESP]; Cravo, Sergio Luiz [UNIFESP] (Academia Brasileira de Ciências, 2005-06-01)
      Electrical stimulation of the hypothalamus produces cardiovascular adjustments consisting of hypertension, tachycardia, visceral vasoconstriction and hindlimb vasodilation. Previous studies have demonstrated that hindlimb ...
