Defusing redox bombs?
Proteins catalyze crucial reactions via unstable, high-energy chemical intermediates. In the absence of physiological substrates, activated redox cofactors become ticking time bombs, capable of producing oxidative damage to the protein. In PNAS, Gray and Winkler (1) propose that chains of tryptophan (Trp) and tyrosine (Tyr) residues may serve as escape routes for potentially damaging, highly ox...

متن کاملSticky Demand vs. Sticky Prices
Sticky demand – sticky nominal spending – acts as a substitute for sticky prices. In an inventorytheoretic model of the demand for money, monetary injections are offset by endogenous movements in velocity that keep nominal spending flat. When embedded in a sticky price model, this reduces the model’s reliance on implausibly large amounts of exogenous stickiness. For example: 6 months asset mark...
