After Zn2+ finger-mediated binding to a DNA break, poly(ADP-ribose) polymerase becomes automodified with long polymers of ADP-ribose. These nucleic acid-like polymers may facilitate DNA repair by noncovalently interacting with neighboring proteins. Using a novel screening technique, we have identified histones as the predominant poly(ADP-ribose)-binding(More)
A randomly amplified polymorphic DNA (RAPD) analysis was performed for the molecular typing of Mycobacterium avium strains. This method was applied to epidemiologically unrelated M. avium strains isolated from the blood of 10 different AIDS patients and to strains that were considered epidemiologically related, as they had been isolated from the same(More)
This paper will review the literature in order to define lesion characteristics that determine decision for surgical or endovascular therapy in patients with chronic critical limb ischemia (CLI). The typical pattern of disease is multilevel, infrainguinal disease. The great majority of patients with CLI can be treated by endovascular means, and the(More)
