In this study, synthesis of copper nanoparticles and effect of the reaction conditions on the particle size were investigated. The copper nanoparticles were synthesized and stabilized in a narrow temperature range in the presence of polyvinylpyrrolidone under nitrogen atmosphere. Reaction temperature and concentration ratio of the reducing agent to the precursor (R/P) as two main conditions i...
Introduction: In the present study, the effects of oral morphine consumption in pregnant female rats on the amygdaloid complex development in the embryos were investigated. Methods: Female Wistar rats weighing 250-300 g (n=15) were divided into control (n = 8) and experimental groups (n = 7). The experimental group received morphine (0.05 mg/ml) in their tap water. On the 19th day of pregnan...
