Continuing Education:
Introduction to statistical concepts:
Pugh and Torres-Saavedra provide an educational focus on basic statistical concepts—such as hypothesis testing, confidence intervals, parametric versus nonparametric tests, multiplicity, and diagnostic testing—that form the building blocks of research. Page 757

Focus on Molecular Imaging:
PARP-1 and beyond:
Puentes and colleagues review recent innovations in molecular imaging of DNA damage and repair, with an emphasis on poly[adenosine diphosphate ribose]polymerase-1 as an imaging target and predictive biomarker of response to therapy. Page 765
