Enhanced Flame Retardancy and Mechanical Properties of Thermoplastic Vulcanizate by a Multi‐Piperazine/Melamine Vinylphosphonate System

Safety Science and Technology, EarlyView.
Novel vinyl‐containing intumescent flame retardants NV and MV were applied to TPV. The optimized 6NV/4MV system forms dense char layers to boost fire safety, and maintain mechanical performance without compatibilizers. ABSTRACT To meet the dual demands for flame retardancy and mechanical performance of thermoplastic vulcanizate (TPV), two ...

Probing skin photoallergens in reconstructed human epidermis: An EPR spin trapping investigation

Photochemistry and Photobiology, Volume 101, Issue 2, Page 275-281, March/April 2025.
We present an original proof‐of‐concept methodology to probe radical generation from allergens in contact with photoexposed skin, using electron paramagnetic resonance and spin trapping in a reconstructed human epidermis model mimicking real‐life exposure scenarios.

Advances in organic UV filters for sunscreens over the past decade

Photochemistry and Photobiology, EarlyView.
Highlighted organic UV filter frameworks that have been described for sunscreens over the past decade divided into three groups: derivatives of or inspired by approved organic UV filters, natural product‐based compounds, and miscellaneous. Abstract Ultraviolet (UV) radiation is a major environmental factor in photoaging, erythema, and skin cancer ...

Thermo‐tone: A newly revealed mechanism of blood flow regulation

Experimental Physiology, EarlyView.
Abstract Myogenic tone enables dynamic control of tissue blood flow. This intrinsic property of vascular smooth muscle cells to sense stretch and reflexively adjust the calibre of small arteries is crucial to maintain capillary pressure and a blood flow reserve. For over 120 years blood pressure was considered the sole determinant of myogenic tone. Our

Electrophysiological properties of the dorsal motor nucleus of the vagus motoneurones controlling airway mucus secretion in rats

The Journal of Physiology, EarlyView.
Abstract figure legend Acidosis depolarises parasympathetic respiratory motoneurones in the dorsal motor nucleus of the vagus (DMV) and increases their firing frequency by reducing TWIK‐2 channel conductance. Acidosis also activates astrocytes, which further enhance neuronal excitability through NMDA receptor‐dependent glutamatergic signalling.

Design, Synthesis and Molecular Docking Studies of Some Novel Hydrazone Derivatives Based on Trimetazidine as Selective and Potent AChE Inhibitors

Drug Development Research, Volume 87, Issue 7, November 2026.
ABSTRACT Alzheimer's disease (AD) is a progressive neurodegenerative disease, and cholinergic dysfunction is considered one of the fundamental pathological factors of this disease. Guided by the clinically used acetylcholinesterase (AChE) inhibitor donepezil, we explored trimetazidine dihydrochloride as an accessible starting scaffold to generate ...
