Purpose To evade immunosurveillance many cancers convert tryptophan (Trp) into kynurenine (Kyn), which induces immunotolerance and suppresses immune responses. Elevated Kyn amounts have been found in blood from patients with cutaneous melanoma. This study aimed to investigate whether higher Kyn abundance and lower Trp abundance can be detected on the surface of cutaneous melanoma lesions compared
Background Recent decades have witnessed tangible improvements in childhood cancer survival. However, the prognosis for children with congenital heart disease (CHD), the most prevalent birth defect, remains unclear. Due to improved survival of CHD and childhood cancer, evaluating outcomes within this intersection is important for clinical practice. We aimed to assess mortality post-cancer diagnosi
Ensuring functional safety is crucial for the deployment of autonomous systems in real-life dynamic environments, as they must operate reliably and safely among humans. However, existing safety systems are designed with a closed-world assumption and can over-constrain the system by shutting down the robot at every safety violation, limiting the robot’s ability to complete its tasks. To address thi
Populations are presumed to be adapted to local environmental conditions via natural selection, with gene flow breaking up local adaptations. In birds, various aspects of feathers may reflect local adaptation. For example, the insulation capacity of feathers could be greater in colder regions, while colour variation may also play a role in adapting to local environmental conditions since darker fe
Background: Associations between high physical activity (PA) levels and incident atrial fibrillation (AF) is found in some earlier studies. We aim to study the association between levels of PA and AF in two cohorts. Methods: We used data from the Uppsala Longitudinal Study of Adult Men (ULSAM) study, initiated in 1970, included men aged 50 years, with 2202 included in the study. Examinations were
Marketing and consumer research predominantly conceptualize inclusion and exclusion as dichotomous or merely coexisting, leaving their relationship undertheorized. This paper explores their dialectical interplay in market interactions through the experiences of migrant consumers. Drawing on Relational Dialectics Theory, we employ a contrapuntal methodological approach that integrates a semantic ne
Several African countries, mainly the Democratic Republic of Congo, Burundi, and Uganda, are facing highly transmissible mpox clade Ib epidemics, prompting the World Health Organization to declare a Public Health Emergency of International Concern. It has spread to key travel hubs like Kinshasa, Bujumbura, and Kampala, increasing international spread risks. Current mitigation efforts focus mainly
The identification of biomarkers predicting the burden of brain alpha-synuclein (α-syn) pathology in vivo represents a research priority in Lewy body disease (LBD). Recently, some kinetic parameters of seed amplification assays (SAAs) for α-syn showed associations with measures of clinical progression. However, preanalytical and analytical factors significantly affect these parameters, reducing re
Introduction: Food systems strongly influence both human and planetary health. Unhealthy diets aremajor risk factors for chronic disease and mortality, while food production contributes substantially togreenhouse gas emissions (GHGE), and other negative environmental impacts. Adopting moresustainable dietary patterns, such as the EAT-Lancet diet, has been proposed as part of the solution, butuncer
In June 2024, the community of Roxborough Park, Colorado conducted a wildfire evacuation exercise (or drill for short) that was observed by a team of researchers. This collaborative effort involved residents, community organizers, first responders, emergency managers, and researchers. The drill aimed to test and refine evacuation protocols, communication strategies, and coordination among various
In this note, we prove equicontinuity for the family of one-point densities with respect to a two-dimensional Coulomb gas at an inverse temperature β ≥ 1=2 confined by an external potential of Hele-Shaw (or quasi-harmonic) type. As a consequence, subsequential limiting Lipschitz continuous densities are defined on the microscopic scale. There are several additional results, for example comparing t
Aims/Hypothesis: Charcot foot (CF), a potentially debilitating complication of neuropathy, requires offloading to avoid foot deformities. Follow-up MRI examinations are often used to determine the optimal duration of total contact cast (TCC) offloading treatment. This study investigated the use of follow-up MRI during CF treatment and its relationship to offloading duration and risk of future surg
Dual-fuel engines are a way of transitioning the marine sector to carbon-neutral fuels like hydrogen and methanol. For the development of these engines, accurate simulation of the combustion process is needed, for which calculating the pilot’s ignition delay is essential. The present work investigates novel methodologies for calculating this. This involves the use of chemical kinetic schemes to co
Surface-confined synthesis provides alternative reaction pathways to those utilized within solution-phase chemistry and offers a route to extended molecular architectures with nanoscale dimensions and fascinating magnetic, electronic, and catalytic properties. However, these reaction pathways can be complex multistep processes, containing multiple reactive intermediates. Optimizing the selectivity
