Modulatory Role of Melatonin in Cyclophosphamide‐Treated Platelets: Insights From Ex Vivo Oxidative Stress Model

open access: yesJournal of Biochemical and Molecular Toxicology, Volume 40, Issue 9, September 2026.
Cyclophosphamide (CYP) alters the redox status in platelets, resulting in oxidative damage and platelet dysfunction as a result of oxidative stress. Melatonin plays a protective role and mitigates the CYP‐induced oxidative stress by directly scavenging ROS and augmenting the antioxidant defenses.

A recently evolved hexose transporter variant confers resistance to multiple pathogens in wheat [PDF]

open access: yes, 2015
As there are numerous pathogen species that cause disease and limit yields of crops, such as wheat (Triticum aestivum), single genes that provide resistance to multiple pathogens are valuable in crop improvement(1,2).

Integrated pretreatment and fermentation strategies for L‐lactic acid production from brewers' spent grain using native Streptococcus infantarius and Bacillus coagulans

open access: yesJournal of Chemical Technology &Biotechnology, Volume 101, Issue 9, Page 1869-1876, September 2026.
Abstract BACKGROUND Brewers' spent grain (BSG) is an abundant lignocellulosic byproduct of the brewing industry with strong potential as a renewable substrate for biotechnological production of lactic acid (LA). This study evaluated integrated pretreatment, enzymatic hydrolysis, and fermentation strategies to enable efficient production of optically ...

Cross‐Species Plasticity and Divergence Under Alkaline Soil Signature Conditions Differentiating PYE From FIT Target Transcripts in the Arabidopsis thaliana Ferrome

open access: yesPlant, Cell &Environment, Volume 49, Issue 9, Page 6719-6736, September 2026.
ABSTRACT Soil pH is an influential abiotic environmental factor. Here, we identify responses to central stimuli associated with calcareous alkaline soils in Arabidopsis and comparatively explore the potential of the closely related Arabidopsis halleri for addressing how plants cope with local soil pH.

Oral PHGG ameliorates atopic dermatitis‐like dermatitis with concurrent modulation of colonic IgA and cecal microbiota: implications for the gut–skin axis

open access: yesJournal of the Science of Food and Agriculture, Volume 106, Issue 11, Page 6380-6394, 30 August 2026.
Abstract BACKGROUND Atopic dermatitis (AD) is increasingly recognized as a systemic inflammatory disorder linked to intestinal immune and microbiome dysregulation. However, whether dietary galactomannan fibers can mitigate AD through coordinated modulation of the gut–skin axis remains unexplored.

A MassQL‐Based Framework for Rule‐Guided MS/MS Class‐Level Retrieval and Analog Discovery of Cannabinoids

open access: yesRapid Communications in Mass Spectrometry, Volume 40, Issue 16, 30 August 2026.
ABSTRACT Rationale Cannabinoids comprise a chemically diverse group of meroterpenoids whose extensive isomerism, variable side‐chain length, and frequent oxidative or rearranged derivatives lead to strongly overlapping yet characteristic MS/MS fragmentation patterns. In untargeted LC–MS/MS datasets, this combination of structural diversity and spectral

Cobalamin‐Dependent O‐Demethylation of Polymethoxyflavones by Enzymes Isolated From the Human Gut Microorganism Blautia producta MRG‐PMF1

open access: yesAdvanced Synthesis &Catalysis, Volume 368, Issue 16, 18 August 2026.
O‐demethylation of aryl methyl ethers is an invaluable transformation, playing a critical role in ecological circulation by degrading abundant lignin‐derived compounds and other natural products. Chemical O‐demethylation requires harsh reaction conditions; thus, the need for biocatalytic solutions is of high interest.

Acid Sulfite Pulping of Hemp: Effects of Processing Conditions on Lyocell Pulp Quality

open access: yesJournal of Polymer Science, Volume 64, Issue 16, Page 3364-3381, 15 August 2026.
Industrial hemp is emerging as a promising renewable source for next‐generation textile fibers. This study evaluates whether acid sulfite pulping can produce hemp‐based dissolving pulp suitable for lyocell manufacturing. While the process is historically linked to increased cellulose accessibility, it did not achieve the low lignin content and ...
