Increased osmolality of conscious water-deprived rats supports arterial pressure and sympathetic activity via a brain action by Brooks, Virginia L, Qi, Yue, O'Donaughy, Theresa L

“…To test the hypothesis that high osmolality acts in the brain to chronically support mean arterial pressure (MAP) and lumbar sympathetic nerve activity (LSNA),…”

Acute and chronic increases in osmolality increase excitatory amino acid drive of the rostral ventrolateral medulla in rats by Brooks, Virginia L, Freeman, Korrina L, O'Donaughy, Theresa L

“…Water deprivation is associated with increased excitatory amino acid (EAA) drive of the rostral ventrolateral medulla (RVLM), but the mechanism is unknown…”

Endogenous carbon monoxide is an endothelial-derived vasodilator factor in the mesenteric circulation by Naik, Jay S, O'Donaughy, Theresa L, Walker, Benjimen R

“…Chronic hypoxia (CH) is associated with both blunted agonist-induced and myogenic vascular reactivity, possibly due to an enhanced production of heme oxygenase…”

NO and endogenous angiotensin II interact in the generation of renal sympathetic nerve activity in conscious rats by McKeogh, Donogh F, O'Donaughy, Theresa L, Brooks, Virginia L

“…Nitric oxide (NO) appears to inhibit sympathetic tone in anesthetized rats. However, whether NO tonically inhibits sympathetic outflow, or whether endogenous…”
