<strong>Background: </strong>Preterm birth is one of the primary causes of perinatal mortality and morbidity. Pregnancy-related conditions causing preterm labor are associated with gross morphological changes in placenta, the fetomaternal organ which is vital for maintaining pregnancy and for promoting intrauterine growth of the fetus. Aims of this study to the morphological variations of human placenta in preterm labor and compare the findings of the study with the morphology of human placentae of normal pregnancies and correlate the morphologic changes of the placenta in preterm labor w

The dromedary camel (Camelus dromedarius) fetal membranes, commonly referred to as “the placenta”, are epitheliochorial, diffuse, and microcotyledonary, similarly to the mare’s placenta. The evaluation of the placenta is an essential component of the neonatal evaluation in the equine species. However, post-partum or post-abortion placental assessment in dromedary camels is unfortunately too frequently neglected and, to the best of the authors’ knowledge, the dromedary camel species lacks a comprehensive description of the normal placenta’s gross morphology. In order to facilitate its on-field

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.

<strong>Introduction: </strong>The development of foetus is mainly dependant on normal placental development Pregnancy induced hypertension (PIH), a well-known complication of pregnancy is significantly responsible for perinatal morbidity and mortality due to its effects on the growing foetus. Pregnancy induced hypertension causes considerable changes in the histopathology of placental tissue. The main aim of the present study record the data on the morphology and histology of placenta from mothers with PIH and correlate the findings with the birth weight of the new born babies, severity

Species from all extant families of marsupials and monotremes were examined to clarify whether these mammalian subclasses possess brown adipose tissue. To optimize the chance of finding this tissue, special emphasis was given to sampling species adapted to colder regions, species with small adult body size, and individuals at a stage of development equivalent to the newborn stage of placentals (late pouch life in the case of marsupials). Evidence based on gross morphology and light, electron, and fluorescence microscopy failed to show the presence of brown adipose tissue in any marsupial or mo

Gestational trophoblastic disease (GTD) is a heterogeneous spectrum of diseases with abnormal trophoblastic proliferation ranging from benign to malignant state. It has varying degree of spread from local invasion to distant metastasis. These disease are characterized by a reliable tumor marker, which is the b-subunit of human chorionic gonadotropin (b-hCG), and have varied tendencies for local invasion and spread. Benign lesions consist of hydatidiform moles, complete and partial, whereas malignant lesions consist of invasive moles, placental-site trophoblastic tumors (PSTT), epithelioid trop

Our objective was to use factor analysis as a data reduction tool to organize a large number of placental pathologic features into useful aggregates. We examined 1146 placentas of live-born infants with a birth weight of 500–1500 g. We then conducted analyses of pairs of characteristics and multiple characteristics to identify “associated groups” and “factors,” respectively. We found an associated group and factor that had placental features associated with acute inflammation and another associated group and factor that had features associated with vasculopathy.

Production of cloned piglets, using normal or transgenic donor cells, has been of limited efficiency. One reason could be breed differences between recipient and embryos. The aim of this study was to compare pregnancies after transfer to Large White (LW) sow recipients of cloned LW embryos or cloned, transgenic minipig embryos. Large White donor cells were from LYxD, and minipig cells were transgenic with 1 of 5 genes related to different human diseases and from either Göttingen or Yucatan.

Placenta accreta spectrum (PAS) refers to a range of abnormally adhesive and penetrative placental tissues in the myometrium. It is critical to diagnose PAS before delivery, as maternal morbidity/mortality can occur due to life-threatening hemorrhage. Ultrasound has traditionally been the first-line imaging modality for the diagnosis of PAS; however MRI is a useful supplemental modality in the workup and is a valuable tool in cases where ultrasound is limited or equivocal. It is also indicated in further assessment of PAS in cases with a positive ultrasound diagnosis. There are three main cate

Striking microscopic changes take place in canine endometrium morphology during placentation. Gross structure (zonary placentation) and nature of maternal-fetal interface (endotheliochorial) is generally well understood. However, histological changes in endometrial tissue proper and how they impact fertility assessment utilizing histology may be less well understood. This review will cover evaluation of canine placenta (gross and microscopic), difficulties in correlating histologic evaluation to fertility and fetal loss, and implications in interpreting histopathology results.

Besides a mild increase in body temperature in four heifers, no clinical signs of infection were observed, but 5 animals aborted between days 54 and day 202 after exposure.

Cats are different from dogs, and many questions remain open concerning the establishment of pregnancy. In cats, as in dogs, no feto-maternal signaling leading to establishment of pregnancy is known. But as opposed to dogs, the placenta is a source of steroid hormones and corticotropin-releasing hormone (CRH). Scarce information is available on physiological mechanisms at the uterine level during early gestation; more studies are needed on lymphocyte subsets, feto-maternal crosstalk and other mechanisms leading to local immunosuppression, allograft acceptance and embryo nidation and invasion.

This fulfils many of the requirements of an ideal genetic cell marker and has been widely used for lineage studies with mouse chimaeras. However, it is not known whether it causes cell selection or influences developmental processes, such as cell mixing, in chimaeric tissues. In the present study, nontransgenic genetic ma

The high rates of embryonic mortalities which follow in vitro production of ruminant embryos have emphasized the need for increased knowledge of early development. It is likely that early failures in embryonic development and placenta formation involve abnormal differentiation of mesoderm. The aim of this study was to investigate the pattern of expression of two T-box genes known to control the gastrulation process, Brachyury and Eomesodermin, by whole-mount in situ hybridization. To allow a more precise comparison of both expression patterns between embryos, we describe a new staging of pre-i
