    Notes: Abstract The effects of acrylamide intoxication on the numbers of granule and Purkinje cells and the volume of Purkinje cell perikarya have been evaluated with stereological methods. The analysis was carried out in the cerebella of rats that had received a dose of 33.3 mg/kg acrylamide, twice a week, for 7.5 weeks. The total numbers of cerebellar granule and Purkinje cells were estimated using the optical fractionator and the mean volume of the Purkinje cell perikarya was estimated with the vertical rotator technique. The volumes of the molecular layer, the granular cell layer and the white matter were estimated using the Cavalieri principle. The mean weight of the cerebellum of the intoxicated rats was 7   % lower than that of the controls rats (2P = 0.001). The numbers of the Purkinje cells and granule cells were the same in both groups, but the mean volume of the perikarya of the Purkinje cells in the intoxicated rats was 10.5   % less than that of the control group (2P = 0.004). The volume of the granular cell layer was reduced by 15   % (2P = 0.006) but there were no differences in the volumes of the molecular layer and the white matter in the intoxicated and control animals.

    Improved current transport properties of post annealed Y1Ba2Cu3O7−x thin films using Ag doping (1996)

    Notes: The influence of Ag doping on the transport properties of Y1Ba2Cu3O7−x thin films prepared by Y, BaF2, and Cu co-evaporation and optimized ex situ post annealing has been investigated. Both undoped and Ag doped films have values of Tc above 90 K, but Jc (77 K) is highly dependent on the nominal thickness (tnom) of the as-deposited film. For undoped films with tnom≤300 nm Jc (77 K) ((very-much-greater-than)106 A/cm2) decreases monotonically with increasing film thickness. Above 300 nm Jc (77 K) decreases rapidly to values below 5×105 A/cm2. Ag doped films with tnom≥200 nm have higher Jc (77 K) values than those of undoped films. Ag doped films have a maximum in Jc (77 K) around 250 nm. As for the undoped films, there is a large decrease in Jc (77 K) for Ag doped films with tnom≥300 nm. It was found that the higher values of Jc (77 K) for the Ag doped films were due to a better epitaxial growth of the YBCO compound. The low values of Jc (77 K) for both undoped and Ag doped single layer films with tnom≥300 nm were found to be due to the absence of 1–2–4 inclusions in these films. Based on these findings high Jc (77 K) films with tnom(approximately-greater-than)300 nm were grown by successive deposition and annealing of films with tnom〈300 nm on top of each other. A 2×150 nm undoped film was found to have a Jc (77 K) value of 4, 1×106 A/cm2. This is almost a doubling of the Jc (77 K) value as compared to the value for the 300 nm single layer undoped film (2,2×106 A/cm2). Ag doped double layer films of 2×150 nm and 2×215 nm had comparable Jc (77 K) values (5,8×106 and 5,6×106 A/cm2, respectively). In comparison with the undoped 2×150 nm film Jc (77 K) is thus further increased (by about 50%) when doping with Ag. © 1996 American Institute of Physics.

    Dissociative sticking of CH4 on Ru(0001) (1999)
    College Park, Md. : American Institute of Physics (AIP)

    Notes: In this study the CH4 dissociation probability on Ru(0001) is found for various translational and vibrational energies. The absolute sticking values are determined from King and Wells experiments and carbon uptake curves. The carbon amount is determined from the recombination signal of carbon with oxygen obtained after the beam exposure when heating in an oxygen atmosphere. The measured sticking coefficient of CH4 is strongly enhanced both by increasing the translational and the vibrational energy of the CH4 molecule. A model is applied to the data and an estimate of the thermal activation energy for CH4 dissociation is found to be in good agreement with previous bulb experiments. © 1999 American Institute of Physics.

    Modification of Ni(111) reactivity toward CH4, CO, and D2 by two-dimensional alloying (1996)
    College Park, Md. : American Institute of Physics (AIP)
    The Journal of Chemical Physics 104 (1996), S. 7289-7295

    Notes: Alloying Au into the outermost atomic layer of Ni(111) significantly alters the physical and chemical properties of the surface. The reactivity is investigated by the use of seeded supersonic molecular beams of CH4 and it is found that the nobleness of Au reduces the overall reactivity toward CH4. This is accounted for in an ensemble model resolving the sticking probability on Ni atoms having different nearest neighbor surroundings. Although a mean field description of site distributions is found to be a very good approximation it is improved by using experimentally determined ensemble statistics from STM images. The strong influence of the vibrational temperature on the sticking coefficients of CH4 vs translational energy on the pure Ni(111) is also demonstrated. Desorption energies of CO and D2 is observed to decrease approximately 25–30 kJ/mole as the coverage of Au is increased from 0.0 to 0.7 ML. In TPD spectra of deuterium saturated surface alloys a new clearly resolved desorption state is observed at 180–220 K with maximum intensity around θAu=0.3–0.4 ML. This state is clearly related to chemisorption sites involving both Au and Ni. A site model based on mean field statistics adequately accounts for the appearance of this state. The effect of Au is also evident in the TPD spectra of CO saturated Au/Ni(111) surface alloys where the saturation coverage decreases and new structure develops. © 1996 American Institute of Physics.

    RITODRINE IN THE TREATMENT OF PRETERM (1980)
    Oxford, UK : Blackwell Publishing Ltd

    Notes: In a randomized trial, three alternative schemes of treatment of preterm labour with ritodrine (long infusion, short infusion, and intramuscular injection) were compared with standard treatment by bed rest and sedatives. None of the ritodrine treatments were found to be better in postponing delivery than the standard treatment. However, the Bishop scores of the patients in the standard treatment group tended to be lower than of the patients treated with ritodrine. Moreover, all cases of congenital malformation and polyhydramnios occurred in the patients treated with ritodrine. The incidence of respiratory insufficiency was significantly higher in infants of mothers treated with ritodrine. The mean birth weight was highest in the standard treatment group.

    EFFECT OF BROMOCRIPTINE ON THE PREMENSTRUAL SYNDROME. A DOUBLE-BLIND CLINICAL TRIAL (1977)

    Notes: Twenty-one patients suffering from the premenstrual syndrome were each studied during three menstrual cycles. After a control cycle, bromocriptine and placebo were given during the luteal phase of the cycle in a random double-blind cross-over manner, each patient serving as her own control. The dosage of bromocriptine was 2·5 mg twice daily. Serum prolactin levels were found to be equal during the follicular and luteal phases, except when reduced by bromocriptine. Serum progesterone and oestradiol-17-β were within normal ranges, and did not change during treatment. Medication considerably improved all the premenstrual symptoms, but mastodynia was the only one where bromocriptine was significantly better than the placebo.
