Near-triploid and near-tetraploid acute lymphoblastic leukemia of childhood.
Cytogenetic and DNA flow cytometric analyses of leukemic cells from 1,971 children with newly diagnosed acute lymphoblastic leukemia (ALL) identified stem lines with modal chromosome numbers greater than 65 in 26 patients (1.3%). Near-triploidy (66 to 73 chromosomes) was found in six cases and near-tetraploidy (82 to 94 chromosomes) in 20. A striking morphologic finding was the presence of clum...

متن کاملMeiotic chromosome pairing in triploid and tetraploid Saccharomyces cerevisiae.
Meiotic chromosome pairing in isogenic triploid and tetraploid strains of yeast and the consequences of polyploidy on meiotic chromosome segregation are studied. Synaptonemal complex formation at pachytene was found to be different in the triploid and in the tetraploid. In the triploid, triple-synapsis, that is, the connection of three homologues at a given site, is common. It can even extend a...
متن کاملDelayed meiosis and polar body release in eggs of triploid Pacific oysters, Crassostrea gigas, in relation to tetraploid production.
The dynamics of polar body release are important for creating polyploid shellfish. For producing triploids, these dynamics concern meiosis in diploid eggs and are well understood. For creating tetraploids, eggs from triploids are employed and the dynamics, variation, and environmental influences upon polar body release are less studied. We investigated the effects of several agents on the timin...
متن کاملstudy the effects of low level laser diode on no production and healing of diabetic and cortisone acetate and normal wounded sd rats
nitric oxide (no) is a small molecule synthesized by most of mammalian cells with diverse biological activities including vasodilatation, host defense and wound healing. impaired wound healing is a common occurrence among diabetics and patients receiving glucocorticoid therapy. on the other hand the application of laser in biomedical area have been increased. thus, the current studies were desi...
