From the authors: “In conclusion, total renal blood flow and kidney function, as estimated from excretion of electrolytes and waste products, display profound circadian variations, whereas intrarenal oxygenation displays significantly less circadian variation.”

This study is highlighted as one of December’s “best of the best” as part of the American Physiological Society’s APSselect program.
