The paper uses in vivo metabolomics to identify neurochemical differences between temperaments linked to SUD vulnerability and shows how cocaine exposure alters these states.

The paper profiles RNA modifications in MS2 bacteriophage using LC-MS/MS and Nanopore DRS, finding {Psi} as the predominant modification.

This paper introduces a method using RNase 4 and HILIC-MS/MS to map tRNA modifications in E. coli with high coverage and without ion-pairing reagents.

This study investigates the neurochemical and neurophysiological effects of DMT in rats, finding dose-dependent increases in serotonin and dopamine and changes in EEG power and functional connectivity.

This paper introduces an offline two-dimensional liquid chromatography-mass spectrometry approach to improve metabolome annotation in fecal samples, identifying more compounds than traditional methods.

This study compares the effects of intermittent and long access cocaine self-administration on dopamine overflow and addiction-like behavior in rodents, finding that intermittent access produces greater incentive and dopamine sensitization.

The paper develops a system to measure opioid peptide release in vivo using optogenetics, microdialysis, and mass spectrometry in freely moving rodents.

The paper shows that dopamine release in forebrain regions correlates with reward expectation, while VTA dopamine cell firing shows error-like responses, suggesting distinct mechanisms for motivation signals.
