conclusion our study revealed that the hypoplastic umbilical artery group’s non-dominant cia had higher ri values than the contralateral dominant cia. results eleven of the 165 patients (6.7%) demonstrated a hypoplastic umbilical artery. second-trimester us showed median dominant and non-dominant cia pi values of 1.43 and 1.60 (p = 0.062), respectively, and median dominant and non-dominant cia ...

introduction: recognition of human leukocyte antigens (hla) is of importance for hematopoietic stem cell transplantation. any hla-mismatches between the donor and recipient can cause graft rejection or other complications. in hla-typing experiments, usage of hla-known reference cells accompany with hla-unknown samples is obligatory. some international centers represent these cells with high exp...

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...

  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 ...

Background: In this study, we examined a new two step induction protocol for improving the differentiation of human umbilical cord blood-derived mesenchymal stem cells into neural progenitor cells. Materials and Methods: Human umbilical cord blood-derived mesenchymal stem cells were first cultured in Dulbecco’s modified eagle medium supplemented with 10% fetal bovine serum in a humidified incu...

Background: The timing of umbilical cord clamping may affect the need to bloodtransfusion and other morbidities of preterm infants. This study aimed to compare three different cord clamping timing (immediate cord clamping, delayed cord clamping and umbilical cord milking) in preterm infants delivered by cesarean section (CS). <em...

Amale neonateweighing 3838 g was born at 39weeks of gestation by elective cesarean delivery due to breech presentation. The umbilical cord was clamped by the surgeon approximately 20 cm from the umbilical base and the neonate was transferred to the midwife for final clamping. The cord was clamped again at approximately 3 cm from the umbilical base. The residual umbilical cord was approximately ...

introduction: in 1989, the first successful umbilical cord blood transplantations (ucbts) was reported in a boy with fanconi's anemia, using umbilical cord (ucb) of his hla matched sister. cord blood transplantation is a good substitute for bone marrow or peripheral blood transplantation especially for children and small body size adults. methods: between 1998 and 2007 ,14 children(10 boys and ...

Approximately 2% of low-risk pregnant women still require an emergency Cesarean section after the onset of labor. Because it is likely that half of these cases are associated with placental and umbilical cord abnormalities, it is thought that prenatal detection of such abnormalities would reduce the number of emergency cesarean sections in low-risk women. Velamentous cord insertion is an abnorm...
