Simulated microgravity exposure markedly attenuates the baroreflex total loop gain and induces orthostatic hypotension in male rats

Physiological Reports
Autonomic dysfunction is recognized as the central mechanism of orthostatic hypotension after microgravity exposure. Because the arterial baroreflex regulates arterial pressure (AP) via sympathetic nerve activity (SNA), we investigated the systematic ...

3D‐Nanoprinted Fluidically Steerable Soft Robotic Microcatheters

Advanced Robotics Research, EarlyView.
This work introduces a ∼3‐French (1 mm‐in‐diameter) soft robotic microcatheter fabricated by means of two‐photon direct laser writing. The 3D‐printed microcatheter enables remote, on‐demand steering via microfluidic actuation for guidewire‐free navigation of vascular networks as well as microcatheter‐mediated delivery of fluidic payloads to target ...
