Methylglyoxal (MGO) is an endogenous toxin, mainly produced as a by-product of glycolysis that has been associated to aging, Alzheimer's disease, and inflammation. Cell culture studies reported that MGO could impair the glyoxalase, thioredoxin, and glutathione systems. Thus, we investigated the effect of in vivo MGO administration on these systems, but no major changes were observed in the glyoxal
In a wireless communication system, the radio propagation channel is a complicated component to characterise. Channel sounding equipment thus has to meet specific criteria to extract the desired channel parameters. In this study, the authors outline the development and validation of a vector network analyser (VNA) based channel sounder for the frequency range from 1 to 50 GHz using radio-over-fibr
We revisit a Swedish comprehensive school reform first evaluated by Meghir and Palme (2005). This reform increased years of schooling and abolished tracking. We extend the original analysis to the full population and introduce an improved education measure. Our results confirm the original overall finding of small average earnings effects. However, we find considerably larger increases in educatio
Wear mechanisms and failure modes were investigated for autoclave-cured, woven carbon fiber-reinforced polymer (CFRP) composite gears in a mesh with a surface-hardened, 42CrMo4 steel pinion. The reference gears (m = 1 mm, b = 2 mm, z = 20) were tested at torque levels ranging from 0.4 Nm to 0.8 Nm. The temperature was monitored with a thermographic camera, while the gear damage and wear volume wer
In September 2019, the third Global Climate Strike organized by the Fridays For Future (FFF) protest campaign mobilized 6000 protest events in 185 countries and brought 7.6 million participants out onto the streets. This report analyses survey data about participants from 19 cities around the world and compares it to data from an international survey conducted in 13 European cities in March 2019.
Inborn errors of metabolism (IEMs) are characterized by deficits in metabolic enzymes as a result of an inherited disease, leading to the accumulation or decreased excretion of proteins, carbohydrates and lipids. Although IEMs are often diagnosed during childhood, adolescent and adult onset variants may be accompanied by less somatic and more psychiatric manifestations, which often hampers recogni
Patients with immune-mediated kidney diseases are at increased risk of severe coronavirus disease 2019 (COVID-19). The international rollout of COVID-19 vaccines has provided varying degrees of protection and enabled the understanding of vaccine efficacy and safety. The immune response to COVID-19 vaccines is lower in most patients with immune-mediated kidney diseases; either related to immunosupp
In this intervention, we call for extending the critical lens of intersectionality to the field of climate justice. We do so by identifying the theoretical and methodological links through which intersectionality can benefit climate change studies. These include common roots in radical theory, a focus on marginalized populations, challenging dominant epistemologies and ontologies, similar strategi
Välkommen till framtiden! Men vilken framtid? Framtiden som begrepp är både mångtydigt och politiskt laddat. Å ena sidan framställs den som en naturlig förlängning av det förflutna och som något som kan planeras, styras och förutses. Å andra sidan öppnar begreppet framtider i plural för en kamp mellan olika visioner och en omförhandling av de historieskrivningar som legitimerar vissa framtider fra
It has been a mystery that the detected fluorescence intensity of single MEH-PPV molecules is much lower than expected based on their chain length. In this review, after re-evaluating of the literature data in the light of new specially designed experiments, we present a comprehensive explanation of this issue: The actual size of MEH-PPV molecules at single molecule level is much smaller than expe
This article explores the relationship between statelessness and refugeeness over time and space. It does so by drawing on how Palestinian refugees from Syria in Sweden navigate the various stateless and refugee labels imposed upon them before, during and after their flight from Syria to Sweden. Standpoint theory was deployed as the basis for understanding how this group of stateless refugees rela
Svensk Kolinlagring och Lunds universitet (LUCSUS) samlade 19 personer för en workshop på Torsåker gård i syfte att diskutera styrmedel och strategier för att öka kolinlagringen i jordbruksmark, och hur dessa verktyg skulle kunna utformas för att stödja en omställning till ett socialt och ekologiskt hållbart matsystem. Deltagarna representerade olika delar och nivåer av matsystemet och bidrog med
Hydrogels for biomedical applications have been widely studied once they are able to enhance the wound-healing process, as well as facilitate the controlled release and loading of drugs. In this context, Pluronic F127 (PF127) has a major role as it was shown to have exceptional versatility, once it holds unique gelation properties, as it is thermoreversible and is liquid in lower temperatures, and
We propose and analyze a novel scheme based on LDPC codes for quantitative group testing. The key underlying idea is to augment the bipartite graph by introducing hidden non-binary variables to strengthen the message-passing decoder. This is achieved by grouping items into bundles of size q within the test matrix, while keeping the testing procedure unaffected. The decoder, inspired by some works
Construction of the MAX IV facility started early this year. The facility will include two storage rings for the production of synchrotron radiation. The 3 GeV ring will house insertion devices for the production of x-rays while the 1.5 GeV ring will serve UV and IR users. Recently, the lattices for the storage rings in the MAX IV facility were updated. In the 3 GeV storage ring the vertical beam
