En av de vanligaste frågorna som brukar ställas till astronomer är om det finns liv någon annanstans i universum. Vi har ännu inget enkelt svar. Framsteg mot ett svar på denna fråga görs lite i taget. Den här avhandlingen är ett av dessa steg.Min forskning är inriktad på atmosfärerna hos så kallade "ultra-hot Jupiters": planeter i Jupiters storlek som kretsar så nära sina stjärnor att de hettas upOne of the biggest questions people ask astronomers is whether life exists elsewhere in the universe. Unfortunately, we don’t yet have an answer. Instead, progress towards an answer comes in small, careful steps. This thesis is one of those steps.My research has focused on the atmospheres of "ultra-hot Jupiters": planets the size of Jupiter that orbit so close to their stars they are heated to tho

Every smoker should be offered smoking cessation treatment when they present for clinical care. The Readiness to Change-Smokers (RTC-S) questionnaire and the Heidelberg Smoking History (HSH) are brief questionnaires that divide patients into three stages. The purpose of this study was to prospectively compare the performance of each questionnaire at identifying patients who will successfully quit

Translation of novel discoveries to human disease is limited by the availability of human tissue-based models of disease. Precision-cut lung slices (PCLS) used as 3D lung tissue cultures (3D-LTCs) represent an elegant and biologically highly relevant 3D cell culture model, which highly resemble in situ tissue due to their complexity, biomechanics and molecular composition. Tissue slicing is widely

Det antika Athen hade sin första blomstringstid under 400- och 300-talen f.Kr. Det hade då en ledande ställning i den grekiska världen, och från den tiden härstammar mycket av det som väckt senare tiders beundran – klassisk skulptur, arkitektoniska mästerverk som Parthenon, dramerna som fortfarande spelas på våra teatrar, Sokrates, Platons och Aristoteles landvinningar inom tankens värld. Detta är

1. Dopamine (DA) is a protective agent in the gastrointestinal (GI) tract in both rats and humans. Therefore, we have studied the site of DA production in rat and human GI tract using a variety of techniques, including immunocytochemistry (ICC), in situ hybridization histochemistry, reverse transcription-polymerase chain reaction, HPLC, western blotting and immunoelectron microscopy. 2. We found v

A noncompetitive flow immunoassay system (FIA) for the analysis of interleukin-8 (IL-8) in cell samples was developed. Affinity interaction assays based on offline incubation of excess labeled antibodies and antigen (IL-8) were carried out. The residual unbound labeled antibody was trapped in an immunoaffinity column with immobilized IL-8 while the immunocomplex, labeled antibody/IL-8, was detecte

Bildtagning med magnetresonans (mangetic resonance imaging eller MRI) är en fascinerande teknik som använder magnetfält och radiovågor för att skapa detaljerade bilder av kroppens innanmäte. Tvärt om mot vad många tror så finns det ingen ”magnetröntgen” i MR-kameran, och därmed ingen skadlig joniserande strålning. Detta gör det möjligt att utföra upprepade undersökningar på friska och sjuka försök

A 37-year-old man sustained occlusion of the right coronary artery after a bicycle accident with blunt chest trauma over the left scapula. Acute coronary angiography was performed because of chest pain and ST-segment elevation. Despite surgically successful acute revascularization the patient developed a transmural inferior wall infarction. Coronary artery occlusion after blunt chest trauma is rar

Clin Microbiol InfectAbstract Propionibacterium acnes is a common and probably underestimated cause of delayed joint prosthesis infection. Bacterial biofilm formation is central in the pathogenesis of infections related to foreign material, and P. acnes has been shown to form biofilm both in vitro and in vivo. Here, biofilm formation by 93 P. acnes isolates, either from invasive infections (n = 45

Aims  In a cohort of men and women with Type 1 diabetes, prospectively followed for > 20 years, vibrotactile sense in fingers was investigated and related to neurophysiological tests, glycaemic level and clinical score. Methods  Out of 58 patients, diagnosed at the age of 15-25 years and recruited 1984-1985, 32 patients (13 women, median age 52 years, range 44-75 years; 19 men, median age 52 years

Atypical hemolytic uremic syndrome has been associated with dysregulation of the alternative complement pathway. In this study, a novel heterozygous C3 mutation was identified in a factor B-binding region in exon 41, V1636A (4973 T > C). The mutation was found in three family members affected with late-onset atypical hemolytic uremic syndrome and symptoms of glomerulonephritis. All three patients

The growth-promoting polyamines are polybasic compounds that efficiently enter cancer cells by as yet incompletely defined mechanisms. Strategies to inhibit their internalization may have important implications in the management of tumor disease. Here, we show that cellular binding and uptake of polyamines are inhibited by a single chain variable fragment anti-heparan sulfate (HS) antibody. Polyam

Popular Abstract in Swedish Avhandlingen berör det så kallade "struktur och rörelse"-problemet som är centralt inom datorseendefältet. Målet är att givet tvådimensionella bilder av ett föremål, kunna återskapa dess tredimensionella form och koordinater i rummet, dvs strukturen, samtidigt med kamerans position relativt objektet i varje bild, dvs rörelsen. Inom robotiken kallas tekniken för "simultaThis thesis presents contributions to structure-and-motion estimation, a central topic in the field of geometric computer vision. In particular, the problem of view planning is considered, and continuous and discrete optimization-based algorithms are given for how to plan the path of a sensor to its destination, while balancing the competing goals of path length and reconstruction accuracy. The sa

Bakgrund och problemformulering: Digitaliseringen har förändrat förutsättningarna för alla detaljhandlare och då även för sporthandlarna. Detta påverkar arbetarnas roll i den fysiska butiken samt vad som krävs av företaget för att fortfarande hålla sig konkurrenskraftiga. Det finns inte fördjupade studier på sportbutiker och avsaknaden finns i hur företagen och framförallt personalen arbetar med k
