Polymers Pushing Polymers: Polymer Mixtures in Thermodynamic Equilibrium with a Pore [PDF]

Biophysical Journal, 2012
We investigate polymer partitioning from polymer mixtures into nanometer size cavities by formulating an equation of state for a binary polymer mixture assuming that only one (smaller) of the two polymer components can penetrate the cavity. Deriving the partitioning equilibrium equations and solving them numerically allows us to introduce the concept ...

Controllable gelation of artificial extracellular matrix for altering mass transport and improving cancer therapies

Nature Communications, 2020
The extracellular matrix (ECM) can influence tumor growth and its response to therapy. Here, the authors develop a fibrinogen and thrombin based artificial ECM that can starve tumours and prevent dissemination of cancer cells.

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

FEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

Electrospun Materials Based on Cellulose Acetate Loaded with Rosmarinic Acid with Antioxidant and Antifungal Properties

Biomimetics
Fibrous cellulose acetate (CA) materials loaded with rosmarinic acid (RA) were successfully created by one-pot electrospinning. In order to improve the water solubility of the polyphenolic acid and to facilitate its release from the fibrous materials ...
