WebIn this study, FTIR spectra of skin gelatins derived from shaari (a warm water fish) using different conditions were determined and compared to bovine and porcine gelatins, in an effort to elucidate changes in secondary structure that occur during the conversion of collagen to gelatin. WebBackground/aim: Mid-infrared spectroscopy (4000-500 cm -1) was used to analyze the spectral changes and differences of the characteristic absorption bands of the skin components due to cancer development for early clinical diagnosis. Materials and methods: Human biopsies from basal cell carcinoma, malignant melanoma, and nevus were used, … WebThe barrier function of skin resides in the lipid components of the stratum corneum, particularly their spatial organisation. FTIR spectroscopy has already been used as a relevant tool to study this lipid organisation: IR vibration band shifts have been attributed to the variations in lipid organisation induced by temperature. profitable plants to grow indoors
