  • Age-related hearing loss or presbycusis is mainly caused by changes in the inner ear. However, your genes and loud noises (such as from rock concerts or music headphones) may play a large role. Initially there is difficulty in hearing high-frequency sounds, such as someone talking. As hearing gets worse, it may become difficult to hear sounds at lower pitches. Hearing aids Telephone amplifiers and other assistive devices may be helpful. A cochlear implant (Surgery) may be recommended for certain women with very severe hearing loss.

  • Nanotechnology in Biology and Medicine is intended to serve as an authoritative reference for a wide audience involved in research, teaching, learning, and practice of nanotechnology in life sciences. Nanotechnology, which involves research on and the development of materials and species at length scales between 1 to 100 nm, has been revolutionizing many important scientific fields ranging from biology to medicine. This technology, which is at the scale of the building blocks of the cell, has the potential of developing devices smaller and more efficient than anything currently available.

  • For 30 years, the field of medical device technology has struggled to identify the specifications for optimal biocompatibility. For the vast majority of devices, clinical experience has eventually confirmed that the best performance is achieved when biocom-patibility is equated with biological safety that is materials are selected on the basis of maximizing bioinertness and minimizing toxicity and irritation.

  • The risks associated with all aspects of fracturing have been looked at from a variety of perspectives, but most concerns revolve around the use of water resources and their potential contamination [6]. Other risks are associated with surface spills [7,8]. The United States Environmental Protection Agency (EPA) has been investigating drinking water contamination and is expected to complete an extensive study on all aspects of hydraulic fracturing in 2014 [9].

  • Since their first introduction, metallic biomaterials have always been designed to be corrosion resistant. For decades, this paradigm has become the mainframe of the biomaterials world. It has been cited in thousands of scientific papers and taught in hundreds of courses of materials for biomedical devices. It has also been followed by industries in developing millions of medical devices until today. Nowadays, with the advent of tissue engineering, biomaterials are envisaged to actively interact with the body.
