Extra-pair paternity in Blue Tits (Cyanistes caeruleus) depends on the combination of social partners' age

There is growing evidence that engaging in extra-pair copulations may be a strategy by which females can modify their initial mate choice if they are constrained by primary choice of the social mate. Several factors such as genetic similarity and adult phenotypic traits can affect extra-pair paternity (EPP) patterns, but the relative importance of these factors may vary among species. Moreover, in

Urea as an Efficient Reagent for the Synthesis of 3-Ethyl-3-(hydroxymethyl)oxetane: A Novel Component in Cationic Ring-Opening Polymerisation

Urea is a very attractive chemical raw material for large-scale production as it combines low cost with virtually unlimited supply and essentially no toxic effects. Here, we present a study on its use in the dehydration of trimethylolpropane with formation of 3-ethyl-3-(hydroxymethyl)oxetane. The reaction consists of carbonylation of trimethylolpropane and subsequent extrusion of carbon dioxide. T

Admixture mapping reveals loci for carcass mass in red deer x sika hybrids in Kintyre, Scotland

We deployed admixture mapping on a sample of 386 deer from a hybrid swarm between native red deer (Cervus elaphus) and introduced Japanese sika (Cervus nippon) sampled in Kintyre, Scotland to search for quantitative trait loci (QTLs) underpinning phenotypic differences between the species. These two species are highly diverged genetically [Fst between pure species, based on 50K single nucleotide p

Socioeconomic Factors and Adherence to CPAP : The Population-Based Course of Disease in Patients Reported to the Swedish CPAP Oxygen and Ventilator Registry Study

Background: Early identification of poor adherence to CPAP treatment is of major clinical importance to optimize treatment outcomes in patients with OSA. Research Question: How do socioeconomic factors influence CPAP adherence? Study Design and Methods: Nationwide, population-based cohort study of patients with OSA receiving CPAP treatment reported to the Swedish quality registry Swedevox between

Non-invasive Urine Test for Molecular Classification of Clinical Significance in Newly Diagnosed Prostate Cancer Patients

Objective: To avoid over-treatment of low-risk prostate cancer patients, it is important to identify clinically significant and insignificant cancer for treatment decision-making. However, no accurate test is currently available. Methods: To address this unmet medical need, we developed a novel gene classifier to distinguish clinically significant and insignificant cancer, which were classified ba

Fatigue in men and women who have returned to work after stroke : Assessed with the fatigue severity scale and mental fatigue scale

Objective: To assess the occurrence of self-reported fatigue among men and women who have returned to work after stroke, and the association between 2 fatigue rating scales. Design: A cross-sectional study. Subjects: A total of 91 adults (58 men/33 women, mean age 53 years) with mild to moderate disability. Methods: Questionnaires were posted to participants approximately one year after stroke. Fa

Short-and long-term clinical outcomes for patients with takotsubo syndrome and patients with myocardial infarction : A report from the swedish coronary angiography and angioplasty registry

BACKGROUND: Takotsubo syndrome (TS) is a potentially life-threatening acute cardiac syndrome with a clinical presentation similar to myocardial infarction and for which the natural history, management, and outcome remain incompletely understood. Our aim was to assess the relative short-term mortality risk of TS, ST-segment–elevation myocardial infarction (STEMI), and non-STEMI (NSTEMI) and to iden

Temporal and Spatial Variabilities of Chemical and Physical Parameters on the Heron Island Coral Reef Platform

Globally, coral reefs are threatened by ocean warming and acidification. The degree to which acidification will impact reefs is dependent on the local hydrodynamics, benthic community composition, and biogeochemical processes, all of which vary on different temporal and spatial scales. Characterizing the natural spatiotemporal variability of sea- water carbonate chemistry across different reefs is

Ryggmärgsskada – ett ovanligt tillstånd med komplexa behov

Spinal cord injury (SCI) challenges many aspects of life. Common secondary health conditions are sensorimotor impairments, autonomic dysfunction affecting bowel, bladder, sexual and cardiovascular function, pressure ulcers, pulmonary dysfunction, pain and psychological distress. Primary rehabilitation and lifelong follow-up from a specialized interdisciplinary rehabilitation team is needed to atta

Photocatalytic nanoparticles – From membrane interactions to antimicrobial and antiviral effects

As a result of increasing resistance among pathogens against antibiotics and anti-viral therapeutics, nanomaterials are attracting current interest as antimicrobial agents. Such materials offer triggered functionalities to combat challenging infections, based on either direct membrane action, effects of released ions, thermal shock induced by either light or magnetic fields, or oxidative photocata

Chiral Selectivity of Secondary Nucleation in Amyloid Fibril Propagation

Chirality is a fundamental feature of asymmetric molecules and of critical importance for intermolecular interactions. The growth of amyloid fibrils displays a strong enantioselectivity, which is manifested as elongation through the addition of monomers of the same, but not opposite, chirality as the parent aggregate. Here we ask whether also secondary nucleation on the surface of amyloid fibrils,

Transcriptome sequencing provides evidence of genetic assimilation in a toad-headed lizard at high altitude

Understanding how organisms adapt to the environment is a compelling question in modern evolutionary biology. Genetic assimilation provides an alternative hypothesis to explain adaptation, in which phenotypic plasticity is first triggered by environmental factors, followed by selection on genotypes that reduce the plastic expression of phenotypes. To investigate the evidence of genetic assimilatio
