Journal ArticleDOI
Estimation of energy expenditure by a portable accelerometer.
Henry J. Montoye,Richard A. Washburn,Stephen B. Servais,Andrew C. Ertl,John G. Webster,F. J. Nagle +5 more
TL;DR: A small portable accelerometer was developed to estimate the energy expenditure of daily activities and is reported to be an improvement over movement counters currently on the market.
Journal ArticleDOI
Effects of Acute Hypoglycemia on Inflammatory and Pro-atherothrombotic Biomarkers in Individuals With Type 1 Diabetes and Healthy Individuals
Nino G. Joy,Maka S. Hedrington,Vanessa J. Briscoe,Donna B. Tate,Andrew C. Ertl,Stephen N. Davis +5 more
TL;DR: It is concluded that acute hypoglycemia can result in complex vascular effects including activation of prothrombotic, proinflammatory, and pro-atherogenic mechanisms in individuals with type 1 diabetes and healthy individuals.
Journal ArticleDOI
Human muscle sympathetic neural and haemodynamic responses to tilt following spaceflight.
Benjamin D. Levine,James A. Pawelczyk,Andrew C. Ertl,Andrew C. Ertl,James F. Cox,Julie H. Zuckerman,André Diedrich,Italo Biaggioni,Chester A. Ray,Michael L. Smith,Satoshi Iwase,Mitsuru Saito,Yoshiki Sugiyama,Tadaaki Mano,Rong Zhang,Ken-ichi Iwasaki,Lynda D. Lane,Jay C. Buckey,William H. Cooke,F. Baisch,David Robertson,Dwain L. Eckberg,C. Gunnar Blomqvist +22 more
TL;DR: It is concluded that after 16 days of spaceflight, muscle sympathetic nerve responses to upright tilt are normal, and left ventricular stroke volume and Muscle sympathetic nerve activity suggested that sympathetic responses were appropriate for the haemodynamic challenge of upright tilt and were unaffected by spaceflight.
Journal ArticleDOI
Hypovolemia in syncope and orthostatic intolerance role of the renin-angiotensin system
Giris Jacob,David Robertson,Rogelio Mosqueda-Garcia,Andrew C. Ertl,Rose Marie Robertson,Italo Biaggioni +5 more
TL;DR: The hypothesis that reduced plasma renin activity, perhaps from defects in sympathetic innervation of the kidney, could underlie a hypovolemia, giving rise to clinical symptoms of orthostatic intolerance is tested.
Journal ArticleDOI
Human muscle sympathetic nerve activity and plasma noradrenaline kinetics in space
Andrew C. Ertl,Andrew C. Ertl,André Diedrich,Italo Biaggioni,Benjamin D. Levine,Rose Marie Robertson,James F. Cox,Julie H. Zuckerman,James A. Pawelczyk,Chester A. Ray,Jay C. Buckey,Lynda D. Lane,Richard Shiavi,F. Andrew Gaffney,Fernando Costa,Carol Holt,C. Gunnar Blomqvist,Dwain L. Eckberg,F. Baisch,David Robertson +19 more
TL;DR: In space, baseline sympathetic neural outflow is increased moderately and sympathetic responses to lower body suction are exaggerated, and notwithstanding hypovolaemia, astronauts respond normally to simulated orthostatic stress and are able to maintain their arterial pressures at normal levels.
