Microcytic anemia

Microcytic anemia: anemia with small red cells, MCV under 80 fL in adults. Main causes are iron deficiency anemia, thalassemia trait, anemia of inflammation, sideroblastic anemia, and lead toxicity; ferritin is the first diagnostic test.

MicroCyto (微元合成)

MicroCyto (微元合成) is a Beijing synthetic biology startup founded in 2021 by Liu Bo that applies AI to biomanufacturing, with commercialized products including allulose, lutein, and mannitol.

Microdata (HTML)

Microdata, one of three HTML5 structured-data syntaxes alongside RDFa and microformats, embeds machine-readable name–value pairs in web pages using attributes like itemscope and itemprop, most often with the schema.org vocabulary.

Microdermabrasion

Microdermabrasion is a cosmetic skin procedure that exfoliates the outermost skin layer with abrasive crystals or a diamond-tipped handpiece, treating photodamage, melasma, fine lines, and acne scars.

Microdialysis

Microdialysis is a sampling technique in which a semipermeable-membrane probe implanted in living tissue collects small soluble molecules from extracellular fluid for chemical analysis, mimicking a capillary.

Microdiscectomy

Microdiscectomy is a surgical procedure that removes herniated lumbar disc material pressing on spinal nerve roots, through a small incision with an operating microscope, to relieve leg pain.

Microdissection

Microdissection is a laboratory technique that uses a microscope to isolate specific cells or tissue regions from a section for DNA, RNA, or protein analysis.

Microdissection testicular sperm extraction

Microdissection testicular sperm extraction (micro-TESE) is a microsurgical procedure, introduced by P. N. Schlegel in 1999, that retrieves sperm for ICSI in men with non-obstructive azoospermia.

Microdontinae

Microdontinae is a mainly tropical subfamily of about 454 hoverfly species, commonly called ant flies, whose larvae live inside ant nests and prey on ant brood.

Microdosimetric kinetic model

The microdosimetric kinetic (MK) model is a radiobiological model predicting cell survival and RBE for ion beams, introduced by Roland Hawkins in 1996 and used in Japanese carbon-ion therapy planning.

Microdosimetry

Microdosimetry is the branch of radiation dosimetry that measures the random deposition of energy by ionizing radiation in microscopic, cell-sized volumes, developed by Harald H. Rossi from 1959 onward.

Microdosing

Microdosing: taking subperceptual intermittent doses of psychedelics (LSD, psilocybin) for mood or cognition, or phase 0 subpharmacologic drug testing (1/100 dose, 100 µg max) in humans.

microdrones (company)

Microdrones is a German manufacturer of surveying drones, founded in 2005 in Siegen and known for the md4 quadcopters and mdLiDAR and mdMapper product lines.

Microeconomics

Microeconomics, also known as price theory, is the branch of economics that studies individual agents such as consumers and firms and how markets set prices, in contrast with macroeconomics.

MicroED

MicroED, also known as 3D electron diffraction, is a crystallographic method that determines atomic-resolution structures from crystals far too small for X-ray diffraction, first demonstrated in 2013.

Microelectrode array

A microelectrode array (MEA), or multielectrode array, is a device with many microelectrodes on one substrate that record or stimulate neurons, in cell cultures or implanted in living tissue.

Microelectrode recording

Microelectrode recording (MER) is a neurosurgical technique that records single-neuron electrical activity to locate deep brain stimulation targets such as the subthalamic nucleus by their firing signatures.

Microelectrodes

Microelectrodes are micrometer-scale electrodes for recording or stimulating individual cells, chiefly glass micropipettes, metal, and solid-state types; developed from Barber's micropipettes through Graham and Gerard to modern high-density neural and cardiac arrays.

Microelectrophoresis

Microelectrophoresis is an electrokinetic technique that measures the electrophoretic mobility of microscopic particles suspended in a liquid, observed under a microscope while an electric field is applied.

Microemulsion

A microemulsion is a thermodynamically stable, optically transparent liquid mixture of oil, water, and surfactant that forms spontaneously, with dispersed domains of roughly 1 to 100 nm.

Microemulsion method

The microemulsion method is a synthesis technique in materials chemistry that uses microemulsion water droplets as nanoreactors to precipitate nanoparticles of controlled size, established in 1982.

Microemulsion polymerization

Microemulsion polymerization is a free-radical technique that polymerizes monomer inside thermodynamically stable microemulsion droplets, yielding latex particles of 10–50 nm, far smaller than conventional emulsion polymerization delivers.

Microencapsulated phase-change materials

Microencapsulated phase-change materials, abbreviated MPCM or MEPCM, are phase-change materials sealed inside tiny polymer or ceramic shells 1 μm to 1 mm wide, letting them store heat safely in buildings, textiles, and solar systems.

Microencapsulation

Microencapsulation is a technique that encloses a solid, liquid, or gaseous core within tiny wall-bound particles, used in pharmaceuticals, food, cosmetics, and carbonless copy paper.

Microendoscopy

Microendoscopy is a minimally invasive diagnostic technique that passes miniaturized optical probes into the body to image living tissue at the cellular level, enabling targeted biopsies.

Microextraction

Microextraction is a family of sample-preparation techniques in analytical chemistry that isolate and concentrate small amounts of analytes using minimal solvent or sorbent, typically before chromatographic analysis.

Microfactory

A microfactory is a small, modular, highly automated production facility that makes customized products in small quantities, a concept originating in Japan in the 1990s.

Microfiber

Microfiber is a synthetic textile fiber finer than 1 denier or dtex, typically 0.1 to 1.0 dtex, made as polyester-polyamide blends for cleaning cloths, sportswear, filtration, and insulation; the term also covers plastic microfibers shed during laundry, a major microplastic source.

Microfibril-associated glycoprotein

Microfibril-associated glycoproteins (MAGP-1/MFAP2, MAGP-2/MFAP5) are small cysteine-rich ECM proteins covalently attached to fibrillin microfibrils, binding active TGFβ and BMPs, and linked to aneurysm and metabolic disease.
