Welcome to the tag category page for Intestine!
The gut–brain axis refers to bidirectional biochemical and neural communication between the gastrointestinal tract and the central nervous system, with gut microbiota acting as a central mediator. Signaling occurs via the enteric nervous system and vagus nerve, immune and inflammatory pathways, enteroendocrine hormones, microbial metabolites and effects on intestinal barrier function. This network links digestion with mood, cognition, stress responses and metabolic regulation, and is implicated in functional gastrointestinal disorders, depression, neurodevelopmental and neurodegenerative conditions, and metabolic disease. Research is advancing rapidly, driving interest in interventions such as dietary modulation, prebiotics and probiotics (sometimes called psychobiotics), fecal microbiota transplantation and targeted microbial therapeutics, but many causal pathways and treatment effects remain unproven or preliminary. Commercial and clinical development faces challenges including variability in individual microbiomes, trial reproducibility, regulatory frameworks and safety. The trend spans pharmaceuticals, diagnostics, nutrition and digital health, and is prompting cross-sector investment in microbiome sequencing, bioinformatics and personalized approaches to brain–gut health.
Mayo scissors are a type of surgical scissors used for cutting thick tissues like those found in the uterus, muscles, breast, and foot. They can be straight or curved and are made of stainless steel. The main difference between straight Mayo scissors and Metzenbaum scissors is that Mayo scissors are heavier and designed for cutting tougher tissue, while Metzenbaum scissors are lighter and used for fine dissection. Mayo scissors were developed by surgeons at the Mayo Clinic and are named after the clinic. They are strong and designed to cut rigid structures, and can also be used for cutting sutures. They are not typically used for cutting bandages.
