876 Stevenson, Jeff; Procter, Melinda; Hillyard, David R.Real time PCR assays for the detection of viral pathogens - are they the gold standard?Over the past decade, PCR testing for infectious agents in the clinical laboratory has begun to replace other methods, such as culture. PCR is often now referred to as the 'gold standard' in this field. Further evolution of this technology has seen the introduction of real time PCR, replacing tradit...Polymorphism; Target DNA2003-11-11
877 Hymas, Weston C.; Hillyard, David R.Real time RT-PCR assay for norovirus detection with eclipse probes and a non-competitive internal control.Noroviruses are the major causative agents of nonbacterial gastroenteritis worldwide and are estimated to cause approximately 23 million cases in the United States annually.

879 Frederick, Jeanne M.; Baehr, WolfgangReceptor for advanced glycation end products and age-related macular degeneration.Advanced glycation end products (AGE) exacerbate disease progression through two general mechanisms: modifying molecules and forming nondegradable aggregates, thus impairing normal cellular/tissue functions, and altering cellular function directly through receptor-mediated activation. In the present...Optic Atrophies, Hereditary; Apoptosis; Pigment Epithelium of Eye2004

883 Couldwell, William T.Recurrent infrasellar clival craniopharyngiomaThe patient is a 44-year-old man who underwent resection of a posterior nasopharynx tumor 12 years earlier via left lateral rhinotomy approach. The final pathological analysis indicated the tumor was a craniopharyngioma, and the patient subsequently underwent focal radiation. The patient returned t...Ectopic Craniopharyngioma; Recurrence; Infrasellar; Clivus2007
884 Varner, Michael W.; Hatasaka, Harry H.Recurrent pregnancy loss.Recurrent pregnancy loss is a frustrating clinical dilemma for both patients and physicians because, in most cases, causes are nebulous and few treatments with proven benefit can be offered. Involved, expensive tests have frequently been proposed and their use has often filtered into clinical practi...Recurrent Pregnancy Loss; Uterus/abnormalities; Chromosome Disorders; Abortion, Habitual1994-06
885 Varner, Michael W.Reduction in amniocentesis risks using a real-time needle guide procedure.Rates of complications associated with a second trimester genetic amniocentesis were studied in 918 patients, and complete infant follow-up was obtained. In 903 singleton pregnancies and 15 twin gestations, the procedure was performed under continuous sector scanning guidance through an attached nee...Amniocentesis; Ultrasonography; Pregnancy2007-01-25
886 Kestle, John R. W.Reduction of hemorrhage risk after stereotactic radiosurgery for cavernous malformationsThe benefits of radiosurgery for cavernous malformations are difficult to assess because of the unclear natural history of this vascular lesion, the inability to image malformation vessels, and the lack of an imaging technique that defines "cure." The authors selected for radiosurgery 47 patients w...Cavernous malformation; Gamma knife; Stereotactic radiosurgery1995
887 Kestle, John R. W.Reduction of transfusion rates in the surgical correction of sagittal synostosisObject. As public concern about the risks of blood transfusions increased in the mid-1990s, avoidance of transfusions became a goal of surgery for sagittal synostosis. This study was performed to confirm a hypothesized reduction in transfusion rates in recent years and to identify factors associated...Sagittal synostosis; Sagittal craniosynostosis; Craniectomy; Allogenic blood transfusion; Reduction2002
888 Capecchi, Mario R.Reexamination of gene targeting frequency as a function of the extent of homology between the targeting vector and the target locus.Mutations were targeted to the Hprt locus of mouse embryo-derived stem cells by using 22 different sequence replacement and sequence insertion vectors. The targeting frequency was examined at two sites within the Hprt locus as a function of the extent of homology between the targeting vector and the...Cell Line; DNA Transposable Elements; Embryo; Exons; Mice1992-08-12
889 Bernstein, Paul S.Reflection-based imaging of macular pigment distributions in infants and childrenWe have developed a reflection-based capability of the RetCam® platform, an FDA-cleared pediatric retinal-imaging instrument, for the purpose of measuring macular pigment levels as well as their spatial distributions in infants and children. Our modifications include narrow-band blue-wavelength exc...2013-01-01
890 Sanchez Alvarado, AlejandroRegeneration and the need for simpler model organismsThe problem of regeneration is fundamentally a problem of tissue homeostasis involving the replacement of cells lost to normal 18 wear and tear 19 (cell turnover), and/or injury. This attribute is of particular significance to organisms possessing relatively long lifespans, as maintenance of all bod...Molecular Pathways2004-05-29
891 Capecchi, Mario R.Regionally restricted developmental defects resulting from targeted disruption of the mouse homeobox gene hox-1.5.Gene targeting in mouse embryo-derived stem cells has been used to disrupt the homeobox gene hox-1.5. Mice heterozygous at the hox-1.5 locus appear normal, whereas hox-1.5-/hox-1.5- mice die at or shortly after birth. These homozygotes are athymic, aparathyroid, have reduced thyroid and submaxillary...Abnormalities, Multiple; Animals, Newborn; Arteries; Bone and Bones; Cartilage; Esophagus; Gene Expression; Heart Defects, Congenital; Organ Specificity; Parathyroid Glands; Pharynx; Thymus Gland; Thyroid Gland; Trachea1991-04-11

894 Kestle, John R. W.Relationship of intraoperative electrophysiological criteria to outcome after selective functional posterior rhizotomyAt British Columbia's Children's Hospital, the criteria used in selective functional posterior rhizotomy (SFPR) evolved in three distinct phases. In Phase 1 the electrophysiological criteria for abnormality included a low threshold to a single stimulation, a sustained response to 50-Hz stimulation, ...Selective posterior rhizotomy; Electrophysiological criteria; Intraoperative electrical stimulation1995
895 Capecchi, Mario R.Removing the vertebrate-specific TBP N terminus disrupts placental beta2m-dependent interactions with the maternal immune systemMammalian TBP consists of a 180 amino acid core that is common to all eukaryotes, fused to a vertebrate-specific N-terminal domain. We generated mice having a modified tbp allele, tbp(DeltaN), that produces a version of TBP lacking 111 of the 135 vertebrate-specific amino acids. Most tbp(DeltaN/Delt...Alleles; Animals, Genetically Modified; Binding Sites; Embryonic and Fetal Development; Evolution, Molecular; Female; Fetus; Immune Tolerance; Male; Mice; Mutation; ATA-Box Binding Protein2002-07-12
