Dicynodonts, a highly successful group of Palaeozoic tetrapods, were herbivores with keratinous beaks, and were frequently equipped with large, neomorphic tusks. Diictodon is a particularly abundant dicynodont genus, allowing statistical investigation of its palaeobiology. Anatomical, morphometric and distributional analyses provide evidence of sexual dimorphism, based on the presence or absenc...
Truncation mutations in FAM83H (family with sequence similarity 83, member H) cause autosomal dominant hypocalcified amelogenesis imperfecta (ADHCAI), but little is known about FAM83H function and the pathogenesis of ADHCAI. We recruited three ADHCAI families and identified two novel (p.Gln457*; p.Lys639*) and one previously documented (p.Q452*) disease-causing FAM83H mutations. We generated an...
Approximately 170 kilobase pairs (kb) of contiguous DNA sequences derived from bands 3A3,4 of the Drosophila melanogaster X chromosome have been isolated by molecular cloning. Sequences required for the wild-type expression of the zeste locus are located within a 6-kb fragment of this chromosomal region, as shown by phenotypic rescue of zeste mutants in P element-mediated germ-line transformati...
Pleuropulmonary blastoma (PPB) is the most frequent pediatric lung tumor and often the first indication of a pleiotropic cancer predisposition, DICER1 syndrome, comprising a range of other individually rare, benign and malignant tumors of childhood and early adulthood. The genetics of -associated DICER1 tumorigenesis are unusual in that tumors typically bear neomorphic missense mutations at on...
In this study we elucidated the role of nonactive JNK in regulating p53 stability. The amount of p53-JNK complex was inversely correlated with p53 level. A peptide corresponding to the JNK binding site on p53 efficiently blocked ubiquitination of p53. Similarly, p53 lacking the JNK binding site exhibits a longer half-life than p53(wt). Outcompeting JNK association with p53 increased the level o...
On the basis of the principle that topological quantum phases arise from the scattering around space-time defects in higher dimensional unification, a geometric model is presented that associates with each quantum phase an element of a transformation group.
-We present a derivation of the Berry quantum adiabatic phase using group theory. Our formalism is used to discuss possible manifestations in Atomic Physics and to investigate the new cyclic quantum phase recently introduced by Aliaronov and Anandan. J. Physique 48 (1987) 1401-1406 SEPTEMBRE 1987,
