in previous years, identification of fetal cells in maternal blood circulation has caused a new revolution in non-invasive method of prenatal diagnosis. low number of fetal cells in maternal blood and long-term survival after pregnancy limited the use of fetal cells in diagnostic and clinical applications. with the discovery of cell-free fetal dna (cffdna) in plasma of pregnant women, access to...

Genetic information can be highly sensitive and can be used to identified its source. To conceal genetic information, cryptographic methods can be applied to genetic material itself, concealing sensitive information prior to the generation of sequence data. The cryptographic method described here uses randomly divided subsets of barcodes and random pooling to securely generate pools of genetic ...

The bioinformatical methods to detect lateral gene transfer events are mainly based on functional coding DNA characteristics. In this paper, we propose the use of DNA traits not depending on protein coding requirements. We introduce several semilocal variables that depend on DNA primary sequence and that reflect thermodynamic as well as physico-chemical magnitudes that are able to tell apart th...
