Integral: Exp[-(x-m)^2/(2 s^2)] x^3 (1+x^2)^-1

Hi,
    any suggestion to make the integral of:

Exp[-(x-m)^2/(2 s^2)] x (1+x^2)^-1
Exp[-(x-m)^2/(2 s^2)] x^2 (1+x^2)^-1

Exp[-(x-m)^2/(2 s^2)] x^3 (1+x^2)^-1



between -inf and +inf (or indefinite)?

Look like it is not possible, but it is too long time I do not make
integrals with more advanced techinques (as going to the complex plane)...
so if you have suggestions (wonderful a solution :) )....

THANKS

Ale
