In vivo Evaluation of Antioxidant Activity of Chamomile Extract against Procyclidine-Induced Oxidative Stress: Potential Application in Cancer Prevention.

The study aimed to investigate the effect of the aqueous extract of the chamomile plant on oxidative stress induced by procyclidine in rats. 30 rats were randomly divided into five groups, with 6 rats in each group. The first group was given distilled water only, while the second group was administered procyclidine (1 mg/kg body weight) in three doses daily for a period of 60 days.

Synthesis of pyrano-pyrimidines: recent advances in catalysis by magnetically recoverable nanocatalysts.

The widespread use of catalysts in chemistry in the current century, especially in multicomponent reactions, has led researchers to design catalysts with high catalytic power and which can be recycled. In recent years, most scientists and researchers of chemical science have become interested in magnetic nanocatalysts and used them to perform chemical reactions. Due to the magnetic property of this nanocatalyst, it can be separated and collected from the reaction mixture by a magnet after the reaction is complete and reused.
