Engineering Topographical Cues to Enhance Neural Regeneration in Spinal Cord Injury: Overcoming Challenges and Advancing Therapies

Advanced Functional Materials, EarlyView.
Spinal cord injury (SCI) poses significant challenges for regeneration due to a series of secondary injury mechanisms. How to use biomaterial approach to target the failed regeneration after SCI remains a critical challenge. This review systematically evaluates current strategies to optimize biomaterial topographies for neurite outgrowth, axonal ...

Approximate Arithmetic Training Improves Informal Math Performance in Low Achieving Preschoolers

Frontiers in Psychology, 2018
Recent studies suggest that practice with approximate and non-symbolic arithmetic problems improves the math performance of adults, school aged children, and preschoolers. However, the relative effectiveness of approximate arithmetic training compared to

Combination of Polydopamine and Plasma Oxidation to Increase Tissue Integration of Polyurethane‐Silicone Copolymers for Cardiovascular Implants

Advanced Healthcare Materials, EarlyView.
Plasma oxidation following polydopamine deposition can significantly reduce the surface hydrophobicity of polyurethane‐siloxanes without impacting surface roughness, thereby increasing fibroblast viability, adhesion, and extracellular matrix production and secretion.

Food insecurity and cognitive function in older adults: findings from the longitudinal aging study in India

BMC Psychiatry, 2023
Background As we grow older, food insecurity (FI) may have an impact on our cognitive abilities. The study examines the association of FI with the cognitive function of older adults in India.

Therapeutic Implants: Mechanobiologic Enhancement of Osteogenic, Angiogenic, and Myogenic Responses in Human Mesenchymal Stem Cells on 3D‐Printed Titanium Truss

Advanced Healthcare Materials, EarlyView.
This study investigates a synergistic effect between 3D‐printed surface features and mechanical micro‐strain in enhancing the osteogenic, angiogenic, and myogenic responses of human mesenchymal stem cells (hMSCs). Load‐induced mechanotransduction, facilitated by the implant's architectural design, significantly amplifies hMSC differentiation.

On Asymptotic Distributions of Arithmetical Functions [PDF]

Transactions of the American Mathematical Society, 1936
1. The present note was suggested by recent work of H. Davenport, [3 ],t S. Bochner and B. Jessen, [2 ], and A. Wintner and B. Jessen, [6 ]. Davenport established the existence of asymptotic distribution functions for a certain class of arithmetical functions by an extension of a method previously used by the author, [8], [9], in a similar ...

Active Fabric Origami Enabled by Digital Embroidery of Magnetic Yarns

Advanced Materials, EarlyView.
This study demonstrates a scalable textile manufacturing process that fabricates active origami fabrics (AFO) via digital embroidery of magnetic yarns. The programmable AFO exhibits reversible 2D and 3D transformations under magnetic fields, enabling functionalities such as altering surface roughness and linear actuation.

The Arithmetic of Hyperbolic Functions [PDF]

Nature, 1911
THROUGHOUT the books treating of hyperbolic functions, although elaborate series for their determination are given, the possibility of calculating them directly from their definitions, by means of common logarithms, is never suggested, and it would appear, therefore, that the merits of the direct method are insufficiently recognised.

Reduction of Micro‐Motion at the Tapered Connection of Hip Endoprostheses with an Adapted Deep Rolling Process of CoCrMo Inner Tapers

Advanced Materials Interfaces, EarlyView.
The ball burnishing processes demonstrated a notable reduction of surface roughness, which in turn helps to reduce the formation of wear particles and is reflected in the significantly reduced wear rate. The torsional resistance in the range of micro‐motion (≈2 Nm) can be improved by implementing a ball burnishing process with augmented depth hardness.

Biomechanical Performance of Additively Manufactured Bone‐Mimicking Scaffolds with Graded Architectures

Advanced Materials Technologies, EarlyView.
Nozzle temperature of 180 °C suits well for supportless PLA stochastic scaffolds. The scaffolds exhibit higher strength and stiffness under sudden impact loading. Grading type shows significant influence on scaffold properties. Radial descending type performs best in both mechanical and permeability aspects. Graded stochastic scaffolds are suitable for
