Dimethylglyoxime (DMG) is a high-affinity, nickel-specific chelator — two DMG molecules coordinate one Ni²⁺ ion to form a characteristic red complex (Tschugaeff reaction). Unlike broad-spectrum chelation agents (EDTA, DMSA) that bind multiple divalent cations indiscrimi…

The ability of microorganisms to survive and replicate in the presence of antimicrobial agents — antibiotics, antifungals, antivirals, antiparasitic drugs — at concentrations that would normally inhibit or kill them. Antimicrobial resistance (AMR) is designated by the W…
A neurodevelopmental condition affecting approximately 1 in 36 children (US CDC 2023 estimate), characterized by differences in social communication, restricted interests, and repetitive behaviors. From a metallomics perspective, ASD presents a compelling convergence of…
Breast cancer is the most common cancer in women worldwide, with approximately 2.3 million new cases annually. While genetic, hormonal, and lifestyle factors are well-established risk determinants, the metallomic dimension reveals a consistent pattern of trace element d…
A heterodimer of S100A8 and S100A9 calcium-binding proteins that constitutes approximately 60% of the cytosolic protein content of neutrophils. Calprotectin is a central effector of nutritional immunity, sequestering essential transition metals from invading pathogens a…
A progressive loss of kidney function affecting approximately 850 million people worldwide (10–14% of adults), causing 1.2 million deaths annually. CKD is unique among diseases in this wiki because it occupies both sides of the metal-disease equation: heavy metals (Cd, …
The collective ability of the resident gut microbiome to prevent colonization by exogenous pathogens and suppress expansion of resident pathobionts. Colonization resistance is not a property of any single organism but an emergent function of the whole microbial communit…
Colorectal cancer (CRC) is the third most common cancer worldwide and the second leading cause of cancer death. Over 90% of cases are sporadic, driven by a complex interplay between genetic predisposition, dietary habits, gut microbiome composition, and environmental ex…
Coronary artery disease (CAD) -- the progressive narrowing of coronary arteries by atherosclerotic plaque -- is the single leading cause of death globally, responsible for approximately 9 million deaths annually. CAD encompasses stable angina, unstable angina, and myoca…
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…
This page identifies the contradictions and clinical dilemmas that become visible only when the 236 source pages in this wiki are read together. Each paradox describes a situation where evidence-based dietary or supplementation advice -- advice that is correct for most …
Affects approximately 48 million women worldwide (WHO global infertility prevalence estimates). From a microbiome-metallomics perspective, female infertility sits at the intersection of the estrobolome (microbial estrogen metabolism), heavy metal reproductive toxicity (…
Gastroesophageal reflux disease (GERD) is a chronic condition in which stomach acid or bile flows back into the esophagus, causing mucosal damage and symptoms such as heartburn and regurgitation. Affecting approximately 20% of Western populations, GERD is conventionally…
Alphabetical definitions of specialist terms used throughout this wiki. Where a full concept page exists, the term links to it. --- AhR (aryl hydrocarbon receptor) -- A ligand-activated transcription factor that senses microbial metabolites (especially indoles from tryp…
Graves' disease (GD) is an autoimmune thyroid disorder characterized by TSH receptor antibodies (TRAb) that stimulate the thyroid gland, causing hyperthyroidism kahaly 2022 graves disease targeted therapy review. It is the most common cause of hyperthyroidism, with conc…
Gut barrier dysfunction -- colloquially "leaky gut" -- is the pathological increase in intestinal permeability that permits translocation of bacteria, bacterial products (LPS, peptidoglycan), metals, and dietary antigens from the gut lumen into the systemic circulation.…
The gut-kidney axis describes the bidirectional relationship between the gut microbiome and kidney function. As kidney disease progresses, the resulting biochemical changes (uremia, altered pH, fluid shifts) reshape the gut microbiome. The dysbiotic microbiome, in turn,…
The gut-testis axis describes the bidirectional communication between the gut microbiome and the male reproductive system. Gut-derived microbial metabolites, immune signals, and systemic inflammatory mediators influence testicular function, testosterone biosynthesis, an…
Sustained elevation of systemic blood pressure, affecting an estimated 1.3 billion adults worldwide and the leading modifiable risk factor for cardiovascular disease, stroke, and chronic kidney disease. The gut microbiome-blood pressure axis has emerged as a major resea…
Indole-3-carbinol (I3C) and its metabolite 3,3'-diindolylmethane (DIM) — derived from cruciferous vegetables and also produced by gut bacteria from tryptophan metabolism — as multi-mechanism agents for ovarian cancer. Three independent papers support I3C through distinc…
A condition in which cells fail to respond normally to insulin, requiring progressively higher insulin levels to maintain glucose homeostasis. Insulin resistance is central to PCOS, type 2 diabetes, and metabolic syndrome, and has extensive but complex connections to me…
An anti-inflammatory dietary pattern characterized by high consumption of extra-virgin olive oil, fruits, vegetables, legumes, whole grains, nuts, and fish, with limited red meat, processed food, and added sugars. The Mediterranean diet (MD) has evidence across multiple…
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…
Transition metals serve as essential cofactors for pathogen virulence factors across virtually all domains of microbial life. The dependence of pathogens on metals they must scavenge from the host environment creates a fundamental tension at the heart of infectious dise…

An umbrella concept encompassing the metallomic dimensions of Alzheimer's disease, Parkinson's disease, and other neurodegenerative conditions. The brain is uniquely vulnerable to metal toxicity: it has high metabolic demand, limited regenerative capacity, region-specif…
Ovarian cancer is the most lethal gynecological malignancy, with approximately 314,000 new cases and 207,000 deaths annually worldwide. Its poor prognosis stems largely from late-stage diagnosis (70% at stage III/IV) and the development of chemoresistance. From a metall…
