Levocardia
|
D007979 |
[Congenital abnormalities in which the HEART is in the normal position (levocardia) in the left side of the chest but some or all of the THORAX or ABDOMEN viscera are transposed laterally (SITUS INVERSUS). It is also known as situs inversus with levocardia, or isolated levocardia. This condition is often associated with severe heart defects and splenic abnormalities such as asplenia or polysplenia.

Levodopa
|
D007980 |
[The naturally occurring form of DIHYDROXYPHENYLALANINE and the immediate precursor of DOPAMINE. Unlike dopamine itself, it can be taken orally and crosses the blood-brain barrier. It is rapidly taken up by dopaminergic neurons and converted to DOPAMINE. It is used for the treatment of PARKINSONIAN DISORDERS and is usually given with agents that inhibit its conversion to dopamine outside of the central nervous system.

Lewis Blood Group Antigens
|
D007983 |
[Carbohydrate antigens structurally related to the Lewis blood group system antigens. They include substrates for the Le gene product, Le(c) and Le(d); ISOANTIGENS of the Lewis antigens; sialated versions of the Lewis antigens and their isoantigens; and other derivatives of the Le antigens and their isoantigens. They are indicated as so with the word Lewis or the letters Le in the name or abbreviation of the antigen.
, Carbohydrate antigens structurally related to the ABH BLOOD-GROUP SYSTEM. They may occur as a modification of saccharide chains on glycolipids or glycoproteins on cell surfaces or in plasma, or as free oligosaccharides in secretions. Lewis antigens are not synthesized in blood cells. Instead Lewis glycolipids present in plasma are absorbed onto the surface of ERYTHROCYTES; LYMPHOCYTES; and PLATELETS. The phenotypes Le(a) and Le(b) are the result of the actions of two genes the Le gene (fucosyltransferase FUT3) and the Se gene (fucosyltransferase FUT2) on the precursor carbohydrate, glycolipid or glycoprotein. Other FUCOSYLTRANSFERASES can also synthesize the Lewis antigens.

Lewis X Antigen
|
D016256 |
[A trisaccharide antigen expressed on glycolipids and many cell-surface glycoproteins. In the blood the antigen is found on the surface of NEUTROPHILS; EOSINOPHILS; and MONOCYTES. In addition, Lewis X antigen is a stage-specific embryonic antigen.

|
Lewy Bodies
|
D016631 |
[Intracytoplasmic, eosinophilic, round to elongated inclusions found in vacuoles of injured or fragmented neurons. The presence of Lewy bodies is the histological marker of the degenerative changes in LEWY BODY DISEASE and PARKINSON DISEASE but they may be seen in other neurological conditions. They are typically found in the substantia nigra and locus coeruleus but they are also seen in the basal forebrain, hypothalamic nuclei, and neocortex.
