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.

3. A long strand of proteins that are aggregated together in a beta-sheet structure; an amyloid fibril.

As listed in Table 1, the size of fibrils in the cross-section exhibited multi-order characters and increased with the increase of grafting yield, which is mainly related to the polyacrylic acid molecules as side chains grafted onto PSA molecular backbone.
The key to minimizing swelling in the wood cell wall is to minimize the swelling between elementary fibrils. Based on this insight, we decided to use SANS to investigate whether the known moisture-durable PF adhesive modifies the microfibrils, which are bundles of elementary fibrils.

Ultrasonication, microwave heating, water bath, and acid-base soaking [10-13] were performed to study the effects on the ultrastructure of collagen fibrils of beef tendons.
[S.sub.t] and [l.sub.t] are the average cross-sectional area and average length of all the LLDPE fibrils and n is the number of LLDPE fibrils during recovery.
It is one of the most promising, efficient, and energy-saving pretreatments to convert plant cellulose fibrils [21, 22].
These data indicate that FDE can effectively inhibit A[beta]1-42 fibril formation and significantly lower the neurotoxicity on the cultured SH-SY5Y cells, suggesting potential effect of the FDE on A[beta] clearance.

Small molecule inhibitors such as curcumin and quercetin that overlap in absorbance at the excitation wavelength of ThT can yield a false positive for fibril inhibition, as the fluorescence of ThT is decreased by an inner-filter effect [37].
In some instances, large segments were peeled from the fibres revealing the inner fibril structure (Figure 8h), and also skin layer was flaked off showing the resin layer underneath (Figure 8g).
