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

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.

Autophagic cell death is dependent on lysosomal membrane permeability through Bax and Bak

eLife, 2017
Cells deficient in the pro-death Bcl-2 family members Bax and Bak are known to be resistant to apoptotic cell death, and previous we have shown that these two effectors are also needed for mitochondrial-dependent cellular necrosis (Karch et al., 2013 ...

Phase transitions in biological membranes [PDF]

Book chapter in: C. Demetzos and N. Pippa (eds.), Thermodynamics and Biophysics of Biomedical Nanosystems, Series in BioEngineering, Springer Nature Singapore 2019, 2018
Native membranes of biological cells display melting transitions of their lipids at a temperature of 10-20 degrees below body temperature. Such transitions can be observed in various bacterial cells, in nerves, in cancer cells, but also in lung surfactant.

Topical Delivery of Cell-Penetrating Peptide-Modified Human Growth Hormone for Enhanced Wound Healing

Pharmaceuticals, 2023
Protein drugs have been emerging as a class of promising therapeutics. However, their topical application has been limited by their high molecular weight and poor permeability to the cell membrane. In this study, we aimed to enhance human growth hormone (

Capsid protein VP4 of human rhinovirus induces membrane permeability by the formation of a size-selective multimeric pore.

PLoS Pathogens, 2014
Non-enveloped viruses must deliver their viral genome across a cell membrane without the advantage of membrane fusion. The mechanisms used to achieve this remain poorly understood. Human rhinovirus, a frequent cause of the common cold, is a non-enveloped

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.

Creeping flow of micropolar fluid through a swarm of cylindrical cells with porous layer (membrane) [PDF]

Journal of Molecular Liquids Volume 294, 15 November 2019, 111558, 2019
The flow of micropolar fluid through a membrane modeled as a swarm of solid cylindrical particles with porous layer using the cell model technique is considered. The flow is directed perpendicular to the axis of the cylinders. Boundary value problem involves traditional conditions of velocities and stresses continuity, no-stress and no-couple stress ...

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 ...
