Download or read book Aerosols and the Lung written by Stewart W. Clarke and published by Elsevier. This book was released on 2015-08-11 with total page 291 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aerosols and the Lung covers all aspects of aerosols and the lung, including the use of aerosol in clinical medicine. This volume was developed from the editors' longstanding interest in lung defenses coupled with the radioaerosol technique of assessing their efficiency. This book is organized into 11 chapters. The coverage of these chapters include the physical properties of aerosol required to evaluate their inhalation into the lung, production of aerosol that is suitable for inhalation, determination of aerosol deposition in the lungs and the assessment of lung clearance. This book also highlights the importance of radioaerosols in estimating airway calibre, in detecting airway disease and in ventilation imaging. This book will be of interest to medical students and professionals, particularly those dealing with studies of the human lungs and aerosols.

Available in PDF, EPUB and Kindle. Book excerpt: Significant fractions of airborne particles composing inhaled aerosols can deposit along the respiratory tract during breathing. Depending on the environmental condition, some particles that enter the body via the respiratory route can pose health hazards. On earth, three general rate mechanisms are active in this deposition process: (1) inertial impaction; (2) diffusion; and (3) gravity-dependent sedimentation. Space craft, stations, and bases represent unique settings where potentially pathogenic aerosols may be encountered under the unique condition of zero or reduced gravity. The present study was undertaken in order to predict how particle deposition in the human respiratory tract at zero gravity may differ from that on earth. We employed the aerosol deposition model of the Task Group on Lung Dynamics to assess the regional deposition of particles ranging from 0.01 to 10 .mu.m diameter at two particulate densities, 1 and 4, during simulated tidal breathing and breathing during moderate - heavy exercise. Our results suggest the gas exchange regions of the lungs of space travelers and residents are afforded some protection, relative to their earth-bound counterparts, against the deposition of particles due to the absence of gravity; and approximately 2 to 10 fold reduction in the efficiency of collection of particles> 0.5 .mu.m in diameter occurred in the pulmonary region during resting conditions and exercise. Deposition along the tracheobronchial tree, however, is not markedly altered in the absence of gravity, indicating airway sites contributing to this structure remain susceptible to insults by inhaled aerosols. 18 references, 2 figures, 2 tables.

Book excerpt: "The combination of scientific and institutional integrity represented by this book is unusual. It should be a model for future endeavors to help quantify environmental risk as a basis for good decisionmaking." â€"William D. Ruckelshaus, from the foreword. This volume, prepared under the auspices of the Health Effects Institute, an independent research organization created and funded jointly by the Environmental Protection Agency and the automobile industry, brings together experts on atmospheric exposure and on the biological effects of toxic substances to examine what is knownâ€"and not knownâ€"about the human health risks of automotive emissions.

This book was released on 2007 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: The environment surrounding us is composed of aerosol particles, which can be radioactive, allergic, or therapeutic in nature. Toxic particles when deposited on the respiratory tract may lead to the pathogenesis of lung disease. On the other hand, therapeutic aerosols are used for many respiratory diseases. Moreover, long term space travel and associated risk of inhaling hazardous nonterrestrial aerosol have made it significant to study the impact of gravity on particle deposition. Accurate deposition prediction is prerequisite for both toxicity measurement and drug delivery. Lung deposition of aerosols may be a very sensitive time dependent phenomenon. So to capture the true effect of time-dependency and to predict the transient local deposition, functions based on instantaneous deposition rate are required. An attractive alternative is to develop a numerical scheme that gives a better agreement with experiments using the existing functions. In the present study two such schemes will be described and implemented in an Eulerian deposition model (TECHAero) to predict some practical cases.

This book was released on 2006-09-07 with total page 87 pages. Available in PDF, EPUB and Kindle. Book excerpt: The National Institute of Allergy and Infectious Diseases (NIAID) gives the highest priority to developing countermeasures against bioterrorism agents that are highly infective when dispersed in aerosol form. Developing drugs to prevent or treat illnesses caused by bioterrorism agents requires testing their effectiveness in animals since human clinical trials would be unethical. At the request of NIAID, the National Academies conducted a study to examine how such testing could be improved. Overcoming Challenges to Develop Countermeasures Against Aerosolized Bioterrorism Agents provides recommendations to researchers on selecting the kinds of animal models, aerosol generators, and bioterrorism agent doses that would produce conditions that most closely mimic the disease process in humans. It also urges researchers to fully document experimental parameters in the literature so that studies can be reproduced and compared. The book recommends that all unclassified data on bioterrorism agent studies-including unclassified, unpublished data from U.S. Army Medical Research Institute of Infectious Diseases (USAMRIID)-be published in the open literature. The book also calls on the U.S. Food and Drug Administration to improve the process by which bioterrorism countermeasures are approved based on the results of animal studies.

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.
