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.

AI‐Driven Predictive Design and Functionalization of Three Dimensional‐Printed PEEK Implants with Tryptophan‐Enriched Alginate Hydrogel for Enhanced Biomimetic Surface Performance

Advanced Intelligent Systems, EarlyView.
This study introduces an AI‐guided strategy to design 3D‐printed PEEK implants functionalized with a tryptophan‐enriched alginate hydrogel (TRYALPEEK). The modification improves hydrophilicity, reduces surface roughness, enhances cytocompatibility, and optimizes stress distribution. The platform offers a promising route for personalized implant design,

Tissue‐Resident Myeloid and Histiocytic Cells in Health and Disease: Novel Emerging Concepts

American Journal of Hematology, EarlyView.
ABSTRACT Although all myeloid cells are considered to derive from hematopoietic stem cells, the cells in each myeloid lineage are heterogeneous populations, and their distribution and functions vary, depending on underlying physiologic and pathologic processes, age, sex, and genetic and epigenetic signatures.

Effect of Heating Temperature on Wear Rate, Tensile Strength, and Crystallinity of Cantula Fiber-Reinforced Magnesium/Hydroxyapatite/ Shellac for Bone Screw Material

Mekanika
Bone screws are screws for bone that are joined to support plates. Bone screws generally use metal as the primary material because of its high mechanical properties, such as stainless steel and titanium.

Real World Study on the Best CPX‐351 Treatment Duration and Timing for Allogeneic Stem Cell Transplantation

American Journal of Hematology, EarlyView.
ABSTRACT In the registration clinical trial 301 (NCT01696084), CPX‐351 has shown to be superior to conventional 3 + 7 in secondary AML (s‐AML). However, the optimal duration of treatment, the best timing for allogeneic stem cell transplantation (allo‐HSCT), and the activity of CPX‐351 in specific s‐AML subgroups are unclear.
