Superior oxidation resistance in air during hot stamping of a coating-free press-hardened steel achieved by pre-oxidation

Journal of Materials Research and Technology
While coating-free press-hardened steel (CF-PHS) can prevent high-temperature oxidation during hot stamping, it requires high-purity nitrogen protection, which increases the operation cost.

EDNRB‐dependent endothelin signaling reduces proliferation and promotes proneural‐to‐mesenchymal transition in gliomas

Molecular Oncology, EarlyView.
Glioma cells mainly express the endothelin receptor EDNRB, while EDNRA is restricted to a perivascular tumor subpopulation. Endothelin signaling reduces glioma cell proliferation while promoting migration and a proneural‐to‐mesenchymal transition associated with poor prognosis. This pathway activates Ca2+, K+, ERK, and STAT3 signalings and is regulated

Crack growth resistance in nuclear graphite [PDF]

, 2002
R-curve behaviour is often used for evaluating crack growth resistance in quasibrittle materials but few studies have focused on polycrystalline graphite. In this study, R-curve behaviour in three commercial grade nuclear graphites, of varying structure

Oxidation resistance of Mo(Si1-xAlx)(2) nanocrystalline films and characterization of their oxide scales by electrochemical impedance spectroscopy

, 2014
To explore the influence of Al alloying on the oxidation resistance of MoSi2, four Mo(Si1-xAlx)(2) nanocrystalline films, with differing Al contents, were fabricated on Ti-6A1-4V substrates by a double-cathode glow discharge technique and their cyclic ...

Hippo pathway at the crossroads of stemness and therapeutic resistance in breast cancer

Molecular Oncology, EarlyView.
Dysregulation of the Hippo pathway drives nuclear accumulation of YAP/TAZ, activating stemness‐related transcriptional programs that sustain breast cancer stemness and fuel therapeutic resistance across subtypes, underscoring Hippo signaling as a targetable vulnerability. Figure created and edited with BioRender.com.

New perspectives on nutritional interventions to augment lipid utilisation during exercise [PDF]

, 2011
The enhancement of fat oxidation during exercise is an aim for both recreational exercising individuals and endurance athletes. Nutritional status may explain a large part of the variation in maximal rates of fat oxidation during exercise.

Resistance of nerve cells to oxidative injury

Medicinski pregled, 2011
Introduction. Reactive oxygen species are particularly active in the brain and neuronal tissue, and they are involved in numerous cellular functions, including cell death and survival. Brain and oxidative stress. A high metabolic rate and an abundant supply of the transition metals make the brain an ideal target for a free radical attack ...

Deciphering transcriptional plasticity in pancreatic ductal adenocarcinoma reveals alterations in sensory neuron innervation

Molecular Oncology, EarlyView.
Pancreatic sensory neurons innervating healthy and PDAC tissue were retrogradely labeled and profiled by single‐cell RNA sequencing. Tumor‐associated innervation showed a dominant neurofilament‐positive subtype, altered mitochondrial gene signatures, and reduced non‐peptidergic neurons.
