    Description / Table of Contents: Summary The clinical courses of vocal rehabilitation of patients with different degrees of laryngeal paralysis can proceed very differently, but usually do not correspond with the physical changes of glottic function seen on laryngoscopy and stroboscopy. In this study 43 patients with laryngeal paralyses were examined, of whom 28 had regeneration of nerve function. Fifteen did not show any improvement in glottal function. All patients were asked to describe their voices, after which subjective data were compared to objective findings concerning vocal penetrating capacity were found to be valid in reflecting therapeutic effects and for estimating voice capability.
    Notes: Zusammenfassung Die stimmliche Rehabilitation von Patienten mit Larynyparesen unterschiedlichen Ausmaßes verläuft sehr verschieden und häufig nicht in Übereinstimmung mit dem Bild der organischen Veränderung. In der vorliegenden Studie wurden 43 Patienten mit N.-laryngeus-inferior- und N.-laryngeus-superior-Paresen untersucht. Es wurden neben der Glottisfunktion stimmliche Parameter (Sprechstimmlage, Stimmgröße, Stimmumfang, Einschwingphase, Durchdringungsfähigkeit) den subjektiven Einschätzungen der Patienten (stimmliches Wohlbefinden, Belastungsdauer der Stimme) gegenübergestellt. Dabei wird deutlich, daß weitgehend unabhängig vom Regenerationsverhalten der Parese durch gezielte Behandlung eine vom Patienten subjektiv als gut bewertete stimmliche Rehabilitation möglich ist. Als Maß des Therapieerfolgs und Entscheidungshilfe in Fragen der Dauer der Arbeitsunfähigkeit haben sich vor allem die Stimmgröße, die Qualität der Einschwingphase und die Durchdringungsfähigkeit der Stimme geeignet erwiesen.

    A model study of the temporal behaviour of the emission intensity and rotational temperature of the OH Meinel bands for high-latitude summer conditions (1996)

    Notes: Abstract The temporal variation of OH* emission and weighted rotational temperature has been studied for high-latitude summer conditions. Observations for 60°N latitude show OH weighted temperatures that always exceed 145 K even during periods of noctilucent clouds. Using a one-dimensional model the effects in excited OH concentration produced by changes in temperature, eddy diffusion, and water concentration have been analysed. We are forced to conclude that there remains a discrepancy between the OH temperatures predicted by the model and that obtained from OH* measurements. An increase in OH* concentration from June to the beginning of August, followed by a slow decrease during August has been obtained in agreement with the measurements. The 16-day modulation present in the measurements was simulated in a simple manner by varying the temperature in the mesopause region. This variation produces periodic modulations in both OH* concentration and weighted temperature of 16 days. The results show the temperature leading the OH* column concentration by three days. This phase shift is also present in the observations.

    Isotopes, Wool, and Rangeland Monitoring: Let the Sheep Do the Sampling (1998)

    Notes: 3 and C4 plant species consumed by animals. Sheep sample vegetation continuously throughout a year, and as their wool grows it integrates and stores information about their diet. In subtropical and tropical rangelands the majority of grass species are C4. Since sheep prefer to graze, and their wool is an isotopic record of their diet, we now have the potential to develop a high resolution index to the availability of grass from a sheep's perspective. Isotopic analyses of wool suggest a new direction for monitoring grazing and for the reconstruction of past vegetation changes, which will make a significant contribution to traditional rangeland ecology and management. It is recommended that isotopic and other analyses of wool be further developed for use in rangeland monitoring programs to provide valuable feedback for land managers.

    Notes: Abstract 153Sm-EDTMP (ethylenediaminetetra(methylenephosphonic) acid) is of considerable interest as a bone therapeutic radiopharmaceutical but its properties in solution are not yet well characterized. The protonation constants of EDTMP and the formation constants of the complexes of Sm-EDTMP have accordingly been measured potentiometrically by glass electrode titrations at 25°C in 0.15 M NaCl. Six protonation constants (log β011 = 9.638, log β012 = 17.330, log β013 = 23.597, log β014 = 28.636, log β015 = 31.501, log β016 = 32.624) and the formation constants of the [Sm(EDTMP)H-1]6- (log β11-1 = 4.865), [SmEDTMP]5- (log β110 = 12.018), [Sm(EDTMP)H]4- (log β111 = 17.892) and [Sm(EDTMP)H2]3- (log β112 = 23.437) complexes were determined. Computer simulations indicate that the [SmEDTMP]5- and the hydroxy [Sm(EDTMP)H-1]6- species are the major Sm(III) complexes formed in blood plasma, which explains the high degree of localization in the kidney and urine observed in biodistribution studies. Calcium ions are probably the maior competitor for EDTMP in blood plasma. As the presence of secondary skeletal metastases results in a high rate of bone turnover, it is possible that the high concentration of calcium at these sites encourages localization of 153Sm-EDTMP.

    Notes: Abstract  In situ Raman spectroscopy, in combination with energy dispersive spectroscopy, has been used for the first time to determine the identities and locations, at the micron level, of mineral phases present in single chiton teeth that have been extensively mineralized. At the later stages of development the major lateral teeth of the chiton Acanthopleura hirtosa show characteristic spectroscopic evidence for the presence of lepidocrocite (γ-FeOOH), magnetite (Fe3O4), and an apatitic calcium phosphate. Goethite (α-FeOOH) and ferrihydrite (5 Fe2O3·9 H2O), which have been detected previously in teeth at the early stages of mineralization, were not detected in this mature tooth. The spatial distribution of these phases was determined, providing evidence for the presence of a discrete layer of lepidocrocite between the magnetite and apatite regions, illustrating the complexity of the biomineralization process. The technique of laser Raman microscopy is shown to be ideal for the examination of small biomineralized structures in situ, such as chiton teeth.

    Stimmsignalanalysen bei laryngealer Hyperreagibilität (1998)

    Description / Table of Contents: Summary Increased reactions of the laryngeal mucosal membrane can appear after acetylcholine (ACH) inhalation. A red mucous membrane, vocal cord edema, mucus formation, changes in the glottic configuration and (rarely) sub-glottic edema are visible to laryngoscopic observations. The influence on various voice parameters in patients with and without laryngeal hyperreactivity was researched in order to decide the reliability of voice para-meter measurements in clinical practice. Significant variations of the soft phonation index (SPI), the fundamental frequency variation (vFo), the noise-to-harmonic ratio (NHR) and the voice turbulence index (VTI) were examined for their correlations with the observable features of laryngeal hyper-reactivity. A single diagnosis of hyperreac-tivity with voice parameter analysis failed in 50% of the patients examined because of functionalvoice instability and irregularities seen. Only with both laryngoscopy for re-liable discrimination and voice parameter analysis for quantitative registration were findings sufficient for assessing laryngeal hyperreactivity.
    Notes: Zusammenfassung Neben der bekannten bronchialen und nasalen Hyperreaktivität gibt es auch eine laryngeale Manifestationsform. Eine laryngeale Hyperreagibilität ist durch Inhalation mit Acetylcholinlösung provozierbar. Eine überdurchschnittlich reagierende Larynxschleimhaut zeigt bei laryngoskopischer Beobachtung deutliche Veränderungen in Form von Schleimhautrötungen, Stimmlippenödemen, Veränderungen des Glottisspaltes, vermehrter Schleimproduktion und subglottischen Ödemen. Häufig tritt auch eine qualitative Veränderung der Stimme ein, die stimmsignalanalytisch für eine objektive Bewertung der Reaktionslage der Larynxschleimhaut und der Glottis untersucht wird. Verglichen wird der Einfluß der Veränderungen im Larynx auf Stimmparameter bei Probanden mit und ohne sichtbare laryngeale Hyper-reagibilität. Die Stimmsignalanalyse registriert mit ihren Parametern laryngeale Veränderungen nach Acetylcholininhalation, kann aber wegen funktionaler Stimminstabilitäten und Irregulationen nicht zur alleinigen Beurteilung einer laryngealen Hyperreagibilität verwendet werden, deren sicherer Nachweis nur mit Hilfe der Laryngoskopie gelingt.
