Di-isobutylene has received significant attention as a promising fuel blendstock, as it can be synthesized via biological routes and is a short-listed molecule from the Co-Optima initiative. Di-isobutylene is also popularly used as an alkene representative in multi-component surrogate models for engine studies of gasoline fuels. However, there is limited experimental data available in the literatu
OBJECTIVE:Recent advances in AI-based Large Language Models (LLM) can transform individuals’ descriptions of emotional health into numeric representations that predict rating scales with an accuracy approaching theoretical upper limits. This advancement enables examing various open-ended response formats. We develop and evaluate formats ranging from closed to more open: 1) selecting descriptive wo
Background: Propionic acid fermentation from renewable feedstock suffers from low volumetric productivity and final product concentration, which limits the industrial feasibility of the microbial route. High cell density fermentation techniques overcome these limitations. Here, propionic acid (PA) production from glucose and a crude glycerol/glucose mixture was evaluated using Acidipropionibacteri
Objectives: Thermal and mechanical stresses during osteotomy preparation can impair implant osseointegration. This study investigated implant osseointegration following the measurement of temperature exposure during osteotomy drilling, varying drill design, sequence, and drill wear. Materials and methods: 36 tapered implants were placed in a mandibular minipig model after guided drilling of implan
Introduction: Data on outcome in persons with haemophilia B (PwHB) are limited and mainly extrapolated from studies of haemophilia A (HA). Aim: To characterize treatment outcomes in persons with severe HB in the Nordic region, with a focus on joint health, compared with matched controls with HA. Methods: PwHB attending haemophilia centres in Denmark, Finland, Norway and Sweden were enrolled and ma
Background The lungs are the second most common site of metastases in colorectal cancer (CRC). The aim of this study was to investigate prognostic factors, including RNA‐binding motif protein 3 (RBM3) expression, in patients with CRC treated with pulmonary metastasectomy (PM). Methods The cohort included all patients treated with PM at Skåne University Hospital, Lund, Sweden, from 2000 to 2014. C
Image-based analysis of breast tumour growth rate may help optimize breast cancer screening and diagnosis. It may improve the identification of aggressive tumours and suggest optimal screening intervals. Virtual clinical trial (VCT) is a simulation-based method used to evaluate and optimize medical imaging systems and design clinical trials. Our work is motivated by desire to simulate multiple scr
Mantle cell lymphoma (MCL) is a B-cell malignancy currently considered incurable. Although some patients obtain prolonged remission after first-line chemoimmunotherapy, many will need several treatment lines. Here, we present a nationwide assessment of treatment strategies, time to progression and survival in MCL. All patients diagnosed with MCL 2006-2018 were identified in the Swedish Lymphoma Re
BACKGROUND: Very preterm infants often require respiratory support and are therefore exposed to an increased risk of chronic lung disease and later neurodevelopmental disability. Although methylxanthines are widely used to prevent and treat apnea associated with prematurity and to facilitate extubation, there is uncertainty about the benefits and harms of different types of methylxanthines.OBJECTI
Background: Snacking is a common diet behaviour which accounts for a large proportion of daily energy intake, making it a key determinant of diet quality. However, the relationship between snacking frequency, quality and timing with cardiometabolic health remains unclear. Design: Demography, diet, health (fasting and postprandial cardiometabolic blood and anthropometrics markers) and stool metagen
OBJECTIVE: Digital self-management programs are increasingly used in the management of osteoarthritis (OA). Little is known about heterogeneous patterns in response to these programs. We describe weekly pain trajectories of people with knee or hip OA over up to 52-week participation in a digital self-management program.METHODS: Observational cohort study among participants enrolled between January
For millennia, agriculture has been shaping landscapes on Earth. Technological change has increased agricultural productivity dramatically, especially in the past six decades, but also resulted in trade-offs such as land and soil degradation, emission of greenhouse gases (GHGs), and spreading of toxic substances. In this article we review the impacts of agriculture on the world’s arable land. We s
OBJECTIVE: To investigate changes in socioeconomic inequalities in patient-related outcomes and pain medication use, following participation in a digital self-management intervention for osteoarthritis (OA) in Sweden.METHOD: Participants with hip/knee OA enrolled in the digital intervention were included. Self-reported outcomes collected were the numerical rating scale (NRS) pain, activity impairm
The Colombian peace agreement, which has brought an end to a prolonged internal armed conflict has led to significant land use changes that underscore existing inequalities and struggles over natural resources. The expansion of industries such as cattle ranching, agriculture, and extraction is encroaching on indigenous territories and protected areas, resulting in negative consequences for communi
The serum concentration of YKL-40, a matrix protein of specific granules in neutrophils, was determined by RIA in 90 patients hospitalized with pneumonia of suspected bacterial origin. Of these, 64 were followed prospectively during antibiotic treatment with blood samples taken on day 0 (on admission and the start of treatment) and on days 1, 3, 5, 7, 10, and 21. Serum YKL-40 at admission was incr
Droughts are often suspected to increase the risk of violent conflict through agricultural production shocks, and existing studies often explore these links through meteorological proxies. In Syria, an alleged agricultural collapse caused by drought is assumed to have contributed to increased migration and the conflict outbreak in 2011. Here we use satellite derived cropland and climate data to st
Background: Ultra-high field magnetic resonance imaging (MR) may be used to improve intracranial blood flow measurements. However, standard cardiac synchronization methods tend to fail at ultra-high field MR. Therefore, this study aims to investigate an alternative synchronization technique using Doppler ultrasound. Methods: Healthy subjects (n = 9) were examined with 7T MR. Flow was measured in t
Background and Purpose - Aortic valve stenosis may lead to atrial and ventricular remodeling, predisposes to atrial fibrillation, and may also be an independent risk factor of ischemic stroke. However, information on stroke rates among persons with aortic valve stenosis are sparse. We aimed to determine the incidence rates and relative risks of ischemic stroke in individuals with diagnosed aortic
Summary: In this population-based study, we compared the incidence of distal radius fracture in 2016 with that in the same region’s adult general population in 2001 using radiographs to identify fracture cases. We showed that the incidence decreased by 24% in 2016 compared with 2001 indicating an important development. Introduction: We conducted an epidemiological study on residents of northeaster
Traditional treatments, including a variety of thermal therapies have been known since ancient times to provide relief from rheumatoid arthritis (RA) symptoms. However, a general absence of information on how heating affects molecular or immunological targets relevant to RA has limited heat treatment (HT) to the category of treatments known as "alternative therapies". In this study, we evaluated t
