Studies on growth of the small intestine have mostly concentrated on crypt hyperplasia rather than crypt fission (CF). The process of crypt bifurcation has been identified in rodents and humans but not in swine. The main aims of this study were: 1) to investigate quantitatively crypt fission in the small intestine mucosa of pigs of different age-groups and 2) to assess the effect of colostrum and

Research on media and democracy mobilizes a range of conceptual versions of the subject. This is often done implicitly, or out of habit, with a specific model becoming established in any given research tradition. This presentation argues that different theories of the subject can have different implications for our understanding of citizenship and democracy. The text surveys a number of versions,

Prolonged periods of allopatry might result in loss of the ability to discriminate against other formerly sympatric species, and can lead to heterospecific matings and hybridization upon secondary contact. Loss of premating isolation during prolonged allopatry can operate in the opposite direction of reinforcement, but has until now been little explored. We investigated how premating isolation bet

Characteristics of nanoscale materials are often different from the corresponding bulk properties providing new, sometimes unexpected, opportunities for applications. Here we investigate the properties of 8 nm colloidal nanoparticles of MAPbBr3 perovskites and contrast them to the ones of large microcrystallites representing a bulk. X-ray spectroscopies provide an exciton binding energy of 0.32 ±

Prominent in the sky, but not visible to humans, is a pattern of polarized skylight formed around both the Sun and the Moon. Dung beetles are, at present, the only animal group known to use the much dimmer polarization pattern formed around the Moon as a compass cue for maintaining travel direction. However, the Moon is not visible every night and the intensity of the celestial polarization patter

Here, we report and investigate the genomic alterations of two novel cases of Non-Hodgkin Lymphoma (NHL) in children with Williams-Beuren syndrome (WBS), a multisystem disorder caused by 7q11.23 hemizygous deletion. Additionally, we report the case of a child with NHL and a somatic 7q11.23 deletion. Although the WBS critical region has not yet been identified as a susceptibility locus in NHL, it h

The development of mesencephalic dopamine neurons and their survival later in life requires the continuous presence of the transcription factor Nurr1 (NR4A2). Nurr1 belongs to the nuclear receptors superfamily. However, it is an orphan member that does not require a ligand to regulate the transcription of its target genes. Therefore, controlling the expression of Nurr1 is an important manner to co

We are an international collective of Early Career Academics (ECAs) who met throughout 2020 to explore the implications of COVID-19 on precarious academics. With this intervention, our aims are to voice commonly shared experiences and concerns and to reflect on the extent to which the pandemic offers opportunities to redefine Higher Education and research institutions, in a context of ongoing prec

Fibrillar protein aggregates are a hallmark of a range of human disorders, from prion diseases to dementias, but are also encountered in several functional contexts. Yet, the fundamental links between protein assembly mechanisms and their functional or pathological roles have remained elusive. Here, we analyze the aggregation kinetics of a large set of proteins that self-assemble by a nucleated-gr

The refusal to shake hands with a female reporter by a Muslim politician from the Miljöpartiet resulted in a controversy in Sweden. Together with a number of court cases, it revealed a disparity between the established judicial line and the views of the general public. The Swedish controversy received a response from Denmark, where the ruling coalition introduced new citizenship legislation with a

Infusion of large amounts of intravenous immunoglobulin (IVIG) or anti-D can reverse the low platelet count in patients with ITP within hours of the initiation of treatment. In some cases, the effects of IVIG appear to far outlast several half-lives of the product. Several mechanisms have been proposed to explain these rapid and long term effects and these will be discussed in this review.

Autoimmune thrombocytopenic purpura (AITP) is a bleeding disease in which autoantibodies are directed against the individual's own platelets, resulting in enhanced Fc-mediated platelet destruction by macrophages in the reticuloendothelial system. Most research in AITP has focused on characterization of the autoantibodies, while little has been devoted to the cellular immune mechanisms leading to a

This study explores the effectiveness of combining Electrical Resistivity Tomography (ERT) and Induced Polarization (IP) for identifying internal erosion processes in embankment dams. A small-scale test dam was built in Älvkarleby, Sweden, with deliberately embedded but undisclosed defects to test monitoring capabilities. Daily ERT and IP measurements were collected during 4.5-year years, and anal

This thesis consists of four self-contained papers in the economics of education and labor economics.In the first chapter, we study whether differences in teacher quality across countries are a contributor of international learning gaps. In particular, we study the effects of two dimensions of teacher quality, subject knowledge and didactic skills, on student learning in francophone Sub-Saharan Af

Gambling has become a prominent feature of Central Asia's shifting economies, reshaping social life and governance across the region. While some states maintain prohibitions, others, including Kazakhstan, have legalized gambling as a tool for revenue generation and tourism development. This expansion, however, has produced significant social costs, including family disruption, rising indebtedness

This article examines the ways in which parenting practices of refugee parents are the object of concern for the Danish welfare state. Emphasis is placed on how interventions of daycare institutions and other welfare professionals have been experienced by refugee families who live in a context of radical uncertainty since they hold temporary residence permits in Denmark. Based on ethnographic fiel

The 2011 UN Guiding Principles on Business and Human Rights (UNGPs) introduced human rights due diligence (HRDD) as a societal expectation to businesses to implement a new kind of due diligence risk management process to ‘know and show’ they respect human rights. Ten years later, mandatory human rights due diligence (mHRDD) legislation imposing a legal duty to carry out HRDD has become mainstream

Transposable elements (TE) are parasitic genetic entities that have the ability to alter their position within a genome and have the potential to influence its functionality. Although TEs play beneficial roles in the evolution of their host, they are active in various human disorders including neurological diseases, where may contribute to the progress of the disease. Long Interspersed Nuclear Ele
