The Pavlovian interpretation of speech and aphasia: Alexander Luria and Wilder Penfield

open access: yesFrontiers in Psychology
This paper discusses a neglected aspect of the historiography of aphasia, the role that Pavlovian conditioning played in Alexander Luria’s and Wilder Penfield’s understanding of the acquisition, expression, and loss of spoken and written speech.

Expression, Purification, and Microscopy‐Based Assays for Engineered Recombinant Tyrosinated, Detyrosinated, and Δ2 Human Tubulin

open access: yesCytoskeleton, EarlyView.
ABSTRACT Microtubules are noncovalent polymers assembled from α/β tubulin dimers. Their structure, dynamics and interaction with effectors are regulated through the expression of diverse tubulin isotypes and chemically diverse posttranslational modifications, also known as the “tubulin code.” Understanding the biophysical correlates between tubulin ...

Morphological signatures of bacteria‐laden drying droplets: A multimodal analysis across host fluids

open access: yesDroplet, EarlyView.
Drying patterns of bacteria‐laden droplets encode concentration‐dependent signatures across three host fluids: serum, urine, and nutrient medium. By integrating time‐evolving texture descriptors, image features, and interpretable multimodal machine learning, this study demonstrates a label‐free approach for extracting information on bacterial ...

Phase‐Change‐Activated Slippery Organogel Composite for All‐in‐One Anti‐Corrosion, Antifouling, and Self‐Cleaning

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A super‐slippery liquid‐infused composite organogel is engineered by localized interfacial grafting between hydrogel and oleogel networks, endowing the coating with a durable, multifunctional marine‐protective interface. Dynamic antifouling surfaces have emerged as a promising alternative, offering the potential for eco‐friendly and high‐performance ...

Light‐Driven Butyrate Production by a Probiotic Clostridium tyrobutyricum Enabled by a Cell‐Semiconductor Hybrid Interface

open access: yesFood Chemistry International, EarlyView.
This schematic illustrates a light‐driven biohybrid system where CdS nanoparticles, mineralized on the probiotic Clostridium tyrobutyricum, inject photoelectrons to elevate intracellular NADH. This boosts the flux through key NADH‐dependent enzymes (GapA, Hbd, and Bcd), reprogramming metabolism to enhance butyrate yield by 33.2% and selectivity to 95.7%

Extraction of Antimicrobial Peptides From Fava Bean Protein Hydrolyzate by Phosphorylated Biochar

open access: yesFood Safety and Health, EarlyView.
Antimicrobial peptides were extracted by functional biochar in one step. The enriched peptides demonstrated significantly enhanced antibacterial activity. ABSTRACT The extraction of antimicrobial peptides (AMPs) from plant proteins remains challenging due to their low abundance, structural diversity, and the need for mild, efficient, and selective ...

Os estágios que constituem a história da pré-escrita: reflexões a partir dos experimentos realizados com crianças não alfabetizadas

open access: yesHorizontes, 2013
Neste artigo apresentamos alguns dados da educação no solo da Revolução Russa de 1917 que contribuíram para o surgimento da teoria histórico-cultural, liderada por Vigostski e desenvolvida por um grupo de pesquisadores russos.

Bacterial indole‐3‐butyric acid promotes fish PUFA synthesis

open access: yesiMetaOmics, EarlyView.
Polyunsaturated fatty acids (PUFAs) are essential nutrients in aquatic products, yet the contribution of gut microbiota‐derived metabolites to PUFA biosynthesis remains largely unknown. In this study, a gut‐derived Bacillus strain was identified to enhance PUFA accumulation via indole‐3‐butyric acid (IBA) production.
