Group activities

The basic aim of the working groups of the National Laboratory for Reproduction is to approach embryo - endometrial dialogue on embryos with non- invasive methods.
The FIR group aimed to investigate whether there is a difference measured by more sophisticated physical methods in energy release of between embryos with good viability and reduced viability, and thus reduced implantability.
We are encouraged by the fact that microchip-controlled micro-calorimetric measurements have been obtained to measure the energy output of cells and animal embryos with data comparable to those of classical chemical methods.
1., Far infrared measurements
First area of our experiments is the search for differences in electromagnetic radiation in the far infrared range, namely in the wavelength range of 8-14 thousand nm. The tests are based on the physical factor of the human body, as in terms of heat release it operates as an absolute black body, and its heat dissipation is most intense in the 8-14 micron wavelength range mentioned above. On the other hand, the heat release of the living embryo is exothermic, and the degenerate embryo’s heat release is 0. The practical difficulties of the method are the production of cell culture-grade devices with adequate transmittance in the wavelength range of 8-14 μ.
2., Photon emission from embryos
Another direction of our study is to detect possible differences in the photon emission of the embryo. The photoelectron emission measurements available today are so sensitive and noise-free that differences at the cellular level can be detected by fluorescence techniques. The leap point of our measurements is whether the non-light-induced genomic photon emission of a living embryo is at a level that can detect even small differences between two objects (well and poorly implanted) with today's technique.
3., Bioimpedance
The ability of cells and cell groups to conduct electricity depends on the amount and arrangement of the components that conduct better and worse. Bioimpedance can be measured with today's technology even at extremely low voltages and currents. Despite possible measurable differences in animal testing, the fundamental concern remains that the method should not be considered non- invasive even at the lowest possible voltage.
