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 ...

Microfibrils in the myotendon junctions
Cells Tissues Organs, 1978Myotendon junctions in the rectus abdominis muscles of bull frogs were examined by the fixation combination of tannic acid and glutaraldehyde using electron microscopy. The features observed on myotendon junctions were the following: (1) There were many deep invaginations of muscle cell membrane at the end of the muscle fibers.

Fibrillin microfibrils are widely distributed extracellular matrix assemblies that endow elastic and nonelastic connective tissues with long-range elasticity. They direct tropoelastin deposition during elastic fibrillogenesis and form an outer mantle for mature elastic fibers.

Structure of the α-keratin microfibril
Journal of Molecular Biology, 1976The fine detail in the X-ray diffraction pattern of α-keratin has been explored out to spacings of 4 A by a direct mapping of the cylindrically averagedintensity transform. The meridional maxima lie on a set of layer lines corresponding to an axially projected repeat of structure of 470 A, and the distribution of nonmeridional maxima is consistent with

Structure and packing of microfibrils in collagen
Journal of Molecular Biology, 1973Abstract X-ray diffraction, patterns suggest that the five-stranded microfibrils in the collagen of rat tail tendon are supercoiled and packed together on a square lattice with a statistical distribution of axial displacements between nearest neighbours.

Extracellular microfibrils in development and disease
Cellular and Molecular Life Sciences, 2007Fibrillins are the structural components of extracellular microfibrils that impart physical properties to tissues, alone or together with elastin as elastic fibers. Genetic studies in mice have revealed that fibrillin-rich microfibrils are also involved in regulating developmental programs and homeostatic processes through the modulation of TGF-beta ...

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.
