umbilical cord blood (ucb) as a source of hematopoietic stem/progenitor cells (hspcs) used for umbilical cord blood transplantation (ucbt). the main obstacle in application of this source as an appropriate source of hspcs is low volume of this product. so ex vivo expansion of these cells in a microenvironment which mimic body condition is important. in current study we designed biocompatible mi...

background the aim of this study was the ex vivo expansion of umbilical cord blood hematopoietic stem cells on biocompatible nanofiber scaffolds. materials and methods cd133+ hematopoietic stem cells were separated from umbilical cord blood using midimacs (positive selection) system by means of monocolonal antibody cd133 (microbeads) subsequently, flowcytometry method was done to assess the pur...

background: leptin is a protein product of obesity gene and is synthesized mainly by adipose tissue. objective: the aim of this study was to determine maternal and neonatal serum leptin levels in term preeclamptic and normal pregnancies. materials and methods: this cross sectional study was performed on 37 preeclamptic and 40 normotensive term pregnant women without other disease. serum level o...

Background: The case of iron deficiency anaemia in infants is a serious health problem because it interferes with mental and cognitive development. DCC prolongs blood flow from the placenta to baby through umbilical cord, increases volume, optimizes oxygen transfusion which might prevent anemia promote effective self-breathing. Objective: To determine effect on Haemoglobin Levels Oxygen Saturat...

here are several reasons to answer yes. The first one is hat it is among the most frequently performed medical or paramedical) interventions in human beings: 3,000,000 imes a year in Brazil, 131,000,000 times a year in the world that means 250 times a minute). Therefore, even a minial influence of the way or of the timing of cord clamping n the infants’ health becomes important, because of its ...
