6- 18 F-fluoro-l-dopa ( 18 F-FDOPA) has proven to be a useful radiopharmaceutical for the
evaluation of presynaptic dopaminergic function using PET. In comparison to electrophilic …

Fluorine-18 has become the most widely used short-lived radioisotope for the labeling of
radiopharmaceuticals for positron emission tomography (PET; 18F, t1/2= 109.7 min).[1] …

Background Several fluorine-18 labelled fluoroamino acids have been evaluated as tracers
for the quantitative assessment of cerebral protein synthesis in vivo by positron emission …

We describe a new synthesis of chalcogenochromones and of some of their oxygen, sulfur,
selenium and tellurium derivatives. The synthesis involves acidic cyclisation of (o …

Humans are less responsive to the surrounding environment during sleep. However, the extent
to which the human brain responds to external stimuli during sleep is uncertain. We used …

Social networks websites, and specially the LinkedIn platform, have changed the landscape
of recruitment and personnel selection to a unified organizational process. Thus, apart from …

The descending pain modulatory system (DPMS) comprises a network of cortical and subcortical
brain and brainstem regions that can inhibit nociceptive afferent brain input (Ossipov et …

In rats, the firing sequences observed in hippocampal ensembles during spatial learning are
replayed during subsequent sleep, suggesting a role for posttraining sleep periods in the …

Functional magnetic resonance imaging (fMRI) was used to investigate the cerebral correlates
of motor sequence memory consolidation. Participants were scanned while training on an …
