Reservoir‐Type Subcutaneous Implantable Devices Containing Porous Rate Controlling Membranes for Sustained Delivery of Risperidone

open access: yesAdvanced Healthcare Materials, EarlyView.
This study presents a novel implantable drug delivery systemwith a biodegradable poly(caprolactone) membrane and compressed drug core forsustained release. These implantable devices deliver risperidone in vitro for 170 days and in vivo for 49 days in rats, showing promise for chronic conditions like schizophrenia.

Synthesis of C-5" and C-6"-modified α-GalCer analogues as iNKT-cell agonists [PDF]

open access: yes, 2015
Alpha-Galactosyl Ceramide (α-GalCer) is a prototypical synthetic ligand of invariant natural killer T (iNKT) cells. Upon presentation by the MHC class I-like molecule CD1d, this glycolipid stimulates iNKT cells to secrete a vast amount of both pro ...

Dexamethasone Delivery via Amphiphilic, Low‐swelling Hydrogels Treats Postoperative Inflammation in Cervical Spine Applications

open access: yesAdvanced Healthcare Materials, Volume 14, Issue 7, March 14, 2025.
DexaPatch, an implantable, low‐swelling amphiphilic hydrogel system containing dexamethasone‐PLGA microparticles, is developed and characterized for sustained local steroid release to reduce postoperative inflammation in tight surgical spaces. DexaPatch significantly reduces postoperative edema and fibrosis in a rabbit model of anterior spinal surgery,

Biomimetic Glycosaminoglycan‐Analog Hydrogel for Improved Embolization of Aneurysms: Environment‐Selective Swelling

open access: yesAdvanced Healthcare Materials, EarlyView.
Biomimetic glycosaminoglycan analog hydrogels exhibit suitable and robust mechanical properties, as well as hemocompatibility and biocompatibility, making them ideal for the embolization of intracranial aneurysms. Notably, the hydrogel's environment‐selective swelling properties enable complete blockage of the aneurysm cavity while preventing ...

Biologically Active Compounds. II. The Synthesis of β-CarboxY-γ-butyrolactone Derivatives [PDF]

open access: yes, 1968
Amide derivatives of γ-substituted paraconic and aconic acids have been synthesized. Ultraviolet spectra of the aconic acid derivatives showed characteristic fine structure in the region of 245 to 280 ...

Pyrophosphate‐Containing Calcium Phosphates Negatively Impact Heterotopic Bone Quality

open access: yesAdvanced Healthcare Materials, EarlyView.
The role of calcium pyrophosphate (Ca‐PP) in heterotopic bone formation and material degradation is investigated using calcium phosphate (CaP) compositions with varying Ca‐PP content. Results show that Ca‐PP does not impede heterotopic bone formation, minimally affects CaP degradation at non‐osseous sites, and increases phagocytosis.

Silylation of Carbohydrate Syrups [PDF]

open access: yes, 1979
Introduction Carbohydrates are usually difficult to analyze in solutions. Gas chromatography provides a suitable means for analysis. However most carbohydrate compounds are not volatile enough for use by this method.

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

open access: yesAdvanced 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.
