    Summary: The incidence and prevalence of post-traumatic arthritis (PTA) is increasing globally due to longevity of life and increased activity and injuries. Compared to the non-traumatic etiology of arthritis, post-traumatic arthritis differs in presentation, severity and complexity of management. This book illustrates all pertinent facets of post-traumatic arthritis, from the basic science and diagnostic modalities to their management and outcomes. The opening section reviews the current scientific literature on PTA and presents the preferred imaging techniques and interpretation methods. A unique chapter on the economic impact of PTA is also included here. The subsequent two sections discuss both the upper and lower extremity, respectively, with each joint covered in a dedicated chapter of its own, describing the mechanisms of injury, assessment, management strategies and outcomes. Case material provides real-world context for the concepts and techniques presented, supported by generous radiology and intraoperative photos and figures. With Post-Traumatic Arthritis, orthopedic surgeons, as well as trauma surgeons, rheumatologists and associated clinical staff, will receive a comprehensive framework on which to base their clinical decisions and enhance their post-operative outcomes.

    The effect of radioprotection of indolylalkylamines (5-methoxytryptamine) and aminothiols (cysteamine) on E. coli cells is practically absent if the cells have genetic defects in the repair systems. This means that the explanation of radioprotection by scavenging of free radicals is invalid and that specific repair mechanisms may be involved. In order to explain the radioprotective mechanism it was suggested that the radioprotectors interact with the damaged sites in DNA so that they become partly screened from repairing endonucleases. Under these conditions the reduction of incision rate results in diminished enzymatic induction of lethal double-strand breaks in DNA, this being important only in wild type cells. To prove this hypothesis an experimental procedure was developed using bacterial cells carrying plasmids (ColE1). This procedure enabled to determine the in vivo rate of enzymatic incision of gamma-sites. It was found that the protectors did not change the total amount of gamma-damages in DNA but reduced the rate of enzymatic incision.
