Investigating the Relationship between Cerebral Blood Flow and Cognitive Function in Hemodialysis Patients.

Journal of the American Society of Nephrology, 2018
BACKGROUND The immediate and longer-term effects of hemodialysis on cerebral circulation, cerebral structure, and cognitive function are poorly understood. METHODS In a prospective observational cohort study of 97 adults (median age 59 years) receiving

Microglia modulate blood flow, neurovascular coupling, and hypoperfusion via purinergic actions

Journal of Experimental Medicine, 2022
Microglia modulate cerebral blood flow (CBF) through complex purinergic actions, which are mediated by dynamic, P2Y12 receptor-driven interactions with the vasculature. Microglial actions are partially independent of nitric oxide.

The future of ischemic stroke: flow from prehospital neuroprotection to definitive reperfusion. [PDF]

, 2014
Recent advances in ischemic stroke enable a seamless transition of the patient flow from the prehospital setting to definitive reperfusion, without the arbitrary separation of therapeutic phases of ischemia based on time alone.

Cerebral blood flow, blood supply, and cognition in Type 2 Diabetes Mellitus

Scientific Reports, 2016
We investigated whether type 2 diabetes (T2DM) and the presence of cognitive impairment are associated with altered cerebral blood flow (CBF). Forty-one participants with and thirty-nine without T2DM underwent 3-Tesla MRI, including a quantitative ...

Cerebral Blood Flow Autoregulation in Offspring From Experimentally Preeclamptic Rats and the Effect of Age

Frontiers in Physiology, 2022
Preeclampsia is a hypertensive disorder of pregnancy that causes significant, long term cardiovascular effects for both the mother and offspring. A previous study demonstrated that middle cerebral arteries in offspring from an experimental rat model of ...

Awake chronic mouse model of targeted pial vessel occlusion via photothrombosis [PDF]

, 2020
Animal models of stroke are used extensively to study the mechanisms involved in the acute and chronic phases of recovery following stroke. A translatable animal model that closely mimics the mechanisms of a human stroke is essential in understanding ...

In situ post-ischemic conditioning by temporary balloon occlusion for acute ischemic stroke: a modified reperfusion technique and adverse event monitoring

Frontiers in Neurology
BackgroundWith the development of endovascular therapy, the success rate of reperfusion for emergent large vessel occlusion (LVO) has significantly improved, but more achievements are still needed.

Cerebral blood flow autoregulation is impaired in schizophrenia [PDF]

, 2017
Patients with schizophrenia have a higher risk of cardiovascular diseases and higher mortality from them than does the general population; however, the underlying mechanism remains unclear.

Microstructured Thin Film Nitinol for a Neurovascular Flow-Diverter [PDF]

, 2016
A cerebral aneurysm occurs as a result of a weakened blood vessel, which allows blood to flow into a sac or a ballooned section. Recent advancement shows that a new device, ‘flow-diverter’, can divert blood flow away from the aneurysm sac.

Hyperventilation and Cerebral Blood Flow [PDF]

Stroke, 1972
Hypocapnic-hyperventilation has a profound, but probably temporary, effect on CBF, producing approximately a 2% decline in CBF for each 1 torr decline in P co co2 . This effect appears to be mediated through changes in perivascular pH of the cerebral resistance vessels ...
