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...

PURPOSE The purpose of this study was to determine accurately the part of the tragus to be used to form the Ala-Tragal line or Camper's line in orthognathic profile patients. MATERIALS AND METHODS 150 dentate subjects with age of 18-40 years with orthognathic profile were sampled. Life-size lateral digital photographs of the face with fox plane were taken in natural head position. Different a...

Aim: To compare the result of graft materials i.e. temporalis fascia, tragal perichondrium and ear lobule fat in various aspects but the prime interest would be the closure of tympanic membrane perforation and postoperative hearing improvement. Materials and methods: The study was carried out on 60 patients admitted for myringoplasty as per selection criteria in the Department of Ear Nose and T...

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...

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...

Recently, it has been proven that cartilage healing is difficult. The most commonly used treatments are autogenously cartilage grafting and allogeneic bone grafting, but grafts cannot fully meet treatment goals because of source, price, safety, and other concerns. Thus, a combination of biological materials and tissue engineering technology has become a recent trend in studies. Among the studie...

The importance of mesenchymal stem cells (MSCs), as adult stem cells (ASCs) able to divide into a variety of different cells is of utmost importance for stem cell researches. In this study, the ability of cartilage extract to induce differentiation of rat derived omentum tissue MSCs (rOT-MSCs) into chondrocyte cells (CCs) was investigated. After isolation of rOT-MSCs, they were co-cultured with...

Given the difficulties in accessing articular cartilage as a source of chondrocytes to be used in fabricating cartilage constructs, alternative sources are required. The present study examined chondrocytes from costal cartilage for their suitability in cartilage tissue engineering. Chondrocytes isolated from rat knee and rib hyaline cartilage were separately mixed with alginate and placed in a ...
