1 Kestle, John R. W.Change in ventricular size and effect of ventricular catheter placement in pediatric patients with shunted hydrocephalusOBJECTIVE: The multicenter, randomized pediatric cerebrospinal fluid shunt valve design trial found no difference in the rate of shunt failure between a standard valve, a siphon-reducing valve (Delta; Medtronic PS Medical, Goleta, CA), and a flow-limiting valve (Orbis Sigma; Cordis, Miami, FL); ho...Shunt failure; Valve design; Ventricular size; Ventricular catheter placement1999
2 Baehr, WolfgangCharacterization of the chicken GCAP gene array and analyses of GCAP1, GCAP2, and GC1 gene expression in normal and rd chicken pinealPURPOSE: This study had three objectives: (1) to characterize the structures of the chicken GCAP1 and GCAP2 genes; (2) to determine if GCAP1, GCAP2, and GC1 genes are expressed in chicken pineal gland; (3) if GC1 is expressed in chicken pineal, to determine if the GC1 null mutation carried by the re...Molecular Sequence Data; Promoter Regions (Genetics); Retinal Degeneration1999
3 Jones, Bryan W.; Jones, Christopher R.; Czajkowski, LauraFamilial advanced sleep-phase syndrome: a short-period circadian rhythmvariant in humansBiological circadian clocks oscillate with an approximately 24-hour period, are ubiquitous, and presumably confer a selective advantage by anticipating the transitions between day and night. The circadian rhythms of sleep, melatonin secretion and body core temperature are thought to be generated by ...Activity Cycles; Matched-Pair Analysis; Polysomnography1999

5 Baehr, Wolfgang; Thulin, CraigImmunolocalization and divergent roles of phosducin and phosducin-like protein in the retinaPURPOSE: These investigations were undertaken to compare and contrast the roles of phosducin and phosducin-like protein in the retina. METHODS: Phosducin and phosducin-like protein were compared in an in vitro assay measuring their inhibition of transducin binding to light-activated rhodopsin. The t...Antibody Specificity; Protein Binding; Rod Outer Segments1999
6 Schmidt, Meic H.Medical applications of space light-emitting diode technology-space station and beyondSpace light-emitting diode (LED) technology has provided medicine with a new tool capable of delivering light deep into tissues of the body, at wavelengths which are biologically optimal for cancer treatment and wound healing. This LED technology has already flown on Space Shuttle missions, and show...Photodynamic therapy; Lutetium Texaphyrin; Lutex; Canine glioma1999
7 Dailey, Andrew T.Modulation of macrophage and microglial responses to axonal injury in the peripheral and central nervous systemsOBJECTIVE: After axonal injury, macrophages rapidly infiltrate and become activated in the mammalian peripheral nervous system (PNS) but not the central nervous system (CNS). We used the dorsal root pathway to study factors that modulate the response of macrophages to degenerating axons in both the ...Axonal injury; Macrophage response; Microglial response; Peripheral nervous system; Lewis rats1999
8 Baehr, Wolfgang; Rao, Narayanam V.Molecular characterization of a third member of the guanylyl cyclase-activating protein subfamilyThe mammalian retina contains at least two guanylyl cyclases (GC1 and GC2) and two guanylyl cyclase-activating proteins (GCAP1 and GCAP2). Here we present evidence of the presence of a new photoreceptor-specific GCAP, termed GCAP3, which is closely related to GCAP1. The sequence similarity of GCAP3 ...Amino Acid Sequence; Cloning, Molecular; Gene Expression Regulation1999
9 Normann, Richard A.; Maynard, Edwin M.Neural interface for a cortical vision prosthesisThe development of a cortically based vision prosthesis has been hampered by a lack of basic experiments on phosphene psychophysics. This basic research has been hampered by the lack of a means to safely stimulate large numbers of cortical neurons. Recently, a number of laboratories have developed a...Neuroprosthetics; Artificial Vision; Electrode Arrays; Multielectrode Recordings; Biocompatibility1999
10 Normann, Richard A.; Maynard, Edwin M.Neuronal interactions improve cortical population coding of movement directionInteractions among groups of neurons in primary motor cortex (MI) may convey information about motor behavior. We investigated the information carried by interactions in MI of macaque monkeys using a novel multielectrode array to record simultaneously from 12-16 neurons during an arm-reaching task. ...Motor Cortex; Monkey; Population Coding; Movement1999
11 Zhang, KangNew locus for autosomal dominant stargardt-like disease maps to chromosome 4Stargardt disease (STGD) is the most common hereditary macular dystrophy and is characterized by decreased central vision, atrophy of the macula and underlying retinal-pigment epithelium, and frequent presence of prominent flecks in the posterior pole of the retina. STGD is most commonly inherited a...Haplotypes; Genetic Markers1999
12 Couldwell, William T.Prolactinomas: focus on indications, outcomes and management of recurrencesAlthough prolactinomas are discovered at autopsy with equal frequency in women and men, they present clinically in women far more often than in men. In children, "in whom they are the most common type of adenoma, prolactinomas are seen more often in girls than in boys. In a series of nearly 400 PRL...Outcome; Pituitary adenoma; Prognosis; Prolactin; Transsphenoidal surgery1999
13 Crandall, Alan S.Torn posterior capsule: prevention, recognition and managementModern cataract surgery performed with phacoemulsification allows meticulous intraocular control and minimal incision size, but has the inherent risk of capsular rupture. Therefore, surgeons performing cataract surgery will inevitably face the complication of a torn posterior capsule. Torn posteri...Capsulorrhexis complications; Phacoemulsification; Posterior capsular tears; Shallow anterior chamber; Suprachoroidal hemorrhage; Vitrectomy1999
