  • 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

  • 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 qual more

  • Beyond Quality Control

    Product quality in any arena can be traced back to variations in parts, materials, people, and processes. And since it has been observed that all work can be broken down into processes, all processes, manufacturing or administrative in nature, have inherent variability more
