Are de novo rea(21;21) chromosomes really de novo?

We report a rare case of recurrent trisomy 21 caused by an isochromosome 21q and what is very likely to be maternal germ-line cell mosaicism. Over 90% of cases of rob(21;21) reported in the literature are due to an isochromosome 21q, with a risk of recurrence of more than 10%.

The John–Nirenberg inequality with sharp constants Meilleures constantes dans l’inégalité de John–Nirenberg

Article history: Received 14 March 2013 Accepted after revision 3 July 2013 Available online 29 July 2013 Presented by Yves Meyer We consider the one-dimensional John–Nirenberg inequality: ∣∣{x ∈ I0: ∣∣ f (x)− f I0 ∣∣>α}∣∣ C1|I0|exp ( − C2 ‖ f ‖∗ α ) . A. Korenovskii found that the sharp C2 here is C2 = 2/e. It is shown in this paper that if C2 = 2/e, then the best possible C1 is C1 = 2 e4/e. ©...
