Identifying Predictors For Inflammation-Induced Preterm Birth: A Murine Study, Tzu Ning Liu Bs, Jose Galaz Md, Nardhy Gomez-Lopez Phd

Medical Student Research Symposium

Introduction: Preterm birth is the leading cause of neonatal morbidity and mortality worldwide. A large proportion of preterm deliveries is affected by intra-amniotic inflammation, which can occur in the presence (intra-amniotic infection) or absence (sterile intra-amniotic inflammation) of microbes. Studies have shown an association between intra-amniotic inflammation, cervical shortening, and changes in the cervicovaginal microbiome. However, their causal relationships are unknown. This study aims to determine the causality of intra-amniotic inflammation, cervical shortening, and cervicovaginal microbiome alterations.

Methods: Pregnant C57BL/6 dams received an ultrasound-guided intra-amniotic injection of an endotoxin lipopolysaccharide (LPS) or the alarmin interleukin-1 alpha (IL-1 alpha) on 16.5 …

Faculty, Staff and Students Publications

BACKGROUND: COPA syndrome is a rare autoimmune disease, demonstrating an autosomal dominant inheritance pattern with variable penetration that occurs more frequently in females than males. This disease manifests in childhood as pulmonary hemorrhage, arthritis, and renal disease.

CASE: We present a case of obstetric management of a 20-year-old nulligravida patient with a diagnosis of COPA syndrome. Her case was further complicated by multiple antepartum admissions for hypoxemia and a complex psychosocial history of substance use. On her first antepartum admission, rheumatology recommended management with hydroxychloroquine, inhaled corticosteroids (budesonide), and bronchodilators (albuterol inhaler) as needed. On admission for induction of labor, …

Genital Chlamydia Infection Is Influenced By The Female Sex Hormones Estrogen And Progesterone In Vivo, Amy Gail Gravitte

Electronic Theses and Dissertations

Chlamydia is the most common bacterial sexually transmitted infection in the United States and worldwide. It often goes unnoticed due to lack of symptoms and left untreated it can ascend the female genital tract to cause sequelae like pelvic inflammatory disease and irreversible tubal infertility. In reproductive-aged women, female sex hormones estrogen (E2) and progesterone (P4) concentrations fluctuate during the menstrual cycle and are influenced by hormonal contraceptives and hormone replacement therapy. E2 and P4 influence genital Chlamydia infection in women and mice, but these multifactorial interactions are not entirely mapped out. The complex interplay of E2 and P4 with …

Of the 85 SARS-CoV-2–positive participants, 67 (79%) had no COVID-19 symptoms at the time of routine COVID-19 admission testing, 14 (16%) reported mild COVID-19 symptoms, and 4 (5%) presented …

The Effects Of Progesterone Induced Blocking Factor And 17-Hydroxyprogesterone Caproate On The Pathophysiology Of Preeclampsia, Kyleigh M. Comley

Honors Theses

Preeclampsia (PE) is responsible for about 20% of the 13 million preterm births each year worldwide, including 100,000 cases annually in the United States. Despite being a leading cause of maternal and perinatal morbidity, the mechanisms of pathogenesis are still largely unknown. PE is progesterone deficient state characterized by hypertension, chronic immune activation, endothelial dysfunction and severe forms can lead to seizures. Treatment of seizures includes the administration of magnesium sulfate (MgSO4) though not all PE patients are responsive, and it does not decrease PE-associated hypertension. To resolve these conditions, PE patients are delivered early thereby making PE the leading …

Targeting Epigenetic Mechanisms In Endometriosis, Sarah Elizabeth Brunty

Theses, Dissertations and Capstones

Endometriosis is a complex and elusive gynecological disease in which the inner lining of the uterus grows in locations outside of the uterus and forms lesions. It is known to affect 1 in 9 women of reproductive age worldwide. Symptoms of endometriosis include severe pain, heavy periods, and infertility. While multiple theories of origin exist, none fully encompass all aspects of the disease, although all theories agree that this is an inflammation-driven disease. Due to this, many researchers are turning towards epigenetics to explain the initiation and progression of endometriosis. However, what is causing these epigenetic changes is still a …

Contraceptive Methods In The United States: The Question Of Abortive Mechanisms, Tara Ferenczy

Senior Honors Theses

This thesis reviews the many methods of contraception available in the United States. Although society’s understanding of women’s health has become a major topic, there is still a significant deficit of information regarding how the accessible methods affect women’s bodies, specifically reproductive tissue. The thesis analyzes numerous contraceptive options focusing specifically on the mechanisms of action to determine whether options have abortifacient properties so that readers may develop educated opinions regarding medical and ethical uses. Information involving strengths and limitations of each technique and the effects on both the female body and the reproductive material assist in understanding the process …

An Investigation Of Treatments For The Prevention Of Metabolic Complications For Women Suffering From Polycystic Ovarian Syndrome: Diet, Exercise, Weight Reduction And Herbal Remedies, Brenda Martinez-Puente

Nursing | Senior Theses

The purpose of this research study is to compare the views of traditional versus alternative treatments available to women with Polycystic Ovarian Syndrome (PCOS) suffering from metabolic complications. Alternative treatments include diet, exercise, herbal remedies, or any combination of the three. Pharmacological interventions for the conditions associated with PCOS such as metformin, used to control glucose levels, and clomiphene, used to treat infertility. Through the literature review, articles show herbs and plant products to have similar mechanisms of actions as the pharmacological interventions, but with less side effects. For example, cinnamon was shown to increase insulin sensitivity and pomegranate juice …

The Evil Twin: The Case Of Heterotopic Pregnancy, Rashmi Jadhav, Vegas Brown, Gabriel Cabrera

West Florida Division GME Research Day 2020

• Heterotopic pregnancy occurs in about 1 in 30,000 naturally conceived pregnancies (5). The risk rises 1-3% for pregnancies occurring through assisted reproductive technologies (ART) (1).
• Isolated ectopic pregnancy affects an average of 1 in every 150 live births (1).

Endometriosis: The Etiology And Recommended Treatment, Amanda Lovell, Kasie Bellmann, Kelsey Fink, Jessica Beck, Michelle Musser

Pharmacy and Wellness Review

Endometriosis is a gynecological condition that occurs in women between the ages of 15 and 49 years, in which endometrial cells grow outside the uterus. Normally, endometrial cells form the endometrium and respond to hormones throughout the menstrual cycle, but when endometrial cells are located outside the endometrium, painful bleeding and other side effects may occur. Treatment of endometriosis is usually symptomatic relief, including the use of oral contraceptives and other hormone replacement options, as well as non-steroidal anti-inflammatory drugs. To ensure that patients receive the appropriate treatment for this condition, pharmacists should be able to recognize the signs and …

The Role Of Non-Neuronal Acetylcholine In Urogenital Chlamydial Infection, Jessica R. Lockhart

Electronic Theses and Dissertations

Chlamydia trachomatiscauses a bacterial sexually transmitted infection, Chlamydia, that is often chronic and casues reproductive complications in women. We hypothesized that Chlamydia infection increases local acetylcholine (ACh) production, which regulates the host’s inflammatory response to the infection. Female mice infected with C. muridarumwere sacrificed at days 3, 9, 15, and 21 post-infection, genital tract tissues harvested, and immunohistochemistry performed to enumerate ACh-producing cells. Infection increased the number of ACh-producing cells in cervical tissue at days 3,15, and 21 post-infection (pi), uterine tissue at day 3 and 9 pi, and ovarian tissue day 3, 15, and 21 pi. These …

Investigating AMPK signalling regulation of autophagy in a model of ovarian tumour dormancy

Jeremi Laski and Trevor G. Shepherd

Background:

Ovarian cancer is the most deadly gynecologic malignancy in women. A particular subset of this disease, epithelial ovarian cancer (EOC), is responsible for over 70% of all diagnosed ovarian cancer cases, yet the mechanisms governing disease progression are poorly understood. One of the unique hallmarks of EOC metastasis lies in the process of spheroid formation, whereby tumour cells aggregate into larger 3D structures. These EOC spheroids have been shown to be metabolically dormant, while concurrently up-regulating autophagy (cellular waste …

Chat Expression In Chlamydia Muridarum-Infected Female Murine Genital Tract, Hallie Sartain

Undergraduate Honors Theses

Chlamydia trachomatis is the most prevalent agent of bacterial sexually transmitted infections in the world. However, a profuse number of cases are unreported, as the infection is often asymptomatic. Sequelae such as pelvic inflammatory disease, an increased risk of cervical cancer, premature birth, and perinatal infections in pregnant women can occur. Inflammation occurs in the body in response to infection or injury. Although inflammation can lead to some unwanted secondary effects, such as pain, it serves to return the body to homeostasis by restoring injured tissues and eliminating pathogens. One recently identified connection between the central nervous system and the …

Saha Cardiovascular Research Center Faculty Publications

Introduction

Preeclampsia (PE) is a gestational disorder, manifested in the second half of pregnancy by maternal hypertension, proteinuria and generalized edema. PE is a major cause of maternal and fetal morbidity and mortality, accounting for nearly 40% of all premature births worldwide. Bioactive sphingolipids are emerging as key molecules involved in etiopathogenesis of PE, characterized by maternal angiogenic imbalance and symptoms of metabolic syndrome. The aim of this study was to compare the cross-gestational profile of circulating bioactive sphingolipids in maternal plasma from preeclamptic (PE) versus normotensive control (CTL) subjects with the goal of identifying sphingolipids as candidate first trimester …

Vulvodynia; An Under-Recognized Disease, Simona Roxana Georgescu, Cristina I. Mitran, Mădălina I. Mitran, Maria I. Sârbu, Mircea Tampa

Journal of Mind and Medical Sciences

Vulvodynia is a chronic condition which affects an increasing number of women; it presents currently an incidence that is higher than had previously been estimated. Regarding pathogenesis, several (hormonal, infectious, inflammatory and psychological) factors have been proposed, but vulvodynia etiology remains still unclear. This disorder is a multifactorial condition with a significant impact on the patient’s quality of life, yet is difficult to diagnose (an under-estimated/ under-recognized affection). Certain medical investigations are required in order to exclude other diseases (the diagnosis of vulvodynia being one of exclusion), but anamnesis and physical examination are essential steps in the diagnosis.

Although many …

Genetic And Epigenetic Mechanisms Of Complex Reproductive Disorders, Bhavi P. Modi

Theses and Dissertations

Common, complex disorders are polygenic and multifactorial traits representing interactions between environmental, genetic and epigenetic risk factors. More often than not, contributions of these risk factors have been studied individually and this is especially true for complex reproductive traits where application of genomic technologies has been challenging and slow to progress. This thesis explores the potential of genetic and epigenetic components contributing to a better understanding of the biological pathways underlying disease risk in two specific female complex reproductive traits - polycystic ovary syndrome (PCOS) and preterm premature rupture of membranes (PPROM). The PCOS projects focus on characterization of a …

The Hormonal Regulation Of The Claudin Genes In The Ovary, Sean Gadson, April Binder, Kenneth Korach, Katherine Hamilton

All Master's Theses

The ovary is a dynamic organ that responds to many hormonal signals. When these hormonal signals are disrupted, ovarian dysfunction can occur. One such example is Polycystic Ovarian Syndrome (PCOS). PCOS patients suffer from high levels of testosterone. Excess testosterone may misregulate genes in the ovary and disrupt ovarian function. The Claudin (Cldn) 3 and Cldn11 genes have been shown to be regulated by androgens in the testis, while studies in ovarian cancer cells suggests a coregulatory mechanism for the expressions of Cldn3 and Cldn4 in the ovary. The objective of this study was to characterize the hormonal …

Polycystic Ovarian Syndrome, Tameka Todd

Nursing Student Class Projects (Formerly MSN)

The main goal of this project was to educate peers on the pathophysiology of a disease or disorder of choice. The topic to be discussed is Polycystic Ovarian Syndrome (PCOS). This topic was chosen based on personal interest in women’s health issues. PCOS is a metabolic disease affecting 5-10 percent of women of childbearing age (Morgan, 2013). Characteristics of PCOS include enlarged ovaries consisting of multiple small cysts surrounding the outer ovary, with unknown cause (Morgan, 2013). Leading to the ovaries producing an increased amount of androgen (male hormones) (Morgan, 2013).

Identification Of Transcription Factors Gzf3, Rfx1, Orf19.3928 As Being Implicated In Candida-Bacterial Interactions., Joni Watson

Undergraduate Honors Theses

Candida albicans is an opportunistic pathogen that is present in the normal flora in a majority of individuals. One key factor in C. albicans virulence is the ability to change its morphology from yeast to an elongated or hyphal form. The regulation of this morphogenesis relies in part upon quorum sensing (QS) molecules. C. albicans often exists as part of a mixed culture alongside other microbes and is influenced by their presence as well as the presence of QS molecules that they produce. In this study, a library of diploid homozygous transcriptional regulator knockout (TRKO) mutants were screened to identify …

The Mucosal Expression Pattern Of Interferon-Ε In Rhesus Macaques, Andrew Demers, Guobin Kang, Fangrui Ma, Wuxun Lu, Zhe Yuan, Yue Li, Mark Lewis, Edmundo N. Kraiselburd, Luis Montaner, Qingsheng Li

Qingsheng Li Publications

Type I IFNs play an important role in innate and adaptive immunity against viral infections. A novel type I IFN, namely IFN-ε, which can protect against vaginal transmission of HSV2 and Chlamydia muridarum bacterial infection, has been described in mice and humans. Nevertheless, the principle cell type and the expression pattern of IFN-ε in tissues remain uncertain. In addition, the expression of IFN-ε in Indian rhesus macaques (Macaca mulatta) has not been reported. Here, we analyzed IFN-ε expression in multiple mucosal sites of uninfected or SIV-infected Indian rhesus macaques using IHCS. We report for the first time the …

Characterization Of The Sigma Factor Proteins And The Dna Binding Protein Euo Of Chlamydia, Cory L. Blackwell

Theses and Dissertations (ETD)

Chlamydia spp. are prokaryotic obligate intracellular pathogens with a unique, biphasic developmental cycle in which an infectious, extracellular form termed the elementary body (EB) interconverts with a metabolically active intracellular reticulate body (RB) within host cells. Subsets of genes are differentially expressed during the developmental cycle, and these genes are believed to be responsible for the transitions between the EB and RB forms. The goal of these studies was to explore two potential mechanisms that may function in regulating developmental cycle stage‑specific gene expression in chlamydiae: a cascade of sigma factor expression and the binding of the early stage protein …

Novel Binding Domains Mediate Binding Of Hpv 16 E6 To Fadd And Procaspase 8, Sandy S. Tungteakkhun

Loma Linda University Electronic Theses, Dissertations & Projects

To evade the host response to infection, viruses have developed means to survive and propagate. HPV 16, a causative agent of cervical cancer and of some cases of oropharyngeal cancers, is one example. We have reported that the early viral protein E6 binds to proteins necessary for propagation of the apoptotic signal following receptor/ligand interactions, such as those mediated by FADD DED and procaspase 8 DED. E6 expression leads to the dose-dependent accelerated degradation of FADD and the protection of E6-expressing cells from Fas-induced apoptosis. Surprisingly, the splice isoforms of E6, E6_large and E6*, affect the stability of procaspase …
