HepG2 and HeLa cells were incubated for 5 or 16 h under hypoxia or normoxia in the presence or absence of increasing concentrations of echinomycin. ... effect is caused by an increase in HIF-1a pro- tein level, resulting from an increase in the transcription of the HIF-1A gene in the presence of a low concentration of echino...

... samples of words serve as input to the training procedure. In a treebank training step we observe for each rule in the training grammar how often it is used for the training corpus. The grammar rules ... want to examine the in- fluence of the size of the training corpus on the results of the evaluation. Therefore, we split the training corpus into 9 corpora, where...
