Enzymes are dynamic entities, and their conformational dynamics are intimately linked to their function and evolvability. In this context, protein tyrosine phosphatases (PTPs) are an excellent model system to probe the role of conformational dynamics in enzyme function and evolution. They are a genetically diverse family of enzymes, with a highly conserved catalytic domain, identical catalytic mec

Discovering topological quantum materials that combine nontrivial topology with large bandgaps and experimentally accessible signatures remains a central pursuit in condensed matter physics. We demonstrate, through first-principles calculations and tight-binding modeling, that pyrite-type osmium disulfide (OsS2) is a fragile topological insulator (FTI) characterized by an exceptionally large direc

Background: Health system performance assessment helps identify areas for improvement and guides policy initiatives. Although well-validated indicators exist for measuring organ donation and transplantation performance at the facility level, consensus on indicators for assessing national programmes is lacking. The aim of this study was to develop a comprehensive scorecard for evaluating national o

Introduction: Despite increasing recognition of pediatric acute-onset neuropsychiatric syndrome (PANS), its neuropsychological underpinnings remain limited, particularly in relation to obsessive-compulsive disorder (OCD) symptoms. PANS manifests abruptly with severe OCD and/or eating restrictions alongside concurrent neuropsychiatric symptoms, causing distress and functional impairment. This study

Fire has shaped terrestrial ecosystems for hundreds of millions of years. Human activities dramatically shift natural fire regimes, leading to adverse conservation impacts that are projected to increase in severity. Many animals appear ill-equipped to face these drastic changes, and they may be unable to adapt rapidly enough. In contrast, behavioural plasticity could offer a faster solution to ach

Second primary malignancies (SPMs) increasingly affect mantle cell lymphoma (MCL) survivors. In nationwide Danish and Swedish cohorts (2000–2020), we evaluated overall survival among MCL patients with SPMs versus matched non-lymphoma individuals with comparable malignancies and MCL patients without SPMs, respectively. Of 3094 MCL survivors, 19% in Denmark and 15% in Sweden developed an SPM, with a

Aims. We investigate the formation and evolutionary trajectory of the Milky Way’s inner and outer galactic regions using stars from open clusters in the Gaia-ESO OC survey. Methods. Using numerical simulations from Chempy, we leveraged Markov chain Monte Carlo sampling techniques to derive galactic evolutionary parameters for each open cluster by fitting measured abundances of elements C, N, O, Mg

Moult, the regular replacement of feathers, is a resource-intense avian annual-cycle stage. Resource allocation to support feather regrowth may require downregulation of other physiological processes, such as immune function, which is critical for preventing disease-related mortality. At the same time, the emergence of new feathers may increase the risk of skin injury and infection, potentially re

Objective: The aim of this study was to investigate the experiences of school nurses working with refugee children from Ukraine. Design: This research was conducted as a qualitative interview study, using an inductive approach and a semi-structured interview guide. Sample: School nurses (n = 8) from different parts of Sweden were interviewed, and the data were analyzed through a qualitative conten

Objectives The aim was to estimate the prevalence and risk of respiratory symptoms among workers exposed to epoxy resin systems in the wind turbine industry. Methods We conducted a cross-sectional study including 180 epoxy-exposed production workers from two Danish wind turbine blade factories and 41 non-exposed office workers. Respiratory symptoms were defined as having two or more symptoms (i.e.

Background: The prognostic benefit of percutaneous coronary intervention (PCI) for chronic total occlusion (CTO) in stable coronary artery disease (CAD) remains uncertain. Objectives: To evaluate long-term survival following CTO PCI compared with medical therapy (MT) using target trial emulation and a nationwide real-world registry. Methods: We included 7813 patients with stable CAD and a document

Aim: The aim of this study was to describe the routines for handling mother's own milk and donor human milk in Swedish neonatal care units related to national guidelines. Methods: A web-based survey of 24 of 38 neonatal units and 19 of 28 human milk banks in Sweden. Results: Despite national guidelines, breast milk handling varied widely. All units offered lactation support and free breast pumps d

Aim: An electrocardiogram is commonly recommended in breath-holding spell management, mainly to rule out long QT syndrome. This retrospective study investigated the risk of long QT syndrome being misdiagnosed as breath-holding spells in a paediatric population in southern Sweden. Methods: Data on patient characteristics and diagnostic findings were reviewed for patients aged < 10 years who were di

Inhalation administration of therapeutics is a crucial method for treatment of respiratory diseases, offering direct access to the target organ. However, the progression of candidate drugs is frequently impacted by clinical dose level limitations due to lung histopathological findings or functional effects identified in in vivo studies. Addressing these safety concerns is crucial in advancing comp

Objective: Worse women's outcomes after elective standard endovascular aneurysm repair have been widely reported. Similar data have surfaced from cohorts undergoing fenestrated and branched repair; however, studies reporting from a sex perspective are rare and mostly limited to single centre designs. This study aimed to examine survival following nationwide complex endovascular repair according to

In this paper, we investigate how institutional conditions shape individual-level resilience in healthcare organizations which in turn facilitates the intrapreneurial behavior of healthcare professionals. Using a critical literature review methodology, we identify that the current literature centers around three dominant clusters defined by intrapreneurial outcomes: organizational performance, inn

Objectives: To evaluate the test–retest reliability of a novel laboratory-based protocol for inducing and measuring head acceleration in multiple directions under anticipated and unanticipated conditions. Design: Laboratory-based test–retest reliability study. Methods: Thirty physically active adults (50% female) completed standardized head perturbations using a custom-built apparatus. Perturbatio

In previous work we have shown that any subalgebra A⊆K[x] of finite codimension n can be described by a finite set Sp(A), called the subalgebra spectrum of A, together with n defining conditions. In this paper we show that a similar result applies to subalgebras of infinite codimension. We also develop new tools for the case of finite codimension. One of them is to introduce an ideal I(A) in A of
