Stem Cell Targeting and Antineoplastic Effects in Ovarian Cancer Cells
Ovarian cancer is the deadliest of the gynecologic malignancies. Despite
significant advances in chemotherapy, the cure rate for advanced stage
ovarian cancer has not changed significantly over the last 20 to 30 years.
The search for a more effective and less toxic therapy for ovarian cancer
is ongoing. Circulating bone marrow-derived stem cells are recruited from
the blood into peripheral solid organs during times of stress or injury.
A similar environment is found in the hypoxic microenvironment of solid
tumors, including those originating from the ovary. We hypothesize that
stem cells from bone marrow will preferentially migrate to and engraft
in metastatic ovarian tumors. Our first specific aim is to assess effect
of ovarian cancer cells on stem cell migration. We will measure migration
of human stem cells in response to chemotactic factors secreted by ovarian
cancer cells. Student associates will assess stem cell migration following
exposure to conditioned media derived from ovarian cancer cells. They
will also examine stem cell migration in multicellular tumor spheroids.
Our second specific aim will evaluate apoptosis in ovarian cancer cell
lines following co-culture with human bone marrow stem cells. Student
associates will assess late apoptotic events using morphologic characteristics
of cancer cells and early apoptotic events by evaluating changes in plasma
membrane asymmetry using Annexin V. Data from these experiments will generate
preliminary data for Illinois Department of Public Health and NIH proposals.

Exploratory Research in Directing the Growth of Metal Nanoparticles
The goal of the proposed research is to examine influences of various
surface-active compounds on the morphology and properties of colloidal
noble metals, seeking methods to produce monodispersed, nonspherical colloidal
particles. The localized surface plasmons of non-spherical (lower-symmetry)
colloidal metal particles can extinguish more light with different energies
than plasmons of spherical particles; therefore, synthetic methods for
the nonspherical particles are of interest to scientists. Conditions that
will be varied during particle syntheses include composition and concentration
of metal precursors and surface active agents. The particles themselves
will be characterized by UV-visible spectroscopy, powder X-ray diffraction,
and scanning and transmission electron microscopy. This research will
be performed with undergraduate co-workers in all of its stages.

Presenting a Data Analysis Software Environment to the Smithsonian
Tropical Rainforest Institute
In 2006-2007, the Department of Computer Science and Information Systems
is offering a new course called Capstone Project. This course requires
students to work on a significant software team project. For the initial
offering of this course, we are working on a project with the Smithsonian
Tropical Rainforest Institute (STRI). We are building a database and data
environment for storing, managing, editing, and reporting the diameter
of trees, a count of species in a given area of forest, and a comprehensive
list of species. This work is based upon database design work performed
by Bradley University students in the 2004-2005 academic year. The initial
focus is on the rainforest in Panama, but the database and software needs
to support data and users from tropical rainforests in other countries,
including Ecuador, Cameroon, and the Congo. We propose that the class
present their work at a meeting with the client (STRI), the client’s
major donor, and world renowned botanists from other institutions including
Harvard University and the University of North Carolina, Chapel Hill.

Attitudes of People Using Social Services
in the Peoria Area
This is research project being conducted by students in a
social work research class. The survey is a replication of a survey conducted
in the New York City area by the Community Service Society (CSS). CSS
has granted Bradley permission to replicate their survey and have approved
all modifications. The survey has been distributed to six social service
agencies in the Peoria area. The purpose is to gain an understanding of
the attitudes of these people toward various political issues and service
programs in the area. Results will be compared to the New York findings.

Modulation of Macrophage Functional Capacities
This proposal is to provide an environment to engage students in research,
offering them the broadest possible choices and the opportunity to develop
a novel direction in research, thus enhancing their experience above and
beyond that of being assigned a role in a project with limited scope.
This environment will be built around a research program to discover how
xenobiotics and endogenous factors affect macrophage function. Because
macrophages are pivotal members of both innate and adaptive immunity,
alterations in macrophage functions would have profound consequences on
body defenses. Xenobiotics under investigation are cigarette smoke condensates,
hydrolysis products of glucosinolates, and synthetic ?-opioid receptor
agonists. While all the lines of studies have progressed to varying degrees,
they all involve assessing the macrophage functions affected by the agents,
identifying the stimuli that normally lead to those functions, and determining
the signaling process undermined by the agents. In the future, we hope
to devise mechanisms to reverse these effects. An endogenous factor under
investigation is the transcription factor STAT4. Our aim is to determine
STAT4 function in human macrophages, and to develop a detail understanding
of how STAT4 production and activation is regulated. One of these lines
of research has already led to two publications with seven Bradley undergraduate
co-authors, and an additional line is poised to bear publication fruit,
again with Bradley undergraduate co-authors.

Identification of Factors Influencing Hybrid Success in Gentians
Two congeneric plant species, Gentiana puberulenta and G.
flavida, are spontaneously hybridizing in a restored prairie near Kickapoo,
Illinois. These two species are reported to be adapted to different habitats
but, based on corolla color differences, approximately half of the gentians
in the prairie restoration are hybrids. The goal of the proposed investigation
is to determine if comparatively high fitness is contributing to hybrid
success at the restored prairie. We will genotype and quantify corolla
color of the gentians in seven 2 x 2 meter plots to definitively assign
plants as G. puberulenta, G. flavida or as hybrids. Fitness will be estimated
with flower number and water-use traits.

The Body Project
Research indicates that one in five college-age women suffers
from an eating disorder (NEDA 2006). Countless other young women and men
suffer from body image disturbances that have a negative impact on their
health, development and academic performance. While many universities
and colleges have programs to educate the campus community on these issues,
Bradley does not have such a program. With the aim of filling this gap,
the Women’s Studies Program and the Center for Wellness are in the
process of developing The Body Project, a multifaceted and collaborative
research and service project involving academic faculty, wellness staff
and students. The project aims to investigate the scope and nature of
body image disturbances among Bradley students, educate the campus community
on issues related to body image and eating disorders, improve access to
existing resources and expand campus resources and programs in this area.
To this end, we are seeking a seed grant under Bradley’s Special
Emphasis Initiative. Once we have implemented the Project, we will seek
external funding to cover on-going expenses.

Cloning of the Mercury-Resistance merA gene
Environmental mercury exposure is an international concern
because of its direct toxicological effects (e.g., neurotoxin, mutagen)
on humans and wildlife. The primary focus of my research over the past
eight plus years (3 at Colby College, Waterville, Maine and 5 at Bradley
University) has been to characterize mercury-resistant bacteria from environmental
sources, primarily focusing on hatchery-reared salmonids (lake, rainbow
and brook trout). The characterization has entailed the isolation of mercury-resistant
bacteria from these environmental sources, determination of species identity
using molecular techniques, and characterization of antibiotic-resistant
traits in these bacteria. There is a strong correlation between mercury-resistance
and antibiotic-resistance (Summers et al., 1993; Wireman et al., 1997;
Stepanauskas et al., 2006) and the different bacteria that have been identified
to date demonstrate maximal antibiotic-resistance to up to 15 of 22 antibiotics
tested. I plan to continue to work on characterizing the genetic link
between mercury- and antibiotic-resistance in these bacteria.

Behavioral Psychopharmacology
This proposal aims to accelerate student engagement in the
newly established Drug Abuse Research Laboratory in two important ways:
First, among students enrolled in Independent Research, we propose to
evaluate the ability of a putative drug addiction pharmacotherapy to influence
the reinstatement of cocaine-seeking behavior in a rodent model of cocaine
craving and relapse. Second, we wish to establish the parameters of a
novel drug delivery device in an animal model of Attention-Deficit/Hyperactivity
Disorder for students participating in summer research. The results of
these studies will be presented by student participants at regional conferences
and will be published in peer-reviewed journals.

Minorities in Computer Science Education Outreach Project
With the number of women and minorities in the field of computer science
falling dramatically in the last few years, the field faces a crisis.
The Minorities in Computer Science Education Outreach Project is a service
program being created for the Spring 2007 semester by four female students
studying computer science as either a major or minor. The learning goals
for this project are to introduce Bradley students to the formal method
of outcome based learning, to provide a forum for Bradley students to
explore the issue of women and minorities in education, and to expose
PK12 students, particularly females and minorities, to the field and the
job opportunities within it. The visit program will be modeled after several
other school programs, including Carnegie-Mellon University’s CS
Road Show program [CMU] and the University of Indiana’s Just Be
program [Indiana] presented by undergraduate and graduate women studying
computer science. The project will target local Peoria community schools.

Examining oligomerization of gp96 in vitro and in vivo
Gp96 is a chaperone protein that binds peptides and proteins in vivo.
We have shown previously that in vitro heat treatment causes gp96 to assemble
into several distinct homooligomeric species, a process that is inhibited
by ATP. We propose here to explore whether higher order oligomers can
be observed in vivo under a variety of conditions, including ATP depletion.
We also plan to develop methods for preparative separation of the gp96
oligomers of different masses so that their molecular weights/stoichiometries
can be determined and so that any differences in their properties can
be explored. Finally, we plan to design and prepare site-directed mutants
of gp96 that will allow us to begin define the structural origins of oligomerization.

Measurement of individual differences in attentional control among
preschoolers
The purpose of the proposed research is to create a measurement of individual
differences in attentional control among preschoolers. Student research
assistants will create experimental stimuli that require children to suppress
a practiced response over a series of trials. Children’s inhibitory
control—their suppression of the interfering response—will
be related to the extent they control and monitor their attention to the
experimental stimuli. Student research assistants will administer the
test to preschoolers, code and analyze the data, and participate in the
presentation of the data in professional outlets.

Self-Assembly of Metallic Nanowires on Si Surfaces
We propose a multifaceted project involving studies of the formation,
structure, thermal decay, and the electrical properties of self-assembling
metallic nanowires on various Si substrates. We will bring to bear on
this important topic of scientific and technological interest the extensive
surface measurement capabilities in the Bradley physics department. This
project will have a very large educational impact on several undergraduate
students in our department by providing them with the opportunity to engage
in all aspects of scientific research, including operating and maintaining
sophisticated scientific instrumentation, gathering data, disseminating
the research results via presentations at national meetings and contribution
to the writing of publications, and also through contributing to the grant-writing
process for the purpose of securing extramural funding. These skills are
invaluable for undergraduates to acquire, and will greatly benefit our
students as they move beyond Bradley into their scientific careers.

Are Scientific Research Experiences for Teacher
Education Majors an Effective Pedagogical Tool?
At Bradley University, education majors are offered a fairly
unique option, Science 101, to partially fulfill program requirements
in science. This course, developed through the collaborative work of faculty
in three colleges, allows students to learn science through inquiry-based,
cross-disciplinary, thematic instruction that models best practices in
science pedagogy. This project will assess the possibility of an additional
inquiry opportunity for education majors. In the past few semesters, some
education majors have also participated in a special section of BIO 280.
These students have had a research immersion experience where they participate
in actual, on-going research projects. Anecdotal evidence indicates positive
benefits to both education and science majors. This course offering has
been developed on-the-fly and there has been no formal assessment plan.We
propose to assess the impact on students of being involved in research
experiences involving majors and non-majors as we develop a more permanent
structure that can (a) serve as a one-credit hour lab course that would
meet teaching certification standards, and (b) be employed by a wider
group of science and engineering faculty members. To reach this end, we
propose to (1) develop through the collaborative efforts of a cross-disciplinary
Working Group, Research Immersion for Educators, a 1-credit hour laboratory
science course; (2) assess through a student/faculty collaborative research
project, whether this course is furthering our objective of preparing
a new cadre of science education professionals, and, (3) (if warranted)
prepare a course proposal and accompanying major change proposal for submission
to C&R.

Dissemination/Presentation Phase of A Research Study
A Presentation of Applications of Cognitive Reading Strategies in High
School Classrooms in Conjunction with a Research Study into the Reading
Behaviors of Adolescents. In spring 2006, three secondary education majors
participated as junior scientists in a study of the effectiveness of using
a language scanning device, the Readingpen?, by junior high and high school
students who are characterized as struggling readers. Funded by Wiscom
Technologies and Bradley University Center for Research and Service, this
study required weekly collaborations between each junior scientist and
two students in three Central Illinois schools. Data were collected regarding
student perceptions of their reading behaviors as well as the frequency
of accessing words and subject terminology using the Readingpen. Pre-
and posttests were given to document changes in reading fluency. Subsequently,
all data was coded by a graduate assistant and analyzed jointly by the
primary investigator and all junior scientists. Together with the PI,
they will present a session on strategic reading at the annual
conference of the Illinois Reading Council in March 2007. An article to
a distinguished journal, The Journal of Adolescent and Adult Literacy,
is in preparation with all members of the research team as co-authors.

Waterless Cookware Comparison Study
This study will be conducted by Family and Consumer Sciences’
Students in collaboration with Dr. Nina Collins and the Healthy Gourmet
Cookware Company. Healthy Gourmet specializes in high-end kitchen supplies.
Our purpose is to determine the effects of cooking techniques of vegetables
and meat in Healthy Gourmet Cookware compared with another high-end gourmet
cookware (Calphalon Cookware) and the resulting nutrient retention, color
retention, cooking time, and consumer taste acceptability.

Cookware trends among engaged couples attending
Bradley University
This study will be conducted by Family and Consumer Sciences’
Students in collaboration with Healthy Gourmet Cookware. Healthy Gourmet
specializes in high-end kitchen supplies. Our purpose is to determine
what factors influence consumer choice of cookware, particularly engaged-to-be
married, college students. We plan to conduct a focus group with engaged
couples at Bradley University in February 2007. The focus group will include
a discussion, interviews, and a cooking demonstration with Healthy Gourmet
cookware. Based upon a literature review on trends in consumer cookware
choice we developed questions and research strategy to use with focus
groups. This information will be disseminated to Healthy Gourmet to aid
them in their marketing efforts.

Fashion and Diabetes
The Department Chair of Family and Consumer Sciences was asked
by an alumnae, Nicole Herron, RD, LDN, CDE who works for Smith Medicals
as a Diabetes Sales Specialist to design diabetic pumps for children and
youth who are required to wear an Insulin Pump. Six Family and Consumer
Sciences Students and three FCS faculty will meet with Ms. Herron and
these children and youth on December 4, 2006. After this meeting the Bradley
students will design pump pack kits for these children and youth. The
exact content of the kit will be determined as the design for the pump
pack is developed. The goal is for each diabetic child to have at least
one specially designed pump pack for them and a kit to assist them or
a family member is making other pump packs for their life style. A second
event will be held in late March where the diabetic youth will be presented
with their pump pack and have an opportunity to “model” the
design that students have created. This grant requests funds to purchase
materials for the pump pack kits for up to 20 diabetic youth materials
including fabric and embellishments.

Dietary intervention and aerobic capacity in elite cyclists
Sports nutrition, an emerging field of practice for registered dietitians,
is the chosen career of the student. She is well-prepared for this study:
she is a certified personal trainer, she gained experience in sports nutrition
as summer intern at the Cooper Institute (Dallas, TX), she participated
in assessment of elite high schools swimmers and has completed a literature
review regarding VO2max assessment. The faculty has extensive expertise
in nutrition and sport performance internationally. The study will explore
the link between nutrition, fitness and performance in elite cyclists.
Comprehensive physical, dietary and aerobic assessments will guide nutrition
guidelines. All assessment equipment is available, except for aerobic
testing, which is critical for assessing baseline and changes in fitness
during training and prediction of fat oxidation. In this study, the interests
of the student and expertise of the faculty will be combined to provide
advanced learning to enhance student’s preparation for her career
in sports nutrition. Through this vital learning experience, she will
gain knowledge about the relationship between aerobic fitness and exercise
fueling, important experience in research, cross-train with the faculty
in assessment techniques, and obtain real-life experience in designing
nutrition guidelines for enhanced aerobic performance. Of major advantage
to the faculty, is learning more about nutrition guidance and performance
outcomes in aerobic sports, establishing aerobic testing protocol that
will enhance her field of expertise and provide future avenues of learning
and research. This team effort will be enable us to complete the research
in one semester, impossible to find the time to do individually.
The purchase of the equipment to assess aerobic capacity is pivotal; without
it, no aerobic assessment is possible.

Physician Perceptions of Physical Therapy: A Pilot Study
The purpose of this descriptive survey research was to explore
physicians’ perceptions of the education and skill set of the profession
of physical therapy. A sample of 63 Central Illinois family practice physicians
who are members of a practice-based research network known as the Ambulatory
Network for Scholarship and Research were mailed a survey which was developed
from the Normative Model of Physical Therapy Education and a demographic
form. Thirty-four surveys were returned. Frequency counts for demographics
data as well as means and cross tabulations for the knowledge and skill
sets data were analyzed using SPSS. Of the participants, 58.8% were introduced
to physical therapy during medical school, primarily through observation;
20.5% reported that there is a graduate degree requirement for entry level
physical therapist; and 17.6% were uncertain as to the minimum entry level
requirement. Physicians were asked to rank physical therapy education
and skills from not skilled to expert. Physicians rated physical therapist
as less than competent in taking vitals as well as in head, eyes, ears,
nose and throat; cardiopulmonary, developmental delay, abdominal, cancer
and metabolic disease screenings. With the progressive changes in the
physical therapy education both in degree and content, it is apparent
that physicians are unaware of the depth and breadth of physical therapy
education and the basic skills of a physical therapist. There is still
a need to educate physicians on the physical therapy education and skill
set.

Use of an Arts Program to Promote Self Expression and Communication
in a Population of Chronically Homeless Men
This Special Emphasis collaboration proposes to develop and
present an arts program, in collaboration with nursing students, for the
men in the Safety Net program at the Salvation Army. Men in Safety Net
are a chronically homeless population, many of whom exhibit symptoms of
mental illness and substance abuse. Nurses have many responsibilities
in the engagement of persons with mental illnesses; specifically a duty
to develop therapeutic relationships and facilitate client self-expression.
Populations such as the men in Safety Net often feel isolated and have
difficulty expressing themselves. In nontraditional psych mental health
settings nurses must be creative in ways to engage clients who may need
treatment, but do not meet the requirements for hospitalization. We believe
an arts program using hand-drumming, vocal music, and spoken word/poetry,
embedded within our standard clinical experiences, may address client
issues of isolation and difficulty in self-expression. Eight nursing students
enrolled in the psych mental health nursing practicum, have volunteered
to participate in a clinical experience that uses artistic expressions
as a communication medium. Each week, the students will engage the men
using the aforementioned techniques for a total of eight meetings under
the guidance of faculty member Wendy Kooken, PhD(c), RN and arts experts
from the community. Progress will be measured by weekly student logs;
client attendance, client and students comments, and the preparation of
a manuscript for publication.

Axial Behavior of Reinforced Concrete Columns
This research investigates the behavior of reinforced concrete columns
subjected to axial load. The columns are reinforced and confined with
single (common) spiral and double and opposing (new technique) spirals
in order to enhance their strength and ductility or to increase the spiral
spacing (pitch) to facilitate the flow of concrete during construction.
The new confinement technique is meant to increase the spacing of the
confining spiral without jeopardizing the strength and ductility of the
column or to improve the ductility and strength without reducing the spiral
spacing and hindering the flow of concrete during construction. Eighteen
reinforced concrete circular columns confined with different reinforcement
content will be experimentally tested subjected to concentric axial compressive
loading. The axial force, axial displacement and strains in the concrete
and confining and longitudinal reinforcement will be measured during the
testing. The columns are 1000 mm long and 350 mm diameter. The experimental
results will be compared and utilized to develop design guidelines of
reinforced concrete columns using the new confinement technique. The design
guidelines will facilitate the implementation of the new technique in
deign codes and standards such as the American Concrete Institute (ACI)
to be used by structural engineers.

The Collaborative Development and Presentation of Elmer Rice's 'The
Adding Machine'
The project will join students, faculty, and staff from the Department
of Theatre Arts and the Multimedia Program at Bradley University with
student, faculty, and staff from the University of Waterloo (Canada),
the University of Central Florida (USA), and Cumbria School of the Arts
(UK) to collaboratively develop, rehearse, and present a fully mediatized
production (integrating virtual scenery, broadcast video via Internet2,
recorded video, avatar performers, photographs, graphics and sound) of
Elmer Rice's The Adding Machine. Written by Nobel Prize winning
author Elmer Rice in 1923, The Adding Machine is a funny and
slightly nightmarish look at advancing technology and its effect on human
relationships. The play chronicles the life of Zero, a hapless cog spinning
aimlessly in the corporate word, who, after 25 year of service, is replaced
by a machine. Scheduled for performance in March 2007 as part of Bradley
University Theatre's performance season, students and faculty from all
four institutions will work together on a peer level over the year to
conceptualize, problem-solve, establish methods, determine best practices,
develop proof-of-concepts supporting the integration of technology into
a live performance event, and create the mediatized and theatrical design
elements that will be utilized in rehearsal and presentation. This collaboration
will be facilitated through a process of joint decision-making and interdependent
critical thinking, with a hierarchy appropriate to our disciplines, and
shared responsibility by the students and faculty for the process and
final outcome of the collaboration.
