Reducing bias in dual flip angle T1-mapping in human brain at 7T

Purpose: To address the systematic bias in whole-brain dual flip angle (DFA) T1-mapping at7T by optimizing the flip angle pair and carefully selecting RF pulse shape and duration.Theory and Methods: Spoiled gradient echoes can be used to estimate whole-brain maps ofT1. This can be accomplished by using only two acquisitions with different flip angles, i.e., aDFA-based approach.

Lifestyle factors and risk of multimorbidity of cancer and cardiometabolic diseases : a multinational cohort study

BACKGROUND: Although lifestyle factors have been studied in relation to individual non-communicable diseases (NCDs), their association with development of a subsequent NCD, defined as multimorbidity, has been scarcely investigated. The aim of this study was to investigate associations between five lifestyle factors and incident multimorbidity of cancer and cardiometabolic diseases. METHODS: In thi

Third-trimester prediction of successful vaginal birth after one cesarean delivery—A Swedish model

Introduction: The objective was to create a clinically useful prediction model for vaginal birth in trial of labor after one cesarean section, appropriate for a third trimester consultation. Material and methods: Women with one cesarean section and at least one following delivery (N = 38 686) in the Swedish Medical Birth Register, 1998-2013, were studied. The women were randomly divided into one d

A novel CCA attack using decryption errors against LAC

Cryptosystems based on Learning with Errors or related problems are central topics in recent cryptographic research. One main witness to this is the NIST Post-Quantum Cryptography Standardization effort. Many submitted proposals rely on problems related to Learning with Errors. Such schemes often include the possibility of decryption errors with some very small probability. Some of them have a som

Coronary artery perforation and tamponade : Incidence, risk factors, predictors and outcomes from 12 years' data of the SCAAR registry

Background: The incidence and short- and long-term outcomes of coronary artery perforation (CAP) are not well described. Methods and Results: We analyzed the characteristics and the short- and long-term outcomes of CAP among 243,149 patients undergoing percutaneous coronary interventions (PCI) from 2005 until 2017 in the national Swedish registry. We identified 1,008 cases of CAP with an incidence

Hsp70 (HSPA1) Lysine Methylation Status as a Potential Prognostic Factor in Metastatic High-Grade Serous Carcinoma

Cellular proteins are subject to frequent methylation on lysine residues, introduced by specific methyltransferases, and each lysine residue can receive up to three methyl groups. Histone methylations, which are key determinants of chromatin state and transcriptional status, have been subject to particularly intense studies, but methylations on non-histone protein substrates are also abundant and

Spelmanslag för integration – svensk folkmusik, El Sistema och ”kulturell allemansrätt"

I Malmö startade El Sistema 2013 i två skolor i Holma och Kroksbäck, områden där 33% av invånarna är födda utomlands. Initiativet var ett led i att skydda ”den kulturella allmansrätten” (Lorensson, 2013) för alla och att på längre sikt inkludera fler stadsdelar. Det skulle snart stå tydligt att de omsorgsfullt valda sex musiklärarna hade fått en balansakt att manövrera: dels är de konstnärliga mål

Accumulated neighbourhood deprivation and coronary heart disease : A nationwide cohort study from Sweden

Objective Neighbourhood deprivation is a recognised predictor of coronary heart disease (CHD). The overall aim was to investigate if accumulated exposure to neighbourhood deprivation resulted in higher odds of CHD. Design This is a longitudinal cohort study. Models based on repeated assessments of neighbourhood deprivation as well as single-point-in-time assessments were compared. Setting Sweden.

Endo-lysosomal proteins and ubiquitin CSF concentrations in Alzheimer's and Parkinson's disease

Background: Increasing evidence implicates dysfunctional proteostasis and the involvement of the autophagic and endo-lysosomal system and the ubiquitin-proteasome system in neurodegenerative diseases. In Alzheimer's disease (AD), there is an accumulation of autophagic vacuoles within the neurons. In Parkinson's disease (PD), susceptibility has been linked to genes encoding proteins involved in aut

Lawrence Summers Deserves a Nobel Prize for Reviving the Theory of Secular Stagnation

Lawrence Summers produced a big upset within the economics profession when he revived Alvin Hansen’s theory of secular stagnation, which had been thought of as an old-Keynesian fallacy. While some economists like Brad DeLong and Paul Krugman instantly recognized Summers’s contribution, a large share of the economics profession remained skeptical at first. Whereas most New Keynesian models allow fo

Alignment limit in three Higgs-doublet models

The LHC Higgs data are showing a gradual inclination towards the standard model (SM) result, and realization of a SM-like limit becomes essential for beyond the SM scenarios to survive. Considering the accuracy that can be achieved in future colliders, models beyond the standard model that acquire the alignment limit with a SM-like Higgs boson can surpass others in the long run. Using a convenient

The Miaolingian, a new name for the ‘Middle’ Cambrian (Cambrian Series 3) : identification of lower and upper boundaries in Baltoscandia

The Miaolingian is the new formal name for Cambrian Series 3 (≈ “Middle” Cambrian). The Global Stratotype Section and Point (GSSP) is defined in the Kaili Formation, Guizhou province, China, and is correlated by the First appearance Datum (FAD) of the trilobite Oryctocephalus indicus. However, this fossil has not been recorded from Baltoscandia. Here acritarchs may be used for identifying the base

Importance of leaf litter fragmentation for bacterial growth

Four fragment size groups of maple leaf litter (Acer platanoides) were leached with sterile water. The fragments and leachates were inoculated with bacteria isolated from maple leaf litter and bacterial activity and growth were determined. About 80-90% of the dissolved organic carbon (DOC) released from the leaf fragments was released during the 1st day; the release was negatively correlated with
