... marmoratus appears to be oxygen availability, as aquatic hyperoxia and air exposure both result in hypertrophy of oxidative muscle fibers. Oxidative muscle Hyperoxia Slow myosin Alkaline phosphatase Succinate dehydrogenase Kryptolebias marmoratus The physical disparities between air...

...). The Glanville fritillary butterfly ( Melitaea cinxia ) possesses a balanced polymorphism in Sdhd , shown previously to affect HIF pathway activation and tracheal morphology and used here to experimentally test the hypothesis that variation in succinate dehydrogenase affects oxidative injury . We stimulated...

... supplied (capillary domain). We demonstrate that local M O 2 ,max assessed by succinate dehydrogenase histochemistry: (1) varied more than 100-fold between individual capillaries and (2) was positively correlated to capillary domain area in both human vastus lateralis ( R =0.750, P <0.001) and soleus...

.... The present study confirmed that succinate oxidation is reduced during torpor in liver and skeletal muscle at 37 and 10°C over a 100-fold range of succinate concentrations. At 37°C, this suppression resulted from inhibition of succinate dehydrogenase (SDH), which had a greater affinity for oxaloacetate...

... of the same myosin immunohistochemical type. Myofibrillar adenosine triphosphatase, succinate dehydrogenase andα-glycerophosphate dehydrogenase activities were determined for a sample of motor unit and non-motor unit fibers, providing a measure of three enzyme activities often used to characterize fiber...
