Fourteen non-terrorist attackers of public figures in Germany between 1968 and 2004 were intensively studied, with a particular focus on warning behaviors, attack behaviors, and the relationship between psychiatric diagnosis, symptoms, and motivations for the assault. A large proportion of the attackers were severely mentally ill, and most likely to be in the potentially lethal rather than the non-lethal group. A new typology of seven warning behaviors was applied to the data, and all were present, most frequently fixation and pathway warning behavior, and least frequently a direct threat. Psychiatric diagnosis could be closely linked to motivation when analyzed at the level of symptom and content of thought, often delusional. Most of the attacks were directed at political figures, and the majority occurred after 1995.

The production of epithelial neutrophil activating peptide-78 (NA-78) and the interleukins IL-8 and IL-6 by endometrial stromal cells is stimulated by pro-inflammatory interleukin-1 (IL-1) and tumour necrosis factor-α (TNF-α). IL-8 is suggested to play a role in the pathogenesis of endometriosis, and in these women the peritoneal fluid concentrations of ENA-78 and IL-8 are increased. TNF-α has been tested together with interferon-γ because of their cooperative stimulation of IL-6. The release of IL-8, however, is inhibited with increasing interferon levels. The aim of the study was the analysis of the production of ENA-78, IL-6 and IL-8 by cultured human endometrial stromal cells in the presence of varying concentrations of IL-1β, TNF-α, and interferon-γ.

This project looked at the various responses, both political and aesthetic, to the end of socialist realism and the return of pre-war modernism as a desirable ideal. It considered both the built environment and objects of daily use (furniture, radios, TV sets, etc.) in several countries of the region, including Estonia, Hungary, Poland, Russia and Romania, also comparing developments there with corresponding ones in the west. Among particular aspects considered were the effects of Kruschev's speech in December 1954 to workers in construction, machine-building and design industries, in which he argued against monumentalism and criticised both "classical architecture" and socialist realism. The team see the real issue in interpreting Eastern European architecture as its lack of a critical edge, since official discourses took the place of any form of criticism and architects sought to implement the "official line". Megastructures became increasingly popular from the 1960s onwards and in Romania, for instance, came to dominate the city in the late 1980s. Such structures proved an efficient way to control the environment in countries plagued by prefabrication and social housing, and the group see the exhibition of inflated concrete grids as perhaps the most important feature of Eastern European architecture in the 1960s and 1970s. They also point out the rarity of glass and steel architecture in the east, where the preferred material was concrete, a material seen as "revolutionary" as it was the product of heavy industry and was grey, i.e. the workers' colour. Tactile elements were more important here than the visual elements favoured in the west, and a solidity more in line with the dominant ideology than the ephemeral qualities of glass.

BACKGROUND: It is known that endometriosis is an inflammatory disease and those patients seem to have lower pregnancy rates. The aim of the study was to investigate the concentrations of chemokines and proinflammatory cytokines in the follicular fluid of patients with and without endometriosis. METHODS: Follicular aspiration, recovering follicular fluid during assisted reproductive treatment, follicular fluid storage and analysis of chemokines and proinflammatory cytokines were carried out. Tumor necrosis factor-alpha, interleukin-1 beta, interleukin-6, interleukin-8, interleukin-15, leukemia inhibitory factor, epithelial neutrophil-activating peptide 78, regulated upon activation, normal T-cell expressed and secreted, and growth-regulated oncogene-alpha were analyzed in the follicular fluid and compared between women with (n =47) and without endometriosis (n = 279). RESULTS: The above cytokines were detected in the follicular fluid samples. Epithelial neutrophil-activating peptide 78 levels were significantly higher in follicular fluid from endometriosis patients than from controls (p = 0.008). Increases (to twice the control level) were also observed for tumor necrosis factor-alpha and for interleukin-6. CONCLUSIONS: Increased follicular fluid levels of epithelial neutrophil-activating peptide 78, tumor necrosis factor-alpha and interleukin-6 indicate that these cytokines may influence oocyte quality and fecundability of women with endometriosis by deteriorating the microenvironment in the human follicle.

In May of 1968, workers at the Kingston mine, a branch of the Calumet Division of Universal Oil Products walked off the site in protest of a safety issue involving a man-car. Knowing their contracts were due for negotiation in just a few months, the workers quickly returned, only to find themselves striking yet again just three months later, when negotiations failed. Requesting pay equal to that of the workers at the nearby White Pine mine was unacceptable to the heads of Universal Oil, the corporation which bought the long running Calumet & Hecla just a year earlier in 1968. The strike would last for nine months, ending in a total shutdown of all mining operations on the Keweenaw Peninsula, and bring an economic hardship to the area that would take decades to recover from. The Copper Strike of 1968-1969 is often forgotten, though extremely important to the story of the copper industry in Michigan, as well as to the United States. This paper has not yet been submitted.

Serine residues of the human insulin receptor (HIR) may be phosphorylated and negatively regulate the insulin signal. We studied the impact of 16 serine residues in HIR by mutation to alanine and co-overexpression in human embryonic kidney (HEK) 293 cells together with the docking proteins insulin receptor substrate (IRS)-1, IRS-2, or (SHC) Src homologous and collagen-like. As a control, IRS-1 was also cotransfected with an HIR with a juxtamembrane deletion (HIR delta JM) and therefore not containing the domain required for interaction with IRS-1. Coexpression of HIR with IRS-1, IRS-2, and SHC strongly enhanced tyrosine phosphorylation of these proteins. A similar increase in tyrosine phosphorylation was observed in cells overexpressing IRS-1, IRS-2, or SHC together with all HIR mutants except HIR delta JM and a mutant carrying exchanges of serines 1177, 1178, and 1182 to alanine (HIR1177/78/82), although this mutant showed normal autophosphorylation. Analysis of total cell lysates with anti-phosphotyrosine antibodies showed that in addition to the overexpressed substrates, other cellular proteins displayed reduced levels of tyrosine phosphorylation in these cells. To study consequences for phosphatidylinositol 3-kinase (PI 3-kinase) activation, we established stable NIH3T3 fibroblast cell lines overexpressing wild-type HIR, HIR1177/78/82, and other HIR mutants as the control. Again, HIR1177/78/82 showed normal autophosphorylation but showed a clear decrease in tyrosine phosphorylation of endogenous IRS-1 and activation of PI 3-kinase. This decrease in kinase activity also occurred in an in vitro kinase assay towards recombinant IRS-1. Finally, we performed a separation of the phosphopeptides by high-performance liquid chromatography and could not detect any differences in the profiles of HIR and HIR1177/78/82. In conclusion, we have defined a region in HIR that is important for substrate phosphorylation but not autophosphorylation. Therefore, this mutant may provide new insights into the mechanism of kinase activation and substrate phosphorylation.

The purpose of this thesis is to analyze the evolution of an early 20th century mining system in Spitsbergen as applied by Boston-based Arctic Coal Company (ACC). This analysis will address the following questions: Did the system evolve in a linear, technological-based fashion? Or was the progression more a product of interactions and negotiations with the natural and human landscapes present during the time of occupation? Answers to these questions will be sought through review of historical records and material residues identified during the 2008 field examination on Spitsbergen. The Arctic Coal Company’s flagship mine, ACC Mine No. 1, will serve as the focus for this analysis. The mine was the company’s largest undertaking during its occupation of Longyear Valley and today exhibits a large collection of related features and artifacts. The study will emphasize on the material record within an analysis of technical, environmental and social influences that guided the course of the mining system. The intent of this thesis is a better understanding of how a particular resource extraction industry took root in the Arctic.
