Positron Emission Tomography Imaging of Bacterial Infections With an Enterobactin Analog to Monitor Treatment Efficacy With a Catechol Antibiotic

Angewandte Chemie, EarlyView.
Synopsis. The [68Ga]GaIII‐TREN‐CAM radiochelate selectively accumulates in Gram‐negative sites of infection and noninvasively monitors treatment response a siderophore antibiotic. ABSTRACT Positron emission tomography (PET) is an emerging tool under clinical investigation for the detection of bacterial infections.

Comparison of ²¹⁰Pb Age Models of Peat Cores Derived from the Arkhangelsk Region

Applied Sciences, 2023
Dating young peatlands using the 210Pb dating procedure is a challenging task. The traditional 210Pb age models assume an exponential decline in radioactivity in line with depth in the peat profile. Lead exhibits considerable migratory capacity in Arctic

Constraints on stellar yields and SNe from gamma-ray line observations

, 1999
Gamma-ray line observations provide a versatile tool for studies of nucleosynthesis processes and supernova physics. In particular, the observation of radioactive species in the interstellar medium probes recent nucleosynthesis activity on various time ...

Plant‐Produced Viral Nanoparticles Decorated with Nanobodies Against HER2 Improve Retention and Recruitment of Immune Cells in Solid Tumors

Advanced Healthcare Materials, EarlyView.
Potato virus X is a filamentous RNA plant virus that can be engineered into a molecular tool for cancer therapy. We produced genetically‐encoded virus‐derived nanoparticles decorated with nanobodies targeting cancer cell receptors, epidermal growth factor receptor (EGFR) and human epidermal growth factor 2 (HER2).

Imaging the Earth's Interior: the Angular Distribution of Terrestrial Neutrinos

, 2004
Decays of radionuclides throughout the Earth's interior produce geothermal heat, but also are a source of antineutrinos. The (angle-integrated) geoneutrino flux places an integral constraint on the terrestrial radionuclide distribution. In this paper, we

Mapping CSC‐Mediated Ovarian Cancer Chemoresistance via CXCR4‐PET to Guide Precision Cisplatin Re‐Sensitization Therapy

Advanced Science, EarlyView.
CXCR4 functions as a potential cancer stem cell‐associated marker linked to chemoresistance in ovarian cancer, and an inhibitor of CXCR4, AMD3100, can enhance the cytotoxic response to cisplatin. Based on these findings, [68Ga]Ga‐Pentixafor positron emission tomography enables selective visualization of CXCR4‐high ovarian cancer, while AMD3100 combined
