Spatial Matching of 2D Mammography Images and Specimen Radiographs: Towards Improved Characterization of Suspicious Microcalcifications [PDF]

Medical Imaging 2021: Computer-Aided Diagnosis (Vol. 11597, pp. 511-516). SPIE
Accurate characterization of suspicious microcalcifications is critical to determine whether these calcifications are associated with invasive disease. Our overarching objective is to enable the joint characterization of microcalcifications and surrounding breast tissue using mammography images and digital histopathology images.

Encapsulation of Small Extracellular Vesicles into Selectively Disassemblable Shells of PEGylated Metal‐Phenolic Networks

Advanced Healthcare Materials, EarlyView.
Small extracellular vesicles (sEVs) are encapsulated into protective shells composed of metal‐phenolic networks (MPNs) and secondary poly(ethylene glycol) layers. This surface modification approach enhances the storage stability of sEVs while maintaining their integrity and functionality. The shells can be selectively disassembled under mild conditions.

RICAU-Net: Residual-block Inspired Coordinate Attention U-Net for Segmentation of Small and Sparse Calcium Lesions in Cardiac CT [PDF]

arXiv
The Agatston score, which is the sum of the calcification in the four main coronary arteries, has been widely used in the diagnosis of coronary artery disease (CAD). However, many studies have emphasized the importance of the vessel-specific Agatston score, as calcification in a specific vessel is significantly correlated with the occurrence of ...

Silicon Nanowire Mats Enable Advanced Bioelectrical Recordings in Primary DRG Cell Cultures

Advanced Healthcare Materials, EarlyView.
SiNW mat‐based MEA (NW_MEA) enables continuous intracellular recordings from neurons in primary rat DRG cell cultures, identifying C‐fiber nociceptors. Supported by an astrocyte feeder layer, SiNW mat promotes DRG neuron and glial cell growth, preserving in vivo‐like cell characteristics and allowing drug‐modulated activity monitoring.

Vorticity‐Facilitated Platelet Aggregation: a High Expansion‐Ratio Stenotic Microfluidic Platform Unravels the Role of Complex Flow Dynamics in Arterial Thrombosis

Advanced Healthcare Materials, EarlyView.
This study reveals how vorticity—a swirling flow pattern—enhances platelet aggregation and thrombus formation in high‐shear conditions. Using a custom microfluidic model, it is shows that vorticity promotes vWF–GPIbα interactions and calcium signaling, providing new insights into thrombosis mechanobiology and informing safer blood‐contacting medical ...

Permeation Enhancer‐based Ionogel Shows Remarkable Potential for Oral Insulin Delivery

Advanced Healthcare Materials, EarlyView.
This study proposes a novel formulation of decanoate in an ionic liquid inspired drug delivery system. The formulation demonstrates ideal physicochemical and material properties for oral peptide delivery. Findings indicate that choline decanoate (1:2 molar ratio) forms a viscoelastic gel that enables high oral bioavailability of insulin in rats ...

Si Inhibited Osteoclastogenesis: The Role of Fe and the Fenton Reaction

Advanced Healthcare Materials, EarlyView.
Silicate (Si) inhibition of osteoclastogenesis, is mediated by Fe. Si chemical interactions with Fe inhibit the Fenton reaction and intercellular ROS availability. This reduction in ROS availability inhibits osteoclastogenesis. The addition of Fe, in Si‐inhibited osteoclast cultures, restores the Fenton reaction, and osteoclastogenesis.
