Towards a physics informed digital twin to predict cerebral blood flow and cerebral vascular regulation. [PDF]

NPJ Digit Med
Cerebral blood flow is essential for brain function and is governed by cerebral perfusion pressure and physiological mechanisms collectively referred to as cerebral vascular regulation (CVR).

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

Frontiers 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]

Journal 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.

Fetal Cerebral Blood Flow (Dys)autoregulation. [PDF]

Diagnostics (Basel)
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 ...

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

E3S 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

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

BMJ 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

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

Clinical 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]

Brazilian 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

Vascular 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 ...

Cerebral blood flow monitoring

Journal of Neuroanaesthesiology and Critical Care, 2015
Brain is a unique organ of the body that receives highest amount of cardiac output and totally depend on the blood supply for its survival and no reserve of blood flow making it vulnerable for ischaemia. Other important properties of cerebral circulation
