Brain strain: Blood flow and metabolism in environmental extremes

open access: yesExperimental Physiology, EarlyView.
Abstract This narrative review compares and contrasts the most commonly encountered environmental stressors on human cerebrovascular functioning. From high altitude and space, extreme apnoea, heat and cold stress, the impact of these stressors on the regulation of cerebral blood flow (CBF) and oxygen metabolism (CMRO2${\mathrm{CM}}{{\mathrm{R}}_ ...

Effect of repeated hot water immersion on cognitive performance, cerebrovascular function, sleep and biomarkers of neurodegeneration in older adults

open access: yesExperimental Physiology, EarlyView.
Abstract Ageing is associated with cognitive decline and increased risk of developing neurodegenerative disease. Repeated passive heating, using hot water immersion (HWI), may improve cognitive performance via improved cerebral oxygenation, but this is yet to be examined in older adults.

Stimulated Acoustic Emission Detected by Transcranial Color Doppler Ultrasound

open access: yes, 2000
Background and Purpose —Experimental and clinical data suggest that insonation of echo-contrast agents with high acoustical power produces disintegration of microbubbles, resulting in a pseudo-Doppler phenomenon called stimulated

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 ...

Stroke neurovascular responses to exercise: A novel rehabilitation paradigm

open access: yesExperimental Physiology, EarlyView.
Abstract Stroke is a leading cause of long‐term disability, impacting the cerebrovascular, peripheral vascular and neuromotor systems. Characterising vascular responses to exercise post‐stroke offers valuable insights into the impairments that might influence outcomes during neurorehabilitation.

Heparin and air filters reduce embolic events caused by intra-arterial cerebral angiography - A prospective, randomized trial

open access: yes, 2004
Background-Intra-arterial cerebral angiography is associated with a low risk for neurological complications, but clinically silent ischemic events after angiography have been seen in a substantial number of patients.Methods and Results-In a prospective ...

Translational perspectives on neurophysiological responses and mechanisms in blood flow restriction exercise

open access: yesExperimental Physiology, EarlyView.
Abstract Maintaining corticospinal tract function is crucial for voluntary movement. Exercise using high external loads/intensities is a promising intervention to promote adaptations to the corticospinal tract and improve physical function; however, such loads/intensities may not be tolerable or safe in populations with neurological disorders, motor ...

Transcranial doppler for carotid endarterectomy

open access: yesEuropean Journal of Vascular and Endovascular Surgery, 1996
Patients with symptomatic high-grade carotid artery stenosis benefit from carotid endarterectomy. However, the operation is not without complications. The perioperative stroke rate varies from 2 to as much as 24% and depends on technique and patient selection. Seventy percent of perioperative strokes occur during the operation and are equally caused by
