By counting silver grains in autoradiographs of lampbush chromosomes the rates of incorporation of [3H]adenine, [3H]cytidine, [3H]guanosine and [3H]uridine, administered separately, into RNA on the giant loops of chromosome II of Notophthalmus viridescens, were compared with the rates of incorporation of these same precursors into RNA on other, unidentified loops. The overall rate of RNA transc...

Karger AG, Basel Accessible online at: www.karger.com/cgr The Editors and Publisher of this Journal join us in congratulating Niels Bentzen Atkin BA, MRCS, LRCP, MD, DMRT, FIAC on his 90th birthday. Niels is one of the pioneers of human cytogenetics, most particularly tumour cytogenetics. Niels was one of the first to co...

In the textbook view, the ratio of X chromosomes to autosome sets, X:A, is the primary signal specifying sexual fate in Drosophila. An alternative idea is that X chromosome number signals sex through the direct actions of several X-encoded signal element (XSE) proteins. In this alternative, the influence of autosome dose on X chromosome counting is largely indirect. Haploids (1X;1A), which poss...

Background: Chest compression with adequate depth and number is one of the main indicators of high-quality cardiopulmonary resuscitation (CPR). Nevertheless, no proper counting technique is suggested to provide sufficient number of massages. Aim: To compare the effects of three techniques of chest compression counting on the quality of CPR and rescuer fatigue. Method: Inthis clinical trial, 30 ...

Aim: Evaluation of the significance of micronuclei (MN) as biomarkers for evaluation the risk of malignant transformation in uterine cervix. MN are intracytoplasmic inclusion bodies from chromatin fragments or whole chromosomes. Their presence in cells is a reflection of chromosomal aberration during cellular mitosis. Patients and methods: MN screening was done in all selected cytopathological ...

Conventional cytogenetic is the standard technique for detection of Philadelphia (Ph) chromosome in chronic myeloid leukemia (CML). Evaluation of abelson murine leukemia/breakpoint cluster region (abl/bcr) fusion using dualcolour fluorescence in situ hybridization (D-FISH) is an alternative approach allowing rapid and reliable detection of the disease. We employed the technique of interphase D-...
