Umbilical cord blood (UCB) stem cells [4] are hematopoietic stem cells [5] (HSC) that are recovered from the blood of the umbilical cord [6] and placenta [7] after birth. Umbilical cord blood is rich in cells that express the CD34 molecule, a surface protein that identifies cells as stem cells [4]. Prior to the discovery of UCB stem cells [4], it was standard procedure to discard the umbilical ...

BACKGROUND There are no definitive markers to aid in diagnosis of neonatal encephalopathy (NE). The purpose of our study was (1) to identify and evaluate the utility of neuronal nitric oxide synthase (NOS1) in umbilical cord blood as a NE biomarker and (2) to identify the source of NOS1 in umbilical cord blood. METHODS This was a nested case-control study of neonates >35 weeks of gestation. E...

total serum copper levels of 70 pregnant women hospitalized for delivery at misaghieh (private), 90 at farah (public) maternity hospitals immediately after delivery and 27 non-pregnant women (control) were measured. the copper level in the blood serum of umbilical cord of the newborn infants was also determined. the copper levels were significantly elevated in both pregnant groups as compared t...

conclusion reference ranges for umbilical cord csa have been generated. the csa of the umbilical cord and other components of it increase as a function of gestational age. these measurements correlate with fetal size. results the values of the csa of the umbilical cord, umbilical vein and wharton’s jelly (wj) increase consistently until 30 weeks of gestation, after which they reach a plateau. t...

OBJECTIVE To investigate the potential value of uterine artery (UtA) Doppler at 30-34 weeks' gestation in the prediction of adverse perinatal outcome. METHODS This was a screening study in 30 780 singleton pregnancies at 30-34 weeks. UtA pulsatility index (UtA-PI) was measured and the values were converted to multiples of the median (MoM) after adjustment for variables relating to maternal ch...

Umbilical cord blood stem cell transplants are used to treat a variety of oncologic, genetic, hematologic, and immunodeficiency disorders. Physicians have an important role in educating, counseling, and offering umbilical cord blood donation and storage options to patients. Parents may donate their infant's cord blood to a public bank, pay to store it in a private bank, or have it discarded. Th...

Objective: In this study, we aimed to investigate umbilical cord blood CD33 and erythropoietin (EPO) levels of pregnants with abnormal umbilical and uterine artery doppler waveforms and to compare with normal pregnancies. Materials and Methods: Total 40 pregnant women were included in this study. Of these 40 women, while 20 patients had abnormal umbilical and uterine artery doppler waveforms, t...

Since the first umbilical cord blood transplantation (CBT) in 1998, cord blood (CB) has now become one of the most commonly used sources of hematopoietic stem cells for transplantation. CBT has advantages of easy procurement, no risk to donor, low risk of transmitting infections, immediate availability and immune tolerance allowing successful transplantation despite human leukocyte antigen disp...

Umbilical cord blood transplantation (CBT) has been widely used as an alternative source of hematopoietic cell support for stem cell transplant patients. CBT offers several advantages over traditional stem cell sources, such as immediate availability, absence of risk for donors, lower risk of acute graft-versus-host disease, and a less stringent requirement for human leukocyte antigen matching....
