Expression And Function Of Fgf-4 In Peri-Implantation Development In Mouse Embryos, Daniel A. Rappolee, Claudio Basilico, Yogesh Patel, Zena Werb

Department of Obstetrics and Gynecology Research Publications

One of the earliest events in mammalian embryogenesis is the formation of the inner cell mass (ICM) and the subse- quent delamination of primitive endoderm. We have found that mRNA for fibroblast growth factor (FGF)-4, but not FGF-3, is expressed in preimplantation mouse blastocysts and that the FGF-4 polypeptide is present in ICM cells. ICM-like embryonal carcinoma cells and embryonic stem cells also express FGF-4. Conversely, differentiated embryonal carcinoma cells in the endoderm lineage express FGF-3, but not FGF-4 mRNA. Although mouse embryos expressed FGF-4 mRNA from the 1-cell stage, embryos cultured from the 2-cell through the blastocyst stage in …

Bacteriuria And Pregnancy Outcome: A Prospective Hospital-Based Study In Pakistani Women, Rahat N. Qureshi, Khalid S. Khan, Omar Darr, Nasir Khattak, Bader J. Farooqui, Javed H. Rizvi

Department of Obstetrics & Gynaecology

The prevalence of bacteriuria in Pakistani women and its association with complications of pregnancy was studied. Out of 1579 women, 77 had bacteriuria (4.8%). There was no association of age, gravidity, parity, haemoglobin, pre-eclampsia, mode of delivery, gestational age at delivery, preterm delivery and low birth-weight with presence of bacteriuria. With detection and treatment the pregnancy outcome of women with bacteriuria in pregnancy was the same as that of those without.

Ai : Artificial Insemination Of Sheep, David Windsor

Journal of the Department of Agriculture, Western Australia, Series 4

Artificial insemination (Al) is used widely in the dairy and beef industries and often performed by farmers themselves. By contrast, sheep breeders generally require assistance from vets when frozen semen is to be used. However, recent experiments with frozen semen are indicating that do-it-yourself Al may soon become a reality.

Penetration Of Piperacillin/Tazobactam Into Gynecologic Tissues Following A Single Loading Dose Prior To Hysterectomy, William F. O'Brien, Shelley George

Obstetrics & Gynecology Faculty Publications

Objective: This study was undertaken to determine plasma and pelvic tissue concentrations of piperacillin/tazobactam following a single intravenous administration.Methods: Plasma and tissue samples were obtained following administration of 3 g of piperacillin and 0.375 g of tazobactam. Concentrations of these agents were determined by chromatography.Results: Plasma concentrations (mean ±SD) for piperacillin/tazobactam were 208 ± 87/27 ± 8 and 95 ± 53/14 ± 2, respectively, at 30 and 60 min after the start of the infusion. The 8:1 ratio between piperacillin and tazobactam in plasma remained constant for up to 96 min. Tissue concentrations yielded a broader range, but …

Complexity Of Fetal Movement Detection Using A Single Doppler Ultrasound Transducer, William A. Russell Jr., Curtis L. Lowery, Patrick J. Baggot, James D. Wilson, Robert Walls, Roger M. Hawk, Pam Murphy

Journal of the Arkansas Academy of Science

The objective of this paper is to discuss the complexity of fetal movement detection encountered during development and implementation of an automated single Doppler ultrasonic transducer based instrument. The single transducer instrument was intended to better quantify the duration, velocity, and magnitude of fetal movements. A Corometrics Model 116 fetal heart rate monitor was modified, and a fetal movement detection algorithm (Russell Algorithm) was developed to detect fetal movements on one and two (data fusion) transducers. A Hewlett-Packard (HP) M-1350-A fetal monitor and the Russell Algorithm were used to detect and record fetal movements concurrently on sixty patients between the …

Oral Contraceptives And Reproductive Cancers: Weighing The Risks And Benefits, Ann L. Coker, Susan Harlap, Judith A. Fortney

CRVAW Faculty Journal Articles

The hypothetical incidence of reproductive cancers resulting from oral contraceptive use was estimated in several models comparing the cumulative lifetime incidence of cancer of the breast, cervix, ovary and endometrium expected in pill users with the incidence expected in nonusers. The potential number of cancer-free days that would be gained or lost by pill users was com- pared with similar estimates among nonusers. If five years or more of pill use were associated with a 20% increase in the risk of breast cancerbeing diagnosed before age 50, a 20% increase in cervical cancer risk and a 50% reduction in the …

Comparison Of Primiparous Women's Expected And Experienced Pain In Labour, Shelagh Lawrence

Theses : Honours

Pain is a subjective phenomenon and is, in varying degrees, an inherent part of the childbirth experience. However, most Western societies view suffering as unacceptable and as such, regard analgesia as a necessity. Many women do not anticipate the intensity of pain experienced in childbirth and are, therefore, not ready to manage this amount of pain when it occurs. This prospective study compared the expected and experienced labour pain of 99 primiparous women, aged 17-40 years. The relationship between expected and experienced pain and acceptance of pregnancy; identification with the motherhood role; relationship with mother; relationship with husband/partner; preparation for …

How To Make A Blastocyst., A J Watson, G M Kidder, G A Schultz

Obstetrics & Gynaecology Publications

Several of the new reproductive technologies have been cultivated from our current understanding of the genetic programming and cellular processes that are involved in the major morphogenetic events of mammalian preimplantation development. Research directed at characterizing the patterns of gene expression during early development has shown that the embryo is initially under maternal control and later superseded by new transcriptional activity provided by the activation of the embryonic genome. Several embryonic transcripts encoding: (i) growth factors, (ii) cell junctions, (iii) plasma membrane ion transporters, and (iv) cell adhesion molecules have been identified as contributing directly to the progression of the …

Sex Selection: Regulating Technology Enabling The Predetermination Of A Child's Gender, Owen D. Jones

Vanderbilt Law School Faculty Publications

The debate over the prohibition of sex (or gender) selection (also known as "preselection" or "predetermination"), has focused almost exclusively on the context of aborting a "wrong-sex" fetus after a fetal gender-identification procedure. Despite the fact that sex selection abortions represent only a small subset of sex selection procedures, attitudes toward the former are driving general policy approaches to the latter. However, the issues are analytically distinct, and only during the former infancy of the pre-conceptive (and non-abortive post-conceptive) technology for sex selection were members on both sides of the debate afforded the economy of using one logic to support …

Cortisol In The Ovine Fetus : Its Regulation And Role In Parturition, Ede Marie Apostolakis

Loma Linda University Electronic Theses, Dissertations & Projects

In fetal sheep, circulating cortisol increase during late gestation to abruptly rise 72 hours preceding birth. Although the surge in cortisol is thought to initiate the endocrine cascade which triggers parturition, it is not known what drives the prepartum rise in fetal cortisol. The first study tested the hypothesis that basal cortisol secretion is regulated by adrenocorticotropin (ACTH) which in turn, is controlled by arginine vasopressin (AVP). The fetus challenged with AVP increased plasma ACTH and cortisol concentrations. Pretreatment with an AVP V₁ receptor antagonist blocked AVP-induced plasma ACTH cortisol but failed to alter basal ACTH or cortisol. To …

Finding Hiv-Infected Women - The Clinician's Role, Mary Guinan

School of Public Health Faculty Research

An estimated 100,000 women are currently infected with the human immunodeficiency virus (HIV) in the United States, and a great majority of them are unaware of their condition. Approximately 20,000 HIV-infected women were identified through publicly funded HIV screening programs in 1989 and 1990, and an unknown number through private screening. Because most HIV-infected women are believed to be in the lower socioeconomic strata, it is unlikely that a significant number were identified in the private sector. Therefore, up to 80% of HIV-positive women may not know they are infected.

Insulin-Like Growth Factor Ii Acts Through An Endogenous Growth Pathway Regulated By Imprinting In Early Mouse Embryos, Daniel A. Rappolee, Karin S. Sturm, Ole Behrendtsen, Gilbert A. Schultz, Roger A. Pedersen, Zena Werb

Department of Obstetrics and Gynecology Research Publications

We present evidence that insulin-like growth factor II (IGF-II) mediates growth in early mouse embryos and forms a pathway in which imprinted genes influence development during preimplantation stages, mRNA and protein for IGF-II were expressed in preimplantation mouse embryos, but the related factors IGF-I and insulin were not. IGF-I and insulin receptors and the IGF-II/mannose-6-phosphate receptor were expressed. Exogenous IGF-II or IGF-I increased the cell number in cultured blastocysts, but a mutant form of IGF-II that strongly binds only the IGF-II receptor did not. Reduction of IGF-II expression by antisense IGF-II oligonucleotides decreased the rate of progression to the blastocyst …

Platelets And Leucocyte Counts In Pregnancy, Saadiya Aziz Karim, Javaid H. Rizvi, Iffat Rizwana, Mohammad Khurshid, Sadiqua N. Jafarey

Department of Obstetrics & Gynaecology

A study involving the obstetric clinic population of 3 major teaching hospitals of Karachi has been conducted to define changes in leucocyte and platelet counts as pregnancy progresses. 573 “normal” pregnant women - 183 in the first trimester, 195 in the second trimester and 194 in the third trimester were included in this analysis. We have found leucocytosis to be a feature of normal pregnancy; the change is subsequent to a progressive increase in granulocytes. Platelet counts were found to decrease slightly as pregnancy progresses

The purpose of this study was to determine women's: current knowledge of the menopause and of the disease osteoporosis; attitudes to estrogen replacement therapy (ERT); frequency of menopausal symptoms; knowledge-seeking behaviours In relation to the menopause; and, open-ended responses to menopausal issues. This study surveyed 70 women who responded to an advertisement in Community Newspapers. Data were collected using a "Knowledge and attitudes to the menopause and health related issues" (KAMHRI) questionnaire. The KAMHRI questionnaire was developed by the researcher and …

Female Condoms, An Urgent Need, Mary Guinan

School of Public Health Faculty Research

As of February 1991, more than 16,000 cases of AIDS in women had been reported in the United States, but the ". tidal wave of cases in women is yet to come. World Health Organization (WHO) estimates of the number of women infected with the human immunodeficiency virus (HIV) range from 1.5 million in Africa to I 00,000 in the United States. Within the next ten years, the majority of these women will develop AIDS and die. Some will live a bit longer, but all are eventually doomed to die prematurely. Most will not live to see their 40th year.

A Clinicopathological Analysis Of Ovarian Tumours, M Saeed, K Khawaja, I Rizwana, Iffat Rizwana, J Rizvi, Imtiaz Malik, A Khan

Department of Obstetrics & Gynaecology

We performed a retrospective analysis of patients with ovarian tumors who were admitted to the Aga Khan University Hospital from January 1985 to December 1989. Sixty one cases were reviewed. Mean age of the whole group was 44 years. Majority of the patients presented with abdominal pain and distention. Most frequent physical finding was a palpable mass on pelvic or abdominal examination. Overall these patients had a higher incidence of breast cancer than expected in the general population. Two-thirds of the tumors were malignant. Comparison of the patients with malignancy against those with benign tumors failed to show any correlation …

Development And Characterization Of Monoclonal Antisperm Antibodies: Potential For Contraception, Dilrowshan H. Haque

Theses and Dissertations in Biomedical Sciences

There is an expressed need to develop a greater variety of safe contraceptive methods which would find acceptance worldwide, particularly in developing countries. Immunization against spermatozoa might be such a method as judged by the accumulated evidence from studies on human females and in a number of female animal species.

Two extraction techniques were used for sperm membrane antigen isolation. The first technique involved NP-40 detergent for antigen extraction from human motile sperm and the second technique employed homogenized human testis for antigen extraction. Using these immunogens, sperm membrane-specific monoclonal antibodies (MAbs) were developed. When these antisperm MAbs were subjected …

Gestational Diabetes In A Developing Country, Experience Of Screening At The Aga Khan University Medical Centre, Karachi, Khalid S. Khan, Javaid H. Rizvi, Rahat Qureshi, Rauf Mazhar

Department of Obstetrics & Gynaecology

In order to determine the prevalence of glucose intolerance in pregnancy, 1267 consecutive women attending the antenatal clinic of the Aga khan University Medical Centre were subjected to a 75g glucose challenge followed 2hr later by plasma glucose determination irrespective of gestation on the first antenatal visit. The test was repeated at 28-32 weeks of gestation if the patients had an abnormal initial screen at < 28 weeks gestation and a normal glucose tolerance test on diagnostic follow-up and for those who had a risk factor for gestational diabetes and a normal initial screen at < 28 weeks gestation. The glucose challenge test was abnormal (2hr plasma glucose> 1 40mg%) in 8.6% of the screened population. Follow-up oral glucose tolerance test on these patients revealed a prevalence of 3.2% of gestationat diabetes and 1.9% of impaired glucose tolerance test based on the modified …

Prophylatic Cord Care: Is It Necessary?, Karen Coyle

Theses : Honours

Since the evolution of 'open' cord care in 1974, the umbilical cord of the newborn has been treated prophylactically with many different forms of antibacterial solutions. Recent studies have demonstrated that cord separation is facilitated by bacteria and many of the current treatments, such as the use of alcohol, actually delay separation. The purpose of this study was to compare cleaning the cord with alcohol to dry cord care, a method of cord care which is now being considered as an acceptable alternative to prophylactic umbilical cord treatment. A convenience sample of 205 babies was taken from a small private …

Platelet A-Granule Fibrinogen, Albumin, And Immunoglobulin G Are Not Synthesized By Rat And Mouse Megakaryocytes, Prem Handagama, Daniel A. Rappolee, Zena Werb, Jack Levin, Dorothy F. Bainton

Department of Obstetrics and Gynecology Research Publications

It has been assumed that endogenous synthesis by the platelet precursor cell, the bone marrow megakaryocyte, is the major source of platelet a-granule protein. To test this hypothesis, we used mRNA phenotyping to detect in megakaryocytes the presence of mRNA transcripts specific for various proteins. Our results indicate that megakaryocytes synthesize platelet factor 4, a protein relatively specific for platelets, but do not express mRNA transcripts for the fibrinogen, albumin, or IgG found in a-granules. We have previously shown that mega- karyocytes endocytose circulating proteins, including fibrino- gen, albumin, and IgG, and incorporate them into a-granules. Thus, platelets appear to …

Two Alkaline Phosphatase Genes Are Expressed During Early Development In The Mouse Embryo, Ann C. Hahnel, Daniel A. Rappolee, Jose Luis Millan, Thomas Manes, Carol A. Ziomek, Nicoleta G. Theodosiou, Zena Werb, Roger A. Pedersen, Gilbert A. Schultz

Department of Obstetrics and Gynecology Research Publications

Alkaline phosphatase (AP) activity is stage specific in mouse embryos and may be associated with compaction and separation of trophectoderm from inner cell mass in preimplantation development. We previously sequenced a cDNA and two mouse AP genes that could contribute to the AP activity in embryos. Oligonucleotide primers were constructed from the three sequences and used in the reverse transcription-polymerase chain reaction technique to establish that two of the three AP isozymes are transcribed during preimplantation development. The predominant transcript (E-AP) is from a gene highly homologous to the human tissue-specific APs, but different from the mouse intestinal AP. Tissue …

Amwa Endorses Uniform Mammography Screening, Mary Guinan

School of Public Health Faculty Research

Breast cancer is gaining on us at an increasing rate each year. In 1990 in the United States alone we expect about 145,000 new cases and 45,000 breast cancer deaths in women. What are we doing about it? What is AMWA doing, and what are women physicians doing- for themselves and their patients? Can we do anything? The answer is yes, we can. We can reduce mortality considerably if the cancer is detected early. The five-year survival rate for women with breast cancer diagnosed in its early (localized) stages is 90%, but for women with cancer diagnosed after it has …

Serum Cholesterol In Neonates And Their Mothers. A Pilot Study, S.H. Badruddin, R. Lalani, Mohammad Khurshid, A. Molla, R. Qureshi, M.A. Khan

Department of Medicine

Reports from the Aga Khan University indicate that 58% of 400 school children studied had undesirably high serum cholesterol levels. The present study was undertaken to determine whether the high cholesterol levels are present at birth and to determine the relationship between cord blood, maternal blood cholesterol and maternal diet. Cord blood from 58 neonates and fasting venous blood form 45 mothers were analyzed for total serum cholesterol. Mothers were interviewed regarding their usual diet during pregnancy. Mean cord blood cholesterol was 56.90 mg/dl (range 26 to 123 mg/dI). Mean maternal blood cholesterol was 232.4mg/dl (range 141-382 mg/dl). Mean maternal …

Genes For Extracellular Matrix-Degrading Metalloproteinases And Their Inhibitor, Timp, Are Expressed During Early Mammalian Development, C. A. Brenner, R. R. Adler, D. A. Rappolee, R. A. Pedersen, Z Werb

Department of Obstetrics and Gynecology Research Publications

Extracellular matrix (ECM) remodeling accompanies cell migration, cell-cell interactions, embryo expansion, uterine implantation, and tissue invasion during mammalian embryogenesis. We have found that mouse embryos secrete functional ECM-degrading metalloproteinases, including collagenase and stromelysin, that are inhibitable by the tissue inhibitor of metalloproteinases (TIMP) and that are regulated during peri-implantation development and endoderm differentiation. mRNA transcripts for collagenase, stromelysin, and TIMP were detected as maternal transcripts in the unfertilized egg, were present at the zygote and cleavage stages, and increased at the blastocyst stage and with endoderm differentiation. These data suggest that metalloproteinases function in cell-ECM interactions during growth, development, and …

Three Cheers For Elective Hysterectomy, Mary Guinan

School of Public Health Faculty Research

Hysterectomy is the second (after cesarean section) most commonly performed major surgical procedure in the United States today.1 About [650,000 American women will have hysterectomies in 1989. Thirty-seven percent of all US women will have had a hysterectomy by the time they reach age 60. The number of hysterectomies increased dramatically Born 1965 to 1975, but then leveled off and decreased to the present level of about 7 per 1000 women. The ~ghest rates occur in women aged 35 to 44 years, the age group the so called baby boomers are now entering in large numbers. Therefore, if the age-specific …
