Oxidative potetial of atmospheric aerosol as indicator of ROS formation
Barboříková, Hana ; Mikuška, Pavel ; Hegrová, J. ; Krajčovič, J.
Atmospheric particulate matter (PM) affects our environment especially human health because it contains many toxic chemical substances. The purpose of this study is to determine a total content and a soluble fraction of selected metals and also the contribution of metals soluble in pulmonary fluids to a total oxidative potential of PM.
Mixed lipids and their interaction with biopolymers
Barboříková, Hana ; Smilek, Jiří (referee) ; Mravec, Filip (advisor)
This thesis focuses on the study of interactions between hyaluronan and lipid DOTAP and its mixtures with DPPC in water. First, the aggregation behavior of the lipid itself and its mixtures was measured, afterwards the influence of hyaluronan in different concentration was studied. Further the fluorescence anisotropy of fluorescence probe DPH in these mixtures and influence of cholesterol was measured. These properties were investigated by fluorescence spectoscopy using pyrene and DPH as fluorescence probes. The measurements revealed that the addition of hyaluronan has observable influence on the aggregation behavior of the lipid DOTAP and its mixtures with DPPC and that cholesterol influences liposomes fluidity.
Study of the interaction of hyaluronan and biocompatible amphiphilic substances
Barboříková, Hana ; Krouská, Jitka (referee) ; Mravec, Filip (advisor)
This thesis focuses on the study of the interactions between hyaluronan and selected phospholipids and their mixtures in water or buffer. First, the aggregation behavior of these lipids was measured, afterwards the influence of hyaluronan was studied. This behavior was investigated by fluorescence spectoscopy using pyrene as fluorescence probe. The Critical Agregation Concentration of the lipids before and after addition of hyaluronan was determined. The measurements revealed that the addition of hyaluronan has an observable influence on the aggregate behavior of the selected lipids and their mixtures.
