Gesteland, Raymond F. | Translation of Rl7 RNA fragments | Examination of the events during infection of cells by RNA phages reveals phemonomena that are surprisingly complex for a virus that has only enough information to code for three to four proteins. The coat protein is synthesized at a rapid rate through most of the infectious cycle making it the pre... | Electrophoresis; RNA, Messenger; Peptide Biosynthesis; Kinetics | 1969 |

Gesteland, Raymond F.; Atkins, John F.; Baranov, Pavel V. | P-site tRNA is a crucial initiator of ribosomal frameshifting | The expression of some genes requires a high proportion of ribosomes to shift at a specific site into one of the two alternative frames. This utilized frameshifting provides a unique tool for studying reading frame control. Peptidyl-tRNA slippage has been invoked to explain many cases of programmed ... | Translation; Recoding; Kinetic Model; Frameshifting; Ribosome | 2004 |

Normann, Richard A.; Abbasi, Masoud; Johansson,Torbjorn | Silicon carbide enhanced thermomigration | The widespread acceptance of thermomigration technology to produce through-chip interconnects has been impaired by (i) a random walk of the Si-Al liquid eutectic inclusion as it traverses the wafer, and (ii) a ?surface barrier? which allows thermomigration of only relatively large inclusions.

Normann, Richard A.; Chandler, John P. | Effects of calcium ions on L-type horizontal cells in the isolated turtle retina | A technique by which the retina can be isolated from the turtle eye is described. Scanning electron microscopy revealed morphological variability between preparations and also between regions of the same one.

Normann, Richard A. | Signal transmission from red cones to horizontal cells in the turtle retina | 1. Intracellular recordings were made from L-type horizontal cells in the retina of the turtle Pseudemys scripta elegans. The responses were evoked by 500 msec pulses of 'white' light. 2. L-type horizontal cells were classified as either, 'small receptive field' s.r.f. or 'large receptive field' l.r... | Turtles; Synapses; Retina; Photoreceptors | 1979 |

Baehr, Wolfgang; Prestwich, Glenn D. | Photoreceptor cGMP phosphodiesterase delta subunit (PDEdelta) functions as a prenyl-binding protein | Bovine 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; Immunohistochemistry | 2004 |

Varner, Michael W.; Clark, Edward B.; Fernando, Kumari L.; Mathews, V. John | Robust estimation of fetal heart rate variability using Doppler ultrasound. | This paper presents a new measure of heart rate variability (HRV) that can be estimated using Doppler ultrasound techniques and is robust to variations in the angle of incidence of the ultrasound beam and the measurement noise. This measure employs the multiple signal characterization (MUSIC) algori... | Prenatal Ultrasonography; Fetal Heart Rate; Blood Flow Velocity; Algorithms | 2003-08 |

Gesteland, Raymond F.; Krapcho, Karen J.; Talbot, Phil; Thulin, Craig | Crystallization of the MS2 translational repressor alone and complexed to bromouridine | The coat protein from the MS2 bacteriophage plays a dual role by encapsidating viral RNA and also by binding RNA as a translational repressor. In order to study the isolated dimer in a conformation not influenced by capsid interactions, a mutant molecule was crystallized that is defective in capsid ... | Crystallization; RNA Bacteriophage; RNA Hairpin; Translational Repressor | 1995 |

Normann, Richard A. | Visual Neuroprosthetics: Functional Vision for the Blind | Resent progress in materials and microfabrication technologies have allowed researchers to reconsider the prospect of providing a useful visual sense to the profoundly blind. This will be accomplished by electrically stimulating their visual systems via an array of implanted microelectrodes. T... | Visual Neuroprosthetics; Vision; Blindness | 1995-01 |

Gesteland, Raymond F. | Characterization of lysozyme messenger and lysozyme synthesized in vitro | In vitro systems for protein systhesis have been in wide use for about 10 years. In most of the early work protein synthesis was measured by following the incorporation of radioactive amino acids into acid precipitable material. This test cannot distinguish between the synthesis of complete, activ... | Lysozyme Messenger; Lysozyme Synthesized; Protein Synthesis | 1969 |

Normann, Richard A. | Statistical encoding model for a primary motor cortical brain-computer interface | A number of studies of the motor system suggest that the majority of primary motor cortical neurons represent simple movement-related kinematic and dynamic quantities in their time-varying activity patterns. An example of such an encoding relationship is the cosine tuning of firing rate with respect... | Discrete Distribution; LN Model; Neural Decoding; Neuroprosthetics; Sequential Monte-Carlo Filter | 2005 |

Gesteland, Raymond F.; Atkins, John F.; Wills, Norma M. | rRNA-mRNA base pairing stimulates a programmed -1 ribosomal frameshift | Base pairing between the 3' end of 16S rRNA and mRNA is shown to be important for the programmed -1 frameshifting utilized in decoding the Escherichia coli dnaX gene. This pairing is the same as the Shine-Dalgarno pairing used by prokaryotic ribosomes in selection of translation initiators, but for ... | Frameshifting; Escherichia coli; Binding Sites; Base Composition | 1994 |

Gesteland, Raymond F.; Atkins, John F. | Evolutionary specialization of recoding: frameshifting in the expression of S. cerevisiae antizyme mRNA is via an atypical antizyme shift site but is still +1 | An autoregulatory translational shift to the +1 frame is required for the expression of ornithine decarboxylase antizyme from fungi to mammals. In most eukaryotes, including all vertebrates and a majority of the studied fungi/yeast, the site on antizyme mRNA where the shift occurs is UCC-UGA.
