Cell membrane electroporation modeling: A multiphysics approach
(Elsevier Science Sa, 2018-12)
Electroporation-based techniques, i.e. techniques based on the perturbation of the cell membrane through the application of electric pulses, are widely used at present in medicine and biotechnology. However, the electric ...
Spin label EPR suggests the presence of cholesterol rich domains in cultured insect cell membranes
(Academic Press Inc Elsevier Science, 2018-11)
Different spin labels were incorporated to the membranes of cultured insect UFL-AG-286 cells in order to characterize their physical properties by Electron Paramagnetic Resonance spectroscopy (EPR). The spectrum of the ...
Interaction of a polyarginine peptide with membranes of different mechanical properties
(Multidisciplinary Digital Publishing Institute, 2019-10)
The membrane translocation efficiency of cell penetrating peptides (CPPs) has been largely studied, and poly-arginines have been highlighted as particularly active CPPs, especially upon negatively charged membranes. Here ...
Computational model for membrane transporters: Potential implications for cancer
(Frontiers Media, 2021-02-22)
To explain the increased transport of nutrients and metabolites and to control the movement of drug molecules through the transporters to the cancer cells, it is important to understand the exact mechanism of their structure ...
Impedance spectroscopy and membrane potential analysis of microfiltration membranes. The influence of surface fractality
(Pergamon-Elsevier Science Ltd, 2018-03)
In this work, the proper charge density of a microfiltration membrane has been determined by using two different methods. Firstly, the ionic transport of a KCl solution has been investigated by simultaneous measurements ...
Role of plasma membrane lipid composition on cellular homeostasis: learning from cell line models expressing fatty acid desaturases
(Oxford University Press, 2014-01)
Experimental evidence has suggested that plasma membrane (PM)-associated signaling and hence cell metabolism and viability depend on lipid composition and organization. The aim of the present work is to develop a cell model ...
GABAA receptor and cell membrane potential as functional endpoints in cultured neurons to evaluate chemicals for human acute toxicity
(Pergamon-Elsevier Science Ltd, 2010-02)
Toxicity risk assessment for chemical-induced human health hazards relies mainly on data obtained from animal experimentation, human studies and epidemiology. In vitro testing for acute toxicity based on cytotoxicity assays ...
Lipids, membranes, colloids and cells: A long view
(Elsevier Science, 2021-10)
This paper revisits long-standing ideas about biological membranes in the context of an equally long-standing, but hitherto largely unappreciated, perspective of the cell based on concepts derived from the physics and ...
Characterization of a new composite membrane for point of need paper-based micro-scale microbial fuel cell analytical devices
(Public Library of Science, 2019-09-30)
Microbial fuel cells (MFCs) can evolve in a viable technology if environmentally sound materials are developed and became available at low cost for these devices. This is especially important not only for the designing of ...
Modeling active cell movement with the Potts model
(Frontiers Research Foundation, 2018-06-20)
In the last decade, the cellular Potts model has been extensively used to model interacting cell systems at the tissue-level. However, in early applications of this model, cell movement was taken as a consequence of membrane ...
