Alpha-PET with terbium-149: evidence and perspectives for radiotheragnostics

EJNMMI Radiopharmacy and Chemistry, 2016
149Tb represents a powerful alternative to currently used α-emitters: the relatively short half-life (T1/2 = 4.1 h), low α-energy (3.97 MeV, Iα = 16.7 %), absence of α-emitting daughters and stable coordination via DOTA are favorable features for ...

[11C]mHED PET follows a two-tissue compartment model in mouse myocardium with norepinephrine transporter (NET)-dependent uptake, while [18F]LMI1195 uptake is NET-independent

EJNMMI Research, 2020
Purpose Clinical positron emission tomography (PET) imaging of the presynaptic norepinephrine transporter (NET) function provides valuable diagnostic information on sympathetic outflow and neuronal status.

RGD Forever!—Past, Present, and Future of a 3-Letter-Code in Radiopharmacy and Life Sciences

, 2022
“RGD” is frequently pictured as a ligand for αvβ3-integrin and useful for molecular targeting of angiogenesis—which is about as simplistic as the idea that laser beams are green or red and particularly useful for arming ...

Affinity‐Tuned Albumin Hitchhiking Extends the Bioorthogonal Capture Window in Pretargeting Radiotheranostics

Advanced Healthcare Materials, EarlyView.
Pharmacokinetic engineering of clickable radioligands was achieved via albumin hitchhiking approach within a pretargeted radiotheranostics delivery platform. This approach reduced rapid renal elimination, expanded bioorthogonal capture window, boosted tumor uptake by ∼3.5‐fold, and improved the tumor‐to‐liver ratio by ∼6‐fold.

44Sc for labeling of DOTA- and NODAGA-functionalized peptides: preclinical in vitro and in vivo investigations

EJNMMI Radiopharmacy and Chemistry, 2016
Background Recently, 44Sc (T1/2 = 3.97 h, Eβ+ av = 632 keV, I = 94.3 %) has emerged as an attractive radiometal candidate for PET imaging using DOTA-functionalized biomolecules.

Quantitative studies in radiopharmaceutical science

, 1989
The scientific direction of the work in this grant is unchanged and the 12 research projects in the three major categories represent only minor modification from the proposed work given at site visit. Adjustment was necessary in keeping with the award and to accommodate the resignation of Dr. S.

Molecular Imaging of Aortic Valve Stenosis with Positron Emission Tomography

, 2022
Aortic valve stenosis (AVS) is an increasingly prevalent disease in our aging population. Although multiple risk factors for AVS have been elucidated, medical therapies capable of slowing down disease progression remain unavailable.

Soft, Degradable, and Magnetic Microcarriers for Encapsulation and Guided Transport of Drugs and 3D Spheroids

Advanced Materials, EarlyView.
This work presents soft, degradable hydrogel microcarriers that combine magnetic responsiveness with the ability to host multiple therapeutic and cellular components. Produced by droplet microfluidics, the carriers maintain structural integrity during manipulation, permit controlled breakdown under physiological conditions, and enable guided motion for

Protein Disulfide Isomerase Disassembles TDP‐43/G3BP1 Condensates and Antagonizes TDP‐43 Pathological Aggregates

Advanced Science, EarlyView.
Cytoplasmic aggregation of TDP‐43 is a common pathological feature in amyotrophic lateral sclerosis, frontotemporal lobar degeneration, and Alzheimer's disease with TDP‐43 pathology. This study reports that wild‐type PDI slows down phase separation of TDP‐43 through direct interaction with TDP‐43.

Multifactorial analysis of radiochemical purity in high-activity 177Lu-labeled theranostics: impact of precursor source, 177Lu form, and production parameters

EJNMMI Radiopharmacy and Chemistry
Background Lutetium-177 (177Lu) theranostics have revolutionized personalized cancer treatment, particularly with FDA-approved therapies like [177Lu]Lu-DOTA-TATE for neuroendocrine tumors and [177Lu]Lu-PSMA for prostate cancer.
