fibril

 [fi´bril]
a minute fiber or filament. adj., adj fi´brillar, fi´brillary.
collagen f's delicate fibrils of collagen in connective tissue, composed of molecules of tropocollagen in linear array. In Type I collagen, the most common type, the tropocollagen molecules are associated in periodic, staggered arrays that give the appearance of cross-banding, forming unit fibrils; these unit fibrils are aggregated in bundles to form larger fibrils, with longitudinal striations, which may themselves be aggregated into fibers.
muscle fibril myofibril.

fi·bril

(fī'bril),
A minute fiber or component of a fiber.
Synonym(s): fibrilla

Type I collagen fibril (A); it is composed of unit fibrils, here shown negatively stained (B). The unit fibrils themselves comprise tropocollagen molecules in regular staggered arrays (C, D).

In contrast to most clay-containing blends, in these MFCs, substantial increase in fibril dimensions occurs as a consequence of the clay effect on the competition between the fibril coalescence and extension.
The structures, called amyloid fibrils, are also implicated in neurodegenerative conditions such as Alzheimer's and Parkinson's, and in prion diseases like Creutzfeldt-Jacob and mad cow disease.
The collagen fibrils deposited predominantly in the mesangium reveal unusual features ultrastructurally (Figures 10, A and B).
Evidence for association of an elastomer with charged groups on the fibril surface is provided by gravimetric determination of fiber content of engineered elastomer.
In view of that the details of fibril were not clear, O'Leary and Geil [33] measured the structure of PTFE fibril by electron diffraction and suggested that it was a kind of low-molecular-weight crystal.
In the research published August 28, researchers found that Rifamycin SV stopped the formation of protein fibrils by binding to an unfolded protein molecule with a particular shape, enabling for the first time, an unfolded protein of a particular shape to be identified as a target for the design of new inhibitors of fibril assembly.
A[beta] fibril stimulation leads to increased neuronal expression of COX-2.
Structurally similar to carbon nanotubes, the strong and versatile microscopic tubes whose diameter is measured in nanometers (a nanometer is one billionth of a meter/39 inches), Fibril BNNT has a variety of properties attractive to the research and commercial industry.
One disadvantage of this tubing is its tendency to kink during bending because of its fibril node morphology.
