Valine; vanadium; vision; volt; volume.
A membranous fold in a canal or passage, which prevents the reflux of the contents passing through it.
Valine; vanadium; vision; volt; volume.
The V2-tail is a fragment of the V2 receptor that contains only the last 130 amino acids starting at position 243 within the receptor sequence (T. Schoneberg).
1. Not clearly or explicitly expressed or stated.
2. Indefinite or indistinct in nature or character, as ideas, feelings, etc.
3. Not clear or distinct to the sight or any other sense; perceptible or recognizable only in an indefinite way.
4. Not definitely established, determined, confirmed, or known; uncertain.
5. (Of persons) not clear or definite in thought, understanding, or expression.
6. (Of the eyes, expression, etc.) showing lack of clear perception or understanding.
Vasopressin V(2) receptor.
Vasopressin-2 receptor.
See "nervus vagus."
As V, symbol for valine , vanadium , volt , volume , and vision .
As V, symbol for voltage and volume .
As v, abbreviation for L. vena , vein; velocity.
As v, symbol for velocity and voltage .
Vasopressin-2 receptor gene.
1. A positive number that represents the combining power of an element in a chemical compound, i.e., the number of bonds each atom of that element makes with other atoms. In this most general sense "valence" has been superseded by the concept "oxidation number." However, "valence" is still used to indicate (a) the number of covalent bonds formed by an atom in a covalent compound or (b) the charge on a monatomic or polyatomic molecule.
2. In immunology, the number of antigen binding sites possessed by an antibody molecule, two per immunoglobulin monomer, or the number of antigenic determinants possessed by an antigen, usually a large number.
As V, symbol for valine , vanadium , volt , volume , and vision .
As V, symbol for voltage and volume .
As v, abbreviation for L. vena , vein; velocity.
As v, symbol for velocity and voltage .
Vasopressin-2 receptors.
See "valence."
Vasopressin-1.
1. A prime mover of V2.
2. In pharmacology, a drug that has affinity for and stimulates physiologic activity at cell receptors normally stimulated by naturally occurring substances.
An essential amino acid, alpha-amino-isovalerianic acid, produced by the digestion or hydrolytic decomposition of proteins; it is essential for optimal growth in infants and for nitrogen equilibrium in human adults.
A protein that acts as a receptor for arginine vasopressin. It belongs to the subfamily of G-protein coupled receptors.
The N-terminal portion, composing one homology region, of an immunoglobulin heavy chain. See variable region .
Primary coccidioidomycosis.
A protein that acts as a receptor for arginine vasopressin. It belongs to the subfamily of G-protein coupled receptors.
Inoculated with vaccine for the purpose of producing immunity.
1. A measure of worth or efficiency.
2. A quantitative measurement of the activity, concentration, or some other quality of a substance.
Vasopressin-1a receptor.
The introduction of vaccine into the body for the purpose of inducing immunity. Coined originally to apply to the injection of smallpox vaccine, the term has come to mean any immunizing procedure in which vaccine is injected.
Aortic valve: a valve composed of three semilunar cusps or segments (semilunar cusps of aortic valve), guarding the aortic orifice in the left ventricle of the heart; it prevents backflow into the left ventricle.
Vasopressin-1a receptors.
A suspension of attenuated or killed microorganisms (bacteria, viruses, or rickettsiae), or of antigenic proteins derived from them, administered for the prevention, amelioration, or treatment of infectious diseases. The term is derived from Latin vaccinus pertaining to cows, from vacca cow (so named from the use of cowpox virus inoculation for immunization against smallpox).
Right atrioventricular valve: the valve between the right atrium and right ventricle of the heart; it usually has three cusps (anterior, posterior, and septal), but additional small cusps may be present. Called also valva tricuspidalis and tricuspid valve .
Vasopressin-2. See vasopressin-2 gene and vasopressin-2 receptor.
The cutaneous and sometimes systemic reactions associated with vaccination with smallpox vaccine.
Left atrioventricular valve: the valve between the left atrium and left ventricle of the heart; it usually has two cusps (anterior and posterior), but additional small cusps may be present. Called also valva mitralis and mitral valve .
Arginine vasopressin (AVP) receptor type 2.
1. A space devoid of air or of other gas; a space from which the air has been exhausted.
2. Void, gap.
3. Vacuum cleaner.
Valva atrioventricularis sinistra .
See under receptor .
A glass tube from which the air has been exhausted to a high degree of vacuum.
Valva trunci pulmonalis .
The molecular structure within a cell or on the surface to which the antidiuretic hormone, arginine vasopressin binds.
Vagus nerve fibers; the vagus nerve supplies sensory fibers to the ear, tongue, pharynx, and larynx; motor fibers to the pharynx, larynx, and esophagus; and parasympathetic and visceral afferent fibers to thoracic and abdominal viscera.
Valva atrioventricularis dextra .
See under "receptor."
1. A sheath, or sheath-like structure; used as a general term in anatomical nomenclature.
2. The canal in the female, extending from the vulva to the cervix uteri, which receives the penis in copulation.
Valve of pulmonary trunk: a valve composed of three semilunar cusps or segments (semilunar cusps of pulmonary valve), guarding the pulmonary orifice in the right ventricle of the heart; it prevents backflow of blood into the right ventricle. Called also pulmonary or pulmonic valve and valva pulmonaria .
See blockade.
1. Of the nature of a sheath; ensheathing.
2. Pertaining to the vagina.
3. Pertaining to the tunica vaginalis testis.
A membranous fold in a canal or passage, which prevents the reflux of the contents passing through it.
