  We present spectra of charged pions and protons in 0-10% central Au+Au
collisions at $\sqrt{s_{NN}}=200$ GeV at mid-rapidity ($y=0$) and forward
pseudorapidity ($\eta=2.2$) measured with the BRAHMS experiment at RHIC. The
spectra are compared to spectra from p+p collisions at the same energy scaled
by the number of binary collisions. The resulting nuclear modification factors
for central Au+Au collisions at both $y=0$ and $\eta=2.2$ exhibit suppression
for charged pions but not for (anti-)protons at intermediate $p_T$. The
$\bar{p}/\pi^-$ ratios have been measured up to $p_T\sim 3$ GeV/$c$ at the two
rapidities and the results indicate that a significant fraction of the charged
hadrons produced at intermediate $p_T$ range are (anti-)protons at both
mid-rapidity and $\eta = 2.2$.
