Recent Developments in Carbon-11 Chemistry and Applications for First-In-Human PET Studies

open access: yesMolecules, 2023
Positron emission tomography (PET) is a molecular imaging technique that makes use of radiolabelled molecules for in vivo evaluation. Carbon-11 is a frequently used radionuclide for the labelling of small molecule PET tracers and can be incorporated into

Anion emission from water molecules colliding with positive ions: Identification of binary and many-body processes

open access: yes, 2015
It is shown that negative ions are ejected from gas-phase water molecules when bombarded with positive ions at keV energies typical of solar-wind velocities.

On the adsorption and reactivity of element 114, flerovium

open access: yesFrontiers in Chemistry, 2022
Flerovium (Fl, element 114) is the heaviest element chemically studied so far. To date, its interaction with gold was investigated in two gas-solid chromatography experiments, which reported two different types of interaction, however, each based on the ...

Development of novel fluorine-18 labeled PET radioligands for monoamine oxidase B (MAO-B) [PDF]

open access: yes, 2013
Monoamine oxidases (MAO-A and MAO-B) are important enzymes regulating the levels of monoaminergic neurotransmitters. Selectiv e and irreversible MAO-B inhibitors such as L -deprenyl and rasagiline are clinically used for the t reatment of ...

Should archaeologists care about 14C inter-comparisons? Why? A summary report on SIRI [PDF]

open access: yes, 2017
Radiocarbon (14C) dating is used widely in many projects as a basis for the creation and testing of chronological constructs. 14C measurements are by their nature complex and the degree of sample pretreatment varies considerably depending on the material.

Home‐based sleep monitoring reveals associations between amyloid accumulation and sleep alterations in individuals with subjective and mild cognitive impairment

open access: yesAlzheimer's &Dementia, Volume 22, Issue 4, April 2026.
Abstract INTRODUCTION Sleep disturbances have been associated with Alzheimer's disease (AD), but their relevance in preclinical stages, such as subjective cognitive decline (SCD), and their relationship with brain pathology remain unclear. METHODS We used a portable sleep‐monitoring headband over four consecutive nights to assess sleep in 19 ...

Two distinct components of the delayed single electron background signals in liquid xenon emission detectors [PDF]

open access: yes, 2017
Single electron background signals with millisecond timescales are known to follow ionizing events in liquid/gas xenon emission detectors. Due to the long timescale, these signals can present a limiting background to the low-energy threshold of dark ...
