Book Synopsis Morphometry of the Human Lung by : Ewald R. Weibel
Download or read book Morphometry of the Human Lung written by Ewald R. Weibel and published by Academic Press. This book was released on 2013-10-22 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: Morphometry of the Human Lung considers the developments in understanding the quantitative anatomy of the lung, and in the correlation of anatomy with physiology. This book is composed of 11 chapters, and begins with an overview of a systematic approach to a quantitative morphologic analysis of the architecture of the human lung, followed by a presentation of general problems of methodology and the derivation of reliable dimensional models of this organ. The subsequent chapters describe the methods of preparation of tissues, methods of random sampling, and adaptation of methodologies from other fields of science. These topics are followed by discussions the mathematical formulations for the translation of the data into the desired geometric forms and a technique of counting. The final chapters look into the mode of distribution and geometric forms that should eventually facilitate mathematical and physical considerations regarding the function of the lungs. These chapters also consider the application of these quantitative methods to the study of pathologic specimens, providing a most timely renovation of morphologic pathology. This book will be of value to pulmonologists, physiologists, and researchers who are interested in lung morphometry.

Book Synopsis Numerical Modeling of PO-218 Deposition in a Physiologically Realistic Lung Bifurcation Model by : Khalid Ahmad Mously
Download or read book Numerical Modeling of PO-218 Deposition in a Physiologically Realistic Lung Bifurcation Model written by Khalid Ahmad Mously and published by . This book was released on 1997 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: Experimental data for lung bifurcations reveals complex geometries and distinct asymmetrical characteristic, which affects the localized distribution of particles deposited in the lung. This study is based on recently published numerical results for a symmetric physiological realistic bifurcation geometry Heistracher and Hofmann (1995) which has been extended here to the case of a asymmetric geometry. The asymmetric PRB model was used to study the flow field and the deposition of ultrafine particles for inspiratory and expiratory conditions. In the present study, we investigated the effect of different flow rates, representing human activity and deposition of different ultrafine particles representing radon daughter (Po-218), in the PRB model. Numerical results were compared with the limited available experimental and numerical data. The fluid dynamic computer program FIDAP was used for this purpose.

Book Synopsis Pulmonary Drug Delivery by : Ali Nokhodchi
Download or read book Pulmonary Drug Delivery written by Ali Nokhodchi and published by John Wiley & Sons. This book was released on 2015-08-03 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: Drug therapy via inhalation route is at the cutting edge of modern drug delivery research. There has been significant progress on the understanding of drug therapy via inhalation products. However, there are still problems associated with their formulation design, including the interaction between the active pharmaceutical ingredient(s) (APIs), excipients and devices. This book seeks to cover some of the most pertinent issues and challenges of such formulation design associated with industrial production and desirable clinical outcome. The chapter topics have been selected with a view to integrating the factors that require consideration in the selection and design of device and formulation components which impact upon patient usability and clinical effectiveness. The challenges involved with the delivery of macromolecules by inhalation to both adult and pediatric patients are also covered. Written by leading international experts from both academia and industry, the book will help readers (formulation design scientists, researchers and post-graduate and specialized undergraduate students) develop a deep understanding of key aspects of inhalation formulations as well as detail ongoing challenges and advances associated with their development.

Book Synopsis Particle Deposition in Replica Healthy and Emphysematous Alveolar Models Using Computational Fluid Dynamics by : Edward M. Harding
Download or read book Particle Deposition in Replica Healthy and Emphysematous Alveolar Models Using Computational Fluid Dynamics written by Edward M. Harding and published by . This book was released on 2010 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Particle deposition in the pulmonary region of the lung has gained increasing interest in the past years. Of particular interest are nano-sized particles, because they have the potential of crossing the blood-gas barrier and into the capillaries. Many factors contribute to how and where particles deposit, such as lung morphology, breathing conditions, fluid flow characteristics, and alveolar wall movement. These many factors make simulating particle deposition in the alveoli difficult. The experimental in vivo studies have commonly used micron sized particles and there is a lack of data for smaller sized particles. Due to these many factors, deposition in the pulmonary region is not well understood. Furthermore, little attention has been paid to the emphysematous lungs, which have characteristics quite different than the healthy lung. In this work, healthy and emphysematous replica acinus models were created from human lung casts using a 3D reconstruction software package. The models were used for simulating the particle deposition due to diffusion using Fine Particle Model (FPM). The FPM program was validated against an analytical solution using a straight tube, before moving on to predict the deposition in the alveolar models. Two particle sizes, 1 and 3 nm, were used to understand and compare pure diffusion in the lung using concentration contours. Results showed the particle deposition rate (particles/s) to be higher in the emphysemic. However, deposition rate per area (particles/m2s) was found to be higher in the healthy model. The deposition efficiency (% of particles that deposit) of the healthy model was greater than the emphysemic model, consistent with literature. Results were found to be lower than experimental in vivo measurements and whole lung model of local alveolar deposition (particles deposited in alveoli/particles entering alveoli) in comparison to our results in the pulmonary region, showing the importance of including axial diffusion effects. More work must be done experimentally and numerically before an understanding of deposition of particles of this size can be determined."--Abstract.
