- Cerebral desaturation during exercise reversed by O2 supplementationH B Nielsen
Copenhagen Muscle Research Center, Department of Anesthesia, Rigshospitalet, University of Copenhagen, 2100 Copenhagen O, Denmark
Am J Physiol 277:H1045-52. 1999..05). These results indicate that an elevated inspiratory O2 fraction increases exercise performance related to maintained cerebral oxygenation rather than to an effect on the working muscles...
- Arterial desaturation during exercise in man: implication for O2 uptake and work capacityHenning Bay Nielsen
The Copenhagen Muscle Research Centre Department of Anaesthesia, Rigshospitalet, University of Copenhagen, Copenhagen, Denmark
Scand J Med Sci Sports 13:339-58. 2003..It is proposed that other organs benefit from enhanced O2 availability, and especially the brain appears to increase its oxygenation during maximal exercise with hyperoxia...

Department of Anaesthesia, The Copenhagen Muscle Research Centre, Rigshospitalet, University of Copenhagen, Copenhagen, Denmark
Sports Med 33:853-67. 2003..A physiological perspective is of importance for evaluation of the exercise-induced change in lymphocyte function and, in turn, to post-exercise increased susceptibility to infections...
- Cerebral oxygenation determined by near-infrared spectrophotometry in patients with fulminant hepatic failureHenning Bay Nielsen
Department of Hepatology, Rigshospitalet, University of Copenhagen, Blegdamsvej 9, 2100, København Ø, Denmark
J Hepatol 38:188-92. 2003..The aim of this study was to determine if near-infrared spectrophotometry (NIRS) could detect a raise in cerebral blood flow and oxygenation induced by noradrenaline (NA) infusion...
- Bicarbonate attenuates arterial desaturation during maximal exercise in humansHenning B Nielsen
The Copenhagen Muscle Research Center, Department of Anesthesia, Rigshospitalet, DK 2100 Copenhagen, Denmark
J Appl Physiol 93:724-31. 2002..The enlarged blood-buffering capacity after infusion of Bic attenuated acidosis and in turn arterial desaturation during maximal exercise...
- Bicarbonate attenuates intracellular acidosisH B Nielsen
Copenhagen Muscle Research Center, Department of Anaesthesia, Rigshospitalet, University of Copenhagen, Denmark

- Cardiac arrest during exercise: anomalous left coronary artery from the pulmonary trunkH B Nielsen
Department of Cardiology, Rigshospitalet, University of Copenhagen, Denmark
Scand Cardiovasc J 33:369-71. 1999..A successful surgical correction of the anomalous coronary artery was performed in two of the patients...
- N-acetylcysteine attenuates oxidative burst by neutrophils in response to ergometer rowing with no effect on pulmonary gas exchangeH B Nielsen
Department of Anaesthesia, Rigshospitalet, University of Copenhagen, Denmark
Int J Sports Med 22:256-60. 2001..We conclude that the neutrophil oxidative burst to exercise does not influence pulmonary gas exchange during and after maximal rowing...
- Attenuated hepatosplanchnic uptake of lactate during intense exercise in humansH B Nielsen
Department of Anesthesia, Rigshospitalet, University of Copenhagen, 2100 Copenhagen, Denmark
J Appl Physiol 92:1677-83. 2002..However, it appeared that the contribution of the Cori cycle decreased, and the accumulation of lactate in blood became influenced by the reduced hepatosplanchnic blood flow...
- Exercise induces hepatosplanchnic release of heat shock protein 72 in humansMark A Febbraio
Copenhagen Muscle Research Centre, University of Copenhagen, Denmark
J Physiol 544:957-62. 2002..2 +/- 0.2 pg min(-1) after 120 min. These data demonstrate that the splanchnic tissues release HSP72 during exercise and this release is responsible, in part, for the elevated systemic concentration of this protein during exercise...
- The effect of fractionated plasma separation and adsorption on cerebral amino acid metabolism and oxidative metabolism during acute liver failurePeter Nissen Bjerring
Department of Hepatology, Rigshospitalet, Copenhagen, Denmark
J Hepatol 57:774-9. 2012..This study aimed at assessing the effect of fractionated plasma separation and adsorption (FPSA), an extracorporeal liver support system, on cerebral amino acids and lactate to pyruvate ratio...

Copenhagen Wound Healing Center, the Department of Surgical Gastroenterology, Bispebjerg Hospital, University of Copenhagen, DK 2400 Copenhagen, Denmark
Surgery 136:1047-53. 2004..Smoking is associated with surgical wound infections, impaired wound healing, and tissue-destructive disorders. The mechanisms are largely unknown, but changes in the function and activity of inflammatory cells may be involved...
- Cerebral oxygenation during exercise in patients with terminal lung diseaseGabrielle Jensen
Department of Anesthesia, Copenhagen Muscle Research Center, Copenhagen, Denmark
Chest 122:445-50. 2002..In patients with terminal lung disease who were exercising, we assessed whether improved arterial O2 saturation with an increased fraction of inspired oxygen (FIO2) affects cerebral oxygenation...
- Hepatosplanchnic clearance of interleukin-6 in humans during exerciseMark A Febbraio
Skeletal Muscle Research Laboratory, School of Medical Sciences, RMIT Univ, Bundoora, Victoria 3083, Australia
Am J Physiol Endocrinol Metab 285:E397-402. 2003..05). These data demonstrate that the hepatosplanchnic viscera remove IL-6 from the circulation in humans. This removal may constitute a mechanism limiting the negative chronic metabolic action of chronically elevated circulating IL-6...
