Recombination-Based In Vivo Expression Technology Identifies Helicobacter Pylori Genes Important For Host Colonization, Andrea Castillo, Andrew J. Woodruff, Lynn E. Connolly, William E. Sause, Karen M. Ottemann

Biology Faculty Publications

Here we undertook to identify colonization and gastric disease-promoting factors of the human gastric pathogen Helicobacter pylori as genes that were induced in response to the stomach environment. Using recombination-based in vivo expression technology (RIVET), we identified six promoters induced in the host compared to laboratory conditions. Three of these promoters, designated Pivi10, Pivi66, and Pivi77, regulate genes that H. pylori may use to interact with other microbes or the host. Pivi10 likely regulates the mobA, mobB, and mobD genes, which have potential roles in horizontal gene transfer through plasmid mobilization. Pivi66 occurs in the cytotoxin-associated gene pathogenicity island, a …

Wildfire And Abrupt Ecosystem Disruption On California's Northern Channel Islands At The Allerod-Younger Dryas Boundary (13.0-12.9 Ka), Douglas J. Kennett, James P. Kennett, G. J. West, Jon M. Erlandson, J. R. Johnson, I. L. Hendy, A. West, B. J. Culleton, Terry L. Jones, Thomas W. Stafford, Jr.

Social Sciences

Sedimentary records from California's Northern Channel Islands and the adjacent Santa Barbara Basin (SBB) indicate intense regional biomass burning (wildfire) at the Ållerød–Younger Dryas boundary (~13.0–12.9 ka) (All age ranges in this paper are expressed in thousands of calendar years before present [ka]. Radiocarbon ages will be identified and clearly marked “¹⁴C years”.). Multiproxy records in SBB Ocean Drilling Project (ODP) Site 893 indicate that these wildfires coincided with the onset of regional cooling and an abrupt vegetational shift from closed montane forest to more open habitats. Abrupt ecosystem disruption is evident on the Northern Channel Islands at …

Dispersal Of The Hudson River Plume In The New York Bight: Synthesis Of Observational And Numerical Studies During Latte, Robert J. Chant, John Wilkin, Weifeng Zhang, Byoung-Ju Choi, Eli Hunter, Renato Castelao, Scott Glenn, Joe Jurisa, Oscar Schofield, Robert Houghton, Josh Kohut, Thomas K. Frazer, Mark A. Moline

Biological Sciences

Observations and modeling during the Lagrangian Transport and Transformation Experiment (LaTTE) characterized the variability of the Hudson River discharge and identified several freshwater transport pathways that lead to cross-shelf mixing of the Hudson plume. The plume’s variability is comprised of several different outflow configurations that are related to wind forcing, river discharge, and shelf circulation. The modes are characterized by coastal current formation and unsteady bulge recirculation. Coastal currents are favored during low-discharge conditions and downwelling winds, and represent a rapid downshelf transport pathway. Bulge formation is favored during high-discharge conditions and upwelling winds. The bulge is characterized by clockwise …

The Structure Of The Gospel Of Mark: Revisiting The Implications Of Repetition And Characterization, Gregory Michael

Master of Sacred Theology Thesis

The search for a distinctive and coherent structure to the Gospel of Mark has long been a challenge for scholarship. While denying redaction and narrative criticism's slavish adherence to their methodology, this thesis utilizes repetition and characterization to assess the matter of Markan structure. Key points of repetition addressed within the text are repetition of words and phrases, forms, and thematic items. The discussion of words and phrases highlight: θάλασσα, πάλιν, εἰς π̍εραν, ἐν τ̂ηὁσ̂ω, and Jewish leaders. The forms addressed are call narratives, exorcisms, and passion predictions. The thesis presents six key repeated thematic elements: geopolitical locations, the senses …

Sinorhizobium Meliloti, A Bacterium Lacking The Autoinducer-2 (Ai-2) Synthase, Responds To Ai-2 Supplied By Other Bacteria, C. S. Pereira, J. R. Mcauley, M. E. Taga, K. B. Xavier, Stephen T. Miller

Chemistry & Biochemistry Faculty Works

Many bacterial species respond to the quorum-sensing signal autoinducer-2 (AI-2) by regulating different niche-specific genes. Here, we show that Sinorhizobium meliloti, a plant symbiont lacking the gene for the AI-2 synthase, while not capable of producing AI-2 can nonetheless respond to AI-2 produced by other species. We demonstrate that S. meliloti has a periplasmic binding protein that binds AI-2. The crystal structure of this protein (here named SmlsrB) with its ligand reveals that it binds (2R,4S)-2-methyl-2,3,3,4-tetrahydroxytetrahydrofuran (R-THMF), the identical AI-2 isomer recognized by LsrB of Salmonella typhimurium. The gene encoding SmlsrB is in an operon with orthologues of the lsr …

Individuals And Populations: How Biology's Theory And Data Have Interfered With The Integration Of Development And Evolution, David S. Moore

Pitzer Faculty Publications and Research

Research programs in quantitative behavior genetics and evolutionary psychology have contributed to the widespread belief that some psychological characteristics can be “inherited” via genetic mechanisms. In fact, molecular and developmental biologists have concluded that while genetic factors contribute to the development of all of our traits, non-genetic factors always do too, and in ways that make them no less important than genetic factors. This insight demands a reworking of the Modern Evolutionary Synthesis, a theory that defined evolution as a process involving changes in the frequencies of genes in populations, and that envisioned no role for experiential factors now known …

The Effects Of Racial And Extracurricular Friendship Diversity On Achievement, Anil Nathan

Economics Department Working Papers

This paper finds the effect of having friends of a similar race and who are involved in similar activities. It explores data which allows a peer group to be defined openly through self nominations. Using a strategy that corrects for the endogeneity of peer effects by instrumenting using variables at the "grade within school" level, it is shown that friendship diversity can help whites increase achievement. Although not much significance was found with other races, most of the strategies pushed towards the direction of racial diversity aiding achievement. Regarding extracurricular activities, it is found that there is a benefit in …

An Analysis Of Current Healthcare Proposals: Obama And Mccain, Dan Terrell

Honors Projects in Economics

The healthcare system of the U.S. is broken. The next opportunity for overwhelming healthcare system reform will be when the next president takes office. This paper analyzes the 2008 presidential election candidates McCain and Obama healthcare proposals through a look at key players in the current healthcare system (government, pharmaceuticals, doctors, hospitals, and health insurance companies) and the affects of implementing such a plan. The presidential plans are presented side by side. Projected outcomes of the changes offered by Obama will be an increased role of the government and decreased power of the health insurance companies while increasing coverage. The …

Site Directed Mutagensis Of Bacteriophage Hk639 And Identification Of Its Integration Site, Madhuri Jonnalagadda

Masters Theses & Specialist Projects

Bacteriophages affect bacterial evolution, pathogenesis and global nutrient cycling. They are also the most numerous and diverse group of biological entities on the planet [1, 2, 3, 4, 5, 6]. Members of the Lambda phage family share a similar genetic organization and control early gene expression by suppressing transcription, a process known as antitermination. Transcription antitermination in Lambda is mediated by a phage-encoded protein whereas in lambdoid phage HK022, antitermination is mediated by a phage-encoded RNA molecules. Recent results suggest that another bacteriophage called HK639 also appears to use RNA-mediated antitermination. To characterize this newly identified phage we generated site …

Bourdieu And American Legal Education: How Law Schools Reproduce Social Stratification And Class Hierarchy, Lucille A. Jewel

Scholarly Works

The American legal profession has long been organized along hierarchical lines, and in many instances, status inequalities between attorneys are based on perceived differences in attorneys' educational credentials. Relying upon the theories of French sociologist Pierre Bourdieu, this essay will discuss how American legal educational institutions operate to reproduce the stratification within the legal profession and within society as a whole.

American law schools are not equalizing institutions that erase all class differences among students to create a profession that awards all of its members a monolithic class status. By allocating professional status based on a system of educational tiers, …

Efficacy Of Complementary And Alternative Medicine On Perceived Well-Being In Geriatric Long-Term Care Residents, Shannon L. Baer

Regis University Student Publications (comprehensive collection)

Non-conventional therapies have been termed and captured by the phrase Complementary and Alternative Medicine (CAM), since the establishment of The National Center for Complementary and Alternative Medicine (NCCAM), by the Federal Government in 1992. With the use of CAM on the rise in the baby boom population and the expectation that the number of nursing home residents is expected to double by 2020, it is imperative that healthcare providers gain more knowledge in effective means for treating the geriatric population holistically. The purpose of this study was to determine whether the implementation of a CAM intervention program in a sample …

What Is The Prevalence Of Overweight And Obesity And Its Relationship To Physical Activity In Children, Cameron Grove

Regis University Student Publications (comprehensive collection)

The purpose of this research project is to see if there is a relationship between the amount of physical activity a child gets during the week and their BMI. Previous studies have revealed an increase in the occurrence of childhood and adolescent overweight and obesity, and associations have been identified between physical activity, sedentary behaviors, dietary patterns and students perceptions of overweight and obesity (Tremblay, 2003). This research study was a casual comparative validation study due to the secondary data that was collected by the Colorado Department of Public Health and Environment. Overweight and obesity are determined by the BMI …

Evidence Of A Novel Rna Secondary Structure In The Coding Region Of Hiv-1 Pol Gene., Qi Wang, Ian Barr, Feng Guo, Christopher Lee

Natural Sciences and Mathematics | Faculty Scholarship

RNA secondary structures play several important roles in the human immunodeficiency virus (HIV) life cycle. To assess whether RNA secondary structure might affect the function of the HIV protease and reverse transcriptase genes, which are the main targets of anti-HIV drugs, we applied a series of different computational approaches to detect RNA secondary structures, including thermodynamic RNA folding predictions, synonymous variability analysis, and covariance analysis. Each method independently revealed strong evidence of a novel RNA secondary structure at the junction of the protease and reverse transcriptase genes, consisting of a 107-nucleotide region containing three stems, A, B, and C. First, …
