Cerebrovascular reactivity to hypercapnia during sevoflurane or desflurane anesthesia in rats [PDF]

Korean Journal of Anesthesiology, 2019
Background Hypercapnia causes dilation of cerebral vessels and increases cerebral blood flow, resulting in increased intracranial pressure. Sevoflurane is reported to preserve cerebrovascular carbon dioxide reactivity.

Melatonin does not attenuate dynamic cardiovascular and cerebrovascular reflex responses to acute hypotension in healthy men [PDF]

Korean Journal of Anesthesiology, 2012
BackgroundMelatonin has been shown to attenuate the reflex sympathetic increases that arise in response to orthostatic challenges. We tested the hypothesis that the attenuated sympathetic increase induced by melatonin premedication may weaken the ...

Quantitative Analysis of Brain CT Perfusion in Healthy Beagle Dogs: A Pilot Study

Veterinary Sciences, 2023
Brain computed tomography (CT) perfusion is a technique that allows for the fast evaluation of cerebral hemodynamics. However, quantitative studies of brain CT perfusion in veterinary medicine are lacking. The purpose of this study was to investigate the

Wavelet Autoregulation Monitoring Identifies Blood Pressures Associated With Brain Injury in Neonatal Hypoxic-Ischemic Encephalopathy

Frontiers in Neurology, 2021
Dysfunctional cerebrovascular autoregulation may contribute to neurologic injury in neonatal hypoxic-ischemic encephalopathy (HIE). Identifying the optimal mean arterial blood pressure (MAPopt) that best supports autoregulation could help identify ...

Endothelial dysfunction indicators and hemorheological properties in acute ischemic stroke

Анналы клинической и экспериментальной неврологии, 2017
We evaluated endothelial dysfunction and hemorheological indicatorsin acute ischemic stroke. The hemorheological indicators(blood viscosity, plasma viscosity, hematocrit, erythrocyte aggregationand deformability, fibrinogen concentration) were ...

Circulating Endothelial Progenitor Cells in Cerebrovascular Disease [PDF]

Journal of Clinical Neurology, 2008
Stroke is associated with high disability and mortality burdens worldwide, but there are few effective and widely available therapies. There is therefore a need to develop treatments that promote the repair and regeneration of ischemic brain tissue. In this regard, a population of adult stem cells-called endothelial progenitor cells (EPCs)-has been ...
