Alpha-1-antitrypsin: a novel human high temperature requirement protease A1 (HTRA1) substrate in human placental tissue. [PDF]
PLoS ONE, 2014 The human serine protease high temperature requirement A1 (HTRA1) is highly expressed in the placental tissue, especially in the last trimester of gestation. This suggests that HTRA1 is involved in placental formation and function.

Advanced simulation code for alpha spectrometry [PDF]
Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2005 A Monte Carlo code, known as AASI, is developed for simulating energy spectra in alpha spectrometry. The code documented here is a comprehensive package where all the major processes affecting the spectrum are included. A unique feature of the code is its ability to take into account coincidences between the particles emitted from the source ...

Identification of bile alcohols in rat bile.
Journal of Lipid Research, 1989 Bile alcohols in rat bile were analyzed by gas-liquid chromatography-mass spectrometry. Six bile alcohols were newly identified as minor constituents in addition to 5 beta-cholestane-3 alpha,7 alpha,12 alpha,26-tetrol, major bile alcohol of rat bile. The
