This authoritative volume focuses on emerging technologies in cancer nano medicine, characterized by their multi-functionality and potential to address simultaneously diverse issues of clinical relevance in the treatment of cancer. The book consists of sixteen chapters divided into six sections: 1) Biological Barriers in Cancer; 2) Tumor Targeting; 3) Targeting the Immune System; 4) Gene Therapy; 5) Nano theranostics and 6) Translational Aspects of Nano-Oncologicals. The volume starts with an introduction describing the biological barriers associated with cancer therapy and highlighting ways to overcome such barriers through the use of nanotechnology. This is followed by an analysis of the two major targeting strategies currently under investigation in cancer therapy: namely, the targeting of cancer cells and the targeting of the immune system. In the first case, the book presents liposomal and polymer-based therapies, including photodynamic approaches. In the second case, it analyzes in detail the possibility of either improving the efficiency of the immune system toward preventing cancer progression (cancer immunomodulation) or generating responses against specific cancer antigens (cancer vaccines).

Beyond these targeting options, "Nano-Oncologicals: New Targeting and Delivery Approaches" presents the most recent technological advances in the area of nucleic acid-based therapies, along with those in the area of theranostics, where the design of multifunctional nano carriers becomes vital. Following the study of the most promising nanotechnologies around the development of nano-oncologicals, the book ends with an overview of regulatory and toxicological issues, which are critical in their translational pathway, and the presentation of a nucleic acid-based therapy case-study. This book is an important resource for scientists interested in the design and development of anticancer nanotechnologies and also to those aiming to push their technology through clinical development.

Development of new-generation vaccines is now more challenging than ever, as identifying, purifying and evaluating vaccine antigens is a complex undertaking. Most importantly, once the relevant antigens have been identified, key focus then shifts to the development of suitable delivery systems and formulations to achieve maximum in vivo potency with minimum potential side effects. These novel formulations-many of which will be nanoparticulates-can deliver the antigens to the desired site, to the relevant antigen presenting cells, and prevent systemic exposure of the immune potentiators. The proposed book will outline all the critical steps that need to be considered for successful development of various types of nanoparticulate delivery systems for vaccine antigens. These contributions from leading experts in the area of vaccine formulation and delivery systems will tie in what is the most current status, including clinical evaluations with these novel vaccine technologies.

This book was conceived from a simple question as to why cancer is so difficult to treat. Ultimately we want to find ways to cure cancers, but that may be an elusive dream at least with the technologies we have now and expect to have in the near future. This leads the question of whether it is possible to improve current cancer treatment methods, especially from the perspective of enhancing targeted drug delivery to tumors. This volume is designed to provide information related to the difficulties in treating cancers through targeted drug delivery, our current understanding of cancer biology, and potential technologies that might be used to achieve enhanced drug delivery to tumors. An ideal drug delivery system for treating cancers would maximize the therapeutic efficacy with minimal side effects in clinical applications. The seemingly improved anticancer efficacy of the current nanoparticle-based formulations needs to be viewed from the context of very poor success rates for translation to human applications. The results of in vitro cell culture models and small animal in vivo experiments have not been extrapolated to clinical applications. Finding the reasons for the lack of successful translation is required if we are to discover approaches to substantially extend the survival time of cancer patients, and hopefully identify cures. Cancer Targeted Drug Delivery: Elusive Dream describes some answers of achieving the so far elusive dream of treating cancers like other chronic diseases with therapies that focus using improved drug delivery systems designed to better align with the unique biological and physiological properties of cancer.

Early anthropological evidence for plant use as medicine is 60,000 years old as reported from the Neanderthal grave in Iraq. The importance of plants as medicine is further supported by archeological evidence from Asia and the Middle East. Today, around 1.4 billion people in South Asia alone have no access to modern health care, and rely instead on traditional medicine to alleviate various symptoms. On a global basis, approximately 50 to 80 thousand plant species are used either natively or as pharmaceutical derivatives for life-threatening conditions that include diabetes, hypertension and cancers. As the demand for plant-based medicine rises, there is an unmet need to investigate the quality, safety and efficacy of these herbals by the "scientific methods". Current research on drug discovery from medicinal plants involves a multifaceted approach combining botanical, phytochemical, analytical, and molecular techniques. For instance, high throughput robotic screens have been developed by industry; it is now possible to carry out 50,000 tests per day in the search for compounds which act on a key enzyme or a subset of receptors. This and other bioassays thus offer hope that one may eventually identify compounds for treating a variety of diseases or conditions. However, drug development from natural products is not without its problems. Frequent challenges encountered include the procurement of raw materials, the selection and implementation of appropriate high-throughput bioassays, and the scaling-up of preparative procedures. Research scientists should therefore arm themselves with the right tools and knowledge in order to harness the vast potentials of plant-based therapeutics. The main objective of Plant and Human Health is to serve as a comprehensive guide for this endeavor. Volume 1 highlights how humans from specific areas or cultures use indigenous plants. Despite technological developments, herbal drugs still occupy a preferential place in a majority of the population in the third world and have slowly taken roots as alternative medicine in the West. The integration of modern science with traditional uses of herbal drugs is important for our understanding of this ethnobotanical relationship. Volume 2 deals with the phytochemical and molecular characterization of herbal medicine. Specifically, It will focus on the secondary metabolic compounds which afford protection against diseases. Lastly, Volume 3 focuses on the physiological mechanisms by which the active ingredients of medicinal plants serve to improve human health. Together this three-volume collection intends to bridge the gap for herbalists, traditional and modern medical practitioners, and students and researchers in botany and horticulture.
