Collateral Circulation in Ischemic Stroke: An Updated Review [PDF]
Journal of Stroke, 2023 The collateral circulation plays a crucial role in maintaining perfusion to brain tissue in ischemic stroke, which prolongs the time window for effective therapies to be provided and ultimately avoids irreversible damage that may lead to worse clinical ...

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 ...

Cerebral hyperperfusion syndrome after endovascular stent graft reconstruction for postirradiated carotid blowout syndrome: a case report [PDF]
Journal of Neurocritical Care, 2022 Background Cerebral hyperperfusion syndrome (CHS) is a failure of autoregulation after a revascularization procedure. It has rarely been reported in patients with no pre-existing cerebral hypoperfusion. Case Report We present a rare case of a patient who

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.

Role of Circulating Exosomes in Cerebrovascular Diseases: A Comprehensive Review
Current Neuropharmacology, 2023 Abstract: Exosomes are lipid bilayer vesicles that contain multiple macromolecules secreted by the parent cells and play a vital role in intercellular communication. In recent years, the function of exosomes in cerebrovascular diseases (CVDs) has been intensively studied. Herein, we briefly review the current understanding of exosomes in CVDs.

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 ...
