The Emerging Oral Pathogen, Filifactor Alocis, Modulates Antimicrobial Responses In Primed Human Neutrophils., Ian J. Snider

College of Arts & Sciences Senior Theses

Periodontitis is an irreversible, chronic inflammatory, infectious disease of the oral cavity that affects approximately half of all adults 30 years or older in the USA. The oral cavity is under high immune surveillance because of its constant exposure to microbes in the environment. The primary immune cell responsible for this surveillance is the neutrophil. Pathogens associated with periodontitis possess virulence factors and have evolved strategies to evade neutrophil antimicrobial responses to survive. One such pathogen is Filifactor alocis, whose presence is associated with the progression of periodontitis. F. alocis manipulates several neutrophil antimicrobial functional responses to avoid killing, an …

Impacts Of Dietary Restriction On A Drosophila Model Of Werner Syndrome, Eileen Sember

College of Arts & Sciences Senior Theses

Werner syndrome (WS) is an autosomal recessive disorder that results in premature aging and occurs in 1 in 1,000,0000 to 1 in 10,000,000 people. In humans, WS is the result of mutations that render the WRN gene, that contains a helicase and an exonuclease domain, non-functional. Currently, there is no cure for WS in humans, making dietary and lifestyle interventions attractive for increasing the quality and longevity of lives. Diet restriction (DR) has been shown to extend the lifespan of several model organisms, including Drosophila melanogaster, making it a strong candidate for WS treatment. In this thesis, mutant flies …

Markey Cancer Center Faculty Publications

HER2–targeted treatments have improved survival rates in HER2+ breast cancer patients, yet poor responsiveness remains a major clinical obstacle. Recently, HER2+ breast cancer cells, both resistant and responsive to HER2–targeted therapies, have demonstrated sensitivity to poly–(ADP– ribose) polymerase (PARP) inhibition, independent of DNA repair deficiencies. This study seeks to describe biological factors that precede cell viability changes in response to the combination of trastuzumab and PARP inhibition. Treatment response was evaluated in HER2+ and HER2– breast cancer cells. Further, we evaluated the utility of 3′–Deoxy–3′–[18F]–fluorothymidine positron emission tomography ([18F]FLT–PET) imaging for early response assessment in a HER2+ patient derived xenograft …

Impact Of Lyophilization On Porcine Hemoglobin Properties., Mustafa Almosawi

College of Arts & Sciences Senior Theses

Blood transfusion is the single most often performed lifesaving procedure in hospitals worldwide. Unfortunately, packed red blood cells (RBCs) used for transfusion can only be stored for 42 days at 4 °C before being discarded due to irreversible damage that occurs during storage. Any reduction in available RBCs for an extended period can lead to blood shortages. To increase the shelf-life of RBCs, we investigated freeze-drying (lyophilizing) in the presence of the non-toxic sugar trehalose as a method for long-term preservation. However, the oxidative stress of the lyophilization and storage processes can compromise the functionality of these cells, and the …

Social Media And Wellbeing, Aditya Adsule

Honors College Theses

This psychology thesis paper investigates the existing body of scientific literature surrounding the effects of social media on the wellbeing of adolescents and adults ages 18-29. The current body of scientific literature supports the overall finding that social media has a negative impact not only on mental health, but on physical health. There are also key findings showing the impact of social media on other facets of life such as sleep patterns, social interactions, and physical activity. Current intervention therapies need to be revisited and the DSM categorization of social media addiction needs to be investigated further.

Phenotype Characterization Of Genetic Murine Mouse Models Of Developmental Dysplasia Of The Hip (Ddh), Stephanie Mrowczynski, Kevin Baker, Michael Newton

Posters

Developmental dysplasia of the hip (DDH) is a congenital hip alteration that changes the “ball in socket” movement of the leg inside the pelvis. Genome-wide association studies have identified CX3CR1 polymorphisms associated with increased risk of Developmental Dysplasia of the Hip. Mouse models of CX3CR1 knock-out (KO) mice show unilateral, bony discrepancies between the femur head and acetabulum in comparison to wild-type (WT) mice, as well as gait impairment similar to that of humans with osteoarthritis (which develops in DDH patients later in life). The primary goal of this project is to assess joint congruity in a CX3CR1 KO model …

A Dna-Peptide Crosslink (Dpc) Increases Mutagenicity In Sos-Induced Escherichia Coli, Alessandra Bassani

Honors Scholar Theses

Bacteria, such as Escherichia coli, have an inducible system in response to DNA damage termed the SOS response. This system is activated when the replicative DNA polymerase (Pol) III encounters a lesion, uncouples from DNA helicase, and single-stranded DNA (ssDNA) accumulates at the replication fork. In this study, we investigated DNA-peptide crosslink (DpC), a common lesion that results from cross-linking of proteins or peptides, UV irradiation, and alkylating agents. To increase survival following formation of a lesion, the SOS response can utilize homologous recombination, translesion synthesis (TLS), or excision repair. With TLS, the levels of DNA Pol II, IV, …

Longitudinal Assessment Of Pharmacy Student Attitudes Towards Mental Illness, Jessica Dillon

Honors Scholar Theses

Background: Mental health stigma in providers is one of the greatest barriers in effective care in psychiatric patients. When patients feel stigma towards them, they have lower levels of self-esteem and lower medication adherence. When training healthcare providers, specifically pharmacists, it is important to assess the effectiveness of training at reducing stigma levels. Previous studies have shown that didactic teaching does not significantly decrease stigma in pharmacy students. However, other studies have shown that students who participated in psychiatric rotations have less stigma surrounding mental health following the rotation. Currently there are no studies that assess the same students’ stigma …

Faculty, Staff and Student Publications

Lung adenocarcinoma (LUAD) is a deadly tumor with dynamic evolutionary process. Although much endeavors have been made in identifying the temporal patterns of cancer progression, it remains challenging to infer and interpret the molecular alterations associated with cancer development and progression. To this end, we developed a computational approach to infer the progression trajectory based on cross-sectional transcriptomic data. Analysis of the LUAD data using our approach revealed a linear trajectory with three different branches for malignant progression, and the results showed consistency in three independent cohorts. We used the progression model to elucidate the potential molecular events in LUAD …

Antimicrobial Resistance In Eskape Pathogens And Its Effect On Modern Medicine And Treatment, Cameran Runge

Honors Program: Senior Projects (Public)

Abstract

ESKAPE pathogens (Enterococcus faecium, Staphylococcus aureus, Klebsiella

pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, and Enterobacter

spp.) are seeing a growing resistance to multiple classes of antibiotics. Misuse and overuse of antibiotics have played directly into the resistance observed, and the problem is growing exponentially. Antibiotic resistance is partially due to several intrinsic factors limiting the drug's uptake. These include efflux pumps, increased biofilm production, and reduced cell wall permeability in the resistant bacteria. ESKAPE pathogens also acquire resistance through horizontal gene transfer and plasmids. As antibiotics have become less effective, the bacteria can continue to thrive, leading to a detrimental …
