Large males differentiate at a size va:rying between 25 and 38 mm; intermediate males, between 21 and 25 mm. Under competition, !arge males exhibit an elaborate courtship display, whereas small males show only a sneak-chase behavior. Intermediate males adapt their tactics to the respective competitors. However, all malemorphs can switch from courtship display to sneak-chase behavior. In large mating groups with four males of different size and five or six virgin females, large dominant a-males as weil as small subordinate \(\delta\)-males did not produce any offspring. Unexpectedly, all progeny were sired exclusively by the intemediate subordinate ß- and \(\gamma\)-males. Breeding experiments with the three male morphs can best be explained by a model of Y -linked genes for small and !arge size which are both suspended by the activity of an autosomal recessive repressor responsible for the development of intermediate males. The dominant allele of the recessive repressor, in either its homoorits heterozygous state, activates the Y-chromosomal genes for !arge or small size, respectively. Accordingly, intermediate males may produce male offspring of all size classes, depending on the presence of either the Y-linked gene or the autosomal repressor.}, subject = {Physiologische Chemie}, language = {en} } @article{Engels1994, author = {Engels, Bernd}, title = {Detailed study of the configuration selected multi-reference configuration interaction method combined with perturbation theory to correct the wave function}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-59019}, year = {1994}, abstract = {A reliable prediction of the isotropic hyperfine coupling constant A\(_{iso}\) is still a difficult task for ab initio calculations. In previous studies, the configuration selected multireference configuration interaction method in combination with perturbation theory to correct the wave function (MRCI/ B\(_K\)) yielded accurate isotropic hyperfine coupling constants very economically. The present study gives a detailed analysis of the MRCI/ B\(_K\) method based on the X\(^2 \pi\) state of CH as a test case. Furthermore, a comparison to various other methods such as Maller-Ptesset perturbation theory and the coupled cluster approach is made. The success of the MRCI/ B\(_K\) method in predicting isotropic hyperfine coupling constants is explained in terms of the inßuence of higher than double excitations.}, subject = {Organische Chemie}, language = {en} } @article{EinfeldtHeinkeBehringeretal.1994, author = {Einfeldt, S. and Heinke, H. and Behringer, M. and Becker, Charles R. and Kurtz, E. and Hommel, D. and Landwehr, G.}, title = {The growth of HgSe by molecular beam epitaxy for ohmic contacts to p-ZnSe}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-38001}, year = {1994}, abstract = {The structural properties of HgSe grown by molecular beam epitaxy (MBE) are investigated for different lattice mismatches to the substrate and various growth conditions. The growth rate is shown to depend strongly on the growth temperature above lOO°C as well as on the Hg/Se flux ratio. It has been found that the crystalline perfection and the electrical properties are mainly determined by the layer thickness, especially for the growth on highly lattice mismatched substrates. Changes in the surface morphology are related to growth parameters. Differences between the electrical behavior of MBE-grown and bulk HgSe are discussed. The electrical properties of HgSe contacts on p-ZnSe are investigated as a function of different annealing procedures.}, language = {en} } @article{EcksteinMuellerBuchholtzUlrichs1994, author = {Eckstein, V. and M{\"u}ller-Buchholtz, W. and Ulrichs, Karin}, title = {Reaction patterns of natural xenophile antibodies in human sera with pancreatic islet cells and porcine lymphocytes}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-44742}, year = {1994}, abstract = {No abstract available}, subject = {Chirurgie}, language = {en} } @article{DunsterSchneiderSchauliesLoeffleretal.1994, author = {Dunster, L.M. and Schneider-Schaulies, J{\"u}rgen and L{\"o}ffler, S. and Lankes, W. and Schwartz-Albiez, R. and Lottspeich, F. and ter Meulen, V.}, title = {Moesin: a cell membrane protein linked with susceptibility to measles virus infection}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-54931}, year = {1994}, abstract = {Measles virus is a highly contagious virus causing acute and persistent diseases in man, the receptor of which is still not weil characterized. We have isolated a monoclonal antibody (mAb), designated mAb 119, which specifically inhibits measles virus infection of susceptible celllines in a dosa-dependent manner. This antibody precipitates a protein with an apparent molecular mass of 75 kDa from 1251 surface-labeled cells and its epitope is present on human peripheral blood mononuclear cells, human celllines, and the African green monkey cellline Vero. Affinity chromatography of detergent-solubilized cell membrane proteins over a Sepharose column with covalently bound mAb 119 led to the partial purification of the 75-kOa protein. Preincubation of measles virus with this affinity-purified protein inhibited measles virus infection dose dependently. Aminoacid microseq,uencing of this protein revealed its identity with the human membrane-organizing extension spike protein moesin, a protein intra- and extracellularly associated with the plasma membrane of cells. Subsequently, an antibody raised against purified moesin (mAb 38/87) was also found to specifically inhibit measles virus infection of susceptible cells and confirmed our data obtained with mAb 119. Our data suggest that moesin is acting as a receptor for measles virus.}, subject = {Immunologie}, language = {en} } @article{DittrichThoenenSendtner1994, author = {Dittrich, Falk and Thoenen, Hans and Sendtner, Michael}, title = {Ciliary neurotrophic factor: pharmacokinetics and acute-phase response in rat}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-42639}, year = {1994}, abstract = {No abstract available}, language = {en} } @article{DemchukMuellerOschkinatetal.1994, author = {Demchuk, E. and Mueller, T. and Oschkinat, H. and Sebald, Walter and Wade, R.

Structural data show that the human growth hormone (hGH) forms a complex with a homodimeric receptor and that hGH is a member of a class of hematopoietins possessing an antiparallel 4-a-helix bundle fold. Mutagenesis experiments suggest that electrostatic interactions may have an important influence on hormonereceptor recognition. In order to examine the specificity of hormone-receptor complexation, an analysis was made of the electrostatic potentials of hGH, interleukin-2 (IL-2), interleukin-4 (IL-4), granulocyte colony-stimulating factor (G-CSF), granulocyte-macrophage colony-stimulating factor (GM-CSF), and the hGH and IL-4 receptors. The binding surfaces of hGH and its receptor, and of IL-4 and its receptor, show complementary electrostatic potentials. The potentials of the hGH and its receptor display approximately 2-fold rotational symmetry because the receptor subunits are identical. In contrast, the potentials of GM-CSF and IL-2 Iack such symmetry, consistent with their known high affinity for hetero-oligomeric receptors. Analysis of the electrostatic potentials supports a recently proposed hetero-oligomeric model for a high-affinity IL-4 receptor and suggests a possible new receptor binding mode for G-CSF; it also provides valuable information for guiding structural and mutagenesis studies of signal-transducing proteins and their receptors.}, subject = {Biochemie}, language = {en} } @article{DandekarArgos1994, author = {Dandekar, Thomas and Argos, Patrick}, title = {Amiloride-sensitive epithelial Na\(^+\) channel is made of three homologous subunits}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-29734}, year = {1994}, abstract = {No abstract available}, language = {en} } @article{DandekarArgos1994, author = {Dandekar, Thomas and Argos, P.}, title = {Folding the main chain of small proteins with the genetic algorithm}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-29847}, year = {1994}, abstract = {No abstract available}, language = {de} }
