Background It is known that there are biochemical markers of cartilage and bone tissue destruction, which reflect the metabolic processes occurring in tissues. For example, rheumatoid arthritis (RA), routine such as CTX-I, a degradation marker (C-terminal telopeptide type I collagen) CTX-II, II collagen), can be used. Also, to assess state tissue, determination collagen fragments by Urine Carti...

the importance of mesenchymal stem cells (mscs), as adult stem cells (ascs) able to divide into a variety of different cells is of utmost importance for stem cell researches. in this study, the ability of cartilage extract to induce differentiation of rat derived omentum tissue mscs (rot-mscs) into chondrocyte cells (ccs) was investigated. after isolation of rot-mscs, they were co-cultured with...

Diced rib cartilage is an acceptable option in severe nasal deformities. We present our preliminary experience in KAMC in nasal septoplasties using the autologous diced costal cartilage. This is a retrospective study of the 22 cases who needed the autologous diced costal cartilage in our centre in 4 years. All our patients needed autologous diced rib cartilages. Twelve were wrapped with tempora...

BACKGROUND Tissue engineering is used for the treatment of many diseases, and the ideal cell source for cartilage tissue engineering is chondrocytes. The main limitation of chondrocyte is the low number of cells in cartilage tissue engineering. This study investigated a suitable cell source with high proliferation rate to obtain a large number of chondrocytes. METHODS Adult cartilage t...

background: integrins are a family of transmembrane proteins that allow communication between the extracellular matrix and the interior of cells. chondrocytes, cells of articular cartilage, express integrins and these molecules appear to have a variety of roles including mechanotransduction. integrins are known to associate with a number of accessory molecules such as cd147 that may act to regu...

Objective- To determine the effect of the transcutaneous electrical neural stimulation on healing of hip joint cartilage defect in rabbit.Design- Experimental in vivo study.Animals- 12 adult New Zealand rabbits were used.Procedures- Under effective the right femoral head was subluxated and the maximum accessible cartilage was denuded up to subchondral bone using dental bit in each rabbit. Then ...

Lipomas are common benign adipose tissue tumours in dogs. Variants of lipomas are characterized by an additional component (e.g. capillaries in angiolipomas or fibrous connective tissue in fibrolipomas). In human medicine, the presence of cartilage or bone within a lipoma is a rare event. Mechanical stress, tropic disturbances, contact with periosteum and other unknown factors may contribute to...

introduction: to demonstrate surgical techniques and to compare the anatomical and functional outcomes between temporalis fascia and cartilage palisade grafting in type-i underlay tympanoplasty in patients with large/subtotal perforation.materials and methods:temporalis fascia and cartilage palisade grafting were conducted in group a and group b, respectively, each containing 30 patients with l...
