1 Olson, Randall J.; Coldwell, Karin D.; Compton, Bruce J.; Giddings, John C.Sedimentation field-flow fractionation: a method for studying particulates in cataractous lensIt is shown that the technique of sedimentation field-flow fractionation (sedimentation [sed] FFF) can be used to determine the particle content and particle size distribution of normal and cataractous lenses. A 31-year-old normal human lens, for example, showed a particle content of 1.5% by weight ...Fractionation; Cataractous Lens; Particulates1984
2 Baehr, WolfgangHuman interstitial retinoid-binding protein. Gene structure and primary structureInterstitial retinoid-binding protein (IRBP) is synthesized and secreted by rod photoreceptor cells into the interphotoreceptor matrix and is known to bind retinoids and fatty acids. We have used cDNA clones encoding human IRBP to isolate a 15-kilobase genomic fragment that encompasses the complete ...Molecular Sequence Data; Eye Proteins; Retinol-Binding Proteins; Messenger RNA1989-05-15
3 Baehr, WolfgangTissue-specific expression in transgenic mice directed by the 5'-flanking sequences of the human gene encoding interphotoreceptor retinoid-binding proteinInterphotoreceptor retinoid-binding protein (IRBP) is an extracellular protein that has been suggested to participate in the visual process as a carrier for visual retinoids. A chimeric gene composed of the human IRBP promoter fused to the bacterial reporter gene chloramphenicol acetyltransferase (C...Restriction Mapping; Nucleic Acid Hybridization; Mice; Gene Expression1990-05-25
4 Baehr, Wolfgang; Frederick, Jeanne M.; Church-Kopish, Jill; Howes, KimberlyMutant rhodopsin transgene expression on a null backgroundPURPOSE. To study mechanisms leading to photoreceptor degeneration in mouse models for autosomal dominant retinitis pigmentosa (adRP) based on the rhodopsin P23H mutation. METHODS. Mice of a transgenic line expressing a rhodopsin triple mutant, V20G, P23H, and P27L (GHL), were mated with rhodopsin (...Mutant Rhodopsin; Photoreceptor Degeneration; Autosomal Dominant Retinitis Pigmentosa; Rhodopsin2001-03
5 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
6 Bernstein, Paul S.; Gellermann, WernerMacular pigment Raman detector for clinical applicationsClinical studies of carotenoid macular pigments (MP) have been limited by the lack of noninvasive, objective instruments. We introduce a novel noninvasive optical instrument, an MP Raman detector, for assessment of the carotenoid status of the human retina in vivo. The instrument uses resonant excit...Diagnosis, Computer-Assisted; Equipment Failure Analysis; Sensitivity and Specificity2004
7 Baehr, Wolfgang; Prestwich, Glenn D.Photoreceptor cGMP phosphodiesterase delta subunit (PDEdelta) functions as a prenyl-binding proteinBovine PDEdelta was originally copurified with rod cGMP phosphodiesterase (PDE) and shown to interact with prenylated, carboxymethylated C-terminal Cys residues. Other studies showed that PDEdelta can interact with several small GTPases including Rab13, Ras, Rap, and Rho6, all of which are prenylate...Fluorescence Resonance Energy Transfer; GTP Phosphohydrolases; Immunohistochemistry2004
8 Bernstein, Paul S.; Gellermann, WernerNonmydriatic fluorescence-based quantitative imaging of human macular pigment distributions.We have developed a CCD-camera-based nonmydriatic instrument that detects fluorescence from retinal lipofuscin chromophores ("autofluorescence") as a means to indirectly quantify and spatially image the distribution of macular pigment (MP). The lipofuscin fluorescence intensity is reduced at all ret...Cytology; Sensitivity and Specificity2006-10
