SummaryA case of a 49-year-old man suffering from bilateral adrenocortical carcinoma with local and secondary rapid progression is reported. The results of adrenocortical scintigraphy (NP 59) and histological findings allowed the diagnosis. This case report and a literature review showed the importance of using adrenocortical scintigraphy as a complementary imaging procedure of CT or MR images.

The work describes a new chemical means of visualising latent fingerprints (fingermarks) using tropolone. Tropolone reacts with amino acids within the fingermark residue to form adducts that absorb UV radiation. These adducts provide useful contrast on highly-fluorescent prous surfaces will illuminated with UV radiation. The conjugated seven-membered ring of the tropolone adduct can be reacted further diazonium salts, which is demonstrated here with formation of two dyes. The methodology is extremely rapid, occurring in minutes with mild heating, and can be applied before ninhydrin in a chemical detection sequence. <br>

Benzotriazolylacetone is coupled with aromatic diazonium salts to yield arylhydrazones, which can be condensed with ethyl cyanoacetate yielding pyridazinones whose reactivity towards activated double bond systems is investigated.
