Book Description
The new frontier of pharmaceutical sciences is gene therapy, which is the use of molecules able to interact directly with the expression of the genetic material of the patient as well as of the disease-causing guest (bacteria, virus, parasites, and tumor cells). Among the molecules of interest for gene therapy, a relevant role is played by small interfering RNA (siRNA) molecules able to interfere with the expression of genes of interest for some diseases. However, siRNA molecules, even if they are powerful as drugs, are difficult to deliver since they are sensitive to enzymes present in plasma and they are large and negatively charged, so are difficult to administer into the cell nuclei, since the cell walls are scarcely permeable to large molecules and are also negatively charged. Therefore, the focus of research on siRNA-based therapies is their delivery, which can be performed by chemical modification, association with aptamers or polycations, or embedding them into properly designed liposomes. This book is centered on the more recent development in siRNA delivery techniques toward the clinical applications of this potent class of drugs.

Book Description
In the past few decades there has been incredible growth in "bionano"-related research, which has been accompanied by numerous publications in this field. Although various compilations address topics related to deoxyribonucleic acid (DNA) and protein, there are few books that focus on determining the structure of ribonucleic acid (RNA) and using RNA as building blocks to construct nanoarchitectures for biomedical and healthcare applications. RNA Nanotechnology is a comprehensive volume that details both the traditional approaches and the latest developments in the field of RNA-related technology. This book targets a wide audience: a broad introduction provides a solid academic background for students, researchers, and scientists who are unfamiliar with the subject, while the in-depth descriptions and discussions are useful for advanced professionals. The book opens with reviews on the basic aspects of RNA biology, computational approaches for predicting RNA structures, and traditional and emerging experimental approaches for probing RNA structures. This section is followed by explorations of the latest research and discoveries in RNA nanotechnology, including the design and construction of RNA-based nanostructures. The final segment of the book includes descriptions and discussions of the potential biological and therapeutic applications of small RNA molecules, such as small/short interfering RNAs (siRNAs), microRNAs (miRNAs), RNA aptamers, and ribozymes.

Book Description
Advanced Drug Delivery Systems in the Management of Cancer discusses recent developments in nanomedicine and nano-based drug delivery systems used in the treatment of cancers affecting the blood, lungs, brain, and kidneys. The research presented in this book includes international collaborations in the area of novel drug delivery for the treatment of cancer. Cancer therapy remains one of the greatest challenges in modern medicine, as successful treatment requires the elimination of malignant cells that are closely related to normal cells within the body. Advanced drug delivery systems are carriers for a wide range of pharmacotherapies used in many applications, including cancer treatment. The use of such carrier systems in cancer treatment is growing rapidly as they help overcome the limitations associated with conventional drug delivery systems. Some of the conventional limitations that these advanced drug delivery systems help overcome include nonspecific targeting, systemic toxicity, poor oral bioavailability, reduced efficacy, and low therapeutic index. This book begins with a brief introduction to cancer biology. This is followed by an overview of the current landscape in pharmacotherapy for the cancer management. The need for advanced drug delivery systems in oncology and cancer treatment is established, and the systems that can be used for several specific cancers are discussed. Several chapters of the book are devoted to discussing the latest technologies and advances in nanotechnology. These include practical solutions on how to design a more effective nanocarrier for the drugs used in cancer therapeutics. Each chapter is written with the goal of informing readers about the latest advancements in drug delivery system technologies while reinforcing understanding through various detailed tables, figures, and illustrations. Advanced Drug Delivery Systems in the Management of Cancer is a valuable resource for anyone working in the fields of cancer biology and drug delivery, whether in academia, research, or industry. The book will be especially useful for researchers in drug formulation and drug delivery as well as for biological and translational researchers working in the field of cancer.

Book Description
The use of nanotechnology in pharmaceutical development has progressed significantly in recent decades. This rapid advancement is driven by crucial need for improving the performance of present diagnostic and therapeutic modalities, as well as development of a new class of delivery systems for complex entities such as genes and proteins. Nanocarriers currently in use for the delivery of drugs and genetic materials can be generally divided to two categories: those made from lipids and those made from synthetic or natural polymers. Although lipid-based carriers are generally regarded to be safe and efficient, they do not possess sufficient chemical flexibility to fit individual requirements in delivery. In this thesis, we have explored lipid-substitution of three different polymer-based nanocarriers as means to develop optimum structures for drug as well as siRNA delivery. For the delivery of a potent amphiphilic antifungal drug, amphotericin B (AmB), lipid modification (particularly cholesteryl modification) of the core structure in poly(ethylene oxide)-poly(caprolactone) micelles was proved to be efficient in enhancing the solubility while reducing the hemolytic activity of encapsulated AmB. On the other hand, lipid modification of low molecular weight (2 kDa) polyethyleneimine (PEI2) has enhanced the properties of the nanocarriers in the delivery of STAT3-siRNA in wild type and resistant breast cancer cell models leading to an improved anti-cancer efficacy in combination with chemotherapeutic drugs, i.e. DOX and PTX. Finally, cholesteryl modification of poly(ethylene oxide)-poly(caprolactone-g-spermine) enhanced the properties of these nanocarriers for in vivo delivery of siRNA. This modification enhanced the stability, safety and cellular uptake of complexed siRNA leading to better silencing activity at the mRNA level. Overall, our results pointed to the positive impact of lipid modification in enhancing the properties of polymeric nanocarriers leading to viable formulations for effective delivery of AmB and siRNA therapeutics.
