Molekularbiologische und biochemische Untersuchungen zum bakteriellen Naturkautschuk-Abbau, sowie Charakterisierung eines dazu befähigten Bakteriums
(2001-06-29)As a natural product, natural rubber (cis-1,4-polyisoprene) is subjected to a continuous biological process of degradation in the biosphere. For this reason it is astonishing that the exact ... -
Molekularbiologische und Röntgenmikroskopische Charakterisierung der Heterochromatinproteine des Nematoden Caenorhabditis elegans
(2001-12-12)The nematode C. elegans was the first multicellular organisms whose genome was completely sequenced (The C. elegans Sequencing Consortium, 1998). This model organism is highly eligible for ... -
Molekularbiologische Untersuchungen zu zentralnervösen Alterungsprozessen der Reproduktionsfunktion in der weiblichen Ratte
(2003-01-08)GABA neurones, as part of the GnRH network, play a significant role in the changes of age-related processes of the reproduction function. In order to study the regulation of the ovarian ... -
Molekulardynamische Untersuchungen zur Binnendynamik kollabierender Blasen
(2009-06-23)This work deals with the numerical simulation of cavitation- and sonoluminescence-bubbles, as well as laser-induced bubbles. The interior of the bubble is simulated by molecular ... -
Molekulare Analyse der differentiellen Funktionen von Linkerhiston Isoformen bei Caenorhabditis elegans.
(2002-01-29)Linker histones are non-essential for the life on single-celled eucaryotes. Linker histones, however, can be important components of specific developmental programs in multicellular animals ... -
Molekulare Analyse des Biotin-regulatorischen Netzwerks Sinorhizobium meliloti durch Proteomanalyse, Expressionsstudien und Mutagenesen
(2003-10-16)Sinorhizobium meliloti is not able to synthesize endogenous biotin. Biotin-limitation leads to a clear reduction of metabolic activities, whereas biotin-sufficiency has a positive ... -
Molekulare Mechanismen der Regulation der Glukagon-Gentranskription durch die Pax6-Homöodomäne
(2007-06-05)The peptide hormone glucagon increases glucose output from the liver and thus maintains sufficient blood glucose levels during the fasting state. Malfunctions in biosynthesis and secretion ... -
Molekulare Orientierung als Kontrastmechanismus in der Fluoreszenzmikroskopie und konfokale Multidetektor-Scanning-Mikroskopie
(2016-07-15)This doctoral thesis addresses two novel approaches in fluorescence microscopy. The first part introduces a new method that can be used to enhance the effect of photoselection. This method, termed ExPAN (excitation ... -
Molekulare und funktionelle Analyse des Gens rings lost (CG4420) in der Entwicklung von Drosophila melanogaster
(2010-05-17)Oogenesis of Drosophila is an attractive model system to study the arrangement of the actin-cytoskeleton. At the beginning of oogenesis a 16-cell cyst is formed and all cells of these cyst ... -
Molekulare und funktionelle Analyse von Windei (CG12340) als Bindungspartner der Histonmethyltransferase Eggless während der Oogenese von <i>Drosophila</i>
(2009-02-16)The epigenetic regulation of gene expression plays a very important role in development and is often mediated by the methylation of histones. Trimethylation of histone 3 lysine 9 (H3K9me3) ... -
Molekulare, biochemische und strukturelle Untersuchungen an amylolytischen Enzymen von Thermotoga maritima MSB8
(2001-08-01)One of the most thermophilic and ancient bacteria known to date, the hyperthermophilic Thermotoga maritima MSB8 (growth range: 55°C - 90°C), degrades and fermentatively utilizes organic ... -
Molekulargenetische Analysen fortpflanzungsrelevanter Fragestellungen beim landwirtschaftlichen Nutztier
(2018-12-04)This dissertation addresses two topics that are relevant for the reproduction of live-stock. The first part of the thesis describes genetic and environmental factors influenc-ing sperm quality in ejaculates of artificial ... -
Molekulargenetische und physiologische Untersuchungen zur Vererbung des Erbdefektes Hernia inguinalis/scrotalis beim Schwein
(2009-11-20)Hernia inguinalis/scrotalis (i/s) in pigs are known as congenital defects which occur with a frequency of 1-3% and a heritability of h2 = 0.02 to h2 = 0.86 in German pig breeds and ... -
Molekulargenetische und proteinanalytische Untersuchungen trächtigkeitsassoziierter Glykoproteine beim Rind
(2022-10-11)The dissertation addresses molecular genetic and protein analytical studies of bo-vine pregnancy-associated glycoproteins (boPAGs) and their practical application as pregnancy markers. Bovine PAGs are expressed by trophoblast ... -
