    Summary: This practical question and answer book covers topics within the field of neurocritical care, including aspects of neurology, neurosurgery, general critical care, and emergency medicine. Each chapter serves as a standalone test, comprised of approximately 100 questions, and closely mimics the tone and scope of the United Council for Neurologic Subspecialties (UCNS) certification exam in neurocritical care. Rationale and discussion are provided in the answers section at the end of each exam. This practical study guide will help prepare critical care fellows and residents from a variety of backgrounds (including internal medicine, neurology, anesthesiology, and emergency medicine) for the UCNS exam.

    (i) Phenotypic suppression by aminoglycoside antibiotics of a polyauxotrophic Shigella flexneri var. Y strain on partially completed minimal medium has shown that its Thr dependence is associated with nonsense mutation. Induced Thr+ revertants selected from the culture yielded clones correcting the lytic cycle of nonsense T4 mutant phages. Transfer of R1am plasmid to these clones carrying a nonsense mutation of ampicillin resistance was performed. In this manner a S. flexneri var. Y derivative was isolated which, on the basis of the phenotypic correction of T4 phages and R1am factor, proved to be a suppressor positive clone. (ii) From phage PE5 responsible for conversion of type antigen V, mutants were isolated that had lost their converting capacity. Selected Sup+ and control Sup- strains were treated with the mutant phages and examined for the appearance of type antigen V. Three phage mutants were found to induce antigen conversion only in Sup+ strains. (iii) The data suggest that, at least with phage PE5, the information for type antigen conversion is carried by phage genome.
