Oxidative Stress in Aging Human Skin

Biomolecules, 2015
Oxidative stress in skin plays a major role in the aging process. This is true for intrinsic aging and even more for extrinsic aging. Although the results are quite different in dermis and epidermis, extrinsic aging is driven to a large extent by ...

Beneficial Role of Natural Polyphenols Against Epilepsy: Greasing the Wheels of Pharmacotherapy Research for Epilepsy

Food Frontiers, Volume 7, Issue 6, November 2026.
ABSTRACT Epilepsy is the most disabling neurological disease that affects all economic classes, age groups, regions, and races. Although many antiseizure drugs are approved for epilepsy treatment, they fail to work in about 30%–40% of patients. Thus, there is a great need to identify better pharmacological agents to treat epilepsy.

Visible‐Light‐Initiated, Nickel‐Catalyzed Aminocarbonylation of Alkynyl Iodides to 2‐Ynamides

Advanced Synthesis &Catalysis, Volume 368, Issue 19, 1 October 2026.
Visible light initiates a nickel‐catalyzed aminocarbonylation of alkynyl iodides, enabling the synthesis of 2‐ynamides under low carbon monoxide pressure. The method operates under mild conditions, tolerates a broad substrate scope, and proceeds through a light‐triggered nickel(I)/nickel(III) carbonylative pathway.

Facet‐Dependent Activity of Fe3S4 Crystal in Peroxydisulfate Activation for Organic Pollutants Degradation

Advanced Science, Volume 13, Issue 56, 9 October 2026.
Fe3S4 crystal with the exposed [001] facet exhibits higher catalytic activity for activating peroxydisulfate (PDS) to degrade clothianidin (CLO), which can be attributed to the dissolved Fe‐induced homogeneous catalytic process; while Fe3S4 crystal with the exposed [1‐21] facet exhibits excellent catalytic stability and durability, thereby boosting the
