Bokkapitel (refereegranskat)abstract
- This introductory chapter provides an overview of the history of Satanism. As an open identity, Satanism only became possible in a time when Christianity’s hold on legal systems and social norms weakened. In that sense, Satanism is a direct product of secularization. As a religious practice or coherent system of thought, Satanism did not exist any earlier than around the year 1900, when pioneers like Stanislaw Przybyszewski and Ben Kadosh appeared. However, strands of Satanic thought can be found in a series of instances prior to this, and some of these early ideas remain influential today. The chapter also looks at the establishment of groups like the Church of Satan, the Process Church of the Final Judgement, the Temple of Set, and the Order of the Nine Angles. While never a numerically significant religion, Satanism’s controversial and confrontational character makes it an excellent case study for discussing broader methodological and theoretical issues.

- AIM: This paper describes the quality assurance (QA) work performed in the Swedish multicenter ARTSCAN (Accelerated RadioTherapy of Squamous cell CArcinomas in the head and Neck) trial to guarantee high quality in a multicenter study which involved modern radiotherapy such as 3DCRT or IMRT. MATERIALS AND METHODS: The study was closed in June 2006 with 750 randomised patients. Radiation therapy-related data for every patient were sent by each participating centre to the QA office where all trial data were reviewed, analysed and stored. In case of any deviation from the protocol, an interactive process was started between the QA office and the local responsible clinician and/or physicist to increase the compliance to the protocol for future randomised patients. Meetings and workshops were held on a regular basis for discussions on various trial-related issues and for the QA office to report on updated results. RESULTS AND DISCUSSION: This review covers the 734 patients out of a total of 750 who had entered the study. Deviations early in the study were corrected so that the overall compliance to the protocol was very high. There were only negligible variations in doses and dose distributions to target volumes for each specific site and stage. The quality of the treatments was high. Furthermore, an extensive database of treatment parameters was accumulated for future dose-volume vs. endpoint evaluations. CONCLUSIONS: This comprehensive QA programme increased the probability to draw firm conclusions from our study and may serve as a concept for QA work in future radiotherapy trials where comparatively small effects are searched for in a heterogeneous tumour population.

- We have determined the solution structure of an albumin binding domain of protein G, a surface protein of group C and G streptococci. We find that it folds into a left handed three-helix bundle similar to the albumin binding domain of protein PAB from Peptostreptococcus magnus. The two domains share 59% sequence identity, are thermally very stable, and bind to the same site on human serum albumin. The albumin binding site, the first determined for this structural motif known as the GA module, comprises residues spanning the first loop to the beginning of the third helix and includes the most conserved region of GA modules. The two GA modules have different affinities for albumin from different species, and their albumin binding patterns correspond directly to the host specificity of C/G streptococci and P. magnus, respectively. These studies of the evolution, structure, and binding properties of the GA module emphasize the power of bacterial adaptation and underline ecological and medical problems connected with the use of antibiotics.

- PurposeRadiation therapy (RT) after breast-conserving surgery reduces locoregional recurrences and improves survival but may cause late side effects. The main purpose of this paper was to investigate long-term side effects after whole breast RT in a randomized clinical trial initiated in 1991 and to report dose-volume data based on individual 3-dimensional treatment plans for organs at risk.Methods and MaterialsThe trial included 1187 patients with T1-2 N0 breast cancer randomized to postoperative tangential whole breast RT or no further treatment. The prescription dose to the clinical target volume was 48 to 54 Gy. We present 20-year follow-up on survival, cause of death, morbidity, and later malignancies. For a cohort of patients (n = 157) with accessible computed tomography–based 3-dimensional treatment plans in Dicom-RT format, dose-volume descriptors for organs at risk were derived. In addition, these were compared with dose-volume data for a cohort of patients treated with contemporary RT techniques.ResultsThe cumulative incidence of cardiac mortality was 12.4% in the control group and 13.0% in the RT group (P = .8). There was an increase in stroke mortality: 3.4% in the control group versus 6.7% in the RT group (P = .018). Incidences of contralateral breast cancer and lung cancer were similar between groups. The median Dmean (range) heart dose for left-sided treatments was 3.0 Gy (1.1-8.1), and the corresponding value for patients treated in 2017 was 1.5 Gy (0.4-6.0).ConclusionsIn this trial, serious late side effects of whole breast RT were limited and less than previously reported in large meta-analyses. We observed no increase in cardiac mortality in irradiated patients. Doses to the heart were a median Dmean of 3.0 Gy for left-sided RT. The observed increase in stroke mortality may partly be secondary to cardiac side effects, complications to anticoagulant treatment, or to chance, rather than a direct side effect of tangential whole breast irradiation.

- Background and purpose. The variability in target delineation for similar cases between centres treating paediatric and adolescent patients, and the apparent differences in interpretation of radiotherapy guidelines in the treatment protocols encouraged us to perform a dummy-run study as a part of our quality assurance work. The aim was to identify and quantify differences in the segmentation of target volumes and organs at risk (OARs) and to analyse the treatment plans and dose distributions. Materials and methods. Four patient cases were selected: Wilms tumour, Hodgkins disease, rhabdomyosarcoma of the prostate and chordoma of the skull base. The five participating centres received the same patient-related material. They introduced the cases in their treatment planning system, delineated target volumes and OARs and created treatment plans. Dose-volume histograms were retrieved for relevant structures and volumes and dose metrics were derived and compared, e. g. target volumes and their concordance, dose homogeneity index (HI), treated and irradiated volumes, remaining volume at risk and relevant V x and D x values. Results. We found significant differences in target segmentation in the majority of the cases. The planning target volumes (PTVs) varied two-to four-fold and conformity indices were in the range of 0.3-0.6. This resulted in large variations in dose distributions to OARs as well as in treated and irradiated volumes even though the treatment plans showed good conformity to the PTVs. Potential reasons for the differences in target delineation were analysed. Conclusion. Considerations of the growing child and difficulties in interpretation of the radiotherapy information in the treatment protocols were identified as reasons for the variation. As a result, clarified translated detailed radiotherapy guidelines for paediatric/adolescent patients have been recognised as a way to reduce this variation.

- In vitro studies suggest that the G protein-coupled receptor (GPR) 30 is a functional estrogen receptor. However, the physiological role of GPR30 in vivo is unknown, and it remains to be determined whether GPR30 is an estrogen receptor also in vivo. To this end, we studied the effects of disrupting the GPR30 gene in female and male mice. Female GPR30((-/-)) mice had hyperglycemia and impaired glucose tolerance, reduced body growth, increased blood pressure, and reduced serum IGF-I levels. The reduced growth correlated with a proportional decrease in skeletal development. The elevated blood pressure was associated with an increased vascular resistance manifested as an increased media to lumen ratio of the resistance arteries. The hyperglycemia and impaired glucose tolerance in vivo were associated with decreased insulin expression and release in vivo and in vitro in isolated pancreatic islets. GPR30 is expressed in islets, and GPR30 deletion abolished estradiol-stimulated insulin release both in vivo in ovariectomized adult mice and in vitro in isolated islets. Our findings show that GPR30 is important for several metabolic functions in female mice, including estradiol-stimulated insulin release.

- In this paper is described the preparation of patterned cell dishes to be used in studies of low dose irradiation effects on living cells. Using a droplet microdispenser, an 8 mu m thick polypropylene cell substrate, to which cells do not naturally adhere, was coated in a matrix pattern with the cell adhesive mussel protein Cell-Tak. Cells were shown to adhere and grow on the protein-coated spots, but not on the uncoated parts, providing for guided cell growth. Cultivation of isolated cell colonies provides an opportunity to study how low doses of ionizing radiation affect neighbouring un-irradiated cell colonies. (C) 2009 Elsevier B.V. All rights reserved.
