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.
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 ...
The influence of substrate compn. on the yield, nature, and compn. of exopolysaccharides (EPS) produced by the food-grade strain G. xylinus I-2281 was investigated during controlled cultivations on mixed substrates contg. acetate and either glucose, sucros ...
TThe synthesis and properties of a novel set of building blocks for the preparation of self-assembling biomaterials are described. These molecules consist of a relatively short oligo(L-lactic acid)n segment (n̄ = 10-40) that is substituted with a cholester ...
This report describes the synthesis and supramolecular organization of a novel class of linear-dendritic block copolymers. The molecules, which are termed rodcoil dendrons, consist of a cholesterol moiety that is attached to L-lysine dendrons of three diff ...
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 ...
The formation of 4-hydroxy-2,5-dimethyl-3(2H)-furanone (HDMF) and 2(or 5)-ethyl-4-hydroxy-5(or 2)-methyl-3(2H)-furanone (EHMF) from pentose sugars was studied in Maillard model systems. The amts. generated at 90 DegC for 1 h were detd. by isotope diln. ass ...
PURPOSE: To investigate the potential use of polymeric nanoparticles for the delivery of antisense oligonucleotides in HIV-1-infected cell cultures. METHODS: Phosphorothioate oligonucleotides were encapsulated into poly (D,L-lactic acid) nanoparticles. Two ...
Formation of racemic pentose-2,4-bisphosphates is demonstrated, starting from glycolaldehyde phosphate and glyceraldehyde-2-phosphate, and induced by mixed valence double layer metal hydroxide minerals. The reactions proceed from dil. aq. reactant solns. ( ...
A new class of molecules for the preparation of self-assembling biomaterials were synthesized. These molecules consist of a cholesteryl-moiety attached via an oligo(ethylene oxide) or oligo(L-lactic acid) segment to a biologically relevant headgroup. The o ...
Astrocytes appear to be ideally localized to couple neuronal activity to energy metabolism. First, specialized processes, the astrocytic end-feet surround blood vessels, the source of glucose for the brain. Second, other processes ensheath synapses and exp ...
