Calcification of the auricular cartilages is a very rare finding observed in metabolic disorders like Addison's disease, adrenal insufficiency or diabetes. Its aetiology and physiopathological mechanisms remain unclear. It may be caused by exposure to cold or trauma in the cartilage but in a significant number of cases, ossification occurs without the identification of the precipitating cause o...

The objective of this study was to immunohistochemically elucidate the major extracellular matrix constituents of rabbit tracheal cartilage. The impetus for this project is the need for crucial design and validation criteria for tissue engineering juxtaposed with the conspicuous lack of trachea extracellular matrix data in the literature. Tracheal tissue specimens were harvested from New Zealan...

Osteoarthritis (OA) is a common disease in aged people, which results in degeneration of the articular cartilage and the meniscus [1]. Identification of the tiny changes of these cartilages is important to the early detection of OA and the monitoring of the disease progression. Recently, quantitative MR measurements, such as mapping of T1ρ, T2, and diffusion coefficient, have been used to evalu...

Diseases in articular cartilages have affected millions of people globally. Although the biochemical and cellular composition of articular cartilages is relatively simple, there is a limitation in the self-repair ability of the cartilage. Therefore, developing strategies for cartilage repair is very important. Here, we report on a new liquid resin preparation process of water-based polyurethane...

The tissue-separating capacity of chondral structures has been debated for more than 30 years, and one aspect that has particularly been questioned is whether the secondary cartilage of the mandibular condyle is comparable to primary growth cartilage, e.g. the epiphyseal growth plate. The present report summarizes information gained by using a specific interosseal transplantation method. These ...

Ungual cartilage ossification in the forelimb is a common finding in horses. Subtle abnormalities associated with the ungual cartilages can be difficult to identify on radiographs. Magnetic resonance (MR) imaging findings of 22 horses (23 forelimbs) with a fracture of the distal phalanx and ossified ungual cartilage were characterized and graded. All horses had a forelimb fracture. Eleven invol...

Most repair of heart lesions and pectus deformity has been performed in adult patients using long incisions, sternal splits, excision of deformed cartilages, and sternal turnover operations that could result in poor cosmesis and chest growth in children because of sternal devascularization. We performed simultaneous pectus repair and atrial septal defect closure in 2 children using a short long...
