3. Mitochondrial Function represents the energy balance of the tissue Mitochondrial Function represents the energy balance of the tissue Tissue Energy Balance Mitochondrial NADH (Fluorometry) ATP Demand Typical Examples: Kidney Function Gastrointestinal Activity Muscle Contraction Brain Ionic Homeostasis Glandular Secretion Supply Tissue Blood Flow (LDF) HbO 2 Hemoglobin Oxygenation (Oximetry) Venule Arteriole O 2 O 2 O 2 O 2 2 O 2 O 2 O 2 O 2 O 2 O 2 O 2 O 2 O 2 O 2 O 2 O 2 O 2

7. Where to Monitor NADH redox state During the last 60 years NADH was monitored almost in all organs of the body. Our group (Mayevsky et al) had published more than 150 papers in various animal models. More than 1,000 papers had been published in this area of research.
