Stone heart (ischemic contracture) is a rare and serious condition observed in the heart after periods of warm ischemia. The underlying mechanisms are largely unknown and treatment options are lacking. In view of the possibilities for cardiac donation after circulatory death (DCD), introducing risks for ischemic damage, we have investigated stone heart in pigs. Following cessation of ventilation,
Shuker points to some inconsistencies in my terminology about consequence laws in evolutionary biology, specifically that gene flow and recombination are not as easily classified as one gets the impression of after reading Sober (1984). I agree, and I also emphasize that evolutionary biology should not only focus on consequence laws, but also source laws arising from the ecological selective envir
Background:Sensory overresponsivity (SOR) has emerged as a potential endophenotype in obsessive-compulsive disorder (OCD), but few studies have examined SOR in relation to the major symptom dimensions of OCD and to symptoms across the full obsessive-compulsive (OC) symptom spectrum.Objective:This study had 2 main objectives. First, we examined the psychometric properties of the SOR Scales in a com
Slow conformational changes are often directly linked to protein function. It is however less clear how such processes may perturb the overall folding stability of a protein. We previously found that the stabilizing double mutant L49I/I57V in the small protein chymotrypsin inhibitor 2 from barley led to distributed increased nanosecond and faster dynamics. Here we asked what effects the L49I and I
Many science students struggle with using scientific language and making sense of scientific phenomena. Thus, there is an increased interest in science education research and public policy with regard to understanding and promoting scientific language use and sensemaking in science classrooms. However, there is a lack of comparative studies on how upper-secondary school students of different achie
Ventricular-arterial coupling (VAC) has independent diagnostic and prognostic value for cardiovascular (CV) risk stratification, but studies on its association with anthropometric and CV factors are sparse in young individuals without overt CV disease. We aim to provide descriptive data regarding VAC and its associations with CV risk factors in young adults without overt CV disease. For 631 (mean
In this article, we read the COVID-19 pandemic from a Lacanian perspective, in which trauma and ontological insecurity are at the heart of the analysis. Using a psychoanalytical approach allows us to grasp why the most common response to the pandemic consisted of intensified commitments to home, nationalism, and exclusionary bordering practices and, in effect, a return to geopolitical notions of “
The performance of timber in exposed environments is affected by several biotic and abiotic factors. For timber cladding and decking, two important aspects include reduced structural performance due to fungal decay and aesthetical changes resulting from superficial effects such as photodegradation and moulds. Predicting the long-term performance of timber is important because it enables rational m
Gender differences in achievement exhibit variation between domains and between countries. Much prior research has examined whether this variation could be due to variation in gender equality in opportunities, with mixed results. Here we focus instead on the role of a society's values about gender equality, which may have a more pervasive influence. We pooled all available country measures on adol
Little is known about how community composition in the plant microbiome is affected by events in the life of a plant. For example, when the plant is exposed to soil, microbial communities may be an important factor in root community assembly. We conducted two experiments asking whether the composition of the root microbiota in mature plants could be determined by either the timing of root exposure
Animals live in dynamic worlds where they use sensorimotor circuits to rapidly process information and drive behaviours. For example, dragonflies are aerial predators that react to movements of prey within tens of milliseconds. These pursuits are likely controlled by identified neurons in the dragonfly, which have well-characterized physiological responses to moving targets. Predominantly, neural
It is widely known that nanoparticle seeded growth of III-V semiconductor nanowires often occurs via the vapor-liquid-solid mechanism. However, conventional growth of nanowires is carried out in closed systems, where mostof the details and dynamics of the growth are impossible to follow. Since all analysis is typically carried out after growth completion and transfer, only the trends in the produc
Radiocarbon dating provides a key chronological framework for studying past environmental changes. Raw radiocarbon ages measured in samples must be converted to calendar ages using an appropriate calibration curve. Tree-ring datasets provide the gold-standard for developing a precise curve of atmospheric radiocarbon levels over long-time scales. Here, we reconstruct atmospheric radiocarbon levels
In the late 1970s, the Swedish economy faced a profit squeeze which threatened to hamper investments and hence the creation of jobs. This engendered a massive debate in the media and among economists and policymakers. This paper investigates the discussion of “the politics of profits”, the policy measures directed towards manipulating the distribution between capital income and labour income in th
