Differential Effects of Cannabidiol and Cannabigerol on Cognition, Neuroinflammation, and Blood–Brain Barrier Integrity in a Rat Model of Iron Overload

Abstract Iron is an essential micronutrient for brain development, participating in mitochondrial respiration, myelination, and neurotransmitter synthesis. However, previous studies have demonstrated that excessive iron during early postnatal life induces oxidative reactions, lea...

Response of Tetranychus urticae (Acari: Tetranychidae) to natural products

Abstract The two-spotted spider mite, Tetranychus urticae (Acari: Tetranychidae), is a cosmopolitan pest of numerous crops, including grapevines, where outbreaks cause leaf chlorosis, necrosis, defoliation, and yield reduction. Intensive use of synthetic acaricides has led to res...
