  • The medical devices industry is booming. Growth in the industry has not stopped despite globally fluctuating economies. The main reason for this success is probably the self-sustaining nature of health care. In essence, the same technology that makes it possible for people to live longer engenders the need for more health-care technologies to enhance the quality of an extended lifetime. It comes as no surprise, then, that the demand for trained medical-device designers has increased tremendously over the past few years.

  • This book is a collection of some of the invited talks presented at the international meeting held at the Max Planck Institut fiir Physik komplexer Systeme, Dresden, Germany during August 6-30, 2001, on the rapidly developing field of nanoscale science and bio-electronics (http://www.mpipks-dresden.mpg.de/~nanobio/). Semiconductor physics has experienced unprecedented developments over the second half of the twentieth century. The exponential growth in microelectronic processing power and the size of dynamic memories has been achieved by significant downscahng of the minimum feature size.

  • This book is intended as an introductory text for Engineering and Applied Science Students to the Medical Applications of Electronics. A course has been offered for many years in Cardiff in this arena both in this College and its predecessor institution. A new group, the Medical Systems Engineering Research Unit, was established following the reorganisation of the College. Restructuring and review of our course material and placing the responsibility for teaching this course within the new group led to a search for new material.

  • Over a century ago, with the work of Alexander Graham Bell, the motivation underlying the first use of the telephone in communication had a health-related origin: a doctor attempted to be in contact with his deaf mother and sister. Early developments in electronic patient records took place over 40 years ago through the pioneering work of Ed Hammond and his interest in community and family medicine. Very soon, the European Union will be celebrating a 20-year history of co-financing eHealth research and development initiatives.

  • This series is directed to Healthcare professionals who are leading the transformation of health care by using information and knowledge. Historically, the series was launched in 1988 as Computers in Health Care, to offer a broad range of titles: some addressed to specific professions such as nursing, medicine, and health administration; others to special areas of practice such as trauma and radiology; still other books in the series focused on interdisciplinary issues, such as the computerbased patient record, electronic health records, and networked Healthcare systems.

  • In the summer of 1866, the author of this little book, moved by the repeated and earnest solicitation of his Medical Classes, prepared and printed a small pamphlet entitled Practical Principles of Medical Electricity, designed more particularly, as the present work also is, as a Hand-Book to assist the memory of those who have taken a regular course of LECTURES from himself, or from some other competent instructor in the same general system of Practice. The edition of that work was exhausted somewhat more than a year ago. Still, the book has continued to be frequently called for.

  • The functional replacement of the primary ubiquinone (QA) in the photosynthetic reaction center (RC) from Rhodo-bacter sphaeroideswith synthetic vitamin K derivatives has provided a powerful tool to investigate the electron transfer mechanism. To investigate the binding mode of these qui-nones to theQAbinding sitewe have determined the binding free energy and charge recombination rate from QA ± to D + (kAD) of 29 different 1,4-naphthoquinone derivatives with systematically altered structures.

  • This study on human cytochrome P450 reductase (CPR) presents a com-prehensive analysis of the thermodynamic and kinetic effects of pH and solvent on two- and four-electron reduction in this diflavin enzyme. pH-dependent redox potentiometry revealed that the thermodynamic equilibrium between various two-electron reduced enzyme species (FMNH • ,FADH • ; FMN,FADH2; FMNH2 ,FAD) is independent of pH.

  • The His332 residue of the D1 protein has been identified as the likely ligand of the catalytic Mn ions in the water oxi-dizing complex (Ferreira, K.N., Iverson, T.M., Maghlaoui, K., Barber, J. & Iwata, S. (2004) Science303, 1831–1838). However, its function has not been fully clarified. Here we used thermoluminescence and flash-induced chlorophyll fluorescence measurements to characterize the effect of theD1-H333E,D1-H332DandD1-H332Smutationson the electron transport of Photosystem II in intact cells of the cyanobacteriumSynechocystis6803....

  • To test thioredoxin resistance to oxidizing free radicals, we have studied the one-electron oxidation of wild-type thio-redoxin and of two forms with the point mutations D30A and W35A, using azide radicals generated byc-ray or pulse radiolysis. The oxidation patterns of wild-type thioredoxin and D30A are similar. In these forms, Trp35 is the primary target and is repaired by one-electron reduction; first by intramolecular electron transfer from tyrosine, and then fromother residues. Conversely, duringoxidationofW35A, Trp13 is poorly reactive.

  • NADPH-dependent dual-flavin enzymes provide electrons in many redox reactions, although the mechanism responsible for regulating their electron flux remains unclear. We recently proposed a four-state kinetic model that links the electron flux through a dual-flavin enzyme to its rates of interfla

  • Some 60 years after physicists helped to initiate the molecular-biology revolution that has produced so many medical miracles, biophysics is a growing dis- cipline worldwide. Yet in spite of the spectacular ad- vances in understanding the cell’s molecular machinery, something as widespread and pervasive as cancer re- mains a stubborn and growing medical problem. As the population ages, so the burden of cancer on society and on the economy is set to worsen.

  • In the apicoplast of apicomplexan parasites, plastidic-type ferredoxin and ferredoxin-NADP + reductase (FNR) form a short electron transport chain that provides reducing power for the synthesis of isoprenoid precursors. These proteins are attractive targets for the development of novel drugs against diseases such as malaria, toxoplasmosis, and coccidiosis.
