After pharmacomechanical catheter-directed thrombolysis, there was residual focal flow-limiting thrombus within the filter.
Compared with traditional two-dimensional images, the focal color flow of honeycomb change occurs early and fades later.
Stroke is the result of occlusion or rupture of a brain artery, leading to loss of focal blood flow and brain function.
For instance, available data indicate that between earthquake magnitude and surface faulting parameters different scaling laws exist, and they are a function of the local geodynamic setting (including style of faulting, typical focal depths, heat flow).
Models of both permanent and transient (i.e. with restoration of blood flow) focal ischemia exist.
Expression of alpha muscle actin (αSMA) and the intermediate filament desmin, two proteins found in smooth muscle cells, as well as their adherence to the endovascular cells make them potential candidates for the regulation of capillary diameter and focal capillary blood flow [ 3, 8, 89, 91, 96- 99].
The consequences include the breakdown of the blood brain barrier, cerebral edema, reduced cerebral blood flow, focal areas of hypoperfusion, vascular thrombosis, ischemia, enhanced glucose metabolism via the anaerobic glycolytic pathway, and enhanced lactate accumulation in the brain and CSF [ 1].
This corresponds to mild, restricted diffusion on the echo-planar diffusion-weighted sequence (b), due to the slow speed of blood flow and focal enhancement on DCE imaging (c).
Yet few studies have evaluated if they are successful at enhancing actual functional connectivity (i.e. realized dispersal or gene flow) of focal species, or if this enhanced connectivity is enough to maintain genetic diversity and fitness of plant populations.
