By Hossein Ameri, James D. Weiland, Mark S. Humayun (auth.), Mark S. Humayun, James D. Weiland, Gerald Chader, Elias Greenbaum (eds.)

Artificial sight is a frontier sector of contemporary ophthalmology combining the multidisciplinary talents of surgical ophthalmology, biomedical engineering, organic physics, and psychophysical trying out. Many clinical, engineering, and surgical demanding situations has to be surmounted prior to common sensible purposes will be learned. The objective of Artificial Sight is to summarize the state of the art examine during this fascinating quarter, and to explain a few of the present ways and projects which may support sufferers in a scientific atmosphere.

The Editors are energetic researchers within the fields of synthetic sight, biomedical engineering and organic physics. they've got acquired a variety of specialist awards and popularity for his or her paintings. the bogus sight staff on the Doheny Eye Institute, led by means of Dr. Mark Humayun, is a global chief during this zone of biomedical engineering and scientific research.

Key Features

  • Introduces and assesses the cutting-edge for a large viewers of biomedical engineers, biophysicists, and scientific researchers
  • Describes advances in microelectronics, microfabrication, surgical implantation, and psychophysical checking out of visible prostheses
  • Outlines the promise of man-made sight and the demanding situations that has to be met

Multiple Drug Resistance in Cancer: Cellular, Molecular and Clinical Approaches

This ebook is an up to date evaluation of present wisdom within the box of a number of drug resistance in human melanoma. The literature as much as the center of 1993 is surveyed in expert chapters written through diverse specialists. subject matters coated comprise the molecular genetics, cytogenetics and biochemistry of the mdr genes and P-glycoprotein; replacement shipping proteins in MDR; topoisomerases I and II; cytochrome p450-enzymes and glutathione- S-transferases in MDR; mobile types for MDR in sturdy tumours and haemopoietic tumours; immunochemical and molecular organic innovations for detection of MDR-related gene expression; and scientific and pharmacological concepts to bypass resistance.

Clinical Transplantation: Current Practice and Future Prospects

This quantity has been written in particular for the training clinician. All elements of medical transplantation have accelerated drastically in recent times, yet some of the medical professionals concerned have obtained very little school in immunology as scientific scholars. many of the chapters, written by way of physicians, surgeons, pathologists and immunologists current some of the at the moment very important concerns in transplantation and show uncomplicated venture of immunology is now crucial in lots of components of medical perform.

Alzheimer’s Dementia: Dilemmas in Clinical Research

The nationwide Institute on getting older (NIA) has traditionally been eager about the security of human matters. In July 1977, the NIA backed a gathering to replace and complement consultant­ strains for shielding these partaking in Federal study professional­ jects. even if the fundamental directions have been in impact given that 1966, it have been ignored to incorporate the aged as a weak inhabitants.

Bone Metastases: A translational and Clinical Approach

The second one version of this ebook serves either as an introductory and reference booklet targeting the sector of metastatic bone ailment. that includes contributions from specialists within the box, this quantity describes the molecular and mobile mechanisms serious about the formation of bone metastases, offers the more recent advances made within the figuring out of the medical photo and signs of sufferers, analyses the position of bone markers in study and scientific perform and bargains with all facets of imaging modalities utilized for the detection and review of bone metastases.

Subretinal prostheses are placed between the pigment epithelial layer and the outer layer of the retina. Although improvements in surgical and electronic technologies may solve some of the problems of implanting retinal stimulating prostheses, there is the potential risk of significant damage to the eye after inserting an electrode intraocularly. To avoid the risks of implanting a stimulating prosthesis into the epiretinal or subretinal space, we have developed a new approach for electrode implantation, namely STS, which avoids direct contact of electrodes with the retina [14].

2b, respectively). We first addressed the following issues: Can a focal STS to the retina with degenerated photoreceptors excite the residual neurons, especially RGCs, and can their excitation be transmitted via the optic nerve (ON) to the visual areas of the brain? 2.
