Intracellular metal transport proteins
Metal ions are essential cofactors for functional expressions of many proteins in living organisms. In cells, several trace elements are needed to activate and stabilize enzymes, such as superoxide dismutase, metalloproteases, protein kinases, and transcriptional factors containing zinc finger proteins. Recently, intracellular metal trafficking proteins, that carry metal ions to specific target...
متن کاملForeign body detected by patients using metal detectors.
A positive response from a metal detector when run over an area of the body is a strong positive indicator of the presence of a metallic object. If there is a possibility of a buried metallic foreign body this positive finding should not be ignored.
متن کاملAnalysis and Test of Overhanging-Metal Microstrip Detectors
The adoption of overhanging-metal contacts have been suggested as an effective mean to limit breakdown risks in heavy-damaged, high-voltage biased microstrip detectors. In this summary, the influence of such overhangs on device noise parameters is analyzed, with particular reference to the interstrip capacitance. Data have been collected on a set of detectors featuring variable overhang extensi...
متن کاملElectromagnetic Compatibility Testing of Implantable Neurostimulators Exposed to Metal Detectors
This paper presents results of electromagnetic compatibility (EMC) testing of three implantable neurostimulators exposed to the magnetic fields emitted from several walk-through and hand-held metal detectors. The motivation behind this testing comes from numerous adverse event reports involving active implantable medical devices (AIMDs) and security systems that have been received by the Food a...
متن کاملDetection of orthopaedic implants by airport metal detectors.
INTRODUCTION We performed a questionnaire study to establish the frequency and consequences of the detection of orthopaedic implants by airport security and to help us advise patients correctly. All published literature on this subject is based on experimental studies and no 'real-life' data are available. PATIENTS AND METHODS A total of 200 patients with a variety of implants were identified...
