Autor: Janny Takens, A.M. Gerding, W. G. Zijlstra, Jaap R. G. Kuipers, Marieke C. Molenkamp, Gertie C. M. Beaufort-Krol

Publikováno v: Metabolism, 50(4), 399-406. W B SAUNDERS CO-ELSEVIER INC

In a previous study we found, after an overnight fast of 18 hours, a lower arterial glucose concentration and a depressed glycogenolysis in lambs with aortopulmonary left-to-right shunts. During exercise, glucose and free fatty acids (FFA) concentrat

Autor: Hennie Knoester, W. G. Zijlstra, Jaap R. G. Kuipers, Beatrijs Bartelds, Janny Takens, Gioia B. Smid, Gertie C. M. Beaufort-Krol, Hugo S. A. Heymans

Publikováno v: Circulation, 99(14), 1892-1897. LIPPINCOTT WILLIAMS & WILKINS

Background —Around birth, myocardial substrate supply changes from carbohydrates before birth to primarily fatty acids after birth. Parallel to these changes, the myocardium is expected to switch from the use of primarily lactate before birth to fa

Lyophilized bovine hemoglobin as a possible reference material for the determination of hemoglobin derivatives in human blood

Autor: W. G. Zijlstra, Bart Maas, Rob Ernst, Anton H. J. Maas, Anneke Buursma

Publikováno v: Clinical Chemistry. 44:2331-2339

We investigated the suitability of a lyophilized bovine hemoglobin (LBH) preparation containing various fractions of oxyhemoglobin (O2Hb), carboxyhemoglobin (COHb), and methemoglobin (MetHb) for quality assessment in multicomponent analysis (MCA) of

Spectrophotometry of Hemoglobin: Absorption Spectra of Bovine Oxyhemoglobin, Deoxyhemoglobin, Carboxyhemoglobin, and Methemoglobin

Autor: W G Zijlstra, A Buursma

Publikováno v: Comparative biochemistry and physiology b-Biochemistry & molecular biology, 118(4), 743-749. ELSEVIER SCIENCE INC

The absorptivity at 540 nm of bovine hemiglobincyanide (cyanmethemoglobin) was determined on the basis of the iron content and found to be equal to the established value for human hemiglobincyanide (11.0 L . mmol(-1).cm(-1)). On this basis the absorp

Physical adaptation of children to life at high altitude

Autor: K. de Meer, W. G. Zijlstra, H. S. A. Heymans

Publikováno v: European Journal of Pediatrics. 154:263-272

Children permanently exposed to hypoxia at altitudes of > 3000 m above sea level show a phenotypical form of adaptation. Under these environmental conditions, oxygen uptake in the lungs is enhanced by increases in ventilation, lung compliance, and pu
