(iii) [C.sub.V] and [E.sub.V] (between collagen and elastic fiber
contents in the vertical direction).
were completely or partially decreased from the papillary dermis to the reticular dermis in all anetoderma lesions.
Skin thinning in intrinsic skin aging is reportedly associated with the degeneration of collagen and elastic fibers
. In addition, several studies have supported an intimate relationship between cellular senescence and skin atrophy.
(14) Hence, they proposed a set of diagnostic criteria for a diagnosis of PPFE, the criteria comprising the presence of multilobar subpleural and/or centrilobular fibrous interstitial pneumonia characterized by more than 80% proliferation of elastic fibers
in the nonatelectatic lung in association with absent to scant chronic inflammation and no or rare granulomas.
Degenerative processes of elastic fibers
in sun-protected and sun-exposed skin: immunoelectron microscopic observation of elastin, fibrillin-1, amyloid P component, lysozyme and alpha1-antitrypsin.
Histological analysis showed that the elastic fiber
area decreased and collagen area increased in LF from LSS group, compared to LDH group.
Sea-island and split-type conjugate fibers have been used for making ultrafine fibers, side-by-side conjugate fibers for elastic fibers
, and sheath/core fibers for low-melting adhesive fibers.
An ultrastructural study of ultraviolet-induced elastic fiber
damage in hairless mouse skin.
The disorder is histologically characterized by a progressive calcification and fragmentation of elastic fibers
. PXE is caused by mutations in ABCC6  (ATP-binding cassette subfamily C, member 6), a gene encoding for the multidrug resistance--associated protein 6 (MRP6), an ATP-binding cassette (ABC) transporter protein with an as-yet-unidentified function (2-7).
A Rapid Digestive Technique to Expose Networks of Vascular Elastic Fibers

Recent research suggests that abnormalities of microfibrillar fibers, a component of the body's elastic fiber
system, may be significantly related to the cause or origin of the syndrome (Godfrey et al., 1990).
