Production Of 11C‐Labeled Amides Via “In‐Loop” 11C‐Carbonylation
Asian Journal of Organic Chemistry, EarlyView.The current work utilizes carbon‐11 labelled aroyl dimethylaminopyridinium salts in a two‐step in‐loop carbonylative cross‐coupling reaction of aryl halides with [¹¹C]CO yielding a diverse range of carbon‐11 labelled primary benzamides with good to excellent yields.

Feasibility study of the positronium imaging with the J-PET tomograph [PDF]
, 2018 A detection system of the conventional PET tomograph is set-up to record data from e+ e- annihilation into two photons with energy of 511 keV, and it gives information on the density distribution of a radiopharmaceutical in the body of the object. In this paper we explore the possibility of performing the three gamma photons imaging based on ortho ...

Premenopausal bilateral oophorectomy and Alzheimer's disease imaging biomarkers later in life
Alzheimer's &Dementia, EarlyView.Abstract INTRODUCTION Premenopausal bilateral oophorectomy (PBO) before the age of 46 years is associated with an increased risk of dementia. We investigated the long‐term effects of PBO performed before age 50 years on amyloid beta (Aβ), tau, and neurodegeneration imaging biomarkers of Alzheimer's disease (AD).

Polycrystalline para-terphenyl scintillator adopted in a $β^-$ detecting probe for radio-guided surgery [PDF]
Journal of Physics: Conference Series 620 (2015) 012009, 2015 A radio-guided surgery technique exploiting $\beta^-$ emitters is under development. It aims at a higher target-to-background activity ratio implying both a smaller radiopharmaceutical activity and the possibility of extending the technique to cases with a large uptake of surrounding healthy organs.
