Trophozoites
|
D053058 |
[Cells or feeding stage in the life cycle of sporozoan protozoa. In the malarial parasite, the trophozoite develops from the MEROZOITE and then splits into the SCHIZONT. Trophozoites that are left over from cell division can go on to form gametocytes.

Tropical Climate
|
D014329 |
[A climate which is typical of equatorial and tropical regions, i.e., one with continually high temperatures with considerable precipitation, at least during part of the year. (McGraw-Hill Dictionary of Scientific and Technical Terms, 4th ed)

Tropical Medicine
|
D014330 |
[The branch of medicine concerned with diseases, mainly of parasitic origin, common in tropical and subtropical regions.

Tropicamide
|
D014331 |
[One of the MUSCARINIC ANTAGONISTS with pharmacologic action similar to ATROPINE and used mainly as an ophthalmic parasympatholytic or mydriatic.

Tropisetron
|
D000077526 |
[An indole derivative and 5-HT3 RECEPTOR antagonist that is used for the prevention of nausea and vomiting.

|
Tropism
|
D018523 |
[The directional growth of an organism in response to an external stimulus such as light, touch, or gravity. Growth towards the stimulus is a positive tropism; growth away from the stimulus is a negative tropism. (From Concise Dictionary of Biology, 1990)

Tropocollagen
|
D014332 |
[The molecular unit of collagen fibrils that consist of repeating three-stranded polypeptide units arranged head to tail in parallel bundles. It is a right-handed triple helix composed of 2 polypeptide chains. It is rich in glycine, proline, hydroxyproline, and hydroxylysine.

|
Tropoelastin
|
D014333 |
[A salt-soluble precursor of elastin. Lysyl oxidase is instrumental in converting it to elastin in connective tissue.

|
Tropolone
|
D014334 |
[A seven-membered aromatic ring compound. It is structurally related to a number of naturally occurring antifungal compounds (ANTIFUNGAL AGENTS).

|
Tropomodulin
|
D051348 |
[An actin capping protein that binds to the pointed-end of ACTIN. It functions in the presence of TROPOMYOSIN to inhibit microfilament elongation.
] |
|
Tropomyosin
|
D014335 |
[A protein found in the thin filaments of muscle fibers. It inhibits contraction of the muscle unless its position is modified by TROPONIN.
] |
|
Troponin
|
D014336 |
[One of the minor protein components of skeletal and cardiac muscles. It functions as the calcium-binding component in a complex with BETA-TROPOMYOSIN; ACTIN; and MYOSIN and confers calcium sensitivity to the cross-linked actin and myosin filaments. Troponin itself is a complex of three regulatory proteins (TROPONIN C; TROPONIN I; and TROPONIN T).
] |
|
Troponin C
|
D019209 |
[A TROPONIN complex subunit that binds calcium and help regulate calcium-dependent muscle contraction. There are two troponin C subtypes: troponin C1 and C2. Troponin C1 is skeletal and cardiac type whereas troponin C2 is skeletal type. Troponin C1 is a BIOMARKER for damaged or injured CARDIAC MYOCYTES and mutations in troponin C1 gene are associated with FAMILIAL HYPERTROPHIC CARDIOMYOPATHY.
] |
|
Troponin I
|
D019210 |
[A TROPONIN complex subunit that inhibits ACTOMYOSIN ATPASE activity thereby disrupting ACTIN and MYOSIN interaction. There are three troponin I subtypes: troponin I1, I2 and I3. Troponin I3 is cardiac-specific whereas troponin I1 and I2 are skeletal subtypes. Troponin I3 is a BIOMARKER for damaged or injured CARDIAC MYOCYTES and mutations in troponin I3 gene are associated with FAMILIAL HYPERTROPHIC CARDIOMYOPATHY.
] |
|
Troponin T
|
D020107 |
[A TROPONIN complex subunit that binds to TROPOMYOSIN. There are three troponin T subtypes: troponin T1, T2 and T3. Troponin T2 is cardiac-specific whereas troponin T2 and T3 are skeletal subtypes. Troponin T2 is a BIOMARKER for damaged or injured CARDIAC MYOCYTES and mutations in troponin T2 gene are associated with FAMILIAL HYPERTROPHIC CARDIOMYOPATHY.

Trout
|
D014337 |
[A genus of fish with the common name chars.
, Various fish of the family SALMONIDAE, usually smaller than salmon. They are mostly restricted to cool clear freshwater. Some are anadromous. They are highly regarded for their handsome colors, rich well-flavored flesh, and gameness as an angling fish. The genera Salvelinus, Salmo, and ONCORHYNCHUS have been introduced virtually throughout the world.

Truncated Hemoglobins
|
D054793 |
[A family of hemoglobin-like proteins found in BACTERIA; PLANTS; and unicellular eukaryotes. Truncated hemoglobins are distantly related to vertebrate hemoglobins and are typically shorter than vertebrate hemoglobins by 20-40 residues.

|
Truncus Arteriosus
|
D014338 |
[The arterial trunk arising from the fetal heart. During development, it divides into AORTA and the PULMONARY ARTERY.
] |
|
Truncus Arteriosus, Persistent
|
D014339 |
[A congenital anomaly caused by the failed development of TRUNCUS ARTERIOSUS into separate AORTA and PULMONARY ARTERY. It is characterized by a single arterial trunk that forms the outlet for both HEART VENTRICLES and gives rise to the systemic, pulmonary, and coronary arteries. It is always accompanied by a ventricular septal defect.
