Certain hormonal and nonhormonal binding systems such as the leukoagglutinin-lymphocyte model exhibit complex receptor-ligand interactions that result in nonlinear Scatchard plots. Such plots are interpreted as indicating either homogeneous negatively interacting binding sites or heterogeneous sites with different and fixed affinity. We assessed the validity of these interpretations in our syst...

We introduce a new smooth, non-toxic, biocompatible method for cross-linking of gum tragacanth (GT), a polysaccharide of natural origin, in order to serve as a new supporting matrix for immobilization systems.  The modified gum is used as a matrix for the catalysis of the conversion of benzyl penicillin to 6-aminopenicillanic acid (6-APA) by means of Escherichia coli ATCC11105 with penicill...

This paper describes the THUNLP system submitted to Entity Linking task of KBP Track in TAC 2013. This system achieves the third place with a B-cubed+ F1 score of 0.712 in mono-lingual entity linking task. In Chinese cross-lingual entity linking, this system achieved B-cubed+ F1 score of 0.647 with the help of Google Translate.

To determine whether the toxic effects and changes in many cell functions caused by antitumor 1-nitroacridines are related to their enzymatically mediated covalent interstrand DNA crosslinking (J. Konopa, J. W. Pawlak, and K. Pawlak. Chem.-Biol. Interact., 43: 175-197, 1983), the cross-linking potency of the derivatives with structural modifications in position 9 of the acridine nucleus was est...

In this work, we used a simple and totally green method for synthesizing silver nanoparticles using kappa-carrageenan as reducing and stabilizing agent. The beads were prepared in aqueous medium by microwave heating, and then followed by cross-linking with K+ cations without using any additional toxic and expensive chemical agents. The preparation method of the carrageenan-based beads is easy, ...

In this paper, we describe the University of Illinois (UI CCG) submission to the 2013 TAC KBP English Entity Linking (EL) and Slot Filler Validation (SFV) tasks. We developed two separate systems. Our Entity Linking system integrates an improved version of the Illinois Wikifier with additional functionality to identify and cluster entity mentions that do not correspond to entries in the referen...
