    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.

    Notes: The densities of feline epidermal dendritic cells expressing CD18. MHC class II and CD1a antigens were determined for four anatomical locations in 19 cats of European breed in blind conditions. The densities (±SD) of CD1a+ Langerhans cells in the skin of the abdominal wall (269±68 cells/mm2), the back (363±19), the internal side of the ear (572±30) and the external side of the ear (502±32) were significantly different, with young and old animals displaying less stained cells than adults. No significant differences in the mean densities were found with regard to sex, colour or antibody used.

    A thermoresistant strain of feline immunodeficiency virus (FIV) with an altered cytopathic effect and a restricted cell tropism (1998)

    Notes: Summary.  A thermoresistant strain, designated m41, of feline immunodeficiency virus (FIV) was selected after 31 successive passages of chronically infected IRC4 cells at 41 °C. The wild-type virus (wt) which served as a control was cultivated the same number of times at 37 °C. In Crandell feline kidney cells (CrFK), the replication of m41 was similar at 37 °C and 41 °C, whereas wt multiplied only at 37 °C. Furthermore, m41 was more resistant than the wt strain at temperatures ranging from 37 to 56 °C. Syncytia formation was observed with m41 when the CrFK were incubated at 41 °C whereas neither m41 nor wt produced syncytia at 37 °C. The level of replication of wt and m41 on feline lymphoid primary cells at 37 °C was similar. In contrast to wt, m41 was unable to infect bone marrow macrophages. Since one or several mutations in the envelope (env) gene could be involved in changes of cell fusion properties and of cellular tropism, the nucleotide sequence of the env gene derived from wt and m41 respectively was determined. Ten mutations were found in the env gene of m41, thus leading to 9 amino acid modifications in the envelope glycoproteins. These results suggest that structural modifications of the viral envelope proteins are prerequisites for the replication of a thermoresistant FIV strain at elevated temperature and are correlated with the newly acquired viral phenotype.

    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.

    High-resolution, low-voltage SEM for true surface imaging and analysis (1995)

    Notes: Abstract A novel design concept for the electron optical column has been implemented in the realization of a new ultra-high performance SEM. A compound magnetic/electrostatic objective lens is at the heart of the high-performance column: the imaging aberrations of this new lens type decrease with decreasing beam energy. Any beam cross-over between the electron source (Schottky FE-gun) and the sample has been eliminated in order to avoid broadening of the beam energy spread (Boersch effect). A high beam energy is maintained throughout the column regardless of the electron probe energy selected by the operator. This protects the beam against the effect of stray fields and minimizes any loss of beam brightness due to stochastic electron-electron interactions. The new SEM achieves outstanding resolution, particularly at the low beam energies (3 nm achievable at EPE=1 keV). The secondary electrons emitted by the sample are detected with very high efficiency by an internal annular detector situated above the final lens. Due to the low imaging aberration level, a high current can easily be focused in a very small probe, thus making the new SEM ideally suited for high-resolution, quantitative X-ray analysis.
