Dielectric properties of human ovary follicular fluid at 9.2 GHz.

The influence of the follicle size, rapid freezing to -196 degrees capital ES, Cyrillic and cryopreservation in liquid nitrogen within a period of one month of the human ovary follicular fluid (FF) on its dielectric properties is studied by the microwave dielectric method. The FF was obtained from dominant follicles of patients who received treatment for infertility by extracorporal fertilization. We have measured the real part (epsilon') of the complex permittivity of the native and frozen follicular fluids at the room temperature.

Using UHF-dielectrometry to study protein structural transitions.

UHF-dielectrometry method is based on the following facts: i) there is dispersion (i.e. dependence on frequency) of the dielectric permeability epsilon; ii) bound and free water have remarkable different epsilon, mobility and dispersion regions; iii) conformational changes in a macromolecule lead to redistribution of free and bound water and to change of the amount of free water molecules.
