Via developmental programming, prenatal perturbations, such as exposure to glucocorticoids and maternal malnutrition alter kidney development and contribute to the development of hypertension. To examine the possibility that alterations in tubuloglomerular feedback (TGF) contribute to the development of hypertension in

Central CO2-chemosensitive neurons in the caudal solitary complex (cSC) are stimulated not only by hypercapnic acidosis, but by hyperoxia as well. While a cellular mechanism for the CO2 response has yet to be isolated, previous data show that a redox-sensitive

Experiments have shown that hyperbaric oxygen (HBO2) therapy reduces cyanide-induced cerebral distress. The exact mechanism behind HBO2's neuroprotective effect is unknown, but has been proposed to be mediated by an increased neuronal nitric oxide (NO) bioavailability, which may compete with

The poly(ADP-ribose) polymerase (PARP) inhibitor PJ34 has been reported to improve endothelial dysfunction in the peripheral system. We addressed the role of PJ34 on the vascular tone and vasoreactivity during development in the mouse brain. Blood flows were measured in

Nitric oxide (NO) is a recently discovered and highly unorthodox messenger molecule. Current evidence indicates that, in the CNS, NO is produced enzymatically in postsynaptic structures in response to activation of excitatory amino acid receptors. It then diffuses out to
