    Effect of type and amount of comonomer on the properties of four copolymers of ethylene (1966)
    Stamford, Conn. [u.a.] : Wiley-Blackwell

    Notes: The plastics industry is now coming to realize that copolymers are unique thermoplastics which have broad areas of application. It is believed that ethylene-methyl acrylate copolymers of 2 melt index may be extrusion coated to paper by a cap-coat process or by use of a chill roll with an adhesive coating. Copolymers of ethylene and vinyl monomers can be made into film by the same methods used for polyethylene. Methyl acrylate and methyl methacrylate copolymers may be processed on a wide range of molding equipment. Table VII in the article gives a list of applications for each polymer, along with expected physical properties.

    Selected reaction monitoring during gas chromatography/mass spectrometry of eicosanoids (1988)
    Chichester : Wiley-Blackwell
    Biological Mass Spectrometry 16 (1988), S. 409-413

    ISSN: 1052-9306

    Topics: Chemistry and Pharmacology
    Notes: Gas chromatography/electron capture negative ion mass spectrometry of eicosanoids, as pentafluorobenzyl (PFB) ester, methyl oxime (where applicable), trimethylsilyl (TMS) ether derivatives, is reported using a double-focusing instrument of trisector configuration. Sub-picogram detection limits were observed for prostaglandins E1, E2 and F2α during selected ion monitoring (SIM) of [M — PFB]- ions. Selected reaction monitoring (SRM) of [M — PFB]- → [M — PFB — TMSOH]-, occurring in the first field-free region, was of modest sensitivity, reflecting the stability of the [M - PFB]- ions. The leukotriene B4 (LTB4) derivative was successfully analyzed by SIM at the low-picogram level. In this instance, the fragmentation [M — PFB]- →[M — PFB — TMSOH] occurred in high yield in the first field-free region. The advantageous improvement in selectivity of detection that may be achieved with SRM was evident during the analysis of a serum extract for LTB4.

    Notes: The effect of 30-49 wt-% nitrile group content on the properties of copolymers is demonstrated. The nitrile is furnished by either acrylonitrile or methacrylonitrile. The exceptional resistance of such high nitrile content resins to the passage of gases and of solvents is shown and variations therein demonstrated for different comonomers. Transparent, tough, grafted polymers of good color are described which retain these properties. These qualities, combined with low second-order transition temperatures and adequate heat deflection temperatures, provide polymers of interest wherever containment and barrier are desired. Bottles, thermoformed containers, etc., could benefit from the use of some of the polymers described.

    Use of gas-liquid chromatography in the analysis of rigid polyurethane foam polyols (1969)
    New York, NY [u.a.] : Wiley-Blackwell
    Journal of Applied Polymer Science 13 (1969), S. 1297-1307

    Notes: Detailed characterization of the low molecular weight polyols used as intermediates in rigid polyurethane foam production has not been feasible to date. Gas-liquid chromatography of the trimethylsilyl ether derivatives of the polyols now offers a more complete picture of polyol composition, particularly with regard to the molecular weight distribution. The data may be interpreted on a semiquantitative basis. The study of processing variables in polyol manufacture, detection of impurities and analysis of unknown polyols or those based on mixed initiators may all be facilitated by use of this GLC technique.

    Study of early sheath development using static nongliding implants (1974)

    Notes: Clinical studies will permit only small sections of tendon sheaths to be removed for biopsy at restricted levels as the sheaths were to be used for tendon grafting. In active gliding programs, biopsy has been limited to small sheath sections in immediate relation to the distal or proximal anastomosis where gliding motion may be induced or minimal. In the passive gliding programs, biopsy has been limited to the most proximal segments where considerable folding of the sheath occurs or cul-de-sac buckling of the implant may produce irritation.As these were the only practical clinical sources of sheath sections for biopsy and study, the authors felt that a comparison study of sheath development in animals would broaden our understanding in humans. With this objective in mind, three canine laboratory studies were carried out where, for pure purposes of investigation, entire sheath sections were removed at designated time intervals for study.The flexible implants were well accepted, affording the opportunity to observe development of early sheaths in a controlled connective tissue environment, free from the stress of joint motion.The semi-rigid implants showed equal acceptance in side-by-side tissue level of the same dog as the flexible implant. This influenced changes in artificial tendon development from extrusion to the more exacting mold fabrication. It seemed evident that the degree of increase in stiffness of the new artificial tendons to gain a superior surface for gliding and increased strength would not change tissue acceptance providing flexibility was maintained.The cellular response in this study did not seem to represent a foreign body phenomena but an orderly acceptance of the soft tissue environment to the smooth surface of the inert implant.It is concluded that this study confirmed in animals the clinical findings of Mayer, Bunnell, Milgram, and Carroll.The consistent orderly development of the new sheaths formed in response to the static implants is impressive. The authors believe the appearance of these histologic sections are likely correlations with the development of new sheaths around the Hunter Tendon Prosthesis during the three-four week postoperative period when the hand is resting in a functional dressing.

    Notes: In sheep, chronic arterial cannulation with Silastic has led to thrombus formation and to intimal fibroplasia of a type not previously reported. Concurrent infection resulted in septic embolization to the brains and eyes on the same side as the cannulated vessels. The histopathology is described in detail.

    Characterization of human skin fibroblast extracellular proteins by two-dimensional polyacrylamide gel electrophoresis (1988)
    Weinheim : Wiley-Blackwell
    Electrophoresis 9 (1988), S. 343-351

    ISSN: 0173-0835

    Topics: Biology , Chemistry and Pharmacology
    Notes: Human skin fibroblasts secrete over 50 proteins into the culture medium. In this paper these are characterised using two-dimensional polyacrylamide gel electrophoresis and peptide mapping of proteins metabolically labelled in the presence and absence of tunicamycin. Thirty of these proteins have been shown to be N-glycosides, 4 are O-glycosides and 10 are not glycosylated. Of the major proteins, groups 1-4 have previously been shown to be fibroblast specific. Peptide mapping and tunicamycin treatment has identified that groups 1 and 2, and 3 and 4 are closely related and that groups 1 and 3 arise by N-glycosylation of 2 and 4, respectively. The unglycosylated precursor forms of several other proteins have also been identified. This approach to the analysis of protein secretion provides an abundance of information on many proteins simultaneously and can be used to assess the changes in protein secretion associated with development, and to identify extracellular growth factors and other regulatory proteins.
