13 Σεπ 2024 · Nickel, chemical element, ferromagnetic metal of Group 10 (VIIIb) of the periodic table, markedly resistant to oxidation and corrosion. Silvery white, tough, and harder than iron, nickel is widely familiar because of its use in coinage but is more important as the pure metal or in the form of alloys.
24 Αυγ 2020 · We mentioned that recently available literature on nickel content in human body mostly concerns the material which can be easily obtained from living subjects, such as blood, urine or hair. The availability of post-mortem material, organs in particular, is still limited for a large group of researchers.
Nickel is a chemical element; it has symbol Ni and atomic number 28. It is a silvery-white lustrous metal with a slight golden tinge. Nickel is a hard and ductile transition metal.
Nickel is also an micronutritient essential for proper functioning of the human body, as it increases hormonal activity and is involved in lipid metabolism. This metal makes it's way to the human body through respiratory tract, digestive system and skin.
1 Σεπ 2020 · Nickel carbonyl, soluble nickel, is fat-soluble and can thus cross the cell membrane. Usually, it crosses through calcium channels and diffusion. Free calcium is released from the intracellular store due to nickel blocking the calcium channel and thus less calcium entering the intracellular space.
21 Ιαν 2020 · In nature, nickel is found in combination with antimony, arsenic, and sulfur; elemental nickel is a silver-white solid metal with high thermal and electrical conductivity. Nickel exists in +2 (Ni 2+) oxidation state; other valences (+3 and +4) may be found, even if they are less frequent.
