The Microbiome Theory posits that gut balance promotes health, while imbalances (dysbiosis) cause disease, suggesting restoration as treatment.

Müllerianosis theory posits that embryonic Müllerian duct remnants misplace and differentiate, forming endometrial-like tissues in non-uterine locations post-puberty, contributing to conditions like endometriosis.

Lymphovascular Metastasis Theory posits that endometrial cells spread via blood and lymph systems, causing distant endometriosis. Evidence is promising but limited.

Coelomic Metaplasia Theory could help explain the cases of endometriosis in men or in women who are not yet menstruating.

The environmental theory of endometriosis suggests exposure to toxins like dioxins and CBs may contribute to its development by disrupting hormones, modulating the immune system, and promoting inflammation.

Retrograde menstruation theory holds that during menstruation, some endometrial tissue reverses through the fallopian tubes into the pelvic cavity. It implants on pelvic organs, thickens, breaks down, and bleeds cyclically, causing inflammation, pain, and scar tissue, characteristic of endometriosis.

An endometrioma is a type of ovarian cyst filled with old blood, arising from endometrial tissue outside the uterus, typically causing pain and potentially impacting fertility.

Transition metals like iron, zinc, copper, and manganese are crucial for the enzymatic machinery of organisms, but their imbalance can foster pathogenic environments within the gastrointestinal tract.

The Chronic Inflammation Hypothesis suggests that persistent inflammation contributes to the development and progression of various chronic diseases, including cancer, diabetes, and cardiovascular disorders.

Bacteria regulate transition metal levels through complex mechanisms to ensure survival and adaptability, influencing both their physiology and the development of antimicrobial strategies.

Definition Molecular mimicry is a biological phenomenon where the molecules (usually proteins or peptides) of one organism mimic the molecular structures of another organism. This mimicry can occur between molecules of different viruses, between viruses and the host, or between different cellular components within an organism.Fundamental Molecules: At the most basic level, molecular mimicry involves […]

Virulence factors are molecules produced by pathogens that contribute to their ability to infect, colonize, and cause disease in host organisms by evading the immune system or damaging host tissues.

Dimethylglyoxime (MG) is a chemical compound known for its ability to selectively chelate Nickel ions (Ni^2+), forming a bright red precipitate. This property has made MG a useful reagent in analytical chemistry for detecting and quantifying nickel. In fighting pathogens with nickel-dependent enzymes, such as those possessing urease or hydrogenase essential for their survival and […]

Drug repurposing involves identifying new therapeutic uses for existing drugs, offering a cost-effective and time-efficient pathway to enhance treatment options and address unmet medical needs.

A low-nickel diet (NiD) is a therapeutic dietary intervention that eliminates high-nickel foods, primarily plant-based sources such as legumes, nuts, whole grains, and cocoa, to reduce systemic nickel exposure. It is clinically validated for managing systemic nickel allergy syndrome (NAS) and nickel-induced eczema. Its relevance is well-established in microbiome modulation, with studies demonstrating clinical benefits in conditions such as endometriosis, fibromyalgia, irritable bowel syndrome, and ERD.

Microbiome signatures are reproducible ecological and functional patterns—encompassing traits, interactions, and metabolic functions—that reflect microbial adaptation to specific host or environmental states. Beyond taxonomy, they capture conserved features like metal metabolism or immune modulation, enabling systems-level diagnosis and intervention in health and disease.

Your microbiome is the collection of microorganisms (such as bacteria, fungi, and viruses) that live on and in your body. It is unique to you and can be influenced by various factors, including your diet, environment, and genetics. Determining your own unique Microbiome Signature can be performed by undergoing microbiome testing. This can be done […]

Photobiomodulation (BM), formerly known as Level Laser Therapy (LLT), is a non-invasive therapeutic technique involving the application of light, typically in the red to near-infrared (IR) spectrum, to promote tissue repair, reduce inflammation and pain, and provide various other therapeutic effects. This technique has gained significant attention in clinical and research settings due to its […]
