(Tg) growing in the area of Tebessa in the eastern pa Read More

Background: Propolis is a natural resinous material produced by honeybees. The biological activity and phenolic profile of propolis were largely studied all over the world. However, only a few investigations have been carried out on Algerian and Turkish propolis. The aim of the present study was to compare the phenolic content, antioxidant, and antibacterial activity of propolis samples collected from different localities of Alge Read More

Background: Pollen and propolis are two bee products with highly health promoting properties. But there are some limitations of raw propolis usage not only in daily consumption but also in putting it in food formulations. Propolis should be extracted to convert it into consumable form and ethanol is the first choice as a solvent. But ethanol consumption, either in health-wise or religious aspect, is one of the factors limiting the usage Read More

The appropriate selection of initial receptor structure has been the "cornerstone" or foundation of successful structure-based virtual screening (SBVS), and plagued the structure-based design with a significant practical problem to determine the major physiological states or important transition states of receptors (e.g. proteins with multiple low-energy conformations and liganddependent conformational dynamics). It is Read More
