Design, development, manufacture, and operation of heavier-than-air AIRCRAFT.
A genus of RNA viruses in the family BIRNAVIRIDAE infecting birds. It is transmitted horizontally with no known vectors. The type species is INFECTIOUS BURSAL DISEASE VIRUS.
A plant genus of the family Acanthaceae. Members contain NAPHTHOQUINONES. Black mangroves (common name for the genus) are distinguished from other mangroves by their spike-like aerial roots called pneumatophores that project from the soil or water surrounding the plants.
A specific protein in egg albumin that interacts with BIOTIN to render it unavailable to mammals, thereby producing biotin deficiency.
A genus of HEPADNAVIRIDAE infecting birds but rarely causing clinical problems. Transmission is predominantly vertical. HEPATITIS B VIRUS, DUCK is the type species.
A genus of the family POXVIRIDAE, subfamily CHORDOPOXVIRINAE, comprising bird poxviruses. The type species is FOWLPOX VIRUS. Transmission is mechanical by ARTHROPODS.
A condition due to a deficiency of one or more essential vitamins. (Dorland, 27th ed)

A genus in the subfamily PARAMYXOVIRINAE, family PARAMYXOVIRIDAE, causing disease in domestic fowl. There are many species, the most well-known being avian paramyxovirus 1 (NEWCASTLE DISEASE VIRUS).
Infections with viruses of the genus AVULAVIRUS, family PARAMYXOVIRIDAE. This includes NEWCASTLE DISEASE and other infections of domestic fowl.
The act of taking account of an object or state of affairs. It does not imply assessment of, nor attention to the qualities or nature of the object.
Culture of an isolated organism free from any other associating or contaminating organisms.
The distance between the anterior and posterior poles of the eye, measured either by ULTRASONOGRAPHY or by partial coherence interferometry.
Area of the human body underneath the SHOULDER JOINT, also known as the armpit or underarm.
The continuation of the subclavian artery; it distributes over the upper limb, axilla, chest and shoulder.
The venous trunk of the upper limb; a continuation of the basilar and brachial veins running from the lower border of the teres major muscle to the outer border of the first rib where it becomes the subclavian vein.
An extra-anatomic method of surgical revascularization in which the AXILLARY ARTERY is anastomosed to FEMORAL ARTERY.
A scaffolding protein that is a critical component of the axin signaling complex which binds to ADENOMATOUS POLYPOSIS COLI PROTEIN; GLYCOGEN SYNTHASE KINASE 3; and CASEIN KINASE I.
A specific complex of WNT SIGNALING PATHWAY proteins that mediates the phosphorylation-dependent destruction of cytosolic BETA-CATENIN. The complex is disrupted by cell surface binding of WNT PROTEINS, which allows beta-catenin levels to rise to the point where they migrate to the CELL NUCLEUS and activate transcription.

A genus of SPONGES in the family Axinellidae, comprised of a choanosomal skeleton differentiated in the axial and extra-axial region. The type species is Axinella polypoides.
The second cervical vertebra.
The directed transport of ORGANELLES and molecules along nerve cell AXONS. Transport can be anterograde (from the cell body) or retrograde (toward the cell body). (Alberts et al., Molecular Biology of the Cell, 3d ed, pG3)
Dyneins that are responsible for ciliary and flagellar beating.
A bundle of MICROTUBULES and MICROTUBULE-ASSOCIATED PROTEINS forming the core of each CILIUM or FLAGELLUM. In most eukaryotic cilia or flagella, an axoneme shaft has 20 microtubules arranged in nine doublets and two singlets.
Nerve fibers that are capable of rapidly conducting impulses away from the neuron cell body.
Transection or severing of an axon. This type of denervation is used often in experimental studies on neuronal physiology and neuronal death or survival, toward an understanding of nervous system disease.
Organic chemicals where carbon atoms have been replaced by nitrogen atoms.
Bicyclic bridged compounds that contain a nitrogen which has three bonds. The nomenclature indicates the number of atoms in each path around the rings, such as [2.2.2] for three equal length paths. Some members are TROPANES and BETA LACTAMS.
A pyrimidine analogue that inhibits DNA methyltransferase, impairing DNA methylation. It is also an antimetabolite of cytidine, incorporated primarily into RNA. Azacytidine has been used as an antineoplastic agent.
Diaza derivative of cholesterol which acts as a hypocholesteremic agent by blocking delta-24-reductase, which causes the accumulation of desmosterol.
