Objective This study aims to investigate whether oral fluoroquinolone use is associated with an increased risk of aortic and mitral valve regurgitation. Design A nationwide cohort study based on linked healthcare register data encompassing patient characteristics, prescription data and cases of aortic and mitral valve regurgitation. Setting Sweden, 2006–2018. Participants Study participants were a
Chronic breathlessness is a dominating symptom that restricts daily life for many people with cardiorespiratory disease [1]. Different dimensions of the symptom, such as the intensity, sensory qualities and emotional responses, can be assessed using the instruments Dyspnea-12 (D-12) [2] and the Multidimensional Dyspnea Profile (MDP) [3], which share similarities in the underlying constructs of wha
We have studied the geometry and electronic structure of the P-cluster in nitrogenase in four oxidation states: PN, P1+, P2+, and P3+. We have employed combined quantum mechanical and molecular mechanical (QM/MM) calculations, using two different density-functional theory methods, TPSS and B3LYP. The calculations confirm that the side chain of Ser-188 is most likely deprotonated in the partly oxid
The proto-oncogene SKI is highly expressed in human myeloid leukemia and also in murine hematopoietic stem cells. However, its operative relevance in these cells remains elusive. We have over-expressed SKI to define its intrinsic role in hematopoiesis and myeloid neoplasms, which resulted in a robust competitive advantage upon transplantation, a complete dominance of the stem and progenitor compar
In this work, we study the problem of estimating the in-ear sound field using microphone measurements at nearby positions. Typically, the sound field is first interpolated to the position of the head under free-field assumptions, followed by filtering through pre-measured head-related transfer functions (HRTFs). While properties of free-field interpolation methods have been well studied with respe
Although spatial resolution in fluorescence microscopy and related fields has advanced to the nanometer scale, time resolution has remained essentially unchanged and is set by the camera system’s imaging time. Yet adequate time resolution is crucial for information acquisition about, for instance, dynamical processes in cells. This acquisition typically proceeds by analyzing biomolecular trajector
Electric power is the foundation of modern society, yet Europe is currently facing an energy crisis, increasing interest in power generation, energy infrastructure, and grid resilience. However, power plant data are complex and multidimensional, making it difficult to gain an overview or understanding. Visualization methods can help to reduce cognitive load and facilitate exploration of such data.
Background Exertional breathlessness is a limiting symptom that often coexists with anxiety and depression. We tested the hypothesis that anxiety and depression negatively impact exertional breathlessness in daily life and during standardised cardiopulmonary exercise testing (CPET). Methods Analysis of people aged ⩾40 years undergoing incremental cycle CPET. Exertional breathlessness in daily life
Limited epidemiological evidence suggests a protective role for plant foods rich in flavonoids and antioxidants in hepatocellular cancer (HCC) etiology. Our aim was to prospectively investigate the association between dietary intake of flavonoids, lignans and nonenzymatic antioxidant capacity (NEAC) and HCC risk. Data from the European Prospective Investigation into Cancer and Nutrition (EPIC) coh

Changes in understory biomass, forest floor carbon (C) stock and vegetation composition were studied in six age-classes of Siberian larch (Larix sibirica) and two age-classes of native birch (Betula pubescens) in Iceland. The ground vegetation was less in the larch during the thicket stage and in the old-growth birch compared to a treeless pasture. Understory biomass was strongly related to canopy
A series of palladium(II) and platinum(II) complexes ([PdCl2(J003)] (1), [PdCl2(W001)] (2), [PtCl2(J003)] (3) and [PtCl2(W001)] (4), where J003 = the Josiphos ligand (R)-1-[(S)-2-diphenylphosphino)ferrocenyl]ethyldicyclohexylphosphine and W001 = the Walphos ligand (R)-1[(R)-2-(2'-diphenylphosphinyl) ferrocenyl]ethyldo(bis-3,5-trifluoromethylphenyl)phosphine), were prepared from the reaction of the
Popular Abstract in Swedish Diabetes kännetecknas av förhöjda halter av glukos i blodet och flera vanliga former förekommer. Typ 1 (T1D) diabetes är vanligast förekommande hos barnoch ungdomar och karakteriseras av att de insulin producerande cellerna (s.k. betacellerna) förstörs av kroppens eget immunförsvar, en autoimmun reaktion. Patienter med T1D diabetes kräver insulin för överlevnad och har T1D is most common in children and young adults and is characterized by autoimmune destruction of insulin producing pancreatic beta cells, presence of certain risk genotypes such as HLA-DQB1, INS VNTR, PTPN22 and need of insulin for survival. In adults the same situation is often referred to as Latent Autoimmune Diabetes in Adults (LADA), with age at onset after 35 years and non-insulin requiring
Information on the density (p) and refractive index m(=n-ik) of elemental carbon (ECa) and organic matter (OMa), the main carbon components of atmospheric aerosols, has frequently been obtained from closure calculations between physical and chemical aerosol properties. However, this approach has suffered from large uncertainties since there were more unknown (or poorly known) parameters than defin
Deep-seated lipomas are often atypical histologically and are considered by some to have a high risk of recurrence after excision. We reviewed 215 deep-seated lipomas of the extremities and trunk wall with reference to histology, cytogenetics, clinical features and local recurrence. We classified tumours with atypical features and/or ring chromosomes as atypical lipomas. These were more common in
Vitamin C is an antioxidant and inhibitor of carcinogenic N-nitroso compound production in the stomach. Higher dietary vitamin C consumption is associated with decreased risk of gastric cancer (GC) in numerous case-control studies, but data from prospective studies are limited, particularly so for blood measures of vitamin C. The objective of this study was to determine the association of plasma a
We review the potential of isothermal calorimetry as an analytical tool to provide an integrated view of the effect of different processing steps on the quality and shelf life of minimally processed fruits and vegetables. Variations in processing operations involved in product development in the food industry are studied through a factory scenario to show the versatility of the technique in monito
Somatostatin (SST) is a peptide hormone active in the regulation of the endocrine system via different somatostatin receptors subtypes. It inhibits the release of multiple secondary peptide hormones, affecting neurotransmission and cell proliferation. SST has a high therapeutic potential in the treatment of disease, such as acromegali, acute pancreatitis and gastroenteropathic endocrine tumors. Ho
