Optical Control of Therapeutic Synthetic Cells: Controlling Biomolecule Synthesis, Activation, and Communication

Small Methods, EarlyView.
Combining synthetic cells engineering, cell‐free expression, and optical regulation may enable a new generation of programmable synthetic cell platforms. By providing spatiotemporal control over biomolecule synthesis, activation, transport, release, and communication, light offers a versatile strategy for coordinating proteins, RNAs, peptides, and ...

TorchRef: an open‐source PyTorch framework for crystallographic refinement

Journal of Applied Crystallography, EarlyView.
TorchRef is an open‐source PyTorch‐based crystallographic refinement framework that exposes all refinable parameters to automatic differentiation, accelerates structure factor evaluation by about two orders of magnitude on a GPU and enables novel workflows such as direct refinement against amplitude differences in time‐resolved crystallography ...

Rate-equation theory of azobenzene monolayer photoisomerization

, 1999
We perform a rate-equation description of the photoisomerization of an azobenzene monolayer, and find that the corresponding displacement current consists of two exponential-decay components. This result depicts the existing experimental results well. (C)

A versatile on‐axis visualization system for the macromolecular crystallography beamline BM07 at the ESRF

Journal of Synchrotron Radiation, EarlyView.
A compact on‐axis microscope installed on the endstation of the macromolecular crystallography beamline BM07 at the ESRF is described. The system combines dual‐magnification on‐axis sample visualization with on‐axis laser injection and fluorescence measurements in back‐scattering geometry.

Advances in organic UV filters for sunscreens over the past decade

Photochemistry and Photobiology, EarlyView.
Highlighted organic UV filter frameworks that have been described for sunscreens over the past decade divided into three groups: derivatives of or inspired by approved organic UV filters, natural product‐based compounds, and miscellaneous. Abstract Ultraviolet (UV) radiation is a major environmental factor in photoaging, erythema, and skin cancer ...

Cis‐urocanic acid formation following far‐UVC exposure and associated signaling responses in keratinocytes

Photochemistry and Photobiology, EarlyView.
Far‐UVC (200–235 nm) has emerged as a safe and effective indoor disinfection tool, but effects on skin immunomodulation remain unclear. This study demonstrates that 222 nm far‐UVC converts trans‐urocanic acid (UCA) to its biologically active cis isomer at levels comparable with solar radiation. In keratinocytes, far‐UVC alone caused modest increases in

Development of chalcones structure‐related to avobenzone: Photoprotection, photostability, and safety evaluation

Photochemistry and Photobiology, EarlyView.
Scaffold hopping strategy used to develop chalcones structure‐related to the avobenzone tautomer. Positive aspects of 2‐hydroxychalcones are highlighted. Abstract Chalcones are α,β‐unsaturated ketones with extended π‐conjugation, making them promising scaffolds for the development of organic UV filters.
