Adult human articular cartilage has been maintained in organ culture for 8 days, and the culture medium, which was changed on alternate days, was pooled. Normal and rheumatoid cartilage was obtained from patients and 4 types of culture were prepared: (1) cartilage alone; (2) cartilage + D-penicillamine; (3) cartilage + homologous synovium; (4) cartilage, synovium, and D-penicillamine. The hexos...

Introduction. Microtia presents a congenital ear deformity ranging from minor and barely visible defect to complete absence of the ear. Currently, there are three options for reconstruction: autologous costal cartilage, silicon prothesis prosthetic Ear reconstruction with cartilage is usually performed in two stages. During first stage cartilaginous framework fabricated placed under skin, anato...

The objectives of this study were to determine pH, anti-Listeria and general antimicrobial properties of nisin on ready-to-eat vacuum-packaged diced turkey ham inoculated with Listeria monocytogenes, and the usage level that would exert maximum antimicrobial effect during 63 d of storage. Ready-to-eat diced turkey ham was inoculated with a 5-strain L. monocytogenes cocktail; treated with 0.2, 0...

OBJECTIVE The purpose of this study was to perform a quantitative evaluation of the effect of static magnetic field orientation on cartilage transverse (T2) relaxation time in the intact living joint and to determine the magnitude of the magic angle effect on in vivo femoral cartilage. MATERIALS AND METHODS Quantitative T2 maps of the femoral-tibial joint were obtained in eight asymptomatic m...

The friction and wear properties of silica/poly(tetrahydrofuran)/poly(?-caprolactone) (SiO2/PTHF/PCL-diCOOH) hybrid materials that are proposed as cartilage tissue engineering were investigated against living articular cartilage. A testing rig was designed to allow fresh bovine force compared for five compositions the biomaterial articulating freshly harvested in diluted calf serum. Under a non...

OBJECTIVE To examine the interaction between synovial fibroblasts and macrophages in the context of cartilage degradation. METHODS An in vitro model of human cartilage degradation was used, in which purified populations of fibroblasts and macrophages were added to a radiolabeled cartilage disc. Cartilage destruction was measured by the percentage of radiolabel release. RESULTS Fibroblasts, ...

The successful non-invasive imaging of articular cartilage in the equine patient is likely one of the most sought after goals in equine veterinary medicine. Articular cartilage may be one of the most difficult tissues to accurately image in its entirety in the in vivo horse. Magnetic Resonance Imaging has proven extremely useful for the successful imaging of articular cartilage in humans. For t...

objective(s) studies have shown that morphine, in addition to its analgesic properties, has several effects on cell proliferation and apoptosis. there is also evidence that opioid receptors are present on chondrocytes. our main objective in the present study was to investigate the effects of morphine on rat femur growth cartilage. materials and methods this research was carried out on 18 4-week...
