Prospective cohort 20 years after endovascular treatment for abdominal aortic aneurysm.

Objective: To describe the factors associated with survival 20 years after endovascular treatment of an abdominal aortic aneurysm (AAA) in a single center.

Methods: Prospective cohort of asymptomatic patients with an infrarenal aortic aneurysm treated with a bifurcated endovascular graft (Talent) between June 1997 and August 2008. Cox proportional hazard multivariable regression was used for analysis of independent risk factors for survival.

The Process of Separating Bovine Serum Albumin Using Hydroxyapatite and Active Babassu Coal (Orbignya martiana).

Bovine serum albumin is one of the major serum proteins; it plays an important role as a result of its functional and nutritional properties which have bioactive peptides. Adsorption method was used to separate protein, which involves hydroxyapatite, synthetic hydroxyapatite, and active babassu coal. Initially, characterization was carried out using the zeta potential of the adsorbents.

A 10-year single-center prospective study of endovascular abdominal aortic aneurysm repair with the talent stent-graft.

Purpose: To report a 10-year prospective study of patients submitted to endovascular treatment for infrarenal abdominal aortic aneurysms (AAA).

Methods: Between June 1997 and June 2007, 337 patients (284 men; mean age 72.5+/-7.
