Ingestion of attractive toxic sugar baits containing ivermectin before and after blood feeding affects the biology and reproduction of Aedes aegypti (Diptera: Culicidae)

open access: yesMedical and Veterinary Entomology, EarlyView.
Attractive toxic sugar bait containing ivermectin (ATSB‐IVM) ingestion markedly reduced blood feeding, survival, oviposition, egg production and larval hatching, with the strongest effects when baits were ingested before blood feeding. Timing of ingestion (48–96 h before or after blood feeding) shaped sublethal impacts across the first and second ...

Neuronutraceuticals for Alzheimer's Disease Treatment: A Systematic Review of Randomised Controlled Trials Over the Last 20 Years

open access: yesPhytochemicals in Food and Medicine, Volume 1, Issue 1, March 2026.
This PROSPERO‐registered review analysed 37 RCTs on neuronutraceuticals for Alzheimer's disease. Despite diverse targets—amyloid/tau, inflammation, oxidative stress, metabolism, synaptic plasticity, cholinergic and hormonal—the evidence was of low quality. RoB2 flagged attrition (86.5%) and reporting bias (81%). Current data do not support clinical use;

Inversion of the anomeric configuration of the transferred sugar during inactivation of the macrolide antibiotic oleandomycin catalyzed by a macrolide glycosyltransferase [PDF]

open access: yes, 1934
Macrolides are a group of antibiotics structurally characterized by a macrocyclic lactone to which one or several deoxy-sugar moieties are attached. The sugar moieties are transferred to the different aglycones by glycosyltransferases (GTF). The OleI GTF
