Metals and Metal Derivatives in Medicine
Mini-Reviews in Medicinal Chemistry, 2013Several chemical elements are required by living organisms in addition to the four elements carbon, hydrogen, nitrogen and oxygen usually present in common organic molecules. Many metals (e.g. sodium, potassium, magnesium, calcium, iron, zinc, copper, manganese, chromium, molybdenum and selenium) are known to be required for normal biological functions

Cytotoxicity of metals, metal-metal and metal-chelator combinations assayed in vitro
Toxicology, 1986A simple, rapid assay, based on the lysosomal incorporation of neutral red by cells, conveniently carried out in 96-well microtiter plates, was used to evaluate the cytotoxic effect of cationic and anionic metal salts on BALB/c mouse 3T3 fibroblasts.

Metal–Insulator–Metal Transistors
Advanced Materials, 2008A metal–insulator–metal field‐effect transistor has been fabricated. The device performance was achieved by reducing the density of states by only partially covering the substrate, which increases the relative field effect. An infinite on–off ratio, no lower limit to device dimensions, a generally enhanced flexibility in design, and low production ...

Commentary: Metal on metal hips
BMJ, 2011Total hip replacement is one of the most successful operations of the 20th century and is currently performed in 70 000 patients a year in the UK,1 250 000 a year in the United States, and one million worldwide. In an attempt to improve wear resistance and to allow bone conservation through hip resurfacing, metal on metal bearings were re-introduced in

Metal-on-metal Bearing Surfaces
Journal of the American Academy of Orthopaedic Surgeons, 2009Metal-on-metal bearing couples remain a popular option in total hip arthroplasty and are the only currently available option for surface replacement arthroplasty. In general, the intermediate-term clinical performance of metal-on-metal bearings has been favorable.
