Bartter Syndrome
|
D001477 |
[A group of disorders caused by defective salt reabsorption in the ascending LOOP OF HENLE. It is characterized by severe salt-wasting, HYPOKALEMIA; HYPERCALCIURIA; metabolic ALKALOSIS, and hyper-reninemic HYPERALDOSTERONISM without HYPERTENSION. There are several subtypes including ones due to mutations in the renal specific SODIUM-POTASSIUM-CHLORIDE SYMPORTERS.

D064652 |
[Structures which form the base of FLAGELLA and CILIA. They contain nine triplets of MICROTUBULES that are arranged around the periphery and that serve as the nucleation center for AXONEME assembly.
, The basal bodies of CILIA.

Basal Cell Nevus Syndrome
|
D001478 |
[Hereditary disorder consisting of multiple basal cell carcinomas, odontogenic keratocysts, and multiple skeletal defects, e.g., frontal and temporoparietal bossing, bifurcated and splayed ribs, kyphoscoliosis, fusion of vertebrae, and cervicothoracic spina bifida. Genetic transmission is autosomal dominant.

Basal Forebrain
|
D066187 |
[The region of the telencephalon located rostral and ventral to the STRIATUM comprising AMYGDALA; SEPTAL NUCLEI; SUBSTANTIA INNOMINATA and ventral pallidum.

Basal Ganglia
|
D001479 |
[Large subcortical nuclear masses derived from the telencephalon and located in the basal regions of the cerebral hemispheres.

|
Basal Ganglia Cerebrovascular Disease
|
D020144 |
[A pathological condition caused by impaired blood flow in the basal regions of cerebral hemispheres (BASAL GANGLIA), such as INFARCTION; HEMORRHAGE; or ISCHEMIA in vessels of this brain region including the lateral lenticulostriate arteries. Primary clinical manifestations include involuntary movements (DYSKINESIAS) and muscle weakness (HEMIPARESIS).

|
Basal Ganglia Diseases
|
D001480 |
[Diseases of the BASAL GANGLIA including the PUTAMEN; GLOBUS PALLIDUS; claustrum; AMYGDALA; and CAUDATE NUCLEUS. DYSKINESIAS (most notably involuntary movements and alterations of the rate of movement) represent the primary clinical manifestations of these disorders. Common etiologies include CEREBROVASCULAR DISORDERS; NEURODEGENERATIVE DISEASES; and CRANIOCEREBRAL TRAUMA.

|
Basal Ganglia Hemorrhage
|
D020145 |
[A collection of blood in BASAL GANGLIA.
, Bleeding within the subcortical regions of cerebral hemispheres (BASAL GANGLIA). It is often associated with HYPERTENSION or ARTERIOVENOUS MALFORMATIONS. Clinical manifestations may include HEADACHE; DYSKINESIAS; and HEMIPARESIS.

|
Basal Metabolism
|
D001481 |
[Metabolism (e.g., heat production) of an organism in an inactive, awake, fasting state. It may be determined directly by means of a calorimeter or indirectly by calculating the end products of oxidation within the organism or from the amount of oxygen utilized.

|
Basal Nucleus of Meynert
|
D020532 |
[A group of nerve cells in the SUBSTANTIA INNOMINATA that has wide projections to the NEOCORTEX and is rich in ACETYLCHOLINE and CHOLINE ACETYLTRANSFERASE. In PARKINSON DISEASE and ALZHEIMER DISEASE the nucleus undergoes degeneration.

Base Composition
|
D001482 |
[The relative amounts of the PURINES and PYRIMIDINES in a nucleic acid.
] |
|
Base Pair Mismatch
|
D020137 |
[The presence of an uncomplimentary base in double-stranded DNA caused by spontaneous deamination of cytosine or adenine, mismatching during homologous recombination, or errors in DNA replication. Multiple, sequential base pair mismatches lead to formation of heteroduplex DNA; (NUCLEIC ACID HETERODUPLEXES).
] |
|
Base Pairing
|
D020029 |
[Pairing of purine and pyrimidine bases by HYDROGEN BONDING in double-stranded DNA or RNA.
] |
|
Base Sequence
|
D001483 |
[The sequence of PURINES and PYRIMIDINES in nucleic acids and polynucleotides. It is also called nucleotide sequence.

|
Basement Membrane
|
D001485 |
[A darkly stained mat-like EXTRACELLULAR MATRIX (ECM) that separates cell layers, such as EPITHELIUM from ENDOTHELIUM or a layer of CONNECTIVE TISSUE. The ECM layer that supports an overlying EPITHELIUM or ENDOTHELIUM is called basal lamina. Basement membrane (BM) can be formed by the fusion of either two adjacent basal laminae or a basal lamina with an adjacent reticular lamina of connective tissue. BM, composed mainly of TYPE IV COLLAGEN; glycoprotein LAMININ; and PROTEOGLYCAN, provides barriers as well as channels between interacting cell layers.
