Oxygen toxicity is one of the major risk factors in the development of the chronic lung disease or bronchopulmonary dysplasia in premature infants. Using proteomic analysis, we discovered that mitochondrial aldehyde dehydrogenase (mtALDH or ALDH2) wa

A capillary gas chromatograph/Fourier transform mass spectrometer (GC/FTMS) has been upgraded so that a pulsed laser operating at 266 nm can be used for multiphoton ionization (MPI). MPI is demonstrated to be a selective ionization method for a varie
