Record 1 2013-12-04

English

Subject field(s)
  • Space Weapons
DEF

A satellite that weighs 100 kilograms or less.

CONT

These micro/nanosatellites, when employed as unacknowledged secondary payloads, can covertly rendezvous with other space assets to perform satellite inspection and other missions to disrupt, degrade, or destroy space assets.

Key term(s)
  • micro-satellite

French

Domaine(s)
  • Armes orbitales
DEF

Satellite pesant 100 kilogrammes ou moins.

OBS

Ce genre de satellite pourrait être embarqué comme charge payante secondaire à bord d'un véhicule spatial pour se rapprocher subrepticement de systèmes déployés dans l'espace en vue de les endommager ou de les détruire.

Key term(s)
  • micro-satellite

Spanish

Campo(s) temático(s)
  • Armas espaciales

Record 2 2013-07-17

English

Subject field(s)
  • Genetics
CONT

To determine the frequency of short tandem repeat instability in adenocarcinoma of the prostate, we studied 40 tumors that were stratified according to tumor grade. The tissue samples were screened with di-, tri- and tetranucleotide markers spanning a wide range of chromosomal loci, including an androgen receptor gene trinucleotide repeat. Microsatellite instability was observed overall in only one of the 40 (2.5%) prostate adenocarcinomas studied. This replication error-positive tumor demonstrated repeat length alterations at two loci.

French

Domaine(s)
  • Génétique
CONT

L'avènement de la méthode d'amplification par PCR [réaction en chaîne de la polymérase] a permis d'accéder en 1989 à une deuxième catégorie de polymorphisme de répétition, où le motif de base répété en tandem est plus court (1 à 5 nucléotides) : ce sont des microsatellites ou STR [séquences répétées en tandem].

Spanish

Campo(s) temático(s)
  • Genética
DEF

Segmento de ADN que se caracteriza por contener un número variable de copias, generalmente entre 5 y 50, de una secuencia de 5 o menos bases llamada unidad de repetición.

CONT

La existencia de alelos múltiples (alto nivel de polimorfismo) permite que los microsatélites se empleen como potentes marcadores en muchas especies diferentes. Se detectan por la reacción en cadena de la polimerasa.

CONT

Microsatélites. Semejantes a los minisatélites, pero con un tamaño alélico menor, en el rango de dos a cuatro nucleótidos. En el genoma humano existen varias decenas de miles, presentándose aproximadamente uno por cada 100.000 p.b [pares de bases].

Record 3 2004-08-03

English

Subject field(s)
  • Spacecraft

French

Domaine(s)
  • Engins spatiaux
DEF

Satellite caractérisé par une masse de quelques dizaines de kilogrammes.

OBS

Les microsatellites sont souvent des réalisations d'associations scientifiques ou de laboratoires de recherche.
