Time-dependent effects of low-dose aspirin on plasma renin activity, aldosterone, cortisol, and catecholamines.

3 Oct 2009 Studies have shown that aspirin may decrease blood pressure when given at bedtime but not when administered on awakening. However, until now, a biologically plausible mechanism of this striking phenomenon was not revealed. We investigated the effect ... Read more...

Parallel preoptic pathways for thermoregulation.

21 Sep 2009 Sympathetic premotor neurons in the rostral medullary raphe (RMR) regulate heat conservation by tail artery vasoconstriction and brown adipose tissue thermogenesis. These neurons are a critical relay in the pathway that increases body temperature. ... Read more...

Differential regulation of the central neural cardiorespiratory system by metabotropic neurotransmitters.

10 Sep 2009 Central neurons in the brainstem and spinal cord are essential for the maintenance of sympathetic tone, the integration of responses to the activation of reflexes and central commands, and the generation of an appropriate respiratory motor output. ... Read more...
