25. Avaliação do estresse oxidativo em ilhotas pancreáticas humanas e em cultura de células INS-1E / Evaluation of oxidative stress in human pancreatic islets and INS-1E cells culture
Human pancreatic islet transplantation is considered a promising strategy to cure the cure Diabetes Mellitus type I. However, transplantation efficiency is dramatically affected by sub-optimum islet recovery in the isolation/purification procedure and islet viability after transplantation. Isolated pancreatic islets are obtained through collagenase perfusion

26. Contra a Doutrina "Bush": preempção, prevenção e direito internacional / Against "Bush Doctrine": Preemption, Prevention and International Law
This thesis intends to refute the so-called "Bush Doctrine", whose terms have been laid down in the National Security Strategy of the United States of America in 2002, and have since then oriented the present Administrations foreign policy towards a greater assertiveness of military power against either present or future threats to its dominant position in i

27. Mitral valve replacement with complete chordae tendinae preservation in end-stage dilated cardiomyopathy. / Substituição da valva mitral com tração e fixação dos músculos papilares em pacientes com miocardiopatia dilatada
Background. We aimed to evaluate mitral valve replacement results and a new technique for complete chordae tendineae adjustment for left ventricular remodeling. Methods. Twenty end-stage idiopathic dilated cardiomyopathy patients with severe functional mitral valve regurgitation underwent mitral valve replacement from July 2000 to December 2003. Three (15%)

28. PRECONDITIONING OF ORGAN DONORS WITH LOW LEVELS OF CARBON MONOXIDE REDUCES GRAFT IMMUNOGENICITY AND IMPROVES LONGTERM ALLOGRAFT FUNCTION
Background: Chronic rejection remains the major obstacle for successful transplantation, and to date there is no effective treatment. Events occurring prior to organ transplantation such as brain death, harvesting procedure, and ischemia-reperfusion injury lead to unspecific inflammatory damages danger signals - that increase graft immunogenicity and reduce

29. In situ hypothermic perfusion of the liver versus standard total vascular exclusion for complex liver resection / "Perfusão hipotérmica in situ versus exclusão vascular total do fígado para ressecções hepáticas complexas"
OBJECTIVE. To compare the results of liver resection performed under in situ hypothermic perfusion vs standard total vascular exclusion (TVE) of the liver <60 minutes and ≥ 60 minutes in terms of liver tolerance, liver and renal functions, postoperative morbidity and mortality. SUMMARY BACGROUND DATA. The safe duration of TVE is still debated. Promisin

30. SubpopulaÃÃes de linfÃcitos CD4, CD8 e CD45RB em enxertos esplÃnicos autÃlogos heterotÃpicos de camundongos sadios e esquistossomÃticos: estudo comparativo com o baÃo intacto e o remanescente esplÃnico vascularizado
Schistosomiasis mansoni is an infectious disease caused by a worm (Schistosoma mansoni), which has the human as one of the definitive hosts in its evolutive course. In more advanced stages, massive embolization by eggs layed in the portal venous sistems by adult forms of the parasite to the hepatic parenchima occurs; this leads to inflammatory reactions in t

31. Glandectomy with preservation of corpora cavernosa in the treatment of penile carcinoma
INTRODUCTION: The objective of this work is to describe a conservative surgical technique as an alternative to classic penile amputations, aiming the local control of the disease, in addition to trying to preserve the patient's sexual function. SURGICAL TECHNIQUE: After a circular incision of the skin around the penis, the subfascial plane is developed until

32. Abordagem videolaparoscópica de cisto esplênico não parasitário
A rare case of primary splenic cyst is shown in a young woman who had a left subcostal abdominal pain. Abdominal echography and CT scan revealed a cyst of the anterior aspect of the spleen. A sorologic test for hidatic disease was negative. On the basis of a presumed diagnostic of nonparasitic cyst, the patient was referred to a laparoscopic decapsulation wi

33. The Cardiac Donor: Selection, Preoperative Care, and Organ Procurement and Preservation
A successful cardiac transplant starts with the selection of an appropriate donor. Once consent to organ donation has been obtained, the donor should be managed aggressively in order to maintain optimal organ function. In the case of multi-organ donation, the heart is the first organ to be prepared, as well as the first to be removed. By means of simple pres

35. Minnesota system corneal preservation.
The clinical and laboratory results with a modified Minnesota system of organ culture corneal preservation are presented. A refinement of our preservation technique using a closed system, as well as the addition of chondroitin sulphate to the medium is presented. Laboratory results show preservation of corneal endothelial integrity for at least 21 days with

36. Restoration of the cAMP second messenger pathway enhances cardiac preservation for transplantation in a heterotopic rat model.
Current organ preservation strategies subject graft vasculature to severe hypoxia (PO2 approximately 20 Torr), potentially compromising vascular function and limiting successful transplantation. Previous work has shown that cAMP modulates endothelial cell (EC) antithrombogenicity, barrier function, and leukocyte/EC interactions, and that hypoxia suppresses E
