Introduction: Motor Imagery (MI) Electroencephalography (EEG) signals are non-stationary and dynamic physiological signals which have low signal-to-noise ratio. Hence, it is difficult to achieve high classification accuracy. Although various machine learning methods have already proven useful to that effect, the use of many features and ineffective EEG channels often leads to a complex structure of classifier algorithms.

Article Synopsis
  • Preeclampsia (PE) is linked to reduced blood flow to the placenta, which can cause heart function changes in pregnant women; this study investigates these cardiac characteristics and their relationship with NT-proBNP levels.
  • A retrospective analysis of 65 PE-diagnosed pregnant women was conducted using echocardiography, revealing normal left ventricular size and function, but impaired longitudinal contractility and borderline left atrial size.
  • Increased NT-proBNP levels were associated with lower gestational age at delivery and were indicative of maternal cardiac changes, with a high preterm birth rate due to worsening PE or fetal health issues linked to placental insufficiency.

Background: It is still unknown if the double-femoral tunnel technique (Arciero [ARC]) provides better stability as compared with the single-femoral tunnel technique (modified Larson [LAR]) in posterolateral corner reconstruction. The ideal angle of fixation of the popliteofibular strand in ARC is also unknown.

Hypotheses: The ARC provides greater external rotation (ER) stability than the LAR (hypothesis 1); there is no difference in varus rotation (VR) stability between LAR and ARC (hypothesis 2); and femoral fixation of the popliteofibular strand at 60° during the ARC leads to greater ER stability than fixation at 30° or 90° of knee flexion (hypothesis 3).

Remission of asthma can occur as part of the natural history of the disease; however, the use of biologics can result in disease remission in some patients. In this post hoc analysis of the RELIght study, we aimed to evaluate clinical remission in real life among patients treated with mepolizumab, to detect possible differences between "remitters" and "nonremitters," and to evaluate possible predictors of remission. Clinical remission was defined as the absence of asthma exacerbations, discontinuation of oral corticosteroids (OCS), achievement of asthma control (Asthma Control Test [ACT] ≥ 20), and stable or improved lung function.

Improving small-scale cultivation of Spodoptera frugiperda 9 cells by silanizing glassware.

Sci Rep

December 2024

Department of Medical Engineering and Biotechnology, Ernst-Abbe-Hochschule, University of Applied Sciences, Carl-Zeiss-Promenade 2, 07745, Jena, Germany.

Cultivating insect cells in glass vessels can be challenging. Due to uncontrolled cell adhesion and associated cell loss as well as clumping, the replication of experiments is put at risk. A cost-effective solution to improve and stabilize cultivation may be to silanize glass vessels, making them more hydrophobic and chemically inert.

Adequate secondary prevention in survivors of intracerebral hemorrhage (ICH) who also have atrial fibrillation (AF) is a long-standing clinical dilemma because these patients are at increased risk of recurrent ICH as well as of ischemic stroke. The efficacy and safety of oral anticoagulation, the standard preventive medication for ischemic stroke patients with AF, in ICH patients with AF are uncertain. PRESTIGE-AF is an international, phase 3b, multi-center, randomized, open, blinded end-point assessment (PROBE) clinical trial that compared the efficacy and safety of direct oral anticoagulants (DOACs) with no DOAC (either no antithrombotic treatment or any antiplatelet drug).

More Than the Sum of Its Parts: Disrupted Core Periphery of Multiplex Brain Networks in Multiple Sclerosis.

Hum Brain Mapp

January 2025

Queen Square Multiple Sclerosis Centre, Department of Neuroinflammation, UCL Queen Square Institute of Neurology, University College London, London, UK.

Disruptions to brain networks, measured using structural (sMRI), diffusion (dMRI), or functional (fMRI) MRI, have been shown in people with multiple sclerosis (PwMS), highlighting the relevance of regions in the core of the connectome but yielding mixed results depending on the studied connectivity domain. Using a multilayer network approach, we integrated these three modalities to portray an enriched representation of the brain's core-periphery organization and explore its alterations in PwMS. In this retrospective cross-sectional study, we selected PwMS and healthy controls with complete multimodal brain MRI acquisitions from 13 European centers within the MAGNIMS network.

Imaged capillary isoelectric focusing was successfully applied for separating an in-house synthesized closely related peptide pair, that is, a linear 12-mer (Rp5-L) and its cyclic 15-mer variant (Rp5-C). Rp5-L represents a mimotope, that is, an epitope mimicking peptide, of the CD20 antigen, which is over-expressed in B-cell-related tumors. Peptide identity-including the successful disulfide bond formation in Rp5-C-was confirmed with matrix-assisted laser desorption ionization-time of flight mass spectrometry.

Naturally occurring fragments of collagen type I alpha 1 chain (COL1A1) have been previously associated with chronic kidney disease (CKD), with some fragments showing positive and others negative associations. Using urinary peptidome data from healthy individuals (n = 1131) and CKD patients (n = 5585) this aspect was investigated in detail. Based on the hypothesis that many collagen peptides are derived not from the full, mature collagen molecule, but from (larger) collagen degradation products, relationships between COL1A1 peptides containing identical sequences were investigated, with the smaller (offspring) peptide being a possible degradation product of the larger (parent) one.
