Hydration-Induced Structural Changes in the Solid State of Protein : A SAXS/WAXS Study on Lysozyme

The stability of biologically produced pharmaceuticals is the limiting factor to various applications, which can be improved by formulation in solid-state forms, mostly via lyophilization. Knowledge about the protein structure at the molecular level in the solid state and its transition upon rehydration is however scarce, and yet it most likely affects the physical and chemical stability of the bi

New Light on the Mechanism of Phototransduction in Phototropin

Phototropins are photoreceptor proteins that regulate blue light-dependent biological processes for efficient photosynthesis in plants and algae. The proteins consist of a photosensory domain that responds to the ambient light and an output module that triggers cellular responses. The photosensory domain of phototropin from Chlamydomonas reinhardtii contains two conserved LOV (light-oxygen-voltage

Two C-terminal sequence variations determine differential neurotoxicity between human and mouse α-synuclein

Background: α-Synuclein (aSyn) aggregation is thought to play a central role in neurodegenerative disorders termed synucleinopathies, including Parkinson's disease (PD). Mouse aSyn contains a threonine residue at position 53 that mimics the human familial PD substitution A53T, yet in contrast to A53T patients, mice show no evidence of aSyn neuropathology even after aging. Here, we studied the neur

MBBRs as post-treatment to ozonation : Degradation of transformation products and ozone-resistant micropollutants

The degradation potential of micropollutants and transformation products in biological post-treatment after ozonation is partly unknown. A pilot plant with ozonation and subsequent biological treatment in a moving bed biofilm reactor (MBBR) was thus operated over 16 months to investigate the removal of micropollutants and the formation and removal of N-oxide transformation products. Lab-scale kine

Frequency Recognition Algorithm for Multiple Exposures : Snapshot imaging using coded light

The central challenge tackled in this thesis is the development of an optical imaging approach capable of multidimensional image capture of dynamic samples. Many conventional optical imaging approaches, which can obtain dimensional information such as spectral, polarisation, or volumetric, to name a few, about samples either employ sequential image capture or parallelised detector arrangements. Du

Biochemical signatures reveal positive effects of conservation tillage on arbuscular mycorrhizal fungi but not on saprotrophic fungi and bacteria

Since tillage can reduce the amount of organic C stored in soils, the use of conservation tillage practices, which exclude soil inversion, or include it less frequently, is often promoted. Soil microorganisms are closely linked to soil organic C (SOC), and they are assumed to respond quicker to management changes than SOC. Using two Swedish long-term tillage experiments, our aim was to determine w

Photofunctionality of iron(III) N-heterocyclic carbenes and related d5 transition metal complexes

Despite a few reports of photoluminescent and strongly photo-oxidizing transition metal complexes with a d5 electronic configuration, the photophysics and photochemistry of this class of transition metal complexes have largely remained unexplored. Recent investigations of earth-abundant iron(III) N-heterocyclic carbene (NHC) complexes have demonstrated promising photophysical and photochemical pro

Europe in Historical International Relations

Almost any conversation about Historical International Relations (IR) appears to be, at least implicitly, always already about Europe. The geographical and intellectual centrality of Europe shapes the way in which historically oriented work in IR operates. Paradoxically, despite a long and powerful lineage of disciplinary Eurocentrism, Europe has only rarely emerged as a conceptual focal point of

Synchronization in Digital Twins for Industrial Control Systems

Digital twins, which are a new concept in industrial control systems (ICS), play a key role in realizing the vision of a smart factory, and they can have different effective use cases. With digital twins, we have virtual replicas of physical systems so that they precisely mirror the internal behavior of the physical systems. Hence, synchronization is necessary to keep the states of digital twins i

Överlappningen mellan dataskydd och marknadsrätt : Dataskyddsförordningens tillämpning på marknadsföring och marknadsrättens tillämpning på kommersiell personuppgiftsbehandling

Digitaliseringen gör det möjligt för näringsidkare att utveckla nya affärsmodeller, upptäcka nya marknader och att rationalisera sina verksamheter.En viktig aspekt i denna utveckling utgör att samla in, behandla och på olika sätt utnyttja personuppgifter av såväl befintliga som presumtiva kunder. Av den anledningen existerar ett naturligt samband mellan personuppgifter och näringsverksamhet och fr

Ideella organisationers medverkan i tvister på dataskyddsrättens område

EU:s dataskyddsförordning innehåller bestämmelser om vissa ideella organisationers behörighet att uppträda som ombud för registrerade samt om sådan organisationers talerätt. Syftet med denna artikel är att undersöka vilka möjligheter sådana organisationer enligt gällande svensk rätt har att delta i övervakningen av dataskyddsreglernas efterlevnad.

Mass spectrometry-based analysis of formalin-fixed, paraffin-embedded distal cholangiocarcinoma identifies stromal thrombospondin-2 as a potential prognostic marker

Background: Distal cholangiocarcinoma is an aggressive malignancy with a dismal prognosis. Diagnostic and prognostic biomarkers for distal cholangiocarcinoma are lacking. The aim of the present study was to identify differentially expressed proteins between distal cholangiocarcinoma and normal bile duct samples. Methods: A workflow utilizing discovery mass spectrometry and verification by parallel

A sensitive assay for dNTPs based on long synthetic oligonucleotides, EvaGreen dye and inhibitor-resistant high-fidelity DNA polymerase

Deoxyribonucleoside triphosphates (dNTPs) are vital for the biosynthesis and repair of DNA. Their cellular concentration peaks during the S phase of the cell cycle. In non-proliferating cells, dNTP concentrations are low, making their reliable quantification from tissue samples of heterogeneous cellular composition challenging. Partly because of this, the current knowledge related to the regulatio

Trapping and re-use system for radioactive xenon in nuclear medicine

Different methods of trapping radioactive xenon are reviewed. Trapping by adsorption on activated charcoal has the advantage of being simple and cheap and also makes it possible to recycle the xenon. An activated charcoal trapping system is described which can extract 133Xe from 100l of expired air in 10 min from patients undergoing diagnostic pulmonary or circulation studies. Details of the const

The dual photopeak-area method applied to scintillation camera measurements of effective depth and activity of in vivo 123I-distributions

Attenuation curves and photopeak ratios of 159 keV and 28 keV phtons emitted in the decay of 123I have been studied using a scintillation camera equipped with an extra ADC for recording the pulse height distribution of the energy signal. Cavities of various sizes containing 123I-solution were placed at different depths in a water phantom in order to vary the effective depth, i.e., the thickness of
