The effect of putrescine on space use and activity in sea lamprey (Petromyzon marinus)
Scientific Reports, 2022 Fish use odor to avoid exposure to predation and disease. Harnessing these odors as repellents is proving useful for management initiatives that conserve native species or control invasive populations.

Potential of Seaweed to Improve the Quality and Shelf Life of Fish and Fishery Products
Food Safety and Health, EarlyView.Growing global demand for safe fish preservation has increased interest in natural alternatives. Seaweed‐derived bioactive compounds possess antioxidant and antimicrobial properties that enhance fish quality, safety, and shelf life. These sustainable preservatives may reduce spoilage and synthetic preservative use, though further research ...

Regulation of Macromolecular Synthesis by Putrescine in a Conditional Escherichia coli Putrescine Auxotroph [PDF]
Journal of Bacteriology, 1972 Addition of putrescine to a slowly growing, polyamine-starved Escherichia coli K-12 mutant conditionally incapable of synthesizing putrescine causes the immediate stimulation of protein synthesis. After a period ranging from 60 to 105 min, ribonucleic acid (RNA) and deoxyribonucleic acid (DNA) syntheses are also ...

International Journal of Cancer, EarlyView.ABSTRACT In Lynch syndrome, colonoscopy surveillance for colorectal cancer (CRC) is burdensome and post‐colonoscopy CRCs still occur. Unlike the faecal immunochemical test (FIT), gut metabolomic alterations including amino‐acids have shown potential as non‐invasive biomarkers for detecting both advanced and non‐advanced sporadic colorectal neoplasia ...

Proteo‐transcriptomic insights into the venom composition of the ectoparasitoid Eupelmus urozonus
Pest Management Science, EarlyView.Integrated venom‐gland transcriptomics and venom proteomics of Eupelmus urozonus identified 316 venom proteins, including 75 secreted candidates, revealing diverse hydrolases, proteases/inhibitors and many uncharacterized effectors. Abstract BACKGROUND Ectoparasitoid venoms are ‘cocktails’ of bioactive molecules injected during oviposition to paralyze ...

The importance of putrescine in the human body
Postępy Higieny i Medycyny Doświadczalnej, 2014 Putrescine plays a very important role in the regulation of division, differentiation and maturation of cells as well as apoptosis. As the polycationic molecule it stabilizes the structure of DNA and participates in the functioning of cell membranes. It is able to interact with series of ion channels and has affinity for many receptors.

Revisiting small‐molecule fluorescent probes in food freshness detection
Smart Molecules, EarlyView.Fluorescent probes serve as versatile tools for food freshness monitoring. This review summarizes recent advances in probes targeting biogenic amines, hydrogen sulfide, pH values, and other key spoilage markers, highlighting their design principles, sensing mechanisms, and practical applications in food quality monitoring. Abstract Food spoilage driven

Environmental Toxicology, EarlyView.ABSTRACT Organophosphate esters (OPEs) are found ubiquitously in the environment and exposure to these chemicals has induced behavioral, developmental, and morphological impairments in several model organisms. Yet there is still a lack of understanding of how sub‐lethal exposure disrupts organism function at the molecular‐level, especially for Daphnia ...
