Cerebral Autoregulation in Subarachnoid Hemorrhage
Frontiers in Neurology, 2021 Subarachnoid hemorrhage (SAH) is a devastating stroke subtype with a high rate of mortality and morbidity. The poor clinical outcome can be attributed to the biphasic course of the disease: even if the patient survives the initial bleeding emergency ...

Neonatal cerebrovascular autoregulation [PDF]
Pediatric Research, 2018 Cerebrovascular pressure autoregulation is the physiologic mechanism that holds cerebral blood flow (CBF) relatively constant across changes in cerebral perfusion pressure (CPP). Cerebral vasoreactivity refers to the vasoconstriction and vasodilation that occur during fluctuations in arterial blood pressure (ABP) to maintain autoregulation.

Cerebral autoregulation monitoring in neonates and infants after cardiac surgery with cardiopulmonary bypass - comparison of single ventricle and biventricular physiology [PDF]
Frontiers in PediatricsIntroductionCardiopulmonary bypass surgery can lead to impaired cerebral autoregulation with the risk for ischemia, hemorrhage and delirium. In particular, infants with single ventricle physiology have altered hemodynamics with persistent veno-arterial ...

Cerebral Autoregulation, Brain Injury, and the Transitioning Premature Infant [PDF]
Frontiers in Pediatrics, 2017 Improvements in clinical management of the preterm infant have reduced the rates of the two most common forms of brain injury, such as severe intraventricular hemorrhage and white matter injury, both of which are contributory factors in the development ...

CARM1 regulates tubulin autoregulation through PI3KC2α R175 methylation [PDF]
Cell Communication and SignalingTubulin is crucial in several cellular processes, including intracellular organization, organelle transport, motility, and chromosome segregation. Intracellular tubulin concentration is tightly regulated by an autoregulation mechanism, in which excess ...

Renal autoregulation and blood pressure management in circulatory shock
Critical Care, 2018 The importance of personalized blood pressure management is well recognized. Because renal pressure–flow relationships may vary among patients, understanding how renal autoregulation may influence blood pressure control is essential.

Cerebral Autoregulation in Man [PDF]
Stroke, 1974 Autoregulation was tested by regional blood flow (rCBF) and cardiohemodynamic measurements before and after induced systemic arterial hypertension in 16 patients with varying neurological disorders. Hypertension was induced by increasing the arterial blood pressure by an intravenous infusion of Aramine.

Modeling of Cerebral Blood Flow Autoregulation Using Mathematical Control Theory
Mathematics, 2022 A mathematical model of cerebral blood flow in the form of a dynamical system is studied. The cerebral blood flow autoregulation modeling problem is treated as a nonlinear control problem and the potential and applicability of the nonlinear control ...
