Antibacterial Mechanism of The Ehyl Acetate Extracts From Naked Oat Again Bacillus subtilis
Aceh International Journal of Science and Technology, 2015 The antibacterial mechanism of the ethyl acetate extracts from naked oat against Bacillus subtilis were studied in this paper based on assays such as cell wall alkaline phosphatase (AKP), permeability and integrity of cell membrane as well as electron ...

Adenovirus-dependent increase in cell membrane permeability.
Journal of Biological Chemistry, 1985 When KB cells were labeled with either 51Cr (1 microCi/ml) or [35S]methionine (5 microCi/ml) and treated with 10 micrograms/ml of adenovirus type 2 (Ad2) at pH 6.0 for 60 min at 37 degrees C, about 25% of the cell-associated 51Cr and 5% of the [35S]methionine were released into the medium.

On necessary and sufficient conditions for proto-cell stationary growth [PDF]
arXiv, 2014 We consider a generic proto-cell model consisting of any conservative chemical reaction network embedded within a membrane. The membrane results from the self-assembly of one of the chemical species (membrane precursor) and is semi-permeable to some other chemical species (nutrients) diffusing from an outside growth medium into the proto-cell.

Volume changes during active shape fluctuations in cells [PDF]
, 2015 Cells modify their volume in response to changes in osmotic pressure but it is usually assumed that other active shape variations do not involve significant volume fluctuations. Here we report experiments demonstrating that water transport in and out of the cell is needed for the formation of blebs, commonly observed protrusions in the plasma membrane ...

Dynamics of cell membrane permeability changes at supraphysiological temperatures
Biophysical Journal, 1995 A quantitative fluorescent microscopy system was developed to characterize, in real time, the effects of supraphysiological temperatures between 37 degrees and 70 degrees C on the plasma membrane of mouse 3T3 fibroblasts and isolated rat skeletal muscle cells.

Growth and membrane permeability of two submersed macrophytes in response to ammonium enrichment
Aquatic Biology, 2013 Increased ammonium (NH4+) concentrations are reported to be an important cause of decline in submersed macrophytes in eutrophic lakes. In this study, a subacute experiment was conducted to examine the effects of various NH4+ concentrations on growth and ...

Intestinal Cells-on-Chip for Permeability Studies
MicromachinesBackground: To accurately measure permeability of compounds in the intestine, there is a need for preclinical in vitro models that accurately represent the specificity, integrity and complexity of the human small intestinal barrier.
