Prostate cancer is the second cause of cancer death in Brazilian men. One of the relevant phenomena to the inherited susceptibility is the presence of allelic variants in genes involved with the DNA repair pathway. The aim of this study was to analyze the frequencies of prevalent, heterozygous and rare genotypes of the base excision repair genes APEX1 and(More)
Numerous enzymes, including Cytochrome P450s (phase I) and Glutathione-S-transferases (phase II), are involved in the metabolic activation and detoxification of carcinogens. Epidemiological studies have consistently demonstrated that bladder cancer is strongly associated with cigarette smoking, and the risk for the development of this neoplasia may be(More)
To test the effect of exogenous surfactant on the evolution of histopathologic changes of bronchopulmonary dysplasia (BPD), we conducted a study in a premature baboon hyaline membrane disease model. One hundred mg/kg bovine surfactant sonicated in saline or 3 ml/kg saline placebo was instilled via the trachea at about 10 min of age. The clinical status and(More)
To evaluate the temporal changes in cerebral energy metabolism in shock during the perinatal period, we studied cerebral blood flow (CBF) and other metabolic variables in newborn piglets subjected an acute hypovolemic hypotension (HVH). By 30 minutes following HVH, the cardiac output dropped 64%, but the CBF was maintained. Serum glucose rose 110% baseline,(More)
Background: There is little information available on follow-up of abdominal aortic aneurysm patients treated with endovascular repair using vascular ultrasonography in Brazil or on how it compares with the results of angiotomography. Since ultrasonography is an examination that is risk-free, inexpensive and widely available, it is a very attractive method.(More)
Introduction: The majority of cases of stenosis or occlusion of central veins are the result of central catheters, arteriovenous fistulas, neoplasms or traumas and these conditions can cause severe cases of venous hypertension or reduce the flow through fistulas. The objective of this study is to analyze the results of central venous angioplasties conducted(More)
Es wird über die gleichzeitige Erkrankung einer Trisomie 21 mit einer cystischen Pankreasfibrose bei einem Säugling berichtet. Ein bisher unbekannter, zusätzlicher Aspekt ist das Auftreten einer hypoplastischen Thrombocytopenie. This is a report about Trisomie 21 and cystic fibrosis in a newborn. At the same time the infant had a hypoplastic(More)
Because the issue of optimal time for artificial surfactant therapy for hyaline membrane disease has not been established, the effects of treatment with a reconstituted bovine surfactant (surfactant TA) were compared at two time periods in a hyaline membrane disease model in a premature baboon. The baboons were delivered by cesarean section at 75% of(More)
