Validating Drug Targets Through Inhibition Of Protein-Protein Interactions In Mycobacterium Tuberculosis, Erin C. Driscoll

Honors Undergraduate Theses

Tuberculosis is the leading cause of death by single infectious disease worldwide; novel antibiotics are needed to continue to treat this disease. To goal of this project is to provide proof-of-principle support for the idea that targeting protein-protein interactions (PPI) is an appropriate course for the discovery of new drugs. This study optimized the M-PFC assay, which allows detection of PPI in Mycobacteria, through the use of stronger promoters and inducible expression of a peptide blocker by riboswitch. To accomplish this, promoter induction studies were used to find stronger promoters for the M-PFC, optimization of the riboswitch as a …

Assessment Of Physical Workload, Ergonomic Problems And Prevalence Of Pain Among Low Wage Hotel Housekeepers In Orlando, Rachel Mammen

Electronic Theses and Dissertations

This research study examined the work conditions, ergonomic problems, and prevalence of pain among low wage hotel room cleaners in Orlando. In most hotels, the cleanliness of guestrooms is one of the most important service standards expected by customers. The role of the housekeeper is thus critical to service provision and hotel profitability. The hospitality industry is a major recruiter of low wage workers with the majority working in housekeeping departments. Due to the nature of the research problem, a positivist quantitative approach was adopted although the survey instrument included space for qualitative comments to some of the latter open-ended …

Effects Of An Acute High-Volume Isokinetic Intervention On Circulating Levels Of Tnf-Α And Stnfr: Influence Of Age, Eliott Arroyo Delgado

Electronic Theses and Dissertations

The immune system has been implicated in recovery and muscle regeneration following exercise. In response to muscle damage, the immune system responds with an increase in circulating pro-inflammatory cytokines with the goal of recruiting leukocytes to the damaged area. Tumor Necrosis Factor-alpha (TNF-α), in particular, has been shown to be implicated in both muscle regeneration and muscle wasting. However, it remains unclear whether TNF-α is responsible for the age-related losses in muscle size and function. Also, due to the high clearance rate of TNF-α from circulation, analyzing the circulating levels of soluble TNF-α receptors 1 and 2 (STNFR1 and STNFR2) …

Abdominal Actinomycosis In The Last 10 Years And Risk Factors For Appendiceal Actinomycosis: Review Of The Literature, Marta Lisa-Gracia, Berta Martín-Rivas, Marcos Pajaron-Guerrero, Ana Arnaiz-García

Turkish Journal of Medical Sciences

Background/aim: Actinomycosis is a granulomatous disease caused by filamentous, gram-positive, anaerobic bacteria. Actinomycetes are commensal inhabitants of the oral cavity and intestinal tract but acquire pathogenicity through invasion of breached or necrotic tissue. In abdominal actinomycosis (AA), the appendix and ileocecal region are usually involved. The aim of this study was to characterize patients diagnosed with AA and to establish the risk factors for appendiceal actinomycosis, including a short review of the literature. Materials and methods: We conducted a prospective cohort study of all patients diagnosed with AA in the University Hospital Marques de Valdecilla (Santander-Cantabria) from January 2003 to …

Wheezing, Asthma, And Atopy In Premature Infants At 2 Years Of Age, Sevi̇m Ünal, Ayşenur Kaya, Leyla Bi̇lgi̇n, Emi̇ne Di̇bek Misirlioğlu, Can Naci̇ Kocabaş

Turkish Journal of Medical Sciences

Background/aim: We aimed to evaluate wheezing, bronchial asthma (BA), and atopy in premature infants at 2 years of age via a crosssectional study. Materials and methods: Premature infants at <37 weeks of gestational age (GA) were assessed for atopy by skin-prick test and serum immunoglobulin E level at 2 years of age. The family's and infant's histories of allergy, BA, atopy, and wheezing were obtained by questionnaire and from hospital records. Results: There were 98 infants, with mean birth weight (BW) 1517.4 ± 486.5 g and GA 30.8 ± 2.9 weeks. The frequencies of wheezing, asthma, and bronchopulmonary dysplasia (BPD) were 32.7%, 16.3%, and 14.3%, respectively. Skin-prick tests were positive for 11 subjects, with allergy to cereals for 7 infants, egg for 3, and peanut for 1. Wheezing was related to GA, BW, respiratory distress syndrome, mechanical ventilation, sepsis, asphyxia, smoking, antenatal steroid, BA, palivizumab prophylaxis, number of people in the household, and duration of hospitalization (P < 0.05). Wheezing was negatively correlated to GA. Family history of BA, smoking, and number of people in the household were linked to BA (P < 0.05). Conclusion: Wheezing was related to degree of premature birth, but BA was linked to BA in the family and smoking. Increased gestation should improve the infant's respiratory health up to 2 years of age.

Remote Sensing Observation Of Annual Dust Cycles And Possible Causality Of Kawasaki Disease Outbreaks In Japan, Hesham El-Askary, Nick Lahaye, Erik J. Linstead, William A. Sprigg, Magdi Yacoub

Mathematics, Physics, and Computer Science Faculty Articles and Research

Kawasaki disease (KD) is a rare vascular disease that, if left untreated, can result in irreparable cardiac damage in children. While the symptoms of KD are well-known, as are best practices for treatment, the etiology of the disease and the factors contributing to KD outbreaks remain puzzling to both medical practitioners and scientists alike. Recently, a fungus known as Candida, originating in the farmlands of China, has been blamed for outbreaks in China and Japan, with the hypothesis that it can be transported over long ranges via different wind mechanisms. This paper provides evidence to understand the transport mechanisms …

In Defense Of California's Mandatory Child Vaccination Law: California Courts Should Not Depart From Established Precedent, Stephanie Awanyai

Loyola of Los Angeles Law Review

In the wake of the 2015 measles outbreak in California, California Senate Bill 277 (S.B. 277) was enacted. S.B. 277 repeals the personal belief exemption to California’s immunization requirement for children in public and private educational or child care facilities in the State. While S.B. 277 was enacted to prevent the spread of contagious diseases through mandatory vaccinations of school-aged children, there are objections to this approach. Parents who oppose S.B. 277 contend that S.B. 277 violates their federal and state constitutional rights to make medical decisions on behalf of their child, and infringes on their child’s fundamental state interest …

Generic Drug Policy In The U.S. - Impact On Drug Prices And Shortages, Ravi Gupta

Yale Medicine Thesis Digital Library

Generic medicines offer a significantly cheaper alternative to brand-name drugs and have become an indispensable means of maintaining patient access and adherence to treatments. In recent years, as a result of monopolistic and oligopolistic conditions, generic drugs have begun to increase in price, sometimes exorbitantly. The competitiveness of drug markets with respect to the number of generic manufacturers and the implications for drug prices and shortages have not been systematically studied.

Two main analyses are presented in this study. First, using publicly available information, the timing of generic drug approvals and the total number of generic manufacturers for all small-molecule …

Medical Versus Surgical Management Of Native Joint Septic Arthritis In Adults: A Retrospective Comparison Of Outcomes Within The Va Ct Medical System, Ian Mcconnell

Yale Medicine Thesis Digital Library

Objective: Septic arthritis is a medical emergency with significant associated morbidity and mortality that requires joint drainage in addition to antibiotic therapy. Closed-needle aspiration and surgery (via arthrotomy or arthroscopy) are the standard approaches to joint drainage, though little data exists regarding treatment outcomes with each approach. We compared long-term outcomes for adult patients with septic arthritis of a native joint based on whether they received a ‘medical’ or ‘surgical’ approach to joint drainage.

Methods: We retrospectively reviewed all chart records for patients diagnosed with septic arthritis at the West Haven VA Medical Center between January 2006 and December 2015. …

Ichthyosis: Assessing Severity And Genotype-Phenotype Correlations, Nareh Valerie Marukian

Yale Medicine Thesis Digital Library

The ichthyoses, also known as disorders of keratinization (DOK), encompass a group of genetic skin disorders linked by the common finding of abnormal barrier function, which initiates a default compensatory pathway of hyperproliferation, resulting in the characteristic clinical manifestation of localized or generalized scaling.

Ichthyoses are a highly heterogenous group of disorders, both genetically and clinically. Despite the identification of causative mutations in over 50 genes, clear genotype-phenotype correlations have been difficult to establish due to the rarity of the ichthyoses and because mutations in the same gene can have widely divergent phenotypes, even in individuals with the same disease-causing …

Synthesis And Characterization Of Poly(Simvastatin) - Incorporated Copolymers And Blends For Bone Regeneration, Theodora Asafo-Adjei

Theses and Dissertations--Biomedical Engineering

Common biodegradable polyesters such as poly(lactic acid) (PLA), poly(lactic-co-glycolic acid) (PLGA) and poly(ε-caprolactone) (PCL) are used as drug delivery vehicles for tissue regenerative applications. However, they are typically bioinert, with drug loading limitations. Polymerizing the active agent or precursor into its respective biodegradable polymer would control drug loading via molar ratios of drug to initiator used for synthesis. Simvastatin was chosen due to its favorable anti-inflammatory, angiogenic, and osteogenic properties. In addition, its lactone ring lends itself to ring-opening polymerization and, consequently, the synthesis of poly(simvastatin) with controlled simvastatin release.

Simvastatin was first polymerized with a 5kDa methyl-terminated poly(ethylene glycol) …

Role Of Intracellular Growth During The Gastrointestinal Stage Of Listeria Monocytogenes Infection, Grant Steven Jones

Theses and Dissertations--Microbiology, Immunology, and Molecular Genetics

Listeria monocytogenes is a facultative intracellular bacterium that causes foodborne disease in humans. L. monocytogenes invade the gut mucosa and then disseminate, causing systemic infections associated with high mortality rates in immunocompromised individuals. It is unknown how L. monocytogenes traffic to the mesenteric lymph nodes, which represent an important bottleneck for systemic spread. In addition, little is known about the gastrointestinal stage of infection due to the general resistance of mice to oral infection with L. monocytogenes. Our laboratory developed a novel foodborne mouse model of listeriosis utilizing a murinized strain of L. monocytogenes to investigate the gastrointestinal stage …

Novel Role Of Prostate Apoptosis Response-4 Tumor Suppressor In B-Cell Chronic Lymphocytic Leukemia, Mary Kathryn Mckenna

Theses and Dissertations--Microbiology, Immunology, and Molecular Genetics

Chronic Lymphocytic Leukemia (CLL) is defined by the accumulation of clonally expanded CD5+ and CD19+ B lymphocytes in blood and secondary lymphoid organs with impaired apoptotic mechanisms. CLL represents one third of all leukemia cases with an average age of 72 years at diagnosis making it the most common adult leukemia. The Eµ-Tcl1 mouse serves as an excellent model to study the development of CLL as they progress to a CLL like disease by 9-14 months of age, due to overexpression of an oncogene, T cell Leukemia 1(Tcl1), specifically in B cells through the Ig VH promoter and Eµ enhancer …

Social Determinants Of Health And Disparities In Outcomes Related To Cardiovascular Health In Vulnerable Populations, Jennifer L. Miller

Theses and Dissertations--Pharmacy

This thesis aimed to elucidate the demographic characteristics associated with elevated or reduced rates of pneumococcal conjugate 13 (PCV13) vaccination.

A retrospective cohort study was performed using the Truven Health MarketScan® Database. Three cohorts were created corresponding to populations for which the CDC recommends PCV13 vaccination. Cohort 1: children < 36 months of age. Cohort 2: adults 19-64 years of age with high infection risk. Cohort 3: adults > 65 years of age. Odds of having a PCV13 claim were calculated for each cohort.

For Cohort 1, 78% out of a total of 353,214 subjects had a sufficient number of PCV13 doses to meet CDC recommendations. For Cohort 2, 3.7% out of a total of 673,157 subjects had a PCV13 …

Effects Of In Utero Nicotine Exposure On Immune Cell Disposition After P. Aeruginosa Lung Infection, Nayon Kang

Theses and Dissertations--Pharmacy

Current smoking cessation guidelines recommend nicotine replacement therapy (NRT) to assist pregnant smokers to quit, but this is without strong evidence for effectiveness and safety. Nicotine, the main addictive component of tobacco, is known to exert physiological effects by binding to its receptor, the nicotinic acetylcholine receptor (nAChR). Recent studies have identified the presence of nAChRs in non-neuronal cells, and in macrophages, functional alteration upon stimulation with nicotine has been documented.

To understand the impact of in utero nicotine exposure on various immune cell disposition and function, we designed preliminary studies using an in vivo model of P. aeruginosa infection. …

Analysis Of Humoral Immune Responses In Horses With Equine Protozoal Myeloencephalitis, Catherine-Jane Angwin

Theses and Dissertations--Veterinary Science

Equine protozoal myeloencephalitis (EPM), caused by the protozoan parasite Sarcocystis neurona, is one of the most important neurological diseases of horses in the Americas. While seroprevalence of S. neurona in horses is high, clinical manifestation of EPM occurs in less than 1% of infected horses. Factors governing the occurrence and severity of EPM are largely unknown, although horse immunity might play an important role in clinical outcome. We hypothesize that EPM occurs due to an aberrant immune response, which will be discernable in the equine IgG subisotypes a, b, and (T) that recognize S. neurona in infected diseased horses versus …

Lymphocyte-Mediated Inflamm-Aging In The Horse, Melissa Hope Siard

Theses and Dissertations--Veterinary Science

Senior horses (≥20 years) exhibit inflamm-aging, or chronic, low-grade inflammation that occurs systemically with aging, similarly to humans. Inflamm-aging has previously been characterized in the horse in circulation as well as specifically being mediated by lymphocytes and monocytes. In humans, inflamm-aging has been associated with increased morbidity and mortality. However, in the horse, relatively little about inflamm-aging is known regarding clinical effects or factors influencing severity. The contribution of lymphocytes to inflamm-aging of senior horses was examined, specifically through determining the relationships of inflamm-aging with various other health parameters, effects of seasonality, and the extent to which inflamm-aging can be …

Altitude- And Sex-Specific Variation In Roosting Ecology And Thermoregulation Of Myotis Lucifugus In Yellowstone National Park, Alexandra C. Slusher

Theses and Dissertations--Forestry and Natural Resources

Fifty-nine female and six male little brown myotis (Myotis lucifugus) were radio-tagged during the summers of 2012, 2013, 2014, and 2015 in Yellowstone National Park. The grand models for daily maximum skin temperature (F_98,154 = 1.55, P = 0.007), daily minimum skin temperature (F_98,154 = 1.33, P = 0.05), and daily variation in skin temperature (F_98,154 = 1.56, P = 0.006) were significant across roost type and reproductive condition class for adult females. Roosts were classified into Types A (warmest roosts), B (roosts with largest daily temperature variance), and C (stable and cool roosts) depending …

Evolution Of Equine Arteritis Virus During Persistent Infection In The Reproductive Tract Of The Stallion And The Male Donkey, Bora Nam

Theses and Dissertations--Veterinary Science

Equine arteritis virus (EAV) establishes persistent infection in the stallion reproductive tract, and the carrier stallion continues to shed virus in semen for weeks to years or lifelong. The objective of this study was to elucidate the intra-host evolution of EAV during persistent infection in stallions. Seven EAV seronegative stallions were experimentally infected with EAV KY84 strain and followed for 726 days post-infection, and sequential clinical samples including semen were collected for virus isolation and next-generation sequencing (NGS). In addition, archived sequential semen samples from two stallions that were naturally infected with EAV KY84 for a long-period (up to 10 …

Evaluation Of Pyriproxyfen Applied In Barrier Sprays For Mosquito Suppression, Andrea Glenn Skiles

Theses and Dissertations--Entomology

Despite advances in mosquito management, mosquito-borne disease in the United States is still of relevant public health concern and vector control is a top priority in preventing transmission of pathogens. Insecticide barrier sprays have become a common tool for suppression of mosquitoes in single-homeowner backyards. The application of the synthetic pyrethroid, lambda-cyhalothrin to perimeter vegetation with a backpack sprayer has been shown to significantly suppress mosquito levels for around 6 weeks. In an attempt to lengthen the effective duration of treatment, the IGR, pyriproxyfen, was added to a backpack mist blower with lambda-cyhalothrin, as adult mosquitoes exposed to pyriproxyfen have …
