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.

Cerebral blood flow decrease as an early pathological mechanism in Alzheimer's disease
Acta Neuropathologica, 2020 Therapies targeting late events in Alzheimer’s disease (AD), including aggregation of amyloid beta (Aβ) and hyperphosphorylated tau, have largely failed, probably because they are given after significant neuronal damage has occurred.

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 ...

An Analysis of Resting-State Functional Transcranial Doppler Recordings from Middle Cerebral Arteries [PDF]
, 2013 Functional transcrannial Doppler (fTCD) is used for monitoring the hemodynamics characteristics of major cerebral arteries. Its resting-state characteristics are known only when considering the maximal velocity corresponding to the highest Doppler shift (

The Effects of Involuntary Respiratory Contractions on Cerebral Blood Flow during Maximal Apnoea in Trained Divers. [PDF]
PLoS ONE, 2013 The effects of involuntary respiratory contractions on the cerebral blood flow response to maximal apnoea is presently unclear. We hypothesised that while respiratory contractions may augment left ventricular stroke volume, cardiac output and ultimately ...

Fractal Rigidity in Migraine [PDF]
, 2003 We study the middle cerebral artery blood flow velocity (MCAfv) in humans using transcranial Doppler ultrasonography (TCD). Scaling properties of time series of the axial flow velocity averaged over a cardiac beat interval may be characterized by two ...

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

Systemic and cerebral blood flow [PDF]
Archives of Disease in Childhood - Fetal and Neonatal Edition, 2003 We read with interest the findings of Evans et al concerning the changes in middle cerebral artery (MCA) haemodynamics over the first two days after birth in preterm infants.1 Evans et al demonstrated a significant change in several Doppler velocity measures in the MCA, including systolic, diastolic, and mean velocity, pulsatility index and velocity ...
