1. Does Anzer Propolis Have a Protective Effect on Rabbit Spinal Cord Ischemia/Reperfusion Injury?*
Abstract Introduction: In this study, Anzer propolis, which can only be obtained from the Eastern Black Sea region in Turkey, is studied for its effect on spinal cord ischemia/reperfusion injury. Methods: A total of 12 healthy male New Zealand White rabbits with an average weight of 3.0 to 3.5 kg were separated into two blind and randomized groups: the isc

2. Chemical profile and antioxidant activity of geopropolis from Melipona subnitida collected inside and outside the nest
Melipona subnitida (“jandaíra”) is a species of stingless bee endemic to the Caatinga, a dry forest in the northeastern Brazilian semi-arid. Propolis is a product containing beeswax and plant resin. It contains compounds that can be able to prevent health problems by protecting cells against damage by oxidative agents. M. subnitida produces geopropolis,

3. Optimization of ultrasound-assisted extraction of turkish propolis and characterization of phenolic profile, antioxidant and antimicrobial activity
Abstract This study aimed to determine optimum conditions of the ultrasound assited extraction (UAS) parameters for different solvent types by using response surface methodology (RSM) and Box- Behnken design. The model parameters namely, time, temperature and ultrasound power significantly affected TPC value of the propolis extract (P < 0.05). The optimum pr

6. Atomic force microscopy evidences of bacterial cell damage caused by propolis extracts on E. coli and S. aureus
Abstract The interaction of the aqueous extract of green propolis with the bacterial envelope was investigated using atomic force microscopy on E. coli and S. aureus, as Gram-negative and Gram-positive model microorganisms. The bacteria were incubated in the extracts with variable proportions of water/ethanol, i.e., in different concentrations of total pheno

7. Effect of Propolis on Streptococcus mutans Biofilm Formation
Abstract Objective: To evaluate the susceptibility of S. mutans during growth as a biofilm in the presence of different concentrations of propolis. Material and Methods: Three different concentrations of ethanolic extract of propolis (10%, 5%, and 2.5%) were used to evaluate its potential to attenuate the biofilm formation of S. mutans (ATCC 25175) on micr

8. Effects of MTA and Brazilian propolis on the biological properties of dental pulp cells
Abstract: The aim of this study was to evaluate the effect of mineral trioxide aggregate (MTA) and Brazilian propolis on the cell viability, mineralization, anti-inflammatory ability, and migration of human dental pulp cells (hDPCs). The cell viability was evaluated with CCK-8 kit after 1, 5, 7, and 9 days. The deposition of calcified matrix and the expressi
