431 Kestle, John R. W.Comparison between magnetic resonance imaging and computed tomography for stereotactic coordinate determinationThe spatial accuracy of magnetic resonance imaging (MRI) has not been established for stereotactic surgery.

436 Schmidt, Meic H.; Couldwell, William T.Far lateral transcondylar transtubercular approach to lesions of the ventral foramen magnum and craniovertebral junctionThe craniovertebral junction, which consists of the lower one third of the clivus, the foramen magnum, and the CI and C2 vertebrae, is a common site for neoplastic, vascular, congenital, and degenerative lesions of the cranial base. The far lateral transcondylar transtubercular approach (commonlyr...Far-lateral; Transcondylar; Transtubercular; Ventral foramen magnum; Craniovertebral junction2007
437 Jorgensen, ErikGenetic screens for synaptic function mutants in the nematode C. elegansThe synapse is the site of a remarkable conversion of electrical signals into chemical signals. This conversion takes place when a depolarizing impulse enters the axon terminal and opens voltage-sensitive calcium channels; calcium then flows into the cell and initiates the fusion of synaptic vesicle...Vesicle; Neurotransmission; Cell1996
438 Nebeker, Jonathan R.; Samore, Matthew HHypersensitivity cases associated with drug-eluting coronary stents: a review of available cases from the research on adverse drug events and reports (RADAR) projectOBJECTIVES: We undertook the review of all available cases of hypersensitivity reactions after placement of a drug-eluting stent (DES) and classified potential causes. BACKGROUND: Six months after the approval of the first DES, the Food and Drug Administration (FDA) reported 50 hypersensitivity reac...Drug Hypersensitivity; Coronary Vessels2006
439 Potts, Wayne K.Infection-dependent phenotypes in MHC-congenic mice are not due to MHC: can we trust congenic animals?Congenic strains of mice are assumed to differ only at a single gene or region of the genome. These mice have great importance in evaluating the function of genes. However, their utility depends on the maintenance of this true congenic nature. Although, accumulating evidence suggests that congenic ...Strains; Mutations; Pathogen2004
