Risk factors for systemic inflammatory response syndrome after endoscopic lithotripsy for upper urinary calculi.

Background: To explore the risk factors for systemic inflammatory response syndrome (SIRS) after endoscopic lithotripsy for upper urinary calculi.

Methods: This retrospective study included patients with upper urinary calculi who underwent endoscopic lithotripsy in the First Affiliated Hospital of Zhejiang University between June 2018 and May 2020.

Results: A total of 724 patients with upper urinary calculi were included.

Rodent retinal microcirculation and visual electrophysiology following simulated microgravity.

How the absence of gravity affects the physiology of human beings is generating global research interest as space exploration, including missions aboard the International Space Station, continues to push boundaries. Here, we examined changes in retinal microcirculation and visual electrophysiology in mice suspended by their tails to simulate the cephalad movement of blood that occurs under microgravity conditions. Tail suspension was performed with a head-down tilt with a recommended angle of 30°.
