Mitochondria, often referred to as the “powerhouses” of the cell, generate adenosine triphosphate (ATP) by oxidative phosphorylation or OXPHOS, and maintain cellular homeostasis. In addition to generating ATP, mitochondria are involved in regulation of cell cycle, proliferation, free radical production, innate immune responses and apoptosis. Mitochondrial Function in Lung Health and Disease fills the current gap in the literature and outlines the growing clinical relevance of mitochondrial dysfunction. Currently, there is no overview on the role of mitochondria in pulmonary diseases and this volume focuses on the mitochondrial metabolism, redox signaling, and mechanisms of mitochondrial pathways in lung injury, inflammation, repair and remodeling. Furthermore, in addition to their well-recognized role in cellular energy production and apoptosis, mitochondria appear to play a role in many respiratory diseases and lung cancer. Chapters are written by top notch researchers and clinicians and outline the evidence for mitochondrial biogenesis in inhalational lung injury, COPD and asthma.

Even though initially considered as a passive means for storing energy, lipids are now regarded as multifaceted molecules with crucial structural and functional activities. For instance, some of them play essential roles as key components of cell membranes whereas others act as signaling molecules in the regulation of cell homeostasis. In recent years, lipid research has attracted increasing interest because of the involvement of this class of compounds in human health. Indeed, a plethora of pathological conditions are characterized by alterations in lipid metabolism, such as cardiovascular diseases and brain disorders. This Special Issue is a collection of papers from different experts in lipid research, with the aim of providing new insights into the physiopathological involvement of lipids and their impact on human health. This collection also demonstrates the usefulness of interdisciplinary approaches in the development of novel methods to study and manipulate lipid metabolism, which may represent an attractive target for designing effective therapeutic strategies to counteract numerous pathologies.
In the past few years there has been the increased recognition that the effects of oxidative stress are not limited to the damage of cellular constituents. There is now evidence that reactive oxygen species (ROS) can alter cell function by acting upon the intermediates, or second messengers, in signal transductions. Such effects on signaling mechanisms probably account for the role of oxidative stress in inflammation, aging, and cancer. This volume brings together internationally recognized researchers in both the major areas covered by the book, oxidative stress and signal transduction. The work is organized in three sections. The first deals with the immediate cellular responses to oxidative stress and the production of second messengers. The second details the connection between second messengers and the gene. The third part looks more closely at the level of the gene.
Incidences of inflammatory airway diseases are on the rise across the world. Existing therapeutic options are ineffective, unsafe, and expensive, and severe cases are nonresponsive to conventional therapy. Therefore, it is imperative that research be undertaken to discover new treatment options. Obstructive Airway Diseases: Role of Lipid Mediators discusses clinically successful and potential lipid targets that can make a difference in treating some of the most intractable disease states. Topics discussed include: Obstructive airway diseases, etiology, pathophysiology, and existing therapeutic options What constitutes a lipid and how it is broken down to generate biologically active mediator...

Covers endothelial biology from the fundamentals of structure and lung fluid balance physiology to descriptions of the molecular mechanisms involved in the development of lung failure. This illustrated text provides the knowledge of endothelial function, vascular integrity, pulmonary function, and pathophysiology in respiratory failure.
This comprehensive volume on the blood-gas barrier (BGB) among vertebrates covers its structure and composition along with aspects of evolution, bioengineering, and morphometry. The book also discusses the embryological development of the BGB, including chronology of events and molecular control in vertebrates; modulation of the barrier function, including cyclic stretch-induced increases in alveolar epithelial permeability; mechanisms of lung vascular/epithelial permeability; transport mechanisms of the BGB, including sodium transport channels; factors affecting trans-barrier traffic of fluids, such as chronic elevation of pulmonary microvascular pressure; stress failure; regulation and rep...
