Graph Chatbot
Chattez avec Graph Search
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.
For more than thirty years there has been a high demand for glucose measuring devices to replace the finger pricking methods and to improve the life quality of diabetics. Three approaches are possible, electrochemical, electromagnetic (including optical), ...
Crabtree neg. organisms such as Kluyveromyces, Pichia, Hansenula and Candida, are used to make selected org. products such as lactic acid. The organisms are cultured in a first culture medium that includes glucose, under conditions that promote cellular re ...
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 ...
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, ...
A novel approach for indirect biomass detn. in case of non-const. specific metabolic rates is reported. Specific glucose consumption rate was detd. during a first calibration culture for both free suspended and immobilized cells. It was expressed as a line ...
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 ...
The estn. of the intracellular fluxes of mammalian cells using only the mass balances of the relevant metabolites is not possible because the set of linear equations defined by these mass balances is undetd. Either addnl. exptl. flux data or addnl. theor. ...
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 miniaturised Total chemical Analysis System (μTAS) for glucose and lactate measurement in biological samples constructed based on an integrated microdialysis sampling and detection system. The complete system incorporates a microdialysis probe for intrav ...
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 ...
