When atherosclerosis is present, a clot can form inside of one of these small arteries, blocking blood flow in the artery.
The gouge (pieces of broken rock) produced during such slip may further complicate the picture by blocking the flow in the fracture and thereby reducing the fracture permeability (Lorenz 1999; Smart et al. 2001).
It has been suggested that EPS directly causes wilting by physically blocking water flow in the densely-colonized xylem vessels of infected hosts [14].
As the loading proceeded, this region was closing first, until it completely blocked the flow in the x-direction (Fig. 5b).
And by tracing red blood cells, we could map the blood flow speeds in a network of capillaries before and after we blocked blood flow in one capillary.
To test whether this affects the early heart, Hove's team used small beads to block blood flow in the zebrafish heart at 37 hours, when the heart is little more than a tube.
Only when phloretin is assumed to block paracellular flow in addition to transcellular flow is any inhibitory effect of phloretin on transepithelial glucose transport observed.
When pH values are lower than 5.5, uric acid tends to accumulate and form crystals that can block urine flow in the tubules [ 2, 4, 13].
In contrast, methoxamine (Hori et al, 1993), norepinephrine, dopamine, and metaraminol have less effect on vascular resistance in a3, a4, and a5 vessels, and do not block blood flow in tumour-feeding vessels (data not shown).
Combretastatin A-4 phosphate was found to block blood flow in capillaries supporting cancerous cells by completely disrupting the endothelial cell integrity leading to rapid tumor cell death [ 14, 15].
