This handbook covers Optical Coherence Tomography Angiography (OCT-A) with a specific focus on choroidal and vitreoretinal disorders. It serves as an invaluable resource for teaching and aiding daily clinical decision-making in the field. Book chapters dissect the fundamentals of angiography through OCT, offering guidance on OCT-A and insights into macular perfusional findings across various vitreoretinal and choroidal pathologies. From diabetic retinopathy to autoimmune diseases and neovascularization, the book addresses prevalent vascular entities encountered in routine practice. Furthermore, it explores innovative approaches, including antivascular endothelial growth factor molecules and extended-release delivery devices, contributing significantly to the diagnostic and decision-making processes in clinical and surgical retina care. Each chapter is contributed by experts in the relevant subspecialty. Key Features: Practical, patient-centered guide emphasizing a clinical approach. Demonstrative clinical cases for enhanced understanding. Evaluation of perfusional indices using noninvasive and noncontact imaging techniques. High histopathological correlation of structural tissue characterization with microvascular evaluation. Exploration of new perfusion concepts and their role in disease pathogenesis. Part 1 of the book focuses on OCT-A principles and applications in ophthalmology. It covers the basics of OCT-A, its contributions to eye disease study and treatment, and a comparative analysis with OCT for choroidal and vitreoretinal diseases. Additional information on nomenclature, normative datasets, and data analysis, presenting indices in different eye conditions is also presented. The emphasis is on macular perfusion in surgically resolved myopic foveoretinal detachment, postoperative evaluation in retinal detachment, and long-term analysis in diabetic retinopathy.

Gastrointestinal cancer is one of the most prevalent causes of cancer-related deaths in the world. Recent research demonstrates that phytochemicals are critical in preventing and managing gastrointestinal cancer. The increased intake of phytochemicals could reduce the risk of cancer by inhibiting cancer cell proliferation, inducing apoptosis and autophagy, and suppressing angiogenesis as well as cancer cell metastasis. These mechanisms are also known to counter Helicobacter pylori infection and modulate gut microbiota. There is preliminary data suggesting that daily supplementation with high doses of certain vitamins combined with conventional therapeutic agents may enhance their growth inhibitory effects on tumor cells and protect normal tissues against some of their toxic effects. This book attempts to fill gaps on the role of phytonutrients in the treatment of cancer in the gastrointestinal tract (GIT). It discusses the action of individual vitamins on cellular and molecular parameters and describes how vitamins inhibit protein kinase C activity, increase the production of certain growth factors, and modulate the expression of a number of oncogenes. The book is divided into 2 parts. The first part summarizes the pathophysiology of GIT cancers and introduces readers to anticancer phytonutrients. A chapter on the status of FDA approved nutraceuticals rounds up this section. The second part of the book provides a systematic review on the different plant derived chemicals that can be used to treat GIT cancer. Each chapter in this section focuses on a specific type of phytochemical agent and its molecular mechanisms relevant to the disease. This book will give the reader a holistic view of gastrointestinal cancer treatment and the value of natural compounds in developing functional food and drugs for preventive medicine.

Inflammation triggers specific metabolic pathways and if not resolved, translates into several painful diseases such as rheumatoid arthritis, lupus, Alzheimer's disease, cardiovascular disorders and psoriasis. Various processes have been explored to understand the factors behind inflammation and consequently, many mechanisms have been examined to suppress it. The nucleotide-binding domain like receptor 3 (NLRP3) inflammasome is an example of such factors which is responsible for triggering sterile and microbe induced inflammation. Studies of genetic variants of the related gene have revealed insights into the mRNA expression pathways that may help researchers to identify crucial disease mechanisms. This book is a review of the scientific findings of distinguished scholars who have studied NLRP3 inflammasome activation and its contribution in worsening the outcomes of inflammatory disorders. This collection of chapters covers many aspects of the multifaceted role of NLRP3 inflammasome. Beginning with airway inflammation and fibrosis, it progresses to explore its involvement in pulmonary hypertension, heart diseases, tuberculosis, cardiovascular complications, and childhood asthma. Additionally, it examines the inflammasome's impact on protozoan parasitic infections and neuropathic pain. The chapters not only elucidate the intricate mechanisms of NLRP3 activation but also discuss potential inhibitors and therapeutic targets. Readers will gain a comprehensive understanding of the NLRP3 inflammasome's diverse implications across different physiological contexts. The book includes references making this book a valuable treatise of insights for researchers, clinicians, and healthcare professionals.
