Background— This study tested the hypothesis that sympathetic nerve activity is increased
in pulmonary artery hypertension (PAH), a rare disease of poor prognosis and incompletely …

Adderall, consisting of a mixture of amphetamine salts and dextroamphetamine salts, is a
prescription drug for attention deficit/hyperactivity disorder (ADHD) and narcolepsy. Labeled or …

Rationale: The sympathetic nervous system has been reported to be activated in pulmonary
arterial hypertension (PAH). Objectives: We investigated the prognostic significance of …

Objectives : We assessed the effects of beta-adrenergic agonism on muscle sympathetic
nerve activity (MSNA) in patients with congestive heart failure (CHF) and young and matched …

The long-term effects of hemodialysis arteriovenous fistula (AVF) closure on left ventricular (LV)
morphology are unknown. Using echocardiography, we prospectively studied 17 kidney …

Background We have reported previously that the sympathetic nervous system is activated
in patients with pulmonary arterial hypertension (PAH), and that this is only partly explained …

To investigate the effects of muscle metaboreceptor activation during hypoxic static exercise,
we recorded muscle sympathetic nerve activity (MSNA), heart rate, blood pressure, …

Background. The acute bradycardia induced by the occlusion of an arteriovenous fistula (AVF),
known as the Nicoladoni-Branham sign, is considerably larger than that which occurs …

β-Adrenergic agonists may increase chemosensitivity in humans. We tested the hypothesis
that the β 1 -agonist dobutamine increases peripheral chemosensitivity in a double-blind …

Aims β‐adrenergic agonists increase peripheral chemoreceptor sensitivity in humans. We
tested the hypothesis that β 1 ‐agonist‐related increase in peripheral chemoreflex sensitivity …
