Medical Device Design: Innovation from concept to market

This e-book presents the bridge among engineering layout and clinical equipment improvement. there isn't any unmarried textual content that addresses the plethora of layout concerns a clinical units dressmaker meets while constructing new items or bettering older ones. It addresses clinical units' regulatory (FDA and ecu) requirements--some of the main stringent engineering standards globally.

Biomaterials and Regenerative Medicine in Ophthalmology

With an more and more elderly inhabitants, eye illnesses have gotten extra frequent. Biomaterials have contributed lately to varied clinical units for the recovery of eyesight, enhancing many sufferers' caliber of lifestyles. therefore, biomaterials and regenerative medication have gotten more and more very important to the advances of ophthalmology and optometry.

Religion and the Implications of Radical Life Extension

What if you happen to discovered you'll stay a fit lifestyles lasting for 1000 years or longer? Advances in biomedical know-how increase the theoretical hazard that folks may well dramatically lengthen or perhaps indefinitely expand “healthy” human lifestyles. If this technology of “radical lifestyles extension” is discovered and the expertise turns into greatly to be had, it's going to arguably have a extra radical influence on humanity than the other improvement in background.

We developed magnetofection [169] after learning about the concept of magnetic drug targeting. 4. Principle of magnetofection in cell culture. Polyelectrolyte-coated magnetic nanoparticles are mixed with naked nucleic acids or synthetic or viral nucleic acid vectors in salt-containing buffer. The particles associate with nucleic acids and vectors by electrostatic interaction and/or salt-induced colloid aggregation. The mixtures are added to cells in culture. The cell culture plate is positioned on a magnetic plate during 5–30 min of incubation.

Since the concepts of gene therapy were first formulated almost 40 years ago, this field has experienced scientific breakthroughs, enthusiastic expectations, and serious setbacks. The validity and feasibility of the concepts have been demonstrated in thousands of animal experiments and in human clinical studies. Given the tremendous potential of nucleic acid-based therapies, the obvious question is why such therapies have not developed into widely practiced, state-of-the-art treatments, at least in specialized hospitals, all over the world.

The magnetic plate consists of 96 individual neodymium–iron–boron magnets (IBS Magnets, Berlin, Germany) inserted in drill holes in an acrylic glass or PVC plate in strictly alternating polarization. The plate was designed for application with 96-well cell culture plates but is also applicable for 24-, 12- and 6-well layouts, petri dishes of various diameters, and culture flasks of various sizes. com. Reproduced from Ref. 209. applicable in vivo for increasing the concentration of a drug formulation at the target cell surface.
