In this study, we investigated the locomotion behavior changes at different developmental stages in Caenorhabditis elegans exposed to metals for 4h. No obvious differences could be observed in young adults exposed to examined metals, and only exposure to 100 microM of examined metals could significantly decrease the locomotion behaviors of L4 larvae.

Caenorhabditis elegans is as an ideal model system for the study of mechanisms underlying learning and memory. In the present study, we employed C. elegans assay system of thermotaxis memory to investigate the possible role of serotonin neurotransmitter in memory control. Our data showed that both mutations of tph-1, bas-1, and cat-4 genes, required for(More)
With the rapid development of national economy, modern industry develops towards a nonlinear, large-scale and totalization direction, resulting in an increasing need for fast, efficient and robust optimization algorithms. The appearance of the intelligent computing methods brings hope to the solutions of these complex issues. This paper introduces the(More)
