Sphincter of Oddi
|
D009803 |
[The sphincter of the hepatopancreatic ampulla within the duodenal papilla. The COMMON BILE DUCT and main pancreatic duct pass through this sphincter.
] |
|
Sphincter of Oddi Dysfunction
|
D046628 |
[Organic or functional motility disorder involving the SPHINCTER OF ODDI and associated with biliary COLIC. Pathological changes are most often seen in the COMMON BILE DUCT sphincter, and less commonly the PANCREATIC DUCT sphincter.

|
Sphincterotomy
|
D000074432 |
[Surgical incision of a sphincter.

|
Sphincterotomy, Endoscopic
|
D016717 |
[Incision of SPHINCTER OF ODDI or VATER'S AMPULLA performed by inserting a sphincterotome through DUODENOSCOPE often following or performed during ERCP (ENDOSCOPIC RETROGRADE CHOLANGIOPANCREATOGRAPHY).
] |
|
Sphincterotomy, Transduodenal
|
D013105 |
[Surgical incision of the SPHINCTER OF ODDI in the management of COMMON BILE DUCT DISEASES (e.g., CHOLEDOCHOLITHIASIS; and SPHINCTER OF ODDI DYSFUNCTION).

|
Sphingobacterium
|
D045249 |
[A genus of gram-negative, chemoorganotrophic bacteria in the family Sphingobacteriaceae. They lack FLAGELLA but some species exhibit sliding motility.
] |
|
Sphingolipid Activator Proteins
|
D049128 |
[A family of glycoprotein cofactors that are required for the efficient catabolization of SPHINGOLIPIDS by specific acid hydrolases such as GLUCOSYLCERAMIDASE; GALACTOCEREBROSIDASE; BETA-N-ACETYLHEXOSAMINIDASE; and CEREBROSIDE-SULFATASE.

|
Sphingolipidoses
|
D013106 |
[A group of inherited metabolic disorders characterized by the intralysosomal accumulation of SPHINGOLIPIDS primarily in the CENTRAL NERVOUS SYSTEM and to a variable degree in the visceral organs. They are classified by the enzyme defect in the degradation pathway and the substrate accumulation (or storage). Clinical features vary in subtypes but neurodegeneration is a common sign.

|
Sphingolipids
|
D013107 |
[A class of membrane lipids that have a polar head and two nonpolar tails. They are composed of one molecule of the long-chain amino alcohol sphingosine (4-sphingenine) or one of its derivatives, one molecule of a long-chain acid, a polar head alcohol and sometimes phosphoric acid in diester linkage at the polar head group. (Lehninger et al, Principles of Biochemistry, 2nd ed)

|
Sphingomonadaceae
|
D042301 |
[A family of gram-negative, asporogenous rods or ovoid cells, aerobic or facultative anaerobic chemoorganotrophs. They are commonly isolated from SOIL, activated sludge, or marine environments.
] |
|
Sphingomonas
|
D020578 |
[A genus of gram-negative, aerobic, rod-shaped bacteria characterized by an outer membrane that contains glycosphingolipids but lacks lipopolysaccharide. They have the ability to degrade a broad range of substituted aromatic compounds.
] |
|
Sphingomyelin Phosphodiesterase
|
D013108 |
[An enzyme that catalyzes the hydrolysis of sphingomyelin to ceramide (N-acylsphingosine) plus choline phosphate. A defect in this enzyme leads to NIEMANN-PICK DISEASE. EC 3.1.4.12.
] |
|
Sphingomyelins
|
D013109 |
[A class of sphingolipids found largely in the brain and other nervous tissue. They contain phosphocholine or phosphoethanolamine as their polar head group so therefore are the only sphingolipids classified as PHOSPHOLIPIDS.
] |
|
Sphingosine
|
D013110 |
[An amino alcohol with a long unsaturated hydrocarbon chain. Sphingosine and its derivative sphinganine are the major bases of the sphingolipids in mammals. (Dorland, 28th ed)
] |
|
Sphingosine 1 Phosphate Receptor Modulators
|
D000081243 |
[Agents that affect the function of G-protein coupled SPHINGOSINE 1-PHOSPHATE RECEPTORS. Their binding to the receptors blocks lymphocyte migration and are often used as IMMUNOSUPPRESSANTS.
] |
|
Sphingosine N-Acyltransferase
|
D051049 |
[An enzyme that catalyzes the acyltransferase of SPHINGOSINE to N-acylsphingosine using acyl-COENZYME A as donor and COENZYME A as acceptor. The enzyme is mainly localized in the MITOCHONDRIA.
] |
|
Sphingosine Phosphorylcholine Receptors
|
D000081022 |
[A subfamily of lysophospholipid receptors with specificity for lysophosphatidic acid.
] |
|
Sphingosine-1-Phosphate Receptors
|
D000081025 |
[A subfamily of lysophospholipid receptors with specificity for sphingosine-1-phosphate (e.g., FINGOLIMOD), sphinganine 1-phosphate, 4-hydroxysphinganine 1-phosphate.
] |
|
Sphygmomanometers

|
Spices
|
D017365 |
[The dried seeds, bark, root, stems, buds, leaves, or fruit of aromatic plants used to season food.
