Visualization of Endosomal Escape of Intracellularly Delivered Protein With Unexpected Photochemical Internalization of Trypan Blue

open access: yesAdvanced Science, EarlyView.
TB, a conventional cell viability dye, acts as both a fluorescence modulator (quenching GFP fluorescence upon protein binding and recovering it upon release) and a photosensitizer that triggers endosomal escape via photochemical internalization (PCI) under 590 nm light.

A Soft Robotic Model for Simulating Heart Valve Disease and Cardiac Interventions

open access: yesAdvanced Science, EarlyView.
This paper introduces a fully synthetic fabrication methodology for a soft robotic, in‐vitro model of the left‐heart, complete with a functioning mitral valve apparatus. With a view towards patient‐specific modeling, we demonstrate physiological flow and pressure waveforms, tunable mitral valve function with clinical imaging compatibility, and its use ...

Cryo‐EM Structure Guided Engineering of Botulinum Neurotoxin A With Advanced Receptor Binding Affinity and Therapeutical Benefits

open access: yesAdvanced Science, EarlyView.
The butterfly unfolded wing in an open form structure of botulinum neurotoxin type A (BoNT/A) at physiological‐state was confirmed at 2.85 Å resolution by cryo‐electron microscopy (cryo‐EM). Structure‐guided protein engineering significantly enhanced the receptor‐binding affinity, therapeutic efficacy, and safety of the engineered toxin variants ...

PET Imaging of Cardiac Inflammation in Viral Myocarditis Using a DPP4‐Targeted Probe

open access: yesAdvanced Science, EarlyView.
This study describes a DPP4‐targeted PET probe for imaging myocardial inflammation by selectively targeting activated immune cells. Derived from the clinically approved small‐molecule inhibitor linagliptin, the probe demonstrates favorable biodistribution with specific cardiac uptake in myocarditis.

In vitro Antibacterial Action of Extracts from Coptis Root

open access: yesExperimental Biology and Medicine, 1948
SummaryThe dilute alcohol extract of the coptis root has been demonstrated to have a definite and fairly high antibacterial action against a number of both Gram positive and Gram negative bacteria. Its lethal dose for albino rats has been found to be more than 250 mg per kg body weight.The author wishes to express his deep gratitude to Professor Samuel

Self‐Assembling Hybrid Hydrogel Reprograms the Stromal Vascular Fraction to Treat Osteoarthritis

open access: yesAdvanced Science, EarlyView.
This study presents a bioinspired injectable hydrogel that enhances the therapeutic potential of stem cell‐rich stromal vascular fraction for treating osteoarthritis. By reprogramming cell behavior through epigenetic modulation, the hydrogel promotes cartilage regeneration and reduces joint damage in a rat model, offering a promising new approach for ...

SKOOTS: Skeleton‐Oriented Object Segmentation for Mitochondria in High‐Resolution Cochlear EM Datasets

open access: yesAdvanced Science, EarlyView.
Skeleton‐oriented object segmentation (SKOOTS) introduces a new strategy for 3D mitochondrial instance segmentation by predicting explicit skeletons rather than relying on boundary cues. This approach enables robust analysis of densely packed organelles in large FIB‐SEM datasets.

Effect of Auxins and Activated Carbon on In Vitro Rooting of Two Blueberry Cultivars (Vaccinium corymbosum)

open access: yesJournal of Horticultural Research
The optimization of tissue culture protocols for blueberry propagation is crucial to meet the increasing demand for disease-free planting materials. This study aimed to determine the effects of three auxins (IBA, IAA, and NAA) at different concentrations

Multi‐Enzyme Mimetic Molybdenum Nitride Nanozymes Reshape Subgingival Microenvironment for Synergistic Periodontitis Therapy via ROS Regulation and Microbiome Remodeling

open access: yesAdvanced Science, EarlyView.
ABSTRACT Periodontitis, a chronic inflammatory disease initiated and sustained by plaque microorganisms and host immune response, remains an intractable oral disease and a leading cause of tooth loss worldwide. Traditional mechanical debridement and adjunctive antibiotic or antiseptic therapy often shows limited efficacy due to the complex anatomical ...
