In the Western world, testicular germ cell cancer (TGCC) is the most common malignancy of young men. The malignant transformation of germ cells is thought to be caused by developmental and hormonal disturbances, probably related to environmental and lifestyle factors because of rapidly increasing incidence of TGCC in some countries. Additionally, there is a strong genetic component that affects su

Background: The effects of acetic acid, a common food preservative, on the bacteriophage-encoded enterotoxin A (SEA) expression and production in Staphylococcus aureus was investigated in pH-controlled batch cultures carried out at pH 7.0, 6.5, 6.0, 5.5, 5.0, and 4.5. Also, genomic analysis of S. aureus strains carrying sea was performed to map differences within the gene and in the temperate phag

Consider receivers that do not exploit any knowledge of the channel distribution in non-coherent block-fading multiple-input multiple-output (MIMO) channels. The main contribution of this letter is to derive a semi-analytical semi-numerical lower bound to the achieveble rate of such receivers. The bound is of operational meaning since practical receivers can achieve the lower bound. Several numeri

We have studied the nocturnal flight behaviour of the common swift (Apus apus L.), by the use of a tracking radar. Birds were tracked from Lund University in southern Sweden during spring migration, summer roosting flights and autumn migration. Flight speeds were compared with predictions from flight mechanical and optimal migration theories. During spring, flight speeds were predicted to be highe

Purposes To assess predictors of presenteeism (reduced productivity at work) and activity impairment outside work in patients with spondyloarthritis (SpA). Methods Multivariate logistic regression analysis was used to study predictors of presenteeism and activity impairment in 1,253 patients with SpA based on a 2.5 year follow-up questionnaire. The Work Productivity and Activity Impairment (WPAI)

Introduction: Haemophilia A (HA) and B (HB) are two of our most common inherited bleeding disorders and are due to a variety of gene mutations. Aims: The overall objective of the present research was to perform clinical and basic scientific studies on haemophilia in Sweden to further improve and individualise the care of haemophilia patients and their relatives. More specific aims were: to study t

Objective. Iron deficiency and anemia are being increasingly recognized as a complication of inflammatory bowel disease (IBD). The aim of this study was to observe, in a non-interventional way, how Swedish gastroenterologists adhere to guidelines in IBD outpatients treated with intravenous ferric carboxymaltose (FCM), and the result of treatment. Material and methods. Altogether 394 IBD patients (

Aims Inflammatory markers are established risk factors for atrial fibrillation (AF), but the role of autoimmune diseases is unknown. The aim of the study was to examine the association between coeliac disease (CD) and AF in a large cohort of patients with biopsy-verified CD. Methods and results We identified 28 637 patients with CD through biopsy reports (defined as Marsh 3: villous atrophy) from

Objectives: To describe the intake of vitamins thiamine (B1), riboflavin (B2), B6 (pyridoxine), B12 (cobalamine) and C (ascorbic acid) and their food sources among 27 centres in 10 countries participating in the European Prospective Investigation into Cancer and Nutrition (EPIC) study. Methods: Between 1995 and 2000, 36 034 persons aged between 35 and 74 years were administered a standardized 24-h

Föreliggande avhandling argumenterar för värdet av ett långsiktigt planetärt perspektiv i politiken. Vi har blivit vana att tänka på de risker som moderniteten genererar utifrån ett vidgat tidsligt och rumsligt perspektiv (till exempel utgör år 2100 en återkommande referenspunkt för forskningen kring globala klimatförändringar). På samma sätt bör vi fråga oss vilka politiska möjligheter som mänsklThis thesis propounds a techno-environmentalist position. Seeking to combine the need for natural restoration with human development, the thesis explores to what extent more radical forms of ecological modernization can offer a basis for political compromise and open new paths to global long-term sustainability. Based on three published articles, the thesis engages with existing literature on (a)

In this study linear free energy relationships (LFER) are applied to the relaxation of core-excited states in aliphatic CH3X compounds. There are at least two valence orbitals involved in Auger decay following C-CH3 1s -> sigma*(C-X) excitation, which may as well be localized on the substituents in this series. Therefore, the observed property cannot be strictly attached to the so-called reaction

The ability to reliably quantify activity in nuclear medicine has a number of increasingly important applications. Dosimetry for targeted therapy treatment planning or for approval of new imaging agents requires accurate estimation of the activity in organs, tumors, or voxels at several imaging time points. Another important application is the use of quantitative metrics derived from images, such

Behovet av modeller för att förutsäga risken för att ett företag inte skall kunna fullfölja sin skuldtjänst har aktualiserats av de nya Baselreglerna, som kräver fördjupad kvantitativ kreditvärdering, och av den pågående världsomspännande ekonomiska krisen. Ett antal alternativa modeller för att förutsäga kommande kreditsvårigheter och en eventuell konkurs existerar. Flera inkluderar makroekonomis

Huntington’s disease (HD) is a fatal, hereditary disorder caused by a mutation in the gene encoding the protein huntingtin. Although mutant huntingtin is ubiquitously expressed throughout the body, HD research has mainly focused on the role of the basal ganglia. Dysfunction of these brain nuclei likely underlies motor disturbances in HD, including the conspicuous, uncontrollable, dance-like moveme

The 2009 Kidney Disease: Improving Global Outcomes (KDIGO) clinical practice guideline on the monitoring, management, and treatment of kidney transplant recipients is intended to assist the practitioner caring for adults and children after kidney transplantation. The guideline development process followed an evidence-based approach, and management recommendations are based on systematic reviews of

Mantle cell lymphoma (MCL) is a distinct subtype of malignant lymphoma which is characterized by the chromosomal translocation t(11;14)(q13;q32) resulting in constitutional overexpression of cyclin D1 and cell cycle dysregulation in almost all cases. Clinically, MCL shows an aggressive clinical course with a continuous relapse pattern and a median survival of only 3-5 years. However, recently a su
