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

Jorgensen, Erik | Genetic screens for synaptic function mutants in the nematode C. elegans | The 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; Cell | 1996 |

Nebeker, Jonathan R.; Samore, Matthew H | Hypersensitivity cases associated with drug-eluting coronary stents: a review of available cases from the research on adverse drug events and reports (RADAR) project | OBJECTIVES: 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 Vessels | 2006 |

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; Pathogen | 2004 |

Capecchi, Mario R. | Paralogous mouse Hox genes, Hoxa9, Hoxb9, and Hoxd9, function together to control development of the mammary gland in response to pregnancy. | Although the role of Hox genes in patterning the mammalian body plan has been studied extensively during embryonic and fetal development, relatively little is known concerning Hox gene function in adult animals. Analysis of mice with mutant Hoxa9, Hoxb9, and Hoxd9 genes shows that these paralogous g... | Embryonic and Fetal Development; Gene Expression Regulation, Developmental; Genotype; Mice, Knockout | 1999-01 |
