Development of an ex vivo model for the study of cerebrovascular function utilizing isolated mouse olfactory artery [PDF]
, 2015 OBJECTIVE: Cerebral vessels, such as intracerebral perforating arterioles isolated from rat brain, have been widely used as an ex vivo model to study the cerebrovascular function associated with cerebrovascular disorders and the therapeutic effects of ...

Cerebrovascular reactivity during hypothermia and rewarming [PDF]
British Journal of Anaesthesia, 2007 Experimental evidence from a murine model of traumatic brain injury (TBI) suggests that hypothermia followed by fast rewarming may damage cerebral microcirculation. The effects of hypothermia and subsequent rewarming on cerebral vasoreactivity in human TBI are unknown.This is a retrospective analysis of data acquired during a prospective, observational

Cerebrovascular Reactivity and Central Arterial Stiffness in Habitually Exercising Healthy Adults
Frontiers in Physiology, 2018 Reduced cerebrovascular reactivity to a vasoactive stimulus is associated with age-related diseases such as stroke and cognitive decline. Habitual exercise is protective against cognitive decline and is associated with reduced stiffness of the large ...

Cerebral vasoreactivity in response to a headof-bed position change is altered in patients with moderate and severe obstructive sleep apnea [PDF]
, 2018 Obstructive sleep apnea (OSA) can impair cerebral vasoreactivity and is associated with an increased risk of cerebrovascular disease. Unfortunately, an easy-to-use, non-invasive, portable monitor of cerebral vasoreactivity does not exist. Therefore, we

Intensive Care Medicine Experimental, 2023 Background The aim of this study is to evaluate the impact of commonly administered sedatives (Propofol, Alfentanil, Fentanyl, and Midazolam) and vasopressor (Dobutamine, Ephedrine, Noradrenaline and Vasopressin) agents on cerebrovascular reactivity in ...

Cerebral autoregulation, brain injury, and the transitioning premature infant [PDF]
, 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 ...

Breath holding index in episodic primary headaches [PDF]
Vojnosanitetski Pregled, 2018 Background/Aim. Examination of cerebrovascular reactivity in patients with primary headaches is focused mainly on migraine, while the smaller number of studies deals with tensiontype and cluster headache, or comparison of cerebral haemodynamic in ...
