Fig. 6 Disease severity in CF patients is determined by the amount of mutant CFTR activity. A In vivo data were pooled from multiple published studies using NPD techniques to measure CFTR-mediated Cl- secretion in subjects with pancreatic insufficiency (PI), pancreatic sufficiency (PS), or congenital bilateral absence of the vas deferens (CBAVD) and obligate heterozygotes (carriers). CFTR-mediated Cl- secretion in each study was normalized to the non-CF control subject and expressed as % wild-type (wt)-CFTR. B The severity of lung disease in each group was determined from the longitudinal decline in FEVi and classified as severe (red 3%/year), mild (yellow l%/year), or no (green) lung disease...

Macroscopically aligned BCP thin films provide invaluable robust, versatile, chemically functionalizable nanopattemed surfaces. Due to the interplay between film thickness, nanostructure and alignment, careful and complex processes are required to reach large scale alignment mmiodomams. Moreover, with the multiplication of the actual possibilities in term of copolymer architecture, monomer choices, advanced substrates, high-tech deposition and treatment processes, as well as new time- or spatially resolved analysis techniques, the field of nanopattemed BCP thin films is still ready to provide remarkable model study subjects as well as routes for defect-free or tailor-made nanomaterials for technological applications. 

The subject matter covered below is divided into sections according to the structure of the redox unit(s). This review is restricted primarily to materials for which well-defined redox behavior has been repiorted, usually involving cyclic voltammetric studies and other electrochemical techniques in solution. Unraveling the electron transfer processes in laiger macromolecules which contain multiple redox sites can be very challenging, thus for some systems model branched oligomers have been studied in detail, and this work will be discussed. Selected synthetic schemes are included to acquaint the reader with the building blocks which are available for the construction of new derivatives, and with the synthetic steps involved. 

In this chapter, we presented our research efforts addressing the first two issues with constrained regularization and intrinsic Raman spectroscopy, respectively. These techniques will play a critical role in prospective studies involving multiple sites/subjects/days. We are currently planning for a multiple-subject and multiple-day in vivo study, first on dogs and then on humans. We believe these new developments together with a robust sample interface will enable us to demonstrate prospective applicability. 

Determination of basal biophysiological parameters may identify subjects with sensitive skin. Earlier studies have shown that increased skin susceptibility has been correlated with an increased basal TEWL, 1 41 skin surface pH,42 and fair skin complexion (measured by chromametric L values),43 whereas no relationship was shown for basal skin thickness, skin blood flow, sebum excretion, and skin hydration.29 However, a recent study by Seidenari et al. utilizing multiple bioengineering techniques showed significant correlations only for capacitance and colorimetric a values.44... 

A number of studies have compared the use of the multiple regression technique using semiempirical parameters such as tt and o-, and parameters calculated for the particular molecules from molecular orbital theory. Hermann, Culp, McMahon, and Marsh (23) studied the relationship between the maximum velocity of acetophenone substrates for a rabbit kidney reductase. These workers were interested in the reaction mechanism, and two types of quantum chemical calculations were made (1) extended Huckel treatment, and (2) complete neglect of differential overlap (CNDO/2). Hydride interaction energy and approaching transition-state energies were calculated from the CNDO/2 treatment. All these parameters plus ir and a values were then subjected to regression analysis. The best results are presented in Table II.
