A Simple Flow Injection Analysis–Tandem Mass Spectrometry Method to Reduce False Positives of C5-Acylcarnitines Due to Pivaloylcarnitine Using Reference Ions Open
Flow injection analysis–tandem mass spectrometry (FIA-TMS) has been applied in a first-tier test of newborn screening (NBS). Although isovalerylcarnitine (i-C5), which is a diagnostic indicator of isovaleric acidemia (IVA), is isobaric wit…

Fecal metabolite analysis of Japanese macaques in Yakushima by LC-MS/MS and LC-QTOF-MS Open
We performed a comprehensive fecal metabolite analysis using LC-MS/MS and LC-QTOF-MS approaches as a preliminary study. Feces of Japanese macaques on Yakushima Island were collected from five monkeys at two separate locations. Using the fo…

Metabolomic LC-MS/MS analyses and meta 16S rRNA gene analyses on cecal feces of Japanese rock ptarmigans reveal fundamental differences between semi-wild and captive raised individuals Open
Ex situ conservation of Japanese rock ptarmigans began in 2015 with the aim of reintroducing artificially raised birds into their original habitat. However, the current raising method in captivity seems insufficient in terms of the surviva…

Free D-amino acids produced by commensal bacteria in the colonic lumen Open
D -amino acids ( D -AAs) have various biological activities, such as activation of N -methyl- D -aspartic acid (NMDA) receptor as a co-agonist by D -Ser. Since several free D -AAs are released in the broth monocultured with bacterium and D…

Highly sensitive tITP‐CZE determination of <span>l</span>‐histidine and creatinine in human blood plasma using field‐amplified sample injection with mobility‐boost effect Open
2D computer simulation revealed that amino acids and weak electrolytes were cationized because of the migration of counter‐ion from a BGE zone to a sample zone, which encouraged electrokinetic injection (EKI) of these analytes (by the mobi…
