English

Subject field(s)
  • Space Exploration Equipment and Tools
CONT

Power data grapple fixtures(PDGF), located on the exterior of the International Space Station(ISS), supply power and data to Canadarm2 and Dextre. These fixtures are strategically placed to provide the robots with access to many parts of the Station's outer surface.

OBS

power data grapple fixture; PDGF : designations officially approved by the International Space Station Terminology Approval Group(ISSTAG).

Domaine(s)
  • Équipement et outillage d'exploration spatiale
CONT

Les bornes électromécaniques installées sur la Station spatiale internationale servent au Canadarm2 et à Dextre pour l'alimentation en électricité et la transmission de données. Leurs positions stratégiques permettent aux robots d'avoir accès à de nombreux endroits autour de la Station.

OBS

borne électromécanique; PDGF : désignations uniformisées par le Groupe de travail de la terminologie de la Station spatiale internationale (GTTSSI).

  • Genetics
  • Biochemistry
CONT

Addition of bacterial sphingomyelinase to quiescent Swiss 3T3 cells effectively potentiated the platelet-derived growth factor(PDGF)-stimulated cell proliferation, though the enzyme by itself had little effect on the cell proliferation. Such potentiation of the cell growth could also be observed by the addition of ceramide, a product of the sphingomyelinase-catalysed reaction. In contrast, phosphocholine, another product of the enzyme reaction, had no synergistic effect on the action of PDGF. Treatment of the cells with sphingomyelinase or ceramide increased the cellular activity of mitogen-activated protein kinases(MAP kinases), which have been implicated in the regulation of cell proliferation.

Certaines cytokines, des agents différentiateurs, ou des effecteurs antitumoraux activent une voie de transmission du signal intracellulaire caractérisée par l'hydrolyse de la sphingomyéline et production de céramide sous l'effet de sphingomyélinases.

Subject field(s)
  • Orbital Stations
  • Space Exploration Equipment and Tools
CONT

To provide the increased mass handling capability and mobility of Canadarm2, Latching End Effectors (LEE) have been designed to provide power and data signals at both ends of the arm. (These are the devices that provide the actual electrical and mechanical interface to the Power Data Grapple Fixtures ... Additionally, the increased requirement for mass handling necessitated the use of mechanical latches that will augment the three-wire snare mechanism (first developed for the Shuttle’s Canadarm) as the principal load bearing device. Incorporated into one elegant assembly, this electro-mechanical interface appears four times on each Canadarm2 LEE. The precision alignment of the mating connectors is achieved through the introduction of a matching pair of curvic couplings.

CONT

... the SSRMS [Space Station Remote Manipulator System] has been designed in such a manner that a Latching End Effector is mounted at each end of the arm, thus allowing the arm to "walk", hand over hand, around the entire space station. The range of accessibility of the SSRMS will be limited only the the number of Power Data Grapple Fixtures(PDGF) installed on the station.

OBS

latching end effector; LEE: term and abbreviation officially approved by the International Space Station official approval Group (ISSOAG).

PHR

Latching end effector unit.

CONT

Le nouveau bras [destiné à la Station spatiale internationale] peut se déplacer à l'image d'un ver de terre. Il est équipé à chaque extrémité d'un système de capture appelé «Latching End Effector (LEE)» qui peut venir s'attacher sur une autre structure le «Power Data Grapple Fixtures (PDGF)». En se détachant d'une extrémité, le bras peut ainsi se déplacer le long de la station dans un large rayon en fonction des structures PDGF installées.

OBS

effecteur de verrouillage; LEE : terme et abréviation uniformisés par le Groupe de travail de la terminologie de la Station spatiale internationale (GTTSSI).

PHR

Bloc de l'effecteur de verrouillage.

  • Biochemistry
CONT

Surgical biopsies from 10 head and neck squamous cell carcinomas were labeled in vitro with bromodeoxyuridine. In histological sections, bromodeoxyuridine-positive nuclei and beta-fibroblast growth factor(beta-FGF) were stained using immunohistochemistry. In clearly discernible clusters of tumor cells, the cytoplasm shows strong positive beta-FGF staining, whereas other tumor regions are completely beta-FGF negative... Three classes of mesoderm-inducing factor(MIF) that might be responsible for... interaction in vivo... These are members of the transforming growth factor type beta(TGF-beta), fibroblast growth factor(FGF) and Wnt families... Six well-characterized human growth factors were chosen for detailed investigation by topical application to standardized skin wounds in swine : epidermal growth factor(EGF), transforming growth factors alpha and beta(TGF-alpha and TGF-beta), fibroblast growth factor(FGF), insulin-like growth factor-1(IGF-l), and platelet-derived growth factor(PDGf).
