Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.
AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
A tight coupling exists between synaptic activity and glucose utilization by astrocytes. Metabolic cooperation between neurons and astrocytes mediates this coupling. During synaptic activation, glutamate that is released in the synaptic cleft as a neurotra ...
The understanding of dynamic metabolic regulations is important for physiol. studies and strain characterization tasks. The present study combined transient expts. with online metabolic flux anal. (MFA) in order to quantify metabolic regulations, namely ca ...
To study intramitochondrial phospholipid flow, radiolabeled phosphatidylserine was introduced into isolated rat liver mitochondria from donor vesicles through the action of a nonspecific lipid transfer protein. Imported phosphatidylserine was rapidly decar ...

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 ...
Glucose-evoked mitochondrial signals augment ATP synthesis in the pancreatic β cell. This activation of energy metabolism increases the cytosolic ATP/ADP ratio, which stimulates plasma membrane electrical activity and insulin granule exocytosis. We have re ...
Thermodynamic feasibility analysis (TFA) has been used as a toot capable of providing additional constraints to the mass balance-based methods of analysis of Metabolic networks (e.g., flux balance analysis). Several publications have recently appeared in w ...
Diminished mitochondrial oxidative phosphorylation and aerobic capacity are associated with reduced longevity. We tested whether resveratrol (RSV), which is known to extend lifespan, impacts mitochondrial function and metabolic homeostasis. Treatment of mi ...
We studied the effects of chloramphenicol on brain glucose utilization and sleep-wake cycles in rat. After slightly anaesthetized animals were injected with [18F]fluoro-2-deoxy-D-glucose, we acquired time-concentration curves from three radiosensitive beta ...
The growth physiol. of S. cerevisiae strains H1022 and Whi2+ was studied in aerobic batch and continuous (chemostat) cultures. Results from the measurement of biomass and medium components (off-line) together with O2, CO2, and heat measurements (online) we ...
