Influence of C-Trap Ion Accumulation Time on the Detectability of Analytes in IR-MALDESI MSI
ANALYTICAL CHEMISTRY, 87(20), 10483–10490.
MeSH headings : Ions / chemistry; Lasers; Spectrometry, Mass, Electrospray Ionization; Spectrometry, Mass, Matrix-Assisted Laser Desorption-Ionization; Spectrophotometry, Infrared; Time Factors; Xenobiotics / analysis
TL;DR:
Reducing the C-trap ion accumulation time resulted in increased ion abundance by up to 3 orders of magnitude for analytes ranging from xenobiotics to endogenous lipids, and facilitated the reduction of voxel-to-voxel variability by more than 3-fold.

Mass Spectrometry Imaging Reveals Heterogeneous Efavirenz Distribution within Putative HIV Reservoirs
ANTIMICROBIAL AGENTS AND CHEMOTHERAPY, 59(5), 2944–2948.
MeSH headings : Alkynes; Animals; Anti-Retroviral Agents / pharmacokinetics; Benzoxazines / pharmacokinetics; Cyclopropanes; Gray Matter / metabolism; Lymph Nodes / metabolism; Macaca; Mass Spectrometry / methods
TL;DR:
Intratissue efavirenz distribution was heterogeneous, with the drug concentrating in the lamina propria of the colon, the primary follicles of lymph nodes, and the brain gray matter, the first imaging data of an antiretroviral drug in active viral reservoirs.
