OBJECTIVES: A proper implantation of trophoblastic cells and an appropriate metalloproteinases activity is required to cause disintegration of basal membranes of cells. The activity of tissue matrix metaloproteinases can be inhibited by their matrix inhibitors - TIMP-s. Survivin is a member of inhibitor of apoptosis proteins family (IAP), that suppresses caspase activation, influences VEGF expression and promotes proliferative action of endothelial cells. MATERIAL AND METHODS: The aim of the study was to assess concentrations of two independent anti-apoptotic factors...

OBJECTIVES: In mothers with pre-gestational or gestational diabetes, abnormal arterial stiffness (stiffer arteries) has been reported. The impact of abnormal maternal arterial stiffness on fetal placental and cardiovascular physiology is unknown. The purpose of the study was to determine the impact of maternal diabetes on maternal arterial stiffness and the association with fetal cardiovascular physiology as measured by fetal echocardiography. METHODS: Between December 2013 and January 2017 we conducted a prospective study on diabetic (otherwise healthy) and non-diabetic, healthy pregnant mothers (at 20-28 gestational weeks and 18-40 years of age) who had a normal fetal cardiac echocardiogram and obstetric ultrasound...

BACKGROUND: The results presented by studies investigating the effect of remifentanil on both parturients and newborns during cesarean section differed significantly. Therefore, we performed a meta-analysis to estimate the effect of remifentanil on these patients. METHODS: Potentially eligible studies published before 15 March 2016 were searched through four databases including PubMed, SCOPUS, ISI web of knowledge and EBSCO. Weighted mean difference (WMD) or odds ratios (ORs) and the corresponding 95% confidence interval (CI) were applied to estimate the strength of relationship...

Dysfunctional uterine bleeding is a common presentation of women in the emergency department. We describe the case of a 33-year-old female who presented with intermittent spotting due to an acquired uterine AVF. The patient underwent a transvaginal pelvic ultrasound as well as a CT angiogram. The patient was treated conservatively and elected to undergo uterine artery embolization in an effort to preserve fertility. She successfully delivered a healthy baby boy at 39-week gestation via an emergent caesarian section due to a prolapsed umbilical cord 17 months after undergoing the uterine artery embolization...

Umbilical cord entanglement is the leading cause of fetal mortality in monoamniotic twin pregnancies and a pseudo monoamniotic environment. Published methods for detecting this complication include color Doppler and pulsed Doppler sonography; however, no method provides an absolute diagnosis. In this case, we report the diagnosis of umbilical cord entanglement using dual-gate Doppler imaging. A 35-year-old woman was referred to our hospital at 28 weeks of gestation for prenatal management because of diagnosis of a monochorionic diamniotic twin pregnancy with spontaneous septostomy of the dividing membranes...

The therapeutic effect of transplantation of human umbilical cord blood cell-derived mononuclear cells (HUCMNCs) on treating in-stent restenosis (ISR) after endovascular interventional therapy (EIT) was evaluated in preclinical rabbit model of type 2 diabetes mellitus (T2DM)-related peripheral artery disease (PAD). HUCMNCs were transplanted to T2DM rabbits subjected to femoral artery occlusion surgery and received EIT. Serum concentration of soluble vascular endothelial cadherin (VE-cad) and plasma concentration of lipoprotein-associated phospholipase A2 (Lp-PLA2) were determined with enzyme-linked immunosorbent assay before and after the transplantation...

Chronic moderate hypoxia, such as occurs in fetal growth restriction (FGR) during gestation, compromises the blood-brain barrier (BBB) and results in structural abnormalities of the cerebral vasculature. We have previously determined the neuroprotective and antioxidant effects of maternal administration of melatonin (MLT) on growth-restricted newborn lambs. The potential of maternal MLT therapy for the treatment of cerebrovascular dysfunction-associated developmental hypoxia has also been demonstrated in newborn lambs...

This prospective cohort study aimed to evaluate the role of premature placental calcification in adverse pregnancy outcomes and identify its associated potential risk factors. We consecutively enrolled 293 women who presented to three academic medical centres from September 2011 to March 2013. Participants underwent transabdominal sonographies between 28-36 weeks of gestation in an attempt to determine placental maturity. We compared maternal and foetal outcomes between two groups of women, those with grade III placenta (n = 69) and those without grade III placenta (n = 224)...

BACKGROUND: Chronic hypertension in adults causes arterial lengthening in major arteries, but the effects of early fetal hypertension on the twin-twin transfusion syndrome (TTTS) recipient's vascular architecture remains unknown. OBJECTIVES: We hypothesize that arterial cord redundancy is related to recipient hypertension and subsequent heart failure. Our objectives were: 1) to establish a 3D color Doppler ultrasound method of measuring umbilical arterial (UA) length relative to its corresponding venous segment in the Umbilical cord using AV-angle, 2) to compare recipient AV-angle to gestational age-matched controls, and 3) to test the association of AV-angle with recipient heart failure...

Preeclampsia (PE) is associated with increased fetal hemoglobin (HbF) in the maternal circulation but its source is unknown. To investigate whether excessive HbF is produced in the placenta or the fetus, the concentration of HbF (cHbF) in the arterial and venous umbilical cord blood (UCB) was compared in 15825 normotensive and 444 PE pregnancies. The effect of fetal gender on cHbF was also evaluated in both groups. Arterial and venous UCB sampled immediately after birth at 36-42 weeks of gestation were analyzed for total Hb concentration (ctHb) (g/L) and HbF% using a Radiometer blood gas analyzer...

Around 2% of the population in developed nations are affected by mitral valve disease and available valvular replacements are not designed for the atrioventricular position. Recently our group developed the first tissue-engineered heart valve (TEHV) specifically designed for the mitral position - the TexMi valve. The valve recapitulates the main components of the native valve, i.e. annulus, asymmetric leaflets and the crucial chordae tendineae. In the present study, we evaluated the human umbilical cord as a clinically applicable cell source for the TexMi valve...

Hematopoietic Stem and Progenitor Cells (HSPCs) sustain life-long hematopoiesis and are first detected in the embryo by transplantation at embryonic day 10.5. (E10.5). HSPCs are mesodermal in origin and ultimately emerge from a subset of arterial endothelium (i.e. hemogenic endothelium), which is highly concentrated in the aorta-gonad-mesonephros region (AGM) of the mid-gestation embryo. Here, we employ clonal ex vivo assays in which endothelial cells isolated from the mid-gestation aorta and vitelline and umbilical arteries are co-cultured on supportive stroma to show that only about 0...
