DOWNLOAD EBOOKIn joint replacement surgery with suboptimal bone, allograft materials are often used to achieve biological fixation of the metallic implant to the host bone and reducing the implant fixation time. The most commonly used techniques are cemented and hydroxyapatite (HA)-coated metallic implants. Typically, HA coatings are suggested for patients with better bone stock, whereas recommended implant fixation process for most other osteoporotic patients is bone cements. In general, there is a long-standing need to improve the performance of hip and other devices for longer in vivo implant lifetime that can help in reducing the number of revision surgeries, as well as minimizing physical and mental trauma to the patient. To achieve these goals, it is important to understand the mechanical and biological properties of coatings that can influence not only its short- and long-term bioactivity but also life span in vivo. Over the years, it has been recognized that the stability of a coated implant is governed by its physical and mechanical properties. A coating that separates from the implant provides no advantage over an uncoated implant and undesirable due to problems with debris materials, which can lead to osteolysis. Therefore, it is important to properly characterize the coated implants in terms of its physical and mechanical properties. In this chapter, specific details on coating characterization techniques including sample dimensions, sample preparation, experimental procedure and data interpretation are discussed. In particular, the standards and requirements of regulatory organizations are presented elucidating the significance and use of each characterization. It is important to appreciate that mechanical properties of coatings can only be determined with certain coating specification such as coating thickness. This chapter is designed even for non-experts to follow mechanical property characterizations of coatings on medical implants.

DOWNLOAD EBOOKCoatings based on hydroxyapatite and calcium phosphates have a significant relevance in several research fields, such as biomaterials, cultural heritage, and water treatment, due to their characteristic properties. Hydroxyapatite can easily accommodate foreign ions, which can either be incorporated into the lattice, thanks to its specific lattice characteristics, or be adsorbed onto its surface. All these substitutions significantly alter the morphology, lattice parameters, and crystallinity of hydroxyapatite so they influence its main properties. These ion substitutions can be sought or can derive from substrate contaminations, which is an important aspect to be evaluated. Finally, this capability can be used to obtain hydroxyapatites with specific properties, such as antibacterial characteristics, among others. For these reasons, the aim of this Special Issue is to document current advances in the field of ion-substituted hydroxyapatites and highlight possible future perspectives regarding their use. Contributions in the form of original articles and review articles are presented, covering different areas of application.

DOWNLOAD EBOOKThis book introduces several remarkable new probabilistic objects that combine spatial motion with a continuous branching phenomenon and are closely related to certain semilinear partial differential equations (PDE). The Brownian snake approach is used to give a powerful representation of superprocesses and also to investigate connections between superprocesses and PDEs. These are notable because almost every important probabilistic question corresponds to a significant analytic problem.

DOWNLOAD EBOOKThis two-part multivolume set provides a comprehensive overview of current achievements in biomedical applications of nanotechnology, including stem cell based regenerative medicine, medical imaging, cell targeting, drug delivery, and photothermal/photodynamic cancer therapy. New approaches in early cancer diagnosis and treatment are introduced with extensive experimental results. In particular, some novel materials have been synthesized with new properties that are most effective in cancer therapy. Some of the key issues are also addressed with these recent discoveries such as bio safety and bio degradability, that are essential in the success of nano medicine.An important aspect of this book set is the introduction of nanotechnology to the medical communities that are searching for new treatments of cancer. It may also break the barriers between the physical and medical sciences so that more MDs will be able to appreciate the new discoveries and establishments in medical diagnosis and therapy that will allow the effective handling of major clinical issues.This major reference publication will be important as the field of nanomedicine has been rapidly developing with a great deal of new information. It is anticipated that the research will soon advance into the pre-clinical stage. Therefore, this reference set can serve as valuable background information for future clinical studies.
