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 ...
Oxidn.-sensitive nanoparticles have been decorated with an oxidizing enzyme (glucose oxidase) for release behavior that is responsive to the presence of the enzyme substrate (glucose). [on SciFinder (R)] ...
Objective - Sirtuin 1 (SIRT1) is implicated in the regulation of mitochondrial function, energy metabolism, and insulin sensitivity in rodents. No studies are available in humans to demonstrate that SIRT1 expression in insulin sensitive tissues is associat ...
Barbiturates are regularly used as an anesthetic for animal experimentation and clinical procedures and are frequently provided with solubilizing compounds, such as ethanol and propylene glycol, which have been reported to affect brain function and, in the ...
Obesity and dyslipidemia are often found in association with insulin resistance (IR). These components combined with hypertension characterize the most common endocrine disorder in humans, the metabolic syndrome. Thus, in addition to profiling body weight ...
OBJECTIVE: To investigate the impact of visceral obesity on cholesterol metabolism in normoglycemic offspring of patients with type 2 diabetes. RESEARCH METHODS AND PROCEDURES: The proportion of intra-abdominal fat (IAF) was measured by abdominal computer ...
The brain contains a significant amount of glycogen that is an order of magnitude smaller than that in muscle, but several-fold higher than the cerebral glucose content. Although the precise role of brain glycogen to date is unknown, it seems affected by f ...
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 ...
Specialized glucosensing neurons are present in the hypothalamus, some of which neighbor the median eminence, where the blood–brain barrier has been reported leaky. A leaky blood–brain barrier implies high tissue glucose levels and obviates a role for endo ...
The rate of (13)C-label incorporation into both aspartyl (NAA C3) and acetyl (NAA C6) groups of N-acetyl aspartate (NAA) was simultaneously measured in the rat brain in vivo for up to 19 h of [1-(13)C]glucose infusion (n = 8). Label incorporation was detec ...
