Blood flow velocity comparison in the eye capillaries and postcapillary venules between normal pregnant and non-pregnant women
(2020)Background: There is no consensus on how much and at what diameters the blood flow velocity changes in the female microcirculation during normal pregnancy. Methods: A non-contact, digital slit-lamp biomicroscopy system was ... -
EANM procedural guidelines for PET/CT quantitative myocardial perfusion imaging
(2021)The use of cardiac PET, and in particular of quantitative myocardial perfusion PET, has been growing during the last years, because scanners are becoming widely available and because several studies have convincingly ... -
Endothelin-1 plasma levels in hemodialysis treatment - The influence of type 2 diabetes
(2005)In patients on chronic hemodialysis the prevalence of atherosclerosis is increased and is by far the leading cause of morbidity and mortality. Endothelin-1, an endothelium-derived peptide with vasoconstrictive and mitogenic ... -
Influence of hemodialysis on the mean blood flow velocity in the middle cerebral artery
(2005)Background: Several effects of hemodialysis, including hemoconcentration, alterations of hemostasis or hemorheology and endothelial activation, could potentially interfere with cerebral blood flow (CBF) regulation. These ... -
Microcirculation-mediated preconditioning and intracellular hypothermia
(2018)Microcirculation is a network of perfused capillaries that connects macrocirculation with the cells. Although research has provided insight into microcirculatory blood flow, our knowledge remains limited. In this article, ... -
Relationship of Effective Circulating Volume with Sublingual Red Blood Cell Velocity and Microvessel Pressure Difference: A Clinical Investigation and Computational Fluid Dynamics Modeling
(2022)The characteristics of physiologic hemodynamic coherence are not well-investigated. We examined the physiological relationship between circulating blood volume, sublingual microcirculatory perfusion, and tissue oxygenation ... -
Use of hyperspectral/multispectral imaging in gastroenterology. Shedding some–different–light into the dark
(2019)Hyperspectral/Multispectral imaging (HSI/MSI) technologies are able to sample from tens to hundreds of spectral channels within the electromagnetic spectrum, exceeding the capabilities of human vision. These spectral ...
