Copper Complexes with Arylated Triethylenetetramine Ligands: Reactivity Toward Dioxygen and Peroxides

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
Here, we describe new Cu(I)/Cu(II) complexes based on arylated tren ligands and investigate their reactivity toward O2 and peroxides. Low‐temperature–stopped flow studies revealed the formation of transient copper–oxygen species, including superoxido, hydroperoxido, and alkylperoxido intermediates.

Antioxidant Activity and Inhibition of Carbohydrate Hydrolyzing Enzymes by Underutilized Parts From Some Plant‐Based Foods and Their Effect on Postprandial Hyperglycemia

open access: yesFood Chemistry International, EarlyView.
The underutilized parts viz: pawpaw seed, banana, plantain, and potato peels showed promising antioxidant and inhibition of α‐amylase and α‐glucosidase activities (IC50 values ≤ 100 μg/mL). Similarly, pawpaw seed, banana, plantain, and potato peels reduced postprandial hyperglycemia in sucrose‐ and maltose‐induced hyperglycemia in rats.

Phenolic Profiles, Antioxidant Properties and Predicted Glycaemic Index of Bread Sweetened With Date Syrup in Comparison With Granulated Sugar

open access: yesFood Chemistry International, EarlyView.
Date syrup are used as sweetener in bread. Bread with date syrup had superior phenolic composition, better antioxidant properties and carbohydrate hydrolysing enzymes while bread with granulated sugar had higher predicted glyceamic index. The study concluded that date syrup could be the next though‐out ingredient for dual purpose in bread. ABSTRACT The

Pharmacological effects of gastrodin: Insight into neurological diseases and mechanism in ferroptosis and pyroptosis

open access: yesIbrain, Volume 11, Issue 1, Page 74-83, Spring 2025.
Pharmacological effects of gastrodin include prevention and treatment of cognitive decline and reperfusion injuries, anticonvulsion, antiepilepsy, antidepressants, and analgesia, which are related to antiferroptosis and antipyroptosis. Abstract Gastrodin, as an effective monomer of gastrodia elata, plays a significant role in anti‐inflammatory ...

SUMOylation regulates tumorigenesis and progression: Molecular mechanisms and therapeutic applications

open access: yesInterdisciplinary Medicine, EarlyView.
SUMOylation, a dynamic post‐translational modification, acts as a master regulator at the heart of tumor malignancy. Our work delineates how the SUMOylation cycle—mediated by E1/E2/E3 enzymes and reversed by SENPs—orchestrates multiple hallmarks of cancer. The central pathway converges on three critical pathological axes: 1.

Evaluating the Endocrine‐Disrupting and Oxidative Stress Potential of a 50‐Component Human‐Relevant Complex Chemical Mixture Using In Vitro Tests

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT Humans are chronically exposed to mixtures of environmental contaminants. Exposure to endocrine‐disrupting chemicals (EDCs) contributes to increased health impairment observed globally. This study aimed to evaluate the endocrine‐disruptive and oxidative stress potential of a human‐relevant, complex chemical mixture in vitro.

Subchronic Exposure to Arsenic and Nickel Triggers Nitrosative Stress and Histological Alterations in the Rat Liver

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT Environmental exposure to heavy metals poses a threat to human health. Several studies documented harmful effects on the liver after arsenic and nickel exposure at concentrations beyond permissible limits. Nevertheless, the impact of a simultaneous exposure to both elements on hepatic biochemistry and histology remains unelucidated. Therefore,

On‐site pilot‐scale advanced oxidation pretreatment of hospital wastewater: assessment of pharmaceuticals, pathogens, antibiotic resistance genes and acute ecotoxicity

open access: yesJournal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND Hospital premises generate wastewater containing a wide spectrum of contaminants, such as pharmaceutically active compounds (PhACs), antibiotic resistance genes (ARGs) and pathogenic microorganisms, whilst plenty of them are classified under the antibiotic resistant bacteria (ΑRΒ) category.

Method Based on Continuous Artificial Dry and Humid UV Treatments to Reduce the Luminescence Background in the Raman Spectra of Plastics

open access: yesJournal of Raman Spectroscopy, EarlyView.
We propose an UV photobleaching pretreatment to reduce the strong luminescence in the Raman spectra of plastic samples. Our protocol proves its efficiency whatever the luminescence origin (from the pigments or from a surface biofilm) but requires a careful optimization of the illumination conditions (UV wavelength, time, humidity) to reach the ...
