A Thermodynamic Study on Hydration and Dehydration of DNA and RNA −Amphiphile Complexes
نویسنده
چکیده
In the current opinion, we would like to study adhesion of DNA and RNA−amphiphile complexes to non–modified glasses, glasses containing phenylboronic acid (PBA) attached via 3– glycidoxypropyltrimethoxysilane (GPTMS) [(PBA–GPTMS–glasses)] and glasses containing grafted dimethyllacrylamide–acrylamide phenylboronic acid (DMAA–AAPBA) copolymer (DMAA–AAPBA– glasses). We prepared glasses modified with GPTMS and then attached PBA to them. After that, we modified glasses by (3–mercaptoropyl) trimethoxy silane (MPTMS) and grafted DMAA–AAPBA copolymer to the modified glass plates. For increasing the measuring sensitivity, DNA and RNA−amphiphile complexes were stained with Procion Red HE3B, Red 4GE, Red 510, Red KE3B, Red 120, Red ABO, Red A4G, Red 3B, Red KE3B, Red HE3G, Red 53 L, Red HE3BI, Red E3B, Red CT3B, Red ES3B, Red LHE3B, Red I3B, Red HE3BFC, Red MEB, Red SE3BI, Red 24990, Red SE3B, Red 3BHE and other active and reactive dyes. DNA and RNA−amphiphile complexes stained with Procion Red HE3B, Red 4GE, Red 510, Red KE3B, Red 120, Red ABO, Red A4G, Red 3B, Red KE3B, Red HE3G, Red 53 L, Red HE3BI, Red E3B, Red CT3B, Red ES3B, Red LHE3B, Red I3B, Red HE3BFC, Red MEB, Red SE3BI, Red 24990, Red SE3B, Red 3BHE and other active and reactive dyes formed denser and more stable layer on the copolymer–grafted supports compared onto supports modified with phenylboric acid via a organosilane spacer [1–18]. Adhesion of DNA and RNA−amphiphile complexes to boronate–containing polymer fixed on solid support in different conditions such as pH, precipitation time and different concentrations of glucose (dextrose), fructose (levulose) and galactose were studied.

Modeling of the hydration shell of Adenine
The molecular geometry of complex of adenine with 8 water molecules was calculated with Hartree-Fock (HF). The standard 6-31G(d) basis set has been employed. The existence of C-H…O Hydrogen bonds between the water molecules and the hydrophobic part of nucleobase is stablished. We optimized structures and computed interaction energies of all complexes of adenine with water molecules step by step...
متن کاملInvestigation of the effect of phosphate agent type on setting time, flowability, hydration and dehydration of magnesium phosphate cement.
Magnesium phosphate cements (MPC) are the most developed kind of chemically bonded ceramics which form through the reaction of magnesium oxide and soluble phosphate salts. Therefore, study of different magnesium phosphate cement systems is considered important according to the type of phosphate agent used. In this study, effect of mono-ammonium phosphate (MAP), di-ammonium phosphate (DAP), and ...

The production of ordinary Portland cement (OPC) as the most expensive constituent of concrete is associated with destructive environmental effects and significant energy consumption. Thus, the use of supplementary cementitious materials such as Natural or synthetic pozzolans is a fundamental solution that affects the kinetics of hydration of cementitious materials. In this article, to evaluate...
متن کاملCharge inversion in DNA-amphiphile complexes: Possible application to gene therapy
We study a complex formation between the DNA and cationic amphiphilic molecules. As the amphiphile is added to the solution containing DNA, a cooperative binding of surfactants to the DNA molecules is found. This binding transition occurs at specific density of amphiphile, which is strongly dependent on the concentration of the salt and on the hydrophobicity of the surfactant molecules. We find...
