3 A: Photomicrograph of part of the tracheal bronchus of the tucuxi calf, with spacing between the rings (arrow) (He); B: Photomicrograph of trachea with elastic fibers
of tucuxi calf (HE); C: Tracheal bronchus photomicrograph of tucuxi calf (HE); D: Photomicrograph of fibrous tunic of the tucuxi calf (MEV); E: Visceral pulmonary pleura photomicrograph of adult boto (MEV).
At the same time, decrease of elastic fibers
in both the outer surface of TA and the subsinusoidal area was significantly higher in Groups 1 and 2.
The Pro-regions of lysyl oxidase and lysyl oxidase-like 1 are required for deposition onto elastic fibers
The umbilical arteries and vein both had inner transverse and outer longitudinally arranged elastic fibers
in the tunica intima.
In order to analyze the elastic fibers
the Weigert elastic staining method (Luna 1968) was used.
Then we performed a skin biopsy, whose histological examination revealed a thick fibrous dermic band associated with an increase in fragmented elastic fibers
and deposits of calcified material, which was ejected over the skin through the infundibular ostium (Figs.
Inner subendothelium was composed of dense irregular connective tissue with collagen fibres, elastic fibers
, and few smooth muscle cells.
It has activity on epidermal stem cells and elastic fibers
The elastic fibers
do play a role, but it's also the enzymes that degrade the matrix that break down both collagen and elastin over time.
Hydroquinone also breaks down collagen and elastic fibers
in the skin, reducing the firmness and smooth appearance of the skin.
In the fully developed skin lesions, the elastic fibers
in the mid-dermis are clumped, degenerated, fragmented and swollen, and the abnormal fibers stain positively for calcium.
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.
Elastase is an enzyme associated with the deterioration of elastin, a protein that is a vital part of elastic fibers
in the skin.
The elastic fibers
apply pressure to the surface of the skin, which aids to the circulation of blood.
A critical organic petrochemical raw material, 1,4-butanediol is widely used in the production of Permian basin ROY TR (PBT), with the engineering PBT being a key ingredient to make automotive parts and elastic fibers
