3D Bioprinting of Thick Adipose Tissues with Integrated Vascular Hierarchies

open access: yesAdvanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
An advanced 3D bioprinting technique is used here to create thick adipose tissues with a central, vessel and extensive branching. The construct is made using alginate, gelatin and collagen‐based bioinks. Flow through the complex vessel network is demonstrated as well as its successful integration with a femoral artery following implantation in a rat ...

Exchange Rate Behavior and Exchange Rate Puzzles: Why the XVIII Century Might Help [PDF]

open access: yes
This article explores the behavior of exchange rates in Spain during the XVIII century. We posit that exchange rates were the result of both government intervention over nominal values of currencies and the estimate that the market –of bills of exchange-
