Time‐course analysis of cerebral circulation and cardiorespiratory responses to acute central blood volume reduction in healthy young males

open access: yesExperimental Physiology, EarlyView.
Abstract Central blood volume (CBV) reduction challenges circulatory and respiratory homeostasis, particularly during the initial compensatory phase (0–2 min), when rapid physiological adaptations occur. In this study, we examined dynamic cardiorespiratory responses to CBV reduction using lower‐body negative pressure (LBNP) in 11 healthy young males ...

Cost-Effectiveness of Advanced Imaging Technologies in the Presurgical Workup of Epilepsy. [PDF]

open access: yes, 2020
The cost-effectiveness and benefit of many diagnostic tests used in the presurgical evaluation for persons with epilepsy is for the most part uncertain as is their influence on decision-making.

Cerebral haemodynamic responses to inspiratory muscle work

open access: yesExperimental Physiology, EarlyView.
Abstract Fatiguing inspiratory work has been shown to evoke a sympathetically mediated reflex that has systemic cardiovascular consequences, including increases in heart rate and blood pressure and a decrease in resting limb vascular conductance. Moreover, the response to this reflex appears to be attenuated in females compared with males.

No difference in mean middle cerebral artery blood velocity responses between lower‐ and upper‐body unilateral resistance exercise in untrained individuals

open access: yesExperimental Physiology, EarlyView.
Abstract Dynamic resistance exercise (RE) produces sinusoidal fluctuations in blood pressure that are mirrored by middle cerebral artery blood velocity (MCAv). However, whether lower‐ or upper‐body RE elicits a differential cerebrovascular response has not yet been examined.

Sex differences in cerebral blood flow and cardiac function in response to exercise in the heat

open access: yesExperimental Physiology, EarlyView.
Abstract We investigated the effect of exercising in hot conditions on cerebral blood flow and systolic left ventricular (LV) function in males and females, to explore sex differences. The experimental condition consisted of walking on a treadmill at 5 km/h and 2% incline, inside a heat chamber at 40°C (50% relative humidity), for 90 min.

THROMBOLYTIC TREATMENT AND DRAMATIC IMPROVEMENT OF THE CLINICAL PICTURE IN A PATIENT WITH ACUTE OCCLUSION OF THE MIDDLE CEREBRAL ARTERY FOLLOWED BY TRANSCRANIAL DOPPLER SONOGRAPHY

open access: yesZdravniški Vestnik, 2004
Background. Thrombolytic treatment of ischemic cerebral stroke by means of a recombinant tissue plasminogen activator can be very successful in selected patients.

Intracranial hypertension influence on the cerebral blood flow in children with serous meningitis

open access: yesЖурнал инфектологии, 2014
Transcranial Doppler sonography was performed in 120 children with serous meningitis with various degrees of intracranial hypertension. Cerebral blood flow disturbances – decreased dilatation reserve and mean blood flow velocity in cerebral arteries ...

Effect of moderate altitude and nocturnal oxygen therapy on cerebrovascular function in patients with COPD: A randomized, crossover trial at 2048 m

open access: yesExperimental Physiology, EarlyView.
Abstract We investigated whether nocturnal oxygen therapy improves next‐day cerebrovascular function in lowlanders with chronic obstructive pulmonary disease (COPD) staying at moderate altitude. This randomized, placebo‐controlled single‐blind crossover trial was performed in moderate‐to‐severe COPD patients [forced expiratory volume in 1 s (FEV1 ...

Bilateral dynamic cerebral autoregulation assessment during endovascular treatment in large‐vessel occlusion stroke

open access: yesExperimental Physiology, EarlyView.
Abstract Recanalization by endovascular treatment (EVT) is effective in acute ischaemic stroke caused by large‐vessel occlusion. Better understanding of the pathophysiology could possibly identify targets for improving peri‐procedural management and thereby patient outcome.
