Challenges to estimating and managing risks with hexavalent chromium exposure : A mixed-methods study of Swedish workplaces

Using a mixed-methods approach, we assessed understanding of risks from exposure to the non-threshold carcinogen hexavalent chromium (Cr(VI)) among workers (n = 113) and occupational health and safety managers (n = 13) at 14 worksites with potential exposure to Cr(VI). We found that 55% of the workers had a measurable concentration of inhalable Cr(VI), with 19% exceeding 1 µg/m3, a level that corr

Correlations Between Colloidal Stability and Peroxidase Activity of Prussian Blue Nanozymes in Salt Solutions

Prussian blue (PB) nanozymes have emerged as durable enzyme-mimicking catalysts with broad applications across many fields. Practical uses often involve exposure to salinity that influences their colloidal and catalytic behaviors, yet the specific effects of ions on PB particles are underexplored. This study investigates how electrolyte type and concentration affect the colloidal stability and enz

Modulation of pTau181 by Glypican-1-Derived Heparan Sulfate in Human Neural Progenitor Cells and ApoE4-Expressing Induced Neurons

In Alzheimer's disease (AD) there is accumulation of amyloid-β (Aβ) and hyperphosphorylated tau (pTau) in the brain. Aβ activates kinases that phosphorylate tau. Increased pTau181 is a signal for hyperphosphorylation of tau. The generation of Aβ from amyloid precursor protein (APP) and the release of heparan sulfate (HS) from the proteoglycan glypican-1 (GPC1) are interconnected. Release of HS is

Real-world outcomes with ibrutinib in relapsed or refractory mantle cell lymphoma : a Danish population-based study

Ibrutinib was approved for relapsed/refractory (R/R) mantle cell lymphoma (MCL) based on high response rates in clinical trials, but it is unclear how effective ibrutinib is in the real-world setting. This study provides population-based response rates and survival estimates and characterization of prognostic indicators and adverse events (AEs) to ibrutinib for patients with R/R MCL. All patients

International elite Para athletes' perspectives on anti-doping: what works, what doesn't and what's next?

Objectives Para athletes may face unique challenges in the anti-doping system, including issues of privacy, implementation, comprehension and accessibility. While previous studies have examined non-disabled athletes’ views, little is known about how international elite Para athletes perceive anti-doping procedures. The aim of this study was to increase the understanding of elite Para athletes’ exp

Large and Increasing Biospheric Productivity of Northern Ecosystems

Plants take up carbon dioxide (CO2) through photosynthesis. How this will change with rising CO2 concentrations in the atmosphere will strongly determine future climate change. An increase in the seasonal variations of atmospheric CO2 in recent decades indicates a positive trend in photosynthetic carbon uptake. We combined data-driven seasonal cycles of plant productivity with carbon sinks across

Phenotyping Exertional Breathlessness Using Cardiopulmonary Cycle Exercise Testing in People With Chronic Airflow Limitation

Background: Exertional breathlessness is a cardinal symptom of people with chronic airflow limitation (CAL) and can be evaluated using cardiopulmonary exercise testing (CPET). Research Question: Does abnormally high exertional breathlessness in relationship to the rate of oxygen uptake (V′O2) and minute ventilation (V′E) indicate different underlying pathophysiologic mechanisms and clinical charac

Plasma C4d levels correlate with treatment response and renal activity in proliferative lupus nephritis

Objective The investigation of complement factors in lupus nephritis (LN) in relation to treatment response and the impact of underlying genetics of C4. Methods Seventy-seven patients with active LN confirmed by a kidney biopsy and in whom second biopsies had been performed after immunosuppressive treatment were included. Complement factors C3, C4, C4d and C4d/C4 ratio were evaluated at the biopsy

Treatment limitations and participation in elderly patients – the gap between medical-ethical guidelines and clinical practice : a cross sectional-study from Sweden

Background: Decision-making regarding treatment limitations such as “Do not attempt resuscitation” (DNAR) orders for older patients has been found deficient. Patients ≥ 80 years with substantial comorbidity have little chance of surviving cardiac arrest, thus require thorough risk classification focusing on comorbidity and frailty. This study aimed to explore the degree of frailty, comorbidity and

Hyperspectral retinal imaging to detect Alzheimer’s disease in a memory clinic setting

Background: Previous literature indicate retinal hyperspectral imaging as a non-invasive method with the potential for identifying amyloid-beta (Aβ) protein deposits. Current diagnostic methods, such as cerebrospinal fluid analysis or positron emission tomography, are costly, invasive, and non-scalable. Hyperspectral imaging offers a potentially accessible alternative for early detection of Alzhei

Genome-wide identification of quantitative trait nucleotides for plant architecture-related traits in peanut

Peanut (Arachis hypogaea L.) is globally recognized as an important oilseed crop. Traits related to plant architecture are closely associated with yield in peanut. In this study, we focused on four specific traits related to plant architecture—first branch length (FBL), main stem height (MSH), stem diameter (SD), and the number of nodes on the main stem (NSK)—across three locations. Using whole-ge

YAP/TAZ deletion in vascular smooth muscle cells mirrors atherosclerosis-associated transcriptional programs

The transcriptional co-activators YAP (YAP1) and TAZ (WWTR1) are central regulators of vascular smooth muscle cell (VSMC) phenotype and vascular homeostasis. This study investigates the consequences of VSMC-specific YAP/TAZ deletion and its relevance to atherosclerosis. Using bulk and single-cell RNA sequencing data, we demonstrate that gene expression changes following two (2-week YT) and eight w

Routinely collected health data on 10-year genitourinary and gastrointestinal morbidity after ultra-hypofractionated versus conventionally fractionated radiotherapy for localised prostate cancer in the randomised, non-inferiority, phase 3 trial HYPO-RT-PC

Background and purposeHYPO-RT-PC was the first phase 3 trial showing the long-term efficacy and safety of extremely hypofractionated radiotherapy schedules (ultra-hypofractionation or stereotactic body radiotherapy) compared with standard radiotherapy in localised prostate cancer. We aimed to verify their safety in the context of a clinical trial, by comparing events of potentially radiotherapy-re

Network-based insights into miRNA regulation of β-cell insulin secretion in type 2 diabetes

Increasing evidence suggests that microRNAs (miRNAs) contribute to pancreatic β-cell compensation during type 2 diabetes (T2D) pathogenesis. To examine miRNA-mRNA interactions in human islets and their roles in β-cell insulin secretion and T2D, we performed small-RNA sequencing on pancreatic islets from nine individuals with T2D and 52 non-diabetic controls. We identified 70 differentially express

The relationship in women between genetic liability and the risk of onset of alcohol use disorder while pregnant or rearing an infant, toddler, or preschool child

While pregnancy clearly reduces the risk for Alcohol Use Disorder (AUD) onset, we know less about the impact on AUD risk of having young children and how these effects vary across maternal age and level of maternal AUD genetic risk. Therefore, in 1.2 million parous Swedish women born 1960-1995, we examined those with a first registration for AUD between ages 15-40 while first pregnant, or while ra

Effects on Serum Protein Levels From One Bout of High Intensity Interval Training in Individuals With Axial Spondyloarthritis and Controls

BACKGROUND: Axial spondyloarthritis (axSpA) is a chronic inflammatory disease primarily affecting the axial skeleton causing pain, inflammation, and stiffness. Individuals with axSpA are at greater risk of developing cardiovascular disease, which can be counteracted by physical activity. High-intensity interval training (HIIT) has been shown to improve cardiovascular health, but the effect on dise
