Dietary Polyphenols, Resveratrol And Pterostilbene Exhibit Antitumor Activity On An Hpv E6-Positive Cervical Cancer Model: An In Vitro And In Vivo Analysis, Kaushiki Chatterjee, Sumit Mukherjee, Jonathan Vanmanen, Probal Banerjee, Jimmie E. Fata

Publications and Research

Human papilloma virus (HPV)-induced cervical cancer is one of themost frequent cancers in women residing in underdeveloped countries. Natural compounds like polyphenols continue to be of scientific interest as non-toxic effective alternative treatments. Our previous work showed the efficacy of two polyphenols, resveratrol, and pterostilbene on human HeLa cells. Here we explored the in vitro anti-cancer activity and in vivo anti-tumor potential of these two structurally similar compounds on HPV oncogene E6 and E7 positive murine TC1 cells. In vitro analysis confirmed the cytotoxic potential of both resveratrol and pterostilbene compounds with each having a low IC50 value and each …

Probing The Formation Of Reactive Oxygen Species By A Porous Self- Assembled Benzophenone Bis-Urea Host, Baillie A. Dehaven, Hannah K. Liberatore, Alexander Greer, Susan D. Richardson, Linda S. Shimizu

Publications and Research

Herein, we examine the photochemical formation of reactive oxygen species (ROS) by a porous benzophenone-containing bis-urea host (1) to investigate the mechanism of photooxidations that occur within the confines of its nanochannels. UV irradiation of the self-assembled host in the presence of molecular oxygen generates both singlet oxygen and superoxide when suspended in solution. The efficiency of ROS generation by the host is lower than that of benzophenone (BP), which could be beneficial for reactions carried out catalytically, as ROS species react quickly and often unselectively. Superoxide formation was detected through reaction with 5,5- dimethyl-1-pyrroline N-oxide in the presence of …

Genetic Diversity Of Local Canines Assessed By Derived Cleaved Amplified Polymorphic Sequences, Nicole Benmoshe, Jeremy Seto

Publications and Research

Breeding of the dog, Canis Iupus familiaris, over centuries has given rise to the selection of certain traits including size, shape, coat length, color and many behavioral traits. Inbreeding within dog breeds has resulted in the increase of genetic diseases, many of which are similar to human diseases making the dog an exemplary model organism to study. Using dCAPS (Derived Cleaved Amplified Polymorphic Sequences) we can identify SNPs (Single Nucleotide Polymorphisms) in the dog genome using buccal samples collected from four local dogs of different breeds, both large and small. After performing DNA extractions, PCR (Polymerase Chain Reaction), restriction enzyme …

Making It New And Keeping It Old: Recasting Frameworks And Contexts In Georgia O’Keeffe Studies, Linda M. Grasso

Publications and Research

Three recent Georgia O’Keeffe exhibition catalogues devise new interpretative frameworks and situate O’Keeffe in new contexts that are especially relevant to American Studies scholars interested in visual culture, material culture, gender studies, reception studies, and modernism. One places O’Keeffe in the company of other white women making modernist art in the early decades of the twentieth century; another provides critical interpretations that acknowledge and reject previous views that were skewered by monolithic gender and sexual lenses; and a third moves O’Keeffe into popular culture domains such as fashion, consumerism, and interior design. Raising questions about how curators present and shape …

Partnering For Social Justice: Social Work Students’ Placement At Public Libraries, Sarah C. Johnson

Publications and Research

While the collaborative trend among professional social workers and librarians is garnering much deserved attention, literature about social work students partnering with public libraries is virtually nonexistent. Public librarians can advocate for social justice by initiating partnerships with master-level social work (MSW) students to enhance small- and large-scale programs to address the unique needs of patrons. In this chapter, I highlight existing collaborations among public libraries and student social workers to raise awareness of possibilities.

Nestler, Ming-Hu Han, James W. Murrough

Publications and Research

Major depressive disorder (MDD) is a leading cause of disability worldwide, yet current treatment strategies remain limited in their mechanistic diversity. Recent evidence has highlighted a promising novel pharmaceutical target—the KCNQ-type potassium channel—for the treatment of depressive disorders, which may exert a therapeutic effect via functional changes within the brain reward system, including the ventral striatum. The current study assessed the effects of the KCNQ channel opener ezogabine (also known as retigabine) on reward circuitry and clinical symptoms in patients with MDD. Eighteen medication-free individuals with MDD currently in a major depressive episode were enrolled in an open-label study and …

The State Of White Supremacy In America: It Is Time To Stand Together, Remi Alapo, David Rockefeller

Publications and Research

The United States has numerous social-cultural issues affecting its population. One of these problems is white supremacy. This concept refers to a racist perception that white persons are naturally superior to individuals of other races and should thus dominate them. While white supremacy in previous centuries galvanized a lot of support among white people, the concept is now regarded vicious by white, African American, Latino as well as other races. The modern American society is structured under cultural sensitiveness, racial equality, and religious tolerance. Unlike the years of slavery or reconstruction, all citizens in the United States are afforded equal …

Modeling Changes In Cellular Micro-Environment In Mild To Moderate Head Trauma, Xiangfu Zhang, Subhendra N. Sarkar Phd, Rt

Publications and Research

Our work aims to connect and model multiple small, inter-related tissue injuries as a consequence of mild traumatic brain injuries (mTBI). It has been shown that frontal and temporal lobes are vulnerable regions for brain traumatic injury. A brain injury from a blow or high-speed impact can cause undersurface of the frontal and temporal lobes to deform against the anterior and cranial fossae. This deformation can often trigger damage to the cerebral vasculature, which is ill-understood and can result in chronic damage to larger vessels over time. These physiological injuries can be manifested psychologically; such as patients’ sleep-wake disturbances. The …

Hiding In The Lianas Of The Tree Of Life: Molecular Phylogenetics And Species Delimitation Reveal Considerable Cryptic Diversity Of New World Vine Snakes, Robert C. Jadin, Christopher Blair, Michael J. Jowers, Anthony Carmona, John C. Murphy

Publications and Research

The Brown Vine Snake, Oxybelis aeneus, is considered a single species despite the fact its distribution covers an estimated 10% of the Earth’s land surface, inhabiting a variety of ecosystems throughout North, Central, and South America and is distributed across numerous biogeographic barriers. Here we assemble a multilocus molecular dataset (i.e. cyt b, ND4, cmos, PRLR) derived from Middle American populations to examine for the first time the evolutionary history of Oxybelis and test for evidence of cryptic lineages using Bayesian and maximum likelihood criteria. Our divergence time estimates suggest that Oxybelis diverged from its sister genus, Leptophis …

Corequisite Mathematics Remediation: Results Over Time And In Different Contexts, Alexandra W. Logue, Daniel Douglas, Mari Watanabe-Rose

Publications and Research

Traditional mathematics remediation is based on the theory that traditional mathematics remedial courses increase students’ subsequent academic performance. However, most students assigned to these courses do not pass them, and thus cannot graduate. An alternative approach, corequisite remediation, assigns students instead to college-level quantitative courses with additional academic support, often aligned to a student’s major. Here we report the longer-term results of a randomized controlled trial comparing corequisite remediation (with statistics) and traditional algebra remediation (297 students per group). The corequisite group not only demonstrated significantly higher quantitative course pass rates, but also success in many other disciplines, as well …

'Lui' And 'Egli' In Il Gattopardo, Joseph C. M. Davis

Publications and Research

A semiotic, discourse-based linguistic hypothesis that bypasses the syntactic category subject and proposes instead contrasting meanings for the pronouns lui and egli provides empirical support for the critical interpretation of the novel Il Gattopardo as being anti-teleological. The hypothesis, which applies to large body of twentieth-century Italian literature, is that egli but not lui bears a linguistic meaning that ties its relevance to a verb. This linguistic hypothesis reveals a significant difference in Tomasi di Lampedusa’s portrayals of the novel’s two characters Don Fabrizio and Don Calogero: one as a character defined by who he is, the other as a …

Titanium Dioxide Sensitized With Porphyrin Dye As A Photocatalyst For The Degradation Of Water Pollutants, Kevin Reyes, Ivana Jovanovic

Publications and Research

TiO2 was sensitized with a porphyrin, Tetra(4-carboxyphenyl) porphyrin(TCPP) and used as photocatalyst under visible light for degradation of aqueous solutions of methylene blue (MB) dye. The quantification of the degradation of MB was assessed by UV-Vis spectroscopy. The results of this procedure showed the decrease in concentration of MB over time when reaction is exposed to visible light. The TiO2-TCPP complex was tested as well for the recovery of metals from the AgNO3 aqueous solution. The reduction of silver cations to silver metal was observed through formation of black precipitate.

The Dionysus Project: Classifying & Monitoring Vineyards With Satellite Remote Sensing & Image Analysis, Evelin Perez-Flores, Nicole Flores, Rachel Zinberg, Dionne Huston, Aaron Davitt, Kyle Mcdonald

Publications and Research

Climate change is expected to impact the wine industry by shifting suitable growing regions away from established regions and increasing the demand for freshwater supplies to maintain vineyard health. This creates challenges for maintaining vineyards since the grapevines need to be appropriately stressed to produce quality grapes for quality wine. This requires precision management of freshwater application and canopy management to produce a grape that has the appropriate concentration of flavors and sugars. Vineyards in the U.S. are typically monitored by vineyard managers at the large scale, lacking the resolution needed to identify grapevine growth at the subfield level. Vineyard …

As students we often wonder why some subjects are easy to understand and requires not much effort in terms of re-reading the material, for us to grasp what it entails. One subject seems to remain elusive and uneasy for a vast majority of learners at all levels of education; that subject is Mathematics, it is one subject that most learners finds difficult even after doubling the amount of time spent on studying the material. My intention is to explore ways to make Mathematics easier for other students using feedback from students enrolled in NSF mathematics peer leading workshops, and use …

A Comparative Study Of Incidence Of Domestic Violence Between Immigrant And Non-Immigrant Women In The United States Of America, Nadia A. Gordon, Urmi Ghosh-Dastidar, Janet Liou-Mark, Shamita Dasgupta

Publications and Research

Immigrant women in the USA come from various socio-economic, cultural, and religious backgrounds. Some of these women suffer from domestic violence; however, due to their strict cultural or social structure, they often stay quiet and rarely report these incidents to the authorities. Additionally, since these immigrant women face more challenges than their non-immigrant peers, they are more reluctant or unlikely to leave their abusive partners. An analysis was completed using published data as an attempt to establish if any statistically significant differences exist between reported incidences among immigrant women and non-immigrant women. A chi-square analysis (χ² = 14.53; p-value …
