| failure to shorten the diagnostic delay in two ultra-orphan diseases (mucopolysaccharidosis types i and iii): potential causes and implications. | rare diseases are often un- or misdiagnosed for extended periods, resulting in a long diagnostic delay that may significantly add to the burden of the disease. an early diagnosis is particularly essential if a disease-modifying treatment is available. the purpose of this study was to assess the extent of the diagnostic delay in the two ultra-rare diseases, i.e., mucopolysaccharidosis i (mps i) and iii (mps iii), both of which are lysosomal storage disorders with different phenotypic severities ( ... | 2018 | 29310675 |
| simultaneous determination of six quality parameters of biodiesel through 1h nmr spectroscopy and partial least squares. | biodiesel quality is checked by determining several parameters. considering the large number of analyses in this verification, as well as the disadvantages of the use of toxic solvents and waste generation, multivariate calibration is suggested to reduce the number of tests. in this work, hydrogen nuclear magnetic resonance (1h nmr) spectra were used to build multivariate models, from partial least squares (pls), in order to perform simultaneous determination of six important quality parameters ... | 2018 | 29310312 |
