Early Life & Education

Helena Birecka (born May 13, 1921) was a Polish and American scholar and colleague who demonstrated exceptional intelligence throughout her professional journey. Helena earned her master’s degree from the Agricultural University in Perm, Russia, and later achieved her Ph.D. from the prestigious Timiriazev Agricultural Academy in Moscow. She taught biochemistry and plant physiology and was also the leader of an active research program that focused on alkaloid biochemistry in plants. Helena embraced a diverse linguistic background as she spoke multiple languages such as Polish, English, French, Russian, and German. Some of her outstanding works include positions as a research associate at Yale University in Connecticut and she served as a professor at the University of Istanbu l in Turkey and the University of Brazil in Rio de Janeiro.

Helena was a professor at both the Agricultural University and the Polish Academy of Sciences in Warsaw, Poland before she migrated to America. She conducted research at the Central Isotope Laboratory in Pulawy, Poland, and the International Atomic Energy Agency in Vienna, and also supervised over 20 Ph.D. students, primarily from Poland. In 1975, she made history as the first female member of the teaching faculty at Union College. During her tenure, she demonstrated expertise and encouraged numerous students to pursue their master's degrees through challenging academic pursuits.

Research & Projects

Helena was engaged in numerous international scientific meetings and evaluated research proposals for prestigious organizations such as the National Science Foundation and the National Institutes of Health. She also assessed manuscripts submitted for publication in scientific journals and has made significant contributions to various studies and research projects.

Some of these studies include “Cell Wall and Protoplast Isoperoxidases in Tobacco Plants in Relation to Mechanical Injury and Infection with Tobacco Mosaic Virus,” This study focused on analyzing the isoperoxidase patterns in different tobacco varieties (Turkish, Wisconsin 38, and Samsun NN), each displaying varying levels of sensitivity to the tobacco mosaic virus. The research revealed that isoperoxidases responded similarly to both infection and mechanical injury, suggesting a nonspecific reaction to these stimuli. It also identified the presence of peroxidase in various cellular components in infected tissues, including the endoplasmic reticulum, Golgi apparatus, vacuole, cell wall, and intercellular spaces. “Endogeous polyamine levels and darkness induced leaf senescence” revealed that when oat seedlings and Heliotropium indicum plants were exposed to difluoromethylarginine, either alone or in combination with difluoromethylornithine, their arginine decarboxylase activity was significantly reduced (by approximately 60-90%) over a 13-day period. “Pyrrolizidine alkaloids of Heliotropium spathulatum”. This study presents the isolation and structural characterization of pyrrolizidine alkaloids from Heliotropium spathulatum. Utilizing various spectroscopic techniques, eight known alkaloids, namely lycopsamine, amabiline, curassavinine, coromandalinine, heliovicine, coromandaline, and curassavine, were identified, alongside the discovery of two previously unknown pyrrolizidine alkaloids, heliospathine and heliospathuline.
