  In the present paper, which is a sequel to arXiv:1001:4018, we compute the
one-loop correction to the energy of pulsating string solutions in AdS_5 x S^5.
We show that, as for rigid spinning string elliptic solutions, the fluctuation
operators for pulsating solutions can be also put into the single-gap Lame'
form. A novel aspect of pulsating solutions is that the one-loop correction to
their energy is expressed in terms of the stability angles of the quadratic
fluctuation operators. We explicitly study the "short string" limit of the
corresponding one-loop energies, demonstrating a certain universality of the
form of the energy of "small" semiclassical strings. Our results may help to
shed light on the structure of strong-coupling expansion of anomalous
dimensions of dual gauge theory operators.
