Consumption and the lifestyle of the high nobility in eighteenth-century Sweden This monograph is an analysis of the lifestyle, consumption and private finances of the Swedish high nobility during the eighteenth century (ca 1730 1795). It describes the lifestyle of one noble house, the House of Fersen. The Fersen family represents the leading political, economic and cultural elite in eighteenth-century Sweden. The analysis concentrates on Count Carl von Fersen (1716 1786) and his brother Count Axel von Fersen (1719 1794), their spouses and children. Carl von Fersen was a courtier whilst Axel von Fersen was an officer and one of the leaders of the Francophile Hat party. His son, Axel von Fersen the younger, was in his time an officer and a favourite of Gustavus III, King of Sweden, as well as a favourite and trusted confidant of Marie-Antoinette, Queen of France. The research is based upon the Fersen family s private archives, the Counts personal account books, probate inventories, letters and diaries. The study discusses the Fersens landed property and investments in ironworks and manufacturing, the indebtedness of the high nobility, high offices in civil administration, the militia and at court, as well as marriages as the foundations of noble wealth and power. It analyses the Count von Fersens revenue and expenditure, their career options and personal expenses, their involvement in the building and decorating of palaces, and the servants in service of the Fersen family as well as the ideal nobleman and his consumption. Central themes are inheritance, children s education, marriages and ladies preparing their trousseaux, the nobility ordering luxury goods from France, the consumption of Counts and Countesses before and after marrying and having children, the pleasures of a noble life as well as the criticism of luxury and sumptuousness. The study contributes to the large body of research on consumption and nobility in the eighteenth century by connecting the lifestyle, consumption and private finances of the Swedish high nobility to their European context. Key words: nobility, Fersen, lifestyle, consumption, private finances, Sweden, eighteenth century

Oncolytic Adenoviruses for Gynecologic Cancer

Gene therapy is a promising novel approach for treating cancers resistant to or escaping currently available modalities. Treatment approaches are based on taking advantage of molecular differences between normal and tumor cells. Various strategies are currently in clinical development with adenoviruses as the most popular vehicle. Recent developments include improving targeting strategies for gene delivery to tumor cells with tumor specific promoters or infectivity enhancement. A rapidly developing field is as well replication competent agents, which allow improved tumor penetration and local amplification of the anti-tumor effect. Adenoviral cancer gene therapy approaches lack cross-resistance with other treatment options and therefore synergistic effects are possible. This study focused on development of adenoviral vectors suitable for treatment of various gynecologic cancer types, describing the development of the field from non-replicating adenoviral vectors to multiple-modified conditional replicating viruses. Transcriptional targeting of gynecologic cancer cells by the use of the promoter of vascular endothelial growth factor receptor type 1 (flt-1) was evaluated. Flt-1 is not expressed in the liver and thus an ideal promoter for transcriptional targeting of adenoviruses. Our studies implied that the flt-1 promoter is active in teratocarcinomas.and therefore a good candidate for development of oncolytic adenoviruses for treatment of this often problematic disease with then poor outcome. A tropism modified conditionally replicating adenovirus (CRAd), Ad5-Δ24RGD, was studied in gynecologic cancers. Ad5-Δ24RGD is an adenovirus selectively replication competent in cells defective in the p16/Rb pathway, including many or most tumor cells. The fiber of Ad5-Δ24RGD contains an integrin binding arginine-glycine-aspartic acid motif (RGD-4C), allowing coxackie-adenovirus receptor independent infection of cancer cells. This approach is attractive because expression levels of CAR are highly variable and often low on primary gynecological cancer cells. Oncolysis could be shown for a wide variety of ovarian and cervical cancer cell lines as well as primary ovarian cancer cell spheroids, a novel system developed for in vitro analysis of CRAds on primary tumor substrates. Biodistribution was evaluated and preclinical safety data was obtained by demonstrating lack of replication in human peripheral blood mononuclear cells. The efficicacy of Ad5-Δ24RGD was shown in different orthotopic murine models including a highly aggressive intraperitoneal model of disseminated ovarian cancer cells, where Ad5-Δ24RGD resulted in complete eradication of intraperitoneal disease in half of the mice. To further improve the selectivity and specificity of CRAds, triple-targeted oncolytic adenoviruses were cloned, featuring the cyclo-oxygenase-2 (cox-2) promoter, E1A transcomplementation and serotype chimerism. Those viruses were evaluated on ovarian cancer cells for specificity and oncolytic potency with regard to two different cox2 versions and three different variants of E1A (wild type, delta24 and delta2delta24). Ad5/3cox2Ld24 emerged as the best combination due to enhanced selectivity without potency lost in vitro or in an aggressive intraperitoneal orthotopic ovarian tumor model. In summary, the preclinical therapeutic efficacy of the CRAds tested in this study, taken together with promising biodistribution and safety data, suggest that these CRAds are interesting candidates for translation into clinical trials for gynecologic cancer.

Lantibiotic Nisin and Its Detection Methods

The type A lantibiotic nisin produced by several Lactococcus lactis strains, and one Streptococcus uberis strainis a small antimicrobial peptide that inhibits the growth of a wide range of gram-positive bacteria, such as Bacillus, Clostridium, Listeria and Staphylococcus species. It is nontoxic to humans and used as a food preservative (E234) in more than 50 countries including the EU, the USA, and China. National legislations concerning maximum addition levels of nisin in different foods vary greatly. Therefore, there is a demand for non-laborious and sensitive methods to identify and quantify nisin reliably from different food matrices. The horizontal inhibition assay, based on the inhibitory effect of nisin to Micrococcus luteus is the base for most quantification methods developed so far. However, the sensitivity and accuracy of the agar diffusion method is affected by several parameters. Immunological tests have also been described. Taken into account the sensitivity of immunological methods to interfering substances within sample matrices, and possible cross-reactivities with lantibiotics structurally close to nisin, their usefulness for nisin detection from food samples remains limited. The proteins responsible for nisin biosynthesis, and producer self-immunity are encoded by genes arranged into two inducible operons, nisA/Z/QBTCIPRK and nisFEG, which also contain internal, constitutive promoters PnisI and PnisR. The transmembrane histidine kinase NisK and the response regulator NisR form a two-component signal transduction system, in which NisK autophosphorylates after exposure to extra cellular nisin, and subsequently transfers the phosphate to NisR. The phosphorylated NisR then relays the signal downstream by binding to two regulated promoters in the nisin gene cluster, i.e the nisA/Z/Qand the nisF promoters, thus activating transcription of the structural gene nisA/Z/Q and the downstream genes nisBTCIPRK from the nisA/Z/Q promoter, and the genes nisFEG from the nisF promoter. In this work two novel and highly sensitive nisin bioassays were developed. Both of these quantification methods were based on NisRK mediated, nisin induced Green Fluorescent Protein (GFP) fluorescence. The suitabilities of these assays for quantifica¬tion of nisin from food samples were evaluated in several food matrices. These bioassays had nisin sensitivities in the nanogram or picogram levels. In addition, shelf life of nisin in cooked sausages and retainment of the induction activity of nisin in intestinal chyme (intestinal content) was assessed.

Valistus suomalaisessa kirjakulttuurissa 1700-luvulla

The dissertation discusses the history of the book and the Enlightenment in Finland by studying the reception and diffusion of eighteenth-century books and by approaching the discourse on the Enlightenment in Finnish source material. The methods used relate to historian Robert Darnton s studies on eighteenth-century print culture and his analyses of the relations between print culture and society. The study is based on diverse eighteenth-century sources: books, pamphlets and dissertations, bibliographies, book auction protocols, parliamentary documents, estate inventory deeds, newspapers, letters, lectures, memoirs and commonplace books. By the end of the eighteenth century, book production had increased and secular literature had begun to challenge the dominance of religious literature. The books of the Enlightenment belonged to the new literature that found its way into Finnish book collections previously dominated by religious literature. Enlightenment literature is not a set selection of books but rather diverse works from different genres. Thus the study introduces a variety of printed material, from philosophical tracts and textbooks to novels and pornography. In the case of books of the Enlightenment, the works of French Voltaire and German Christian Wolff were among the most widely read and circulated books in Finland. First and foremost, the Enlightenment was an era of intellectual debate. These debates carried strong criticism of the prevailing systems of thought. Enlightenment ideas challenged the Lutheran society of Sweden and especially its sense of conformity. Contemporaries saw many of the books of the Enlightenment as vessels of new ideas and criticism. Furthermore, this kind of print material was interpreted as being dangerous for uneducated readers. Belonging to a certain estate and social class had a major impact on individuals reading habits and their acquisition of books. One specific social group stands out in the Finnish source material: the officers at the Sveaborg naval fortress possessed and distributed Enlightenment books more than the members of any other social class. Other essential social groups were scholars, the nobility and the clergy, who took part in debates concerning the ideas and benefits of the Enlightenment. In the Finnish debates at the time, the concept of Enlightenment involved three primary notions. Firstly, it referred to the French philosophers, les philosophes, and to their works as well as to the social changes that took place during the French revolution. It also carried the idea of philosophical light or the light of reason, in a sense similar to Immanuel Kant s writings. Most importantly, it referred to a belief in progress and to a trust in true knowledge that would supercede ignorance and fanaticism. Hence, it is impossible to speak about the Enlightenment era in the Swedish realm without such concepts as reason, benefit or progress. These concepts likewise marked the books of the Enlightenment in eighteenth-century Finland.
