Single‐molecule DNA flow‐stretch assays for high‐throughput DNA–protein interaction studies
FEBS Open Bio, EarlyView.We describe an optimised single‐molecule DNA flow‐stretch assay that visualises DNA–protein interactions in real time. Linear DNA fragments are tethered to a surface and stretched by buffer flow for fluorescence imaging. Using λ and φX174 DNA, this protocol enhances reproducibility and accessibility, providing a versatile approach for studying diverse ...

Control of the formation and amplification of pulse bursts in regenerative amplifiers
IET Control Theory & Applications, 2023 This paper presents control strategies to generate bursts of high‐intensity laser pulses with arbitrary envelope from regenerative amplifiers by suitably adjusting the energy of the injected seed pulses. To this end, existing and experimentally validated

A 20 W, Less-Than-1-kHz Linewidth Linearly Polarized All-Fiber Laser
Applied Sciences, 2018 We report a continuous-wave high-output power and narrow-linewidth all-fiber laser at 1550 nm with the master oscillator power amplifier (MOPA) configuration. An all-fiber distributed feedback seed laser was boosted by three cascaded fiber amplifiers. In

FEBS Open Bio, EarlyView.Repair of neuronal DNA damage in Alzheimer's disease by KCL‐286. (A) Amyloid‐β oligomers and plaques impair neuronal DNA repair pathways, leading to DNA double‐strand breaks and glial activation. (B) KCL‐286 activates RARβ/RXR signalling via retinoic acid response elements (RAREs), associated with increased BRCA1 expression, enhanced DNA repair and ...

Optical fibres, lasers, and amplifiers [PDF]
Endeavour, 1992 Initially, the only operation that could be performed in optical fibre communication was transmitting optical information from one point to another, necessitating complex auxiliary electronic circuitry. In recent years, however, a range of fibre components has been developed which promise to become as ubiquitous and indispensable as the transistor is ...
