Migraine and patent foramen ovale: correlation, coexistence, dependence. A narrative review

open access: yesHeadache: The Journal of Head and Face Pain, EarlyView.
Plain Language Summary This review looked at what scientists know about the connection between migraine and a small heart opening called a patent foramen ovale (PFO). It showed that people with migraine, especially with aura, often have PFO, but it is not certain whether closing this heart opening helps prevent strokes in these patients.

In Vivo Dynamic Coronary Arteries Blood Flow Imaging Based on Multi‐Cycle Phase Clustering Ultrafast Ultrasound

open access: yesAdvanced Science
Echocardiography is the most primary clinical modality for dynamic cardiac imaging. However, the vigorous motion of myocardial tissue inherently causes inevitable signal aliasing between blood flow and myocardial tissue in traditional Doppler ultrasound ...

Analytical Validation of a Novel Point‐Of‐Care Quantitative Immunoassay for Feline N‐Terminal Pro‐Brain Natriuretic Peptide

open access: yesVeterinary Clinical Pathology, EarlyView.
ABSTRACT Background Point‐of‐care testing (POC) is widely utilized for rapid results for many different analytes. A new feline‐specific N‐terminal pro‐brain natriuretic peptide (NT‐proBNP) quantitative assay (Vcheck V200, Bionote Inc) is currently available but has not undergone independent validation.

Blood flow restriction: The acute effects of body tilting and reduced gravity analogues on limb occlusion pressure

open access: yesExperimental Physiology, EarlyView.
Abstract Blood flow restriction (BFR) has been identified as a potential countermeasure to mitigate physiological deconditioning during spaceflight. Guidelines recommend that tourniquet pressure be prescribed relative to limb occlusion pressure (LOP); however, it is unclear whether body tilting or reduced gravity analogues influence LOP.
