Tunable biocomposite films fabricated using cellulose nanocrystals and additives for food packaging
Cellulose nanocrystals (CNCs) are considered a prospective packaging material to partially replace petroleumbased plastics attributed to their renewability, sustainability, biodegradability, and desirable attributes including transparency, oxygen, and oil ...
ELSEVIER SCI LTD2023Measuring Glycolytic Activity with Hyperpolarized [2H7, U-13C6] D-Glucose in the Naive Mouse Brain under Different Anesthetic Conditions
Rolf Gruetter, Bernard Lanz, Andrea Capozzi, Yves Pilloud, Emmanuelle Ines Flatt
Glucose is the primary fuel for the brain; its metabolism is linked with cerebral function. Different magnetic resonance spectroscopy (MRS) techniques are available to assess glucose metabolism, providing complementary information. Our first aim was to in ...
2021Very Selective Detection of Low Physiopathological Glucose Levels by Spontaneous Raman Spectroscopy with Univariate Data Analysis
Christian Enz, Sandro Carrara, Assim Boukhayma, Antonino Caizzone, Ata Jedari Golparvar
After decades of research on non-invasive glucose monitoring, invasive devices based on finger blood sampling are still the predominant reference for diabetic patients for accurately measuring blood glucose levels. Meanwhile, research continues improving p ...
2021Development and applications of hyperpolarized 13C and 1H MR spectroscopy of cerebral metabolism at ultra-high field
This thesis is composed of four studies centered on investigating cerebral metabolism using magnetic resonance spectroscopy (MRS) of hyperpolarized and non-hyperpolarized compounds at ultra-high field.
In the first two chapters, we studied longitudinally t ...
EPFL2021Sorbitol Demineralization by Ion Exchange
Edgard Gnansounou, Binod Parameswaran
Sorbitol is a sugar alcohol commonly known as D-glucitol. It is synthesized from glucose by a reduction reaction altering the aldehyde group to a hydroxyl group. The body slowly metabolizes sorbitol, minimizing the possibility of increasing the insulin lev ...
Springer Nature2019Ultra high magnetic field for glial contribution into brain metabolism studied by MR spectroscopy and CEST methods for molecular imaging of glycogen
Elise Marie Catherine Vinckenbosch
Magnetic resonance at ultra-high field increases signal and spectral dispersion. In this thesis, I use those characteristics to investigate three different subjects in 13C spectroscopy, hyperpolarized methods and chemical exchange saturation transfer (CEST ...
EPFL2018Modulation of the endogenous production of protoporphyrin IX in a yeast - based model organism
Georges Wagnières, Jaroslava Joniová, Emmanuel Louis Arthur Gerelli
The main aim of this study was to assess conditions at which simple yeast-based model organism produces maximal levels of protoporphyrin IX (PpIX) after an exogenous administration of its precursor, 5-aminolevulinic acid (ALA), and the ferrous-ion chelator ...
Spie-Int Soc Optical Engineering2017Measuring glucose cerebral metabolism in the healthy mouse using hyperpolarized C-13 magnetic resonance
Rolf Gruetter, Mor-Miri Mishkovsky, Arnaud Comment
The mammalian brain relies primarily on glucose as a fuel to meet its high metabolic demand. Among the various techniques used to study cerebral metabolism, C-13 magnetic resonance spectroscopy (MRS) allows following the fate of C-13-enriched substrates th ...
Springer Nature2017Proton diffusion spectroscopy and modeling of brain metabolism at 14.1T
As a field at the CIBM, Nuclear magnetic resonance (NMR)spectroscopy can be applied non-invasively to explore the metabolic fate of energy fuel substrates, as well as the rate at which they are consumed, using 13C and 1H nuclei. The work of this thesis enc ...
EPFL2016Conversion of chitin derived N-acetyl-D-glucosamine (NAG) into polyols over transition metal catalysts and hydrogen in water
Felix Daniel Bobbink, Ning Yan, Xi Chen
N-Acetyl-D-glucosamine (NAG), the monomer of the world's second most abundant biopolymer chitin, has been for the first time converted to its corresponding amide/amino substituted sugar alcohols, smaller C2-4 polyols and N-acetylmonoethanolamine (NMEA), ov ...
