Vinculin- and caldesmon-immunoreactive forms and actin isoform patterns were studied in samples of normal and atherosclerotic human aorta. After removal of adventitia and endothelium, the remaining tissue was divided into three layers: media, muscular-elastic (adjacent to media) intima, and subendothelial (juxtaluminal) intima. In media of normal aorta, meta-vinculin accounted for 41.0 +/- 0.9%...

Radiative heat transfer is analyzed in participating media consisting of long cylindrical fibers with a diameter in the limit of geometrical optics. The absorption and scattering coefficients and the scattering phase function of the medium are determined based on the discrete-level medium geometry and optical properties of individual fibers. The fibers are assumed to be randomly oriented and po...

Artery walls have three layers. The inner layer is the intima; this contains the endothelium, a layer of cells directly next to the blood which play an important role in controlling vascular tone, regulating transport into the wall and inhibiting smooth muscle cell proliferation and migration (Corti and Badimon, 2002). The middle layer is the media which is the muscular part of the wall, contai...

of unusual changes in the media. He gives an account of three necropsies of consecutive cases of rheumatic fever in young patients. The intima was not altered, but the media was thickened by increase of vascular elements, oedema and perivascular infiltration, with abundance of leucocytes and plasma cells. He noted signs of fibrous repair, and mentioned the possibility of this change predisposin...

We report the MR imaging findings of a solitary fibrous tumor involving the parapharyngeal space. The tumor was a well-circumscribed solid mass with a lobulated contour. It had the same signal intensity as the muscle on T1-weighted MR images, heterogeneously high signal intensity on T2-weighted images, and homogeneous strong enhancement after the administration of contrast material. It mimicked...
