Obesity and the microvasculature [PDF]

open access: yes, 2013
Overweight and obesity are thought to significantly influence a person's risk of cardiovascular disease, possibly via its effect on the microvasculature.

Precision and Accuracy of Dimensional Assessment of Luminal Contours by Commercially Available Quantitative Angiography Software as a Prerequisite to Angiography Based FFR and Other Derived Parametrics

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Accurate dimensional measurements are critical for quantitative coronary angiography (QCA) and serve as the first step in angiography‐based fractional flow reserve (FFR) calculations. Aims To compare minimum lumen diameter (MLD) measurements across multiple QCA or anigo‐based FFR software programs using phantom models.

Impact of Menstrual Cycle and Oral Contraceptives on Haematological and Inflammatory Biomarkers in Highly Trained Female Athletes

open access: yesDrug Testing and Analysis, EarlyView.
In highly trained female athletes, haematological and inflammatory biomarkers were found to be independent of menstrual cycle phase, but oral contraceptive use increased transferrin, reticulocyte count and triglycerides and decreased interleukin‐6.

An Updated Review of Methods and Advancements in Microvascular Blood Flow Imaging [PDF]

open access: yesMicrocirculation. 2016 Jul;23(5):345-63, 2019
There has been a consistent growth in research involving imaging of microvasculature over the past few decades. By 2008, publications mentioning the microcirculation had grown more than 2000 per annum. Many techniques have been demonstrated for measurement of the microcirculation ranging from the earliest invasive techniques to the present high speed ...

Hybrid M-mode-like OCT imaging of 3D microvasculature in vivo using reference-free processing of complex-valued B-scans [PDF]

open access: yes, 2014
We propose a novel OCT-based method for visualizing microvasculature in 3D using reference-free processing of individual complex-valued B-scans with highly overlapped A-scans. In the lateral direction of such a B-scan, the amplitude and phase of speckles corresponding to vessel regions exhibit faster variability, and thus can be detected without ...

Nonlinear model order reduction for problems with microstructure using mesh informed neural networks [PDF]

open access: yesarXiv, 2023
Many applications in computational physics involve approximating problems with microstructure, characterized by multiple spatial scales in their data. However, these numerical solutions are often computationally expensive due to the need to capture fine details at small scales.

Biomarkers of lung congestion and injury in acute heart failure

open access: yesESC 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.

Influence of erythrocyte density on aggregability as a marker of cell age: Dissociation dynamics in extensional flow [PDF]

open access: yesJournal of Biomechanics, Volume 183, April 2025, 112603
Blood rheology and microcirculation are strongly influenced by red blood cell (RBC) aggregation. The aggregability of RBCs can vary significantly due to factors such as their mechanical and membrane surface properties, which are affected by cell aging in vivo.
