This book addresses the issues relating to a wide variety of ocular diseases from which millions of people suffer. Long-term challenges include visual impairment and ocular blindness. Certain ocular diseases are quite rare, whereas others, such as cataracts, age-related macular degeneration (AMD), and glaucoma, are very common, especially in the aging population. A rapid expansion of new technologies in ocular drug delivery and new drug candidates, including biologics, to treat these challenging diseases in the retina and posterior segments of the eye have recently emerged. These approaches are necessary because the eye has many unique barriers to drug delivery. Thus, this timely reference Drug Delivery for the Retina and Posterior Segment Disease compiles and analyzes recent advances in the research and development of drug delivery systems for retina and posterior segment diseases of the eye, with an emphasis on the use of implantable devices, iontophoresis as well as micro- and nanoparticles.

This book reviews the central role of hypoxia in cancer initiation and progression. It discusses the mechanisms of hypoxia in chemoresistance, radioresistance, angiogenesis, vasculogenesis, metastasis, metabolic, and genomic instability. It also explores the potential of hypoxia in the diagnosis and treatment of cancer. The book provides an overview of hypoxia imaging, its biological relevance, and mechanism of action. It helps in understanding the molecular mechanisms of the regulation of senescence by hypoxia. It explores the contribution of hypoxia to immune resistance and immune suppression/tolerance and determines the hypoxia-responsive long non-coding RNAs in regulating hypoxic gene expression at chromatin, transcriptional, and post-transcriptional levels. Further, it presents the functional link between hypoxia and miRNA expressions and hypoxia-regulated miRNAs in cancer cell survival in a low oxygen environment. Lastly, it discusses the applications of tumor-on-a-chip technology for the understanding of hypoxia-tumor microenvironment. This book is a valuable source for oncologists and scientists working to understand the role of hypoxia in cancer and therapeutic approaches.
