We thank Takahashi and Matsubara for the interest in our article in which it was demonstrated that the placental thickness in the lower uterine segment is increased in women with abnormally invasive, compared to those with normal placentation. Takahashi & Matsubara argue that measurement of the placental thickness can be difficult in cases of central placenta previa. To support their argument, they show MRI images of central placenta previa. This article is protected by copyright. All rights reserved.

OBJECTIVE: To study the potential application of magnetic resonance imaging (MRI) for classification of retained placental tissue (RPT) in the uterus postnatally. METHODS: Twenty-two patients with clinically or pathologically proven RPT were studied. RESULTS: The thickness ratio (D1/D2) of invaded (D1) to normal (D2) myometrium could be categorized into 3 groups (>0.6, 0.1-0.6, and <0.1) correlating with the 3 types of RPT: accreta vera (RPA), increta (RPI), and percreta (RPP) (r = -0...

The placenta is a major driver of prenatal growth and involved in programming of postnatal performance. We therefore determined placental and embryo-fetal ultrasonographic parameters in early pregnancy and their relationships with birth weight and postnatal weights in a Bos indicus-Bos taurus composite beef cattle population. Pregnancies were generated in 2-yr-old Droughtmaster heifers by artificial insemination after estrus synchronization in 2 consecutive years (2009, n = 36 and 2010, n = 57), with a subset of 2010 heifers used again as lactating 3-yr-old cows in 2011 (n = 24)...

RESEARCH QUESTION: Does endometrial thickness affect the occurrence of obstetric complications in fresh IVF cycles? DESIGN: We conducted a retrospective cohort study that included all singleton deliveries resulting from fresh embryo transfers in a single centre between 2008 and 2014. Obstetric complications, i.e. preeclampsia, placental abruption, placenta previa, small for gestational age and preterm delivery, in singleton live births were compared among patients with an endometrial thickness of less than 7...

A growing body of evidence suggests that prenatal environment is important in Autism Spectrum Disorder (ASD) etiology. In this study, we compare placental shape features in younger siblings of children with ASD, who themselves are at high ASD risk, to a sample of low risk peers. Digital photographs of the fetal placenta surface and of the sliced placental disk from 129 high ASD risk newborns and from 267 newborns in the National Children's Study Vanguard pilot were analysed to extract comparable measures of placental chorionic surface shape, umbilical cord displacement and disk thickness...

Background/aim: This study evaluates diabetic macular-edema (DME) patients for the effect of intravitreal bevacizumab (IVB) injection on macular thickness and proangiogenic biomarkers in serum and vitreous. Materials and methods: Forty DME patients were analyzed for macular thickness (MT). Twelve proangiogenic biomarkers in serum and vitreous were analyzed before and after IVB. Results: Significant decrease in MT with vitreal vascular endothelial growth factor-A (VEGF-A) was observed as expected after IVB, while serum VEGF-A did not follow a decreasing trend in contrast to VEGF-C, which decreased both in serum and vitreous...

Introduction: Meshed split-thickness skin grafting represents a rapid and effective technique for surgical wound closure. Factors such as ongoing inflammation, microbial colonization, and a poorly vascularized wound bed increase the rate of skin autograft failure up to 33%. Because of the inherent angiogenic, anti-inflammatory, antimicrobial, and antifibrotic properties of human placental membranes, the complementary use of human placental membranes may promote graft survival and improve success rate for complete ulcer resolution...

The placenta plays a critical role in regulating fetal growth. Recent studies suggest that there may be sex-specific differences in placental development. The purpose of our study was to evaluate the associations between birthweight and placental morphology in models adjusted for covariates and to assess sex-specific differences in these associations. We analyzed data from the Stillbirth Collaborative Research Network's population-based case-control study conducted between 2006 and 2008, which recruited cases of stillbirth and population-based controls in 5 states...

BACKGROUND: Intrauterine adhesions (IUA) are the most common cause of uterine infertility and are caused by endometrium fibrotic regeneration following severe damage to the endometrium. Although current stem cell treatment options using different types of autologous stem cells have exhibited some beneficial outcomes in IUA patients, the reported drawbacks include variable therapeutic efficacies, invasiveness and treatment unavailability. Therefore, the development of new therapeutic stem cell treatments is critical to improving clinical outcomes...

INTRODUCTION: Ultrasound signs of abnormal placental invasion are subjective in nature. We tested the hypothesis that placental thickness in the lower uterine segment is increased when there is abnormally invasive placenta (AIP) in women with a low-lying placenta. MATERIAL AND METHODS: Retrospective analysis of data of placental thickness in women with ultrasound evidence of major placenta previa or a low-lying anterior placenta was done. The diagnosis of AIP was confirmed both intraoperatively and on histopathology for those managed by partial myometrial excision with uterine conservation or by hysterectomy...

This study aimed to investigate the effects of back-fat thickness (BF), at mating of sows, on placental lipotoxicity, oxidative stress, and inflammation. We performed iTRAQ labeling-based proteomic analysis on term placentas obtained by vaginal delivery from BFI (15-20 mm, control) and BFII (21-27 mm, obese) sows formed according to BF at mating. Proteomic analysis revealed 413 proteins to be significantly different in placenta from BFII sows by ≥1.2-fold. Gene ontology (GO) analysis identified proteins related to lipid metabolism and inflammatory response to be altered in placenta from obese sows...

A 15-year-old Warmblood mare, at 8 months of gestation, was presented to the Ghent University Faculty of Veterinary Medicine for evaluation of suspected stage one labor. Transrectal ultrasonography revealed no clear signs of placentitis or stage one labor. The combined thickness of uterus and placenta was 11 mm and the cervix was closed. Twin pregnancy was suspected by transabdominal ultrasonography but could not be confirmed with certainty. An electrocardiogram (ECG) was recorded from the mare's abdominal wall to register a fetal ECG...

The incorporation of the extracellular matrix (ECM) is essential for generating in vitro models that truly represent the microarchitecture found in human tissues. However, the cell-cell and cell-ECM interactions in vitro remains poorly understood in placental trophoblast biology. We investigated the effects of varying the surface properties (surface thickness and stiffness) of two ECMs, collagen I and Matrigel, on placental trophoblast cell morphology, viability, proliferation, and expression of markers involved in differentiation/syncytial fusion...

BACKGROUND: Presumably, progression of developmental retinal vascular disorders is mainly driven by persistent ischemia/hypoxia. An investigation into vision-threatening retinal ischemia remains important. Our aim was to evaluate, in relation to retinal ischemia, protective effects and mechanisms of Dendrobium nobile Lindley (DNL) and its bibenzyl component moscatilin. The therapeutic mechanisms included evaluations of levels of placental growth factor (PLGF) and Norrie disease protein (NDP)...

INTRODUCTION: Alkaline phosphatase is implicated in intestinal lipid transport and in the development of obesity. Placental alkaline phosphatase is localised to the microvillous plasma membrane of the placental syncytiotrophoblast at the maternal-fetal interface, but its role is unclear. We investigated the relations of placental alkaline phosphatase activity and mRNA expression with maternal body composition and offspring fat mass in humans. METHODS: Term human placentas from the UK Birthright cohort (n = 52) and the Southampton Women's Survey (SWS) (n = 95) were studied...
