Background and purpose: One of the recent techniques for increasing the output of cryopreservation is using different scaffolds in long-term preservation of stem cells for cell therapy. Undesirable differentiation and decrease in the number of viable cells are two major problems in this process. In order to overcome these problems, in this study the human amniotic epithelial cells were cryopres...
Introduction & Objective: One of the important issues in long term storage of cells is removal of animal serum from cell culture environments. The aim of this study was to evaluate amniotic fluid (AF), which is full of growth factors, as substitute for fetal bovine serum (FBS) in the cryopreservation protocol. Materials & Methods: In this experimental study human amniotic epithelial cells wer...
Introduction: Nowadays, the effects of radiation and constant use of cell phones have led to some problems. These radiations cause disorders in different systems of human body and even in a growing fetus. The aim of this study was to find the effect of using cell phone and internet by pregnant women on the amount of amniotic fluid. Method: First, a questionnaire was designed and evaluated by o...
OBJECTIVE Cervical length measurement has been uggested as a useful tool for predicting intra-amniotic infection/inflammation in preterm labor, but little information is available in the setting of preterm premature rupture of membranes (pPROM). We aimed to determine whether a short cervical length is independently associated with an increased risk of intra-amniotic infection or inflammation an...
BACKGROUND Oligohydramnios (reduced amniotic fluid) may be responsible for malpresentation problems, umbilical cord compression, concentration of meconium in the liquor, and difficult or failed external cephalic version. Simple maternal hydration has been suggested as a way of increasing amniotic fluid volume in order to reduce some of these problems. OBJECTIVES The objective of this review w...
The purpose of this study was to evaluate whether hepatocyte growth factor (HGF) concentrations in the early second-trimester amniotic fluid predict fetal growth at birth. HGF and insulin-like growth factor-I (IGF-I) concentrations in the early second-trimester amniotic fluid were measured in 12 pregnancies with small for gestational age (SGA) infants, 84 pregnancies with appropriate for gestat...
Amniotic band syndrome is an uncommon pathological condition that can lead to intrauterine fetal demise .We report an unusual case of amniotic band presentation attached to fetal head in which umbilical cord got strangulated and resulted to fetal loss.
Potential limitations of prenatal diagnosis of hemophilia B, as compared to hemophilia A, include (1) occurrence of far more frequent defects with abnormal circulating antigen, (2) lower levels of factor IX in fetal plasma at 16 to 20 weeks gestation, and (3) the presence of factor IX antigen in amniotic fluid. In addition, proteolysis could occur, especially with amniotic fluid contamination o...
Amniotic fluid embolism is a rare, yet catastrophic event. In the United States it occurs in 1 per 20,000 to 30,000 births. With an 86% maternal mortality rate, amniotic fluid embolism is responsible for 10-15% of all maternal deaths. This article presents a case study of a CNM's experience with a maternal and fetal death resulting from an amniotic fluid embolism. Pathogenesis and appropriate m...
