Total Synthesis of Goniomitine : Development of Aminal and α-Amino Radicals in the Synthesis of Nitrogen-Rich Natural Products

Creator:: Vellucci, Jessica K.
Abstract:: Aminal radical intermediates were generated by the method of radical translocation and reacted in C-C bond forming reactions with electronically deficient alkenes (Schiedler et al. Org. Lett. 2012, 14, 6092). Aminal radical intermediates can participate in inter- and intra-molecular reactions using both Bu3SnH and (TMS)₃SiH as hydride donors. Carbon–carbon bonds...

Total Synthesis of (±)-Goniomitine via Radical Translocation

Creator:: Vellucci, Jessica K. and Beaudry, Christopher M.
Abstract:: The aspidosperma alkaloid goniomitine was synthesized in six steps from 2-ethyl-δ-valerolactam. The convergent strategy features an Ullman coupling to assemble the required carbon atoms. A complexity-generating radical translocation reaction was used to build the indole architecture.

Substance Use and Imagery In Hip Hop, R&B, and Popular YouTube Music Videos

Creator:: Chac, Christina L., Stapleton, Angie, Seifert, Jessica, and Sakuma, Kari-Lyn K.
Abstract:: Background: There are over four billion YouTube views per day with “music” the most searched topic. Among US internet users, 8.3 million YouTube users are under 18 years old. Incorporation of substance use imagery in YouTube videos has a considerable potential influence on young viewing audience behavior. This study identifies...

Environmental drivers of the fine-scale distribution of a gelatinous zooplankton community across a mesoscale front

Creator:: Luo, Jessica Y., Grassian, Benjamin, Tang, Dorothy, Irisson, Jean-Olivier, Greer, Adam T., Guigand, Cedric M., McClatchie, Sam, and Cowen, Robert K.
Abstract:: Mesoscale fronts occur frequently in many coastal areas and often are sites of elevated productivity; however, knowledge of the fine-scale distribution of zooplankton at these fronts is lacking, particularly within the mid-trophic levels. Furthermore, small (<13 cm) gelatinous zooplankton are ubiquitous, but are under-studied, and their abundances underestimated due to...

Estimating animal population density using passive acoustics

Creator:: Marques, Tiago A., Thomas, Len, Martin, Stephen W., Mellinger, David K., Ward, Jessica A., Moretti, David J., Harris, Danielle, and Tyack, Peter L.
Abstract:: conservation and ecology. Currently, the most widely used methods for obtaining such estimates involve either sighting animals from transect lines or some form of capture-recapture on marked or uniquely identifiable individuals. However, many species are difficult to sight, and cannot be easily marked or recaptured. Some of these species produce...

Initiation of Genome Instability and Preneoplastic Processes through Loss of Fhit Expression

Creator:: Saldivar, Joshua C., Miuma, Satoshi, Bene, Jessica, Hosseini, Seyed Ali, Shibata, Hidetaka, Sun, Jin, Wheeler, Linda J., Mathews, Christopher K., and Huebner, Kay
Abstract:: Genomic instability drives tumorigenesis, but how it is initiated in sporadic neoplasias is unknown. In early preneoplasias, alterations at chromosome fragile sites arise due to DNA replication stress. A frequent, perhaps earliest, genetic alteration in preneoplasias is deletion within the fragile FRA3B/FHIT locus, leading to loss of Fhit protein expression....

Understanding ecohydrological connectivity in savannas: a system dynamics modelling approach

Creator:: Miller, Gretchen R., Cable, Jessica M., McDonald, Alyson K., Bond, Barbara, Franz, Trenton E., Wang, Lixin, Gou, Si, Tyler, Anna P., Zou, Chris B., and Scott, Russell L.
Abstract:: Ecohydrological connectivity is a system level property that results from the linkages in the networks of water transport through ecosystems, by which feedbacks and other emergent system behaviours may be generated. We created a system dynamics model that represents primary ecohydrological networks to examine how connectivity between ecosystem components impacts...

Increased harbor porpoise mortality in the Pacific Northwest, USA: understanding when higher levels may be normal

Creator:: Huggins, Jessica L., Raverty, Stephen A., Norman, Stephanie A., Calambokidis, John, Gaydos, Joseph K., Duffield, Deborah A., Lambourn, Dyanna M., Rice, James M., Hanson, Brad, Wilkinson, Kristin, Jeffries, Steven J., Norberg, Brent, and Barre, Lynne
Abstract:: In 2006, a marked increase in harbor porpoise Phocoena phocoena strandings were reported in the Pacific Northwest of the USA, resulting in the declaration of an unusual mortality event (UME) for Washington and Oregon to facilitate investigation into potential causes. The UME was in place during all of 2006 and...

The importance of lake-specific characteristics for water quality across the continental United States

Creator:: Read, Emily K., Patil, Vijay P., Oliver, Samantha K., Hetherington, Amy L., Brentrup, Jennifer A., Zwart, Jacob A., Winters, Kirsten, Corman, Jessica R., Nodine, Emily R., Woolway, Iestyn, Dugan, Hilary A., Jaimes, Aline, Santoso, Arianto, Hong, Grace S., Winslow, Luke A., Hanson, Paul C., and Weathers, Kathleen C.
Abstract:: Lake water quality is affected by local and regional drivers, including lake physical characteristics, hydrology, landscape position, land cover, land use, geology, and climate. Here, we demonstrate the utility of hypothesis testing within the landscape limnology framework using a random forest algorithm on a national-scale, spatially explicit data set, the...

Patterns and Variation in Benthic Biodiversity in a Large Marine Ecosystem

Creator:: Piacenza, Susan E., Barner, Allison K., Benkwitt, Cassandra E., Boersma, Kate S., Cerny-Chipman, Elizabeth B., Ingeman, Kurt E., Kindinger, Tye L., Lee, Jonathan D., Lindsley, Amy J., Reimer, Jessica N., Rowe, Jennifer C., Shen, Chenchen, Thompson, Kevin A., Thurman, Lindsey L., and Heppell, Selina S.
Abstract:: While there is a persistent inverse relationship between latitude and species diversity across many taxa and ecosystems, deviations from this norm offer an opportunity to understand the conditions that contribute to large-scale diversity patterns. Marine systems, in particular, provide such an opportunity, as marine diversity does not always follow a...
