Zooplankton Epibionts in Boreal Lakes: Associations With DOC and Host Community Traits

Freshwater Biology, Volume 70, Issue 12, December 2025.
ABSTRACT Epibiosis in aquatic ecosystems is well‐documented, yet the factors influencing epibiont prevalence and host selection remain unclear. This study investigates how water quality parameters and zooplankton community dynamics influence epibiont prevalence, with a focus on ecological implications.

A digital shadow of CAR T cell expansion in a perfusion bioreactor: Informing optimal harvest times for autologous cell therapy

Biotechnology Progress, Volume 41, Issue 6, November/December 2025.
Using online metabolite data from the first few days of a bioreactor run, the digital shadow can forecast the cell concentration in real‐time with an accuracy of 13% (standard deviation ≈ 6%). These predictions can guide the optimal harvest time of CAR T cells for subsequent re‐infusion into the patient.

Induction of Bioactive Secondary Metabolites in Annona cherimola Mill. (Chirimoya) Seedlings Using Chitosan and Salicylic Acid as Elicitors

Plant-Environment Interactions, Volume 6, Issue 4, August 2025.
ABSTRACT The use of elicitors such as salicylic acid (SA) and chitosan (CH) represents an effective strategy to induce the production of secondary metabolites in plants. However, its application in seedlings of Annona cherimola Mill. has been scarcely explored.

The Phenolic Signature of Psidium cattleianum Fruits and Leaves Modulates TRPV1 and TRPA1 Transient Receptor Potential Channels: A Metabolomics, In Vitro, and In Silico Study

Food Science &Nutrition, Volume 13, Issue 4, April 2025.
An untargeted metabolomics study was performed to find the encompassed phytochemicals in the fruit and leaf extract of Psidium cattleianum. This enabled the annotation of 469 compounds belonging to different phenolic subclasses, with a predominance of flavonoids and phenolics.
