2010; Chorny et al. 2010). This research is still quite new, however, and the question remains as to whether or not nanoparticles can truly serve as a replacement for stents by prohibiting plaque growth through a variety of means, including more targeted and longer-range delivery of pharmaceutical substances that destroy such build-ups and inhibit plaque deposits from forming. The efficacy of this approach has already been preliminarily demonstrated, but the long-term viability and safety of this intervention method as well as attendant risks have not yet been fully determined (Chan et al. 2010; Chorny et al. 2010).
IV. Motivation for Research
Despite the numerous advancements that have been made in treating plaque build-up in arteries and the general treatment and control of other cardiac issues, coronary artery disease is still the leading cause of death in North America and is a significant problem in other parts of the world, as well (Schoenhagen & Nissen 2003). This provides ample motivation for the study of techniques that might be more effective in treating and preventing coronary artery disease than those that are currently employed; the benefits of such research will directly impact the lives of many individuals by providing increasingly effective, less invasive, and more cost-effective treatments that prolong life and improve the quality of life. There are also more intrinsic motivations for conducting this research, including the ability to develop knowledge and work at the forefront of medical and engineering science, and though personal these motivations are not to be taken lightly.
V. Improvement...
Nanomachines The Science of molecular size machines and its engineering designs and constructions until late 1980s were not considered practicable. Nanotechnology, according to the leading exponents of that time were neither feasible nor viable, due to the fact of total structural difference of the constituent of nano-molecular device i.e. Atoms from the mechanical objects of every day life. The essential components of engineering mechanics i.e. cogwheels, gears or motors could not
(World Bank, 2007) Modern approaches to plant cloning or tissue culture techniques have been utilized by various nurseries in Thailand and the U.S. To bring rare and new species of plants in the commercial market, sometimes even before the botanists can manage to give the species a name. (Ogden, 2007) Tissue engineered products have a bright marketing potential since they provide better alternatives to other forms of treatments. Cartilage and
Miniature Antennas for Biomedical Applications Most of the studies on microwave antennas for medical applications have concentrated on generating hyperthermia for medical treatments and monitoring several physiological parameters. The types of antenna implanted depend of the location. Besides the medical therapy and diagnosis the telecommunications are considered as significant functions for implantable medical devices those needs to transmit diagnosis information. The design of the antennas catering to MEMS and NANO
