The compound interest formula [1] is as follows: Where: T = Total accrued, including interest. PA = Principal amount. roi = The annual rate of interest for the amount borrowed or deposited. t = The number of times the interest compounds yearly. y = The number of years the principal amount has been borrowed or deposited.

The cells of an epithelium act as gatekeepers of the body, controlling permeability by allowing selective transfer of materials across its surface. All substances that enter the body must cross an epithelium. Many epithelial cells are capable of secreting mucous and other specific chemical compounds onto their apical surfaces.

Irrespective of the cell model chosen, e.g. Caco-2, HT29 or Caco-2/HT29 co-cultures, the main readout parameters are effects on the epithelial barrier function, absorption or transepithelial transport of the test compound. The reliability of such studies depends on the uniformity and integrity of the confluent and polarized cell monolayer.
