Cell adhesion and the adhesion of vesicles to the membranes of cells or organelles are pivotal for immune responses, tissue formation, and cell signaling. The adhesion processes depend sensitively on the binding constant of the membrane-anchored receptor and ligand proteins that mediate adhesion, but this constant is difficult to measure in experiments. We have investigated the binding of membr...

     Most of the biological phenomena are influenced by intermolecular recognition and interaction. Thus, understanding the thermodynamics of biomacromolecule ligand interaction is a very interesting area in biochemistry and biotechnology. One of the most powerful techniques to obtain precise information about the energetics of (bio) molecules binding to other biological macromolecules is isoth...

Organometallic complexes offer potential for design as anticancer drugs. A quantitativemodel that discriminates anticancer compounds from the inactive ones in a training series wasEquilibrium of the reaction of molybdenum (VI) with l-histidine have been studiedin aqueous solutions at pH range of 4-8, using spectrophotometry and optical rotationmethods at constant ionic strength of 0.15 mol.lit-...

In this study, we were synthesized Fe3O4@LDH@Lamivudine and characterized by FT-IR spectroscopy,XRD and TEM. The interaction of this nanoparticle with CT-DNA was investigated by viscosity, circulardichroism (CD), Uv-Visible and fluorescence spectroscopy. Among all nanocarriers which applied as drugdelivery vectors, layered double hydroxides (LDHs) with exchangeable anions in t...

Several series of shallow large-size (l ≫ lattice spacing) two-hole bound states are found in the two-dimensional t−J model. Their binding energies depend exponentially on the inverse value of the hole-spin-wave coupling constant. Their parity is connected with the angular wave function in a nonstandard way. The possible role of these states in the formation of superconducting pairing is consid...

The submillisecond kinetics for phloretin binding to unilamellar phosphatidylcholine (PC) vesicles was investigated using the temperature-jump technique. Spectrophotometric studies of the equilibrium binding performed at 328 nm demonstrated that phloretin binds to a single set of independent, equivalent sites on the vesicle with a dissociation constant of 8.0 microM and a lipid/site ratio of 4....

curcumin (cur) is the active curcuminoid with many physiological, biochemical, and pharmacological properties. solubility and stability of cur is the limiting factors for realizing its therapeutic potential. bovine β-casein is an abundant milk protein that is highly amphiphilic and self-assembles into stable micellar nanoparticles in aqueous solution. β-casein nanoparticle can solubilize cur mo...

Monte Carlo simulations are used to calculate the binding constant of two Ca2+ ions to the protein bovine calbindin D9k. The change in binding constant with respect to mutation of charged amino acids, presence of various electrolytes, protein concentration, solution pH, and competitive binding of monovalent ions is investigated. Each of these factors may have a large influence on the binding co...
