Amyloid-Targeting PET Tracer [18F]Flutemetamol Accumulates in Atherosclerotic Plaques

Molecules, 2019
Atherosclerosis is characterized by the accumulation of oxidized lipids in the artery wall, which triggers an inflammatory response. Oxidized low-density lipoprotein (ox-LDL) presents amyloid-like structural properties, and different amyloid species have

Penetration, distribution, and elimination of remofuscin/soraprazan in Stargardt mouse eyes following a single intravitreal injection using pharmacokinetics and transmission electron microscopic autoradiography: Implication for the local treatment of Stargardt’s disease and dry age‐related macular degeneration

Pharmacology Research & Perspectives, 2020
Age‐related macular degeneration (AMD) is the leading cause of blindness in older people in the developed world while Stargardt's disease (SD) is a juvenile macular degeneration and an orphan disease.

In Vitro and In Vivo Characterization of Selected Fluorine-18 Labeled Radioligands for PET Imaging of the Dopamine D3 Receptor

Molecules, 2016
Cerebral dopamine D3 receptors seem to play a key role in the control of drug-seeking behavior. The imaging of their regional density with positron emission tomography (PET) could thus help in the exploration of the molecular basis of drug addiction.

Alterations in Cerebral Blood Flow and Glucose Utilization in Mice Overexpressing the Amyloid Precursor Protein

Neurobiology of Disease, 2002
We have used quantitative autoradiographic techniques to study the relationship between cerebral blood flow (CBF) and glucose utilization (CGU) in two lines of transgenic mice overexpressing Swedish mutant amyloid precursor protein (APP) and APP-derived ...

Decreased MK-801 Binding in Discrete Hippocampal Regions of Prion-Infected Mice

Neurobiology of Disease, 2001
The neurochemical alterations associated with neurodegeneration in prion diseases are not well defined. It is therefore of interest to study the influence of prion infection on messenger molecules and their receptors.

Analysis of capecitabine metabolites in conjunction with digital autoradiography in a murine model of pancreatic cancer suggests extensive drug penetration through the tumor

Pharmacology Research & Perspectives, 2022
Previously published digital autoradiography of 3H‐labeled capecitabine reveals a near‐uniform distribution of activity throughout a murine pancreatic model.

Differential Sphingosine-1-Phosphate Receptor-1 Protein Expression in the Dorsolateral Prefrontal Cortex Between Schizophrenia Type 1 and Type 2

Frontiers in Psychiatry, 2022
Understanding the etiology and treatment approaches in schizophrenia is challenged in part by the heterogeneity of this disorder. One encouraging progress is the growing evidence that there are subtypes of schizophrenia.

Synthesis and Evaluation of 125I Labeled Chalcone Derivatives Containing Bithiophene Moiety as Potential Aβ Probes

Journal of Isotopes, 2015
In continuation of the investigation on the bithiophene structure as potential Aβ probes, two halogenated chalcone derivatives containing bithiophene moiety were designed and evaluated as imaging probes for Aβ plaques.

Actinide bioimaging in tissues: Comparison of emulsion and solid track autoradiography techniques with the iQID camera. [PDF]

PLoS ONE, 2017
This work presents a comparison of three autoradiography techniques for imaging biological samples contaminated with actinides: emulsion-based, plastic-based autoradiography and a quantitative digital technique, the iQID camera, based on the numerical ...
