FT-IR spectral profiles after peak fitting for the liver DNA from NOD mice.

<p>Normoglycemic mice, A; hyperglycemic mice, B. Spectral range: 2990–2850 cm⁻¹. Software: Grams/AI 8.0; function: Gaussian; sensitivity: low.</p

Savitzky-Golay's second-derivative spectra for the liver DNA from NOD mice.

<p>Detail for the IR spectral window in the 3100–2800 cm⁻¹ range. Normoglycemic mice (N), red line; hyperglycemic mice (H), black line; X axis, wavenumbers in cm⁻¹; Y axis, second derivative. Software: Grams/AI 8.0; 2nd derivative degree: 2, points: 31.</p

Optical anisotropy aspects of the DNA samples extracted for FT-IR analysis.

<p>Birefringence images are shown for the liver DNA from normoglycemic (A,B) and hyperglycemic (C-E) mice. Birefringence brilliance in the outer region of DNA drops dried on slides in A and D was compensated in B and E, respectively (arrows). The bars equal 100 µm.</p

Numerical statistics for the FT-IR –CH₃ band peak in the DNA from NOD mouse liver cell nuclei.

<p>Wavenumber edges: 2987 and 2849 cm⁻¹. Software: Grams; function: Gaussian; sensitivity: low.</p

FT-IR spectral profiles for the liver DNA from NOD mice.

<p>Normoglycemic mice (N), red line; hyperglycemic mice (H), black line; spectral range: 3600–700 cm⁻¹. X axis, wavenumbers in cm⁻¹; Y axis, absorbances (A).</p
