Abstract:
Nucleic acid molecules that encode R2 subunit protein and topoisomerase I protein, fragments thereof, recombinant expression vectors and host cells are disclosed. Oligonucleotide molecules with nucleotide sequences complimentary to a nucleotide sequence encode R2 subunit protein and topoisomerase I protein are disclosed.
Abstract:
A bicycle pedal assembly having a pedal body rotatably coupled to a pedal shaft. A bore receiving the pedal shaft passes through the pedal body. A semi-cylindrical shoulder extends outwardly from an exterior surface of the shaft. A bushing is positioned within the bore to rotatably support the pedal shaft. An inner surface of the shoulder rotatably engages the external end of the bushing, so that the second end of the shaft is movably connected to the pedal body without assistance of any fasteners.

Abstract:
The invention is a chain unit comprising first and second link units, a unitary outer plate, and first and second pins. Each link unit comprises two inner plates with two rollers positioned therebetween. The outer plate straddles and is secured to the link units. Outer plate comprises two walls and a bridge positioned therebetween that spans the tooth engaging space between link units. The unitary construction of the outer plate provides a structural integrity that prevents the plates from separating when the chain is exposed to force. A plurality of chain units can be linked together to form a chain.
