Pulsed Electric Field‐Assisted Recovery of Phenolic Compounds From Haskap (Lonicera caerulea L.) Pomace: Influence of Processing Parameters and Cell Disintegration

Journal of Food Science, Volume 91, Issue 7, July 2026.
ABSTRACT This study investigated the effect of pulsed electric field (PEF) treatment on cell disintegration and phenolic extractability from haskap (Lonicera caerulea L.) pomace generated after juice processing. Pomace samples were subjected to 16 PEF conditions combining electric field strengths of 1.0 and 1.5 kV/cm, pulse frequencies of 5 and 10 Hz ...

Forage Plant Host and Early Feeding Choices Affect Spodoptera litura Feeding, Development and Egg‐Laying

Entomologia Experimentalis et Applicata, Volume 174, Issue 7, Page 670-684, July 2026.
We assessed Spodoptera litura (Lepidoptera: Noctuidae) performance on five common pasture plant species. Larvae consumed more dock, plantain and chicory per day than red or white clover, but with lower conversion efficiencies. Feeding on red clover reduced weights and egg laying, and lengthened development times compared with plantain.

Yougui Pills Alleviate Osteoporosis by Inhibiting Mesenchymal Stem Cell ROS Accumulation via the Nrf2/HO‐1 Pathway

Journal of Cellular and Molecular Medicine, Volume 30, Issue 14, July 2026.
ABSTRACT Osteoporosis (OP) is a prevalent skeletal disorder characterized by progressive bone mass loss and deteriorated microarchitecture, in which oxidative stress‐induced mesenchymal stem cell (MSC) dysfunction serves as a core pathogenic mechanism. Yougui Pills (YGPs), a classical traditional Chinese medicine formula, are widely applied in clinical

Studies on iridoid-related compounds. IV Antitumor activity of iridoid aglycones.

Chemical and Pharmaceutical Bulletin, 1986
An extensive study has been made on the antitumor activity of several iridoid glycosides and their aglycones in mice bearing the experimental tumor leukemia P388. Most of the aglycones were found to be active. Among them, scadoside methyl ester aglycone (SMEH) showed the most potent activity, and it was furhter tested against several kinds of ...
