Metabolic signatures of triatomine vectors of Trypanosoma cruzi unveiled by metabolomics. [PDF]

PLoS ONE, 2013
Chagas disease is a trypanosomiasis whose causative agent is the protozoan parasite Trypanosoma cruzi, which is transmitted to humans by hematophagous insects known as triatomines and affects a large proportion of South America.

Effects of catechins, resveratrol, silymarin components and some of their conjugates on xanthine oxidase‐catalyzed xanthine and 6‐mercaptopurine oxidation

Journal of the Science of Food and Agriculture, Volume 105, Issue 5, Page 2765-2776, 30 March 2025.
Abstract BACKGROUND Over the past two decades, the global incidence of gout has markedly increased, affecting people worldwide. Considering the side effects of xanthine oxidase (XO) inhibitor drugs (e.g. allopurinol and febuxostat) used in the treatment of hyperuricemia and gout, the potential application of phytochemicals has been widely studied.

Pyruvate Kinase M2 Mediates Apigenin‐Induced Energy Crisis and Apoptosis in Colon Cancer Cells

Food Frontiers, Volume 7, Issue 4, July 2026.
Apigenin, a dietary flavonoid with low toxicity, induces profound bioenergetic collapse in colon cancer cells by downregulating PKM2. This metabolic crisis, characterized by suppressed glycolysis and mitochondrial dysfunction, ultimately triggers robust apoptosis.

Discovery of pseudobaptigenin synthase in fungal‐infected Trifolium pratense roots

The Plant Journal, Volume 127, Issue 1, July 2026.
Significance Statement The discovery of pseudobaptigenin synthase in red clover (CYP76F319), catalyzing the formation of a methylenedioxy bridge to convert calycosin to pseudobaptigenin. The integration of metabolomic and transcriptomic datasets to describe the defense response in red clover roots to hemibiotrophic and necrotrophic fungi.

Electronic Smoking Devices Among University Students: Usage Patterns and Chemical Composition of Inhaled Substances

Analytical Science Advances, Volume 7, Issue 1, June 2026.
ABSTRACT This study investigated the prevalence of electronic smoking device (ESD) use and its associated behavioural and chemical risks among university students in Bahia, Brazil. A cross‐sectional survey was conducted with 355 students from public and private institutions through an online questionnaire between April and May 2023. Among participants,

Formation and Characterization of Insoluble Anthocyanins‐λ‐carrageenan Biopolyelectrolyte Complexes: Structural Morphology, Thermal Stability, and Release Dynamics

ChemFoodChem, Volume 2, Issue 2, June 2026.
Insoluble biopolyelectrolyte complexes formed between blackberry anthocyanins and λ‐carrageenan are investigated. Optimal complexation occurs at low carrageenan ratios and acidic pH, producing porous hydrogel‐like structures with enhanced thermal stability.
