Photodynamic Therapy

Photodynamic Therapy: From Theory to Application brings attention to an exceptional treatment strategy, which until now has not achieved the recognition and breadth of applications it deserves. The authors, all experts and pioneers in their field, discuss the history and basic principles of PDT, as well as the fundamentals of the theory, methods, and instrumentation of clinical diagnosis and treatment of cancer. Non-oncological applications such as the use of PDT in control of parasites and noxious insects are also discussed. This book serves as a standard reference for researchers and students at all levels, clinical specialists interested in the topic and those in industry exploring new areas for development. A comprehensive exposition of both the theory and application of PDT, this book fills the gaps in the current literature by bringing together both basic understanding of the process of PDT and an expanded vision of its applications.

Photodynamic Therapy (PDT) has become an important treatment modality in medical practice. New and exciting applications continue to emerge and the future of PDT looks brighter and brighter. Dermatologists and other health professionals around the world rely on its therapeutic effect for the treatment of actinic keratoses, non-melanoma skin cancers, acne vulgaris, and various other dermatologic conditions. In this comprehensive yet concise book, world-renowned experts showcase all of the common, everyday uses of PDT in dermatologic offices. They also examine how this beneficial therapy can be utilized to its full capacity. The considerable knowledge presented here renders this publication an indispensable resource for all dermatologists and health professionals who offer their patients this effective, noninvasive procedure.

As a new concept of cancer treatment, photodynamic therapy (PDT) has gained great attention in the last few decades. Compared to classical treatments such as surgery, chemotherapy and radiotherapy, PDT is a noninvasive, localized treatment of lesions that shows fewer side effects and has low systemic toxicity. In Chapter One, the basic mechanisms, applications and functional nanomaterials-based drug delivery systems for photodynamic therapy of cancer are reviewed. Chapter Two summarizes the application of different carbon based nanomaterials as agents for PDT and discusses current state-of-the-art use of fullerenes and their derivatives, carbon nanotubes and graphene quantum dots in PDT. Chapter Three covers the benefits and pitfalls of using chemi- and bioluminescent systems as intracellular excitation sources in PDT. Bioluminescence is a widespread natural phenomenon, which consists on emission of light resulting from the oxidation of a substrate in a reaction catalyzed by an enzyme in a biological system. Chapter Four addresses in the synthesis, characterization, and photodynamic activity of a novel hydrophobic photosensitizer 5,10,15,20-tetrakis(benzo[b]thiophene) Porphyrin (BTP) and water soluble photosensitizer 5,10,15,20-Tetrakis(7- sulfonatobenzo[b]thiophene) Porphyrin (SBTP). The authors lab is engaged in the synthesis of PDT molecules incorporating benzothiophene moiety to the meso-position of porphyrin molecules. Chapter Five discusses the Guidelines for Gastroenterological Endoscopy in Patients on Oral Antithrombotic Treatment established by the Japan Gastroenterological Endoscopy Society (JGES).These guidelines classify endoscopic interventions according to the risk of hemorrhage and specify the management of various antithrombotic drugs. Endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD) are classified as high-risk procedures for hemorrhage, but PDT is not included in the guidelines. Because PDT causes ischemic necrosis of tumor tissue, the authors say this could possibly be performed safely in patients on oral antithrombotic therapy. The authors of Chapter Six developed a method of the initial concentration of protoporphyrin-IX in the operated removing glioblastoma tissue using the calibration curve of the fluorescent intensity and the known Pp-IX concentration in order to estimate of the more correlated with the cure rate.

Photodynamic therapy is a proven effective treatment of actinically damaged skin cells, nonmelanoma skin cancers, and acne and other pilosebaceous conditions. As an agent for general facial rejuvenatin it has untapped potential. The current state of PDT therapy and future applications are discussed in detail in this exciting new volume. Throughout, the focus is on evidence-based clinical uses of PDT, including pretreatment regimens, avoidance and management of complications, and posttreatment suggestions.

With today's focus on targeted and minimally invasive therapies, photodynamic therapy (PDT) is now being studied and used to combat many disease states and to investigate critical biological questions. This groundbreaking resource brings you the latest advances in photodynamic therapy and offers you a solid understanding of the design, delivery and dosimetry of the three basic ingredients of PDT - photosensitizers, light and oxygen. The book covers novel areas of mechanistic and innovative translational approaches. Moreover, it gives you an overview of the important medical applications of PDT, including approved treatments, clinical trials, and investigated therapies for cancer and non-malignant diseases.

Photodynamic therapy (PDT) is a ground breaking medical technique which uses lasers to activate light-sensitive chemicals to treat cancer and other diseases without resorting to surgery. For the first time, Chemical Aspects of Photodynamic Therapy introduces in an accessible way the physics, chemistry and biology behind the technique. This highly a

This book covers the broad field of cellular, molecular, preclinical, and clinical imaging either associated with or combined with photodynamic therapy (PDT). It showcases how this approach is used clinically for cancer, infections, and diseases characterized by unwanted tissue such as atherosclerosis or blindness. Because the photosensitizers are also fluorescent, the book also addresses various imaging systems such as confocal microscopy and small animal imaging systems, and highlights how they have been used to follow and optimize treatment, and to answer important mechanistic questions. Chapters also discuss how imaging has made important contributions to clinical outcomes in skin, bladder, and brain cancers, as well as in the development of theranostic agents for detection and treatment of disease. This book provides a resource for physicians and research scientists in cell biology, microscopy, optics, molecular imaging, oncology, and drug discovery.

Written by recognised experts, Photodynamic Therapy provides a comprehensive explanation of what PDT is and how it has developed as a technique.
