Toward Personalized Theranostics: A Modular PET Platform for Antibody‐Based Imaging and Therapy

Advanced Science, EarlyView.
This modular, site‐specific antibody platform enables customizable conjugates for PET imaging and therapy. Interchangeable payloads – including radiometals, cytotoxics, and fluorophores – support adaptable, multimodal applications with limited off‐target effects. In vivo, the DFO/DOTAGA bischelate immunoconjugate provided clear tumor delineation in PET/

Liquid chromatography coupled to mass spectrometry for steroid hormones analysis: issues and solutions in sample preparation and method development

Journal of Chromatography Open
Current work presents main aspects of the application of liquid chromatography in combination with low- and high-resolution mass spectrometry to an analysis of steroid hormones. Advantages and challenges of both targeted and untargeted analysis are shown

A Novel tRNA Half mt‐5’‐tiRNA‐Tyr Promotes Colorectal Cancer Proliferation via Inducing HARS2 Succinylation

Advanced Science, EarlyView.
A mitochondria‐derived tRNA half, mt‐5’‐tiRNA‐Tyr, is upregulated in colorectal cancer tissues and plasma and promotes tumor proliferation. It binds HARS2 and promotes CPT1A‐associated HARS2 K91 succinylation, disrupts HARS2–mt‐tRNA‐His association, impairs mitochondrial translation, enhances succinate‐linked metabolic reprogramming, and shows promise ...

Imaging mass spectrometry of polymeric materials [PDF]

, 2009
Imaging mass spectrometry (MS) is a technique that makes images of molecular distributions at surfaces based on mass spectral information. At a range (typically a raster) of positions, mass spectra are measured from the surface giving a characteristic ...

Stabilising the Lattice Oxygen Oxidation Mechanism Through Iridium Single Atoms in Chromium‐Doped Cobalt Iron Layered Double Hydroxides

Advanced Science, EarlyView.
Iridium single atoms and Cr doping synergistically activate and stabilise the lattice oxygen oxidation mechanism in CoFe layered double hydroxides. Electronic modulation enhances metal–oxygen covalency, suppresses over‐oxidation, and enables durable oxygen evolution, delivering high‐performance anion exchange membrane water electrolysis with ...

Investigations of the Evolved Molecular Basis for Terpenoid Biosynthesis in Marine Sponges

Advanced Science, EarlyView.
Confirming and extending a previous observation in another Bubarida sponge, genomic and functional analyses of A. cavernosa reveal that sponges retain the mevalonate pathway and employ single α‐domain T1TSs and UbiA‐type TSs for terpenoid biosynthesis. The absence of T1TSs clustering with other biosynthetic genes tentatively suggests, based on limited ...
