Fluorescein angiography (FA) and OCTA showed loss of small capillaries
but nonperfusion areas were not observed, confirming a diagnosis of nonischemic CRVO.
Previous studies indicated that exercise training enhanced the number of capillaries
per square millimeter of muscle in humans and these increases are greatest in slow twitch (ST) (Type I) and fast oxidative-glycolytic (FOG) skeletal muscle (9).
Lesions are made up of abundant vascular spaces and lobulated aggregates of closely packed capillaries
lined by a flattened epithelium without anaplastic or mitotic features.
At higher power, PCH lesions are composed of an abnormal proliferation of small, thin-walled capillaries
causing expansion of the alveolar septae (Figure 1, A and B).
Usually, the regulation of the blood flow in small blood vessels is associated with the contractile elements outside the endothelium, like the external muscle walls of the arterioles or the external contractile glial cells (pericytes) on the venules and capillaries
The best predictors were abnormal nailfold capillaries
and the presence of antinuclear antibodies (Arch.
When cardiogenic pulmonary edema develops, the extravasation of fluid from the pulmonary vasculature into the lungs generally occurs because of a disturbance of the pressures associated with Starling's law of the capillaries
. The pressures involved in the Starling equation are (1) hydrostatic pressure in the pulmonary capillary, (2) colloid osmotic pressure in the pulmonary capillary, (3) hydrostatic pressure in the pulmonary interstitium, and (4) colloid osmotic pressure in the pulmonary interstitium.
Radiation-induced changes in capillaries
constitute a basic injury in the pathogenesis of chronic radiation damage to the heart, lung, liver, kidney and brain.
In most applications, MEKC is performed in open capillaries
under alkaline conditions to generate a strong electroosmotic flow.
Unlike the pools and pipes where hydrodynamics and thermodynamics behave their conventional rules, says Smirnov, inside capillaries
and capillary-porous structures, fluid flow and heat and mass transfer at vaporization are shaped primarily by restricted spaces for nucleation, development, and motion of vapor phase elements.
Vascularity was determined for mammary tissue with the following measurements taken: the cross-sectional capillary area density (CAD, total capillary area as a proportion of tissue area), capillary number density (CND, total number of capillaries
per unit of tissue area), and capillary surface density (CSD, total capillary circumference per unit of tissue area).
A nitrogen-driven multi-barrel measurement system is said to, for the first time, make it possible to simultaneously run multi-point controlled stress measurements (depending on the number of capillaries
), independent of the chosen die geometries, where the same controlled stress is applied.
In this paper we discuss mainly such electromigration methods that are performed in thin capillaries
The reconstructed segments of the villous tree show parallel vessels of mature intermediate villi giving rise to the capillaries
of terminal villi.
The 6.5- x 5.5- x 11-cm device consists of a control box and a small remote sensor head which contains a capillary cartridge containing one to eight capillaries
. This allows high throughput and increased productivity in a miniature' format.
