One of the main in vitro permeability assays used in the pharmaceutical industry has been for many years the Caco-2 monolayer. Therefore, most of the in silica models developed to predict permeability were based on Caco-2 data. Hou and Johnson produced a couple of reviews that comprehensibly summarizes the recent efforts using Caco-2 permeability data [92, 94]. All those models are designed to predict the influx or apparent permeability of drugs in the same direction as intestinal absorption occurs, that is, from the apical to the basal side of the cell line, regardless of the extent of active transport involved in the permeation process. 

The chapter is organized as follows. First, to establish a common language, we define some common terms from both a pharmaceutical and an engineering perspective. Subsequently, we review model-based design and optimization as a framework for product and process development and optimization, process scale-up, and continuous improvement activities. The role of process and analytical technology (PAT) methods and principles in this framework is discussed. Finally, the main areas requiring effort are identified. 

The innovative potential and the ingenuity which have gone into designing libraries, vectors and selection protocols are impressive. However, considerable input has come from structural modelling and design considerations, in the proliferation of phage-display scaffolds to provide constrained variable epitopes in different environments or contexts . In addition the method has been used to understand protein folding, protein-protein interactions and structure-function relationships in catalysis. I hope that, in this review,... 

The modeling and design of a three-phase reactor requires the knowledge of several hydrodynamic (e.g., flow regime, pressure drop, holdups of various phases, etc.) and transport (e.g., degree of backmixing in each phase, gas-liquid, liquid-solid mass transfer, fluid-reactor wall heat transfer, etc.) parameters. During the past decade, extensive research efforts have been made in order to improve our know-how in these areas. Chapters 6 to 8 present a unified review of the reported studies on these aspects for a variety of fixed bed columns (i.e., co-current downflow, co-current upflow, and counter-current flow). Chapter 9 presents a similar survey for three-phase fluidized columns.

It is not the aim of this section to introduce the reader to all the areas listed above. Our goal is modest. We describe some of the theoretical developments which arose from studies of caricatures of proteins. Such models were designed in order to imderstand certain general features about protein structures and how these are kinetically reached. To keep the bibliography compact we mostly cite review articles. The interested reader can find the original papers in these cited works. We hope that this short introduction will entice the reader to delve into the ever surprising world of biological macromolecules.
