Human Chorionic Gonadotropin Administration Is Associated With High Pregnancy Rates During Ovarian Stimulation And Timed Intercourse Or Intrauterine Insemination, Mohamed F. Mitwally, Sonya Abdel-Razeq, Robert F. Casper

Wayne State University Associated BioMed Central Scholarship

Abstract

Background

There are different factors that influence treatment outcome after ovarian stimulation and timed-intercourse or intrauterine insemination (IUI). After patient age, it has been suggested that timing of insemination in relation to ovulation is probably the most important variable affecting the success of treatment. The objective of this study is to study the value of human chorionic gonadotropin (hCG) administration and occurrence of luteinizing hormone (LH) surge in timing insemination on the treatment outcome after follicular monitoring with timed-intercourse or intrauterine insemination, with or without ovarian stimulation.

Methods

Retrospective analysis of 2000 consecutive completed treatment cycles (637 timed-intercourse and …

Testing The Effectiveness Of Integrating Community-Based Approaches For Encouraging Abandonment Of Female Genital Cutting Into Care's Reproductive Health Programs In Ethiopia And Kenya, Jane Chege, Ian Askew, Susan Igras, Jacinta Muteshi-Strachan

Reproductive Health

CARE International, with technical support from the Frontiers in Reproductive Health Program completed a study in Ethiopia and Kenya designed to test the effectiveness of education activities using behavior change communication (BCC) approaches and advocacy activities by religious and other key leaders to abandon female genital cutting (FGC). In Ethiopia, the increased knowledge of harmful FGC effects and human rights issues translated to a positive attitude in support of FGC abandonment and an intention not to cut their daughters in the future. In Kenya, the analysis indicated mixed results in attitude and intended behavior change.

Medicalization Of Female Genital Cutting Among The Abagusii In Nyanza Province, Kenya, Carolyne Njue, Ian Askew

Reproductive Health

This study sought to understand the role that health providers play in the medicalization of female genital cutting (FGC) among the Abagusii community in western Kenya, among whom the practice continues to be almost universal. Interviews with service providers and their clients revealed an overwhelming belief that FGC fulfills a traditional cultural obligation among the Abagusii, and that it limits a woman’s sexual desire and confers respect on girls. New approaches are needed within this community to present FGC as violating human rights and national laws, as well as threatening girls’ and women’s health. The study recommends measures such as …

Female Circumcision In Indonesia. Extent, Implications And Possible Interventions To Uphold Women's Health Rights, Meiwita P. Budiharsana, Lila Amaliah, Budi Utomo

Reproductive Health

In Indonesia, the practice of female circumcision (FC) has long existed, but information concerning where and how it is carried out has been limited. The specific aims of the study conducted by the Population Council Jakarta were to provide research-based information on FC customary practices and their socio-cultural determinants, and if possible, to assess any long-term physical and psychological consequences. Study findings indicate that in general Muslim communities support the continuation of FC practice, because they perceive it as both a societal custom and a religious duty. The report strongly recommends that key donor agencies pressure the Ministry of Health …

Transcriptional Inhibition Of Type I Collagen Gene Expression In Scleroderma Fibroblasts By The Antineoplastic Drug Ecteinascidin 743., Natalia Louneva, Biagio Saitta, David J Herrick, Sergio A. Jimenez

Department of Medicine Faculty Papers

We previously showed that COL1A1 expression is up-regulated at the transcriptional level in systemic sclerosis (SSc) fibroblasts and that the CCAAT-binding factor (CBF) is involved in this increased expression. Ecteinascidin 743 (ET-743) is a chemotherapeutic agent that binds with sequence specificity to the minor groove of DNA and inhibits CBF-mediated transcriptional activation of numerous genes. Therefore, we examined the effects of ET-743 on the increased COL1A1 expression in SSc fibroblasts. The drug caused a potent and dose-dependent inhibition of type I collagen biosynthesis, which reached 70-90% at 700 pM without affecting cell viability. The same drug concentration caused 60-80% reduction …

Topographical Expression Of Class Ia And Class Ii Phosphoinositide 3-Kinase Enzymes In Normal Human Tissues Is Consistent With A Role In Differentiation, Soha Salama El Sheikh, Jan Domin, Prakitpunthu Tomtitchong, Paul Abel, Gordon Stamp, El-Nasir Lalani

Department of Pathology and Laboratory Medicine

Background: Growth factor, cytokine and chemokine-induced activation of PI3K enzymes constitutes the start of a complex signalling cascade, which ultimately mediates cellular activities such as proliferation, differentiation, chemotaxis, survival, trafficking, and glucose homeostasis. The PI3K enzyme family is divided into 3 classes; class I (subdivided into IA and IB), class II (PI3K-C2α, PI3K-C2β and PI3K-C2γ) and class III PI3K. Expression of these enzymes in human tissue has not been clearly defined.

Methods: In this study, we analysed the immunohistochemical topographical expression profile of class IA (anti-p85 adaptor) and class II PI3K (PI3K-C2α and PI3K-C2β) enzymes in 104 formalin-fixed, paraffin embedded …

Sart Influences Sars Expression In Staphylococcus Aureus, Katherine A. Schmidt, Adhar C. Manna, Ambrose L. Cheung

Dartmouth Scholarship

Staphylococcus aureus is a gram-positive pathogen that is capable of expressing a variety of virulence proteins in response to environmental signals. Virulence protein expression in S. aureus is controlled by a network of regulatory loci including sarA and agr. The sarA/agr network is associated with the expression of cell wall-associated adhesins during exponential growth and the expression of secreted enzymes and toxins in the transition to post-exponential growth. A number of sarA homologs, including sarT and sarS, have been identified in the S. aureus genome. Previous studies have shown that sarA influences expression of both sarT and sarS in the …

Ccr5 Mediates Specific Migration Of Toxoplasma Gondii—Primed Cd8+ Lymphocytes To Inflammatory Intestinal Epithelial Cells, Souphalone Luangsay, Lloyd H. Kasper, Nicolas Rachinel, Laurie A. Minns

Dartmouth Scholarship

Toxoplasma gondii, an obligate intracellular parasite, can invade intestinal epithelial cells and elicit a robust Th1 immune response. In this model of intestinal inflammation, CD8⁺ intraepithelial lymphocytes (IELs) secrete transforming growth factor (TGF)-β, which appears necessary for the maintenance of homeostasis in the intestine. However, the mechanism responsible for the IEL migration to the inflamed intestine is still unclear.An in vitro coculture cell system was used to quantify the IEL attraction by an infected intestinal epithelial cell line (m-IC_cl2). We used CCR5-deficient mice to determine which chemokine receptor—chemokine interaction could be responsible for the recruitment of …

Dartmouth Scholarship

In vivo-induced antigen technology is a method to identify proteins expressed by pathogenic bacteria during human infection. Sera from 10 patients convalescing from cholera infection in Bangladesh were pooled, adsorbed against in vitro-grown El Tor Vibrio cholerae O1, and used to probe a genomic expression library in Escherichia coli constructed from El Tor V. cholerae O1 strain N16961. We identified 38 positive clones in the screen, encoding pili (PilA and TcpA), cell membrane proteins (PilQ, MshO, MshP, and CapK), methyl-accepting chemotaxis proteins, chemotaxis and motility proteins (CheA and CheR), a quorum-sensing protein (LuxP), and four hypothetical proteins. Analysis of immune …

Adolescent Violence Prevention: A Case Presentation, Hatim A. Omar, Joan Griffith

Pediatrics Faculty Publications

Violence in adolescence has seen an increase since the 1990s with dramatic statistics on violent death and risk behaviors. School violence has been focused upon by a huge media coverage of especially violent cases that could have had some endemic consequences worldwide. We present a case of a 14 year old white male with change in school behavior, strategies for the case investigation, its results, and long term prevention. Other research has shown that preventive measures during pregnancy, infancy and childhood can prevent adolescent and adult delinquency.

Homeland (In)Security : Roots And Displacement, From New York, To Toronto, To Salt Lake City, Marusya Bociurkiw

Reconstruction: Studies in Contemporary Culture

[First paragraph]

On September 11, 2001, broadcast and print media around the world narrated the destruction of New York City's World Trade Center and the deaths of thousands of its occupants. This paper will examine the ways in which television and its appendages (the telephone, the internet, the newspaper) operated to organize the discursive meanings of this traumatic event. I will propose that between September 11 and February 2002's Winter Olympics in Salt Lake City, Utah, ideas about home, roots and rootedness (and their Others: foreignness, homelessness, nomadicism) operated as a discursive mapping of that which could otherwise not be …

Alginate Is Not A Significant Component Of The Extracellular Polysaccharide Matrix Of Pa14 And Pao1 Pseudomonas Aeruginosa Biofilms, Daniel J. Wozniak, Timna J. O. Wyckoff, Melissa Starkey, Rebecca Keyser, Parastoo Azadi, George A. O'Toole, Matthew R. Parsek

Dartmouth Scholarship

The bacterium Pseudomonas aeruginosa causes chronic respiratory infections in cystic fibrosis (CF) patients. Such infections are extremely difficult to control because the bacteria exhibit a biofilm-mode of growth, rendering P. aeruginosa resistant to antibiotics and phagocytic cells. During the course of infection, P. aeruginosa usually undergoes a phenotypic switch to a mucoid colony, which is characterized by the overproduction of the exopolysaccharide alginate. Alginate overproduction has been implicated in protecting P. aeruginosa from the harsh environment present in the CF lung, as well as facilitating its persistence as a biofilm by providing an extracellular matrix that promotes adherence. Because of …

Ultrasonic Removal Of Bacteria From Plated Cells, Cecilia Chi-Pei Kao

Loma Linda University Electronic Theses, Dissertations & Projects

Children often present with dental trauma to pediatric emergency departments and pediatric dental offices. There is a wide spectrum of types of dental trauma. Although research has been done concerning the treatment of avulsed teeth, the current recommendations in the published guidelines might still be improved for better long term prognoses. One may speculate that ultrasonification of an avulsed tooth prior to replantation may dislodge existing surface bacteria and improve the prognosis for the tooth. This was as an in vitro study to test this concept. Epithelial cells were grown in 6-well tissue culture plates. Standardized amounts of Staphylococcus aureus …

Exploring The Physician’S Processes: Diagnosing Autism, Gwennyth Li Sze Palafox

Loma Linda University Electronic Theses, Dissertations & Projects

Physicians are customarily the first point of contact for parents who are concerned about a child’s development. Thus, it is important for physicians to be current and educated about childhood disorders and subsequent treatment for those disorders. Recently, empirical evidence has led to the proposal of early indicators of autism supporting that autism may be diagnosed accurately in children less than three years old. Furthermore, formal screening and assessment parameters developed by medical organizations have been proposed in order to identify autism as early as possible (American Academy of Neurology, 2000). While the proposed parameters and empirical evidence support early …

Regulation And Localization Of Endogenous Human Tristetraprolin, Anna-Marie Fairhurst, John E. Connolly, Katharine A Hintz, Nicolas J Goulding

Dartmouth Scholarship

Tumor necrosis factor (TNF) has been implicated in the development and pathogenicity of infectious diseases and autoimmune disorders, such as septic shock and arthritis. The zinc-finger protein tristetraprolin (TTP) has been identified as a major regulator of TNF biosynthesis. To define its intracellular location and examine its regulation of TNF, a quantitive intracellular staining assay specific for TTP was developed. We establish for the first time that in peripheral blood leukocytes, express

Photodynamic Therapy, Ashley Thomas

McCabe Thesis Collection

Photodynamic therapy is a new treatment that is being introduced into the veterinary community. Photodynamic therapy is the use of light activated chemotherapy to kill cancer cells (Dougherty, 1998). It has already been approved by the US Food and Drug Administration to be used as a form of cancer treatment in humans, but has not been carried over to the veterinary community. That is until now. Photodynamic therapy is now being tested in the veterinary community in hopes to find the same results that the human medical community has when dealing with certain types of cancer. They also hope to …
