A Tissue-Mapped Axolotl De Novo Transcriptome Enables Identification of Limb Regeneration Factors

Mammals have extremely limited regenerative capabilities; however, axolotls are profoundly regenerative and can replace entire limbs. The mechanisms underlying limb regeneration remain poorly understood, partly because the enormous and incompletely sequenced genomes of axolotls have hindered the study of genes facilitating regeneration. We assembled and annotated a de novo transcriptome using RNA-

Performance improvement of automated melanoma diagnosis system by data augmentation

Color information is an important tool for diagnosing melanoma. In this study, we used a hyper-spectral imager (HSI), which can measure color information in detail, to develop an automated melanoma diagnosis system. In recent years, the effectiveness of deep learning has become more widely accepted in the field of image recognition. We therefore integrated the deep convolutional neural network wit

Non-resonant Raman scattering of wurtzite GaAs and InP nanowires

It is now possible to synthesize the wurtzite crystal phase of most III-V semiconductors in the form of nanowires. This sparks interest for fundamental research and adds extra degrees of freedom for designing novel devices. However, the understanding of many properties, such as phonon dispersion, of these wurtzite semiconductors is not yet complete, despite the extensive number of studies publishe

Internal Market Acquis as a Tool in EU External Relations: From Integration to Disintegration

Brexit and the ensuing uncertainty about the United Kingdom’s (UK’s) future relationship with the European Union (EU) have brought the participation of non-EU Member States in the internal market to the centre of academic attention. The latter phenomenon is not novel and many of the existing frameworks for cooperation between the EU and its neighbourhood countries have been used as models for a po

For love and for life: emotional dynamics at the World Congress of Families

The article explores the relationship between emotions, collective identity and mobilisation in conservative social movements through an analysis of the World Congress of Families’ (WCF) 13th international conference, held in Verona in March 2019. WCF promotes Christian family values and brings together anti-gay, anti-feminist and anti-abortion activists, religious leaders, and politicians from ar

Genome-wide association meta-analyses combining multiple risk phenotypes provide insights into the genetic architecture of cutaneous melanoma susceptibility

Most genetic susceptibility to cutaneous melanoma remains to be discovered. Meta-analysis genome-wide association study (GWAS) of 36,760 cases of melanoma (67% newly genotyped) and 375,188 controls identified 54 significant (P < 5 × 10-8) loci with 68 independent single nucleotide polymorphisms. Analysis of risk estimates across geographical regions and host factors suggests the acral melanoma sub

Host dispersal shapes the population structure of a tick-borne bacterial pathogen

Birds are hosts for several zoonotic pathogens. Because of their high mobility, especially of longdistance migrants, birds can disperse these pathogens, affecting their distribution and phylogeography. We focused on Borrelia burgdorferi sensu lato, which includes the causative agents of Lyme borreliosis, as an example for tick-borne pathogens, to address the role of birds as propagation hosts of z

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
