Small interfering RNA: Discovery, pharmacology and clinical development—An introductory review

British Journal of Pharmacology, Volume 180, Issue 21, Page 2697-2720, November 2023., 2023
Abstract Post‐transcriptional gene silencing targets and degrades mRNA transcripts, silencing the expression of specific genes. RNA interference technology, using synthetic structurally well‐defined short double‐stranded RNA (small interfering RNA [siRNA]), has advanced rapidly in recent years.

CatMass: software for calculating optimal sample masses for X‐ray absorption spectroscopy experiments involving complex sample compositions

Journal of Synchrotron Radiation, Volume 30, Issue 5, Page 1023-1029, September 2023., 2023
CatMass is a new software for calculating the optimal sample mass of samples with complex compositions (e.g. a supported metal catalyst mixed with a diluent) for X‐ray absorption and X‐ray scattering experiments with supplemental results to guide experimental design and collection geometry.This paper presents software for calculating the optimal mass ...

Pushing the Boundaries of Structural Heterogeneity with the Lipid A of Marine Bacteria Cellulophaga

ChemBioChem, Volume 24, Issue 10, May 16, 2023., 2023
Lipopolysaccharide and its lipid A from marine bacteria are a chemical gold for the development of new adjuvants and immune therapeutics. Here we defined the structure of three marine Cellulophaga species and the TLR4 activation potential of their lipopolysaccharide.

Nanoparticles for vaccine and gene therapy: Overcoming the barriers to nucleic acid delivery

WIREs Nanomedicine and Nanobiotechnology, Volume 14, Issue 6, November/December 2022., 2022
There is significant potential to improve the delivery of nucleic acid theraputics by engineering smart, responsive and targeted nanoparticle delivery systems. Abstract Nucleic acid therapeutics can be used to control virtually every aspect of cell behavior and therefore have significant potential to treat genetic disorders, infectious diseases, and ...

Wiggler radiation at a low‐emittance storage ring and its usage for X‐ray absorption spectroscopy

Journal of Synchrotron Radiation, Volume 29, Issue 2, Page 462-469, March 2022., 2022
Experimental and computational studies of wigglers on low‐emittance storage rings are reported. EXAFS spectra for possible distortions originating from the source imperfection are also examined. It is concluded that wigglers are still an appropriate class of insertion devices, also on low‐emittance synchrotrons.A wiggler is a high‐power insertion ...

Dispersion‐compensated Rowland spectrometer: implications for uranium VB‐RIXS

Journal of Synchrotron Radiation, Volume 33, Issue 1, Page 218-226, January 2026.
A valence‐band resonant inelastic X‐ray scattering instrument, operating in the tender X‐ray range, uses an incoming beam with a linear energy dispersion to reach the intrinsic resolution of the Rowland spectrometer. Such a scheme is insensitive to the incident bandwidth and therefore preserves count‐rates despite the higher resolution.The total energy

Indiscernibles in monadically NIP theories

Bulletin of the London Mathematical Society, Volume 57, Issue 11, Page 3326-3345, November 2025.
Abstract We prove various results around indiscernibles in monadically NIP theories. First, we provide several characterizations of monadic NIP in terms of indiscernibles, mirroring previous characterizations in terms of the behavior of finite satisfiability. Second, we study (monadic) distality in hereditary classes and complete theories.

Narrow‐Linewidth Emission and Weak Exciton‐Phonon Coupling in 2D Layered Germanium Halide Perovskites

Advanced Materials, Volume 37, Issue 27, July 10, 2025.
The structural and photophysical properties of the 2D layered metal halides (4F‐PMA)2GeI4 and (4F‐PMA)2PbI4 are reported. For the Ge composition, reduced exciton‐phonon coupling is found and the absence of bound‐exciton emission, present for the Pb composition.

Groups with boundedly Černikov conjugacy classes

Advances in Group Theory and Applications, 2021
Summary: A relevant theorem of B. H. Neumann states that if a group \(G\) has boundedly finite conjugacy classes, then its commutator subgroup \(G'\) is finite. This result has been generalized in [\textit{E. Detomi} et al., Glasg. Math. J. 63, No. 1, 54--58 (2021; Zbl 1530.20084)], where it is proved in particular that if the orbits of a group \(G ...
