Ependyma
Ependyma: ciliated simple cuboidal epithelium (ependymocytes, tanycytes, choroid plexus) lining brain ventricles and spinal central canal; radial-glia derived glia driving CSF flow at 28–40.7 Hz, partial CSF–brain barrier, ependymoma origin.
Ependymin
Ependymin (epd, EPDR family) is a calcium-binding secreted glycoprotein abundant in teleost fish cerebrospinal fluid, first found in goldfish in 1976, implicated in memory consolidation, axon growth, and regeneration, with related proteins (MERPs, UCC1) across eukaryotes.
Ependymoma
Ependymoma, also known as ependymal tumor, is a glioma arising from ependymal cells lining the brain's ventricles and spinal canal, treated with surgery and radiation.
Eperisone
Eperisone (エペリゾン) is a centrally acting muscle relaxant and analgesic launched in Japan in 1983 by Eisai, used for muscle tone disorders and spastic paralysis; in 2024 it was identified as a potent P2X7 receptor antagonist.

EPF study (NCT03235310)
EPF study, NCT03235310, is the registration of the French Perinatal Cohort (ANRS CO1/CO11), a prospective observational cohort since 1986 of HIV-infected pregnant women in 90 French centers, tracking mother-to-child HIV transmission, PMTCT safety, and birth defects including the zidovudine heart-defect association.
EPF study (NCT03306251)
EPF study, NCT03306251, ANRS CO11: French national observational cohort of children born to HIV-positive mothers, run with ANRS CO1 since 2005 to monitor mother-to-child HIV transmission and perinatal antiretroviral toxicity.
EPHA2
EPHA2 (EPH receptor A2, formerly Eck) is a human chromosome 1p36 gene encoding a 976-amino-acid ephrin-A-binding receptor tyrosine kinase; kinase and SAM domain mutations cause inherited cataract, and ligand-independent S897 signaling drives cancer progression.
EPHB2
EPHB2 (EPH receptor B2, also Hek5/ERK/Nuk) encodes a human Eph-family receptor tyrosine kinase at 1p36.12 that signals bidirectionally with ephrin-B ligands in axon guidance, synaptic plasticity, intestine, platelets, and cancer; mutations cause BDPLT22.
EPHB4
EPHB4 (also HTK, Tyro11) is a gene at 7q22.1 encoding the EphB4 receptor tyrosine kinase, which binds ephrin-B2 and is essential for vascular development; mutations cause CM-AVM2 and predispose to vein of Galen malformation.
EPHB4-related capillary malformation-arteriovenous malformation
CM-AVM2 (OMIM 618196), also called EPHB4-related capillary malformation-arteriovenous malformation, is a rare autosomal dominant vascular disorder from EPHB4 loss-of-function variants, mimicking CM-AVM1 and HHT.
Ephebophilia
Ephebophilia: adult sexual attraction to postpubescent adolescents, typically ages 15-19; a chronophilia category between hebephilia and teleiophilia, not a DSM-5 or ICD-11 diagnosis.
Ephedra (plant)
Ephedra (ma huang, 麻黄) is a genus of about 70 gymnosperm shrubs in Gnetales, with Gnetum and Welwitschia its closest living relatives; source of ephedrine alkaloids, banned in US supplements since 2004, with a fossil record over 110 million years old.
Ephedrine
Ephedrine, from Ephedra sinica (ma huang, Mahuang), is a sympathomimetic plant alkaloid isolated by Nagai in 1885, rediscovered by Chen and Schmidt, once a leading oral asthma drug, now restricted as a methamphetamine precursor.
Ephemera
Ephemera: transitory printed or written items such as tickets, posters, and receipts created for short-term use and meant to be discarded, now collected and archived as primary evidence of everyday life, from the Greek ephēmeros, "lasting only a day."
Ephemerality
Ephemerality: the quality of transience or insubstantiality, from Greek ephêmeros. Covers Buddhist momentariness, Heraclitean flux, Japanese mujō, persistence metaphysics, and ephemeral design in social media and digital preservation.
Ephemeridae
Ephemeridae, the burrowing mayflies, is a family of Ephemeroptera in the superfamily Ephemeroidea, with about 96 species in 7 genera including Ephemera and Hexagenia; tusked nymphs burrow in sediments and serve as water-quality bioindicators.
Ephemeris
An ephemeris (plural: ephemerides), also called astronomical tables, is a table of computed positions and velocities of an orbiting body, such as a planet, asteroid, or spacecraft, at specific times.
Ephemeris belli Troiani
Ephemeris belli Troiani is a Latin narrative of the Trojan War attributed to Dictys of Crete, a Greek companion of Idomeneus, translated by Lucius Septimius.
Ephemeris time
Ephemeris time was a theoretically uniform time scale adopted by the International Astronomical Union in 1952; its ephemeris second was the SI second from 1960 until atomic time replaced it.
Ephemeroptera
Ephemeroptera, the mayflies, an order of Palaeoptera insects with about 3,281 described species; aquatic nymphs with gills, a unique winged subimago stage, and adults living 1-2 days.
