Superparamagnetic iron oxide nanoparticles (SPIONs) as a multimodality imaging probe for sentinel nodes : Design and Preclinical Evaluation

Bröst- och hudcancerceller sprider sig via lymfatiska systemet och fastnar i en eller två regionala sentinel lymfnoder (SLN) där de med stor sannolikhet växer till metastaser. Därför är SLN-biopsier och relaterade histopatologiska undersökningar viktiga vid cancerdiagnostiken för att bestämma sjukdomsstatus och att från denna kunna bestämma rätt behandling. Patienter vars lymfnoder innehåller spri

Desaturation effects of pyrite–sand mixtures on induced polarization signals

Induced polarization (IP) is an acknowledged method in ore exploration and can be applied to evaluate the metal content in dumps containing the residues of ore processing facilities. Existing models explain the relationships between ore content and grain size of the ore particles with IP parameters. However, the models assume full water saturation of the ore containing samples, which is often not

De novo DHDDS variants cause a neurodevelopmental and neurodegenerative disorder with myoclonus

Subcellular membrane systems are highly enriched in dolichol, whose role in organelle homeostasis and endosomal-lysosomal pathway remains largely unclear besides being involved in protein glycosylation. DHDDS encodes for the catalytic subunit (DHDDS) of the enzyme cis-prenyltransferase (cis-PTase), involved in dolichol biosynthesis and dolichol-dependent protein glycosylation in the endoplasmic re

Poorly Expressed Alleles of Several Human Immunoglobulin Heavy Chain Variable Genes are Common in the Human Population

Extensive diversity has been identified in the human heavy chain immunoglobulin locus, including allelic variation, gene duplication, and insertion/deletion events. Several genes have been suggested to be deleted in many haplotypes. Such findings have commonly been based on inference of the germline repertoire from data sets covering antibody heavy chain encoding transcripts. The inference process

Critical biomass harvesting – Applying a new concept for Swedish forest soils

The contribution of forest harvesting to base cation losses and soil acidification has increased in recent years in Sweden, as the demand for bioenergy has increased and the sulphur deposition has decreased. Thus, new policy tools are required to evaluate the progress of the recovery from acidification, and as a basis for forest management recommendations. In this study we introduce and test a con

Investigating Partially Discordant Results in Phase 3 Studies of Aducanumab

Objectives: Efficacy and safety results from the EMERGE (NCT02484547) and ENGAGE (NCT02477800) phase 3 studies of aducanumab in early Alzheimer’s disease (AD) have been published. In EMERGE, but not in ENGAGE, high-dose aducanumab demonstrated significant treatment effects across primary and secondary endpoints. Low-dose aducanumab results were consistent across studies with non-significant differ

Combining dense and sparse labeling in optical DNA mapping

Optical DNA mapping (ODM) is based on fluorescent labeling, stretching and imaging of single DNA molecules to obtain sequence-specific fluorescence profiles, DNA barcodes. These barcodes can be mapped to theoretical counterparts obtained from DNA reference sequences, which in turn allow for DNA identification in complex samples and for detecting structural changes in individual DNA molecules. Ther

Plateaus and jumps in the atmospheric radiocarbon record - Potential origin and value as global age markers for glacial-to-deglacial paleoceanography, a synthesis

Changes in the geometry of ocean meridional overturning circulation (MOC) are crucial in controlling past changes of climate and the carbon inventory of the atmosphere. However, the accurate timing and global correlation of short-term glacial-to-deglacial changes of MOC in different ocean basins still present a major challenge. The fine structure of jumps and plateaus in atmospheric and planktic r

Late Holocene peat paleodust deposition in south-western Sweden - exploring geochemical properties, local mineral sources and regional aeolian activity

Atmospheric mineral dust not only interacts with the climate system by scattering incoming solar radiation and affecting atmospheric photochemistry, but also contributes critical nutrients to marine and terrestrial ecosystems. In a high-resolution analysis of paleodust deposition, peat development and soil dust sources, we assess the interplay between dust deposition and bog development of the Dav

Effects of common European tree species on soil microbial resource limitation, microbial communities and soil carbon

Studies of tree species effects on soils have revealed a significant impact on soil organic carbon (SOC) stocks and the carbon (C) distribution between forest floor and mineral soil, but the underlying mechanisms including the roles of litter traits, soil properties, and microbiome remain unclear. To address this challenge, we tested the effect of six common European tree species on the quality an

On the Utility of Representation Learning Algorithms for Myoelectric Interfacing

När vi människor försöker röra på oss skickas elektriska impulser genom nervsystemet från hjärnan ner till de muskler som är inblandade i den tilltänkta rörelsen. Att kunna mäta sådana nervimpulser hade varit av värde för en rad tillämpningar—information hade då kunnat överföras direkt från nervsystemet utan att gå via långsamma, mekaniska gränssnitt så som tangentbord och pekskärmar. OlyckligtvisElectrical activity produced by muscles during voluntary movement is a reflection of the firing patterns of relevant motor neurons and, by extension, the latent motor intent driving the movement. Once transduced via electromyography (EMG) and converted into digital form, this activity can be processed to provide an estimate of the original motor intent and is as such a feasible basis for non-invas

Structure and dynamics of hydrogen sorption in mesoporous MCM-41

Adsorption isotherms taken at temperatures ranging from 20 to 77 K show a large pore volume and surface area of 980 m2 g-1 for the physical adsorption of molecular hydrogen on MCM-41. The adsorbed hydrogen behaves more like a solid than a liquid and isosteric heats of adsorption reveal a heterogenous surface. The evaporation behaviour of the adsorbed hydrogen indicates that the hexagonally packed

HÉR! An Exploration of Artistic Agency

This doctoral thesis is concerned with agency in the work of a performer, curator, and composer, and how these agencies are socio-culturally constructed. Grounded in creative practice as primary research methodology, the project builds on feedback loops between creation, analysis, and interpretation. The aim is to better understand the conventional norms that define the roles of composer and perfo

Packaging innovation scorecard

Innovation literature shows that the characteristics of a company's innovation processes determine their performance in different areas. In this study, we adopt a general conceptual model from innovation theory and apply it to packaging innovation. This helps identify and describe subprocesses in packaging innovation and how to measure their performance. It also links the packaging innovation proc

Markers of Atrial Myopathy in the General Population : Prevalence, Predictors, and Inter-Relations

BACKGROUND: Atrial myopathy refers to structural and functional cardiac abnormalities associated with atrial fibrillation and stroke, but appropriate diagnostic criteria are lacking.OBJECTIVES: This study aimed to assess prevalence, clinical correlates, and overlap between potential atrial myopathy markers.METHODS: The population-based SCAPIS (Swedish CArdioPulmonary bioImage Study) prospectively

Signaling to the immature brain - Choroid plexus, insulin-like growth factor 1 and extracellular vesicles

I Sverige överlever idag uppemot 80% av de barnen som är födda extremt för tidigt (födda innan graviditetsvecka 28). Dock medföljer en hög sjuklighet, där uppemot 20% av barnen utvecklar olika sjukdomstillstånd såsom blödning i hjärnas hålrum, även kallat intra-ventrikulär hjärnblödning (IVH). Dessutom löper de extremt för tidigt födda barnen en ökad risk att utveckla en intellektuell och neurologExtremely preterm infants (i.e., born below 28 gestational weeks), are at high risk of developing brain morbidities including intraventricular hemorrhage (IVH) and neurodevelopmental impairment. Despite over 50 years of research, there is currently no effective therapy available for preventing IVH. Insulin-like growth factor 1 (IGF-1) plays a pivotal role in perinatal development. Extremely preter

Denna uppsats undersöker NJA 2023 s. 393 (”Vapenattrappen”), och dess konsekvenser för såväl gällande rätt som domstolarnas rättstillämpning. Domen kom under våren 2023 att kritiseras hårt. I målet stod två män åtalade för försök till vapenbrott, eftersom de påstods ha försökt inneha vapen. Vapnen byttes emellertid ut mot en ofarlig attrapp av polis ca. fyra månader innan de tilltalade dök upp, vaThis paper examines NJA 2023 s. 393 ("The Dummy Weapon"), and its consequences for both current law and practical legal application. The verdict would come to be heavily criticized during the spring of 2023. Two men were prosecuted in the case. They were charged with attempted exceptionally aggravated weapons offence, since they had allegedly tried to possess firearms. The firearms had,

Vegetation phenology derived using the plant phenology index and the normalized difference vegetation index for the Balkan peninsula, south-eastern Europe

This study analyses the performance of the satellite derived Plant Phenology Index (PPI) against the Normalized Difference Vegetation Index (NDVI) for estimating start of season (SOS) and end of season (EOS) of vegetation growth in part of the Balkan Peninsula, Southeastern Europe (2000 – 2016). Results revealed that PPI and NDVI differ considerably; SOS and EOS may diverge by more than one month
