PURPOSE: To evaluate whether MRI signal and T2* measurements of lung tissue acquired at ultrashort detection times (tds) can detect emphysematous changes in lungs.MATERIALS AND METHODS: MR signal intensity of in vivo mouse lungs was measured at 4.7 T at tds of 0.2 and 0.4 msec using single-point imaging (SPI). T2* was calculated from the measurements obtained at the two tds. Two groups of 8- and 3
For studies of how birds control their altitude, seabirds are of particular interest because they forage offshore where the visual environment can be simply modelled by a flat world textured by waves then generating only ventral visual cues. This study suggests that optic flow, i.e. the rate at which the sea moves across the eye's retina, can explain gulls' altitude control over seas. In particula
The use of clinical autopsy has been in decline for many years throughout healthcare systems of developed countries despite studies showing substantial discrepancies between autopsy results and pre-mortal clinical diagnoses. We conducted a study to evaluate over time the use and results of clinical autopsies in Sweden. We reviewed the autopsy reports and autopsy referrals of 2410 adult (age > 17)
The momentum measurement capability of the ATLAS muon spectrometer relies fundamentally on the intrinsic single-hit spatial resolution of the monitored drift tube precision tracking chambers. Optimal resolution is achieved with a dedicated calibration program that addresses the specific operating conditions of the 354 000 high-pressure drift tubes in the spectrometer. The calibrations consist of a
Iron N-heterocyclic carbene (NHC) complexes have received a great deal of attention recently because of their growing potential as light sensitizers or photocatalysts. We present a sub-ps X-ray spectroscopy study of an FeIINHC complex that identifies and quantifies the states involved in the deactivation cascade after light absorption. Excited molecules relax back to the ground state along two pat
Impaired lung function is often caused by cigarette smoking, making it challenging to disentangle its role in lung cancer susceptibility. Investigation of the shared genetic basis of these phenotypes in the UK Biobank and International Lung Cancer Consortium (29,266 cases, 56,450 controls) shows that lung cancer is genetically correlated with reduced forced expiratory volume in one second (FEV1: r
BACKGROUND: Although lifestyle factors have been studied in relation to individual non-communicable diseases (NCDs), their association with development of a subsequent NCD, defined as multimorbidity, has been scarcely investigated. The aim of this study was to investigate associations between five lifestyle factors and incident multimorbidity of cancer and cardiometabolic diseases. METHODS: In thi
Sterols regulate several physico-chemical properties of biological membranes that are considered to be linked to function. Ergosterol is the main sterol molecule found in the cell membranes of yeasts and other fungi. Like the cholesterol found in mammalian cells, ergosterol has been proposed to have an ordering and condensing effect on saturated phospholipid membranes. The effects of cholesterol h
Earlier studies have implied a change in dietary habits of the Swedish population towards a low carbohydrate, high fat diet. Questions have been raised about the development in recent years and potential health effects. We have investigated the dietary intake of Swedish female students enrolled in a university nutrition course between 2002 and 2017. The students carried out self-reporting of all f
In a population-based case-control study in Sweden on multiple myeloma, the occurrence of different diseases in relatives, particularly hematologic malignancies and different types of cancer, was investigated. Through a questionnaire mailed to all living subjects, i.e. cases and controls, and to the next-of-kin for deceased subjects, information was obtained on malignant and certain other diseases
Based on an analytical overview of post-Communist civil society development in Russia, the present thesis attempts a critical discussion of general civil society theory from the perspective of its relevance for the case study in question. The text consists of three closely interconnected, mutually reinforcing parts. In the first part, major issues of current civil society research are being themat
Floriculture industry is very dynamic in its varieties and trade volumes demonstrating 6 to 9 % of annual growth. It gets also more and more diverse in terms of global actors. Now there are about 120 countries actively involved in the floriculture industry as global manufactures with the Netherlands as an epicentre of world flower production and distribution. In that respect, analysis of the flori
Populärvetenskaplig sammanfattning: För drygt 500 miljoner år sedan var Sverige beläget söder om ekvatorn och utgjorde tillsammans med resten av Skandinavien och östra Europa en kontinent kallad Baltica. Vid denna tid, under den period som kallas kambrium, var klimatet ganska kallt. I början av kambrium började havet stiga upp över Baltica så att dagens Skåne, samt övriga delar av Sverige, täcktes
