Eosinophilic cellulitis/Wells' syndrome is a rare dermatosis with erythematous, urticarial plaques that become more indurated and eventually have grey blue discoloration. The histopathology is distinctive, with a diffuse infiltrate composed predominantly of eosinophils but admixed with lymphocytes, histicytes and occasionally multinucleated histiocytes. There is dermal edema with so called "fla...

Myocardial infarction was experimentally induced in rat hearts and harvested immediately, 7, 14 and 28 days after the infarction induction. Anterior wall infarct samples underwent biaxial tensile and uniaxial compressive testing. Orientation of collagen fibres was analysed following mechanical testing. In this paper, we present the tensile and compressive stress-strain raw data, the calculated ...

The ultrastructure of dermal fibres of a 200Myr thunniform ichthyosaur, Ichthyosaurus, specifically the 67nm axial repeat D-banding of the fibrils, which characterizes collagen, is presented for the first time by means of scanning electron microscopy (SEM) analysis. The fragment of material investigated is part of previously described fossilized skin comprising an architecture of layers of oppo...

Background. Cranial sutures are deformable joints between the bones of the skull, bridged by collagen fibres. They function to hold the bones of the skull together while allowing for mechanical stress transmission and deformation. Objective. The aim of this study is to investigate how cranial suture morphology, suture material property, and the arrangement of sutural collagen fibres influence t...

BACKGROUND AND AIMS Based on conflicting reports regarding the role of the fibrotic stromal response in cancer development--namely, that a desmoplastic reaction can favour either the host or the tumour--it is clear that the role of the stromal response is varied. We have classified the fibrotic stroma of rectal adenocarcinoma penetrating the muscularis propria, based on histologically identifie...

Actinobacillus pleuropneumoniae serotype 1 adhered to immobilized swine-lung collagen. Bacteria bound to collagen type I, III, IV and V. At 5 min incubation, 30 % of bacteria adhered to collagen, reaching saturation in around 90 min. Treatment of bacteria with divalent-metal chelators diminished their attachment to collagen, and Ca(2+) but not Mg(2+) increased it, suggesting Ca(2+) dependence f...
