Abstract Background [F-18]fluorodeoxyglucose positron emission tomography/computed tomography is routinely used for assessing Takayasu arteritis patients. However, extra-vessel [F-18]fluorodeoxyglucose uptake has not been evaluated in detail in these

Positron-emission tomography/computed tomography (PET/CT) in the head and neck region is susceptible to artifacts caused by dental restorations. Metal artifact reduction is an established technology that can be used to improve the quality of CT image

A man in his 60s with severe trismus was referred to our hospital. Based on computed tomography (CT), positron emission tomography/computed tomography (PET/CT), and biopsy, his initial diagnosis at another hospital was oropharyngeal cancer with cervi

The aim of this study was to investigate the diagnostic performance of whole-body [C]acetate PET/CT in less aggressive or indolent lymphomas, wherein [F]FDG PET/CT would exhibit limited sensitivity.Between September 2016 and May 2018, we prospectivel

Grignard reagents (R2MgBr; R2 = Me, p-tolyl) regioselectively attacked the α-carbon of the bridgehead double bond of methyl- and benzylazafulleroids (only R2 = Me) in contrast to the β-carbon attac...

Oxidation of azafulleroids with peracids regenerated C60 depending on the N-substituents. Alkyl-substituted azafulleroids preferred the oxidation of nitrogen to afford N-oxides as possible intermediates for C60 in moderate yields. Phenyl- and tosyl-s

Nanocomposite films of polystyrene (PS) and poly(methyl methacrylate) (PMMA) were prepared by loading four variations of fullerenes such as pristine C60, multiarylated [60]fullerenes with tolyl (tolyl-C60) and phenol groups (phenol-C60), and [6,6]-ph

Azafulleroid, amino-bridged [5,6]-open fullerene, has the ambident N/C basicity of the incorporated enamine moiety. Acid-catalyzed arylation of N-substituted azafulleroids proceeded via two types of initial N/C protonation to perform monoarylation or

We studied the kinetics of the Diels-Alder reaction of Li(+)-encapsulated [60]fullerene with 1,3-cyclohexadiene and characterized the obtained product, [Li(+)@C60(C6H8)](PF6(-)). Compared with empty C60, Li(+)@C60 reacted 2400-fold faster at 303 K, a
