1 Baehr, WolfgangCalcium-sensitive particulate guanylyl cyclase as a modulator of cAMP in olfactory receptor neuronsThe second messengers cAMP and inositol-1,4,5-triphosphate have been implicated in olfaction in various species. The odorant-induced cGMP response was investigated using cilia preparations and olfactory primary cultures. Odorants cause a delayed and sustained elevation of cGMP. A component of this c...Calcium-Binding Proteins; Nerve Tissue Proteins; Rats, Sprague-Dawley1998
2 Baehr, Wolfgang; Zhang, Kang; Kolb, HelgaGene array and expression of mouse retina guanylate cyclase activating proteins 1 and 2PURPOSE: To identify gene arrangement, chromosomal localization, and expression pattern of mouse guanylate cyclase activating proteins GCAP1 and GCAP2, retina-specific Ca2+-binding proteins, and photoreceptor guanylate cyclase activators. METHODS: The GCAP1 and GCAP2 genes were cloned from genomic l...Molecular Sequence Data; Guanylate Cyclase-Activating Proteins; In Situ Hybridization, Fluorescence1998
3 Fu, YingbinMechanism of reductive activation of potato tuber ADP-glucose pyrophosphorylase.The potato tuber (Solanum tuberosum L.) ADP-glucose pyrophosphorylase activity is activated by a incubation with ADP-glucose and dithiothreitol or by ATP, glucose- 1-phosphate, Ca2+, and dithiothreitol. The activation was accompanied by the appearance of new sulfhydryl groups as determined with 5, 5...Glucosephosphates; Enzyme Activation; Adenosine Triphosphate1998
4 Bernstein, Paul S.; Gellermann, WernerRaman detection of macular carotenoid pigments in intact human retinaPURPOSE: To develop and test a novel noninvasive optical technique suitable for the objective measurement of macular carotenoid levels in human retina. METHODS: A resonance Raman scattering apparatus was constructed to measure carotenoid levels in flat-mounted human retinas and eyecups and in experi...Rana pipiens; Spectrum Analysis, Raman; Xanthophylls1998
5 Normann, Richard A.; Shah, Maulik R.Study of printed spiral coils for neuroprosthetic transcranial telemetry applicationsWe have explored the use of printed spiral coils (PSC's) for neuroprosthetic transcranial telemetry applications. We fabricated two-dimensional PSC's on a thin (25 microns) polyimide substrate using copper (35 microns) as a conducting material. All the coils had a fixed inner diameter of 1.0 cm. We ...Blindness; Neuroprosthesis; Transcranial Telemetry System; Prosthesis Design1998
6 Olson, Randall J.; Crandall, Alan S.; Caldwell, Karin D.; Jensen, Michael K.Intraoperative crystallization on the intraocular lens surfacePURPOSE: To report a physician survey, laboratory studies, and clinical observations of intraoperative crystallization on the surface of the intraocular lens (IOL). METHOD: We sent a survey to all ophthalmologists in the states of Wyoming, Idaho, Montana, Utah, and Colorado asking whether crystalliz...Cataract Extraction; Intraoperative Complications; Risk Factors1998-08
7 Swallow, Charles E.; Tsuruda, Jay S.; Digre, Kathleen B.; Glaser, Matthew J.; Davidson, H. Christian; Harnsberger, H. RicTerson syndrome: CT evaluation in 12 patients.PURPOSE: Terson syndrome may be overlooked in the acute setting and often requires ophthalmologic intervention to prevent long-term visual loss. In this syndrome, vitreous or retinal hemorrhage results from an abrupt rise in intracranial pressure, leading to retinal venous hypertension and intraocul...Retinal Hemorrhage; Visual Acuity; Vitreous Hemorrhage1998-04
8 Gouw, Launce G.; McKenna, Catherine K.; Digre, Kathleen B.; Placek, Louis J.Analysis of the dynamic mutation in the SCA7 gene shows marked parental effects on CAG repeat transmission.The gene for spinocerebellar ataxia 7 (SCA7) includes a transcribed, translated CAG tract that is expanded in SCA7 patients. We have determined expansions in 73 individuals from 17 SCA7 kindreds and compared them with repeat lengths of 180 unaffected individuals. Subjects with abnormal expansions co...Genetics; Biosynthesis; SCA7 Gene1998-03-07
