Synchrony and Oscillatory Dynamics for a 2-D PDE-ODE Model of Diffusion-Sensing with Small Signaling Compartments [PDF]
arXiv, 2020 We analyze a class of cell-bulk coupled PDE-ODE models, motivated by quorum and diffusion sensing phenomena in microbial systems, that characterize communication between localized spatially segregated dynamically active signaling compartments that have a permeable boundary. Each cell secretes a signaling chemical into the bulk region at a constant rate

Human cell recovery after microwave irradiation [PDF]
arXiv, 2009 Cells of human buccal epithelium of 6 male donors were exposed to microwave radiation (frequency f=36,64 GHz, power density E = 10, 100, and 400 mcW/cm^2). Exposure time in all experiments was 10 seconds. Heterochromatin was stained by 2% orcein in 45 % acetic acid. The stainability of cells with trypan blue (0,5 %) and indigocarmine (5 mM) after 5 min

Dynamics of membrane lipid domains in neuronal cells differentiated in culture1
Journal of Lipid Research, 2003 Treatment with methyl-β-cyclodextrin (MCD) induced a time- and dose-dependent efflux of cholesterol, sphingolipids, and phosphatidylcholine (PC) from cerebellar neurons differentiated in culture. With a “mild” treatment, the loss of cell lipids induced a

Heat Stress Dictates Microbial Lipid Composition along a Thermal Gradient in Marine Sediments
Frontiers in Microbiology, 2017 Temperature exerts a first-order control on microbial populations, which constantly adjust the fluidity and permeability of their cell membrane lipids to minimize loss of energy by ion diffusion across the membrane.

The resting potential of nerve cells and the Na,K-pump [PDF]
arXiv, 2017 In this pedagogical paper a coherent explanation of the resting potential of nerve cells is given in terms of its determining factors. These are the currents of active transport of the ions to which the membrane is permeable, their membrane permeabilities and their concentrations in the extracellular fluid.
