Xenophobia
|
D065806 |
[Intense or irrational dislike or fear of anything that is strange or foreign, particularly of people who are strangers or foreigners. It is an attitudinal orientation of hostility against non-natives in a given population that includes attitudes, prejudices and behavior that reject, exclude or vilify persons, based on the perception that they are outsiders or foreigners to the community, society or national identity.

Xenopus Proteins
|
D029867 |
[Proteins obtained from various species of Xenopus. Included here are proteins from the African clawed frog (XENOPUS LAEVIS). Many of these proteins have been the subject of scientific investigations in the area of MORPHOGENESIS and development.

|
Xenopus laevis
|
D014982 |
[The commonest and widest ranging species of the clawed "frog" (Xenopus) in Africa. This species is used extensively in research. There is now a significant population in California derived from escaped laboratory animals.

Xenorhabdus
|
D020593 |
[A genus of gram-negative, facultatively anaerobic rod-shaped cells which are motile by peritrichous flagella. Late in the growth cycle, spheroplasts or coccoid bodies occur, resulting from disintegration of the cell wall. The natural habitat is the intestinal lumen of certain nematodes.

Xenotropic murine leukemia virus-related virus
|
D058008 |
[An endogenous GAMMARETROVIRUS from the germ line of mice but isolated from humans. It has close similarity to xenotropic MURINE LEUKEMIA VIRUS.

|
Xeroderma Pigmentosum
|
D014983 |
[A rare, pigmentary, and atrophic autosomal recessive disease. It is manifested as an extreme photosensitivity to ULTRAVIOLET RAYS as the result of a deficiency in the enzyme that permits excisional repair of ultraviolet-damaged DNA.

|
Xeroderma Pigmentosum Group A Protein
|
D051760 |
[A ZINC FINGER MOTIF protein that recognizes and interacts with damaged DNA. It is a DNA-binding protein that plays an essential role in NUCLEOTIDE EXCISION REPAIR. Mutations in this protein are associated with the most severe form of XERODERMA PIGMENTOSUM.
] |
|
Xeroderma Pigmentosum Group D Protein
|
D051759 |
[A DNA helicase that is a component of TRANSCRIPTION FACTOR TFIIH. It plays an essential role in NUCLEOTIDE EXCISION REPAIR, and mutations in this protein are associated with XERODERMA PIGMENTOSUM.

|
Xerophthalmia
|
D014985 |
[Dryness of the eye surfaces caused by deficiency of tears or conjunctival secretions. It may be associated with vitamin A deficiency, trauma, or any condition in which the eyelids do not close completely.

|
Xeroradiography
|
D014986 |
[A photoelectric method of recording an X-ray image on a coated metal plate, using low-energy photon beams, long exposure time and dry chemical developers.

Xestospongia
|
D047131 |
[A genus of SPONGES in the family Petrosiidae, characterized by an ectosomal skeleton consisting only of an isotropic reticulation of single spicules or spicule tracts.

|
Xipamide
|
D014988 |
[A sulfamoylbenzamide analog of CLOPAMIDE. It is diuretic and saluretic with antihypertensive activity. It is bound to PLASMA PROTEINS, thus has a delayed onset and prolonged action.
