Vasculogenesis is a complex process by which endothelial stem and progenitor cells undergo de novo vessel formation. Quantitative assessment of vasculogenesis is a central readout of endothelial progenitor cell (EPC) functionality. However, current assays lack kinetic measurements. To address this issue, new approaches were developed to quantitatively assess in vitro endothelial colony forming cell (ECFC) network formation in real time. Eight parameters of network structure were quantified using novel Kinetic Analysis of Vasculogenesis (KAV) software...

OBJECTIVE: To compare breech outcomes when mothers delivering vaginally are upright, on their back, or planning cesareans. METHODS: A retrospective cohort study was undertaken of all women who presented for singleton breech delivery at a center in Frankfurt, Germany, between January 2004 and June 2011. RESULTS: Of 750 women with term breech delivery, 315 (42.0%) planned and received a cesarean. Of 269 successful vaginal deliveries of neonates, 229 in the upright position were compared with 40 in the dorsal position...

Several studies indicate that the fetal environment plays a significant role in the development of cardiometabolic disease later in life. However, a few studies present conflicting data about the correlation between birth weight and the impairment of cardiac autonomic modulation. The purpose of the present study was to provide further knowledge to elucidate this contradictory relationship. One hundred children aged 5 and 14 years had anthropometric parameters, body composition and blood pressure levels determined...

Left ventricular hypertrophy, diastolic dysfunction and fibrosis are main features of hypertrophic cardiomyopathy (HCM). Guidelines recommend β-adrenoceptor or Ca(2+) channel antagonists as pharmacological treatment. The Ca(2+) channel blocker diltiazem recently showed promising beneficial effects in pre-clinical HCM, particularly in patients carrying MYBPC3 mutations. In the present study we evaluated whether diltiazem could ameliorate or reverse the disease phenotype in cells and in vivo in Mybpc3-targeted knock-in (KI) mouse model of HCM...

Fetal growth restriction (FGR) affects around 5% of pregnancies and is associated with significant short- and long-term adverse outcomes. A number of factors can increase the risk of FGR, one of which is poor maternal diet. In terms of pathology, both clinically and in many experimental models of FGR, impaired uteroplacental vascular function is implicated, leading to a reduction in the delivery of oxygen and nutrients to the developing fetus. Whilst mechanisms underpinning impaired uteroplacental vascular function are not fully understood, interventions aimed at enhancing nitric oxide (NO) bioavailability remain a key area of interest in obstetric research...

BACKGROUND: ICU admission is uncommon among obstetric patients. Nevertheless, the epidemiology of ICU utilization is considered to be a useful proxy for study of severe maternal morbidity and near-miss events. However, there is paucity of population-level studies in obstetric patients in the United States. METHODS: The Texas Inpatient Public Use Data File and state-based reports were used to identify pregnancy-associated hospitalizations and those involving admission to ICU (n = 158,410) for the years 2001 - 2010...

Recommendations for opioid agonist pharmacotherapy and against medically assisted withdrawal were based upon early reports that associated withdrawal with maternal relapse and fetal demise. Data from recent case series have called these recommendations into question. Although these data do not support an association between medically assisted withdrawal and fetal demise, relapse remains a significant clinical concern with reported rates ranging from 17% to 96% (average 48%). Given the high loss to follow-up in these studies, the actual relapse rate is likely even greater...

Our previous studies demonstrated that treating pregnant rats with dioxins, including 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD), targets the pituitary expression of luteinizing hormone (LH) to attenuate testicular steroidogenesis in fetuses, resulting in the imprinting of sexual immaturity of the offspring after reaching maturity. Furthermore, we found that although TCDD disturbs the tricarboxylic acid (TCA) cycle in the fetal hypothalamus, maternal co-treatment with α-lipoic acid (α-LA), a cofactor of the TCA cycle, restores a TCDD-produced reduction in the LH-evoked steroidogenesis as well as the TCA cycle activity in fetuses...

In France, 60,000 neonates are born preterm every year (7.4%), half of them after the spontaneous onset of labor. Among preventable risk factors of spontaneous prematurity, only cessation of smoking is associated with decreased prematurity (level of evidence [LE]1). It is therefore recommended (Grade A). Routine screening and treatment of vaginal bacteriosis is not recommended in the general population (Grade A). The only population for which vaginal progesterone is recommended is that comprising asymptomatic women with singleton pregnancies, no history of preterm delivery, and a short cervix at 16-24 weeks of gestation (Grade B)...

BACKGROUND: Twin gestations are at significantly higher risk of fetal growth restriction in comparison with singletons. Using fetal biometric charts customized for obstetrical and parental characteristics may facilitate accurate assessment of fetal growth. OBJECTIVE(S): To construct reference charts for gestation of fetal biometric parameters stratified by chorionicity and customized for obstetrical and parental characteristics. STUDY DESIGN: Fetal biometric measurements obtained from serial ultrasound examinations in uncomplicated twin pregnancies delivering after 36 weeks of gestation were collected by 19 Italian fetal medicine units under the auspices of the Società Italiana di Ecografia Ostetrica e Ginecologica...

Batten disease (neuronal ceroid lipofuscinosis) refers to a group of neurodegenerative lysosomal storage diseases predominantly affecting children. There are currently no effective treatments, and the functions of many of the associated gene products are unknown. Here we characterise fetal neural cultures from two genetically distinct sheep forms of Batten disease, with mutations in the lysosomal protein encoding gene CLN5 and endoplasmic reticulum membrane protein encoding gene CLN6, respectively. We found similar reductions in autophagy, acidic organelles and synaptic recycling in both forms compared to unaffected cells...

Adults who were affected by intrauterine growth restriction (IUGR) suffer from reductions in muscle mass and insulin resistance, suggesting muscle growth may be restricted by molecular events that occur during fetal development. To explore the basis of restricted fetal muscle growth, we used a sheep model of progressive placental insufficiency-induced IUGR to assess myoblast proliferation within intact skeletal muscle in vivo and isolated myoblasts stimulated with insulin in vitro. Gastrocnemius and soleus muscle weights were reduced by 25% in IUGR fetuses compared to controls (CON)...

INTRODUCTION: Chronic reduction of oxygen and nutrient delivery to the fetus has been related to neurodevelopmental problems. Placental underperfusion induces a significant reduction in oxygen and nutrient delivery, whereas maternal undernutrition causes mainly nutrient deficiency. A comparison of the neurodevelopmental effects of both situations in pregnant rabbits was performed. MATERIALS AND METHODS: The placental underperfusion model was induced after uteroplacental vessel ligation at 25 days of pregnancy...

PURPOSE: Lead aprons are routinely used to shield the fetus from radiation during fluoroscopically guided interventions (FGI) involving pregnant patients. When placed in the primary beam, lead aprons often reduce image quality and increase fluoroscopic radiation output, which can adversely affect fetal dose. The purpose of this work is to identify an effective and practical method to reduce fetal dose without affecting image quality. METHODS: A pregnant patient equivalent abdominal phantom is set on the table along with an image quality test object (CIRS model 903) representing patient anatomy of interest...

The major goal of animal production is to obtain abundant and healthy meat for consumers. Maternal food restriction (MFR) is often applied in farms to reduce production costs. However, the suitability of MFR in livestock animals is questionable, as this management may compromise maternal fitness due to a severe negative energetic balance and can induce Intrauterine Growth Restriction (IUGR) and prenatal programming in the offspring. Here, we sought to determine, using pregnant rabbits, the consequences of MFR on maternal endocrine and metabolic status and conceptus development...

BACKGROUND: Advancements in medical technology have significantly increased the possibility of successful infertility treatment. Medical interventions in the initial process of pregnancy that intend to increase the chances of pregnancy create the risk of multifetal pregnancies for both mothers and fetuses. Physicians attempt to reduce the numbers of fetuses in order to decrease this risk and guarantee the continuation of pregnancy. The aim of this paper is to understand the Shiite instruction in terms of the risks multifetal pregnancies have for fetuses and if it is permissible to reduce the numbers of fetuses...

Heart consumes more energy than any other organ. It can utilize various metabolic substrates as a source of energy. The primary substrates are free fatty acids, especially long-chain fatty acids and glucose. The lipid bilayer of plasmalemma is impermeable for glucose. Therefore, glucose transport across the plasma membrane is mediated via glucose transporters. In human, cardiac cells are expressed as 2 families of glucose transporters: GLUTs and SGLTs. These transport proteins are GLUT1, GLUT3, GLUT8, GLUT10, GLUT11, GLUT12 and SGLT1...

OBJECTIVE: Describe tools designed to predict preterm birth in asymptomatic high-risk pregnancy and determine their predictive value. METHODS: The PubMed database, the Cochrane Library and the recommendations from the French and foreign obstetrical societies or colleges have been consulted. RESULTS: Obstetric history particularly spontaneous preterm birth identifies a population at risk for preterm birth for the current pregnancy (LE3). This risk is related to the number of prior preterm birth and is even higher than the term of the prior event is more premature and that the event concerns the last pregnancy (LE3)...
