Performance on the internal medicine second-year residency in-training examination predicts the outcome of the ABIM certifying examination.
For 223 residents from eight teaching hospitals, the results of the second-year in-training examination and the first-sitting certifying examination of the American Board of Internal Medicine were highly correlated. The results of the in-training examination can serve residents as an important measure of their preparedness for certification and can be useful in identifying the need for more intensive self-study strategies during the subsequent one and a half years.

Monoribosomal attachment to messenger ribonucleic acid in sodium fluoride-treated rabbit reticulocytes.
Mild proteolysis with Pronase selectively dissociates ribosomes not attached to mRNA into subunits; ribosomes attached to mRNA remain intact. A portion of monoribosomes from reticulocytes incubated with NaF resisted proteolytic dissociation. Recovery of mRNA from monoribosomes of NaF-treated reticulocytes therefore may be explained by persistent attachment of some monoribosomes to mRNA.
