The Paleocene-Eocene Thermal Maximum (PETM, ca. 56 Ma) is marked by a negative carbon isotope excursion (CIE) and increased global temperatures. The CIE is thought to result from the release of 13C-depleted carbon, although the source(s) of carbon and triggers for its release, its rate of release, and the mechanisms by which the Earth system recovered are all debated. Many of the proposed mechanis

Here we report on the impact of reducing the crystalline size on the structural and magnetic properties of γ-Fe2O3 maghemite nanoparticles. A set of polycrystalline specimens with crystallite size ranging from ~2 to ~50 nm was obtained combining microwave plasma synthesis and commercial samples. Crystallite size was derived by electron microscopy and synchrotron powder diffraction, which was used

Background Although previous studies suggest similar patient survival for peritoneal dialysis (PD) and haemodialysis (HD), PD use has decreased worldwide. We aimed to study trends in the choice of first dialysis modality and relate these to variation in patient and technique survival and kidney transplant rates in Europe over the last 20 years. Methods We used data from 196 076 patients within the

Objectives: To validate the performance of the most commonly used formulas for estimation of glomerular filtration rate (GFR) against measured GFR during the index hospitalisation for ST-elevation myocardial infarction (STEMI). Setting: Single centre, methodological study. Participants: 40 patients with percutaneous coronary intervention-treated STEMI were included between November 2011 and Februa

The objective of this study was to evaluate the main characteristics of adult male offenders convicted of rape or aggravated rape against adult females. We reviewed all convictions (n = 21) based on court documents from the District Court, the Court of Appeal and information from the Swedish Tax Agency in Malmö, Sweden, between 2013 and 2018. The findings indicated that the most common offender ch

The mechanisms responsible for the structure and evolution of technological systems are not fully understood. This study examines the network of supply and use of significant innovations across industries in Sweden, 1970-2013. The results suggest that at least 30% of innovation patterns can be statistically predicted by network stimulus from both backward and forward linkages in the Swedish econom

Purpose: The aim of the study was to investigate the participating psychologists’ experiences with compassion fatigue, and to identify individual, interpersonal, and organizational factors and strategies perceived as contributing or protecting in relation to compassion fatigue. Methods: Semi-structured telephone interviews were conducted with eight psychologists (three men and five women) with mor

På 1940-talet började Kyrkohistoriska arkivet vid Lunds Universitet arbeta med att klarlägga förändringar i den samtida kyrkliga seden. Insamlingen av sådana uppgifter fann sin form på 1960-talet, då arkivet började sända ut rikstäckande frågelistor om den aktuella kyrkliga seden. Genom dessa LUKA-listor har den kyrkliga seden inventerats för hela landet med jämna mellanrum från och med 1962. År 2

Recent research showed that exposure to the vaccine against polio in early life had no long-term economic benefits among native Swedes. However, whether this result holds for individuals from other countries remains unexplored. This study explores the relationship between exposure to the vaccine and later-life outcomes, but focuses on individuals who migrated to Sweden (birth cohorts 1946–1971), a

Obestatin is a gastrointestinal peptide having wide-ranging effects on cell proliferation; however, its mechanism of action remains poorly understood. Thus, the aim of the study was to elucidate the effect of exogenous obestatin on the postnatal structural development of the small intestine. Seven-day-old piglets with an average BW of 1.56 ± 0.23 kg were divided into four groups (n = 10) that rece

It is well-known that use of continuous systemic corticosteroids (SG) affects bone metabolism, bone mineral density (BMD), and ultimately increases the risk of osteoporosis. In patients with asthma, on the other hand, the effects of long-term high-dose inhaled corticosteroids (ICS) on BMD and risk of osteoporotic fractures is controversial. The reasons for this inconsistency could be explained by

The existing information supports the use of this material as described in this safety assessment. p-α,α-Trimethylbenzyl alcohol was evaluated for genotoxicity, repeated dose toxicity, reproductive toxicity, local respiratory toxicity, phototoxicity/photoallergenicity, skin sensitization, and environmental safety. Data show that p-α,α-trimethylbenzyl alcohol is not genotoxic. The repeated dose, re

Recent advances in obtaining reduced representation libraries for next-generation sequencing permit phylogenomic analysis of species-rich, recently diverged taxa. In this study, we performed sequence capture with homemade PCR-generated probes to study diversification among closely related species in a large insect genus to examine the utility of this method. We reconstructed the phylogeny of Nepti
