17β-Nandrolone (17β-NT) is one of the most frequently misused anabolic steroids in meat producing animals. As a result of its extensive metabolism combined with the possibility of interferences with other endogenous compounds, detection of its illegal use often turns out to be a difficult issue.

Synthesis of trans β-Lactams of Estrane Series
Collection of Czechoslovak Chemical Communications, 199517,17-Ethylenedioxy-1,3,5(10)-estratrien-3β-ol (I) was converted into ethyl ester II by reaction with ethyl chloroacetate in the presence of potassium. The ethyl ester II on reaction with hydrazine gave hydrazide III, which on condensation with aromatic aldehydes gave Schiff bases IVa-IVd. The reaction of Schiff bases IVa-IVd with chloroacetyl chloride

Production et accumulation de sédiments biogènes sur les estrans sableux.
1995Les tests des organismes marins sont à l'origine d'une production renouvelable de sédiments calcaires et siliceux sur les plages. Sur la plage de Combrit dans le sud-Finistère (Bretagne occidentale, France), les sables de l'estran montrent des teneurs en carbonates de calcium d'origine organique variant de 7 à 46,5%.
