Objective- Current trends emphasize the acceleration of fracture healing on the ground that in doing so, the limitation of mobility and complications associated with recovery period are reduced. The present study aims to compare autogenic costal cartilage with Chitosan scaffold in canine humeral defect healing. Design- Experimental study Animal-15 adult male dogs Procedures-...
Purpose: Dedifferentiation of the chondrocyte from rat articular cartilage with multiple subcultures and study of the redifferentiation potential of the cells into bone, cartilage and fat cell lineages. Materials and Methods: In this experimental study, chondrocytes from rat articular cartilage were isolated and expanded through several successive subcultures during which the expression levels ...
background in rhinoplasty, functional and cosmetic problems of the nose are corrected. these problems cause imbalance between the nasal subunit and face. throughout these deformities, there are 4 variants, so there is a need for careful preoperative evaluation either for treatment or prevention of the occurrence. according to functional and aesthetic effects of these variables in rhinoplasty, e...
enrofloxacin is a synthetic chemotherapeutic agent from the class of the fluoroquinolones that is widely used to treat bacterial infections. it is metabolized to ciprofloxacin in the body as active metabolite. fluoroquinolones change in the articular cartilage, especially with high doses and more than two weeks use. so, due to relatively excessive use of enrofloxacin in mammals and similarity o...
conclusions it can be concluded that due to some bioactive and nutrient factors, mscs secretions could be used for recovery of oa as well as prevention of articular cartilage matrix degeneration, using a high dose of cell secretions. results the results revealed a decrease of proteoglycan content in the superficial and intermediate zones and presence of surface fibrillation. therefore, oa induc...
background: hyaline cartilage defects exhibit a major challenge in the field of orthopedic surgery owing to its limited repair capacity. on the other hand, mesenchymal stem cells (mscs) are regarded as potent cells with a property of cartilage regeneration. we aimed to optimize marrow-derived msc chondrogenic culture using a small bioactive molecule referred to as bio. methods: mscs from the ma...
Introduction: There are some routine two-dimensional sequences, including short tau inversion recovery (STIR), T2-weighted fast-spin echo (T2W-FSE), and proton-density fast spin-echo for diagnosing osteoarthritis and lesions of the knee cartilage. However, these sequences have some disadvantages, such as long scan time, inadequate spatial resolution, and suboptimal tis...
Background and Objective: Articular cartilage abnormalities are important factors of skeletal disorders and usually are related to glycosaminoglycans synthesis in the cartilage tissue. Presence of some vitamins, amino acids, and minerals increases cartilage regeneration. In this study, Medicago sativa (Alfalfa), which is high in some vitamins, amino acids and minerals, was used for cartilage he...
objective: cartilage mass produced from mesenchymal stem cell (msc) differentiation would be a suitable candidate for use in regenerative medicine. since the proper function of cartilage tissue is largely dependent on matrix glycosaminoglycan (gag) contents, the objective of this study was to investigate the enhancing effect of two gsk3 inhibitors on the gag content of cartilage produced by hum...
Background and purpose: Osteoarthritis is a common degenerative joint disease affecting the synovial joints. Cartilage lesion is an important disorder at different degrees associated with osteoarthritis. The purpose of this systematic review was to determine whether magnetic resonance imaging (MRI) is a valid and reliable tool to detect the articular cartilage lesions in patients with knee oste...
