Cerebral autoregulation is compromised during simulated fluctuations in gravitational stress [PDF]

, 2018
Gravity places considerable stress on the cardiovascular system but cerebral autoregulation usually protects the cerebral blood vessels from fluctuations in blood pressure.

Effect of the maternal sleep disturbances and obstructive sleep apnea on feto‐placental Doppler: A systematic review

Journal of Sleep Research, Volume 34, Issue 4, August 2025.
Literature evidenced an association of maternal obstructive sleep apnea (OSA) with significant obstetric complications. Moreover, the OSA and its effect on feto‐placental circulation had not been extensively examined. Our objective is to explore the possible impact of OSA on the feto‐placental indices evaluated through the Doppler study.

Sudden bilateral loss of vision in a 19-year-old man [PDF]

, 2015
Introduction: Posterior Reversible Leukoencephalopathy Syndrome (PRES) is caused by ischaemia commonly affecting the posterior cerebral vasculature. It presents with sudden decreased vision, headaches, nausea, vomiting, seizures, and altered mental ...

Dynamic cerebral autoregulation estimates derived from near infrared spectroscopy and transcranial Doppler are similar after correction for transit time and blood flow and blood volume oscillations

Journal of Cerebral Blood Flow and Metabolism, 2018
We analysed mean arterial blood pressure, cerebral blood flow velocity, oxygenated haemoglobin and deoxygenated haemoglobin signals to estimate dynamic cerebral autoregulation.

Extended model of impaired cerebral autoregulation in preterm infants: Heuristic feedback control

Mathematical Biosciences and Engineering, 2019
Cerebral autoregulation is the ability to keep almost constant cerebral blood flow (CBF) for some range of changing the mean arterial pressure (MAP). In preterm infants, this range is usually very small, even absent, and a passive (linear) dependence of ...
