Population dynamics of the butterfly Pyrgus armoricanus after translocation beyond its northern range margin

Translocation experiments can be used to study the factors limiting species' distributions and to infer potential drivers of successful colonisation during range shifts. To study the expansion dynamics of the butterfly Pyrgus armoricanus in southern Sweden and to find out whether its distribution was limited by climate, translocation experiments were carried out within and 50–60 km beyond its natu

Methylation patterns and chromatin accessibility in neuroendocrine lung cancer

Lung cancer is the worldwide leading cause of death from cancer. Epigenetic modifications such as methylation and changes in chromatin accessibility are major gene regulatory mechanisms involved in tumorigenesis and cellular lineage commitment. We aimed to characterize these processes in the context of neuroendocrine (NE) lung cancer. Illumina 450K DNA methylation data were collected for 1407 lung

The Historical Origins of the Mortality Gradient : Socioeconomic Inequalities in Adult Mortality over Two Centuries in Sweden

Mortality differentials by socioeconomic status (SES) are among the most pervasive facts of contemporary demography. However, while the mortality gradient by income, class and education is well-established for the period after 1970, evidence regarding the origins of the gradient is still scarce. The aim of this thesis is to explore the development of SES differences in all-cause and cause-specific

CD163+ macrophages are associated with a vulnerable plaque phenotype in human carotid plaques

Macrophages are a functionally heterogeneous group of immune cells abundant in atherosclerotic plaques. Macrophages expressing CD163 are associated with intraplaque hemorrhage and have previously been considered atheroprotective. However, in a recent study CD163-deficient atherosclerotic ApoE−/− mice exhibited smaller and less complex plaques, suggesting a proatherogenic role of CD163. Previous sm

Prognosis of Syncope With Head Injury : a Tertiary Center Perspective

Aim: Head injury is the most common trauma occurring in syncope. We aimed to assess whether syncope as cause of head-trauma affects short-and long-term prognosis. Methods: From a database retrospective analysis of 97,014 individuals attending Emergency Department (ED), we selected data of patients with traumatic head injury including age, gender, injury mechanism, brain imaging, multiple traumas,

Computational Atomic Structure: Applications to Astrophysics and Nuclear Structure

This thesis deals with the modelling of atoms and ions. In heavy systems, where the effect of the nuclear size must be considered, a fully relativistic treatment based on the Dirac-Coulomb Hamiltonian is needed. Chapter two of the thesis provides an introduction to the basic principles of the fully relativistic multiconfiguration Dirac-Hartree-Fock (MCDHF) method, which is a variational approach f

Do Preparatory Programming Lab Sessions Contribute to Even Work Distribution in Student Teams?

Unfair work distribution is common in project-based learning with teams of students. One contributing factor is that students are differently skilled developers. To mitigate the differences in a course with group work, we introduced mandatory programming lab sessions. The intervention did not affect the work distribution, showing that more is needed to balance the workload. Contrary to our goal, t

Where does the elephant come from? The evolution of causal cognition is the key

Osiurak and Reynaud do not explain the evolutionary emergence and development of the elephant in the room, that is, technical cognition. We first argue that there is a tight correlation between the evolution of cumulative technological culture (CTC) and the evolution of reasoning about abstract forces. Second, intentional teaching plays a greater role in CTC evolution than acknowledged in the targ

Dementia

Dementia is a decline in cognitive function that impairs a person's previous level of social and occupational function. Dementia is a very common medical condition that can result from diverse causes. Dementias are classified based on common clinical, genetic, and neuropathological features. The most common cause of dementia is Alzheimer's disease. Other major classes of disorders that cause demen

Generation and regulation of β-amyloid peptide variants by neurons

Studies of processing of the Alzheimer β-amyloid precursor protein (βAPP) have been performed to date mostly in continuous cell lines and indicate the existence of two principal metabolic pathways: the 'β- secretase' pathway, which generates β-amyloid (Aβ(1-40/42); ~4 kDa), and the 'α-secretase' pathway, which generates a smaller fragment, the 'p3' peptide (Aβ(17-40/42); ~3 kDa). To determine whet
