Move beyond free radical theory of aging

open access: yesiMetaOmics, EarlyView.
Free radicals play a dual, dose‐dependent role in aging. Low levels activate the key sensor adenosine 5'‐monophosphate‐activated protein kinase (AMPK), promoting cell survival mechanisms like autophagy and enhancing mitochondrial health. High levels, however, push AMPK to initiate cell death pathways, such as apoptosis. This positions AMPK as a central

Structural design and property regulation of organic polymers for photocatalytic synthesis of H2O2

open access: yesInfoScience, EarlyView.
Photocatalytic synthesis of H2O2 offers a sustainable approach. Photocatalytic efficiency depends critically on interfacial electron transfer kinetics and spatial charge separation. Herein, we systematically analyze key factors governing photogenerated carrier dynamics and propose engineered strategies to optimize performance, thereby providing design ...

Evaluation of antifungal and antimycotoxigenic activity of selected natural antioxidants against Fusarium culmorum: in vitro and in planta assays

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Fusarium culmorum causes Fusarium head blight (FHB) in cereals, leading to significant yield losses and contamination with type B trichothecene mycotoxins such as deoxynivalenol (DON) and its acetylated derivatives 3‐ADON and 15‐ADON.

Development of an Insulin‐Permeable Hydrogel Membrane Based on Photocrosslinkable Poly(2‐Alkyl‐2‐Oxazoline)s

open access: yesMacromolecular Materials and Engineering, EarlyView.
Hydrogel‐based composite membranes from photocrosslinkable poly(2‐alkyl‐2‐oxazoline) layers on PET meshes are presented as an insulin‐permeable barrier in delivery platforms for potential use in wound treatment. The membrane design addresses the challenge of maintaining protein structural integrity during topical delivery through polymeric hydrogel ...
