24 Αυγ 2020 · Although data on the concentration of nickel in blood [13–18], urine [13–16, 19–22] or hair [14–16] can be found among recently published literature, only a few publications regarding nickel content in human internal organs are available.
18 Φεβ 2020 · In the cell, nickel has to be correctly delivered and incorporated into the desired enzyme active sites. These processes often require an intricate team of accessory proteins, working in concert for the biosynthesis of these complex metalloclusters enzymes.
15 Απρ 2021 · In summary, nickel affects thyroid hormones in the hypothalamus–pituitary–thyroid axis, material and energy metabolism, and the oxidative breakdown of energy sources in the body, namely proteins, carbohydrates and fats.
24 Αυγ 2020 · That is why it is of a great importance to establish “reference” levels of particular elements (essential or toxic) in human biological samples. The aim of this paper was to determine nickel in autopsy tissues of non-occupationally exposed subjects in Southern Poland (n = 60).
All values of nickel concentrations found in internal organs according to gender and age are presented in Tables 1 and 2, respectively. The tables summarize the mean, median and ranges of nickel concentration values of the analysedsamples together with standard deviation values which can reflect the individual differences between subjects.
In this chapter, the current knowledge on the role of nickel ions in biological systems is summarized, with a special emphasis on the eight nickel-enzymes known so far as well as the accessory proteins involved in the nickel delivery steps required for nickel-enzyme maturation.
5 Δεκ 2013 · Found in a wide variety of bacteria and archaea, NikR is a transcription factor that regulates intracellular nickel homeostasis. The activities of NikR homologs from several microorganisms have been examined in detail both in vitro and in vivo.
