In vivo H-1 NMR measurement of glycine in rat brain at 9.4 T at short echo time

Rolf Gruetter, Lijing Xin, Giulio Gambarota, Chiara Perazzolo

Glycine is an amino acid present in mammalian brain, where it acts as an inhibitory and excitatory neurotransmitter. The two detectable protons of glycine give rise to a singlet at 3.55 ppm that overlaps with the more intense myo-inositol resonances, and i ...

Bridging structural MRI with cognitive function for individual level classification of early psychosis via deep learning

Lijing Xin

IntroductionRecent efforts have been made to apply machine learning and deep learning approaches to the automated classification of schizophrenia using structural magnetic resonance imaging (sMRI) at the individual level. However, these approaches are less ...

Metabolic and transcriptomic profiles of glioblastoma invasion revealed by comparisons between patients and corresponding orthotopic xenografts in mice

Cristina Ramona Cudalbu Moldovan, Lijing Xin, Mario Gaetano Lepore, Marta Lai

The invasive behavior of glioblastoma, the most aggressive primary brain tumor, is considered highly relevant for tumor recurrence. However, the invasion zone is difficult to visualize by Magnetic Resonance Imaging (MRI) and is protected by the blood brain ...
