Real‐Time 3D Ultrasound Imaging with an Ultra‐Sparse, Low Power Architecture

Advanced Healthcare Materials, EarlyView.
This article presents a novel, ultra‐sparse ultrasound architecture that paves the way for wearable real‐time 3D imaging. By integrating a unique convolutional array with chirped data acquisition, the system achieves high‐resolution volumetric scans at a fraction of the power and hardware complexity.

Cardiac tissue engineering

, 2004
The restoration of normal cardiac function can potentially be achieved by functional tissue constructs grown in vitro by using differentiated or progenitor cells, biomaterial scaffolds and bioreactors. Engineered tissues can also serve as high-fidelity models for basic studies of cells and tissues, in response to gene alterations, drugs, hypoxia, or ...

Tunable Bioresorbable Scaffolds With Marine Sulfated Polysaccharides for Small‐Caliber Vascular Grafts: A Multi‐Layered Strategy Combining Electrospinning and 4‐Axis Printing

Advanced Healthcare Materials, EarlyView.
A multilayered small‐caliber vascular scaffold combining electrospinning and 4‐axis printing is developed and biofunctionalized with marine sulfated polysaccharides from Holothuria tubulosa. The resulting construct exhibits enhanced hemocompatibility, tunable mechanical properties, and supports endothelial and smooth muscle cell adhesion and ...

A Tri‐Culture Heart‐on‐a‐Chip Platform With iPSC‐Derived Cardiac Cells for Predictive Cardiotoxicity Testing

Advanced Healthcare Materials, EarlyView.
This study presents the first entirely isogenic heart‐on‐chip, unifying cardiomyocytes, fibroblasts, and endothelial cells from a single iPSC source. The platform reveals a critical biological insight: the endothelium actively shields cardiac tissue from drug‐induced toxicity, challenging the predictive accuracy of conventional, avascular models for ...

Nanotherapies for Atherosclerosis: Targeting, Catalysis, and Energy Transduction

Advanced Healthcare Materials, EarlyView.
Atherosclerosis management is hindered by poor drug targeting and plaque heterogeneity. Nanotechnology overcomes these barriers via three core strategies: (1) target‐engineered nanocarriers that achieve lesion‐specific precision via ligand modification, biomimetic camouflage, stimuli‐responsive release, and self‐propelling nanomotors; (2) catalytic ...

Ultrasound‐Triggered Nanobubbles for Endothelial‐Targeted Drug Delivery in the Detection and Treatment of Doxorubicin‐Induced Cardiotoxicity

Advanced Healthcare Materials, EarlyView.
The DA/VTP‐NBs selectively recognized cardiac ECs damaged by DIC and achieved cell‐level targeted imaging. Then US‐triggered controlled release successfully enabled the release of DAPA within the DA/VTP‐NBs at the site of injury. This precise on‐demand drug release approach amplifies a series of localized therapeutic effects through the mtDNA‐mediated ...

Opinion: Gavage Administration of MXene as a Route‐Specific Alternative to Intravenous Injection into the Bloodstream of Laboratory Animals for Reducing Systemic Nanotoxicity Risks in Immunosuppression and Post‐Transplantation Models with Bile Acid Modification

Advanced Healthcare Materials, EarlyView.
Recent studies reported immunosuppressive properties of specific MXene nanomaterials. Their intravenous injection into the bloodstream of laboratory animals has been a common delivery method to suppress systemic inflammation and prevent transplant rejection.

Immunity to MHC class I antigen after direct DNA transfer into skeletal muscle. [PDF]

, 1994
Plasmid cDNA encoding the alpha-chain of either membrane-bound (pcRT.45) or secreted (pcRQ.B3) RT1Aa MHC class I Ag were transferred to Lewis (RT1(1)) rat skeletal muscle by direct injection.

Rapid Fabrication of Self‐Propelled and Steerable Magnetic Microcatheters for Precision Medicine

Advanced Materials, EarlyView.
A rapid Joule heating fabrication method for the production of self‐propelling, adaptive microcatheters, with tunable stiffness and integrated microfluidic channels is presented. Demonstrated through three microrobotic designs, including a steerable guiding catheter, an untethered wave‐crawling TubeBot, and a distal‐end propelled microcatheter, it was ...
