Diagnosis and management of ST-elevation of myocardial infarction
Reply to Amit Bansal, Ruchir Maheshwari, and Anant Kumar's Letter to the Editor re : Fredrik Liedberg, Petter Kollberg, Marie Allerbo, et al. Preventing Parastomal Hernia After Ileal Conduit by the Use of a Prophylactic Mesh: A Randomised Study. Eur Urol 2020;78:757–63
Percutaneous coronary intervention versus coronary artery bypass grafting in patients with three-vessel or left main coronary artery disease : 10-year follow-up of the multicentre randomised controlled SYNTAX trial
BACKGROUND: The Synergy between PCI with Taxus and Cardiac Surgery (SYNTAX) trial was a non-inferiority trial that compared percutaneous coronary intervention (PCI) using first-generation paclitaxel-eluting stents with coronary artery bypass grafting (CABG) in patients with de-novo three-vessel and left main coronary artery disease, and reported results up to 5 years. We now report 10-year all-cau
Performance of the ATLAS RPC detector and Level-1 muon barrel trigger at √s = 13 TeV
The ATLAS experiment at the Large Hadron Collider (LHC) employs a trigger system consisting of a first-level hardware trigger (L1) and a software-based high-level trigger. The L1 muon trigger system selects muon candidates, assigns them to the correct LHC bunch crossing and classifies them into one of six transverse-momentum threshold classes. The L1 muon trigger system uses resistive-plate chambe
Reassessing the role of type II toxin-antitoxin systems in formation of escherichia coli type II persister cells
Persistence is a reversible and low-frequency phenomenon allowing a subpopulation of a clonal bacterial population to survive antibiotic treatments. Upon removal of the antibiotic, persister cells resume growth and give rise to viable progeny. Type II toxin-antitoxin (TA) systems were assumed to play a key role in the formation of persister cells in Escherichia coli based on the observation that s
Measurement of the very rare K+→π+νν- decay
The NA62 experiment reports the branching ratio measurement BR(K+→π+νν¯)=(10.6−3.4+4.0|stat±0.9syst)×10−11 at 68% CL, based on the observation of 20 signal candidates with an expected background of 7.0 events from the total data sample collected at the CERN SPS during 2016–2018. This provides evidence for the very rare K+→π+νν¯ decay, observed with a significance of 3.4σ. The experiment achieves a
Realeasy: Real-Time capable Simulation to Reality Domain Adaptation
We address the problem of insufficient quality of robot simulators to produce precise sensor readings for joint positions, velocities and torques. Realistic simulations of sensor readings are particularly important for real time robot control laws and for data intensive Reinforcement Learning of robot movements in simulation. We systematically construct two architectures based on Long Short-Term M
Altered Tryptophan Catabolism in Placentas From Women With Pre-eclampsia
Background: The kynurenine pathway enzymes, breaking down tryptophan, are abundant in placental tissue. These metabolites are involved in immunoregulatory mechanisms, although the role of this pathway in pre-eclampsia (PE) has only begun to be characterized. Here, we determined tryptophan and metabolite levels together with the expression of kynurenine pathway enzymes and inflammatory factors in p
Lignin Conversion to Value-Added Small-Molecule Chemicals : Towards Integrated Forest Biorefineries
Lignin is the most abundant aromatic biopolymer on Earth and has significant potential as a feedstock for industrial use. Due to its intrinsic heterogeneity and recalcitrance, lignin has been regarded as a low-value side-product in the pulp and paper industry and in second-generation biorefineries. However, novel technologies are currently being explored to utilize lignin as a renewable resource fo
An evolutionary ratchet leading to loss of elongation factors in eukaryotes
Background: The GTPase eEF1A is the eukaryotic factor responsible for the essential, universal function of aminoacyl-tRNA delivery to the ribosome. Surprisingly, eEF1A is not universally present in eukaryotes, being replaced by the paralog EFL independently in multiple lineages. The driving force behind this unusually frequent replacement is poorly understood. Results: Through sequence searching o
The bacterial toxin RelE induces specific mRNA cleavage in the A site of the eukaryote ribosome
RelE/RelB is a well-characterized toxin-anti-toxin pair involved in nutritional stress responses in Bacteria and Archae. RelE lacks any eukaryote homolog, but we demonstrate here that it efficiently and specifically cleaves mRNA in the A site of the eukaryote ribosome. The cleavage mechanism is similar to that in bacteria, showing the feasibility of A-site cleavage of mRNA for regulatory purposes
Visual attributes of environments : Presentation and judgement of planned environment and the hypothesis of arousal
To find a systematic method for measuring and describing perception of human environment groups of subjects rated various environments with descriptive words, which were given the form of rating scales. Data was processed by means of factor analysis, through which eight main dimensions were obtained. Some of these dimensions were used in an attempt to compare different methods for presentation of
Intergenerational care in corona times: Practices of care in Swedish families during the pandemic
Objective: This paper analyses intergenerational relationships in Sweden during the corona pandemic, with a special focus on practices of care. The research question is: How is care between generations – between grandparents, adult children and grandchildren – done during pandemic conditions? Background: In Sweden, where an extensive welfare state provides affordable child- and eldercare, the coro
Translating polygenic risk scores for clinical use by estimating the confidence bounds of risk prediction
A promise of genomics in precision medicine is to provide individualized genetic risk predictions. Polygenic risk scores (PRS), computed by aggregating effects from many genomic variants, have been developed as a useful tool in complex disease research. However, the application of PRS as a tool for predicting an individual's disease susceptibility in a clinical setting is challenging because PRS t
Women’s work and wages in the sixteenth-century and Sweden’s position in the “Little divergence”
We use a unique source from the Swedish royal demesnes to examine the work and relative wages of women in sixteenth century Sweden, an economic laggard in the Early Modern period. The source pertains to workers hired on yearly contracts, a type more representative for historical labour markets than day-labour on large construction sites, and allows us to observe directly the food consumed by worke
Enhance dune-building processes with nature-based nourishment design
Reply to Holden and Errington, “Type II toxin-antitoxin systems and persister cells”
GTP-dependent structural rearrangement of the eRF1:eRF3 complex and eRF3 sequence motifs essential for PABP binding
Translation termination in eukaryotes is governed by the concerted action of eRF1 and eRF3 factors. eRF1 recognizes the stop codon in the A site of the ribosome and promotes nascent peptide chain release, and the GTPase eRF3 facilitates this peptide release via its interaction with eRF1. In addition to its role in termination, eRF3 is involved in normal and nonsense-mediated mRNA decay through its
Distributed Energy Systems and Energy Communities Under Negotiation
New decentralized energy-generation technologies have turned economies of scale upside down while becoming more economically viable. At the same time, the increased penetration of information technologies has led to new opportunities to manage infrastructure in a less hierarchical, more flexible way. Together with citizen demands for control over energy, these two converging trends has put energy
