Achieving K/DOQI Targets with Cinacalcet in Dialysis Patients with Secondary Hy...

Secondary hyperparathyroidism is a common complication of chronic kidney disease. The elevated serum intact parathyroid hormone, phosphorus, calcium and calcium x phosphorus product have been independently associated with an increased relative risk of mortality. The standard therapy for secondary hyperparathyroidism, including active vitamin D analogues and phosphate binders, is often insufficient to allow pati...

Mycophenolate mofetil in chronic glomerular diseases

Comparison among HB-inspired algorithms for continuous-spin systems and gauge f...

We propose a new local algorithm for the thermalization of n-vector spin models, which can also be used in the numerical simulation of SU(N) lattice gauge theories. The algorithm combines heat-bath (HB) and micro-canonical updates in a single step - as opposed to the hybrid overrelaxation method, which alternates between the two kinds of update steps - while preserving ergodicity. We test our proposed algorithm...

Demographic and clinical characteristics of patients receiving dialysis in Port...

Background. Data on human immunodeficiency virus (HIV) infected patients receiving dialysis in Portugal is scarce. Methods. This nationwide epidemiological survey retrospectively evaluates HIV-infected patients on chronic dialysis in Portugal between 1997 and 2002. Results. Sixty-six patients were evaluated (mean age: 39.1±1.6 years, 47 men, 35 black African). Sixty-two patients started dialysis and 4 patients ...

Percolation of Monte Carlo clusters

Percolation theory is of interest in problems of phase transitions in condensed matter physics, and in biology and chemistry. More recently, concepts of percolation theory have been invoked in studies of color deconfinement at high temperatures in Quantum Chromodynamics. In the present paper we briefly review the basic concept of percolation theory, exemplify its application to the Ising model, and present the ...

Classification of Recorded Classical Music: a Methodology and a Comparative Study

As a result of recent technological innovations, there has been a tremendous growth in the Electronic Music Distribution industry. Consequently, tasks such as automatic music genre classification address new and exciting research challenges. Automatic music genre recognition involves issues like feature extraction and development of classifiers using the obtained features. We use the number of zero crossings, l...

A prototype for classification of classical music using neural networks

As a result of recent technological innovations, there has been a tremendous growth in the Electronic Music Distribution industry. In this way, tasks such us automatic music genre classification address new and exciting research challenges. Automatic music genre recognition involves issues like feature extraction and development of classifiers using the obtained features. As for feature extraction, we use featu...

Vamos Recuperar a Ventosa!

Na Maternidade Dr. Alfredo da Costa a atitude dos Obstetras face à ventosa tem vindo a mudar ao longo dos tempos. Após o período áureo de utilização da ventosa de Malmström nos anos 70, seguiu-se o declínio progressivo até à década de 90, altura em que praticamente não foi utilizada (0,3% do total de partos). No início do séc. XXI o aparecimento das ventosas maleáveis, em que o estabelecimento do vácuo é mais ...
