Aminoglycoside-Induced Phosphatidylserine Externalization in Sensory Hair Cells Is Regionally Restricted, Rapid, and Reversible [PDF]

open access: yes, 2008
The aminophospholipid phosphatidylserine (PS) is normally restricted to the inner leaflet of the plasma membrane. During certain cellular processes, including apoptosis, PS translocates to the outer leaflet and can be labeled with externally applied ...

Peptide‐based ligand antagonists block a Vibrio cholerae adhesin

open access: yesFEBS Letters, EarlyView.
The structure of a peptide‐binding domain of the Vibrio cholerae adhesin FrhA was solved by X‐ray crystallography, revealing how the inhibitory peptide AGYTD binds tightly at its Ca2+‐coordinated pocket. Structure‐guided design incorporating D‐amino acids enhanced binding affinity, providing a foundation for developing anti‐adhesion therapeutics ...

Effects on ellipsometric parameters caused by heat treatment of silicon (111) surface [PDF]

open access: yes, 1977
Heating of a silicon single crystal introduces a surface roughness. Crystals are heated for periods of 45 sec in the temperature range from 560 to 1150°C.

Ultrasonic treatment with nickel electroplating combined with oxidation for developing γ-Al2O3 washcoat on Fe-Cr-Al substrate [PDF]

open access: yes, 2012
Fe-Cr-Al is used as metallic support for catalytic converter due to its high thermal conductivity, lower heat capacity, high temperature and mechanical shock resistance. γ-Al2O3 is the most widely used material as washcoat which embedded on metallic

Metallic clusters on a model surface: quantum versus geometric effects

open access: yes, 2011
We determine the structure and melting behavior of supported metallic clusters using an ab initio density-functional-based treatment of intracluster interactions and an approximate treatment of the surface as an idealized smooth plane yielding an ...

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 ...

Comprehensive evaluation of MWCNT/HAp and Cu-functionalized MWCNT/HAp coatings on Ti6Al4V implants: Enhancing surface characteristics and biocompatibility via plasma electrolytic oxidation

open access: yesJournal of Materials Research and Technology
This study investigates the evolving relationships and interactions between two distinct materials used in hard tissue implants: multi-walled carbon nanotubes (MWCNTs) and copper nanoparticles (Cu NPs).

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 ...

Fatigue strength improvement of Mg alloy AZ61 by double ultrasonic shot peening

open access: yesNihon Kikai Gakkai ronbunshu, 2016
Rotary bending fatigue tests using magnesium alloy AZ61 treated by double ultrasonic shot peening (USP) and peening under other conditions were performed to investigate the effect of shot peening (SP) on the fatigue behavior and to obtain high and stable
