Possible occurrence of amitotic cell division during haemopoiesis in the Urodeles
- BiologyComparative Haematology International
The liver haemopoietic activity of three species of Urodeles was examined and the presence in the bloodstream samples of cells (erythrocytes) with replicating DNA, nuclear constrictions and binucleations is consistent with a situation of direct nuclear division.
Crossed renal ectopia with pelvic lipomatosis: a new syndrome involving chromosome 1
- Medicine, BiologyHuman Genetics
An 18-year-old male patient who possesses both kidneys on one side (crossed renal ectopia) and pelvic lipomatosis can be assigned to a new syndrome characterised by a whole-chromosome translocation involving chromosomes 1 and 6.
Centromeric alpha satellite DNA amplification and translocation in an unusually large chromosome 14p+ variant
- BiologyHuman Genetics
In situ hybridisation of metaphase cells with an alpha satellite DNA probe specific for human acrocentric chromosomes demonstrated a significantly increased amount of centromeric alpha sequences in WSi-var(14)(p+).
Amplification of satellite III DNA in an unusually large chromosome 14p+ variant
- BiologyHuman Genetics
The origin of the extra chromosomal material in WSm-var(14) is proposed to be a result of amplification of contiguous satellite III DNA that is normally present in the short arm of chromosome 14.
Severe anomalies associated with ring chromosome 7.
- MedicineAmerican journal of medical genetics
A newborn infant with the polyasplenia sequence, intrauterine growth retardation, cutaneous nevi, and minor anomalies was found to have mosaicism for ring chromosome 7. This patient's anomalies are…

Cytological Evidence for Crossing-Over in vitro in Human Lymphoid Cells
- Biology, MedicineScience
In human blood cells dividing in vitro two chromosomes are occasionally found intimately associated in a quadriradial configuration (Qr), considered cytological evidence that somatic crossing-over may occur in mammalian cells.

Chromosome breakage by 1-methyl-2-benzylhydrazine in mouse cancer cells.
- Biology, ChemistryCancer research
The induction of chromatid translocations by 1-methyl-2-benzylhydrazine was studied in a number of malignant and normal mammalian cell types and in narcissus root cells, and no translocations were observed in treated or untreated normal tissues in vivo or in vitro.
Distribution of chromosome breaks in measles, Fanconi's anemia and controls.
The results suggest that analysis of the localization of chromosome breaks might give information on the cause and mechanism of chromosome breakage.

Control of chromosome inactivation.
- BiologyAnnual review of genetics
This paper is concerned with this order of genetic regulation and particularly with the behavior of the mammalian X chromosome, and those aspects of the system that have some bearing on possible control mechanisms are discussed.
