Synthetic Fourier Domain Optical Coherence Tomography

Advanced Photonics Research
A novel approach for image formation in optical coherence tomography (OCT) and microscopy is presented. The depth resolution of OCT, including recently developed nanosensitive OCT (nsOCT), is limited by the spectral bandwidth of the light source used for

Coronary Flow Reserve Measured by Myocardial Perfusion Imaging in Patients Following Percutaneous Coronary Intervention

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Despite achieving complete revascularization, patients with coronary artery disease (CAD) may experience adverse outcomes, potentially attributable to coronary microvascular dysfunction (CMD). Coronary flow reserve (CFR), which integrates both epicardial and microvascular coronary function, and a reduced CFR following complete ...

Design of a bioreactor to study the role of red blood cells in the transport of nitric oxide in the microcirculation [PDF]

, 2007
Nitric oxide (NO) plays an important role in physiological functions like vasodilation, neurotransmission, and inhibition of platelet aggregation. The endothelium-derived NO diffuses into the vascular lumen where it interacts with flowing blood as well ...

Biomarkers of lung congestion and injury in acute heart failure

ESC Heart Failure, Volume 12, Issue 2, Page 781-789, April 2025.
Abstract Acute heart failure (AHF) classification and management are primarily based on lung congestion and/or hypoperfusion. The quantification of the vascular and tissue lung damage is not standard practice though biomarkers of lung injury may play a relevant role in this context.

Impaired microcirculation after subarachnoid hemorrhage in an in vivo animal model

Scientific Reports, 2018
The influence of aneurysmal subarachnoid hemorrhage (SAH) on brain microcirculation has not yet been systematically investigated. We established an animal model to examine (1) the brain surface microcirculation (2) the influences of cerebrospinal fluid ...
