The development of transgenic technology has enormous potential for livestock improvement. Several methods have been employed for generating transgenic livestock to date, the most popular being pronuclear injection or somatic cell nuclear transfer using genetically modified cells. However, the high cost and relatively low efficiencies seen with these methods have ...

Single blastocyst transfer has the advantage of maximizing the fresh single pregnancy rate. However, in patients with a low number of good quality embryos on day 3, it remains unclear whether immediate embryo transfer or further embryo culture with blastocyst transfer is the most preferable option. A retrospective cohort study ...

Pregnancy is accompanied by several hemodynamic, biochemical and hematological changes which revert to normal values after labor. The mean values of these parameters have been reported for developed countries, but not for Mexican women. Furthermore, labor constitutes a stress situation, in which these factors may be altered. It is known ...

Relaxin is an approximately 6-kilodalton peptide hormone secreted by the corpus luteum, and circulates in the maternal blood during pregnancy. Relaxin administration to awake, chronically instrumented, nonpregnant rats mimics the vasodilatory phenomena of pregnancy. Furthermore, immunoneutralization of relaxin or its elimination from the circulation during midterm pregnancy in awake rats ...

The FMR1 gene, mapping to an area of the X chromosome closely associated with autoimmunity also affects ovarian reserve, with specific genotypes associated with distinct ovarian aging patterns. They, therefore, could also be associated with differences of in vitro fertilization (IVF) outcomes, reported between races/ethnicities. We analyzed 339 consecutive IVF ...

Vascular endothelial growth factor receptor-2 (VEGFR2) plays a pivotal role in angiogenesis by eliciting vascular endothelial cell growth when bound to VEGF, a powerful pro-angiogenic ligand. While Vegf and Vegfr2 are expressed throughout gestation, the latter third of gestation in mice is characterized by a marked increase in fetoplacental angiogenesis. ...

Abstract Background. Pregnancy is a hypercoagulable state with a 5- to 10- fold higher risk of venous thromboembolism. Existing reference intervals for fibrin D-dimer (D-dimer), functional fibrinogen (fibrinogen) and protein S, free antigen (protein S) are based on non-pregnant patients and reference intervals for pregnant patients are warranted. Objectives. The ...

The placenta contains a large variety of metabolizing enzymes, among them UDP-glucuronosyltransferase (UGT). Several UGT2B isozymes have so far been detected in human placenta, but little is known on placental expression of UGT1A isozymes. The antiepileptic drug lamotrigine (LTG) is a UGT1A4-substrate, and its serum concentration falls by over 50% ...

SummaryIn mammals, fertilization and preimplantation embryo development occurs in the oviduct. Cross-talk between the developing embryos and the maternal reproductive tract has been described in such a way as to show that the embryos modulate the physiology and gene expression of the oviduct. Different studies have indicated that transforming growth ...

Angiogenesis is required for successful implantation of the invading blastocyst. Vascular endothelial growth factor (VEGF) is an important key player in angiogenesis and vascular remodeling during the implantation process. Besides its well-characterized receptors VEGFR1 and VEGFR2, neuropilin-1 (NRP-1) has been shown to play an additional role in the signaling process ...

Background: Persistent trophoblast is a recognised complication of salpingostomy for the treatment of ectopic pregnancy, with reported rates of 3-20%; hence, women are advised to have serum human chorionic gonadotrophin (hCG) levels monitored post-operatively. Although much less common, there are also reports of disseminated trophoblastic peritoneal implants after laparoscopic salpingectomy. ...

Preeclampsia is characterized by the onset of high blood pressure and proteinuria during pregnancy, which results in substantial maternal and neonatal morbidity and mortality. Insulin resistance has been observed before the onset of preeclampsia, and is implicated in its pathophysiology. Recently, retinol-binding protein 4 (RBP4), which carries retinol in circulation, ...

BACKGROUND: Human chorionic gonadotrophin (hCG) is a secretion of the placenta during pregnancy and gestational trophoblastic diseases. It increases as a consequence of abnormal placental invasion and placental immaturity. So, it is an important diagnostic marker of pregnancy and many diseases such as the hydatidiform mole, the choriocarcinoma, the orchic ...

The hypothesis of the present study was that a GnRH agonist application at early pregnancy would alter the pattern of the key reproductive hormones LH and FSH, and subsequently that of estradiol (E2) and especially progesterone (P4), and improve the conditions for embryo survival in early pregnant gilts. Therefore, the ...

Maternal thyroid hormone is provided to the fetus before the onset of fetal thyroid function (at about 16 weeks) and is essential for normal neurologic development. Mechanisms of transport are uncertain but transthyretin (TTR), a thyroxine binding protein produced by the placenta may be involved. Placental oxygen concentrations in early pregnancy ...

Pregnancy loss is a serious social and medical issue, with one important cause associated with aberrant embryo implantation during early pregnancy. However, whether and how the process of embryo implantation is affected by environmental factors such as stress-induced sympathetic activation remained elusive. Here we report an unexpected, transient effect of ...
