The effect of prenatal lead acetate exposure was studied microscopically together with the concentration of lead and lipid fluorescent products (LFP) in the brain of rat fetuses. Wistar rats were intoxicated with a lead solution containing either 160 or 320 ppm of lead acetate solution during 21 days through drinking water. The control group (ten rats) received deionized water for the same peri...

Umbilical cord blood is an alternative hematopoietic stem cell source for patients with hematologic diseases who can be cured by allogeneic hematopoietic cell transplantation. Initially, umbilical cord blood transplantation was limited to children, given the low cell dose infused. Both related and unrelated cord blood transplants have been performed with high rates of success for a variety of h...

OBJECTIVE To investigate the cost-effectiveness of private umbilical cord blood banking. METHODS A decision-analytic model was designed comparing private umbilical cord blood banking with no umbilical cord blood banking. Baseline assumptions included a cost of $3,620 for umbilical cord blood banking and storage for 20 years, a 0.04% chance of requiring an autologous stem cell transplant, a 0....

he lack of maternal rejection of the allogenic fetus, suggests that adaptation of the immune system occurs during normal pregnancy. Umbilical cord blood (UCB) cells have unique properties to overcome the maternal rejection of allogenic fetus. Human umbilical cord blood cells (UCBC) has been shown to be an effective source in allogenic stem cell transplantation, however there is concern due for ...

Background & Objective: Type1 diabetes is characterized by autoimmune destruction of pancreatic β cells, leading to reduced insulin secretion. Differentiation of mesenchymal stem cells (MSCs) into β-like cells offers new ways of diabetes treatment. MSCs can be insulated from the human umbilical cord tissue and differentiate into insulin-producing cells. Material & Methods: Human um...

The Stillbirth Collaborative Research Network recently reported on the probable or possible cause of death of 512 stillbirths whose mothers consented to complete postmortem examination [1]. Umbilical cord accidents (UCA) represented 10% of stillbirths [1]. In Caucasians the UCA associated stillbirth rate was 13% and 4% in non-Hispanic black. 9% of stillbirths were due to hypertension and 8% due...

Brain injuries that caused by strokes (result of intra partum ischemia) are a frequent cause of prenatal mortality and morbidity with limited therapeutic options. Transplanting human mesenchymal stem cells (hmscs) indicates improvement in hypoxic Ischemic brain injury (HIBD) by secretion growth factor stimulating repair processes (Hmscs) known as multi potent cells which isolated from bone marr...

Umbilical cord blood is the baby's blood left over in the umbilical cord and placenta after a baby is delivered and the cord is cut. Cord blood has all of the features of regular blood, but it is also a rich source of hematopoietic stem cells. Hematopoietic stem cells are unspecialized cells that produce all blood cells. These include: • Platelets, which are needed for blood clotting • Red...

Fifty umbilical cords were prepared and examined and their venous perfusion pressures measured with and without a true knot in the cord. Contrary to information in the literature, a loose umbilical cord knot did not affect the venous perfusion pressure. With a tightened knot, the smaller the umbilical cord diameter, the greater was the pressure required to perfuse past the knot. The umbilical v...
