Engineering New‐to‐Nature Biological Pathways for β,γ‐Alkanediol Synthesis

open access: yesAdvanced Science, Volume 13, Issue 23, 23 April 2026.
β,γ‐Alkanediols are value‐added chemicals to be used as functional solvents, biofuels, and cosmetic components. This work demonstrates a carboligation‐mediated approach for synthesis of linear chain β,γ‐alkanediols in Escherichia coli, namely, hexane‐2,3‐diol (2,3‐HDO) and pentane‐2,3‐diol (2,3‐PDO). The engineered E. coli cells produce 152.2 mm (17.98

Review: Inhibition of prolactin as a management tool in dairy husbandry

open access: yesAnimal, 2019
Accumulating evidence supports that the hormone prolactin (PRL) is galactopoietic in dairy ruminants. Accordingly, the inhibition of PRL secretion by the dopamine agonists quinagolide and cabergoline causes a sharp decline in milk production and could be
