The present study investigated the use of mentalizing language, i.e. the utterance of internal states, from a developmental perspective according to attachment organization and disorganization. ...

The nature of gluonium states is reviewed. QCD is tested in the J/JI region obtaining guidelines for its applicability to the gluonium question. These guidelines along with other current theoretical models are used with new experimental results to examine the nature of the 1(1440) and 8(1640) mesons.

The authors describe systematic sampling bias from socalled "convenience cohorts" in a review of studies addressing the prognostic significance of the PAX– FOXO1 fusion genes in rhabdomyosarcoma (1). They cite evidence that in at least two studies, samples for which fusion gene status was not determined had a different overall survival than those for which fusion status was determined. They pos...
