Synthetic polymer nanocarrier enhances dsRNA stability but not RNAi efficacy in Brassicogethes aeneus

Pest Management Science, EarlyView.
Experimental setup for dsRNA feeding in Brassicogethes aeneus to evaluate the effect of a synthetic polymer nanocarrier on RNAi efficiency. The experiment assessed whether the nanocarrier enhances RNAi after oral dsRNA delivery. (a) Stability of dsRNA–nanocarrier complexes was tested in simulated gut conditions. (b) Gene expression of αCOP and dre4 was

Exploring the Fragmentation of Sodiated Species Involving Covalent‐Bond Cleavages for Metabolite Characterization

Rapid Communications in Mass Spectrometry, EarlyView.
ABSTRACT Rationale Electrospray (ESI), the most popular desorption/ionization technique used in mass spectrometry‐based metabolomics, generates both protonated and deprotonated molecules, as well as adduct ions, sodium being the most frequent monoatomic cation entering their composition.

Impact of Positively Charged Backbone Modifications on the Properties of Spherical Nucleic Acids

Small, EarlyView.
A synthesis of spherical nucleic acids (SNAs) featuring cationic backbone modifications is presented, together with an analysis of their emerging properties. Introducing positively charged guanidinium groups near the SNA surface enhances cellular uptake and offers a pathway toward more precise control over SNA internalization.

Symmetry‐Guided Optical Control of Dynamic 1D Protein Self‐Assembly and Precise In Vitro Initiation of Biomolecular Condensation

Small, EarlyView.
A photoreversible 1D protein assembly has been developed by utilizing symmetry matching between StrepTactin and photoswitchable Dronpa145N. The light‐induced modulation of oligomerization allows for precise control over protein connectivity and valency.

Peptide‐directed nanovehicles enabling tumor‐selective ROS amplification and antitumor immunity

VIEW, EarlyView.
Cancer cells are vulnerable to oxidative stress, yet exploit immune tolerance to escape destruction. In contrast, their metabolic profile is markedly altered to support rapid proliferation, accompanied by elevated production of reactive oxygen species (ROS).

Polyaniline as a dual flame retardant and electrostatic dissipative additive in polyethylene nanocomposites

Journal of Vinyl and Additive Technology, Volume 31, Issue 2, Page 339-355, March 2025.
Effecft of co‐doping polyaniline with phosphoric acid and phytic acid on the heat release rate of polyethylene. Abstract Polyolefins, such as polyethylene (PE), are highly flammable and electrically insulative, limiting their applicability. The study explored the flame‐retardancy and electrical conductivity of PE/polyaniline (PE/PANI) nanocomposites ...

Stimulating proteasomal degradation in human proteinopathies

The FEBS Journal, EarlyView.
The proteasome mediates the degradation of a wide range of proteins. Boosting proteasomal degradation may be beneficial in several disease contexts and can be achieved either by modulating proteasome activity or by improving substrate delivery. Proteasome activity can be enhanced by increasing proteasome abundance, inducing constitutive gate opening ...

Mapping of C5‐Blocking Monoclonal Antibodies Reveals New C5 Inhibitory Epitopes and Novel Modes of C5 Inhibition

Immunology, EarlyView.
We identify four distinct C5 inhibitory epitopes, including two novel antibodies that selectively block membrane attack complex (MAC) assembly while preserving C5 cleavage and C5a generation. These findings establish selective MAC inhibition as a new therapeutic strategy for complement‐mediated diseases.
