Microbiome‐blood–brain barrier interactions in aging — mechanisms and therapeutic potential

open access: yesFEBS Letters, EarlyView.
Aging reshapes the gut microbiome (↓SCFA‐producing commensals; ↑pro‐inflammatory outputs), shifting circulating metabolites (↓SCFAs; ↑LPS, ↑TMAO, ↑PAA) that act at the BBB to increase nonspecific transcytosis, alter transport, and promote astrocyte reactivity, heightening brain vulnerability.

Arc-based directed energy deposited Inconel 718: role of heat treatments on high-temperature tensile behavior

open access: yesMaterials Research Letters
This study evaluated the effect of dedicated heat treatments (1050°C, 1100°C, 1142°C, and 1185°C/2 h + double-aging) on the uniaxial tensile properties at elevated temperature (650°C) of Inconel® 718 fabricated via arc plasma directed energy deposition ...

Effect of natural aging time on tensile and fatigue anisotropy of extruded 7075 Al alloy

open access: yesJournal of Materials Research and Technology, 2022
In this study, 7075 Al alloy was prepared by solution treatment + natural aging. The anisotropic behavior of 7075 Al alloy in extrusion direction (ED), 45° direction (45°) and radial direction (RD) was studied by quasi-static tensile test and strain ...

Gut microbiota alterations in patients with non‐small‐cell lung cancer undergoing chemoradiotherapy

open access: yesMolecular Oncology, EarlyView.
We investigated the impact of concurrent chemoradiotherapy (CRT) on the gut microbiota in patients with locally advanced non‐small‐cell lung cancer. Overall gut microbiota composition remained largely stable throughout CRT while antibiotic exposure may influence microbial diversity.

FORMABILITY OF AUSTENITIC STAINLESS STEEL 316 SHEET IN DYNAMIC STRAIN AGING REGIME

open access: yesActa Metallurgica Slovaca, 2014
Dynamic strain aging region for austenitic stainless steel 316 was investigated from room temperature to 650°C at constant strain rates of 1x10-2, 1x10-3 and 1x10-4 sec-1.

On the Potential Correlation between Dynamic Strain Aging and Liquid Metal Embrittlement in T91/LBE System

open access: yesMetals, 2023
In the study of the liquid metal embrittlement (LME) of the T91/lead-bismuth eutectic (LBE) system, it is observed that LME occurs in a temperature interval which is similar to the temperature range where dynamic strain aging (DSA) is observed.

DYNAMIC STRAIN AGEING IN LiF SINGLE CRYSTALS [PDF]

open access: yesLe Journal de Physique Colloques, 1973
Dislocation-point defect interactions have been investigated in high purity LiF single crystals containing less than 5 ppm of Mg2+, utilising dynamic strain ageing techniques. Two mechanisms of strain ageing have been found. Below 200 °C, the mechanism is one of weak pinning of dislocations by tetragonal strain fields around impurity-vacancy dipoles ...

Dynamic tensile properties of mild steel sheets after strain aging

open access: yes, 2009
The dynamic behavior of ultra low carbon mild steels was experimentally examined in order to know the contribution of the pure ferrite phase on the strain rate sensitivities.

Reprogramming tumor cells with LCOR mRNA nanotherapy to enhance immunotherapy

open access: yesMolecular Oncology, EarlyView.
LCOR (Ligand‐dependent corepressor) mRNA encapsulated in polymeric nanoparticles restores LCOR activity in tumor cells, constraining aggressive tumor cell states and increasing tumor immunogenicity. This reprogramming makes tumor cells more vulnerable to T‐cell attack and enhances their response to immune‐checkpoint immunotherapy.
