Single-Molecule Magnets DyM2N@C80and Dy2MN@C80(M=Sc, Lu): The Impact of Diamagnetic Metals on Dy3++Magnetic Anisotropy, Dy···Dy Coupling, and Mixing of Molecular and Lattice Vibrations
The substitution of scandium in fullerene single‐molecule magnets (SMMs) DySc2N@C80 and Dy2ScN@C80 by lutetium has been studied to explore the influence of the diamagnetic metal on the SMM performance of dysprosium nitride clusterfullerenes. The use of lutetium led to an improved SMM performance of DyLu2N@C80, which shows a higher blocking temperature of magnetization (TB=9.5 K), longer relaxation
The properties of α-synuclein secondary nuclei are dominated by the solution conditions rather than the seed fibril strain
Amyloid fibrils of α-synuclein (α-syn) are a component of Lewy bodies, the characteristic hallmark of Parkinson's disease. Amyloid fibrils arise through primary nucleation from monomers, which in the case of α-syn is often heterogeneous, followed by the growth of the nuclei by monomer addition. Secondary nucleation corresponds to the formation of new fibrils facilitated by pre-existing fibrils. Wh
Difficult birth is the main contributor to birth-related fracture and accidents to other neonatal fractures
Aim: Specific birth-related fractures have been studied; underestimates might be a problem. We aimed to assess all fractures diagnosed as birth-related as well as other neonatal fractures. Methods: A population-based study on all infants born in Sweden 1997-2014; data were retrieved from the Swedish Health Registers (10th version of International Classification of Diseases. Outcome measures were b
Active chest tube clearance after aortic valve surgery did not influence amount residual pericardial fluid after aortic valve replacement in a randomised trial
Objective. Evaluate if the use of active clearance of chest tubes after aortic valve surgery influenced bleeding and reduced postoperative residual pericardial effusion. Design. Prospective randomised trial comparing PleuraFlow® 32 F chest tube with FlowGlide™ active clearance to a standard Argyle® 32 F chest tube in 100 patients undergoing aortic valve surgery. Chest tube outputs and pericardial
A field evaluation of long-term effects of PIT tagging
Passive integrated transponder (PIT)-tagging is commonly used in behavioural studies of fish, although long-term evaluations of effects from tagging under natural conditions are scarce. We PIT-tagged common bream Abramis brama, European perch Perca fluviatilis, pike Esox lucius and roach Rutilus rutilus, released them in their lakes of origin and recaptured them after 103–3269 days. Overall, tagge
Fracture risk after three bariatric surgery procedures in Swedish obese subjects : up to 26 years follow-up of a controlled intervention study
Background: Previous studies have reported an increased fracture risk after bariatric surgery. Objective: To investigate the association between different bariatric surgery procedures and fracture risk. Methods: Incidence rates and hazard ratios for fracture events were analysed in the Swedish Obese Subjects study; an ongoing, nonrandomized, prospective, controlled intervention study. Hazard ratio
Pressurized carbon dioxide as a potential tool for decellularization of pulmonary arteries for transplant purposes
Vascular bio-scaffolds produced from decellularized tissue offer a promising material for treatment of several types of cardiovascular diseases. These materials have the potential to maintain the functional properties of the extracellular matrix (ECM), and allow for growth and remodeling in vivo. The most commonly used methods for decellularization are based on chemicals and enzymes combinations,
Comparative effectiveness of abatacept, rituximab, tocilizumab and TNFi biologics in RA : Results from the nationwide Swedish register
Objectives: Current guidelines rank abatacept, rituximab, tocilizumab and TNF-inhibitors (TNFi) as having equal effectiveness for the treatment of RA, at least as second line therapies. These recommendations are mainly based on meta-analysis of randomized controlled trials, with few direct drug-drug comparisons. Our objective was to compare the real-world absolute and relative effectiveness among
Selective attention in visual short-term memory consolidation
Selection of visual short-term memory content takes place during perceptual and postperceptual processing. We studied postperceptual selection in a change detection task, in which spatially distributed cues preceding the memory array marked potential change targets. In the 550-730ms interval after the memory array onset but not in the following retention interval, event-related potentials showed l
Breastfeeding as a balancing act - Pregnant Swedish women's voices on breastfeeding
Background: Breastfeeding provides health benefits to both women and children. The rationale behind an individual woman's decision to breastfeed or not can depend on several factors, either independently or in combination. The aim of the current study was to explore attitudes towards breastfeeding among pregnant women in Sweden who intend to breastfeed. Methods: Eleven mothers-to-be, one of whom h
Transcriptomic landscape of the blastema niche in regenerating adult axolotl limbs at single-cell resolution
Regeneration of complex multi-tissue structures, such as limbs, requires the coordinated effort of multiple cell types. In axolotl limb regeneration, the wound epidermis and blastema have been extensively studied via histology, grafting, and bulk-tissue RNA-sequencing. However, defining the contributions of these tissues is hindered due to limited information regarding the molecular identity of th
Letter to editor regarding Kotta et al. 2020 : Cleaning up seas using blue growth initiatives: Mussel farming for eutrophication control in the Baltic Sea
Triple visual hemifield maps in a case of optic chiasm hypoplasia
In humans, each hemisphere comprises an overlay of two visuotopic maps of the contralateral visual field, one from each eye. Is the capacity of the visual cortex limited to these two maps or are plastic mechanisms available to host more maps? We determined the cortical organization of the visual field maps in a rare individual with chiasma hypoplasia, where visual cortex plasticity is challenged t
Safeguarding of quinoa beverage production by fermentation with Lactobacillus plantarum DSM 9843
Plant-based beverages are increasing in popularity and quinoa is an attractive option. A hygienic implication linked to the production of beverages from raw material originating from plants is the high microbial contamination. The safety of the product can be guaranteed by lactic acid fermentation, and by using a probiotic strain as starter culture for the fermentation, the final product will bene
A novel technique for detailed and time-efficient combustion modeling of fumigated dual-fuel internal combustion engines
The present work details a study of the 3D-modeling of dual-fuel engines, with a specific focus on medium speed marine engines. These operate under the fumigated approach, which means that the second fuel, which replaces most of the diesel fuel, is added in the intake duct. This type of engine requires the least amount of modifications to the current medium speed diesel engine and is therefore an
Clinical characteristics distinguishing tramadol-using adolescents from other substance-using adolescents in an out-patient treatment setting
Background: Non-medical Prescription Opioid Use (NMPOU) has increased worldwide during the last decades, and specifically, tramadol misuse may represent a novel pattern of substance use among adolescents. The present study aims to analyze characteristics distinguishing tramadol-using adolescents from other substance-using adolescents seeking out-patient treatment. Methods: This is a cross-sectiona
Endogenous Programs and Flexibility in Bird Migration
Endogenous programs that regulate annual cycles have been shown for many taxa, including protists, arthropods, fish, mammals and birds. In migration biology, these programs are best known in songbirds. The majority of songbirds rely on a genetic program inherited from their parents that will guide them during their first solo-migration. The phenotypic components of the program are crucial for thei
