                                    Resum

  We analyze the screening effects on the nucleon-nucleon cross-section, as
due to the modifications introduced by the nuclear medium on the propagation
   of the mesons which mediate the interaction. We work in a relativistic
   lagrangian model with sigma, omega and pi meson exchange and take into
 account renormalized vacuum contributions and sigma-omega mixing. The total
   and differential elastic proton-proton cross section are calculated at
 finite density, temperature and background fluid velocity. The results are
           compared with experimental constraints when available.
