Making DEBIs Work: Ohio's Implementation Experience
The Ohio HIV Evaluation and Training Project (OHETP)
has conducted a study to identify key issues, successes,
and barriers in the implementation of Diffusion of
Effective Behavioral Interventions (DEBI) programs,
which are science-based, community-and group-level HIV
prevention interventions designed for community-based
service providers and state and local health
departments.

Optimal Growth Conditions for Tracheal Epithelial
Stem Cells
Epithelial cells regulate the physiological
functions of most organs. Furthermore, the pathogenesis
of diseases like chronic respiratory infection,
metaplasia or tumor formation must be researched using
the tracheal or bronchial epithelium. One practical
method for studying these physiological functions and
pathogenic processes is to culture the epithelial stem
cells in separation from mesenchymal tissue constituents
(Price et al., 1980). Studying epithelial stem cells in
such an in vitro culture system has led to the
understanding of certain functions; however, there are
other functions yet to be understood. Cultured normal
tracheal epithelial cells are very likely to develop
into populations of non-dividing cells. One must address
this major problem in order to establish replicative
cultures of tracheal epithelial cells. In addition,
fibroblasts appear to confine the epithelial outgrowths
from the tissue (Heckman, 1983). To overcome these
problems it was essential to formulate an optimal growth
medium that can maintain a population of growing stem
cells and can restrain the fibroblast growth. A
specifically formulated optimal growth medium, which has
these advantages, is described in this study.

Antifouling Potential of Functionalized Copper
Nanoparticles
Copper (Cu) and its oxides are common biocides in a
large number of commercial antifouling marine paints.
Our research focuses on the functionalization of Cu
nanoparticles (NPs) with acrylic groups, as well as
testing their antibacterial properties. The acrylic
functionality can be copolymerized with other acrylic
monomers. By this, we chemically incorporate the NPs
into the polymer matrix making our active biocide a part
of the polymer backbone and having the potential for
better control of its release. The use of NPs is also
expected to reduce the biocide load, owing to larger
active surface area.

TIKVAH for Interfaith Chorus, Saxophone Quartet,
soprano voice, dance, and digital video
TIKVAH, A Chamber Music Oratorio, created and
conceived by composer Burton Beerman, is inspired by the
memoirs of living Holocaust survivor and Toledo
community member Philip Markowicz, presented at Chicago
Sinai on November 2nd. Chicago Sinai has a proud history
of acting on values and causes that reflect their
commitment to social justice and human dignity. In
writing TIKVAH "Hope", Beerman's goal was to bring
awareness of history through the arts as it relates to
all of society and humanity, paying tribute to all who
have suffered and endured discrimination in our society
and to instill a respect for all mankind. The composer
sought to fill TIKVAH with social commentary that would
guide and provoke audiences to question the world around
them. On one level it is a compelling drama about one
person's life before, during and after the Holocaust. On
another level, Beerman sees it as a dramatic examination
of the psychology of dehumanization and survival. Every
performance production contains a pre concert seminar
about morals, ethics and values, and post concert
"Artist's TalkBack." Special features for this
multimedia musical oratorio will be the Interfaith
Chorus comprised of Chicago's professional choirs from 3
different faiths.

203 Days: Independent Documentaries, original score,
Burton Beerman, produced by Bailey Barash
203 Days, with original score by composer Burton
Beerman, produced by bbarash productions, LLC is a 30
minute documentary film. 203 Days received the CINE
Golden Eagle Award. "The award is recognized
internationally as symbols of the highest production
standards in filmmaking, sound and videography. Among
great talents whose first major awards included the CINE
Golden Eagle are Steven Spielberg and Ron Howard." John
Civetta, MD. Professor of Surgery University of
Connecticut School of Medicine has created a study guide
for 203 Days for medical students and others training to
become health professionals. 203 Days is a half-hour
documentary about facing the death of the matriarch of
the family. It depicts the family's dynamics at work
when Sarah, the terminally ill mother comes to live with
Kaye, her daughter. Sarah and Kaye are faced with the
stress of family conflicts and daily decisions about
pain management, mobility, outside assistance and
medical crises. The viewer sees how Kaye copes with each
step of Sarah's decline and how both Kaye and Sarah
choose to acknowledge impending death in an age where so
much effort is made to distance ourselves from it.
Beerman' s original score was key in establishing the
mood of each scene and as the filming took place "in the
moment" for Sarah, the viewer was given a rare moment of
her response to the music and the peace derived from one
specific passage."

Effect of Protein Structure on the Driving Force
Dependence of Biomolecular Electron-transfer Rates
The effect of protein structure on the driving force
dependence of bimolecular electron-transfer rates is
studied through the use of de novo designed Cu(I)
metalloproteins. The data suggest that the relative
positioning of the redox-active cofactors within the
hydrophobic core of the proteins affects their degree of
electronic coupling to aqueous electron-acceptors. In
the case where the Cu(I) center is buried deeply within
the hydrophobic core of a four-stranded coiled-coil, the
bimolecular rate constants are lowered below the
diffusion limit, allowing inverted Marcus behavior to be
observed. However, when the Cu(I) center is placed
within a more disordered peptide structure, the
electron-transfer becomes faster and Rehm-Weller
behavior is observed. The results indicate how protein
environments can modulate the electron-transfer
reactivity of their inorganic cofactors in a simple way.

The Contemporary Sublime
The presence of place has touched art makers from
cave painters to more contemporary earth works artists.
Earth and sky inspire my work in both a metaphoric and a
tactile sense. The rather small size of my paintings is
meant to reflect the deflation of historical nature
symbols such as mountains or oceans or the vast sky. My
goals are to subvert some of the more naturalistic
visual systems present in, for example painter Caspar
David Friedrich’s work, and to express more paradoxical
and contemporary concerns that I have about the natural
landscape. The culture of humans has become the new
“sublime” force that is capable of transforming the
natural world. I have created a series of paintings
which incorporate elements of the landscape which I
observed on the island of Møn in Denmark and then
assessed the possibilities available for interpretation
of the sublime.

Characterization of a Lambdoid Phage Gene Encoding a
Host Cell Attachment Spike
The first and most crucial step in a bacteriophage’s
life cycle is the absorption step. This entails docking
on to the phage’s host and insertion of its genetic
material. The phi 80 bacteriophage hijacks the FhuA
siderophore receptor to attach to its host cell. In
addition, phi 80 requires TonB in order to insert its
DNA into its host. Although the method of absorption for
phi 80 has been studied, the bacteriophage protein that
mediates this process has not been characterized. While
sequencing the phi 80 genome, a gene was noted that
shows similarity to the tail spike protein of other
closely related lambdoid phages. Similar to those of
other lambdoid phages, the putative spike protein of phi
80 is predicted to have a functional domain near the C
terminus that mediates binding to the FhuA receptor.
Secondly, a putative TonB box is found in the N terminus
that allows for the binding of TonB for entrance into
the cell.

The Relationship between Phonological Working Memory,
Phonological Sensitivity and Incidental Word Learning
Young children learn words very quickly--in fact,
they form initial word representations following one
brief exposure. We investigated cognitive abilities
needed to form an initial word representation, to
discover whether memory skills or phonological (speech
sound) knowledge is the most important predictor of word
learning. Results showed that variance in 4 year old
children's word learning abilities was accounted for by
phonological knowledge, with no independent contribution
from working memory.

Midbrain and brainstem circadian pacemakers of
rodents
Several brain areas synchronize the body’s activity
to the 24-hour day. We have discovered a circadian
(24-hour) rhythm in the mesencephalic trigeminal
nucleus, a group of neurons that control jaw movement.
To measure these rhythms, we monitored the activity of
genes that serve in the biological clocks of the brain.

Ellagic Acid Decreases Proliferation and IGFBP-2 in
LNCaP Human Prostate Cancer Cells
Ellagic acid (EA)is a bioactive compound found in
many berries and nuts. The present study demonstrated
dose-dependent effects of EA in decreasing cell growth
and decreasing the secretion of IGFBP-2 (a growth factor
implicated in prostate cancer)in human
androgen-dependent prostate cancer cells. Thus, the
positive effects of consumption of fruits, nuts, and
vegetables that are rich in bioactive compounds warrant
further investigation.

The aim of the present investigation was to assess
whether P. aeruginosa strains isolated from different
patients in a regional hospital were phenotypically and
genotypically related and, if so, whether they were drug
resistant. Although some strains showed similar
phenotypic and genotypic properties, the majority of
strains showed unique characteristic: the rate of drug

The Influence of HMGB-1 on Estrogen Responsive
Transcriptional Activation of Luciferase Reporter Gene
Driven by a Spectrum of Estrogen Binding Sites
Estrogen receptor proteins (ER) mediate effect of
the hormone estrogen to activate estrogen-responsive
gene expression. Our lab has recently discovered that
estrogen receptor binds to a variety of binding sites
other than those regarded as conventional sites. Genomic
studies have supported these findings and suggest that
these sites may play a greater role in E2-activated
transcription, leading to gene expression events that
may stimulate cell division and breast cancer. A
ubiquitous, highly conserved, nuclear protein, HMGB-1,
enhances ER binding to these sites. This study will
directly test whether ER binding to these sites
stimulates (functional) transcriptional activity (in
vivo) within the cell and the effect of HMGB1 on this
activity.

Feasibility & Effectiveness
The purpose of this study was to explore the
effectiveness and feasibility of a reading intervention
program, called Close Reading (CR), when administered in
a small group setting. CR was designed to help
middle-elementary students with language and reading
difficulties (LRD) acquire strategies and habits that
enable them to become more analytic in their reading.
Results suggested that the CR program is a promising way
to improve decoding and comprehension for struggling
readers in small groups in the upper elementary years.

Electron and Energy Transfer in Platinum(II)
Polyimine Complexes Bearing Aryl- and
Ferrocenylacetylide Units
We describe the synthesis, photophysical and
electrochemical properties of two platinum(II) polyimine
acetylides possessing charge transfer excited states and
two structurally related polyphosphine bearing
platinum(II) complexes as representative model
compounds. Quenching experiments performed on the metal
complexes bearing arylacetylide units with ferrocene
demonstrate that energy transfer occurs within the
diffusion limit. The main focus of this presentation
will be the heteronuclear complexes where the
ferrocenylacetylide unit is introduced within the
structure. The redox chemistry and the nature of the
absorption features of these mixed metal complexes have
been investigated by a variety of voltammetric
techniques and spectroelectrochemical studies. The mixed
valence nature of chemically and electrochemically

Sensors. Synthesis, Photophysics and Sensing Properties
Square-planar d8 metal complexes that stack in the

interactions can be used as sensor materials to detect
volatile organic compounds. Among these materials,
platinum(II) salts are of great interest because a wide
range of chemosensors with unique and fast colorimetric
responses can be obtained by tuning their vapochromism
through modification of the ligand as well as variation
in the counterion. The synthesis of platinum(II)
complexes bearing functionalized terpyridines with
systematic variation in the counterion will be reported.
Their respective solid state colorimetric and

Spectroscopy and electronic structure of
4-substituted naphthalimides
Naphthalimide-based fluorophores demonstrate high
fluorescence and, have sensitivity to solvent effects.
Naphthalimides can form 3 hydrogen bonds like DNA bases
so they can serve for photocleavage of DNA. The
possibility to bind to biologically important molecules
via hydrogen bonds and photochemical properties of
naphthalimides make them attractive objects for
proton-coupled electron transfer studies. In this work
we will present research results of spectroscopic and
electrochemical properties of 4-substituted
naphthalimides combined with excited state calculations.
UV-VIS, emission and femtosecond optical transient
absorption spectra were collected in different solvents.
Christopher Hadad (OSU) and Shubham Vyas (OSU) performed
series of quantum calculations for naphthalimides.
Calculation results were compared with experimental
data. As experiments showed all these compounds have
high fluorescence and can form hydrogen bonds to other
compounds. So in conclusion we can consider
naphthalimides as potential objects for the
investigation proton-coupled electron transfer.

A Longitudinal Study of Adolescent Transition from
Virgin to Non-Virgin Status
Purpose To identify demographic and psychosocial
predictors for early sexual initiation (ESI) among
middle school midwestern suburban and rural youth.
Methods A total of 884 middle school students completed
a pretest and a one year follow-up questionnaire. At
Time 1, 52 reported already having initiated sexual
behavior; the remaining 832 students were included in
our analyses. The sample was 58.5% female, and 92.8%
white, with a mean age of 12.84. At Time 2, 105 (12.6%)
had changed their coital status from virgin to
non-virgin. A stepwise logistic regression was conducted
to explore the relationship between the demographic and
psychosocial variables measured at Time 1 [including
grade, academic performance, mother's education, family
structure, religiosity, self-esteem (school, home and
peer), perceived sexual norms, abstinence selfefficacy,
peer pressure, etc.] and reported sexual behavior at
Time 2. The analyses were conducted separately by
gender. Results For both genders, academic achievement
was positively and peer self-esteem was negatively
related to ESI. Additionally, self-efficacy and
frequency of prayer were negatively related to ESI for
boys and peer pressure, age and traditional family
structure were negatively related to ESI for girls.
Conclusions Risk and protective factors for ESI should
be examined separately by gender. Use of a
facet-specific measure of self-esteem revealed very
different relationships between the peer, home and
school aspects of self-esteem and transition to
nonvirgin status; therefore, researchers are encouraged
to use area specific rather than global measures of
self-esteem.

Effects of polychlorinated biphenyl mixtures on

The environmental pollutant PCB can both act like
female sex hormone (estrogen) and block its action,
depending on the tissue and the status of the animal.
This study found that the density of estrogen receptor
in one area of the brain (hippocampus) was greater than
normal in PCB exposed animals, while the area of the
hippocampus was less than normal. This suggests that the
brain may compensate for PCB exposure during
development.
