The radiograph is rapidly superseding the clinical examination as the diagnostic tool for acute ankle injuries. Twenty-four independent variables which might help distinguish between soft tissue injuries and fractures at the ankle were identified and then used prospectively to study 150 consecutive patients with ankle injuries. Nineteen patients had fractured ankles (12.7 per cent) and 131 (87....

The purpose of this study was to study the risk for injury and injury pattern in Swedish male elite football and to compare two different injury definitions. A prospective cohort study was conducted during 2001 on all 14 teams (310 players) in the Swedish top division. Injuries and individual exposure were recorded. Injury was defined as time-lost injury (715 injuries) and for comparison as tis...

Tissue engineering is based on three main factors including scaffolds, cells and growth factors. Natural scaffolds derived from decellularized tissues and organs have been successfully used in tissue engineering. Decellularization studies have shown that natural scaffolds which maintaine their main structure and properties could be a suitable tool for studying cellular behaviors and preparation...

Embryos and juveniles in many organisms repair tissue injuries better than adults. In this issue, Shyh-Chang et al. find that postnatal activation of Lin28a, a gene typically active in embryonic development, promotes better than normal tissue repair in mice, including following ear and digit injuries.
