Trochlear Nerve
|
D014321 |
[The 4th cranial nerve. The trochlear nerve carries the motor innervation of the superior oblique muscles of the eye.

Trochlear Nerve Diseases
|
D020432 |
[Diseases of the fourth cranial (trochlear) nerve or its nucleus in the midbrain. The nerve crosses as it exits the midbrain dorsally and may be injured along its course through the intracranial space, cavernous sinus, superior orbital fissure, or orbit. Clinical manifestations include weakness of the superior oblique muscle which causes vertical DIPLOPIA that is maximal when the affected eye is adducted and directed inferiorly. Head tilt may be seen as a compensatory mechanism for diplopia and rotation of the visual axis. Common etiologies include CRANIOCEREBRAL TRAUMA and INFRATENTORIAL NEOPLASMS.

Troglitazone
|
D000077288 |
[A chroman and thiazolidinedione derivative that acts as a PEROXISOME PROLIFERATOR-ACTIVATED RECEPTORS (PPAR) agonist. It was formerly used in the treatment of TYPE 2 DIABETES MELLITUS, but has been withdrawn due to hepatotoxicity.

Troglotrematidae
|
D014322 |
[A family of flukes (TREMATODA) usually under 10 mm in length, some being only 1 or 2 mm long. In general they are thick, spinous, or scaly flukes having an oval outline and living in various organs and sinuses of birds and mammals. The genus with the greatest interest is PARAGONIMUS.

Trombiculiasis
|
D014323 |
[Infestation with mites of the genus Trombicula, whose larvae carry the rickettsial agent of scrub typhus.

|
Trombiculidae
|
D014324 |
[Family of MITES in the superfamily Trombiculoidea, suborder Prostigmata, which attack humans and other vertebrates, causing DERMATITIS and severe allergic reactions. Chiggers, red bugs, and harvest mites commonly refer to the larval stage of Trombiculid mites, the only parasitic stage of the mite's life cycle.
, A genus of MITES in the family TROMBICULIDAE, whose larvae cause and carry disease. The larvae attack humans and other vertebrates, causing dermatitis and severe allergic reactions. Adult forms do not bite. Species of the subgenera Leptotrombidium are the carriers of SCRUB TYPHUS.
, Subgenus of MITES, in the genus Trombicula, which is the vector for ORIENTIA TSUTSUGAMUSHI, the agent of SCRUB TYPHUS. Some authorities consider Leptotrombidium a genus.

Tromethamine
|
D014325 |
[An organic amine proton acceptor. It is used in the synthesis of surface-active agents and pharmaceuticals; as an emulsifying agent for cosmetic creams and lotions, mineral oil and paraffin wax emulsions, as a biological buffer, and used as an alkalizer. (From Merck, 11th ed; Martindale, The Extra Pharmacopoeia, 30th ed, p1424)

Tropaeolaceae

|
Tropaeolum
|
D032388 |
[A plant genus of the family TROPAEOLACEAE. The common nasturtium is a plant that grows 2.4-3.6 m (8-12 feet) tall and has funnel-shaped flowers that are commonly yellow-orange with red spots or stripes and have a long spur that contains sweet nectar. Some species in this genus are called watercress which is also a common name for RORIPPA and NASTURTIUM.

Trophoblastic Neoplasms
|
D014328 |
[Trophoblastic growth, which may be gestational or nongestational in origin. Trophoblastic neoplasia resulting from pregnancy is often described as gestational trophoblastic disease to distinguish it from germ cell tumors which frequently show trophoblastic elements, and from the trophoblastic differentiation which sometimes occurs in a wide variety of epithelial cancers. Gestational trophoblastic growth has several forms, including HYDATIDIFORM MOLE and CHORIOCARCINOMA. (From Holland et al., Cancer Medicine, 3d ed, p1691)

Trophoblastic Tumor, Placental Site
|
D018245 |
[An uncommon variant of CHORIOCARCINOMA. It is composed almost entirely of mononuclear cytotrophoblasts (TROPHOBLASTS). Because its secretion of hCG (CHORIONIC GONADOTROPIN) is low, a large tumor may develop before the hCG can be detected.

|
Trophoblasts
|
D014327 |
[Trophoblasts with multinuclear cytoplasm and undefined cellular structures. Syncytiotrophoblasts secrete proteolytic enzymes that erode the ENDOMETRIUM for EMBRYO IMPLANTATION. They also produce steroid, peptide, and protein hormones (PLACENTAL HORMONES).
, Cells lining the outside of the BLASTOCYST. After binding to the ENDOMETRIUM, trophoblasts develop into two distinct layers, an inner layer of mononuclear cytotrophoblasts and an outer layer of continuous multinuclear cytoplasm, the syncytiotrophoblasts, which form the early fetal-maternal interface (PLACENTA).
, Trophoblasts with single nucleus and defined cellular structures. As the PLACENTA develops, pockets of cytotrophoblasts serve as stem cells for syncytiotrophoblasts.
