Mucormycosis

Mucormycosis, also known as black fungus, is a rare fungal infection caused by Mucorales molds, killing roughly half of those affected and requiring amphotericin B and surgery.

Mucoromycotina, a subphylum of Mucoromycota fungi (formerly zygomycetes), includes Mucorales, Endogonales, and Umbelopsidales; chitosan cell walls, columella, saprotrophs, liverwort symbionts, and mucormycosis agents.

Mucorpepsin (Rhizomucor miehei aspartic protease)

Mucorpepsin (EC 3.4.23.23), also called Miehei coagulant, is the aspartic protease from Rhizomucor miehei and R. pusillus used as the major microbial rennet substitute, cleaving κ-casein at Phe105-Met106 for cheesemaking.

Mucosal ablation

Mucosal ablation is an endoscopic procedure that destroys abnormal mucosal tissue, most commonly precancerous Barrett's esophagus epithelium, using thermal methods like radiofrequency ablation and argon plasma coagulation, or nonthermal cryoablation.

Mucosal administration

Mucosal administration is a drug delivery route giving medication across mucosal membranes, including nasal, buccal, sublingual, rectal, vaginal, and ocular surfaces, allowing rapid uptake and avoiding first-pass metabolism.

Mucosal cyst of postmastoidectomy cavity

Mucosal cyst of postmastoidectomy cavity (ICD-11 AB91, ICD-10 H95.13, formerly ICD-9 383.31): a mucosa-lined cyst forming in the mastoid after mastoidectomy, presenting with discharge and hearing loss, treated by complete cyst wall removal.

Mucosal Immunity

Mucosal immunity: immune defense at the gastrointestinal, respiratory, and urogenital mucous membranes, mediated mainly by secretory IgA, distinct from systemic immunity and central to mucosal vaccine development.

Mucosal melanosis

Mucosal melanosis (ICD-11 ED61.1) is benign flat pigmentation of oral, genital, or conjunctival mucosa with normal melanocyte counts; it mimics mucosal melanoma, and conjunctival primary acquired melanosis can progress to melanoma.

Mucosectomy

Mucosectomy is an endoscopic procedure, known in the digestive tract as endoscopic mucosal resection (EMR), that removes a disk of mucosa to treat early cancers and precancerous lesions without surgery.

Mucous membrane

A mucous membrane, or mucosa, is the moist epithelial lining of body cavities such as the gut, respiratory passages, and mouth, which produces mucus and aids immunity.

Mucous membrane pemphigoid

Mucous membrane pemphigoid, also called cicatricial pemphigoid, is a chronic autoimmune subepithelial blistering disease of mucous membranes, mainly oral (85%) and ocular (65%), targeting BP180, BP230, laminin 332, and type VII collagen.

Mucous neck cell of gastric gland

Mucous neck cell (MUC6, Gkn3, Tff2-expressing) of the gastric corpus gland neck; long-lived secretory cell that migrates basally and transdifferentiates without division into pepsinogen-secreting chief cells.

Mucuna

Mucuna is a pantropical genus of about 112 accepted liana species in Fabaceae, tribe Phaseoleae, first published in 1763. Known for irritant pod hairs, explosive mammal pollination, floating seeds, and the velvet bean Mucuna pruriens.

Mucuna pruriens

Mucuna pruriens (velvet bean, cowitch, kapikacchu), a tropical Fabaceae climbing legume with irritant pod hairs, whose seeds contain 4–6% levodopa and have been trialed as a Parkinson's disease treatment and nitrogen-fixing cover crop.

Mucus

Mucus: viscoelastic secretion of goblet and mucous cells lining organs exposed to the external world; 90-98% water plus mucin glycoproteins; forms protective, lubricating barriers in airways and gut.

Mud (2012 film)

Mud (2012 film), also called Mud, is Jeff Nichols's American Southern coming-of-age adventure drama starring Matthew McConaughey, Tye Sheridan, and Reese Witherspoon; it premiered in Cannes competition in 2012, earned a 97% Rotten Tomatoes score, and won the 2014 Independent Spirit Robert Altman Award.

Mud dauber

A mud dauber, also called a dirt dauber or dirt dobber, is a solitary wasp that builds mud nests and stocks them with paralyzed spiders for its young.

Mud flat

A mud flat is a level coastal or lakeshore area of fine-grained sediment that the tide alternately covers and uncovers, forming in sheltered bays, estuaries, and lagoons.

Mud logging

Mud logging is a wellsite monitoring method in petroleum geology that analyzes drilling mud and rock cuttings to detect hydrocarbons while a well is drilled, standard on rigs since the 1930s.

Mud motor

A mud motor, also called a drilling motor or positive displacement motor (PDM), converts circulating drilling fluid into rotation of the drill bit, enabling modern directional drilling.
