The stability of proteins is an essential property that has several biological implications. Knowledge about protein stability is important in many ways, ranging from protein purification and structure determination to stability in cells and biotechnological applications. Experimental determination of thermal stabilities has been tedious and available data have been limited. The introduction of li
From liquefied human seminal plasma, we purified the predominant basic protein which appears following liquefaction of coagulated semen. The protein was purified in the presence of di-isopropylfluorophosphate to retard its degradation. Heparin-Sepharose® chromatography was followed by gel filtration (Biogel® P 60) and by fast performance liquid chromatography on a reversed phase column (C8). The b
The PNPLA3 I148M variant is the major genetic risk factor for all stages of fatty liver disease, but the underlying pathophysiology remains unclear. We studied the effect of this variant on hepatic metabolism in homozygous carriers and non-carriers under multiple physiological conditions with state-of-the-art stable isotope techniques. After an overnight fast, carriers had higher plasma β-hydroxyb
Stød is a syllable rhyme prosody that is realized as creaky voice, and its distributionis partly predictable. To examine listeners’ implicit knowledge of the complicatednature of stød distribution, we conducted a lexical decision task, investigating anirregularly behaving group of nouns in which stød distribution is unpredictable.We hypothesized that listeners would be the most surprised by deviat
This paper presents new estimates of the material livings standards among the rural population in southern Sweden from the 1680’s up to 1865. Utilizing a newly constructed database of circa 1800 probate inventories from the benchmark periods 1680-1720, 1780-85, and 1860-65, we analyse the development of consumption patterns for rural households. Wefind that that all rural households, no matter the
Due to the honey bee's importance as a simple neural model, there is a great need for new functional imaging modalities. Herein we report on the development and new finding of a combined two-photon microscope with a synchronized odor stimulus platform for in-vivo functional and morphological imaging of the honey bee's olfactory system focusing on its primary centers, the antennal lobes (ALs). Our
Haemophilia B (HB) is a rare inherited bleeding disorder caused by the deficiency of coagulation factor IX (FIX). The major clinical issues are bleedings, often targeting the joints, and the development of neutralising antibodies, i.e. inhibitors, to the FIX replacement therapy. Historically HB has been seen as identical to the more common haemophilia A (HA), i.e. deficiency of coagulation factor
Background: The combination of infliximab and immunosuppressant therapy is a standard management strategy for patients with Crohn's disease. Concerns regarding the implications of long-term combination therapy provided the rationale for a formal clinical trial of treatment de-escalation. Our aim was to compare the relapse rate and the time spent in remission over 2 years between patients continuin
To increase engagement with science and technology, young people around the world are encouraged to attend activities at science centers. But how effective are these activities? Since women have weaker ability beliefs and interest in technology than men, it is especially important to learn how science center visits affect them. In this study, we tested if programming exercises offered to middle sc
A modern diesel engine is a reliable and efficient mean of producing power. A way to reduce harmful exhaust and greenhouse gas (GHG) emissions and secure the sources of energy is to develop technology for an efficient diesel engine operation independent of fossil fuels. Renewable diesel fuels are compatible with diesel engines without any major modifications. Rapeseed oil methyl esters (RME) and o
BACKGROUND: The risks of developmental language disorder (DLD) for both educational progress and socio-emotional development are well documented, but little is known about how children and young people with DLD experience and describe their language and communication. The need to complement experimental and quantitative studies with qualitative perspectives of the lived experience of individuals w
Dissolved Organic Carbon (DOC) in inland waters plays an essential role in the global carbon cycle and has significant public health effects. Machine learning (ML) together with remote sensing has emerged as a powerful and promising combination to quantify water quality parameters from space. However, inland water sample data for DOC is limited. Hence, little is known about the potential to quanti
Background: Criteria for electrocardiographic detection of acute myocardial ischemia recommended by the Consensus Document of ESC/ACCF/AHA/WHF consist of two parts: The ST elevation myocardial infarction (STEMI) criteria based on ST elevation (ST↑) in 10 pairs of contiguous leads and the other on ST depression (ST↓) in the same 10 contiguous pairs. Our aim was to assess sensitivity (SE) and specif
BACKGROUND: Berry pomace is a valuable but little used by-product of juice manufacturing. When processed to a stable fruit powder, the composition differs from that of the whole fruit. To facilitate application in foods, a detailed knowledge of its composition and physicochemical properties is essential. RESULTS: Blackcurrant, redcurrant, chokeberry, rowanberry and gooseberry were selected for ana
Here, we report on the growth, electronic, and surface properties of the electron-doped half-Heusler series Co1-xNixTiSb (001) grown by molecular beam epitaxy. High-quality epitaxial growth of thin films is achieved on InP (001) substrates using an InAlAs buffer layer for all nickel concentrations. The semiconductor to metal transition as a function of substitutional alloying was examined using el
The precisionFDA Truth Challenge V2 aimed to assess the state-of-the-art of variant calling in difficult-to-map regions and the Major Histocompatibility Complex (MHC). Starting with FASTQ files, 20 challenge participants applied their variant calling pipelines and submitted 64 variant callsets for one or more sequencing technologies (~35X Illumina, ~35X PacBio HiFi, and ~50X Oxford Nanopore Techno
The development of innovative and competitive products and mastery of IT&T technologies are crucial for a company's long-term success in the global market. The main flag bearers for development are product developers, but it is questionable whether the existing systems are appropriate for the education of such professionals. For example, one study found large deficiencies concerning their skil
It is unknown whether patients as a consequence of prosthetic joint replacement are at a higher risk of developing cancer. We therefore analyzed cancer incidence following prosthetic knee replacement (TKR). The observed cancer incidence in 14,551 patients from the population-based Swedish Knee Arthroplasty Register who have undergone TKR because of osteoarthrosis (OA, n = 10,120) or rheumatoid art
The regulations on the emissions from combustion devices are getting more and more strict for environmental and human health reasons. Modern combustion research faces two major challenges; reduction of the pollutants, such as CO, NOx and unburnt hydro- carbons and increase of the combustion efficiency. Current trend for stationary power generation is to use lean premixed and/or pre-vaporized combu
Hippocampal extracellular levels of noradrenaline (NA), 5-hydroxytryptamine (5-HT), and 5-hydroxyindoleacetic acid (5-HIAA) were monitored with the microdialysis technique in freely moving rats. In one experiment 30 min samples were collected during 24 h of continuous perfusion, and the monoamine output was compared to the behavioural activity state, as arbitrarily classified in three categories:
