Antibacterial activity of propolis-based toothpastes for endodontic treatment [PDF]
This study evaluated the antibacterial activity of propolis-based toothpastes used as intracanal medication in endodontic treatment. The propolis-based toothpastes were prepared using an extract established in previous studies (identified as A70D and ...

Ex vivo model for studying polymicrobial biofilm formation in root canals
Endodontic disease has mainly a microbial origin. It is caused by biofilms capable of attaching and surviving in the root canal. Therefore, it is important to study the conditions in which those biofilms grow, develop and colonize the root canal system ...

Over-expression of Tgs1 in Mycobacterium marinum enhances virulence in adult zebrafish
Mycobacterium tuberculosis (Mtb), the causative agent of tuberculosis (TB), can persist in the host for decades without causing TB symptoms and can cause a latent infection, which is an intricate challenge of current TB control.

Consumption of phosphates from medium by activated sludge bacteria under various conditions of aeration [PDF]
The ability to consume phosphates from the medium has been assessed for bacteria isolated from activated sludge. There was selected an isolate, which cells has the highest level of phosphorus accumulation. It is shown that the most efficient consumption

Climate change and temperature dependent biogeography: oxygen limitation of thermal tolerance in animals [PDF]
Recent years have shown a rise in mean global temperatures and a shift in the geographical distribution of ectothermic animals. For a cause and effect analysis the present paper discusses those physiological processes limiting thermal tolerance.
