Begonia kingdon-wardii Tebbitt was rediscovered in 2014 from Myanmar after 67 years based on its last collection in 1937. Its previously unknown female flower and inaccurate morphology of leaf and ovary have been additionally described. This species belongs to Begonia sect. Sphenanthera (Hassk.) Warb. due to its dioecious habit, 3-locular ovary, berry fruits and thick placenta segments. Morphologically, it is similar to Begonia gulinqingensis S. H. Huang & Y. M. Shui in the leaf shape, placentation and fruit shape, but different in its dioecious plants, pliciform leaves, two-petalled female flowers and berry fruits...

This study investigated the influence of sow backfat thickness at 109 d of gestation on sow and piglet performance. Data from 846 farrowing multiparous Yorkshire sows with parity from 3 to 5 were collected from a pig breeding farm. Sows were divided into six groups based on backfat thickness (≤ 16, 17-18, 19-20, 21-22, 23-24, and ≥ 25 mm) at 109 d of gestation. The evaluation of reproductive performance included the litter size, litter weight at birth and at weaning of 21 d, weight of placenta at parturition, placental efficiency, and sow daily feed intake of lactation...

Hypertensive disease of pregnancy (HDP) with placental insufficiency is the most common cause of fetal growth restriction (FGR) in the developed world. Despite the known negative consequences of HDP both to the mother and fetus, little is known about the longitudinal placental changes that occur as HDP progresses in pregnancy. This is because longitudinal sampling of human placentae during each gestation is impossible. Therefore, using a mouse model of thromboxane A2-analog infusion to mimic human HDP in the last trimester, we calculated placental efficiencies based on fetal and placental weights, quantified spongiotrophoblast and labyrinth thicknesses and vascular density within these layers, examined whether hypoxia signaling pathway involving vascular endothelial growth factor A (VEGFA) and its receptors (VEGFR1, VEGFR2) and matrix metalloproteinases (MMPs) contributed to vascular change, and examined nutrient transporter abundance including glucose transporters 1 and 3 (GLUT1, GLUT3), neutral amino acid transporters 1, 2, and 4 (SNAT1, SNAT2, and SNAT4), fatty acid transporters 2 and 4 (FATP2, FATP4) and fatty acid translocase (CD36) from embryonic day 15...

Maternal depressive symptoms during pregnancy predict increased psychiatric problems in children. The underlying biological mechanisms remain unclear. Hence, we examined whether alterations in the morphology of 88 term placentas were associated with maternal depressive symptoms during pregnancy and psychiatric problems in 1.9-3.1-years old (Mean = 2.1 years) toddlers. Maternal depressive symptoms were rated biweekly during pregnancy with the Center of Epidemiological Studies Depression Scale (n = 86)...

RATIONALE: Occupational burn injuries can be detrimental and difficult to manage. The majority of complex cases are referred and managed at regional burn centers where access to specialized care is available. As an alternative to hospitalization with staged surgical procedures, placental products may be used for outpatient medical management of these common burn injuries, especially if access to a regional burn center is limited or restricted.Fresh amnion has been a treatment of choice in burns for more than 100 years...

A 17-month-old female doberman pinscher was referred for an abdominal mass and ascites. Exploratory laparotomy revealed the presence of a large neoplastic mass replacing the right ovary and associated with multiple mesovarian, mesometrial and peritoneal nodules. An ovariohysterectomy was performed. Grossly, the tumour was soft and multilocular with large areas of haemorrhage and necrosis. Microscopically, it was infiltrative and composed of round and polygonal cells arranged respectively in solid sheets or forming distorted tubular structures separated by thick fibrovascular septae...

Prolonged or incomplete healing of the foot and ankle can pose significant challenges. Therefore, investigators have begun searching for alternative treatment strategies. With advances in tissue engineering, decellularized human placental connective tissue matrix has been suggested as a means to achieve more rapid and complete healing for various soft tissue and bone procedures. Basic science and clinical studies have shown that decellularized human placental connective tissue matrix can support regenerative healing through cellular migration, accelerated tissue remodeling, and the establishment of functional tissue...

BACKGROUND: Congenital heart defects are the most common birth defects worldwide. Although defective Notch signaling is the major cause of mouse embryonic death from cardiovascular defects, how Notch signaling is regulated during embryonic vasculogenesis and heart development is poorly understood. METHODS AND RESULTS: Regulator of G protein signaling 6 (RGS6)-/-/Ca2+/calmodulin-dependent protein kinase II (CaMKII)VV double mutant mice were developed by crossing RGS6-/- mice with mice expressing an oxidation-resistant CaMKIIδ (CaMKIIVV), and the resulting embryonic defects/lethality were investigated using E7...

Background: Children born to mothers with placental malaria (PM) have been described as more susceptible to the occurrence of a first malaria infection. However, whether or not these children remain more at risk during infancy has never been explored. We aimed to determine if children born to mothers with PM are more susceptible to malaria and remain at higher risk between birth and 18 months. Methods: 550 children were weekly followed-up with control of temperature and, if >37...

It is currently controversially discussed whether mesenchymal stem cells (MSC) facilitate cartilage regeneration in vivo by a progenitor- or a nonprogenitor-mediated mechanism. Here, we describe a potentially novel unbiased in vivo cell tracking system based on transgenic donor and corresponding immunocompetent marker-tolerant recipient mouse and rat lines in inbred genetic backgrounds. Tolerance of recipients was achieved by transgenic expression of an immunologically neutral but physicochemically distinguishable variant of the marker human placental alkaline phosphatase (ALPP)...

BACKGROUND: The placenta is a most interesting but unfortunately often ignored and misunderstood organ. Placental abnormalities, therefore, can be an "early warning system" for fetal problems. A complete prenatal sonographic examination of the placenta is an essential component as its abnormalities can have a direct effect on fetal or maternal outcomes, obstetrical management and future fertility. OBJECTIVE: To determine whether any association exists between the finding of an increased thickness of placenta, abnormal placenta shape, placental calcification, placental lake and abnormal cord insertion site at 20-22 and 30-32 weeks gestation with an increased risk of uteroplacental complications or a poor pregnancy outcome...

Gestational diabetes mellitus (GDM) is still a clinical challenge around world. Inflammation contributes to the pathogenesis of GDM, the precise underlying mechanism remains to be explored. IL-37 and 38 play important role in autoimmunity, but their role in the development of GDM is unclear. Using histopathology and immunohistochemistry, the thickness of the umbilical artery, the area of capillaries within the placental chorionic villi, and the production of IL-37/38 were determined. Placental mRNA of IL-37/IL-38 from GDM and Non-GMD was measured using qRT-PCR...

BACKGROUND: Cerebral Palsy (CP) is the most common physical pediatric neurodevelopmental disorder and spastic diplegic injury is its most frequent subtype. CP results in substantial neuromotor and cognitive impairments that have significant socioeconomic impact. Despite this, its underlying pathophysiological mechanisms and etiology remain incompletely understood. Furthermore, there is a need for clinically relevant injury models, which a) reflect the heterogeneity of the condition and b) can be used to evaluate new translational therapies...

INTRODUCTION: Placental thickness in the second trimester of pregnancy has been associated with risks of placenta-mediated complications of pregnancy. We aimed to estimate the association between first-trimester maximum placental thickness and the subsequent risk of preeclampsia and/or the delivery of small-for-gestational-age (SGA) neonate. METHODS: Prospective cohort study of women recruited at 11-14 weeks gestation. Placental thickness was measured at its apparent center and reported in multiple of median (MoM) adjusted for gestational age...
