Capecchi, Mario R. | Removing the vertebrate-specific TBP N terminus disrupts placental beta2m-dependent interactions with the maternal immune system | Mammalian 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 Protein | 2002-07-12 |

Ehleringer, James R. | Carbon isotope discrimination in the C4 shrub Atriplex confertifolia along a salinity gradient | Carbon isotope discrimination (∆) was measured for leaves of Atriplex confertifolia along a salinity gradi~ ent in northern Utah. Over this gradient, the variation of ∆ values was high for a C4 species, and the ∆ values were positively correlated with salinity in both years of the study.

Coley, Phyllis D. | Antifungal depsidone metabolites from Cordyceps dipterigena, an endophytic fungus antagonistic to the phytopathogen gibberella fujikuroi | Among thirty four endophytic fungal strains screened for in vitro antagonism, the endophytic fungus Cordyceps dipterigena was found to strongly inhibit mycelial growth of the plant pathogenic fungus Gibberella fujikuroi. Two new depsidone metabolites, cordycepsidone A (1) and cordycepsidone B (2), w... | 2012 | |

Bastiani, Michael | Pathfinding by neuronal growth cones in grasshopper embryos I. Divergent choices made by the growth cones of sibling neurons | We are interested in how the growth cones of identified neurons navigate in the central nervous system of the grasshopper embryo. The behavior of identified growth cones was observed as a function of developmental time by (i) periodically removing embryos from synchronized clutches of eggs and (i... | Neuropil; Axonal; Cell | 1983 |

Farmer, Colleen G. | Reproduction: the adaptive significance of endothermy | A central theme raised by Angilletta and Sears is that the energetic cost of endothermy is too enormous to be offset by the benefits that thermogenesis could provide for reproduction. Angilletta and Sears suggest that parents would have been better off producing additional offspring with the energy ... | Parental care; Incubation; Metabolism | 2003 |

Beckerle, Mary C. | CRP1, a LIM domain protein implicated in muscle differentiation, interacts with α-actinin | Members of the cysteine-rich protein (CRP) family are LIM domain proteins that have been implicated in muscle differentiation. One strategy for defining the mechanism by which CRPs potentiate myogenesis is to characterize the repertoire of CRP binding partners. | CRP1; Cysteine-rich proteins; Actinin; Protein-protein interactions; LIM domains | 1997 |

Goller, Franz | Inspiratory muscle activity during singing in zebra finches and cowbirds | Singing is produced by an intricate coordination of vocal (syringeal) and respiratory muscles. Expiratory muscle activity is associated with the production of notes and syllables, which are separated by silent intervals, negative air sac pressure, and inspiratory air flow. In order to study the mus... | Minibreath; Expiration; Inspiration | 1997 |

Bastiani, Michael | Developmental expression and biochemical analysis of Conulin, a protein secreted from a subset of neuronal growth cones | In this report, we analyze the developmental pattern of expression of a new grasshopper protein, Conulin, using the monoclonal antibody 7D2 on whole-mount embryos and dissociated neurons. We also have examined its biochemical properties by immunoblot analysis.

Beckerle, Mary C. | Characterization of the interaction between zyxin and members of the Ena/Vasodilator-stimulated Phosphoprotein family of proteins | Zyxin contains a proline-rich N-terminal domain that is similar to the C-terminal domain in the ActA protein of the bacteria, Listeria monocytogenes. We screened the entire amino acid sequence of human zyxin for Menainteracting peptides and found that, as with ActA, proline-rich sequences were the s... | Zyxin; Actin; Listeria monocytogenes; Proline-rich repeats; Cell spreading | 2000 |

Ehleringer, James R. | Carbon isotope ratios in belowground carbon cycle processes | Analyses of carbon isotope ratios (δ13C) in soil organic matter (SOM) and soil respired CO2 provide insights into dynamics of the carbon cycle. δ13C analyses do not provide direct measures of soil CO2 efflux rates but are useful as a constraint in carbon cycle models. In many cases, δ13C analyses... | Below ground processes; Ecosystems; Carbon cycle; Carbon isotope ratio; Ecosystem processes; Global change; Soil organic carbon; Soil organic matter | 2000 |

Potts, Wayne K. | Emigration behavior of Clark's Nutcracker | Eruptive movements of the Clark's Nutcracker (Nucifraga columbiana) were observed during the late summer and fall of 1977, 1978 and 1979 in northern Utah and adjacent states. Over 2,000 emigrating nutcrackers were seen during these periods. Eruptions began in mid to late August, about the time nutcr... | Breeding range; Flocks; Observations | 1981 |

Capecchi, Mario R. | How close are we to implementing gene targeting in animals other than the mouse? | Describes several significant contributions that bring us much closer to extending ‘‘gene targeting'' to mammalian species other than the mouse. Gene targeting now provides the means for creating new strains of mice with mutations in virtually any gene. First, the desired mutation is introduced ... | Cattle; Mutagenesis; Mice; Humans; Ethics, Medical | 2000-02-01 |

Olivera, Baldomero M.; Gray, William Robert; McIntosh, J. Michael | New α-conotoxin which targets α3ß2 nicotinic acetylcholine receptors | We have isolated a 16-amino acid peptide from the venom of the marine snail Conus magus which potently blocks nicotinic acetylcholine receptors (nAChRs) composed of α3ß2 subunits. This peptide, named a-conotoxin MII, was identified by electrophysiologically screening venom fractions against cl... | Conotoxins; a-conotoxin MII; Conus magus | 1996 |

Linton, Matthew J. | Hydraulic conductivity, xylem cavitation, and water potential for succulent leaves of agave deserti and agave tequilana | Axial hydraulic conductivity (Kh) was measured for fresh, dehydrated, and rehydrated leaves of the Crassulacean acid metabolism (CAM) leaf succulents, Agave deserti and Agave tequilana. Dehydration of leaves at 35(o)C for several hours caused Kh to decrease, with a 50% decrease occurring at a leaf w... | Transpiration; Dehydrated; Drought | 2001 |

Adler, Frederick R. | Information collection and spread by networks of patrolling ants | To study how a social group, such as an ant colony, monitors events occurring throughout its territory, we present a model of a network of patrolling ants engaged in information collection and dissemination.

Clayton, Dale H. | Ecoimmunity in Darwin's finches: invasive parasites trigger acquired immunity in the medium ground finch (Geospiza fortis) | Invasive parasites pose a serious threat to native animal populations, because hosts with no history of exposure may lack effective immune defenses. Invasive parasites are a particular threat to small, island populations [1,2]. For example, introduced malaria (Plasmodium relictum) has exacerbated t... | Darwins finches; Ecoimmunity; Acquired immunity; Medium ground finch; Geospiza fortis; Invasive parasites; Novel parasites; Poxvirus avium; Nest flies; Philornis downsi | 2010-01-06 |

Adler, Frederick R. | Do rhinoviruses follow the neutral theory? The role of cross-immunity in maintaining the diversity of the common cold | Over 100 serotypes of rhinoviruses, one of the primary causes of the common cold, co-circulate in the human population. This high diversity makes it effectively impossible to develop a vaccine, even for those at risk of complications due to asthma or cystic fibrosis. | Serotypes; mutation rate; immunodominance | 2006 |

Blair, David F. | Chemical and spectroscopic evidence for the formation of a ferryl Fea3 intermediate during turnover of cytochrome c oxidase | When partially reduced cytochrome c oxidase samples are reoxidized with dioxygen, an EPR-silent dioxygen intermediate, which is at the three-electron level of dioxygen reduction, is trapped at the dioxygen reduction site. The intermediate has novel spectral features at 580 and 537 nm. Combined op... | Cytochrome c oxidase; EPR; Fea3 intermediate; Reduction | 1986 |
