Using vaginal misoprostol is an effective way of labor induction in term pregnant women with unfavorable cervices, since it is associated with a shorter duration of labor induction and higher rates of vaginal delivery within 12 h. Misoprostol and dinoprostone are equally safe, since misoprostol did not result in a rise in maternal and neonatal morbidity, namely, tachysystole, uterine hyperstimulation, cesarean section rates and admission to neonatal intensive care units as reported previously in literature.
Objective:To investigate the biochemical markers such as nitric oxide (NO), malondialdehyde (MDA) and reduced glutathione (GSH), indicators of the oxidative status of the follicle, to predict the outcome of in vitro fertilization. Material and Methods: Follicular aspirates of dominant follicleswere collected during oocyte retrieval. Biochemical analyses of NO, MDA and GSH were performed on all aspirates. Results:When the successful and unsuccessful pregnancy groups were compared in terms of NO, MDA and GSH, follicular fluid MDA was significantly higher (p=0.001) and follicular fluid NO level was significantly lower (p=0.039) in the pregnant group. Correlation analysis between oxidative stress and IVF parameters showed that MDA had a positive weak correlation with the number of grade 1 embryos (r=0.271, p=0.033) and fertilization rate (r=0.263, p=0.039). ROC curve analysis found that malondialdehyde has an area under the curve of 0.74 and can predict pregnancy with high sensitivity. Conclusion:As malondialdehyde was significantly different in pregnant and non-pregnant women and had a good sensitivity profile in predicting pregnancy, it may be considered a marker for predicting IVF success.

Gereç ve Original Investigation 136 IntroductionInfertility is defined as the inability to conceive for at least one year despite having regular sexual intercourse without using any contraception method. There are different causes of infertility. Nearly 40-50% of infertility problems are estimated to be of female origin and approximately 30% of cases are of male origin. A further 20-25% of couples suffer from unexplained factors (1). The pathophysiology of unexplained infertility is still a scientific question (2). In order to find some answers for unexplained cases, several investigators are trying to develop new, non-invasive biochemical markers that may affect gamete and embryo quality. Oxidative stress is being investigated as a causative marker in this manner. Studies on the pathophysiology of unexplained infertility have indicated that oxidative stress may be involved as an underlying factor (3, 4). The maintenance of homeostasis in cells requires a complex interaction between prooxidants and antioxidants. Oxidative stress occurs as a result of a shift in this balance between prooxidants and antioxidants towards excess free radical formation (5 Abstract Özet is malondialdehyde (MDA). Since it is a stable end product, it can be used as a cumulative measure of lipid peroxidation (6). Nitric oxide (NO) is an inorganic, short-lived free radical gas that is synthesized from L-arginine via NO synthases. It has various ...
BackgroundTurner’s syndrome (TS) is depicted as a total or partial absence of one X chromosome that results in ovarian dysgenesis. Chances of spontaneous pregnancy in TS are rare and the outcome of the pregnancies is known to be poor with an increased risk of miscarriage and stillbirths. Our aim is to evaluate reproductive and obstetric outcomes of natural conception and in-vitro fertilization (IVF) cycles in mosaic TS patients.MethodsA total of 22 mosaic TS cases (seventeen 45,X/46,XX and five 45,X/46,XX/47,XXX karyotypes) were evaluated.ResultsLive birth and abortion rates were found as 32.7 % and 67.3 %, respectively in 52 pregnancies. Implantation, clinical pregnancy and take home baby rates were detected as 3.7 %, 8.6 % and 5.7 %, respectively per IVF cycle as a result of 35 cycles. Fecundability analysis revealed that 5 % of the cases experienced first pregnancy within 6 months and 8 % within the first 2 years. Mosaicism ratio did not have an effect on the time to the first pregnancy (p = .149).ConclusionOnly a small proportion of the mosaic TS patients conceive in the first 2 years of the marriage. Age of menarche and age of marriage appear not to have any impact on the chance of conceiving. Mosaic TS cases should counseled about the low odds of pregnancy and high miscarriage rates.
Diabetes mellitus, a complex metabolic disorder, leads to many health complications like kidney failure, diabetic heart disease, stroke, and foot ulcers. Treatment approaches of diabetes and identification of the mechanisms underlying diabetic complications of the skin have gained importance due to continued rapid increase in the diabetes incidence. A thick and pre-vascularized in vitro 3D type 2 diabetic human skin model (DHSM) was developed in this study. The methacrylated gelatin (GelMA) hydrogel was produced by photocrosslinking and its pore size (54.85 ± 8.58 μm), compressive modulus (4.53 ± 0.67 kPa) and swelling ratio (17.5 ± 2.2%) were found to be suitable for skin tissue engineering. 8% GelMA hydrogel effectively supported the viability, spreading and proliferation of human dermal fibroblasts. By isolating dermal fibroblasts, human umbilical vein endothelial cells and keratinocytes from type 2 diabetic patients, an in vitro 3D type 2 DHSM, 12 mm in width and 1.86 mm thick, was constructed. The skin model consisted of a continuous basal epidermal layer and a dermal layer with blood capillary-like structures, ideal for evaluating the effects of anti-diabetic drugs and wound healing materials and factors. The functionality of the DHSM was showed by applying a therapeutic hydrogel into its central wound; especially fibroblast migration to the wound site was evident in 9 d. We have demonstrated that DHSM is a biologically relevant model with sensitivity and predictability in evaluating the diabetic wound healing potential of a therapeutic material.
