Resumo
Fourier-transform infrared (FTIR) imaging spectroscopy
was used to investigate biochemical alterations in
cardiac tissue samples treated with Interleukin-1beta (IL-1β).
Linear Discriminant Analysis (LDA) was applied to spectra in
the 1500–1800 cm−1 region. In this work, the LDA component
score for each pixel was plotted as a heatmap, enabling spatial
visualization of spectral alterations. Heatmaps were generated for
each of the three control and three treated samples. Additionally,
the LDA loading curves show the induced alterations across
wavenumbers.
