Desmoplastic melanoma in Sweden in 2009–2022 : A population-based registry study demonstrating distinctive tumour characteristics, incidence and survival trends

Background: Desmoplastic melanoma (DM) is a rare subtype, accounting for less than 5% of primary cutaneous invasive melanomas. DM often arises in chronically sun-exposed skin, in older individuals. While the incidence of cutaneous melanoma has increased globally, trends specific to DM are less documented and studies on survival outcomes for DM are inconsistent. Objectives: To study patient and tum

Modeling of Metal Particle Combustion : Detailed Numerical Studies of Micron-sized Iron and Aluminum Particles

Metal fuels can be promising candidates as alternative energy sources and renewable energy carriers within the metal-fuel cycle. They feature high energy density, low environmental impact, and broad production and application. One challenge in metal particle combustion lies in its multi-physics complexity compared to traditional hydrocarbon fuels. This thesis intends to investigate the combustion

Att bygga ett kompetenscentrum och en produktionsanläggning samt att bidra till att en marknad skapas : – Två sätt för Helsingborgs stad att utveckla den cirkulära ekonomin

Denna rapport jämför två fall där Helsingborgs stad verkar för att bli mer cirkulär. Det ena är hur avfallsbolaget NSR (där staden är majoritetsägare) har utvecklat en produktionsanläggning och kompetenscentrum om biokol. Det andra är hur Stadsbyggnadskontoret, med Fastighetsförvaltningen, arbetar med att främja återbruk. Rapporten beskriver hur man i dessa två fall har skapat agendasättande relatDenna rapport jämför två fall där Helsingborgs stad verkar för att bli mer cirkulär.

Researchers of the far right as intersectional subjects: Three arenas for emotional labour

This conceptual article examines the relational dynamic between the research field focusing on the far right and those critical scholars that endeavour to undertake these studies. It is theoretically anchored in the field of political science scholarship that recognises the key role played by gender in understanding both the ideological underpinnings and the workings of various far-right entities

Encountering children with suspected neurodevelopmental disorders in Child Health Services : Swedish nurses' experiences

Purpose: To describe nurses' experiences encountering children with suspected neurodevelopmental disorders in Child Health Services. Design and methods: This qualitative inductive study was conducted in Sweden. Twenty nurses were interviewed individually on a virtual platform using a semi-structured interview guide with open-ended and explorative questions. Interviews were audio recorded and trans

Neurodevelopmental brain reserve in behavioural variant Frontotemporal Dementia

Background: Behavioural variant Frontotemporal Dementia (bvFTD) is an early-onset dementia characterised by early anterior cingulate (AC) neuropathological insult. The AC exhibits high morphological heterogeneity, which may be classified according to the presence of a paracingulate sulcus (PCS), a tertiary sulcus that, when present, develops during the third gestational trimester and thereafter re

Alcohol impairs learning and timing of conditioned eyeblink responses

Alcohol impairs motor performance, but it remains unclear precisely why this is the case. Here, we examine the effects of alcohol intoxication on conditioned eyeblink responses, a form of classical conditioning dependent on the cerebellum. In experiment 1, the conditioned responses of 18 students before and after alcohol consumption up to 1 ‰ were compared against the performance of 26 non-drinkin

”Vad väntar efter supervalåret 2024?”

Utfallet av parlamentsvalen i Europa får troliggen större påverkan på Sverige än Trump, skriver Fredrik N G Andersson, docent i nationalekonomi vid Lunds universitet.

Reduction of artifacts associated with missing data in coherent diffractive imaging

Coherent diffractive imaging experiments often collect incomplete datasets containing regions that lack any measurements. These regions can arise because of beamstops, gaps between detectors, or, in tomography experiments, a missing wedge of data due to a limited sample rotation range. We describe practical and effective approaches to mitigate reconstruction artifacts by bringing uniqueness back t

On the origin of an insular hybrid butterfly lineage

new species can form through hybridization between species. Hybrid speciation in animals has been intensely debated, partly because hard evidence for the process has been difficult to obtain. Here we report the discovery of a European hybrid butterfly lineage, a finding that can be considered surprising given the intense and long-term study of European butterflies. The lineage we describe is main

PopGLen-A Snakemake pipeline for performing population genomic analyses using genotype likelihood-based methods

SUMMARY: PopGLen is a Snakemake workflow for performing population genomic analyses within a genotype-likelihood framework, integrating steps for raw sequence processing of both historical and modern DNA, quality control, multiple filtering schemes, and population genomic analysis. Currently, the population genomic analyses included allow for estimating linkage disequilibrium, kinship, genetic div

Defining Excellence : The First Core Set of Quality Indicators for the European Paediatric Surgical Audit on Hirschsprung's Disease Care

Aim: This study aimed to develop a universally applicable core set of quality indicators for Hirschsprung's disease care through a consensus-driven process, to standardise and improve care quality across Europe. Methods: A modified Delphi method was used to achieve consensus among healthcare professionals (HPs) and patient representatives (PRs) across Europe. Participants completed three rounds of

Affordances and Limitations of Translanguaging and Writing Tools : A Study of Emergent Multilingual Students' Writing in EFL

Multilingual students writing in English as a foreign/second language has been a major topic in research for many years (see Leung & Valdés for overview). This topic is particularly relevant in Sweden, as reports suggest that students who are speakers of a language other than Swedish (LOTS) in the home have a lower grade average after 9 years of compulsory schooling (Skolinspektionen, 2010; Sk

Balancing inflammation : the specific roles of serum amyloid A proteins in sterile and infectious diseases

Serum Amyloid A (SAA) proteins are acute-phase reactants with critical roles in sterile and bacterial inflammation. Through in vitro and in vivo experiments, we demonstrate that SAA proteins amplify cytokine and chemokine responses during sterile inflammation and enhance bacterial clearance in infectious conditions. Mechanistically, SAA proteins augment NF-κB signaling, driving pro and anti-infl

Regeneration of dimethyl carbonate and purification of 5-hydroxymethylfurfural used in a biphasic dehydration process through activated carbon adsorption and evaporation

The production of 5-hydroxymethylfurfural (HMF) is an important process for a future sustainable plastic industry. Hence many processes were developed to produce HMF, however, HMF recovery and solvent recyclability are limiting steps for the process development. Therefore, In this study, granulated activated carbon (GAC) was investigated as a purification step of HMF produced from fructose in a bi

Flexiblare finansregler med tveksam effekt

Många EU-länder kämpar med svaga offentliga finanser och i stora euroländer som Frankrike och Italien är den offentliga skulden över 100 procent av BNP. Trots strikta finanspolitiska regler har få länder lyckats hålla sina statsfinanser i schack – inte ens Tyskland. År 2024 reviderades reglerna i förhoppningen att det skall leda till mer robusta offentliga finanser i framtiden. Frågan är: löser de

Soluble cerebral Aβ protofibrils link Aβ plaque pathology to changes in CSF Aβ42/Aβ40 ratios, neurofilament light and tau in Alzheimer’s disease model mice

The Aβ42/Aβ40 ratio in the cerebrospinal fluid (CSF) and the concentrations of neurofilament light (NfL) and total tau (t-tau) are changed in the early stages of Alzheimer’s disease (AD)1, but their neurobiological correlates are not entirely understood. Here, we used 5xFAD transgenic mice to investigate the associations between these CSF biomarkers and measures of cerebral Aβ, including Aβ42/Aβ40

Heart rate response and recovery in cycle exercise testing : normal values and association with mortality

Aims. Chronotropic incompetence and impaired heart rate (HR) recovery are related to mortality. Guidelines lack specific reference values for HR recovery. We defined normal values and studied blunted HR response and recovery and mortality risk. Methods and results. We included 9917 subjects (45% females) aged 18–85 years who performed a cycle exercise test. We defined normal values for peak HR, HR
