Acute ketone monoester ingestion lowers resting cerebral blood flow: a randomized cross‐over trial

The Journal of Physiology, EarlyView.
Abstract figure legend This double‐blind, placebo‐controlled, randomized cross‐over trial investigated the effects of ketone monoester (KME) ingestion on resting cerebral blood flow (CBF) in young adults. We demonstrate that KME supplementation lowers CBF in a dose‐dependent manner over 2‐houra post‐ingestion, whereas CBF remained unchanged following ...

Acute exposure to mobile phone and assessment of internal cerebral circulation in young healthy subjects : a transcranial Doppler study [PDF]

, 2012
International audienceThe rapid worldwide increase in the use of mobile phones raises questions about the possible adverse effects of RF fields emitted by these devices. The temporal lobe of brain is closest to the mobile phone.

The role of acid‐base balance in cerebrovascular and ventilatory responses to CO2 during 10 h normobaric hypoxia

The Journal of Physiology, EarlyView.
Abstract figure legend During 10 h exposures to normobaric hypoxia exposure there was a selective leftward shift in ventilatory response to hyperoxic hypercapnic rebreathing, but not the cerebrovascular response. The key findings are that the resetting of the central chemoreflex to lower PCO2${P_{{\mathrm{C}}{{\mathrm{O}}_2}}}$ during early hypoxic ...

Cerebrovascular ultrasonography: Technique and common pitfalls

Annals of Indian Academy of Neurology, 2013
Although the clinical features in some patients with cerebrovascular ischemia may be ill defined, majority of the patients present with focal neurological deficits caused by an arterial occlusion, and the clinical presentations are usually referable to ...

Arterial–venous differences of brain‐derived neurotrophic factor isoforms across the brain and muscle after exercise at different intensities

The Journal of Physiology, EarlyView.
Abstract figure legend Exercise‐induced increases in forearm venous plasma and serum brain‐derived neurotrophic factor (BDNF) are often assumed to be indicative of release from the brain. Sixteen healthy and physically fit adults (20–40 years old) were recruited to investigate whether exercise‐induced changes in forearm venous mature BDNF (mBDNF) and ...

Transcranial brain parenchyma sonography in movement disorders

Chinese Journal of Contemporary Neurology and Neurosurgery, 2012
The diagnosis and discrimination of movement disorders is very difficult in clinical medicine. We usually make a diagnosis according to symptoms and physical examination when the disease develops to a certain stage, but with few objective criteria ...

Ventilatory and cerebrovascular responses to exercise in lowlander children acclimatizing to high‐altitude

The Journal of Physiology, EarlyView.
Abstract figure legend To investigate age‐related differences in ventilatory and cerebrovascular responses to exercise at high‐altitude, adults (n = 10, 23–44 years) and children (n = 8, 7–14 years) completed progressive cycling exercise tests at sea‐level and following 6 days of acclimatization at 3800 m.

Optimization of pseudo‐continuous arterial spin labeling for brain perfusion imaging in the intraoperative setting

Magnetic Resonance in Medicine, Volume 95, Issue 2, Page 1123-1134, February 2026.
Abstract Purpose Pseudo‐continuous arterial spin labeling (PCASL) efficiency during intraoperative MRI is degraded due to large field inhomogeneities observed in some patients and lower arterial blood velocities induced by anesthesia. The purpose of this work was to maximize labeling efficiency during intraoperative MRI by optimizing PCASL parameters ...

Precision Diagnostics in Sports‐Related Traumatic Brain Injury: Pathophysiology, Biomarker Development and Emerging Technologies

Advanced Sensor Research, Volume 4, Issue 12, December 2025.
Sports‐related traumatic brain injuries (TBIs) remain underdiagnosed, within amateur athletic cohorts. This review critically synthesises recent advancements in AI‐assisted neuroimaging, blood‐based biomarker profiling, wearable biosensing platforms for early detection, injury stratification, and longitudinal surveillance of TBIs.
