Fetal Cerebral Blood Flow (Dys)autoregulation [PDF]

open access: yesDiagnostics
Background: As an extremely sensitive organ, particularly during in utero development, the brain has intrinsic systems to reduce the risk of cerebral damage in cases of insult, such as energy deprivation, due to a mechanism of positive balance in ...

Nimodipine augments cerebrovascular reactivity in aging but runs the risk of local perfusion reduction in acute cerebral ischemia

open access: yesFrontiers in Aging Neuroscience, 2023
IntroductionThe efficacy of cerebrovascular reactivity (CVR) is taken as an indicator of cerebrovascular health.Methods and ResultsWe found that CVR tested with the inhalation of 10 % CO2 declined in the parietal cortex of 18-20-month-old rats.

Cerebral blood flow velocity is associated with endothelial function in men [PDF]

open access: yesJournal of Men's Health, 2021
Background and objective: Reduction in cerebral blood flow with aging leads to cognitive decline and brain atrophy. Cerebrovascular hemodynamics are associated with vascular function.

Comparison of cerebral blood flow in subjects with and without chronic obstructive pulmonary disease from the population-based Rotterdam Study

open access: yesBMJ Open, 2021
Objectives Patients with chronic obstructive pulmonary disease (COPD) are at increased risk of cerebrovascular disease, which might be associated with decreases in cerebral blood flow. Since studies examining cerebral blood flow in COPD remain scarce and

Modeling of intracranial vessels and Simulation of cerebral blood flow [PDF]

open access: yesE3S Web of Conferences, 2020
The stable regulation of cerebral blood flow plays an important role in the normal operation of brain function. The disturbance of cerebral blood flow automatic regulation will lead to brain injury and lead to cerebrovascular disease. Therefore, it is of

Cerebral blood flow remains reduced after tilt testing in myalgic encephalomyelitis/chronic fatigue syndrome patients

open access: yesClinical Neurophysiology Practice, 2021
Objective: Orthostatic symptoms in myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) may be caused by an abnormal reduction in cerebral blood flow.

Study of the relationship between regional cerebral saturation and pCO2 changes during mechanical ventilation to evaluate modifications in cerebral perfusion in a newborn piglet model [PDF]

open access: yesBrazilian Journal of Medical and Biological Research, 2022
Near-infrared spectroscopy (NIRS) could be a useful continuous, non-invasive technique for monitoring the effect of partial pressure of carbon dioxide (PaCO2) fluctuations in the cerebral circulation during ventilation.

The effect of absent blood flow on the zebrafish cerebral and trunk vasculature

open access: yesVascular Biology, 2021
The role of blood flow in vascular development is complex and context-dependent. In this study, we quantify the effect of the lack of blood flow on embryonic vascular development on two vascular beds, namely the cerebral and trunk vasculature in ...

Dehydration accelerates reductions in cerebral blood flow during prolonged exercise in the heat without compromising brain metabolism [PDF]

open access: yes, 2015
Dehydration hastens the decline in cerebral blood flow (CBF) during incremental exercise, while the cerebral metabolic rate for oxygen (CMRO2) is preserved.

Cerebral vasoreactivity in response to a headof-bed position change is altered in patients with moderate and severe obstructive sleep apnea [PDF]

open access: yes, 2018
Obstructive sleep apnea (OSA) can impair cerebral vasoreactivity and is associated with an increased risk of cerebrovascular disease. Unfortunately, an easy-to-use, non-invasive, portable monitor of cerebral vasoreactivity does not exist. Therefore, we
