    Basal cell carcinomas in mice overexpressing sonic hedgehog (1997)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-05-02
    Description: Mutations in the tumor suppressor gene PATCHED (PTC) are found in human patients with the basal cell nevus syndrome, a disease causing developmental defects and tumors, including basal cell carcinomas. Gene regulatory relationships defined in the fruit fly Drosophila suggest that overproduction of Sonic hedgehog (SHH), the ligand for PTC, will mimic loss of ptc function. It is shown here that transgenic mice overexpressing SHH in the skin develop many features of basal cell nevus syndrome, demonstrating that SHH is sufficient to induce basal cell carcinomas in mice. These data suggest that SHH may have a role in human tumorigenesis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Oro, A E -- Higgins, K M -- Hu, Z -- Bonifas, J M -- Epstein, E H Jr -- Scott, M P -- AR39959/AR/NIAMS NIH HHS/ -- New York, N.Y. -- Science. 1997 May 2;276(5313):817-21.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Department of Dermatology, Stanford University School of Medicine, Stanford, CA 94305-5427, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9115210" target="_blank"〉PubMed〈/a〉

    Notes: Rapid technological advancements have contributed to the increasing application of adhesives. Because of these accomplishments, because of continuing materials research and process development activities, and because of their inherent advantages, adhesives have a great potential for the future. Requirements for the future impose a severe challenge on developmental capabilities. More severe structural requirements and environmental conditions may be expected. Because of increasing complexity and costs, there are requirements for significantly higher orders of reliability and lower fabrication costs. Improvements in bonding processes and development of comparatively new techniques are desirable. Test methods require further development and standardization - especially nondestructive methods. Continuing work in collecting and reporting pertinent information, especially on properties and design parameters for adhesive bonding is helping to advance the utilization of adhesives. Current trends indicate that adhesives are progressing from the realm of “art” to science, a factor which should substantially aid in advancing the future potential for adhesives.

    Studies on the chemical syntheses and on the characteristics of polyaniline derivatives (1995)

    Notes: Syntheses of parent polyaniline and methyl, methoxy, and ethoxy ortho-substituted polyanilines were performed using the conventional chemical methodology and monitored using the new open-circuit-potential (Voc) profile technique. The intermediate pernigraniline oxidation state was identified and isolated at the Voc maximum (A) during the conventional chemical synthesis of poly(o-methoxyaniline) in the emeraldine oxidation state. The introduction of the substituent on the aniline ring leads to longer polymerization times and lower Voc values. Syntheses in the presence of two different monomers in solution were also investigated and showed preferential polymerization of the monomer with the lowest Voc potential. All polymers produced were characterized by elemental analysis, gel permeation chromatography, UV-VIS spectroscopy, and cyclic voltammetry. The influence of the substituent on the Voc profile and on the polymer characteristics are rationalized in terms of steric and electronic effects. © 1995 John Wiley & Sons, Inc.

    Fabrication of high modulus films by solid state rolling (1986)
    Stamford, Conn. [u.a.] : Wiley-Blackwell

    Notes: Solid state rolling of semicrystalline polymers represents a high speed process for producing oriented, high modulus films, tapes, and sheets. The important process variables include roll temperature, thickness of initial sheet, roll speed, take-up tension, roll diameter, and initial morphological state of the polymer. Roll temperature controls both the extent of maximum deformation and the rate of rolling. A minimum temperature exists for each polymer below which the orientation process is sharply limited. This condition is similar to the limitation present in the hydrostatic extrusion process, in which the alpha crystallization temperature limits the orientation process. Roll speeds as high as 20 m/min have been realized. It is apparent that film thickness and thickness reduction ratio have a strong effect on the ultimate rolling rate. The process, as currently practiced, is adiabatic, and therefore, heat transfer limited. The take-up tension influences the extant of orientation in the amorphous phse of of the polymer. This in turn affects its thermal and chemical stability. The effect of roll diameter is to limit the extent of thickness reduction by causing roll-film slippage when the roll dianmeter to thickness reduction ratio is below some as yet undetermined value. The initial morphological state of the polymer affects the amount of crystalline deformation possible, the surface texture of the rolled film, and the tear resistant of the oriented film.
