The Synergy of Artificial Intelligence and 3D Bioprinting: Unlocking New Frontiers in Precision and Tissue Fabrication

open access: yesAdvanced Functional Materials, EarlyView.
Advances in integrating artificial intelligence into 3D bioprinting are systematically reviewed here. Machine learning, computer vision, robotics, natural language processing, and expert systems are examined for their roles in optimizing bioprinting parameters, real‐time monitoring, quality control, and predictive maintenance.

Syntaxin 1B Suppresses Macropinocytosis and Semaphorin 3A-Induced Growth Cone Collapse

open access: yesJournal of Neuroscience, 2011
Growth cone collapse is a crucial process for repulsive axon guidance and is accompanied by a reduction in growth cone surface area. This process of reduction may be regulated by endocytosis; however, its molecular mechanism is unclear.

Engineering Hybrid Extracellular Vesicles for Functional mRNA Delivery

open access: yesAdvanced Functional Materials, EarlyView.
This study optimizes two methods for the generation of extracellular vesicle (EV)‐mimetic‐Lipid Nanoparticle (LNP) (CELLNPs) and EV‐LNP (HEVs) hybrid nanoparticles for messenger (mRNA) delivery. The authors screen lipid compositions to maximize hybrid nanoparticle formation and analyze the resulting nanoparticles with single particle characterization ...

Next‐Generation Bio‐Reducible Lipids Enable Enhanced Vaccine Efficacy in Malaria and Primate Models

open access: yesAdvanced Functional Materials, EarlyView.
Structure–activity relationship (SAR) optimization of bio‐reducible ionizable lipids enables the development of highly effective lipid nanoparticle (LNP) mRNA vaccines. Lead LNPs show superior tolerability and antibody responses in rodents and primates, outperforming approved COVID‐19 vaccine lipids.

Characterization of spontaneous calcium transients in nerve growth cones and their effect on growth cone migration

open access: yesNeuron, 1995
This study examines the mechanisms of spontaneous and induced [Ca2+]i spiking in nerve growth cones and the effect of spikes on growth cone migration. Over a 10-20 min observation period, 29% of DRG growth cones undergo spontaneous and transient elevations in physiological extracellular Ca2+ ((Ca2+)o; 2 mM), whereas 67% of growth cones exposed to 20 mM

Alginate‐Sludge Derived Biochar‐Calcium Hydrogel for Phosphate Removal and Slow‐Release Fertilizer: A Sustainable and Multifunctional Solution

open access: yesAdvanced Functional Materials, EarlyView.
An alginate‐based biochar hydrogel (ABC‐hydrogel), derived from sewage sludge, is developed for simultaneous phosphate removal and agricultural reuse. It captures phosphorus from water and gradually releases it as fertilizer, enhancing lettuce growth.

Liquid‐Locked Bassanites for Scalable Fabrication of High‐Temperature Micro‐Supercapacitors Working at 300 °C

open access: yesAdvanced Functional Materials, EarlyView.
A “liquid locking” strategy is proposed and implemented for scalable printing of crack‐free bassanite ceramic frameworks with interlocking microstructures to host ionic liquids as effective electrolytes for high‐temperature micro‐supercapacitors (HT‐MSCs).

Efficient simulations of tubulin-driven axonal growth

open access: yes, 2016
This work concerns efficient and reliable numerical simulations of the dynamic behaviour of a moving-boundary model for tubulin-driven axonal growth. The model is nonlinear and consists of a coupled set of a partial differential equation (PDE) and two ...
