Patients As Subjects For Research: Ethical Dilemmas For The Primary Care Clinician-Investigator, Susan F. Slatkoff, Peter Curtis, Ann L. Coker

CRVAW Faculty Journal Articles

Background: Past studies suggested an association between human papillomavirus (HPV) and cervical intraepithelial neoplasia (CIN). In 1987, University of North Carolina (UNC) Hospitals Family Practice Center clinicians were approached for a control population to study this association. Methods: One hundred fives patients attending the UNC Hospitals Neoplasia Clinic with biopsy-proven CIN 2 or 3 and 268 control patients attending the UNC Family Practice Center for a routine Papanicolaou smear were enrolled in this case-control study. Case and control patients consented to having an additional cervical specimen taken and to being interviewed. The cervical specimens were classified by the Southern blot …

A Growth Factor Phenotype Map For Ovine Preimplantation Development., A J Watson, P H Watson, M Arcellana-Panlilio, D Warnes, S K Walker, G A Schultz, D T Armstrong, R F Seamark

Obstetrics & Gynaecology Publications

The reverse transcription-polymerase chain reaction (RT-PCR) was used to determine the patterns of expression for several growth factor ligand and receptor genes during ovine preimplantation development. Transcripts for insulin-like growth factor (IGF)-I, IGF-II, and the receptors for insulin and IGF-I were detected throughout ovine preimplantation development from the 1-cell to the blastocyst stage. Transforming growth factor alpha (TGF alpha) transcripts were also detected throughout ovine preimplantation development. The mRNAs encoding basic fibroblast growth factor (bFGF) were detected in all stages of the ovine preimplantation embryo, although the relative abundance of this transcript consistently decreased from the 1-cell to the blastocyst …

Preimplantation Development Of In Vitro-Matured And In Vitro-Fertilized Ovine Zygotes: Comparison Between Coculture On Oviduct Epithelial Cell Monolayers And Culture Under Low Oxygen Atmosphere., A J Watson, P H Watson, D Warnes, S K Walker, D T Armstrong, R F Seamark

Obstetrics & Gynaecology Publications

The roles of medium composition, serum source, embryo coculture, and culture under low O2 conditions on the development of in vitro-matured and in vitro-fertilized (IVMF) ovine zygotes were investigated in three separate experiments. In the first experiment, the proportion of cocultured IVMF zygotes developing to the blastocyst stage was significantly higher (38.0% vs. 3.5%; p < 0.05) than that of non-cocultured zygotes treated within three embryo culture media (TCM-199 + 10% fetal bovine serum [FBS]; bicarbonate-buffered, glucose-free synthetic oviduct fluid medium [mod-SOFM] + 10% FBS; and bicarbonate-buffered BSA-free Tyrode's salt solution [mod-TALP] + 10% FBS) under a 5% CO2 atmosphere in air. In a second experiment, a significantly higher (p < 0.05) proportion of cocultured zygotes placed in TCM-199 medium survived to the blastocyst stage (37.4% blastocysts vs. 23.4% in mod-SOFM). No significant effect of serum (FBS vs. human serum [HS]) was observed on embryonic development, but coculture was confirmed to exert a significant influence on development to the blastocyst stage. In the final experiment, survival of the embryo under a reduced oxygen (5% CO2:5% O2:90% N2) atmosphere was investigated. In contrast to results in the initial experiments, embryonic survival was significantly higher (p < 0.05) in the non-cocultured treatment groups (21.9% blastocysts vs. 0.4% for cocultured zygotes). Serum source also had a significant (p < 0.05) influence upon the development of non-cocultured zygotes: 32.3% of zygotes cultured with HS progressed to the blastocyst stage vs. 11.5% of zygotes cultured in FBS-supplemented medium. These results have characterized two distinct culture environments, each capable of supporting the development of high frequencies of unselected IVMF zygotes to the blastocyst stage in vitro.

Immunologic Evaluation Of Ectopic Gestation, Tawfig Amin Nasser

Health Services Research Dissertations

Ectopic gestation is an error in the implantation site of the blastocyst. Extrauterine implantation presents a unique environment since the protective features of the uterus are absent. This study is an investigation into the immunoregulatory differences that may develop as a result of a change in the feto-maternal junction.

The effects of female plasma on one-way mixed lymphocyte cultures and mitogen-stimulated cultures, anti-paternal lymphocytotoxicity, and lymphocyte phenotypes were determined on normal, ectopic and non-pregnant females. The results indicated that pregnant female plasma enhanced the response of autologous lymphocytes to spouse and male control lymphocytes. Enhancement was not seen in the …

Possible Roles Of Insulin And Insulin-Like Growth Factors In Rat Preimplantation Development: Investigation Of Gene Expression By Reverse Transcription-Polymerase Chain Reaction., X Zhang, G M Kidder, A J Watson, G A Schultz, D T Armstrong

Obstetrics & Gynaecology Publications

The sensitive mRNA phenotyping technique of reverse transcription-polymerase chain reaction was used to demonstrate that insulin receptor mRNA is present in rat embryos during the preimplantation period. In addition, mRNA encoding insulin-like growth factor (IGF) type I and type II receptors have also been detected in rat preimplantation embryos. IGF-I mRNA was not detected in preimplantation embryos but was found in oviducts and uteri of prepubertal and early pregnant rats. IGF-II mRNA was present in both embryos and in oviducts and uteri during the preimplantation period. These findings suggest that insulin and IGF-I could influence early embryo development in endocrine …

Laparoscopic Appraisal Of Infertility And Pelvic Pain In Pakistani Women: A 5 Years Audit, R Hamid, K S. Khan, T Mubeen, J A. Razzak

Department of Obstetrics & Gynaecology

Five hundred and nine Laparoscopic examinations performed between 1987-91, (147 procedures for evaluation of gynaecologic pelvic pain and 313 for infertility) revealed ectopic pregnancy (27%), twisted ovarian cyst (18%) and acute pelvic inflammatory disease (14%) in cases of acute gynaecologic pain, and endometriosis (17%) and chronic pelvic inflammatory disease (16%) in chronic pelvic pain. Adhesions (20%), tubal block (15%), endometriosis (9%) and polycystic ovary (7%) were common findings in cases of infertility. These data support the usefulness of this minimally invasive procedure in accurate diagnosis of gynaecological disorders and provides insight into the spectra of diseases seen in Pakistani women …

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 …

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.

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 …

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