BackgroundConcerns around staffs’ and students’ interactions with commercial entities, for example drug companies, have led several North American medical schools to implement conflict of interest (COI) policies. However, little is known about COI policies at European medical schools. We analysed the content and strength of COI policies at Scandinavian medical schools.MethodsWe searched the websit
Background: In the validation of new imaging technology for children with Hirschsprung’s disease (HSCR), basic anatomical parameters of the bowel wall must be established specifically for this patient group. Aim: To explore differences in histoanatomical layers of bowel wall, comparing ganglionic and aganglionic bowel walls, and to examine if the bowel wall thickness is linked to patient weight. M
Objectives: : Knowledge of the correspondence between clinical ICD diagnoses and classification criteria fulfilment is crucial to interpret studies identifying cases via ICD codes. We assessed the degree to which patients registered with ICD-10 diagnoses of psoriatic arthritis (PsA) in the Swedish National Patient Register (NPR) fulfil established PsA classification criteria. Method: Four hundred
Hydroxyapatite (HA) has been widely used as a bone substitute and more recently as a carrier for local delivery of bone targeted drugs. Majority of the approved HA based biomaterials and drug carriers comprise of micrometer sized particulate HA (mHA) or granules and can therefore only be used for extracellular drug release. This shortcoming could be overcome with the use of cell penetrating HA nan
The MAM blood group system (International Society of Blood Transfusion [ISBT] 041) consists of one high-prevalence antigen to date, first detected in a 31-year-old woman during her third pregnancy. Epithelial membrane protein 3 (EMP3) was recently identified as the gene coding the MAM antigen. Six unique genetic variants have been described in EMP3 in 11 MAM- individuals. EMP3 is an 18-kDa glycopr
In the pulp and paper industry, about 5 Mt/y chemithermomechanical pulp (CTMP) are produced globally from softwood chips for production of carton board grades. For tailor making CTMP for this purpose, wood chips are impregnated with aqueous sodium sulphite for sulphonation of the wood lignin. When lignin is sulphonated, the defibration of wood into pulp becomes more selective, resulting in enhance
In situ stability studies of an IrO2(110)-TiO2(110) model electrode are carried out under acidic water electrolysis conditions, employing synchrotron-based techniques including surface X-ray diffraction (SXRD) and X-ray reflectometry (XRR) with a photon energy of 21.5 keV. These experiments are complemented by ex situ scanning electron microscopy (SEM), scanning tunneling microscopy (STM), and X-r
Pro-inflammatory and amyloidogenic S100A9 protein is central to the amyloid-neuroinflammatory cascade in neurodegenerative diseases. Polyoxometalates (POMs) constitute a diverse group of nanomaterials, which showed potency in amyloid inhibition. Here, we have demonstrated that two selected nanosized niobium POMs, Nb10 and TiNb9, can act as potent inhibitors of S100A9 amyloid assembly. Kinetics ana
Co-design processes are of key importance in planning and implementing Nature-based Solutions (NBS), but require boundary management between diverse holders of local, practical and scientific knowledge. Participatory and mapbased planning tools, such as Geodesign workshops, can facilitate such boundary management through mobilising knowledge holders, and translating and negotiating between differe
Background: Hypertension is the leading modifiable risk factor for cerebral small vessel diseases (SVDs). Yet, it is unknown whether antihypertensive drug classes differentially affect microvascular function in SVDs. Aims: To test whether amlodipine has a beneficial effect on microvascular function when compared to either losartan or atenolol, and whether losartan has a beneficial effect when comp
Despite the importance of mineral-associated organic matter (MAOM) in long-term soil carbon (C) and nitrogen (N) persistence, and the significant contribution of fungal necromass to this pool, the factors controlling the formation of fungal-derived MAOM remain unclear. This study investigated how fungal necromass chemistry, specifically melanin, interacts with soil mineral properties and microbial
This study inventories, classifies, and evaluates the hydrological heritage of North Macedonia, categorizing key features into four main groups: (1) river basins, including rivers and waterfalls; (2) springs, classified as karst and thermal; (3) natural lakes, subdivided into tectonic, glacial, landslide, denudation, and karst types; and (4) marshes. Recent measurements have shown a significant de
The effects of high hydrostatic pressure (up to 8 kbar) on bacteriochlorophyll a Qy electronic absorption bands of LH2 photosynthetic antenna complexes have been studied at ambient temperature. A variety of samples were studied, including intact membranes and isolated complexes from wild type and mutant photosynthetic bacteria Rhodobacter sphaeroides, Rhodopseudomonas acidophila, and Rhodospirillu
Lignocellulosic materials (e.g., straw and bran) are gaining interest as feedstocks for the manufacture of higher value products, recognizing xylooligosaccharides (XOS) as interesting prebiotic compounds, and putting enzymes converting xylooligosaccharides into focus. In this work, we are investigating a XOS converting enzyme from the probiotic bacterium Levilactobacillus brevis (formerly Lactobac
Aims Methadone and buprenorphine diversion by patients in opioid substitution treatment (OST) is a poorly understood phenomenon. We study the norms and attitudes on diversion among OST patients, including the role these norms and attitudes play as diversion risk factors. We also study whether perceived quality of care, social bonds to treatment staff, and deterrence can be associated with diversio
Background: Opioid substitution treatment (OST) with methadone or buprenorphine is the most effective means of treating opioid dependence. If these substances are used by people who are not undergoing OST, they can however carry serious risks. This article examines the lifetime prevalence, motives, and drug sources for such use, as well as geographical differences in these variables. Methods: Stru
Background: Viral infections, including COVID-19, are associated with an increased risk for type 1 diabetes (T1D), but potential underlying mechanisms remain unexplored. We evaluated whether COVID-19 or influenza A infection is characterized by differential DNA methylation at immune and T1D susceptibility genes in young children at risk for T1D. Methods: Epigenome-wide association analysis using t
Gross primary production (GPP) of the vegetation is the largest carbon exchange process of the global carbon cycle. Currently, within satellite-based remote sensing, GPP is generally modelled using linear light use efficiency models where GPP is related to photosynthetically active radiation absorbed by the green vegetation (APAR). These models work well on moderate to low spatiotemporal averaging
The increased demand, driven by a growing population and changing dietary habits, has created immense pressure on agroecosystems throughout the globe. In semi-arid areas, this increased pressure has led to excessive use of agrochemicals in agriculture, which poses a threat of potentially toxic metal (PTM) contamination in agricultural soils. PTMs in agricultural soils result in significant environ
