Bio‐Inspired Synthesis of Macroporous Single Crystal Particles as Scattering Agents

Advanced Functional Materials, EarlyView.
A general strategy is presented that delivers unique, single‐crystal microparticles that combine submicron macroporosity and uniform particle shapes. A bioinspired approach is used to occlude three distinct types of additives – polystyrene microspheres, polymer vesicles and amino acids – within calcite single crystals, and subsequent thermal annealing ...

Optimization of allogeneic mesenchymal progenitor cells for posterolateral spinal fusion with posterior instrumentation in sheep [PDF]

, 2007
Autologous bone is a finite resource and harvesting is associated with significant morbidity. This study investigated the safety and efficacy of allogeneic mesenchymal progenitor cells (MPCs) delivered via a calcium phosphate carrier to stimulate bone ...

Coordinated Architectural and Chemical Reinforcement in the Crushing Mandible of a Soldier Termite

Advanced Functional Materials, EarlyView.
The crushing mandible of a soldier termite withstands substantial biting loads despite lacking mineral. Its cuticle is partitioned: convex teeth pair hardness and zinc enrichment with aligned chitin fibers for contact durability, while stiffer concave regions between teeth carry bending loads.

Thermoresponsive Soft and Self‐Anchoring Cuff Electrode for Chronic Peripheral Interfaces

Advanced Functional Materials, EarlyView.
A novel thermoresponsive, soft and self‐anchoring (TSSA) cuff electrode utilizing shape memory polymers achieves autonomous, sutureless peripheral nerve fixation. Driven by thermally induced pre‐strain and tissue adhesion, the device self‐closes and softens at body temperature, successfully minimizing mechanical mismatch. This adaptive platform ensures

An Epigenetic Fate Converter Based on Nuclei‐Targeting Lipid Nanoparticles Drives Neuronal Programming of Stem Cells for Spinal Cord Repair

Advanced Functional Materials, EarlyView.
Schematic illustration of LNP‐MPG nuclei‐targeting delivery of HMW‐FGF2 promoting histone acetylation to regulate the fate of DPSCs and treat spinal cord injury. LNPs components include pHMW‐FGF2 plasmid, DSPC, Dlin‐MC3‐DMA, cholesterol, and PEG2000, and are modified with MPG to form HMW‐FGF2@LNP‐MPG (HLM). HLM nuclei‐targets DPSCs to deliver HMW‐FGF2,

Studies on D-3^He Fusion in LHD [PDF]

, 1996
In LHD ( Large Helical Device ) studies on realization of D-D fusion burning has been carried out, where tritium burning is out of this plan. We propose experiments on D-^3He fusion in this plan. This fueled fusion has the reaction cross-section as large

Zebrafish Magnetite and Long-lived Rohon-Beard Neurons: Expanding Our View of Two Zebrafish Sensory Systems in Development and Adulthood [PDF]

, 2012
During embryogenesis, the central nervous system (CNS) transforms from what seems like an amorphous mass of cells to a rod-like structure, and then to a fully functional and complex system of tissues composed of multiple cell types. Using confocal laser
