We report a new design of an acoustophoretic trapping device with significantly increased capacity and throughput, compared to current commercial acoustic trapping systems. Acoustic trapping enables nanoparticle and extracellular vesicle (EV) enrichment without ultracentrifugation. Current commercial acoustic trapping technology uses an acoustic single-node resonance and typically operates at flow
The focus of this thesis is the life and death of adult retinal ganglion cells (RGCs). RGCs are neurons that convey visual information from the retina to higher centers in the brain. If the optic nerve is transected (ONT), adult RGCs die by a form of cell death called apoptosis, and a general hypothesis is that neurotrophic factors can support the survival of injured neurons.With the intention to The focus of this thesis is the life and death of adult retinal ganglion cells (RGCs).

Falsterbo Peninsula on the south coast of Sweden is low-lying and exposed to flooding. In 1872 the extreme storm surge Backafloden caused large devastation on the Swedish, Danish, and German coasts in the South Baltic Sea. For the Falsterbo Peninsula, the peak storm surge level is estimated to have been 240 cm above normal. If a similar event happened today, the consequences would be far worse, as
Microplastics and nanoplastics (MNPs) are ubiquitous environmental pollutants with increasing implications for human health. While their presence in human tissues is established, the molecular mechanisms driving their potential neurotoxicity remain unclear. This study investigates the impact of polystyrene (PS) on amyloid protein misfolding and cellular metabolism using Optical Photothermal Infrar
Heart failure (HF) is a major contributor to global morbidity and mortality. While distinct clinical subtypes, defined by etiology and left ventricular ejection fraction, are well recognized, their genetic determinants remain inadequately understood. In this study, we report a genome-wide association study of HF and its subtypes in a sample of 1.9 million individuals. A total of 153,174 individual
Transplantation of human fetal ventral mesencephalic tissue in individuals with Parkinson's disease has yielded clinical benefits but also side effects, such as graft-induced dyskinesias. The open-label TransEuro trial ( NCT01898390 ) was designed to determine whether this approach could be further developed into a clinically useful treatment. Owing to poor availability of human fetal ventral mese
Climate change is increasingly recognized as a major security concern, with drought–migration–conflict linkages attracting significant attention in both policy and research. While some narratives portray drought as a direct driver of migration and conflict, evidence shows a far more complex relationship: climate stress can lead to more migration in some contexts and less in others, with internal m
Smart microscopy is transforming life sciences by automating experimental imaging workflows and enabling real-time adaptation based on feedback from images and other data streams. This shift increases throughput, improves reproducibility, and expands the functional capabilities of microscopes. However, the current landscape is highly fragmented. Academic researchers often develop custom solutions
Transient activation of fibroblasts into contractile myofibroblasts is essential for extracellular matrix (ECM) production and remodeling during wound healing and tissue regeneration. While ECM-dependent mechanisms mediating transient activation is well studied, how fibroblasts switch from transient to a persistently activated state and drive fibrosis and aberrant tissue repair in diseases such as
Group A Streptococcus (GAS) causes extensive global morbidity and rising rates of invasive disease, for which clinical outcomes remain poor despite antibiotic treatment of susceptible strains. This limitation of current therapy underscores the need for alternative or adjunctive approaches. Antibody-based interventions represent a promising but underexplored strategy. Historically, the streptococca
Introduction: Synovial fibroblasts (S-Fib) are recognized as key drivers of joint inflammation in adult arthritis. Moreover, data are limited on the processes driving monocyte activation in oligoarticular juvenile idiopathic arthritis (oJIA). Therefore, we aimed to explore if S-Fib from patients with oJIA induce monocyte activation. Methods: S-Fib were isolated from the synovial fluid (SF) of n =
Metal oxide nanoparticles are widely used in catalysis, photovoltaics, and gas sensing, where surface structure and oxidation state strongly influence performance. This work investigates how carrier gas composition, combined with in-flight heating, can be used to control the surface properties of metal oxide nanoparticles generated via the gas-phase method, spark ablation. Sn, Zn, and Al nanoparti
This study develops a framework for investigating the spatiotemporal variability of dust storm (DS) susceptibility in a major DS source in the Middle East i.e., Tigris-Euphrates River Basin. Visual interpretation of true color composites of MODIS satellite images was used to identify DS sources during period 2000-2021. In total 1,028 dust storm sources were identified. Incorporating 70% of DS sour
Variation of the blood content of the pulmonary vascular bed during a heartbeat can be quantified by pulmonary blood volume variation (PBVV) using magnetic resonance imaging (MRI). The aim was to evaluate if PBVV differs in patients with heart failure compared to healthy controls and investigate the mechanisms behind the PBVV. Forty-six patients and 10 controls underwent MRI. PBVV was calculated f
Mass spectrometry (MS) and nuclear magnetic resonance (NMR) spectroscopy techniques have been used extensively for metabolite profiling. Although combining these two analytical modalities has the potential of enhancing metabolite coverage, such studies are sparse. In this study we test the hypothesis that combining the metabolic information obtained using liquid chromatography (LC) MS and 1H NMR s
