Journal ArticleDOI
Evidence for a second valve system in lymphatics: endothelial microvalves
Jürgen Trzewik,Sandeep K. Mallipattu,Gerhard M. Artmann,Frank A. Delano,Geert W. Schmid-Schönbein +4 more
TL;DR: The hypothesis that initial lymphatics have a second, separate valve system that permits fluid to enter from the interstitium into the initial lymph channels but prevents escape back out into the tissue is investigated.
Journal ArticleDOI
Hemoglobin Dynamics in Red Blood Cells: Correlation to Body Temperature
Andreas M. Stadler,Ilya Digel,Gerhard M. Artmann,Jan Peter Embs,Jan Peter Embs,Giuseppe Zaccai,Georg Büldt +6 more
TL;DR: In this article, a transition in hemoglobin behavior at close to body temperature has been discovered by micropipette aspiration experiments on single red blood cells (RBCs) and circular dichroism spectroscopy on hemoglobin solutions.
Journal ArticleDOI
Enhanced adherence of beta-thalassaemic erythrocytes to endothelial cells.
TL;DR: It is proposed that enhanced RBC/EC adherence may contribute to the microcirculatory disorders observed in thalassaemia, especially in TI patients who are particularly known to suffer from leg ulcers.
Journal ArticleDOI
Temperature transitions of protein properties in human red blood cells.
TL;DR: Human red blood cells undergo a sudden change from blocking to passing through 1.3 +/- 0.2-micrometer micropipettes and Spectrin shows a uniform distribution along the aspirated RBC tongue above Tg in contrast to the linear gradient below Tg, attributed to an elastomeric transition of hemoglobin from being gel-like to a fluid and to an high-performance membrane proteins such as spectrin.
Journal ArticleDOI
Cytoplasmic water and hydration layer dynamics in human red blood cells.
Andreas M. Stadler,Jan Peter Embs,Ilya Digel,Gerhard M. Artmann,Tobias Unruh,Georg Büldt,Giuseppe Zaccai +6 more
TL;DR: The dynamics of water in human red blood cells was measured with quasielastic incoherent neutron scattering in the temperature range between 290 and 320 K to cover time scales of bulk water dynamics to reduced mobility interfacial water motions.
