...Hassan M. Yaish; Roberto H. Nussenzveig; Archana M. Agarwal; Abdul H. Siddiqui; Robert D. Christensen We report a neonate with early and severe hemolytic jaundice and low erythrocyte pyruvate kinase enzymatic activity (<2 U/g hemoglobin, reference interval 9-22). We found her asymptomatic mother...

..., phosphofructokinase 1 and pyruvate kinase, were lower in fetal than in pediatric and adult samples. For both of these enzymes, there was a significant reduction in activity of livers from fetuses of 34–37 weeks’ gestation. Both enzymes showed hyperbolic kinetics at 24 weeks’ gestation, but this changed to sigmoid...

...J. Frohlich; P. Hahn; L. Kirby; W. Webber Interscapular brown adipose tissue (BAT) from fetal rats was maintained in Eagle’s minimal essential medium for 6–24 h at 37 or 25 °C. Pyruvate kinase (PK), cytoplasmic and mitochondrial α-glycerophosphate dehydrogenase and phosphoenolpyruvate carboxykinase...

...H. Willgerodt; K. Vízek; M. Rážová; V. Melichar The activity of glucose-6-phosphate dehydrogenase, phosphogluconate dehydrogenase, pyruvate kinase (PK) and lactate dehydrogenase (LDH) was measured in human adipose tissue (AT) of newborns aged 0–2 and 2–48 h, of 3- to 5-month-old infants...
