Die phylogenetische Position der Mollusken innerhalb der Trochozoa sowie die interne Evolution der Klassen der Mollusca sind weitgehend unbekannt und wurden in meiner Arbeit anhand molekularer Merkmale untersucht. Phylogenomische Analysen zeigten in der Vergangenheit eine gute Auflösung für ursprüngliche Speziationsereignisse. Daher wurden hier drei neue EST Datensätze generiert: für Sipunculus nudus (Sipuncula), Barentsia elongata (Kamptozoa) und Lepidochitona cinerea, (Polyplacophora, Mollusca). Zusätzlich wurden gezielt Gene verschiedener Mollusken mittels RT-PCR amplifiziert. rnSowohl Kamptozoen als auch Sipunculiden wurden aufgrund morphologischer Kriterien bisher als mögliche Schwestergruppe der Mollusken gehandelt, aber die hier erzielten Ergebnisse zur Evolution der Hämerythrine, Gen-Anordnungen der mitochondrialen Genome und phylogenetische Analysen der ribosomalen und der mitochondriellen Proteine stützen diese Hypothese nicht. Die Position der Kamptozoa erwies sich hier generell als unbeständig; phylogenomische Analysen deuten eine Nähe zu den Bryozoen an, aber diese Position wird stark durch die Auswahl der Taxa beeinflusst. Dagegen weisen meine Analysen klar auf eine nähere Beziehung zwischen Annelida und Sipuncula hin. Die ribosomalen Proteine zeigen Sipuncula (und Echiura) sogar als Subtaxa der Anneliden. Wie den Mollusken fehlt den Sipunculiden jegliche Segmentierung und meine Ergebnisse legen hier die Möglichkeit des Verlusts dieses Merkmals innerhalb der Anneliden bei den Sipunculiden nahe. Innerhalb der Mollusken wurden die Solenogastren bereits als Schwestergruppe aller rezenten Mollusken vorgeschlagen. Im Rahmen meiner Arbeit wurden von drei verschiedenen Solenogastren-Arten die ersten zuverlässigen 18S rRNA-Sequenzen ermittelt, und es zeigte sich, dass alle bisher veröffentlichten 18S-Sequenzen dieser Molluskenklasse höchst unvollständig oder fehlerhaft sind. rnRibosomale Proteine sind gute phylogenetische Marker und hier wurden die Auswahl und Anzahl dieser Gene für phylogenetische Analysen optimiert. Über Sonden-basierte Detektion wurde eine sampling-Strategie getestet, die im Vergleich mit standard-phylogenomischen Ansätzen zukünftige molekulare Stammbaumrekonstruktionen mit größerem Taxonsampling ermöglicht.rn

This dissertation has two main purposes. On the one hand, it aims at comparing the gender stereotypes presented in the television commercials in China and in Europe. Considering the cultural, historical and socio-economical differences between these two contexts, it is interesting to examine the gender role models offered and used by the advertising industry in European Union and China in order to see if the gender stereotypes are similar and to evaluate to which extent they reflect, challenge or reinforce the gender roles of the society where they are broadcasted. On the other hand, the objective of this dissertation is to establish the degree of adequateness and effectiveness of the existing regulatory framework through an analysis of the positive and negative aspects of the regulatory acts issued to safeguard a fair representation of genders in the EU Member States and in China.

OBJECTIVE: To analyze concentrations of endometrial leukocytes in patients with idiopathic-repeated abortions. MATERIALS AND METHODS: Biopsies of exactly dated secretory endometrium in 25 patients with idiopathic-repeated abortions and 10 control patients without a history of miscarriage were compared with respect to the concentrations of T-helper cells (CD4), cytotoxic T-cells (CD8), B-cells (CD19) and uterine natural killer cells (CD56) by immunohistochemistry and RNase protection assays. RESULTS: All examined cells were detectable within secretory endometrium. No statistically significant differences of the examined immune-cell concentrations were seen between the control group and the repeated miscarriage group by either test. CONCLUSION: This study suggests that the concentrations of specific endometrial leukocytes in a non-pregnant cycle are not associated with repeated pregnancy loss. Thus, the hypothesis of an altered endometrial immunity in patients with repeated miscarriages, symbolized by persistently differing local immune-cell concentrations, has to be questioned.

Adiponectin is an adipokine, present in the circulation in comparatively high concentrations and different molecular weight isoforms. For the first time, the distribution of these isoforms in serum and follicular fluid (FF) and their usefulness as biological markers for infertility investigations was studied.

The volume contains two analytical chapters, "Finding the Sacred" and "Language as Landscape"; a fair amount of autobiographical material describing Summers's research process; an Omaha Language Pronunciation Guide; selected historical material; and a mixture of photos, including of the author with other Omaha language students. There are a number of editorial malfunctions, including the analytical chapters' tendency to wander around various topics; moreover, the author's role as editor of the firsthand accounts is never made explicit.

There exists some discrepancy considering the overall health and well-being of young women in sports and performance domains. The current study aimed to examine self-reported levels of perfectionism, body esteem, and social support among college women participating in organized sports and dance. A total of 103 participants completeda series of questionnaires intended to capture these major variables of interest. Results upheld one of three major hypotheses, specifically in regards to between-group differences for lean and non-lean sport athletes. One of the most important findings wasthat among lean sport participants the relationship between body esteem and social support was statistically significant and positive, and among non-lean sport participants this same relationship was nonsignificant and negative. The applied implication of thisfinal finding is discussed, with particular emphasis on potential strategies for upholding the positive relationship between body esteem and social support among lean sport athletes.

The aim of this study was to evaluate serum and peritoneal fluid (PF) glycodelin-A concentrations in women with ovarian endometriosis. Ninety-nine matched pairs of serum and PF samples were included in our study. The case group comprised 57 women with ovarian endometriosis and the control group 42 healthy women undergoing sterilization or patients with benign ovarian cysts. Glycodelin-A concentrations were measured using ELISA. Endometriosis patients had significantly higher serum and PF glycodelin-A concentrations compared to controls, and this increase was observed in both proliferative and secretory cycle phases. Glycodelin-A concentrations were more than 10-fold higher in PF than in serum and correlated with each other. Intensity and frequency of menstrual pain positively correlated with glycodelin-A concentrations. Sensitivity and specificity of glycodelin-A as a biomarker for ovarian endometriosis were 82.1% and 78.4% in serum, and 79.7% and 77.5% in PF, respectively. These results indicate that Glycodelin-A has a potential role as a biomarker to be used in combination with other, independent marker molecules.

The study considered the discrepancy between the official status and real position of Russian provincial officialdom in the middle of the 19th century. The law was not entirely coherent in all aspects of the officials' life and activity, with ordinary deviations from the law being adopted in practice and accepted, albeit not openly, by the public and sometimes even by the authorities. The main law determining the rights and duties of governors was never followed to the letter and in reality governors' activities were determined by the common (unwritten) law existing in the governmental sphere. The volume and nature of the governors' rights depended on a range of factors, with specific regional features and the governor's personal qualities having a particular significance. The standard of living of government clerks was much higher than their official salary would permit and Matkhanova studied the most widespread cases of abuse, identifying those positions in the administration which offered the most opportunities for such abuses. At the start of the period and on the eve of the reforms public opinion towards the bribery of officials underwent a change. From the late 1850s onwards, there appeared among provincial officials a group of young well-educated clerks with liberal ideas and a new system of moral values which did not allow them to accept bribes or infringe the law in any way. There was also a non-official hierarchy side by side with the legally existing one. A significant role in governing the region, and one which has been underestimated by historians, was played by the head of the governor's office, but the reforms of the 1860s contributed to changing this state of affairs.
