My name is RNDr. Anna Uhrinová, PhD. I work as an assistant professor at the University of Veterinary Medicine and Pharmacy in Košice. During my doctoral studies at the Pavol Jozef Šafárik University in Košice, I focused on the preparation of nickel coordination compounds based on maleate and fumarate ligands. Currently, we are focused on the preparation and characterization of biologically active substances obtained from cultivated mushrooms of the genus Cordyceps and Ganoderma. Currently, we are studying the complexation of heavy metals (silver, nickel, iron) with these mushrooms. Given that due to the constant and inadequate collection of these mushrooms (Cordyceps), their complete destruction in their environment occurs, we are looking for possibilities for their artificial cultivation. By searching for optimal conditions, the presence of biologically significant substances, whose presence in the extracts is responsible for pharmacological efficacy, is simultaneously monitored.
