Studies in vitro suggest that the C-terminus of tropoelastin mediates elastin polymerization through an interaction with microfibril-associated proteins. In this study we have used cultured auricular chondrocytes as a model system to examine whether this interaction is critical for elastic fibre formation in vivo. Auricular chondrocytes, which deposit an abundant elastic fibre matrix, were cult...

Chronic obstructive pulmonary disease (COPD) is characterized by loss of elastic fibres from small airways and alveolar walls, with the decrease in elastin increasing with disease severity. It is unclear why there is a lack of repair of elastic fibres. We have examined fibroblasts cultured from lung tissue from subjects with or without COPD to determine if the secretory profile explains lack of...

Experiments were performed to elucidate a possible mechanism for the peripheral circulatory disturbance caused by vibration. Rats were exposed to local vibration (60 Hz, 5 G) on their hind legs for four hours a day for 30 days or 90 days. With exposure for 30 days the small arteries at the exposed site did not change. With exposure for 90 days, however, disruption of the internal elastic lamina...

Carbon fibre electrodes can enable a solid-state battery to carry mechanical load as normal construction materials. The multifunctionality is promising for most lightweight applications. Like all electrode materials, both volume and elastic moduli of the carbon change during cycling. Such changes jeopardize integrity battery. Due challenging corrosion problem lithiated component in air, effect ...

Abstract The histological distinction between acute and chronic liver injury is a challenging aspect of histopathology. It traditionally based on the interpretation morphological changes to extracellular matrix (ECM) at sites hepatocyte loss using histochemical stains. Our aim was investigate whether immunohistochemistry multiplexing for collagen type (I & III) elastic fibres modified Victo...

The aim of the study was to show the changes in the great saphenous vein (GSV) wall at consecutive stages in the development of chronic vein disease (CVD) in patients qualified for a surgical procedure after physical examination and Doppler ultrasonography. Four groups of patients were formed (C2, C3, C4 and C5/6) according to clinical stage of the CEAP classification (C - clinical signs, E - a...

The elastic strain energy potential for nonlinear fibre-reinforced materials is customarily obtained by superposition of the potentials of the matrix and of each family of fibres. Composites with statistically oriented fibres, such as biological tissues, can be seen as being reinforced by a continuous infinity of fibre families, the orientation of which can be represented by means of a probabil...
