background:several investigations showed cartilaginouscells in fibrous tissue of the free part of the penis in one humpedcamel. objectives: the aim of this study was accurate assessmentof existence of cartilaginous cells in penis shaft of onehumpedcamel. methods: six camel penises from maturedcamels more than 3 years-old were collected from an abattoir.different specimens were prepared from eac...

conclusions we feel this rare, currently unclassified variant of a tibial tubercle avulsion fracture should be recognised and consideration taken to adding it to existing classification systems. introduction a sleeve fracture classically describes an avulsion of cartilage or periosteum with or without osseous fragments and usually occurs at the inferior margin of the patella. tibial tubercle sl...

SW, an 84-year-old African American female, presented to an outside institution complaining of dull, intermittent abdominal pain in the anterolateral and suprapubic regions. Decreased appetite, nausea, and general weakness accompanied this pain. Physical exam revealed a soft, non-tender mass in the left upper quadrant that extended 20 cm below the costal margin. A separate 2 cm mass, in the per...

In this study we examined enhancement effects of Artemisinin plus Glucantime and shark cartilage extract, on promastigotes and amastigotes of L.infantum in in vitro condition.The toxicity of artemisinin, glucantime and shark cartilage extract on the L. infantum promastigotes and amastigote-infected macrophages was evaluated using MTT assay. The role of these drugs in inducing apoptosis in proma...

Objective- To evaluate the biological compatibility of differentiated stem cells embedded in poly-vinyl-alcohol (PVA) scaffolds for repair of distal femoral cartilage defect.   Design- Experimental in vivo study. Animals- Twelve adult male New Zealand white rabbits were used which were divided into two groups (I, II) six rabbits each.   Procedures- Mesenchymal stem cells were isolated from h...

Bone marrow stromal cells can give rise to several mesenchymal lineages. The existence of a common stem/progenitor cell, the mesenchymal stem cell, has been proposed, but which developmental stages follow this mesenchymal multipotent progenitor is not known. Based on experimental evidence, a model of mesenchymal stem cell differentiation has been proposed in which individual lineages branch dir...

background cartilage tissue has limited regenerative capacity and the management of cartilage defects has always been a challenging issue. platelet-rich plasma (prp) has been recently been used to improve healing of cartilage defects. in the present experiment, we aimed to investigate the effects of prp on regeneration capacity as well as survival of the cartilage grafts in a rabbit model. meth...
