Asperger syndrome
Asperger syndrome, also called Asperger's, was a diagnosis for autistic people without learning disability, described by Hans Asperger in 1944 and named by Lorna Wing in 1981; retired into autism spectrum disorder by DSM-5 (2013) and ICD-11 (2019).
Aspergillosis
Aspergillosis, disease from inhaled Aspergillus mold spores; forms include ABPA, chronic pulmonary, and invasive aspergillosis; A. fumigatus is the main cause; triazoles treat it; azole resistance is emerging.
Aspergillus
Aspergillus: genus of molds defined by foot-cell conidiophores; 453 accepted species in six subgenera and 27 sections; includes pathogen A. fumigatus, food fermenter A. oryzae, and enzyme producer A. niger.
Aspergillus and Penicillium
Aspergillus and Penicillium are two sister genera of mold fungi in the family Aspergillaceae, together making up more than 90% of that family's described species.
Aspergillus bronchitis
Aspergillus bronchitis (ICD-11 1F20.14) is a chronic superficial infection of the larger airways by Aspergillus, mainly in bronchiectasis and cystic fibrosis patients without major immunocompromise, diagnosed by repeated positive cultures or PCR, elevated Aspergillus IgG, and exclusion of ABPA and CPA.
Aspergillus flavus
Aspergillus flavus, a widespread mold and second-leading cause of invasive aspergillosis, produces aflatoxins including aflatoxin B1, among the strongest natural carcinogens, contaminating maize, nuts, and cereals; non-aflatoxigenic strains are used as biocontrol.
Aspergillus fumigatus
Aspergillus fumigatus, a ubiquitous thermotolerant saprophytic mold and leading cause of aspergillosis; WHO critical-priority pathogen; azole resistance via cyp51A mutations and agricultural fungicide selection.
Aspergillus galactomannan antigen test
The Aspergillus galactomannan antigen test, also called Galactomannan Antigen, is a sandwich immunoassay detecting Aspergillus antigen in serum or lung fluid to diagnose invasive aspergillosis in immunocompromised patients.
Aspergillus nidulans
Aspergillus nidulans (teleomorph Emericella nidulans) is a haploid homothallic filamentous fungus, the genetic model of the genus Aspergillus, established by Pontecorvo in 1953, with a sexual cycle, parasexuality, and a 2005 sequenced genome.
Aspergillus niger
Aspergillus niger (black mold, section Nigri) is the industrial fungus behind most citric acid and many food enzymes, GRAS in selected strains, with an 8-chromosome 33.9 Mb genome, but some isolates make ochratoxin A and fumonisin B2.
Aspergillus ochraceus
Aspergillus ochraceus, an Aspergillus subgen. Circumdati mold (K. Wilhelm 1877), source of the first ochratoxin A isolation in 1965; yellow-spored, ~37 Mb genome, otaA-D OTA gene cluster, also a lignin-degrading enzyme producer. Not to be confused with A. westerdijkiae.
Aspergillus oryzae
Aspergillus oryzae, the koji mold (麹菌), is a domesticated filamentous fungus used in sake, soy sauce, and miso fermentation; it is a non-aflatoxin-producing close relative of Aspergillus flavus and a major industrial enzyme producer.
Aspergillus oryzae and Rhizopus oryzae carbohydrase and protease preparations
Aspergillus oryzae and Rhizopus oryzae carbohydrase and protease preparations: fungal enzyme mixtures used as food processing aids; A. oryzae carbohydrase and protease are GRAS since early 1960s FDA letters, R. oryzae carbohydrase is 21 CFR 173.130 for dextrose.
Aspergillus otomycosis
Aspergillus otomycosis (アスペルギルス性耳真菌症), ICD-11 1F20.10, is a non-invasive superficial Aspergillus infection of the external ear canal, mainly A. niger and A. tubingensis, treated by canal cleansing plus topical antifungals or boric acid.
Aspergillus parasiticus
Aspergillus parasiticus (Speare, 1912) is an aflatoxin-producing Aspergillus fungus in section Flavi that makes both B and G aflatoxins but never cyclopiazonic acid, contaminating crops such as peanuts, maize, and cottonseed.
Aspergillus wentii
Aspergillus wentii (Wehmer, 1896) is a mold in Aspergillus subgenus/section Cremei, used for industrial enzymes, koji and soy-sauce fermentation, citric and L-malic acid production, and studied for 97 secondary metabolites.
Aspergillus, section Flavi
Aspergillus, section Flavi, is a group of closely related molds, most famous for producing aflatoxins, group 1 carcinogens, and for including the main aflatoxin producer, Aspergillus flavus, alongside the domesticated Aspergillus oryzae.
ASPH
ASPH (HGNC:757, aspartate beta-hydroxylase) is a human chromosome 8q12.3 gene encoding an Fe(II)/2-oxoglutarate dioxygenase that hydroxylates Asp/Asn in EGF-like domains; its truncated isoforms junctin and junctate regulate calcium handling, and biallelic mutations cause Traboulsi syndrome.
Asphalt
Asphalt is a dark, cement-like material obtained from petroleum processing, in which bitumens predominate; it is used primarily for road construction, either as the binder in pavement mixtures or in refined products.
Asphalt 8: Airborne
Asphalt 8: Airborne is a 2013 arcade racing game by Gameloft Barcelona, eighth in the Asphalt series, known for aerial-stunt gameplay on a new physics engine, a 91 Metacritic score, 300 million downloads, and updates continuing into 2025.
Asphalt concrete
Asphalt concrete, also known as hot mix asphalt, is a composite paving material of mineral aggregate bound with asphalt binder, placed hot and compacted for roads, parking areas, and airfields.
Asphalt rubber binder
Asphalt rubber binder, also called asphalt-rubber, is a paving binder made by blending ground recycled tire rubber into hot asphalt cement until the particles swell, used in chip seals and hot mix asphalt.
Asphalt shingle
An asphalt shingle is a lightweight roofing unit of asphalt-coated mat surfaced with mineral granules, the dominant roof covering on over 80 percent of US homes.
Asphalts
Asphalts, EU ID 414, is a non-approved entry in the EU Pesticides Database with no CAS number and a default MRL of 0.01 mg/kg; historically mixed with cutback asphalts for roadside weed control.
Aspheric lens
An aspheric lens, also called an asphere, is a lens whose surface deviates from a sphere to eliminate spherical aberration, allowing fewer elements and more compact systems.
Asphodel Meadows
Asphodel Meadows (ἀσφοδελὸς λειμών, asphodelos leimon), the Homeric Greek underworld meadow where ordinary shades of the dead dwell (Odyssey 11, 24), later the middle realm between Elysium and Tartarus; etymology and tone remain debated.
