17‐epi‐Melianodiol, a new protolimonoid from Melia azedarach fruits, exhibits larvicidal activity and is associated with oxidative imbalance and midgut epithelial damage in Aedes aegypti larvae

Pest Management Science, Volume 82, Issue 9, Page 9240-9248, September 2026.
The bio‐guided phytochemical study resulted in the new compound 17‐epi‐melianodiol. The compound eliminated 100% of Aedes aegypti larvae at 100 ppm, causing pronounced morphological changes, cuticular damage, and extensive vacuolization. Abstract BACKGROUND In Brazil, Aedes aegypti is the primary vector of arboviruses such as dengue, chikungunya ...

Ameliorative Effects of Newly Developed Citrus Hybrid “Mubong” Peel Extract on Experimental Colitis and Gut Microbiota Dysbiosis

Food Science &Nutrition, Volume 14, Issue 7, July 2026.
DSS exposure induces severe colitis, causing gut dysbiosis and mucosal inflammation driven by NF‐κB activation and spikes in pathogenic bacteria, TNF‐α, and IL‐6. However, “Mubong” Peel Extract effectively disrupts this inflammatory cascade. By suppressing NF‐κB‐dependent transcriptional activity, the extract mitigates clinical symptoms like colon ...
