background: the objective of the study was to evaluate the presence of neospora caninum organisms in the brain of aborted fetuses and placentas of full-term calves born of seropositive cows. methods: during 2006-2007, 12 brains of aborted calves from neospora seropositive cattle and 7 placentas from seropositive dams giving birth to full-term calves, from four dairy cattle farms located around...
Automobile crashes are the largest cause of death for pregnant females and the leading cause of traumatic fetal injury mortality in the United States. Computational models, a useful tool to evaluate the risk of fetal loss in motor vehicle crashes, are limited to quasi-static material properties of the placenta. This study presents a total of 8 dynamic uniaxial tension tests on the full thicknes...
OBJECTIVE In previous studies it has been emphasized that the site of morphine action may be either in the embryo or the placenta. In the present study, we attempt to identify the site of morphine action on the fetal section of Wistar rat placenta by using C(14)-morphine. MATERIALS AND METHODS IN THIS STUDY (EXPERIMENTAL), FEMALE WISTAR RATS (WEIGHTS: 170-200 g) were mated with male rats and ...
Thyroid hormones (THs) must pass from mother to fetus for normal fetal development and require the expression of placental TH transporters. We investigate the compensatory effect of placental organic anion transporting polypeptide 1c1 (Oatp1c1) and monocarboxylate transporter 8 (Mct8) on maternal thyroid dysfunction. We describe the expressions of these two transporters in placental barriers an...
Background: Awareness of fetal gender at primary stages of pregnancy is very important. Fetal sex determination can reveal pressing information regarding fetal health. One of the methods of determining gender in the first trimester is according to the location of placenta. . This study investigated the accuracy and sensitivity of this method with trans-abdominal ultrasound in determining the se...
Objective(s): The mechanism via which genistein, the major isoflavone content of soya, adversely influenced placenta and fetal development was evaluated in pregnant laboratory rats.Materials and Methods: There were control, 2 mg/kg and 4 mg/kg genistein groups of rats with five sub-groups based on gestation termination day. At the end of...
Background and purpose: Around three million fetuses lose their life before birth each year. Recognizing the risk factors of these deaths could help in controlling and preventing at least a number of them. This study was conducted to determine the risk factors for uterine deaths. Materials and methods: This cross-sectional study was conducted in 225 cases of fetus uterine deaths aged >20 week ...
Several major vascular tissues, such as the aorta-gonad-mesonephros region (AGM), yolk sac, and fetal liver have been confirmed to possess hematopoietic function. Recently, the placenta has been demonstrated as another hematopoietic organ. However, it is not conclusive whether the placenta possesses hematopoietic ability. Therefore, we undertook a series of experiments to study the hematopoieti...
Background: The placenta is the most important organ for the development of the embryo and fetus because of its transport functions. Over the past several decades, a small number of proteins were tested that can cross the placenta, however, there have been no high throughput and comprehensive studies of protein crossing of the placenta. Methods: To evaluate the in situ perfused placenta model a...
Background and Objectives: Vital signs, including breathing, heart beat or involuntary movement of voluntary muscles, during child birth show that the fetus is healthy. Fetal death or still birth is one of the most complicated issues in medical science. Several factors contribute to still birth which are divided into maternal, fetal and placental groups. The present study deals with placental...
