Background:cThe risk of coronavirus (COVID-19) can be affected by the presence of certain chronic conditions. It is unknown if individuals with severe hereditary alpha-1-antitrypsin deficiency (AATD) faced an increased risk of severe COVID-19 infection during the pandemic and if COPD in this population affected the risk of severe COVID-19 outcomes. Aim: Our aim was to investigate COVID-19 outcomes
Copper complexes supported by benzimidazole-based tetradentate neutral ligands featuring thio- and selenoether donors, resemble the coordination environment of the active site in copper dependent monooxygenases Dopamine-β-monooxygenase (DβM) and peptidylglycine-α-hydroxylating monooxygenase (PHM). The cuprous complexes react with O2 at low temperature generating a reactive copper-oxygen species as
Context: The role of glucagon-like peptide-1 (GLP-1) in type 2 diabetes (T2D) and obesity is not fully understood. Objective: We investigate the association of cardiometabolic, diet, and lifestyle parameters on fasting and postprandial GLP-1 in people at risk of, or living with, T2D. Methods: We analyzed cross-sectional data from the two Innovative Medicines Initiative (IMI) Diabetes Research on P
With the introduction of x-ray free electron laser sources around the world, new scientific approaches for visualizing matter at fundamental length and time-scales have become possible. As it relates to magnetism and ‘magnetic-type’ systems, advanced scattering methods are being developed for studying ultrafast magnetic responses on the time-scales at which they occur. We describe three capabiliti
Amyloid protein deposits are the hallmark of neurodegenerative diseases such as Alzheimer’s, Parkinson’s, or diabetes type II. Although their connection to the diseases is not fully understood, many studies point at intermediate species called oligomers as being the main responsible for the toxicity of these proteins. This makes them strong candidates as therapeutic targets. However, due to their
Objective: The objective of this study was to study the recovery from, and incidence of, work-restricting musculoskeletal pain after bariatric surgery compared with usual obesity care. Methods: Pain in different body regions was monitored using questionnaires in the nonrandomized, prospective, controlled Swedish Obese Subjects (SOS) study, which included 2007 participants treated with bariatric su
Identifying patients at risk for metastatic relapse is a critical medical need. We identified a common missense germline variant in proprotein convertase subtilisin/kexin type 9 (PCSK9) (rs562556, V474I) that is associated with reduced survival in multiple breast cancer patient cohorts. Genetic modeling of this gain-of-function single-nucleotide variant in mice revealed that it causally promotes b
Context: Proneurotensin (pNT) is associated with obesity and type 2 diabetes (T2D), but the effects of Roux-en-Y gastric bypass (RYGB) on postprandial pNT levels are not well studied. Objective: This work aimed to assess the effects of RYGB vs a very low-energy diet (VLED) on pNT levels in response to mixed-meal tests (MMTs), and long-term effects of RYGB on fasting pNT. Methods: Cohort 1: Nine no
Objective: To investigate whether the first wave of the COVID-19 pandemic impacted healthcare consultations (HCC) and hospitalization among people with and without osteoarthritis (OA).Methods: Using register data, we included individuals aged ≥35 years residing in Skåne region, Sweden, during 2009-2019 with (n = 123,523) and without (n = 552,412) a diagnosis of OA during January 1, 2009-Decemb
Nickel-based superalloys are known to be difficult to machine. These alloys are generally machined with cemented carbide tools under low productivity process conditions. Superhard polycrystalline cubic boron nitride (PcBN) tooling offers the possibility of increased production rates, however, a thorough understanding of the material performance and degradation is required before a transition from
Metal halide perovskites have shown a great performance in a broad range of optoelectronic devices. The variety of preparation methods makes perovskites especially attractive, yet preparation of complex nanostructures based on these materials remains challenging. Here we present a template assisted method allowing to achieve any pre-designed arrangement of methylammonium lead triiodide (MAPbI3) po
The self-assembly of amyloid β peptide (Aβ) to fibrillar and oligomeric aggregates is linked to Alzheimer’s disease. Aβ binders may serve as inhibitors of aggregation to prevent the generation of neurotoxic species and for the detection of Aβ species. A particular challenge involves finding binders to on-pathway oligomers given their transient nature. Here we construct two phage–display libraries
Despite a large number of studies, out of all drivers of radiative forcing, the effect of aerosols has the largest uncertainty in global climate model radiative forcing estimates. There have been studies of aerosol optical properties in climate models, but the effects of particle number size distribution need a more thorough inspection. We investigated the trends and seasonality of particle number
Optoelectronic devices based on metal halide perovskites continue to show a improved performance, and solution-based coating techniques pave the way for large-area applications. However, not all parameters influencing the thin film formation process of metal halide perovskites are identified and entirely rationalised over their full compositional range, thus hampering optimised thin film fabricati
Flip-flop processes due to magnetic dipole-dipole interaction between neighboring ions in crystals doped by rare-earth ions are one of the mechanisms of relaxation between hyperfine levels. Modeling of this mechanism has so far been macroscopic, characterized by an average rate describing the relaxation of all ions. Here, however, we present a microscopic model of flip-flop interactions between in
Rapid-eye movement (REM) sleep behavior disorder (RBD), enactment of dreams during REM sleep, is an early clinical symptom of alpha-synucleinopathies and defines a more severe subtype. The genetic background of RBD and its underlying mechanisms are not well understood. Here, we perform a genome-wide association study of RBD, identifying five RBD risk loci near SNCA, GBA, TMEM175, INPP5F, and SCARB
Many species up- or downregulate their resting metabolic rate (RMR) when they encounter favourable or unfavourable feeding conditions, respectively. This is thought to promote faster growth when food is abundant and conserve energy reserves when food is scarce. The time it takes to express metabolic plasticity remain little studied. Here, we develop a conceptual model showing how rapid or slow met
