objective: to compare the maternal and umbilical cord serum selenium concentrations in low and normal birth weight neonates. materials and methods: a case-control study was carried out in vali-asr and akbarabadi hospitals (jan. to dec. 2013). two groups; case group; 91 mothers who delivered a low birth weight (lbw) neonate and control group; 86 subjects who delivered a normal birth weight neona...
Background: Previous studies have suggested the presence of a relationship between the increase of NRBC and the duration and intensity of asphyxia. The purpose of this study was to evaluate the relationship of fetal heart rate pattern and the number of NRBC's in umbilical cord blood sample at birth. Methods: We enrolled 322 pregnant women with healthy, term fetuses who referred to Mirza Koucha...
BACKGROUND Wound healing is a complex and dynamic process following damage in tissue structures. Due to extensive skin damage caused by burn injuries, this study determined the role of human adult peripheral and umbilical cord blood platelet-rich plasma on proliferation and migration in human skin fibroblasts. METHODS Platelet-rich plasma (5, 10, 15, 20 and 50% PRP) from human umbilica...
microrna modulation during the in vitro culture of hematopoietic stem cells prior to transplantation
background: human umbilical cord blood (hucb) is an acceptable and readily accessible source of stem cells. there is an ongoing interest in cord blood stem cell therapies; however, little is known about the possible unfavorable effects of laboratory modifications on the isolated hucb cells. the involvement of mirnas in several biological processes has been shown. the aim of this study was to ev...
background: in recent years we have successfully adopted an in vitro hepatogenic differentiation of mesenchymal stem cells (mscs). in this protocol the biologically active hepatocyte-like cells were differentiated from the stem cells isolated from either bone marrow or umbilical cord blood (ucb) samples. the aim of the present study was to compare the efficiency of the hepatogenic differentiati...
stem cells are naïve or master cells. this means they can transform into special 200 cell types as needed by body, and each of these cells has just one function. stem cells are found in many parts of the human body, although some sources have richer concentrations than others. some excellent sources of stem cells, such as bone marrow, peripheral blood, cord blood, other tissue stem cells and hu...
This study was conducted to assess the role of maternal oxygen administration during the second stage of labor on umbilical cord blood gas values. This study was done in Fatemieh hospital on 160 pregnant women who were admitted for vaginal delivery and had the inclusion criteria. A group ...
Background: True umbilical cord knot is one of the abnormalities of the umbilical cord. Active fetal movements create cord knotting. True umbilical cord knots are rare but may be associated with fetal distress and stillbirth. True umbilical cord knots are capable of impeding blood flow to the fetus.Case presentation: A 26-year old primigravid woman was first treated for genital herpes simplex v...
Background: Entanglement of the umbilical cord around fetal neck has been reported to be associated with birth asphyxia. On the other hand, current evidence suggests that umbilical arterial pH analysis provides the most sensitive reflection of birth asphyxia. In this study we aimed to evaluate and compare the umbilical arterial hydrogen-ion concentration (pH) and to analyze the blood gases of n...
conclusions our results suggested that cb-nk cells progenitors could proliferate and differentiate on feeder layer of amnion membrane mscs in combination with specific cytokines to produce nk cells for immunotherapy. results combination of cytokines and msc layer yielded significant fold expansion in comparison with cytokines without feeder conditions (day 7: 5.2 ± 1.12 and 2 ± 0.78, respective...
