No Relationship Between Sequence Variation In Protein Coding Regions Of The Tas1r3 Gene And Saccharin Preference In Rats., Clinton Chapman, Ke Lu, Amanda Mcdaniel, Michael Tordoff, Li Xia, Gary Beauchamp, Nancy Dess, Dennis Vanderweele, Liquan Huang, Hong Wang, Danielle Reed

Nearly all mammalian species like sweet-tasting foods and drinks, but there are differences in the degree of 'sweet tooth' both between species and among individuals of the same species. Some individual differences can be explained by genetic variability. Polymorphisms in a sweet taste receptor (Tas1r3) account for a large fraction of the differences in consumption of sweet solutions among inbred mouse strains. We wondered whether mice and rats share the same Tas1r3 alleles, and whether this gene might explain the large difference in saccharin preference among rats. We conducted three experiments to test this. We examined DNA sequence differences in …


What Communities Should Do Pre-Event To Support Public Health Post-Event Assessments, Surveillance And Monitoring, Thomas Lyons Carr Iii Feb 2005

What Communities Should Do Pre-Event To Support Public Health Post-Event Assessments, Surveillance And Monitoring, Thomas Lyons Carr Iii

Thomas Lyons (Thom) Carr III Appl.Sc., CEM

[Abstract written March 2008, TLC] Under worst-case planning assumptions used by some major metropolitan areas, a Neighbor-to-Neighbor self-help program model is the primary link between citizens and the professional response personnel of the responsible government agencies.

In the Neighbor-to-Neighbor self-help program model or a Community Emergency Management Plan (CEMP) calls on the citizens in neighborhoods to identify and establish cluster emergency preparedness committees, Cluster Emergency Coordination Centers (CECC) and Community Emergency Response Teams (CERT). Missing from these plans or what is not articulated is how constant Public Health Post-Event Surveillance, Monitoring and Assessments will be done. Given the worst-case planning …


Classical Conditioning Of Red-Backed Salamanders, Plethodon Cinereus, Scott Kight Dec 2004

Classical Conditioning Of Red-Backed Salamanders, Plethodon Cinereus, Scott Kight

Scott Kight


We examined associative learning as it relates to the sensory ecology of the red-backed salamander, Plethodon cinereus, using a classical conditioning design to evaluate the response of salamanders to different kinds of stimuli.  Conditioned stimuli (CS) reflected visual, chemosensory, and mechanosensory modalities of P. cinereus, with brief exposures to (I) white light, (II) acetic acid fumes, (III) low-frequency sound, and (IV) low-frequency vibration.  In all experiments, a gentle mechanical stimulation of the tail served as the unconditioned stimulus (US), which consistently elicited movement of the head or body as the unconditioned response (UR).  For two days, the US …
