Microtubules and Microfibrils in Human Platelets
Thrombosis and Haemostasis, 1966SummaryThe microtubules and microfibrils of human platelets are described. They are studied under conditions that give as little alterations as possible. Conclusions on their localisation in vivo are drawn and their possible role in maintaining the platelet shape is discussed.

Exploring the Nature of Cellulose Microfibrils
Biomacromolecules, 2015Ultrathin cellulose microfibril fractions were extracted from spruce wood powder using combined delignification, TEMPO-catalyzed oxidation, and sonication processes. Small-angle X-ray scattering of these microfibril fractions in a "dilute" aqueous suspension (concentration 0.077 wt %) revealed that their shape was in the form of nanostrip with 4 nm ...

Microfibrils are supramolecular structures ubiquitously found in the extracellular matrix of elastic and nonelastic tissues. The three members of the cysteine-rich fibrillin family constitute the core of microfibrils. Mutations in fibrillin-1 and -2 lead to a number of heritable connective tissue disorders termed fibrillinopathies.

Comparison of Rhapidosomes and Asbestos Microfibrils
Science, 1978Rhapidosomes (cylindrical nucleoprotein rods of bacterial origin) show great structural similarity to the microfibrils of chrysotile asbestos when negatively stained and observed with the electron microscope. If the negative stain is omitted, the asbestos retains its structural detail whereas the rhapidosomes appear to be unstructured bodies.

Possible Roles of Microfibrils in Elastogenesis
Connective Tissue Research, 1981On examination in the electron microscope elastic tissue is seen to consist of an amorphous component surrounded by microfibrillar components. The exact relationship between these components is unknown, although during development the microfibrils appear before the amorphous material.

Analytical Biochemistry, 1998
A method is described for the purification of collagen VI microfibrils and fibrillin-containing microfibrils, respectively. High M(r) microfibril-rich preparations isolated from nuchal ligament by bacterial collagenase digestion and size fractionation were purified by CsCl density gradient centrifugation.

The substructure of α-keratin microfibrils
Journal of Ultrastructure Research, 1970The effect of underfocusing on the fine detail observed in the cross section of α -keratin microfibrils is discussed. It is shown that the apparent subdivision of the microfibrils into protofibrillar elements is coincidental with an underfocused granular phase image of similar dimensions and cannot, therefore, be accepted as a genuine structural ...

Mechanical performance and cellulose microfibrils in wood with high S2 microfibril angles
Journal of Materials Science, 2010Corewood and compression wood, both with high S2 microfibril angles, are the worst parts of the tree most in need of improvement in wood quality. This study focuses on the characteristics of cellulosic reinforcement in wood with high S2 microfibril angles lying between 35° and 60°, as well as the probable influence of these characteristics on wood ...

We report the results of an immunogold electron microscopical analysis on microfibrils from the arterial subendothelium showing that thrombospondin (TSP) is present on 40 nm-diameter structures joining 8-10 nm-diameter microfibrils containing fibrillin. They differ from type VI collagen which forms 3-5 nm-diameter microfibrils.

Colchicine and microfibril orientation
Protoplasma, 1976Investigations on the mechanism of orientation of the cellulose microfibrils of the green algaOocystis solitaria have been carried out. This organism demonstrates easily observable and highly ordered microfibrils in its wall, which are arranged parallel to one another and regularly alternate at 90‡ from layer to layer of which there are approximately ...
