A Chiral Virus‐Like Nanoplatform That Broadly Mediates Antibiotic Delivery to the Brain for Bacterial Meningitis Therapy

Advanced Science, EarlyView.
Chiral virus‐mimicking mesoporous silica nanostructures (CVSNs) efficiently transport diverse antibiotics across the blood–brain barrier (BBB) into brain parenchyma and cerebrospinal fluid. By enhancing delivery to microglia and astrocytes, CVSNs improve antibiotic bioavailability and therapeutic efficacy against both Gram‐negative and Gram‐positive ...

Inhibition of calcium phosphate precipitation by bile salts: a test of the Ca(2+)-buffering hypothesis.

Journal of Lipid Research, 1994
The ability of bile salts to inhibit the precipitation of either calcium hydroxyapatite or its precursor, amorphous calcium phosphate, by reducing Ca2+ activity or poisoning nascent crystals was determined.

Polyphosphate Copper Nanospheres Drive Mitochondrial Metabolic Reprogramming via Calcium Phase Separation for Self‐Sensitizing Cuproptosis

Advanced Science, EarlyView.
This study developed polyphosphate (polyP)‐based nanostructures that enable calcium‐mediated metabolic reprogramming via liquid–liquid phase separation (LLPS). Released polyP undergoes LLPS with Ca2+, suppressing glycolytic flux and enhancing mitochondrial metabolism effectively.

A Programmable Braided Silk‐Glass Fiber Ligament Promoting Rapid Motoric Recovery

Advanced Science, EarlyView.
A scalable three‐dimensional braiding strategy integrates silk and glass fibers into customizable artificial ligaments with programmable “J‐shaped” nonlinear mechanics. The silk‐rich architecture supports osseoligamentous integration, while glass fibers provide mechanical reinforcement and biomimetic mineralization cues, enabling strain‐adaptive load ...

Effect of Casein Phosphopeptide-Amorphous Calcium Phosphate and Three Calcium Phosphate on Enamel Microhardness

The Journal of Contemporary Dental Practice, 2017
ABSTRACT Aim This study aims to investigate the effect of casein phosphopeptide-amorphous calcium phosphate and three calcium phosphate (CPP-ACP and TCP) on increasing the microhardness of human enamel after induction of erosion. Materials and methods A total of 26 healthy human-impacted third molar teeth were chosen, and their hardness measured ...

Hydrodynamic Selection of Polymorphic Assembly Pathways in Plant Protein Amyloid Fibrils

Advanced Science, EarlyView.
Hydrodynamic conditions are revealed to govern polymorphic assembly of soy protein amyloid fibrils. Distinct flow‐induced drafting, kissing, and docking dynamics direct fibril growth into multiple morphologies, linking fluid mechanics with nanoscale assembly and enabling rational design of functional amyloid materials.

31P Solid‐State NMR‐Enabled Development of a Pt/Aluminum Tripolyphosphate Catalyst for Selective C─O Bond Hydrogenolysis of Phenols

Angewandte Chemie, EarlyView.
31P solid‐state nuclear magnetic resonance analysis revealed the presence of aluminum tripolyphosphate on the surface of a platinum/aluminum condensed phosphate mixture (ACPM) catalyst. This finding led to the development of a Pt/aluminum tripolyphosphate (Pt/ATPP) catalyst for the selective hydrogenolysis of phenols to arenes.
