Record 2 2017-03-30

English

Subject field(s)
  • Biochemistry
  • Molecular Biology
DEF

A protein found abundantly in the nucleoli of cells, associated with the transcription of ribosomal RNA [ribonucleic acid] and the assembly of ribosomes.

French

Domaine(s)
  • Biochimie
  • Biologie moléculaire
DEF

Phosphoprotéine du nucléole, qui intervient dans la maturation des pré-ARN [acides ribonucléiques] ribosomaux et dans l'assemblage des sous-unités des ribosomes.

Record 3 2014-04-14

English

Subject field(s)
  • Genetics
  • Cytology
DEF

A small spherical body within a living cell that is the site of protein synthesis. They consist of a type of RNA (called ribosomal RNA) and protein. During protein synthesis they are associated with messenger RNA in the process of translation.

French

Domaine(s)
  • Génétique
  • Cytologie
DEF

Organite cellulaire assemblé dans le noyau de la cellule, au niveau du nucléole par assemblage de protéines et d’ARN ribosomique. Ils interviennent dans la synthèse protéique en rapprochant à la fois l'ARN messager en traduction, les ARN de transfert portant les acides aminés et la chaîne protéique en élongation.

Spanish

Campo(s) temático(s)
  • Genética
  • Citología
DEF

Organelo citoplasmático, compuesto de ARN y proteína, que forma parte del mecanismo sintetizador de proteínas de la célula.

OBS

El ribosoma interactúa con el ARN mensajero para ensamblar unidades de aminoácidos en una cadena de polipéptidos de acuerdo a la secuencia determinada por el código genético.

Record 4 2003-07-25

English

Subject field(s)
  • Non-Surgical Treatment
  • Epidermis and Dermis
DEF

A treatment involving exposing patients to ultraviolet radiation after they have taken methoxsalen (8-MOP).

CONT

Recently there has been a rapid development in the world-wide use of oral and topical methoxsalen (8-methoxypsoralen; 8-MOP) with long wave ultraviolet light (UVA) for treating patients with psoriasis. This form of photochemotherapy is known as PUVA treatment, and is effective in clearing and maintaining a remission of psoriasis in most patients treated.

OBS

The light activates the drug, which then binds to DNA and causes cell death. Since the effects are confines to the skin, this is a treatment for mycosis fungoides as well as other skin disorders. A possible side effect of this treatment is the development of secondary skin cancers.

French

Domaine(s)
  • Traitements non chirurgicaux
  • Épiderme et derme
CONT

Il semble que la PUVA thérapie provoque une inhibition de la kératinisation anormale, probablement due à un gène de réflexion et que ce phénomène puisse être relié à des modifications des centres fibrillaires du nucléole du kératinocyte psoriasique.

OBS

«puvathérapie» : Relevé dans Biofutur, numéro 114, juillet-août 1992, page 35.

Spanish

Campo(s) temático(s)
  • Tratamiento sin cirugía
  • Epidermis y dermis
DEF

Tratamiento que consiste en la exposición del paciente a radiación ultravioleta, una vez que haya ingerido [o aplicado en la piel] methoxsalen (8-MOP).

OBS

La luz ultravioleta activa el fármaco, que a continuación, se liga al ADN, produciendo la muerte celular en el área afectada. Puesto que sólo se afecta la piel, esto es un tratamiento para la micosis fungoide, así como para otras alteraciones de la piel. Un posible efecto secundario de este tratamiento es el desarrollo de cánceres de la piel secundarios.

Record 5 2003-04-11

English

Subject field(s)

DEF

A small mass of intensely staining chromatin seen in the nucleus of the female cell during interphase. Variably shaped, it is adjacent to the inner surface of the nuclear membrane.

French

Domaine(s)
  • Génétique
DEF

Grain de chromatine accolé au nucléole ou à la face interne de la membrane nucléaire. Il correspond à un chromosome X inactivé pendant l'interphase cellulaire et existe dans les cellules des sujets normaux de sexe féminin.
