GluA3-deficiency in mice is associated with increased social and aggressive behavior and elevated dopamine in striatum.

Glutamate signaling has been implicated in the regulation of social behavior. AMPA-glutamate receptors are assembled from four subunits (GluA1-4) of mainly GluA1/2 and GluA2/3 tetramers that form ion channels of distinct functional properties. Mice lacking GluA1 showed a reduced anxiety and male aggression.

PGE2 EP1 receptor exacerbated neurotoxicity in a mouse model of cerebral ischemia and Alzheimer's disease.

Stroke and Alzheimer's disease (AD) are major age-related neurodegenerative diseases that may worsen the prognosis of each other. Our study was designed to delineate the prostaglandin E(2) EP1 receptor role in AD and in the setting of cerebral ischemia. Genetic deletion of the prostaglandin EP1 receptor significantly attenuated the more severe neuronal damage (38.

Naming migraine and those who have it.

Medical language has implications for both public perception of and institutional responses to illness. A consensus panel of physicians, academics, advocates, and patients with diverse experiences and knowledge about migraine considered 3 questions: (1) What is migraine: an illness, disease, syndrome, condition, disorder, or susceptibility? (2) What ought we call someone with migraine? (3) What should we not call someone with migraine? Although consensus was not reached, the responses were summarized and analyzed quantitatively and qualitatively. Panelists participated in writing and editing the paper.

Plant toxicity testing to derive ecological soil screening levels for cobalt and nickel.

Phytotoxicity tests were performed to set ecological soil screening levels for cobalt (Co) and nickel (Ni) following the American Society for Testing and Materials international E1963-98 Standard Guide for Conducting Terrestrial Plant Toxicity Tests. Two soils (a modified artificial soil mixed with 5% organic matter, pH 5.01, and a native riverine sandy soil with 0.

Using landscape ecology to focus ecological risk assessment and guide risk management decision-making.

Ecological risk assessment (EcoRA) generally suffers from limited application of ecological knowledge in the definition and characterization of real-world sites. Not surprisingly, most remediation decisions, which follow, have little or no relationship to the valued ecological resources of the site or the broader region. The practice has evolved to favor engineering-based mitigation strategies, which eliminate excess chemical concentrations at sites, or otherwise break exposure pathways, but which may not be ecologically beneficial.
