Abstract: Pharmaceutical compositions and methods for using a fusion protein having a superoxide dismutase and a transit peptide are described. Pharmaceutical compositions and methods for using the fusion protein in combination with other antiretroviral agents for treating patients with AIDS or HTV infection are also described.

Abstract: A CT imaging system and a method for determining a CT collimator slit profile. The method includes determining a profile of two opposite edges of the collimator slit in a longitudinal direction thereof based on the following: a vertical distance between a focus of a radiation source to the collimator slit, a vertical distance between the focus and the radiation detector, an inclination angle between adjacent detector elements, a length of each detector element, a desired width of projection on the radiation detector by the radiation rays passing through the slit whose longitudinal edge profile is to be determined, and an offset angle of a connecting line from a point on a longitudinal center line of the slit to the focus relative to a plane passing said focus and perpendicular to the slit.
