    Notes: Abstract During the 1980s, seismic research suggested that Oregon and the City of Portland had a higher risk of a major earthquake than had previously been assumed. In 1993, the State of Oregon adopted a new version of the Oregon Structural Specialty Code, which changed the designation of western Oregon from seismic zone 2b to seismic zone 3. The City of Portland established a program and a Task Force on Seismic Strengthening of Buildings to recommend actions that would encourage upgrading of city buildings. A survey of adult city residents was conducted in April, 1996 to determine public attitudes and opinions about earthquake risks, management and mitigation of earthquake hazards, priorities for protection by strengthening buildings, evaluations of strategies for informing the public about earthquake risks, and support for specific options the city might take to protect citizens against earthquake events. Social and demographic information on individuals and households was also collected. Respondents provided ratings for a wide range of social and environmental risks, provided information on priorities for strengthening key buildings and infrastructure facilities, and answered hypothetical questions about voting for bond measures to pay for city earthquake-mitigation programs. Respondents recognized significant risk from earthquakes and supported programs to protect people, especially vulnerable residents such as children and the sick. There was strong support for protecting emergency response capabilities. There was much less support for using public funds to reduce the risks associated with privately owned buildings. There were also some strong pockets of resistance to publicly funded mitigation programs in response to the hypothetical bond measures.

    Microtubule gelation-contraction in vitro and its relationship to component a of slow axonal transport (1988)

    Notes: Microtubule proteins, isolated by cycles of assembly, will undergo ATP-dependent gelation-contraction in vitro. A particulate component is present in these preparations, which is required for the gelation-contraction of microtubules assembled from purified tubulin. These particulates contain tubulin, neurofilament, spectrin, MAP2, and other as yet unidentified proteins. The particulates have a microtubule-stimulated ATPase that may be unique and is the likely motor for microtubule gelation-contraction. The basic structural unit of these particulates appears to be a crescent-shaped, or hemispherical, granule about 20 nm in diameter. The particles move along microtubule walls at a rate of about 1 μm. When compared to known physiological phenomena, microtubule gelation-contraction has striking similarities to component a of slow axonal transport (SCa), but displays no relationship to slow component b or to fast transport. On the basis of their similarities in composition, solubility, and rate of movement, we have proposed that the particulates responsible for microtubule gelation-contraction are the insoluble protein complexes, which have been suggested to be the transported component of SCa. We have termed these structures “slow component a particulates” or “SCAPs.” It is probable that similar motile protein complexes exist in cells other than neurons, and we propose the term “dynasome” to describe such structures in general.

    Mouse transition protein 1 is translationally regulated during the postmeiotic stages of spermatogenesis (1989)

    Notes: Transition protein 1 (TP1) is a small basic nuclear protein that functions in chromatin condensation during spermatogenesis in mammals. Here, recently identified cDNA clones encoding mouse transition protein 1(mTP1) were used to characterize the expression of the mTP1 mRNA during spermatogenesis. Southern blot analysis demonstrates that there is a single copy of the gene for transition protein 1 in the mouse genome. Northern blot analysis demonstrates that mTP1 mRNA is a polyadenylated mRNA approximately 600 bases long, which is first detected at the round spermatid stage of spermatogenesis. mTP1 mRNA is not detectable in poly(A)+ RNAs isolated from mouse brain, kidney, liver, or thigh muscle. mTP1 mRNA is translationally regulated in that it is first detected in round spermatids, but no protein product is detectable until approximately 3 days later in elongating spermatids. In total cellular RNA isolated from stages in which mTP1 is synthesized, the mTP1 mRNA is present as a heterogeneous class of mRNAs that vary in size from about 480 to 600 bases. The shortened, heterogeneous mTP1 mRNAs are found in the polysome region of sucrose gradients, while the longer, more homogeneous mTP1 mRNAs are present in the postmonosomal fractions.
