Artificial Intelligences: A Bridge Toward Diverse Intelligence and Humanity's Future

Advanced Intelligent Systems, EarlyView.
Many discussions of artificial intelligence fail to address deeper questions being raised by advances in developmental biology, neuroscience, bioengineering, and philosophy of mind. Novel beings, including technologically and biologically augmented humans, engineered life forms, hybrots, and others, require tools of the emerging field of diverse ...

4D Printing of Polyethylene Glycol‐Grafted Carbon Nanotube‐Reinforced Polyvinyl Chloride–Polycaprolactone Composites for Enhanced Shape Recovery and Thermomechanical Performance

Advanced Intelligent Systems, EarlyView.
This study introduces polyethylene glycol‐functionalized carbon nanotubes (CNTs) to enhance dispersion, interfacial bonding, and 4D printability in polyvinyl chloride‐PCL nanocomposites. The optimized 4D composite (0.5 wt% CNT) achieves a 25% increase in tensile strength, 95.78% shape fixity, and 5‐s recovery time.

circNR3C2 promotes chondrogenic differentiation and cartilage repair of human adipose‐derived stem cells via the hsa‐miR‐647/SOX9 pathway

Animal Models and Experimental Medicine, EarlyView.
The hypothesis diagram illustrates the function and mechanism of circNR3C2: circNR3C2 overexpression can up‐regulate COL2, Aggrecan and SOX9 expression, and regulate chondrogenic differentiation of hADSCs by targeting hsa‐miR‐647. Abstract Background Human adipose‐derived stem cells (hADSCs) are seed cells with application prospects in cartilage repair.

Biocompatibility and healing patterns in experimentally induced canine tibial fractures using Pedicle screw‐Rod external fixation

Animal Models and Experimental Medicine, EarlyView.
This study demonstrates that using a Pedicle screw‐Rod configuration for the external fixation of non‐articular tibial osteotomy aligns well with the principles of biological osteosynthesis, resulting in secondary bone healing characterized by callus formation and neovascularization.

Design and Application of Piezoelectric Conductive Smart Scaffold for Noninvasive Neural Tissue Regeneration via Custom‐Made In Vitro Mechano‐Stimulator

Advanced NanoBiomed Research, EarlyView.
Schematic illustration showing the design of the developed invitro mechano stimulator (IMS) and the electrospun nanofiber‐based piezoelectric and conductive nerve conduit (PCNC) that can self‐generate electrical stimulations analogous to neural tissues. IMS provided vital electrical cues for the neural cells to attach, align and proliferate on the PCNC

Influence of Beta Tricalcium Phosphate Particles on In Vitro Material Degradation and Early Cell Attachment of MC3T3‐E1 Cells on Poly(3‐Hydroxybutyrate)/Poly(3‐Hydroxybutyrate‐Co‐4‐Hydroxybutyrate) Films

Journal of Applied Polymer Science, EarlyView.
Investigation of the influence of beta‐tricalcium phosphate incorporation on the degradation behavior of a PHA blend and MC3T3‐E1 cell attachment. ABSTRACT The influence of beta‐tricalcium phosphate (ß‐TCP) particles on the early cell attachment of MC3T3‐E1 osteoblast precursor cells is investigated on a poly(3‐hydroxybutyrate)/poly(3‐hydroxybutyrate ...
