“…By means of the HCA, it was possible to identify the distribution of spectral data obtained in depth in two main groups according to similarity 27,28 (Figure 1) comprised of frames 1–8 and frames 9–16. Figure 1 also shows the keratin profile in relative amounts varying as a function of depth at basal conditions (T0), since keratin is synthesized in the basal layer of the epidermis and the accumulation of its disulfide bonds occurs with the proliferation of keratinocytes from the lower regions of the SC to the outermost 7,29 while it assumes different secondary and tertiary structures through the SC 16,21 .…”

“…25 Unsupervised hierarchical clustering analysis (HCA) was performed on pre-processed data aiming to group data from each data point analyzed, based on the distance measure, and the identification of similarities and differences between spectra groups. 27,28 Spectra were grouped with regard to the 1070-1800 cm −1 spectral range, relevant to the analysis of lipids and keratin. By means of the cluster analysis, the surface and average SC thickness were estimated and applied to determine the limits of integration of the areas under the curves (AUCs) of the average semiquantitative profiles of each component.…”

“…Estes resultados confirmam a hipótese de que o DFC pode ser validado pela vazão, pois de acordo com os resultados, eles não são independentes e estão altamente relacionados e sua eficiência pode assim ser confirmada (AYRES et al, 2007;BOGO et al, 2010). Helfer et al (2006)…”

“…Em doses baixas, a levoanfetamina produz maior excitação que a dextroanfetamina. Em doses mais elevadas, as propriedades estimulantes da dextroanfetamina são de 3 a 4 vezes mais intensas que aquelas produzidas pela levoanfetamina (BERMAN et al, 2009;HEAL et al, 2013 (BERGO, 2007;DE BRABANTER et al, 2013;LI et al, 2013;MAURER, 2005MAURER, , 2007bMAURER, , 2012 1998;HAIR JR et al, 2009;JOHNSON;WICHERIN, 2007;NETO, 2004;PARREIRA, 2003;REIS, 2002;RINGNÉR, 2008;WERNER, 2003 grupos formados e a similaridade entre as amostras e/ou variáveis (BRATCHELL, 1989;HAIR JR et al, 2009;HELFER et al, 2006).…”
