    Notes: Abstract The adult population of a large mental hospital was screened for tardive dyskinesia (TD). Approximately 11% of the hospital population showed signs of TD; females and the elderly were over-represented in the TD group. A representative sample of those with TD was selected and a control (non-TD) patient was chosen to match each of the TD subjects in age, sex, length of hospitalization, diagnosis, and race. The charts of these subjects were searched for any indices of brain damage and the complete psychotropic medication history was recorded. There was no difference between the TD and controls in the amount of psychotropics ingested, in the duration of administration, in the kinds of drugs, or in the organicity history. Women as a group, however, tended to have more polypharmacy than men. The role of neuroleptics in TD is discussed as well as other possible etiological factors.

    Clozapine in tardive dyskinesia (1978)

    Notes: Abstract Clozapine, which has had limited clinical testing in the U.S.A., was evaluated in 12 chronic schizophrenic patients with tardive dyskinesia. Its antipsychotic activity was again demonstrated and it suppressed the symptoms of tardive dyskinesia with a marked rebound occurring in these symptoms when it was withdrawn; there was no rigidity or other Parkinsonian symptoms. However, out of a total of 12 patients, neutropenia (800 and 1120) occurred in two patients, convulsions in one patient, marked withdrawal effects in three patients, and a hypotensive collapse with atrial fibrillation in one patient. If these adverse effects are confirmed in a larger sample size, then despite the novel desirable effects of clozapine it would seem unlikely that it will gain widespread or routine use1.

    Deanol in the treatment of tardive dyskinesia (1977)
    Springer
    Psychopharmacology 52 (1977), S. 257-261

    Topics: Medicine
    Notes: Abstract Ten hospitalized chronic psychotic patients with symptoms of tardive dyskinesia were given deanol and placebo, each for 8 weeks following a double blind, crossover design. No psychotropic agents were administered during the trial. Improvement occurred in all patients during the first treatment phase regardless of which drug the patients received; seven patients were on deanol and three on placebo during this time. The possible reasons for this decrease were discussed. It was concluded that deanol may have contributed to the decline but that its effect on the disorder was not dramatic.

    Notes: A theoretical and experimental investigation of a water jet impinging on a melting solid surface has been carried out. Ice, octane, p-xylene, and olive oil served as the meltable solid materials, comprising a Prandtl number range of 5 to 2 800. An available laminar stagnation flow model was utilized to describe melting heat transfer in the jet impingement region. Melting rate measurements were found to agree quite well with the values predicted with this model.

    Convective instabilities in porous media with through flow (1976)

    Notes: The stability of a thermally stratified, saturated porous media through which mass is being ejected is considered theoretically. The stability parameter is a flow modified D'Arcy-Rayleigh number and is a function of a single scalar variable, the dimensionless through-flow strength. Results of both linear and energy theory are given, and it is seen that the fluid can lose stability by either a buoyantly driven mode or by a continuous analogue of the Saffman-Taylor mode.

    Free-radical polymerization of vinylferrocene. I. Kinetics (1975)
    New York : Wiley-Blackwell
    Journal of Polymer Science: Polymer Chemistry Edition 13 (1975), S. 1049-1070 
    Details

    Topics: Chemistry and Pharmacology
    Notes: The polymerization of vinylferrocene in benzene at 60°C in the presence of 2,2′-azobisisobutyronitrile has been studied. Densities and apparent densities were determined and rates of polymerization measured dilatometrically. The results show that vinylferrocene does not obey normal vinyl polymerization kinetics. Thus the rate of polymerization is proportional to the mean monomer and mean initiator concentrations both raised to a power of 1.1, and the degree of polymerization is independent of the initiator concentration. The polymerization reaction also has a high overall activation energy of 139 kJ/mole. The unusual kinetics are due to a monomolecular termination of the polyvinylferrocene chain radical which is also intermolecular with respect to the chain radical. Termination occurs by an intramolecular electron transfer reaction from a ferrocene nucleus to the growing chain radical which deactivates the chain radical and produces a polymer molecule containing a high spin Fe (III) complex. The presence of this species has been confirmed by Möussbauer and ESR spectroscopy. The rate constant for termination is between 3 and 60 sec-1. Intramolecular electron transfer has not been previously observed in vinyl polymerizations. The term “intralectran” is suggested to describe this new type of termination. Vinylferrocene readily undergoes transfer to monomer (with a transfer constant equal to about 8 × 10-3) and to polymer, but not to benzene.

    Notes: Nylon 66 [poly(hexamethylene adipamide)] and Nomex [poly(m-phenylene isophthalamide)] were metalated by using solutions of sodium in liquid ammonia. Metalation of the Nomex polymer was also carried out by using sodium naphthalene in tetrahydrofuran. The metalated polymers were then reacted with acrylonitrile monomer to yield the corresponding anionic graft copolymers. The heterogeneous nature of these reactions is discussed in relation to the structure of the graft copolymers.

    Notes: Styrene has been polymerized thermally at 60.5°C, without added initiator, in the presence of ferrocene. An increase in the rate of polymerization was observed, but the degree of polymerization remained constant. Evidence of ferrocene-styrene interaction is presented, and a kinetic scheme involving propagation with styrene in such an interaction state is proposed to account for these findings. Various kinetic parameters defined by this scheme have been evaluated.

    Notes: The kinetics of the AIBN-initiated homopolymerization of vinylferrocene in dioxane has been investigated at 60°C. The rate of polymerization was found to be dependent on the monomer concentration to a power 0.97 and on the initiator concentration to a power 0.42. The overall activation energy for polymerization over the range 50-80°C was 84 kJ/mole. Analysis of polymer molecular weight data gave the chain transfer constant to monomer Cm as 1.2 × 10-2 and analysis of both rate and molecular weight data gave kp/(kt)0.5 as 2.36 × 10-2 dm1.5/mole0.5-sec0.5. Mössbauer and ESR spectra indicated the absence of Fe(III)-containing paramagnetic species in the polyvinylferrocene formed under these conditions.

    Free-radical polymerization of vinylferrocene. II. Spectroscopic and physical properties (1976)

    Notes: The spectroscopic and physical properties of poly(vinylferrocene) prepared by free-radical polymerization in benzene are discussed. The results obtained in these studies are in accord with the kinetic analysis of the polymerization reactions in benzene. ESR spectroscopy shows that the polymer is paramagnetic and contains a species which is identified by Mössbauer spectroscopy as an ionically bound complex of Fe(III) in a high spin (3d5) configuration. The concentration of this species is shown to be dependent upon kinetic parameters. Magnetic susceptibility measurements show that the polymer does not contain any oxidized ferromagnetic impurities. Infrared spectroscopy indicates that the polymer contains vinylidene groups. The presence of these groups is explained by chain transfer to monomer followed by reinitiation. Ultraviolet spectroscopy also suggests the presence of unsaturation in the polymer. Gel-permeation chromatography indicates that poly(vinylferrocene) is branched even at low conversions. The effect of transfer reactions and the intramolecular electron transfer termination of the chain radical on the structure of poly(vinylferrocene) is discussed. The glass transition temperature and thermal stability of the polymer are also examined.
