Lipid exchanges between dioctadecyldimethylammonium bromide monolayer and vesicles in the subphase
(2022-03-01)
Studies on the interaction of lipid monolayer with bilayer structures, such as vesicles, are relatively scarce in the literature. In order to ascertain whether these structures interact for cationic dioctadecyldimethylammonium ...
Chemical and morphological effects of the contraceptive hormone 17 α-ethynylestradiol on fluid lipid membranes
(2021-08-01)
The lack of studies involving the effects in human health associated with the chronic ingestion of pollutants lead to the path of investigating the action of these compounds in cell membrane models. We demonstrated the ...
Consequences of the exposure to bisphenol A in cell membrane models at the molecular level and hamster ovary cells viability
(2021-07-01)
The inadequate disposal and the difficulty in its removal from water treatment systems have made the endocrine disruptor bisphenol A (BPA) a significant hazard for humans and animals. The molecular-level mechanisms of BPA ...
The assembly of dialkyldimethylammonium bromide cationic lipids as vesicles or monolayers in presence of poly(ethylene glycol)
(Elsevier B.V., 2015-08-10)
The interaction between polymer and lipid vesicles may result in stabilization and formation of highly ordered networks, which can mimic biological membranes and be used as drug delivery system. Here we used differential ...
Effects of insecticide acephate on membrane mimetic systems: The role played by electrostatic interactions with lipid polar headgroups
(2021-06-15)
Pesticides are important agrochemicals to yield high crop productivity but their indiscriminate use may harm the environment and human health. In order to seek a compromise between effectiveness as insecticide and safety ...
Correlating mono- and bilayers of lipids to investigate the pronounced effects of steroid hormone 17α-ethynylestradiol on membrane models of DPPC/cholesterol
(2020-08-01)
Risks to human health have been reported owing to prolonged exposure to hormones, whose action depends on their molecular-level interaction with cell membranes. In this study, we investigate the interaction of the synthetic ...
Interactions of Lipid Polar Headgroups with Carbendazim Fungicide
(Amer Scientific Publishers, 2019-07-01)
Carbendazim (MBC) is a fungicide widely used in agriculture which allows the high productivity of several cultures, a necessary condition considering the growing of the world population. Moreover, MBC has environmental ...
Cholesterol induces surface localization of polyphenols in model membranes thus enhancing vesicle stability against lysozyme, but reduces protection of distant double bonds from reactive-oxygen species
(Elsevier Science, 2016-07)
The main scope of the present study was to analyze the membrane interaction of members of different classes of polyphenols, i.e. resveratrol, naringenin, epigallocatechin gallate and enterodiol, in model systems of different ...
The importance of cyclic structure for Labaditin on its antimicrobial activity against Staphylococcus aureus
(Elsevier B.V., 2016-12-01)
Antimicrobial resistance has reached alarming levels in many countries, thus leading to a search for new classes of antibiotics, such as antimicrobial peptides whose activity is exerted by interacting specifically with the ...
Molecular-Level Modifications Induced by Photo-Oxidation of Lipid Monolayers Interacting with Erythrosin
(2016-05-03)
Incorporation into cell membranes is key for the action of photosensitizers in photomedicine treatments, with hydroperoxidation as the prominent pathway of lipid oxidation. In this paper, we use Langmuir monolayers of ...
