  • Chemometric Spectroscopy

    Chemometric Spectroscopy is the term used to describe the direct combination of a spectroscopic measurement with a chemometric data evaluation procedure, typically a multivariate statistic method, so providing quick and reliable deduction of the qualitative and quantitative properties of a sample from its spectrum. A multi-linear regression (MLR) or partial least squares (PLS) regression is usually used for the quantitative determination of individual or combined parameters, while substance identification generally relies on techniques such as discriminant or cluster analysis. more

  • Simulated Moving Bed Chromatography: from chiral molecules to biocompounds

    The Simulated moving bed (SMB) technology was developed in the '60s and used for large-scale separations of hydrocarbons in the oil industry. The SMB concept has been extended towards new fields of application since then, first in the large-scale food industry, e.g. separation of sugars, and lately in the separation of fine chemicals, particularly chiral molecules where it is now an established technique more

  • Analysis of the DNA Methylation Patterns at the BRCA1 CpG Island

    Germ-line alterations of the BRCA1 gene confer a lifetime risk of 40% for ovarian cancers and of 40%-80% for ­breast cancers. It is likely that BRCA1 acts as a tumor suppressor gene. BRCA1 involvement in breast cancers does not seem to be restricted to familial cancers. Despite the absence of somatic mutations in the breast tissues, a down regulation of BRCA1 expression is associated with malignancy in human sporadic breast cancers. more
