Respiratory System
Chapter 3 Respiratory System Five major disease categories are presented in this chapter: obstructive and restrictive disorders of gas exchange, vascular diseases of the lung, infectious and inflammatory diseases, and…
Diseases of the Male Reproductive System
Chapter 7 Diseases of the Male Reproductive System The male reproductive system develops in close relation with the urinary tract, and the two are usually thought of as the urogenital…
Integumentary System (Skin)
Chapter 9 Integumentary System (Skin) The usual classification of skin diseases differs slightly from the terminology used in general pathology: both the gross appearance of lesions and, at least in…
General Reaction Patterns
Chapter 1 General Reaction Patterns Pathologic anatomy, gross and microscopic, is the science of identifying and interpreting morphologic patterns and relating them to the physiologic and pathologic functions of a…
The New Breadth of Research in the Field
(4.1) Clearly, this model is limited by the size of the data set used. Nevertheless, this model is significant and interesting as it introduces nonlinearity (as log K ow2) into…
Mathematical Treatments and Early Models of Skin Permeability
(3.1) where the terms used are shown in Fig. 3.1. This expression indicates that, at long times, there is a steady-state flux of (A 1 k 12 k 23)/(k 21 + k 23)…
Finite-Dose Models of Transient Exposures and Volatile Formulation Components
Fig. 8.1 Schematic representation of flux and cumulative absorption profiles for a finite-dose application to human skin (© Williams (2003), used with permission) Designing in vitro experiments that accurately reflect this…
Squiggly Lines and Random Dots—You Can Fit Anything with a Nonlinear Model
(7.1) where (7.2)is the permeation coefficient of the lipid fraction of the stratum corneum, (7.3)is the permeation coefficient of the protein fraction of the stratum corneum, and (7.4)where K ow…
Other Approaches to Modelling Percutaneous Absorption
(6.1) where P is the partition coefficient of the permeant between the membrane and the donor vehicle; C is the concentration (in this case, the solubility) of the permeant in…
Algorithms for Estimating Permeability Across Artificial Membranes
(5.1) where J mss is the maximum steady-state flux (μ mol/s/cm2); J mss is the maximum steady-state flux (μ mol/s/cm2); e H is the charge value on a hydrogen with charge higher…
