OBJECTIVE This study aimed to evaluate the placental weight, volume, and density, and investigate the significance of placental ratios in pregnancies complicated by small for gestational age (SGA), preeclampsia (PE), and gestational diabetes mellitus (GDM). METHODS Two hundred and fifty-four pregnant women were enrolled from August 2005 through July 2013. Participants were divided into four g...
Objective(s): The present day challenge is how to obtain germ cells from stem cells to treat patients with cancer and infertility. Much more efforts have been made to develop a procedure for attaining germ cells in vitro. Recently, human umbilical cord-derived mesenchymal stem cells (HUMSCs) have been introduced with higher efficacy for differentiation. In this work, we tried to explore the eff...
ABSTRACT Background and Objective: Multipotent placental amniotic membrane mesenchymal stem cells (MSCs) are capable of differentiating into specialized tissues under different conditions. The aim of this study was to induce differentiation of placental amniotic membrane MSCs from NMRI mouse into hepatocytes using liver extract. &nb...
Abstract Absences pose a dilemma for theories of causation. Allowing them to be causes seems make too permissive. Banning from being restrictive. An increasingly popular approach this is acknowledge that norms can affect which absences count as causes. In article, I distinguish between two influential implementations such ‘abnormality’ approaches and argue so-called ‘double-prevention mechanism...
There are a limited number of artistic objects from ancient times with particular importance in neonatal medicine. The best examples are figurines from ancient Egypt of Isis nursing Horus, showing the importance of breastfeeding. The earliest images of the human fetus were made by the Olmecs in Mexico around 1200- 400 BCE. One of the earliest representations of congenital anomalies is a figurin...
Estimating placental oxygen transport capacity is highly desirable, as impaired placental function is associated with fetal growth restriction (FGR) and poor neonatal outcome. In clinical obstetrics, a noninvasive method to estimate the placental oxygen transport is not available, and the current methods focus on fetal well-being rather than on direct assessment of placental function. In this a...
Background: Early detection of fetal gender can provide an alarm for parents who complicated by genetic disorders. Moreover, the invasive tests are used for detecting any sex-specific genetic syndromes before 12 weeks of gestation. This study was de-signed to discover any association between placental location and fetal gender between 11 to 13+6 weeks of gestation. Methods: A cross-sectional s...
