Background With considering the importance of natural products for their remedial and therapeutic value, this research was aimed to analyze the chemical compositions and antimicrobial activity of four propolis samples from different areas of Iran (Chenaran, Taleghan, Morad Beyg, and Kalaleh) with various climates and flora. Methods Ethanolic (70% EtOH) and dichlromethane (DCM) extracts of Ira...

BACKGROUND Eradication of malaria will depend on discovery of new intervention tools such as anti-malarial drugs. Due to the increasing interest in the application of propolis against significant clinical pathogenic agents, the aim of the present investigation was to evaluate the anti-plasmodial effect of Iranian propolis extracts against chloroquine (CQ)-sensitive Plasmodium falciparum 3D7 and...

Taxonomic Recent trends in the management of water supply have increased the need for modeling techniques that can provide reliable, efficient, and accurate representation of the nonlinear dynamics of water quality within water distribution systems. Since artificial neural networks have been widely applied to the nonlinear transfer function approximation, in this study we present an empirical m...
