Rac-1 And Iqgap Are Potential Regulators Of E-Cadherin-Catenin Interactions During Murine Preimplantation Development., David R Natale, Andrew J Watson

Obstetrics & Gynaecology Publications

Adherens junction formation is fundamental for compaction and trophectoderm differentiation during mammalian preimplantation development. We recently isolated an IQGAP-2 cDNA from a differential display-polymerase chain reaction screen of bovine preimplantation developmental stages. IQGAP-1 and -2 proteins mediate E-cadherin-based cell-to-cell adhesion through interactions with beta-catenin and the Rho GTPases, rac1 and cdc42. Our study demonstrates IQGAP-1,-2, rac-1 and cdc42 mRNAs are present throughout murine preimplantation development. IQGAP-1 and rac-1 protein distribution changes from predominantly plasma membrane associated to predominantly cytoplasmic as the embryo progresses through cleavage divisions and compaction to the blastocyst stage.

The Gamma-Subunit Of The Na-K-Atpase As A Potential Regulator Of Apical And Basolateral Na+-Pump Isozymes During Development Of Bovine Pre-Attachment Embryos., L C Barcroft, S E Gill, A J Watson

Obstetrics & Gynaecology Publications

Expression and activity of the Na-K-ATPase within the basolateral membrane domains of the trophectoderm epithelium provide the driving force for accumulation of Na(+) and Cl(-) across the nascent epithelium, mediating fluid movement into the forming blastocoel. Within the trophectoderm of the bovine blastocyst, multiple isozymes of the Na-K-ATPase are expressed. Immunolocalization has demonstrated that the alpha1-isozyme localizes within the basolateral membrane, whereas the alpha 3-isozyme localizes to the apical cell margins. Gene-specific RT-PCR and wholemount indirect immunofluorescence confocal laser scanning microscopy were used to examine expression of the Na-K-ATPase gamma-subunit (a regulatory subunit of the Na-K-ATPase) throughout development of bovine …

Comparative Study--Efficacy, Safety And Compliance Of Intravenous Iron Sucrose And Intramuscular Iron Sorbitol In Iron Deficiency Anemia Of Pregnancy, A Wali, A Mushtaq, Nilofer

Department of Obstetrics & Gynaecology

Objective: (1) To determine an alternative iron supplementation with better efficacy, compliance & safety in treatment of iron deficiency anemia during pregnancy, (2) to reduce blood transfusion during pregnancy, labor and puerperium.
Material and Method: A prospective comparative study. A total number of 60 pregnant women with the gestational age of 12 - 34 weeks were included in the study who were suffering from iron deficiency anemia. They were divided in 3 groups (A, B and C). Group A (n15) received intravenous iron sucrose according to recommended dose containing 500 mg of iron sucrose for storage, in group B (n=20) …

Epidermal Growth Factor Receptor (Egfr) As A Prognostic Marker: An Immunohistochemical Study On 315 Consecutive Breast Carcinoma Patients, S. A. Aziz, Shahid Pervez, N. Kayani, M. H. Rahbar, S. Khan

Department of Pathology and Laboratory Medicine

Objective: To assess the independent and interdependent prognostic value of epidermal growth factor receptor (EGFR) in carcinoma of breast in female population. The Type I family of growth factor receptors includes epidermal growth factor receptor (EGFR also known as EGFRI).

Methods: The expression of EGFR protein was analysed immunohistochemically on 315 tumour specimens of infiltrating ductal carcinoma of breast. These patients also had axillary lymph nodes sampling.

Results: Overexpression and/or amplification of EGFR was observed in 70 (22.00%) tumours. Eleven (16%) were grade I, 43 (61%) grade II and 16 (23%) grade Ill tumours. Axillary lymph node metastasis had significant …

Prevalence And Risk Factors For Vaginal Candida Colonization In Women With Type 1 And Type 2 Diabetes, Ella M. De Leon, Scott J. Jacober, Jack D. Sobel, Betsy Foxman

Wayne State University Associated BioMed Central Scholarship

Abstract

Background

Diabetes mellitus increases the rate of vaginal colonization and infection with Candida species

Methods

We surveyed women with diabetes receiving care at either an urban or suburban diabetes clinic to examine the relationship between vaginal Candida colonization, diabetes type and duration, and HbA_1c level. 101 participants completed the self-administered questionnaire and self-collected a vaginal swab for Candida culture. Candida colonization was similar by age and race.

Results

Type 1 diabetics were three times as likely as type 2 diabetics to be colonized with any Candida species (OR = 3.4; 95% CI: 1.03, 11.41; p = 0.04); even …

Are You My Parent? Are You My Child? The Role Of Genetics And Race In Defining Relationships After Reproductive Technological Mistakes, 5 Depaul J. Health Care L. 15 (2002), Raizel Liebler

UIC Law Open Access Faculty Scholarship

Imagine that you are a married woman who wants to have a genetically related child with your husband. Your doctor tells you that you are infertile, and therefore you and your husband go to XYZ fertility clinic to receive in vitro treatment. You have your eggs harvested, your husband supplies sperm, and ten embryos are created. Five embryos are implanted in your uterus and five are frozen and kept by the fertility clinic for your later use. You successfully conceive and give birth to twins. You notice that the children you give birth to are of a different race than …

Jadelle® Levonorgestrel Rod Implants: A Summary Of Scientific Data And Lessons Learned From Programmatic Experience, Irving Sivin, Harold A. Nash, Sandra N. Waldman

Formulation/Product Development

This scientific monograph provides a comprehensive summary of the clinical characteristics of Jadelle levonorgestrel (LNG) rod implants, as observed during clinical trials conducted by the Population Council. The monograph also reviews lessons learned about how to provide Jadelle, based partly on conclusions gleaned from the extensive experience with Norplant, the earlier implant system, and suggests practical ways in which to introduce Jadelle into family planning programs.

Placental Peroxisome Proliferator-Activated Receptor Gamma And Leptin Receptor In Human Pregnancy, Gwyneth H. Gladstones

Theses : Honours

Leptin is a 16kDa peptide hormone that has recently been implicated in human reproductive processes. Like other hormones, leptin exerts its influence through its receptor. Of the three major isoforms of the receptor (OB-Ra, OB-Rb, and 0B-Re), OB-Ra (the dominant short form) has been implicated in transport processes within rat and human placentas, suggesting a role for it in implantation and pregnancy maintenance. The peroxisome proliferator-activated receptors (PPARs) are ligand-dependent transcription factors that are a subfamily of nuclear hormone receptors. PPARs form heterodimers with another nuclear hormone receptor, RXRα, before binding to PPAR response elements (PPREs). Recently PPARϒ/RXRα heterodimers have …

Using Operations Research To Strengthen Programmes For Encouraging Abandonment Of Female Genital Cutting. Report Of A Consultative Meeting On Methodological Issues For Fgc Research, Frontiers In Reproductive Health

Reproductive Health

The Population Council’s Frontiers in Reproductive Health program, with funding from USAID, organized a consultative meeting on the practice of female genital cutting (FGC) in Nairobi, Kenya in April 2002. The meeting brought together a small group of researchers and program managers who are actively undertaking operations research and systematic program evaluations to review the state of the art concerning intervention research design and measurement issues. The deliberations at this workshop should stimulate interest both in undertaking operations research more routinely when programming anti-FGC activities and in furthering the development and application of research methods appropriate for this subject. Several …
