Key points We studied healthy astronauts before, during and after the Neurolab Space Shuttle mission with controlled breathing and apnoea, to identify autonomic changes that might contribute to postflight orthostatic intolerance. Measurements include

To determine whether physiological, rhythmic fluctuations of vagal baroreflex gain persist during exercise, post-exercise ischaemia and recovery.We studied responses of six supine healthy men and one woman to a stereotyped protocol comprising rest, h

Effects of Antecedent GABAA Activation With Alprazolam on Counterregulatory Responses to Hypoglycemia in Healthy Humans

Autor: Andrew C. Ertl, Maka S. Hedrington, Stephen N. Davis, Donna B. Tate, Stephnie Farmerie, Zhihui Wang

Publikováno v: Diabetes

OBJECTIVE To date, there are no data investigating the effects of GABAA activation on counterregulatory responses during repeated hypoglycemia in humans. The aim of this study was to determine the effects of prior GABAA activation using the benzodiaz

Effects of Acute Hypoglycemia on Inflammatory and Pro-atherothrombotic Biomarkers in Individuals With Type 1 Diabetes and Healthy Individuals

Autor: Vanessa J. Briscoe, Nino G. Joy, Donna B. Tate, Maka S. Hedrington, Stephen N. Davis, Andrew C. Ertl

Publikováno v: Diabetes Care

OBJECTIVE Recent large randomized trials have linked adverse cardiovascular and cerebrovascular events with hypoglycemia. However, the integrated physiological and vascular biological mechanisms occurring during hypoglycemia have not been extensively

Effects of Intensive Therapy and Antecedent Hypoglycemia on Counterregulatory Responses to Hypoglycemia in Type 2 Diabetes

Autor: Andrew C. Ertl, Stephen N. Davis, Vanessa J. Briscoe, Stephanie Mann, Donna B. Tate

Publikováno v: Diabetes. 58:701-709

OBJECTIVE—The physiology of counterregulatory responses during hypoglycemia in intensively treated type 2 diabetic subjects is largely unknown. Therefore, the specific aims of the study tested the hypothesis that 1) 6 months of intensive therapy to

Stimulation of both type I and type II corticosteroid receptors blunts counterregulatory responses to subsequent hypoglycemia in healthy man

Publikováno v: American Journal of Physiology-Endocrinology and Metabolism. 294:E506-E512

Antecedent increases of corticosteroids can blunt counterregulatory responses to subsequent stress. Our aim was to determine whether prior activation of type I corticosteroid (mineralocorticoid) or type II corticosteroid (glucocorticoid) receptors bl

Effects of the Selective Serotonin Reuptake Inhibitor Fluoxetine on Counterregulatory Responses to Hypoglycemia in Individuals With Type 1 Diabetes

Autor: Donna B. Tate, Stephen N. Davis, Andrew C. Ertl, Vanessa J. Briscoe

Publikováno v: Diabetes

OBJECTIVE—Previous work has demonstrated that chronic administration of the serotonin reuptake inhibitor (SSRI) fluoxetine augments counterregulatory responses to hypoglycemia in healthy humans. However, virtually no information exists regarding th

Effects of a Selective Serotonin Reuptake Inhibitor, Fluoxetine, on Counterregulatory Responses to Hypoglycemia in Healthy Individuals

Autor: Donna B. Tate, Stephen N. Davis, Vanessa J. Briscoe, Andrew C. Ertl, Sheila Dawling

Publikováno v: Diabetes

OBJECTIVE—Hypoglycemia commonly occurs in intensively-treated diabetic patients. Repeated hypoglycemia blunts counterregulatory responses, thereby increasing the risk for further hypoglycemic events. Currently, physiologic approaches to augment cou

Human cerebral autoregulation before, during and after spaceflight

Autor: Dwain L. Eckberg, Rong Zhang, William H. Cooke, Jay C. Buckey, Ken-ichi Iwasaki, Benjamin D. Levine, David Robertson, Andrew C. Ertl, C. Gunnar Blomqvist, James A. Pawelczyk, André Diedrich, Cole A. Giller, Italo Biaggioni, Chester A. Ray, James F. Cox, Lynda D. Lane, F. Baisch, Julie H. Zuckerman

Publikováno v: The Journal of Physiology. 579:799-810

Exposure to microgravity alters the distribution of body fluids and the degree of distension of cranial blood vessels, and these changes in turn may provoke structural remodelling and altered cerebral autoregulation. Impaired cerebral autoregulation

Autonomic Contribution to Blood Pressure and Metabolism in Obesity

Autor: Stephen N. Davis, André Diedrich, Italo Biaggioni, Cyndya A. Shibao, Kong Y. Chen, Sachin Y. Paranjape, Alfredo Gamboa, Andrew C. Ertl, Ginnie Farley, Daniel W. Byrne

Publikováno v: Hypertension. 49:27-33

Obesity is associated with alterations in the autonomic nervous system that may contribute to the increase in blood pressure and resting energy expenditure present in this condition. To test this hypothesis, we induced autonomic withdrawal with the g
