Mitochondrial membrane permeability transition and cell death

Biochimica et Biophysica Acta (BBA) - Bioenergetics, 2006
Mitochondria are important organelles for energy production, Ca2+ homeostasis, and cell death. In recent years, the role of the mitochondria in both apoptotic and necrotic cell death has received much attention. In apoptotic and necrotic death, an increase of mitochondrial membrane permeability is considered to be one of the key events, although the ...

Continuous wave irradiation at 0.1 terahertz facilitates transmembrane transport of small molecules

iScience, 2022
Summary: The bioeffects of terahertz (THz) radiation received growing attention because of its influence on the interactions between biomolecules. Our work aimed to investigate the effects of THz irradiation on cell membrane, especially cell membrane ...

Permeability of a Cell Membrane Junction [PDF]

The Journal of General Physiology, 1969
The ion permeability of the membrane junctions between Chironomus salivary gland cells is strongly depressed by treatments that are generally known to inhibit energy metabolism. These treatments include prolonged cooling at 6°–8°C, and exposure to dinitrophenol, cyanide, oligomycin, and N-ethylmaleimide.

Acetaminophen Changes Intestinal Epithelial Cell Membrane Properties, Subsequently Affecting Absorption Processes

Cellular Physiology and Biochemistry, 2013
Background/Aims: Acetaminophen (APAP) effects on intestinal barrier properties are less investigated. APAP may lead to a changed bioavailability of a subsequently administered drug or diet in the body. We investigated the influence of APAP on enterocytic

Lens Cell Membrane Permeability and Cataract Formation.

Experimental Biology and Medicine, 1964
SummaryAnalyses of rat lenses just before and just after the appearance of diabetic or galactose cataracts demonstrate that this event is accompanied by an abrupt disruption of the cell membranes of the lens. The concentrations of polyol, glucose and fructose in the lens approach those in the blood; and the extracellular space as determined with ...

Effect of proanthocyanidins on cell membrane properties of Saccharomyces cerevisiae [PDF]

Zhongguo niangzao
In order to investigate the action mechanism of proanthocyanidins from the perspective of cell membrane, the effects of 0.5 g/L and 1.0 g/L proanthocyanidins on the characteristics of the cell membrane of Saccharomyces cerevisiae were studied.

Determination of cell membrane permeability in concentrated cell ensembles

Biophysical Journal, 1987
The method of volume averaging is used to analyze the process of diffusion in concentrated cell ensembles in which significant resistance to mass transfer is caused by the cellular membrane. A general closure scheme is given that allows for direct theoretical prediction of effective diffusivities for any cellular geometry.
