Development of a Reliable Analytical Protocol for the Isolation of Cholesterol Oxidation Products—a Comparison of Different Lipid Extraction and Saponification Methods
Constantinou, Michalis S.; Georgiou, Christiana A.; Kapnissi‐Christodoulou, Constantina P. (2015)The main objectives of this study were (i) the optimization and the validation of a high performance liquid chromatographic method for the simultaneous determination of seven cholesterol oxidation products (COPs), (ii) the ...

The ion-lipid battle for hydration water and interfacial sites at soft-matter interfaces
Leontidis, Epameinondas; Christoforou, Maria; Georgiou, Christiana A.; Delclos, Thomas (2014)At charged surfaces "bound" ions reduce the repulsive electrostatic forces, while dissociated ions control the osmotic pressure in colloidal systems. For systems charged through ionic adsorption on the other hand, the ...

Sample preparation: A critical step in the analysis of cholesterol oxidation products
Georgiou, Christiana A.; Constantinou, Michalis S.; Kapnissi‐Christodoulou, Constantina P. (2014)In recent years, cholesterol oxidation products (COPs) have drawn scientific interest, particularly due to their implications on human health. A big number of these compounds have been demonstrated to be cytotoxic, mutagenic, ...
