Background Symptomatic acute occlusions of the internal carotid artery (ICA) below the circle of Willis can cause a variety of stroke symptoms, even if the major intracranial cerebral arteries remain patent; however, outcome and safety data are limited. Purpose To compare treatment effects and procedural safety of endovascular treatment (EVT) and best medical treatment (BMT) in patients with symptomatic acute occlusions of the ICA below the circle of Willis. Materials and Methods This retrospective, multicenter cohort study from 22 comprehensive stroke centers in Europe and Asia includes patients treated between January 1, 2008, and December 31, 2022.

Characterization of a simple gas expansion ion source for intense pulses of subthermal molecular ions.

Rev Sci Instrum

January 2025

Max-Planck-Institut für Kernphysik, Saupfercheckweg 1, 69117 Heidelberg, Germany.

We describe a simple gas expansion ion source based on static discharge voltages and a commercially available pulsed valve. The discharge is initiated by the gas pulse itself between two high voltage electrodes, without the need for fast voltage switches or complex timing schemes. The ion source very reliably produces intense bursts of molecular ions (with currents exceeding 100 μA during the pulse-on phase) with only minor pulse-to-pulse variations in intensity and pulse shape.

An accurate diagnosis of invasive aspergillosis (IA) in patients with underlying hematological malignancies relies heavily on galactomannan detection. In this study, we compared the VirCLIA chemiluminescence immunoassay (CLIA) with the frequently used Platelia enzyme-linked immunosorbent assay (ELISA) on serum from hematology patients with suspected IA. Patients were categorized according to EORTC/MSGERC 2020 definitions into proven/probable IA and possible/no IA.

Background: Brain-gut behaviour therapies (BGBT) have gained widespread acceptance as therapeutic modalities for the management of disorders of gut-brain interaction (DGBI). However, existing treatment evaluation methods in the medical field fail to capture the specific elements of scientific rigour unique to behavioural trial evaluation.

Aims: To offer the first consensus on the development and testing of BGBT in DGBI.

Université libre de Bruxelles (ULB), UNI - ULB Neuroscience Institute, Laboratoire de Neuroanatomie et Neuroimagerie translationnelles (LN2T), Brussels, Belgium.

Language control processes allow for the flexible manipulation and access to context-appropriate verbal representations. Functional magnetic resonance imaging (fMRI) studies have localized the brain regions involved in language control processes usually by comparing high vs. low lexical-semantic control conditions during verbal tasks.

Exploring the Impact of Declarative Learning on the Consolidation of Acquired Motor Skills Under Valence Feedback.

Hum Brain Mapp

February 2025

Neuroscience and Neuroengineering Research Laboratory, Biomedical Engineering Department, School of Electrical Engineering, Iran University of Science and Technology (IUST), Tehran, Iran.

Implicit motor learning involves the acquisition and consolidation of motor skills without conscious awareness, influenced by various factors. Punishment and reward have been identified as significant modulators during training, impacting skill acquisition differently. Additionally, the role of a second declarative task in offline consolidation has been explored, affecting both stabilization and enhancement processes during wake and sleep periods.

The discovery that infections of viruses are pervasive among insects has considerable potential for future applications, such as new strategies for pest control through the manipulation of virus-host interactions. However, few studies can be found that aim to minimize (for beneficial insects) or maximize (for pests) virus impact or virulence. Viruses generally employ molecular mechanisms that deviate from the cells' to increase their replication efficiency and to avoid the immune response.

Determining the harvest location of timber is crucial to enforcing international regulations designed to protect natural resources and to tackle illegal logging and associated trade in forest products. Stable isotope ratio analysis (SIRA) can be used to verify claims of timber harvest location by matching levels of naturally occurring stable isotopes within wood tissue to location-specific ratios predicted from reference data ("isoscapes"). However, overly simple models for predicting isoscapes have so far limited the confidence in derived predictions of timber provenance.

Background And Purpose: Prolonged length of stay (LOS) following a stroke is associated with unfavorable clinical outcomes. Factors predicting LOS in medium vessel occlusion (MeVO), impacting up to 40% of acute ischemic stroke (AIS) cases, remain underexplored. This study aims to investigate the predictors of LOS in AIS-MeVO.

Unlabelled: In this unblinded multi-center stepped-wedge randomized controlled trial the effectiveness of the nurse-led ZENN-intervention was tested in promoting self-management skills in comparison to standard care among heart, lung and kidney transplant recipients. This intervention is based on behaviour change theories and was conducted in four sessions over 6 months at the outpatient clinic. The experimental group received standard care, plus the ZENN-intervention, while the control group received only standard care.

Microvascular inflammation (MVI) in kidney transplant biopsies is mainly associated with antibody-mediated rejection (AMR), sparking debate within the Banff Classification of Renal Allograft Pathology regarding its exclusivity. This study reviewed the literature on MVI in T cell-mediated rejection (TCMR) and analyzed MVI in our transplant population. We searched English publications in MEDLINE, Embase, Web of Science, Cochrane, and Google Scholar until June 2024, focusing on glomerulitis (g), peritubular capillaritis (ptc), or MVI in kidney transplant biopsies classified as TCMR.

Metagenomics-based tracing of genetically modified microorganism contaminations in commercial fermentation products.

Food Chem (Oxf)

June 2025

Sciensano, Transversal activities in Applied Genomics (TAG), J. Wytsmanstraat 14, 1050 Brussels, Belgium.

Genetically modified microorganisms (GMM) are frequently employed for the production of microbial fermentation products such as food enzymes. Although presence of the GMM or its recombinant DNA in the final product is not authorized, contaminations occur frequently. Insight into the contamination source of a GMM is of crucial importance to allow the competent authorities to take appropriate action.

Background: Despite a wide range of available treatments, there is limited evidence as to why significant numbers of Crohn's disease (CD) patients do not achieve disease remission or continue to have residual symptom burden. We aimed to quantify the impact of this suboptimal treatment on patient symptom incidence and severity, quality of life (QoL), and work impairment.

Methods: Data were derived from the Adelphi Real World CD Disease Specific Programme, a cross-sectional survey of CD patients and their treating physicians in France, Germany, Italy, Spain, the United Kingdom, and the United States between January 2020 and March 2021.
