    Carcinogenicity examination of betel nuts and piper betel leaves (1979)

    Notes: Summary A dry powder of betel nuts, piper betel leaves and lime was administered to rats. Epidermal thickening was frequently observed in the upper digestive tracts of rats in groups fed the betel nut diet mixed with lime and the betel leaves diet, and a forestomach papilloma was seen in 1 rat given betel leaves diet. These epidermal changes were scarcely seen in rats given either betel nut or normal diet alone.

    Cytochemical changes in lactate dehydrogenase isoenzymes in human brain tumours (1984)
    Springer
    Acta neurochirurgica 71 (1984), S. 243-253 
    Details
    ISSN: 0942-0940
    Keywords: Brain tumours ; LDH isoenzyme ; cytochemistry

    Topics: Medicine
    Notes: Summary The lactate dehydrogenase (LDH) isoenzyme patterns in benign and malignant brain tumours were determined by means of electrophoresis of the cell extracts and selective cytochemical stain of the smears. The LDH isoenzyme distribution of the cell extracts showed a pronounced cathodal shift in the malignant gliomas and metastatic carcinomas. Normal brain tissues and histologically benign gliomas, however, showed an anodal pattern with a dominance of the H-type LDH. Schwannomas and meningiomas had a midzone isoenzyme pattern with a dominant LDH3 fraction. Pituitary adenomas usually showed the LDH pattern similar to that of the normal cerebrum. The LDH M fraction could be cytochemically verified using an inhibitory effect by 2.6 M urea in staining. Astrocytomas grades 3–4 and metastatic carcinomas were characterized by loss or marked reduction of stainability by urea treatment, while astrocytomas grades 1–2 and oligodendrogliomas were resistant to urea inhibition.

    Annulate lamellae in prolactin-secreting pituitary adenomas (1983)
    Springer
    Acta neuropathologica 61 (1983), S. 10-14 
    Details
    ISSN: 1432-0533
    Keywords: Annulate lamellae ; Prolactin ; Prolactinoma ; Pituitary neoplasma ; Pituitary gland
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Summary Electron-microscopic examination revealed the presence of annulate lamellae in four of five prolactinomas. All the patients examined were 24–30-year-old women who had suffered from amenorrhea and galactorrhea for 3–5 years. Serum levels of prolactin were 114–4,700 ng/ml. The tumors removed by a transsphenoidal approach were 4–23 mm in diameter and showed the ultrastructural features of sparsely granulated prolactinoma. Analysis in correlation with clinical and laboratory data revealed that the annulate lamellae were found in rapidly growing prolactinomas. This is the fifth report on pituitary adenomas with annulate lamellae.

    Electrochromic properties of the n-heptyl viologen-ferrocyanide system (1984)
    Springer
    Journal of applied electrochemistry 14 (1984), S. 323-327 
    Details
    ISSN: 1572-8838
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology , Electrical Engineering, Measurement and Control Technology
    Notes: Abstract Electrochromic properties of the mixed solution of n-heptyl viologen dibromide (HV), Fe(CN) 6 4− and NaH2PO2 or KBr were investigated by cyclic voltammetry and the transparency-time relation. When Fe(CN) 6 4− is added to a HV solution the mixture colours violet without inputting any voltage. However, the colour fades gradually by further addition of NaH2PO2, and the transparency of the mixture increases with addition of larger amounts of NaH2PO2. The same effect was observed by addition of KBr to the HV-Fe(CN) 6 4− solution. The input voltage required for the electrochromism of HV is lowered considerably by addition of Fe(CN) 6 4− , when NaH2PO2 or KBr plays a role in controlling the colouringerasing phenomena. The HV-Fe(CN) 6 4− -KBr system showed some HV ‘residue’ in the cyclic voltammogram on an indium-tin oxide (ITO) electrode, while no such HV ‘residue’ was observed in the HV-Fe(CN) 6 4− -NaH2PO2 system. The HV-Fe(CN) 6 4− -NaH2PO2 system is superior in colouring-erasing reproducibility and in response time to the HV solution or the HV-Fe(CN) 6 4− system.

    Analytic study of chaos of the tent map: Band structures, power spectra, and critical behaviors (1983)
    Springer
    Journal of statistical physics 31 (1983), S. 279-308 
    Details
    ISSN: 1572-9613
    Keywords: Chaos ; mapping ; invariant measure ; ergodicity ; band structure of chaos ; power spectrum of chaos ; critical behavior ; scaling law ; Frobenius-Perron operator

    Topics: Physics
    Notes: Abstract Chaotic behaviors of the tent map (a piecewise-linear, continuous map with a unique maximum) are studied analytically throughout its chaotic region in terms of the invariant density and the power spectrum. As the height of the maximum is lowered, successive band-splitting transitions occur in the chaotic region and accumulate to the transition point into the nonchaotic region. The timecorrelation function of nonperiodic orbits and their power spectrum are calculated exactly at the band-splitting points and in the vicinity of these points. The method of eigenvalue problems of the Frobenius-Perron operator is used. 2 m−1 critical modes, wherem = 1,2, 3, ..., are found which exhibit the critical slowing-down near the 2 m−1-band to 2 m -band transition point. After the transition these modes become periodic modes which represent the cycling of nonperiodic orbits among 2 m bands together with the periodic modes generated by the preceding band splittings. Scaling laws near the transition point into the nonchaotic region are investigated and a new scaling law is found for the total intensity of the periodic part of the spectrum.
