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

open access: yesAdvanced 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 ...

Quantum theory without Hilbert spaces

open access: yes, 2001
Quantum theory does not only predict probabilities, but also relative phases for any experiment, that involves measurements of an ensemble of systems at different moments of time.

Glucocorticoids Alter Bone Microvascular Barrier via MAPK/Connexin43 Mechanisms

open access: yesAdvanced Healthcare Materials, Volume 14, Issue 7, March 14, 2025.
Osteoporosis induced by Glucocorticoids (GCs) is a common complication of long‐term GC use in patients with inflammatory and autoimmune conditions, often leading to an increased fracture risk. A 3D bicellular endo‐osteo microfluidic platform is developed to explore pathogenic mechanisms underlying GCs‐induced osteoporosis, highlighting a novel MAPK ...

Thermoresponsive BrushGel Microcarriers for Efficient Cell Expansion and Enzyme‐Reduced Harvesting

open access: yesAdvanced Healthcare Materials, EarlyView.
Askari et al, report on temperature‐responsive microcarriers to minimize enzyme use and cost in dynamic cultures. Abstract Scaling up cell therapy requires efficient expansion of high‐quality cells. Microcarrier(MC)‐based systems offer high surface‐to‐volume ratios and reduce culture media usage.

Covalent Binding of Dexamethasone to Polyimide Improves Biocompatibility of Neural Implantable Devices

open access: yesAdvanced Healthcare Materials, EarlyView.
The covalent binding of dexamethasone to the surface of polyimide represents the electrically inert part of implantable intraneural devices. This ensures a sustained release of the drug for 9 weeks. In vitro and in vivo tests confirm the reduction of the foreign body reactions and the improved biocompatibility of dexamethasone functionalized polyimide.

Decoding Hydrogel Porosity: Advancing the Structural Analysis of Hydrogels for Biomedical Applications

open access: yesAdvanced Healthcare Materials, EarlyView.
Porosity governs transport mechanics in hydrogels, yet characterization in its native state remains challenging. This work harnesses particle tracking to uncover three‐dimensional pore geometric features in polyethylene glycol hydrogels. Measurements in the native state reveal pores characteristics are comparable to those obtained by cryogenic scanning

Imiquimod‐Loaded Phospholipid‐Free Small Unilamellar Vesicles Activate the Tumor Immune Microenvironment to Treat Liver Cancer and Liver Metastases

open access: yesAdvanced Healthcare Materials, EarlyView.
Imiquimod‐loaded nanoparticles (PFSUV‐IMQ) are found to decrease liver metastasis and liver tumor burden when administered intravenously. Flow cytometry, RNA‐seq and various experiments show that the anti‐tumor response is immune‐mediated by activating dendritic cells resulting in increased CD8 T cell infiltration and activity.

Suppressing t(4;11) Acute Leukemia by Lipopolymer Nanoparticle Delivery of siRNA Targeting KMT2A::AFF1 with Enhanced Extrahepatic Delivery

open access: yesAdvanced Healthcare Materials, EarlyView.
This study introduces a new lipopolymer nanoparticle (LPNP) system that efficiently delivers siRNA to leukemia cells. The LPNPs silence the leukemia fusion gene KMT2A::AFF1, induce apoptosis, and decrease leukemia burden in mice. These results demonstrate the potential of LPNPs as a targeted siRNA therapy for acute lymphoblastic leukemia.
