We present an implementation of a general weight window generator for global variance reduction in Geant4 based applications. The implementation is flexible and can be easily adjusted to a user-defined model. In this work, the weight-window generator was applied to calculations based on an instrument shielding model of the European Spallation Source, which is currently under construction in Lund,
Popular Abstract in Swedish Pankreascancer (cancer i bukspottkörteln) drabbar ungefär 900 personer om året i Sverige. Tumörformen har tidigare varit vanligare hos män men är numera lika vanlig hos män och kvinnor. Pankreascancer är ovanligt före 40 års ålder, men ökar stadigt med åldern och ungefär 80% av dem som drabbas är över 60 år gamla. Pankreascancer är en aggressiv tumörform och på grund av
Abstract in UndeterminedThe Palaeoproterozoic crust and upper mantle in the region between the Ukrainian and Baltic shields of the East European Craton were built up finally during collision of the previously independent Fennoscandian and Sarmatian crustal segments at c. 1.8-1.7 Ga. EUROBRIDGE seismic profiling and geophysical modelling across the southwestern part of the Craton suggest that the C
Objective: To investigate glycaemic and satiating properties of potato products in healthy subjects using energy-equivalent or carbohydrate-equivalent test meals, respectively. Subjects and setting: Thirteen healthy subjects volunteered for the first study, and 14 for the second. The tests were performed at Applied Nutrition and Food Chemistry, Lund University, Sweden. Experimental design and te
Inorganic phosphate is an essential molecule for all known life. Organisms have developed many mechanisms to ensure an adequate supply, even in low-phosphate conditions. In prokaryotes phosphate transport is instigated by the phosphate-binding protein (PBP), the initial receptor for the ATP-binding cassette (ABC) phosphate transporter. In the crystal structure of the PBP-phosphate complex, the pho
AIM: To investigate if and how the proinflammatory cytokine interferon gamma (IFN gamma) affects ghrelin expression in mice. METHODS: The plasma concentration of ghrelin, and gastric ghrelin and somatostatin expression, were examined in wild-type mice and mice infected with Helicobacter pylori (H. pylon). Furthermore, ghrelin expression was examined in two achlorhydric mouse models with varying de
Early-onset dominantly inherited forms of Alzheimer's disease (AD) are rare, but studies of such cases have revealed important information about the disease mechanisms. Importantly, mutations in amyloid precursor protein (APP), presenilin 1 (PSEN1) and PSEN2, alter the APP processing and lead to an increased amyloid beta-peptide (A beta) 42/40 ratio. This, together with other studies on pathogenic
A series of natural and synthetic piperine amides were evaluated for activity on the human TRPV1 expressed in HEK293 cells. The agonistic effect of piperine amides was mainly dependent on the length of the carbon chain. Structural changes of double bonds and stereochemistry in the aliphatic chain of these compounds did not change their potency or efficacy, indicating that increased rigidity or pla
We have studied the growth of doped InAsyP1-y (InAsP) NWs and InAsP-InP core-shell NWs. Using hydrogen chloride (HCl) we were able to prevent radial growth on the InAsP NWs. Undoped and H2S-doped InAsP NWs had almost pure wurtzite crystal structure, while DEZn-doped NWs showed wurtzite periodically separated by short sections of pure zincblende with rotational twins. Electrical measurements confir
In this letter we show that the use of slightly broadband laser sources like multimode alexandrite lasers for CH PLIF bears the danger of interferences from formaldehyde. Such interferences occur when the laser frequency is not carefully tuned to the B-X (0,0) R-branch band head at around 387.2 nm and manifest either in the appearance of an additional layer in the PLIF image or in a slight broaden
Popular Abstract in Swedish Centrala venkatetrar (CVK) används främst inom intensivvården men även allt mer inom annan vård på och utanför våra sjukhus. Oftast används CVK för tillförsel av mediciner och närings-lösningar, men även för mätning av blodomloppet och för bloddialys vid njursvikt. En CVK är en decimeterlång, smal plastslang, som med hjälp av en nål och en tunn metalledare förs in mot hCentral venous catheters are mainly being used for reliable infusion of fluids and potentially irritant drugs, for haemodialysis, and for assessment of right atrial or central venous pressure (RAP/CVP). Current guidelines state that central venous catheterization should be followed-up by immediate anterior-posterior chest X-ray to confirm appropriate positioning and to detect iatrogenic pneumothor
Background: Cancer in the sinonasal tract is rare, but persons who have been occupationally exposed to wood dust have a substantially increased risk. It has been estimated that approximately 3.6 million workers are exposed to inhalable wood dust in EU. In previous small studies of this cancer, ras mutations were suggested to be related to wood dust exposure, but these studies were too limited to d
Background: The n-3 polyunsaturated fatty acids eicosapentaenoic acid and docosahexaenoic acid, which are present in fish, are protective against myocardial infarction. However, fish also contains methylmercury, which influences the risk of myocardial infarction, possibly by generating oxidative stress. Methylmercury is metabolized by conjugation to glutathione, which facilitates elimination. Glut
AIM: We assessed prevalence and location of pain in a total population of children and adolescents with cerebral palsy (CP) based on the Gross Motor Function Classification System (GMFCS), age and gender. METHODS: This cross-sectional study was based on the last assessment of children aged 1-14 years in the combined Swedish follow-up programme and national quality register programme for CP. All
Popular Abstract in Swedish Omkring 16% av alla cancerfall i världen beräknas vara orsakade av infektioner och omkring 5% av dessa orsakas av humant papillomvirus (HPV). HPV har etablerats som orsak till livmoderhalscancer och kondylom (könsvårtor). HPV-typer som förekommer på hud har förknippats med icke-melanom hudcancer såsom skivepitelcancer (SCC) men också ofarliga hudhudförändringar som aktiAround 5% of all cancer cases worldwide are caused by human papillomavirus (HPV) which has been established as the cause of cervical cancer and genital warts (condylomas). Cutaneous HPV types have been weakly associated with non-melanoma skin lesions such as squamous cell carcinoma (SCC) and actinic keratosis (AK). We have analyzed skin and genital lesions for presence of HPV-DNA in order to searc
Objective. This study aimed to assess self-reported well-being in a clinical sample of stroke patients and to identify possible associations with prevalence, severity and bother of lower urinary tract symptoms (LUTS). Material and methods. A cross-sectional, clinical survey was initiated whereby stroke patients were invited to complete The WHO-Five Well-Being Index (WHO-5) and a LUTS instrument, t
Context: This review focuses on the prevention and management of complications following radical cystectomy (RC) for bladder cancer (BCa). Objective: We review the current literature and perform an analysis of the frequency, treatment, and prevention of complications related to RC for BCa. Evidence acquisition: A Medline search was conducted to identify original articles, reviews, and editorials a
Background and purpose Spasticity and muscle contracture are two common manifestations of cerebral palsy (CP). A spastic muscle may inhibit growth in length of the muscle, but the importance of this relationship is not known. In 1994, a register and a healthcare program for children with CP in southern Sweden were initiated. The child's muscle tone according to the Ashworth scale and the ankle ran
BACKGROUND: Gonadotropin-releasing hormone (GnRH) antagonists have been reported to have beneficial effects on lower urinary tract symptoms in patients with benign prostatic hyperplasia. OBJECTIVE: Our aim was to investigate the effects of ganirelix, a GnRH receptor antagonist, on bladder function and detrusor overactivity (DO) in female rats. DESIGN, SETTING, AND PARTICIPANTS: Female Sprague-Dawl
