An XPS study of the thermal degradation of polystyrene-clay nanocomposites [PDF]

open access: yes, 2002
X-ray photoelectron spectroscopy, XPS, has been used to examine several polystyrene-clay nanocomposites. The accumulation of oxygen, from the almuniosilicate, on the surface of the polymer was observed, along with the loss of carbon.

Dynamic energy budget approach to evaluate antibiotic effects on biofilms [PDF]

open access: yes, 2017
Quantifying the action of antibiotics on biofilms is essential to devise therapies against chronic infections. Biofilms are bacterial communities attached to moist surfaces, sheltered from external aggressions by a polymeric matrix.

Ro 31‐8220 suppresses bladder cancer progression via enhancing autophagy in vitro and in vivo

open access: yesFEBS Open Bio, EarlyView.
The pan‐protein kinase C inhibitor Ro‐31‐8220 demonstrates potent anti‐bladder cancer effects both in vitro and in vivo by suppressing migration/invasion, inducing apoptosis and crucially activating autophagy, where blocking autophagy with chloroquine reduces its cell‐killing efficacy, suggesting its promise as a novel therapeutic candidate requiring ...

Finding Transition Pathways on Manifolds [PDF]

open access: yes, 2014
We consider noise-induced transition paths in randomly perturbed dynami- cal systems on a smooth manifold. The classical Freidlin-Wentzell large devia- tion theory in Euclidean spaces is generalized and new forms of action functionals are derived in the ...

Structural and functional characterization of chitinase from carnivorous plant Drosera adelae

open access: yesFEBS Open Bio, EarlyView.
A class I chitinase from the carnivorous plant Drosera adelae was expressed and purified using a yeast system, revealing high enzymatic activity. Structural analyses of the catalytic and chitin‐binding domains identified key tyrosine residues involved in substrate binding, offering insights into the enzyme's adaptation for insect digestion.

Diffusion‐based size determination of solute particles: a method adapted for postsynaptic proteins

open access: yesFEBS Open Bio, EarlyView.
We present a diffusion‐based approach for measuring the size of macromolecules and their complexes, and demonstrate its use on postsynaptic proteins. The method requires fluorescein‐labelled protein samples, a microfluidic device that maintains laminar flow for said samples, a microscope recording the emitted fluorescent signals, and an analytic ...

Rethinking plastic waste: innovations in enzymatic breakdown of oil‐based polyesters and bioplastics

open access: yesFEBS Open Bio, EarlyView.
Plastic pollution remains a critical environmental challenge, and current mechanical and chemical recycling methods are insufficient to achieve a fully circular economy. This review highlights recent breakthroughs in the enzymatic depolymerization of both oil‐derived polyesters and bioplastics, including high‐throughput protein engineering, de novo ...
