Kinetics of the West Nile virus induced transcripts of selected cytokines and Toll-like receptors in equine peripheral blood mononuclear cells

Muhammad Jasim Uddin, Willy W. Suen, Angela M. Bosco‐Lauth et al. · 2016 · Veterinary Research

West Nile virus (WNV) is one of the most common causes of epidemic viral encephalitis in horses worldwide. Peripheral blood mononuclear cells (PBMCs) are amongst the first to encounter the virus following a mosquito bite. This study aimed to elucidate the transcription kinetics of cytokine, Toll-like receptor (TLRs) and TLRs-associated genes following WNV challenge of equine PBMCs. PBMCs were challenged with an Australian strain of WNV (WNVNSW2011) and transcriptomes were quantified at 2, 6, 12 and 24 h post-infection (pi) using qRT-PCR. Type I and II interferons (IFNα, β and γ) mRNA transcrip

Detection of Two Highly Diverse Peribunyaviruses in Mosquitoes from Palenque, Mexico

Anne Kopp, Alexandra Hübner, Florian Zirkel et al. · 2019 · Viruses

. Orthobunyaviruses and pacuviruses are mainly transmitted by blood-feeding insects and infect a variety of vertebrates whereas herbeviruses and shangaviruses have a host range restricted to insects. Here, we tested mosquitoes from a tropical rainforest in Mexico for infections with peribunyaviruses. We identified and characterized two previously unknown viruses, designated Baakal virus (BKAV) and Lakamha virus (LAKV). Sequencing and de novo assembly of the entire BKAV and LAKV genomes revealed that BKAV is an orthobunyavirus and LAKV is likely to belong to a new genus. LAKV was almost equidis

BMI variability and cardiovascular outcomes within clinical trial and real-world environments in type 2 diabetes: an IMI2 SOPHIA study

Robert Massey, Yu Chen, Marina Panova‐Noeva et al. · 2024 · Cardiovascular Diabetology

BACKGROUND: BMI variability has been associated with increased cardiovascular disease risk in individuals with type 2 diabetes, however comparison between clinical studies and real-world observational evidence has been lacking. Furthermore, it is not known whether BMI variability has an effect independent of HbA1c variability. METHODS: We investigated the association between BMI variability and 3P-MACE risk in the Harmony Outcomes trial (n = 9198), and further analysed placebo arms of REWIND (n = 4440) and EMPA-REG OUTCOME (n = 2333) trials, followed by real-world data from the Tayside Bioreso

4-Aminobutyrate Aminotransferase (ABAT): Genetic and Pharmacological Evidence for an Involvement in Gastro Esophageal Reflux Disease

Johan Jirholt, Bengt Åsling, Paul Hammond et al. · 2011 · PLoS ONE

Gastro-esophageal reflux disease (GERD) is partly caused by genetic factors. The underlying susceptibility genes are currently unknown, with the exception of COL3A1. We used three independent GERD patient cohorts to identify GERD susceptibility genes. Thirty-six families, demonstrating dominant transmission of GERD were subjected to whole genome microsatellite genotyping and linkage analysis. Five linked regions were identified. Two families shared a linked region (LOD 3.9 and 2.0) on chromosome 16. We used two additional independent GERD patient cohorts, one consisting of 219 trios (affected

Data-driven profiles of attention-deficit/hyperactivity disorder using objective and ecological measures of attention, distractibility, and hyperactivity

Pilar Fernández‐Martín, Rocío Rodríguez‐Herrera, Rosa Cánovas et al. · 2023 · European Child & Adolescent Psychiatry

In the past two decades, the traditional nosology of attention-deficit/hyperactivity disorder (ADHD) has been criticized for having insufficient discriminant validity. In line with current trends, in the present study, we combined a data-driven approach with the advantages of virtual reality aiming to identify novel behavioral profiles of ADHD based on ecological and performance-based measures of inattention, impulsivity, and hyperactivity. One hundred and ten Spanish-speaking participants (6-16 years) with ADHD (medication-naïve, n = 57) and typically developing participants (n = 53) complete

Bidirectional Associations of Adolescents’ Momentary Social Media Use and Negative Emotions

Tyler Colasante, Katie Faulkner, Dana Kharbotli et al. · 2024 · Affective Science

Abstract Public discourse and empirical studies have predominantly focused on the negative repercussions of social media on adolescents’ mental health. However, pervasive social media use is a relatively new phenomenon—its apparent harms have been widely accepted before sufficient longitudinal and experimental research has been conducted. The present study used an intensive longitudinal design (four assessments/day × 14 days; N = 154 12- to 15-year-olds ( M age = 13.47, SD = 0.58); N = 6,240 valid measurement occasions) to test the directionality of social media–negative emotion links in early

Communicating Evidence about the Causes of Obesity and Support for Obesity Policies: Two Population-Based Survey Experiments

James P. Reynolds, Milica Vasiljevic, Mark Pilling et al. · 2020 · International Journal of Environmental Research and Public Health

Public support for numerous obesity policies is low, which is one barrier to their implementation. One reason for this low support is the tendency to ascribe obesity to failings of willpower as opposed to the environment. Correlational evidence supports this position. However, the experimental evidence is mixed. In two experimental studies, participants were randomised to receive no message, messages about the environment’s influence on obesity (Study 1 & 2), or messages about the environment’s influence on human behaviour (Study 1). We investigated whether communicating these messages cha

Large-scale multi-omics unveils host–microbiome interactions driving root development and nitrogen acquisition

Nannan Li, Guoliang Li, Xiaofang Huang et al. · 2026 · Nature Plants

The rhizosphere microbiome plays a crucial role in determining plant performance and fitness. Nevertheless, regulatory mechanisms linking host genetic variation, root gene regulation and microbiome assembly-and their collective influence on plant nutritional traits-remain poorly understood. Here we generated and integrated 1,341 paired datasets, including root transcriptomes, rhizosphere bacterial 16S rRNA profiles and root ionomes, across 175 resequenced Brassica napus ecotypes grown at two contrasting field sites. We identified 203 highly heritable bacterial amplicon sequence variants (ASVs)

The self-assembly of glycyrrhizic acid into nanofibrils

Suelen Gauna Trindade, Fernando Bonin Okasaki, Ashley P. Williams et al. · 2025 · Journal of Colloid and Interface Science

The self-assembly of glycyrrhizic acid (GA) in aqueous solutions has significant implications for soft matter science and material design. Here, we describe the self-assembly of GA under well-defined conditions, focusing on measurements of the critical aggregation concentration (CAC) - when GA dimers start stacking into nanofibrils, and of the critical gel concentration (CGC) - when nanofibrils entangle into a viscoelastic network. We examine in detail the structure at low concentrations and its evolution into a viscoelastic hydrogel, addressing the kinetic pathway. We highlight the dependence

TREM2 expression level is critical for microglial state, metabolic capacity and efficacy of TREM2 agonism

Astrid Feiten, Kilian Dahm, Kai Schlepckow et al. · 2026 · Nature Communications

Triggering receptor expressed on myeloid cells 2 (TREM2) is a central regulator of microglial activity and loss-of-function coding variants are major risk factors for late onset Alzheimer's disease (LOAD). To better understand the molecular and functional changes associated with TREM2 signalling in microglia, we generated a TREM2 reporter mouse. In APP transgenic animals, bulk RNA-sequencing of isolated microglia sorted based on reporter expression highlighted TREM2 level-related changes in major immunometabolic pathways, and enrichment of genes in oxidative phosphorylation and cholesterol met

Using Solid-State NMR to Understand the Structure of Plant Cellulose

Rosalie Cresswell, Parveen Kumar Deralia, Yoshihisa Yoshimi et al. · 2025 · Journal of the American Chemical Society

High Resolution Image Download MS PowerPoint Slide The structure of plant cellulose microfibrils remains elusive, despite the abundance of cellulose and its utility in industry. Using 2D solid-state NMR of 13 C-labeled never-dried plants, six major glucose environments are resolved, which are common to the cellulose of softwood, hardwood, and grasses. These environments are maintained in isolated holocellulose nanofibrils, allowing more detailed microfibril characterization. We show that there are only two glucose environments that reside within the microfibril core. These have the same NMR 13

Rotational Projection Errors in Coronal Knee Alignment on Weight-Bearing Whole-Leg Radiographs: A 3D CT Reference Across CPAK Morphotypes

Igor Strahovnik, Andrej Strahovnik, Samo K. Fokter · 2025 · Bioengineering

Whole-leg radiographs (WLRs) are widely used to assess coronal alignment before total knee arthroplasty (TKA), but may be inaccurate in patients with atypical morphotypes or malrotation. This study evaluated the discrepancy between WLR and 3D computed tomography (CT) scans across coronal plane alignment of the knee (CPAK) morphotypes and introduced a novel projection index—the femoral notch projection ratio (FNPR). In CPAK III knees, 19% of cases exceeded a clinically relevant threshold (>3° difference), prompting investigation of underlying projection factors. In 187 knees, coronal angles—
