One-step volumetric additive manufacturing of complex polymer structures. [PDF]

, 2017
Two limitations of additive manufacturing methods that arise from layer-based fabrication are slow speed and geometric constraints (which include poor surface quality). Both limitations are overcome in the work reported here, introducing a new volumetric

Matrix: a complex amalgam of structures and functions in tumor microenvironment

FEBS Open Bio, EarlyView.
The matrix is a dynamic, intricate three‐dimensional mesh of biomolecules with both structural and functional properties. This review deals with the complexity of this ‘molecular amalgam’ in the tumor microenvironment and highlights its importance in the maintenance and evolution of tumors by describing certain matrix biomolecules, such as ...

Electrochemical removal of phenol in alkaline solution. Contribution of the anodic polymerization on different electrode materials [PDF]

, 2009
The removal of organic pollutants based on electropolymerization on an anode was performed in the case of phenol in alkaline solution. The polymer formed by a process involving less than two electrons per molecule of phenol, is then precipitated by ...

Actin dynamics controlled by IqgC, a RasGAP at the crossroads between the IQGAP and fungal GAP1 families

FEBS Open Bio, EarlyView.
IqgC is a RasGAP from Dictyostelium discoideum. IqgC binds RasG via its RasGAP domain and deactivates it on macroendocytic cups, thereby suppressing the uptake of fluid and particles. IqgC has a positive effect on cell‐substratum adhesion, and its RGCt domain is required for recruitment to ventral foci.

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

FEBS 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 ...

Photoredox Catalysis for Polymerization Reactions

CHIMIA, 2012
Photoredox catalysis is now well-known in organic synthesis for the formation of free radicals under very soft irradiations conditions (e.g. sunlight, household fluorescence or LED bulbs, Xe lamp).

Structural and functional characterization of chitinase from carnivorous plant Drosera adelae

FEBS 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.
