Determination of Gene‐Level Fitness Contributions Across the Mucin‐Utilization Network of Bacteroides thetaiotaomicron

Advanced Science, EarlyView.
Genome‐wide CRISPRi and RNA‐seq resolve how B. thetaiotaomicron converts host mucosal glycans into fitness. The study reveals a layered mucin‐utilization architecture in which capsular polysaccharides constrain surface access, extracellular CAZymes and peptidases show functional redundancy, and intracellular catabolic pathways create discrete metabolic

Electronic‐State Programming of Ultrasmall CeO2 Switches H2O2 Activation From Radical to Bio‐Inspired Nonradical 1O2 Generation for Combating Antibiotic Resistance

Advanced Science, EarlyView.
A scalable synthesis of carbon‐supported ultrasmall CeO2 nanoparticles with precisely tunable Ce electron density is reported. Electron‐lean Ce sites activate H2O2 exclusively via a nonradical pathway, enabling efficient HOBr and 1O2 production analogous to bromoperoxidase for contaminant and antibiotic resistance removal.

The methodological perspective in Vygotsky: the dialectical materialism
A perspectiva metodológica em Vygotsky: o materialismo dialético

Semina: Ciências Sociais e Humanas, 1994
Some concepts developed by the Soviet Psychology (especially by Vygotsky; Leonliev and Luria) are discussed. Based on the concepts, the historical and dialectic materialism for the children psychological development study are revived.

scH16S‐Seq Maps Klebsiella pneumoniae‐Associated Myeloid States and Reveals a CD38–NAD Immunometabolic Axis That Impairs Lysosomal Acidification in Sepsis

Advanced Science, EarlyView.
Single‐cell host–bacterial 16S co‐sequencing (scH16S‐seq) integrates cell‐associated bacterial 16S‐derived signals with host transcriptomes to resolve bacterial signal‐enriched myeloid states in Klebsiella pneumoniae sepsis. Complementary pharmacological and genetic analyses define a CD38–NAD immunometabolic axis connecting mitochondrial bioenergetic ...

Historical Highlight: The Luria-Delbrück Fluctuation Test – A Study of the Nature of Bacterial Mutations Conferring Resistance to Infection by Bacteriophage

Pathogens and Immunity
In 1943, Salvador Luria, then at Indiana University, and Max Delbrück, then at Vanderbilt, published an analysis of mutations in Escherichia coli conferring resistance to infection by bacterial viruses, also referred to as bacteriophages [1].

Mn/Zn Bimetallic MOF‐Integrated Hydrogel Alleviates Excessive Mitochondrial Fission in BMSCs to Promote Osteoporotic Jawbone Repair

Advanced Science, EarlyView.
Excessive reactive oxygen species (ROS) and chronic inflammation impair bone marrow‐derived mesenchymal stem cells (BMSCs), contributing to poor healing in osteoporotic jawbone defect. The gelatin methacryloyl hydrogel loaded with manganese‐doped zeolitic imidazolate framework (Mn‐ZIF‐8@GelMA) promotes regeneration through redox regulation and ...

The EXPLAIN Study: Exploring Arthrogryposis Multiplex Congenita in Adults in Norway — A Description of Demographic, Medical, and Neurological Findings

American Journal of Medical Genetics Part C: Seminars in Medical Genetics, EarlyView.
ABSTRACT Arthrogryposis Multiplex Congenita (AMC) encompasses several hundred conditions with diverse genetic, pathophysiological, and clinical origins. The overarching EXPLAIN study explores underlying causes and implications of AMC and represents the largest clinical cohort of adults with AMC reported to date.

Synthetic Particulate Subunit Vaccines Co‐Delivering Multiple Antigens Induce Protective Immunity Against Melioidosis

Advanced NanoBiomed Research, EarlyView.
Engineered endotoxin‐free Escherichia coli were used to assemble poly(3‐hydroxybutyrate) (PHB) biopolymer particles displaying multiple conserved Burkholderia pseudomallei antigens via PhaC‐mediated surface presentation. Following formulation with poly(I:C), the particulate vaccines induced antigen‐specific humoral and cellular immune responses ...

Hyper memory, synaesthesia, savants Luria and Borges revisited

Dementia & Neuropsychologia
In this paper, we investigated two subjects with superior memory, or hyper memory: Solomon Shereshevsky, who was followed clinically for years by A. R. Luria, and Funes the Memorious, a fictional character created by J. L. Borges.

Comparative Performance of Poly(Vinyl Alcohol)/Chitosan Hydrogels Reinforced With Kraft Lignin and Kraft Lignin Nanoparticles

Journal of Applied Polymer Science, EarlyView.
The use of kraft lignin and kraft lignin nanoparticles in poly(vinyl alcohol)/chitosan hydrogels was comprehensively compared. The results showed that a higher loading of lignin nanoparticles than bulk kraft lignin could be incorporated while maintaining favorable hydrogel properties, leading to improved overall performance. ABSTRACT The development of
