This invention relates to a tread rubber composition for tires with the addition of crosslinked resinous nanoparticles having a high glass transition temperature (Tg) into elastomeric base polymers. The invention demonstrates greatly improved handling performance without deteriorating controllability and stability during high-speed running. The present invention more specifically discloses a tire which is comprised of a generally toroidal-shaped carcass with an outer circumferential tread, two spaced beads, at least one ply extending from bead to bead and sidewalls extending radially from and connecting said tread to said beads; wherein said tread is adapted to be ground-contacting; and wherein the tread is comprised of a rubber composition comprising: (1) a rubbery polymer; (2) from 1 to 30 parts per hundred parts of rubber by weight of pre-crosslinked polymer particles, wherein the pre-crosslinked polymer particles have a mean number average particle size as determined by light scattering which is within the range of 30 nm to 500 nm, wherein the pre-crosslinked polymer is comprised of repeat units that are derived from at least one monomer selected from the group consisting of acrylate monomers, acrylonitrile monomer, and vinyl halide monomers, wherein the pre-croslinked polymer is in the form of core-shell particles having a core and a shell, and wherein the pre-crosslinked polymer has a glass transition temperature which is within the range of 30° C. to 200° C.; and (3) 10 to 150 parts per hundred parts of rubber by weight of at least one filler selected from the group consisting of carbon black and silica.

The present invention provides conjugates between erythropoietin and PEG moieties. The conjugates are linked via an intact glycosyl linking group interposed between and covalently attached to the peptide and the modifying group. The conjugates are formed from glycosylated peptides by the action of a glycosyltransferase. The glycosyltransferase ligates a modified sugar moiety onto a glycosyl residue on the peptide. Also provided are methods for preparing the conjugates, methods for treating various disease conditions with the conjugates, and pharmaceutical formulations including the conjugates.

The invention relates to a packing container for roll articles, which can reliably fix and store roll articles during the carrying process. Meanwhile, the roll articles are simple to store and take out. The packing container (1) comprises a container body consisting of a bracket (2) and sidewalls (3) and used for storing roll articles (50) wound on a winding core; a pair of bearing members (4) with notches for holding the winding core wound with the roll articles and used for holding the roll articles in a suspended manner; a pair of pressing members (5) arranged along the upper parts of the bearing members (4); a pair of fixed columnar lower spacers arranged along the sidewall of the container body; a pair of columnar upper spacers arranged corresponding to the lower spacers; and a cover body (6) of the container body.
