A perstraction system using liq.-core microcapsules for pesticide and herbicide removal from aq. environments is proposed. The microcapsules contain an oil, di-Bu sebacate, surrounded by a hydrogel membrane. The extn. efficiency of the capsules was demonst ...
Trace metal bioavailability is often evaluated on the basis of steady-state models such as the free ion activity model (FIAM) and the biotic ligand model (BLM). Some of the assumptions underlying these models were verified by examining Pb and Zn uptake by ...
Lipophilicity of compounds with therapeutic interest represents one of the most important physicochemical parameters in predicting and interpreting transport processes across biological barriers. This property is commonly measured as a drug | membrane part ...
One of revolutionary technologies to sequence single molecules, such as DNA, is using nanopore devices. A single-channel with nanometer-scale aperture allows an extremely rapid electric analysis of such single molecules. The objective of this work is to fa ...
The reaction of the aminophosphane C6H4(o-CN)NHPPh2 with elemental potassium in the presence of 18-crown-6 affords the phosphinoamide-containing complex [C6H4(o-CN)N-PPh2(THF)(18-Crown-6)K] which has been fully characterised in solution and the solid state ...
The functional anal. of single ion channel proteins presents a serious bottleneck in the process of finding new pharmacol. active compds. Currently available single channel recording methods are not suited for automation and miniaturization. However, new t ...
Aerolysin secreted by the human pathogen Aeromonas hydrophila belongs to a group of bacterial toxins that are hemolytic and form channels in biological membranes. The toxin is secreted as an inactive precursor proaerolysin that must be proteolytically proc ...
Tumor necrosis factor TNF can trigger increases in membrane conductance of mammalian cells in a receptor-independent manner via its lectin-like domain. A lectin-deficient TNF mutant, lacking this activity, was able to bind to artificial liposomes in a pH-d ...
Aerolysin is one of a large group of bacterial proteins that can kill target cells by forming discrete channels in their plasma membranes. The toxin has many properties in common with the porins of the Gram-negative bacterial outer membrane, including an e ...
All biol. ion channels are selectively permeable to specific ions. This mechanism needs to be understood in terms of the interaction of the permeating ions with the surrounding water and protein mols. During the past several years, there have been enormous ...
