Recreational Allergic Contact Dermatitis to “Epoxy UV” Resins: A New Source of Exposure to Hidden (Meth)acrylates

Contact Dermatitis, EarlyView.
We report three cases of allergic contact dermatitis (ACD) caused by acrylic resins used in creative hobbies, rather than by epoxy resins, despite these products being incorrectly labelled as “epoxy UV” resins. ABSTRACT Background Several cases of contact allergy to epoxy resins used in creative hobbies have been reported in recent years but not to ...

Structural characterization and optimum machining parameters of jute/carbon fibre hybrid reinforced epoxy composite laminates

Polymer International, Volume 75, Issue 9, Page 804-817, September 2026.
Hybrid jute/carbon epoxy laminates have better mechanical performance and less drilling damage by the use of optimized stacking sequence and machining parameters. Abstract Three composite laminate systems were produced using the standard hand lay‐up method: jute‐fibre‐reinforced polymer (JFRP), carbon‐fibre‐reinforced polymer (CFRP) and a hybrid of the

Synthesis of the Core Tetracycle of the Spirobiflavonoid Daphnodorin C

European Journal of Organic Chemistry, Volume 29, Issue 30, 12 August 2026.
Core spirotetracycle of daphnodorin C: Oxidative ring contraction of benzofuro[3,2‐b]chromenones affords novel 2,3′‐spirobi[benzofuran]diones, rather than the isomeric spiroketals. The first synthesis of the spirobi[benzofuran]dione core structure of the spirobiflavonoid daphnodorin C is described.

MiR‐940 Suppresses Ferroptosis by Controlling Expression of Key Regulatory Genes

Advanced Science, Volume 13, Issue 46, 17 August 2026.
A CRISPR‐based screening identified miR‐940 as a critical suppressor of ferroptosis in cancer. By coordinating the downregulation of pro‐ferroptotic genes with the upregulation of GPX4, miR‐940 establishes a regulatory network that protects against ferroptosis and correlates with poor clinical outcomes in distinct cancer entities.
