  This paper is a natural continuation of [8], where strong Markov processes
are constructed in time inhomogeneous setting with Borel measurable uniformly
bounded and uniformly nondegenerate diffusion and drift in
$L_{d+1}(\mathbb{R}^{d+1})$. Here we study some properties of these processes
such as higher summability of Green's functions, boundedness of resolvent
operators in Lebesgue spaces, establish It\^o's formula, and so on.
