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 …

Human Oocytes And Embryos Viewed By Time-Lapse Videography, And The Development Of An Embryo Deselection Model, Yanhe Liu

Theses: Doctorates and Masters

Despite its wide application today, in vitro fertilization (IVF) treatment continues to have relatively low efficacy, largely due to inaccuracy in selecting the best quality embryo(s) from the cohort for transfer. Novel methodologies for improved selection are being developed, and time-lapse observation of human embryos is gaining increasing popularity due to the more detailed morphokinetic information obtained plus uninterrupted culture conditions. The morphokinetic information enables the use of quantitative timings in developmental milestones of embryos and qualitative measures of abnormal biological events, to assist embryo selection/deselection. This project aimed to identify current limitations in the use of such measures and …

Differential Expression Of Mrna Encoding Cytokines And Chemokines In The Reproductive Tract After Infection Of Mice With Chlamydia Trachomatis, Katheryn L. Cerny, Maranda Van Fleet, Anatoly Slepenkin, Ellena M. Peterson, Phillip J. Bridges

Animal and Food Sciences Faculty Publications

Infection with Chlamydia trachomatis targets epithelial cells within the genital tract which respond by secreting chemokines and cytokines. Persistent inflammation can lead to fibrosis, tubal infertility and/or ectopic pregnancy; many infections are asymptomatic. Most studies have investigated the inflammatory response in the initial stages of infection, less is known about the later stages of infection, especially with a low, potentially asymptomatic, bacterial load. Our objective was to determine the inflammatory mediators involved in clearance of low-grade infection and the potential involvement in chronic inflammation. Six to eight week old C3H/HeJ mice were pretreated with 2.5 mg medroxyprogesterone acetate on day …

Implantable Device For Wireless Regulation Of The Bladder Through Pelvic Nerve Stimulation, Kelsey C. Bayer, Chris Quinkert, Pedro Irazoqui

The Summer Undergraduate Research Fellowship (SURF) Symposium

Urinary incontinence (UI) is the involuntarily urination that usually effects older people or is the result of an injury. UI affects more than eleven million people and the cost of incontinence management in the United States in 2000 was $19.5 billion. Where conventional physical therapies have failed, pelvic nerve stimulation is a promising form of regulating the bladder long term. Piezoresistive pressure sensors consist of two variable resistance values and two known resistance values that are represented on a daughterboard. This unknown resistance represents the change in pressure. The filling and voiding of the bladder was characterized through acute surgeries. …

Exploring Egr-1 As A Master Regulator Of Prostate Field Cancerization, Kristin Gabriel, Marco Bisoffi

Student Scholar Symposium Abstracts and Posters

Field cancerization denotes the presence of molecular aberrations (genetic, epigenetic, biochemical) in structurally intact cells residing in histologically normal tissues adjacent to tumors. Markers of field cancerization in prostate tissues have the potential to improve the clinical management of this malignancy through their potential to act as indicators of early disease and to serve as molecular targets for early intervention. However, for this, a detailed understanding of the functional pathways underlying field cancerization is necessary. We have recently identified four protein markers of prostate field cancerization, i.e. the key transcription factor early growth response 1 (EGR-1), the lipogenic enzyme fatty …

Prostate Field Cancerization – Thinking Outside The Tumor, Dor Shoshan

Student Scholar Symposium Abstracts and Posters

Analysis of tumor adjacent tissue is assumed to reveal a temporal record of molecular pathways that define oncogenesis. The present study determines expression of the key transcription factor and potential marker of field cancerization early growth response 1 (EGR-1) in human prostate tissues derived from prostatectomies and biopsies. Expression was detected using immunofluorescence and quantified using ImageJ software. Accordingly, EGR-1 expression was similar in cancerous and in histologically normal adjacent tissues from prostatectomy and biopsy specimens. EGR-1 could be exploited as pre-surgical disease indicator in false negative biopsies, identify areas of repeat biopsy, and add molecular information to surgical margins.

Effect Of Curcumin Analog Ca27 On Androgen Receptor Translocation In Prostate Cancer Cells, Lijah Vann Gardner

Student Scholar Symposium Abstracts and Posters

The androgen receptor (AR) plays an essential role in promoting the development and progression of metastatic prostate cancer and represents an important molecular target for therapeutic intervention. We have recently described a series of synthetic analogs of the natural product diferuloylmethane (curcumin), some of which induce the down-regulation of AR expression in prostate cancer cells by an as yet largely unknown mechanism of action. While such analogs may in the long term be lead structures for the development of therapeutic drugs, we hypothesize here that they represent ideal molecular probes to identify the mechanism(s) of action for AR down-regulation. We …

Marriage and Family Therapy Faculty Articles and Research

STUDY QUESTION What are the levels of awareness regarding female fertility and the intentions and attitudes towards parenthood among Chinese university students in Hong Kong compared with their counterparts in the West?

SUMMARY ANSWER Chinese university students in Hong Kong were similarly over-optimistic about the age-related fertility decline, although they were less inclined to have children and undergo fertility treatment compared with their Western counterparts.

WHAT IS KNOWN ALREADY Past studies of highly educated young adults in Europe and the USA have found that they are not sufficiently aware of the age-related decline in female fertility, and falsely believe that …

La Cesárea Y El Parto Natural: Las Opiniones De Profesionales De La Salud En La Provincia De Buenos Aires / Cesarean Section And Natural Birth: The Opinions Of Health Provinces In The Province Of Buenos Aires, Jacqueline Chipkin

Independent Study Project (ISP) Collection

Introduction: The ways in which women of society give birth have the power to influence maternal-infant health and shape the economy of the healthcare system. Today, the rates of cesarean sections are increasing throughout the world. In Argentina, on average, more than 35% of pregnant women received cesarean sections in 2008, with large differences observed in the rates between the public and private health sectors. The World Health Organization (WHO) has established that healthcare systems should only employ a cesarean section if labor cannot progress safely. According to this standard, the organization estimates that cesarean sections should only be utilized …

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 …

Cryptorchidism And Infertility In Rats With Targeted Disruption Of The Adamts16 Locus, Shakila Abdul-Majeed, Blair Mell, Surya M. Nauli, Bina Joe

Pharmacy Faculty Articles and Research

A Disintegrin And Metalloproteinase with ThromboSpondin motifs16 (ADAMTS-16) is a member of a family of metalloproteinases. Using a novel zinc-finger nuclease based gene-edited rat model harboring a targeted mutation of the Adamts16 locus, we previously reported this gene to be linked to blood pressure regulation. Here we document our observation with this model that Adamts16 is essential for normal development of the testis. Absence of Adamts16 in the homozygous Adamts16(mutant) males resulted in cryptorchidism and male sterility. Heterozygous Adamts16(mutant) males were normal, indicating that this is a recessive trait. Testes of homozygous Adamts16(mutant) males were significantly smaller with significant histological …

Maternal Biomarkers Of Endothelial Dysfunction And Preterm Delivery, Xinhua Chen, Theresa O Scholl

Rowan-Virtua School of Osteopathic Medicine Departmental Research

BACKGROUND: Endothelial dysfunction is key to the development of atherosclerosis. Preterm delivery foreshadows later maternal cardiovascular disease (CVD), but it is not known if endothelial dysfunction also occurs. We prospectively measured circulating biomarkers of endothelial dysfunction in pregnant women with preterm or term delivery.

METHODS: We conducted a case-control study nested within a large prospective epidemiological study of young, generally healthy pregnant women. Women who delivered preterm (gestation, n = 240) and controls who delivered at term (n = 439) were included. Pregnancies complicated by preeclampsia were analyzed separately. Circulating endothelial dysfunction biomarkers included soluble intercellular adhesion molecule-1 (sICAM-1), vascular …

Anti-Müllerian Hormone In Stallions And Mares: Physiological Variations, Clinical Applications, And Molecular Aspects, Anthony N.J. Claes

Theses and Dissertations--Veterinary Science

Anti-Müllerian hormone (AMH) is a homodimeric glycoprotein that is best known for its role in regression of the Müllerian duct in the male fetus. Accumulating evidence indicates that AMH also has an important role during different physiological processes after birth. In contrast to other species, relatively little is known about AMH in the horse. In chapter one, developmental and seasonal changes in serum AMH concentrations in male horses were determined, and the use of AMH for determination of retained cryptorchid testes was established. In chapter two, the interrelationship between plasma AMH concentrations, antral follicle counts (AFC), and age in mares …

Jordanian Ethical Perceptions Of Preimplantation Genetic Diagnosis, Sarah C. Miller

Independent Study Project (ISP) Collection

Preimplantation Genetic Diagnosis (PGD) is a procedure that can be done during In Vitro Fertilization (IVF), involving genetic and chromosomal screening of fertilized embryos prior to implantation into a woman’s uterus. After PGD, only the embryos possessing the desired characteristics are implanted, while the other embryos are frozen for future use, or discarded. PGD is used for family balancing (gender selection for balancing the gender dynamic within a family), gender selection to screen out sex-linked diseases, or a broader genetic screening for diseases known to be present in the patient’s family history.

Many ethical questions have been raised about PGD, …

Research Brief: "Women Veterans’ Reproductive Health Preferences And Experiences: A Focus Group Analysis", Institute For Veterans And Military Families At Syracuse University

Institute for Veterans and Military Families

This brief is about the experiences and preferences for reproductive health care services among female veterans. In policy and practice, the VA should expand communication efforts to ensure that female veterans know the reproductive health services that are available to them, include more advanced fertility care, and widen the range of healthcare choices available to veteran women; the VA should look into covering healthcare for newborns and expanding access to infertility services. Suggestions for future research include using a random, nationally representative sample of female veterans, and looking at gender discrimination's potential impact on their quality of care.

Resource Availability, Mortality And Fertility: A Path Analytic Approach To Global Life History Variation, Mark A. Caudell, Robert J. Quinlan

Human Biology Open Access Pre-Prints

Humans exhibit considerable diversity in timing and rate of reproduction. Life history theory suggests that ecological cues of resource richness and survival probabilities shape human phenotypes across populations. Populations experiencing high extrinsic mortality due to uncertainty in resources should exhibit faster life histories. Here we use a path analytic approach informed by life history theory to model the multiple pathways between resources, mortality rates, and reproductive behavior in 191 countries. Resources that account for the most variance in population mortality rates are predicted to explain the most variance in total fertility rates. Results indicate that resources (e.g., calories, sanitation, education, …

Do Photoperiodic Changes In Melatonin Secretion Detrimentally Affect The Female Reproductive Cycle?, Riki Szlafrok

The Science Journal of the Lander College of Arts and Sciences

Melatonin, better known as "the hormone of darkness," is secreted by the pineal gland during the night and helps us fall asleep. Because its internal regulation depends on light, melatonin is part of chronobiology, the study of biological mechanisms and their adaptations to lunar and solar related rhythms (Klein et al. 1991). Therefore, photoperiod changes greatly impact melatonin concentration, influencing changes in neuronal and hormonal mechanisms of the photo neuro-endocrine systems, namely reproduction. Research has shown that a disruption in the circadian rhythm of melatonin due to photoperiod changes detrimentally affects the rhythmic function of the female reproductive cycle. Research …
