Microglial dynamics and ferroptosis induction in human iPSC‐derived neuron–astrocyte–microglia tri‐cultures

FEBS Open Bio, EarlyView.
A tri‐culture of iPSC‐derived neurons, astrocytes, and microglia treated with ferroptosis inducers as an Induced ferroptosis model was characterized by scRNA‐seq, cell survival, and cytokine release assays. This analysis revealed diverse microglial transcriptomic changes, indicating that the system captures key aspects of the complex cellular ...

The Change in the Shape Characteristics of the Plastic Zone in the Surrounding Rock of an Auxiliary Retracement Channel and a Reasonable Channel Spacing Determination Method

Applied Sciences, 2023
In underground coal mines, the stability of the retracement channel in the surrounding rock is crucial for the safe and efficient retracement of the equipment and to guarantee the continuity of the retracement work.

Athermal Shear-Transformation-Zone Theory of Amorphous Plastic Deformation I: Basic Principles

, 2006
We develop an athermal version of the shear-transformation-zone (STZ) theory of amorphous plasticity in materials where thermal activation of irreversible molecular rearrangements is negligible or nonexistent.

Plastic Deformation Zone in Electromagnetic Cutting [PDF]

Archives of Metallurgy and Materials, 2017
AbstractThis paper presents the application of the electromagnetic field as a tool for metal sheet cutting. The experiments showed that one can easily adapt the conventional cutting equipment to the electromagnetic cutting technology and thereby eliminate the mechanical work of the punch and the press.

Revisiting Stability Criteria in Ball‐Milled High‐Entropy Alloys: Do Hume–Rothery and Thermodynamic Rules Equally Apply?

Advanced Engineering Materials, Volume 27, Issue 6, March 2025.
The stability criteria affecting the formation of high‐entropy alloys, particularly focusing in supersaturated solid solutions produced by mechanical alloying, are analyzed. Criteria based on Hume–Rothery rules are distinguished from those derived from thermodynamic relations. The formers are generally applicable to mechanically alloyed samples.

CAA-derived IL-6 promoted the PD-L1 expression of breast cancer via STAT3/miR-497a-5p signaling

Journal of Cancer Research and Clinical Oncology
Background Adipocytes are engaged in the development and progression of breast cancer (BC). Cancer-associated adipocytes (CAAs) are specific adipocytes located at the invasive front of BC that modulate tumor behaviors. This study aimed to investigate the

Rapid Landscape Changes in Plastic Bays Along the Norwegian Coastline

Frontiers in Marine Science, 2021
The Norwegian Coastal Current transports natural debris and plastic waste along the Norwegian coastline. Deposition occurs in so-called wreck-bays and includes floating debris, such as seaweed, driftwood and volcanic pumice, and increasing amounts of ...

Free-Boundary Dynamics in Elasto-plastic Amorphous Solids: The Circular Hole Problem

, 2006
We develop an athermal shear-transformation-zone (STZ) theory of plastic deformation in spatially inhomogeneous, amorphous solids. Our ultimate goal is to describe the dynamics of the boundaries of voids or cracks in such systems when they are subjected ...

Enhancing Corrosion Resistance and Mechanical Strength of 3D‐Printed Iron Polylactic Acid for Marine Applications via Laser Surface Texturing

Advanced Engineering Materials, EarlyView.
Laser surface texturing significantly improves the corrosion resistance and mechanical strength of 3D‐printed iron polylactic acid (Ir‐PLA) for marine applications. Optimal laser parameters reduce corrosion by 80% and enhance tensile strength by 25% and ductility by 15%.
