Endometriosis involves ectopic endometrial tissue causing pain and infertility. Validated and Promising Interventions include Hyperbaric Oxygen Therapy (HBOT), Low Nickel Diet, and Metronidazole therapy.

In a rat model, metformin suppressed endometriotic implant growth and lowered VEGF and MMP-9 while raising the receptivity markers LIF and HOXA10, optimal at 100 mg/kg per day.

The microbiome and metallomic signature of tuberculosis: how iron withholding, copper/zinc intoxication, granuloma oxygen ecology, and airway–gut dysbiosis shape susceptibility, progression, and treatment — with triangle-tested interventions and STOPs.

Mycobacterium tuberculosis (Mtb) is the obligate-aerobic, acid-fast bacillus that causes tuberculosis — an intracellular macrophage pathogen and iron pirate that survives phagosomal copper/zinc intoxication and granuloma hypoxia.

A four-group sputum microbiome study in India found that tuberculosis and COVID-19 co-infection reshaped airway bacterial composition and upregulated surfactant-lipid metabolic pathways relative to TB alone, with shifts that tracked toward adverse TB outcomes.

A 16S rRNA study of rifampicin-resistant tuberculosis found depleted sputum microbiota diversity and a distinct pathobiont-shifted community that persisted unchanged through six months of intensive-phase second-line therapy.

A cross-sectional study of 90 Chinese adults linked progressive gut microbiome depletion to falling CD4/CD8 ratios and shifted cytokines across tuberculosis stages, yielding a 20-genus classifier that distinguished patients from healthy controls.

A Chinese fecal 16S rDNA study found that the gut microbiota becomes progressively less diverse and more pro-inflammatory along the latent-to-active tuberculosis spectrum, with depletion of beneficial taxa such as Romboutsia and enrichment of organisms like Ruminococcus gnavus and Streptococcus.

In poorly controlled diabetes, a six-genus gut microbiota signature distinguished latent tuberculosis infection and tracked with Th1/Th17 cytokine responses, predicting LTBI status with 87% accuracy.

This rigorously designed study compared heavy metal excretion in sweat from treadmill running (5-10 km/h, 25°C) versus sauna exposure (45°C). Exercise produced significantly higher concentrations of nickel, lead, copper, and arsenic, indicating dynamic activity may enhance detoxification more effectively than passive heating.

This review highlights Amuc_1100, a bioactive membrane protein from Akkermansia muciniphila, as a potent immunometabolic regulator that strengthens gut barrier function, reshapes microbiome composition, and modulates systemic inflammation across metabolic, inflammatory, and oncologic disease models.

This study explores the critical role of iron transport and metabolism in Listeria monocytogenes, focusing on key systems for iron acquisition and their implications for bacterial virulence and pathogenesis.

This study demonstrates that gentamicin combination therapy significantly reduces 90-day mortality in patients with invasive listeriosis, especially in those with neurolisteriosis.

This study shows that manganese bio-oxidation, facilitated by Pseudomonas aeruginosa strain MQ2, can effectively degrade antibiotics and reduce antibiotic resistance gene propagation by alleviating oxidative stress, offering new strategies for environmental antibiotic pollution control.

This study explores the impact of metal exposure on infant gut microbiota, identifying key metals like arsenic, copper, and manganese that alter microbial diversity and specific taxa, with implications for infant health and future therapeutic strategies.

This study uncovers the structural basis of manganese binding in the MntR regulator from Bacillus halodurans, revealing its role in bacterial manganese homeostasis. Understanding this process could inform new strategies for controlling bacterial infections by targeting metal regulation.

Overview Alzheimer’s disease (AD) is a progressive neurodegenerative disorder characterized by amyloid-beta (Aβ) plaques, neurofibrillary tangles, neuroinflammation, and metabolic dysfunction, ultimately leading to cognitive decline and dementia. Emerging research highlights the microbiota-gut-brain axis as a crucial factor in AD pathogenesis, with gut dysbiosis contributing to neuroinflammation, immune dysregulation, and blood-brain barrier permeability. Microbial metabolites, such […]

Autism Spectrum Disorder (ASD) is a neurodevelopmental condition characterized by social, communication, and behavioral challenges. It involves genetic and environmental factors, including microbiome imbalances which influence symptom severity and overall health.

Traditionally linked to genetic predispositions and environmental exposures, emerging evidence highlights the microbiome as a critical and underappreciated factor influencing breast cancer progression, immune response, and treatment outcomes.

OverviewGraves’ Disease (GD) affects approximately 0.5% of the population, predominantly women. First-line treatment options—antithyroid medications, radioactive iodine, and surgery— often result in significant side effects, incomplete remissions, and frequent relapses. Further, current first-line treatment options focus on symptoms management, and reflect an inadequate understanding of the etiology of the condition. However, recent research reveals a […]

Hashimoto’s Thyroiditis (HT) is an autoimmune disease that progressively damages the thyroid, often causing hypothyroidism and affecting women disproportionately. Research links HT to gut dysbiosis via the gut–thyroid axis and highlights heavy metals like nickel, arsenic, and lead as contributors to oxidative stress and thyroid dysfunction.

Irritable Bowel Syndrome (IBS) is a common gastrointestinal disorder characterized by symptoms such as abdominal pain, bloating, and altered bowel habits. Recent research has focused on the gut microbiota’s role in IBS, aiming to identify specific microbial signatures associated with the condition.

Parkinson’s disease is increasingly recognized as a systemic disorder involving coordinated disturbances across the gut–brain axis, rather than a condition confined to dopaminergic neurodegeneration alone. Converging evidence implicates gut dysbiosis, altered microbial metabolites, impaired intestinal barrier integrity, and metal dyshomeostasis as upstream drivers of neuroinflammation and alpha-synuclein pathology. These interconnected microbiome, metabolomic, and metallomic signals provide a mechanistic framework for understanding disease initiation, progression, and therapeutic targeting beyond the central nervous system.

OverviewRheumatoid arthritis (RA) is a systemic autoimmune disease marked by chronic joint inflammation, synovitis, and bone erosion, driven by Treg/Th17 imbalance, excessive IL-17, TNF-α, and IL-1 production, and macrophage activation. Emerging evidence links microbial dysbiosis and heavy metal exposure to RA, [1][2] with gut microbiota influencing autoimmune activation via Toll-like receptor (TLR) signaling, inflammasome activation, […]
