In Saccharomyces cerevisiae, the genes HXK2 and REG1 are believed to play a central role in carbon catabolite repression, acting on multiple pathways in the central metab. The present study aimed at quantifying the effect of deletion of genes HXK2 or REG1, ...
Despite striking advances in functional brain imaging, the cellular and molecular mechanisms that underlie the signals detected by these techniques are still largely unknown. The basic physiological principle of functional imaging is represented by the tig ...
The continuous delivery of glucose to the brain is critically important to the maintenance of normal metabolic function. However, elucidation of the hormonal regulation of in vivo cerebral glucose metabolism in humans has been limited by the lack of direct ...
Glucose is the major substrate that sustains normal brain function. When the brain glucose concentration approaches zero, glucose transport across the blood-brain barrier becomes rate limiting for metabolism during, for example, increased metabolic activit ...
The objective of this study was to characterize the dynamic adaptation of the oxidative capacity of Saccharomyces cerevisiae to an increase in the glucose supply rate and its implications for the control of a continuous culture designed to produce biomass ...
A tight coupling exists between neuronal activity and energy metabolism. Over a century ago Roy and Sherrington postulated that “the brain possesses intrinsic mechanisms by which its vascular supply can be varied locally in correspondence with local variat ...
Using optimized administration of 13C-labeled glucose, the time course of the specific activity of glucose was measured directly by in vivo 13C-NMR in the human brain at 4 Tesla. Subsequent label incorporation was measured at the C2, C3 and C4 positions of ...
Measurement of the resonances of glucose between 3.2 and 3.9 ppm in 1H NMR spectra from the human brain is difficult due to spectral overlap with peaks from more concentrated metabolites. The H1 resonance of α-D-glucose at 5.23 ppm is resolved from other m ...
Signals detected with functional brain imaging techniques are based on the coupling between neuronal activity and energy metabolism. Positron emission tomography signals detect blood flow, oxygen consumption and glucose utilization associated with neuronal ...
The difference between 1H nuclear magnetic resonance (NMR) spectra obtained from the human brain during euglycemia and during hyperglycemia is depicted as well-resolved glucose peaks. The time course of these brain glucose changes during a rapid increase i ...
