... cells in the absence of fibronectin, although the binding was reducedcompared to the binding seen when fibronectin was included(Table 3). In conclusion, the data demonstrate that M pro-tein-expressing ... depends on electrostatic interactions between the negatively charged sulfate groups of the GAGchains and positively charged regions of the ligand. Typi-cally, the heparin-binding domains of known ... CS and DSdiffer mainly in the epimerization of the uronic acid(glucuronic acid in CS and IdoA in DS; Fig. 1A) and IdoAis also present in significant amounts in HS6 and heparin. The presence of...

We must imposerestrictions on values of some features (i.e., ignor-ing them) and/ or the number of rule applications in order to guarantee the termination of the rule appli-cation. ... the elimination of impossible parse trees in phase 2 areperformed. In the following sections, we briefly de-scribe the CF approximation and the elimination of impossible parse trees in each ... traversal startingfrom roots of successful context-free derivations. In phase 2, it then eliminates invalid parse trees by us-ing constraints in the given grammar. We call the remaining edges that...

... f(TAB) relation is the stand structure, whichis dependent on both tree age and silviculture. The denser the stand, the stronger the light extinction in the canopy and the smaller the living part ... TAB concentration in comparison of stands of the same biomass. This kind of variability may decrease the statistical significance of the relationships between TAB and its nutrient amount. The ... part of the tree crown.Considering the large difference in chemical composition between the stem and the crown, the variation of the crown biomass: tree biomass ratio can lead to a change in the...
