Study type: Medical/biological study (experimental study, theoretical study)

Formulation of ELF magnetic fields' effects on malondialdehyde level and myeloperoxidase activity in kidney using genetic programming med./bio.

Published in: Comput Methods Programs Biomed 2007; 86 (1): 1-9

Aim of study (acc. to author)

This study was designed to investigate whether effects of extremely low frequency magnetic fields on malondialdehyde level and myeloperoxidase activity can be appropiately analysed and formulated by a computer method.

Background/further details

A total of 54 male, 250-300 grams weighted, 10-12 weeks old, guiena pigs were used. Experimental results were compared to the results calculated by use of genetic programming (GP). Genetic programming belongs to evolutionary algorithms based on the principles of genetics and natural selections. It can be applid when biological effects are not measurable precisely as in this study the myeloperoxidase activity.
