Fifteen men with schizophrenia and 15 normal controls were presented with a photograph of a Noh mask rotated either upward or downward from the neutral front-facing position, and an emotion label, and(More)
In order to demonstrate the potential of plant cell culture systems to produce a target natural bioactive compound, we proposed a stepwise protocol for β-thujaplicin production as follows. 1. Induction phase: Characteristics of callus cultures originating from newly flushed shoots of 10 conifer species were evaluated on different basal media such as(More)
A dynamic headspace extraction method (DHS) with high-pressure injection is described. This dynamic extraction method has superior sensitivity to solid phase micro extraction, SPME and is capable of extracting the entire gas phase by purging the headspace of a vial. Optimization of the DHS parameters resulted in a highly sensitive volatile profiling system(More)
