Investigation into the Synergistic Enhancement of Astaxanthin Nanodispersion Stability by Chitosan-Ca2+ and Its Underlying Mechanism

Shipin gongye ke-ji
To enhance the stability and bioavailability of astaxanthin (AST), soy protein isolates (SPI) were used as the raw material to prepare SPI/chitosan (CS) composite nanoparticles for the encapsulation of AST.

Reduced Graphene Oxide Enhances the Vascular Organization and Contractile Performance of Fibrin‐Gelatin‐Based Engineered Cardiac Tissue

Advanced Materials Interfaces, EarlyView.
Fibrin–gelatin hydrogels functionalized with reduced graphene oxide create a mechanically stable and bioactive 3D environment for engineered cardiac tissue. The composite matrix promotes endothelial lumen formation, enhances sarcomeric protein expression, and increases contractile performance of embedded cardiomyocytes.

Sustained Ca2+ transfer across mitochondria is Essential for mitochondrial Ca2+ buffering, sore-operated Ca2+ entry, and Ca2+ store refilling

, 2003
Mitochondria have been found to sequester and release Ca2+ during cell stimulation with inositol 1,4,5-triphosphate-generating agonists, thereby generating subplasmalemmal microdomains of low Ca2+ that sustain activity of capacitative Ca2+ entry (CCE ...

A Critical Review on the Evolution of Chitosan‐Based Injectable Hydrogels in Bone Regeneration

Advanced Materials Interfaces, EarlyView.
The graphical illustration depicts hydrogel formulation using chitosan and biocompatible cross‐linkers, major advantages, and incorporation of cells, osteoinductive factors, and therapeutic drugs. Following injection, pH‐responsive gelation enables controlled drug release, promotes cell recruitment and osteogenic differentiation, enhances extracellular

Na(+)-Ca2+ exchange and Ca2+ depletion in rat proximal tubules

, 1991
The removal of external Ca2+ ([Ca2+]o) reduces cytosolic Ca2+ ([Ca2+]i) in rat proximal tubules. In this report the role of external Na+ ([Na+]o) on the changes of [Ca2+]i and Ca2+ efflux caused by withdrawal of [Ca2+]o is described in rat renal ...

Smart‐Release Ion‐Exchanged Ca‐Montmorillonite for Corrosion Protection of AA2024 Aluminium Alloy

Advanced Materials Interfaces, EarlyView.
Smart‐release anticorrosion pigments based on Zn‐ and Mn‐modified montmorillonite were developed by ion exchange of Ca‐montmorillonite and evaluated for the protection of AA2024 aluminium alloy in artificial acid rain. Both modified pigments provided effective corrosion inhibition, with Zn‐modified montmorillonite (Zn‐MMT) achieving an inhibition ...
