Abstract: The present invention provides a method for evaluating oral health, in particularly for evaluating a risk for suffering from periodontal disease, comprising: (1) providing an oral sample of a subject; (2) detecting at least two indicator microbes in the oral sample; and (3) analyzing amounts of the at least two indicator microbes; wherein when each of the amounts of the at least two indicator microbes is higher than a standard value for an amount of a corresponding indicator microbe, it indicates that the subject has a high risk for suffering from periodontal disease.

Abstract: The present invention uses 2-dimensional differential gel electrophoresisgel (2D-DIGE) and mass spetrum techniques to identify breast cancer biomarkers in transformed breast cells. In summary, the present invention identifies numerous putative breast cancer markers from various stages of breast cancer. The results of the invention aids in developing proteins identified as useful diagnostic and therapeutic candidates on breast cancer research.
