In birds, fat accumulation before and during migration has been shown to be endogenously controlled and tuned by, among other factors, the Earth's magnetic field. However, our knowledge about the influence of the geomagnetic field on the fuelling in migrating birds is still limited to just a few nocturnally migrating passerine species. In order to study if variations of the magnetic field can also

The move towards fire performance-based design in building and transport regulations has led to an increased use of fire models. This increased use of these models and the evolution of different regulations have put higher demands on the predictive capability of fire models. The purpose of this paper is to give an overview of different activities relating to the validation and verification of comp

Abstract in UndeterminedOver the last decade a great deal of research attention has been paid to the Internet as a potential vehicle for civic and/or political engagement among young people. Many of these analyses have been looking (or perhaps hoping) for a simple cause-and-effect relationship. Young people seem uninterested in traditional forms of politics, but they are very interested in Interne

Inom ramen för det svenska forskningsprojektet Taktik och metodik vid brand i undermarksanläggningar har ett enkelt planeringsverktyg utvecklats som bl a erbjuder stöd till beslutsfattare involverade i planeringen av räddningsinsatser i väg- och järnvägstunnlar. Verktyget, som har utvecklats vid Lunds universitet, heter TuFT och är en förkortning av Tunnel Fire Tools. TuFT kan beskrivas som ett my

Objective The interleukin 2 (IL-2) and interleukin 21 (IL-21) locus at chromosome 4q27 has been associated with several autoimmune diseases, and both genes are related to immune system functions. The aim of this study was to evaluate the role of the IL-2/IL-21 locus in systemic sclerosis (SSc). Patients and methods The case control study included 4493 SSc Caucasian patients and 5856 healthy contro

Type-2 diabetes (T2D) is a complex disease characterized by insulin resistance in target tissues and impaired insulin release from pancreatic beta cells. As central tissue of glucose homeostasis, the pancreatic islet continues to be an important focus of research to understand the pathophysiology of the disease. The increased access to human pancreatic islets has resulted in improved knowledge of

Athletes constantly report experiences of momentum during athletic contests, and they consider momentum as being an important factor for the outcome of a competition. However, researchers trying to capture momentum with quantitative methods see themselves confronted with inconclusive results. To explain this gap between athletes’ belief and results from quantitative data, it is hypothesised that m

In this study, the relation between fruit and vegetable consumption and mortality was investigated within the European Prospective Investigation Into Cancer and Nutrition. Survival analyses were performed, including 451,151 participants from 10 European countries, recruited between 1992 and 2000 and followed until 2010. Hazard ratios, rate advancement periods, and preventable proportions to respec

The variables measured in modern pulse oximetry apparatuses include a graphical pulse curve and a specified perfusion value (PV) that could be a sensitive marker for detecting differences in sympathetic activity. We hypothesized that there is a correlation between a reduction of PV and the time to eye opening after general anaesthesia. The objective was to investigate whether PV can predict eye op

OBJECTIVE: The aim of this research was to study the discomfort experienced by adolescents when answering questions in a survey about sexuality and sexual abuse and to investigate factors that may determine possible experience of discomfort. The research focused particularly on vulnerable adolescents-sexually abused and sexually inexperienced. METHOD: Adolescents in their final year of high school

Streptococcus pyogenes of the M1 serotype can cause STSS, which is associated with significant morbidity and mortality. The purpose of the present study was to examine the role of NFAT signaling in M1 protein-induced lung injury. NFAT-luc mice were treated with the NFAT inhibitor A-285222 before administration of the M1 protein. Neutrophil infiltration, edema, and CXC chemokines were quantified in

Recoverin a member of the neuronal calcium sensor (NCS) branch of the calmodulin superfamily, is expressed in retinal photoreceptor cells and serves as a calcium sensor in vision. Ca2+-induced conformational changes in recoverin cause extrusion of its covalently attached myristate (termed Ca2+-myristoyl switch) that promotes translocation of recoverin to disk membranes during phototransduction in

MafA is a key transcriptional activator of islet beta cells and its exclusive expression within beta cells of the developing and adult pancreas is distinct amongst pancreatic regulators. Region 3 (base pairs -8118/-7750 relative to the transcription start site), one of six conserved 5' cis-domains of the MafA promoter, is capable of directing beta-cell-line-selective expression. Transgenic reporte

In this paper we investigate the size, structure and scaling relationships in glycogen isolated from five different animal sources. For this purpose a versatile fractionation technique, asymmetrical flow field-flow fractionation (AsFlFFF), coupled to multi-angle light scattering, is utilized. For determination of the average degree of branching 1H NMR is utilized. The results give a detailed insig

Abstract Conclusion: No statistically significant 5-year survival difference was seen in patients with oral and oropharyngeal squamous cell carcinoma (OOPSCC) between high-risk HPV-positive and -negative groups in this population-based study. Objectives: To see if the formerly observed higher risk for recurrence or second primary tumour (SPT) in high-risk HPV-positive patients with OOPSCC correspo

Low-frequency coding DNA sequence variants in the proprotein convertase subtilisin/kexin type 9 gene (PCSK9) lower plasma low-density lipoprotein cholesterol (LDL-C), protect against risk of coronary heart disease (CHD), and have prompted the development of a new class of therapeutics. It is uncertain whether the PCSK9 example represents a paradigm or an isolated exception. We used the "Exome Arra
