17. Validation of a spectrophotometric methodology for the quantification of polysaccharides from roots of Operculina macrocarpa (jalapa)
The roots from Operculina macrocarpa (L.) Urb., Convolvulaceae, are widely used in Brazilian traditional medicine as a laxative and purgative. The biological properties of this drug material have been attributed to its polysaccharides content. Thus, the aim of this study was to evaluate the polysaccharide content in drug material from O. macrocarpa by spectr

18. In-house method validation and occurrence of alpha-, beta-endosulfan, endosulfan sulphate, lambda-cyhalothrin, procymidone and trifluralin residues in strawberry
A method for determination of organohalogen pesticides in strawberry by gas chromatography with electron capture detection was validated and applied in a monitoring program. Linearity, matrix effects, and day effect were evaluated for the analytes alpha-endosulfan, beta-endosulfan, endosulfan sulphate, lambda-cyhalothrin, procymidone, and trifluralin. The li

20. Severity score system for progressive myelopathy: development and validation of a new clinical scale
Progressive myelopathies can be secondary to inborn errors of metabolism (IEM) such as mucopolysaccharidosis, mucolipidosis, and adrenomyeloneuropathy. The available scale, Japanese Orthopaedic Association (JOA) score, was validated only for degenerative vertebral diseases. Our objective is to propose and validate a new scale addressing progressive myelopath

21. Monitoração dinâmica de asserções para depuração em silício
The increasing demand for shorter time-to-market, combined with increased complexity and performance requirements put a tremendous pressure on post-silicon debug, which is usually the last step prior to chip release. In contrast to pre-silicon techniques, postsilicon debug have two main limitations, controllability and observability, which cause the failure

23. Controle de qualidade e avaliação das propriedades tecnológicas das formas polimórficas de talidomida / Quality control and evaluation of technological properties of polymorphic forms of thalidomide
Thalidomide was widely prescribed between 1950 and 1960, in nearly 50 countries, as sedative and antiemetic for morning sickness during pregnancy. After the occurrence of serious problems of teratogenicity it was heavily controlled. Growing interest has been observed in recent years to identify and elucidate the anti-inflammatory, immunomodulatory and anti-a
