The results show that the RNA polymerase I antibodies do not interfere with normal mitotic progression or the early steps of nucleologenesis, i.e. , the aggregation of nucleolar material into prenucleolar bodies. However,they inhibit the telophasic coalescence of the prenucleolar bodies into the chromosomal nucleolar organizer regions, thus preventing the formation of new nucleoli. These prenucleolar bodies show a fibrillar organization that also compositionally resembles the dense fibrillar component of interphase nucleoli . We conclude that during normal nucleologenesis the dense fibrillar component forms from preformed entities around nucleolar organizer regions, and that this association seems to be dependent on the presence of an active form of RNA polymerase I.}, language = {en} } @incollection{Scheer1987, author = {Scheer, Ulrich}, title = {Contributions of electron microscopic spreading preparations ("Miller-spreads") to the analysis of chromosome structure}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-39625}, publisher = {Universit{\"a}t W{\"u}rzburg}, year = {1987}, abstract = {No abstract available}, subject = {Eukaryonten / Chromosom}, language = {en} } @article{ScheerRaska1987, author = {Scheer, Ulrich and Raska, I.}, title = {Immunocytochemical localization of RNA polymerase I in the fibrillar centers of nucleoli}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-39618}, year = {1987}, abstract = {No abstract available}, language = {en} } @article{Scheer1987, author = {Scheer, Ulrich}, title = {Structure of lampbrush chromosome loops during different states of transcriptional activity as visualized in the presence of physiological salt concentrations}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-39304}, year = {1987}, abstract = {Lampbrush chromosomes of amphibian oocytes were isolated in the presence of near-physiological salt concentrations, to preserve their native state, and studied by electron microscopy of ultrathin s~dions.

During decreasing transcriptional activity and reduced packing density of transcripts, the chromatin axis first condensed into nucleosomes and then into an approximately 30 nm thick higher order chromatin fiber.

These exoproteins derive from the two gram-negative bacteria Escherichia coli and Aeromonas hydrophila and from the gram-positive pathogen Listeria monocytogenes. The hemolysin of E. coli is determined by an 8-kilobase (kb) region that includes four clustered genes (hlyC, hlyA, hlyB, and hlyD). This hemolysin determinant is part either of large transmissible plasmids or of the chromosome. The genes located chromosomally are found predominantly in E. coli strains that can cause pyelonephritis and/or other extraintestinal infections. A detailed analysis of the chromosomal hly determinants of one nephropathogenic E. coli strain revealed the existence of specific, large chromosomal insertions 75 kb and lOO kb in size that carry the hly genes but that also influence the expression of other virulence properties, i.e., adhesion and serum resistance. The direct involvement of E. coli hemolysin in virulence could be demonstrated in several model systems. The genetic determinants for hemolysin (cytolysin) formation in , A. hydrophila (aerolysin) and L. monocytogenes (listeriolysin) are less complex. Both cytolysins seem to be encoded by single genes, although two loci (aerB and aerC) that affect the expression and activity of aerolysin have been identified distal and proximal to the structural gene for aerolysin (aerA). Cytolysin-negative mutants of both bacteria were obtained by site-specific deletion and/or transposon mutagenesis.

The dissociation of the radioiodinated label (1251-AHPIA) from isolated rat fat cells was incomplete after UV irradiation, leaving about 20°/o of irreversible specific binding. Such covalent labelling of the receptor led to a concentration-dependent reduction of cellular cyclic AMP levels. This persistent effect of covalent labeHing occurred with an IC50 value of 9 nM, as compared to an IC50 value of 0.9 nM for the direct reduction of cyclic AMP Ievels by the ligand. The difference in the IC5o values can be explained by assuming spare receptors. This hypothesis was verified in binding studies using [ 3HJPIA as a radioligand. R-AHPIA inhibited binding of [3H)PIA to intact fat cells with a K1 value of about 20 nM, which is about 20 tim es high er than the corresponding IC50 value of cyclic AMP reduction. These data show that the A1 receptor is activated according to the occupancy theory.

In a first system, precursor, nitrous acid and NBP were present simultaneously. All amino acids tested, except glutamic acid and glutamine, gave positive results. The reactivities spanned more than three orders of magnitude, with the aromatic amino acids and methionine the most active; two primary amines, tryptamine and histamine, were also strongly reactive. All guanidines tested, except the amino acid arginine, gave negative results. A second system consisted of two phases: NBP was added only after destruction of residual nitrite and adjustment of the pH to neutrality. This system was useful for the study of ureas, which are stable in acid but not in neutral media. The range of responses covered more than two orders of magnitude. Most amino acids and primary amines also gave positive results, but could be assessed only after analysing the kinetics of the competing reactions and choosing appropriate reaction times. In a third system, Salmonella typhimurium strain TA1OO replaced NBP. Representatives of the class of amino acids, ureas, the primary amine tryptamine, and aniline became higbly mutagenic upon nitrosation.

Thr ecological separation of 19 carrion inscet species (adults and some of their larvae) was investigated at rabbit carcasses in North Bavaria (FRG) referring to 4 niche dimensions. In the (1.) macrohabitats (forest - clearing) the distribution of saprophageous beetle larvae was mainly considered, for (2.) seasonality the differential abundance of blow flies (Colliphoridae). (3.) The stages of decay were correlated with the temperature dependent development of blow fly maggots affecting the abundance of competing saprophageous beetles and of carnivors preying upon maggots of different size classes. By using ( 4.) microhabitats (spatial subdivision of a carcass) as further niche dimension, the dustering of speries using similar food resources was domonstrated in a niche overlap dendrogram. 2. The quantitative effect of predators on blow fly maggots was investigated both in field and laboratory experiments. Predation upon maggots rcduces their scramble competition, resulting in a higher pupal weight. Thus, the reproductive succcss of the blow flies seems to be buffered by the developmental flexibility of the calliphorids. The numerical effect of predators and parasitoids on the blow fly pupae was also quantified. 3. In a case study on the staphylinid beetle, Aleochara curtula, we investigated the diffenntial abundance of sexes. The ratio at which the males and females arrive at the carcass is balanced. Here the beetles feed and copulated. Females depart into the vicinity of the carrion much earlier than males, thus shifting the sex ratio to a maale bias. In the surroundings the females deposit their eggs, and the parasitoid first instar larvae search for scattered blow fly pupae. The temporal and spatial distribution of both sexes of A. curtula is thus not only affected by the food allocation of the adults, but a.lso by limiting resources of mating end egg laying sites as well as larval hosts.}, subject = {Aask{\"a}fer}, language = {en} } @article{DickneiteSchorlemmerSedlaceketal.1987, author = {Dickneite, G. and Schorlemmer, H.

It is concluded that TRH may have a physiological rote in centrat cardiovascular regulation.}, subject = {Thyreotropin-Releasinghormon}, language = {en} } @article{FoersterSchartl1987, author = {Foerster, Wolfgang and Schartl, Manfred}, title = {Karyotype and isozyme patterns of five species of Aulonocara REGAN, 1922}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-86774}, year = {1987}, abstract = {No abstract available.}, subject = {Aulonocara}, language = {en} } @article{OpwisGoldSchneider1987, author = {Opwis, K. and Gold, A. and Schneider, Wolfgang}, title = {M{\"o}glichkeiten der Kreuzvalidierung von Strukturgleichungsmodellen}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-87377}, year = {1987}, abstract = {Die Beurteilung der Angemessenheit theoretischer Oberlegungen auf der Grundlage statistischer Hypothesentests ist f{\"u}r die empirische Forschung von zentraler Bedeutung. Im Mittelpunkt der Arbeit stehen die mit der Testung von multivariaten Strukturgleichungsmodellen (LISREL-Modelle) verbundenen Probleme. Zu Beginn wird das LISREL-Modell unter den Aspekten der simultanen Analyse von Kovarianzund Mittelwertstrukturen und der Modelltestung diskutiert. Anschließend werden anhand eines Illustrationsbeispiels aus der p{\"a}dagogisch-psychologischen Forschung verschiedene Vorgehensweisen der Kreuzvalidierung einander gegen{\"u}bergestellt und an empirischen Daten demonstriert. Es zeigt sich, daß die Obernahme exakter numerischer Parameterwerte sowohl aufgrund inhaltlicher wie auch formaler Argumente unangemessen streng erscheint. Diese Einsch{\"a}tzung kann empirisch belegt werden, indem eine Approximation von Intervallrestriktionen vorgenommen wird.}, subject = {Kreuzvalidierung}, language = {de} } @article{Hommers1987, author = {Hommers, Wilfried}, title = {Anti-Typen: Zur psychologischen Validit{\"a}t eines methodischen Konstrukts der Konfigurationsfrequenzanalyse}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-43437}, year = {1987}, abstract = {Das Konzept des Anti-Typus wird theoretisch und empirisch-analytisch untersucht.
