Elan Drc Icp-ms System with Dynamic Bandpass Tuning
Introduction Inductively Coupled Plasma Mass Spectrometry (ICP-MS) typically provides detection limits in the low-ppt to sub-ppt range for all but a few of over 70 elements. Unfortunately, for a handful of elements, conventional ICP-MS cannot provide the best possible detection limits. The detection limits for these elements are limited by plasma or sample matrix-based polyatomic interferences....
متن کاملSerum concentration of selected macro- and microelements and their correlation with the risk of breast and ovarian cancer among BRCA1 mutation carriers
The study was conducted to determine the correlations between serum concentration of selected macroand microelements, namely: magnesium (Mg), copper (Cu), zinc (Zn), arsenic (As), calcium (Ca), cadmium (Cd) chromium (Cr) and selenium (Se) with increased or decreased predisposition to breast and ovarian cancer. The subjects selected for the trial were Polish women, positive for at least one of t...
متن کاملThe Determination of Iodine in Food with the ELAN DRC-e ICP-MS
Introduction Iodine is essential for the production of thyroid hormones. These hormones stimulate metabolism in the body, as well as mental growth and development. The recommended daily iodine intake is 0.1-0.2 mg, with the most common sources of iodine being fish, seafood, milk and food supplements. The determination of iodine in food has always been difficult due to the low concentrations (mg...
متن کاملArsenic (As) and breast cancer risk
All subjects analyzed in the study were divided into two groups. The subjects from the first group were Polish women, positive for at least one of three founder mutations in BRCA1 gene dominating in Poland (5382insC, C61G, 4153delA). In the second group were Polish women, with breast cancers, unselected but negative for BRCA1 gene mutation. Persons with detected tumor were considered as cases a...
متن کاملSerum concentration of iron as predictor of cancer risk among BRCA1 mutation carriers
The aim of the study is identification of correlations between the serum concentrations of iron and the risk of breast and/or ovarian cancer among female BRCA1 mutations carriers. The subjects selected for the trial were Polish women, positive for at least one of three founder mutations in BRCA1 gene dominating in Poland (5382insC, C61G, 4153delA). Persons with detected tumor were considered as...
