Provided is an elastomer reinforcement cord with improved rust resistance. An elastomer reinforcement cordincludes metal filaments and a polymer material. The elastomer reinforcement cordhas a multi-strand structure which includes: at least one core strandformed by twisting plural metal filamentsandtogether; and two or more sheath strandseach formed by twisting plural metal filamentsandtogether, the sheath strands being twisted together around the core strand. An intra-sheath-strand filling rate a, which is a ratio of the area of the polymer material with respect to an intra-sheath-strand gap region A, is 52% or higher, and an inter-strand filling rate b, which is a ratio of the area of the polymer material with respect to an inter-strand gap region B, is 75% or higher.

Elastomer reinforcement cord

Provided is a steel cord for rubber article reinforcement which has excellent corrosion resistance and productivity without deterioration of adhesion with rubber. A steel cord () for rubber article reinforcement, in which plural steel filaments () are twisted together, includes: a core having at least one core filament (); and a sheath having at least one sheath layer formed by twisting at least one sheath filament () around the core. In this steel cord (), brass plating is performed on the steel filaments () and zinc plating is further performed on the outer circumference of the brass plating of the core filament (), and the steel filaments () have a diameter d of 0.1 mm to 0.6 mm.

Steel cord for reinforcing rubber article

A cord for reinforcing elastomers excellent in adhesion to elastomers such as rubber is provided. The cord is a cord for reinforcing elastomers () that includes metallic filaments () and a resin filament () twisted together, the resin filament () being made from a polymeric material having a melting point or softening point of 80 to 160&#xb0; C. The cord for reinforcing elastomers includes a core and at least one sheath layer, wherein, after vulcanization, a distance w between metallic filaments () forming an outermost sheath layer is 100 &#x3bc;m or less, and, on a cross section of the cord taken along a direction orthogonal to an axial direction, a filling ratio, which is a ratio of an area of a polymeric material () derived from the resin filament () to a gap region is 52 to 120%, where the gap region is defined as a portion occupied by a material other than the metallic filaments () within a region formed by connecting the centers of the individual metallic filaments () constituting the outermost sheath layer.

Cord for reinforcing elastomers

A method to identify target genes or proteins for regulating melanogenesis or pigmentation and to screen for compounds for manipulation of melanogenesis or pigmentation, the method of screening for candidate compounds for regulating melanogenesis or pigmentation, includes bringing test compounds into contact with cells capable of expressing mortalin and/or Hsp60 in vitro, and selecting, from among the test compounds, a compound that changes the expression level of mortalin and/or Hsp60.
