International Journal of Cardiology: Heart & Vasculature, 2014 Objectives: The main objective of this study was to assess the blood flow rate and velocity in coronary artery stenosis using intracoronary frequency domain optical coherence tomography (FD-OCT). A correlation between fractional flow reserve (FFR) and FD-

Physiological Reports, 2022 Current sit‐to‐stand methods measuring dynamic cerebral autoregulation (dCA) do not capture the precise onset of the time delay (TD) response. Reduced sit‐to‐stand reactions in older adults and individuals post‐stroke could inadvertently introduce ...

Revealing Intraosseous Blood Flow in the Human Tibia With Ultrasound
JBMR Plus, 2021 Intraosseous blood circulation is thought to have a critical role in bone growth and remodeling, fracture healing, and bone disorders. However, it is rarely considered in clinical practice because of the absence of a suitable noninvasive in vivo ...

Aerobic exercise training increases cerebral blood flow in postmenopausal women
Artery Research, 2012 Background: Age-related decrease in cerebral blood flow is a risk factor for cognitive decline. Aerobic exercise training improves vascular and cognitive functions.

Extracorporeal Membrane Oxygenation and Cerebral Blood Flow Velocity in Children
Pediatric Critical Care Medicine, 2013 Objective: To determine how extracorporeal membrane oxygenation affects cerebral blood flow velocity and to determine whether specific changes in cerebral blood flow velocity may be associated with neurologic injury.

Abnormal Cerebrovascular Reactivity in Patients with Parkinson’s Disease
Parkinson's Disease, 2015 Background. Orthostatic hypotension (OH) is an important nonmotor manifestation of Parkinson’s disease (PD). Changes in cerebrovascular reactivity may contribute to this manifestation and can be monitored using transcranial Doppler. Objective.
