Acute and Chronic Toxicity of Sediments Containing Platinum and Palladium on Freshwater Benthic Organisms Chironomus riparius and Hyalella azteca

Journal of Applied Toxicology, Volume 46, Issue 4, Page 1151-1163, April 2026.
ABSTRACT The expanding demand for platinum group elements (PGEs) in industrial and medical applications has led to their increasing accumulation in aquatic sediments. However, their ecological impacts remain poorly understood, particularly for sediment‐dwelling invertebrates. This study assessed the toxicity of platinum (Pt) and palladium (Pd) across a

3‐Methyl‐1‐Butanol Enhances Postharvest Resistance of Red Grapes to Botrytis cinerea by Activating Phenylpropanoid Metabolism and Antioxidant Defences

Plant Biotechnology Journal, Volume 24, Issue 4, Page 2673-2684, April 2026.
ABSTRACT Grey mould, caused by Botrytis cinerea, is a significant postharvest disease leading to substantial economic losses in the grape industry. This study investigated the regulatory mechanism of 3‐methyl‐1‐butanol (3M1B), a yeast volatile substance, on B. cinerea resistance in red grapes (Vitis vinifera L.).

Stimuli‐responsive hydrogels: An intelligent tool for wound management

Interdisciplinary Medicine, Volume 4, Issue 2, March 2026.
For chronic and complex wounds, this review focuses on intelligent hydrogels capable of responding to wound microenvironmental cues (e.g., pH, enzymes) or external stimuli (e.g., light, electricity). These advanced materials enable the dynamic regulation of drug release and real‐time monitoring of healing progression, thereby offering innovative ...
