Lipid hydroperoxidation effect on the dynamical evolution of the conductance process in bilayer lipid membranes: A condition toward criticality
(American Chemical Society, 2020-08-04)
Cell membranes are one of the main targets of oxidative processes mediated by reactive oxygen species (ROS). These chemical species interact with unsaturated fatty acids of membrane lipids, triggering an autocatalytic chain ...
Lipids at the crossroad of α-synuclein function and dysfunction: Biological and pathological implications
(Frontiers Media S.A., 2019-05-01)
Since its discovery, the study of the biological role ofα-synuclein and its pathologicalimplications has been the subject of increasing interest. The propensity to adoptdifferent conformational states governing its aggregation ...
Mechanical stability of lipid membranes decorated with dextran sulfate
(American Chemical Society, 2018-09)
Lipid vesicles decorated with polysaccharides have been proposed as vehicles for drug delivery because the polymers confer to the vesicles an enhanced stability, increasing the probability of the drug for reaching the ...
Interaction of green silver nanoparticles with model membranes: Possible role in the antibacterial activity
(Elsevier Science, 2018-11)
Silver nanoparticles (AgNPs) constitute a very promising approach for overcoming the emergence of antibiotic resistance bacteria. Although their mode of action could be related with membrane damage, the AgNPs-lipid membrane ...
Effect of organochlorine insecticides on nicotinic acetylcholine receptor-rich membranes
(Pergamon-Elsevier Science Ltd, 2000-05)
The so-called generalized polarization (GP) of the fluorescent probe Laurdan and the steady-state fluorescence anisotropy of the probe diphenylhexatriene (DPH) and its phenylpropionic derivative (PA-DPH) were used to study ...
A closer look into the physical interactions between lipid membranes and layered double hydroxide nanoparticles
(Elsevier Science, 2020-07)
Layered double hydroxide nanoparticles (LDH-NPs) constitute promising nanocarriers for drug and gene delivery. Although their cell internalization has been studied, the interaction between LDH-NPs and biological membrane ...
Factors influencing the membrane fluidity and the impact on production of lactic acid bacteria starters
(Springer, 2019-09)
Production of lactic acid bacteria starters for manufacturing food, probiotic, and chemical products requires the application of successive steps: fermentation, concentration, stabilization, and storage. Despite process ...
Interaction of gabaergic ketones with model membranes: A molecular dynamics and experimental approach
(Elsevier Science, 2018-08)
γ-Aminobutyric-acid receptor (GABA A -R), a membrane intrinsic protein, is activated by GABA and modulated by a wide variety of recognized drugs. GABA A -R is also target for several insecticides which act by recognition ...
Agonist mobility on supported lipid bilayers affects Fas mediated death response
(Elsevier Science, 2015-11-30)
Extrinsic apoptosis is initiated by recognition and clustering of the single-pass transmembrane proteins Fas ligand and Fas expressed at the surface of closely apposed lymphocytes and target cells, respectively. Since ...
Effects of photooxidation on membrane integrity in Salix nigra seeds
(Oxford University Press, 2010-06)
Background and Aims: Salix nigra seeds are desiccation-tolerant, as are orthodox seeds, although in contrast to other orthodox seeds they lose viability in a few weeks at room temperature. They also differ in that the ...
