Stress–strain curve estimation from load–depth curve of spherical indentation test based on finite element analysis and optimization

Nuclear Engineering and Technology
A stress–strain curve is one of the most important indicators of material properties for characterizing constitutive behavior. It can be directly obtained from a conventional uniaxial tensile test or load–displacement curve using an instrumented ...

Phosphoinositides and inositol phosphates as molecular glues

FEBS Letters, EarlyView.
Inositol phosphates (IPs) and phosphoinositides (PIPs) regulate diverse eukaryotic processes. Beyond recruiting signaling proteins or acting as structural cofactors, recent studies suggest they mediate protein–protein interactions as natural molecular glues.

Typical stress-strain curve.

, 2014
(1) y = 0, when x = 0. The stress-strain curve passes the origin. (2) , when x = 0. The slope of the curve at the origin is equal to the dimensionless linear elastic modulus of the root. (3) y = 1, when x = 1. The peak stress happens x = 1. (4) 0, when x

Scaffolds with a Tunable Nonlinear Elastic Region Using a Corrugated Design

Small Structures
Elastin is the main component of arteries and is responsible for their high‐elastic high‐strain capacity. The biomechanics of biological tissues typically display a stress–strain curve characterized by a sigmoidal shape that has an initial region with ...

Strain Rate Impact into the Stress and Strain Values at Break of the PA6 GF30-Reinforced Polyamides

Applied Sciences
The study of the strain rate effects on the PA6 glass fiber-reinforced polyamide, in this specific case, PA6 GF30 (30% reinforced glass fiber), is critical due to composites widely used in automotive applications where the velocity of loading can vary ...

PARK(ing) time–How park deficiency affects the biological clock in a Drosophila model of Parkinson's disease

FEBS Letters, EarlyView.
Drosophila park mutants serve as a model for Parkinson's disease. We used this strain to investigate the connection between oxidative stress and the circadian clock mechanism. We showed that increased oxidative stress affects the physiology of pacemaker cells, disrupting their daily structural plasticity. Lack of rhythmic signaling from pacemaker cells

Mixed‐class J‐domain protein scaffolds promote expanded aggregate handling and multivalent Hsp70 engagement during functional disaggregase assembly

FEBS Letters, EarlyView.
Protein aggregates threaten proteostasis and cell health. In human cells, Hsp70–J‐domain protein‐based disaggregases remove aggregates, but how they assemble remains unclear. Our biochemical findings show that DNAJA2‐ and DNAJB1‐containing disaggregase scaffolds enhance luciferase aggregate targeting, and that Hsp70 recruitment by both J‐domain ...
