The influence of naphthenic acids and their fractions onto cell membrane permeability [PDF]

Journal of the Serbian Chemical Society, 2015
The influence of naphthenic acids (NAs) mixture and their narrow fractions (called NA pH 4, pH 8 and pH 10) onto permeability of beetroot cell membrane is examined.

Reverse Osmosis Membrane Cleaning Optimization from Textile Dyeing Wastewater Reuse Applications

Membranes
Reverse osmosis (RO) is the key process for textile dyeing wastewater reuse applications. Membrane fouling reduces both permeability and rejection capability, negatively affecting the technological economy of RO process.

Analysis of Antimicrobial-Triggered Membrane Depolarisation Using Voltage Sensitive Dyes

Frontiers in Cell and Developmental Biology, 2016
The bacterial cytoplasmic membrane is a major inhibitory target for antimicrobial compounds. Commonly, although not exclusively, these compounds unfold their antimicrobial activity by disrupting the essential barrier function of the cell membrane.

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 ...

Forward Osmosis (FO) Membrane Fouling Mitigation during the Concentration of Cows’ Urine

Membranes, 2022
FO membrane fouling mitigation during the concentration of cows’ urine was investigated. In particular, the effects on the permeability recovery of cleaning methods such as membrane washing with deionized (DI) water, osmotic backwash, and chemical ...

Integrin-mediated membrane blebbing is dependent on the NHE1 and NCX1 activities. [PDF]

, 2011
Integrin-mediated signal transduction and membrane blebbing have been well studied to modulate cell adhesion, spreading and migration^1-6^. However, the relationship between membrane blebbing and integrin signaling has not been explored.

Membrane thickness, lipid phase and sterol type are determining factors in the permeability of membranes to small solutes

Nature Communications, 2022
Membrane permeability of small molecules depends on the composition of the lipid bilayer. Here, authors compare permeability measured on membranes in different physical states and conclude that the yeast membrane exists in a highly ordered phase.
