  • elasticity
  • When the blood contains inadequate amounts of A1AT or functionally defective A1AT (such as in alpha-1 antitrypsin deficiency), neutrophil elastase is excessively free to break down elastin, degrading the elasticity of the lungs, which results in respiratory complications, such as chronic obstructive pulmonary disease, in adults. (wikipedia.org)
  • actin
  • Real-time polymerase chain reaction results showed a significant increase in the expression of α-smooth muscle actin and calponin on ELAC fibers with insoluble elastin, suggesting that incorporation of insoluble elastin induces a contractile phenotype in SMCs after two weeks of culture on ELAC fibers. (fit.edu)
  • structures
  • Not to be confused with fibers or filaments, fibrils tend to have diameters ranging from 10-100 nanometers (whereas fibers are micro to milli-scale structures and filaments have diameters approximately 10-50 nanometers in size). (wikipedia.org)
  • arteries
  • Previous studies have attempted to address the limitations of TEVGs by developing scaffolds that mimic the composition (collagen and elastin) of native arteries to better match the mechanical properties of the graft with the native tissue. (fit.edu)
  • In conclusion, insoluble elastin incorporated ELAC fibers have the potential to be used for the development of functional TEVGs for the repair and replacement of small-diameter arteries. (fit.edu)
  • soluble
  • In the current study, based on the principles of isoelectric focusing, two different types of elastin (soluble and insoluble) were incorporated into highly oriented electrochemically aligned collagen (ELAC) fibers and the effect of elastin incorporation on the mechanical properties of the ELAC fibers and smooth muscle cell (SMC) phenotype was investigated.

  • lysine
  • These reactive aldehydes and allysines can react with lysine and other allysine residues to crosslink and form desmosine, isodesmosine, and a number of other polyfunctional crosslinks that join surrounding elastin molecules to build an elastin matrix and elastic fiber. (wikipedia.org)
  • consists
  • A specialized version of the hydrostatic skeleton is a called a muscular hydrostat, which consists of a tightly packed array of three-dimensional muscle fibers surrounding a hydrostatic body. (wikipedia.org)
  • skin
  • In the skin, the pigment alters the structure of the fibers causing enlargement and curling. (wikipedia.org)
  • The structure of soft bodied skin can be characterized by a patterned fiber arrangement, which provides the shape and structure for a soft bodied animals. (wikipedia.org)
  • found
  • Extrapolating from an in-vitro elastin model under physiological conditions, the researchers found that the ratios of IDP to DESP corresponded extremely closely with values based on both a calculation of a theoretical Chichibabin pyridine synthesis of 3 mol allysine and 1 mol ammonia, and reported ratios of 2,3,5- to 3,4,5-trisubstituted pyridine ratios of a Chichibabin pyridine synthesis involving phenylacetaldehyde. (wikipedia.org)
  • They concluded with relative certainty that the pyridine cross-links found in elastin were, in fact, due to an in-vivo Chichibabin pyridine synthesis of ammonia and allysine. (wikipedia.org)
  • main
  • There are two main types of muscle fibers orientations that are responsible for the movement: the circular orientations and longitudinal orientations. (wikipedia.org)
  • occur
  • The fiber angle (the angle the fiber makes with the long axis of the body) plays a critical role in torsion, if the angle is greater than 54°44', during muscle contraction, torsion and elongation will occur. (wikipedia.org)
  • If the fiber angle is less than 54°44', torsion and shortening will occur. (wikipedia.org)
  • include
  • Symptoms include: yellow-brown, banana-shaped fibers caviar-like papules brown-grey or blue-black hyper-pigmentation The majority of the lesions will be seen on areas of the body that get the most sun. (wikipedia.org)
  • results
  • The results indicate that elastin incorporation significantly decreased the modulus of ELAC fibers to converge upon that of native vessels. (fit.edu)
  • Immunofluorescence results showed that calponin expression increased with time on all fibers. (fit.edu)
  • body
  • The arrangement of the fibers around a hydrostatic body limits the range of movement of the hydrostatic body (the "body" of a soft bodied animal) and defines the way the hydrostatic body moves. (wikipedia.org)
  • soft
  • Soft bodied animals such as starfish rely on the arrangement of the fibers in their tube feet for movement. (wikipedia.org)
  • Further
  • Further, a significant increase in yield strain and decrease in Young's modulus was observed on all fibers post SMC culture compared with before the culture. (fit.edu)
  • cartilage
  • Organic Sulfide: Sulfur is an important mineral element that constitutes a human body structure, including skin, hair, nails, internal organs and articular cartilage.Doctors pointed out that MSM (methylthiomide methane, organic sulfide) can help cartilage matrix support, equivalent to elastin, and can strengthen the strength of ligament cells, increase the amount of mucus secretion.

  • tissues
  • Pseudoxanthoma elasticum (PXE), also known as Grönblad-Strandberg syndrome, is a genetic disease that causes fragmentation and mineralization of elastic fibers in some tissues. (wikipedia.org)
  • Comparison between fresh and digested tissues shows that, at 35% strain, a minimum of 48% of the arterial load is carried by elastin, and a minimum of 43% of the change in stiffness of arterial tissue is due to the change in elastin stiffness. (wikipedia.org)
  • Tissue
  • Verhoeff's stain forms a variety of cationic, anionic and non-ionic bonds with elastin, the main constituent of elastic fiber tissue. (wikipedia.org)
  • Elastin has a strong affinity for the iron-hematoxylin complex formed by the reagents in the stain and will hence retain dye longer than other tissue elements. (wikipedia.org)
  • This allows elastin to remain stained, while remaining tissue elements are decolorized. (wikipedia.org)
  • Elastin is also an important load-bearing tissue in the bodies of vertebrates and used in places where mechanical energy is required to be stored. (wikipedia.org)
  • arterial
  • These observations demonstrate that MFAP4, a new player in cardiovascular pathologies, is redundant for normal cardiovascular development and arterial elastin assembly, but plays an important role in regenerative responses of the arterial wall. (mouseclinic.de)

  • tendons
  • Normal healthy tendons are composed mostly of parallel arrays of collagen fibers closely packed together. (wikipedia.org)
  • The dry mass of normal tendons, which makes up about 30% of their total mass, is composed of about 86% collagen, 2% elastin, 1-5% proteoglycans, and 0.2% inorganic components such as copper, manganese, and calcium. (wikipedia.org)
  • lungs
  • When the blood contains inadequate amounts of A1AT or functionally defective A1AT (such as in alpha-1 antitrypsin deficiency), neutrophil elastase is excessively free to break down elastin, degrading the elasticity of the lungs, which results in respiratory complications, such as chronic obstructive pulmonary disease, in adults.
