Behavioral Chronopharmacology Of Cannabinoids In Young And Aged Mice, Erik Lewis Hodges Jan 2020

Behavioral Chronopharmacology Of Cannabinoids In Young And Aged Mice, Erik Lewis Hodges

Electronic Theses and Dissertations

The overarching goal of this research is to explore the biological mechanisms of aging and formulate novel therapeutic approaches to mitigate age-related impairments. The presence and pervasiveness of ~24 hour (circadian) rhythms in molecular and behavioral dynamics suggests that the mechanisms regulating these rhythms are integral to biological aging and possibly amenable to therapeutic interventions. Based on evidence presented in this dissertation, we conclude that the endocannabinoid system is a mediator of both central and peripheral circadian physiology. Additionally, the hormetic pharmacological properties of the synthetic cannabinoid CP55940 suggest that bidirectional modulation of circadian rhythms via cannabinoids is possible. Chapter …

Novel Ophthalmic Formulations For Improved Natamycin Delivery In Fungal Infections Of The Eye., Akash Vijay Patil Jan 2020

Novel Ophthalmic Formulations For Improved Natamycin Delivery In Fungal Infections Of The Eye., Akash Vijay Patil

Electronic Theses and Dissertations

Natamycin (NT) is a front-line drug in the management of ocular fungal infections (OFI). An ophthalmic marketed NT suspension (Natacyn®) is currently the only FDA approved medication prescribed in the pharmacotherapy of OFI. Current NT pharmacotherapy requires frequent topical administration (every hour or 2-hours over 6-8 times in a day) due to it being instilled as eye-drops. This leads to higher precorneal losses and subsequent poor permeation and bioavailability. Therefore, in this research study, alternative ocular formulations of NT were investigated with an intent to improve precorneal retention and corneal permeation in comparison to Natacyn®. Chapter 1 discusses various aspects …

Elucidating The Sloth Hair Microbiome: A Metagenomic Comparison Of Two- And Three-Fingered Sloths, Maya Kaup

Electronic Theses and Dissertations

Sloths are unusual mobile ecosystems containing a high diversity of symbionts living and growing in their fur. These symbionts include poorly studied algae, arthropods, fungi, and bacteria, making sloths likely reservoirs of unexplored biodiversity. I aim to identify gaps and eliminate misconceptions in our knowledge of sloths and their symbionts, and to identify key questions to spur future research into the functions and roles of sloths within a broader ecological and evolutionary context. I also seek to position the sloth fur ecosystem as a model for addressing fundamental questions in microbial and metacommunity ecology. I used whole-community shotgun metagenomic sequencing …

Carceral Matrix: Black Women's Writing In Response To Mass Incarceration, 1963-2019, Allison Michelle Serraes Jan 2020

Carceral Matrix: Black Women's Writing In Response To Mass Incarceration, 1963-2019, Allison Michelle Serraes

Electronic Theses and Dissertations

This dissertation broadens the definition of confinement literature, a critical and developing subfield in African American literary studies. It argues that contemporary Black women writers are the early theorists of the complex and insidious reach of the U.S. prison-industrial complex. Through their probing representations of Black female characters’ interactions with state-sanctioned social control and patriarchal violence, Gayl Jones, Alice Walker, Suzan-Lori Parks, and DaMaris B. Hill expand critical understandings of confinement and imprisonment. This dissertation contends that these writers’ depictions of sexual and reproductive control as part of the developing carceral state reveal how confinement and imprisonment operate on intersecting …

Transgenerational Effects Of Mycoplasma Gallisepticum Infection In Eastern Bluebirds (Sialia Sialis), Sarah Danielle Amonett Jan 2020

Transgenerational Effects Of Mycoplasma Gallisepticum Infection In Eastern Bluebirds (Sialia Sialis), Sarah Danielle Amonett

Electronic Theses and Dissertations

Parents can transmit pathogens to their offspring. Neonatal hosts are particularly vulnerable to infectious diseases, as they have immature adaptive immune systems at birth. In this study, I examine parental transmission of a combacterial pathogen Mycoplasma gallisepticum (MG) in wild eastern bluebirds (Sialia sialis) and its impact on nestling growth. By diagnosing infections in all family members, I confirmed that eastern bluebird nestlings can contract MG infections, and that infection was more comin older nestlings compared to adults and neonates. Furthermore, unlike in other avian hosts, MG infection does not significantly impact nestling body condition. In response to infection, eastern …
