Effects of transmembrane potential and pH gradient on the cytochrome c-promoted fusion of mitochondrial mimetic membranes
(Springer, 2013-08-01)
The present study investigated the effects of Delta I and Delta pH (pH gradient) on the interaction of cytochrome c with a mitochondrial mimetic membrane composed of phosphatidylcholine (PC), phosphatidylethanolamine (PE), ...
Molecular interactions of an ornithine-rich pH-responsive self-Assembling peptide with a model lipid membrane: Conformational aspects
(2016-09-01)
Investigating interactions of designed peptide-based biomaterials with lipid membranes is important for applications in nanobiotechnology. Here the interaction of an ornithine-rich pH-responsive peptide called P11-5 with ...
Chitosan Associated with the Extract of Unripe Banana Peel for Potential Wound Dressing Application
(Hindawi Ltd, 2017-01-01)
Theauthors report the preparation of chitosanmembranes associated with the extract of unripe banana peel. Extractswere prepared by decoction, using boiling distilled water. The extraction process was repeated three times. ...
Synthesis and characterization of perovskite materials for production of mixed ionic and electronic conduction membranes
(Universidade Federal de Minas GeraisUFMG, 2016-01-27)
The need of a clean energy delivery is increasing daily with the changes taking place around the planet. Oxygen separation methods for coal power plants are a good option to reach the demands and goals, since some idealized ...
Evaluation of antibacterial activity of chitosan membranes associated to unripe banana peel
(2016-01-01)
The treatment of skin wounds is a worldwide problem due to possible complications of healing process, such as infections, sepsis and even death. Current treatment strategies involves the use of dressings, bandages and ...
Morphology of Electrospun Non-Woven Membranes of Poly(vinylidene fluoride-co-hexafluoropropylene): Porous and Fibers
(2019-03-01)
In this paper, poly(vinylidene fluoride-co-hexafluoropropylene) nanofibers membranes were fabricated by facile single-capillary electrospinning at different times of production. The materials were characterized by ...
Structural associations between organelle membranes in nectary parenchyma cells
(2018-05-01)
Main conclusion: The close association between membranes and organelles, and the intense chloroplast remodeling in parenchyma cells of extrafloral nectaries occurred only at the secretion time and suggest a relationship ...
Effects of artepillin c on model membranes displaying liquid immiscibility
(2019-01-01)
It has been hypothesized that the therapeutic effects of artepillin C, a natural compound derived from Brazilian green propolis, are likely related to its partition in the lipid bilayer component of biological membranes. ...
Functional transplantation of chloride channels from the human syncytiotrophoblast microvillous membrane to Xenopus oocytes
(2002)
The materno-fetal transfer of metabolites and nutrients requires the operation of specific transport mechanisms through syncytiotrophoblast membranes. Electrophysiological studies on these cells are scarce and, because of ...
P-Glycoprotein contributes to cell membrane depolarization of hippocampus and neocortex in a model of repetitive seizures induced by pentylenetetrazole in rats
(Bentham Science Publishers, 2013-03)
P-glycoprotein (P-gp) has been associated with pharmacoresistance and mechanisms regulating the membrane potential. However, at present it is unknown if P-gp overexpression in brain is associated with changes in membrane ...
