English

Subject field(s)
  • Pharmacology

Record 2 2014-05-21

English

Subject field(s)
  • Biochemistry
CONT

Actin-related protein complex is an actin assembly complex involved in the movement of cells and mitochondria during cell division and budding of yeast.

CONT

... the ARP complex... nucleates actin filament growth from the minus end, allowing rapid elongation at the plus end. However, the complex can also attach to the side of another actin filament while remaining bound to the minus end of the filament that it has nucleated, thereby building individual filaments into a treelike web... The ARP complex is localized in regions of rapid actin filament growth such as lamellipodia, and its nucleating activity is regulated by intracellular signaling molecules and components at the cytosolic face of the plasma membrane.

French

Domaine(s)
  • Biochimie
CONT

La migration cellulaire dépend de la formation de réseaux d'une protéine fibreuse, l'actine, qui permettent à la cellule de projeter sa membrane en formant une structure appelée lamellipode. Les fibres d'actine qui génèrent cette force sont branchées entre elles grâce à une machine moléculaire appelée «complexe Arp2/3».

Key term(s)
  • complexe Arp 2/3

Record 5 2001-12-17

English

Subject field(s)
  • Metallography
  • Ferrous Alloys
CONT

The chemical composition can alter the nucleating(graphitizing) tendency of cast irons to a certain extent. As the carbon equivalent is lowered the tendency to solidify with a more carbidic microstructure increases. As the level of carbide statilizing elements is increased, the same effect is seen.

French

Domaine(s)
  • Métallographie
  • Alliages ferreux
DEF

Qualifie un élément qui, ajouté à un alliage fer-carbone, empêche la séparation du graphite à la solidification et favorise la formation de carbure.

Subject field(s)
  • Air Pollution
  • Environmental Studies and Analyses
  • Climatology
CONT

There is still another effect of volcanic dust which may be just as important as its direct screening of solar radiation, and that is its ability to serve as nuclei for ice-crystal formation in the atmosphere. Schaefer has studied the nucleating efficiency of volcanic-ash particles in serving as nuclei for the formation of ice crystals.
