Antioxidant and Anti‐Senescence Polyvinyl Alcohol‐Gallic Acid Supramolecular Hydrogels for Stem Cell Culture

Advanced Healthcare Materials, EarlyView.
The PVA‐GA hydrogel is formed through hydrogen bonding between PVA hydroxyl groups and GA galloyl units, enabling sustainable GA release and its extended biological activity. The hydrogel scavenges ROS to reduce oxidative stress, preventing mitochondrial damage from excessive ROS, mitigating hADSC senescence, and preserving VEGF secretion, offering a ...

Alterations in Maternal–Fetal Heart Rate Coupling Strength and Directions in Abnormal Fetuses

Frontiers in Physiology, 2019
Because fetal gas exchange takes place via the maternal placenta, there has been growing interests in investigating the patterns and directions of maternal-fetal cardiac coupling to better understand the mechanisms of placental gas transfer.

Evaluation and patient experience of wireless noninvasive fetal heart rate monitoring devices [PDF]

Introduction: In clinical practice, fetal heart rate monitoring is performed intermittently using Doppler ultrasound, typically for 30 minutes. In case of a non-reassuring heart rate pattern, monitoring is usually prolonged.

Controlled Release of Human Dental Pulp Stem Cell‐Derived Exosomes from Hydrogels Attenuates Temporomandibular Joint Osteoarthritis

Advanced Healthcare Materials, EarlyView.
Exosomes can reduce tissue damage in temporomandibular joint osteoarthritis (TMJOA), but rapid clearance limits their efficacy. This study encapsulates exosomes in hyaluronic acid hydrogels for controlled release. In a rat model, hydrogel‐encapsulated exosomes outperform free exosomes in preserving bone integrity and reducing tissue destruction ...

3D Bioprinted Head and Neck Squamous Cell Carcinoma (HNSCC) Model Using Tunicate Derived Nanocellulose (NC) Bioink

Advanced Healthcare Materials, Volume 14, Issue 7, March 14, 2025.
A 3D bioprinted HNSCC model for use in anti‐cancer drug testing is established in proof‐of‐concept. The innovative tunicate‐derived nanocellulose hydrogel proved to be a viable alternative to gelatin‐based hydrogel, offering improved bioprintability for HNSCC model establishment.

Soft Pneumatic Device Designed to Mimic the Periosteal Environment for Regulating the Fate of Mesenchymal Stem Cells

Advanced Healthcare Materials, EarlyView.
This study presents a custom‐made soft pneumatic device (SPD) that mimics complex mechanical forces and fluid flow to enhance in vitro cell differentiation. It shows that low mechanotransduction promotes MSC differentiation into osteoprogenitor cells, while high mechanotransduction causes structural disruptions and cell detachment, providing new ...

Salt‐Compact Albumin as a New Pure Protein‐based Biomaterials: From Design to In Vivo Studies

Advanced Healthcare Materials, Volume 14, Issue 7, March 14, 2025.
A new class of materials built entirely of native albumin protein is designed using a simple protocol based on salt‐assisted compaction, breaking with current crosslinking strategies. This green process leads, surprisingly, to water‐insoluble handable materials with high preservation of their native protein structures and Young's modulus close to that ...

Bioengineering a Patient‐Derived Vascularized Lung Tumor‐on‐Chip Model to Decipher Immunomodulation by the Endothelium

Advanced Healthcare Materials, EarlyView.
Most in vitro cancer models lack cellular diversity, functional complexity, and clinical relevance. This work highlights the generation of an innovative dynamic tetraculture with autologous patient‐derived cells within a vascularized tumor‐on‐chip, as well as the recapitulation of endothelial anergy features induced by the tumor microenvironment ...

Fetal Heart Rate Preprocessing Techniques: A Scoping Review

Bioengineering
Monitoring fetal heart rate (FHR) through cardiotocography is crucial for the early diagnosis of fetal distress situations, necessitating prompt obstetrical intervention. However, FHR signals are often marred by various contaminants, making preprocessing
