CO2 Laser Ablation Area Scaling and Redeposition on Flat Polyoxymethylene Targets

open access: yes, 2010
One of the remaining subjects of interest for laser ablation propulsion study is whether special benefits or challenges exist when applying a particularly large or small laser spot area to a target. This subject is of high importance for topics including

Modulation of Homer1 EVH1 domain internal dynamics by putative autism‐associated mutations

open access: yesFEBS Letters, EarlyView.
The putative autism‐associated M65I and S97L variants of the EVH1 domain of the postsynaptic scaffold protein Homer1 do not exhibit substantial changes in their overall structure or partner binding. Both of them, but especially the M65I variant, show altered internal dynamics relative to the wild‐type domain on the μs‐ms timescale, indicated by the ...

(Ti,Zr,Hf,Ta)CN/SiCN: A new ultrahigh-temperature ceramic nanocomposite with excellent mechanical properties and ablation resistance

open access: yesJournal of Advanced Ceramics
Dense monolithic (Ti,Zr,Hf,Ta)CN/SiCN ceramic nanocomposites are prepared via the pyrolysis of novel (Ti-,Zr-,Hf-,Ta)-containing single-source precursors (SSPs) and spark plasma sintering (SPS) with a high heating rate.

An unexpected alternative viologen electron mediator site in tungsten‐containing formate dehydrogenase

open access: yesFEBS Letters, EarlyView.
An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

Epicardial Electrical Activation During Atrial Fibrillation

open access: yesJACC: Case Reports, 2019
High-definition mapping of atrial fibrillation is most commonly performed from the endocardial surface. This report describes an example of a case in which combined mapping of the endocardium and epicardium of the left atrium demonstrated electrical ...

Radiofrequency thermal ablation of renal graft neoplasms: A literature review

open access: yes, 2019
Neoplasms occurring in renal grafts represent a relatively novel and rare condition, whose treatment has not been standardized yet. Radiofrequency thermal ablation (RFA) of renal graft neoplasms is a nephron-sparing treatment, reported to be safe and ...

Cell geometry and membrane protein crowding constrain Escherichia coli growth rate, overflow metabolism, respiration, and maintenance energy

open access: yesFEBS Letters, EarlyView.
The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This

Evidence-based robust design of deflection actions for near Earth objects

open access: yes, 2012
This paper presents a novel approach to the robust design of deflection actions for Near Earth Objects (NEO). In particular, the case of deflection by means of Solar-pumped Laser ablation is studied here in detail. The basic idea behind Laser ablation is

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

open access: yesFEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Efficacy and safety of atrial fibrillation ablation in patients aged ≥80 years: a retrospective study [PDF]

open access: yes
Catheter ablation is the first-line treatment for atrial fibrillation. Although the efficacy and safety of this procedure have been reported in older patients, they might diminish with age.
