Adenosine has been proposed as a key factor regulating the metabolic balance between energy supply and demand in the central nervous system. Because astrocytes represent an important cellular element in the control of brain energy metabolism, we investigat ...
Body mass and composition reflect the combined effects of three processes: energy intake, energy partitioning (storage), and energy expenditure. Energy is released from food as it is combusted to carbon dioxide and water, and is expended as heat and work w ...
The neuropathological and clinical symptoms of Huntington's disease (HD) can be simulated in animal model with systemic administration of 3-nitropropionic acid (3-NP). Energy defects in HD could be ameliorated by administration of coenzyme Q10 (CoQ10), cre ...
This paper describes an improvement of a method for continuous calibration of the global heat transfer coeff., recently described in literature [A. Tietze, Moglichkeiten und Grenzen der Temperaturschwingungskalorimetrie, Doctoral Thesis, Technishe Universi ...
OBJECTIVE: To investigate whether acute feeding induces changes in circulating leptin levels in humans and whether these changes vary according to nycthemeral cycle. METHODS: First experiment. Eighteen male subjects were given a fatty meal at 08.00 h. Bloo ...
Evidence suggests that astrocytes might play an important role in cerebral energy metabolism. A recently developed cell line, called DI TNC1, displays several characteristic features of astrocytes. Thus, we have investigated in these cells a number of para ...
Localized (13)C NMR spectroscopy provides a new investigative tool for studying cerebral metabolism. The application of (13)C NMR spectroscopy to living intact humans and animals presents the investigator with a number of unique challenges. This review pro ...
Obesity is a disorder of energy balance, indicating a chronic disequilibrium between energy intake and expenditure. Recently, the mouse ob gene, and subsequently its human and rat homologues, have been cloned. The ob gene product, leptin, is expressed excl ...
The influence of development and ethinylestradiol (EE) on apolipoprotein (apo) A-I, A-II, and E mRNA in rat liver and intestine was studied by dot blot hybridization and Northern blot analysis. ApoA-I mRNA levels were maximal in the perinatal period and de ...
A critical issue in brain energy metabolism is whether lactate produced within the brain by astrocytes is taken up and metabolized by neurons upon activation. Although there is ample evidence that neurons can efficiently use lactate as an energy substrate, ...
