Die Wahrnehmung der ostmitteleuropäischen Landreformen in Westeuropa 1918–1939
No full textNearly all East Central European states provided land reforms in the interwar period and changed the ethno-demographic and social composition of their populations by forced expropriation and redistribution of agrarian land. This and the impact on state economy and the system of property to land led to a broad interest of the decision making elites in Western Europe. The author presents several cases of diplomatic interferences by Great Powers which led to special exceptions in the legal implementation of the reforms. The article also focuses on the political background of academic and newspaper publications in English, French, and German on this topic. Nearly all scholars presented partial views which were motivated by national or social perspectives on the reform process. They mainly referred to civilization and progress as points of reference. Therefore contemporary scholars should take more care when they underline their arguments with contemporary literature.Nearly all East Central European states provided land reforms in the interwar period and changed the ethno-demographic and social composition of their populations by forced expropriation and redistribution of agrarian land.

Functional characterization of hepatic microsomal and heterologousely expressed rabbit cytochrome P450 2B enzymes
No full textThe objective of the research described in this dissertation was to characterize the function of four closely related cytochrome P450 2B enzymes in the rabbit. Although these enzymes display greater than 97% amino acid sequence identity, their expression is highly variable between different organs and in different individuals. Transient and stable heterologous expression systems were used to study the distinct catalytic properties of each P450 2B enzyme. Cytochrome P450 2B5 was found to have a unique pattern of catalytic activities in comparison to the P450 2B4, 2B-B1, and 2B-Bx forms. The regio- and stereoselectivity of hydroxylation of androstenedione in hepatic microsomes depended upon whether the animal expressed cytochrome P450 2B5. Whereas the catalytic activities of P450 2B5 were characterized by high steroid hydroxylase activities, P450 2B4 had relatively low steroid hydroxylase activity and much higher activity towards the non-steroid substrates than 2B5. Androstenedione 15α-hydroxylation and benzyloxyresorufin O-debenzylation were identified as selective markers of the activity of P450 2B5 and 2B4, respectively. Phencyclidine selectively inactivated P450 2B4 in hepatic microsomes from phenobarbital-induced rabbits as well as the expressed enzyme. The basis for poor inactivation of P450 2B5 by PCP was determined to be the low maximal rate constant for this P450 2B form. N-Aralkylated 1-aminobenzotriazole derivatives were found to be potent inactivators of both P450 2B enzymes and to be much less selective than phencyclidine. These results demonstrate that one or more of the amino acid differences in P450 2B5 are critical to its substrate specificities and selective inactivation. Rabbits which express P450 2B5 have the potential to exhibit different hepatic biotransformation pathways in comparison with animals that lack this enzyme.This item was digitized from a paper original and/or a microfilm copy.

Augustine's Disciplines: <i>Silent diutius Musae Varronis</i>?
No full textAbstract
Siding with Ritschl and Dyroff against Hadot, this chapter examines the hypothesis of a Varronian model for the ‘medieval’ scheme of the liberal arts, and provides new reasons for regarding Augustine as a crucial witness to this line of descent. It also examines the reasons why Augustine gave up on the liberal arts. The restoration of Varro's lost Musaemakes it easier to appreciate the difficulties Augustine faced in attempting to adapt these traditional figures of disciplinary thought to Christian purposes. The chapter suggests that the newly assembled evidence of the survival of Varronian themes and motifs in Late Antiquity makes it harder to suppose that any single author of that period, even one with the powers of Martianus Capella, could ever have restructured the tradition decisively.</jats:p
