Bardet-Biedl Syndrome
|
D020788 |
[An autosomal recessive disorder characterized by RETINITIS PIGMENTOSA; POLYDACTYLY; OBESITY; MENTAL RETARDATION; hypogenitalism; renal dysplasia; and short stature. This syndrome has been distinguished as a separate entity from LAURENCE-MOON SYNDROME. (From J Med Genet 1997 Feb;34(2):92-8)

Barium
|
D001464 |

Barium Enema
|
D000071941 |
[X-RAY examination of LOWER GASTROINTESTINAL TRACT. Imaging is done while a BARIUM COMPOUND (e.g., BARIUM SULFATE) fills the large intestine via the rectum as a CONTRAST MATERIAL.

Barium Radioisotopes
|
D001465 |
[Unstable isotopes of barium that decay or disintegrate emitting radiation. Ba atoms with atomic weights 126-129, 131, 133, and 139-143 are radioactive barium isotopes.

Barium Sulfate
|
D001466 |
[A compound used as an x-ray contrast medium that occurs in nature as the mineral barite. It is also used in various manufacturing applications and mixed into heavy concrete to serve as a radiation shield.

|
Baroreflex
|
D017704 |
[A response by the BARORECEPTORS to increased BLOOD PRESSURE. Increased pressure stretches BLOOD VESSELS which activates the baroreceptors in the vessel walls. The net response of the CENTRAL NERVOUS SYSTEM is a reduction of central sympathetic outflow. This reduces blood pressure both by decreasing peripheral VASCULAR RESISTANCE and by lowering CARDIAC OUTPUT. Because the baroreceptors are tonically active, the baroreflex can compensate rapidly for both increases and decreases in blood pressure.

Barotrauma
|
D001469 |
[Injury following pressure changes; includes injury to the eustachian tube, ear drum, lung and stomach.

|
Barrett Esophagus
|
D001471 |
[A condition with damage to the lining of the lower ESOPHAGUS resulting from chronic acid reflux (ESOPHAGITIS, REFLUX). Through the process of metaplasia, the squamous cells are replaced by a columnar epithelium with cells resembling those of the INTESTINE or the salmon-pink mucosa of the STOMACH. Barrett's columnar epithelium is a marker for severe reflux and precursor to ADENOCARCINOMA of the esophagus.

Barrington's Nucleus
|
D065835 |
[A nucleus in the pons with exon projections to the sacral parasympathetic nucleus associated with bladder control.

Barringtonia
|
D031382 |
[A plant genus of the family Lecythidaceae. Members contain nasimalun A and B (neo-clerodane diterpenoids).

Barth Syndrome
|
D056889 |
[Rare congenital X-linked disorder of lipid metabolism. Barth syndrome is transmitted in an X-linked recessive pattern. The syndrome is characterized by muscular weakness, growth retardation, DILATED CARDIOMYOPATHY, variable NEUTROPENIA, 3-methylglutaconic aciduria (type II) and decreases in mitochondrial CARDIOLIPIN level. Other biochemical and morphological mitochondrial abnormalities also exist.

Bartholin's Glands
|
D001472 |
[Mucus-secreting glands situated on the posterior and lateral aspect of the vestibule of the vagina.

|
Bartonella
|
D001473 |
[A genus of gram-negative bacteria characteristically appearing in chains of several segmenting organisms. It occurs in man and arthropod vectors and is found only in the Andes region of South America. This genus is the etiologic agent of human bartonellosis. The genus Rochalimaea, once considered a separate genus, has recently been combined with the genus Bartonella as a result of high levels of relatedness in 16S rRNA sequence data and DNA hybridization data.

|
Bartonella Infections
|
D001474 |
[Infections by the genus BARTONELLA. Bartonella bacilliformis can cause acute febrile anemia, designated Oroya fever, and a benign skin eruption, called verruga peruana. BARTONELLA QUINTANA causes TRENCH FEVER, while BARTONELLA HENSELAE is the etiologic agent of bacillary angiomatosis (ANGIOMATOSIS, BACILLARY) and is also one of the causes of CAT-SCRATCH DISEASE.

Bartonella bacilliformis
|
D045503 |
[The type species of the genus BARTONELLA, a gram-negative bacteria found in humans. It is found in the mountain valleys of Peru, Ecuador, and Southwest Columbia where the sandfly (see PHLEBOTOMUS) vector is present. It causes OROYA FEVER and VERRUGA PERUANA.

|
Bartonella henselae
|
D018416 |
[A species of gram-negative bacteria that is the etiologic agent of bacillary angiomatosis (ANGIOMATOSIS, BACILLARY). This organism can also be a cause of CAT-SCRATCH DISEASE in immunocompetent patients.
