Modelling carbon uptake in Nordic forest landscapes using remote sensing

Boreal forests and peatlands store over 30% of the global terrestrial carbon in their vegetation and soil. but changing climate can compromise the current carbon stock. Rising air temperatures, changing precipitation patterns and increased risk of natural disturbances can impact the ability of the boreal ecosystems to absorb and store carbon, reducing their effectiveness as carbon sinks. Reliable

The Free Hormone Hypothesis: Is Free Serum25-Hydroxyvitamin D a Better Marker for Bone Mineral Density in Older Women?

It is presently unclear whether free serum 25 hydroxyvitamin D (S 25(OH)D) better reflects bone health than total S 25(OH)D. We have previously shown that summer total S 25(OH)D values are more useful to predict bone mineral density (BMD) than winter values. Our objective was therefore to compare the relative importance of free and total S 25(OH)D for BMD by season. BMD was measured by dual energy

Impaired blood pressure regulation in post-COVID-19 postural orthostatic tachycardia syndrome: novel disease mechanisms beyond sinus tachycardia

Background: Postural orthostatic tachycardia syndrome (POTS) is a prevalent cardiovascular disorder after COVID-19 infection. Although POTS is characterized by the presence of sinus tachycardia, other hemodynamic disturbances including blood pressure (BP) regulation, remain largely unexplored.Aims: We investigated BP changes using 24-hour ambulatory-BP-monitoring in patients with new-onset POTS af

Amphetamine use as a predictor of cardiovascular and cerebrovascular mortality and morbidity : a longitudinal cohort study of criminal justice clients

Introduction: Amphetamine use is an increasing problem, and studies suggest a connection between amphetamine use and cardiovascular and cerebrovascular pathology. However, few long-term studies examine amphetamine users' risk of cardiovascular and cerebrovascular pathology, in comparison to users of other drugs. In addition, in a criminal justice system, illicit drug use and psychiatric comorbidit

Ultra-processed food consumption, plasma metabolite profile, and risk of all-cause and cause-specific mortality in a population-based cohort

Background & aims: Epidemiological evidence on ultra-processed food (UPF) and cause-specific mortality remains limited and mixed. Molecular mechanisms underlying UPF intake and mortality remain unexplored. This study aimed to evaluate the associations between UPF consumption, metabolic signatures, and all-cause, premature, and cause-specific mortality. Methods: This study included 27670 partic

Prediction of adverse maternal and perinatal outcomes associated with pre-eclampsia and hypertensive disorders of pregnancy : a systematic review and meta-analysis

Background: Hypertensive disorders of pregnancy are a leading cause of maternal and perinatal morbidity and mortality. If women at high risk for developing complications could be identified early, level of care could be triaged, limited resources could be correctly allocated and targeted interventions to prevent complications could be implemented. Methods: We updated a systematic review and meta-a

The Physical Activity Health Paradox in Type 2 Diabetes

Introduction: The physical activity health paradox refers to the contrasting associations of leisure-time physical activity and occupational physical activity with cardiovascular disease, but whether this applies to Type 2 diabetes risk is unknown. This study aimed to investigate the physical activity health paradox and age-specific Type 2 diabetes. Methods: Working adults (N=5,866) in Denmark age

The interaction of human serum components with model membranes containing phospholipids and lipopolysaccharides

Lipoproteins, key mediators of lipid transport, facilitate the bidirectional transfer of lipids such as fatty acids, triglycerides, and cholesterol between soluble particles and cell membranes. High-density lipoproteins (HDL) primarily engage in reverse cholesterol transport, while low-density lipoproteins (LDL) predominantly deposit lipids, affecting cardiovascular health with a well-known role i

Exhaled breath particles as a diagnostic tool for bronchiolitis obliterans syndrome in lung transplant recipients: a longitudinal study

Background: Long-term survival after lung transplantation is significantly shorter compared with other solid organ transplantations. Chronic lung allograft dysfunction (CLAD), including bronchiolitis obliterans syndrome (BOS), remains the major barrier to survival. CLAD is diagnosed according to ISHLT's guidelines: a 20% drop in FEV1 using spirometry for CLAD grade 1. Given the difficulties of con

Endothelial Cell pY397-FAK Expression Predicts the Risk of Breast Cancer Recurrences after Radiotherapy in the SweBCG91-RT Cohort

Purpose: Identifying biomarkers of radiotherapy (RT) response is important for optimizing the treatment of early breast cancer. In this study, we tested the interaction between endothelial cell (EC) expression of phospho-Tyr397-FAK (pY397-FAK) and adjuvant-RT on clinical outcomes after breast-conserving surgery (BCS) within a randomized study. Preclinical data suggest an enhanced effect of RT on l

Profiling associations of interactive ligand-receptors (HLA class I and KIR gene products) with the progression to type 1 diabetes among seroconverted participants

AIMS/HYPOTHESIS: The aim of this work was to explore associations between type 1 diabetes progression from stages 1 or 2 to stage 3 and interacting ligand-receptor complexes of HLA class I (HLA-I) and KIR gene products.METHODS: Applying next-generation sequencing technology to genotype HLA-I genes (HLA-A, -B, -C) and KIR genes (KIR2DL1, KIR2DL2, KIR2DL3, KIR2DL4, KIR2DL5, KIR2DS1, KIR2DS2, KIR2DS3

Branched-Chain Amino Acid Supplementation Enhances Substrate Metabolism, Exercise Efficiency and Reduces Post-Exercise Fatigue in Active Young Males

Background: Branched-chain amino acids (BCAAs, isoleucine, leucine, and valine) are commonly applied to promote muscle protein synthesis. However, the effects of BCAAs on exercise-induced substrate metabolism, performance and post-exercise fatigue during endurance exercise remain unclear. Methods: In a double-blind cross-over design, eleven active males completed 1 h of constant load exercise (CLE

Age-Specific Diagnostic Panorama Among People With Intellectual Disabilities in Comparison With the General Population : A Longitudinal Register Study (IDcare)

BACKGROUND: People with intellectual disabilities (ID) are known to have a higher risk for a wide range of health conditions compared to the general population. However, there is little research comparing a more comprehensive range of diseases and conditions at different ages. Therefore, the aim of this study was to explore the overall age-specific diagnostic pattern among people with ID compared

Data-driven modelling of methane fluxes across a mire complex based on replicated eddy covariance measurements and spatially-resolved driver information

Northern mires are significant natural sources of atmospheric methane (CH4), yet estimating CH4 emissions remains challenging due to their complex spatio-temporal dynamics. While eddy covariance (EC) measurements provide valuable insights into ecosystem-scale CH4 fluxes (FCH4) over mire areas typically < 0.05 km², the predictability of FCH4 at the mesoscale (∼0.5 – 20 km²) of a mire complex based

Estimation of the Added Cancer Risk Derived From EVAR and CTA Follow-Up

Objective: The aim of this study was to assess the risk of radiation-induced cancer development in patients that have undergone an infrarenal EVAR, stratifying the relative contributions of the procedure and the preoperative and postoperative CTAs. Methods and Materials: The organ-specific absorbed radiation doses from CTA and the EVAR procedure were estimated from the radiation exposures of 95 an

Markers of inflammation predicts long-term mortality in patients with acute coronary syndrome – a cohort study

Background: Chronic low-grade inflammation is a well-known risk factor for coronary heart disease (CHD) and future cardiovascular events. Anti-inflammatory therapy can reduce the risk of ischemic cardiovascular disease (CVD) events following myocardial infarction (MI). However, it remains unknown to what extent inflammation at the time of an acute event predicts long-term outcomes. We explored whe

Deckarserien och avtalstolkning – Tolkning av upphovsrättsliga överlåtelse- och upplåtelseavtal i ljuset av NJA 2025 s. 162

Uppsatsen utgår från spänningen mellan en enhetlig avtalstolkningslära eller att låta branschspecifika omständigheter och principer styra avtalstolkning. Fokus ligger på upphovsrättsliga överlåtelse- och upplåtelseavtal, där specifikationsprincipen länge har förordat en restriktiv tolkning till upphovsmannens förmån, och där endast det som uttryckligen angetts i avtalet, ska anses ha överlåtits elThe thesis explores the tension between a unified doctrine of contract interpretation or an approach that allows sector-specific circumstances and principles to influence the interpretation of contracts. The primary focus of this analysis is on copyright transfer and licensing agreements, where the principle of specification has long supported a restrictive interpretation in the author’s interest,

Economic Impact of Severe Early-Onset Foetal Growth Restriction : A Multicentre Prospective Cohort Study

Objective: Foetal growth restriction (FGR) affects 10% of pregnancies, contributing to 30% of stillbirths. Current management of early-onset FGR (< 32 + 0 weeks' gestation) delivers the foetus before stillbirth or irreversible organ damage. The resulting preterm births create additional risks independent of FGR. We determined the economic cost associated with severe early-onset FGR. Design: Econom
