“…There are many examples of how overlapped infrared spectra can be enhanced and greatly improve their information content. One of them is estimation of protein secondary structure and conformations by the analysis of the resolution-enhanced amide I profile by FSD [78]. Thus the FSD-IR was used to extract individual components from a composite band of N-H and C=O groups.…”

“…Dentre essas técnicas o FTIR vêm apresentando grandes avanços 2,3,4 pois além de ser uma técnica rápida, permite que a amostra seja analisada em vários ambientes como solução aquosa 3,4,5 , sólido amorfo 6 ou cristalino 3 , filmes 3,6,7,8 , membranas 3,4,5,9 , pastilhas de KBr 10 , além dos espectrômetros de FTIR serem mais facilmente encontrados do que os de Raman e Dicroísmo Circular.…”

“…Como todos esses sinais podem estar presen-E-mail:lucimara@cnpdia.embrapa.br; E-mail:rubens@cnpdia.embrapa.br; E-mail:colnago@cnpdia.embrapa.br tes numa única proteína, a banda de amida I é uma banda altamente complexa, onde esses componentes não são observados individualmente 5 . Assim o processo de quantificação das ESP a partir de espectros de FTIR envolve o uso de métodos matemáticos como os de aumento de resolução e reconhecimento de padrões [3][4][5]6,8 . Desses métodos os de aumento de resolução são os mais usados 4 e serão analisados neste trabalho.…”

“…35 The Raman and infrared spectroscopy studies of the lens proteins have shown that the predominant protein conformation found in the normal mammalian lenses is the b-pleated sheets. 36,37 Frederikse et al, 38 using amyloidophilic stains of Congo red and thioflavine, revealed that the b-sheet arrays of mammalian crystalline lenses own an amyloid-like supramolecular order in interior fiber cells. In this study, as a positive control, histologic sections of the brain tissue from an individual previously diagnosed with AD also were stained.…”
