Synergistic perspectives—How single‐molecule biophysics complement biochemical understanding

open access: yesFEBS Letters, EarlyView.
In this review, we discuss how ensemble biochemistry and single‐molecule approaches are complementary, outline commonly used single‐molecule techniques, and illustrate their relevance through two representative case studies: chromatin organization by SMC complexes and pathway choice during DNA double‐strand break repair.

Fabrication, Microstructural Characterization, and Ablation Behavior of a Novel 3D Orthogonal Woven C/C-SiC-ZrB2 Composite Through I-CVI, SI, and LSI Combined Processes [PDF]

open access: yesIranian Journal of Materials Science and Engineering
This paper presents the novel fabrication method of a three-dimensional orthogonally woven (3DW) C/C-SiC-ZrB2 composite and the effects of ZrB2 and SiC particles on microstructure and the ablation behavior of the C/C–SiC–ZrB2 composite are studied.

Ablation Properties of HfC–SiC–WC Ultra‐High Temperature Ceramics Produced by Pressureless Sintering

open access: yesInternational Journal of Ceramic Engineering & Science
HfC–SiC is one of the leading thermal insulation ceramics that has the potential to perform well under high thermomechanical loads. In this study, we explore the use of pressureless sintering to produce this material at relatively low temperatures (2100 ...

Microstructure and ablation properties of C/C-Zr-Si-O composites prepared by carbothermal reduction of hydrothermal co-deposited oxides

open access: yesMaterials & Design, 2018
C/C-Zr-Si-O composites were prepared by carbothermal reduction of hydrothermal co-deposited ZrO2, SiO2, and C. The bulk density of composites reached 1.71 g/cm3 with 8 cycles of co-deposition.

From junk to function — How weak selection in eukaryotes builds new parts and drives genomic complexity

open access: yesFEBS Letters, EarlyView.
How do genomes gain new functional parts? In eukaryotes, which tend to evolve under weak selection, much of the genome is junk. Palazzo and Qiu borrow the logic of Markov chains to show how non‐functional DNA becomes functional through the appearance of intermediate states, which arise due to epistasis, buffering, and biochemical messiness, allowing ...

The Shewanella oneidensis Fic enzyme SoFic targets the switch‐I region of EF‐Tu for AMPylation

open access: yesFEBS Letters, EarlyView.
Fic enzymes mediate diverse post‐translational modifications across all domains of life, including AMPylation. Prokaryotic EF‐Tu can be AMPylated and deAMPylated by the conserved Fic enzyme SoFic. Structural and biochemical approaches were used to characterize the effect of AMPylation on EF‐Tu, SoFic's enzymatic activities, and the enzyme‐target ...

Catheter ablation of drug resistant supraventricular tachycardia in neonates and infants

open access: yesCardiology Journal, 2013
The aim of this study was to evaluate the indications, results and complications of radiofrequency ablation (RFA) and transcatheter cryoablation (TCA) in neonates and infants with incessant drug-resistant supraventricular tachycardia (SVT).Out of 225 patients who underwent RFA and TCA at our center between January2010 and February 2012, 5 patients ...
