Objective: This study was designed to evaluate the clinical symptoms and sonographic characteristics of femoral trochlear cartilage in patients with knee joint osteoarthritis (OA). Methods: This cross-sectional study was conducted on 94 patients with painful primary knee OA according to the American College of Rheumatology criteria with a visual analog scale pain score of 30 mm or more. Clinica...

Background: Surgical drainage and antibiotic therapy are the cornerstones of treatment protocols in septic arthritis; however, in some circumstances, the diagnosis and initiation of treatment may be retarded by slow disease progression or the time when the patient’s condition precludes early surgery. Therefore, it is beneficial to find ways to reduce the amount of articular injury. This study a...

introduction: the use of cartilage as a grafting material has been advocated in cases where there is a high risk of graft failure, such as subtotal perforations, adhesive processes, and residual defects after primary tympanoplasties. the purpose of this study was to compare the graft acceptance rates and auditory outcomes of cartilage tympanoplasty operations using a palisade technique with tho...

management of mesenchymal stem cells (mscs) capabilities to differentiate into osteogenic and chondrogenic lineages would be of utmost importance for their future use in difficult to treat cases of destroyed bone and cartilage. thus, an understanding of the epigenetic mechanisms as important modulators of stem cell differentiation might be useful. epigenetic mechanism refers to a process that r...

  Objective(s): Osteoarthritis is one of the most common diseases in middle-aged population in the world. Cartilage tissue engineering (TE) has been presented as an effort to introduce the best combination of cells, biomaterial scaffolds and stimulating growth factors to produce a cartilage tissue similar to the natural articular cartilage. In this study, the chondrogenic potential of adipose d...

Introduction: Laryngotracheal stenosis can be caused after traumatic injuries to the neck from the subglottic larynx to the trachea. Patients with laryngotracheal stenosis often need a tracheotomy and occasionally may become tracheotomy dependent. Different procedures have been described for the management of these lesions. Management options include techniques of endoscopic dilation, laser res...

Background: Shark cartilage is one of the complementary medicines for cancer patients that inhibits tumor progression by several mechanisms. There is not sufficient evidence on its effects on human immune system thereby we investigated its modulatory effects on some cellular immune response parameters in breast cancer patients. Material and methods: After preparation of shark cartilage powder ...

Shark cartilage is considered as a natural dietary supplement consisting of anti-angiogenic, immunostimulatory, and anti-inflammatory characteristics. Therefore, this study was designed to inspect the possibility that whitecheek shark (Carcharhinus dussumieri) cartilage proteins motivate expression of NKG2D, CXCR3, NKP46, and NKP44 receptors on natural killer cells and their activities against ...

Background & Aims: One of cell- based technical issues associated with cartilage repair assay is delivering cells to the site of the parts where damage is created. Mesenchymal stem cells (MSCs) with their chondrogenic potential are ideal candidates for cartilage regeneration. High expression of cartilage hypertrophy markers by MSCs would result in apoptosis and ossification. This investigation ...
