Concha bullosa is the pneumatization of the concha and is one of the most common variations of the sinonasal anatomy. The histopathological changes caused by the infections which arise from the impaired aeration of conchal cavity are frequently found. Fungus ball of the nasal cavity is an extremely rare, fungal infection with only three cases reported previously. In this paper, we present the f...

objective (s): the scarcity of articular cartilage defect to repair due to absence of blood vessels and tissue engineering is one of the promising approaches for cartilage regeneration. the objective of this study was to prepare an extracellular matrix derived decellularized bovine articular cartilage scaffold and investigate its interactions with seeded rat bone marrow mesenchymal stem cells (...

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: Sharks get cancer rarely. A major difference between these animals and other species is that sharks have a great amount of cartilaginous tissue. Immunomodulatory effects of the cartilage of some species (cow) have been proved. Because the immune system has a major role in the defense of the body against cancer, we studied the effects of shark cartilage on the mouse and human immune...

background: previous studies have shown that galectin-3, a member of lectin family, is expressed in developing cartilage in mouse embryo and also in growth plate of long bones.   objective: in the present work, the expression pattern of galectin-3 in normal and various grades of osteoarthritic (oa) human articular cartilage has been studied.   methods: using immunohistochemistry and standard we...

Background: This work aimed to show and compare the degradation time of some of cartilage extracellular matrix components using an in vitro model for cartilage degradation induced by interleukin-1 alpha. It is known that elucidation of molecular events under Interleukin-1 alpha induction of bovine nasal cartilage could obtain useful data to understand more about involving mechanisms for tissue ...

bone has a capability to repair itself when it is fractured. repair involves the generation of intermediatetissues, such as fibrous connective tissue, cartilage and woven bone, before final bone healing can occur. theprocess of cartilage-to-bone transition (cbt) is a key for the achievement of rigid bone healing duringfracture repair. we tested this potential for elastic cartilage using a long ...
