Investigação do envolvimento de subtipos de adrenoceptores α1 no efeito anti-imobilidade da imipramina no teste de suspensão pela cauda
(Universidade Estadual Paulista (Unesp), 2015)
Dietary Fructose Increases the Sensitivity of Proximal Tubules to Angiotensin II in Rats Fed High-Salt Diets
(Multidisciplinary Digital Publishing Institute, 2018-09)
Dietary fructose causes salt-sensitive hypertension. Proximal tubules (PTs) reabsorb 70% of the filtered NaCl. Angiotensin II (Ang II), atrial natriuretic peptide (ANP) and norepinephrine (NE) regulate this process. Although ...
Neuromodulatory role of angiotensin-(1-7) in the central nervous system
(Portland Press, 2013-07-01)
Ang-(1–7) [angiotensin-(1–7)] constitutes an important functional end-product of the RAS (renin–angiotensin system) endogenously formed from AngI (angiotensin I) or AngII (angiotensin II) through the catalytic activity of ...
Purification and characterization of the active form of tyrosine hydroxylase from mesangial cells in culture
(Wiley-Blackwell, 2002-01-01)
The capacity of mesangial cells (MC) to produce catecholamines (CAs) has been investigated in our laboratory. To study the CA cascade, it is necessary to examine some steps in their metabolic pathway. Tyrosine hydroxylase ...
Effects of chronic modafinil treatment in young rats on social behavior and dopaminergic neurotransmission
(Universidad de Valparaíso, 2020-11)
Modafinil (MOD) is an atypical stimulant used to enhance wakefulness and vigilance. The mechanism of action of MOD includes the blockage of dopamine (DA) and norepinephrine (NE) transporters (DAT and NET, respectively). ...
Effects of catecholamines on secretion of interferon tau and expression of genes for synthesis of polyamines and apoptosis by ovine trophectoderm
(2018)
Ovine trophectoderm (oTr1) cells were used to investigate effects of epinephrine (EP), norepinephrine (NE), and dopamine (DA) on their proliferation, migration and adhesion, secretion of interferon tau (IFNT), and expression ...
Dopamine-dependent iron toxicity in cells derived from rat hypothalamus
(AMER CHEMICAL SOC, 2005-03)
We report a new and specific mechanism for iron-mediated neurotoxicity using RCHT cells, which were derived from rat hypothalamus. RCHT cells exhibit immunofluorescent-positive markers for dopamine beta-hydroxylase and the ...
Efectos agudos de la restricción, choque y entrenamiento en el laberinto elevado en T en los sistemas de noradrenalina y serotonina en la corteza prefrontal.
(Universidad Católica de Colombia, 2014-07-01)
La corteza prefrontal (CPF) participa en las funciones cognitivas y la regulación del estrés. Las concentraciones de noradrenalina (NA) y serotonina (5-HT) en algunas regiones en el sistema nervioso central son modificadas ...
Estresse e periodontite: avaliação da inervação simpática no periodonto e da resposta adrenérgica após infecção por Porphyromonas gingivalis
(Universidade Estadual Paulista (Unesp), 2022-01-25)
O estresse agrava a doença periodontal por vários mecanismos, sendo a estimulação do sistema nervoso simpático (SNS) um deles. A literatura mostra que a estimulação de receptores β-adrenérgicos (β-AR) aumenta a angiogênese ...
