Carbon dots: An innovative luminescent nanomaterial
Aggregate, 2022 In recent years, carbon dots (CDs), including carbon nanodots, carbonized polymer dots, carbon quantum dots, and graphene quantum dots have attracted a mounting interest as readily accessible, nontoxic, and relatively inexpensive carbon‐based ...

Unexpectedly fast transfer of positron-emittable artificial substrate into N-terminus of peptide/protein mediated by wild-type L/F-tRNA-protein transferase [PDF]
, 2015 This article demonstrates the fastest enzymatic introduction of a positron emission tomography (PET) probe into acceptor peptides/proteins. It is site-specifically introduced at the basic N-terminus of the acceptors by using L/F-transferase in ...

Advanced Science, EarlyView.This study investigates the integrated diagnostic and therapeutic strategy utilizing 89Zr/131I‐labeled tinurilimab for the management of malignant lung nodules, with a particular focus on lung adenocarcinoma (LUAD). CEACAM6, which is highly expressed in most LUAD patients, activates the Src/FAK signaling pathway, thereby promoting cell proliferation ...

Radiopharmaceutical Therapy [PDF]
Health Physics, 2019 Abstract Radiopharmaceutical therapy involves the use of radionuclides that are either conjugated to tumor-targeting agents (e.g., nanoscale constructs, antibodies, peptides, and small molecules) or that concentrate in tumors through natural physiological mechanisms that occur predominantly in neoplastic cells.

A projection-domain low-count quantitative SPECT method for alpha-particle emitting radiopharmaceutical therapy [PDF]
arXiv, 2021 Single-photon emission computed tomography (SPECT) provides a mechanism to estimate regional isotope uptake in lesions and at-risk organs after administration of {\alpha}-particle-emitting radiopharmaceutical therapies ({\alpha}-RPTs). However, this estimation task is challenging due to the complex emission spectra, the very low number of detected ...

Visualization of the Spiral Ganglion Neuron in Vivo Using a Novel 177Lu Nuclear Molecule Label
Advanced Science, EarlyView.The study developed and validated a radionuclide‐labeled anti‐VGLUT1 antibody probe for the first nuclear imaging of cochlear spiral ganglion neurons (SGNs) in vivo. This approach may provide aid in screening candidates suitable for CI surgery by quantifying the number of surviving SGNs, and predicting the potential for postoperative hearing ...

Evaluation of imaging protocol for ECT based on CS image reconstruction algorithm [PDF]
, 2013 SPECT (Single-photon Emission Computerized Tomography) and PET (Positron Emission Tomography) are essential medical imaging tools, for which the sampling angle number, scan time should be chosen carefully to compromise between image quality and the radiopharmaceutical dose.
