Cell death is critical for embryo development and body growth. Several types of cell death have been discovered. The dysfunction of cell death is responsible for various diseases; however, the mechanism underlying cell death is not fully elucidated. Recent advances in cell death research have led to improved diagnosis, treatment, and clinical management of diverse diseases; however, novel therapeutic strategies are urgently needed. This book presents the most recent advances in cell death and related diseases.

Tumor angiogenesis is critical for tumor growth and progression. It is a multistep and complicated process, and the mechanism underlying tumor angiogenesis is not fully elucidated. Recent advances in tumor angiogenesis research have led to improved diagnosis, drug treatment, and clinical management of cancer. However, novel strategies for cancer treatment are urgently needed, especially biomarker discovery for diagnosis, prognosis, and targeted therapy. This book presents the most recent advances in tumor angiogenesis.

This brief guides the reader through three basic Internet resource pricing models using an Internet cost analysis. Addressing the evolution of service types, it presents several corresponding mechanisms which can ensure pricing implementation and resource allocation. The authors discuss utility optimization of network pricing methods in economics and underline two classes of pricing methods including system optimization and entities' strategic optimization. The brief closes with two examples of the newly proposed pricing strategy helping to solve the profit distribution problem brought by P2P free-riding and improve the pricing efficiency with the introduction of the price discrimination. The Internet resource pricing strategy is not only the key factor of Internet resource allocation efficiency, but also the determinant of the profit. The methods and models discussed in Internet Resource Pricing Models increase the efficiency of existing pricing strategies to ensure a sound and sustainable development of the Internet. The brief will help researchers and professionals working with this key factor of Internet resource allocation.

The development of technologies that allow targeting of specific cells has progressed substantially in recent years for several types of vectors, particularly viral vectors, which have been used in 70% of gene therapy clinical trials. Particular viruses have been selected as gene delivery vehicles because of their capacities to carry foreign genes and their ability to efficiently deliver these genes associated with efficient gene expression. This book is designed to present the most recent advances in viral gene therapy

Surprisingly, the conduction velocity in shrimp nerve is the fastest among all nerve fibers in the animal kingdom. In this volume, readers will find a description of both the origin and mechanisms of nerve impulse conduction in shrimp.
