Novo dispositivo de medida de rigidez arterial - pOpmètri® e suas correlações com análises morfométricas e densidade de colágeno em artérias de ratos de diferentes idades
(Universidade Federal de São Carlos, 2018-03-16)
Arterial stiffness measurement, evaluated by pulse wave velocity (PWV), is a predictor of cardiovascular events. Among the main factors that affect arterial stiffness are cross-sectional area, medial wall thickening, ...
Análise temporal dos efeitos preventivos do exercício resistido sobre a atrofia muscular induzida por dexametasona
(Universidade Federal de São Carlos, 2018-03-27)
Synthetic glucocorticoids have potent anti-inflammatory and immunosuppressive action, though its chronic usage can trigger muscle atrophy. On the other hand the resistance training (RT) acts in opposition to atrophic ...
Papel do córtex pré-frontal medial na ansiogênese induzida pelo estresse de derrota social em camundongos
(Universidade Federal de São Carlos, 2018-10-18)
Recent findings have demonstrated that the medial prefrontal cortex (mPFC) has a lateralized role in the control of response to stressors, and the left hemisphere (LmPFC) would attenuate the anxiogenic responses elicited ...
O bloqueio dos receptores glicocorticóides da região infralímbica do córtex pré-frontal medial facilita a aquisição, mas não a consolidação da memória de camundongos submetidos ao protocolo de teste e reteste no labirinto em cruz elevado
(Universidade Federal de São Carlos, 2018-09-21)
A single experience (test) in the elevated plus maze (EPM) increases the avoidance of open arms and impairs the anxiolytic efficacy of the midazolam benzodiazepine agonist (MDZ) in a subsequent re-esposition (retest). ...
