The Effects Of Lipoxin A4 (Lxa4) On Neutrophil Biology In Sepsis, Benedict Wu
The Effects Of Lipoxin A4 (Lxa4) On Neutrophil Biology In Sepsis, Benedict Wu
Graduate School of Biomedical Sciences Theses and Dissertations
During sepsis, neutrophils are inappropriately activated and have prolonged lifespans, thus becoming dysfunctional. Excessive neutrophil activation can lead to tissue injury while neutrophil dysfunction can lead to decreased free radical production and reduced phagocytosis, preventing the host from clearing preexisting infections. Lipoxin A4 (LXA4) is a specialized pro-resolution mediator which reduces neutrophil migration and expression of proinflammatory mediators. Intact neutrophil functions are critical for the host to efficiently clear invading pathogens. The effects of LXA4 on neutrophil function in sepsis have not been established. Using the cecal ligation and puncture (CLP) model of sepsis, LXA4 administered 1 h after sepsis …
Malaria: The Story Of Struggle, Suffering, And Eradication, Stevey Willey
Malaria: The Story Of Struggle, Suffering, And Eradication, Stevey Willey
Honors Projects
Every year over two million men, women, and children around the world are affected by malaria, a disease that can easily be prevented with awareness, education, and support. In April 2014 I held a malaria event in which guests had the opportunity to witness the effects malaria has on people, not just physically, but emotionally and economically as well. The death rate has moved from one person every 30 seconds to one every 60 seconds since 2010. The improvement in the rate of deaths has resulted from the increase in awareness of this disease. It is my goal with this …
The Effects That Liquid And Solid Cattle Manure Have On The Water Quality Of Drainage Ditches In Putnam County, Ohio, Janelle Horstman
The Effects That Liquid And Solid Cattle Manure Have On The Water Quality Of Drainage Ditches In Putnam County, Ohio, Janelle Horstman
Honors Projects
Lake Erie has experienced harmful algal blooms with increased frequency since the mid-1990s due to excess nutrients from Rivers, such as the Maumee River, and largely agricultural watersheds. Nonpoint source pollution from agriculture contributes to eutrophication, algal blooms, and the degradation of water quality. This creates stress on aquatic fauna, reduced aesthetic quality, odor, and limits of the water for usage of drinking, recreation, and industry. This research paper asks what the contributions of having access to manure application records, soil records, and information about antibiotics have on what is known about manure management and antibiotic resistance, which has been …

Attenuating Trigeminal Neuropathic Pain By Repurposing Pioglitazone And D-Cycloserine In The Novel Trigeminal Inflammatory Compression Mouse Model, Danielle N. Lyons
Attenuating Trigeminal Neuropathic Pain By Repurposing Pioglitazone And D-Cycloserine In The Novel Trigeminal Inflammatory Compression Mouse Model, Danielle N. Lyons
Theses and Dissertations--Physiology
Approximately 22% of the United States population suffers from a chronic orofacial pain condition. One such condition is known as trigeminal neuropathic pain frequently reported as continuous aching and burning pain, often accompanied by intermittent electrical shock-like sensations. Dental procedures or trauma are known causes of peripheral trigeminal nerve injury and inflammation. Patients who have this type of facial pain also suffer from emotional distress. For these reasons, trigeminal neuropathic pain needs to be studied in more detail to improve the understanding of the etiology and maintenance of this condition, as well as to develop effective treatment strategies. The first …
Shots, Everybody? : British Anti-Smallpox Vaccination And The Development Of Multifaceted Anti-Vaccine Rhetoric On Internet Parenting Forums, Marta B. Bean
Scripps Senior Theses
Vaccination is an important public health measure that can help reduce disease at the population level. Substantial evidence exists that vaccines are safe and effective at reducing the incidence of diseases like pertussis, measles and cervical cancer. However, on Internet parenting forums, parents discuss whether or not vaccination is the right choice for their children. In this thesis, I highlight the historical context of the anti-vaccine movement in mid 19th century to early 20th century Victorian Britain in the era of compulsory smallpox vaccination. Vaccination in this time was a very different and more overtly dangerous process, and …
Examining The Effect Of Race On The Relationship Between Posttraumatic Stress Disorder And Metabolic Syndrome In Women, Leia Harper
Theses and Dissertations
Posttraumatic stress disorder (PTSD) is a psychiatric condition affecting approximately 8% of the adult U.S. population with rates twice as high in women than men. Increasingly, evidence has suggested a close relationship between PTSD and increased risk of metabolic diseases. However, the literature on PTSD and metabolic disease risk factors has been limited by the lack of investigation of the potential influence of race on this relation. The current study examined the possible effect of race on the relation between PTSD and metabolic risk. Data for this study were provided from sample of that included 50 African American women and …
Ajulemic Acid Induces Cell Death In Retinoblastoma Cells, Emily A. Evans
Ajulemic Acid Induces Cell Death In Retinoblastoma Cells, Emily A. Evans
Honors Theses
Retinoblastoma is a cancer of the retina affecting one in every 15,000-20,000 births. It is normally diagnosed in infancy or early childhood and although it is treatable, enucleation is commonly required. Other treatments include radiation, photocoagulation, or cryotherapy and are often followed by chemotherapy. In an attempt to find an alternate method of treatment that lowers the frequency of enucleation and the serious side-effects resulting from current treatments, ajulemic acid (AJA), a synthetic derivative of Cannabis, has been used to treat retinoblastoma cells. Thus far, significant cell death has occurred among retinoblastoma cells that have been treated with AJA concentrations …

Impact Of Positive And Negative Health Behaviors On Female Mice And/Or Their Offspring, Kristen M. Platt
Theses and Dissertations--Pharmacology and Nutritional Sciences
Obesity is an ever-growing concern in the developed world that carries with it a plethora of health issues. For example, obesity increases an individual’s risk for Type 2 Diabetes and cardiovascular disease. Pregnancy is a vital time for a woman to maintain optimal health, both for her own benefit as well as that of her offspring, and yet almost half of women in the United States who are of age to bear children are overweight or obese. In mice, we found that offspring born to dams fed a high fat diet did not have impaired glucose tolerance, contrary to our …

Williams Honors College, Honors Research Projects
Both scientists and clinicians have proposed tissue engineering as the future of medicine. The possibilities for tissue engineering, that is, fabrication of tissues and organs in the laboratory and their translation to patients, appear to be endless, and many believe that this new approach in medicine will result in abolishing many common ailments, injuries, and congenital defects. Injuries to a tendon enthesis, the normal tissue connection between tendon and bone, are of particular concern to clinicians because of their frequency and failure to repair as a result of surgery. While these injuries may not be life threatening, they can certainly …

The second interview occurred six to twelve months later, and …
Plasma Insulin-Degrading Enzyme: Characterisation And Evaluation As A Potential Biomarker For Alzheimer's Disease, Michelle Tegg
Plasma Insulin-Degrading Enzyme: Characterisation And Evaluation As A Potential Biomarker For Alzheimer's Disease, Michelle Tegg
Theses: Doctorates and Masters
Alzheimer’s disease (AD) is increasing in prevalence due to increasing lifespan and altered lifestyle. It is the fourth major cause of death in Western countries, resulting in significant economic and social impact (Von Strauss, et al., 1999; Goate, 1997). There are no blood biomarkers currently accepted for the diagnosis of AD, and the identification of suitable biomarkers would eventually reduce the necessity for invasive, expensive and slow diagnostic procedures, as well as facilitate prognostic studies. An AD blood test would decrease the need for delaying diagnosis due to ambivalent presentation, and allow therapeutic intervention to commence at an earlier …
Novel Therapeutic Strategies For Pancreatic Cancer, Bridget A. Quinn
Novel Therapeutic Strategies For Pancreatic Cancer, Bridget A. Quinn
Theses and Dissertations
Pancreatic cancer is a devastating disease that leaves patients with a very poor prognosis and few therapeutic options. Many of the treatment options available are the same that have been used for almost 2 decades. There is a dire need for both novel treatments for this disease as well as novel strategies of treatment. This body of work will introduce and provide evidence in support of a novel combination therapy for pancreatic cancer treatment, a novel strategy of modifying currently used chemotherapeutics for pancreatic cancer therapy, and a novel transgenic preclinical mouse model of pancreatic cancer. Sabutoclax, an antagonist of …
Application Of Marginal Structural Models In Pharmacoepidemiologic Studies, Shibing Yang
Application Of Marginal Structural Models In Pharmacoepidemiologic Studies, Shibing Yang
Theses and Dissertations
Background: Inverse-probability-of-treatment-weighted estimation (IPTW) of marginal structural models was proposed to adjust for time-varying confounders that are influenced by prior treatment use. It is unknown whether pharmacoepidemiologic studies that applied IPTW conformed to the recommendations proposed by methodological studies. In addition, no previous study has compared the performance of different analytic strategies adopted in IPTW analyses. Objectives: This project aims 1) to review the reporting practice of pharmacoepidemiologic studies that applied IPTW, 2) to compare the validity and precision of several approaches to constructing weight, 3) to use IPTW to estimate the effectiveness of glucosamine and chondroitin in treating osteoarthritis. …
Characterization Of Tonb-Dependent Metal Transporters Within Neisseria Gonorrhoeae, Mary Kathryne Dickinson
Characterization Of Tonb-Dependent Metal Transporters Within Neisseria Gonorrhoeae, Mary Kathryne Dickinson
Theses and Dissertations
Neisseria gonorrhoeae, the etiologic agent of gonorrhea, utilizes TonB-dependent transporters to import essential nutrients such as iron. Study of TonB-dependent transporters is extremely important due to the fact that they make excellent vaccine targets. In order to learn more about the structure, function, expression, and regulation of selected TonB-dependent transporters, three goals were established for this study. The first goal was to examine the role of two highly conserved regions of TbpB in lipidation. One of the conserved regions of TbpB, the LSAC motif, was shown to be critical for lipidation. The second goal was to determine whether MisR/MisS regulates …
Comparison Of Two Different Sprint Interval Training Work-To-Rest Ratios On Acute Metabolic And Inflammatory Responses, Christopher R. Harnish
Comparison Of Two Different Sprint Interval Training Work-To-Rest Ratios On Acute Metabolic And Inflammatory Responses, Christopher R. Harnish
Theses and Dissertations
High intensity exercise is believed to yield greater results on health and human performance than moderate intensity exercise. Extensive research indicates that not only do high-intensity interval training (HIT) and sprint interval training (SIT) produce significant improvements in cardiovascular fitness and disease, they may be more effective at improving long-term metabolic function, including insulin sensitivity (Si), by producing more mitochondria. Moreover, compliance rates for HIT and SIT participation are reported to be the same or better than traditional moderate intensity exercise. Because lack of time is often cited as major hindrance to exercise participation, SIT is also seen as a …

Analysis Of The Role Of Astrocyte Elevated Gene-1 In Normal Liver Physiology And In The Onset And Progression Of Hepatocellular Carcinoma, Chadia L. Robertson
Theses and Dissertations
First identified over a decade ago, Astrocyte Elevated Gene-1 (AEG-1) has been studied extensively due to early reports of its overexpression in various cancer cell lines. Research groups all over the globe including our own have since identified AEG-1 overexpression in cancers of diverse lineages including cancers of the liver, colon, skin, prostate, breast, lung, esophagus, neurons and neuronal glia as compared to matched normal tissue. A comprehensive and convincing body of data currently points to AEG-1 as an essential component, critical to the progression and perhaps onset of cancer. AEG-1 is a potent activator of multiple pro-tumorigenic signal transduction …
Sildenafil And Celecoxib Interact To Kill Breast Cancer Cells, Brittany Binion
Sildenafil And Celecoxib Interact To Kill Breast Cancer Cells, Brittany Binion
Theses and Dissertations
Breast cancer is the second most commonly diagnosed cancer among American women and is responsible for the second highest number of cancer-related deaths. Targeted therapeutic agents sildenafil, a phosphodiesterase type 5 inhibitor, and celecoxib, a cyclooxygenase-2 inhibitor, have been used individually in conjunction with other chemotherapeutic agents to enhance cell killing in a variety of cancers. Sildenafil when combined with traditional chemotherapeutic drugs, such as the taxanes and anthracyclines, or celecoxib combined with traditional hormone therapies have been used to increase cytotoxicity and cell killing. The data presented here demonstrates that the novel combination of sildenafil and celecoxib work together …
Dopamine And Glutamate Dysfunction In A Rodent Model Of Attention-Deficit/Hyperactivity Disorder: Implications For Future Neuropharmacology, Erin M. Miller
Dopamine And Glutamate Dysfunction In A Rodent Model Of Attention-Deficit/Hyperactivity Disorder: Implications For Future Neuropharmacology, Erin M. Miller
Theses and Dissertations--Neuroscience
Attention-deficit/hyperactivity disorder (ADHD) is one of the most common disorders of childhood. It is theorized to be caused by catecholamine dysfunction in the striatum (Str) and frontal cortex (FC). The spontaneously hypertensive rat (SHR) has been used as a model for ADHD because of its attention deficits, impulsiveness, and hyperactivity. Prior studies of dopamine (DA) in the Str and FC have revealed conflicting results in the SHR compared to control, indicative of a need for a better understanding of DA dynamics in this model. In addition to the DA hypothesis, studies have begun implicating glutamate in the etiology of ADHD. …
