    Notes: Abstract In axisymmetric flows, we show that the laser beam deviation technique can be associated with an Abel inversion calculation in order to give the local density and its gradients. We report density profile measurements in the different regions (zone of silence and barrel shock) of nitrogen and argon supersonic free jets near the nozzle exit. Three different nozzle geometries have been tested at different stagnation pressures. Results are compared to calculations obtained by the method of characteristics.

    Notes: Summary Humic acid-type polymers (melanins) synthesized in culture media by the fungi Aspergillus glaucus, Eurotium echinulatum, Hendersonula toruloidea, Stachybotrys atra and Aspergillus sydowi were analysed for elemental composition, functional group content, infrared (IR) and electron spin resonance (ESR) properties. Results were discussed in comparison with range values referred for soil humic acids. The fungal polymers showed significant differences in carboxyl and nitrogen content and C/H atomic ratios, reflecting a different degree of condensation (aromaticity) among the various samples. IR analysis gave evidence of: (a) the predominant aromatic character of melanins from A. glaucus, E. echinulatum and H. toruloidea; (b) the high content of aliphatic and olefinic components of S. atra melanin; (c) the typical presence of amide bonds in the nitrogen-richest melanins from A. sydowi and H. toruloidea; and (d) the generally low amount of free carboxyl groups, which often appeared involved in hydrogen bonds. ESR spectra showed that all the melanins studied contained appreciable concentrations of organic free radicals of prevailing semiquinonic nature and of the same order of magnitude commonly measured in humic acids from soil and other sources. The free electron concentration was shown to be directly related to the C/H atomic ratio and to the degree of aromaticity shown by IR analysis. This indicated that the highest free radical content in the melanins from E. echinulatum and A. glaucus was associated with the highest presence of condensed aromatic structures. Humic acid-type polymers synthesized by soil fungi may, therefore, contribute to the total free radical content of soil humic substances and play important roles in all reactions involving free radicals in soils and related environments.

    Einfluß von Montmorillonit auf die Bildung von Biomasse und Stoffwechselzwischenprodukten durch einige Mikroorganismen (1970)

    Description / Table of Contents: Zusammenfassung Die Zugabe von Montmorillonit zu Kulturlösungen verschiedener Mikroorganismen ergab bei Schüttel- oder Standkulturen meist eine Steigerung der Biomasse und einen erhöhten Nährstoffverbaruch. Diese Steigerung wurde besonders unter aeroben Verhältnissen und in den ersten Wachstumsphasen beobachtet. Die Bildung von Äthanol durch S. cerevisiae bzw. Citronensäure durch A. niger war beschleunigt, aber nicht wesentlich erhöht. Manometrische Messungen mit S. cerevisiae ergaben in Abhängigkeit von der Montmorillonit-Konzentration einen höheren RQ. Die Relation der Biomasse zu verbrauchter Glucose deutet auf eine bessere Ausnutzung der Energiequelle für synthetische Prozesse hin.
    Notes: Summary The addition of montmorillonite to stationary and shake-cultures of various microorganisms usually increased total biomass formation and accelerated the utilization of nutrients. These effects were noted especially under aerobic conditions and during the initial growth phases. The formation of ethanol by S. cerevisiae and citric acid by A. niger was accelerated, but not significantly increased. manometric measurements with S. cerevisiae showed a higher RQ which increased with increasing montmorillonite concentrations. The relation between biomass formation and glucose consumption indicates a more efficient utilization of the energy source for synthetic processes.

    Respiratory symptoms and pulmonary function in 871 miners according to Pi phenotype: A longitudinal study (1988)
    Springer

    Keywords: Epidemiology ; Occupational pathology ; Chronic bronchitis Iron miners ; Protease inhibitor (Pi) phenotype

    Topics: Medicine
    Notes: Abstract Pi phenotype was determined and α1 protease inhibitor (α1Pi) was measured in 871 iron-ore miners examined twice at five years interval. A questionnaire on respiratory symptoms was administered and lung function tests: spirometry (VC, FEV1.0), measurements of the residual volume (RV/TLC) and of the CO diffusion (FuCO), were carried out by the same medical and technical team, using the same apparatus. There were no differences in age, lenght of employment or smoking habits among the three Pi Phenotype groups: M (90:03%), MS (7.1%), MZ (2.8%). The prevalence of clinical symptoms at the initial survey and the incidence of symptoms between the 2 surveys were not related to Pi Phenotype groups. However a significantly steeper decline of FEV1.0/VC was observed in the α1Pi partially deficient groups MS and MZ (−3.9%) compared with the non-deficient group (−1.8%). No significant difference was observed for VC, RV /TLC and FuCO. This finding suggests that an intermediate deficiency of α1Pi may be related to a slight but statistically significant impairment of a lung function in occupational conditions.

    Description / Table of Contents: Résumé Le système Pi a été étudié chez 132 individus d'une population Bantoue du Zaïre. Le phénotype MM est le plus fréquent, comme dans toutes les autres populations étudiées jusqu'àce jour. Un nouvel allèle, PiL est décrit ici, notamment par les techniques bidimensionnelles, et sa transmission est démontrée. Dans ce petit échantillon, l'absence de l'allèle PiZ, responsable d'affections graves (emphysèmes chez l'adulte et cirrhoses chez l'enfant), est à noter.
    Abstract: Zusammenfassung Die Pi-Typen von 123 Bantu aus Zaire wurden bestimmt. Der Phänotyp MM ist wie bei anderen Populationen der häufigste. Es wird ein neues Allel PiL beschrieben und seine Vererbung nachgewiesen. Das Allel PiZ kommt in der relativ kleinen Population nicht vor.
    Notes: Summary The Pi phenotypes of 132 individuals of a Bantu population living in Zaire were examined. The MM phenotype was the most common, as in all other populations studied up to now. This paper deals with a new allele, PiL, identified by two-dimensional techniques, and its mode of inheritance is demonstrated. In this small sample, there is a conspicuous absence of PiZ, the allele responsible for such severe diseases as emphysema in adults and cirrhosis in children.

    Description / Table of Contents: Résumé Un allotype lent de l'albumine a été trouvé chez un donneur de sang. L'étude familiale confirme la liaison du locus de l'albumine et du système Gc. Parmi les 16 sujets porteurs du trait en simple dose, aucune manifestation pathologique ne semble associée. L'un des individus porte l'allèle lent en double dose, ce qui serait le premier cas d'une telle variété cathodique de l'albumine.
    Abstract: Zusammenfassung Bei einem Blutspender wurde ein langsamer Allotyp des Albumins gefunden. Der Zusammenhang zwischen Albumin-Locus und Gc-System wurde durch Familien-studien bestätigt. Bei 16 Patienten, Träger dieses Faktors in einfacher Dosis, scheint keine Beziehung zu pathologischen Beziehungen zu bestehen. Eine der Personen besitzt das langsame Allel in doppelter Dosis, was der erste Fall einer solchen kathodischen Albumin-Varietät wäre.
    Notes: Summary A slow albumin allotype was found in a blood donor. The albumin locus-Gc system relationship is confirmed by family studies. There seems to be no association with pathological manifestations among the 16 subjects bearing this factor in simple dose. One of the individuals possesses the slow allele in double dose, a fact which would be the first case of such a cathodic albumin variety.

    Notes: Summary Mouse hepatitis virus 3 (MHV-3) is highly hepatotropic in sensitive mice. Temperature-sensitive mutants (ts mutants) induced by N-methyl-N′-nitrosoguanidine and 5-fluorouracil were isolated. Twelve mutants which were able to induce the formation of syncytia at 33°C but not at the restrictive temperature (39.5°C) were selected for detailed study. No viral RNA synthesis was detected after infection at the restrictive temperature with six of the mutants (RNA−) whereas six others were RNA+, although they displayed RNA synthesis which was generally reduced. No differences have been detected in the size of the genome or the viral-intracellular RNA species found in wild type virus or ts mutant infected cells at permissive temperature. The pattern of virus-induced proteins analyzed after immunoprecipitation by SDS-PAGE was similar in wild type virus and RNA+ mutant infected cells at 39.5°C. Complementation experiments between ts mutants enabled us to distinguish five groups. Three of the groups contained RNA− mutants and two of them RNA+. Plaques made by mutants in one group displayed characteristic features that distinguished them from the wild type.
