Thoracic Surgical Procedures
|
D019616 |
[Surgery performed on the thoracic organs, most commonly the lungs and the heart.
] |
|
Thoracic Vertebrae
|
D013904 |
[A group of twelve VERTEBRAE connected to the ribs that support the upper trunk region.
] |
|
Thoracic Wall
|
D035441 |
[The outer margins of the thorax containing SKIN, deep FASCIA; THORACIC VERTEBRAE; RIBS; STERNUM; and MUSCLES.
] |
|
Thoracica
|
D001468 |
[A superorder of marine CRUSTACEA, free swimming in the larval state, but permanently fixed as adults. There are some 800 described species, grouped in several genera, and comprising of two major orders of barnacles: stalked (Pedunculata) and sessile (Sessilia).
, Genus in the family Balanidae, order Sessilia.

Thoracoplasty
|
D013905 |
[Surgical removal of ribs, allowing the chest wall to move inward and collapse a diseased lung. (Dorland, 28th ed)

|
Thoracoscopes
|
D020708 |
[Endoscopes for examining the pleural cavity.
] |
|
Thoracoscopy
|
D013906 |
[Endoscopic examination, therapy or surgery of the pleural cavity.
] |
|
Thoracostomy
|
D013907 |
[Surgical procedure involving the creation of an opening (stoma) into the chest cavity for drainage; used in the treatment of PLEURAL EFFUSION; PNEUMOTHORAX; HEMOTHORAX; and EMPYEMA.
] |
|
Thoracotomy
|
D013908 |
[Surgical incision into the chest wall.
] |
|
Thorax
|
D013909 |
[The upper part of the trunk between the NECK and the ABDOMEN. It contains the chief organs of the circulatory and respiratory systems. (From Stedman, 25th ed)

|
Thorium
|
D013910 |
[A radioactive element of the actinide series of metals. It has an atomic symbol Th, atomic number 90, and atomic weight 232.04. It is used as fuel in nuclear reactors to produce fissionable uranium isotopes. Because of its radioopacity, various thorium compounds are used to facilitate visualization in roentgenography.

|
Thorium Compounds
|
D017970 |
[Inorganic compounds that contain thorium as an integral part of the molecule.
] |
|
Thorium Dioxide
|
D013911 |
[Thorium oxide (ThO2). A radiographic contrast agent that was used in the early 1930s through about 1954. High rates of mortality have been linked to its use and it has been shown to cause liver cancer.
] |
|
Threonine
|
D013912 |
[An essential amino acid occurring naturally in the L-form, which is the active form. It is found in eggs, milk, gelatin, and other proteins.
] |
|
Threonine Dehydratase
|
D013913 |
[A pyridoxal-phosphate protein that catalyzes the deamination of THREONINE to 2-ketobutyrate and AMMONIA. The role of this enzyme can be biosynthetic or biodegradative. In the former role it supplies 2-ketobutyrate required for ISOLEUCINE biosynthesis, while in the latter it is only involved in the breakdown of threonine to supply energy. This enzyme was formerly listed as EC 4.2.1.16.

|
Threonine-tRNA Ligase
|
D013914 |
[An enzyme that activates threonine with its specific transfer RNA. EC 6.1.1.3.
] |
|
Threshold Limit Values
|
D020711 |
[Standards for limiting worker exposure to airborne contaminants. They are the maximum concentration in air at which it is believed that a particular substance will not produce adverse health effects with repeated daily exposure. It can be a time-weighted average (TLV-TWA), a short-term value (TLV-STEL), or an instantaneous value (TLV-Ceiling). They are expressed either as parts per million (ppm) or milligram per cubic meter (mg/m3).

|
Thrombasthenia
|
D013915 |
[A congenital bleeding disorder with prolonged bleeding time, absence of aggregation of platelets in response to most agents, especially ADP, and impaired or absent clot retraction. Platelet membranes are deficient in or have a defect in the glycoprotein IIb-IIIa complex (PLATELET GLYCOPROTEIN GPIIB-IIIA COMPLEX).
] |
|
Thrombectomy
|
D017131 |
[Surgical removal of an obstructing clot or foreign material from a blood vessel at the point of its formation. Removal of a clot arising from a distant site is called EMBOLECTOMY.
] |
|
Thrombelastography
|
D013916 |
[Use of a thrombelastograph, which provides a continuous graphic record of the physical shape of a clot during fibrin formation and subsequent lysis.
