FTIR spectroscopy characterization of fatty-acyl-chain conjugates.

FTIR spectroscopy is used to identify poly-L-lysin fatty-acyl-chain (PLL-FAC) conjugates based on structural differences found between FAC species. Twenty-one PLL-FAC models were used, from C8 to C24, and with up to 5 unsaturation levels (C20:5). Curve fitting of the 3050-2800 cm(-1) spectral interval permitted extraction of IR bands belonging to the stretching vibration modes of methyl, methylene, and alkene groups.

GEMSP: a new therapeutic approach to multiple sclerosis.

A new therapeutic approach called Endotherapia (GEMSP) for the treatment of Multiple Sclerosis (MS) is suggested. Endotherapia is the result of an immunopathological strategy addressing chronic incurable diseases with a multifactorial etiology. This approach combines a biomedical evaluation of circulating immunoglobulins directed against specific self-antigens and self-antigens modified by free radicals.
