Despite these limitations, there was no sampling bias for selection of days for measuring metal levels and corresponding health utilization, because days for measurement were not chosen based on levels of ED visits or anticipated levels of metals (Rubin 1976).
Among the available techniques, those with low detection limits (e.g., graphite furnace atomic absorption spectrometry, inductively coupled plasma mass spectrometry) might be especially suitable for measuring metal levels in the general population in low-exposure environments.
Here, hepatic copper deficiency in ob/ob mice was unmasked by measuring metal levels in defatted-dried tissue (Table 2): this obviated the interference that was caused by the excluded-volume effect of elevated hepatocellular lipids (HCL) when metal levels were measured in unmodified hepatic tissue (Table 1).
For studies measuring metal ion levels, an important consideration is the valency (electron charge) of these ions.
While the present study did not measure metal ion levels, the results did not indicate an association with implant failure and acetabular inclination.
We measured cortical metal levels by ICP-MS in three biochemical fractions and correlated these with mutant huntingtin protein levels in the same fractions.
The purpose of the study was to measure metal ion concentration (Ti, Co, Cr, Mo, Ni, Al) around loosened femoral stems and compare their levels around uncemented and cemented implants.
The aim of the study was to measure metal ion concentration (titanium - Ti, cobalt - Co, chrome - Cr, molybdenum - Mo, nickel - Ni, aluminium - Al) around loosened femoral stems and compare their levels around uncemented and cemented implants.
