  We present new interior regularity criteria for suitable weak solutions of
the 3-D Navier-Stokes equations: a suitable weak solution is regular near an
interior point $z$ if either the scaled $L^{p,q}_{x,t}$-norm of the velocity
with $3/p+2/q\leq 2$, $1\leq q\leq \infty$, or the $L^{p,q}_{x,t}$-norm of the
vorticity with $3/p+2/q\leq 3$, $1 \leq q < \infty$, or the
$L^{p,q}_{x,t}$-norm of the gradient of the vorticity with $3/p+2/q\leq 4$, $1
\leq q$, $1 \leq p$, is sufficiently small near $z$.
