The Bree problem with different yield stresses on-load and off-load and application to creep ratcheting

open access: yes, 2014
The ratchet boundaries and ratchet strains are derived for the Bree problem and an elastic perfectly plastic material with different yield stresses on-load and off-load.

Acute caffeine treatment protects the developing retina from ischemia‐induced cell death

open access: yesFEBS Open Bio, EarlyView.
Caffeine reduces cell death in the developing retina under ischemia (OGD). This effect does not involve BDNF upregulation or antioxidant pathways (NRF2/VEGF). Neuroprotection occurs mainly through adenosine A2A receptor antagonism, decreasing glutamate release and excitotoxicity, highlighting caffeine's potential as an acute neuroprotective agent in ...

STRESS-REGULATED PROTOCOLS FOR FAST CHARGING IN LITHIUM-ION BATTERIES (MT)

open access: yesJixie qiangdu, 2023
Inspired by the intrinsic degradation mechanism within the battery during fast charging, a stress-regulation(SR) fast charging method for lithium-ion battery is proposed by considering the diffusion-induced stress in the positive active particles. In the

Thermoelastic stress analysis of laminated composite materials

open access: yes, 2009
In this work thermoelastic stress analysis (TSA) is used to obtain quantitative stress/strain data from a variety of multi-directional laminated composites. In order to interpret the thermoelastic signal correctly the source of the thermoelastic response

Weld residual stress effects on fatigue crack growth behaviour of aluminium alloy 2024-T351 [PDF]

open access: yes, 2008
The interaction between residual stress and fatigue crack growth rate has been investigated in middle tension and compact tension specimens machined from a variable polarity plasma arc welded aluminium alloy 2024-T351 plate.

Early‐life high‐fat diet exposure increases Achilles tendon stiffness and induces transcriptomic alterations

open access: yesFEBS Open Bio, EarlyView.
Early‐life exposure to a high‐fat diet altered intact Achilles tendons in rat offspring, making them thinner, stiffer, and molecularly distinct even without injury. These findings suggest that developmental high‐fat diet exposure may impair tendon quality and increase susceptibility to mechanical overload or tendon injury later in life.

Cyclic azapeptide CD36 ligand attenuates cardiac injury and reduces long‐chain fatty acid accumulation after myocardial ischemia–reperfusion in mice

open access: yesFEBS Open Bio, EarlyView.
In a murine model of myocardial ischemia and reperfusion (MI/R), the CD36 azapeptide ligand MPE‐298 reduces cardiac injury and transiently lowers left ventricular long‐chain fatty acids (LCFAs) accumulation 3 h after reperfusion, accompanied by a decrease of oxidative stress and inflammation‐associated genes' expression in the heart and adipose tissue.

Hydrostatic pressure activates HIF‐1α via β‐catenin to promote stemness in breast cancer cells

open access: yesFEBS Open Bio, EarlyView.
To mimic the elevated intestinal fluid pressure in breast cancers, we loaded human breast cancer cells (MCF‐7, MDA‐MB‐453, and BT‐474) to 50 mmHg hydrostatic pressure. Hydrostatic pressure exposure upregulated HIF‐1α and induced stemness in MCF‐7 and BT‐474 cells.
