A Human Neural Tube Model Using 4D Self‐Folding Smart Scaffolds

Advanced Healthcare Materials, EarlyView.
Induced pluripotent stem cells (iPSCs) exhibit features comparable to the inner cell mass of the human embryo. iPSCs are applied to a novel self‐folding 4D‐Neural Tube (4D‐NT) structure that mimics the neurulation process. This 4D‐NT model recapitulates early events of human neural development and represents a platform to explore neurodevelopmental ...

An adaptive greedy repair operator in a genetic algorithm for the minimum vertex cover problem

AIMS Mathematics
A genetic algorithm (GA) evolves the population of candidate solutions to a particular problem through crossover and mutation operators. Since a newly generated solution may not satisfy the constraints of the given problem, it is common to penalize ...

Layered Graphs: Applications and Algorithms

Algorithms, 2018
The computation of distances between strings has applications in molecular biology, music theory and pattern recognition. One such measure, called short reversal distance, has applications in evolutionary distance computation. It has been shown that this

Controlling Intestinal Organoid Polarity using Synthetic Dynamic Hydrogels Decorated with Laminin‐Derived IKVAV Peptides

Advanced Healthcare Materials, EarlyView.
Design rules are presented to control intestinal organoid polarity in fully synthetic hydrogels. The laminin‐derived IKVAV sequence is crucial to obtain correct intestinal organoid polarity. Increasing hydrogel dynamics further supports the growth of correctly polarized intestinal organoids, while a bulk level of stiffness (G’ ≈ 0.7 kPa) is crucial to ...

A Novel Microfluidic System for 3D Epidermis and Full‐Thickness Skin Growth for Nanoparticle Safety Assessment

Advanced Healthcare Materials, EarlyView.
This work presents a novel, dynamically perfused, configurable microfluidic system for epidermis‐only (E and full‐thickness skin (FT SoC) growth, emulating human skin structure and barrier function. Upon TiO2 nanoparticle exposure, the system reveals compromised barrier integrity, reduced metabolic activity, increased permeability, and chemokine‐driven

Ascorbic Acid Modulates Collagen Properties in Glucocorticoid‐Induced Osteoporotic Bone: Insights into Chemical, Mechanical, and Biological Regulation

Advanced Healthcare Materials, EarlyView.
Osteoporosis from long‐term glucocorticoid (GIOP) use elevates susceptibility to fracture. This study shows GCs impair ascorbic acid (AA) metabolism in osteoblasts, collagen synthesis and extracellular matrix integrity. AA enhanced collagen biochemical and mechanical properties and restored osteoblast and endothelial function. These findings underscore
