Book Description
Advanced oxidation processes (AOPs) use chemical treatment to remove contaminants from water by oxidation with hydroxyl radicals. These hydroxyl radicals can be produced using UV light, ozone or hydrogen peroxide, but recently reactions have been developed that use persulfates as the radical source. Persulfates are strong oxidants with flexible in situ activation characteristics, including activation with heat, alkali conditions, electricity, ultrasonic treatment, transition metals, carbon and even organics. Persulfate activation can generate sulfate radicals as well as other reactive species. These reactive species, especially the sulfate radical, can degrade most organic pollutants making them valuable in the fields of water purification, soil remediation, disinfection, sludge dewatering, and other important applications in environmental systems. Describing recent developments in persulfate-based AOPs, this book aims to provide a summary of environmental applications for persulfate-based AOPs and to guide the reader, in a comprehensive way, through various advanced oxidation processes in environmental applications. Topics include new activation methods, activation mechanisms, and advanced materials for use in activating persulfate-based AOPs for different environmental applications.

Book Description
Pathogenic bacteria for human and animals have developed sophisticated weapons, termed virulence factors, to ensure their replication and persistence into their hosts. The authors in this volume show a synthesis on how the various host cellular Rho GTPases activities are manipulated by bacteria to fulfil their virulence.

Book Description
This book considers mainly etiology, pathogenesis, and pathophysiology of aortic aneurysms (AA) and aneurysm rupture and addresses anyone engaged in treatment and prevention of AA. Multiple factors are implicated in AA pathogenesis, and are outlined here in detail by a team of specialist researchers. Initial pathological events in AA involve recruitment and infiltration of leukocytes into the aortic adventitia and media, which are associated with the production of inflammatory cytokines, chemokine, and reactive oxygen species. AA development is characterized by elastin fragmentation. As the aorta dilates due to loss of elastin and attenuation of the media, the arterial wall thickens as a result of remodeling. Collagen synthesis increases during the early stages of aneurysm formation, suggesting a repair process, but resulting in a less distensible vessel. Proteases identified in excess in AA and other aortic diseases include matrix metalloproteinases (MMPs), cathepsins, chymase and others. The elucidation of these issues will identify new targets for prophylactic and therapeutic intervention.

Book Description
The last several years have been a landmark period in the ubiquitin field. The breadth of ubiquitin's roles in cell biology was first sketched, and the importance of ubiquitin-dependent proteolysis as a regulatory mechanism gained general acceptance. The many strands of work that led to this new perception are re counted in this book. A consequence of this progress is that the field has grown dramatically since the first book on ubiquitin was published almost a decade ago [M. Rechsteiner (ed. ), Ubiquitin, Plenum Press, 1988]. In this span, students of the cell cycle, transcription, signal transduction, protein sorting, neuropathology, cancer, virology, and immunology have attempted to chart the role of ubi quit in in their particular experimental systems, and this integration of the field into cell biology as a whole continues at a remarkable pace. We hope that for active researchers in the field as well as for newcomers and those on the fence, this book will prove helpful for its breadth, historical perspective, and practical tips. Structural data are now available on many of the components of the ubiquitin pathway. The structures have provided basic insights into the unusual biochemical mechanisms of ubiquitination and proteasome-mediated proteolysis. Because high-speed computer graphics can convey structures more effectively than print media, we have supplemented the figures of the book with a Worldwide Web site that can display the structures in a flexible, viewer-controlled format.

Book Description
This volume provides summarized scientific evidence of the different classes of plant-derived phytocompounds, their sources, chemical structures, anticancer properties, mechanisms of action, methods of extraction, and their applications in cancer therapy. It also discusses endophyte-derived compounds as chemopreventives to treat various cancer types. In addition, it provides detailed information on the enhanced production of therapeutically valuable anticancer metabolites using biotechnological interventions such as plant cell and tissue culture approaches, including in vitro-, hairy root- and cell-suspension culture; and metabolic engineering of biosynthetic pathways. Anticancer Plants: Natural Products and Biotechnological Implements – Volume 2” explores the natural bioactive compounds isolated from plants as well as fungal endophytes, their chemistry, and preventive effects to reduce the risk of cancer. Moreover, it highlights the genomics/proteomics approaches and biotechnological implementations. Providing solutions to deal with the challenges involved in cancer therapy, the book benefits a wide range of readers including academics, students, and industrial experts working in the area of natural products, medicinal plant chemistry, pharmacology, and biotechnology.
