Inflammatory Gene Expression In Women Diagnosed With Polycystic Ovarian Syndrome, Myles K. Taylor
Inflammatory Gene Expression In Women Diagnosed With Polycystic Ovarian Syndrome, Myles K. Taylor
Electronic Theses & Dissertations
Polycystic ovarian syndrome (PCOS) is a common endocrine disorder in women of reproductive age. The pathophysiology of PCOS has conventionally thought to originate from androgen excess. However, recent evidence suggests that androgen excess is a downstream consequence to inflammatory dysregulation and subsequent metabolic abnormalities. Inflammatory mRNA gene expression of TNFa and IL-1ß in mononuclear cells isolated from women diagnosed with PCOS was explored using qPCR. Additionally, the correlations between body mass index (BMI) and fasting glucose on mRNA expression of TNFa and IL-1ß were explored. mRNA expression of both TNFa and IL-1ß were found to be significantly higher in PCOS …
Phenotypic Analysis And Localization Of Leukocytes At The Site Of Intradermal Injection Of Phytohemagglutinin In Chickens, Kallie Alyce Sullivan
Phenotypic Analysis And Localization Of Leukocytes At The Site Of Intradermal Injection Of Phytohemagglutinin In Chickens, Kallie Alyce Sullivan
Graduate Theses and Dissertations
Phytohemagglutinin (PHA) is commonly used to gain insight into an individual’s cellular immuno-competence. PHA is typically injected intradermally (i.d.) into the skin (e.g. wing web) and the tissue swelling response is then monitored, whereby the extent of the swelling positively relates to the individual’s cellular immune system capabilities. Although i.d. injected PHA was shown to stimulate mononuclear cell- and basophil-infiltration to the site of injection, reports on temporal, qualitative and quantitative aspects of the local PHA response are limited. The objective of this study was to use the growing feather (GF) as a cutaneous test-site to assess and monitor the …
The Rodent Parvovirus H-1 And Its Potential In Combination With Tien Hsien Liquid As A Treatment For Breast Cancer, Hayley I. Spires
The Rodent Parvovirus H-1 And Its Potential In Combination With Tien Hsien Liquid As A Treatment For Breast Cancer, Hayley I. Spires
Selected Honors Theses
Breast cancer is responsible for 12% of cancer diagnoses each year, and it is the leading cause of cancer-related mortality in women worldwide. Current treatments have provided some success in combatting the disease but are not considered a final solution. The framework for how researchers approach cancer has continued to change, and this includes the introduction of oncolytic viruses as novel therapeutics for cancer. The rodent parvovirus H-1 has shown strong potential in clinical and subclinical trials, but its S phase dependency limits its usefulness against cancer stem cell populations. Tien Hsien Liquid is commerically available, nontoxic, and has shown …
Hiv Vaccines: Progress, Limitations And A Crispr/Cas9 Vaccine, Omar A. Garcia Martinez
Hiv Vaccines: Progress, Limitations And A Crispr/Cas9 Vaccine, Omar A. Garcia Martinez
Biology: Student Scholarship & Creative Works
ABSTRACT: The HIV-1 pandemic continues to thrive due to ineffective HIV-1 vaccines. Historically, the world’s most infectious diseases, such as polio and smallpox, have been eradicated or have come close to eradication due to the advent of effective vaccines. Highly active antiretroviral therapy is able to delay the onset of AIDS but can neither rid the body of HIV-1 proviral DNA nor prevent further transmission. A prophylactic vaccine that prevents the various mechanisms HIV-1 has to evade and attack our immune system is needed to end the HIV-1 pandemic. Recent advances in engineered nuclease systems, like the CRISPR/Cas9 system, have …
Defining The Role Of Interferon Regulatory Factor 4 In Chronic Lymphocytic Leukemia., Vipul Shukla
Defining The Role Of Interferon Regulatory Factor 4 In Chronic Lymphocytic Leukemia., Vipul Shukla
Theses & Dissertations
Chronic Lymphocytic Leukemia (CLL) represents the most common adult leukemia in the Western hemisphere. Despite considerable progress in our current understanding of CLL, this disease remains incurable and the molecular events underlying the complex pathogenesis of CLL are not fully elucidated. Interferon Regulatory Factor 4 (IRF4) belongs to the IRF superfamily of transcription factors that has been shown to play critical roles at multiple stages of B cell development. Interestingly, a Genome Wide Association Study identified Single Nucleotide Polymorphism (SNP) mediated IRF4 down regulation, as a major predisposing genetic event during the development of CLL. However, whether low levels of …
Optimization Of Expression And Purification Of The Rig-I-Like-Receptor, Lgp2, Srinath-Reddi Pingle
Optimization Of Expression And Purification Of The Rig-I-Like-Receptor, Lgp2, Srinath-Reddi Pingle
University Scholar Projects
The innate immune system is one of the first lines of defense against pathogens. RIG-I like receptors (RLRs) are a class of cytosolic receptors that recognize molecular patterns of invading pathogens and signal for downstream interferon induction. The RLR family consists of three proteins, RIG-I, MDA5, and LGP2. MDA5 and LGP2 work together to recognize and bind long viral dsRNA. LGP2 is thought to regulate MDA5 activation, but little is understood about this process. Characterization of the mechanism of action of these receptors requires careful biophysical and biochemical analyses. I have developed expression and purification of methods LGP2 and MDA5 …
Comparison Of Anti-Pneumococcal Functions Of Native And Modified Forms Of C-Reactive Protein, Donald Neba Ngwa
Comparison Of Anti-Pneumococcal Functions Of Native And Modified Forms Of C-Reactive Protein, Donald Neba Ngwa
Electronic Theses and Dissertations
The anti-pneumococcal function of native C-reactive protein (CRP) involves its binding to phosphocholine molecules present on Streptococcus pneumoniae and subsequent activation of the complement system. However, when pneumococci recruit complement inhibitory protein factor H on their surface, they escape complement attack. Non-native forms of CRP have been shown to bind immobilized factor H. Accordingly, we hypothesized that modified CRP would bind to factor H on pneumococci, masking its complement inhibitory activity, allowing native CRP to exert its anti-pneumococcal function. As reported previously, native CRP protected mice from lethal pneumococcal infection when injected 30 minutes before infection but not when injected …
Preeclampsia: The Roles Of Acute Inflammation And Intrauterine Stress, Nicholas Parchim
Preeclampsia: The Roles Of Acute Inflammation And Intrauterine Stress, Nicholas Parchim
Dissertations and Theses (Open Access)
Preeclampsia (PE) is a severe, acute disease of pregnancy affecting approximately 8% of pregnant women after week 20 of gestation. PE is characterized by hypertension and renal damage reflected by proteinuria and has significant morbidity to both mother and fetus. Maternal symptoms range from headaches, nausea, edema, to visual changes, but once maternal symptoms present, damage to the fetus has begun. Mothers who progress untreated through the disease can also experience a condition called eclampsia characterized by seizure, coma, and, ultimately, death. PE-affected newborns experience features similar to prematurity—abnormal lung and renal development, intrauterine growth retardation (IUGR), and, possibly, fetal …
Investigating The Effects Of Increasing Anti-Ama1, Anti-Msp1, And Anti-Msp2 In Preventing Malaria Incidence, April Skipper
Investigating The Effects Of Increasing Anti-Ama1, Anti-Msp1, And Anti-Msp2 In Preventing Malaria Incidence, April Skipper
Selected Honors Theses
Malaria is a life-threatening illness that 3.2 billion people, half of the world's population, are at risk of contracting. In 2015, there were 214 million malaria cases and 438,000 deaths caused by the disease. It is caused by Plasmodium parasites which infect humans through the bite of the Anopheles mosquito. The four species of Plasmodium that are known to cause malaria are P. falciparum, P. vivax, P. ovale, P. malariae, and P. knowlesi. The symptoms of malaria greatly resemble symptoms of a common cold, so accurate diagnosis can be a challenge. Symptoms commonly include fever, headache, …
Investigating The Efficacy And Anti-Resistance Activity Of Fexinidazole In Conjunction With Eflornithine Against Trypanosoma Brucei For Treatment Of Human African Trypanosomiasis, Mercy Toma
Selected Honors Theses
Human African Trypanosomiasis (HAT) is one of 17 neglected tropical disease prioritized by the World Health Organization (WHO). Neglected tropical diseases are diseases which affect poor or developing countries and which do not get as much as attention as the ‘big three’: malaria, tuberculosis and HIV/AIDS. HAT specifically affects coutries in Sub-Saharan Africa and is caused by a parasitic protozoa, Trypanosoma brucei. There are two stages of HAT: the early haemolymphatic and late meningo-encephalitic stages. There are also two subtypes of the disease caused by either T. b. gambiense or T.b rhodesiense forms of the parasite. There are four drugs …
Automated Assessment Of Disease Progression In Acute Myeloid Leukemia By Probabilistic Analysis Of Flow Cytometry Data, Bartek Rajwa, Paul K. Wallace, Elizabeth A. Griffiths, Murat Dundar
Automated Assessment Of Disease Progression In Acute Myeloid Leukemia By Probabilistic Analysis Of Flow Cytometry Data, Bartek Rajwa, Paul K. Wallace, Elizabeth A. Griffiths, Murat Dundar
Bindley Publications
Objective: Flow cytometry (FC) is a widely acknowledged technology in diagnosis of acute myeloid leukemia (AML) and has been indispensable in determining progression of the disease. Although FC plays a key role as a post-therapy prognosticator and evaluator of therapeutic efficacy, the manual analysis of cytometry data is a barrier to optimization of reproducibility and objectivity. This study investigates the utility of our recently introduced non-parametric Bayesian framework in accurately predicting the direction of change in disease progression in AML patients using FC data. Methods: The highly flexible non-parametric Bayesian model based on the infinite mixture of infinite Gaussian …

Autoimmune vasculitis is an endothelial inflammatory disease that results from the deposition of immune-complexes (ICs) in blood vessels. The interaction between Fcgamma receptors (FcyRs) expressed on inflammatory cells with ICs is known to cause blood vessel damage. Hence, blocking the interaction of ICs and inflammatory cells is essential to prevent the IC-mediated blood vessel damage. Thus we tested if uncoupling the interaction of FcyRs and ICs prevents endothelium damage. Herein, we demonstrate that dimeric FcyR-Igs prevented nitric oxide (NO) mediated apoptosis of human umbilical vein endothelial cells (HUVECs) in an in vitro vasculitis model. Dimeric FcyR-Igs significantly inhibited the IC-induced …
How Compatible Is Cow’S Milk With The Human Immune System?, Mindy Knopfler
How Compatible Is Cow’S Milk With The Human Immune System?, Mindy Knopfler
The Science Journal of the Lander College of Arts and Sciences
Cow’s milk has been part of the human diet for at least 8,000 years and provides a rich source of proteins, lipids, vitamins, and minerals. Despite its longstanding importance in human nutrition, questions remain about how compatible cow’s milk is with our immune system. Cow’s milk allergy (CMA) is the most common form of food allergy in infants and children and cow’s milk has been implicated in a number of immune-mediated disorders. Reviewing current research obtained through Google Scholar and Touro’s library database on CMA and the potential role of cow’s milk in systemic inflammation and autoimmunity reveals a tangle …
Role Of Vav2 In Podocyte Inflammasome Activation And Glomerular Injury During Hyperhomocysteinemia, Sabena Conley
Role Of Vav2 In Podocyte Inflammasome Activation And Glomerular Injury During Hyperhomocysteinemia, Sabena Conley
Theses and Dissertations
Hyperhomocysteinemia (hHcys) is a widely known pathogenic factor in the progression of end-stage renal disease (ESRD) and it is also associated with an increased risk for injurious cardiovascular pathologies during ESRD. HHcys is linked to the formation and activation of the NOD-like receptor protein 3 (NLRP3) inflammasome, characterized as a critical early mechanism initiating the inflammatory response. NADPH oxidase (NOX)-derived reactive oxygen species (ROS) mediate the activation of the NLRP3 inflammasome in podocytes in response to elevated levels of homocysteine (Hcys) in vitro and in vivo. However, it remains unknown how NLRP3 inflammasome activation is triggered by NOX. The …
