RESUMO

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 pathoanatomical pattern of disease dictates the choice of treatment modality. Long iliac artery occlusions, in particular, if associated with common femoral artery pathology and long superficial femoral artery occlusions crossing the knee joint so far remain a domain of surgery. However, there is an ongoing shift from surgery to endovascular treatment.

RESUMO

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 patient but from different body locations (4 patients, 10 strains). Three oligonucleotide primers among the six tested were found to generate RAPD profiles with DNA from all M. avium strains and to successfully type them. This method for the typing of M. avium strains is rapid and easy to perform.

RESUMO

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 species in human keratinocytes, rat hepatocytes, frog eggs, and yeast. Polymer binding is confined specifically to the histone domains responsible for DNA condensation, i.e. histone tails. Our results indicate that polymers of ADP-ribose are targeted to sites of DNA strand breaks by poly(ADP-ribose) polymerase and subsequently function to alter chromatin conformation through noncovalent interactions with histone tails.
