Two simple capillary loops (arrowheads) aside a capillary loop displaying double-twisted limbs (arrow) of the vomeronasal organ olfactory epithelium.
Denaturation occurs after podocyte injury and the separation of glomerular basement membrane (shedding) causes expansion of the capillary loop, exposure of the tubular basement membrane, and Bowman capsule adhesion.
One of the advantages of a capillary loop is that the meniscus in the evaporator wick will automatically adjust its radius of curvature such that the resulting capillary pressure is equal to the total system pressure drop.
The fetal vessels of the terminal villi are therefore represented by capillary loops, parts of which are sinusoidally dilated, arranged such that three to five terminal villi are supplied by an individual coiled capillary loop.
Further branching of a simple capillary loop results in forming a more complicated capillary bed, consisting of longitudinally oriented branches interconnected by short capillary segments (Fig.
[P.sub.GC], [P.sub.BS], and [[PI].sub.BS] remain essentially unchanged along the capillary loop. As a result, NFP decreases along the length of the capillary and in some species is zero before or at the end of the capillary.
B) Parametric data: number of visible capillary loops in every square millimetre (value obtained from the average of the two observations for each examined area); capillary loop calibre (values obtained from the average of the two observations for each examined area).
Numerous glomerular wireloop lesions and hyaline capillary loop thrombi were seen.
Immunofluorescence staining showed deposits of immunoglobulin M, immunoglobulin G, immunoglobulin A, as well as C3 and C1q in mesangium and capillary loops, with segmental and diffuse distribution.
Endothelial cells lining the capillary loops were immunohistochemically stained with CD34 (Figure 3), which has been reported as the one of the most useful markers of PG (3).
