systematic studies on the vapor-liquid equilibria (vle) and conductometric properties of aqueous solutions of model surface-active ionic liquid 1-dodecyl-3-methylimidazolium bromide ([c12mim]br) are performed in the absence and presence of a large series of electrolytes in order to achieve a deeper understanding about the molecular mechanism behind the specific salt effect on the aggregation be...

a thermodynamic study on the interaction between zinc ion (zn2+) and human growth hormone(hgh) was studied at two temperatures of 27c and 37c in aqueous solution using an isothermal titrationcalorimetry. it was found that there is a set of three identical and non-interacting binding sites for zn2+ ions. the intrinsic dissociation equilibrium constant and the molar enthalpy of binding are 1.54...

a thermodynamic study of copper ions by jack bean urease (jbu) was carried out at two temperatures of 27 and 37?c in tris buffer (30 mm; ph=7.0) using an isothermal titration calorimetry. there is a set of twelve identical and non-interacting binding sites for copper ions. the intrinsic dissociation equilibrium constant and the molar enthalpy of binding are 285 µm and ?15.2 kj/mol at 27?c and 3...

Ribonucleoprotein (RNP) granules are enriched in specific RNAs and RNA-binding proteins (RBPs) and mediate critical cellular processes. Purified RBPs form liquid droplets in vitro through liquid-liquid phase separation and liquid-like non-membrane-bound structures in cells. Mutations in the human RBPs TAR-DNA binding protein 43 (TDP-43) and RNA-binding protein FUS cause amyotrophic lateral scle...

The study of the interaction between DNA and small molecules such as drugs is one of the current general interest and importance. In this paper, the electrochemical investigation of the interaction between some flavonoids such as rutin, quercetin, and hesperidin with dsDNA on the surface of Supramolecular Ionic Liquid grafted on the Graphene Oxide Modified Glassy Carbon Electrode (</s...

a novel ternary schiff base ligand (hl) of ono type and its copper (ii) complex weresynthesised using 2-aminophenol and o-acetoacetotoluidide. they have been characterised by theusual analytical and spectral methods. the interaction of the complex with calf-thymus (ct)dna has been investigated by uv-vis, viscosity measurement, cyclic voltammetry anddifferential pulse voltammetry studies. the re...

Abstract Cellular liquid–liquid phase separation is a physiologically inevitable phenomenon in molecularly crowded environments inside cells and serves to compartmentalize biomolecules facilitate several functions, forming cytoplasmic nuclear RNA granules. Abnormalities the process granules are implicated onset of neurodegenerative diseases; initial liquid-like phase-separated droplets containi...

Liquid crystals are rigid organic molecules that exhibit orientational behavior on surfaces. The orientation of liquid crystals can be controlled by the design of surfaces with regular nanoscale features and/or defined chemistries. The orientation of liquid crystals on such surfaces can be exploited to sensitively report the binding of proteins to the surface [1-6]. Liquid crystal based detecti...

[structure: see text] A new system for the double amplification of the molecular chirality of simple chiral amines in achiral liquid crystalline media is described. It involves a conformationally flexible phosphoric acid based receptor that by binding to chiral amines induces chirality in the liquid crystalline matrix. Efficient cholesteric phase formation was shown by several chiral amines tha...
