A Low‐Power Radioisotope XRF Spectrometer for Detection of Light Elements on Planetary Missions

X-Ray Spectrometry, EarlyView.
ABSTRACT Current X‐ray spectrometers for in situ geochemical analysis on planetary missions typically rely either on X‐ray tubes, which demand electrical power and add mass and thermal complexity, or on alpha particle X‐ray spectrometers (APXS) that use rare 244Cm$$ {}^{244}\mathrm{Cm} $$ sources, and come with severe concerns on radiation safety and ...

Terbium-149 production: a focus on yield and quality improvement towards preclinical application

Scientific Reports
Terbium-149 (T1/2 = 4.1 h, Eα = 3.98 MeV (16.7%), 28 µm range in tissue) is a radionuclide with potential for targeted alpha therapy. Due to the negligible emission of α-emitting daughter nuclides, toxicity to healthy tissue may be reduced in comparison ...

The Central-European SentiMag study: Sentinel lymph node biopsy with superparamagnetic iron oxide (SPIO) vs. radioisotope

The Breast, 2014
Sentinel lymph node biopsy (SLNB) is the standard surgical procedure for the axilla in early node-negative breast cancer. To date, the "gold standard" to localize the sentinel lymph node (SLN) is the radiotracer (99m)Tc with or without blue dye. The aim of this study was to evaluate potential equivalency of the new SentiMag(®) technique in comparison ...

Optimization of Cyanocobalamin (Vitamin B₁₂) Sorption onto Mesoporous Superparamagnetic Iron Oxide Nanoparticles

Molecules
The techniques used to detect and quantify cyanocobalamin (vitamin B12) vary considerably in terms of detection sensitivity, from the most sensitive, based on radioisotopes and mass spectrometry (MS) with limits of detection (LOD) in fg mL−1, to ...

Absolute Bioavailability and Absorption, Distribution, Metabolism, and Excretion of [14C]Xevinapant, a Potent, Oral, Small‐Molecule IAP Inhibitor

Clinical Pharmacology in Drug Development, Volume 15, Issue 3, March 2026.
Abstract This Phase 1, open‐label, 2‐part, single‐dose study aimed to investigate the pharmacokinetics, metabolism, and excretion of xevinapant, a small molecule inhibitor of apoptosis proteins (IAPs), in healthy male subjects. Part 1 focused on determining the mass balance recovery, pharmacokinetics, and metabolic profile of [14C]xevinapant following ...

Radioisotopic Evidence of Immobilization of Iron in Azalea by Excess Calcium Bicarbonate1

Journal of the American Society for Horticultural Science, 1971
Abstract The redistribution of 59 Fe in azalea plants was followed after allowing root absorption of the isotope under favorable conditions. During the 12 weeks of redistribution, high lime (Ca(HCO 3 ) 2

Cystoscopic ICG‐Guided Sentinel Lymph Node Dissection in Robotic Radical Prostatectomy: A Prospective Study

The Prostate, Volume 86, Issue 4, Page 481-492, March 2026.
ABSTRACT Background To evaluate the diagnostic accuracy, procedural feasibility, and clinical outcomes of a novel cystoscopic‐guided indocyanine green (ICG) injection technique followed by fluorescence‐guided sentinel lymph node dissection (SLND) during robotic‐assisted radical prostatectomy (RaRP), hereafter referred to as CysICG‐SLND.
