Characterization of hepatic fatty acids in mice with reduced liver fat by ultra-short echo time (1) H-MRS at 14.1 T in vivo

Rolf Gruetter, Ana Francisca Leal Silva Soares, Hongxia Lei

Alterations in the hepatic lipid content (HLC) and fatty acid composition are associated with disruptions in whole body metabolism, both in humans and in rodent models, and can be non-invasively assessed by (1) H-MRS in vivo. We used (1) H-MRS to character ...

Long-lived coupled peeling ballooning modes preceding ELMs on JET

In some JET discharges, type-I edge localised modes (ELMs) are preceded by a class of low-frequency oscillations (Perez et al 2004 Nucl. Fusion 44 609). While in many cases the ELM is triggered during the growth phase of this oscillation, it is also observ ...
