Bastiani, Michael | Pathfinding by growth cones in the central nervous system of the grasshopper embryo | In the grasshopper embryo the morphological development of individually identified neurons can be traced prior to the onset of axonogenesis on through maturity (eg., Goodman and Spitzer, 1979). The behavior of individual growth cones can be characterized in their natural environment as they extend t... | | 1982-06-03 |

Bastiani, Michael | Pathfinding by neuronal growth cones in grasshopper embryo: III. Selective affinity of the G growth cone for the P cells within the A/P fascicle | The growth cone of the G neuron selectively fasciculates upon specific axon bundles in a stereotypic sequence as it navigates through the developing central nervous system of the grasshopper embryo. It turns and extends anteriorly in the contralateral neuropil of the second thoracic ganglion at a s... | Axon; Filopodia; Neuropil | 1984 |

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 |

Bastiani, Michael | Pathfinding by neuronal growth cones in grasshopper embryos: II. Selective fasciculation onto specific axonal pathways | In the previous paper (Raper, J. A., M. Bastiani, and C. S. Goodman (1983) J. Neurosci. 3: 20-30) we showed that the growth cones of two sibling neurons, the G and C cells, follow the same route in the developing grasshopper neuropil until they reach a stereotypic choice point. Here their growth con... | Neurons; Axons; Neuropil | 1983 |

Bastiani, Michael | Pathfinding by neuronal growth cones in grasshopper embryos: IV. The effects of ablating the A and P axons upon the behavior of the G growth cone | In the companion paper (Bastiani, M. J., J. A. Raper, and C. S. Goodman (1984) J. Neurosci. 4: 2311-2328), we show that as the G growth cone reaches its choice point and turns anteriorly on the A/P fascicle, its filopodia demonstrate selective affinity for the A/P fascicle as compared to the other a... | Labeled pathway; Anterior extension; Fascicle | 1984 |

Gesteland, Raymond F. | Pattern of protein synthesis in monkey cells infected by simian virus 40 | After infection of several permanent monkey cell lines by simian virus 40 (SV40), four additional protein bands can be detected by simple sodium dodecyl sulfate-polyacrylamide gel electrophoresis of whole-cell extracts.

Capecchi, Mario R. | Patterns of integration of DNA microinjected into cultured mammalian cells: evidence for homologous recombination between injected plasmid DNA molecules. | We examined the fate of DNA microinjected into nuclei of cultured mammalian cells. The sequence composition and the physical form of the vector carrying the selectable gene affected the efficiency of DNA-mediated transformation.

Ehleringer, James R. | Patterns of local and nonlocal water resource use across the western U.S. determined via stable isotope intercomparisons | In the western U.S., the mismatch between public water demands and natural water availability necessitates large interbasin transfers of water as well as groundwater mining of fossil aquifers. Here we identify probable situations of nonlocal water use in both space and time based on isotopic compari... | | 2014-01-01 |

Adler, Frederick R. | Patterns of patch rejection in size-structured populations: beyond the ideal free distribution and size segregation | We examine optimal patch allocation strategies in a population structured by size or some other characteristic. By treating size-specific differences among patches as limiting factors, we create a single framework to analyse foraging for two resources, foraging in the presence of predators and fo... | Foraging-predation trade-off; Optimal foraging; Size structure | 2001 |

Hansen, Mark S.; Coffin, Cheryl M.; Capecchi, Mario R. | Pax3:Fkhr interferes with embryonic Pax3 and Pax7 function: implications for alveolar rhabdomyosarcoma cell of origin. | To investigate the role of the translocation-associated gene Pax3:Fkhr in alveolar rhabdomyosarcomas, we generated a Cre-mediated conditional knock-in of Pax3:Fkhr into the mouse Pax3 locus. Exploring embryonic tumor cell origins, we replaced a Pax3 allele with Pax3:Fkhr throughout its expression do... | Neuroprogenitor; Embryogenesis | 2004-11-01 |

Olivera, Baldomero M.; Gray, William Robert | Peptide toxins from Conus geographus venom | The biochemical characterization of three highly toxic peptides from the venom of the marine snail Conus geographus is described in this report. These peptides cause their potent activity by inhibition of the postsynaptic terminus of the vertebrate neuromuscular junction.

Capecchi, Mario R. | Personal view of gene targeting | Gene targeting provides the means for creating strains of mice with mutations in virtually any gene.1 First, the desired mutation is introduced into a cloned copy of the chosen gene by standard recombinant DNA technology. The mutation is then transferred to the genome of a pluripotent mouse embryo-d... | | 1995 |

Coley, Phyllis D.; Kursar, Thomas A. | Pests vs. drought as determinants of plant distribution along a tropical rainfall gradient | Understanding the mechanisms that shape the distribution of organisms can help explain patterns of local and regional biodiversity and predict the susceptibility of communities to environmental change.
