    Notes: A novel method was developed to fabricate corrugation for a λ/4-shifted distributed feedback (DFB) laser. Mechanically ruled grating patterns were transferred photolithographically to the surface of an InP substrate. The resultant λ/4-shifted DFB laser operated in a single longitudinal mode at the Bragg wavelength.

    Notes: A varied line-spacing plane grating monochromator is installed at an undulator beamline BL-19B of the Photon Factory. Small contribution of aberrations to image sizes at a focal plane of the varied line-spacing plane grating is calculated with use of an optical path function. The largest resolving power obtained from a ray tracing is estimated to be 4600 at a photon energy of 1239.85 eV and 10 000 at 91.2 eV. Gas absorption spectra show the similar extent of resolution obtained by the ray tracing. A high brightness with a high resolution may be realized in this monochromator. © 1996 American Institute of Physics.

    Notes: We report the second known case of yolk sac tumour of the external auditory canal, occurring in an eight-month-old girl. The excised tumour demonstrated histopathological and immunohistochemical features identical to those of yolk sac tumours of gonadal origin. The tumour was aneuploid by flow cytometry. The patient received chemotherapy post-operatively and has had no evidence of disease 13 months after surgery.

    Angiosarcoma with dermal melanocytosis (1989)
    Oxford, UK : Blackwell Publishing Ltd

    Notes: We report a case of angiosarcoma and dermal melanocytosis occurring simultaneously in the same lesion. We examined the primary and 2 metastatic lesions. Histopathologically, the anaplastic angiosarcoma cells had a tendency to form irregularly shaped small cavities. Immunohistochemically, they were strongly reactive with Ulex europaeus agglutinin (UEAI) stain. The mid and deep dermis of the same lesion had spindle or elongated slender melanocytes containing melanin granules. The melanocytes were positive with S-100 protein stain. Ultrastructurally, pinocytotic vesicles, fine filaments, and Weibel-Palade body-like dense granules were observed in the cytoplasm of angiosarcoma cells. Dermal melanocytes had external lamina and melanosomes in various stages. The melanocytes showed no similarity to the neoplastic tumor cells and there was no apparent intermediate form between the 2 kinds of cells. The etiological implications of dermal melanocytosis with a tumor of vascular origin are discussed.

    Influence of Temperature and Time on Cooking Kinetics of Potatoes (1985)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of food science 50 (1985), S. 0

    Notes: To study cooking kinetics, slices (6 mm thick, 30 mm diameter) of 3 potato varieties were treated in water at 90°, 100° and 110°C for varying times. Sensory, chemical and physical properties were investigated. Changes during cooking at constant temperature were mathematically described by a 0 order (texture, taste) and a 1st order (shear force, dry matter, pectin, soluble amylose, cell size) equation. The starch content remained constant. Temperature dependence of the rate constant could always be described by a first order equation. The z-values, which are necessary to calculate Cvalue for practical heat treatments, could be determined. Correlations established between kinetics of different properties showed that behavior of certain potato properties may be predicted by shear-force measurement.

    Influence of the Composition of Potatoes on Their Cooking Kinetics (1985)

    Notes: A previous study of three potato varieties indicated that shear force measurement may be used to predict the behavior of certain potato properties during cooking. To verify this hypothesis and to confirm other previous findings, slices (6 mm thick, 30 mm in diameter) of 21 potato varieties were thermally treated in water at 100°C. Mathematical expressions were assessed, and coefficients were determined to describe the kinetic behavior of the varieties.

    CHOLINERGIC NEUROMODULATION BY ATP, ADENOSINE AND ITS N6-SUBSTITUTED ANALOGUES IN GUINEA-PIG ILEUM (1985)
    Oxford, UK : Blackwell Publishing Ltd
    Clinical and experimental pharmacology and physiology 12 (1985), S. 0

    Notes: 1. The effects of ATP, adenosine and N6-substituted adenosines, adenosine receptor agonists, on the twitch contraction of guinea-pig ileum evoked by transmural stimulation were evaluated.2. Adenosine and ATP produced an immediate and concentration dependent inhibition of the twitch, IC50 being 1.1 × 10−5 mol/l and 1.2 × 10−5 mol/l, respectively.3. N6-l-phenylisopropyl adenosine (L-PIA), N6-cyclohexyl adenosine (CHA) and N6-allyl adenosine also induced inhibitions which were gradual and persistent, IC50 being 2.6 × 10−8, 2.7 × 10−8 and 5.4 × 10−7 mol/l, respectively.4. Dipyridamole (10−7 mol/l), an adenosine uptake inhibitor, markedly augmented the inhibition evoked by adenosine and ATP, but not that by three N6-substituted adenosines, while theophylline (10−4mol/l) almost completely antagonized the inhibitory effects of all purine compounds. IC50 value of adenosine in the presence of dipyridamole (5 × 10−7 mol/l) was shifted to the left about 50 times from the control, whereas that of L-PIA was virtually unchanged.5. Tissue-medium ratios indicating uptake of [H]adenosine, [3H]ATP and [3H]CHA into the segment were 3.23 (s.e.m. =0.59), 3.59 (s.e.m. =0.78) and 0.41 (s.e.m. =0.04), respectively.6. These results suggest that not only adenosine and ATP but also these N6-substituted adenosines are potent agonists for the PI receptor, implying a similarity between PI and A, receptor in a functional role and these purine compounds may thereby modulate cholinergic neurotransmission by altering adenylate cyclase activity.

    A morphological study off a thyroid carcinoma in a medaka, Oryzias latipes (Temminck & Schlegel) (1996)

    Notes: A large mass protruding beyond the left operculum was found in an adult male medaka, Oryzias latipes (Temminck & Schlegel). Histologically, the mass was mainly composed of thyroid follicles measuring up to 292 μm in diameter. The follicular epithelium consisted of cuboidal or squamous cells. The follicles lacked colloidal material in the lumen. The thyroid tissue infiltrated into the kidney. Electron microscopically, the tumour cells were characterized by dilation and vesiculation of rough endoplasmic reticulum, which extended throughout the cytoplasm, and an irregular outline of the nucleus. Mitotic figures and partly degenerate cells were frequently observed. Based on the above features, the tumour was diagnosed as a follicular carcinoma of the thyroid, the first reported case in the medaka.

    Notes: We describe two patients with lesions clinically resembling pseudoxanthoma elasticum and histologically exhibiting focal elastosis. with normal-appearing elastic fibres in the mid- and deep dermis. We consider that these skin lesions represent a previously undescribed entity, whose pathogenesis appears to be related to the ageing process.
