The agr quorum-sensing system links Staphylococcus aureus metabolism to virulence, in part by increasing bacterial survival during exposure to lethal concentrations of H2O2, a crucial host defense against S. aureus. We now report that protection by agr surprisingly extends beyond post-exponential growth to the exit from stationary phase when the agr system is no longer turned on. Thus, agr can be considered a constitutive protective factor. Deletion of agr resulted in decreased ATP levels and growth, despite increased rates of respiration or fermentation at appropriate oxygen tensions, suggesting that Δagr cells undergo a shift towards a hyperactive metabolic …

Characterizing Brain And Skull Mechanics In The Minipig Using Magnetic Resonance Elastography, Shuaihu Wang

McKelvey School of Engineering Graduate Student Theses & Dissertations

Computational models and simulation are important tools to investigate the mechanisms underlying traumatic brain injury (TBI); their accuracy depends strongly on accurate model parameters, including the mechanical properties of the brain and its interactions with the skull. However, most existing TBI modeling studies are performed using material properties derived from animal tissue obtained after death. Magnetic resonance elastography (MRE) provides a non-invasive method for estimating the mechanical properties of soft tissue. The overall objective of this thesis is to characterize the biomechanical properties of brain tissue and brain-skull interface in the minipig by using MRE. This was achieved through pursuit …

Overexpression Of Fatty Acid Synthase Upregulates Glutamine–Fructose-6-Phosphate Transaminase 1 And O-Linked N-Acetylglucosamine Transferase To Increase O-Glcnac Protein Glycosylation And Promote Colorectal Cancer Growth, James Drury, Mariah E. Geisen, Josiane Weber Tessmann, Piotr G. Rychahou, Courtney O. Kelson

Markey Cancer Center Faculty Publications

Fatty acid synthesis has been extensively investigated as a therapeutic target in cancers, including colorectal cancer (CRC). Fatty acid synthase (FASN), a key enzyme of de novo lipid synthesis, is significantly upregulated in CRC, and therapeutic approaches of targeting this enzyme are currently being tested in multiple clinical trials. However, the mechanisms behind the pro- oncogenic action of FASN are still not completely understood. Here, for the first time, we show that overexpression of FASN increases the expression of glutamine–fructose-6-phosphate transaminase 1 (GFPT1) and O-linked N-acetylglucosamine transferase (OGT), enzymes involved in hexosamine metabolism, and the level of O-GlcNAcylation in vitro …

The Immune Contribution To Postpartum Remodeling, Jessica Caroline Ming

Master's Theses

Following parturition, the uterus must undergo significant changes in size and structure through a process called postpartum remodeling. This process is known to have both pro- and anti- inflammatory components. However, how various immune cells contribute to remodeling and the pathways that promote inflammation are not well understood. We hypothesize that immune cells that infiltrate the uterus postpartum modulate inflammation to promote postpartum remodeling. Our preliminary data suggests that inflammatory cell death may contribute to the inflammation present in the early postpartum period, and thus further studies will analyze caspase-1, gasdermin D, and IL-1β and IL-18. To analyze the immune …

Shh Regulates Penile Morphology And Smooth Muscle Through A Mechanism Involving Bmp4 And Grem1, Jiangping Deng, Sarah Martin, Timothy Searl, Samuel Ohlander, Daniel A Harrington, Kevin T Mcvary, Carol A Podlasek

Faculty, Staff and Student Publications

Background: The cavernous nerve (CN) is frequently damaged in prostatectomy and diabetic patients with erectile dysfunction (ED), initiating changes in penile morphology including an acute and intense phase of apoptosis in penile smooth muscle and increased collagen, which alter penile architecture and make corpora cavernosa smooth muscle less able to relax in response to neurotransmitters, resulting in ED.

Aim: Sonic hedgehog (SHH) is a critical regulator of penile smooth muscle, and SHH treatment suppresses penile remodeling after CN injury through an unknown mechanism; we examine if part of the mechanism of how SHH preserves smooth muscle after CN injury involves …

Genetic, In Vitro Phenotypic, And Clinical Characterization Of Atypical Enteropathogenic E. Coli Infection And Pathogenesis, Sarah E. Kralicek

Dissertations

Enteropathogenic E. coli (EPEC) are enteric pathogens that are non-invasive, lack Shiga toxin, and use a type 3 secretion system encoded on the locus of enterocyte effacement (LEE) pathogenicity island to translocate bacterial effector proteins into host intestinal epithelial cells leading to diarrhea. Atypical EPEC (aEPEC), in contrast to typical EPEC (tEPEC), lack bundle-forming pili, likely altering adherence and pathogenicity. Detection of aEPEC with co-infecting pathogens and in some asymptomatic individuals leads to questions regarding aEPEC virulence, especially in adults. I aimed to characterize the clinical manifestations of aEPEC infection and the genetic and in vitro phenotypic factors that contribute …

Elucidating The Underlying Mechanisms Polyamines Play On Coxsackievirus B3 Infection, Mason Richard Firpo

Dissertations

Polyamines are a class of metabolites consisting of small carbon chains that contain amine groups and are positively charged at cellular pH. They play many important roles within the cell and are necessary for cell growth, membrane function, transcription, and translation. They are also required by a myriad of viruses for a productive infection. This includes the non-polio enterovirus Coxsackievirus B3 (CVB3). CVB3 is a cardiotropic virus that can readily infect the heart and cause irreversible damage which can eventually lead to dilated cardiomyopathy and the need for a heart transplant. Unfortunately, there are no approved antivirals or vaccines that …

A Masculine Housewife With Taste; Austrian Traveller Ida Pfeiffer In The Netherlands East Indies (1851-1853), Rick Honings

Wacana, Journal of the Humanities of Indonesia

In the spring of 1851, Austrian traveller and writer Ida Laura Pfeiffer (1797-1858) embarked on her second trip around the world. Her overseas travels also took her to the Netherlands East Indies (now Indonesia): to Borneo (now Kalimantan), Java, Sumatra, and Celenbes (now Sulawesi). She described her experiences in her book Mijne tweede reis rondom de wereld (1856b), the Dutch translation of her German book Meine zweite Weltreise (1856a, ‘My second world tour’). In the last decades, much has been written about the perspective of female travel authors. On the one hand, nineteenth-century Western women travellers were curtailed because of …

Sexualizing And Pathologizing The Other; Reading Doctor Julius Karel Jacobs’S Travel Account To Bali In The Nineteenth Century, Gani A. Jaelani

Wacana, Journal of the Humanities of Indonesia

Since their arrival in the seventeenth century, through the nature of their calling – from the examination of the sick and efforts to acquire knowledge of local medicines – European physicians in the Netherlands East Indies inevitably encountered the local people and their customs. When contact intensified with more frequent journeys into the hinterland, these physicians produced knowledge of the natural world, the culture, and the customs of the region. However, when reading, the travel account of Doctor Julius Karel Jacobs, a Dutch colonial official physician to Bali in 1881, we are offered another perspective. This article discusses how the …

Tourist Cycling Trips In The Tropics; The Ideological Landscape Of Recreational Bike Rides In The Former Netherlands East Indies At The End Of The Nineteenth Century, Nick Tomberge

Wacana, Journal of the Humanities of Indonesia

Although previous research shows that the introduction of bicycles drove recreational travel in Western Europe, North America, and Australia, to this day, little is known about tourist cycling in other parts of the world. Nevertheless, a broader geographical context is desirable: the study of the early days of tourist cycling in former European colonies in Southeast Asia can enhance our understanding of the strong political dimensions of tourist travel in a colonial context, as it is interconnected with the project of imperialism, technological change, and modernity. This article examines the early days of tourist cycling in the former Netherlands East …

Cross-Cultural Encounters In Polish And Russian Travelogues About Colonial Indonesia, 1870s-1910s, Tomasz Ewertowski

Wacana, Journal of the Humanities of Indonesia

This article explores cross-cultural encounters and identities discourses in selected Polish and Russian travelogues about the Netherlands East Indies. Poles and Russians could travel to the Netherlands East Indies thanks to advantages afforded Europeans by the colonial system. Their occupations (for example, a privileged tourist, colonial scientist, diplomat) often made them suitable imperial agents. They defined themselves as Europeans but, as Eastern Europeans, they occupied an ambiguous position: Russians came from a land-based, economically backward “empire of the periphery“ (Boris Kagarlitsky 2008); Poles came from a semi-peripheral European nation subjected to foreign rule and, from their common experience of subjugation, …

Sowing The Gospel In The Southern "Vorstenlanden"; Wonogiri In The Protestant Evangelists’ Travelogues In The Early Twentieth Century, Adi Putra Surya Wardhana, Dennys Pradita

Wacana, Journal of the Humanities of Indonesia

The goal of this study is to analyse the travelogues of Protestant evangelists in Wonogiri, a topic so far barely touched upon. Despite being a predominantly Muslim community, Wonogiri was one of the areas in the principalities of Surakarta targeted by the zending. Therefore, this study explores various aspects, including the purpose behind the visits of Protestant missionaries, the discourses presented in the travelogues, and the perspectives of these evangelists on the belief system prevalent in the community in the early twentieth century. Based on several travel accounts, this research utilizes a critical discourse analysis approach. The evangelists built …

"Merdeka"! And The Dynamics Of Extreme Violence; The First Year Of The Indonesian Revolution Through The Eyes Of Three Dutch Journalists, Coen Van 'T Veer

Wacana, Journal of the Humanities of Indonesia

In the first year after World War II, there was a power vacuum in Indonesia. The Indonesians had declared their independence. The Allies had assigned the administration of the former Dutch colony to the British. The Dutch thought they could continue their colonial ambitions. It was a year of utter chaos and extreme violence. While most Dutch journalists remained in Jakarta, three went to the war zones: two of them as reporters and the other as a soldier. The analysis of three texts on the first year of the Indonesian War of Independence by Dutch eyewitnesses shows the importance of …

Modelling The Combined Use Of Long-Lasting Insecticidal Nets And Insecticides Zooprophylaxis Against The Resilience Of Anopheles Arabiensis For Effective Malaria Control, Watson Levens

Tanzania Journal of Science

Malaria is a significant public health concern, especially in tropical regions. It remains endemic in many areas where malaria mosquitoes are prevalent. This study investigates the viability of insecticide zooprophylaxis (IZ) in conjunction with Long Lasting Insecticidal Nets (LLINs) as a strategic approach to combat malaria transmission, particularly in regions dominated by zoophagic vectors. Through the presentation and analysis of a mathematical model that integrates IZ and LLINs for the control of Anopheles arabiensis (An. arabiensis), the research underscores IZ's role in reducing zoophagic vector populations and enhancing malaria control efforts. Notably, the study reveals that achieving comprehensive coverage of …

What Is Trauma?: From Science To Social Justice, Judith Fleetwood Carlisle

Arts & Sciences Graduate Student Theses and Dissertations

In recent years, the term “trauma” has become increasingly controversial. Many of these controversies revolve around the definition of trauma, and the way that this definition varies across contexts. What kinds of experience can plausibly be considered “traumatic”? In some contexts, the standards are incredibly permissive, while others are much more restrictive. These different ways of understanding “trauma” prompts an important question: Who has the authority to define trauma? In other words, who decides which conception of trauma is the most “legitimate” – who decides when an experience is or is not traumatic? My project attempts to answer these questions …
