Enabling Stroke Theranostics with Hyperpolarized Magnetic Resonance
The severe social and economic burden of stroke is a strong motivation for the exploration of innovative medical approaches. In this context, magnetic resonance (MR) of hyperpolarized (HP) molecular agents via dissolution dynamic nuclear polarization (dDNP ...
EPFL2023Influence of DNP Polarizing Agents on Biochemical Processes: TEMPOL in Transient Ischemic Stroke
Mor-Miri Mishkovsky, Jean-Noël Hyacinthe, Mario Gaetano Lepore, Thanh Phong Kevin Lê, Lara Buscemi Estefanell
Hyperpolarization of 13C by dissolution dynamic nuclear polarization (dDNP) boosts the sensitivity of magnetic resonance spectroscopy (MRS), making possible the monitoring in vivo and in real time of the biochemical reactions of exogenously infused 13C-lab ...
2023Bioaccumulation and molecular effects of carbamazepine and methylmercury co-exposure in males of Dreissena polymorpha
Florian Frédéric Vincent Breider, Dominique Grandjean, Nguyên Thiên Kim Lê, Claudia Cosio
Dreissena polymorpha is a bivalve promising for biomonitoring in freshwater ecosystems thanks to its abundance and high filtration activity allowing rapid uptake of toxicants and identification of their negative effects. Nonetheless, we still lack knowledg ...
2023Advanced metabolite mapping at ultra-high field using 1H-MRS, 1H-MRSI and macromolecules: applications in a rat model of type C hepatic encephalopathy
Magnetic Resonance Spectroscopy (MRS) is the only technique capable of measuring a large number of metabolites simultaneously in vivo. Ultra-high magnetic fields (UHF) combined with ultra-short echo time (TE) sequences allow the detection of high-quality 1 ...
EPFL2022Development 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 ...
EPFL2021Assessment of Aspartate and Bicarbonate Produced From Hyperpolarized [1-13C]Pyruvate as Markers of Renal Gluconeogenesis
Arnaud Comment, Hikari Ananda Infinity Yoshihara
As both a consumer and producer of glucose, the kidney plays a significant role in glucose homeostasis. Measuring renal gluconeogenesis requires invasive techniques, and less invasive methods would allow renal gluconeogenesis to be measured more routinely. ...
2021HP agents and biochemical interactions
Hikari Ananda Infinity Yoshihara
The intense but transient increase in nuclear magnetic resonance signal provided by dynamic nuclear polarization (DNP) has enabled a range of new applications, including rapid, minimally-invasive metabolic imaging at the second timescale. This chapter prov ...
Academic Press2021Phototransformation kinetics of cyanobacterial toxins and secondary metabolites in surface waters
Background Cyanobacteria and their toxins occur in high concentrations during the so-called bloom events in surface waters. To be able to assess the risks associated with cyanobacterial blooms, we need to understand the persistence and fate processes of th ...
SPRINGER2021Magnetic resonance spectroscopy in the rodent brain: Experts' consensus recommendations
Rolf Gruetter, Lijing Xin, Cristina Ramona Cudalbu, Bernard Lanz
In vivo MRS is a non-invasive measurement technique used not only in humans, but also in animal models using high-field magnets. MRS enables the measurement of metabolite concentrations as well as metabolic rates and their modifications in healthy animals ...
WILEY2020Metabolic and hemodynamic changes in the activated human brain and cerebellar organisation measured by MRS/MRl at 7 Tesla
Although less often investigated than the positive blood-oxygen-level-dependent (BOLD) signal, a negative BOLD signal has also been observed under certain conditions, which could have a neuronal origin. To further investigate the negative BOLD signal from ...
