We describe three patients with the cutaneous manifestations of hypomelanosis of Ito. Two, with unusual abnormalities of their toes, had a mixture of diploid and triploid cells in cultured skin fibroblasts. The published clinical descriptions of hypomelanosis of Ito and diploid-triploid mosaicism are reviewed. Chromosome heteromorphisms, HLA types, and DNA fingerprints were studied in an attemp...

In the present study we describe the localization of proteasomes in human oocytes, apoptotic preimplantation embryos, and triploid preimplantation embryos by means of immunolabelling with the MCP21 monoclonal antibody detected by confocal microscopy. While in the oocytes proteasomes are scattered throughout the cytoplasm, in the pronuclear zygote they appear to concentrate at the periphery of t...

ABSTRACT Triploid watermelon is highly appreciated by the most demanding markets, and due to its small size, it ideal for consumption families. With growth in areas cultivated with seedless worldwide, there a demand development of tetraploid germplasm obtain triploid hybrids better agronomic performance. This study performed two tests induce polyploidy powdery mildew–resistant line developed Em...
