507 Couldwell, William T.Irving S. Cooper (1922-1985): a pioneer in functional neurosurgeryIrving S. Cooper (1922-1985), the son of a salesman, worked his way through high school, college, and medical school to become one of the pioneers in functional neurosurgery. He developed several novel techniques for the surgical management of Parkinson's disease and other crippling movement disord...Functional neurosurgery; Cryosurgery; Dystonia; Movement disorder; Parkinson's disease; Thalamotomy; Tremor; Neurosurgical history1998
508 Gesteland, Raymond F.; Atkins, John F.Origin and destiny of adenovirus proteinsLytic infection of human cells by adenovirus proceeds by a temporal expression of genes. Classically two phases have been defined: an early phase, which includes events occurring before the onset of DNA synthesis (8 hours), and a late phase, including events whose existence depends on the onset of...Protein Biosynthesis; DNA, Viral; Adenoviridae; RNA, Viral; Time Factors1975
509 Frederick, Jeanne M.The prenyl-binding protein PrBP/δ: A chaperone participating in intracellular traffickingExpressed ubiquitously, PrBP/d functions as chaperone/co-factor in the transport of a subset of prenylated proteins. PrBP/d features an immunoglobulin-like b-sandwich fold for lipid binding, and interacts with diverse partners. PrBP/d binds both C-terminal C15 and C20 prenyl side chains of phototran...2012-01-01
510 Simpson, Jamesina J.Substrate integrated waveguides optimized for ultrahigh-speed digital interconnectsThis paper reports an experimental and computational study of substrate integrated waveguides (SIWs) optimized for use as ultrahigh-speed bandpass waveguiding digital interconnects. The novelty of this study resides in our successful design, fabrication, and testing of low-loss SIWs that achieve 100...2006-01-01
511 Varner, Michael W.Trial of labor or repeat cesarean delivery in women with morbid obesity and previous cesarean delivery.OBJECTIVE: Assess effects of body mass index (BMI) on trial of labor after previous cesarean delivery and determine whether morbidly obese women have greater maternal and perinatal morbidity with trial of labor compared with elective repeat cesarean delivery. METHODS: Secondary analysis from a prosp...Pregnancy Outcome; Obesity; Repeat Cesarean Section; Body Mass Index2006-07

515 Battin, Margaret P.Continuous sedation until death: moral justifications of physicians and nurses─a content analysis of opinion piecesContinuous Sedation until Death (CSD), the act of reducing or removing the consciousness of an incurably ill patient until death, often provokes medical-ethical discussions in the opinion sections of medical and nursing journals. A content analysis of opinion pieces in medical and nursing literature...2012-01-01
516 Harpending, Henry C.; Rogers, Alan R.Detecting positive selection from genome scans of linkage disequilibriumThough a variety of linkage disequilibrium tests have recently been introduced to measure the signal of recent positive selection, the statistical properties of the various methods have not been directly compared. While most applications of these tests have suggested that positive selection has pl...Genome scans; Linkage disequilibrium; Gene trees2010
517 Olivera, Baldomero M.; Gray, William Robert; McIntosh, J. MichaelDifferential targeting of nicotinic acetylcholine receptors by novel αA-conotoxinsWe describe the isolation and characterization of two peptide toxins from Conus ermineus venom targeted to nicotinic acetylcholine receptors (nAChRs).
