1. Predicting outcomes in partial nephrectomy: is the renal score useful?
ABSTRACT Introduction and Objective The R.E.N.A.L. nephrometry system (RNS) has been validated in multiple open, laparoscopic and robotic partial nephrectomy series. The aim of this study was to test the accuracy of R.E.N.A.L. nephrometry system in predicting perioperative outcomes in surgical treatment of kidney tumors <7.0cm in a prospective model. Mate

2. Long-term efficacy of endovascular vs open surgical repair for complicated type-B aortic dissection: a single-center retrospective study and meta-analysis
This study aimed to evaluate the long-term survival and risk factors of traditional open surgical repair (OSR) vs thoracic endovascular aneurysm repair (TEVAR) for complicated type-B aortic dissection (TBAD). A total of 118 inpatients (45 OSR vs 73 TEVAR) with TBAD were enrolled from January 2004 to January 2015. Kaplan-Meier curves and Cox proportional haza

3. Detrusor after-contraction: a new insight
ABSTRACT Aims: Detrusor after-contractions (DAC) are non-common in adults. Both definition (nothing in ICS reports) and significance (artefact, link with detrusor overactivity (DO) or bladder outlet obstruction (BOO)) remain discussed. Our purpose was to carry out an analysis of the urodynamic parameters during voidings wi

4. Análise de expressão de micro RNA em carcinoma urotelial de bexiga / Analysis of micro RNA expression in bladder urothelial carcinoma
Introduction: Bladder cancer (BC) is the second most common malignancy of the urinary tract, with 386,000 cases estimated and 150,000 deaths in 2011. Urothelial carcinomas (UC) represent 95% of BC cases, and knowledge of the molecular pathways associated with BC carcinogenesis is crucial to identify new diagnostic and prognostic biomarkers, and development o

5. The slope of the oxygen pulse curve does not depend on the maximal heart rate in elite soccer players
INTRODUCTION: It is unknown whether an extremely high heart rate can affect oxygen pulse profile during progressive maximal exercise in healthy subjects. OBJECTIVE: Our aim was to compare relative oxygen pulse (adjusted for body weight) curves in athletes at their maximal heart rate during treadmill cardiopulmonary exercise testing. METHODS: A total of 180 e

6. Prognosis of colorectal cancer with liver metastasis: value of a prognostic index
The objective of the present study was to explore the factors related to the prognosis of colorectal cancer (CRC) and to establish a prognostic model for the selection of patients who might benefit from hepatic resection for metastatic CRC. A total of 293 patients undergoing liver resection for metastatic CRC (172 males and 80 females ranging in age from 26

9. Avaliação de fatores de risco para cardiopatia isquêmica e valor prognóstico de critérios diagnósticos de cardiopatia isquêmica em pacientes com Diabetes Mellito tipo 2
O diabete melito (DM) está associado a um aumento de 2 a 3 vezes na prevalência de doença cardiovascular, sendo a cardiopatia isquêmica (CI) a principal causa de morte em pacientes com DM tipo 2 (DM2). Em pacientes com DM2, a avaliação dos fatores de risco e a análise completa dos métodos diagnósticos capazes de alterar o prognóstico cardiovascular

10. Biochemical and functional studies of twenty sildenafil analogues in human platelets and in the rabbit corpus cavernosum and aorta / Estudos funcionais e bioquimicos de vinte analogos do sildenafil em plaquetas humanas, corpo cavernoso e aorta de coelho
Sildenafil, a cGMP-specific phosphodiesterase-5 (PDE5) inhibitor, is used for the treatment of erectile dysfunction. In the search for a potent and selective PDE5 inhibitor, new sildenafil analogues (6a-v), characterized by the presence on the sulphonyl group in the 5 position of novel N-4-substituted piperazines or ethylenediamine moiety, were synthesized.

11. Biossensor enzimático para detecção de fungicidas ditiocarbamatos: estudo cinético da enzima aldeído desidrogenase e otimização do biossensor
Initially, all major factors that affect the rate of the AldH-catalyzed reaction (enzyme concentration, substrate concentration, temperature and pH) were investigated. Optimal activity was observed between pH values of 7.5 and 9.5 in the temperature range of 25 to 50 ºC. Kinetic parameters, such as Km (2.92 µmol L-1) and Vmax (1.33 10-2 µmol min-1) demons

12. A cryptosystem for elliptic curves over GF(2m) implemented in FPGAs / Um sistema criptografico para curvas elipticas sobre GF(2m) implementado em circuitos programaveis
Este trabalho propõe um sistema criptográfico para Criptografia baseada em Curvas Elípticas (ECC). ECC é usada alternativamente a outros sistemas criptográficos, como o algoritmo RSA (Rivest-Shamir-Adleman), por oferecer a menor chave e a maior segurança por bit. Ele realiza multiplicação de pontos (Q = kP) para curvas elípticas sobre corpos finitos
