A Novel Positive Allosteric Modulator Of Glun1/3 Nmda Receptors, Samuel A. Galindo

Graduate Student Theses, Dissertations, & Professional Papers

The GluN3-containing (GluN1/3) N-methyl-D-aspartate (NMDA) receptors are glycine activated ligand-gated ion channels that are members of the family of excitatory ionotropic glutamate receptors. Compared to the glycine/glutamate-activated GluN2- containing NMDA receptors (GluN1/2), which have been extensively studied, the GluN1/3 receptors are poorly understood, but are implicated in neuronal processes related to synaptic maturation and plasticity. GluN1/3 receptors are also implicated in a variety of neurological diseases. In addition to their poor understanding, we lack proper pharmacological tools for the study and modulation of these GluN1/3 receptors. In this study, we evaluate the activity and mechanism of action for AIMS-129 as …

Determining The Susceptibility Status Of Red Sunflower Seed Weevil, Smicronyx Fulvus (Coleoptera: Curculionidae) To Pyrethroid Insecticides, Aaron Lee Hargens

Electronic Theses and Dissertations

Although sunflowers are native to North America, the early breeding efforts to improve sunflowers occurred outside of the continent. These hybrids were reintroduced to North America around 1875. In the early 1900’s, efforts to increase oil content were achieved by selective breeding of the reintroduced hybrids. Although this resulted in the development of improved sunflowers, many of the traits that conferred resistance to native insect pests were lost. One insect pest, the red sunflower seed weevil was noted as having caused sunflower production to rapidly decline and eventually end in Illinois and Missouri.
