    Acute infantile hemiplegia in a patient with propionic acidaemia (1990)

    Notes: Abstract A 10-month-old girl with mild developmental delay became hemiplegic after seizures. Cranial CT scan and magnetic resonance imaging (MRI) revealed no lesions related to vascular diseases, but brain atrophy on the right side was remarkable. Digital subtraction angiography showed slightly decreased visualization of peripheral branches of the right medial cerebral artery. Propionic acidaemia was diagnosed on the basis of high plasma levels of propionic acid and its metabolites and the elevated urinary excretion of these acids. With therapy, the levels of these acids fell, and her left hemiplegia disappeared 3 months later.

    Appearance of peroxidase isozymes in floral-initiated shoot apices of Pharbitis nil (1992)
    Copenhagen : Munksgaard International Publishers
    Physiologia plantarum 86 (1992), S. 0 
    Details

    Topics: Biology
    Notes: A novel biochemical assay system for detecting the early stage of flowering is reported. Peroxidase isozymes in shoot apices of Pharbitis nil plants that had been exposed to flower-inducing or non-inducing conditions were analyzed by isoelectric focusing in polyacrylamide gels and activity staining for peroxidase. Several isozymes with pH 8.5–8.8 appeared for the first time 7 days after the beginning of short-day treatment, but not after nightbreak (non-inducing) treatment. When shoot tips were cultured in vitro, these same isozymes also appeared after short-day treatment but not after night-break treatment. The extent of the appearance of these isozymes was reduced by exposure to high or low temperature during the inductive dark period and removal of cotyledons after the inductive dark period. Such treatments also reduced the extent of flowering. The appearance of an isozyme with pH 8.5 was more closely correlated with flowering than that of the other isozymes. From these results, the appearance of this peroxidase isozyme in shoot apices is discussed as a biochemical marker of flowering in intact plants and in cultured shoot tips.

    Temporomandibular joint osteoarthritis: a comparative clinical and tomographic study pre- and post-treatment (1994)
    Oxford, UK : Blackwell Publishing Ltd

    Notes: Nineteen patients with definite and suspected temporomandibular joint (TMJ) osteoarthritis participated in this study. All patients were treated by dental care including bite plane therapy. By comparing the pre-treatment clinical symptoms and TMJ tomograms with those post-treatment, efficacy of the dental treatment applied for these patients has been assessed.Since TMJ pain and limitation of mouth opening were considerably improved in almost all patients post-treatment, this suggests that the clinical prognosis of TMJ osteoarthritis can be favourable. On the other hand, radiographic changes post-treatment were variable. The longitudinal changes found in the TMJ tomograms were classified into four types. The frequency of Type 2 and Type 3, which indicate the occurrence of TMJ remodelling during the observation period, was fairy high (20 TMJs and 14 patients).

    Film structure and magnetic properties of ferromagnetic amorphous Bi2O3-Fe2O3-PbTiO3 films prepared by rf-reactive sputtering (1991)

    Notes: Amorphous-like oxide films of the Bi2O3-Fe2O3-PbTiO3 ternary system prepared by rf-reactive sputtering exhibit ferromagnetism and ferroelectricity simultaneously well above room temperature. In this paper, we have investigated the relation between the film structure and the magnetic properties of the films by means of x-ray diffractometry, transmission electron microscopy, magnetization measurement with a vibrating-sample magnetometer, and Mössbauer spectroscopy. The film composition used in the study is 0.16Bi2O3-0.74Fe2O3-0.10PbTiO3, which attains the maximum magnetization in this ternary system. It is revealed that ferromagnetism originates from the amorphous part in the films.

    Ferromagnetic amorphouslike oxide films of the Fe2O3-Bi2O3-PbTiO3 system prepared by rf-reactive sputtering (1991)

    Notes: In this paper, the magnetic properties of ferromagnetic oxide films of the ternary Fe2O3-Bi2O3-PbTiO0 system prepared by rf-reactive sputtering are presented. As-sputtered films deposited at a substrate temperature below 400 °C are amorphous and behave paramagnetically. Amorphous films like these whose composition corresponds to the perovskite solid solution of BiFeO3 -PbTiO3 become crystalline with a perovskite structure on annealing in air, but no distinct spontaneous magnetization appears. On the contrary, in certain compositions in the Fe2O3 -Bi2O3 -PbTiO3 system, the samples retain a glassy (or amorphouslike) state even when the samples were annealed at around 600 °C. Also a spontaneous magnetization appears at room temperature. The maximum room-temperature saturation magnetization 4πMs achieved in this system is 1.67 kG with the composition 0.74Fe2O3 -0.16Bi2O3 -0.10PbTiO3. Experiments imply that the amorphous state is essential for establishment of strong ferromagnetism in the sputtered oxide films. Mössbauer spectroscopy and x-ray photoelectron spectroscopy were performed to examine the microscopic properties of the films that lead to ferromagnetism. The optical transmissivity and magneto-optical Faraday effect of the films are also discussed.

    Depth selective Mössbauer spectroscopic study of Fe3O4 epitaxial films (1990)

    Notes: Several (111) oriented 56Fe3O4 films containing a 5-A(ring)-thick 57Fe3O4 probe layer at or below the surface were grown epitaxially on the α-Al2O3 (0001) surface by a reactive vapor deposition method. Conversion electron Mössbauer spectroscopy was applied at 6, 78, and 300 K by using a recently developed helium-filled proportional counter. The well-crystallized surface has been found to be surprisingly stable even in air as characterized by the Mössbauer parameters that are almost the same as for the bulk. Moreover, the Verwey transition was detected clearly even in the 5-A(ring)-thick surface layer. However, the ferrous components seem to have changed their Mössbauer parameters probably because of their sensitivity to any crystalline field modifications in the surface. Generally speaking, the quality of epitaxial Fe3O4 films is very high: Any unusual surface state, if present, is confined in a shallow depth of ≤ 5 A(ring).

    Magnetic anisotropy by ferromagnetic particles alignment in a magnetic field (1990)

    Notes: Magnetic and optical properties of films composed of ferromagnetic fine particles aligned in a magnetic field were investigated. The spin-coated films were prepared by using a solution of magnetite fine particles dissolved in water-diluted polyvinyl alcohol (PVA) on glass substrates, and followed by drying at 80 °C and solidifying at 200 °C in a magnetic field. Linear-chain clusters of magnetite particles were formed in a considerably weak field below 1 kOe, which give rise to magnetic and optical uniaxial anisotropies. Both properties vary depending on preparation conditions such as the particle concentration, the viscosity of the solution, and the field strength during drying.
