(Elsevier B.V., 2014-02-01)
Hereditary equine regional dermal asthenia (HERDA) is a genetic disorder that occurs in the American Quarter horse (AQH) and is caused by a c.115G>A missense mutation in the peptidylprolyl isomerase B (PPIB) gene. Using a ...
Quantitative phase determination by using a Michelson interferometer
(IOP Publishing, 2007-09)
The Michelson interferometer is one of the best established tools for quantitative interferometric measurements. It has been, and is still successfully used, not only for scientific purposes, but it is also introduced in ...
Quantitative determination of maitenin and 22 beta-hydroxymaitenin in callus of Maytenus aquifolium (Celastraceae) by reverse phase high performance liquid chromatography
(Wiley-Blackwell, 1998-09-01)
Explants of Maytenus aquifolium were induced to form callus and, subsequently, suspension cultures. The isolation of natural products from callus led to the identification of the cytotoxic triterpene quinonemethides, ...
