The search for better surgical repair of nerve injuries should be aimed at uncovering alternatives that not only are efficient, but also enhance nerve growth. The purpose of this study was to compare functional nerve responses following repair with either a traditional microsuture technique or Quixil human fibrin sealant. Thirty female Lewis rats received(More)
The results of nerve repair with fibrin glue and microsuture were evaluated in rat nerve transection models. Ninety Wistar-Furth rat median nerves were exposed, transected, and repaired in an end-to-end fashion with one of four substances/techniques: 1) human fibrin sealant (Quixil); 2) autologous graft and human fibrin sealant (Quixil); 3) bovine fibrin(More)
Helicobacter pylori infection is relevant, due to its role in different gastric pathologies; there are several diagnostic methods, which are divided into invasive and non-invasive. In the first category histology has been considered the gold standard, while other methods include imprint with Gram stain and rapid urease test, which can produce dependable(More)
Progenitor cell transplantation has been considered as a potential angiogenesis therapy for the ischemic hindlimb. In this work we performed an ischemic hindlimb model in dogs. We ligated the middle sacra and the external right iliac arteries. After 7 days, the femoral artery was ligated and removed, and three Silastic tubes were inserted into the gracilis(More)
We established a comparative model of angiogenic induction in previously formed fibrocollagenous tunnels in rat inner thigh muscles. A unilateral hindlimb chronic ischemia model was performed in male Sprague-Dawley rats. A device was then inserted in the central portion of the inner thigh muscles. Vascularity in the ischemic limb was determined by means of(More)
Critical limb ischemia is a medical condition that decreases blood flow and limb oxygen supply; this disease in its late stages of progression leads to only two possible options: either surgical bypass revascularization or limb amputation. We investigated a novel method using autologous transplantation of progenitor cells derived from mobilized peripheral(More)
BACKGROUND Whether H. pylori infection plays a role in FD is ill defined; however, it is recommended to prescribe eradication treatment in patients with dyspepsia without alarm symptoms. Results of this advice are controversial, principally due to absence of instruments that provide an objective measure of changes in symptoms and quality of life. (More)
