Food Safety and Health, EarlyView.This review elucidates the formation pathways and detection technologies for ethyl carbamate, biogenic amines, and higher alcohols in Huangjiu. It concludes that integrated control frameworks are essential to decouple safety risks from the metabolic processes responsible for flavor development.

Dasatinib and quercetin prevent alveolar bone loss in aged mice
Journal of Periodontology, EarlyView.Abstract Background Recent findings have associated alveolar bone loss (ABL) with the presence of senescent cells. Aging and the accumulation of senescent cells are associated with a pro‐inflammatory environment which may exacerbate tissue damage.

Limnology and Oceanography: Methods, EarlyView.Abstract Assigning taxonomic identity and thus assessing taxonomic diversity in gelatinous zooplankton is challenging due to their fragility and difficult preservation. Formalin fixation compromises DNA integrity, while flash‐freezing, ethanol, and acetone preservation affect morphological features. In this study, we developed a methodological protocol

Mass Spectrometry Insights Into Post‐Translational Modifications in Extracellular Vesicles
Mass Spectrometry Reviews, EarlyView.ABSTRACT Extracellular vesicles (EVs) are membrane‐enclosed structures secreted by virtually all living cells, serving as essential mediators of intercellular communication in both physiological and pathological processes. There is growing interest in their potential applications as biomarkers, therapeutic targets, and drug delivery systems, which ...

Plasmepsins as Antimalarial Drug Targets—Then, Now, and the Future
Medicinal Research Reviews, EarlyView.ABSTRACT Malaria is a devastating disease caused by Plasmodium parasites. Plasmodium parasites express ten cathepsin D‐like aspartyl proteases, called plasmepsins (PMs). These PMs have diverse roles fulfill diverse functions throughout the parasite's lifecycle, though several exhibit functional redundancies. Among them, PMV, PMIV, and PMX are essential
