The human temporomandibular joint (TMJ) develops from mesenchymal cells that form condensations appearing as condylar and temporal blastema which give rise to the respective anterior and posterior regions of the TMJ articular disc. Previous reports have shown the foetal disc to be avascular, with a high content of organized collagen fibres and a lesser content of elastic fibres. In this study, ...

The present study aimed to investigate kinetic alterations of collagen and elastic fibres and their association with cardiac function in the acute myocardial infarction (AMI) heart. AMI was generated in Sprague-Dawley rats by ligation of the left anterior descending coronary artery. Cardiac function was determined using B‑ultrasonography, AMI was verified using histopathology. The kinetics of c...

Although orcein has been in use for a long time as a stain for elastic fibres, it is only recently that it has been rediscovered for the demonstration of a variety of other substances. These include hepatitis B surface antigen (HBsAg),' 2 copper-associated protein,34 and more recently, intestinal sulphated mucins.35 Sipponen5 studied the normal distribution of orceinpositive mucin in the gastro...

The aim of the present study was to determine effect of two decellularized agents, sodium dodecyl sulphate (SDS) and Triton X-100, to the skeletal muscle tissue. Final scaffold was evaluated by several histological techniques to analyse preservation of essential structures including collagen and elastic fibres, basement membranes, glycosaminoglycans and also to confirm elimination of nuclear an...

Mucinous naevus (MN) is a type of benign hamartomatous cutaneous mucinoses characterized by deposition of excessive amounts of mucin in the superficial dermis in a diffuse pattern with absence of collagen and elastic fibres in the mucinous areas. It may be associated with features of connective tissue naevus of proteoglycan type [1]. There is paucity of literature regarding this interesting ent...

The constellation of pseudoxanthoma elasticum, ocular involvement and vascular disturbances is termed Gronblad Strandberg syndrome. Pseudoxanthoma elasticum is a genetic disorder characterized by progressive calcification and fragmentation of elastic fibres in the skin, retina and the cardiovascular system. Typically the cutaneous lesions begin in childhood, but because of their asymptomatic na...

The cocoon of the commercial silkworm Bombyx mori is used as a model natural nonwoven composite to formulate a model for structural properties of nonwoven composites. The model is based upon open cell foam structures for the intrinsic undamaged elastic properties using the component materials in the cocoon, combined with the effect of gradual loss of connectivity in the interfiber bonding as th...

An investigation of skin lymphatics in leprosy has been undertaken. Examination of 62 skin biopsies from 31 patients with various classifications of leprosy has revealed dilated initial lymphatics within granulomas of lepromatous leprosy, but no significant abnormalities in non-lepromatous disease or in non-granulomatous skin. Colloidal carbon injected intra-lesionally failed to appear within g...

The almost forgotten method of intermingled skin grafting of allogeneic material with small autogeneic islets, once developed in the People's Republic of China, proves the feasibility of permanent healing of even extensive burn wounds, at low cost, and therefore an effective treatment possibility in poorer countries, as well as under conditions of a burn disaster. Intermingled skin grafting obt...

Abstract A mathematical model for nematic liquid crystal elastomers is proposed that mimics the elastic response of cat skin where reorientation dermal fibres produces an increase in thickness direction under tensile stretch. To capture this unusual effect, uniaxial order parameter elastomer allowed to decrease then again, and critical stretch at which change monotonicity occurs director also r...
