Bakgrund: Universitetsstudenter är en grupp som riskerar för mycket stillasittande och akademisk stress. Fysisk aktivitet och träning har i många studier visat sig ge positiv eff ekt såväl fysiskt som psykiskt och kan fungera som stressreduktion. För att få dessa goda eff ekter fi nns det rekommendationer för vuxna gällande fysisk aktivitet att uppnå per vecka. Syfte/frågeställningar: Syftet var a

Bakgrund: Artros är en degenerativ sjukdom som påverkar hela leden. Det är den mest förekommande kroniska muskuloskeletala sjukdomen, där knä är bland den vanligaste påverkade leden. Det finns ingen behandling som botar artros. De behandlingar som rekommenderas syftar till att öka livskvalité, förbättra funktion och minska smärtproblematik. Grundbehandlingen vid knäartros består av patientutbildni

Bakgrund: Utbrändhet, klassificerad som utmattningssyndrom (ICD-10-kod F43.8A), är ett stressrelaterat tillstånd som uppstår till följd av bland annat långvarig exponering för hög arbetsbelastning utan tillräcklig återhämtning. Yoga diskuteras inom forskning som en potentiell intervention för att minska faktorer, såsom långvarig arbetsrelaterad stress och sömnsvårigheter, vilka på sikt kan leda ti

Bakgrund: Rektusdiastas är vanligt förekommande hos gravida kvinnor och är muskeldelning mellan musculus rectus abdominis två muskelbukar. Delningens svårighetsgrad är varierande och det skiljer sig mellan olika länder hur stor den måste vara för att klassificeras som rektusdiastas. I dagsläget finns det begränsad forskning på interventioner för att förebygga och behandla tillståndet. Syfte: Syft

Recent years witnessed mass migration towards Europe, from Russia's 2022 invasion of Ukraine and the 2015 Migrant Crisis linked to war in Syria. This article explores UK government discussion around these two significant crises, focussing on the challenges they present and the portrayal of refugees. It asks how far ministers' language differentiated between Ukrainians and Syrians regarding welfare

The unicellular eukaryote Saccharomyces cerevisiae is an invaluable resource for the study of basic eukaryotic cellular and molecular processes. However, its small size compared to other eukaryotic organisms the study of subcellular structures is challenging. Expansion microscopy (ExM) holds great potential to study the intracellular architecture of yeast, especially when paired with pan-labelling

Base excision repair is the dominant DNA repair pathway of chemical modifications such as deamination, oxidation, or alkylation of DNA bases, which endanger genome integrity due to their high mutagenic potential. Detection and excision of these base lesions is achieved by DNA glycosylases. To investigate the remarkably high efficiency in target site search and recognition by these enzymes, we appl

Store-operated Ca2+ entry (SOCE) is the major route of Ca2+ influx in platelets. The Ca2+ sensor stromal interaction molecule 1 (STIM1) triggers SOCE by forming punctate structures with the Ca2+ channel Orai1 and the inositol trisphosphate receptor (IP3R), thereby linking the endo-/sarcoplasmic reticulum to the plasma membrane. Here, we identified the BAR domain superfamily member bridging integra

The G-protein-coupled receptor (GPCR) superfamily mediates cellular responses and communication across cellular membranes and is the largest known class of molecular targets with proven therapeutic value. For probing conformational changes of GPCRs and others in a live cell setting, fluorescence resonance energy transfer (FRET) is usually the method of choice. FRET probes often require careful lab

Risk factors for developing bloodstream infections (BSIs) caused by Aerococcus bacteria remain insufficiently examined. In this nationwide case–control study in Sweden, 19 of 23 clinical microbiological laboratories identified patients who had aerococcal BSIs during 2012–2016. We compared each of those index patients with 4 controls matched for age, sex, and county of residence. Overall, 588 episo

Understanding the structure of supramolecular complexes provides insight into their functional capabilities and how they can be modulated in the context of disease. Super-resolution microscopy (SRM) excels in performing this task by resolving ultrastructural details at the nanoscale with molecular specificity. However, technical limitations, such as underlabelling, preclude its ability to provide

In the vicinity of metallic nanostructures, absorption and emission rates of optical emitters can be modulated by several orders of magnitude1,2. Control of such near-field light-matter interaction is essential for applications in biosensing3, light harvesting4 and quantum communication5,6 and requires precise mapping of optical near-field interactions, for which single-emitter probes are promisin

Interrogating platelets and their densely packed, highly abundant receptor landscape is key to understand platelet clotting, a process that can save lives when stopping blood loss after an injury, but also kill when causing heart attack, stroke, or pulmonary embolism. The underlying key receptor distributions and interactions, in particular the relevance of integrin clustering, are not fully under

Single-molecule localization microscopy (SMLM) aims for maximized precision and a high signal-to-noise ratio1. Both features can be provided by placing the emitter in front of a metal-dielectric nanocoating that acts as a tuned mirror2-4. Here, we demonstrate that a higher photon yield at a lower background on biocompatible metal-dielectric nanocoatings substantially improves SMLM performance and

DNMT3A/3L heterotetramers contain two active centers binding CpG sites at 12 bp distance, however their interaction with DNA not containing this feature is unclear. Using randomized substrates, we observed preferential co-methylation of CpG sites with 6, 9 and 12 bp spacing by DNMT3A and DNMT3A/3L. Co-methylation was favored by AT bases between the 12 bp spaced CpG sites consistent with their incr

Fluorescence microscopy allows specific and selective imaging of biological samples. Unfortunately, unspecific background due to auto-fluorescence, scattering, and non-ideal labeling efficiency often adversely affect imaging. Surface plasmon-coupled emission (SPCE) is known to selectively mediate fluorescence that spatially originates from regions close to the metal interface. However, SPCE combin

The maker movement has reached the optics labs, empowering researchers to create and modify microscope designs and imaging accessories. 3D printing has a disruptive impact on the field, improving accessibility to fabrication technologies in additive manufacturing. This approach is particularly useful for rapid, low-cost prototyping, allowing unprecedented levels of productivity and accessibility.

We propose symmetrical cationic trimethine cyanine dyes with β-substituents in the polymethine chain based on modified benzothiazole and benzoxazole heterocycles as probes for the detection and visualization of live and fixed cells by fluorescence microscopy. The spectral-luminescent properties of trimethine cyanines have been characterized for free dyes and in the presence of nucleic acids (NA) a

In 2025, the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) at the National Institutes of Health celebrates 75 years of leadership in diabetes research. The NIDDK serves people of the U.S. affected by or at risk for many chronic diseases, including diabetes and other endocrine, metabolic, and digestive disorders, by funding innovative research to develop better treatment

Vegetation is the major source of volatile organic compounds (VOCs) in the atmosphere, which affect both air quality and climate. Long-term ecosystem-level data on biogenic VOC (BVOC) emissions, however, are limited. This is especially true regarding the impacts of landscape-scale disturbances like clear-cutting on the short-term and longer seasonal-scale emissions of boreal forests, particularly
