Structural Polymorphism of polyG Inclusions Revealed by In Situ Cryo‐Electron Tomography

Advanced Science, EarlyView.
Correlative cryo‐electron tomography in primary cortical neurons and NIID mouse brain tissue reveals that polyG inclusions are interconnected ribbon‐like assemblies rather than canonical amyloid fibrils. Multiple compartment‐specific ribbon states show distinct 26S proteasome accessibility, while cytoplasmic ribbons contact and deform ER‐like ...

Gap‐Free Information Transfer in 4D‐STEM via Fusion of Complementary Scattering Channels

Advanced Science, EarlyView.
Fused Full‐Field STEM (FF‐STEM) is introduced as a 4D‐STEM imaging modality that combines direct ptychography with tilt‐corrected dark‐field reconstruction in a single acquisition. Fourier‐space fusion using Wiener‐type spectral weighting closes the low‐frequency contrast gap inherent to bright‐field methods, delivering gap‐free, dose‐efficient, near ...

A Large Open Pangenome and a Small Core Genome for Giant Pandoraviruses

Frontiers in Microbiology, 2018
Giant viruses of amoebae are distinct from classical viruses by the giant size of their virions and genomes. Pandoraviruses are the record holders in size of genomes and number of predicted genes. Three strains, P. salinus, P. dulcis, and P.

Morphological and Genomic Features of the New Klosneuvirinae Isolate Fadolivirus IHUMI-VV54

Frontiers in Microbiology, 2021
Since the discovery of Mimivirus, viruses with large genomes encoding components of the translation machinery and other cellular processes have been described as belonging to the nucleocytoplasmic large DNA viruses. Recently, genome-resolved metagenomics

Single‐Atom‐Enhanced Fully Inkjet‐Printed Electrochemical Sensor for Dopamine Detection

Advanced Science, EarlyView.
Fully inkjet‐printed paper‐based dopamine sensors are fabricated using nitrogen‐doped graphene acid functionalized with copper single atoms. The copper sites uniquely enhance dopamine oxidation through strong molecular adsorption, as verified by electrochemical measurements and DFT calculations. The approach highlights the potential of single‐atom inks

Mimivirus transcription and translation occur at well-defined locations within amoeba host cells

Journal of Virology
Many giant viruses replicate in the cytoplasm in viral factories. How exactly these viral factories are established and where the different steps of the replication cycle occur remain largely obscure.

Canonical Antibodies Adopt Distinct Binding Modes to Recognize Viral Glycan Shields

Advanced Science, EarlyView.
Canonical Y‐shaped antibodies recognize viral glycan shields through adaptive Fab assembly states shaped by glycan organization and somatic hypermutation. Structural analyses ofbroadly neutralizing antibodies VRC35 and VRC36 across glycoproteins of HIV‐1, influenza, SARS‐CoV‐2, and Lassa viruses reveal distinct Fab assembly states, spanning monovalent,

Genotype–Phenotype Correlations of Monoallelic PFIC Variants in Pediatric Liver Disease: A Multicenter Retrospective Cohort Study

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Progressive familial intrahepatic cholestasis (PFIC) is classically caused by biallelic pathogenic variants, yet monoallelic variants of uncertain significance (VUS) in PFIC‐associated genes are increasingly identified in children with cholestasis, creating diagnostic uncertainty.
