The Influence of Moderate Electroporation on E. coli Membrane Permeability

Microorganisms
This study examined the membrane permeability of E. coli, which were exposed to a moderate pulsed electric field (PEF) (3.3 kV/cm). The membrane permeability of E. coli was examined as a function of time after exposure to PEF.

Structure‐forward targeting of claudins with synthetic binders

FEBS Letters, EarlyView.
Claudins form the paracellular barriers between epithelial and endothelial tissues at tight junctions and are targets for molecular binders with the goal of modulating barrier permeability. Claudin‐binding molecules are relevant in drug delivery or in altering claudin interactions with disease‐causing proteins.

In-situ rapid construction of aliphatic amine combined polyamide seawater reverse osmosis membrane for efficient boron removal

, 2023
Polyamide (PA) reverse osmosis membranes are commonly employed in seawater desalination owing to their effective salt rejection and water permeability; however, the elimination of small and neutral boron molecules from seawater remains a significant ...

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.

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 ...

Permeability and topography of membranes

Chemistry and Physics of Lipids, 1972
In this brief review, we will report that the permeability of both artificial and natural membranes depends at least on the following lipid parameters: (1) The nature of the hydrocarbon chains of phospholipids. Because of a less compact packing of unsaturated phospholipids when compared with saturated ones, the former barrier will be more permeable ...

Engineering peptides into antibodies—opportunities and strategies for therapeutic innovation

FEBS Letters, EarlyView.
Peptides and antibodies occupy complementary therapeutic niches. Peptides recognize difficult targets in a compact format, while antibodies add specificity, long half‐life, and effector functions. This review examines strategies that merge both modalities—peptide grafting into loops, terminal and Fc fusions, and bioconjugation—highlighting how ...

Autophagy and mitophagy in pancreatic β‐cell homeostasis and their involvement in diabetes pathophysiology

FEBS Letters, EarlyView.
This review focuses on the role of autophagy and mitophagy in maintaining pancreatic β‐cell function and homeostasis. We discuss how genetic defects affecting these pathways contribute to the development of type 1, type 2, monogenic, and gestational diabetes. We further explore their potential as therapeutic targets. Created in BioRender.
