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 ...
To date, functional 1H NMR spectroscopy has been utilized to report the time courses of few metabolites, primarily lactate. Benefiting from the sensitivity offered by ultra-high magnetic field (7 T), the concentrations of 17 metabolites were measured in th ...
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 ...
BACKGROUND: For a long time now, glucose has been thought to be the main, if not the sole substrate for brain energy metabolism. Recent data nevertheless suggest that other molecules, such as monocarboxylates (lactate and pyruvate mainly) could be suitable ...
An in vitro model, designated the Simulator of the Human Intestinal Microbial Ecosystem (SHIME), was used to study the effect of a soygerm powder rich in beta-glycosidic phytoestrogenic isoflavones on the fermentation pattern of the colon microbiota and to ...
The objective of this thesis was to evaluate the feasibility for the production of fuel bioethanol from whey permeate. The identification of the limiting factors of the process revealed that the stabilization of the substrate was critical to the use of whe ...
Lactate concentration in physiological fluids is an indicator of the energy production under anaerobic conditions of the whole organism [1]. Normal value for lactate level in blood ranges from 0.5 – 2.5 mM. Blood lactate values exceeding 7-8 mM are sometim ...
The objective of this thesis was to characterize the growth stoichiometry, the specific recombinant protein productivity and the regulation of the alcohol oxidase (AOX) enzyme of a Pichia pastoris Mut+ strain, performing conventional chemostat cultures and ...
This paper reports the photocatalytic disinfection of water contaminated by a mixture of Escherichia coli and Bacillus sp. as well as that of wastewater containing a larger microbial community. The photocatalytic reactions were carried out in a coaxial pho ...
Under particular circumstances like lactation and fasting, the blood-borne monocarboxylates acetoacetate, beta-hydroxybutyrate, and lactate represent significant energy substrates for the brain. Their utilization is dependent on a transport system present ...
