... spectrum (Fig. 6B), all the expected correlations from 3-CH in the A-ring are the same as in the parent vitamin D3. This further confirms that no hydroxylation occurs in the A-ring. The new hydroxylated ... by sonication for 10 min in a bath-type sonicator [22]. Vitamin D3, cholesterol and hydroxyvitamin D3 derivatives were included in the mixture for sonication as...

... should be involved in the procedure for their ex- traction. We incorporate context information in the form of weights constructed in a fully automatic way. 2.1 The Linguistic Part The corpus ... f(a) the frequency of a in the corpus, Ta the set of candidate terms that contain a, P(T~) the number of these candidate terms. At this point the incorporation of...

... (2002) combined an information gain-like metric and the perplexity reduction criterion for lexicon word se- lection. The application is on Chinese pinyin-to- character conversion, which has very ... such information. With the baseline lexicon, we performed the EM algorithm as in Table 2 to train the trigram LM. Here we used a 313 MB LM training corpus, which contains text news...

... Bax and Bad bind 14-3-3, the phosphoserine ⁄ threonine binding proteins in the cytosol. 14-3-3 prevents Bax and Bad dissociation from translocating to the mitochondria by a conformation change, ... by containing a Ser139 phosphorylation site in the C-terminal tail. Phosphorylation of H2AX on Ser139 is a key event in the repair of DNA damage and the induction of DNA degrada...

If this is the case, the bind- ing enthalpy is dependent on the ionization enthalpy of the buffer in which the reaction takes ... An exception would be the NapD chaperone having a fer- redoxin-type fold, which undergoes only minor confor- mational changes upon binding the twin-arginine signal peptide...

Another possible explanation for the observed autoinhibitory ... a-helix within the HD that is the primary DNA-binding region, although there are other DNA contacts outside helix 3 [4–7]. In addition to binding DNA, the HD is a protei...
