Graded Hydroxyapatite Triply Periodic Minimal Surface Structures for Bone Tissue Engineering Applications

Advanced Healthcare Materials, EarlyView.
This study investigates the role of triply periodic minimal structures in load bearing bone tissue engineering applications. Research uses a combination of mechanical testing, material characterization, and in vitro tests to study the impact of TPMS lattice structures (gyroid, lidinoid and split‐P).

An Intervertebral Disc (IVD) Regeneration Model Using Human Nucleus Pulposus Cells (iHNPCs) and Annulus Fibrosus Cells (iHAFCs)

Advanced Healthcare Materials, EarlyView.
This study investigates hTert‐immortalized human nucleus pulposus (iHNPCs) and annulus fibrosus (iHAFCs) cells for intervertebral disc (IVD) regeneration and spinal fusion models. A 3D‐printed citrate‐based scaffold loaded with BMP9‐stimulated iHAFCs and BMP2‐stimulated iHNPCs effectively promotes bone and cartilage formation, mimicking the IVD ...

Identification of mineralization in geochemistry along a transect based on the spatial curvature of log-ratios [PDF]

arXiv, 2019
Detecting subcropping mineralizations but also deeply buried mineralizations is one important goal in geochemical exploration. The identification of useful indicators for mineralization is a difficult task as mineralization might be influenced by many factors, such as location, investigated media, depth, etc.

Multiscale Thermal Analysis of Gold Nanostars in 3D Tumor Spheroids: Integrating Cellular‐Level Photothermal Effects and Nanothermometry via X‐Ray Spectroscopy

Advanced Healthcare Materials, EarlyView.
This study investigates nanoscale temperatures generated by photoexcited gold nanostars and their correlation with microscale thermal damage at the cellular level. Using X‐ray absorption spectroscopy and confocal microscopy in 3D cancer spheroids, it assesses localized heating effects and examines tumor cell structure and integrity, offering insights ...

Longer Acting Injectable: Continuous, Linear Release of a Progestin Contraceptive From an Oxidized Porous Silicon Host

Advanced Healthcare Materials, EarlyView.
Progestin drugs are loaded into a mesoporous silicon dioxide host by melt‐infiltration. Drugs that decompose at or close to their melting point can be loaded by the addition of cholesterol, which acts as a melting point suppressor. High mass loading of the drug is achieved, and dissolution of the composite is controlled by the nanoscale properties of ...

Universal Hydrogel Carrier Enhances Bone Graft Success: Preclinical and Clinical Evaluation

Advanced Healthcare Materials, EarlyView.
TX hydrogel improves the delivery of different types of particulate bone grafts, maintaining them at the implantation sites, and resulting in favorable bone regenerative outcomes. Abstract Orthopedic, maxillofacial, and complex dentoalveolar bone grafting procedures that require donor‐site bone harvesting can be associated with post‐surgical ...

Characterisation of the mechanical and thermal degradation behaviour of natural fibres for lightweight automotive applications [PDF]

, 2013
It is well established that light-weighting of automotive parts leads to reduced carbon emissions over vehicle lifetime. Mineral fibres and fillers have a relatively high density and may require high levels of energy in their production, resulting in a ...

Novel Protein‐Rich Bioactive Bioink Stimulates Cellular Proliferation and Response in 3D Bioprinted Volumetric Constructs

Advanced Healthcare Materials, EarlyView.
This work describes a protein‐rich, low‐cost, bioactive bioink, prepared by adding eggwhite powder to functionalize an established alginate‐methylcellulose hydrogel blend and enhance its cellular response. The bioink not only maintains favorable printability and high shape fidelity but also exhibits remarkable bioactivity, thereby improving the ...
