Flash Assembloids: A Rapid Biofabrication of a Platform for Modeling Early Glioblastoma Invasion at the Glioblastoma–Brain Organoid Interfaces

open access: yesAdvanced Healthcare Materials, EarlyView.
This study presents a bioengineered assembloid (ASM) system combining glioblastoma (GBM) cells in oxidized alginate (OA) microgels with dorsal organoids (DOs). This model simulates brain tumor‐host interactions, revealing enhanced GBM invasion, altered gene expression, and aggressive infiltration patterns, demonstrating ASM as a valuable platform for ...

Mimetic Core‐Sheath Silk Sutures with Superior‐Strength for Pain Management, Anti‐Infection and Wound Healing

open access: yesAdvanced Healthcare Materials, EarlyView.
ABSTRACT Sutures are crucial for tissue approximation and wound healing. Besides their strength limits requirement, they often fail to effectively address complications like infection and pain. Inspired by natural silk's “core‐sheath” structure, our suture features a wet‐spun core of n zinc‐fortified silk fibroin fibers (RSF‐Zn2+) after drawing with ...

HOF‐Stabilized Apple EV Nanocargo in an NIR‐Responsive Hydrogel Enables On‐Demand Therapeutic Modulation for Transdermal Deep‐Joint Osteoarthritis Therapy

open access: yesAdvanced Healthcare Materials, EarlyView.
An NIR‐responsive transdermal hydrogel integrating apple EV nanocargo, berberine, piperine, HOFs, and graphene oxide enables localized osteoarthritis modulation. The platform supports enhanced transdermal delivery together with mild hyperthermia‐associated and redox‐related responses, leading to reduced inflammation and oxidative stress, improved ...

3D Bioprinted Breast Cancer‐Stroma Model with Tailored Migration‐Permissive Bioink Reveals Impact of Adipose‐Derived Stromal Cells on Cancer Cell Migration and Invasion Dynamics

open access: yesAdvanced Healthcare Materials, EarlyView.
A migration‐permissive bioink composed of methacrylated collagen type I and thiolated hyaluronic acid enables 3D bioprinting of breast cancer‐stroma models. Single‐cell tracking reveals that adipose stromal cells enhance tumor cell motility and stromal invasion, accompanied by collagen remodeling, and a shift in tumor cell morphology.

Channel Estimation for OFDM-Based Amplify-and-Forward Cooperative System Using Relay-Superimposed Pilots

open access: yesInternational Journal of Digital Multimedia Broadcasting, 2018
For the OFDM-based Amplify-and-Forward cooperative system, a novel relay-superimposed pilot strategy is proposed, where the source pilot symbols are frequency division multiplexed to estimate the cascaded channel while relay pilot sequence is ...

Cellular Responses to Mechanical Cues Across Scales: From Fundamental Insights to Translational Potential

open access: yesAdvanced Healthcare Materials, EarlyView.
This review examines how cellular behavior is regulated by mechanical cues transmitted through soft biomaterials, from single‐cell mechanosensing to tissue‐level adaptation. It highlights why physiological relevance, rather than model complexity alone, is critical for translational mechanobiology and introduces a scoring framework linking material ...

Gardiquimod Nanoemulsion Targets Cutaneous Leishmaniasis Lesions Reducing Systemic Toxicity and Parasite Burden

open access: yesAdvanced Healthcare Materials, EarlyView.
Nanoemulsion delivery of a TLR7 agonist enhances safety and promotes colocalization with Leishmania‐infected macrophages in skin lesions, enabling a ∼2‐log reduction in parasite burden. However, tissue‐level constraints and TLR‐driven regulatory feedback generate a mixed immune response that limits complete parasite clearance.

Rational Design of Organic Chromophores for Simultaneously Trig‐gering Redox Imbalance and Tracking Organelles in Biological Sys‐tems Under Near‐Infrared Light Irradiation

open access: yesAdvanced Healthcare Materials, EarlyView.
TOC represents the synthesis of theory‐guided novel near‐infrared (NIR) light‐absorbing organic photosensitizers (OPS) enabling redox‐induced tumor phototherapy and single‐cell organelle tracking. ABSTRACT The design of organic photosensitizers that operate efficiently in the near‐infrared (NIR) region remains challenging due to the need to balance ...

Multi-Filter Quantum Neural Networks for Efficient Channel Estimation in RIS-Assisted Systems

open access: yesSensors
A reconfigurable intelligent surface (RIS) is a promising technology for beyond-fifth-generation (B5G) and sixth-generation (6G) wireless communications, but its passive reflection and two-hop double-fading structure make cascaded channel estimation ...
