DOPAMINE TRANSPORTERS IN STRIATUM CORRELATE WITH DEACTIVATION IN THE DEFAULT MODE NETWORK DURING VISUOSPATIAL ATTENTION.

Dopamine transporters in striatum correlate with deactivation in the default mode network during visuospatial attention.

BACKGROUND:Dopamine and dopamine transporters (DAT, which regulate extracellular dopamine in the brain) are implicated in the modulation of attention but their specific roles are not well understood.Here we hypothesized that dopamine modulates attention by facilitation of brain deactivation in the default mode network (DMN).Thus, higher striatal DA

Testing for extragenital Neisseria gonorrhoeae and Chlamydia trachomatis: At-home pharyngeal and rectal self-swabs are non-inferior to those completed in healthcare settings.

IntroductionThe rates of gonorrhea and chlamydia have been increasing in the years preceding the COVID19 pandemic.Because most gonorrhea and chlamydia infections are located in the oropharynx and rectum for men who have sex with men (MSM), and because at-home self-collected swabs for these infections are not licensed by Health Canada or the United

A clearing house for diagnostic testing: the solution to ensure access to and use of patented genetic inventions?

In genetic diagnostics, the emergence of a so-called "patent thicket" is imminent.Such an overlapping set of patent rights Artwork may have restrictive effects on further research and development of diagnostic tests, and the provision of clinical diagnostic services.Currently, two models that may facilitate access to and use of patented genetic inv

A neuro-mechanical model of a single leg joint highlighting the basic physiological role of fast and slow muscle fibres of an insect muscle system.

In legged animals, the muscle system has a dual function: to produce forces and torques necessary to move the limbs in a systematic way, and to maintain the body in a static position.These two functions are performed by the contribution of specialized motor units, i.e.motoneurons driving sets of specialized muscle fibres.With reference to their ove

Extensive Discussions of the Eddy Dissipation Concept Constants and Numerical Simulations of the Sandia Flame D

The indisputable wide NEFF N90 T66TS6RN0 61cm Induction Hob Black use of the Eddy Dissipation Concept (EDC) implies that the resulting mean reaction rate is reasonably well modeled.To model turbulent combustions, an amount of EDC constants that differ from the original values was proposed.However, most of them were used without following the nature
