Clinical Outcomes of Repeated Corneal Crosslinking for Progressive Keratoconus After Failure of Primary Procedure; Safety and Efficacy at 12-Month Follow-Up

Ophthalmology and Therapy
Introduction This study aims to evaluate the efficacy and safety of repeated corneal cross-linking (CXL) in patients with progressive keratoconus who have undergone an unsuccessful primary epithelium-off (epi-off) CXL procedure. Additionally, it compares

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

FEBS 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 ...

RNA‐related functions of BRCA2 in transcription, replication, and genome stability

FEBS Letters, EarlyView.
Beyond its role in homologous recombination, BRCA2 regulates R‐loop homeostasis, DNA–RNA hybrid resolution, RNA polymerase II dynamics, and transcriptional activation. Disruption of any of these functions can contribute to genome instability, inflammatory signaling, and tumorigenesis. BRCA2 is a central tumor suppressor protein best known for its roles

Laser-Induced Photo-Cross-Linking of Cisplatin-Modified DNA to HMG-Domain Proteins^†

, 2016
Laser-induced photo-cross-linking was investigated for DNA, modified with cisplatin at specific sites, bound to structure-specific recognition domains of proteins in the high-mobility group (HMG) class.

Artificial molecular machines and motors—Design and control of nanoscale motion

FEBS Letters, EarlyView.
Molecules are constantly moving because of thermal fluctuations, but random motion alone cannot be exploited to perform directional tasks. Artificial molecular machines use chemical, electrical, or light energy to bias this motion. Molecular shuttles, rotary motors, and supramolecular pumps illustrate how nanoscale movement can be controlled and ...
