Single-cell genomics of a bloom-forming phytoplankton species reveals population genetic structure across continents

The study of microbial diversity over time and space is fundamental to the understanding of their ecology and evolution. The underlying processes driving these patterns are not fully resolved but can be studied using population genetic approaches. Here we investigated the population genetic structure of Gonyostomum semen, a bloom-forming phytoplankton species, across two continents. The species ap

Gene fusions and microRNAs in cancer

The genome of cancer cells is unstable. Flaws in the DNA repair mechanisms of these cells can lead to the creation of gene fusions, where parts of two different genes are erroneously combined. Additionally, the expression of microRNAs (miRNAs), small regulatory molecules that control gene activity, is often dysregulated in cancer. In this thesis, we investigate miRNAs, gene fusions, and the interp

Swedish crisis preparedness planners' understanding and sense-making of preparedness work in a public organisation : Implications for future development

The sometimes rapid development of (new) threats and extraordinary events calls for a robust, flexible, and well-equipped civil crisis preparedness system to respond and limit the damage of crisis events. To achieve this, Swedish municipalities and regions are required by law to regularly perform and report risk and vulnerability analysis ‘bottom up’ to governmental agencies. When performed in lar

Noninvasive Pressure-Volume Loops Predict Major Adverse Cardiac Events in Heart Failure With Reduced Ejection Fraction

Background: Heart failure with reduced ejection fraction (HFrEF) is characterized by ventricular remodeling and impaired myocardial energetics. Left ventricular pressure-volume (PV) loop analysis can be performed noninvasively using cardiovascular magnetic resonance (CMR) imaging to assess cardiac thermodynamic efficiency. Objectives: The aim of the study was to investigate whether noninvasive PV

L-type Amino Acid Transporter 1 as a Therapeutic Target in Pancreatic Cancer

Metabolic rewiring is a key feature of cancer cells to support the demands of growth and proliferation. The metabolism of amino acids is altered in many cancers, including pancreatic cancer. The cellular uptake of amino acids is regulated by amino acid transporters, such as L-type amino acid transporter 1 (LAT1). Accumulating evidence suggests that LAT1 is overexpressed in pancreatic cancer and co

Coherent phonon spectroscopy of solid/liquid interfaces

Solid-liquid interfaces are at the heart of a wide variety of phenomena. Their investigation requires experimental techniques with surface sensitivity such scanning probe microscopy and nonlinear optical techniques. In recent years, solid-liquid interfaces have been investigated with a novel approach based on the generation of high frequency acoustic and optical phonons. Due to the sensitivity of

Combining Scattering Experiments and Colloid Theory to Characterize Charge Effects in Concentrated Antibody Solutions

Charges and their contribution to protein-protein interactions are essential for the key structural and dynamic properties of monoclonal antibody (mAb) solutions. In fact, they influence the apparent molecular weight, the static structure factor, the collective diffusion coefficient, or the relative viscosity, and their concentration dependence. Further, charges play an important role in the collo

Thyroid disease in ANCA-associated vasculitis : a clinical and epidemiological study

Objectives To describe clinical and laboratory characteristics and outcomes in patients with antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) and thyroid disease (TD). We also aimed to calculate incidence and identify predictors of TD in two large cohorts of patients with AAV. Methods The study comprised 644 patients with AAV in a population-based cohort from southern Sweden

Infective native aneurysms of the infrapopliteal arteries – A systematic literature review and report of two cases

Infective native aneurysms (INA) of the infrapopliteal arteries are rare and have previously been poorly described. This systematic review aims to provide an overview of the literature of this entity. Furthermore, two case reports of our own clinical experience are presented. PubMed, ScienceDirect, Cochrane, Ovid Embase, Ovid MEDLINE, and Web of Science were searched for articles on INAs of the in

Characterization of Trapping Effects Related to Carbon Doping Level in AlGaN Back-Barriers for AlGaN/GaN HEMTs

The impact of different carbon concentrations in the Al 0.06 Ga 0.94 N graded back-barrier and GaN buffer of high electron mobility transistors (HEMTs) is investigated. Four epi-wafers with different carbon concentrations, ranging from 1 × 10 17 to 5 × 10 17 cm −3 , were grown by metal organic chemical vapor deposition (MOCVD). HEMTs with 100 and 200 nm gate lengths were fabricated and characteriz

Rational molecular design of partly fluorinated fuel cell membranes with high proton conductivity under low-humidity conditions

Research on proton exchange membranes (PEMs) is closely tied to the development of PEM fuel cells, and the need to overcome the shortcomings of perfluorosulfonic acid PEMs. One of the key challenges is to devise efficient molecular designs towards PEMs with sufficient durability and proton conductivity under reduced humidity. Here, we report on a series of partly fluorinated PEMs based on high-mol

Examining labelling guidelines for AI-based software as a medical device : A review and analysis of dermatology mobile applications in Australia

In recent years, there has been a surge in the development of AI-based Software as a Medical Device (SaMD), particularly in visual specialties such as dermatology. In Australia, the Therapeutic Goods Administration (TGA) regulates AI-based SaMD to ensure its safe use. Proper labelling of these devices is crucial to ensure that healthcare professionals and the general public understand how to use t

Weyl spin-momentum locking in a chiral topological semimetal

Spin-orbit coupling in noncentrosymmetric crystals leads to spin-momentum locking – a directional relationship between an electron’s spin angular momentum and its linear momentum. Isotropic orthogonal Rashba spin-momentum locking has been studied for decades, while its counterpart, isotropic parallel Weyl spin-momentum locking has remained elusive in experiments. Theory predicts that Weyl spin-mom
