Bacterial Cyclodipeptides Target Signal Pathways Involved in Malignant Melanoma

open access: yesFrontiers in Oncology, 2020
Melanoma is an aggressive cancer that utilizes multiple signaling pathways, including those that involve oncogenes, proto-oncogenes, and tumor suppressors. It has been suggested that melanoma formation requires cross-talk of the PI3K/Akt/mTOR and Ras-ERK

Directly Imprinted Porous Titania Metasurfaces Supporting Guided Mode Resonance and Quasibound States in the Continuum

open access: yesAdvanced Photonics Research, Volume 7, Issue 9, September 2026.
Direct nanoimprinting transforms mesoporous titania films into visible‐wavelength metasurfaces through a streamlined deposition‐and‐imprint process requiring no conventional lithography or etching. The resulting structures support pitch‐tunable guided‐mode resonances, symmetry‐controlled quasibound states in the continuum, structural‐color image ...

Liquid‐phase oxidation of furfural catalyzed by magnetically separable metal oxide nanoparticles deposited on silica gel

open access: yesBiofuels, Bioproducts and Biorefining, Volume 20, Issue 5, Page 2096-2105, September/October 2026.
Abstract Oxidation of furfural (FF), a bio‐based platform chemical, was investigated using a range of iron‐, vanadium‐ and iron–zinc‐oxalates supported on silica gel (FeVOx@silica and FeZnOx@silica, respectively) as precursor for FeV@silica and FeZn@silica oxide catalysts and H2O2 as a green oxidant.

A Dual Approach Combining Metal‐Organic Frameworks and Commercial Solid‐Phase Microextraction Coatings for Monitoring Volatiles in Passion Fruit

open access: yesJournal of Separation Science, Volume 49, Issue 9, September 2026.
A CIM‐80(Al) metal‐organic framework coating is proposed for the untargeted analysis of passion fruit juices using either headspace or direct immersion solid‐phase microextraction coupled with gas chromatography‐mass spectrometry. The CIM‐80(Al)‐coated fiber enabled the annotation of 14 unique compounds not detected with commercial fibers.

Acute and Chronic Effects of Green Tea Kombucha With and Without Grape Skin Extract on Immune and Oxidative Stress Markers in Beginner Runners: A Randomized Controlled Trial

open access: yesJournal of Food Science, Volume 91, Issue 9, September 2026.
ABSTRACT Green tea kombucha is an antioxidant‐rich beverage with promising health benefits. However, evidence regarding its effects in physically active individuals remains limited. This study investigated the acute and chronic effects of green tea kombucha, with or without grape skin extract, on immune and oxidative stress markers in beginner runners.
