Clinical grade (Good Manufacturing Practice, GMP) CD4posCD25high Treg isolation by a magnetic bead based method is now feasible using the CliniMACS system [31], [32], albeit that Treg purity is suboptimal (50 60%).
During the past 25 years, a wealth of algorithms have been proposed and ICA-based methods are now extensively and successfully applied to solve many practical real-life problems such as biomedical signal analysis and processing, wireless communications, data mining, speech enhancement, image recognition, etc. (see [3] for details).
These two science-based methods are now solid prevention options for mixed-status couples considering conception.
PCR-based methods are now routinely used for laboratory diagnosis of pathogens, with acceptably high specificity.
With the development of commercial array platforms and the surging use of next-generation sequencing, bisulfite-based methods are now the most widely used methodology, and are well-suited for the types of biospecimens collected in epidemiologic studies.
While PCR-based methods are now the commonly accepted gold standards for these types of analysis, relatively high costs, time-consuming assay development or the need for a priori information about species-specific sequences constitute major limitations.
Newly available computational tools based on multilocus methods are now applied to 'species' delimitation [ 15], inference of the relationships among previously defined species [ 16- 18], or both [ 19, 20].
Classic QSAR methods, developed by Hansch [5], provided a foundation on which numerous QSAR methods are now based: the correlation of physicochemical properties to activity using multivariable regression.
Faster LPIC detectors based on faster iterative methods such as the steepest descent and the conjugate gradient methods are now introduced.
