An anti-inflammatory agent used in the treatment of rheumatoid arthritis. It also has uricosuric properties and has been used to treat gout.
The largest subunit of the anaphase-promoting complex. It acts primarily as a scaffold for the proper organization and arrangement of subunits. The C-terminal region of Apc1 contains a series of tandem amino acid repeats that are also seen in the 26S proteasome regulatory particle, and may assist with forming and stabilizing protein-protein interactions.
Apc10 is necessary for coactivator-dependent substrate recognition by the anaphase-promoting complex-cyclosome. It binds the Apc2 subunit, which is a part of the catalytic core, and interacts with coactivators Cdh1 or Cdc20 to recruit substrates to the complex.
Together with the Apc2 subunit, forms the catalytic core of the E3 ubiquitin ligase, anaphase-promoting complex-cyclosome. It has a RING H2 domain which interacts with the cullin domain of Apc2. Apc11 also interacts with the E2 ubiquitin ligases involved in APC-C ubiquitination reactions.
Together with the Apc11 subunit, forms the catalytic core of the E3 ubiquitin ligase anaphase-promoting complex (APC-C). Its N-terminus has cullin domains which associate with the RING FINGER DOMAINS of Apc11. Apc2 also interacts with the E2 ubiquitin ligases involved in APC-C ubiquitination reactions.
A highly evolutionarily conserved subunit of the anaphase-promoting complex (APC-C) containing multiple 34-amino-acid tetratricopeptide repeats. These domains, also found in Apc subunits 6, 7, and 8, have been shown to mediate protein-protein interactions, suggesting that Apc3 may assist in coordinating the juxtaposition of the catalytic and substrate recognition module subunits relative to co-activators and APC-C inhibitors.
A subunit of the anaphase-promoting complex whose primary function is to provide structural support for the catalytic and substrate-recognition modules of the complex. Apc4, along with Apc5, tethers the tetratricopeptide-coactivator binding subcomplex to the main structural subunit, Apc1.

A highly conserved subunit of the anaphase-promoting complex (APC-C) containing multiple 34 amino acid tetratricopeptide repeats. These domains, also found in Apc3, Apc7, and Apc8, have been shown to mediate protein-protein interactions, suggesting that Apc6 may assist in coordinating the juxtaposition of the catalytic and substrate recognition module subunits relative to coactivators and APC-C inhibitors.

Endodontic procedure performed to induce TOOTH APEX barrier development. ROOT CANAL FILLING MATERIALS are used to repair open apex or DENTAL PULP NECROSIS in an immature tooth. CALCIUM HYDROXIDE and mineral trioxide aggregate are commonly used as the filling materials.
A method, developed by Dr. Virginia Apgar, to evaluate a newborn's adjustment to extrauterine life. Five items - heart rate, respiratory effort, muscle tone, reflex irritability, and color - are evaluated 60 seconds after birth and again five minutes later on a scale from 0-2, 0 being the lowest, 2 being normal. The five numbers are added for the Apgar score. A score of 0-3 represents severe distress, 4-7 indicates moderate distress, and a score of 7-10 predicts an absence of difficulty in adjusting to extrauterine life.

Absence of crystalline lens totally or partially from field of vision, from any cause except after cataract extraction. Aphakia is mainly congenital or as result of LENS DISLOCATION AND SUBLUXATION.
Absence of the crystalline lens resulting from cataract extraction.
A form-genus of planktonic CYANOBACTERIA in the order Nostocales.
A genus of OOMYCETES in the family Saprolegniaceae. It causes root rot in plants and is also a pathogen of FISHES.
A cognitive disorder marked by an impaired ability to comprehend or express language in its written or spoken form. This condition is caused by diseases which affect the language areas of the dominant hemisphere. Clinical features are used to classify the various subtypes of this condition. General categories include receptive, expressive, and mixed forms of aphasia.
An aphasia characterized by impairment of expressive LANGUAGE (speech, writing, signs) and relative preservation of receptive language abilities (i.e., comprehension). This condition is caused by lesions of the motor association cortex in the FRONTAL LOBE (BROCA AREA and adjacent cortical and white matter regions).
A type of fluent aphasia characterized by an impaired ability to repeat one and two word phrases, despite retained comprehension. This condition is associated with dominant hemisphere lesions involving the arcuate fasciculus (a white matter projection between Broca's and Wernicke's areas) and adjacent structures. Like patients with Wernicke aphasia (APHASIA, WERNICKE), patients with conduction aphasia are fluent but commit paraphasic errors during attempts at written and oral forms of communication. (From Adams et al., Principles of Neurology, 6th ed, p482; Brain and Bannister, Clinical Neurology, 7th ed, p142; Kandel et al., Principles of Neural Science, 3d ed, p848)
A progressive form of dementia characterized by the global loss of language abilities and initial preservation of other cognitive functions. Fluent and nonfluent subtypes have been described. Eventually a pattern of global cognitive dysfunction, similar to ALZHEIMER DISEASE, emerges. Pathologically, there are no Alzheimer or PICK DISEASE like changes, however, spongiform changes of cortical layers II and III are present in the TEMPORAL LOBE and FRONTAL LOBE. (From Brain 1998 Jan;121(Pt 1):115-26)
Impairment in the comprehension of speech and meaning of words, both spoken and written, and of the meanings conveyed by their grammatical relationships in sentences. It is caused by lesions that primarily affect Wernicke's area, which lies in the posterior perisylvian region of the temporal lobe of the dominant hemisphere. (From Brain and Bannister, Clinical Neurology, 7th ed, p141; Kandel et al., Principles of Neural Science, 3d ed, p846)
An antiviral antibiotic produced by Cephalosporium aphidicola and other fungi. It inhibits the growth of eukaryotic cells and certain animal viruses by selectively inhibiting the cellular replication of DNA polymerase II or the viral-induced DNA polymerases. The drug may be useful for controlling excessive cell proliferation in patients with cancer, psoriasis or other dermatitis with little or no adverse effect upon non-multiplying cells.

A large plant family in the order Apiales, also known as Umbelliferae. Most are aromatic herbs with alternate, feather-divided leaves that are sheathed at the base. The flowers often form a conspicuous flat-topped umbel. Each small individual flower is usually bisexual, with five sepals, five petals, and an enlarged disk at the base of the style. The fruits are ridged and are composed of two parts that split open at maturity.
