Cerebrovascular reactivity (CVR) magnetic resonance imaging (MRI) probes cerebral
haemodynamic changes in response to a vasodilatory stimulus. CVR closely relates to the …

Cerebrovascular reactivity (CVR) is defined as the ability of vessels to alter their caliber in
response to vasoactive factors, by means of dilating or constricting, in order to increase or …

Background Posterior circulation and anterior circulation strokes share many clinical,
pathogenetic and radiological features, although some clinical signs are highly specific to …

This study was designed to investigate the acute effects of nonnicotinized e-cigarette (e-cig)
aerosol inhalation in nonsmokers both in terms of blood-based markers of inflammation and …

Cerebrovascular reactivity (CVR), defined here as the Blood Oxygenation Level Dependent
(BOLD) response to a CO 2 pressure change, is a useful metric of cerebrovascular function …

Altered cerebral perfusion has been reported in obstructive sleep apnea (OSA). Using
dynamic susceptibility contrast MRI, we compared cerebral perfusion between male OSA …

Although molecular design strategies for highly bright near-infrared II (NIR-II) fluorophores
were proposed, the lack of solid structural identification (single crystal) hinders the further …

Objective To examine the relationship between polysomnography-classified obstructive
sleep apnea (OSA) severity and cognitive performance in acute moderate-to-severe …

During slow-wave sleep, synaptic transmissions are reduced with a concomitant reduction in
brain energy consumption. We used 3 Tesla MRI to noninvasively quantify changes in the …

Patients with obstructive sleep apnea (OSA) are at elevated risk of developing systemic
vascular disease and cognitive dysfunction. Here, cerebral oxygen metabolism was …
