Melanin-based color polymorphism is predicted to evolve and maintain through differential fitness of morphs in different environments, and several empirical studies indicate that life history strategies, physiology, and behavior vary among color morphs. Sex allocation theory predicts that parents should adjust their sex allocation based on differential costs of raising sons and daughters, and ther
The processes that govern human haematopoietic stem cell (HSC) self-renewal and engraftment are poorly understood and challenging to recapitulate in culture to reliably expand functional HSCs1–3. Here we identify MYC target 1 (MYCT1; also known as MTLC) as a crucial human HSC regulator that moderates endocytosis and environmental sensing in HSCs. MYCT1 is selectively expressed in undifferentiated
The sharing of human neuroimaging data has great potential to accelerate the development of imaging biomarkers in neurological and psychiatric disorders; however, major obstacles remain in terms of how and why to share data in the Open Science context. In this Health Policy by the European Cluster for Imaging Biomarkers, we outline the current main opportunities and challenges based on the results
Viral infections, including those caused by COVID-19, can produce striking morphologic changes in peripheral blood. Distinguishing between reactive changes and abnormal morphology of monocytes remains particularly difficult, with low consensus rates reported amongst hematopathologists. Here, we report a patient who developed transient monocytosis of 11.06 × 109/L with 32% promonocytes and 1% blast
Background: This study compared the 5-year outcomes of isolated proximal femoral varus osteotomy (FO) and combined proximal femoral varus and pelvic osteotomy (FPO) for the treatment of hip displacement in children with cerebral palsy (CP) in Sweden, focusing on the number of reoperations and residual hip displacement. Methods: The study included 163 children with a 5-year follow-up after FO or FP
Smallholder farmers are widely touted as essential to sustainable agricultural development in sub-Saharan Africa and beyond. But what exactly is meant by sustainable development, and how are smallholder farmers expected to contribute to it? In this perspective, we describe and assess two competing visions of sustainable development, namely Capital Theory and the Capabilities approach, paying speci
Agriculture is key to sustainable development globally – particularly incountries where agriculture both accounts for most of the land use andprovides a livelihood for most of the population. We map out a collaborativeresearch agenda aimed at tackling the urgent but poorly understood issue ofthe role of farmer organisations in overcoming political barriers tosustainable and inclusive agricultural
This pilot-scale study investigates the possibility of using nanofiltration after ultrafiltration to improve lignin recovery from kraft black liquor in a pulp mill. The nanofiltration step can increase overall lignin recovery and provide a clean permeate that could be used in the smelt dissolving tank to produce green liquor. Nanofiltration of kraft black liquor ultrafiltration permeate was perfor
Förlust av biologisk mångfald är ett av de största hoten mot ekosystem och derasfunktioner. Nästan 500 arter i den marina miljön i Sverige anses idag vara hotade ellersårbara. En av dessa är Sveriges enda val, tumlaren (Phocoena phocoena), som lever längs hela Sveriges kust och rör sig över stora områden i sin jakt på fisk att äta. Mänsklig påverkan, framför allt genom oavsiktliga bifångster vid gThe harbour porpoise (Phocoena phocoena) is a small toothed whale with a mainly coastal distribution in the northern hemisphere. As a marine top predator, the species can act as an indicator for early warning signs of ecosystem changes. At the same time, harbour porpoises are globally threatened by human activities and in need of conservation. Successful protection of harbour porpoises requires un
The Amsterdam 2022 International Consensus Statement on Concussion in Sport (6th International Conference on Concussion in Sport) was the first Concussion in Sport Group (CISG) consensus to consider the para athlete.1 To date, a lack of research in para sport on most aspects of concussion has prevented the development of evidence-informed consensus on any aspects of concussion care for para athlet
This article investigates how things given to local temples generate material, karmic, and emotional excess in contemporary Japan. What, how, and why people “store” at local Buddhist temple tell a story of a community and how people’s individual material histories become matters of communal concern and local heritage-making practices. While walking a fine line between memory and decommissioning of
BackgroundThe relationship between sleeping habits and aortic stiffness remains inconclusive and is not fully explored in the European general population.MethodsWe examined cross-sectionally 8659 participants from the Swedish population-based cohort Swedish CArdioPulmonary bioImage Study (SCAPIS), mean age 57.5 years, 52.1% women. A self-administered questionnaire on sleeping habits (duration, qua
Children born to enemy soldiers, so-called “children born of war,” are vulnerable to displacement. The contested repatriations of the children of Scandinavian mothers and foreign fighters from Syria in the wake of the fall of the “Islamic state” in March 2019 are point in case. Norway, Denmark, and Sweden at first delayed and then only hesitantly or selectively supported their return – as Norway a
