We evaluated the efficiency and sensitivity of CCD microscopy to the detection of the genomic origin of marker chromosome with partial trisomy in cells from the bone marrow of the patient with Myelodysplastic syndrome (MDS-RA). The results of our fluorescent in situ hybridization (FISH) studies with DNA probes, performed for the identification of the chromosomal origin of the marker chromosome in metaphases, confirm previous findings. Ability of this procedure to integrate fluorescence signals has contributed to the increase in sensitivity of FISH in interphase cells.","PeriodicalId":213764,"journal":{"name":"Proceedings of the 2nd International Conference on Bioelectromagnetism (Cat.

The lengths of each stage of the cell cycle were determined by cell counts using Feulgen-stained microscope slides and a video microscope. The length of time taken for each stage of the cell cycle for all of the treatments differed significantly from the controls. In particular, prophase appeared longer for all treatments. The implication of this is that the all of the magnetic field treatments had some affect on chromosome coiling.","PeriodicalId":213764,"journal":{"name":"Proceedings of the 2nd International Conference on Bioelectromagnetism (Cat.

In the latter model 19, 116, 326, and 678 clusters were formed from 7046 locations in cardiac muscles keeping the relative mean square errors less than 10, 4, 2, and 1%, respectively, from simulations by transforming the sources individually.","PeriodicalId":213764,"journal":{"name":"Proceedings of the 2nd International Conference on Bioelectromagnetism (Cat.

Based on the simulation result and the FE model analysis, a modeling improvement is proposed in order to achieve the best simulation result for the particular requirements of the resistivity reconstruction of the human head.","PeriodicalId":213764,"journal":{"name":"Proceedings of the 2nd International Conference on Bioelectromagnetism (Cat.

Three different study protocols were used for signal registration at spontaneous, fixed paced and incrementally paced heart rates. The results demonstrated high correlation between the surface QT-interval and MAP duration at various heart rates. The findings afford the opportunity to use QT-interval measured from surface ECG for modelling processes requiring endocardial electrogram registration.","PeriodicalId":213764,"journal":{"name":"Proceedings of the 2nd International Conference on Bioelectromagnetism (Cat.
