Longitudinal progression, metrics, age-dependence, and modifiers of ataxia severity in SCA27B: a multicentre study of 219 patients

Background Spinocerebellar Ataxia 27B (SCA27B) is a novel, frequent and likely treatable late-onset autosomal-dominant ataxia caused by GAA repeat-expansions in FGF14 . For understanding disease evolution and imminent trial planning, metrics of the most widely used clinical outco...

Effect of chronic high‐altitude hypoxia on retinal vascular phenotype, choroidal and retinal vasoreactivity in Peruvian highlanders

Abstract High‐altitude chronic hypoxia can induce excessive erythrocytosis (EE, defined as a haemoglobin concentration of ≥21 g/dL in men), leading to hyperviscosity and promoting endothelial dysfunction. We aimed to assess whether EE affects the retinal vascular phenotype and th...

Timing of antifibrotic therapy and prognosis in idiopathic pulmonary fibrosis: real-world evidence from the French Colibri-ILD SNDS database

According to the French 2022 National guideline, antifibrotic therapy should be initiated as soon as a diagnosis of idiopathic pulmonary fibrosis (IPF) is made, taking into account the individual assessment of the expected benefit and risks of treatment. However, in practice, tre...

A dendritic cell autophagy–neutrophil axis limits intratumoral STING immunotherapy

The cyclic GMP-AMP synthase (cGAS)–stimulator of interferon genes (STING) pathway promotes tumor immunogenicity, but intratumoral STING agonists, despite strong preclinical efficacy, have shown limited clinical efficacy. The mechanisms restricting therapeutic STING activation rem...

Critical neuronal avalanches arise from excitation-inhibition balanced spontaneous activity

Neuronal avalanches are sequences of neural activations exhibiting scale-invariant statistics, indicative of critical dynamics. Theoretical studies proposed that the balance between excitation (E) and inhibition (I), along with neuromodulation, are key factors influencing this cr...

Unraveling HBV Life Cycle by Fluorescent Microscopy Imaging

The hepatitis B virus (HBV) is a worldwide hepatotropic virus despite the availability of a highly effective vaccine. Currently, the most efficacious treatment against HBV infection is the use of interferon and nucleos(t)ide analogs, which effectively suppress viral replication b...

PLCG2 downregulation impairs synaptic function and increases Alzheimer’s disease hallmarks in neuronal cultures

We developed a high-content screening to investigate how Alzheimer’s disease (AD) genetic risk factors may affect synaptic mechanisms in rat primary neuronal cultures. Of the target genes identified, we found that Plcg2 downregulation in mouse dentate gyrus neurons consistently d...

Efficacy of rTMS in Post‐Stroke Bilingual Aphasia: A Single Case Experimental Design

BACKGROUND: The application of non-invasive brain stimulation in the rehabilitation of bilingual individuals with aphasia following a stroke is understudied. Recent studies show benefits of anodal cerebellar transcranial Direct Current Stimulation in bilinguals, while in monoling...

Questioning the Evidence for Host-Symbiont Codiversification in Mycorrhizal Symbioses

Abstract The vast majority of plants form mycorrhizal symbioses. The ecological importance of these mutualistic interactions has sparked interest in their long evolutionary history. By examining interaction networks and phylogenetic trees, several studies have suggested that plan...

The extreme diversity of retinal amacrine cells has deep evolutionary roots

Amacrine cells (ACs) comprise a heterogeneous class of inhibitory neurons in the vertebrate retina, exhibiting morphological and functional complexity rivaling that of cortical interneurons. Here, we integrate single-cell and single-nucleus transcriptomic atlases from 24 vertebra...

Robot-Assisted Versus Open and Laparoscopic Radical Nephrectomy with Inferior Vena Cava Thrombectomy forRenal Cell Carcinoma: A Systematic Review and Meta-Analysis

Background/Objectives: To compare perioperative, pathological, functional, and oncological outcomes of robot-assisted radical nephrectomy with inferior vena cava tumor thrombectomy (RARN-TT) versus open (ORN-TT) and laparoscopic (LRN-TT) approaches. Methods: PubMed, Scopus, and W...

Agreement of Hematologic Measurements Between Jugular and Coccygeal Puncture Sites in Cattle

ABSTRACT Background In bovine medicine, venipuncture is commonly performed at either the jugular or coccygeal vein. Although the coccygeal site is often preferred for practical reasons, sampling sites are inconsistently standardized in scientific studies. It is therefore importan...

Seed-based functional connectivity of the anterior cingulate cortex and the posterior insula predicts placebo analgesia in Parkinson’s disease

Chronic pain affects up to 80% of people with Parkinson’s disease (PD) and remains difficult to treat. Functional brain connectivity can predict analgesic response in other conditions, but has not been explored in PD. To assess whether baseline resting-state functional connectivi...

DOPAL links dopamine dysregulation to neurodegeneration: a translational systematic review and meta-analysis

3,4-Dihydroxyphenylacetaldehyde (DOPAL) is the most reactive dopamine (DA)-derived aldehyde and has been implicated in selective dopaminergic neurodegeneration in α-synucleinopathies, including Parkinson’s disease (PD) and multiple system atrophy (MSA). Here, we present the first...

Conserved dimerization architecture in C‐type lectins from virus‐vector mosquitoes

Abstract C-type lectins (CTLs) play key roles in innate immunity and microbial carbohydrate recognition. In the disease vector mosquito Aedes aegypti , the CTLD-S family comprises 34 soluble CTLs whose members are implicated in flavivirus dissemination and microbial homeostasis,...

Macrophage heterogeneity in human secondary lymphoid organs

Abstract Macrophages play a major role in immune responses and in the maintenance of tissue homeostasis. Most of our knowledge of macrophage biology comes from mouse studies, which have revealed the existence of distinct subpopulations differing in origin, life cycle and tissue-s...

Adrenaline Use and Request for Emergency Medical Assistance to Manage Food Anaphylaxis

Summary Adrenaline was rarely used, medical assistance being requested in two thirds of anaphylaxis cases. Medical assistance request was less frequent if milder or no cardiovascular anaphylaxis symptoms.

Adherence to Biologics and Psycho-cognitive Factors in Axial Spondyloarthritis: A Multicentric Cross-sectional Study

Background/Objective: Adherence to treatment in axial spondyloarthritis (axSpA) remains poorly documented, with estimates ranging from 28.2% to 70.6%. Psychological factors may influence adherence. This study aimed to assess adherence to biological disease-modifying antirheumatic...

Prospective analysis of pre-diagnostic untargeted plasma metabolomics and risk of triple-negative breast cancer in the European Prospective Investigation into Cancer and Nutrition (EPIC)

Triple-negative breast cancer (TNBC) accounts for 10–15% of newly diagnosed breast cancer, and its aetiology is poorly understood compared to other breast cancer subtypes. We applied untargeted metabolomics to identify novel biological pathways associated with TNBC risk and poten...

Association between Pulmonary Vascular Obstruction Phenotype and Pulmonary Embolism Recurrence: Results from the PADIS-PE Study

Pulmonary vascular obstruction index (PVOI), assessed using the Qanadli index on computed tomography pulmonary angiography (CTPA) at pulmonary embolism (PE) diagnostic, has been associated with recurrence after unprovoked PE, but its complexity limits routine use. We aimed to eva...
