All terms in NCIT

Label	Id	Description
Tn Antigen	NCIT_C112044	[A protein antigen that is comprised of the monosaccharide N-acetylgalactosamine (GalNAc) bound to serine or threonine by O-linked glycosylation. Aberrant expression of Tn antigen by all blood cell lineages is associated with a rare hematological disorder called Tn-syndrome. Increased expression of this monosaccharide modification is also associated with some cancers and this antigen is being investigated for use as either a biomarker or therapeutic target for these associated malignancies.]
Tumor Antigen	NCIT_C912	[1. antigens that may be frequently associated with tumors or may be specifically found on tumor cells of the same origin (tumor specific); 2. tumor antigens may also be associated with replication and transformation by certain DNA tumor viruses, including adenoviruses and papovaviruses. Neoantigens. Any immunologically detectable marker whose presence or amount indicates the presence of a tumor.]
Replication Competent Retrovirus	NCIT_C112045	[A retroviral vector that contains all the genes that are required for virion synthesis and is able to propagate after the host is infected.]
Retroviral Vector	NCIT_C2463	[Any one of the recombinant retroviruses (RNA viruses) designed for gene transfer applications to deliver genetic material of interest into cells. These retroviral vectors are replication defective and have decreased immunogenicity. They are able to efficiently infect dividing cells, and the exogenous genetic material is integrated into the genome of the target cell. Thereby, the expression of the exogenous gene is stable instead of transient as in the case of adenoviral vectors.]
Anthocyanin	NCIT_C112040	[A flavonoid that is a glycoside derivative of anthocyanidin. They are water-soluble plant pigments that exhibit bright coloration. Their color is dependent on the pH of the solvent; therefore, these polyphenols are used as pH indicators.]
Flavonoid	NCIT_C1745	[One of a number of chemical compounds found in certain fruits, vegetables and seeds with antioxidant properties and potential antineoplastic properties. As polyphenolic, soluble plant pigments, flavonoids are usually subdivided into 5 subgroups flavonols, flavones, flavonones, flavan-3-ols, anthocyanidins. Although not considered essential nutrients, some flavonoids may be beneficial to health by strengthening and protecting blood vessels and connective tissue and acting as anti-inflammatory, antihistaminic, and antiviral agents. As antioxidants, some flavonoids may protect lipids from oxidative damage or retard the formation of cataracts. (NCI04)]
Stationary Digital Chest Tomosynthesis	NCIT_C126698	[Stationary digital tomography used to image structures in the thoracic cavity.]
Stationary Digital Tomosynthesis	NCIT_C126696	[Digital tomosynthesis that uses an array of x-ray sources to obtain cross-sectional images of an object for 3-D image construction. Stationary digital tomosynthesis eliminates the blur associated with a moving x-ray source and also decreases the time needed to obtain the images.]
Digital Chest Tomosynthesis	NCIT_C126697	[Digital tomosynthesis used to image structures in the thoracic cavity.]
BCG Tokyo-172 Strain Solution	NCIT_C126694	[A solution containing an attenuated, live culture preparation of the bacillus Calmette-Guerin (BCG) strain of Mycobacterium bovis obtained from the Pasteur Institute in 1924, with potential immunostimulating and antineoplastic activities. Although the precise mechanism of action is unknown, upon intravesical instillation through a catheter, the attenuated, live BCG bacteria in the BCG Tokyo-172 strain solution come into direct contact with the bladder wall and elicits a local, multifaceted immune response against the BCG antigens, which kills the bladder cancer cells. Previous vaccination with a systemic BCG vaccine may enhance the immune system's response against the BCG antigens.]
Digital Tomosynthesis	NCIT_C126695	[An imaging technique in which multiple X-rays of an object are take from a discrete number of angles. These cross-sectional images are used to reconstruct 3-D images of the object being scanned. Tomosynthesis differs from computed tomography because the range of angles used is less than 360 degrees, as used in computed tomography.]
Diagnostic Imaging	NCIT_C16502	[Any method that uses a visual display of structural or functional patterns of organs or tissues for diagnostic evaluation.]
X-Ray Imaging	NCIT_C38101	[A radiographic procedure using the emission of x-rays to form an image of the structure penetrated by the radiation.]
Recent Thymic Emigrant	NCIT_C112039	[A T-lymphocyte that has completed intrathymic development and has exited the thymus. These cells are the youngest peripheral T-lymphocytes and migrate to secondary lymphoid organs where they slowly mature to become naive T-cells.]
Peripheral (Post-Thymic) T-Lymphocyte	NCIT_C38434
Percent Recovered Infinity Predicted	NCIT_C112035	[The percentage of the recovered administered dose extrapolated to infinity, calculated using the predicted value of the last non-zero concentration.]
Percent Recovered	NCIT_C85777	[The percentage of the total dose that is recovered.]
Dengue Virus	NCIT_C112036	[A species of enveloped and spherical viruses with a capsid with T=3 icosahedral symmetry in the Flaviviridae family and Flavivirus genus. The genome is composed of non-segmented, single-stranded, positive-sense RNA. Dengue viruses are found in non-human primates and humans and cause dengue fever in humans. Dengue viruses are transmitted mainly via the bite of infected mosquitoes of the genus Aedes.]
Flavivirus	NCIT_C14208	[A genus of enveloped viruses with a genome consisting of a single molecule of linear positive-sense single-stranded RNA.]
CDISC SDTM Device Tracking and Disposition Event Dictionary Derived Term Terminology	NCIT_C112037	[Terminology associated with the Device Tracking and Disposition Event Dictionary Derived Term codelist of the Clinical Data Interchange Standards Consortium (CDISC) Study Data Tabulation Model (SDTM).]
