Let A be a bialgebra, R ∈ A A be a strong “cocycle”. It will be shown that the monoidal category _Auhas a braided monoidal subcategory and several equivalent conditions for (A, R ) to be a quasitriangular bialgebra will be given. Furthermore, it will be shown that A contains a finite dimensional subbialgebra which is a quasitriangular Hopf algebra if R is a YB-operator.

The apoptosis protection by plasminogen activator inhibitor-2(PAI-2) is dependent on a 33 amino acid fragment between helix C and D of PAI-2 which is probably due to the interaction of PAI-2 with unknown intracellular proteins. In this study, we used the fragment between helix C and D of PAI-2 as bait to screen a HeLa cell cDNA library constructed during apoptosis in a yeast two-hybrid system and retrieved a clone encoding 241 amino acids of proteasome (prosome, macropain) subunit, beta type l(PSMβ1) which plays important roles in NF-jjjjjjjjB activation. GST-pulldown experiments confirmed the interaction between PAI-2 and PSMβ1 in vitro. These data suggest that the antiapoptosis activity of PAI-2 is probably related to its interation with PSMβ1.

Recombinant proteins that combine different functions required for cell targeting and intra- cellular delivery of DNA present an attractive approach for the development of nonviral gene delivery vectors. Here, we described a novel protein termed ATF-lys10 which facilitated cell-specific gene transfer via receptor-mediated endocytosis. ATF-lys10 was composed of the amino-terminal fragment of urokinase and ten lysines at the carboxyl terminus. Bacterially expressed ATF-lys10 protein existed in soluble form, and had antigenicity of human urokinase. Purified ATF-lys10 specifically bound to uPAR-expressing cells and formed protein-DNA complexes with plasmid pGL3-control. After neutralization of excess negative charge with poly-L-lysine, these complexes served as a specific gene delivery vector for uPAR-expressing cells. Lyso- somotropic compounds, such as chloroquine, drastically increased the ATF-lys10 mediated gene delivery efficiency. Our results suggest that the recombinant protein ATF-lys10 with the properties of DNA binding and tumor cell targeting represents a promising method for gene transfer and expression in tumor cells.

In this paper. we use the improved closed-loop control method to realizethat the discrete chaotic system stabilizes to any arbitrarily chosen dynamics. We givethe strict proof as well as the general result of 2-dimensional system to show the feasibiltyof our method and criterion. Furthermore, the well-known Henon system is chosen foran example and the corresponding computer simulation results are given to support ourmethod.

This paper establishes a limit theorem for solutions of backward stochastic differential equations (BSDEs). By this limit theorem, this paper proves that, under the standard assumption g(t,y,0) = 0, the generator g of a BSDE can be uniquely determined by the corresponding g-expectationεg;this paper also proves that if a filtration consistent expectation S can be represented as a g-expectationεg, then the corresponding generator g must be unique.
