An Enzymatic Platform for Late-Stage (Radio)isotope Labelling of Oligonucleotides With Methyltransferases. [PDF]

Angew Chem Int Ed Engl
State‐of‐the‐art synthesis of radiolabelled oligonucleotides involves multi‐step synthesis with high costs, extended timelines and significant radioactive waste generation. Herein, a dual‐methyltransferase platform enables late‐stage, site‐specific labelling, overcoming these limitations through reduced costs, faster turnaround and minimal radioactive ...

Distinct Foliar Uptake Pathways for Phosphorus and Nano-Hydroxyapatite in Potato Revealed By Synchrotron μCT and ³³P Imaging. [PDF]

Plant Cell Environ
ABSTRACT Potato (Solanum tuberosum L.) has a high phosphorus (P) requirement, yet its shallow root system and the strong P‐fixing capacity of many soils limit the effectiveness of soil fertilisation. Foliar application of nano‐hydroxyapatite particles (nHAPs) has emerged as a promising alternative P fertilisation practice.

Water‐Dispersible Ruthenium Nanocatalyst for Carbonyl Reduction With D2 or T2 in Aqueous Media

Angewandte Chemie, Volume 138, Issue 38, 14 September 2026.
We report the synthesis and characterization of water‐dispersible ruthenium nanoparticles that catalyze the reductive deuteration and tritiation of carbonyl compounds in aqueous media, enabling efficient access to a broad range of isotopically labeled polar molecules, including cyclic peptides, antibody‐drug conjugate linkers, pegylated derivatives ...

Hydroxyapatite (Ha) labeling with a phosphorus-32 radioisotope of the TRIGA 2000 reactor irradiation result as a candidate for radiosinovectomy therapy

Journal of Physics: Conference Series, 2020
Abstract Radiosynovectomy is a therapy performed on patients with acute-level arthritis (rheumatoid arthritis) as an alternative solution besides surgery. Radiosynovectomy is performed using a labeled compound with a particle size of 0.5-10 μm labeled with a β radioisotope.

Effects of benthic algae on release of soluble reactive phosphorus from sediments: a radioisotope tracing study

Water Science and Engineering, 2015
AbstractTo evaluate the effect of benthic algae on soluble reactive phosphorus (SRP) release from sediments in shallow lakes, experiments on SRP release with and without benthic algae in sediment cores and an experiment on SRP uptake by benthic algae were conducted using the radioisotope (32P) tracing method.

Coastal sediments record decades of cultural eutrophication in Tampa Bay, Florida, USA

Ecological Indicators
Phosphorus (P) sustainability is a complex problem – it is a limited resource critical for agricultural productivity, but fertilizer production generates extensive phosphogypsum waste and can impair downstream water quality.

Intercomparison of carbon‐13 and carbon‐14 tracer approaches for estimating marine calcification and net primary production

Limnology and Oceanography: Methods, EarlyView.
Abstract Accurate measurements of phytoplankton net primary production (NPP) and calcification are essential for quantifying marine carbon cycling, yet in situ calcification rates remain poorly constrained. We compared 13C‐ and 14C‐based tracer methods for NPP in laboratory cultures of the diatom Chaetoceros tenuissimus and the coccolithophore ...

Evaluation of Effects of Phosphorus Concentration on Microbial Population and Material Flux in Aquatic Microcosm Using Radioisotope Tracer

Japanese Journal of Water Treatment Biology, 2003
In this study, effects of phosphorus concentration on aquatic microcosms were evaluated in terms of microbial population dynamics and the photosynthetic activity that is the starting point of the material flux. Microcosms that consist of algae Chlorella vulgaris, bacteria Pseudomonas putida and ciliate Cyclidium glaucoma were incubated using media that

Metal Ions in Longgu (Fossilized Bone) as a Natural Synergistic Network for Multi‐Target Therapy in Psychiatric Disorders

Chemistry &Biodiversity, Volume 23, Issue 9, September 2026.
Longgu (fossilized bone) delivers a natural synergistic network of metal ions, Ca2+, Mg2+, Zn2+, Fe, Cu, and Mn2+ that collectively targets the interconnected pathologies of anxiety, depression, and insomnia. This multi‐ion system operates through coordinated mechanisms including ionostatic balance, cross‐pathway synergy, and systemic integration ...
