Brain Energy Metabolism and Blood Flow Differences in Healthy Aging
Joel Aanerud,Per Borghammer,M. Mallar Chakravarty,Kim Vang,Anders Rodell,Kristjana Y. Jonsdottir,Arne Møller,Arne Møller,Mahmoud Ashkanian,Mahmoud Ashkanian,Manouchehr Seyedi Vafaee,Manouchehr Seyedi Vafaee,Peter Iversen,Peter Johannsen,Albert Gjedde +14 more
TL;DR: A possible mechanism of progression from healthy to unhealthy brain aging is established, as the regions most affected by age are the areas that are most vulnerable to neurodegeneration.

Effects of Cortisol on Carbohydrate, Lipid, and Protein Metabolism: Studies of Acute Cortisol Withdrawal in Adrenocortical Failure
Jens Juel Christiansen,C. B. Djurhuus,Claus Højbjerg Gravholt,Peter Iversen,Jens Sandahl Christiansen,Ole Schmitz,Jørgen Weeke,Jens Otto Lunde Jørgensen,Niels Møller +8 more
TL;DR: Cortisol withdrawal increased insulin sensitivity in terms of increased glucose oxidation and decreased endogenous glucose production; this may induce hypoglycemia in adrenocortical failure.
Normalization in PET group comparison studies--the importance of a valid reference region.
Per Borghammer,Kristjana Y. Jonsdottir,Paul Cumming,Karen Østergaard,Kim Vang,Mahmoud Ashkanian,Manouchehr Seyedi Vafaee,Peter Iversen,Albert Gjedde +8 more
TL;DR: In this article, the authors compared absolute CBF values, and CBF normalized to the gray matter (GM) and white matter (WM) means, and found that normalization to central WM yields less biased results in aging and hepatic encephalopathy (HE).

Peripheral benzodiazepine receptors in the brain of cirrhosis patients with manifest hepatic encephalopathy
Peter Iversen,Dorthe Aagaard Hansen,Dirk Bender,Anders Rodell,Ole Lajord Munk,Paul Cumming,Susanne Keiding +6 more
TL;DR: The hypothesis that ammonia-induced enhancement of peripheral benzodiazepine receptors in the brain is involved in the development of hepatic encephalopathy (HE) is tested by measuring the number of cerebral PBRs in specific brain regions in cirrhotic patients with an acute episode of clinically manifest HE and healthy subjects using dynamic 11C-PK11195 brain PET.

Decreased in vivo α2 adrenoceptor binding in the Flinders Sensitive Line rat model of depression.
Anne M. Landau,Anne M. Landau,Jenny Ann Phan,Jenny Ann Phan,Peter Iversen,Thea P. Lillethorup,Thea P. Lillethorup,Mette Kildevæld Simonsen,Gregers Wegener,Gregers Wegener,Steen Jakobsen,Doris J. Doudet,Doris J. Doudet +12 more
TL;DR: The results suggest that the behavioral deficits expressed in the FSL depression model are associated with functional over-activity of the NA system, leading to a greater understanding of the disease.
