Comparative Study of Surface-Active Properties and Antimicrobial Activities of Disaccharide Monoesters

The objective of this research was to determine the effect of sugar or fatty acid in sugar ester compounds on the surface-active properties and antimicrobial activities of these compounds. Disaccharides of medium-chain fatty acid monoesters were synthesized through transesterifications by immobilized lipase (Lipozyme TLIM) to yield nine monoesters for subsequent study. Their antimicrobial activ...

Intracellular ferriprotoporphyrin IX is a lytic agent.

Human erythrocytes were treated with menadione to oxidatively denature hemoglobin and release ferriprotoporphyrin IX (ferriheme, FP) intracellularly. The high affinity of FP for chloroquine was used to detect its release. After incubation for 1 hr at 37 degrees C and pH 7.4 with 0.5 mM menadione, erythrocytes bound 14C-chloroquine with an apparent dissociation constant of 10(-6)M. Untreated ery...

Influence of Surface Heterogeneities on Complexation of Ethylene with Active Sites of NiMCM-41 Nanocatalyst: A Density Functional Theory Study

Consecutive adsorption of ethylene molecules on different nanoclusters as representatives of the active sites of NiMCM-41 catalyst was investigated with respect to structural, topological, and energetic properties at the B3LYP/6-311+G* and M06/Def2-TZVP levels of theory. The dimeric adsorption of the ethylene molecules was found to be exothermic on all sites (adsorption enthalpies ranging from ...

Active Texture Synthesis Based on Multi-agent

In this paper, we propose a novel active texture synthesis algorithm based on multi-agent, aiming at overcoming some drawbacks of existing popular patch-based methods. By defining agents’ attributes and behaviors, we dexterously convert the texture synthesis issue to an optimization problem. It can quickly achieve high-quality results for a wide variety of textures without any extra overhead fo...
