perrault's syndrome (p.s.) is rare. the combination of gonadal dysgenesis and hearing loss was accompanied by 46,xxkaryotype in three sisters with parental consanguineous marriage. genetic investigation revealed normal female karyotype, positive liarr and negative fluorescence ipj-bodies, which was confirmed by molecular study on the basis of fluorescence in situ hybridization (pish), with appl...

background: parental anxiety while waiting for the results of amniocentesis has been investigated by many authors. it seems that the implementation of faster techniques such as fluorescence in-situ hybridization (fish) will have some benefits in reducing this anxiety. besides the patients' attitudes to choosing this method, gynecologists who are the persons responsible for treatment, must feel ...

background: it has been claimed that by using different washing methods, the sperms can be separated according to size, motility, density, chromosomal content and surface markings and charge. these methods also reduce sperm chromatin deficiencies and screen the sperms before applying in assisted reproduction techniques. objective: this study compared simple density gradient methods and a combin...

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 dual-colour 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...

in this study, the bacterial diversity in the activated sludge system of a full-scale municipalwastewater treatment plant in dubai was monitored over a period of one year using ribosomal rna (rrna)targeted oligonucleotide probes for a defined phylogenetic group of bacteria by the fluorescence in situhybridization (fish) technique. the largest fraction of the bacterial community in the sludge sa...
