Chelation therapy uses high-affinity metal-binding molecules to form stable, excretable complexes with toxic metals, removing them from the body. The term derives from Greek "chele" (claw) -- the chelator grips the metal ion at multiple coordination sites. While chelati…
An essential trace element with a striking dual nature: required for survival as a cofactor for critical enzymes (SOD1, cytochrome c oxidase, ceruloplasmin), yet toxic in excess through Fenton-like redox cycling and mis metallation of iron-sulfur clusters. Copper is ele…
A synthesis of how dietary heavy metal exposure varies across the human lifespan, highlighting that the same metals present different risks at different developmental stages due to changing absorption rates, detoxification capacity, dietary patterns, and organ vulnerabi…
Firmicutes (recently reclassified as Bacillota) is the dominant bacterial phylum in the Western adult gut, comprising the core community of short-chain fatty acid (SCFA) producers that maintain intestinal barrier integrity, regulate immune function, and influence system…
Heavy metals is a widely used but chemically imprecise umbrella term for elements discussed because of their density, persistence, environmental occurrence, or toxicity. One common convention uses density above 5 g/cm3, but density alone does not determine biological ha…
Iron-sulfur (Fe-S) clusters are among the most ancient and ubiquitous metal cofactors in biology, present in all domains of life. These inorganic prosthetic groups -- typically [2Fe-2S] or [4Fe-4S] configurations -- mediate electron transfer, enzymatic catalysis, and re…
Chelation therapy uses molecules with high affinity for specific metal ions to form stable, excretable complexes, removing toxic metals from the body. The word derives from Greek "chele" (claw) -- the chelator grips the metal ion at multiple coordination sites. While ch…
Parenteral nutrition (PN) -- the delivery of nutrients directly into the bloodstream via intravenous infusion -- is a life-saving intervention for patients who cannot absorb nutrition enterally. However, PN presents unique challenges for the metal-microbiome axis: it in…
A non-essential metal with a 5,000-year history of antimicrobial use, silver has re-emerged as a critical tool in the post-antibiotic era. What makes silver particularly interesting from a metallomics perspective is not that it kills bacteria -- many metals do -- but ho…
Harm potential: RED — Following this STOP inappropriately could delay life-saving antibiotic therapy.
