  Semiconducting-like low-temperature in-plane resistivity indicates that there
are no remnants of superconductivity above the resistive phase transition at T
> Tc in underdoped cuprates. The model with the chemical potential pinned near
the mobility edge inside the charge-transfer optical gap describes
quantitatively the Nernst effect, thermopower, diamagnetism and the unusual
low-temperature resistivity of underdoped cuprates as normal state phenomena
above Tc.
