The therapeutic opportunities and pitfalls of using iron ion chelators to treat neurodegenerative diseases

open access: yesFEBS Letters, EarlyView.
Although too much iron in the brain promotes neurodegeneration, iron ion chelators have had mixed effects in clinical trials. This review explains why; some chelators do not render the iron redox‐inactive (e.g., L1) whereas others do (e.g., desferrioxamine).

Multi‐port bidirectional isolated DC–DC resonance converter with constant phase current for application in bipolar DC microgrids

open access: yesIET Power Electronics
This paper proposes a new DC–DC bipolar resonance converter that combines a dual‐active‐bridge and a multi‐port resonance Buck‐Boost converter. This structure uses a resonance network between the input and output ports, which has the following advantages:

Raman‐based label‐free microscopic analysis of the pancreas in living zebrafish larvae

open access: yesFEBS Open Bio, EarlyView.
Forward stimulated Raman scattering (F‐SRS) and epi coherent anti‐Stokes Raman scattering (E‐CARS) allow label‐free discrimination of distinct subcellular structures in the pancreas of living zebrafish larvae. Given the straightforward applicability, we anticipate broad implementation of Raman microscopy in other organs and across various biomedical ...

Proposing a new rotating frame‐based method for dynamic modelling of resonant converters

open access: yesIET Power Electronics
Resonant converters are widely used in various industrial applications due to features such as wide input voltage range, high efficiency, and high‐power density. Mathematical modelling of these converters is crucial because they simultaneously exhibit AC

Optimizing photoactivation of PA‐mCherry for optical pooled CRISPR screens

open access: yesFEBS Open Bio, EarlyView.
Photoactivatable PA‐mCherry finds widespread use to optically tag individual cells. However, confocal 405 nm UV laser‐scanning (normal scan) is much less efficient than widefield UV illumination, limiting the use of PA‐mCherry on confocal instruments. We remedy this limitation by reporting that rapid and repeated confocal scanning with a low‐intensity,

A Novel Phase‐Shifted Modulation for Balancing Current Stress During Startup of High‐Power Full‐Bridge DC/DC Converters

open access: yesThe Journal of Engineering
Traditional duty‐cycle or phase‐shift modulation is inadequate for achieving a balanced current‐stress distribution during the startup of full‐bridge DC/DC converters. As converter power capacity increases, these limitations not only restrict the startup

Comparison of boost and LLC converter and active clamp isolated full-bridge boost converter for photovoltaic DC system

open access: yesThe Journal of Engineering, 2019
DC collection network offers an attractive alternative to AC network for photovoltaic, as it avoids the charging current issues and reduces the size and weight. Variable voltage gain DC/DC converters play an important role in DC collection network.

UiO‐66 metal–organic frameworks in biomedicine: From structural tunability to bioimaging, photodiagnostics, and photodynamic cancer therapy

open access: yesFEBS Open Bio, EarlyView.
UiO‐66(Zr) metal–organic frameworks are chemically stable, biocompatible, and highly tunable nanomaterials. Their modular structure enables controlled drug delivery, multimodal bioimaging, and light‐activated photodynamic therapy, supporting integrated diagnostic and therapeutic (theranostic) applications in cancer and biomedical research.
