Umbilical Cord
|
D014470 |
[The flexible rope-like structure that connects a developing FETUS to the PLACENTA in mammals. The cord contains blood vessels which carry oxygen and nutrients from the mother to the fetus and waste products away from the fetus.

|
Umbilical Veins
|
D014471 |
[Venous vessels in the umbilical cord. They carry oxygenated, nutrient-rich blood from the mother to the FETUS via the PLACENTA. In humans, there is normally one umbilical vein.

Umbilicus
|
D014472 |
[The pit in the center of the ABDOMINAL WALL marking the point where the UMBILICAL CORD entered in the FETUS.

Umbridae
|
D017877 |
[A family of ESOCIFORMES comprising the mudminnows. There are three genera: Dallia, Novumbra, and Umbra, with much disagreement about their taxonomic interrelations. The Umbridae are freshwater fish inhabiting parts of the Northern Hemisphere.

|
Uncoupling Agents
|
D014475 |
[Chemical agents that uncouple oxidation from phosphorylation in the metabolic cycle so that ATP synthesis does not occur. Included here are those IONOPHORES that disrupt electron transfer by short-circuiting the proton gradient across mitochondrial membranes.
] |
|
Uncoupling Protein 1
|
D000071256 |
[A mitochondrial uncoupling protein that is expressed in BROWN ADIPOSE TISSUE. It is critical for NONSHIVERING THERMOGENESIS to prevent heat loss in NEONATES.
] |
|
Uncoupling Protein 2
|
D000071246 |
[A mitochondrial uncoupling protein that is expressed in many tissues and exhibits the greatest expression in SKELETAL MUSCLE. It regulates mitochondrial ATP production and the generation of REACTIVE OXYGEN SPECIES.
] |
|
Uncoupling Protein 3
|
D000071247 |
[A mitochondrial uncoupling protein that is expressed in heart and skeletal muscle tissues. It functions to regulate tissue respiration, energy balance, and THERMOGENESIS. Mutations in the UCP3 gene are associated with OBESITY.

|
Undaria
|
D044648 |
[A genus of BROWN ALGAE, in the family Alariaceae, native to Japan, Korea, and China. The edible SEAWEED Undaria pinnatifida is also called wakame.

D000080842 |
[Rare and common diseases lacking a diagnosis.
] |
|
Undifferentiated Connective Tissue Diseases
|
D000074079 |
[Diseases that exhibit signs and symptoms suggestive of a connective tissue disease that do not fulfill clinical or diagnostic criteria for any one defined disease but overlap with criteria of multiple such diseases. Commonly overlapping diseases include systemic autoimmune connective tissue diseases such as RHEUMATOID ARTHRITIS; SYSTEMIC LUPUS ERYTHEMATOSUS; and SYSTEMIC SCLEROSIS.
