Understanding how environmental variation drives phenotypic diversification within species is a major objective in evolutionary biology. The seaweed fly Coelopa frigida provides an excellent model for the study of genetically driven phenotypes because it carries an α/β inversion polymorphism that affects body size. Coelopa frigida inhabits highly variable beds of decomposing seaweed on the coast i

Background: Revascularization is a treatment option for patients with intermittent claudication. However, there is a lack of evidence to support its long-term benefits and cost-effectiveness. The aim of this study was to compare the cost-effectiveness of revascularization and best medical therapy (BMT) with that of BMT alone. Methods: Data were used from the IRONIC (Invasive Revascularization Or N

A search for new charged massive gauge bosons, W′, is performed with the ATLAS detector at the LHC. Data were collected in proton–proton collisions at a center-of-mass energy of s=13 TeV and correspond to an integrated luminosity of 36.1 fb−1. This analysis searches for W′ bosons in the W′→tb¯ decay channel in final states with an electron or muon plus jets. The search covers resonance masses betw

Multipotent progenitor cells confirm their T cell–lineage identity in the CD4–CD8– double-negative (DN) pro-T cell DN2 stages, when expression of the essential transcription factor Bcl11b begins. In vivo and in vitro stage-specific deletions globally identified Bcl11b-controlled target genes in pro-T cells. Proteomics analysis revealed that Bcl11b associated with multiple cofactors and that its di

The standardization of writing styles and formats and the use of jargon in the social sciences have had considerable consequences on the quality of academic work. Due to the emphasis on method, theory, and empirical rigor, creativity, personal narrative, and storytelling no longer play a large role in academic writing. Addressing the growing concern for researchers losing their sense of self, the

Habitat structural complexity affects the behaviour and physiology of individuals, and responses to the environment can be immediate or influence performance later in life through delayed effects. Here, we investigated how structural enrichment, both pre-release in the hatchery rearing environment and post-release in the wild, influenced winter growth and site fidelity of brown trout stocked into

Background: Data on rescue treatment of autoimmune hepatitis in patients that fail standard treatment are sparse. Aims: To report our long-term experience with mycophenolate mofetil. Methods: Retrospective study in 22 patients with autoimmune hepatitis who failed azathioprine and prednisolone due to adverse events (n = 14, 64%), lack of remission (n = 5, 23%) or a combination (n = 3, 13%). Results

Objective: The effectiveness of golimumab in Crohn’s disease (CD) is largely unknown as it is not approved for the treatment of the disease. We aimed to identify the population of CD patients treated with golimumab in Sweden, to assess the effectiveness of golimumab (defined as the drug retention rate), and to identify predictors of drug discontinuation. Methods: Patients with CD who received at l

Authoritative school climates have been associated with less school bullying and other antisocial behaviors. However, studies focusing on the classroom level, as well as on bystander behaviors, are lacking. The aim of the current study was to examine whether authoritative classroom climates were associated with bullying victimization and various bystander behaviors (reinforcer, outsider, and defen

Importance: Whether certain weather conditions modulate the onset of myocardial infarction (MI) is of great interest to clinicians because it could be used to prevent MIs as well as guide allocation of health care resources. Objective: To determine if weather is associated with day-to-day incidence of MI. Design, Setting, and Participants: In this prospective, population-based and nationwide setti

African ball-rolling dung beetles can use their front legs for multiple purposes that include walking, manipulating or forming a dung ball, and also transporting it. Their multifunctional legs can be used as inspiration for the design of a multifunctional robot leg. Thus, in this paper, we present the development of real robot legs based on the study of the front legs of the beetle. The leg moveme

Introduction: The complement system is essential for an adequate immune response. Much attention has been given to the role of complement in disease. However, to better understand complement in pathology, it is crucial to first analyze this system under different physiological conditions. The aim of the present study was therefore to investigate the inter-individual variation in complement activit

A combination of the searches for pair-produced vectorlike partners of the top and bottom quarks in various decay channels (T→Zt/Wb/Ht, B→Zb/Wt/Hb) is performed using 36.1 fb-1 of pp collision data at s=13 TeV with the ATLAS detector at the Large Hadron Collider. The observed data are found to be in good agreement with the standard model background prediction in all individual searches. Therefore,

Importance: Prenatal exposure to phthalates has been associated with neurodevelopmental outcomes, but little is known about the association with language development. Objective: To examine the association of prenatal phthalate exposure with language development in children in 2 population-based pregnancy cohort studies. Design, Setting, and Participants: Data for this study were obtained from the

Purpose: Daytime sleepiness, a frequent symptom of obstructive sleep apnea (OSA), can impact functional status. In patients with coronary artery disease (CAD) and concomitant OSA, the distinction between sleep-related functional impairment from underlying CAD versus OSA is unclear. This study evaluated the impact of OSA on sleep-related functional impairment in patients with CAD and compared the e

OBJECTIVES: To analyse subdural haemorrhage (SDH) during infancy in Sweden by incidence, SDH category, diagnostic distribution, age, co-morbidity, mortality, and maternal and perinatal risk factors; and its association with accidents and diagnosis of abuse.METHODS: A Swedish population-based register study comprising infants born between 1997 and 2014, 0-1 years of age, diagnosed with SDH-diagnose
