Insects With Survival Kits for Desiccation Tolerance Under Extreme Water Deficits.

abstract：:Background: Constant blood flow despite changes in blood pressure, a phenomenon called autoregulation, has been demonstrated for various organ systems. We hypothesized that by changing hydrostatic pressures in peripheral arteries, we can establish these limits of autoregulation in peripheral arteries based on local pu...
