Uncoupling of Microvascular Blood Flow and Capillary Density in Vascular Cognitive Impairment

Frontiers in Neurology, 2019
Cerebral small vessel disease (cSVD) plays an important role in dementia and is a major cause for vascular cognitive impairment (VCI). Recent studies hypothesized that capillary dysfunction including reduction of capillary patency, rather than a flow ...

Measurements of Blood Flow Velocity in the Microcirculation [PDF]

Upsala Journal of Medical Sciences, 1975
A method for the measurement of red blood cell velocity in the microcirculation is described. The technique is based on the on-line cross-correlation of the delay between optical signatures derived from photodetectors aligned in direction oflow. A specialised photodiode holder which can be inserted directly in place of an ocular is described.

Implications Enzymatic Degradation of the Endothelial Glycocalyx on the Microvascular Hemodynamics and the Arteriolar Red Cell Free Layer of the Rat Cremaster Muscle

Frontiers in Physiology, 2018
The endothelial glycocalyx is a complex network of glycoproteins, proteoglycans, and glycosaminoglycans; it lines the vascular endothelial cells facing the lumen of blood vessels forming the endothelial glycocalyx layer (EGL).
