Accuracy and precision in super-resolution MRI : Enabling spherical tensor diffusion encoding at ultra-high b-values and high resolution

Diffusion MRI (dMRI) can probe the tissue microstructure but suffers from low signal-to-noise ratio (SNR) whenever high resolution is combined with high diffusion encoding strengths. Low SNR leads to poor precision as well as poor accuracy of the diffusion-weighted signal; the latter is caused by the rectified noise floor and can be observed as a positive bias in magnitude signal. Super-resolution

Timing in Purkinje Cells and a Novel Learning Mechanism

During eyeblink conditioning, Purkinje cells that control the eyelid learn to respond with a pause in simple spike firing to the conditional stimulus. This conditional pause response (CR) in the Purkinje cell is adaptively timed and drives the overt response. Recent results show that the Purkinje cell CR does not depend on modification of synaptic strength such as long-term depression but on a nov

Epidemiology of clubfoot in Sweden from 2016 to 2019 : A national register study

BACKGROUND: This study aimed to estimate the birth prevalence of children born with isolated or non-isolated clubfoot in Sweden using a national clubfoot register. Secondarily we aimed to describe the clubfoot population with respect to sex, laterality, severity of deformity, comorbidity and geographic location.METHODS: A national register, the Swedish Pediatric Orthopedic Quality register, was us

Copeptin as a marker of atherosclerosis and arteriosclerosis

Background and aims: The precursor peptide of vasopressin, copeptin, has previously been linked to increased risk of developing diabetes mellitus, coronary artery disease and cardiovascular mortality. Whether elevated copeptin is associated with markers of atherosclerosis and arteriosclerosis in the general population is not known. Methods: In this population-based, cross-sectional study, coronary

CellexalVR : A virtual reality platform to visualize and analyze single-cell omics data

Single-cell RNAseq is a routinely used method to explore heterogeneity within cell populations. Data from these experiments are often visualized using dimension reduction methods such as UMAP and tSNE, where each cell is projected in two or three dimensional space. Three-dimensional projections can be more informative for larger and complex datasets because they are less prone to merging and flatt

Structure-Guided Design of d -Galactal Derivatives with High Affinity and Selectivity for the Galectin-8 N-Terminal Domain

Galectin-8 is a carbohydrate-binding protein that plays a crucial role in tumor progression and metastasis, antibacterial autophagy, modulation of the immune system, and bone remodeling. The design, synthesis, and protein affinity evaluation of a set of C-3 substituted benzimidazole and quinoline d-galactal derivatives identified a d-galactal-benzimidazole hybrid as a selective ligand for the gale

Non-corticosteroid adjuvant therapies for acute bacterial meningitis

Background: Acute bacterial meningitis is a bacterial infection of the membranes that surround and protect the brain, known as the meninges. The primary therapy for bacterial meningitis is antibiotics and corticosteroids. Although these therapies significantly improve outcomes, bacterial meningitis still has a high risk of death and a high risk of neurological sequelae in survivors. New adjuvant t

Guided internet-delivered cognitive behavior therapy for post-traumatic stress disorder: a randomized controlled trial.

The aim of this randomized controlled trial was to investigate the effects of guided internet-based cognitive be-havior therapy (ICBT) for posttraumatic stress disorder (PTSD). Sixty-two participants with chronic PTSD, asassessed by the Clinician-administered PTSD Scale, were recruited via nationwide advertising and randomizedto either treatment (n= 31) or delayed treatment attention control (n= 3

Blood-based mitochondrial respiratory chain function in major depression

Mitochondrial dysfunction has been implicated in major depressive disorder (MDD). A measure of mitochondrial respiratory chain (RC) enzymatic activity—the Mitochondrial Health Index (MHI)—has previously been found to correlate with stress and emotional states in caregivers. We here report mitochondrial RC activities, mitochondrial DNA copy number (mtDNAcn), and the composite MHI in unmedicated and

Evidence of support used for drug treatments in pediatric cardiology

Background and aims: Clinical support systems are widely used in pediatric care. The aim of this study was to assess the support for drug treatments used at pediatric cardiac wards and intensive care units in Sweden. Methods: Drug information, such as type of drug, indication, dose, and route of administration, for all in-hospital pediatric cardiac patients, was included in the study. Treatments w

Online Copyright Infringement and Enforcement in Sweden

Report on online copyright infringement and enforcement of rights in Sweden. Includes a description of applicable law and current practices. Part of Annex 2 in Quintais, J.P. Global Online Piracy Study: Legal Background Report, Institute of Information Law, University of Amsterdam, 2018 .

Should the use of DRM systems to protect lawful consumption of digital works remain absolute in scope? : TILTing perspectives 2017 Regulating a connected world, 17-19 May 2017, Tilburg, Netherlands

From a strict technological perspective copyright holders can today truly enforce their rights ex ante by creating closed environments in which the consumption of digital works is strictly controlled by DRM systems. The scope of such control is however usually attributable to a given business model rather than legal compliance because the copyright framework (and particularly Art. 6 InfoSoc Direct

Clinical Usefulness of Retropulsion Tests in Persons with Mild to Moderate Parkinson’s Disease

People with Parkinson’s disease (PwPD) have an increased risk for falls and near falls. They have particular difficulties with maintaining balance against an external perturbation, and several retropulsion tests exist. The Unified PD Rating Scale item 30 (UPDRS30) is the most common, involving an expected shoulder pull. Others recommend using an unexpected shoulder pull, e.g., the Nutt Retropulsio

Trends in remote health care consumption in Sweden : A comparison before and during the first wave of the Covid-19 pandemic

BACKGROUND: Remote assessment of respiratory tract infections (RTIs) has been a controversial topic during the fast development of private telemedicine providers in Swedish primary health care. The possibility to unburden the traditional care has been put against a questionable quality of care as well as risks of increased utilization and costs. The covid-19 pandemic has contributed to a changed m

People making things happen : Visiting the inter-action of lifestyle enterprising

This paper engages with the micro action of lifestyle enterprising from an interactionist perspective. The here-and-now action of enterprising is examined in the using the microsociology of Erving Goffman in a single observational case study of tourism lifestyle enterprising in Sweden. The findings illustrate the blurring of assorted personal and commercial domains in the performance of enterprisi

Perceived Stress, Psychological Resources and Salivary Cortisol

The aim of this chapter was to analyze associations between measures of cortisol in saliva withmeasures of perceived stress, using the Perceived Stress Scale (PSS), and of psychological resources interms of mastery, locus of control, self-esteem and sense of coherence. Only studies on healthy individualswere included and cortisol measures were grouped into single time point measures, deviation mea

Retinal indoleamine accumulating neurons

A previously unknown set of neurons, characterized by their ability to accumulate indoleamines, has been identified in the retina of Cebus monkeys, rabbits, cats, pigeons, chicken, goldfish and lampreys. They are not demonstrable with presently available techniques in humans, Cynomolgus monkeys, cows, pigs and rats. The neurons are called indoleamine accumulating neuron and form a subset of amacri

Combined presentation and immunogenicity analysis reveals a recurrent RAS.Q61K neoantigen in melanoma

Neoantigens are now recognized drivers of the antitumor immune response. Recurrent neoantigens, shared among groups of patients, have thus become increasingly coveted therapeutic targets. Here, we report on the data-driven identification of a robustly presented, immunogenic neoantigen that is derived from the combination of HLA-A*01:01 and RAS.Q61K. Analysis of large patient cohorts indicated that
