Calcinosis is a connective tissue disorder classified into the following four types: metastatic; idiopathic; iatrogenic and dystrophic. Dystrophic calcinosis can occur, for example, in dermatomyositis, mainly in juvenile dermatomyositis, and is characterized by an abnormal deposition of calcium salts in affected skin, subcutaneous tissues, and muscles or tendons, with normal serum levels of cal...

The implantation of homologous femoral head cartilage in subcutaneous tissues of random bred Wistar rats results in both subchondral and articular surfaces becoming overlaid by an adherent granulation tissue comprising predominantly fibroblast-like cells. The response of the tissue to cartilage encapsulated with cotton fibres was also similar but erosions, mainly subchondral, were more evident ...

Calcinosis cutis is a condition characterized by the deposition of calcium salts in the skin and subcutaneous tissues, and patients suffering from it encounter various connective tissue disorders, such as dermatomyositis (DM), scleroderma, and systemic lupus erythematosus. Although calcinosis cutis is frequently accompanied by juvenile dermatomyositis, rare cases have been reported in adult pat...

A fibre-optic probe mounted on the strain gauge of a compression tester was pushed into beef roasts. Reflectance decreased through the subcutaneous adipose tissue and was inversely correlated with resistance to penetration (r = 0.82 at 450 nm and r = -0.84 at 700 nm, P < 0.01). Resistance peaked in the connective tissue of spinales dorsi. Despite illuminating several cubic centimetres of meat, ...

The purpose of this paper was to study the reaction of rat subcutaneous connective tissue to the implantation of dentin tubes filled with white mineral trioxide aggregate (MTA), a material that will be marketed. The tubes were implanted into rat subcutaneous tissue and the animals were sacrificed after 7 and 30 days. The undecalcified pieces were prepared for histological analysis with polarize...

Spontaneous pneumomediastinum (SPM); also known as mediastinal emphysema, is a rare and usually benign self-resolving appearance of extraluminal air in the mediastinum without any underlying trigger. This is an uncommon disorder mostly seen in the young males and classic clinical presentation is with chest pain, dyspnea, cough and appearance of subcutaneous emphysema. Although several connectiv...

INTRODUCTION Biocompatibility and antimicrobial activity of endodontic materials are of utmost importance. Considering the extensive applications of mineral trioxide aggregate (MTA) in dentistry and antimicrobial properties of silver nanoparticles, this study aimed to evaluate the subcutaneous inflammatory reaction of rat connective tissues to white MTA with and without nanosilver (NS) particle...

stem cells are of great interest for regenerating disturbed tissues and organs. these cells are commonly isolated from the bone marrow, but there has been interest in other tissues in the recent years. in this study, we evaluated the possibility of isolation of stem cells from oral connective tissue and investigated their characteristics.in this experimental study, sampling from the bone marrow...

The administration of calcium channel blockers has been associated with gingival overgrowth. However, there are few studies in humans or animals that evaluated the effect of diltiazem on gingival tissues. The present study assessed the influence of diltiazem, at different dosages and treatment duration, on gingival tissues of rats, using clinical, histological and histometric analyses. Eighty y...
