Role of the fast kinetics of pyroglutamate-modified amyloid-β oligomers in membrane binding and membrane permeability. [PDF]

, 2014
Membrane permeability to ions and small molecules is believed to be a critical step in the pathology of Alzheimer's disease (AD). Interactions of oligomers formed by amyloid-β (Aβ) peptides with the plasma cell membrane are believed to play a fundamental

Impact of Low Intensity Millimeter-Waves on Cell Membrane Permeability [PDF]

, 2009
As the applications and commercial uses of millimeter- and submillimeter-waves grow, we should take a more detailed look at the impact this frequency range has on biological systems.

Role of protein kinase C in inhibition of renin release caused by vasoconstrictors [PDF]

, 1986
It was the aim of the present study to get insight into some of the intracellular mechanisms by which the vasoconstrictor hormones angiotensin II (ANG II), arginine vasopressin (AVP), and norepinephrine (NE) inhibit renin release from renal ...

The porin and the permeating antibiotic: A selective diffusion barrier in gram-negative bacteria [PDF]

, 2008
Gram-negative bacteria are responsible for a large proportion of antibiotic resistant bacterial diseases. These bacteria have a complex cell envelope that comprises an outer membrane and an inner membrane that delimit the periplasm.

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 ...

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
