With contributions from an international team of pioneers and experts in dendrimer research, this book provides a comprehensive overview of the latest research efforts in designing and optimizing dendrimer-based drug delivery systems. The book analyzes key issues, demonstrating the critical connections that link fundamental concepts, design, synthesis, analytical methodology, and biological assessment to the practical use of dendrimers in drug delivery applications. Topics covered include: Dendrimer history Synthesis Physicochemical properties Principles of drug delivery Applications in diverse biomedical fields Dendrimer-Based Drug Delivery Systems reflects the authors' thorough review and analysis of the current literature as well as their own firsthand experience in the lab. Readers will not only discover the current state of the science, but also gain valuable insights into fruitful directions for future research. References at the end of each chapter serve as a gateway to the growing body of literature in the field, enabling readers to explore each individual topic in greater depth. Pharmaceutical and biomedical researchers will find this book a unique and essential guide to the opportunities, issues, and challenges involved in fully exploiting the potential of dendrimers to improve drug delivery.
RNA interference (RNAi) is a process in living cells whereby small double stranded RNA interferes with the expression of specific genes with complementary nucleotide sequence. Like many nucleic acid-based therapies, RNAi has great potential in treating various life-threatening diseases. However, the poor stability and cellular uptake of RNAi molecules remain considerable barriers to their efficient delivery which is paramount to a successful therapy. This book provides a comprehensive introduction to RNAi delivery, then goes on to discuss different delivery strategies, and concludes with current applications in various diseases. It covers: Mechanisms, Barriers, and Analysis of RNAi Delivery Nonclinical Safety Assessments and Clinical Pharmacokinetics: A Regulatory Perspective Bioconjugation of siRNA for Site Specifi c Delivery Nanoscale Delivery Systems for RNAi Environmentally-Responsive Delivery Systems for RNAi Light-sensitive RNAi Viral-Mediated Delivery of shRNA and miRNA RNAi applications in Cancer Therapy, Liver Diseases, Hepatitis B, and Ocular Disease miRNA as therapeutic agents and targets Advanced Delivery and Therapeutic Applications of RNAi combines the essential aspects of developing RNAi therapeutics from bench to clinic, and is invaluable for researchers working on RNAi, drug discovery and delivery, biomedical engineering, biomaterials, molecular biology, and biotechnology.
This paper investigates how institutional and macroeconomic factors influence the profit efficiency frontier of Russian banks. We demonstrate that the macroeconomic environment is crucial for constructing the profit frontier. The cargo transportation index, exchange rate, and intermediation ratio have a positive relationship with this efficiency frontier while the share of loan loss provision in the loan portfolio is negatively associated with it. In addition, we find that such institutional determinants as a bank’s location, branch network diversity, and ownership type matter for constructing this frontier.
Steroid dimers are an important group of compounds produced by various marine organisms, and also synthesized in the laboratories. This group of compounds possesses various pharmacological and biological properties, and can also be used to create “molecular umbrellas” for drug delivery.
