Chemical exchange saturation transfer (CEST) magnetic resonance imaging (MRI) has emerged as a powerful imaging technique sensitive to tissue molecular composition, pH, and metabolic processes in situ. CEST MRI uniquely probes the physical exchange of protons between water and specific molecules within tissues, providing a window into physiological phenomena that remain invisible to standard MRI.
Finding direct records of the ancient Earth's atmosphere is key to understand the evolution of the entire planet. Nevertheless, such records are scarce, and only a few geological samples with preserved paleo-atmospheric signatures are available today. In this study, we analyzed noble gases contained in shocked granitic and volcanic rocks collected across the 380 Ma-old Siljan impact structure (in
Introduction Management of testicular torsion varies between specialties resulting in lack of standardization. The aim of this survey was to assess pre-, peri-, and postoperative differences. Methods An online questionnaire was distributed in 2023 to general and pediatric surgeons, pediatric urologists, and urologists by the Trainees of European Pediatric Surgery. Main Results Among 88 respondents
In the CONVINCE trial, the primary analysis demonstrated a survival benefit for patients receiving high-dose hemodiafiltration (HDF) as compared with high-flux hemodialysis (HD). A secondary objective was to evaluate effects on health-related quality of life (HRQoL); assessed in eight domains (physical function, cognitive function, fatigue, sleep disturbance, anxiety, depression, pain interference
Organophosphate hydrolases are proficient catalysts of the breakdown of neurotoxic organophosphates and have great potential as both biotherapeutics for treating acute organophosphate toxicity and as bioremediation agents. However, proficient organophosphatases such as serum paraoxonase 1 (PON1) and the organophosphate-hydrolyzing lactonase SsoPox are unable to hydrolyze bulkyorganophosphates with
How colour polymorphisms are maintained in natural populations constitutes a key subject of study for evolutionary ecologists. One of the mechanisms that has been put forward to explain this phenomenon is negative frequency-dependent selection, which can be caused by different mechanisms. Among these mechanisms is mate choice, or the selection as a potential mate of the rare or dissimilar colour m
Background: Emerging evidence suggests that artificial intelligence (AI) can increase cancer detection in mammography screening while reducing screen-reading workload, but further understanding of the clinical impact is needed. Methods: In this randomised, controlled, parallel-group, non-inferiority, single-blinded, screening-accuracy study, done within the Swedish national screening programme, wo
For more than a century, the dairy industry has used high-pressure homogenization for size reduction of fat globules. The prevailing break-up mechanism, turbulence, has been thoroughly investigated and the equipment continuously optimized thereafter. However, the high-pressure homogenizer is also used in size reduction of plant cell structures, for example in production lines of plant-based bevera
Raw sediment samples which are without prior lengthy laboratory preparation can be used to obtain a rough but rapid estimate of the luminescence equivalent dose, and thus of the relative age of the sediment. In this study, we tested this range-finder method on clastic sediments in NE Poland for the first time, with special focus on Pleistocene meltwater sediments generated by highly energetic glac
The field of organ transplantation is experiencing a transformative shift with the rise of Advanced Therapy Medicinal Products (ATMPs), which include gene therapies, somatic cell therapies, and tissue-engineered products. These therapies offer new, potentially curative treatments for longstanding medical challenges, impacting numerous patients. However, their adoption is hindered by complex regula
Background: Butaro Cancer Center of Excellence (BCCOE) was founded to serve Rwanda’s rural low-income population, providing subsidized cancer diagnosis and treatment with transport stipends for the lowest-income patients. We examined whether travel distance to BCCOE was associated with advanced-stage diagnoses and treatment completion. Methods: We conducted a retrospective cohort study using medic
The coefficient of friction (COF) and wear are critical parameters in assessing disc brake performance. However, their study is challenging due to their interdependence on contact pressure, sliding velocity, temperature, and material composition. The complex contact interactions between brake pads and discs involve the continuous formation and destruction of mesoscopic contact plateaus, which
In the present work, we describe the design, synthesis, and evaluation of a galectin-8- binding fluorescent probe designed for a competitive fluorescence polarization (FP) assay for screening new galectin-8N inhibitors. The probe was characterized for its photophysical properties and its binding affinity for galectin-8N was determined by using FP. We evaluated the probe in a competitive FP assay w
Introduction: Patients with substantial comorbidity burden are underrepresented in clinical trials on endovascular thrombectomy (EVT), despite being common in clinical routine care. Therefore, analysis of observational data is needed to evaluate how increasing comorbidity burden affects procedural success rate, complication rate, and clinical outcome following EVT. Patients and methods: We conduct
External quality assessment (EQA) schemes for pathology are essential, yet large/international programmes do not assess morphology-based biomarkers or address local/regional needs. This study outlines bottom-up initiated, flexible Swedish Digital Pathology EQA rounds for breast pathology, and presents results from the 2021 and 2023 rounds. Six breast carcinoma cases were selected for each EQA roun
Older adults are often portrayed as unwilling or unable to address quality issues in the formal care they receive. This study explores a methodology that captures the everyday reactions of older care users to quality problems, offering a nuanced understanding of their voice and agency when dissatisfied with care services. Using a telephone diary method, eight care users were contacted twice a week
A broad discussion of the ground-state potential-energy surfaces of doubly even deformed and transitional nuclei with Z = 50-82 is presented. The surfaces are calculated microscopically as functions of the quadrupole axial ε and non-axial γ and the axial hexadecapole ε4 deformations. A correlation between the form of the surfaces and the experimental spectroscopic trends is extensively discussed.
Purpose: Prolonged stress leading to sick leave is a serious health problem, and it is crucial to find ways to support recovery. The aim of this review was to synthesize the results from qualitative research about what people with stress-related disorders experience as supportive for recovery. Methods: The systematic review was designed as a qualitative meta-synthesis following the recommendations
Monitoring toxic elements has a long tradition in Slovenia due to historical mining. More recently, attention has shifted to essential elements, since both deficiencies and excesses can harm health. Regular monitoring of (non-)essential elements supports risk assessment and policymaking. While urine and blood are common biomonitoring matrices, hair offers a non-invasive alternative that reflects e
