  2. Metals in medicine - Wikipedia

    en.wikipedia.org/wiki/Metals_in_medicine

    Metals in medicine are used in organic systems for diagnostic and treatment purposes. [1] Inorganic elements are also essential for organic life as cofactors in enzymes called metalloproteins. When metals are under or over-abundant in the body, equilibrium must be returned to its natural state via interventional and natural methods.

  3. Metal toxicity - Wikipedia

    en.wikipedia.org/wiki/Metal_toxicity

    Metal toxicity or metal poisoning is the toxic effect of certain metals in certain forms and doses on life. Some metals are toxic when they form poisonous soluble compounds. Certain metals have no biological role, i.e. are not essential minerals, or are toxic when in a certain form. [ 1 ]

  4. Medical uses of silver - Wikipedia

    en.wikipedia.org/wiki/Medical_uses_of_silver

    Though toxicity of silver is low, the human body has no biological use for silver and when inhaled, ingested, injected, or applied topically, silver can accumulate irreversibly in the body, particularly in the skin, and chronic use combined with exposure to sunlight can result in a disfiguring condition known as argyria in which the skin ...

  5. Biometal (biology) - Wikipedia

    en.wikipedia.org/wiki/Biometal_(biology)

    Sodium is a metal where humans have discovered a great deal of its total roles in the body as well as being one of the only two alkali metals that play a major role in the bodily functions. It plays an important role in maintenance of the cell membrane potential and the electrochemical gradient in the body via the sodium-potassium pump and ...

  6. Copper in biology - Wikipedia

    en.wikipedia.org/wiki/Copper_in_biology

    The research to date has been valuable: genes can be turned off gradually to explore varying degrees of deficiency. [citation needed] Researchers have also demonstrated in test tubes that damaged DNA in the cells of a Menkes patient can be repaired. In time, the procedures needed to repair damaged genes in the human body may be found. [citation ...

  7. Composition of the human body - Wikipedia

    en.wikipedia.org/wiki/Composition_of_the_human_body

    Parts-per-million cube of relative abundance by mass of elements in an average adult human body down to 1 ppm. About 99% of the mass of the human body is made up of six elements: oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus. Only about 0.85% is composed of another five elements: potassium, sulfur, sodium, chlorine, and magnesium ...

  8. Toxic heavy metal - Wikipedia

    en.wikipedia.org/wiki/Toxic_heavy_metal

    A toxic heavy metal is a common but misleading term for a metal-like element noted for its potential toxicity. [4] Not all heavy metals are toxic and some toxic metals are not heavy. [ 5 ] Elements often discussed as toxic include cadmium , mercury and lead , [ 6 ] all of which appear in the World Health Organization 's list of 10 chemicals of ...

  9. Iron oxide nanoparticle - Wikipedia

    en.wikipedia.org/wiki/Iron_oxide_nanoparticle

    Iron oxide is easily degradable and therefore useful for in vivo applications [citation needed]. Results from exposure of a human mesothelium cell line and a murine fibroblast cell line to seven industrially important nanoparticles showed a nanoparticle specific cytotoxic mechanism for uncoated iron oxide.
