Introduction: The aim of study was to compare umbilical cord blood selenium levels in respiratory distress syndrome (RDS) and non RDS preterm babies.    Methods: Umbilical cord blood selenium levels of all preterm newborn born during a 6-month period were enrolled in the study. They were divided into two groups: RDS and non RDS. Selenium level was assessed by using electro-thermal atomic ab...

Raised values of creatine kinase BB (CKBB) in umbilical cord serum were obtained with some normal babies and those with fetal distress. Further investigation showed that the umbilical artery and vein tissue contain high CKBB activity, indicating that some cord blood samples may not solely reflect CKBB liberated from the brain.

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...

Umbilical cord mesenchymal stromal cells (MSC) have been widely investigated for cell-based therapy studies as an alternative source to bone marrow transplantation. Umbilical cord tissue is a rich source of MSCs with potential to derivate at least muscle, cartilage, fat, and bone cells in vitro. The possibility to replace the defective muscle cells using cell therapy is a promising approach for...

Stem cell based treatments are being increasingly explored for their possible potential to treat various cancers. Mesenchymal stem cells believed to possess anti-tumor potential and are preferred for their properties like immune privileged nature, ability to migrate to the site of tumor and capability for multilineage differentiation. This tumor tropism property of MSCs could be utilized to del...

BACKGROUND As measurement of arterial oxygen saturation (SpO2) is common in the delivery room, target SpO2 ranges allow clinicians to titrate oxygen therapy for preterm infants in order to achieve saturation levels similar to those seen in normal term infants in the first minutes of life. However, the influence of the onset of ventilation and the timing of cord clamping on systemic and cerebral...

The umbilical cord is a structure that provides vascular flow between the fetus and the placenta. It contains two arteries and one vein, which are surrounded and supported by gelatinous tissue known as Wharton's jelly. There are many umbilical cord abnormalities that are related to the prognosis of fetus survival and birth weight. The authors report a case of umbilical cord constriction due to ...
