Systematic derivation of a surface polarization model for planar perovskite solar cells [PDF]

open access: yes, 2017
Increasing evidence suggests that the presence of mobile ions in perovskite solar cells can cause a current-voltage curve hysteresis. Steady state and transient current-voltage characteristics of a planar metal halide CH$_3$NH$_3$PbI$_3$ perovskite solar

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?

open access: yesFEBS Letters, EarlyView.
This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

EQCM and EIS Study of the Effect of Potential of Zero Charge on Escherichia Coli Biofilm Development

open access: yesInternational Journal of Electrochemical Science, 2010
Using EQCM method, the influence of electrode potential on Escherichia coli (E. coli) biofilm development was investigated in a range from −0.6V to 0.6V. Parabolic dependence of the cell density on the electrode potential was observed.

Disordered but rhythmic—the role of intrinsic protein disorder in eukaryotic circadian timing

open access: yesFEBS Letters, EarlyView.
Unstructured domains known as intrinsically disordered regions (IDRs) are present in nearly every part of the eukaryotic core circadian oscillator. IDRs enable many diverse inter‐ and intramolecular interactions that support clock function. IDR conformations are highly tunable by post‐translational modifications and environmental conditions, which ...

Nanoparticles-cell association predicted by protein corona fingerprints [PDF]

open access: yes, 2016
In a physiological environment (e.g., blood and interstitial fluids) nanoparticles (NPs) will bind proteins shaping a "protein corona" layer. The long-lived protein layer tightly bound to the NP surface is referred to as the hard corona (HC) and encodes ...

Substrate specificity of Burkholderia pseudomallei multidrug transporters is influenced by the hydrophilic patch in the substrate‐binding pocket

open access: yesFEBS Letters, EarlyView.
Multidrug transporters BpeB and BpeF from the Gram‐negative pathogen Burkholderia pseudomallei have a hydrophilic patch in their substrate‐binding pocket. Drug susceptibility tests and growth curve analyses using an Escherichia coli recombinant expression system revealed that the hydrophilic patches of BpeB and BpeF are involved in the substrate ...

Electrostatic Endothelial Cell Transplantation within Small-Diameter (<6 MM) Vascular Prostheses: A Prototype Apparatus and Procedure

open access: yesCell Transplantation, 1997
This article presents a novel, clinically relevant electrostatic endothelial cell transplantation (seeding/sodding) device (U.S. & Foreign Patent Protections Pending) for small-diameter (

Tumor acidity-induced charge-reversal liposomal doxorubicin with enhanced cancer cell uptake and anticancer activity

open access: yesGiant, 2021
Concerning that the polyethylene glycol surface layer of DOXIL hinders cancer cell uptake, thus leading to low anticancer activity, it is of great importance to promote the cancer cell uptake of liposomal doxorubicin.

Transition from ultrafast laser photo-electron emission to space charge limited current in a 1D gap

open access: yes, 2014
A one-dimensional (1D) model has been constructed to study the transition of the time-dependent ultrafast laser photo-electron emission from a flat metallic surface to the space charge limited (SCL) current, including the effect of non-equilibrium laser ...

Effects of paclitaxel nanocrystals surface charge on cell internalization

open access: yesEuropean Journal of Pharmaceutical Sciences, 2016
In this study, we investigated the influence of paclitaxel nanocrystals (PTX-NC) surface charge on cell internalization and cell cytotoxicity. PTX-NCs were prepared using the nano-precipitation method. The surface-modified PTX-NCs were prepared using an absorption method with positively charged poly(allylamine hydrochloride) (PAH) and negatively ...
