Contamination of primary and cell cultures by mycoplasmas is one of the main economic and biological pitfalls in basic research, diagnosis and manufacture of biotechnological products. It is a common issue which may be ...

Objectives: The effects of propolis and phenolic compounds (caffeic acid – Caf; dihydrocinnamic acid – Cin; p-coumaric acid – Cou) in the same quantity found in our propolis sample were investigated on human laryngeal ...

Propolis is a sticky dark-colored material showing a very complex chemical composition that honeybees collect from plants. It has been used in folk medicine since ancient times, due to several biological properties, such ...
