+-May 7, 2014 - Using Analogs of the Natural Product Curcumin to Combat Prostate Cancer Cells

Marco Bisoffi, Ph.D. Marco Bisoffi, Ph.D
Associate Professor of Biological Sciences, Biochemistry and Molecular Biology
Chapman University

Chapman University, Argyros Forum Student Ballroom, 119A
Noon to 1 p.m.


Title: Using Analogs of the Natural Product Curcumin to Combat Prostate Cancer Cells

Summary

Prostate cancer cells rely on several molecular pathways for their growth and survival. These pathways have been identified as points of “oncogenic addiction.” One such pathway is androgen signaling through the androgen receptor triggered by testosterone. Inhibition of this pathway has been shown to efficiently inhibit prostate cancer cell growth. This presentation will explore the possibility of using analogs of the natural product curcumin (from turmeric) to inhibit androgen signaling and prostate cancer. The potential for the (pre)clinical development of novel curcuminoid compounds will be discussed.

+-April 9, 2014 - The Heart’s Content: Positive Psychological Well-Being and Cardiovascular Health

Julia Boehm, Ph.D. Julie Boehm, Ph.D
Assistant Professor of Psychology
Chapman University

Chapman University, Argyros Forum Student Ballroom, 119A
Noon to 1 p.m.


Title: The Heart’s Content: Positive Psychological Well-Being and Cardiovascular Health

Summary

Associations between psychological health and physical health have long been recognized. However, most research to date has investigated the association between poor psychological functioning (e.g., depression, anxiety, and hostility) and physical health. Increasing research suggests that positive psychological well-being (e.g., optimism, purpose in life, and happiness) may also be related to health independently of the effects of psychological ill-being. This talk reviews the evidence linking positive psychological well-being with cardiovascular disease, which is a leading cause of death worldwide. The behavioral and biological pathways underlying the association between positive psychological well-being and cardiovascular disease are also explored. If positive psychological well-being can be established as an antecedent of cardiovascular disease, as well as an antecedent of underlying behavioral and biological processes, then it may provide a novel approach to fostering health promotion.

+-Mar. 19, 2014 - Metabolites, Germs and People: Human-associated Microbial Communities in Health and Disease

Katrine Whiteson, Ph.D. Katrine Whiteson, Ph.D
Adjunct Assistant Research Professor
Chapman University

Chapman University, Argyros Forum Student Ballroom, 119B
Noon to 1 p.m.


Title: Metabolites, Germs and People: Human-associated Microbial Communities in Health and Disease

Summary

I am interested in understanding how individual and persistent human-associated microbial and viral communities affect health. Infection with a bacterial pathogen, vaccination, immune development and even taking a Tylenol does not occur in a vacuum. Dynamic microbial and viral communities constantly inhabit our bodies, encoding the majority of the unique genes that alter these processes. I use metagenomics, metabolomics, microbiology and ecological statistics to answer questions about how microbes and viruses affect human health. The hypothesis underlying my work is that human-associated microbial communities are powerful indicators of health and disease. I will introduce recent discoveries about human-associated microbial communities enabled by access to high-throughput sequencing in the last 5-10 years, and present three research projects examining the composition and activity of microbial communities using metagenomic sequence data from 1) healthy humans, 2) malnourished children who develop a devastating facial gangrene with no clear infectious cause, and 3) Cystic Fibrosis patients.

+-Mar. 5, 2014 - Imaging the Molecular Dynamics of Focal Adhesion Proteins in Live Cells

Michelle Digman, Ph.D. Michelle Digman, Ph.D

Assistant Professor, Department of Biomedical Engineering
University of California Irvine

Chapman University, Argyros Forum 119B
Noon to 1 p.m.


Title: Imaging the Molecular Dynamics of Focal Adhesion Proteins in Live Cells

Summary

Molecular interactions and mobility can be studied in live cells as well as the map the interactions of key focal adhesion proteins in real time and space. Confocal microscopy can be used to map these interactions in living biological systems. We have developed a tool used based on the fluorescence correlation spectroscopy method to measure protein diffusion, kinetics and quantitatively calculate concentrations. To gain information in space and time at broader scale with fast temporal resolution, raster image correlation spectroscopy (RICS) is the best method for this type of analysis. RICS significantly enhances the capability to measure many points while obtaining information at a larger scale. Binding rates at fix positions such as protein scaffolds can be accurately calculated as well as binding interactions with other partners can be implemented with dual color labeling. In this lecture we will discuss the principle of the RICS method, mathematical framework and applications. In addition we will demonstrate how data acquired from RICS can be used to calculate molecular brightness to determine protein aggregation sizes. The Number and Brightness (N&B) method uses a simple mathematical calculation based on variance of intensity from the fluctuating species to calculate the brightness (B) and the ratio of the total intensity to brightness to determine the number of molecules (N). The advantage of RICS is that it can be performed on most commercial microscopes available in research core facilities or individual labs. Overall the RICS and N&B methods are powerful tools in determining molecular dynamics in live cellular systems and can easily be implemented in any microscopy setup.

+-Feb. 12, 2014 - Developing a Universal Enrichment Broth for Foodborne Bacterial Pathogens

Kirsten Hirneisen, Ph.D. Kirsten Hirneisen, Ph.D.
Commissioner's Fellow
US Food and Drug Administration

William Lyons Conference Center, Arygros Forum 209A
Noon to 1 p.m.

Title: Developing a Universal Enrichment Broth for Foodborne Bacterial Pathogens

Summary
Foodborne bacterial pathogens have been the cause of high profile outbreaks in the last several years that have resulted in serious illnesses, hospitalizations and deaths. For successful prevention of foodborne pathogens, rapid and reliable detection methods need to be developed for testing of foods. Depending on the food matrix and target pathogen, different pre-enrichment broths are used when following the FDA’s Bacteriological Analytical Manual (BAM) directions for sample preparation prior to conventional culturing for the detection of foodborne bacterial pathogens. In addition to the preparation of multiple pre-enrichment broths being labor intensive, time consuming and costly, the use for multiple enrichment broths is a major roadblock when trying to develop methods designed for multi-target pathogen detection such as multiplex qPCR. This presentation will focus on efforts to develop a universal enrichment broth to ultimately allow for multi-target pathogen detection in food matrices.

+-Dec. 4, 2013 - Microbial Diversity, Ecosystem Functioning, and Global Change

Professor, Dept. of Ecology and Evolutionary Biology
University of California, Irvine

Chapman University, Argyros Forum Student Ballroom, AF 119B
Noon to 1 p.m.

Title: Microbial diversity, ecosystem functioning, and global change

Abstract
Microorganisms drive many processes in ecosystems on which humans depend. Recent research demonstrates that the variety of microbes affect the rate of processes such as decomposition and CO2 flux to the atmosphere as well as how an ecosystem responds to environmental change. I will discuss the challenges of incorporating microbes into predictions of ecosystem functioning in the face of expected global changes.

+-Nov. 13, 2013 - Controls of Greenhouse Gas Production

Cassandra Medvedeff, Ph.D. Cassandra Medvedeff, Ph.D.
Post-doctoral Research Associate
Chapman University

Chapman University, Argyros Forum Student Ballroom, AF 119B
Noon to 1 p.m.

Title: Controls of Greenhouse Gas Production: Studies from the Florida Everglades to Minnesota Peatlands

Abstract

Wetlands are key ecosystems which regulate the global carbon cycle through both storing and emitting large quantities of carbon.  These ecosystems are the largest natural source of the greenhouse gas methane; however production of this gas varies considerably among wetland types.  Thus, understanding controls of methane production in wetland ecosystems is crucial.  This presentation will focus on different regulators of CH4 production in subtropical and boreal wetlands in the context of global climate change scenarios.

Francis Edward Su, Ph.D.
Francis Edward Su, Ph.D.
Professor of Mathematics
Harvey Mudd College

Chapman University, Argyros Forum Student Ballroom, AF 119A
Noon to 1 p.m.

Abstract
When does a majority exist? How does the geometry of the political spectrum influence the outcome? What does mathematics have to say about how people behave? When mathematical objects have a social interpretation, the associated results have social applications.  We will show how math can be used to model people's preferences and classical results about convex sets can be used in the analysis of voting in "agreeable" societies.  This talk also features research with undergraduates.

+-Sept. 11, 2013 - The Stress Process Among Foreign-born Latino Groups

Dr. Georgiana Bostean

Argyros Forum Student Ballroom, AF 119A
Noon to 1 p.m.

Title:  The Stress Process Among Foreign-born Latino Groups: Examining the Roles of Migration-related Stress, Family Conflict, and Family Cohesion in Psychological Distress

Abstract

Latino immigrants may face unique stressors, such as family conflict and other migration-related stress, which have deleterious mental health consequences. Strong family cohesion among Latinos may buffer the negative effects of such stressors. This study draws on the stress process model to examine the roles of migration-related stress (e.g., felt guilty for leaving family in country of origin; find it hard interacting with others because of difficulties with the English language) and family conflict in psychological distress, and whether family cohesion mediates or moderates the association between psychological distress and migration-related stress. We examine foreign-born Latinos from the National Latino and Asian American Survey (n=1,532), computing zero-truncated Poisson regressions from which we calculate predicted levels of psychological distress. Results show that, while migration stress is independently associated with higher distress, there is an interaction with family cohesion such that increased migration stress is associated with higher distress only among those with high family cohesion. Moreover, those with the highest family conflict have much higher distress levels than those with the lowest conflict (approximately 20 versus 11, respectively). Findings speak to the harmful mental health effects of migration-related stress and family conflict, and the role of family relationships in buffering foreign-born Latinos’ mental health outcomes. These results may inform interventions aimed at improving mental health among foreign-born Latinos.

U.S. Salinity Lab

Argyros Forum 119A, Student Union
12 - 1 p.m. 

Manure-contaminated soil and water resources have frequently been associated with water-borne and food-borne disease outbreaks. The talk will discuss factors influencing surface water and food contamination in the Santa Ana River (SAR) watershed, which contain a large number of concentrated animal operations (CAFOs). CAFO wastewater is reported to influence the quality of the SAR, which empties into the Pacific Ocean at Huntington Beach. Runoff and irrigation water that contained pathogens will also contaminate soils and fresh produce.  The contamination of fresh produce by pathogens such as E. coli O157:H7 is a serious food-safety concern that is currently being worked on.

+-Nov. 20, 2012 - New Findings Related to Aerosol-Cloud-Precipitation Interactions

Armin Sorooshian 

Armin Sorooshian
Assistant Professor
Department of Chemical and Environmental Engineering
Department of Atmospheric Sciences
The University of Arizona

Argyros Forum 119A, Student Union
12 - 1 p.m. 

Atmospheric aerosol particles range in size from a few nanometers up to several micrometers in diameter and can be composed of tens of thousands of species. Although they are so small, they have very important effects. For example, they directly interact with solar radiation and act as cloud condensation nuclei, which are the seeds of clouds. Consequently, particles influence the earth’s radiation balance, atmospheric visibility, the hydrologic cycle, and the biogeochemical cycling and transport of nutrients and contaminants. Particles also negatively impact public health and welfare. This talk will report on recent measurements focused on aerosol-water interactions in both maritime and continental atmospheres, with a focus on how aerosol perturbations modify cloud properties and precipitation generation. Results will be presented from surface, aircraft, and satellite remote sensing studies.

About the Speaker:
Armin is an Assistant Professor of Chemical and Environmental Engineering at the University of Arizona with a joint appointment in Atmospheric Sciences. His research focuses on the effect of aerosol particles on environmental and climate change, public health, and the hydrologic cycle.

+-Aug. 29, 2012 - Birth and Death of Oceanic Crust: Ocean Spreading Centers and Subduction Zones

Prof. Satish Singh

Satish C. Singh

Argyros Forum 119A, Student Union
12 - 1 p.m. 

Over 70% of the Earth’s crust is created in the middle of oceans along %7e55000 km of volcanic chains, called mid-ocean ridges or ocean spreading centers, the birth place of oceanic crust. At ocean spreading centers the plate separates causing the mantle to move upwards, reducing the pressure and causing the melting of the mantle. Since the melt is lighter than the surrounding mantle material, it moves upwards towards the surface of the Earth. Part of the melt is erupted on the seafloor as lava, which cools very rapidly forming a cap of solid extrusive layer. As there is a significant amount of water present at mid-ocean ridges, the water circulates deep in the crust. Therefore, a significant amount of melt stays in the middle of the crust and erupts along thin dikes. Below the dikes, the melt could reside for a long period, forming a steady state melt lens, called axial melt lens or axial magma chamber. The magma cools and crystallises in this melt lens, forming the lower crust. The water can circulate down to the melt lens, brings rich minerals, and forms black smokers on the seafloor. The water rich in minerals and the heat (up to 350° C) provide food for many deep-sea habitat (such as shrimps, clams etc.) and millions of other form of lives. It has been suggested that the life on earth started at ocean spreading centers around these smokers.

As plate moves away from the spreading centers, it cools and forms a thick lithosphere. This cold oceanic lithosphere subducts (or disappears) beneath the continents enveloping it by 60 000 km long up to 11 km deep trench system. As the oceanic plate subducts, it get locked for a long time (10-1000 years) by the overriding plate, producing large earthquakes. These Earthquakes initiate at 20-30 km depth but arrive on the seafloor uplifting the 4-5 km water column producing devastating tsunamis. 

The birth of the oceanic crust at ocean spreading center provides lives whereas during its destruction at the subduction zone, it takes lives, and cycle of the creation and destruction continues for millions of years.
