The matching at one-loop order of all the relevant renormalization constants with the continuum \\bar{MS} scheme is presented. Our calculations include: 1) the contributions arising from the Clover term of the action; 2) the complete mixing of the gluon operator G \\tilde{G} with the divergence of the singlet axial current; 3) the use of both local and extended definitions of the fermionic bilinear operators.
