Heat Stress Dictates Microbial Lipid Composition along a Thermal Gradient in Marine Sediments

open access: yesFrontiers in Microbiology, 2017
Temperature exerts a first-order control on microbial populations, which constantly adjust the fluidity and permeability of their cell membrane lipids to minimize loss of energy by ion diffusion across the membrane.

Membrane stress increases cation permeability in red cells

open access: yesBiophysical Journal, 1994
The human red cell is known to increase its cation permeability when deformed by mechanical forces. Light-scattering measurements were used to quantitate the cell deformation, as ellipticity under shear. Permeability to sodium and potassium was not proportional to the cell deformation. An ellipticity of 0.75 was required to increase the permeability of

Clostridium perfringens Epsilon Toxin Induces a Rapid Change of Cell Membrane Permeability to Ions and Forms Channels in Artificial Lipid Bilayers*

open access: yesJournal of Biological Chemistry, 2001
Epsilon toxin is a potent toxin produced by Clostridium perfringens types B and D, which are responsible for a rapidly fatal enterotoxemia in animals. One of the main properties of epsilon toxin is the production of edema.

Robust Bio‐Textiles Via Mycelium‐Cellulose Interface Engineering

open access: yesAdvanced Functional Materials, EarlyView.
This work introduces a new class of sustainable textiles by growing mycelium, the root‐like structure of fungi, into cellulose‐based fabrics. This semi‐interpenetrating mycelium‐cellulose fiber network combines the strength and breathability of natural fibers with the water‐resistant and adhesive properties of mycelium, resulting in a robust, scalable,
