Diversity of insects associated with two common plants in the Brazilian Cerrado: Responses of two guilds of herbivores to bottom-up and top-down forces

Vitamin K The Trophic Cascade Theory has been used to explain the organization of herbivorous insect communities in tropical ecosystems.In addition, the insect community associated with a species of plant can also be determined by the geographical distribution and taxonomic isolation of the plant.In this study, the following predictions about the n

Dysregulation of Rac or Rho elicits death of motor neurons and activation of these GTPases is altered in the G93A mutant hSOD1 mouse model of amyotrophic lateral sclerosis

Rho GTPases play a central role in neuronal survival; however, the antagonistic relationship between Rac and Rho in the Sandal regulation of motor neuron survival remains poorly defined.In the current study, we demonstrate that treatment with NSC23766, a selective inhibitor of the Rac-specific guanine nucleotide exchange factors, Tiam1 and Trio, is
