13. Modelo experimental de obstrução ureteral em coelhos / Experimental model of ureteral obstruction in rabbits
The stenosis of the ureteropelvic junction (UPJ) is one of the most frequent congenital anomalies and are clinically important to be treated not only for the quality of life that gets worse, pain and urinary tract infection, but also the loss of the kidney function (1,2,3). So, the study of UPJ model will be used for future treatment. The aim of this study w

14. An improved in vivo method for atrioventricular node ablation via thoracotomy
The atrioventricular (AV) node is permanently damaged in approximately 3% of congenital heart surgery operations, requiring implantation of a permanent pacemaker. Improvements in pacemaker design and in alternative treatment modalities require an effective in vivo model of complete heart block (CHB) before testing can be performed in humans. Such a model sho

15. Evaluation of the ultrastructure and of the movement of cilia in children with chronic and repetition pneumopathies without a defined diagnosis / Avaliação da ultraestrutura e do movimento ciliar em crianças com pneumopatias crônicas e de repetição se diagnóstico definido
INTRODUCTION: Primary ciliary dyskinesia (PCD) is a genetic disorder of the ultrastructure and function of mobile cilia, with consequent impairment of mucociliary clearance, leading to upper and lower airways respiratory infection and infertility. The diagnosis, based on ultrastructure evaluation or genetic scan, is performed according to patient selection a

16. Effect of praziquantel administration on hepatic stereology of mice infected with Schistosoma mansoni and fed a low-protein diet
A study was undertaken to investigate the effect of administering praziquantel (PZQ), focusing on the liver stereological findings of malnourished mice infected with Schistosoma mansoni. Thirty female Swiss Webster mice (age: 21 days; weight: 8-14 g) were fed either a low-protein diet (8%) or standard chow (22% protein) for 15 days. Five mice in each group w

17. AlteraÃÃes vasculares pulmonares em pacientes com fibrose periportal esquistossomÃtica
Background: Mansonic schistosomiasis is an endemic disease in Brazil and can cause disease in different organs The pulmonary vascular pathology, one of the most severe clinical manifestations of this disease, consists mainly of pulmonary arterial hypertension (PAH) and cyanotic syndrome. The PAH is defined by an artery systolic pressure >35mmHg, or mean >25m

18. Immunohistochemical studies of stellate cells in experimental cholestasis in newborn and adult rats
BACKGROUND AND AIMS: Although there is much known about liver diseases, some aspects remain unclear, such as the nature of the differences between the diseases observed in newborn infants and those in adults. For example, how do newborns respond to duct epithelial cell injury? Do the stellate cells in newborns respond similarly to those in adults during bili

19. Endomiocardiofibrose: patologia e correlação clínica em material de ressecção cirúrgica / Endomyocardial fibrosis: pathological findings in surgical specimens and clinicopathological correlation
INTRODUÇÃO: A endomiocardiofibrose (EMF) é uma miocardiopatia de padrão restritivo de etiologia desconhecida, prevalente em regiões tropicais. Caracteriza-se por espessamento fibroso do endocárdio e miocárdio subjacente, comprometendo ponta e via de entrada de um ou de ambos os ventrículos. Sua etiopatogenia é pouco conhecida e muitos autores a asso

20. Mechanisms of arrhythmogenesis in cardiomyocytes and development of in vitro model of cardiac hypertrophy and fibrosis induced by Trypanosoma cruzi / Mecanismos envolvidos na arritmogenese em cardiomiocitos e desenvolvimento de modelo in vitro de fibrose e hipertrofia cardiaca induzidos por Trypanosoma cruzi
Infection with protozoan Trypanosoma cruzi causes Chagas disease that among its manifestations presents a severe cardiac form, which can induce arrhythmias and sudden death. In the first part of this work we studied the effect of T. cruzi infection on host cell coupling and calcium homeostasis in monolayered cardiac myocytes. In moments of invasion of the pa

21. Centrilobular fibrosis (CLF): a distinct histological pattern in systemic sclerosis with interstitial lung disease (ILD) / Fibrose centrilobular (FCL): um padrão histológico pulmonar distinto em pacientes com esclerose sistêmica e doença intersticial pulmonar
Objectives: CLF is a new histological pattern of idiopathic ILD associated to esophageal reflux. We have investigated its presence in SSc with lung involvement. Methods: 28 SSc patients were submitted to open lung biopsy. The specimens were classified according to the new consensus classification of idiopathic interstitial pneumonia and to the diagnostic cri

22. Schistosoma mansoni major egg antigen Smp40: molecular modeling and potential immunoreactivity for anti-pathology vaccine development
The pathogenesis of Schistosoma mansoni infection is largely determined by host T-cell mediated immune responses such as the granulomatous response to tissue deposited eggs and subsequent fibrosis. The major egg antigens have a valuable role in desensitizing the CD4+ Th cells that mediate granuloma formation, which may prevent or ameliorate clinical signs of

23. Efeitos da cirurgia de Fobi-Capella na doença hepática gordurosa não alcoólica (DHGNA): estudo prospectivo de dois anos / Effects of bariatric surgery (Fobi-Capella) in nonalcoholic fatty liver disease (NAFLD): prospective study of 2 years
Background: The incidence of obesity is increasing in western countries at an alarming rate. The National Center for Health Statistics of United Stated estimated in adult population 61% the prevalence of overweight or obesity, and 30% has obesity, and 5 to 6% were classified in severe obesity. In Brazil, the Ministry of Health reported 32.9% the prevalence o

24. Hepatic alterations in severely obese patients: clinical-laboratory and histopatological evaluations before surgical treatment of obesity / "Alterações hepáticas em grandes obesos: avaliações clínico-laboratoriais e histopatológicas antes do tratamento cirúrgico da obesidade"
Nonalcoholic fatty liver disease (NAFLD) and nonalcoholic steatohepatitis (NASH) has been associated with obesity. Determine prevalence of NAFLD/NASH and metabolic syndrome (MS) in severe obesity; define clinical predictor of steatohepatitis; establish histological criteria necessary to diagnose NASH. Evaluation of 325 patients submitted to bariatric surgery
