Differential Scanning Calorimetric (DSC) Study of New and Sterilized Nickel-Titanium Rotary Endodontic Instruments [PDF]

, 2015
Introduction: Nickel-Titanium (NiTi) files have become popular in endodontic procedures compared to traditional stainless steel hand files owing to their increased flexibility which is especially advantageous in curved canals. Due to the associated costs,

Organoid Modeling of Mouse Anterior Tongue Epithelium Reveals Regional and Cellular Identities

Advanced Science, EarlyView.
The tongue's anterior epithelium is maintained by region‐specific stem/progenitor cells, yet in vitro models are limited. Long‐term expanding organoids are developed from adult mouse anterior tongue that retain region‐specific identity, cellular diversity, and gene regulatory features. These organoids differentiate into keratinocytes, Merkel‐like cells,

Tailoring Vascular‐Immune Homeostasis via Manganese‐DNA Complex‐Armed Immunogenic Extracellular Vesicles for Pancreatic Cancer Immunotherapy

Advanced Science, EarlyView.
This study demonstrates that Mn2⁺–tumor DNA complexes encapsulated in dendritic cell (DC)– derived immunogenic extracellular vesicles (EVDC@Mn‐DNA) act as a DC‐specific cGAS– STING activator. EVDC@Mn‐DNA treatment enhances intratumoral DC activation, improves tumor vascular function, promotes CD8⁺ T cell activity, and suppresses pancreatic tumor growth,

Targeted Expansion of Treg Cells to Induce Immune Tolerance after Kidney Transplantation

Advanced Science, EarlyView.
A dual‐targeting nanoparticle platform that selectively engages graft stromal cells via CD248 receptors while employing kidney‐ specific promoters (NPHS2) to drive localized IL‐ 2/TGF‐βexpression is developed. This approach achieves three therapeutic objectives:1) intragraft Treg polarization without systemic cytokine exposure;2) reduced dependence on ...

Auditory Hair Cell Mechanotransduction Channels Dynamically Shape the Mechanical Properties of Their Membrane Environment

Advanced Science, EarlyView.
This work shows, for the first time, that the stereocilia membrane in cochlear hair cells is dynamically regulated by the mechanotransduction channel to impact the membrane mechanical properties. This work provides direct evidence that the opening and closing associated with the MET channel is regulating the membrane viscosity suggesting that the MET ...

Synergistic Promotion of Triple‐Negative Breast Cancer Tumorigenesis and Metastasis by Oral Polystyrene Nanoplastics Exposure via Alloprevotella‐Derived Glutamate and Platelet Activation

Advanced Science, EarlyView.
Polystyrene nanoplastics (PS‐NPs) administered via oral exposure accelerate triple‐negative breast cancer (TNBC) progression by synergistically modulating gut microbiota‐derived glutamate production and platelet activation. This study uncovers a pivotal crosstalk between microbial metabolites and platelet‐tumor interactions, offering mechanistic ...
